To Our Shareholders:

I am pleased to report that Fiscal 2007 was a record year of profitability for AspenTech®. Our operating

performance in Fiscal 2007 continued the turnaround in the company’s operating performance that

started in Fiscal 2006. Our success was due to continued strength in our core markets, the adoption of

integrated aspenONE™ solutions by our customers, and solid execution by our employees.

Fiscal 2007 was also marked by financial reporting delays, which ultimately resulted in the delisting of

our common stock from the NASDAQ Global Market. Although we were pleased with our operating

performance, the financial reporting delays and their overshadowing of our strong operating

performance have been a disappointment. We have been working diligently to become current in our

financial reporting. In April 2008 we completed and filed our Fiscal 2007 financial statements,

restatement of past years’ financial statements, and our Fiscal 2008 first quarter results. In addition,

we began working on the Fiscal 2008 second and third quarter financials, and KPMG began its

engagement as our new independent registered public accounting firm. We appreciate your patience

and support as we finish this work. On an operational level, we continue to improve and have

significant opportunity over the long term.

Actual results may vary significantly from
AspenTech’s expectations based on a number of
risks and uncertainties, including, without
limitation: AspenTech’s plan to improve
operational performance may not be
implemented effectively; AspenTech has
identified material weaknesses in its internal
controls with respect to software license revenue
recognition and other matters, that, if not
remedied effectively, could result in material
misstatements; AspenTech may incur substantial
damages and expenses as the result of pending
and future securities litigation and government
investigations, including securities litigation
based on the restatements of the company’s
financial statements as well as any future action
associated with a determination that the
company has failed to comply with its existing
consent decree with the Federal Trade
Commission; AspenTech’s lengthy sales cycle
makes it difficult to predict quarterly operating
results; fluctuations in AspenTech’s quarterly
operating results; AspenTech’s dependence on
customers in the cyclical chemicals,
petrochemicals and petroleum industries; the
possibility of new accounting standards or the
interpretation of existing accounting standards
affecting our financial results; AspenTech’s ability
to raise additional capital as required; intense
competition; AspenTech’s need to develop and
market products successfully; reliance on
relationships with strategic partners; challenges
associated with international operations; risks
associated with AspenTech’s delisting from The
Nasdaq Stock Exchange and the trading of
AspenTech’s common stock over the counter;
and other risk factors described from time to time
in AspenTech’s periodic reports filed with the
Securities and Exchange Commission.
AspenTech cannot guarantee any future results,
levels of activity, performance, or achievements.
AspenTech expressly disclaims any current
intention to update forward-looking statements
after the date of this press release.

Revenue, Profitability, and Margin Growth

The strong operational performance in Fiscal 2007 extended across all three of our major product lines:

Engineering, Plant Operations, and Supply Chain. This growth reflects the ability of our products to

generate significant benefits for our customers, as well as the breadth and depth of our customer

relationships. It also reinforces the acceptance of aspenONE solutions in leading the industry-wide

transition toward more integrated software solutions.

In Fiscal 2007 we achieved total revenue of $341.0 million, an increase of 16% from the prior year’s

total of $294.4 million. License revenue increased by 30%, from $153.7 million in Fiscal 2006 to

$199.8 million in Fiscal 2007. Services revenue increased by 0.4% from $140.7 million in Fiscal 2006

to $141.3 million in Fiscal 2007.

We also achieved record profitability in Fiscal 2007. Operating profit increased to a record $55.4 million

in Fiscal 2007, an increase of 195% from $18.8 million in Fiscal 2006. Net income increased to

a record $38.2 million in Fiscal 2007 from an $8.9 million loss in Fiscal 2006.

Margins improved across the board in Fiscal 2007. Gross margin increased from 67% in Fiscal 2006

to 73% in Fiscal 2007. Operating margin increased from 6.4% in Fiscal 2006 to 16.2% in Fiscal 2007.

Net income margin increased from (3.0%) in Fiscal 2006 to 11.2% in Fiscal 2007.

Solid Demand Across Core Markets

The process industries continued to grow in Fiscal 2007. Robust market activity continued in all of our

core markets, including energy, chemicals, and engineering and construction. As a leading application

software supplier to the process industries, AspenTech has benefited directly from this growth. A

strong global economy drove petroleum-based plant expansions and new construction throughout the

world. At the same time, existing plants operated at close to capacity, in each case leading to increased

demand for our optimization solutions. Overall, our performance exceeded analysts’ growth figures for

the process industries as a whole.

Leading the Market with aspenONE

aspenONE is the only suite of software applications available today to process manufacturers that

integrates and optimizes engineering, manufacturing, and supply chain operations. It enables our

customers to address inefficiencies across all aspects of their process operations and is already

generating significant benefits for our customers who have upgraded to aspenONE.

Fiscal 2007 continued the market acceptance of aspenONE. During the year, aspenONE solutions

accounted for 38% of license revenues, up from 27% in Fiscal 2006, demonstrating the strong

traction of this market-leading integrated suite, which we believe is still in the early stages of adoption.

We were very pleased with this performance, which we believe can be attributed to the value our

customers realized from aspenONE.

Investment in Research and Development

We continue to maintain, upgrade, and integrate our product line while increasing our investment in

new products and functionality. Over the past few years we have increased our R&D staff by a third,

begun a research program to look at future technologies, and expanded our quality control initiatives to

build better software. These investments are already yielding results. We are commercializing new

functionality for our core business, with patent applications being filed for several new exciting

technologies, and releasing new technology that will help our customers reduce CO2 emissions and
improve overall air quality. We are committed to our R&D investment to better serve our customers

and improve our competitive position. We have an opportunity, in a growing market, to help our

customers operate their business better through software. We have a very good start and we plan to

continue to expand our investments as we grow.

Valuing People and Relationships

Our customer base of more than 1,500 process manufacturers is a valuable and strategic asset. Our

success depends on our delivering and servicing leading solutions that help our customers achieve

operational excellence.

In addition, we are fortunate to have built up over time an employee base with deep industry and

technical expertise that is highly focused on our customers’ success by delivering better software and

services that increase customer value. We realize that these highly skilled individuals form the

underpinnings for our future success.

In Summary…

I am pleased with the continued operating progress since I joined AspenTech. The Company’s revenues

increased from $269.1 million in Fiscal 2005 to $341 million in Fiscal 2007. Gross margin increased

from 60% in Fiscal 2005 to 73% in Fiscal 2007 and operating margin increased from (22%) in Fiscal

2005 to 16.2% in Fiscal 2007. Finally, as stated above, profitability has been restored. After recording a

loss of $83.5 million in Fiscal 2005, we reported a record net income of $38.2 million in Fiscal 2007.

With the recent filing of Fiscal 2007 results and the engagement of KPMG as our new independent

registered public accounting firm, we believe we have made significant progress toward rectifying our

financial reporting issues. We are working to become current with our SEC filings and list on a major

national securities exchange.

We believe we are well positioned to continue to win in the marketplace. You have my commitment

that we will remain focused on executing a strategy that has proven to be successful. I look forward to

sharing the results of our Fiscal 2008 efforts with you later this year.

Sincerely,

Mark E. Fusco

President and Chief Executive Officer

This Form 10-K restates portions of our Annual Report on Form 10-K for the fiscal  year ended

June 30, 2006 as originally filed with the SEC on September 28, 2006, as amended by Amendment
No. 1 thereto filed with the SEC on November 14, 2006 and Amendment No. 2 thereto filed with the
SEC on March 15, 2007.

aspenONE, Aspen Plus, HYSYS, AspenTech and DMCPlus are our registered trademarks. Aspen

This Form 10-K contains ‘‘forward-looking statements’’ within the meaning of  Section 27A of  the
Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, which are  intended to
be covered by the safe harbors created thereby. For this purpose, any statements contained  herein that

statements involve risks and uncertainties, many of which are beyond our control, including the factors
set forth under ‘‘Item 1A. Risk Factors.’’ Although we believe that the  assumptions underlying the

forward-looking statements contained herein are reasonable, any of the assumptions could be
inaccurate and there can be no assurance that actual results will be the same as those indicated by the

EXPLANATORY NOTE

In this Form 10-K, we are restating (a) our consolidated financial statements as of June 30, 2006

and for the years ended June 30, 2006 and 2005, as set forth in ‘‘Financial Statements  and
Supplementary Data’’ in Item 8 of this Form 10-K in Note 17, and (b) our condensed consolidated
financial statements for the first three quarters of the year ended June 30, 2007 and each of the
quarters in the year ended June 30, 2006, as set forth in ‘‘Management’s  Discussion and Analysis of
Financial Condition and Results of Operations—Quarterly Results’’ in Item 7 of  this  Form 10-K. The
financial data included in ‘‘Selected Financial Data’’ in Item 6 of this Form 10-K have also  been
restated.

Subsequent to the issuance of our consolidated financial statements for the year ended  June 30,

2006 (as previously restated), and as previously announced on June  11, 2007, we identified errors
related to the accounting for sales of customer installment and trade receivables to financial institutions
or unconsolidated special purpose entities, which we refer to as ‘‘receivable  sale  facilities.’’  The  sales of
receivables were designed to meet ‘‘true sale’’ criteria for legal and accounting purposes.  The
transferred receivables serve as collateral under the receivable sales facilities and limited recourse exists
against us in the event that the underlying customer does not pay. These transactions historically had
been accounted and reported as sales of assets for accounting purposes, rather than as secured
borrowings. As further described below, however, we should  not  have derecognized the receivables and
should have recorded the cash received from the transfer of such assets as a secured  borrowing  in our
consolidated balance sheet, as we effectively retained control of these assets for accounting purposes.
As further discussed below, we also identified other errors  related to revenue recognition, income tax
accounting and classification of preferred stock dividends and accretion.

We  effectively retained control for accounting purposes of  the transferred  assets as  a result of
engaging in new transactions with our customers to sell additional software and/or extend the terms of
existing license arrangements, which were the basis for these installment receivables. The new
transactions would sometimes consolidate the remaining balance of the outstanding receivables with
additional amounts due under the new or extended software license arrangement. Some receivable sale
facilities allowed for this consolidation, subject to a limit, which was exceeded. Other receivable sale
facilities did not allow for this method of consolidation. Accordingly, the amount and/or  method of
consolidation of these receivables resulted in the lack of legal isolation of  the assets from  us, which is
one of the requirements to achieve and maintain sale accounting treatment under Statement of
Financial Accounting Standards, or SFAS No. 140,  ‘‘Accounting for Transfers and Servicing of Financial
Assets and Extinguishments of Liabilities.’’ We believe that for accounting purposes, we retained
control of the receivables transferred to the receivable sales facilities for each of the  years  in the
three-year period ended June 30, 2007 and that none of the sales of receivables during this period
qualified for sale accounting treatment under the provisions of SFAS No. 140. This accounting
conclusion does not alter the arrangements with our customers, and we do not believe that the
accounting conclusion has changed our relationship with the financial institutions, including the limited
recourse that such financial institutions have against us beyond the transferred receivables.

Our previous accounting treatment was to inappropriately account for these transactions as sales of
assets. Accordingly, under our previous accounting treatment, we immediately recognized  any gains and
losses upon the transfer of assets and then recorded a ‘‘retained interest in sold receivables’’ for our
continuing interest, if any, which was initially recorded at the estimated fair value. Our retained interest
in sold receivables was subject to periodic accretion of this interest (recorded through interest income)
through the term of the respective arrangement. No recognition of the transferred receivables or any
debt obligation was recognized for these transactions.

To correct these errors, we have recorded  the transferred receivables, which are  reported as
‘‘collateralized receivables’’ on our consolidated balance sheet, and a secured debt obligation for the

1

amount of cash received from the receivable sale facilities. There are no gains and losses recognized
upon the transfer of these assets and any costs incurred have now been recorded  as debt  issuance costs.
We  now recognize interest income from the retained installments receivable  and interest expense on
the secured borrowing. The previous accounting for the retained interest in the transferred installments
receivables, including the accretion included in interest income, has been eliminated as the entire
interest in the receivables has been included in our consolidated balance sheet. Bad debt provisions
related to the transferred receivables are now reflected in our consolidated statements of operations.
We  have also recorded the currency  exchange gains or  losses  on installments receivable that were
previously not recorded. The funding received from the receivable sales facilities was previously
recorded as cash flows from operations in our consolidated statements of cash flows. We have  corrected
the presentation to include the proceeds from and repayments of the secured borrowings as
components of cash flows from financing activities in the consolidated statements of cash flows.
Repayments of secured borrowings and operating cash  flows from collateralized receivables are
recognized upon customer payment of amounts due.

In addition, we identified other errors in our previously reported financial statements in the course
of preparing the consolidated financial statements for the year ended June 30, 2007. These  errors  relate
to the timing of revenue recognition, corrections to our income tax accounting, classification of
preferred stock dividends and accretion, and other items. Errors in  the timing  of  revenue recognition
primarily relate to the inappropriate application of American Institute of Certified Public Accountants
Statement of Position, or SOP No. 97-2, ‘‘Software Revenue Recognition’’ for certain arrangements that
bundled software licenses with services. For these bundled arrangements, we determined that  the
service element could not be accounted for separately from the software. We had deferred revenue
recognition related to the license component until the services arrangements were complete, instead of
recognizing revenue under the arrangements as services were performed. In other arrangements, we
determined that service revenue was recognized prior to the  delivery of  the software  license, and we
did not have vendor specific objective evidence, or VSOE, of fair value for the  undelivered license  or
the price on the arrangement was not fixed and determinable. In addition, revenue was recognized in
fiscal 2005 where collection was not probable as the customer did not have the ability to pay until  the
software was implemented for an end user or specified upgrades were provided. Further, a change in
the terms of an agreement occurring in fiscal 2006 was not previously recorded and should have been
reflected in fiscal 2006. We have corrected these errors and recognized revenue over the  period the
services were performed for these bundled arrangements or when the criteria  for revenue recognition
were met.

We  also identified errors in our historical income tax accounting for certain  international tax
obligations, primarily arising from errors in the application of the Company’s transfer pricing policies
for transactions among consolidated subsidiaries, failure to properly account for deemed dividends from
our consolidated subsidiaries as a result of the lack of settlement of intercompany transactions, errors
in the accounting for revaluation of foreign currency denominated transactions,  and other errors. We
have corrected the calculation of our tax provisions for these obligations in the  applicable  year,
including recognition of interest and penalties attributable to the adjusted tax provisions.

In addition, in the calculation and disclosure of deferred tax balances, the majority of which are

subject to a full valuation allowance, errors were identified in these balances and resulted in the
incorrect disclosure of our deferred taxes and the related offsetting valuation allowance within the
income tax footnote. These disclosures, along with any changes in balances reflected, are being restated
as of June 30, 2006 in the income tax footnote. The primary components which are being restated are
the federal and state loss carryforwards, foreign tax credits and other errors in the calculation of
deferred tax balances. In addition, the disclosure of the tax net operating loss should have excluded all
excess tax benefits arising from the stock compensation deductions, which upon realization, would be
reflected in additional paid-in capital. As a result, the disclosure of domestic tax loss carryforwards has

2

been reduced by $32.4 million and foreign tax credit carryforwards have increased by $19.0  million  as
of June 30, 2006. Other net deferred tax balances were increased by a total of $12.9 million. As these
deferred tax assets had and continue to have a full  valuation  allowance, corrections to the disclosure of
our deferred taxes and the related offsetting valuation allowance had an  immaterial impact on  our
consolidated balance sheets, statements of operations, and statements of cash flows.

We  also identified that dividends and accretion on outstanding  preferred stock has not been
properly classified within its stockholders’ equity accounts.  As we have been in an accumulated deficit
position, the dividends and accretion on preferred stock should have been classified as a reduction in
additional paid-in capital as opposed to increasing the accumulated deficit. As a result of this  error,
additional paid-in capital was overstated and accumulated  deficit was overstated as of June  30, 2004,
2005 and 2006 by $28.3 million, $42.8 million, and $58.1 million, respectively.

In order to correct the errors described above, we have restated our consolidated balance sheet as

of June 30, 2006 primarily to reflect (a) the recording of $211.3 million in collateralized receivables,
(b) the related recording of $182.4 million in secured borrowings supported by this  collateral, (c) the
elimination of the $19.0 million in retained interest in sold receivables (d) additional taxes payable of
$15.1 million and other accrued liabilities of $2.3 million and (e) $58.1  million reclassification between
additional paid-in capital and accumulated deficit. We have restated our  consolidated statements of
operations for the years ended June 30, 2005 and 2006 primarily to reflect (a) additional interest
income related to the collateralized receivables of $12.8 million in the year ended June 30, 2005 and
$14.9 million in the year ended June 30, 2006, (b) additional interest expense related to the secured
borrowings of $12.6 million in the year ended June 30, 2005 and $18.5 million in the year ended
June 30, 2006, (c) decreases in losses on sale and disposals of assets of $14.4 million in the year ended
June 30, 2005 and $0.6 million in the year ended June 30, 2006 related to the elimination of losses
previously recorded from the transfer of installment and accounts receivable accounted for  as a sale,
(d) additional provisions for bad debt associated with the collateralized receivables of $2.6 million in
the year ended June 30, 2005 and $1.8 million in the year ended June 30, 2006, (e) a decrease in
revenue related to certain arrangements that bundled software licenses with services  of  $0.1 million in
the year ended June 30, 2005 and an increase  of $1.7 million in the year ended June 30,  2006,  (f) a
decrease in revenue related to errors in the timing of revenue  recognition of $0.8 million in the year
ended June 30, 2005 and $0.4 million in the year ended June 30, 2006 and (g) additional provisions  for
income taxes of $6.8 million in the year ended June 30, 2005 and $3.2 million in the year ended
June 30, 2006. The corresponding impacts on the consolidated statements of cash  flows  have been
reflected for the years ended June 30, 2005 and 2006.

Overview

We  are a leading supplier of integrated software and services to the process industries, which
consist of oil and gas, petroleum, chemicals, pharmaceuticals and other industries that manufacture and
produce products from a chemical process. We provide a comprehensive, integrated  suite of software
applications that utilize proprietary empirical models of chemical manufacturing processes to improve
plant and process design, economic evaluation, production, production planning and scheduling, and
operational performance. These solutions help our customers  improve their  competitiveness  and
profitability by increasing revenues, reducing operating costs, reducing  working  capital  requirements
and decreasing capital expenditures.

We were initially incorporated in 1981 and reincorporated in Delaware in 1998. For more than
25 years,  we have had a track record of innovation and technology leadership in the  process industries.
Our customer base of over 1,500 process manufacturers includes the 30 largest petroleum  companies in
the  world,  the 50 largest chemical companies, 14 of the 15 largest pharmaceutical companies  and  14 of
the  16 largest engineering and construction firms that service the process industries.  As  of June 30, 2007,
we operated globally through 29 offices in 22 countries. We sell our products primarily through a direct
sales force, and we have established a number of strategic relationships to leverage our internal sales and
marketing  efforts, enhance the breadth of our solutions and expand our implementation capabilities.

Industry Background

The process industries consist of oil and gas, petroleum, chemicals, pharmaceuticals and other
industries that produce products from a chemical process. Process manufacturers face a number of
significant challenges that are specific to each industry. To succeed in an increasingly competitive global
environment, process manufacturers must simultaneously reduce costs and increase efficiency,
responsiveness and customer satisfaction. Because process manufacturing tends to be asset-intensive,
increases in profitability in these industries depend substantially upon reducing the costs  of  raw
materials, energy and capital. Given the large production volumes typical in the process industries and
the relatively low profit margins characteristic of many sectors within the process industries, even
relatively small reductions in raw material or energy requirements or small improvements in input costs,
throughput or product yields can significantly increase the profitability of process manufacturers.

The process industries face significant challenges because of the complex activities and supply
chains that must be managed when purchasing raw materials, manufacturing products, and delivering
final products to customers. Factors that make it difficult for these  companies to optimize these
processes and make optimal economic decisions include the following:

• products are manufactured in continuous processes that are  unpredictable and difficult to model;

• production sequence and raw material specification both have a major impact on feasibility  and

profitability;

4

• multiple, interdependent products are made simultaneously,  making production planning

complicated;

• manufacturing plants are sophisticated and extremely capital intensive;  and

• supply chain management is complex.

In addition to these factors that are common to most segments of the process industry,  each

vertical market has its own set of unique challenges that must be addressed in order to manage
operations effectively.

Oil and Gas

The upstream oil and gas sector is driven by the high cost of capital investment, which is being

exacerbated as the search for new reserves takes companies to more remote, politically unstable
locations and ever deeper oceans. The high cost of investment places a premium on getting the most
out of any expenditure. An improperly placed well that fails to economically  remove all surrounding
reserves or a poorly designed transmission system that requires  excessive pressurization or maintenance
can have a significant impact on profitability for years to come. In  addition, managing oil and gas assets
is complicated since these assets are highly complex and interconnected. Companies must  achieve high
output while minimizing investment, optimize facilities to match  a constantly varying slate of crudes and
gases, and ensure the efficient transmission of materials through large,  interconnected, and
environmentally sensitive pipeline infrastructure.

To further complicate the challenge, every decision occurs against  the backdrop  of  rapidly

fluctuating open market oil and gas prices. Unlike other segments of the process industries, where raw
material price movements are smoothed through long-term contracts, oil and gas  prices can oscillate
rapidly from week to week or even day to day. This puts enormous pressure on companies to profit
from rising prices while they can. Delayed decisions and prolonged production  ramp-ups can spell the
difference between selling into a rising or falling market.

Specifically, oil and gas companies face the following distinct  challenges  in  managing their

operations:

• managing assets as an interrelated system;

• ensuring consistently profitable price nominations and  product contracts;

• maximizing production with minimal capital  investment;

• responding faster to gas and oil price fluctuations  and operating disruptions;  and

• ensuring regulatory compliance without adding administrative overhead.

Petroleum

In the downstream petroleum industry, prices, capacity utilization and operating margins are all
reaching record highs. As a result, there is tremendous pressure on refineries to optimize their output,
maximize their product mix and minimize their inventory levels throughout the system. At the same
time, petroleum companies are recognizing that the legacy IT systems that resulted from the mergers
and acquisitions of the 1990s are inadequate. Instead, they are increasingly investing in integrated
software suites that can provide better visibility into all aspects of the production process, from
inventory levels throughout the system to quality and production information as well as market
dynamics. This enables them to keep lower amounts of inventory on hand, make better buy vs. make
vs. trade decisions and maximize capacity utilization at the refinery level taking into account both
volume and product mix. In addition, the need for accurate integrated information is further

5

exacerbated by a proliferation of regional product specifications, a volatile market,  and increasingly
stringent environmental regulations.

Running more barrels through the refinery at  top capacity  makes  it difficult  to  keep the physical
assets in prime condition and can create safety and reliability issues. Refiners  are faced with the need
to optimize the design of processes and achieve more reliable and stable operations. Process engineers
are challenged with making timely business decisions while meeting the business  objectives of designing
and operating efficient, safe and profitable process plants. Measuring the complex interactions among
equipment, feedstock, refined products and business objectives is the key to unlocking optimization at
the refinery level.

Specifically, petroleum companies face the following challenges in managing their operations:

• making timely business decisions based  on volatile  market conditions while at the  same time

operating efficient, safe and profitable refineries;

• minimizing inventory levels throughout  the system without  becoming  vulnerable  to  changes in

demand or market disruptions;

• managing the reduced supply chain flexibility created  by clean fuels legislation and the

proliferation of product specifications;

• responding effectively to changing supply/demand  balances and supply patterns; and

• optimizing the use of energy to minimize the impact of high energy  costs.

Chemicals

The chemical industry produces bulk chemicals that are true commodities  with  little  or nothing to

differentiate one company’s offering from another. The market is global and highly competitive.
Producers routinely invest to build highly  specialized, continuous process  plants that reduce production
costs to a minimum. They must continue to invest over a  plant’s lifetime to ensure it remains
cost-competitive with newer units. The most successful companies find ways to differentiate  themselves
through product quality, customer responsiveness and operating efficiency.

Chemical companies face a number of strategic challenges. They  need  to  maximize the  returns
from their expensive assets. They must manage wide swings in feedstock (raw material) costs and high
energy costs. Due to global industrial consolidation, they face increasingly concentrated  and powerful
competitors and customers, placing enormous pressures on their operating margins. This pressure has
eroded the advantages once enjoyed by companies with established market, technology or regional
positions. In the face of such intense pressure, producers have only a limited ability to raise prices and
must instead focus on optimizing their product mix and minimizing their costs throughout the
production process.

To respond to these pressures many  large chemical manufacturers are looking to replace the
‘‘patchwork’’ of point solutions that they currently use to design facilities and optimize production with
solutions that can address operational costs as a single, interrelated whole, much in the same way that
enterprise resource planning, or ERP,  systems squeezed costs from the interrelated transactions that
define back office business processes.

Specifically, chemical producers face the following challenges in managing their operations:

• identifying and correcting cost variations  when they occur;

• operating assets as one interrelated system rather than as individual  components;

• reducing plant lifecycle costs while  improving operating performance;

6

• minimizing inventory without hurting customer  service;

• responding more quickly and profitably to unexpected opportunities and disruptions; and

• ensuring regulatory compliance without adding administrative overhead.

Pharmaceuticals

Changing industry dynamics and increasing competition from generic  drug products are driving
pharmaceutical companies to improve  their operational capabilities to ensure  future profitability.  As a
result, many pharmaceutical companies are now viewing manufacturing and distribution not only as a
means of meeting demanding quality and supply criteria but also as a means of achieving competitive
advantage by reducing manufacturing costs.

Pharmaceutical companies face a number of strategic  challenges. Regulatory  agencies are

demanding strict, detailed material, process, and personnel tracking. At the  same time,  companies are
facing increased competition from generic drugs and must increasingly speed products to market to
maximize profits. To respond to these pressures, pharmaceutical companies are looking to implement
solutions that can help them meet their regulatory requirements, reduce their time to market and
decrease their production costs.

Specifically, pharmaceutical companies face the following  challenges  in managing  their operations:

• complying with strict regulatory requirements;

• improving manufacturing agility to take advantage of  new approaches and processes;

• reduce time required to scale-up production;

• improving customer service; and

• reducing the complexity of IT systems.

Process Industry Technology

Historically, technology solutions have played a major role in helping process companies to drive

productivity improvements. In the 1980s, this increase in efficiency came from the use  of  distributed
control systems, or DCS, to automate the management of plant hardware. These systems utilized
computer hardware, communication networks and industrial instruments to measure, record and
automatically control process variables. However, although DCS and ERP solutions  are important
components of a solution to improve manufacturing enterprise performance, they do not incorporate
either the detailed chemical engineering knowledge essential to optimize the  design and  operation  of
related manufacturing processes or the plant performance data required to support more intelligent
real-time decision making and therefore their influence on day-to-day operational activities is  limited.

Today, process manufacturers are seeking tools  to  help  them improve their  operating performance,

competitive position and responsiveness to increasingly volatile raw material and end markets. For
example, while rising oil prices provide an opportunity for petroleum refiners to raise their prices, they
also increase the cost of operating energy-intensive manufacturing facilities. These dynamics are
creating demand for intelligent decision-support products that can provide an accurate real-time
understanding of a plant’s capabilities, as well as accurate planning and collaborative forecasting
information.

Moreover, as process manufacturers have become more adept at using products that optimize

individual engineering, plant operations and supply chain management business processes, they
increasingly are seeking additional performance improvements by integrating these products, both with
one another and with DCS, ERP and other enterprise systems, to provide real-time, intelligent decision

7

support. To achieve these objectives, companies are implementing solutions that integrate related  business
processes within a single production facility and across multiple sites. In addition, by adding planning and
scheduling functionality, companies are extending these solutions by optimizing their supply  chains to
substantially  reduce cycle times, adjusting production quickly to meet changing customer  requirements,
synchronizing key business processes with plants and customers across numerous geographies  and  time
zones, and  quoting delivery dates more accurately and reliably. Traditional solutions  and emerging
software integration vendors lack the deep process knowledge necessary to solve the complex problems
faced by process manufacturers attempting to achieve true optimization of their  enterprises, from design
to production to management of the extended supply chain.

The AspenTech Advantage

Process manufacturers use our solutions to improve their profitability and competitiveness, not

only by reducing raw material and energy use, cycle time, inventory cost and time to market, but
increasingly by synchronizing and streamlining key business processes. Our competitive advantage  is
based on the following key attributes:

Substantial process industry expertise. By developing software for the process industries for more

than 25 years, we believe we have amassed the world’s largest collection of process industry domain
knowledge to develop and implement software solutions for our customers. Our employees have
pioneered many of the most significant advances that today are considered  industry-standard software
applications across a wide variety of engineering, plant operations and supply chain applications.  Our
services and development staff are recognized experts in delivering value to our customers based on the
practical experience they have gained from supporting IT installations for more than  1,500 process
manufacturers worldwide.

This significant base of chemical engineering expertise, process manufacturing experience and
industry know-how serves as the foundation for the proprietary solution methods, physical property
models and data estimation techniques embedded in our  software  solutions. We continually enhance
our software applications through extensive interaction with our customers, some of which have worked
with our products for more than twenty years. To complement our software expertise, we have
assembled a staff, totaling approximately 230 project engineers as of June 30, 2007, to provide
implementation, advanced process control, real-time optimization, supply chain management and other
consulting services. We believe this consulting team is one of the largest  and most  experienced
collection of experts on process manufacturing operations in the world.

Large and valuable customer base. We view our customer base of more than 1,500  process

manufacturers as an important strategic asset and as evidence of one of the strongest franchises in  the
industry. We count among our customers the world’s 50 largest chemical companies, the  world’s 30
largest petroleum refiners, and 14 of the world’s 15 largest pharmaceutical companies. We also have
numerous leading customers in other vertical markets. In  addition, 14 of the 16 largest engineering and
construction firms that serve the process industries use our design software. These relationships enable
us to identify and develop or acquire solutions that best meet the needs of our customers, and they are
a valuable part of our efforts to penetrate the process industries with new software solutions. We
believe significant opportunities exist for continued penetration of strategic enterprise-wide products,
particularly for our plant operations and supply chain management products. As process manufacturers
increasingly focus on integration and optimization of their operations, we expect many of our existing
customers to be among the first to implement our newly-developed enterprise solutions.

Rapid, high return on investment. We believe that customers purchase our products because our

products provide rapid, demonstrable and significant returns on investment. Because of the large
production volumes and relatively low profit margins typical in many of the process industries, even
small improvements in productivity can generate substantial recurring benefits. First-year savings can

8

exceed the software and implementation costs of our products. Our integrated solutions, whether
applied across a plant, an enterprise or an extended supply chain,  can yield even greater returns. In
addition, our products generate important organizational efficiencies  and operational  improvements, the
dollar benefits of which can be difficult to quantify.

Complete, integrated solution. While some vendors offer  stand-alone products that compete with

one or more of our products, we believe we are the only provider that offers a comprehensive solution
to process manufacturers that addresses key business processes in manufacturing operations across the
enterprise. Our solutions can be used on a stand-alone basis, integrated with one another or  integrated
with third-party applications. Customers can initially choose to implement a point solution  or our
integrated solution, which is scalable as the customer’s needs evolve. The breadth of  our solutions
expands the overall value we can bring to our customers and represent an important source of
competitive differentiation.

Strategy

Our strategy is to build on our position as a market and technology leader by continuing to

enhance and integrate our broad portfolio of engineering, plant operations and supply  chain
management solutions and to deliver new solutions targeted to the specific needs of the  vertical
industries we serve. To implement this strategy  we  intend  to:

Build on our technology leadership by delivering an integrated suite of scalable  vertical industry

solutions. We intend to build on our proven technology leadership and installed base by  delivering
integrated solutions targeted at specific vertical segments, which provide a broader set of capabilities  and
deliver a  higher  value proposition to existing and prospective customers. With  the October  2004  release
of aspenONE, we  became the first software vendor to provide an integrated suite of engineering, plant
operations and supply chain management software applications for process manufacturing. The
aspenONE framework provides an integration layer that enables our products to  work together to
provide our customers with access to critical operational information more immediately. As a result,
aspenONE has been adopted by a number of leading chemical and energy companies.

Maintain and strengthen our market leadership for stand-alone solutions. We intend to maintain and

strengthen our competitive position for stand-alone applications in engineering,  plant  operations and
supply chain management by continuing to develop and  enhance our  existing offerings to respond to
competitive pressures and our customers’ needs. During fiscal 2006  we delivered substantial new
functionality in each major product area, and further enhancements are planned for forthcoming
product releases.

Invest selectively in new, high-value solutions. We intend to invest in a few specific  modules that we

believe will unlock new sources of value for customers in selected segments of the  process industries.
These investments are intended to accelerate the development and commercialization of highly  focused
modules that incorporate technology from our engineering, plant operations and supply  chain
management products. These applications include:

• aspenONE Planning, Scheduling & Blending: an integrated solution that improves planning and

scheduling production at refineries;

• aspenONE Inventory Management & Operations Scheduling: a solution that helps petroleum

companies manage the operational risk and financial exposure that result from lack of visibility
into current and projected inventories, and allowing them to make the best buy vs. make vs. trade
operational decisions.

• aspenONE Ethylene Scheduling: an integrated solution that optimizes the business process of

procuring feedstocks and scheduling ethylene plants.

9

Leverage strategic alliance relationships. Alliances are an important part of our strategy to help us

accelerate the time it takes to bring products to market and provide us with additional resources  to
implement enterprise solutions. We have alliances with Accenture, Intergraph,  Microsoft  and
Schlumberger. We intend to continue to work with a select number of strategic alliances that will help
us increase our sales and implementation effectiveness.

Products: Software and Services

We  provide software and services that enable our customers to optimize the profitability of  their

manufacturing operations. Our software is based upon proprietary empirical  models of chemical
manufacturing processes and the equipment used in those processes that  provide highly accurate
representations of the chemical and physical properties of a broad range of materials typically
encountered in the process industries. These models and the associated knowledge captured in  the
supporting IT systems provide real-time, intelligent decision  support across  the entire process
manufacturing enterprise.

Our solutions are focused on three primary business areas: engineering, plant operations,  and
supply chain management, and are delivered both as  stand-alone solutions and as  part of the  integrated
aspenONE product suite. The aspenONE framework provides an integration  layer  that enables  our
engineering, plant operations and supply chain products to be integrated in modular fashion so that
data can be shared among  them and additional modules can be added  as  the customer’s  requirements
evolve. The result is enterprise-wide access to real-time, model-based information that enables
manufacturers to forecast or simulate the economic impact of potential actions and  make  better, faster
and more profitable operating decisions.

Engineering.

In the process industries, maximizing profit begins with optimal design. Process

manufacturers must be able to address a variety of challenging questions  relating to strategic planning,
collaborative engineering and debottlenecking and process improvement—from where  they should
locate their facilities, to how they can make their products at the lowest cost,  to  what is the best  way to
operate for maximum efficiency. To address these issues, they must improve asset  optimization  to
enable faster, better execution of complex projects. Our engineering solutions help  companies maximize
their return on plant assets and enable collaboration with engineers on common models and  projects.

Our engineering solutions are used on the process engineer’s desktop to design  and  improve plants

and processes. Our customers use our engineering software and services during both the  design and
ongoing operation of their facilities to model and improve the way they develop and deploy
manufacturing assets. Our products enable our customers to  improve their  return on capital, improve
physical plant operating performance and bring new products to market more quickly. See below for a
listing of our principal engineering products.

Our engineering tools are based on an open environment and are implemented  on Microsoft’s

operating systems. Implementation of our engineering products does  not typically require substantial
consulting services, although services may be provided for customized model designs and process
synthesis.

Plant operations. Our plant operations products focus on optimizing companies’ day-to-day
process industry activities, enabling them to make better, more profitable decisions and improve plant
performance. The process industries’ typical production cycle offers many opportunities for optimizing
profits. Process manufacturers must be able to address  a wide  range of issues driving execution
efficiency and cost, from selecting the right feedstock and raw materials, to production scheduling, to
identifying the right balance among customer satisfaction, costs and inventory. Our plant operations
products support the execution of the optimal operating plan in real time. Our plant operations
solutions include desktop applications, IT infrastructure and services that enable companies to model,
manage and control their plants more efficiently, helping them to make better-informed, more

10

profitable decisions. These solutions help companies make decisions that can reduce  fixed  and  variable
costs in the plant, improve product yields, procure the right raw materials and evaluate opportunities
for cost savings and efficiencies in their operations. See below for  a listing of our  principal plant
operations products.

Supply chain management. Our supply chain management products enable companies to reduce

inventory and increase asset efficiency by giving them the tools to optimize their supply chain decisions
from choosing the right raw materials to delivering finished product in the most cost-effective manner.
The ever-changing nature of the process industries means new profit opportunities can appear at  any
time. To identify and seize these opportunities, process  manufacturers  must be able to increase their
access to data and information across the value chain, optimize planning and collaborate across the
value chain, and detect and exploit supply chain opportunities. Our supply chain management solutions
include desktop applications, IT infrastructure and services that enable manufacturers to operate their
plants and supply chains more efficiently, from customer demand through manufacturing to delivery of
the finished product. These solutions help companies to reduce inventory carrying costs,  respond more
quickly to changes in market conditions and improve customer service. See below for a listing of our
principal supply chain products.

Our engineering software products represented approximately 65% of our software license revenue

in each of fiscal 2006 and fiscal 2007, while our plant operations and supply chain management
solutions represented approximately 35% of our software license revenue in each  of fiscal 2006 and
fiscal 2007.

Our software products can be linked with a customer’s existing ERP products and DCS  to  further

improve a customer’s ability to gather, analyze and use the resulting information across the process
manufacturing lifecycle. Our products provide decision support  tools that use  real-time plant
information to determine the best economic alternative for the enterprise. These decisions cannot be
adequately made by simply analyzing historical data from ERP systems or from disparate software
applications that are not integrated. By modeling future operational behavior, using consistent data and
models of their facilities, our products provide our customers with a path to  capturing  economic value
and materially improving profitability.

Professional Services

We  offer professional services to provide our customers with  complete solutions. These  services

include implementation and configuration services, consulting services and advanced  modeling  and
design services. Our implementation and configuration services  are primarily associated  with the
deployment of our plant operations and supply chain management solutions. Customers have
historically used our engineering and innovation solutions without  implementation assistance.

Customers who obtain consulting services from us typically engage us to provide such services over
periods of up to 24 months. We generally charge customers for consulting services, ranging from supply
chain to on-site advanced process control and optimization services, on a  fixed-price  basis or
time-and-materials basis.

As of June 30, 2007, we employed a staff of approximately 230 project engineers to provide
consulting services to our customers. We believe this large  team of experienced and knowledgeable
project engineers provides an important source of competitive  differentiation. We primarily  hire as
project engineers individuals who have obtained doctoral or  master’s degrees in  chemical  engineering
or a related discipline or who have significant relevant industry experience. Our employees include
experts in fields such as thermophysical properties, distillation,  adsorption  processes,  polymer processes,
industrial reactor modeling, the identification of empirical models for process control or analysis, large-
scale optimization, supply distribution systems modeling and scheduling  methods.

Historically, most licensees of our planning and scheduling products and  a limited  number of
licensees of our process information management and supply chain management systems have obtained
implementation consulting services from third-party vendors. Our strategy is to continue  to  develop and
expand relationships with third-party consultants in order to provide a secondary channel of  consulting
services.

Strategic Alliances

We  have established strategic alliances with a  few  select companies that  offer  a complementary set
of technologies, services and industry expertise that help  us commercialize and accelerate the adoption
of our integrated solutions, including aspenONE. These alliances include relationships  with Accenture,
Intergraph, Microsoft and Schlumberger.

In addition to these strategic alliances, we are focused on developing new channel partners,
including resellers, agents and systems integrators, that can help us increase sales in regions and
markets that we do not effectively reach with our direct sales force. Historically, most of our license
sales have been generated through our direct sales force.

Technology and Product Development

Our base of chemical engineering expertise, process manufacturing experience and industry

know-how serves as the foundation for the proprietary solution methods, physical property models and

12

industry-specific business process knowledge embedded in our  software solutions. Our software and
services solutions combine three of our core competencies:

• We support sophisticated empirical models generated  from advanced  mathematical algorithms

developed by our employees. In addition, we support rigorous  models of chemical  manufacturing
processes and the equipment used in those processes. We have used these advanced algorithms
to develop proprietary models that provide highly accurate representations of the  chemical and
physical properties of a broad range of materials typically encountered in the chemicals,
petroleum and other process industries.

• We develop software that models key customer  manufacturing and business processes and

automates the workflow of these processes. This software integrates our broad product  line so
that the data used in manufacturing processes are seamlessly passed between  the applications
used in each step of the business processes.

• We have invested significantly in supply  chain software, which embeds  sophisticated  technology
allowing customers to optimize their extended supply chain activities. In addition, this software
embeds key knowledge about the details of how manufacturing and supply chain operations
function in the process industries.

Our product development activities are currently focused on strengthening the integration between

our applications and adding new capabilities that address specific mission-critical operational business
processes in each industry. We intend to continue to increase the efficiency  of  our research and
development operations through the consolidation of research and development locations  and increased
use of shared components across our applications. In addition, we will continue to enhance our
integrated industry-specific aspenONE solutions by  adding new  functionality, and more standardized
integration with third-party applications.

During fiscal 2005, 2006 and 2007, we incurred research and development costs  of  $47.3 million,

$44.3 million and $42.7 million respectively, which represented 17.6%, 15.1% and 12.5%  of  total
revenues, respectively. As of June 30, 2007, we employed a  product development staff  of  approximately
365 people.

Customers

Our software solutions are installed at the facilities of more than 1,500 customers worldwide.
These customers include process manufacturers and the engineering and  construction  firms that provide
services to them. The following table sets forth a partial selection of our customers from  which we
generated at least $300,000 of revenues in fiscal 2006 or 2007. For fiscal 2007, the percentages of our
license revenue derived from specific vertical markets were approximately as follows:  40% from oil and
gas and petroleum, 30% from chemicals, 20% from engineering and construction design firms and 10%
from other segments of the process industries, the largest of which were  pharmaceutical and consumer
packaged goods.

Sales and Marketing

We  employ a value-based sales approach, offering our customers a comprehensive suite of software

and service products that enhance the efficiency and productivity of their process manufacturing
operations. We have increasingly focused on selling our  products as  a strategic investment  for our
customers and therefore devote an increasing portion of our sales efforts at senior management levels,
including senior decision makers in manufacturing, operations and technology. Our aspenONE solution
strategy supports this value-based approach by broadening the scope of optimization across the entire
spectrum of operations and expanding the use of process models in the operations environment by
linking engineering, plant and business systems to improve our customers’ visibility into their

14

manufacturing operations. We believe our development of new  vertical-specific integrated solutions will
help us to better address the top concerns of senior executives.

Because the complexity and cost of our products often result in extended sales cycles,  we believe

that the development of long-term, consultative relationships with our customers is essential to a
successful selling strategy. To develop these relationships, we focus our worldwide  sales force  on a
defined set of strategic accounts. In North America, we have organized our sales force around  specific
vertical markets. In the rest of the world, the sales force is organized around specific countries or
regions.

In order to market the specific functionality and other complex technical features  of our software

products, each sales account manager and global account manager works with specialized teams of
technical sales engineers and product specialists organized for each sales and marketing effort. Our
technical sales engineers typically have advanced degrees in chemical engineering or related disciplines
and actively consult with a customer’s plant engineers. Product specialists share their detailed
knowledge of the specific features of our software solutions as they  apply to the unique business
processes of different vertical industries.

Our overall sales force, which consists of quota carrying sales account managers, sales services

personnel, business support engineers, partner organization personnel, industry  business  unit
professionals, marketing personnel and support staff, consisted of  approximately 385 people on June 30,
2007.

We  supplement our direct sales efforts with a  variety of  marketing  initiatives, including  public

relations activities, customer relationship programs, internet marketing, campaigns to promote
awareness among industry analysts, user groups and events.

We  also license our software products at  a substantial discount to universities  that  agree to use our
products in teaching and research. We believe that students’ familiarity with  our products will  stimulate
future demand once the students enter the workplace. More than 500 universities  use our software
products in undergraduate instruction.

Competition

Our markets in general are highly competitive and are characterized by  rapid  technological  change.

We  expect the intensity of competition in our  markets to increase in the future as existing competitors
enhance and expand their product and service offerings and as new participants enter the market.
Increased competition may result in price reductions, reduced profitability  and  loss of  market  share. We
cannot assure you that we will be able to compete successfully against existing or  future  competitors.
Some of our customers and companies with which we have strategic relationships also  are, or in the
future may be, competitors of ours.

Many of our current and potential competitors have greater financial, technical, marketing, service

and other resources than we have in a particular market segment or overall. Companies with greater
financial resources may be able to offer lower prices, additional products or services, or other
incentives that we cannot match or offer. These competitors may be in a stronger position to respond
quickly to new technologies and may be able to undertake more extensive marketing campaigns. They
also may adopt more aggressive pricing policies and make more attractive offers to potential customers,
employees and strategic partners.

Many of our competitors have established, and in the future may establish, cooperative

relationships with third parties to improve their product offerings and to increase the availability of
their products to the marketplace. In addition, competitors may make strategic acquisitions to increase
their ability to gain market share or improve the quality or marketability of their products. These

15

cooperative relationships and strategic acquisitions could reduce our market  share, require  us  to  lower
our prices, or both.

Our primary competitors differ between our three principal product areas:

• Our engineering software competes  with products of businesses such as ABB,  Chemstations,
Honeywell, KBC, Shell Global Solutions, Simulation Sciences (a division of Invensys) and
WinSim (formerly ChemShare). As we expand our product  line,  we may face  competition  from
companies that we have not typically competed against in the past, such as Dassault Systemes,
Oracle, SAP and Siemens.

• Our plant operations software competes with products of companies such as ABB, Honeywell,

Invensys, Rockwell and Siemens and components of SAP’s offering.

• Our supply chain management software competes with products of companies such as

Honeywell, i2 Technologies, Manugistics (a subsidiary  of JDA Software Group) and Infor and
components of SAP’s supply chain offering.

In addition, we face competition in all areas of our business from large companies in the process

industries that have internally developed their own proprietary software solutions.

We  believe the key competitive differentiator in  our industry  is the value, or return  on investment,

that our software and services provide. We seek to develop and offer an  integrated  suite of  targeted,
high-value vertical industry solutions that can be implemented with relatively limited service
requirements. We believe this approach provides us with an advantage over many  of our competitors,
which offer software products that are more service-based. The principal competitive factors  in our
industry also include:

• breadth and depth of software offerings;

• domain expertise of sales and service personnel;

• extent of consistent global support;

• performance and reliability;

• price; and

• time to market.

Intellectual Property

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 obtained or applied for patent  protection in  the United States with
respect to some of our intellectual property, but generally do not rely on  patents  as a principal  means
of protecting intellectual property. We have registered or applied to register some  of our significant
trademarks in the United States and in selected 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 codes for products to
customers solely for the purpose of special product customization and have deposited copies of the
source codes for 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.

16

The laws of many countries in which our products are licensed may not protect  our  products and

intellectual property rights to the same extent as the laws of the United States. The laws  of  many
countries in which we license our products protect trademarks solely on the basis of registration.  We
currently possess a limited number of trademark registrations in selected foreign  jurisdictions and  have
applied for certain foreign copyright and patent registrations to protect our  products in  foreign
jurisdictions where we conduct business.

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. We  could  incur substantial  costs  in
protecting and enforcing our intellectual property rights.

Moreover, from time to time third parties may assert patent, trademark, copyright and other
intellectual property rights to technologies that are important to our business. 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 might require that we pay damages or obtain a license of a third party’s proprietary rights
in order to continue licensing our products as currently offered. If such a  license were  required, it
might not be available on terms acceptable to us, or at all.

We  believe that the success of our business depends  more on the quality of our proprietary
software products, technology, processes and know-how than on trademarks, copyrights or patents.
While we consider our intellectual property rights to be valuable, we do  not believe that our
competitive position in the industry is dependent simply on obtaining legal protection for our  software
products and technology. Instead, we believe that the success of our business depends primarily on our
ability to maintain a leadership position in developing our proprietary software products, technology,
information, processes and know-how. Nevertheless, we attempt to protect our  intellectual property
rights with respect to our products and development processes through trademark, copyright  and patent
registrations, both foreign and domestic, whenever appropriate as part of our ongoing research and
development activities.

Employees

As of June 30, 2007, we had a total of 1,291 full-time employees. Of this total, 721 were located in

the United States and 570 were located internationally. None of our employees are represented by a
labor union, except that approximately 11 employees of Hyprotech UK Ltd belong to Prospect Union.
We  have experienced no work stoppages and believe that our employee  relations are satisfactory.

Item 1A. Risk Factors

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,
results of operations or cash flows 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.

Risks Related to Our Business

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:

• demand for our products and services;

• our customers’ purchasing patterns;

• the length of our sales cycle;

• the size of customer orders;

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

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

• seasonal weakness in the first quarter of each fiscal  year (which for us  is  the three months
ending September 30), primarily caused by a seasonal slowdown in business in  some of  our
international markets;

• the timing of our investments in new product development;

• the mix of domestic and international sales;

• our continued ability to sell long-term installments receivable;

• changes in our operating expenses;

• implementation of new quotation and order entry applications and procedures for the

automation of our contracting process; and

• fluctuating economic conditions, particularly as they affect companies in the oil  and gas,

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 expectations of public
market analysts and investors for that quarter.

Since a substantial majority of our expenses are fixed in advance of a particular quarter, we are
not able to adjust our spending quickly enough to compensate for any revenue shortfall in any given
quarter and any such shortfall would likely have a disproportionately adverse effect on our operating
results for that quarter. We expect that the factors listed above  will continue to affect  our operating

18

results for the foreseeable future. Because of the factors  listed above, 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.

Term license renewal negotiations may be difficult and more time consuming than negotiations for
new licenses. Moreover, customers may choose not to renew  term licenses, resulting in  reduced revenue
to us. In addition, customers may wish to negotiate renewals of term licenses on terms  and  conditions
that require us to change the way we recognize revenue under our existing revenue recognition
practices at the time of such renewal with such customers. Any such changes could result in  a material
adverse effect on our results.

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.

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

Because license and implementation 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 our expectations and those of public market analysts and investors. Moreover,  to
the extent that we succeed in licensing our integrated aspenONE product suite  rather than stand-alone
software products, our sales  cycle may lengthen, which could increase the  likelihood  of delays  and
cause the effect of a delay to become more pronounced. Delays in sales could cause  significant
shortfalls in our revenues and operating results for any particular period.

We derive a majority of our total revenues from customers in or serving the oil and gas, chemicals,
petrochemicals and petroleum industries, which are highly cyclical, and our operating results may  suffer if
these industries experience an economic downturn.

We  derive a majority of our total revenues  from companies in or serving  the oil and gas,

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 oil and gas, chemicals, petrochemicals and petroleum industries  are
highly cyclical and highly reactive to the price of oil, as well as general economic conditions.

Adverse changes in the economy and global economic and political uncertainty  have previously

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/supply chain
product suites. If adverse economic conditions occur, we would likely experience reductions, delays and
postponements of customer purchases that will negatively impact our revenue  and  operating results.

In addition, in the past worldwide economic downturns and pricing pressures experienced by oil

and gas, chemical, petrochemical and petroleum companies have led to consolidations and
reorganizations. These downturns, pricing pressures and reorganizations 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.

19

Securities and derivative litigation and government investigations based on our  restatement of  our consolidated
financial statements due to our prior software accounting practices may subject us to substantial damages  and
expenses, may require significant management time and may damage our reputation.

In January 2007, the SEC filed a civil enforcement action in Massachusetts federal  district court

alleging securities fraud and other violations against three of our former executive  officers,  David
McQuillin, Lisa Zappala and Lawrence Evans, arising out of six transactions in 1999 through 2002 that
were reflected in our originally filed consolidated financial statements for fiscal 2000 through 2004,  the
accounting for which we restated in March 2005. We and each of these former executive officers
received ‘‘Wells Notice’’ letters of possible enforcement  proceedings  by the SEC. On the same day  the
SEC complaint was filed, the U.S. Attorney’s Office for the Southern District  of New  York  filed a
criminal complaint against David McQuillin alleging criminal securities fraud violations arising out of
two of those transactions. Mr. McQuillin pled guilty to securities fraud in March 2007 and was
sentenced in October 2007.

On July 31, 2007, we entered into a settlement order with the SEC resolving the Wells  Notice  we

received. Under the settlement order, we agreed to cease and desist from violations of certain
provisions of the federal securities laws, and to comply with certain undertakings. No civil penalty was
assessed by the SEC in connection with that settlement order, and we have not admitted  or denied any
wrongdoing in connection with that settlement order.

We  continue to cooperate with the SEC and U.S. Attorney’s Office. The SEC enforcement action

and the U.S. Attorney’s Office criminal action do  not involve our company or any of our current
officers or directors. We can provide no assurance, however,  that the U.S. Attorney’s  Office, the SEC
or another regulatory agency will not bring an enforcement proceeding against us,  our officers and
employees or additional former officers and employees based on the  consolidated financial statements
that were restated in March 2005.

Any such proceeding would divert the resources of management and could  result in significant
legal expenses and judgments against us for significant damages. In addition,  even  if we are successful
in defending against such an enforcement action, such a proceeding may cause our customers,
employees and investors to lose confidence in our company, which could result in significant costs to us
and adversely affect the market price of our common stock.

We  are required to advance legal fees (subject to undertakings of  repayment if required)  and may
be required to indemnify certain of our current or former directors and officers (including one  or more
of the three former executive officers discussed above) in connection with civil, criminal or regulatory
proceedings or actions, and such indemnification commitments may be costly. Our executive  and
organization liability insurance policies provide only limited  liability  protection relating to such actions
against us and certain of our officers and directors and may not cover the costs of director and officer
indemnification or other liabilities incurred by us. If these policies do not adequately cover expenses
and liabilities relating to any proceeding or lawsuit, or if we are unable to achieve  a favorable
settlement thereof, our financial condition could be materially harmed. Also, increased premiums could
materially harm our financial results in future periods. Our inability to obtain coverage due to
prohibitively expensive premiums would make it more difficult to retain and attract officers and
directors and expose us to potentially self-funding any potential future liabilities ordinarily mitigated by
such liability insurance.

In March 2006, we settled class action litigation, including related derivative claims, arising out of

our restated consolidated financial statements that include the periods referenced in the SEC
enforcement action and the criminal complaint discussed above. Members of the class who opted out of
the settlement (representing 1,457,969 shares of common stock, or less than 1% of the shares putatively
purchased during the class action period) may bring or have brought their own state or federal law
claims against us, which we refer to as opt-out claims.

20

Separate actions have been filed on behalf of the holders of approximately 1.1  million shares who

either opted out of the class action settlement or were not covered by that settlement. The claims in
those actions include claims against us and one or more of our former officers alleging securities and
common law fraud, breach of contract, statutory treble damages, deceptive practices and/or rescissory
damages liability, based on the restated results of one or more fiscal periods included in our restated
consolidated financial statements referenced in the class action. Those actions are:

• Blecker, et al. v. Aspen Technology, Inc.,  et al., filed on June 5, 2006 in the Business Litigation
Session of the Massachusetts Superior Court for Suffolk County and docketed as Civ. A.
No. 06-2357-BLS1 in that court, which is an ‘‘opt out’’ claim asserted  by  persons who received
248,411 shares of our common stock in an acquisition;

• Feldman v. Aspen Technology, Inc., et al., filed on July 17, 2006 in the Business Litigation Session

of the Massachusetts Superior Court for Suffolk County and docketed as Civ. A.
No. 06-3021-BLS2 in that court, which is an ‘‘opt out’’ claim asserted  by  an individual who
received 323,324 shares of our common stock in an acquisition; and

• 380544 Canada, Inc., et al. v. Aspen Technology, Inc., et al., filed on February 15, 2007 in the

federal district court in Manhattan and docketed as Civ. A. No. 1:07-cv-01204-JFK in that court,
which is a claim asserted by persons who purchased 566,665 shares of our common stock in a
private placement.

The damages sought in these actions total more than $20 million, not including claims for treble
damages and attorneys’ fees. If these actions are not dismissed or settled on terms  acceptable  to  us,  we
plan to defend the actions vigorously. We can provide no assurance  as to the outcome  of these  opt-out
claims or the likelihood of the filing of additional opt-out claims, and these claims may result  in
judgments against us for significant damages. Regardless of the outcome, such litigation has  resulted in
the past, and may continue to result in the future, in significant legal expenses  and  may  require
significant attention and resources of management, all of which could result in losses and damages  that
have a material adverse effect on our business.

On December 1, 2004, a derivative action lawsuit captioned Caviness v. Evans, et al., Civil Action
No. 04-12524, referred to as the Derivative Action,  was filed in Massachusetts federal district court as a
related action to the first filed of the putative class actions subsequently consolidated into  the class
action described above. The complaint, as subsequently amended, alleged, among other things, that the
former and current director and officer defendants caused us to issue false and misleading financial
statements, and brought derivative claims for the following: breach of fiduciary  duty for insider trading,
breach of fiduciary duty, abuse of control, gross mismanagement, waste of corporate  assets and unjust
enrichment. On August  18, 2005, the court granted the defendants’  motion  to  dismiss the Derivative
Action for failure of the plaintiff to make a pre-suit demand on the  board  of  directors to take the
actions referenced in the Derivative Action complaint, and the Derivative Action was  dismissed  with
prejudice.

On April 12, 2005, we received a letter on behalf of another purported stockholder, demanding

that the board take actions substantially similar to those referenced in the Derivative Action. On
February 28, 2006, we received a letter on  behalf of the plaintiff  in the Derivative  Action,  demanding
that we take actions referenced in the Derivative Action complaint. The board responded to both of
the foregoing letters that the board has taken the letters under advisement pending further regulatory
investigation developments, which the board continues to monitor and with which we continue to
cooperate. In its responses, the board also requested confirmation of each person’s status as one of our
stockholders and, with respect to the most recent letter, also referred the purported stockholder to the
March 2006 settlement in the class action.

21

A determination that we have failed to comply with our existing consent decree with the Federal  Trade
Commission could have a material adverse effect on our business and financial condition.

In December 2004, we entered into a consent decree with the Federal Trade Commission,  or FTC,

with respect to a civil administrative complaint filed by the FTC in August 2003 alleging  that our
acquisition of Hyprotech in May 2002 was anticompetitive in violation of Section 5 of the Federal
Trade Commission Act and Section 7 of the Clayton Act. In  connection with  the consent decree, we
entered into an agreement with Honeywell International, Inc., which we refer to as the Honeywell
agreement, pursuant to which we transferred our operator training business and our rights to the
intellectual property of various legacy Hyprotech products. In addition, we  transferred our AXSYS
product line to Bentley Systems, Inc.

We  are subject to ongoing compliance  obligations  under the  FTC  consent decree. We have been
responding to requests by the Staff of the FTC for information relating to the Staff’s investigation of
whether we have complied with the consent decree. In addition, the FTC is considering whether to
commence litigation against the Company arising from the Company’s alleged failure to comply with
certain aspects of the decree. If the FTC or a court were to determine that we have not complied with
our obligations under the consent decree, we could be subject to one or more of a variety of penalties,
fines, injunctive relief and other remedies, and associated legal fees and expenses, any of which might
materially limit our ability to operate under our current business plan and might have a material
adverse effect on our operating results and financial condition.

In March 2007, we were served with a complaint and petition to compel arbitration filed  by
Honeywell in New York State Supreme Court. The complaint alleges that we failed to comply with our
obligations to deliver certain technology under the Honeywell agreement referred to above, that we
owe approximately $800,000 to Honeywell under the agreement and that Honeywell is entitled to some
portion of the $1.2 million retained by Honeywell under the holdback provisions of the  agreement, plus
unspecified monetary damages arising from contracts assumed under the agreement.  We believe  the
claims to be without merit and intend to defend the claims vigorously, and to pursue payment  of the
$1.2 million retained under the holdback provisions of the agreement. However, it is possible that the
resolution of the claims may have an adverse impact on our financial position and results of operations.

In preparing our consolidated financial statements, we identified material weaknesses in our internal control
over financial reporting, and our failure to remedy effectively the five material weaknesses  identified as of
June 30, 2007 could result in material misstatements in our financial statements.

Our management is responsible for establishing and maintaining adequate internal control over

our financial reporting, as defined in Rule 13a-15(f) under the Securities Exchange Act. Our
management identified five material weaknesses in our internal control over financial  reporting as of
June 30, 2007. A material weakness is defined as a deficiency, or combination of  deficiencies, in
internal control over financial reporting, such that there is a reasonable possibility that a  material
misstatement of the company’s annual or interim financial statements will not be prevented or detected
on a timely basis.

The material weaknesses identified by management as of June 30, 2007 consisted of:

• Inadequate and ineffective controls  over the periodic financial  close process;

• Inadequate and ineffective controls  over the accounting  for transfers of customer installment and

accounts receivables under receivable sale facilities;

• Inadequate and ineffective controls  over income tax  accounting  and  disclosure;

• Inadequate and ineffective controls  over the recognition of revenue; and

• Ineffective and inadequate controls  over the accounts receivable  function

22

As a result of these material weaknesses, our management concluded as of June 30, 2007 that our
internal control over financial reporting was not effective based on criteria set forth  by the Committee
of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework.

We are implementing remedial measures designed to address these material weaknesses.  If these

remedial measures are  insufficient to address these material weaknesses, or if  additional material
weaknesses or significant deficiencies in our internal control are discovered or occur in  the future,  we
may fail to meet our future reporting obligations on a timely basis, our consolidated financial
statements may contain material misstatements, we could be required to restate our  prior period
financial results, our operating results may be harmed, we may be subject to class action  litigation, and
if we regain listing on a public exchange, our common stock could be delisted from that exchange.  For
example, material weaknesses that remain unremediated could result in material post-closing
adjustments in future financial statements. Any failure to address the identified material weaknesses  or
any additional material weaknesses in our internal control could also adversely affect the results  of the
periodic management evaluations regarding the effectiveness of our internal control over financial
reporting that are required to be included in our annual reports on Form 10-K. Internal control
deficiencies could also cause investors to lose confidence in our reported financial information. We can
give no assurance that the measures we have taken to date or any future  measures  will remediate the
material weaknesses identified or that any additional material weaknesses or  additional  restatements  of
financial results will not arise in the future due to a failure to implement and maintain adequate
internal control over financial reporting or circumvention of these controls. In addition, even if  we are
successful in strengthening our controls and procedures, those controls and procedures may not be
adequate to prevent or identify irregularities or errors or to facilitate the fair presentation of our
consolidated financial statements.

If we do not become current in our SEC filings, or if in the future we are not current  in our SEC filings, we
will face several adverse consequences.

If we are unable to become or remain current in our financial filings, investors in our securities

will not have information regarding our business and financial condition with which to make decisions
regarding investment in our securities. In addition, we are and would not be able to have a  registration
statement under the Securities Act of 1933, covering a public offering of securities, declared effective
by the SEC, and we will not be able to make offerings pursuant to existing registration statements or
pursuant to certain ‘‘private placement’’ rules of the SEC under Regulation D  to any purchasers not
qualifying as ‘‘accredited investors.’’ We also are and would not be eligible to use a ‘‘short form’’
registration statement on Form S-3 for a period of 12 months after the time we  become current in our
filings. These restrictions may impair our ability to raise funds should we  desire to do so and  may
adversely affect our financial condition. Also, if we are unable to become or remain current in our
filings, and if we are not able to obtain waivers under our financing arrangements, it might become
necessary to repay certain  borrowings.

Our common stock has been delisted from The NASDAQ Stock Market and transferred to the Pink  Sheets
electronic quotation service, which may, among other things, reduce the price of  our common stock and the
levels of liquidity available to our stockholders.

As a result of our inability to timely file this Form 10-K, Nasdaq issued a Staff Determination  to
us that, in the absence of a request for a hearing, would have resulted in suspension of trading of our
common stock, and filing of a Form 25-NSE with the SEC to remove our securities  from listing  and
registration on The NASDAQ  Stock Market. Nasdaq subsequently  issued an  Additional Staff
Determination citing our inability to timely file our Form 10-Q for the quarterly period ended
September 30, 2007 as an additional basis for delisting our securities. An oral hearing was held at our
request on November 15, 2007. At the hearing, we requested an extension of time to cure our SEC

23

filing deficiency. The Nasdaq Listing Qualifications Panel, or the Panel, determined on January 7, 2008
to grant our request for continued listing, subject to certain conditions, including filing this  Form 10-K
and our Form 10-Q for the quarterly period ended September 30, 2007, by  January 18,  2008. On
January 28, 2008, the Panel granted our request  for  an extension for continued listing  on The
NASDAQ Global Market through February 8,  2008. On  February 14, 2008,  we received a letter
advising us that the Nasdaq Listing Qualifications Panel had determined to delist our shares from The
NASDAQ Stock Market, and trading of our shares was suspended  effective at the  open of business on
February 19, 2008. Our common stock has been quoted on  the Pink Sheets LLC electronic  quotation
service beginning on February 19, 2008.

There is no assurance that we will regain listing of our common stock on a public exchange. If we

regain listing and thereafter fail to keep current in our SEC filings or to comply with the applicable
continued listing requirements, our common stock might be delisted  and subsequently would trade on
the Pink Sheets electronic quotation service,  or the Pink Sheets. The trading of our common stock  in
the Pink Sheets may reduce the price of  our common stock and the levels of liquidity available to our
stockholders. In addition, the trading of our common stock in the Pink Sheets would materially
adversely affect our access to the capital markets, and the limited liquidity and  potentially reduced
price of our common stock could materially adversely affect our ability to raise capital through
alternative financing sources on terms acceptable to us or at all. Stocks that trade in the Pink  Sheets
are no longer eligible for margin loans, and a company trading in  the Pink Sheets  cannot avail itself of
federal preemption of state securities or ‘‘blue sky’’ laws, which adds substantial compliance costs to
securities issuances, including pursuant to employee option plans, stock  purchase plans  and private or
public offerings of securities. If we are delisted in the future and transferred to the Pink Sheets, there
may also be other negative implications, including the potential loss of confidence by suppliers,
customers and employees, the loss of institutional investor  interest in our company.

Claims and litigation based on our restatement of our consolidated financial statements due to our prior
accounting for stock-based compensation may require that we incur substantial  additional  expenses and
expend significant additional management time.

In connection with the preparation of our consolidated financial statements for fiscal 2006, a
subcommittee of independent members of the board of directors determined that certain stock  option
grants during fiscal 1995 through 2004 were accounted for incorrectly and concluded that stock-based
compensation associated with certain grants was misstated in fiscal 1995 through 2005 and the nine
months ended March 31, 2006. As a result of these errors, some of our employees  realized  nonqualified
deferred compensation for purposes of Section 409A of the Internal Revenue Code  and, therefore
became subject to an excise tax on the value of the options in the year in which they vest. We may be
named as a defendant in securities litigation or derivative lawsuits by current or former stockholders
based on the restated consolidated financial statements. Further, we may be subject  to  claims relating
to adverse tax consequences with respect to stock options covered by the restatement. Defending
against potential claims will likely require significant attention and resources of  management and could
result in significant legal expenses.

On September 27, 2006, a derivative action lawsuit  was filed in  Massachusetts Superior Court
captioned Rapine v. McArdle, et al., Civil Action No. 06-3455. The complaint alleged, among other
things, that the former and current director and officer defendants ‘‘authorized, modified, or failed to
halt backdating of stock options in dereliction of their fiduciary duties to the Company as directors and
officers.’’ On October 16, 2006, defendants removed  the action to Massachusetts federal district court
and moved to dismiss the complaint. On October 30, 2006, the purported stockholder  plaintiff filed  an
amended complaint, asserting derivative claims for breach of fiduciary duty; unjust enrichment; insider
trading; violations of Sections 10(b), 14 and 20(a) of the Securities Exchange Act of 1934; and

24

corporate waste. In October 2007, the court closed this action and  consolidated the action with the
Risberg case referenced below, which was subsequently dismissed.

In February 2007, a derivative action lawsuit  was  filed in Massachusetts  federal district court
captioned Risberg v. McArdle et al., 07-CV-10354. The plaintiff purports to bring a  derivative  action on
our behalf alleging, among other things, that several former and current directors and officer
defendants authorized, were aware of, or received ‘‘backdated’’ stock options. The complaint  asserts
claims for breach of fiduciary duty; unjust enrichment; violations of Sections  10(b), 14  and 20(a) of the
Securities Exchange Act of 1934; corporate waste; and breach  of  contract. In January 2008, the court
granted defendants’ motion to dismiss this action for failure of the plaintiff  to  make  a pre-suit demand
on our board of directors, and judgment on the order of dismissal was entered in favor of all
defendants.

Our international operations are complex and if we fail to manage those operations effectively, the growth of
our business would be limited and our operating results would be adversely affected.

As of June 30, 2007, we had 29 offices in 22 countries. We sell our products primarily through a
direct sales force located throughout the world. In the event that we are unable to adequately staff and
maintain our foreign operations, we could face difficulties managing our international operations. We
also rely, to a lesser extent, on distributors and resellers to sell  our  products and market our  services
internationally, and our inability to manage and maintain those relationships  would limit our ability to
generate revenue outside the United States. The complexities of our operations also  require us to make
significant expenditures to ensure that our operations are compliant with regulatory requirements in
numerous foreign jurisdictions. To the extent we are unable to manage the  various risks associated with
our complex international operations effectively, the growth and profitability of our  business  may be
adversely affected.

Our business may suffer if we fail to address challenges associated with transacting business internationally.

Customers outside the United States accounted for approximately  57% and 53% of our total
revenues in fiscal 2006 and 2007, respectively. 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;

• less effective protection of intellectual property;

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

• difficulties and delays in negotiating  software licenses compliant  with accounting  revenue

recognition requirements in the United States;

• difficulties in collecting trade accounts receivable in other countries; and

• adverse tax consequences.

In addition, 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,  economic
hedging of a significant portion of installment contracts denominated in foreign currencies. Any
hedging policies implemented by us may not be successful, and the cost of these hedging techniques
may have a significant negative impact on our operating results.

25

Competition from software offered by current competitors and new market entrants, as  well as from internally
developed solutions, could adversely affect our ability to sell our software products and related services and
could result in pressure to price our products in a manner that reduces our margins.

Our markets in general are highly competitive:

• Our engineering software competes  with products of businesses such as ABB,  Chemstations,
Honeywell, KBC, Shell Global Solutions, Simulation Sciences (a division of Invensys) and
WinSim (formerly ChemShare).

• Our plant operations software competes with products of companies such as ABB, Honeywell,

Invensys, Rockwell and Siemens and components of SAP’s product offerings.

• Our supply chain management software competes with products of companies such as

Honeywell, i2 Technologies, Manugistics (a subsidiary  of JDA Software Group) and Infor and
components of SAP’s supply chain offering.

As we expand our engineering solutions into other markets we may  face competition from
companies that we have not typically competed against in the past or competition from companies in
areas where we have not competed in the past, such as Dassault Systems, Oracle,  SAP and Siemens.
We  also face competition in all areas  of  our  business  from large companies  in the process industries
that have internally developed their own proprietary software solutions.

Many of our current and potential competitors have greater financial, technical, marketing, service

and other resources than we have. As a result, these companies may be able to offer lower prices,
additional products or services, or other incentives that we cannot match or offer. These competitors
may be in a stronger position to respond more quickly to new technologies and may be able to
undertake more extensive marketing campaigns. They also may adopt more aggressive pricing policies
and make more attractive offers to potential customers, employees and strategic  partners.  In addition,
many of our 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 in the marketplace. Competitors with greater financial resources may make strategic
acquisitions to increase their ability to gain market share or improve the quality or marketability of
their products.

Competition could seriously impede our ability to sell additional software products and related

services on terms favorable to us. Businesses may continue to enhance their internally  developed
solutions, rather than investing in commercial software such as ours. Our current and potential
commercial competitors may develop and market new technologies that  render our existing or future
products obsolete, unmarketable or less competitive. In addition, if these competitors develop products
with similar or superior functionality to our products, we may need to decrease the prices  for our
products in order to remain competitive. If we are unable to maintain  our  current pricing  due to
competitive pressures, our margins will be reduced and our  operating results will  be  negatively affected.
We  cannot assure you that we will be  able to compete  successfully  against  current or future competitors
or that competitive pressures will not materially adversely affect our business, financial condition and
operating results.

If we fail to develop new software products or enhance existing products and services, we will be unable to
implement our product strategy successfully and 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 increasingly sophisticated

26

customer requirements and the technological developments of our competitors. Our business and
operating results could suffer if we cannot successfully respond to the technological advances of
competitors or if our new products or product enhancements and services do not achieve market
acceptance.

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  markets. We are
implementing a product strategy that unifies our software solutions under the aspenONE brand with
differentiated aspenONE vertical solutions targeted at specific  process industry  segments. We cannot
assure you that our product strategy will result in products that will meet  market  needs  and  achieve
significant market acceptance.

Defects or errors in our software products could harm our reputation, impair our ability to  sell our products
and result in significant costs to us.

Our software products are complex and may contain undetected defects or errors. We have not

suffered significant harm from any defects or errors to date, but we have from time to time found
defects in our products and we may discover additional defects in the future.  We may not  be  able  to
detect and correct defects or errors before releasing products. Consequently, we or our customers may
discover defects or errors after our products have been implemented. We have in the past issued, and
may in the future need to issue, corrective releases of our products to remedy  defects  or errors. The
occurrence of any defects or errors could result in:

• lost or delayed market acceptance  and sales of our products;

• delays in payment to us by customers;

• product returns;

• injury to our reputation;

• diversion of our resources;

• legal claims, including product liability claims, against us;

• increased service and warranty expenses or financial  concessions; and

• increased insurance costs.

Defects and errors in our software products could result in an increase in service and warranty

costs or claims for substantial damages against us.

We may  be subject to significant expenses and damages because of liability claims  related to our products and
services.

We  may be subject to significant expenses and  damages because of liability claims related to our
products and services. The sale and implementation of certain of our software products and services,
particularly in the areas of advanced process control, supply chain and optimization, entail the risk of
product liability claims and associated damages. Our software products and services are often
integrated with our customers’ networks and software applications and are used in the design,
operation and management of manufacturing and supply chain processes at large facilities, often for
mission critical applications. Any errors, defects, performance problems or other failure of our software
could result in significant liability to us for damages or for violations of environmental, safety and other
laws and regulations. We are currently  defending claims that certain of  our software products and
implementation services have failed to meet customer expectations. On May 11, 2007, one of the claims
resulted in a $1.4 million arbitration award against us. We are defending other claims in excess  of
$5 million, primarily consisting of a customer claim, as well as other general commercial claims. In

27

addition, our software products and implementation services could continue to give rise to warranty and
other claims. We currently are unable to determine  whether resolution  of any of these matters will  have
a material adverse impact on our financial position, cash flows or  results  of operations, or, in  many
cases, reasonably estimate the amount of the loss, if any,  that may result from the resolution of these
matters.

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 not be effective as a result of federal, foreign, state or  local laws  or ordinances or
unfavorable judicial decisions. A substantial product liability judgment  against us could materially and
adversely harm our operating results and financial condition. Even if our  software is not at fault,  a
product liability claim brought against us could be time consuming,  costly to defend and harmful  to  our
operations. In addition, although we carry general liability insurance, our current insurance coverage
may be insufficient to protect us from all liability that may be imposed under these types of claims.

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
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.  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.

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. Under these fixed-price
engagements, we bear the risk of cost overruns and inflation, 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.

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.

28

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.

Third-party claims that we infringe upon the intellectual property rights of others may be costly to defend or
settle and could damage our business.

We  cannot be certain that our software and  services do  not infringe issued patents,  copyrights,

trademarks or other intellectual property rights of third  parties. Litigation regarding intellectual
property rights is common in the software industry, and we may  be  subject to legal proceedings and
claims from time to time, including claims of alleged infringement of intellectual property  rights of
third parties by us or our licensees concerning their use of our software products and integration
technologies and services. Although we believe that our intellectual property rights  are sufficient  to
allow us to market our software without incurring liability to third parties, third parties may bring
claims of infringement against us. Because our software is integrated with our  customers’  networks and
business processes, as well as other software applications, third parties  may bring claims of infringement
against us, as well as our customers and other software suppliers,  if the cause of the  alleged
infringement cannot easily be determined. Such claims may be with or without merit.

Claims of alleged infringement may have a material adverse effect on our business and may
discourage potential customers from doing business with us on acceptable terms, if at all.  Defending
against claims of infringement may be time-consuming and may result  in substantial costs and diversion
of resources, including our management’s attention to our business. Furthermore, a party making  an
infringement claim could secure a judgment that requires us to pay substantial damages.  A judgment
could also include an injunction or other court order that could prevent us from selling our software or
require that we re-engineer some or all of our products. Claims of intellectual  property  infringement
also might require us to enter costly royalty or license agreements. We may be unable,  however, to
obtain royalty or license agreements on terms acceptable to us or at all. Our business, operating results
and financial condition could be harmed significantly if any of these events occurred, and the price  of
our common stock could be adversely affected. Furthermore, former employers of our current and
future employees may assert that our employees have improperly disclosed confidential or proprietary
information to us. In addition, we have agreed, and may agree in the future, to indemnify certain of
our customers against claims that our software infringes upon the intellectual property rights  of others.
Although we carry general liability insurance, our current insurance coverage may not apply to, and
likely would not protect us from, liability that may be imposed under any of the types of claims
described above.

Because some of our software products incorporate technology licensed from, or provided by, third parties, the
loss of our right to use that third-party technology or defects in that technology could harm our business.

Some of our software products contain technology that is licensed from, or provided by, third
parties. Any significant interruption in the supply or support of any such third-party software could
adversely affect our sales, unless and until we can replace the functionality provided by the third-party
software. Because some of our software incorporates software developed and maintained by third
parties, we depend on these third parties to deliver and support reliable products, enhance our current
software, develop new software on a timely and cost-effective basis and respond to emerging industry
standards and other technological changes. In other instances, we provide third-party software with our
current software, and we depend on these third parties to deliver reliable products, provide underlying

29

product support and respond to emerging industry standards and other technological changes. The
failure of these third parties to meet these criteria could harm our business.

New accounting standards or interpretations of existing accounting standards could adversely affect our
operating results.

Generally accepted accounting principles, or GAAP, in the United States  are subject to

interpretation by the Financial Accounting Standards Board, the American Institute of Certified  Public
Accountants, the SEC and various bodies  formed to promulgate and interpret appropriate accounting
principles. A change in these principles or interpretations could have a significant effect on our
reported financial results and could affect the reporting of transactions completed before the
announcement of a change.

For example, we recognize software license revenue in accordance with SOP  No. 97-2, as amended
by SOP No. 98-4 and SOP No. 98-9, and in accordance with SOP No. 81-1. The accounting profession
may continue to discuss certain  provisions of relevant accounting literature with the objective of
providing additional guidance on potential interpretations related to software revenue recognition and
‘‘multiple element arrangements’’ in which a single contract includes a software license,  a maintenance
services agreement and/or other ‘‘elements’’ that are bundled together  in  a total offering to the
customer. These discussions and the issuance of interpretations, once  finalized, could  lead to
unanticipated changes in our current revenue accounting practices, which could change  the timing of
revenue recognition.

If we are not successful in attracting, integrating and retaining highly qualified personnel,  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
software market depends in large part upon our ability to attract, integrate and retain highly  qualified
managerial, sales, technical and accounting personnel. Competition for qualified  personnel in  the
software industry is intense. 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. Moreover, we have recently hired a significant number and percentage of the
personnel in key areas of our operations, such as accounting and finance. Our  management  will need to
devote significant attention and resources to strengthen relationships among these personnel, and our
ability to grow our business will be impaired if these personnel are not able to work  together
effectively. Our future success will depend in large part on our ability  to  attract,  integrate and retain a
sufficient number of highly qualified personnel, and there can be no assurance that  we will  be  able to
do so.

If we are unable to develop or maintain strategic alliance relationships, our revenue growth, operating results,
financial condition or cash flows may be materially and adversely affected.

An element of our growth strategy is to establish strategic alliances with selected third-party

resellers, agents and systems integrators, which we refer to collectively as resellers, that market, sell and
integrate our products and services. It is possible that our existing relationships with resellers might be
terminated by us or the resellers, or that we will not adequately train, and enter into agreements with,
a sufficient number of qualified resellers, or that potential resellers may focus their efforts on
marketing competing products to the process industries.

In addition, the cessation or termination of certain relationships, by us or a reseller, may subject us

to material liability and/or expense. This material liability and/or expense includes potential payments
due upon the termination or cessation of the relationship by us or a reseller, costs related to the
establishment of a direct sales presence or development of a new agent in the territory. No such events

30

of termination or cessation have occurred. We are not able to reasonably estimate the amount of any
such liability and/or expense if such an event were to occur, given the  range of factors that could affect
the ultimate determination of our liability, including possible claims related to the validity of the
arrangements or contract terms. Actual payments could be in the range of zero  to  $30 million. If any of
the foregoing were to occur, our future revenue growth could be limited or we may be subject to
litigation and liability claims such that our operating results, cash  flows and  financial condition could be
materially and adversely affected.

In addition, if our resellers fail to implement our solutions for our customers properly, our

reputation could be harmed and we could be subject to claims by our customers. We intend to continue
to establish business relationships with resellers to accelerate the  development and marketing  of our
products and services. To the extent that we are unsuccessful in maintaining our existing relationships
and developing new relationships, our operating results and financial condition could be materially and
adversely affected.

Risks Related to Our Common Stock

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.

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

Our ability to raise capital in the future may be limited, and our failure to raise capital  when needed could
prevent us from executing our business plan.

We  expect that our current cash balances,  future  cash flows from our operations, and  continued
ability to sell installment receivable contracts will be sufficient to meet our  anticipated cash needs for at
least the next twelve months. We may need to obtain additional financing thereafter or earlier,
however, 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, fewer sales of
installment contracts, unanticipated expenses or other unforeseen difficulties.

Our ability to obtain additional financing will depend on a number of factors, including  market

conditions, our operating performance, the quality of our installment contracts, the  reaction of the
capital and credit markets to our financial restatement with the inclusion of  secured  borrowings, and
investor interest. These factors may make the timing, amount, terms and conditions of any financing
unattractive. 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 additional capital raised through the sale of equity or convertible debt securities may dilute
the existing shareholder percentage ownership of our common stock. Furthermore, any new securities
we issue could have rights, preferences and privileges superior to our common stock. Capital raised
through debt financings could require us to make periodic interest payments and could impose
potentially restrictive covenants on the conduct of our business.

31

Our corporate documents and provisions of Delaware law may prevent a change in control or management
that stockholders may consider desirable.

Section 203 of the Delaware General Corporation Law, our charter and our by-laws contain

provisions that might enable our management to resist a  takeover of our company.

These provisions include:

• limitations on the removal of directors;

• a classified board of directors so that not all members of our board are elected at one time;

• advance notice requirements for stockholder proposals and nominations;

• the inability of stockholders to act by  written consent or to call special meetings;

• the ability of our board of directors to make, alter or repeal our by-laws; and

• the ability of our board of directors to designate the terms  of and  issue new series of preferred

stock without stockholder approval.

These provisions could:

• have the effect of delaying, deferring  or preventing a change in control of our company or a

change in our management that stockholders may consider  favorable  or beneficial;

• discourage proxy contests and make it more difficult for stockholders to elect directors and take

other corporate actions; and

• limit the price that investors might  be  willing  to  pay in the  future for shares of our common

stock.

We  have also adopted a stockholder rights plan that could significantly dilute the  equity interests
of a person seeking to acquire control of our company without the approval of the board of directors.

We are obligated to register for public sale shares of common stock issued  upon  the conversion of our
previously outstanding Series D-1 preferred stock, and sales of  those shares  may  result in a decrease  in the
price of our common stock.

Private equity funds managed by Advent International  Corporation have the  right to require that
we register under the Securities Act the shares of common stock that were issued upon the conversion
of our previously outstanding Series D-1 preferred stock and upon the exercise of certain previously
outstanding warrants. In May 2006, we received a demand letter from such funds requesting the
registration of all of the shares of common stock covered by those registration rights, for sale in an
underwritten public offering. Pursuant to this request, in April 2007 we filed a registration statement
for a public offering of 18,000,000 shares of common stock held by such funds. The  registration
statement also covered 2,700,000 shares that would be subject to an option to be granted to the
underwriters by such funds solely to cover overallotments. This registration statement remains on file
with the SEC. Any sale of common stock into the public market pursuant to the pending registration
statement could cause a decline in the trading price of our common stock.

Item 2. Properties

In May 2007, we entered into a lease agreement with respect to office space in Burlington,

Massachusetts. Commencing September 1, 2007, we moved our principal corporate offices to this
location and occupied 60,177 square feet of space. The initial term of the  lease, commenced with
respect to (a) 31,174 square feet of leased premises on September 1,  2007, (b) an additional 18,947
square feet on October 1, 2007 and (c) an additional 10,056 square feet on January 1, 2008. The initial
term of the lease will expire seven years and four months following the term commencement date for
the third phase of the leased premises. Subject to the terms and conditions of the lease,  we may extend
the term of the lease for two successive terms of five years each at 95%  of  the then current market
rate. Under the lease, we will have total non-cancelable lease obligations of approximately
$10.9 million, and also will pay additional rent for our proportionate share  of operating expenses  and
taxes.

Prior to September 1, 2007, our principal offices occupied approximately 110,000 square feet  of
office space in Cambridge, Massachusetts. The lease of this office  space expires on  September 30, 2012.
As of June 30, 2007, we had agreements that expire through 2012 to sublease approximately 60,000
square feet of this space. We entered into an additional sublease agreement effective from October 1,
2007 through September 30, 2012 for the remaining approximately 50,000 square feet  of  this  space. We
also lease space for our Houston, Texas facilities. This lease encompasses approximately 90,000 square

Item 3. Legal Proceedings

Class Action and Opt-Out Claims

In March 2006, we settled class action litigation, including related derivative  claims, arising  out of

our restated consolidated financial statements that include the periods referenced  in the SEC
enforcement action and the criminal complaint discussed below. Members of the class who opted out of
the settlement (representing 1,457,969 shares of common stock, or less than 1% of the  shares putatively
purchased during the class action period) may bring or have brought their own state or federal law
claims against us, which we refer to as opt-out claims.

Separate actions have been filed on behalf of the holders of approximately 1.1  million shares who

either opted out of the class action settlement or were not covered by that settlement. The claims in
those actions include claims against us and one or more of our former officers alleging securities and
common law fraud, breach of contract, statutory treble damages, deceptive practices and/or rescissory
damages liability, based on the restated results of one or more fiscal periods included in our restated
consolidated financial statements referenced in the class action. Those actions are:

• Blecker,  et al. v. Aspen Technology, Inc.,  et al., filed on June 5, 2006 in the Business Litigation
Session of the Massachusetts Superior Court for Suffolk County and docketed as Civ. A.
No. 06-2357-BLS1 in that court, which is an ‘‘opt out’’ claim asserted by persons who received
248,411 shares of our common stock in an acquisition;

33

• Feldman v. Aspen Technology, Inc., et al., filed on July 17, 2006 in the Business Litigation Session

of the Massachusetts Superior Court for Suffolk County and docketed as Civ. A.
No. 06-3021-BLS2 in that court, which is an ‘‘opt out’’ claim asserted  by  an individual who
received 323,324 shares of our common stock in an acquisition; and

• 380544 Canada, Inc., et al. v. Aspen Technology, Inc., et al., filed on February 15, 2007 in the

federal district court in Manhattan and docketed as Civ. A. No. 1:07-cv-01204-JFK in that court,
which is a claim asserted by persons who purchased 566,665 shares of our common stock in a
private placement.

The damages sought in these actions total more than $20 million, not including claims for treble
damages and attorneys’ fees. If these actions are not dismissed or settled on terms  acceptable  to  us,  we
plan to defend the actions vigorously.

SEC Action and U.S. Attorney’s Office Criminal Complaint

In January 2007, the SEC filed a civil enforcement action in Massachusetts federal  district court

alleging securities fraud and other violations against three of our former executive  officers,  David
McQuillin, Lisa Zappala and Lawrence Evans, arising out of six transactions in 1999 through 2002  that
were reflected in our originally filed consolidated financial statements for fiscal 2000 through 2004, the
accounting for which we restated in March 2005. We and each of these former executive officers
received ‘‘Wells Notice’’ letters of possible enforcement  proceedings  by the SEC. On the same day the
SEC complaint was filed, the U.S. Attorney’s Office for the Southern District  of New  York  filed a
criminal complaint against David McQuillin alleging criminal securities fraud violations arising out of
two of those transactions. Mr. McQuillin pled guilty in March 2007 and was sentenced in October 2007.

On July 31, 2007, we entered into a settlement order with the SEC resolving the Wells  Notice we

received. Under the settlement order, we agreed to cease and desist from violations of certain
provisions of the federal securities laws, and to comply with certain undertakings. No civil penalty was
assessed by the SEC in connection with that settlement order, and we have not admitted  or denied any
wrongdoing in connection with that settlement order.

The SEC enforcement action and the U.S. Attorney’s Office criminal action do  not  involve  our
company or any of our current officers or directors. We can provide no assurance, however, that the
U.S. Attorney’s Office,  the SEC or another regulatory agency will not bring an  enforcement proceeding
against us, our officers and employees or additional former officers and employees based  on the
consolidated financial statements that were restated in March 2005. We continue to cooperate with the
SEC and the U.S. Attorney’s Office.

Derivative Suits

On December 1, 2004, a derivative action lawsuit captioned Caviness v. Evans, et al., Civil Action
No. 04-12524, referred to as the Derivative Action,  was filed in Massachusetts federal district court as a
related action to the first filed of the putative class actions subsequently consolidated into the class
action described above. The complaint, as subsequently amended, alleged, among other things, that the
former and current director and officer defendants caused us to issue false and misleading financial
statements, and brought derivative claims for the following: breach of fiduciary duty for insider trading,
breach of fiduciary duty, abuse of control, gross mismanagement, waste of corporate assets and unjust
enrichment. On August  18, 2005, the court granted the defendants’  motion  to  dismiss the Derivative
Action for failure of the plaintiff to make a pre-suit demand on the  board  of  directors to take the
actions referenced in the Derivative Action complaint, and the Derivative Action was  dismissed  with
prejudice.

34

On April 12, 2005, we received a letter on behalf of another purported stockholder, demanding

that the board take actions substantially similar to those referenced in the  Derivative Action. On
February 28, 2006, we received a letter on  behalf of the plaintiff  in the Derivative  Action,  demanding
that we take actions referenced in the Derivative Action complaint. The board  responded to both  of
the foregoing letters that the board has taken the letters under advisement pending further regulatory
investigation developments, which the board continues to monitor and with which we continue  to
cooperate. In its responses, the board also requested confirmation  of  each person’s status as  one of our
stockholders and, with respect to the most recent letter, also referred the purported stockholder to  the
March 2006 settlement in the class action.

On September 27, 2006, a derivative action lawsuit  was filed in  Massachusetts Superior Court
captioned Rapine v. McArdle, et al., Civil Action No. 06-3455. The complaint alleged, among other
things, that the former and current director and officer defendants ‘‘authorized, modified, or failed to
halt backdating of stock options in dereliction of their fiduciary duties to the Company  as directors and
officers.’’ On October 16, 2006, defendants removed  the action to Massachusetts federal district court
and moved to dismiss the complaint. On October 30, 2006, the purported  stockholder plaintiff filed an
amended complaint, asserting derivative claims for breach of fiduciary duty; unjust enrichment;  insider
trading; violations of Sections 10(b), 14 and 20(a) of the Securities Exchange Act of 1934; and
corporate waste. In October 2007, the  court closed this action and consolidated the action with the
Risberg case referenced below, which was subsequently dismissed.

In February 2007, a derivative action lawsuit was filed in Massachusetts  federal district court
captioned Risberg v. McArdle et al., 07-CV-10354. The plaintiff purports  to  bring a derivative action on
our behalf alleging, among other things, that several former and current directors and officer
defendants authorized, were aware of, or received ‘‘backdated’’ stock options. The complaint  asserts
claims for breach of fiduciary duty; unjust enrichment; violations of Sections  10(b), 14  and 20(a) of  the
Securities Exchange Act of 1934; corporate waste; and breach  of  contract. In January 2008, the court
granted defendants’ motion to dismiss this action for failure of the plaintiff  to  make  a pre-suit demand
on our board of directors, and judgment on the order of dismissal was entered in favor of all
defendants.

FTC Settlement and Related Honeywell  Litigation

In December 2004, we entered into a consent decree with the FTC with respect to a civil

administrative complaint filed by the FTC in August 2003 alleging that our  acquisition  of  Hyprotech  in
May 2002 was anticompetitive in violation of Section 5 of the Federal Trade Commission  Act and
Section 7 of the Clayton Act. In connection with the consent decree, we entered into an agreement
with Honeywell International, Inc., which we refer to as the Honeywell agreement, pursuant to which
we transferred our operator training business and our rights to the intellectual property of various
legacy Hyprotech products. In addition, we transferred our AXSYS product line to Bentley
Systems, Inc.

We  are subject to ongoing compliance  obligations  under the  FTC  consent decree. We have been
responding to requests by the Staff of the FTC for information relating to the Staff’s investigation of
whether we have complied with the consent decree. In addition, the FTC is considering whether to
commence litigation against the Company arising from the Company’s alleged failure to comply with
certain aspects of the decree. If the FTC or a court were to determine that we have not complied with
our obligations under the consent decree, we could be subject to one or more of a variety of penalties,
fines, injunctive relief and other remedies, and associated legal fees and expenses, any of which might
materially limit our ability to operate under our current business plan and might have a material
adverse effect on our operating results and financial condition.

35

In March 2007, we were served with a complaint and petition to compel arbitration filed  by
Honeywell in New York State Supreme Court. The complaint alleges that we failed to comply with  our
obligations to deliver certain technology under the Honeywell agreement referred to above, that we
owe approximately $800,000 to Honeywell under the agreement and that Honeywell is entitled to some
portion of the $1.2 million retained by Honeywell under the holdback provisions of the  agreement, plus
unspecified monetary damages arising from contracts assumed under the agreement.  We believe  the
claims to be without merit and intend to defend the claims vigorously, and to pursue payment  of the
$1.2 million retained under the holdback provisions of the agreement. However, it is possible that the
resolution of the claims may have an adverse impact on our financial position and results of operations.

Other

We  are currently defending claims that certain  of our software  products and implementation
services have failed to meet customer expectations. On May 11, 2007, one of the  claims  resulted in an
arbitration award against us in the amount of $1.4 million. As of June  30, 2007, we have accrued the
amount of the arbitration award. We are defending other claims in excess  of $5 million, primarily
consisting of a customer claim, as well as other general commercial claims. Although we  believe the
remaining claims to be without merit, and are defending the claims vigorously,  the  results of litigation
and claims cannot be predicted with certainty, and unfavorable resolutions are possible and could,
depending on the amount and timing of any outcome, materially affect our results  of operations,  cash
flows or financial position. In addition, regardless of the outcome, litigation could have an adverse
impact on us because of defense costs, diversion of management resources and other factors.

prohibited from paying any dividends on our stock, with the exception  of  dividends paid in  common
stock or dividends on our preferred stock  paid in cash, provided that we are not in default  under the
loan arrangement. Any future determination relating to our dividend policy will be made at the
discretion of our board of directors and will depend on a number of factors, including our future
earnings, capital requirements, financial condition and future  prospects and  such other factors  as the
board of directors may deem relevant.

described in the ‘‘Explanatory Note’’ immediately preceding  Part  I, Item 1 and Note 17 of the Notes to the Consolidated
Financial Statements. The provision for income taxes in 2003 has been increased by $1.7 million to record tax provision
related to the use of the acquired tax net operating losses that were realized.  The acquired  deferred  tax  asset had a full
valuation allowance and when this valuation allowance was reversed, it should have reduced goodwill. This  benefit  was
incorrectly recognized in earnings. The goodwill impairment recognized in  2003 has  been  correspondingly reduced  by  this
amount and $2.3 million related to tax benefits recognized in 2002, for a total reduction of $4.0  million.

(2) The long-lived asset impairment charges recorded in fiscal 2003 consisted of  $70.2 million  related to goodwill  assets  and

$31.3 million related to acquired intellectual property, internal capital costs and fixed assets. The restructuring charges and
FTC costs recorded in fiscal 2003 consisted of $28.6 million in charges from an October 2002 restructuring plan and
$13.0 million in FTC legal costs related to an FTC challenge of our May 2002 acquisition of Hyprotech.

(3) The restructuring charges and FTC costs recorded in fiscal  2004 consist of $23.5 million in charges from the June 2004

restructuring plan, which is offset by $8.3 million in adjustments from prior restructuring  accruals,  and $4.9  million in  FTC
legal costs.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion of our financial condition and results of operations should  be  read in

conjunction with the consolidated financial statements and related notes thereto contained or
incorporated in this prospectus. This discussion contains forward-looking statements.  Please  see
‘‘Item 1A. Risk Factors’’ for a discussion of certain of the uncertainties,  risks and  assumptions
associated with these statements.

Our fiscal year ends on June 30, and references to a specific fiscal year  are the twelve months

ended June 30 of such year (for example, ‘‘fiscal 2007’’ refers to the year ended June 30, 2007).

Overview

We  are a leading supplier of integrated software and services to the process industries, which
consist of oil and gas, petroleum, chemicals, pharmaceuticals and other industries that manufacture and
produce products from a chemical process. We provide a comprehensive,  integrated suite of software
applications that utilize proprietary empirical models of chemical manufacturing processes  to  improve
plant and process design, economic evaluation, production, production planning and scheduling, and
operational performance, and an array of services designed to optimize the  utilization of these products
by our customers.

The accompanying management’s discussion and analysis gives effect to the  restatement of our
previously issued consolidated financial statements as of  June 30, 2006 and for the years ended June 30,
2006 and 2005 for the matters discussed more fully in Note 17 to the consolidated financial statements
included in Item 8 of this Form 10-K. The restatement also required  the restatement of previously
issued Quarterly Financial Data for the first three quarters of the year ended June 30, 2007 and each
of the quarters in the year ended June 30, 2006 presented herein  and the restatement of Management’s
Discussion and Analysis of Financial Condition and Results of Operations.

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 contingencies;

• accounting for income taxes;

• allowance for doubtful accounts;

• accounting for transfers of financial  assets;

• restructuring accruals; and

• accounting for stock-based compensation.

Revenue Recognition—Software Licenses

We  recognize software license revenue in  accordance with  SOP No. 97-2, as amended by SOP
No. 98-4 and SOP No. 98-9, as well as the various interpretations and clarifications  of  those statements.
When we provide consulting services considered not essential to the functionality of the software,  and
for which vendor-specific objective evidence, or VSOE, of fair value has been established,  we recognize
revenue for the delivered software when the basic criteria of SOP No. 97-2 are met. As our
arrangements generally meet these criteria, revenue is generally  recognized upon delivery. VSOE has
been established for software maintenance services, training and consulting services rates. When we
provide consulting services that are considered essential  to  the functionality of the  software and
involves significant production, modification or customization of the licensed software, we recognize
such revenue and any related software licenses in accordance with SOP No.  81-1, ‘‘Accounting for
Performance of Construction Type and Certain Performance Type Contracts.’’ Four basic criteria must
be satisfied before software license revenue can be recognized:

• persuasive evidence of an arrangement between us 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 reasonably assured.

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, particularly the installments receivable, relating to such
sales. These two criteria are particularly relevant to reseller transactions where, specifically, revenue  is
only recognized upon delivery to the end user, since the determination of whether the fee is fixed or
determinable and whether collection is probable is more difficult. 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—Fixed-Fee Consulting Services

We  recognize revenue associated with fixed-fee  service contracts in accordance with the

proportional performance 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. We have a significant amount of  experience in the
estimation of the total costs to complete a contract and have not typically recorded material losses
related to these estimates. We do not expect the accuracy of our estimates to change  significantly  in the
future. 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 when circumstances dictate that they should
be reevaluated, based upon the expected future operating cash flows of our business or other factors
that trigger an evaluation for potential impairment. The evaluation of the results of any impairment
evaluation is based upon our expected future cash flows. These future cash flow estimates are based on
historical results, adjusted to reflect our best estimate of future markets and operating conditions, and
are updated based on actual operating trends. Historically, actual results have occasionally differed

43

from our estimated future cash flow estimates. In the future, actual results may differ materially from
these estimates, and accordingly cause a full impairment of  our long-lived assets. We had $18.2 million
of long-lived assets at June 30, 2007.

In accordance with SFAS No. 142, ‘‘Goodwill and Other Intangible  Assets,’’ we conduct at least an

annual assessment on December 31 of the carrying value of our goodwill assets, which is based on
either estimates of future income from the reporting units or estimates  of  the market  value of the
reporting 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.
Historically, actual results have occasionally differed from our estimated  future cash flow  estimates. In
the future, 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.
We  had $19.1 million of goodwill recorded at  June 30, 2007.

During fiscal 2004, we recorded $4.2 million in charges related to the impairment  of  certain

long-lived assets and technology related intangible and computer software development assets. We
conducted an annual assessment of the carrying value of our goodwill assets as of December 31, 2006
in accordance with SFAS No. 142. The  assessment indicated  that there was no impairment  of the
carrying value of our goodwill assets as of that date. The timing and size of any future impairment
charges involves the application of management’s judgment and estimates and could result  in the
impairment of all or substantially all of our long-lived assets, intangible assets and goodwill.

Accounting for Contingencies

In accordance with SFAS No. 5, ‘‘Accounting for Contingencies,’’ we accrue loss contingencies if, in

the opinion of management, an adverse outcome is probable and  such outcome can be reasonably
estimated. Significant management judgment is required in assessing the presence of potential loss
contingencies, the probability of an adverse outcome, and the amount of any such estimate of an
adverse outcome. Historically, we have accrued loss contingencies primarily associated with outstanding
litigation and income tax exposures in  foreign tax jurisdictions.

We  also accrue estimated future legal  fees  associated with outstanding litigation for which

management has determined that it is probable that a loss contingency exists. This requires
management to estimate the amount of legal fees that will be incurred in the defense of the litigation.
These estimates are based heavily on our expectations of the scope, length to complete and complexity
of the claims. Historically, as these factors have changed after our  original estimates, we have adjusted
our estimates accordingly. In the future, additional adjustments may be recorded as the scope, length or
complexity of outstanding litigation changes.

Accounting for Income Taxes

We estimate our income taxes in each of the jurisdictions in  which we operate. This  process

involves estimating our actual current tax liabilities together with the assessment of temporary
differences resulting from differing timing treatment of items, such as reserves and accruals, for tax and
accounting purposes. These differences result in deferred tax assets and liabilities, which are included
within our consolidated balance sheet or disclosed in our footnotes to the financial statements.
Deferred tax assets also result from unused operating loss carryforwards, research and development tax
credit carryforwards and foreign tax credit carryforwards. We 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 establish a valuation allowance. Adjustments to the valuation allowance  are included  in the
tax provision in our statement of operations in the period they become known or estimated.

Significant management judgment is required in determining any valuation allowance recorded

against these deferred tax assets and liabilities. The valuation allowance is based on our estimates of

44

taxable income for jurisdictions in which we operate and the period over which our deferred  tax  assets
may be recoverable. In fiscal 2005, 2006 and 2007, we provided a full valuation allowance for all net
deferred tax assets in the United States and most other tax jurisdictions.

Our U.S. and foreign tax returns are subject to periodic compliance examinations by various local

and national tax authorities through periods defined by  tax codes in  the applicable  jurisdiction. The
years prior to 2004 are closed in the U.S., although the utilization of net operating loss  carryforwards
generated in earlier periods will keep these periods  open  for examinations. Our operating entities in
Canada are subject to audit from year 2000 forward, in the UK from 2006 forward, and other
international subsidiaries from 2002 forward. In connection with  examinations of tax filings, tax
contingencies can arise from differing interpretations of applicable tax laws and regulations relative to
the amount, timing or proper inclusion or exclusion of revenues and expenses in taxable income or loss.
For periods that remain subject to audit,  we have asserted  and unasserted potential assessments that
are subject to final tax settlements.

Our income tax expense includes amounts intended to satisfy income tax assessments, including

interest and penalties, that could result from the examination of our tax returns. Determining the
amount of an estimated obligation, if any, for such contingencies requires a significant  amount  of
judgment. We evaluate such tax contingencies in accordance with  the requirements of SFAS No. 5,
Accounting for Contingencies, based on information currently available, and have  accrued for  income tax
contingencies that meet both the probable and estimable criteria of SFAS No. 5. These estimates  are
updated over time upon receipt of more definitive information from taxing authorities, completion of
tax audits, expiration of statutes of limitation, or upon occurrence of other events. The amounts
ultimately paid upon resolution of such contingencies could be materially different from the  amounts
previously recorded and therefore could have a material impact on our consolidated results of
operations as additional information becomes available. The tax  contingency accrual, including penalties
and interest, is recorded as a component of our accrued expense and other liabilities balance and was
$22.0 million as of June 30, 2007. The ultimate amount of taxes due will not be known until
examinations are completed or the audit periods are closed and settled.

Allowance for Doubtful Accounts

We  make judgments as to our ability to collect outstanding  receivables and provide allowances for

the portion of receivables for which collection is doubtful. Provisions are made based  upon a  specific
review of all significant outstanding invoices. In determining these provisions,  we analyze our historical
collection experience and current economic trends as well as the status of specific receivables. 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.

Accounting for Transfers of Financial Assets

We  derecognize financial assets when control has been  surrendered in  compliance with SFAS

No. 140, ‘‘Accounting for Transfers and Servicing of Financial  Assets and Extinguishments of
Liabilities.’’ Transfers of assets that meet the requirements  of SFAS No.  140 for sale  accounting
treatment are removed from the balance sheet and gains or losses on the sale are recognized. If the
conditions for sale accounting treatment are not met, or are no longer met, these transactions are
accounted for as secured borrowings. The determination of the accounting treatment under SFAS
No. 140 requires significant judgment relative to the determination of whether the criteria to achieve
sale accounting treatment have been achieved, including whether the transferred assets have been
legally isolated from us. We have accounted for all transfers of assets during  fiscal  2005, 2006 and 2007
as secured borrowings. Accordingly, the transferred assets are recorded  as collateralized  receivables in
our consolidated balance sheet and we have accounted for the cash received from these transactions as

45

secured borrowings. Transaction costs associated with secured borrowings,  if any, are treated as
borrowing costs and recognized in interest expense. As customer payments are made on the
collateralized receivables, the collateralized receivable and debt obligation are reduced. Such customer
payments are included in the operating section of our consolidated statements  of cash  flows. The cash
received from and payments made on the secured borrowings are  included in the financing section of
our consolidated statements of cash flows.

Accounting for Restructuring Accruals

We  follow SFAS No. 146, ‘‘Accounting for Costs  Associated with Exit or Disposal Activities’’ in
accounting for restructuring activities. In accounting for these obligations,  we are  required to make
assumptions related to the amounts of employee severance, benefits and related costs and to the time
period over which facilities will remain vacant, sublease terms, sublease rates and discount rates.  We
base our estimates and assumptions on the best information  available at  the time  the obligation has
arisen. These estimates are  reviewed and revised as facts and circumstances dictate; changes in these
estimates could have a material effect on the amount accrued on our balance sheet, the  restructuring
charges incurred and our estimates of future costs under existing restructuring programs.

Accounting for Stock-Based Compensation

We  adopted SFAS No. 123(R), ‘‘Share-Based Payment,’’ effective July 1, 2005. Under the fair  value
provisions of this statement, stock-based compensation cost is measured at the  grant date based on the
value of the award and is recognized as expense over the vesting period. SFAS No. 123(R)  requires
significant judgment and the use of estimates, particularly for assumptions such as stock price volatility
and expected option lives, as well as whether awards with performance conditions will vest, to recognize
stock-based compensation costs. If different assumptions were used, stock-based compensation  expense
and our results of operations could fluctuate significantly.

Summary of Restructuring Accruals

Restructuring Charges Originally Arising in the Three  Months Ended June 30,  2007

In May 2007, we initiated a plan to relocate our corporate headquarters from  Cambridge  to

Burlington, Massachusetts. The relocation resulted in us ceasing to use our prior corporate
headquarters leased space, subleasing that space to a third party, and relocating  to  a new facility.
During fiscal 2007, we recorded a charge of $0.1 million associated with the relocation of certain
departments to temporary space. The closure and relocation actions were completed in October 2007
and resulted in a total restructuring charge of approximately $6.0 million.

Restructuring Charges Originally Arising  in the Three  Months Ended June 30,  2005

In May 2005, we initiated a plan to consolidate several corporate functions and to reduce our
operating expenses. The plan to reduce operating expenses primarily resulted in headcount reductions,
and also included the termination of a contract and the consolidation of facilities. These actions
resulted in an aggregate restructuring charge of $3.8 million, recorded in the fourth quarter of fiscal
2005. During fiscal 2006 and 2007, we recorded an additional $1.8 million and $4.6 million, respectively,
related to headcount reductions, relocation costs and facility consolidations associated with the May
2005 plan that did not qualify for accrual at June 30, 2005.

46

As of June 30, 2007, there was $0.7 million remaining in accrued expenses relating to the

remaining severance obligations and lease payments. The  following  activity was recorded for the

Restructuring Charges originally arising  in  the Three Months Ended June 30, 2004

In June 2004, we initiated a plan to reduce our operating expenses in order to better align our
operating cost structure with the then-current economic environment and to improve our operating
margins. The plan to reduce operating expenses resulted in the consolidation of facilities, headcount
reductions, and the termination of operating contracts. These actions resulted in an aggregate
restructuring charge of $23.5 million, recorded in the fourth quarter of fiscal 2004. During fiscal 2005,
we recorded $14.4 million related to headcount reductions and facility consolidations associated  with
the June 2004 restructuring plan that did not qualify for accrual at June 30, 2004. In addition, we
recorded $0.4 million in restructuring charges related to the accretion of the  discounted restructuring
accrual and a $0.8 million decrease to the accrual related to changes in estimates of severance  benefits
and sublease terms. During the years ended June 30, 2006 and 2007,  we recorded a $0.7 million
increase and a $0.2 million decrease to the accrual primarily due to changes in the  estimate of future
operating costs and sublease assumptions associated with the  facilities

47

As of June 30, 2007, there was $5.1 million remaining in accrued expenses relating to the

remaining severance obligations and lease payments. The  following  activity was recorded for the

Restructuring charges originally arising  in  the Three Months  Ended  December 31, 2002

In October 2002, we initiated a plan to further reduce operating expenses in response to first

quarter revenue results that were below expectations and to general economic uncertainties. In
addition, we revised revenue expectations for the remainder of the fiscal year  and  beyond, primarily
related to the manufacturing/supply chain product line, which had been  affected the most by the
economic conditions. The plan to reduce operating expenses  resulted in headcount reductions,
consolidation of facilities, and discontinuation of development and support for certain non-critical
products. These actions resulted in an aggregate restructuring charge of $28.7  million.  During  fiscal
2004, we recorded a $4.9 million decrease to the accrual related to revised assumptions  associated with
lease exit costs, particularly the buyout of a remaining lease obligation,  and  severance  obligations.
During fiscal 2005, 2006, and 2007 we recorded a $7.0 million and $1.0 million increase and a
$0.2 million decrease, respectively, to the accrual primarily due to a change in the estimate of the
facility vacancy term, extending to the term of the lease.

As of June 30, 2007, there was $8.0 million remaining in accrued expenses relating to the

remaining lease payments. The following activity was recorded for the indicated years (in  thousands):

September 2012

Restructuring charges originally arising  in the Three Months  Ended  June 30, 2002

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 and consolidated facilities, and disposed of certain assets, resulting in an aggregate  restructuring
charge of $13.2 million. During fiscal 2004, we recorded a $1.5 million decrease to the accrual related
to revised assumptions associated with lease exit costs, particularly the  buyout  of  a remaining lease
obligation, and severance obligations. During fiscal 2005, we recorded a $0.2 million increase to the
accrual due to changes in estimates of sublease assumptions and severance settlements. During 2006
and 2007, we recorded less than $0.1 million in increases to the accrual due to changes in sublease
assumptions.

As of June 30, 2007, there was $0.4 million remaining in accrued expenses relating to the

remaining severance obligations and lease payments. The  following  activity was recorded  for the

Comparison of Fiscal 2007 to Fiscal 2006

Revenues. Revenues are derived from software licenses,  consulting  services and maintenance and
training. Total revenues for fiscal 2007 increased 15.8%  to  $341.0 million  from $294.4 million in fiscal
2006. Total revenues from customers outside  the United States  were  $180.0 million  or 52.8% of total
revenues and $168.1 million or 57.1% of total revenues for fiscal 2007 and 2006, respectively. The
geographical mix of revenues can vary from period to period.

Software license revenues represented 58.6% and 52.2% of total  revenues for fiscal 2007 and 2006,

respectively. Revenues from software licenses in fiscal  2007 increased 29.9%  to  $199.8 million  from
$153.7 million in fiscal 2006. Software license revenues are attributable to software license renewals of
term contracts with existing users, the expansion of existing customer relationships through licenses for
additional users, licenses of additional software products, and, to a lesser extent, to the addition of new
customers. We believe that the increase in license revenues  principally reflected continued acceptance
and expansion of our new and existing product offerings, the operational execution of our strategy to
focus on license revenues, as well as strength in our energy, chemicals, and engineering and
construction end-markets.

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 were relatively

50

unchanged at $141.3 million for fiscal 2007 and $140.7 for fiscal 2006 as a 3.0% decline in the
consulting services business, from $64.6 million to $62.7 million, was offset by a 3.3% increase  in
maintenance and training revenues, from $76.1 million to $78.6 million.

Cost of Software Licenses. Cost of software licenses consists of royalties, amortization  of

previously capitalized software costs, costs related to delivery of software, including disk duplication and
third-party software costs, printing of manuals and packaging. Cost of software licenses for fiscal  2007
decreased to $14.6 million from $16.8 million in fiscal 2006. Cost of software licenses as a percentage
of revenues from software licenses decreased to 7.3% for fiscal 2007 from 10.9% for fiscal 2006. The
cost reductions were primarily due to a $1.3 million decrease in amortization of capitalized software
costs associated with lower amounts being capitalized in recent periods, as well as a $0.9 million
decrease in royalty expense associated with the completion of  a long-term fixed royalty contract in June
2006. The reduction in cost as a percentage of revenue is due to the increase in revenue  over a base of
costs which is primarily fixed. We expect the cost of software licenses to continue  to decline in  absolute
amounts due to the continued decline in amortization of capitalized software.

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 fiscal 2007 decreased 0.4% to $72.4 million from $72.7 million for fiscal 2006.
Cost of service and other, as a percentage of revenues from service and other, decreased to 51.3% for
fiscal 2007 from 51.7% for fiscal 2006. The cost reduction was primarily due to a $1.4  million reduction
in reimbursable costs, a $1.7 million reduction in employee compensation costs, and  a $0.3 million
reduction in rent and facility costs, offset in part by a $1.7 million increase in the reclassification of
personnel costs from our development engineers working on a customer application project and  a
$1.5 million increase in third-party consulting costs. We expect the absolute cost of  service  and other to
remain flat as a percentage of service revenue.

Amortization of Technology Related Intangible Assets. Amortization of technology related intangible

assets consists of the amortization from intangible assets from acquisitions.  These assets are generally
being amortized over a period of three to five years. Amortization expense was $6.5 million in fiscal
2007 and $8.6 million in fiscal 2006. The decline in fiscal 2007 was the result of certain intangible assets
becoming fully amortized during the year.  As of June 30, 2007, the balance of  technology related
intangible assets was fully amortized.

Selling and Marketing. Selling and marketing expenses for fiscal 2007 increased 10.5%  to
$93.4 million from $84.5 million for fiscal 2006, declining as a percentage of total revenues to 27.4%
from 28.7%. The increase in cost is primarily due to an increase in commissions of $4.0  million, an
increase in payroll costs of $3.4 million and higher rent and facility costs of $1.2 million. The increases
in selling and marketing costs are due to, and help to further increase our revenues. We expect selling
and marketing expenses to continue to increase in absolute terms, but decline as a percentage of
revenue as our revenue base continues to expand.

Research and Development. Research and development expenses consist of personnel and outside

consultancy costs required to conduct our product development efforts. Research and development
expenses for fiscal 2007 decreased 3.7% to $42.7 million from $44.3 million for fiscal 2006, and
decreased as a percentage of total revenues to 12.5% from 15.1%. The expense reduction primarily
resulted from the allocation of $1.7 million of personnel costs to cost of services and other for
development engineers working on a specific customer application project, a $1.8 million reduction in
payroll costs, a $1.1 million reduction in rent and facility costs, a $0.5 million reduction in consultant
costs, and a $0.4 million reduction in depreciation expense, partially offset by a $4.0 million decrease in
capitalized software development costs. The declines in payroll and facility costs are attributable to cost
efficiencies realized as a result of the consolidation of several research and development locations and

51

re-deployment of resources to more cost effective geographies. Our total research and development
headcount was 365 as of June 30, 2007 compared to 335 as of June 30, 2006.

We  capitalized software development costs that  amounted  to 7.6%  of our  total engineering costs
during fiscal 2007, as compared to 13.9% in fiscal 2006. The amount of capitalized costs decreased in
fiscal 2007 as the development efforts during the year did not meet the criteria for capitalization, a
trend which we expect to continue in fiscal  2008. We expect our research and development expenses  to
increase in absolute terms as a result of the decline in capitalized software development  costs.

General and Administrative. General and administrative expenses consist primarily of personnel

costs of administrative, executive, financial and legal personnel, and outside professional fees. General
and administrative expenses for fiscal 2007 increased 14.9% to $51.0 million  from $44.4 million for
fiscal 2006, and decreased as a percentage of total revenues to 15.0% from 15.1%. This increase in
costs is due to a $2.5 million increase in compensation and related costs, a $4.5 million  increase in
legal, accounting and consulting costs associated with the internal review of accounting for stock
options by the audit committee, professional fees for financial restatements and other matters, offset  in
part by a $1.6 million reduction in bad debt expense. We expect our general and  administrative
expenses to be approximately flat due to continued investments in personnel and systems necessary to
remediate our material control weaknesses.

Restructuring Charges and FTC Legal Costs. During fiscal 2007, we recorded $4.6 million in
restructuring charges for headcount reductions and office closures associated with the May 2005  plan
that occurred during the year, and less than $0.1 million for revisions of estimates associated  with lease
exit costs and accretion of the discounted restructuring accruals under previous restructuring plans.
During fiscal 2006, we recorded $4.0 million in restructuring charges. Of this amount, $1.8 million
related to headcount reductions, relocation costs and facility consolidations  associated with the May
2005 plan that did not qualify for accrual at June 30, 2005. The remaining $2.2 million relates to
revisions of estimates associated with lease exit costs and accretion of the discounted  restructuring
accruals under previous restructuring plans.

Interest Income.

Interest income was $21.9 million in for fiscal 2007 compared to $20.0 million for

fiscal 2006. Interest income is generated from investment of excess cash invested in highly liquid short
term instruments, and from the accretion of interest for software licenses  sold  pursuant to long term
installment contracts. Under these installment contracts, customers have the option  to  make  annual
payments over the license term or to make a single license fee payment at the outset of the term.
Historically, a substantial majority of customers have elected to make annual payments.  The  increase in
interest income is due to the increases in our cash balance and an increase in our collateralized
receivables, which is partially offset by reductions in installments  receivable  balances  due from
customers.

We  have pledged a portion of the installments  receivable  contracts to unrelated financial

institutions and unconsolidated entities as collateral for secured borrowings and recorded the  value of
these installments as collateralized receivables on the accompanying consolidated balance sheets.

Interest Expense.

Interest expense is incurred primarily from our secured borrowings. The secured

borrowings are derived from our securitizations and borrowing arrangements with unrelated financial
institutions. Interest expense in fiscal 2007 decreased to $18.6 million from $19.5 million in fiscal 2006.
This decrease in interest expense resulted from a generally lower level of secured borrowings
particularly higher interest bearing borrowings, during fiscal 2007

Foreign Currency Exchange Gain (Loss). Foreign currency exchange gains and losses are primarily
incurred as a result of the revaluation of intercompany accounts denominated in foreign currencies and
reflect movement in exchange rates relative to the U.S. dollar. The revaluation adjustments are
primarily unrealized gains and losses as the related intercompany balances typically have not settled in

52

cash. In fiscal 2007, we recorded a foreign currency exchange loss of $0.7 million,  compared to a
$2.9 million loss in fiscal 2006. This decrease was primarily due to favorable  exchange rate fluctuations.

Provision for/Benefit from Income Taxes. We recorded a provision for income taxes of

$12.4 million for fiscal 2007, primarily related  to our income in foreign jurisdictions, withholding taxes
imposed on license fees paid to us from customers outside the  U.S., and changes in estimates for tax
contingency reserves, principally from foreign operations. The income tax  provision also includes state
income taxes. We do not record a federal income tax  provision on our domestic income since we are
able to reduce such standard provision by net operating loss, or NOL, carryforwards that expire  at
various dates from 2008 through 2025 and available tax credits. These NOL carryforwards and tax
credits have historically been offset by a valuation allowance for  accounting purposes, and as a result,
the use of an NOL generally results in a current income statement benefit to substantially  offset federal
provisions. In addition to regular NOL carryforwards, we also have NOL that was generated by excess
stock compensation deductions that are recognized when they are realized. The remaining $38.2 million
in NOL’s at June 30, 2007 includes $36.9 million of excess stock compensation tax benefits  that upon
realization will be credited to additional paid-in capital.

We  recorded a provision for income taxes  of $9.9 million for fiscal 2006. The  increase in the
provision in fiscal 2007 was attributable to higher foreign taxes resulting from increased taxable income
outside the U.S. In addition, the provision for tax contingencies was $6.0 million in fiscal 2007
compared to $3.4 million in fiscal 2006.

Comparison of Fiscal 2006 to Fiscal 2005

Revenues. Total revenues for fiscal 2006 increased  9.4% to $294.4 million  from $269.1 million in
fiscal 2005. Total revenues from customers outside  the United States  were  $168.1 million  or 57.1% of
total revenues and $162.3 million or 60.3% of total revenues for  fiscal 2006 and 2005, respectively.  The
geographical mix of revenues can vary from period to period.

Software license revenues represented 52.2% and 47.9% of total  revenues for fiscal 2006 and 2005,

respectively. Revenues from software licenses in fiscal  2006 increased 19.3%  to  $153.7 million  from
$128.8 million in fiscal 2005. We believe that the increase principally reflected strength in our energy
end-market, as well as continued strength in our chemicals and  engineering and construction
end-markets, combined with the increased efforts and time that our management were able  to  dedicate
to software license activities, and the increased willingness of our customers to make investments  in our
products, following the resolution of the FTC proceedings and an audit committee investigation in
fiscal 2005.

Revenues from service and other for fiscal  2006 increased 0.3% to $140.7 million from

$140.3 million for fiscal 2005. A decrease of 0.9% in the consulting services business was offset by an
increase of 1.3% in maintenance and training revenues. Consulting services declined due  to  the
December 2004 sale of a portion of our consulting business to Honeywell, as part of our settlement
with the FTC.

Cost of Software Licenses. Cost of software licenses for fiscal 2006 decreased to $16.8 million from
$16.9 million in fiscal 2005. Cost of software licenses as a percentage of revenues from software licenses
decreased to 10.9% for fiscal 2006 from 13.1% for fiscal 2005. The reduction in cost as a percentage of
revenue was due to the increase in revenues over a base of costs, of which many were fixed in nature.

Cost of Service and Other. Cost of service and other for fiscal 2006 decreased 12.1% to

$72.7 million from $82.7 million for fiscal 2005. Cost of service and other, as a percentage of revenues
from service and other, decreased to 51.7% for fiscal 2006 from 59.0% for fiscal 2005. The decrease in
cost is primarily due to decreased payroll costs of $10.4 million and decreased rent and facility costs of
$3.5 million related to reductions in headcount and facility consolidations, offset in part by increases of

53

$0.8 million in reimbursable costs and  $2.1 million in stock-based compensation costs and the allocation
of $1.0 million of personnel costs for our development engineers working on  a customer  application
project.

Amortization of Technology Related Intangible Assets. Amortization expense was $8.6 million for

fiscal 2006 and $8.2 million for fiscal 2005. The increase was primarily the result of changes in foreign
currency translation rates affecting amortization expense incurred in subsidiaries operating  in currencies
other than the U.S. dollar.

Selling and Marketing. Selling and marketing expenses for fiscal 2006 decreased  12.3% to
$84.5 million from $96.3 million for fiscal 2005, while decreasing as a percentage of total revenues to
28.7% from 35.8%. The reduction in cost was primarily due to a decrease in payroll costs of
$4.0 million, lower rent and facility costs of $5.9 million, lower marketing and advertising costs of
$2.2 million, lower travel expenses of $1.5 million and a $2.7 million decrease in advertising costs
related to AspenWorld, which took place in October 2004, partially  offset by  a $3.0  million increase in
stock-based compensation costs and a $1.3 million increase in commissions.

Research and Development. Research and development expenses for fiscal 2006 decreased 6.3% to

$44.3 million from $47.3 million for fiscal 2005, and decreased as a percentage of total  revenues to
15.1% from 17.6%. The decrease was primarily  attributable to the allocation  of $1.0  million  of
personnel costs to costs of services for development engineers working on a customer application
project, a $0.7 million decrease in payroll costs, a $1.7 million reduction in consultant  costs, a
$1.0 million reduction in depreciation and a $0.5 million decrease in rent and facility costs, partially
offset by a $1.2 million decrease in software costs eligible for capitalization and a $1.5  million  increase
in stock-based compensation costs.

We capitalized software development costs that amounted to 13.9%  of our  total  engineering  costs

during fiscal 2006, as compared to 15.3% in fiscal 2005.

General and Administrative. General and administrative expenses for fiscal 2006 decreased 14.5%
to $44.4 million from $51.9 million for fiscal 2005, and decreased as a percentage of total  revenues to
15.1% from 19.3%. This decrease was due to a $7.1 million reduction in legal,  accounting  and
consulting costs associated with the internal investigation by the audit committee, a $1.9 million
decrease in payroll costs and a $1.2 million reduction in rent and facility  costs, partially offset by a
$3.3 million increase in stock-based compensation costs and increased recruiting costs  of  $0.7 million.

Restructuring Charges and FTC Legal  Costs. During fiscal 2006, we recorded an additional

$1.8 million related to headcount reductions, relocation costs and facility consolidations  associated with
the May 2005 restructuring plan that did not qualify for accrual at June 30, 2005.  The remaining
$2.2 million related to revisions of estimates associated with lease exit costs and accretion of the
discounted restructuring accruals under previous restructuring plans. During fiscal 2005, we recorded
$25.0 million in restructuring charges and FTC legal costs. Of this amount,  $14.4 million related to
headcount reductions and facility consolidations associated with the June 2004 restructuring plan that
did not qualify for accrual at June 30, 2004, $3.8 million related to the May 2005 restructuring charge,
$0.4 million related to the accretion of discounted restructuring accruals, and $6.5 million related to
adjustments to prior restructuring accruals, all offset by $0.2 million in FTC legal costs, related to the
FTC challenge of our acquisition of Hyprotech.

Interest Income.

Interest income was $20.0 million for fiscal 2006 as compared to $19.0 million in

fiscal 2005. The increase in interest income was due to the increases in our cash balance, partially
offset by reductions in installments receivable balances due from customers.

We  have pledged a portion of the installments receivable  contracts to unrelated financial

institutions as collateral for secured borrowings and recorded the value of these installments as

54

collateralized receivables on the accompanying consolidated balance sheets. We pledged a  lower volume
of customer installments receivable in fiscal 2007 than the prior year due to our  improved working
capital position and increases in our profitability and cash flows from operations.

Interest Expense.

Interest expense is incurred primarily from our secured borrowings.  The  secured

borrowings are derived from our securitizations and borrowing arrangements with unrelated financial
institutions. Interest expense in fiscal 2006 increased to $19.5 million from $16.8  million in fiscal 2005.
This increase in interest expense resulted from a generally higher level  of  secured borrowings during
fiscal 2007.

Foreign currency exchange gain (loss). Foreign currency exchange loss for fiscal 2006  decreased  to

$2.9 million from $3.4 million for fiscal 2005 primarily due to favorable exchange rate fluctuations.

Provision for/Benefit from Income Taxes. We recorded a provision for income taxes  of $9.9 million
for fiscal 2006 compared to $8.8 million for fiscal 2005. The increase in the provision in fiscal 2006 was
attributable to higher foreign taxes resulting from increased taxable income outside  the U.S.

Quarterly Results

Our 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, including purchasing patterns, timing of introductions of
new solutions and enhancements by us and our competitors, and fluctuating economic conditions.
Because license fees for our software products are substantial and the implementation of our solutions
often involve the services of engineers over an  extended period of time, the  sales process for our
solutions is lengthy and can exceed one year. Accordingly, software revenues are difficult to predict,
and the delay of any order could cause our quarterly revenues to fall substantially below expectations.
Moreover, to the extent that we succeed in shifting customer purchases away  from point solutions and
toward integrated solutions, the likelihood of delays in ordering may  increase  and  the effect of any
delay may become more pronounced.

We  ship software products within a short period after  receipt of an order  and usually do not have

a material backlog of unfilled orders of software products. Consequently, revenues from  software
licenses, including license renewals, 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
been derived from license agreements  that have been consummated in the  final weeks of the quarter.
Therefore, even a short delay in the consummation of an agreement may cause revenues to fall below
expectations for that quarter. Since our expense levels are based in part on anticipated revenues, we
may be unable to adjust spending in a timely manner to compensate for any revenue shortfall and any
revenue shortfall would likely have a disproportionately adverse effect on net income. We expect that
these factors will continue to affect our operating results for the foreseeable future.

Liquidity and Capital Resources

Resources

We  historically have financed our operations  through cash generated from  operating activities,
public offerings of our convertible debentures and common stock, private offerings of our preferred
stock and common stock, borrowings secured by our installment receivable contracts and borrowings
under bank credit facilities. As of June 30, 2007, we had cash and cash equivalents totaling
$132.3 million. We believe our current cash balances, future  cash flows from  our operations, and cash
from future borrowings secured by installment receivable contracts will be sufficient to meet our
anticipated cash needs 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.  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.

Operating Cash Flow

In fiscal 2007, operating activities provided $55.7 million of cash as net income, plus non-cash
expenses for stock-based compensation and depreciation and amortization totaling  $30.5 million, was
partially offset by a $30.9 million increase  in installments receivables, primarily related to the  sale of
receivables to Key Bank, the proceeds from which are presented as a component of cash from
financing activities. Accrued expenses increased by $1.8 million due to increases  in  accruals for  income
taxes and professional fees associated with the restatement of our financial  statements.

Financing Activities

In fiscal 2007, cash used in by financing activities was $2.2 million primarily due to the cash
payment of $34.0 million for accumulated dividends upon the conversion of Series D-1 and  Series D-2
preferred into common stock in December 2006 and January 2007. This was partially offset by
$8.5 million in proceeds from employee stock plans along with net proceeds in excess of secured
borrowing payments which was $23.7 million, primarily resulting from the $20.0 million of proceeds
upon the closing of the securitization facility in the first quarter of fiscal 2007.

Historically, we have financed our operations principally through cash generated from public
offerings of our convertible debentures and common stock, private offerings of our preferred stock and
common stock, operating activities, and borrowings secured by our installment receivable contracts.

Borrowings collateralized by receivable contracts

Traditional Programs

We  historically have maintained arrangements with  financial  institutions providing for borrowings

that are secured by our installment and other receivable contracts, and for which limited recourse exists
against us. Under our arrangements with General Electric Capital Corporation, Bank of America and
Silicon Valley Bank, which we refer to as the Traditional Programs,  both  parties must agree to enter

60

into each transaction and negotiate the borrowing amount and interest rate secured by each receivable.
The customers’ payments of the underlying receivables fund the repayment  of  the related  borrowing
amount. The weighted average interest rate on the secured borrowings was 7.5% at June 30,  2007.

The amount of total collateralized receivables for the Traditional Programs approximates the
amount of the secured borrowings recorded in the consolidated balance  sheet. The collateralized
receivables earn interest income and the secured borrowings accrue borrowing costs at  approximately
the same interest rates. The secured borrowings and collateralized receivables are reduced as the
related customer receivable is collected. The terms of  the customer  accounts receivable range  from
amounts that are due within 30 days to installment receivables that are due over  five  years.  We act as
the servicer for the receivables in one of the three arrangements.

Under these arrangements, we received aggregate cash proceeds of $115.7 million, $110.5 million

and $148.9 million during fiscal 2005, 2006 and 2007, respectively. As of June  30, 2007, we had
outstanding secured borrowings of $180.3 million that were secured by collateralized receivables
totaling $183.2 million.

Availability under these arrangements is dependent upon our generation of additional  customer
receivables and the financial institutions’ willingness to continue to enter  into  these transactions.  We
estimate that there was in excess of $64.0 million available under the Traditional Programs at  June 30,
2007. We expect to continue to have the ability  to  borrow under  the Traditional Programs, as the
collection of the collateralized receivables and resulting payment of the borrowing obligation will
reduce the outstanding balance, and the availability under the arrangements can be increased.

Under the terms of the Traditional Programs, we have transferred  the receivables to the  financial
institutions with limited financial recourse. Potential recourse obligations are primarily related to one
program that requires us to pay interest to the financial institution when the underlying customer has
not paid by the installment due date. This recourse is limited to a maximum period of 90  days after the
due date. The amount of outstanding installment receivables that has this potential recourse obligation
is $51.5 million at June 30, 2007. This recourse obligation is recognized as interest expense as incurred
and totaled $0.5 million, $0.4 million, and $0.7 million for the years ended June 30, 2005,  2006, and
2007, respectively. In addition, we have recourse obligations totaling $1.5 million at June 30, 2007  if the
underlying installment receivable is not paid by the customer. This recourse obligation is in the  form of
a deferred payment by the financial institution that is withheld until customer payments are received.
Otherwise, recourse generally results from circumstances in which we failed to perform requirements
related its contracts with the customer. Other than the specific items noted above, the financial
institutions bear the credit risk associated with the customer whose receivable it purchased.

Securitization of Accounts Receivable

The securitization transactions in fiscal 2005 and 2007 described below include  collateralized
receivables whose value exceeds the related borrowings from the financial institutions. We receive and
retain collections on these securitized receivables after all borrowing and related costs are paid to the
financial institution. The financial institutions’ rights to repayment are limited to the payments received
from the collateralized receivables. The carrying value of the collateralized receivables at June 30, 2007
under these arrangements was $61.9 million and the secured borrowings totaled $25.8 million. The
collateralized receivables earn interest income and the secured borrowings result in interest expense.
The secured borrowings incur a higher interest rate than the implicit rates in the receivables. We act as
the servicer under both of these arrangements and the customer collections are used to repay the
secured borrowings, interest, and related costs.

Fiscal 2005 Securitization

On June 15, 2005, we securitized and transferred installments receivable with  a net carrying value
of $71.9 million and received cash proceeds of $43.8 million. The transfers of installments  receivable  to
the securitization facility did not qualify as a sale for accounting purposes and has been  accounted for
as a secured borrowing. These borrowings are secured by collateralized receivables and the debt and
borrowing costs are repaid as the receivables are collected. We capitalized $2.1 million  of  debt  issuance
costs associated with this transaction and these costs are being recognized in interest  expense using the
effective interest method. Accumulated amortization of the debt issue  costs were $1.2 million and
$1.9 million at June 30, 2006 and 2007, respectively. Amortization expense of the debt issuance costs
was $1.1 million and $0.7 million for the years ended June 30, 2006 and 2007, respectively.

Fiscal 2007 Securitization

On September 29, 2006, we entered into a three-year revolving securitization facility and
securitized and transferred installments receivable with a net carrying  value of $32.1 million and
received cash proceeds of $20.0 million. The transfers of installments  receivable  to  the securitization
facility did not qualify as a sale for accounting purposes and have been accounted for as  a secured
borrowing. These borrowings are secured by collateralized receivables and the  debt and borrowing costs
are repaid as the receivables are collected. We capitalized $1.1  million of debt issuance costs associated
with this transaction and these costs are being recognized in interest expense using the effective interest
method. Accumulated amortization of the debt  issue costs was $0.4 million at June  30, 2007.

In December 2007, we paid the outstanding amount of the Fiscal 2005 securitization at its carrying

value. The unamortized debt issue costs were charged to expense at the time.

We  had been in violation of certain covenants related to the Fiscal 2007  Securitization due to the

delay in filing our financial statements and other violations. The secured  borrowings under this
arrangement have been classified in the current portion of secured borrowings. In March 2008, we  paid
the outstanding amount of the Fiscal 2007 Securitization at its carrying value plus  a termination fee of
$0.8 million, and this securitization is no longer available. The unamortized debt issue costs were
charged to expense at the time.

Credit Facility

In January 2003 and through subsequent amendments, we executed a loan arrangement with
Silicon Valley Bank. This arrangement provides a line of credit of up to the lesser of (1) $15.0 million
or (2) 70% of eligible domestic receivables, and a line of credit of up  to  the lesser of (1) $10.0 million
or (2) 80% of eligible foreign receivables. The lines of credit bear interest at the  bank’s prime rate
(8.25% at June 30, 2007). We are required to maintain a $4.0 million compensating  cash balance with
the bank, or be subject to an unused line of credit fee and collateral handling fees. The  lines of  credit
are 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 and installments receivable that are not already
pledged as collateral against the secured borrowings. We are required to meet certain financial
covenants, including minimum tangible net worth, minimum cash balances and an adjusted quick ratio.
The terms of the loan arrangement restrict our ability to pay dividends, with the exception of dividends
paid in common stock or preferred stock dividends in cash.

As of June 30, 2007, there were $7.4 million in letters of credit outstanding under the line of
credit, and there was $13.1 million available for future borrowing. On October 16, 2007, we executed
an amendment to the Loan Arrangement that adjusted the terms of certain financial covenants,
including modifying the date we must provide monthly unaudited and annual audited financial
statements to the bank. The loan arrangement expires in May 2008. We are  currently in negotiations to

62

either: (i) extend this line of credit with our current lender and amend the terms of the facility; or
(ii) obtain a facility from another lender.

Requirements

Capital Expenditures

In fiscal 2007, investing activities used $7.9 million of cash primarily as a  result of the capitalization

of internal use computer software development costs and the ordinary purchases of property  and
equipment. In fiscal 2005 and 2006, investing activities used $11.8 million and  $10.5 million of cash,
respectively. We expect to spend $8.0 million for capital  expenditures in fiscal 2008, primarily for
additional purchases of internal use software and computer equipment. We are not  currently party to
any purchase contracts related to future capital expenditures.

Management is currently implementing a computer system and other related  changes, which are

being designed and implemented in part to remediate our material weaknesses and  significant
deficiencies. Management currently believes that the costs for such remediation activities, a  substantial
portion of which are expected to be incurred to upgrade our existing financial applications, could be
material.

Contractual obligations and requirements

As described above, we have transferred receivables under our receivable sale  facilities and these
transactions have been classified as secured borrowings for accounting purposes.  Repayment of these
borrowings are funded by the payments made by the customer either directly  to  the applicable financial
institution or to us as agent, with limited or no financial recourse to us. Accordingly, we  do  not  have
any contractual obligation to fund these payments, as the scheduled payments are not our obligation
and there are no financial guarantees issued in relation to these  transactions. The table  below excludes
these transactions as we  do not have a contractual payment obligation.

Our contractual obligations at June 30, 2007 primarily consisted of operating leases for our
headquarters and other facilities, sub-contractor purchase commitments,  and other debt obligations.
Other than these, there were no other commitments for capital or other expenditures. Our obligations
related to these items at June 30, 2007 were as follows (in thousands):

Total contractual future sublease rental income as  of  June 30, 2007 was $7.2 million, which  is not

included in the above table.

On September 5, 2007, we entered into an additional sublease agreement related to our former
office space in Cambridge, Massachusetts, effective October 1, 2007 for approximately 50,000 square
feet that expires on September 30, 2012. This new sublease agreement represents $5.5 million of
scheduled sublease payments not included in the above table.

Effective September 1, 2007, the landlord terminated a portion of our lease in Houston, Texas with

respect to approximately 14,000 square feet of the original leased space. This termination agreement
has not been included in the above table and represents future reductions of $2.6 million in lease
payments.

See Note 12 of the Notes to the Consolidated Financial Statements under the  caption of

‘‘Operating Leases’’ for additional disclosure.

Income Taxes

We  have recorded $28.7 million for estimated  tax  liabilities  including $22.0 million  for estimated

tax contingencies as further described in Note 11 of the Notes to the Consolidated Financial
Statements. The actual amounts incurred upon settlement of these estimated liabilities could be
materially different than the estimates recorded, and the timing of potential settlement for the  matters
which comprise the estimated liability is not presently known.

Dividends

In accordance with our charter, upon each conversion of shares of our Series  D-1  or D-2

convertible preferred stock into common stock, we paid a cash dividend in the  amount  of the dividends
accumulated with respect to those shares from their original issue date to the conversion date. We paid
to the holders of those shares a total of $2.4 million upon the conversion of 30,000 shares of Series D-1
convertible preferred stock into 3,000,000 shares of common stock in May 2006 and an additional
$27.4 million upon the conversion of the remaining 270,300 shares of Series D-1 convertible preferred
stock into 27,030,000 shares of common stock in December 2006. We paid $6.6 million to the  holder  of
our Series D-2 convertible preferred stock upon  conversion of all of the 63,064  outstanding shares  of
such preferred stock into 6,306,400 shares of common stock in January 2007.

Retirement of Convertible Debt

On June 15, 2005, we paid $58.2 million to retire the entire outstanding principal amount of  our

convertible debentures, together with interest accrued thereon. We  funded this payment  with
(a) $8.6 million of our existing cash, (b) $5.8 million obtained from borrowings secured by our  sales  of
installments receivable under our existing receivables programs with Silicon Valley Bank and GE
Capital Corporation, and (c) $43.8 million through the Fiscal 2005 securitization  transaction described
above.

Inflation

Inflation has not had a significant impact on our operating results to date and we do not expect

inflation to have a significant impact during fiscal 2008.

New Accounting Pronouncements

In July 2006, the Financial Accounting Standards Board (FASB)  issued Interpretation  No. 48,

‘‘Accounting for Uncertain Tax Positions, an  Interpretation  of FASB Statement No. 109,’’  or FIN 48,
which clarifies the criteria for recognition and measurement of benefits from uncertain tax positions.
Under FIN 48, an entity should recognize a tax benefit when it is ‘‘more-likely-than-not,’’ based on the
technical merits, that the position would be sustained upon examination by a taxing authority. The
amount to be recognized, if the ‘‘more-likely-than-not’’ threshold was passed, should be measured as
the largest amount of tax benefit that is greater than 50 percent likely of being realized upon ultimate
settlement with a taxing authority that has full knowledge of all relevant information. Furthermore, any
change in the recognition, derecognition or measurement of a tax position should be recognized in the
period in which the change occurs.

We  adopted FIN 48 as of July 1, 2007, and any change  in net assets as  a  result of applying FIN 48

is recognized as an adjustment to accumulated deficit on that date. As a result of the implementation
of FIN 48 on July 1, 2007, we recognized an increase of approximately $3.0 million in the liability for
unrecognized tax benefits, which was accounted for as an increase to the accumulated deficit. In

64

addition, as of July 1, 2007, we had $7.4 million of deferred tax assets which have been derecognized
upon adoption of FIN 48. These amounts did not result in an adjustment to the  accumulated  deficit at
July 1, 2007 as a result of the full valuation allowance recorded against these deferred tax  assets.

We have historically accounted for interest and penalties related to uncertain tax positions as part
of our provision for income taxes. Upon adoption of FIN 48, we will continue this classification. As of
June 30, 2007, we had accrued $6.9 million of interest and penalties related to uncertain tax positions.
Prior to July 1, 2007, we classified income  taxes payable  as  a  current liability. Under FIN 48, we are
required to classify those obligations that are expected to be paid within the next twelve months  as a
current obligation and the remainder as a non-current obligation. As of July 1, 2007, we classified
$10.6 million as non-current obligations.

In September 2006, the FASB issued SFAS No. 157, ‘‘Fair Value Measurements.’’ SFAS No.  157

establishes a framework for measuring fair value in generally accepted accounting  principles and
expands disclosures about fair value measurements. SFAS No. 157  emphasizes that  fair value
measurement is market-based, not entity-specific, and establishes a fair value hierarchy in  which the
highest priority is quoted prices in active markets. Under SFAS No. 157, fair value measurements are
disclosed according to their level within this hierarchy. SFAS No. 157 is effective for fiscal years
beginning after November 15, 2007 except for nonrecurring fair value measurements of  nonfinancial
assets and nonfinancial liabilities, for which the effective date is fiscal  years  beginning after
November 15, 2008. We have not yet determined the effect that  the application of SFAS  No. 157  will
have on our consolidated financial statements.

In February 2007 the FASB issued SFAS No.  159, ‘‘The Fair  Value  Option for Financial  Assets and
Financial Liabilities.’’ SFAS No. 159 permits entities to measure many  financial instruments and certain
other items at fair value and provides entities with the opportunity to mitigate volatility in reported
earnings caused by measuring related assets and liabilities  differently without  having to apply  complex
hedge accounting provisions. Once an entity has elected the fair value option  for  designated  financial
instruments and other items, changes in fair value must be recognized in the statement of operations.
SFAS No. 159 is effective for fiscal years  beginning  after November 15,  2007. We  have not yet
determined the effect that the application of SFAS No. 159 will have on our consolidated financial
statements.

In December 2007, the FASB issued SFAS No. 141(R), ‘‘Business Combinations,’’  which replaces
SFAS No. 141. SFAS No. 141R establishes principles and requirements for how an  acquirer  recognizes
and measures in its financial statements the identifiable  assets acquired, the liabilities assumed,  any
noncontrolling interest in the acquiree and the goodwill acquired. The Statement also establishes
disclosure requirements which will enable users to evaluate the nature and financial effects of the
business combination. SFAS No. 141R is effective for fiscal years beginning after  December 15,  2008.
We expect SFAS No. 141R will have  an impact  on  accounting for business combinations once  adopted
but the effect will be primarily dependent upon future acquisitions.

In December 2007, the FASB issued SFAS No. 160, ‘‘Noncontrolling Interests in Consolidated
Financial Statements—an amendment of Accounting Research Bulletin No. 51,’’ (‘‘SFAS No. 160’’)
which establishes accounting and reporting standards for ownership interests in subsidiaries held by
parties other than the parent, the amount of consolidated net income attributable to the parent and to
the noncontrolling interest, changes in a parent’s ownership interest and the valuation of retained
noncontrolling equity investments when a subsidiary is deconsolidated. The Statement also establishes
reporting requirements that provide sufficient disclosures that clearly identify and distinguish between
the interests of the parent and the interests of the noncontrolling owners. SFAS No. 160 is effective for
fiscal years beginning after December 15, 2008. We have not yet determined the effect that  the
application of SFAS No. 160 will have on our consolidated financial statements, although no minority
interests are reported as of June 30, 2007.

65

In March 2008, the FASB issued SFAS No. 161, ‘‘Disclosures about Derivative Instruments and
Hedging Activities, an amendment of FASB Statement  No. 133.’’ This statement changes the disclosure
requirements for derivative instruments and hedging activities. SFAS No. 161 requires enhanced
disclosures about (a) how and why an entity uses derivative instruments, (b) how derivative instruments
and related hedged items are accounted for under SFAS No. 133 and its related interpretations, and
(c) how derivative instruments and related hedged items affect an  entity’s financial position, financial
performance, and cash flows. This statement is effective for financial statements issued for fiscal years
and interim periods beginning after November 15, 2008. We have  not  yet determined the effect that the
application of SFAS No. 161 will have on our consolidated financial  statements.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

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. We do not expect any material loss with respect to our investment  portfolio  from changes in
market interest rates or credit losses. At June 30, 2007, all of the instruments in our investment
portfolio were included in cash and cash equivalents.

Impact of Foreign Currency Rate Changes

During fiscal 2007, the U.S. dollar weakened against currencies for countries in which we have
local operations, primarily in Europe, Canada and the Asia-Pacific region. The remeasurement of our
intercompany receivables and payables are recorded as unrealized  transactions  gains  or losses in our
consolidated statement of operations as foreign currency exchange gain (loss) unless such intercompany
foreign currency balances qualify for accounting as a translation adjustment  within stockholders’ equity.
Our primary foreign currency exposures relate to customer installment receivables,  which are foreign
denominated. Foreign exchange forward contracts are purchased  to  hedge certain  customer accounts
and installments receivable contract amounts (both held and transferred) that are denominated  in a
foreign currency.

Foreign Exchange Hedging

We  enter into foreign exchange forward  contracts to mitigate our exposure to currency fluctuations

on customer installments receivable contracts denominated in foreign currencies. We  do not use
derivative financial instruments for speculative or trading purposes, however,  our  derivative positions
are not accounted for as accounting hedges. We had $26.9 million of foreign exchange forward
contracts denominated in British, Japanese, Swiss, Euro and Canadian currencies, which  related  to
underlying customer installments receivable transactions at June 30, 2007.  The underlying customer
installments receivable transactions consisted of assets carried on our balance sheet, for which we retain
the exposure associated with changes in foreign exchange  rates.  At each balance  sheet date,  the foreign
exchange forward contracts and the related installment receivable contracts denominated in foreign
currencies are revalued based on the current market exchange rates. Resulting gains and losses are
included in earnings. Gains and losses related to these instruments for fiscal 2007 were not material to
our financial position. We do not anticipate any material adverse effect on our consolidated financial
position, operating results or cash flows resulting from the use of these instruments. There can be no
assurance, however, that these strategies will be effective or that transaction losses can be limited or
forecasted accurately.

The following table summarizes our forward contracts to sell foreign currencies for U.S. dollars at

June 30, 2007. All of these contracts represented customer accounts and installments receivable
contracts. The table presents the value of the contracts in U.S. dollars at the contract exchange rate as

$0.6 million.

Installment receivable contracts

The installment receivable contracts are financial instruments subject  to  market  risk from changes

in interest rates. Fluctuations in interest rates of 1% would result in approximately a $3.5  million dollar
change on the fair market value of the receivables.

Item 8. Financial Statements and Supplementary  Data

Our consolidated financial statements are filed as a part of this  Form  10-K beginning on page F-1

and are incorporated herein by reference.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

On January 10, 2008, Deloitte & Touche LLP (‘‘Deloitte’’) informed our  Audit Committee that
Deloitte declined to stand for re-appointment as our independent registered public  accounting firm for
the fiscal 2008 audit. However, Deloitte agreed to be engaged for  the review of  our interim
consolidated financial statements included in our Quarterly Report on  Form  10-Q for the quarter
ended September 30, 2007. On March 12, 2008, the Audit Committee appointed KPMG LLP as  our
independent registered public accounting firm for the fiscal year ending June 30, 2008.

During the fiscal years ended June 30, 2006 and 2007 and through the subsequent interim period

preceding such resignation, there was no disagreement between us and Deloitte  on any matter  of
accounting principles or practices, financial statement disclosure,  or auditing  scope or procedure  that, if
not resolved to Deloitte’s satisfaction, would have caused Deloitte to make reference to the subject
matter of the disagreement in connection with its audit  report. There were no ‘‘reportable events’’ as
that term is described in Item 304(a)(1)(v) of Regulation  S-K during  the fiscal years ended June  30,
2006 and 2007 or the subsequent interim periods through September 30, 2007, except for the material
weaknesses in our internal control over financial reporting as of June 30, 2007 reported in Item 9A of
this Form 10-K. Deloitte has not expressed any opinion on our internal control over financial reporting
on any date subsequent to June 30, 2007.

Item 9A. Controls and Procedures

Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer and chief financial officer,

evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2007. The term
‘‘disclosure controls and procedures,’’ as defined in Rules 13a-15(e) and 15d-15(e) under the Securities
Exchange Act,  means controls and other procedures of a company that are designed  to  ensure that

67

information required to be disclosed by a company in the reports that it files or  submits under the
Securities Exchange Act is  recorded,  processed, summarized and reported, within the time periods
specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation,
controls and procedures designed to ensure that information required to be disclosed by  a company  in
the reports that it files or submits under the Securities Exchange Act is accumulated  and communicated
to the company’s management, including its principal executive  and  principal  financial  officers, as
appropriate to allow timely decisions regarding required disclosure. Management recognizes that any
controls and procedures, no matter how well designed and operated, can provide only  reasonable
assurance of achieving their objectives and management necessarily applies its  judgment in evaluating
the cost-benefit relationship of possible controls and procedures. Based  on  the evaluation of our
disclosure controls and procedures as of June 30, 2007, and due to the material weaknesses in our
internal control over financial reporting described in our accompanying Management’s Report on
Internal Control over Financial  Reporting, our chief executive officer and chief financial officer
concluded that, as of such date, our disclosure controls and procedures were not effective at the
reasonable assurance level.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control  over

financial reporting for our company. Internal control over financial reporting is defined in
Rule 13a-15(f) and 15d-15(f) promulgated  under the Exchange Act, as a process designed by, or under
the supervision of, a company’s principal executive and principal financial officers and  effected  by the
company’s board of directors, management and other personnel, to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of financial  statements  for external
purposes in accordance with generally accepted accounting principles and includes those policies  and
procedures that:

• pertain to the maintenance of records that in reasonable detail accurately and fairly  reflect the

transactions and dispositions of the assets of the company;

• provide reasonable assurance that transactions are recorded  as necessary to permit preparation
of financial statements in accordance with generally accepted accounting principles, and that
receipts and expenditures of the company are being made only in accordance with authorizations
of management and directors of the company; and

• provide reasonable assurance regarding  prevention or  timely detection of  unauthorized

acquisition, use or disposition of the company’s assets that could have a material effect on the
financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or
detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the
risk that controls may become inadequate because of changes in conditions, or that the degree of
compliance with the policies or procedures may deteriorate.

Our management, including our chief executive officer and chief financial officer, assessed the

effectiveness of our internal controls over financial reporting as of June 30, 2007. In connection with
this assessment, we identified the following five material weaknesses in internal control over financial
reporting as of June 30, 2007. A material weakness is a deficiency, or a combination of deficiencies, in
internal control over financial reporting such that there is a reasonable possibility that a material
misstatement of the annual or interim financial statements will not be prevented or detected on a
timely basis. In making this assessment, our management used the criteria set forth by the Committee
of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework.
Because of the material weaknesses described below, management believes that, as of June 30, 2007,
our internal control over financial reporting was not effective based on this criteria.

68

1)

Inadequate and ineffective controls over the periodic financial close process

We did not have adequate design or operation of controls that provided reasonable assurance

that financial statements could be prepared in accordance with GAAP. Specifically, we did not have
adequate controls and procedures with respect to the (a) accounting for complex non-routine
transactions, including the accounting for transfers of installment and accounts receivable as
discussed below; (b) sufficient personnel with an appropriate  level of technical  accounting
knowledge, experience, and training; (c) review of manual journal entries recorded; (d) timely
preparation and review of period-end account analyses and timely disposition of any  required
adjustments; (e) proper consolidation and accounting for all intercompany activities including those
denominated in local currencies; and (f) timely reconciliation and recording of stock-based  awards.
This material weakness contributed to the restatement of the financial statements for  fiscal 2005
and 2006, as discussed in Note 17 of the Notes to the Consolidated Financial  Statements, and
material post closing adjustments reflected in the financial statements as of and for fiscal 2007.
These adjustments resulted in changes to assets, liabilities, stockholders’ equity, revenues and
expenses.

2)

Inadequate and ineffective controls  over the accounting for transfers of customer  installment and
accounts receivables under receivable sale facilities

We did not have adequate design or operation of controls to provide reasonable assurance

that the amount or method of consolidation of new and outstanding installment and accounts
receivables was allowable and properly accounted for as a sale of assets or a secured  borrowing
under the terms of the applicable receivable sale facilities. Controls also did not operate to ensure
that only eligible assets were initially transferred under the receivable  sale  facilities. This weakness
contributed to the restatement of the financial statements for fiscal 2005 and 2006, as discussed in
Note 17 of the Notes to the Consolidated Financial Statements, and material post closing
adjustments reflected in the financial statements as of and for fiscal 2007. These adjustments
caused changes in collateralized receivables, retained interest in sold receivables, prepaid  expenses,
other assets, accrued expenses, secured borrowings,  gain or loss  on disposals  of  assets, general and
administrative expenses, interest income, interest expense, and currency  gains and losses on
retained assets which are reflected in the accompanying  financial statements.

3)

Inadequate and ineffective controls over income tax accounting and disclosure

We did not have adequate design or operation of controls to provide  reasonable assurance
that the accounting for income taxes and related disclosures were prepared in accordance with
GAAP. This material weakness contributed  to  the restatement  of  the financial statements for fiscal
2005 and 2006, as discussed in Note 17 of the Notes to the Consolidated Financial  Statements, and
material post closing adjustments reflected in the financial statements as of and for fiscal 2007.
These adjustments caused changes to income taxes payable, deferred income tax assets and
liabilities, valuation allowance, income tax provision, and disclosures of such amounts.

4)

Inadequate and ineffective controls over the  recognition of revenue

We did not have adequate design or operation of controls to provide reasonable assurance
that (a) non-routine revenue arrangements are properly documented and accounted for; (b) license
revenue as part of multiple-element service arrangements, where such services are bundled, is
properly accounted for under GAAP; (c) estimated total costs for fixed price services arrangements
are updated on a timely basis; (d) creditworthiness of customers is adequately assessed and
documented; and (e) the present value of license contracts with extended payment terms is
recorded using a discount rate appropriate for the customer. This material weakness contributed to
the restatement of the financial statements for fiscal 2005 and 2006, as discussed in Note 17 of the
Notes to the Consolidated Financial Statements, and material post closing adjustments reflected in

69

the financial statements as of and for fiscal 2007.  These adjustments caused  changes in revenue,
interest income, accounts receivable, unbilled services, and deferred revenue.

5)

Ineffective and inadequate controls over the accounts  receivable function

We did not have adequate design or operation of controls to provide  reasonable assurance
that accounts receivable ledgers were properly maintained and valuation adjustments were  properly
recognized. Specifically, our controls did not ensure that (a) accurate and complete information as
to our ability to collect outstanding installment and accounts receivables is  captured and used to
record sufficient provisions for doubtful accounts; (b) interest income on installment receivables is
appropriately classified within the statement of operations; (c) credits and adjustments for sales
and withholding taxes are properly recorded; and (d) professional  services  delivered  but  not  billed
are properly presented in the balance sheet. This material weakness contributed to the restatement
of the financial statements for fiscal 2005 and 2006, as discussed in Note 17 of the Notes to the
Consolidated Financial Statements, and material post closing adjustments reflected in the financial
statements as of and for fiscal 2007. These adjustments caused changes in the valuation of
accounts and installments receivable, unbilled receivables, accrued expenses, deferred revenue,
revenue, general and administrative expenses and interest income.

Deloitte & Touche LLP, our independent registered public  accounting  firm, has issued an attest report
on our assessment of our internal control over financial reporting. This  report appears  below.

Changes in Internal Control  Over Financial Reporting

For the first three quarters of the year  ended June 30,  2007, we reported within  the applicable

Form 10-Q material changes made to our internal control over financial  reporting (as defined in
Rules 13a-15(f) and 15d-15(f) under  the Exchange Act) intended to address our previously reported
material weaknesses. During the quarter ended June 30, 2007, no  additional changes were identified to
our internal control over financial reporting that materially affected, or were reasonably likely to
materially affect, our internal control over financial reporting except  for the  material weaknesses
related to the accounting for transfers of customer installments and accounts receivables under
receivable sale facilities and recognition of revenue discussed above.

Although the remedial measures implemented and reported  in prior  quarters  improved  our
internal control over financial reporting in certain respects, our processes and systems require  further
improvement and are dependent upon the training and effectiveness of a number  of  qualified finance
and accounting staff that were hired in the fiscal year. As discussed above, our management expects to
continue to develop our remediation plans and implement additional  changes to our internal control
over financial reporting during fiscal 2008 and possibly into fiscal 2009.

Remediation Plans

Management has identified the following measures to strengthen our internal control over financial

reporting and to address the material weaknesses described above. We began implementing certain of
these measures prior to the filing of this Form 10-K but changes made to our internal controls  have not
yet been in place for a sufficient time to have had a significant effect. We expect to continue to develop
our remediation plans and implement additional measures during our fiscal year 2008 and possibly into
fiscal 2009.

In order to improve controls over the periodic financial close process, we intend to:

• Complete the upgrade of our existing financial  applications, which  is designed  to  streamline the

capturing of relevant data, improve the general ledger and entity account level reporting
structures and enhance the information query and reporting capability for the consolidated
books worldwide;

70

• Complete the consolidation of financial operations  into three global  centers;

• Continue to assess training requirements and adequacy and expertise of the  finance and

accounting staff on a global basis;

• Further improve the periodic financial close process  through the use of a detailed  financial  close

plan and enhanced review of manual journal entries, account reconciliations, estimates and
judgments and consolidation schedules;

• Assess the adequacy of the systems  and  procedures used to track  and account for  stock-based

awards;

• Further simplify the legal entity structure; and

• Further enhance procedures to help ensure that  the proper accounting for all complex
non-routine transactions is researched, detailed in memoranda and  reviewed by senior
management prior to recording.

In order to improve controls over the accounting for transfers of customer installment and accounts

receivables under receivable sale facilities, we intend to:

• Enhance procedures, including increased  management  review and approval of  receivable

transfers under receivable sale facilities and development  of appropriate systems and reporting
mechanisms, to ensure that transactions are allowable and properly accounted for as a sale of
assets or secured borrowing under the terms of the receivable sale facilities;

• Enhance receivable reconciliation procedures to ensure that only valid receivables  are included

on internal reports used to identify receivables eligible for transfer; and,

• Improve reporting and review procedures between the company and  the  financial  institutions

who participate in the receivable sales facilities.

In order to improve controls over income tax accounting and disclosure, we intend  to:

• Enhance our policies and procedures for determining  and  documenting income tax  liabilities and

contingencies;

• Enhance our policies and procedures for determining,  documenting and calculating our tax

provisions in accordance with the applicable tax code and the determination of deferred income
tax assets and liabilities including stock based compensation, tax  credits,  net operating loss
carryforwards and limitations thereto as defined under section 382  of the Internal Revenue  Code
of 1986, as amended; and

• Increase the number of personnel or use of outside advisors with specialized corporate and

international tax expertise.

In order to improve controls over the recognition of revenue, we intend to:

• Increase the frequency, scope and tracking  of training on revenue recognition for our  sales and

services organizations, executive management, regional finance, accounting and operations
personnel;

• Hire additional personnel in regional finance and revenue accounting with expertise in software

revenue recognition;

• Enhance review procedures for  contracts containing both  license and service elements;

• Enhance the process used to determine the estimated discount  rate  for the  present  value of

license contracts with extended payment terms;

71

• Enhance contract review documentation and procedures to identify  and accurately account for

non-routine arrangements with customers;

• Revise the credit approval policy to include guidelines for the establishment and approval of
customer credit limits and further define procedures for the ongoing monitoring of customer
receivable balances;

• Improve procedures to identify and monitor customers who are approved  on a pre-payment

basis and ensure the underlying revenue transactions are accurately accounted  for; and

• Formalize and document a quarterly review of  estimated total  costs for fixed price professional

services projects and analyze significant variances to actual costs.

In order to improve controls over the accounts receivable function we intend  to:

• Enhance procedures for the review and  approval of customer credit memos and adjustments
including a monthly reconciliation of authorized amounts to actual credits and adjustments
recorded;

• Increase the level and frequency of review of professional services projects with unbilled  and

unearned balances to ensure that amounts recorded as unbilled services or deferred revenue are
valid and accurate and provisions for uncollectible amounts are sufficient;

• Increase the level and frequency of review of  past  due  accounts and  related installments in the

accounts receivable aging on a global basis;

• Assess training requirements and adequacy and expertise  of  the collections  and accounts

receivable staff on a global basis; and

• Assess the adequacy of the accounting  applications deployed  to  service accounts receivable

which have been sold.

If the remedial measures described above are insufficient to address  any of  the identified material

weaknesses, or additional deficiencies that may arise in the future,  material misstatements in our
interim or annual financial statements may occur in the future. We are currently  implementing an
enhanced controls environment intended to address the material  weaknesses in our internal  control
over financial reporting and to remedy the ineffectiveness of our disclosure controls and procedures.
While this implementation phase is underway, we are relying on extensive manual procedures, including
regular reviews, to assist us with meeting the objectives otherwise fulfilled by  an effective internal
control environment. Among other things, any unremediated material weaknesses could result in
material post-closing adjustments in future financial statements. Furthermore, any  such unremediated
material weaknesses could have the effects described in ‘‘Item 1A. Risk Factors—In preparing our
consolidated financial statements, we identified material weaknesses in our internal control  over
financial reporting, and our failure to remedy effectively the five material weaknesses identified as  of
June 30, 2007 could result in material misstatements in our financial statements’’ in  Part I  of  this
Form 10-K.

REPORT OF INDEPENDENT REGISTERED  PUBLIC  ACCOUNTING FIRM

To the Board of Directors and Stockholders  of
Aspen Technology, Inc.
Burlington, Massachusetts

We  have audited management’s assessment, included  in the accompanying Management’s Report

on Internal Control over Financial Reporting, that Aspen Technology, Inc. and subsidiaries (the
‘‘Company’’) did not maintain effective internal control over financial reporting as of June 30, 2007,
because of the effect of the material weaknesses identified in management’s assessment based on
criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission. The Company’s management is responsible for maintaining
effective internal control over financial reporting and for its assessment of the effectiveness of internal
control over financial reporting. Our responsibility is to express  an opinion on management’s
assessment and an opinion on the effectiveness of the Company’s internal control over  financial
reporting based on our audit.

We conducted our audit in accordance with the  standards of  the Public Company Accounting
Oversight Board (United States). Those standards require that we plan and perform the  audit to obtain
reasonable assurance about whether effective internal control over financial reporting was maintained
in all material respects. Our audit included obtaining  an understanding  of internal control over
financial reporting, evaluating management’s assessment, testing and evaluating the  design and
operating effectiveness of internal control, and performing such other procedures as we considered
necessary in the circumstances. We  believe that our audit provides a  reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed by, or under the

supervision of, the company’s principal executive and principal financial officers, or  persons performing
similar functions, and effected by the company’s board of directors, management, and other personnel
to provide reasonable assurance regarding the reliability of financial reporting and the preparation of
financial statements for external  purposes in accordance with  generally accepted accounting  principles.
A company’s internal control over financial reporting includes those policies and procedures that
(1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the
transactions and dispositions of the assets of the company; (2) provide reasonable assurance that
transactions are recorded as necessary to permit preparation of financial  statements  in accordance with
generally accepted accounting principles, and that receipts and expenditures of the company  are being
made only in accordance with authorizations of management and directors of the company; and
(3) provide reasonable assurance regarding prevention or timely detection of unauthorized  acquisition,
use, or disposition of the company’s assets  that could have a material effect on  the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the
possibility of collusion or improper management override of controls, material misstatements due to
error or fraud may not be prevented or detected on a timely basis. Also,  projections of any evaluation
of the effectiveness of the internal control over financial reporting to future periods are subject to the
risk that the controls may become inadequate because of changes in conditions, or that the degree of
compliance with the policies or procedures may deteriorate.

A material weakness is a deficiency, or combination of deficiencies, in internal control over
financial reporting, such that there is a reasonable possibility that a material misstatement of the
company’s annual or interim financial statements will not be prevented or detected on a timely basis.
The following material weaknesses have been identified and included in management’s assessment:

1.

Inadequate and ineffective controls over the periodic financial close process

The Company did not have adequate design or operation of controls that provided reasonable
assurance that financial statements could be prepared in accordance with accounting principles

73

generally accepted in the United States of America (‘‘GAAP’’). Specifically, the Company did not
have adequate controls and procedures with respect to the (a) accounting for complex  non-routine
transactions, including the accounting for transfers of installment and accounts receivable  as
discussed below; (b) sufficient personnel with an appropriate level of technical accounting
knowledge, experience, and training; (c) review of manual journal entries recorded; (d)  timely
preparation and review of period-end account analyses and timely disposition of  any required
adjustments; (e) proper consolidation and accounting for all intercompany activities including those
denominated in local currencies; and (f) timely reconciliation and recording of stock-based awards.
This material weakness contributed to the restatement of the Company’s financial statements for
the years ended June 30, 2005 and 2006, as discussed in Note 17 of the Notes to the Consolidated
Financial Statements, and material post closing adjustments reflected  in the Company’s financial
statements as of and for the year ended June 30, 2007. These adjustments resulted in changes to
assets, liabilities, stockholders’ equity, revenues and expenses. This  weakness  could continue to
materially impact the Company’s financial statements.

2.

Inadequate and ineffective controls over the accounting for transfers of customer installment  and
accounts receivables under receivable sale facilities

The Company did not have adequate design or operation of controls to provide reasonable
assurance that the amount or method of consolidation of new and outstanding installment and
accounts receivables was allowable and properly accounted for as a sale of assets or a secured
borrowing under the terms of the applicable receivable sale facilities. Controls also did not operate
to ensure that only eligible assets were initially transferred under the receivable sale facilities. This
weakness contributed to the restatement of the Company’s financial statements for the years ended
June 30, 2005 and 2006, as discussed in Note 17 of the Notes to the Consolidated Financial
Statements, and material post closing adjustments reflected in the Company’s financial statements
as of and for the year ended June 30, 2007. These adjustments caused changes in collateralized
receivables, retained interest in sold receivables, prepaid expenses, other assets, accrued  expenses,
secured borrowings, gain or loss on disposals of assets, general and administrative expenses,
interest income, interest expense, and currency gains and losses on  retained assets  which are
reflected in the accompanying financial statements. This weakness could continue to materially
impact the balances in the accounts previously mentioned.

3.

Inadequate and ineffective controls over income tax accounting and disclosure

The Company did not have adequate design or operation of controls to provide reasonable
assurance that the accounting for income taxes and related  disclosures were prepared in
accordance with GAAP. This material weakness contributed  to  the restatement  of  the Company’s
financial statements for the years ended June 30, 2005 and 2006, as discussed in Note 17 of  the
Notes to the Consolidated Financial Statements, and material post closing adjustments reflected in
the Company’s financial statements as of and for the year ended June 30, 2007. These adjustments
caused changes to income taxes payable, deferred income tax assets and liabilities, valuation
allowance, income tax provision, and disclosures of such amounts. This weakness could continue to
materially impact the balances in the accounts previously mentioned.

4.

Inadequate and ineffective controls over the recognition of revenue

The Company did not have adequate design or operation of controls to provide reasonable
assurance that (a) non-routine revenue arrangements are properly documented and accounted for;
(b) license revenue as part of multiple-element service arrangements, where such services are
bundled, is properly accounted for under GAAP; (c) estimated total costs for fixed price  services
arrangements are updated on a timely basis; (d) creditworthiness of customers is adequately
assessed and documented; and (e) the present value of license contracts with extended payment
terms is recorded using a discount rate appropriate for the customer. This material weakness

74

contributed to the restatement of the Company’s financial statements for the years ended June  30,
2005 and 2006, as discussed in Note 17 of the Notes to the  Consolidated  Financial  Statements, and
material post closing adjustments reflected in the Company’s financial  statements  as of  and for the
year ended June 30, 2007. These adjustments caused changes in revenue,  interest income, accounts
receivable, unbilled services, and deferred revenue. This weakness  could continue to materially
impact the balances in the accounts previously mentioned.

5.

Ineffective and inadequate controls over the accounts  receivable function

The Company did not have adequate design or operation of controls to provide reasonable
assurance that accounts receivable ledgers were properly maintained and valuation adjustments
were properly recognized. Specifically, the Company’s controls  did not ensure  that (a) accurate and
complete information as to the Company’s ability to collect outstanding installment and accounts
receivables is captured and used to record sufficient provisions for  doubtful accounts;  (b) interest
income on installment receivables is appropriately classified within the statement  of  operations;
(c) credits and adjustments for sales and withholding taxes are  properly recorded; and
(d) professional services delivered but not billed are properly  presented in the balance sheet. This
material weakness contributed to the restatement of the Company’s financial statements for the
years ended June 30, 2005 and 2006, as discussed in Note 17 of the Notes to the Consolidated
Financial Statements, and material post closing adjustments reflected in the Company’s financial
statements as of and for the year ended June 30, 2007. These adjustments caused changes in the
valuation of accounts and installments receivable, unbilled receivables, accrued expenses, deferred
revenue, revenue, general and administrative expenses and interest income. This weakness could
continue to materially impact the balances of all of the accounts previously mentioned.

These material weaknesses were considered in determining the nature,  timing, and extent  of audit

tests applied in our audit of the consolidated financial statements as of and for the year ended June 30,
2007 of the Company, and this report does not affect our report on such financial statements.

In our opinion, management’s assessment that the Company did not maintain effective  internal
control over financial reporting as of June 30, 2007, is fairly stated, in  all material respects, based on
the criteria established in Internal Control—Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission. Also in our opinion, because  of the effect of
the material weaknesses described above on the achievement of the objectives of  the control criteria,
the Company has not maintained effective internal control over financial reporting as of June 30,  2007,
based on the criteria established in Internal Control—Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission.

We  have also audited, in accordance  with the  standards of the Public Company Accounting
Oversight Board (United States), the consolidated financial statements as of and for the year ended
June 30, 2007, of the Company and our report dated April 11, 2008 expressed an unqualified opinion
on those financial statements and included an explanatory paragraph relating to the restatement of the
Company’s consolidated financial statements described in Note 17.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act requires our executive officers and  directors, and

persons who own more than 10% of a registered class of our equity securities, to file changes in
ownership on Form 4 or 5 with the SEC. These executive officers, directors and 10% stockholders are
also required by SEC rules to furnish us with copies of all Section 16(a) reports they file. Based solely
on our review of the copies of these forms, we believe that all Section 16(a) reports applicable to our
executive officers, directors and ten-percent stockholders with respect to reportable transactions during
fiscal 2007 were filed on a timely basis.

79

Code of Business Conduct and Ethics

We  have adopted a written code of business  conduct  and ethics that applies to our  directors,
officers and employees, including our principal executive officer, principal financial officer, principal
accounting officer or controller, and persons performing similar functions.  We have posted a copy of
the code in the corporate governance section of our website, www.aspentech.com. We intend to satisfy
disclosure requirements regarding amendments to, or waivers from, our code by  posting such
information on our website.

Audit Committee

Our board of directors has a separately designated standing audit committee in accordance  with
Section 3(a)(58)(A) of the Securities Exchange Act. The responsibilities of the  audit committee include:

• appointing, approving the compensation  of, and assessing  the independence of our independent

registered public accounting firm;

• overseeing the work of our independent  registered public accounting firm, including the receipt

and consideration of reports from such firm;

• reviewing and discussing our annual  and  quarterly financial statements  and related disclosures

with management and our independent registered public accounting firm;

• monitoring our internal control over financial reporting and our disclosure controls and
procedures, as well as the implementation of our code of business  conduct  and ethics;

• overseeing our internal audit function;

• discussing and assessing our risk management policies;

• establishing policies regarding hiring  employees from  our independent registered public

accounting firm and procedures for the receipt and retention of accounting-related complaints
and concerns;

• meeting independently with members of our internal auditing staff, independent registered

public accounting firm and management; and

• preparing the audit committee report required by SEC rules.

The current members of the audit committee are  Donald P. Casey, Gary E. Haroian and Joan C.

McArdle. The board of directors has determined that Mr. Haroian is an ‘‘audit committee financial
expert’’ as defined in Item 407(d)(5)(ii) of Regulation S-K and qualifies as ‘‘independent’’ under
applicable Nasdaq rules. The audit committee met 35 times during fiscal 2007, either in person or by

Item 11. Executive Compensation

Compensation Discussion and Analysis

The compensation committee of our board of directors oversees our executive compensation
program. In this role, the compensation committee is responsible for determining compensation of our
executive officers for each fiscal year.

Objectives and Philosophy of Our Executive Compensation Program

AspenTech has a total compensation philosophy designed  to provide compensation  that  is linked to

performance, competitive with other companies in the markets in which we compete, and perceived to

80

be fair and equitable, and that can be sustained in all business environments. The compensation
policies established by the compensation committee have been designed  to  link  executive compensation
to the attainment of specific performance goals and to align the interests of executive  officers with
those of our stockholders. The policies are also designed to allow us to attract and retain senior
executives critical to our long-term success by providing competitive compensation packages  and
recognizing and rewarding individual contributions, to ensure that executive compensation is  aligned
with corporate strategies and business objectives, and to promote the achievement of  key  strategic and
financial performance measures.

To achieve these objectives, the compensation committee  evaluates our  executive compensation

program with the goal of setting compensation at levels the compensation committee believes are
competitive with those of other companies in our industry and regions that compete with us for
executive talent. In addition, our executive compensation program ties a substantial portion of  each
executive’s overall compensation to key strategic, financial and operational goals  such as  growth and
penetration of customer base and financial and operational performance, as  measured by metrics such
as revenue and profitability. We also  provide a portion of our executive compensation in  the form of
stock options and restricted stock units that vest over time, which we believe helps to retain  our
executives and aligns their interests with those of our stockholders  by  allowing  them to  participate in
the longer term success of our company through stock price  appreciation.

In making compensation decisions, the compensation committee reviewed information on practices,

programs and compensation levels implemented by publicly traded software companies. This peer
group consists of companies the compensation committee believes are generally comparable  to  our
company and against which the compensation committee believes we compete for executive  talent. The
composition of the peer group is reviewed and updated periodically by the compensation committee.
The companies included in this peer group as of June 30, 2007 were:

Agile Software
Ansys
Epicor Software
i2 Technologies
Informatica
JDA Software
Lawson Software
Manhattan Associates
Mentor Graphics

Parametric Technology
Progress Software
QAD
TIBCO  Software
webMethods

For fiscal 2007, the compensation committee also reviewed an  analysis provided by Watson Wyatt
Worldwide, an independent compensation consultant, in determining the compensation package of our
chief executive officer.

We consider actual realized compensation  received in determining if  our compensation programs

are meeting their objectives. We do not typically reduce compensation plan targets because  of
compensation realized from prior awards, however, as we do not want to create a disincentive for
exceptional performance.

Components of Our Executive Compensation Program

Our executive compensation program includes the following elements:

• base salary;

• annual discretionary and performance-based cash  bonuses;

• stock options and restricted stock units;

81

• insurance, retirement and other employee benefits; and

• severance and change-of-control benefits.

We  have no formal or informal policy or  target for allocating compensation between long-term and

short-term compensation, between cash and non-cash compensation or among  the different forms of
non-cash compensation. Instead, the compensation committee exercises its judgment and discretion in
determining what it believes to be the appropriate level and mix of the various  compensation
components. The committee also has a practice of reviewing its recommendations with the full board
before making its final compensation determinations.

Base Salary

We  establish base salaries at competitive market rates to attract and retain  the caliber  of talent

necessary for our success. Base salary is used to recognize the performance, skills, knowledge,
experience and responsibilities required of all our employees, including  our executive officers. When
establishing base salaries of our executive officers for fiscal 2007 and 2008, the  compensation
committee considered the survey data of compensation in the peer group, as well as a  variety of other
factors, including the experience and performance of the executive, the scope of the executive’s
responsibility, and the base salary of the executive at his prior employment,  where applicable.
Generally, we believe that our executives’ base salaries should be targeted near the median of the
range of salaries for executives in similar positions at comparable companies.

The compensation committee reviews the base salaries of our executive officers  at least  annually,

and adjusts base salaries from time-to-time to realign salaries with market levels  after taking into
account individual responsibilities, performance and experience.

Annual Cash Bonus

We  have two annual incentive bonus plans for  our  executives: the Executive Annual Incentive
Bonus Plan, which we refer to below as the Executive Plan, and the Operations Executives Plan, which
we refer to as the Operations Plan. The participants in the Executive Plan consist of our  chief  executive
officer and the executives reporting directly to our chief executive officer, except for executives who
participate in the Operations Plan. Each of Mark E. Fusco, Bradley T. Miller, Manolis E.  Kotzabasakis,
C. Steven Pringle and Blair F. Wheeler, who constituted our ‘‘named  executive officers’’as  of June  30,
2007 as described below under ‘‘Summary Compensation,’’ participated  in the Executive  Plan for fiscal
2007, except for Mr. Kotzabasakis, who participated in the Operations Plan. Messrs. Fusco, Miller and
Wheeler will participate in the Executive Plan for fiscal 2008, and Messrs. Kotzabasakis and Pringle will
participate in the Operations Plan.

Executive Plan

Amounts earned under the executive bonus plan are payable in cash  and directly tied to

achievement of corporate financial targets and attainment of individual performance goals.

Amounts payable under the executive bonus plan are based in part on meeting corporate operating

income targets. The corporate operating income component, weighted at 30% to 70% for both fiscal
2007 and fiscal 2008, measures the extent to which we achieve a corporate operating income target
amount. For both fiscal 2007 and fiscal 2008, the Executive Plan includes  both a minimum  operating
income threshold of 80% of the target amount, which must be met in order for any bonus to be paid
under the Executive Plan, and a maximum operating income threshold, above which no additional
bonus would be earned. Amounts payable under the Executive Plan correspond to the applicable
executive’s base salary, with those with broader scope typically being compensated at a higher level.

82

The annual corporate operating income target is contained in the business plan adopted by the board
of directors. Bonuses attributable to the corporate operating income component are paid annually.

Amounts payable under the Executive Plan are also based in  part  on whether an executive met

specific performance goals. Individual objectives, weighted at 30% to 70% for  both  fiscal 2007 and
fiscal 2008, measured the extent to which an individual achieved performance objectives  established
specifically for that executive officer. The performance objectives were necessarily tied to the particular
functional responsibilities of the executive, and the executive’s performance in fulfilling those
responsibilities.

The compensation committee reviews with the board and approves  the individual performance
goals for each executive under the Executive Plan. The chief executive officer develops individual goals
for the executives reporting to him, subject to the compensation committee’s  review and approval. The
compensation committee establishes goals for the chief executive officer. We do not have a  general
policy regarding the adjustment of compensation following a restatement or  adjustment  of  our
performance measures. The threshold level for being awarded a bonus pursuant to the Executive Plan
can be characterized as demanding, while the maximum goal  contemplates compliance  with challenging
requirements.

Operations Plan

Amounts earned under the Operations Plan are payable in cash and directly tied  to achievement

of corporate financial targets and regional performance objectives.

Amounts payable under the Operations Plan are based in part on meeting  corporate operating
income targets. The corporate operating income component, which was weighted at  20% for fiscal 2007
and fiscal 2008, measures the extent to which we achieve a corporate operating income  target amount.
For both fiscal 2007 and fiscal 2008,  the plan  includes both a minimum  operating income threshold of
80% of the target amount, which was required to be met in order for any bonus to be paid under the
Operations Plan, and a maximum operating income threshold, above which  no additional bonus would
be earned. Bonuses attributable to the corporate operating  income  component  are paid annually.

The regional performance component, which was weighted at 75% for both fiscal 2007 and fiscal
2008, measures the extent to which we achieved performance  objectives for the region or regions for
which the executive is responsible. Mr. Kotzabasakis had oversight  responsibility for all  regions in fiscal
2007, including responsibility for global accounts. Bonuses attributable to the regional performance
component are paid as quarterly commissions based on quarterly  regional financial results.

Amounts payable under the Operations Plan are also based in part on  whether  an individual met
specific performance goals. Individual objectives, weighted at 5% for both fiscal 2007 and fiscal 2008,
measured the extent to which an individual achieved performance objectives established specifically for
that executive officer. Payments based on this component were capped at the executive officers’
respective target bonus amounts. The performance objectives are necessarily tied to the  particular
functional responsibilities of the individual and his performance in fulfilling those responsibilities.

The compensation committee approves the performance goals for each executive, the weighting of

various goals for each executive, and the formula for determining potential bonus amounts based on
achievement of those goals. Our chief executive officer was responsible for developing, and assessing
compliance with, the individual performance goals for each executive participating in the Operations
Plan for fiscal 2007. In fiscal 2008, our chief executive officer and the executive vice president for field
operations are responsible for developing, and assessing compliance with, the individual performance
goals for each executive participating in the Operations Plan. The threshold level for being awarded a
bonus pursuant to the Operations Plan can be characterized as demanding, while the maximum goal
contemplates compliance with challenging requirements.

83

Stock Options and Restricted Stock Units

Our equity award program is the primary vehicle for offering long-term  incentives to our
executives. We believe that equity grants help to align the interests of our executives and our
stockholders, provide our executives with a strong link to our long-term performance and create  an
ownership culture. In addition, the vesting feature of our equity grants should further our goal of
executive retention by providing an incentive to an executive to remain in our employ during the
vesting period. In determining the size of equity grants to our executives, our compensation committee
considers comparative share ownership of executives in our compensation  peer group, our  company-
level performance, the individual executive’s performance, the amount of equity previously awarded to
the executive, the vesting status of the previous awards and the recommendations of  the  chief executive
officer.

We  typically make an initial equity award of stock  options to new executives and an annual equity
program grant as part of our overall compensation program. All grants of options and restricted stock
units to our executives are approved by the compensation committee.

Our equity awards typically have taken the form of stock  options and restricted stock units. The

compensation committee reviews all components of an executive’s compensation when  determining
annual equity awards to ensure that the executive’s total compensation conforms to our overall
philosophy and objectives.

We set the exercise price of all stock  option  grants to equal  the prior day’s closing price of our

common stock. Typically, the stock options we grant to our executives vest pro  rata over the  first
sixteen quarters of a ten-year option term. Vesting and exercise rights cease shortly  after termination of
employment except in the case of death or disability. Prior to the exercise of an option, the holder has
no rights as a stockholder with respect to the shares subject to such option, including voting  rights and
the right to receive dividends or dividend equivalents.

In October 2006, the compensation committee approved grants to named executive officers of
stock options having an exercise price of $10.42 per share of common stock and vesting in sixteen
quarterly installments, and restricted stock units that would vest,  subject to our achieving specified
performance goals in the fiscal year ending June 30, 2007, as to 25% upon  announcement of our
earnings for fiscal 2007 with the balance vesting in 12 equal quarterly installments thereafter. In
approving these grants, the compensation committee considered each named executive officer’s level of
responsibility within our company, the individual performance of the officer  and competitive industry
practice, as indicated by market data for companies that the compensation committee identified as
being comparable. In accordance with their terms, 25% of the restricted stock units vested in
September 2007, and additional units vested in October 2007 and January 2008.

Stock awards to our executives are typically  granted annually in conjunction  with the  review of
their individual performance. Going forward, the committee  has decided to make the annual program
grant contemporaneously with all other compensation changes for the year. This review typically  takes
place at the regularly scheduled meeting of the compensation committee held in the fourth quarter of
each fiscal year. We have had a practice not to award  program  grants or grants to officers during
blackout periods.

We  do not have any equity ownership guidelines  for our  executives.

Benefits and Other Compensation

We  maintain broad-based benefits that are  provided to all employees, including health and dental
insurance, life and disability insurance and a 401(k) plan. Executives are eligible to participate in all of
our employee benefit plans, in each case on the same basis as other employees. Our named executive
officers are not entitled to benefits that are not otherwise available to all employees.

84

Severance and Change-in-Control Benefits

Pursuant to executive retention agreements we have entered into with each of our named  executive

officers and to the provisions of our option agreements, those executives are entitled to specified
benefits in the event of the termination of their employment under specified circumstances, including
termination following a change in control of our company. We have provided more detailed
information about these benefits, along with estimates of their value under various circumstances,
under the caption ‘‘Potential Payments Upon Termination or Change in  Control’’ below.

We believe these agreements assist in  maintaining a competitive  position in terms of attracting and

retaining key executives. The agreements also support decision-making  that  is in  the best interests of
our stockholders, and enable our executives to focus on company priorities. We believe that our
severance and change in control benefits are generally in line with prevalent peer practice with respect
to severance packages offered to executives.

Except with respect to our chief executive officer, our practice in the case of change-of-control

benefits under the executive retention agreements has been to structure these as ‘‘double trigger’’
benefits. In other words, the change in control does not itself trigger benefits; rather,  benefits are  paid
only if the employment of the executive is terminated under the circumstances described below during
a specified period after the change in control. We believe a ‘‘double trigger’’  benefit maximizes
shareholder value because it prevents an unintended windfall to executives  in the event  of a friendly
change in control, while still providing them appropriate incentives to cooperate in negotiating any
change in control in which they believe they may lose their jobs.

Role of Executive Officers in the Compensation Process

Our senior vice president, human resources confers with the chief executive officer  and the
compensation committee to provide a market perspective on the competitive landscape and needs of
the business and compensation levels in the peer group and relevant market surveys.

Our chief executive officer provides the compensation committee with his perspective on the

performance of other executive officers. Based on his judgment and experience, our chief executive
officer recommends specific compensation amounts and awards for the other  executive officers, and the
compensation committee considers those recommendations and makes the ultimate decision.

Our chief executive officer also provides the compensation committee  with  a self-assessment of his

performance. The compensation committee independently establishes the compensation of the chief
executive officer, who is not present during discussions where his compensation is established.

Tax and Accounting Considerations

Section 162(m) of the Internal Revenue Code generally disallows a tax deduction to a publicly
traded company for certain compensation in excess of $1,000,000 paid to our chief executive officer and
our four other most highly compensated executive officers. Qualifying performance-based compensation
is not subject to the deduction limitation if specified requirements are met.

We  periodically review the potential consequences of Section 162(m), and we  generally intend to

structure the performance-based portion of our executive compensation, where feasible, to comply with
exemptions in Section 162(m) so that the compensation remains tax deductible to us. The
compensation committee in its judgment may, however, authorize compensation payments that do not
comply with the exemptions in Section 162(m) when it believes that such payments are appropriate to
attract and retain executive talent.

85

Potential Payments Upon Termination  or  Change in Control

On December 7, 2004, we entered into an  employment agreement with  Mark E.  Fusco, pursuant

to which Mr. Fusco agreed to serve as our President and Chief Executive Officer. Under  this
agreement, in the event of termination of Mr. Fusco’s employment (other than for  the reasons  set forth
below), including termination of his employment after a change in control (as defined  below) or
termination of employment by Mr. Fusco for ‘‘good reason’’ (which includes  constructive termination,
relocation, or reduction in salary or benefits), Mr. Fusco will be entitled to  a lump sum severance
payment equal to two times the sum of:

• the amount of Mr. Fusco’s annual base  salary in effect  immediately prior to notice of

termination (or in the event of termination after a change in control, then the amount of his
annual base salary in effect immediately prior to the change in control, if higher); and

• the amount of the average of the annual bonuses paid  to Mr. Fusco for the  three years (or the
number of years employed, if less) immediately preceding  the notice  of termination (or in the
event of termination after a change in control, then the amount of the average annual bonuses
paid to Mr. Fusco for the three years (or the number of years employed, if less) immediately
prior to the change in control, if higher) or the occurrence of a change in control, as the case
may be.

In addition, in lieu of any further life, disability, and accident insurance benefits otherwise due to
Mr. Fusco following his termination (other than for  the reasons set  forth below), including termination
after a change in control, we will pay Mr. Fusco a lump sum amount equal to the estimated cost (as
determined in good faith by us) to Mr. Fusco of providing such benefits, to the extent that Mr.  Fusco is
eligible to receive such benefits immediately prior to notice of termination,  for  a period of two years
commencing on the date of termination. We will also pay all health insurance due  to  Mr. Fusco for  a
period of two years commencing on the date of termination.

Mr. Fusco’s employment agreement provides that the payments received by  him relating to

termination of his employment will be increased in the event that these payments would subject him to
excise tax as a parachute payment under Section 4999 of the Internal Revenue Code. The increase
would be equal to an amount necessary for Mr. Fusco to receive, after payment of such tax,  cash in an
amount equal to the amount he would have received in the absence of such tax. However, the
increased payment will not be made if the total severance payment, if so increased, would  not  exceed
110% of the highest amount that could be paid without causing an imposition of the excise tax. In that
event, in lieu of an increased payment, the total severance payment  will be reduced to such reduced
amount. We have indemnified Mr. Fusco for the  amount  of  any penalty applicable to any payments
Mr. Fusco receives from us as a result of his termination that  are imposed by Section 409A of the
Internal Revenue Code.

However, in the event that Mr. Fusco’s employment is terminated for  one  or more of the  following

reasons, then Mr. Fusco will not be entitled to the severance payments described  above:

• by us for ‘‘cause’’ (as defined below);

• by reason of Mr. Fusco’s death or  disability;

• by Mr. Fusco without good reason (unless such resignation occurs within six months following  a

change in control); or

• after Mr. Fusco shall have attained age 70.

Under the terms of Mr. Fusco’s employment agreement, in the event of  a ‘‘potential change in

control’’ (as defined below), Mr. Fusco agrees to remain in our employment  until the earliest of:

• three months after the date of such  potential change in control;

86

• the date of a change in control;

• the date of termination by Mr. Fusco of his  employment for good  reason or by reason of death

or retirement; and

• our termination of Mr. Fusco’s employment  for  any reason.

For the purposes of Mr. Fusco’s employment  agreement, ‘‘cause’’ for our terminating Mr. Fusco

means:

• the willful and continued failure by Mr. Fusco to substantially perform  his  duties after written

demand by the board;

• willful engagement by Mr. Fusco in  gross misconduct  materially injurious  to  us; or

• a plea by Mr. Fusco of guilty or no  contest to a  felony charge.

For the purposes of Mr. Fusco’s employment  agreement, a  ‘‘change  in control’’ is  deemed to have

occurred if any of the following conditions shall have been satisfied:

• continuing directors cease to constitute  more  than two-thirds of the membership of the board;

• any person or entity acquires, directly or indirectly, beneficial  ownership of 50% or  more of the

combined voting power of our then outstanding voting securities;

• a change in control occurs  of a  nature that  we would be required  to  report on a current report
on Form 8-K or pursuant to Item 6(e) of Schedule 14A  of Regulation 14A or any similar  item,
schedule or form under the Securities Exchange Act, as in effect at the time of the  change,
whether or not we are then subject to such reporting requirement, including our merger or
consolidation with any other corporation, other than:

• a merger or consolidation where (1) our voting securities  outstanding immediately prior to such
transaction continue to represent 51% or more of the combined voting power  of  the voting
securities of the surviving or resulting entity outstanding immediately after such transaction, and
(2) our directors immediately prior to such merger or consolidation continue to constitute  more
than two-thirds of the membership of the board of directors of the surviving  or combined  entity
following such transaction; or

• a merger or consolidation effected to implement our recapitalization of  (or similar transaction)
in which no person or entity acquires 25% or more of the combined voting power  of our then
outstanding securities; or

• our stockholders approve a plan of complete liquidation or an agreement for the sale or

disposition of all or substantially all of our assets (or any transaction having a similar effect).

For the purposes of Mr. Fusco’s employment agreement,  a  ‘‘potential change  in control’’ is  deemed

to have occurred if any of the following conditions shall have been satisfied:

• we enter into an agreement, the consummation of which  would result in the occurrence of a

change in control;

• we or anyone else publicly announces an  intention to take or to consider taking actions which, if

consummated, would constitute a change in control;

• any person or entity becomes the beneficial owner, directly or indirectly,  of 15% or more  of the
combined voting power of our then outstanding securities (entitled to vote generally for the
election of directors); or

• the board adopts a resolution to the effect  that, for  purposes of Mr. Fusco’s employment

agreement, a ‘‘potential change in control’’ has occurred.

87

On October 28, 2005, we entered into an amendment to our employment agreement with

Mr. Fusco. This amendment provides that in the  event Mr.  Fusco  becomes entitled,  on the  terms and
conditions set forth in the employment agreement, to receive a severance payment upon termination of
his employment, such a payment must be made within 30 days after the Date of Termination (as
defined in the employment agreement). Notwithstanding the foregoing, if the  severance payment will
constitute ‘‘nonqualified deferred compensation’’ subject to the provisions of Section 409A of the
Internal Revenue Code, then the payment instead will be due within 15 days after the earlier of  (i) the
expiration of six months and one day following the Date of Termination or (ii) Mr. Fusco’s death
following the Date of Termination.

On September 26, 2006, we entered into executive retention agreements with the following

executive officers: Bradley T. Miller, our Senior Vice President and Chief Financial Officer; Manolis E.
Kotzabasakis, our Senior Vice President, Sales and Strategy; C. Steven Pringle,  our Senior  Vice
President, aspenONE; and Blair F. Wheeler, our Senior Vice President, Marketing,  each of whom we
refer to as a specified executive.

Pursuant to the terms of each executive retention agreement, if the specified executive’s

employment is terminated prior to a change in control without cause, the specified executive will be
entitled to the following:

• payment of an amount equal to the specified  executive’s  annual  base  salary  then in effect,

payable over twelve months;

• payment of an amount equal to the specified  executive’s  total target bonus  for the  fiscal  year,
pro-rated for the portion of the fiscal year elapsed prior to termination, payable  in one lump
sum;

• payment of an amount equal to the cost to the  specified executive of providing life, disability

and accident insurance benefits, payable in one lump sum, for a period of one year;  and

• continuation of medical, dental and vision insurance  coverage to which the  specified executive

was entitled prior to termination for a period of one year.

In the event the specified executive’s employment is terminated within twelve months  following  a

change in control without cause or by the specified executive for good reason (which  includes
constructive termination, relocation, a reduction in salary or benefits, or our breach of any employment
agreement with the specified executive or a failure to pay benefits when due), then the specified
executive shall be entitled to the following:

• payment of an amount equal to the sum of  the specified  executive’s  annual base salary  then in
effect and the specified executive’s target bonus for the then-current fiscal year, payable  in a
single installment;

• payment of an amount equal to the cost  to  the  specified executive of providing life, disability
and accident insurance benefits, payable in a single installment, for a period of one year;

• continuation of medical, dental and vision insurance coverage to which the  specified executive

was entitled prior to termination for a period of one year; and

• full vesting of (a) all of the specified executive’s options  to purchase shares of our stock, which
options may be exercised by the specified executive for a period of twelve months following the
date of termination and (b) all restricted stock and restricted stock units then held by the
specified executive.

Each executive retention agreement provides that the total payments received by the specified
executive relating to termination of his employment will be reduced to an amount equal to the highest
amount that could be paid to the specified executive without subjecting such payment to excise tax as a

88

parachute payment under Section 409A of the Internal Revenue Code, provided that no reduction shall
be made if the amount by which these payments are reduced exceeds 110% of the value of any
additional taxes that the specified executive would incur if the total payments  were not reduced.

For the purposes of each agreement:

• ‘‘change in control’’ means (a) the acquisition  of 50%  or more of either the  then-outstanding
shares of our common stock or the combined voting power of our then-outstanding securities,
(b) such time as the members of the board immediately prior to the change in  control do not
continue to constitute the majority of our directors following the change  in control, (c) the
consummation of a merger, consolidation, reorganization, recapitalization or share exchange
involving our company, unless the transaction would not result  in a  change in ownership  of  50%
or more of both our then-outstanding common stock and the combined voting power of our
then-outstanding securities; or (d) our liquidation or dissolution;

• ‘‘cause’’ means (a) the willful and continued failure by a specified executive to substantially

perform his duties for us after delivery by the board of a written demand for performance (other
than any such failure resulting from his incapacity due  to  physical or  mental illness or any such
actual or anticipated failure after his issuance of a notice of termination for good reason)  and a
failure by the specified executive to cure the performance failure  within 30  days or (b) the
willful engaging by the specified executive in gross misconduct  that  is demonstrably and
materially injurious to us; and

• ‘‘good reason’’ means constructive termination of the specified executive, relocation, a reduction
in the specified executive’s salary or benefits, our breach of any  employment agreement  with the
specified executive or our failure to pay benefits when due.

Each executive retention agreement terminates on the earliest to occur of (a) July  31, 2008, (b) the

first anniversary of a change in control, and (c) our payment of all  amounts  due to the specified
executive following a change in control. Each agreement is subject to automatic renewal on August 1 of
each year, unless we give notice of termination at least seven days prior to the renewal date.

89

The following table sets forth estimated compensation that would  have been payable to each of

these officers as severance or upon a change in control of our company under three  alternative

(1) Consists of performance-based cash incentive bonus awards  under the Executive  Annual  Incentive
Bonus Plan and Operations Executive Plan. Actual amounts awards are set forth in the summary
compensation table above.

(2) Represents the compensation expense we  recognized in fiscal 2007  related to the applicable share-
based award pursuant to SFAS 123(R). Assumptions used in the calculations  for these amounts are
included in Note 9 of the Notes to the Consolidated Financial Statements.

As discussed in ‘‘Compensation Discussion and Analysis’’ above, each of the named executive

officers other than Mr. Kotzabasakis participated in the Executive Plan. Amounts payable under the
Executive Plan are based in part on meeting corporate operating income targets. The corporate
operating income component, weighted at 30% to 70% for both fiscal 2007 and fiscal 2008, measures
the extent to which we achieve a corporate operating income target amount. For both fiscal 2007 and
fiscal 2008, the Executive Plan includes both a minimum operating income threshold of 80% of the
target amount, which must be met in order for any bonus to be paid under the Executive Plan, and a
maximum operating income threshold, above which no additional bonus would be earned. Amounts
payable under the Executive Plan correspond to the applicable executive’s base salary, with those with

93

broader scope typically being compensated at a higher level. The annual corporate operating income
target is contained in the business plan adopted by the board of directors. Bonuses attributable to the
corporate operating income component are paid annually.

Amounts payable under the Executive Plan are also based  in  part  on whether an individual met

specific performance goals. Individual objectives, weighted at 30% to 70% for both fiscal 2007  and
fiscal 2008, measured the extent to which an individual achieved performance  objectives established
specifically for that executive officer. The performance objectives are necessarily tied to the  particular
functional responsibilities of the individual, and his performance in fulfilling those responsibilities.

Mr. Kotzabasakis participated in the Operations Plan. Amounts payable under the Operations Plan

are based in part on meeting corporate operating income targets. The corporate operating income
component, which was weighted at 20% for fiscal 2007 and fiscal 2008, measures the extent to which
we achieve a corporate operating income target amount. For both fiscal 2007 and fiscal 2008, the plan
includes both a minimum operating income  threshold of 80% of the target  amount,  which was  required
to be met in order for any bonus to be paid under the Operations Plan, and a maximum operating
income threshold, above which no additional bonus would be earned. Bonuses attributable to the
corporate operating income component are paid annually.

The regional performance component, which was weighted at 75% for both fiscal 2007 and fiscal

2008, measures the extent to which we achieved performance  objectives for the region(s) for which  the
executive is responsible. Mr. Kotzabasakis had oversight  responsibility for all  regions in fiscal 2007,
including responsibility for global accounts. Bonuses attributable to the regional performance
component are paid as quarterly commissions based on quarterly  regional or consolidated financial
results.

Amounts payable under the Operations Plan are also based in part on  whether  an individual met
specific performance goals. Individual objectives, weighted at 5% for both fiscal 2007 and fiscal 2008,
measured the extent to which an individual achieved performance objectives established specifically for
that executive officer. Payments based on this component were capped at the executive officers’
respective target bonus amounts. The performance objectives are necessarily tied to the  particular
functional responsibilities of the individual and his performance in fulfilling those responsibilities.

In October 2006, the compensation committee approved grants to named executive officers of  stock

options having an exercise price of $10.42 per share of common stock and vesting in  sixteen  quarterly
installments, and  restricted stock units that would vest, subject to our achieving specified  performance
goals in the fiscal year ending June 30, 2007, as to 25% upon announcement of our earnings  for  fiscal
2007 with the balance vesting in 12 equal quarterly installments thereafter. In  approving these grants, the
compensation committee considered each named executive officer’s level of  responsibility within our
company, the individual performance of the officer and competitive industry  practice,  as indicated by
market data for  companies that the compensation committee identified as being comparable. In
September 2007,  25% of the restricted stock units vested in accordance with  their terms.

As also discussed in ‘‘Compensation Discussion and Analysis’’ above, each of the named executive

officers was issued annual equity incentive grants under the 2005 Stock Incentive Plan, 2002 Stock
Option Plan and the 2001 Stock Option Plan. Each of the executive officers was granted stock options
with an exercise price equal to the closing price of our common stock on the trading day immediately
preceding the grant date of November 17, 2006. Each of these options vests quarterly over a four-year
period, beginning on December 29, 2006. In addition, on November 17, 2006, each of the named
executive officers was issued restricted stock units, each of which represents a contingent right to
receive one share of our common stock. Restricted stock units do not have a purchase or  exercise
price. Each restricted stock unit shall vest, subject to our achieving profitability in fiscal 2007, as to
25% upon public announcement of our operating results for fiscal 2007 with the balance vesting in 12
equal quarterly installments thereafter. In light of the delay in the public announcement of our fiscal

94

2007 operating results arising in connection with a restatement of our financial statements, the
compensation committee determined in September 2007 that the fiscal 2007 profitability threshold for
the restricted stock units had been met and waived the requirement that the fiscal 2007 operating
results be publicly announced for purposes of the vesting  of  the restricted stock units.

The compensation committee, in determining the number of shares issuable upon exercise of

options and the number of restricted stock units, considered each named executive officer’s  level of
responsibility within our company, the individual performance of the officer  and competitive industry
practice, as indicated by market data for companies that the compensation committee identified as
being comparable.

Financial Statements. The following are the aggregate number of  option awards
outstanding held by each of our non-employee directors as of June 30, 2007: Mr. Casey,
48,000; Mr. Haroian, 48,000; Mr. Jennings, 100,298; Ms. McArdle, 117,298; Mr. McKenna,
24,000; Mr. Pehl, 60,000; and Mr. Pike, 2,000.

(2) Mr.  Pike served on the board from  January 2006  to  September 2006.

In fiscal 2007, we paid our non-employee directors an annual fee of $25,000 for their services as
directors. In addition, we paid annual retainers of $15,000 to the chairman and  to  the chair of the audit
committee, and annual retainers of $7,500 to the chairs of the compensation committee and the
nominating and corporate governance committee. All annual retainers are payable in quarterly
installments.

In fiscal 2007, we also paid each director $2,500 for participation in our quarterly board meetings
and $2,000 for participation in all other board of directors or committee meetings of at least one hour
duration.

In fiscal 2008, we have increased the retainer for the chairman, the audit committee chair  and the

compensation committee chair to $75,000, $30,000 and $15,000, respectively, and provided a retainer
for other audit and compensation committee members of $20,000 and $7,500, respectively.

We  grant to each non-employee director,  upon his or her initial election  to  the board,  an option  to
purchase 24,000 shares of our common stock at the fair market value of  our  common  stock on the  date
of grant, provided such non-employee director was not, within the twelve months preceding his or her
election as a director, an officer or employee of our company or any of our subsidiaries. Any such
option vests quarterly over a three-year period, beginning on the last day of the calendar quarter
following the grant date.

98

Beginning with the first annual meeting following a non-employee director’s election to the board
and on a quarterly basis thereafter, we grant each non-employee director an option to purchase 3,000
shares of our common stock. Each option is fully exercisable at the time of grant and has an exercise
price equal to the fair market value of our common stock at the time of grant. Options granted  to
non-employee directors have terms of ten years.

Item 12. Security Ownership of Certain Beneficial Owners  and  Management  and Related Stockholder

Matters

See ‘‘Securities Authorized for Issuance Under Equity Compensation Plans’’ under ‘‘Item 5.
Market for Registrant’s Common Equity, Related  Stockholder Matters and Issuer Purchases of Equity
Securities’’ in Part II of this Form 10-K.

The following table sets forth certain information as of November 1,  2007, with  respect to the

beneficial ownership of our common stock:

• each person or group that we know to be the beneficial owner of more than 5% of  the

outstanding shares of any class of our voting securities;

• each of the named executive officers;

• each of our directors; and

• all of our current executive officers and directors as a group.

A total of 89,429,464 shares of common stock were outstanding as of November 1,  2007.

Unless otherwise noted, each person identified possesses sole voting and investment power with

respect to the shares listed, subject to community property laws where  applicable. Shares under
‘‘Common Stock—Right to Acquire’’ include shares subject to options or warrants that were  vested as
of November 1, 2007 or will vest within 60 days of November 1, 2007. Shares not outstanding  but
deemed beneficially owned by virtue of the right of a person to acquire those  shares are treated as
outstanding only for purposes of determining the number and percent of shares  of  common stock
owned by such person or group. Percentages under ‘‘Common  Stock—Percent  of Voting Power’’
represent beneficial rights to vote with respect to matters on which holders  of  common stock generally
are entitled to vote, as of November 1, 2007, and are based on (a) the number of outstanding shares of
common stock beneficially owned by that person and (b) the number of shares subject to options or
warrants held by that person that were exercisable on, or within 60 days after, November 1, 2007.  In
calculating percentages under ‘‘Common Stock—Percent of Voting Power,’’ the  total number  of votes
entitled to be cast as of November 1, 2007 consisted of (a) 89,429,464 votes, which is the total  votes  to
which the holders of outstanding shares of common stock are entitled, plus (b) for  an identified person,
a number of votes equal to the number of shares issuable upon conversion or subject to options or
warrants that were exercisable by such person on, or within 60 days after, November 1,  2007.

Communications III-C Limited Partnership, Digital Media & Communications III-D  C.V.,  Digital
Media & Communications III-E C.V., and Advent Energy II Limited  Partnership.  We refer to these
entities as the Advent funds.

The shares reflected as beneficially owned by Waddell & Reed Financial, Inc. (‘‘WDR’’) are
beneficially owned by one or more open-end investment companies or other managed accounts which
are advised or sub-advised by Ivy Investment Management Company (‘‘IICO’’), an  investment advisory
subsidiary of WDR or Waddell  & Reed Investment Management  Company (‘‘WRIMCO’’), an
investment advisory subsidiary of Waddell & Reed, Inc. (‘‘WRI’’),  based upon information provided in
a Schedule 13G filed by WDR with the SEC on February 9, 2007. WRI is a broker-dealer  and
underwriting subsidiary of Waddell & Reed Financial Services, Inc., a  parent holding company
(‘‘WRFSI’’). In turn, WRFSI is a subsidiary of WDR, a publicly traded company.  The  investment
advisory contracts grant IICO and WRIMCO all investment and/or voting power over securities owned
by such advisory clients. The investment sub-advisory contracts grant IICO  and WRIMCO investment
power over securities owned by such sub-advisory clients and, in  most cases, voting power. Any
investment restriction of a sub-advisory contract does not restrict investment discretion or  power in a
material manner.

The number of shares reflected as beneficially owned by Alydar Partners,  LLC is  based upon

information provided in a Schedule 13G filed by Alydar with the SEC on February 16, 2007.

in his capacity as a limited partner of Advent  Partners II Limited Partnership. Mr.  Pehl disclaims
beneficial ownership of the shares except to the extent of his pecuniary interest therein.

The shares of common stock reflected as owned by David M. McKenna are indirectly  beneficially

owned in his capacity as a limited partner of Advent Partners GPE IV Limited Partnership.
Mr. McKenna disclaims beneficial ownership of the shares except to the extent of his  pecuniary interest
therein.

Item 13. Certain Relationships and Related Transactions

Board Determination of Independence

Our board of directors uses the definition of independence established by The NASDAQ Stock

Market. Under applicable Nasdaq rules, a director qualifies as an ‘‘independent director’’  if, in the
opinion of the board of directors, he or she does not have a relationship that would interfere with the
exercise of independent judgment in carrying out the responsibilities of a director. The board  of
directors has determined that Donald P. Casey, Gary E. Haroian, Stephen M.  Jennings  and Joan C.
McArdle do not have any relationship that would interfere with the exercise of independent  judgment
in carrying out the responsibilities of a director of Aspen Technology, Inc., and that each of  these
directors therefore is an ‘‘independent director’’ as defined in Rule  4200(a)(15) of the Nasdaq
Marketplace Rules.

provided in connection with statutory and regulatory filings or engagements.

‘‘Audit-Related Fees’’ consist of fees  for assurance and related services that were reasonably  related

to the performance of the audit and review of our financial statements and  that are not reported as
audit fees.

‘‘Tax Fees’’ consist of fees for tax compliance, tax advice and tax planning services.  None of the tax
fees billed in fiscal 2006 or 2007 were provided under the de minimis exception to the audit committee
pre-approval requirements.

Pre-Approval Policies and Procedures

The audit committee has adopted policies and procedures relating to the approval of  all  audit and
non-audit services that are  to be performed by our independent registered  public accounting firm. This
policy generally provides that we will not engage our independent  registered public accounting firm to
render audit or non-audit services unless the service is specifically  approved in  advance by the audit
committee, except that de minimis non-audit services may instead be approved in accordance with
applicable SEC rules.

REPORT OF INDEPENDENT REGISTERED  PUBLIC  ACCOUNTING FIRM

To the Board of Directors and Stockholders  of
Aspen Technology, Inc.
Burlington, Massachusetts

We  have audited the accompanying consolidated balance sheets of Aspen  Technology,  Inc. and
subsidiaries (the ‘‘Company’’) as of June 30, 2006 and 2007, and the related consolidated statements  of
operations, stockholders’ equity (deficit) and comprehensive income (loss),  and  cash flows for each of
the three years in the period ended June 30, 2007. These financial statements are the responsibility of
the Company’s management. Our responsibility is to express an opinion on these financial  statements
based on our audits.

We conducted our audits in accordance with the standards  of  the Public Company Accounting
Oversight Board (United States). Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and disclosures  in the
financial statements. An audit also includes assessing the accounting principles used and  significant
estimates made by management, as well as evaluating the  overall financial statement presentation. We
believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the

financial position of Aspen Technology, Inc. and subsidiaries as of June 30, 2006  and  2007,  and the
results of their operations and their cash flows for each of the three years in the period  ended June 30,
2007, in conformity with accounting principles generally accepted in the United States of America.

As discussed in Note 9 to the consolidated financial statements,  effective July 1,  2005 the Company

changed its method of accounting for stock-based compensation upon adoption of Statement  of
Financial Accounting Standards No. 123(R) ‘‘Share-Based  Payment.’’

As discussed in Note 17, the accompanying consolidated  financial statements for fiscal 2005  and

2006 have been restated.

We  have also audited, in accordance  with the  standards of the Public Company Accounting
Oversight Board (United States), the effectiveness of the Company’s internal control over financial
reporting as of June 30, 2007, based on criteria established in Internal Control—Integrated Framework
issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report
dated April 11, 2008 expressed an unqualified opinion on  management’s assessment  of the effectiveness
of the Company’s internal control over financial reporting and an adverse  opinion on the  effectiveness
of the Company’s internal control over financial reporting because of material weaknesses.

ASPEN TECHNOLOGY, INC. AND  SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) Operations

Aspen Technology, Inc. (the Company) and its subsidiaries  are a  leading supplier of integrated

software and services to the process industries, which consist  of oil and gas,  petroleum, chemicals,
pharmaceutical and other industries that manufacture and produce products from a  chemical  process.
The Company develops software to design, operate, manage and optimize its customers’ key business
processes.

(2) Significant Accounting Policies

(a) Principles of Consolidation

The accompanying consolidated financial statements include the  accounts of the Company and its

wholly owned subsidiaries. All intercompany balances and transactions  have been eliminated in
consolidation.

(b) Management Estimates

The preparation of financial statements in conformity with accounting principles  generally  accepted

in the United States of America requires management to make estimates and  assumptions. These
estimates and assumptions affect the reported amounts of assets and liabilities and  disclosure of
contingent assets and liabilities at the date of the financial statements and the reported amounts of
revenues and expenses during the reporting period. Actual results could  differ from those  estimates.

(c) Cash and Cash Equivalents

Cash and cash equivalents consist of short-term, highly liquid investments with remaining

maturities of three months or less when purchased.

(d) Derivative Instruments and Hedging

The Company records all derivatives, which consist of foreign currency exchange contracts, on the

balance sheet at fair value. Derivatives that are not accounting hedges must be adjusted  to  fair value
through earnings. If a derivative is a 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 included
in accumulated other comprehensive income depending on the nature of the hedge.  The ineffective
portion of a derivative’s change in fair value is immediately recognized in earnings. The Company does
not account for any derivatives using hedge accounting treatment during the periods  presented and
therefore the changes in the fair value of derivatives is recognized in earnings.

Forward foreign exchange contracts are  used  by the  Company to offset certain installment and
accounts receivable cash flow exposures resulting from changes in foreign currency exchange rates.
Such exposures have historically resulted from portions of the Company’s installments receivable that
are denominated in currencies other than the U.S. dollar, primarily the Euro, Japanese Yen, Canadian
Dollar and the British Pound Sterling.  The Company retained currency exposures  as part of the June
2005 and September 2006 transfers of installments receivable to its unconsolidated subsidiaries. The
Company has also retained foreign currency exposure for certain collateralized installment and accounts
receivables transferred under its traditional programs (See Note 4 ‘‘Secured Borrowings and
Collateralized Receivables’’).

ASPEN TECHNOLOGY, INC. AND  SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(2) Significant Accounting Policies (Continued)

At June 30, 2007, the Company had entered into currency forward contracts intended to mitigate a

portion of the cash flow exposure on $26.9 million of installments receivable and accounts receivable
denominated in foreign currency. The  gross value of the held and securitized  installments receivable
that were denominated in foreign currency was $46.0 million at June 30, 2006 and $53.7 million at
June 30, 2007. The installments receivable as of June 30, 2007 mature at various times through June
2012.

The Company records its foreign currency exchange contracts at fair value in its consolidated
balance sheet and the related gains or losses on these contracts are recognized  in earnings.  During
fiscal 2005, 2006 and 2007, the net loss recognized in the consolidated statements of operations was not
material.

The following table provides information about the Company’s foreign currency  derivative financial

instruments outstanding as of June 30, 2007. The table presents the notional amount (at contract
exchange rates) and the fair value of the derivatives in U.S. dollars:

The fair value is derived from the  estimated  amount  at  which the contracts could be
settled based on the forward rates as of June 30, 2007. Credit risk on derivatives arises if
the Company’s banking counterparties are unable to meet the  terms of the  agreements.
The Company minimizes such risk by limiting its counterparties to major financial
institutions. 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  the
market and credit risks described above.

(e) Depreciation and Amortization

The Company provides for depreciation and amortization, primarily computed using the

straight-line method, by charges to operations in amounts estimated to allocate the cost of the assets
over their estimated useful lives, as follows:

Classification

Estimated Useful Life

Computer equipment . . . . . . . . . . . . . .

Furniture and fixtures . . . . . . . . . . . . . .

(2) Significant Accounting Policies (Continued)

Depreciation expense was $10.1 million, $5.8 million and $5.0 million for the years ended June 30,

2005, 2006 and 2007, respectively.

(f) Revenue Recognition

The Company recognizes revenue in accordance with Statement of Position (SOP) No. 97-2,
‘‘Software Revenue Recognition,’’ as amended and interpreted. License  revenue, including license
renewals, consists principally of revenue 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  (VSOE)
of fair value exists for all undelivered elements, such as maintenance support, consulting and training
services. The Company determines VSOE based upon the price charged when the same element  is sold
separately. Consulting and training services VSOE represents rates that the Company charges its
customers when the Company sells these 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. The Company uses installment contracts as a standard business practice
and has a history of successfully collecting under the original  payment  terms  without making
concessions on payments, products or services.

Revenue under license arrangements,  which may  include  several different software products and
services sold together, are allocated to the delivered elements based on the residual method.  Under the
residual method, the fair value of the undelivered elements is deferred and subsequently recognized
when earned and the residual amount for the delivered elements is recognized in revenue when  all
other revenue recognition criteria are met. The Company has established VSOE for consulting services,
training and maintenance and support services. Accordingly, software license revenues are recognized
under the residual method in arrangements in which software is bundled with  consulting services,
training and maintenance and support services. Consulting services do not generally involve  customizing
or modifying the licensed software, but rather involve helping customers deploy the software  to  their
specific business processes. The Company generally accounts for the services element of the
arrangement separately. Occasionally, the Company provides consulting services considered essential to
the functionality of the software or provides services for the significant production, modification  or
customization of the licensed software and recognizes revenue for such services and any related
software licenses in accordance with SOP 81-1, ‘‘Accounting for  Performance of Construction Type and
Certain Performance Type Contracts’’ using the percentage-of-completion method.

When a loss is anticipated on a service contract, the full amount thereof is provided currently.

Service revenues and consulting and training revenue are recognized as the related services are
performed using the proportional performance method. 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 deferred revenue in the
accompanying consolidated balance sheets. Reimbursement received for out-of-pocket expenses  is
recorded as revenue.

The Company has a practice of licensing its products through resellers in certain regions. For
software licensed through these distribution channels, revenue is recognized at the time of delivery to

F-9

ASPEN TECHNOLOGY, INC. AND  SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(2) Significant Accounting Policies (Continued)

the end customer, when persuasive evidence of an arrangements exists, the fee is fixed or determinable,
collection is reasonably assured and other revenue recognition criteria are met.

Maintenance and support services 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 sold independently
at time of renewal. The Company generally does not provide specified upgrades to its customers  in
connection with the licensing of its software products.

(g) Computer Software Development Costs

Certain computer software development costs are capitalized in the accompanying consolidated

balance sheets. Capitalization of computer software development costs begins upon the  establishment
of technological feasibility. In accordance with Statement of Financial  Accounting Standard (SFAS)
No. 86, ‘‘Accounting for the Costs of Computer  Software to be Sold,  Leased, or otherwise Marketed,’’
the Company defines the establishment of technological feasibility as the  completion  of a detail
program design. Amortization of capitalized computer software development costs is provided  on a
product-by-product basis using (a) the greater of the amount computed  using the ratio that current
gross revenues for a product bear to total of current and anticipated future gross revenues  for that
product or (b) the straight-line method, beginning upon commercial release of the  product, and
continuing over the remaining estimated economic life of the product, not to exceed three years. At
each balance sheet date, the Company evaluates the unamortized capitalized software costs for
potential impairment by comparing to the net realizable value of the products. Total  amortization
expense charged to operations was approximately $8.0 million, $9.2 million and $7.9  million in fiscal
2005, 2006 and 2007, respectively.

(h) Foreign Currency Translation

The determination of the functional currency of subsidiaries is based on the subsidiaries’  financial

and operational environment and is normally the local currency. Gains and  losses from foreign  currency
translation related to entities whose functional currency is their local currency are  credited or  charged
to accumulated other comprehensive income (loss), included in stockholders’ equity (deficit) in the
consolidated balance sheets. In all instances, foreign currency transaction gains or  losses are credited or
charged to the consolidated statements of operations as incurred.

(i) Net Income (Loss) per Share

Basic earnings per share was determined by dividing income (loss) attributable to common
shareholders by the weighted average common shares outstanding during the period. Diluted earnings
per share was determined by dividing income (loss) attributable to common shareholders by diluted
weighted average shares outstanding. Diluted weighted average shares reflects the dilutive effect, if any,
of potential common shares. To the extent their effect is dilutive,  potential  common shares include
common stock options and warrants, based on the treasury stock method, convertible preferred stock,
based on the if-converted method, and other commitments to be settled in common stock. The
calculations of basic and diluted net income (loss) per share attributable to common shareholders and

(j) Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations  of credit  risk are

principally cash and cash equivalents, accounts receivable and installments and collateralized
receivables. The Company places its cash and cash equivalents and investments in financial institutions
management believes to be high credit quality. Concentration of credit risk with respect to receivables
is limited to certain customers (end users and distributors) to which the Company makes substantial
sales. To reduce risk, the Company assesses the financial strength  of its  customers and will often
transfer its installments receivable to financial institutions with limited or no credit recourse. The
Company does not generally require collateral or other security in support of its receivables. As of
June 30, 2006 and 2007, the Company had no customers that represented more than 10% of total
receivables.

(k) Allowance for Doubtful Accounts and Discounts

The Company makes judgments as to its ability to collect outstanding receivables and provides
allowances for the portion of receivables when a loss has been incurred. Provisions are made based
upon a specific review of all significant outstanding invoices and an analysis of loss  experience. In
determining these provisions, the Company analyzes its historical collection  experience  and current
economic trends. The allowance for doubtful accounts on installment and collateralized receivables
primarily represents the carrying value of the impaired loans.

(l) Financial Instruments

Financial instruments consist of cash and cash equivalents,  accounts receivable, installments
receivable, collateralized receivables, accounts payable, long-term obligations  and  foreign  exchange
contracts. The estimated fair value  of these financial instruments approximates the  carrying value. The
fair value of the collateralized receivables is less than the carrying value by $5.2 million.

The Company tests goodwill for impairment annually at the reporting unit level  using a fair value
approach in accordance with the provisions of SFAS No. 142, ‘‘Goodwill and other  Intangible Assets.’’
The Company conducted its annual impairment test on December 31, of each year. The  Company’s
next annual impairment test will occur on December 31, 2007. If an event occurs  or circumstances
change that would more likely than not reduce the fair value of a reporting unit below  its  carrying
value, goodwill will be evaluated for impairment between annual tests.

The Company evaluates it long-lived assets, which include property and leasehold  improvements,

intangible assets and capitalized software development costs for  impairment as events and
circumstances indicate that the carrying amount may not be recoverable. The Company evaluates the
realizability of its long-lived assets based on undiscounted cash flow expectations for the  related asset.

(n) Comprehensive Income (Loss)

Comprehensive income (loss) is defined as the change in equity of a business enterprise during a
period from transactions and other events and circumstances from non-owner sources. Comprehensive
income (loss) is disclosed in the accompanying consolidated statements of stockholders’ equity (deficit)
and comprehensive income (loss). The components of accumulated other comprehensive income  (loss)
as of June 30, 2006 and 2007 consist of cumulative translation adjustments.

(o) Accounting for Stock-Based Compensation

The Company adopted SFAS No. 123 (revised 2004), ‘‘Share-Based  Payment,’’ (SFAS No.123(R))

effective July 1, 2005. Under the provisions of this statement, stock-based compensation cost is
measured at the grant date based on the fair value of the award and is recognized as expense over the
vesting period. Prior to the adoption of SFAS No. 123(R),  the Company used  the intrinsic value
method. Under the intrinsic value method, stock-based compensation is recognized when the award is
less than the fair value on the measurement date. See Note 9, ‘‘Stock-Based Compensation,’’ in the
notes to consolidated financial statements for more discussion.

(p) Accounting for Transfers of Financial Assets

The Company derecognizes financial assets when control has been surrendered in compliance with

SFAS No. 140, ‘‘Accounting for Transfers  and Servicing of Financial Assets  and Extinguishments  of

F-14

ASPEN TECHNOLOGY, INC. AND  SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(2) Significant Accounting Policies (Continued)

Liabilities’’ (‘‘SFAS No. 140’’). Transfers of assets  that meet the requirements of SFAS  No. 140 for  sale
accounting treatment are removed from the balance sheet and gains or losses on the sale  are
recognized. If the conditions for sale accounting treatment are not met, or are no longer  met, assets
transferred are classified as collateralized receivables in the consolidated  balance sheet  and  cash
received from these transactions is classified as secured borrowings. All  transfers of assets  during the
years ended June 30, 2005, 2006 and 2007 are accounted for as secured borrowings. Transaction costs
associated with secured borrowings, if any, are treated as borrowing costs and  recognized  in  interest
expense. As customer payments are made on the collateralized receivables, the  collateralized receivable
and debt obligation are reduced.

(q) Income Taxes

Deferred income taxes are recognized based on temporary differences between the financial
statement and tax bases of assets and liabilities. Deferred tax assets and liabilities are measured  using
the statutory tax rates and laws expected to apply to taxable income in the years in which the
temporary differences are expected to reverse. Valuation allowances are provided against net  deferred
tax assets if, based upon the available evidence, it is more likely  than not that some or all of the
deferred tax assets will not be realized. The ultimate realization  of  deferred tax assets  is  dependent
upon the generation of future taxable income  and the timing of the temporary  differences becoming
deductible. Management considers, among other available information, scheduled reversals of deferred
tax liabilities, projected future taxable income, limitations of availability of net operating loss
carryforwards, and other matters in making this assessment.

Income taxes are provided on undistributed earnings of foreign subsidiaries where such earnings
are expected to be remitted to the U.S. parent company. The Company does not provide deferred taxes
on unremitted earnings of foreign subsidiaries that it intends to reinvest for the foreseeable future.
Unrecognized provisions for taxes on undistributed earnings of foreign subsidiaries, which are
considered permanently invested, are not material to the Company’s consolidated financial position or
results of operations.

The Company is continuously subject to examination by the IRS, as well as various  state and
foreign jurisdictions. The IRS and other taxing authorities may challenge certain deductions and credits
reported by the Company on its income tax returns. In accordance with SFAS No. 5,  ‘‘Accounting for
Contingencies,’’ the Company establishes reserves for tax contingencies  that reflect its  best estimate of
the deductions or tax credits that it may be unable to sustain, or that are probable to be conceded as
part of a broader tax settlement. The Company accrues interest and penalties on underpayment of tax
obligations and these costs are classified in the income tax provision. Differences between the reserves
for tax contingencies and the amounts ultimately owed by the Company are recorded in the period they
become known. Future adjustments to the Company’s  reserves could have a material effect  on the
Company’s financial statements.

(r) Legal Fees and Contingencies

The Company accrues estimated future legal fees associated with outstanding litigation for which

management has determined that it is probable that a loss contingency exists. Liabilities for loss
contingencies arising from claims, assessments, litigation and other sources are recorded when it is

F-15

ASPEN TECHNOLOGY, INC. AND  SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(2) Significant Accounting Policies (Continued)

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

(s) Advertising Costs

The Company charges advertising costs to expense as the costs are  incurred. The Company

incurred advertising expenses of $7.3 million, $2.0 million and $1.8  million during the years ended
June 30, 2005, 2006 and 2007, respectively. As of June 30, 2006 and 2007, the  Company had no prepaid
advertising costs included in the accompanying consolidated balance sheets.

(t) Accounting for Restructuring Accruals

The Company follows SFAS No. 146, ‘‘Accounting for Costs Associated with Exit or Disposal
Activities’’ for all restructuring activities  initiated after December 21, 2002. In accounting  for these
obligations, the Company is required to make assumptions related to the amounts  of  employee
severance, benefits, and related costs and to the time period over which facilities will remain vacant,
sublease terms, sublease rates and discount rates. Estimates and assumptions  are based on the best
information available at the time the obligation has arisen. These estimates are reviewed and revised as
facts and circumstances dictate; changes in these estimates could  have a material  effect on the  amount
accrued on the balance sheet.

(u) Acquisition

In May 2007, the Company acquired certain assets and assumed certain liabilities of Plant
Solutions Pty Ltd (Plant Solutions). Plant Solutions was a sales-agent of the Company that  marketed
products primarily in Australia and New Zealand. The Company acquired  this business to expand its
direct selling efforts in this region. The $1.3 million purchase price consisted of a $1.2 million cash
payment and $0.1 million in transaction costs. In addition, there is $0.2 million in contingent payments
that will be paid upon resolution of certain closing items, and if paid will result in  an increase in the
purchase price.

Allocation of the purchase price was based on a preliminary estimate of the fair value of the net

assets acquired and is subject to change as the Company finalizes its purchase accounting. The
purchase price was allocated to the fair market value of assets acquired and liabilities assumed, as
follows (in thousands):

(v) Recently Issued Accounting Pronouncements

In July 2006, the Financial Accounting Standards Board (FASB) issued Interpretation  No. 48,

‘‘Accounting for Uncertain Tax Positions,  an Interpretation of FASB Statement  No. 109,’’ or FIN 48,
which clarifies the criteria for recognition and measurement of benefits from uncertain tax positions.
Under FIN 48, an entity should recognize a tax benefit when it is ‘‘more-likely-than-not,’’ based  on the
technical merits, that the position would be sustained upon examination by  a  taxing  authority.  The
amount to be recognized, if the ‘‘more-likely-than-not’’ threshold was passed, should be measured as
the largest amount of tax benefit that is greater than 50 percent likely of being realized upon ultimate
settlement with a taxing authority that has full knowledge of all relevant information. Furthermore, any
change in the recognition, derecognition or measurement of a tax position should be recognized in the
period in which the change occurs.

The Company adopted FIN 48 as of July 1, 2007, and any change in net assets as a result of
applying FIN 48 is recognized as an adjustment to accumulated deficit  on that date. As  a result  of  the
implementation of FIN 48 on July 1, 2007, the Company recognized an increase of approximately
$3.0 million in the liability for unrecognized tax benefits, which was accounted for  as an increase to the
accumulated deficit. In addition, as of July 1, 2007, the Company had $7.4 million of deferred tax  assets
that were de-recognized upon adoption standard of FIN 48. These amounts did not result in  an
adjustment to the accumulated deficit at July 1, 2007 as a result of the full valuation allowance
recorded against these deferred tax assets.

The Company has historically accounted for interest and penalties related to uncertain tax
positions as part of its provision for income taxes. Upon adoption of FIN 48, the Company will
continue this classification. As of June 30, 2007, the  Company  has accrued $6.9 million of interest and
penalties related to uncertain tax positions. Prior to July 1, 2007, the  Company classified income  taxes
payable as a current liability. Under FIN 48, the Company is required to classify those  obligations that
are expected to be paid within the next twelve months as a current obligation and the remainder as a
non-current obligation. As of July 1, 2007, the Company classified $10.6 million as non-current
obligations.

In September 2006, the FASB issued SFAS No. 157, ‘‘Fair Value Measurements’’ (SFAS No. 157).

SFAS No. 157 establishes a framework for measuring fair  value  in generally accepted accounting
principles and expands disclosures about fair  value measurements. SFAS No. 157, emphasizes  that fair
value measurement is market-based, not entity-specific, and establishes  a fair value hierarchy in which
the highest priority is quoted prices in active markets. Under SFAS No. 157, fair value measurements
are disclosed according to their level within this hierarchy. SFAS No. 157 is effective for fiscal years
beginning after November 15, 2007 except for nonrecurring fair value measurements of nonfinancial
assets and nonfinancial liabilities, for which the effective date is fiscal years beginning after
November 15, 2008. The Company has not yet determined the effect that the application of SFAS
No. 157 will have on its consolidated financial statements.

In February 2007 the  FASB issued SFAS No. 159, ‘‘The Fair  Value Option for Financial  Assets and

Financial Liabilities’’ (SFAS No. 159). SFAS No. 159 permits  entities to measure many financial
instruments and certain other items at fair value and provides entities with the opportunity to mitigate
volatility in reported earnings caused by measuring related assets and liabilities differently without
having to apply complex hedge accounting provisions. Once an entity has elected the fair value option
for designated financial instruments and other items, changes in fair value must be recognized in the

F-17

ASPEN TECHNOLOGY, INC. AND  SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(2) Significant Accounting Policies (Continued)

statement of operations. SFAS No. 159 is effective for fiscal years  beginning after November 15, 2007.
The Company has not yet determined the effect that the application of  SFAS No. 159 will have on its
consolidated financial statements.

In December 2007, the FASB issued SFAS No. 141(R), ‘‘Business Combinations,’’  which replaces
SFAS No. 141. SFAS No. 141R establishes principles and requirements for how an acquirer recognizes
and measures in its financial statements the identifiable assets acquired, the liabilities assumed,  any
noncontrolling interest in the acquiree and the goodwill acquired. The Statement also establishes
disclosure requirements which will enable users to evaluate the nature and financial effects of the
business combination. SFAS No. 141R is effective for fiscal years beginning after December 15,  2008.
The Company expects SFAS No. 141R will have an impact on accounting for business combinations
once adopted but the effect is primarily dependent upon future acquisitions.

In December 2007, the FASB issued SFAS No. 160, ‘‘Noncontrolling Interests in Consolidated
Financial Statements—an amendment of Accounting Research Bulletin No. 51’’ (‘‘SFAS No. 160’’),
which establishes accounting and reporting standards for ownership  interests in subsidiaries held by
parties other than the parent, the amount of consolidated net income attributable to the parent  and to
the noncontrolling interest, changes in a parent’s ownership interest and the valuation of retained
noncontrolling equity investments when a subsidiary is deconsolidated. The Statement  also establishes
reporting requirements that provide sufficient disclosures that clearly identify and distinguish between
the interests of the parent and the interests of the noncontrolling owners. SFAS No.  160 is  effective for
fiscal years beginning after December 15, 2008. The Company has not determined  the effect that  the
application of SFAS No. 160 will have on its consolidated financial statements, although no minority
interests are reported as of June 30, 2007.

In March 2008, the FASB issued SFAS No. 161, ‘‘Disclosures about Derivative Instruments and
Hedging Activities, an amendment of FASB Statement No. 133.’’ This statement changes the disclosure
requirements for derivative instruments and hedging activities. SFAS No. 161 requires enhanced
disclosures about (a) how and why an entity uses derivative instruments, (b) how derivative instruments
and related hedged items are accounted for under SFAS No. 133 and its related interpretations, and
(c) how derivative instruments and related hedged items affect an  entity’s financial position, financial
performance, and cash flows. This statement is effective for financial statements issued for fiscal years
and interim periods beginning after November 15, 2008. The Company has not yet determined the
effect that the application of SFAS No. 161 will have on its consolidated financial statements.

(3) Restructuring Charges and FTC Legal  Costs (Continued)

During fiscal 2007, the Company recorded $4.6 million in restructuring charges. Of this amount,

$3.6 million related to headcount reductions and $1.0 million related to facility closures under the
Company’s May 2005 restructuring plan.

At June 30, 2007, total restructuring liabilities included  $0.8 million for employee severance,
benefits, and related costs and $13.4 million for the closure of facilities. Management anticipates that
payments of $4.0 million will be made over the next twelve months and the remaining $10.2 million will
be made through 2012.

(a) Restructuring charges originally arising  in  the three months ended  June 30, 2007

In May 2007, the Company initiated a plan to relocate its corporate headquarters from Cambridge
to Burlington, Massachusetts. The relocation resulted in the Company ceasing to use  its  prior corporate
headquarters leased space, subleasing the space to a third party,  and  the relocation to a new facility.
During the year ended June 30, 2007, the Company recorded a charge of $0.1 million associated with
the relocation of certain departments to temporary space. The closure and relocation actions were
completed in October 2007 and resulted in a total restructuring charge of $6.0 million in the quarter
ended September 30, 2007.

(b) Restructuring charges originally arising  in  the three  months ended  June 30, 2005

In May 2005, the Company initiated a plan to consolidate several corporate functions and to
reduce its operating expenses. The plan to reduce operating expenses primarily resulted in headcount
reductions, and also included the termination of a contract and the consolidation of facilities. These
actions resulted in an aggregate restructuring charge of $3.8 million, recorded in the  fourth quarter of
fiscal 2005. During the years ended June 30, 2006 and 2007,  the Company recorded an additional
$1.8 million and $4.6 million, respectively, related to headcount reductions, relocation costs  and facility
consolidations associated with the May 2005 plan that did not qualify for accrual at June 30, 2005.

Under this restructuring plan, the Company has yet to incur charges related to the closure of

certain offices and relocation of certain employees. The Company expects  that these charges will be
approximately $2.3 million and will primarily be completed by June 2008.

Closure/consolidation of facilities: Approximately $0.1 million, $0.6 million and $1.0 million of the
restructuring charges recorded in fiscal 2005, 2006 and 2007, respectively, related  to  the termination of
facility leases.

Employee severance, benefits and related costs: Approximately $3.5 million, $1.2 million and

$3.6 million of the restructuring charges recorded in fiscal 2005, 2006, and 2007, respectively, related to
the reduction in headcount. Approximately 130 employees, or 10% of the workforce, were eliminated
under the restructuring plan. The employees were primarily located in North America  and Europe. All
business units were affected, including services, sales and marketing, research and  development, and
general and administrative.

Contract termination costs: Approximately $0.3 million of the restructuring charge in fiscal 2005

related to charges associated with the termination of a contract  for  a future user  conference.  The
contract was terminated in June 2005.

(c) Restructuring charges originally arising in the three months ended  June 30, 2004

In June 2004, the Company initiated a plan to reduce its operating expenses in order to better
align its operating cost structure with the current economic environment and to improve operating
margins. The plan to reduce operating expenses resulted in the consolidation of facilities, headcount
reductions, and the termination of operating contracts. These actions resulted in an aggregate
restructuring charge of $23.5 million, recorded in the fourth quarter of fiscal 2004. During the year
ended June 30, 2005, the Company recorded $14.4 million related to headcount reductions and facility
consolidations associated with the June 2004 restructuring plan that did not qualify for accrual at
June 30, 2004. In addition, the Company recorded $0.4 million in restructuring charges related to the
accretion of the discounted restructuring accrual and a $0.8 million decrease to the accrual related to
changes in estimates of severance benefits and sublease terms. During the years ended June 30, 2006
and 2007, the Company recorded a $0.7 million increase and a $0.2 million decrease, respectively, to

the accrual primarily due to changes in the estimate of future  operating  costs and sublease assumptions
associated with the facilities.

As of June 30, 2007, there was $5.1 million remaining in accrued expenses relating to the

remaining severance obligations and lease payments. The  following  activity was recorded  for the

September 2012

March  2008

Closure/consolidation of facilities: Approximately $9.1 million of the fiscal 2005 restructuring
related to the termination of facility leases and other lease related costs. The costs recorded in fiscal
2005 related to termination activities did not qualify for accrual as of June 30, 2004. 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 $4.4 million of the fiscal 2005
restructuring charge, related to the reduction in headcount. In the aggregate, approximately 147
employees, or 9% of the workforce, were eliminated under the restructuring plan implemented by
management. The fiscal 2005 restructuring charge related to employees had not been notified in a
manner that would allow for accrual as of June 30, 2004. Such notification occurred in Q1, 2005. A
majority of the employees were located in North America, although Europe was affected as well. All
business units were affected, including services, sales and marketing, research and development, and
general and administrative.

(3) Restructuring Charges and FTC Legal  Costs (Continued)

Impairment of assets: Approximately $1.0 million of the fiscal 2005 restructuring charge related to

charges associated with the impairment of fixed assets associated with the closed and consolidated
facilities. These assets were considered to be impaired because their carrying values were  in excess of
their fair values.

(d) Restructuring charges originally arising in the three  months ended  December 31, 2002

In October 2002, management initiated a plan to further reduce operating expenses  in response to

first quarter revenue results that were below expectations and to general economic uncertainties.  The
plan to reduce operating expenses resulted in headcount reductions, consolidation of facilities, and
discontinuation of development and support for certain non-critical products. These actions resulted  in
an aggregate restructuring charge of $28.7 million. During fiscal 2005, 2006 and 2007, the Company
recorded a $7.0 million and $1.0 million increase and a $0.2 million decrease, respectively,  to the
accrual primarily due to a change in the estimate of the facility vacancy term, extending  to  the term of
the lease.

As of June 30, 2007, there was $8.0 million remaining in accrued expenses relating to the

remaining lease payments. The following activity was recorded for the indicated years (in  thousands):

(e) Restructuring charges originally arising  in  the three months ended June 30, 2002

In the fourth quarter of fiscal 2002, management initiated a plan to reduce operating expenses and

to restructure operations around the Company’s two primary product lines, engineering software and

manufacturing/supply chain software. The Company reduced worldwide headcount by approximately
10%, or 200 employees, closed and consolidated facilities,  and  disposed of certain  assets, resulting in an
aggregate restructuring charge of $13.2 million. During fiscal 2005, the Company recorded a
$0.2 million increase to the accrual due to changes in estimates of sublease assumptions  and severance
settlements. During fiscal 2006 and 2007, the Company recorded less than $0.1 million in  increases to
the accrual due to changes in sublease assumptions.

As of June 30, 2007, there was $0.4 million remaining in accrued expenses relating to lease

payments. The following activity was recorded for the indicated years (in thousands):

Closure/consolidation of facilities: The amount accrued is an estimate of the actual costs to

buy-out leases or to sublease the underlying properties. The revisions to the accrual in fiscal 2005, 2006,
and 2007 relate to revised estimates with respect to the facility vacancy terms.

(4) Secured Borrowings and Collateralized Receivables

The Company has transferred customer installment and  trade receivables  to  financial institutions
or unconsolidated special purpose entities (referred to herein as ‘‘receivable sale facilities’’) that have
been accounted for as secured borrowings. The transferred receivables serve as collateral  under the
receivable sales facilities.

At June 30, 2006 and 2007, receivables  totaling  $211.3 million and $245.1  million, respectively,

were pledged as collateral for the secured borrowings. The secured borrowings totaled $182.4 million
and $206.2 million as of June 30, 2006 and 2007, respectively. The collateralized installment receivables
are presented net of applicable discounts for interest established for the individual receivable. The
interest rates implicit in the installment receivables for the years ended June 30, 2005, 2006, and 2007
ranged from 5.0% to 9.0%. The Company recorded $12.8 million, $14.9 million and $11.6 million of
interest income associated with the collateralized receivables for the years ended June 30, 2005, 2006,
and 2007, respectively, and recognized $12.6 million, $18.5 million, and $17.5 million of interest expense
associated with the secured borrowings. Proceeds from and payments on the secured  borrowings are
presented as components of cash flows from financing activities in the consolidated statements of cash

F-23

ASPEN TECHNOLOGY, INC. AND  SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(4) Secured Borrowings and Collateralized Receivables (Continued)

flows. Payments on secured borrowings and operating cash flows  from collateralized receivables are
recognized upon customer payment of amounts due.

Traditional Programs

The Company has arrangements to transfer certain of its receivables  to  three financial institutions

at the mutual agreement of the Company and the financial institution for each such customer
receivable. The transfers of customer receivables under these programs have been accounted for  as
secured borrowings. The Company received cash proceeds of $115.7 million, $110.5 million and
$148.8 million for the years ended June 30, 2005, 2006 and 2007, respectively, related to these
programs.

The total collateralized receivables for the Traditional Programs approximate the amount of the

secured borrowings recorded in the consolidated balance sheet. The collateralized receivables earn
interest income and the secured borrowings accrue borrowing costs at approximately the same  interest
rates. The secured borrowings and collateralized receivables  are reduced as the  related  customer
receivable is collected. The terms of the customer accounts receivable range from amounts  that are due
within 30 days to installment receivables that are due over five years. The Company acts as the servicer
for the receivables in one of the three arrangements.

Under the terms of the Traditional Programs the Company has transferred the receivables  to  the

financial institutions with limited financial recourse. Potential recourse obligations are primarily related
to one program that requires the Company to pay interest to the financial institution  when the
underlying customer has not paid by the installment due date. This recourse is limited to a  maximum
period of 90 days after the due date. The amount of outstanding installment receivables  that  has this
potential recourse obligation is $51.5 million at June 30, 2007. This recourse  obligation is recognized as
interest expense as incurred and totaled $0.5 million, $0.4 million, and $0.7 million for  the years ended
June 30, 2005, 2006, and 2007, respectively. In addition, the Company has  recourse  obligations totaling
$1.5 million at June 30, 2007 if the underlying installment receivable is not paid by the customer. This
recourse obligation is in the form of a deferred payment by the financial institution that is withheld
until customer payments are received.

Securitization of Accounts Receivable

The Fiscal 2005 and Fiscal 2007 securitization transactions (described  below) include collateralized

receivables whose value exceeds the related borrowings from the financial institutions. The Company
receives and retains collections on these securitized receivables after all borrowing and related costs are
paid to the financial institution. The financial institutions’ rights to repayment are limited to the
payments received from the collateralized receivables. The carrying value of the collateralized
receivables at June 30, 2007 under these arrangements was $61.9 million and the secured borrowings
totaled $25.8 million. The collateralized receivables earn interest income and the secured borrowings
result in interest expense. The secured borrowings incur a higher interest rate than the implicit rates in
the receivables. The Company acts as the servicer under both of these arrangements and the customer
collections are used to repay the secured borrowings, interest and related costs.

(4) Secured Borrowings and Collateralized Receivables (Continued)

Fiscal 2005 Securitization

On June 15, 2005, the Company securitized and transferred installment receivables with a net
carrying value of $71.9 million and received cash proceeds of $43.8 million. This transfer  did not meet
the criteria for a sale and has been accounted for as a secured borrowing. These borrowings  are
secured by collateralized receivables and the debt and borrowing costs are repaid  as  the receivables are
collected. The Company capitalized $2.1 million of debt  issuance costs associated with this transaction
and these costs are being recognized in interest expense using the  effective interest method.
Accumulated amortization of the debt issue costs were $1.2  million  and $1.9 million  at June 30,  2006
and 2007, respectively. Amortization expense of the debt issuance costs  was  $1.1 million and
$0.7 million for the years ended June 30, 2006 and 2007, respectively.

Fiscal 2007 Securitization

On September 29, 2006, the Company entered into a three year revolving securitization facility and

securitized and transferred installment receivables with a net carrying  value of $32.1 million and
received cash proceeds of $20.0 million. This transfer did not meet the criteria  for a sale and has been
accounted for as a secured borrowing. These borrowings are secured by collateralized receivables and
the debt and borrowing costs are repaid as the receivables are collected. The Company  capitalized
$1.1 million of debt issuance costs associated with this transaction and these costs  are being recognized
in interest expense using the effective interest method. Accumulated amortization of the debt issue
costs and amortization expense of debt issue costs were $0.4 million as of and for the year ended
June 30, 2007.

The Fiscal 2007 Securitization facility provides that the Company  can borrow up  to  $75.0 million

under the facility. The availability under the facility is limited to the amount of eligible receivables  and
subject to the discretion of the financial institution. As of June 30, 2007, the Company has
approximately $58.2 million of maximum availability under this facility.

The secured borrowings consist of the following at June 30, 2006 and  2007 (in thousands):

borrowings. The Company has no future cash obligations other than the limited recourse  obligations
noted above.

In December 2007, the Company paid the outstanding amount of the fiscal 2005 securitization at

its carrying value. The unamortized debt issue costs were charged to expense  at the  time.

The Company had been in violation of certain covenants related to the Fiscal 2007 Securitization

due to the delay in filing its financial statements and other violations.  The  secured borrowings under
this arrangement have been classified in the current portion of secured borrowings. In March 2008, the
Company paid the outstanding amount of the Fiscal 2007 Securitization at  its carrying value  plus a
termination fee of $0.8 million, and this securitization is no longer available. The unamortized  debt
issue costs were charged to expense at the time.

(6) Line of Credit

In January 2003 and through subsequent amendments, 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 (8.25% at June 30, 2007). The Company needs  to maintain a $4.0 million
compensating cash balance with the bank, or it is subject to an unused line fee and collateral handling
fees. The lines of credit are  collateralized by nearly all of the assets of the  Company, and  upon the
Company’s achieving certain net income targets, the collateral would be reduced to a  lien on the
accounts installments receivable that are not already pledged as collateral against the secured
borrowing. The Company is required to meet certain financial covenants, including minimum tangible
net worth, minimum cash balances and an adjusted quick ratio. The terms of the Loan Arrangement
restrict the Company’s ability to pay dividends, with the exception of dividends paid in common stock
or preferred stock dividends in cash. The Company was not in compliance with certain requirements
under the terms of the Loan Arrangement as  of June 30, 2007 and has  obtained waivers  for such
non-compliance.

As of June 30, 2007, there were $7.4 million in letters of credit outstanding under the line of
credit, and there was $13.1 million available for future borrowing. On October 16, 2007, the Company
executed an amendment to the Loan Arrangement that adjusted the  terms of certain financial

covenants, including modifying the date the Company must provide  monthly unaudited and  annual

Series D redeemable convertible preferred stock

In August 2003, the Company issued and sold 300,300 shares of Series D-1 redeemable convertible

preferred stock (Series D-1 Preferred), along with warrants to purchase up to 6,006,006 shares of
common stock at a price of $3.33 per share, in a private placement to several investment partnerships
managed by Advent International Corporation for an  aggregate purchase  price of $100.0  million.
Concurrently, the Company paid cash of $30.0 million and issued 63,064 shares of Series D-2
convertible preferred stock (Series D-2 Preferred), along with warrants to purchase up to 1,261,280
shares of common stock at a price of $3.33 per share, to repurchase all of the outstanding Series B
Preferred. In addition, the Company exchanged existing warrants to purchase 791,044 shares of
common stock at an exercise price ranging from $20.64 to $23.99 held by the  holders of the Series B
Preferred, for new warrants to purchase 791,044 shares of common stock at an exercise price of $4.08.
These transactions are referred to collectively as the Series D Preferred financing.

The Company incurred $10.7 million in costs related to the issuance of the Series  D-1 and D-2

Preferred (together, the Series D Preferred) and allocated the net proceeds received between the
Series D Preferred and the warrants on the basis of the relative  fair values at the  date of issuance,
allocating $15.5 million of proceeds to the warrants. The warrants are exercisable at  any time prior  to
the seventh anniversary of their issue date. The remaining discount on the Series  D Preferred was
accreted to its redemption value over the earliest period of redemption.

Each share of Series D Preferred was  entitled to vote on all matters in which holders of  common

stock were entitled to vote, receiving a number of votes equal to the number of shares of common
stock into which it was then convertible. In addition, holders of Series D-1 Preferred, as a separate
class, were entitled to elect a certain number of directors, based on a formula as defined in the
Series D Preferred Certificate of Designations. The holders of the  Series D-1 Preferred were  entitled to
elect a number of the Company’s directors calculated as a ratio of the Series D-1 Preferred voting
power as compared to the total voting power of the Company’s common stock. The Series D-1
Preferred holders were elected as three of the Company’s current directors.

The Series D Preferred earned cumulative dividends  at an  annual rate of 8%, which were payable

when and if declared by the Board of Directors, in cash or, subject to certain conditions, common
stock. As of June 30, 2006, the Company had accrued $28.5 million in dividends on the Series D
Preferred.

Each share of Series D Preferred was  convertible at any time into a number of shares of common

stock equal to its stated value divided by the then-effective conversion price. Each share of Series D
Preferred was convertible into 100 shares of common stock.

The Series D Preferred included redemption rights  at the option of the holders as follows: 50% on
or after August  14, 2009 and 50% on or after  August 14,  2010. The shares were redeemable  for cash at
a price of $333.00 per share, plus accumulated but unpaid dividends.

The Series D Preferred was subject to redemption  at the  option of the Company, at  any time after
August 2006 at a price of $416.25 per  share plus  any  accumulated and unpaid dividends if, among other
things, the average trading price of the Company’s common stock exceeds $7.60 per share for 45
consecutive days. If the Company makes such an election, the holders of the Series D Preferred may
elect to convert their Series D Preferred shares into shares of common stock  rather than have them
redeemed.

(8) Preferred Stock (Continued)

On May 16, 2006, the Holders of the Series D Preferred converted 30,000 shares  into  3,000,000
shares of common stock. At the time of the conversion the Company  also paid $2.4 million  in dividends
on the converted shares. In December 2006, the holders of the Series D-1 Preferred converted their
remaining 270,300 shares into 27,030,000 shares of common stock. In December 2006, the Company
announced that it would redeem any shares of its Series D-2 Preferred that were not converted by their
holders into common shares by January 30, 2007. In January 2007, the remaining 63,064 shares of
Series D-2 Preferred were converted by their  holder into 6,306,400  shares of common  stock. The terms
of the Series D-1 and D-2 Preferred required settlement of  all accrued  and  unpaid dividends  upon
conversion of these shares into common stock and dividend accrual would cease  upon such  conversion.
Accordingly, the Company paid $27.4  million in cash  in  December  2006 to the holders of the
Series D-1 Preferred, and paid $6.6 million in cash in January 2007 to the holders of the  Series D-2
Preferred for dividends accumulated  at  the date of conversion of the  respective tranches of securities.

As a result of the conversion of the Series D-1 and Series D-2 Preferred and the  related dividend
payments, the stated value of the Series D-1 Preferred was reduced from $125.5 million as of June  30,
2006 to $0 as of June 30, 2007, common stock outstanding was increased by $3.3 million and additional
paid-in-capital was increased by $95.5 million for the portion of the preferred stock  converted into
common shares.

In the accompanying consolidated statements of operations, the accretion of preferred stock

discount and dividend consist of the following (in thousands):

Registration Rights

In May 2006, the Company received a demand letter from the Series D-1 Preferred holders, in
accordance with the terms of their investor rights agreement with the Company, requesting registration
of all of the shares of common stock issued or issuable upon the conversion of Series D-1 Preferred
and the exercise of their warrants in connection with an underwritten public offering per the terms
defined in the investor rights agreement. The Company is required to register the  underlying shares at
its expense. As of June 30, 2007, the total number of outstanding shares of common stock that would
be included by their registration demand letter is 30,027,336.

(9) Stock-Based Compensation

Stock Compensation Plans

In May 2005, the shareholders approved the establishment of the 2005 Stock Incentive Plan (the
2005 Plan), which provides for the reservation of up to 4,000,000 shares of common stock for issuance
under the 2005 Plan. The 2005 Plan provides for the grant of incentive and nonqualified stock options
and other stock-based awards, including the grant of shares based upon certain conditions, the grant of
securities convertible into common stock and the grant of stock appreciation rights. Restricted stock

(9) Stock-Based Compensation (Continued)

and other stock-based awards granted under the 2005 Plan may not exceed, in the aggregate, 2,000,000
shares of common stock. As of June 30, 2007, there were 3,079,200 shares of common stock available
for issuance subject to awards under the 2005 Plan.

In December 2000, the shareholders approved the establishment of the 2001 Stock Option  Plan
(the 2001 Plan), which provides for the issuance of incentive stock options and nonqualified options.
Under the 2001 Plan, the Board of Directors could grant stock options to purchase up to an aggregate
of 4,000,000 shares of common stock. At July 1, 2002, July 1, 2003 and July 1, 2004, the 2001 Plan was
expanded to cover an additional 5% of the outstanding shares on the preceding  June 30. In no event,
however, may the number of shares subject to incentive options under the 2001 Option Plan exceed
8,000,000 unless the 2001 Plan is amended and such amendment is approved by the shareholders. As of
June 30, 2007, there were 112,439 shares of common stock available for grant under the 2001  Plan.

In December 1996, the shareholders of the Company approved the establishment  of  the 1996
Special Stock Option Plan (the 1996 Plan). This plan provides for the issuance of incentive  stock
options and nonqualified options to purchase up to 500,000 shares of common stock.  Stock options
become exercisable over varying periods and expire no later than 10 years from the date  of  grant. As of
June 30, 2007, there were no shares available for grant under the 1996 Plan.

In October 1997, the Company’s Board of Directors approved the 1998 Employee Stock Purchase
Plan, under which the Board of Directors may grant stock purchase rights for a maximum of 1,000,000
shares through September 30, 2007. In December 2000 and 2003, the shareholders voted  to  increase
the number of shares eligible under the 1998 Employee Stock Purchase Plan by  2,000,000 and 3,000,000
shares, respectively.

Employees are granted options to purchase shares of common stock on the last business day of
each semi-annual payment period for 85% of the market price of the common  stock on the first or last
business day of such payment period, whichever was less.  The purchase price for such  shares  was paid
through payroll deductions, and the June 30, 2007, maximum allowable payroll deduction was 10% of
each eligible employee’s compensation. Under the plan, the Company  issued 315,751  shares in 2005,
188,119 shares in 2006, and 107,862 shares in 2007. As of June 30, 2007, there  were 2,538,077  shares
available for future issuance under the 1998 Employee Stock Purchase Plan as amended. On July 1,
2007, the Company issued 51,311 shares under the 1998 Employee Stock Purchase Plan.

General Award Terms

The Company issues stock options to its employees and outside  directors, restricted  stock units to

its employees and provides employees the right to purchase stock pursuant to stockholder approved
stock option and employee stock purchase programs. Option awards are generally granted with an
exercise price equal to the market price of the Company’s stock at the date of grant; those options
generally vest over four years and have 7 or 10-year contractual terms. Restricted stock units vest over
four years (if performance conditions are met). The subscription period for the employee stock
purchase plan is six months.

Stock Compensation Accounting

The Company recognizes compensation costs on a straight-line basis over the requisite service

period for time vested awards. For awards that vest based on performance conditions, the Company

F-30

ASPEN TECHNOLOGY, INC. AND  SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(9) Stock-Based Compensation (Continued)

uses the accelerated model for graded vesting  awards. All of the Company’s stock-based compensation
is accounted for as equity instruments and there have been no liability awards granted. The Company’s
policy is to issue new shares upon exercise of stock awards. The Company adopted the simplified
method related to accounting for the tax effects of share-based payment awards to employees in FASB
Staff Position No. 123(R)-3, ‘‘Transition Election Related  to  Accounting for the Tax  Effects of Share-
Based Payment Awards.’’ The Company uses the ‘‘with-and-without’’ approach for  determining if excess
tax benefits are realized under SFAS No. 123(R).

Prior to the adoption of SFAS No. 123(R) on July  1, 2005, the  Company used the intrinsic value

method to account for employee stock awards. Under the intrinsic value method, compensation cost is
measured as the difference between the exercise price of the award and the grant date intrinsic value.
The Company has elected the modified prospective transition  method  for adopting SFAS  No. 123(R),
and consequently prior periods have not been modified. Under this method,  the provisions of  SFAS
No. 123(R) apply to all awards granted or modified after the date of adoption (July 1, 2005). The
unrecognized expense of awards not yet vested at the date of adoption is recognized in net income in
the periods after the date of adoption using the same valuation method (i.e. Black-Scholes) and
assumptions determined under the original provisions of SFAS No. 123, ‘‘Accounting for Stock-Based
Compensation’’ (SFAS No. 123). Stock-based compensation  for the years ended June 30, 2006  and 2007
are included in the following categories (in thousands):

The dividend yield of zero is based on the fact that the Company has never paid cash dividends on

common stock and has no present intention to pay cash dividends. Expected volatility is based on the
historical volatility of the Company’s common stock over the period commensurate with the  expected
life of the options. The risk-free interest rate is the U.S. Treasury zero coupon  bonds with a  maturity
commensurate with the expected life of the options on the date of grant. The expected  life was
calculated using the method outlined in SEC Staff Accounting Bulletin Topic 14.D.2,  ‘‘Expected Term’’
for fiscal 2006. In fiscal 2007, the Company calculated the estimated life based upon historical exercise
behavior.

In November 2006, the Company issued a total of 723,400 restricted stock units under  the 2005
Stock Incentive Plan to certain officers and management. The restricted stock units are performance
awards that vest 25% if the Company meets certain financial goals, which the Company concluded were
achieved in the first quarter of fiscal 2008. Upon the achievement of the initial  vesting milestone, the
remaining restricted stock units vest on a straight-line basis over the following three years. The
Company uses an accelerated model to recognize stock-based compensation expense  for these restricted
stock units as the awards have performance conditions and graded vesting provisions.

(9) Stock-Based Compensation (Continued)

At June 30, 2007, the total compensation  cost related  to  unvested awards not yet  recognized was

$14.5 million. The weighted average period over which this will be recognized is approximately
1.2 years. The total intrinsic value of options exercised during the years ended June  30,  2005, 2006 and
2007 was $3.9 million, $14.9 million and $10.4 million, respectively. The Company  received  $3.6 million,
$11.0 million and $8.5 million from option exercises during the years ended June 30, 2005,  2006 and
2007, respectively.

At June 30, 2007, common stock reserved  for  future issuance or settlement  under equity

compensation plans was 14,704,481 shares.

In December 2006 and May 2007, the Company modified awards for an aggregate of 1,184,470

options for employees of the company to equal the fair market value on the grant date of the
Company’s common stock for these awards to avoid certain adverse tax impacts on  the individuals.
There was no incremental compensation cost resulting from the modifications.  A further  modification
was made in December 2007 to increase the exercise price of certain awards and to provide for cash
payments to employees to compensate them for the increase in the  exercise  price of those  awards.

As a result of the Company not having a current effective registration statement on file with the
SEC, certain current and former employees were not able to exercise their options within the periods
included in the original option grant, and such options would have expired unexercised under their
original terms. The Company has modified such options to allow for their  exercise within a period
following the appropriate registration statements becoming effective with the SEC.

Prior to July 1, 2005, the Company’s employee  stock compensation plans  were accounted for in

accordance with Accounting Principles Board Opinion  No. 25, ‘‘Accounting for  Stock  Issued to
Employees’’ (APB No. 25) and related interpretations. The following table illustrates the effect on net
loss and loss per share if the Company had applied the fair value  recognition  provisions of SFAS

(10) Common Stock

(a) Warrants

The Company has issued warrants in connection with various financing activities. These  warrants

provide for net equity settlement and are accounted for in equity.

In connection with the February and March 2002 sales of Series B Preferred, the  Company  issued

warrants with five-year lives to purchase 791,044 shares of common stock  at an  exercise price ranging
from $20.64 to $23.99 per share. In August 2003, in conjunction with the Series D Preferred financing,
these warrants were exchanged for new warrants to purchase 791,044 shares of common  stock at an
exercise price of $4.08 per share. During fiscal 2007, all 791,044 warrants  were exercised in cashless
exercises, resulting in the issuance of 496,839 shares of the Company’s common stock.

In connection with the May 2002 sale of common stock to private investors, the Company issued

warrants to purchase up to 3,208,333 shares of common stock at a price of $13.20 per share. In August
2003, the warrants were canceled, and new warrants were issued to purchase 1,152,665 shares at an
exercise price of $9.76 per share, due to the impact of the Series D Preferred financing on the
warrants’ anti-dilution provisions. In January 2004, warrants to purchase 129,191 shares of common
stock were exercised in a cashless exercise, resulting in the issuance of 17,922 shares of common stock.
During fiscal 2007, the remaining 1,023,474 warrants were exercised in a cashless exercise, resulting in
the issuance of 286,204 shares of the Company’s common stock.

In connection with the August 2003 Series D Preferred financing, the  Company issued  warrants
with seven-year lives to purchase 7,267,286 shares of common stock at an exercise price of $3.33 per

share. In July 2006, 6,006,006 warrants were exercised in a cashless exercise, resulting in the  issuance  of
4,369,336 shares of the Company’s common stock. As of June 30, 2007, warrants  to  purchase 1,261,280
shares of common stock at an exercise price of $3.33 were exercisable. Subsequent to year-end, in
November 2007, warrants to purchase 630,640 shares of common stock were exercised in a cashless
exercise, resulting in the issuance of 500,203 shares of  common stock.

(b) Stockholder Rights Plan

During fiscal 1998, the Board of Directors of the Company adopted a Stockholder  Rights

Agreement (the Rights Plan) and distributed one Right for each outstanding share of Common Stock.
The Rights were issued to holders of record of Common Stock  outstanding on  March 12,  1998. Each
share of Common Stock issued after March 12, 1998 will also include one Right, subject to certain
limitations. Each Right when it becomes exercisable will initially entitle the registered holder to
purchase from the Company one one-hundredth (1/100th) of a share of Series A Preferred Stock at  a
price of $175.00 (the Purchase Price).

The Rights will become exercisable and separately transferable when the Company  learns that any
person or group has acquired beneficial ownership of 15% or  more of the outstanding Common Stock
or on such other date as may be designated by the Board of Directors following the  commencement of,
or first public disclosure of an  intent to commence, a tender or exchange  offer for  outstanding
Common Stock that could result in the offeror becoming the beneficial owner of 15% or more of the
outstanding Common Stock. In such circumstances, holders of the Rights will be entitled  to  purchase,
for the Purchase Price, a number of hundredths of a share  of  Series A Preferred Stock equivalent to
the number of shares of Common Stock (or, in certain circumstances, other equity securities) having a
market value of twice the Purchase Price. Beneficial holders of 15% or more  of  the outstanding
Common Stock, however, would not be entitled to exercise their Rights in such circumstances. As a
result, their voting and equity interests in the Company would be substantially diluted if  the Rights
were to be exercised.

The Rights expire in March 2008, but may be redeemed earlier by the Company at  a price of $.01

per Right, in accordance with the provisions of the Rights Plan.

The Company amended the Rights Plan in June 2003 so that the terms of the Rights Plan would

not be applicable to the securities issued as part of the Series D preferred financing or to any securities
issued in the future pursuant to the preemptive rights granted as part of this financing.

Upon customer payment of certain foreign receivables, withholding taxes are withheld by
customers and remitted to local tax authorities. Under current U.S. tax law, these withholding taxes
may be creditable against U.S. taxes payable subject to certain limitations. The withholding taxes are
included in the foreign tax provision as they are withheld and remitted. Utilization of the taxes as
foreign tax credits is recorded as a reduction of the domestic tax expense in the  period it is more  likely
than not that these deferred tax assets will be realized. The Company has  recorded a full  valuation
allowances against these credits, and will recognize the benefit of these credits only when it is more
likely than not that these deferred tax assets will be realized.

During the years ended June 30, 2006 and 2007, the Company utilized tax net operating loss

carryforwards to reduce the current provision by $6.4 million and $16.1 million, respectively. As of
June 30, 2007, the Company has generated U.S. federal net operating loss (NOL) carryforwards of
$38.2 million, which includes $36.9 million of stock compensation tax deductions in excess of book
compensation expense. The Company records deferred tax assets for excess tax benefits only when such
deductions reduce taxes payable as determined on a ‘‘with and without’’ basis. Accordingly, this NOL
will reduce federal taxes payable if realized in future periods, but NOL related to such benefits are not
included in the table above. Upon realization of the NOL generated by these excess tax benefits, the

F-37

ASPEN TECHNOLOGY, INC. AND  SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(11) Income Taxes (Continued)

benefit is credited to additional paid-in capital and not as a reduction to the income tax provision. The
Company has foreign loss carryforwards of $18.8 million which expire beginning in 2008 through no
expiration date.

The Company has determined that it underwent an ownership change (as  defined under

section 382 of the Internal Revenue Code of 1986, as amended) during the year ended June 30, 2004.
As such, the utilization of the Company’s federal NOLs and tax credits is limited. Moreover, an
ownership change also occurred under the laws of certain states and foreign countries in which the
Company has generated NOLs and tax credits. Accordingly, these NOL and tax credits will also  be
limited under rules similar to those of section 382. These limitations  impact  the amount of NOL, if any,
that may be utilized in a given year. The full amount of the federal NOL carryforward as  of June 30,
2007 is subject to these limitations and would be limited to an approximate $7 million per year
limitation. The federal NOLs as of June 30, 2007 begin to expire in 2021.

The Company also has foreign tax credits (FTCs) and research and development credits, and
foreign tax operating loss carryforwards. These benefits are subject to a full valuation allowance and
will reduce tax expense in the period that they are realized or the valuation allowance is removed if
realization is considered more likely than not. The tax credits  and  foreign NOL carryforwards expire at
various dates from 2008 through 2027.

The Company’s U.S. and foreign tax returns are subject to periodic compliance examinations by

various local and national tax authorities through periods defined by tax codes in the applicable
jurisdiction. The Company’s operating entities in Canada are subject to audit from year 2000, in the
UK from 2006, and other international subsidiaries from 2002 through 2007. The Company’s  U.S. open
tax periods are from 2004 through 2007, although examination may extend back to the period that such
losses were generated as a result of the utilization and adjustments to the Company’s tax loss
carryforwards.

In connection with examinations of tax filings, tax contingencies can arise from differing

interpretations of applicable tax laws and regulations relative to the amount,  timing or proper inclusion
or exclusion of revenues and expenses in taxable income or loss. For periods  that  remain subject  to
examination, the Company has asserted and unasserted potential assessments that  are subject to final
tax settlements. As of June 30, 2007, the Company has accrued $22.0 million related  to  potential  tax,
penalties, and interest, based on management’s estimate of adjustments  to  previously  filed tax returns
for the open audit periods in all jurisdictions. Of this amount, the Company has potential foreign  tax
obligations related to specific issues in international locations and has accrued  $19.4  million related to
these matters as of June 30, 2007. Total domestic tax reserves are $2.6 million. The ultimate  amount of
taxes due for these periods will not be known until examinations are completed or the audit periods
are closed and settled. While the Company believes it has adequately provided for all probable
exposures, the ultimate amounts concluded with tax authorities could be different than its accrued
position. Accordingly, adjustments for domestic and foreign tax contingencies could be recorded in the
future as revised estimates are made or the underlying matters are settled or otherwise resolved, and
such adjustments could be material.

The Company has an ongoing audit for fiscal 2000 in Canada. The Canada Revenue Agency, or
CRA, has proposed an increase to taxable income of CAD 13.6 (USD $12.8) million  for fiscal  2000,
primarily related to transfer pricing matters. The Company has reviewed the basis of the CRA
proposed adjustment and believes that it was based on incorrect information. The Company has

F-38

ASPEN TECHNOLOGY, INC. AND  SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(11) Income Taxes (Continued)

proposed to CRA an increase of CAD 3.6 (USD $3.4) million in taxable income and has accrued taxes
payable, including estimated interest and penalties, of $2.7 million as of June 30, 2007, an  increase of
$1.6 million in 2007. In addition, the Company has other uncertain tax positions for other open  audit
periods in Canada. The uncertain tax positions primarily relate to the application of the  Company’s
transfer pricing policies for transactions among its consolidated subsidiaries,  failure to properly account
for deemed dividends due to the lack of timely settlement of intercompany transactions, accounting for
revaluation of foreign denominated transactions, and other positions for  which it expects  to  file
amended tax returns pursuant to voluntary disclosure discussions with CRA.  The Company has
recorded estimated tax obligations, including interest and penalties when applicable,  associated with
these open audit periods.

(12) Operating Leases

The Company leases its facilities and various office equipment under noncancelable operating

leases with terms in excess of one year. Rent expense charged to operations was approximately
$9.3 million, $7.5 million, and $7.9 million for the years ended June 30,  2005, 2006  and 2007,
respectively. Future minimum lease payments under these  leases and scheduled sublease  payments as of
June 30, 2007 are as follows (in thousands):

Due to various restructuring activities (See Note 3) the Company has vacated certain  of its  leased

space and is subleasing a portion of this space. The scheduled  sublease payments are  listed above.

The Company has issued approximately $6.2 million of standby letters of credit in connection with

certain facility leases that expire through 2016.

In May 2007, the Company entered into a lease agreement with respect to office space in
Burlington, Massachusetts. Commencing September 1, 2007, the Company moved its principal
corporate offices to this location and occupied 60,177 square feet of space. The initial term of the lease
commenced with respect to (a) 31,174 square feet of leased premises on September 1, 2007, (b) an
additional 18,947 square feet on October 1, 2007 and (c) an additional 10,056 square feet on January 1,
2008. The initial term of the lease will expire seven years and four months following the term
commencement date for the third phase of the leased premises. Subject to the terms and conditions of
the lease, the Company may extend the term of the lease for two successive terms of five years each at
95% of the then market rate. Under the lease, the Company will pay additional rent for its
proportionate share of operating expenses and taxes. Future minimum lease payments under this lease
of $10.9 million are included in the table above.

On September 5, 2007, the Company entered into an additional sublease agreement related to its

former office space in Cambridge, Massachusetts, effective  October 1, 2007 for  approximately  50,000
square feet that expires on September 30, 2012. This new sublease agreement represents $5.5 million of
scheduled sublease payments not included in the above table.

Effective September 1, 2007, the landlord terminated a portion of the Company’s lease in
Houston, Texas with respect to approximately 14,000 square  feet of the original leased space. This
termination agreement has not been included in the above table and represents future reductions of
$2.6 million in lease payments.

(13) Commitments and Contingencies

(a) FTC  settlement and Related Honeywell  Litigation

In December 2004, the Company entered into a consent decree with the  Federal Trade

Commission, or FTC, with respect to a civil administrative complaint filed by the FTC in August 2003
alleging that the Company’s acquisition of Hyprotech in May 2002 was anticompetitive  in violation of
Section 5 of the Federal Trade Commission Act and Section  7 of the Clayton Act. In connection with
the consent decree, the Company entered into an agreement with Honeywell International, Inc.  on
October 6, 2004 (‘‘Honeywell Agreement’’), pursuant to which the Company transferred its operator
training business and its rights to the intellectual property of various  legacy Hyprotech products.  In
addition, the Company transferred its AXSYS product line to Bentley Systems, Inc.

On December 23, 2004, the Company and its subsidiaries completed the transactions with

Honeywell contemplated by the Honeywell Agreement. Under the terms of the transactions:

• the Company agreed to a cash payment of  approximately $6.0  million  from Honeywell  in
consideration of the transfer of the Company’s operator training services business, the
Company’s covenant not-to-compete in the operator training business until the third anniversary
of the closing date, and the transfer of ownership of the intellectual property of the  Company’s
Hyprotech engineering products, $1.2 million of which is subject to holdback and may be
released upon the resolution of any adjustments for uncollected billed  accounts receivable and
unbilled accounts receivable.

• the Company transferred and Honeywell assumed,  as of the closing date,  approximately

$4 million in accounts receivable relating to the operator training business; and

• the Company entered into a two-year  support agreement with Honeywell under which  the
Company agreed to provide Honeywell with source code to new releases of the Hyprotech
products provided to customers under standard software maintenance services agreements.

The Honeywell transaction resulted in a deferred gain of $0.2 million, which was amortized over
the two-year life of the support agreement, and is subject to a potential increase of $1.2 million upon
resolution of the holdback payment.

The Company is subject to ongoing compliance obligations under the FTC consent decree. The

Company has been responding to requests by the Staff of the FTC for information relating to the
Staff’s investigation of whether the Company has  complied with the  consent decree. In  addition,  the
FTC is considering whether to commence litigation against the Company arising from the Company’s
alleged failure to comply with certain aspects of the decree. If the FTC or a court were to determine

F-40

ASPEN TECHNOLOGY, INC. AND  SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(13) Commitments and Contingencies (Continued)

that the Company has not complied with its obligations  under the consent decree, the Company could
be subject to one or more of a variety of penalties, fines, injunctive relief and other remedies, and
associated legal fees and expenses, any of which might materially limit the Company’s ability to operate
under its current business plan and might have a material adverse  effect  on the  Company’s  operating
results and financial condition.

In March 2007, the Company was served with a complaint and petition to compel arbitration filed

by Honeywell in New York State Supreme Court. The complaint alleges  that the Company failed to
comply with its obligations to deliver certain technology under the Honeywell Agreement referred to
above, that the Company owes approximately $800,000 to Honeywell under the Honeywell Agreement,
and that Honeywell is entitled to some portion of the $1.2 million  retained by Honeywell under the
holdback provisions of the Honeywell Agreement, plus unspecified monetary damages arising from
contracts assumed thereunder. The Company believes the claims to be without merit and intend to
defend the claims vigorously, and to pursue payment of  the $1.2 million retained under  the holdback
provisions of the Honeywell Agreement. However, it is possible that  the resolution of the claims may
have an adverse impact on the Company’s financial position and results of operations.

(b) Other Litigation

SEC action and U.S. Attorney’s office criminal complaint

In January 2007, the SEC filed a civil enforcement action in Massachusetts federal  district court

alleging securities fraud and other violations against three of the Company’s  former executive officers,
David McQuillin, Lisa Zappala and Lawrence Evans, arising out of six transactions in 1999 through
2002 that were reflected in the Company’s originally filed consolidated financial statements  for fiscal
2000 through 2004, the accounting for which was restated in March 2005. The  Company and  each of
these former executive officers received ‘‘Wells Notice’’ letters of possible enforcement proceedings by
the SEC. On the same day the SEC complaint was filed, the U.S.  Attorney’s Office  for the Southern
District of New York filed a criminal complaint against David McQuillin alleging criminal  securities
fraud violations arising out of two of those transactions. Mr. McQuillin pled guilty in  March 2007 and
was sentenced in October 2007.

On July 31, 2007, the Company entered into a settlement order with  the  SEC resolving the  Wells

Notice the Company received. Under the settlement order, the Company agreed to cease and desist
from violations of certain provisions of the federal securities laws, and to comply with certain
undertakings. No civil penalty was assessed by the SEC in connection with that settlement order, and
the Company has not admitted or denied any wrongdoing in connection with that settlement order.

The SEC enforcement action and the U.S. Attorney’s Office criminal action do not involve the
Company or any of its current officers or directors. The Company can provide no assurance, however,
that the U.S. Attorney’s Office,  the SEC or another regulatory agency  will not bring an  enforcement
proceeding against the Company, its officers and employees or additional former officers and
employees based on the consolidated financial statements that were restated in March 2005. The
Company continues to cooperate with the SEC and the U.S. Attorney’s Office.

Class action and opt-out claims

In March 2006, the Company settled class action litigation, including related derivative claims,
arising out of the restated consolidated financial statements that include the periods referenced in the
SEC enforcement action and the criminal complaint discussed above. Members of the class who  opted
out of the settlement (representing 1,457,969 shares of common stock,  or less  than 1%  of  the shares
putatively purchased during the class action period) may bring or have brought their own state  or
federal law claims against the Company, referred to as opt-out claims.

Pursuant to the terms of the Class Action settlement, the Company paid $1.9  million  and its
insurance carrier paid $3.7 million into a settlement fund for a total of $5.6 million. The Company’s
$1.9 million payment was recorded in general and administrative expenses  in the  quarter ended
September 30, 2005. All costs of preparing and distributing notices to members of the Class and
administration of the settlement, together with all fees and expenses awarded to plaintiffs’ counsel and
certain other expenses, will be paid out of the settlement fund, which will be maintained by an escrow
agent under the Court’s supervision.

Separate actions have been filed on behalf of the holders of approximately  1.1 million shares who

either opted out of the class action settlement or were not covered by that settlement. The  claims in
those actions include claims against the Company and one or more of its former officers alleging
securities and common law fraud, breach of contract, statutory treble damages, deceptive practices
and/or rescissory damages liability, based on the restated results of one or more  fiscal  periods included
in its restated consolidated financial statements referenced in the class action. Those  actions are:

• Blecker,  et al. v. Aspen Technology, Inc., et al., filed on June 5, 2006 in the Business Litigation
Session of the Massachusetts Superior Court for Suffolk County and docketed as Civ. A.
No. 06-2357-BLS1 in that court, which is an ‘‘opt out’’ claim asserted  by  persons who received
248,411 shares of the Company’s common stock in an acquisition;

of the Massachusetts Superior Court for Suffolk County and docketed as Civ. A.

which is a claim asserted by persons who purchased 566,665 shares of the Company’s common
stock in a private placement.

The damages sought in these actions total more than $20 million, not including claims for treble
damages and attorneys’ fees. If these actions are not dismissed or settled on terms acceptable to the
Company, the Company plans to defend the actions vigorously. The Company can provide no assurance
as to the outcome of these opt-out claims or the likelihood of the filing of additional opt-out claims,
and these claims may result in judgments against the Company for significant damages. Regardless of
the outcome, such litigation has resulted in the past, and may continue to result in the future, in
significant legal expenses and may require significant attention and resources of management, all of
which could result in losses and damages that have a material adverse effect on the Company’s
business.

On September 6, 2006, the Company also announced that, in connection with the  preparation  of
financial statements for the fiscal year-ended June 30, 2006, a subcommittee of independent directors
was appointed to review the Company’s accounting treatment for stock option grants for prior  years.
Following that announcement, the Company  and certain  of its officers and directors were named
defendants in a purported federal securities class action lawsuits filed in Massachusetts federal district
court, alleging violations of the Exchange Act and claiming material misstatements concerning its
financial condition and results. In response to the Company’s motion to dismiss  the complaint, the
parties stipulated to voluntary dismissal of the plaintiff’s claims with prejudice on September 26,  2006
without any payment by the Company.

Derivative suits

The Company may be named as a defendant in securities litigation or  derivative lawsuits by
current or former stockholders based on the restated consolidated financial statements. Further, the
Company may be subject to claims relating to adverse tax consequences with respect  to  stock options
covered by the restatement. Defending against potential claims will likely require significant attention
and resources of management and could result in significant legal expenses.

On December 1, 2004, a derivative action lawsuit captioned Caviness v. Evans, et al., Civil Action
No. 04-12524, referred to as the Derivative Action,  was filed in Massachusetts federal district court as a
related action to the first filed of the putative class actions subsequently consolidated into  the class
action described above. The complaint, as subsequently amended, alleged, among other things, that the
former and current director and officer defendants caused the Company to issue  false and misleading
financial statements, and brought derivative claims for the following: breach of fiduciary duty for
insider trading, breach of fiduciary duty, abuse of control, gross mismanagement, waste of corporate
assets and unjust enrichment. On August 18, 2005, the court granted the defendants’  motion to dismiss
the Derivative Action for failure of the plaintiff to make a pre-suit demand on the  board  of  directors to
take the actions referenced in the Derivative Action complaint, and the Derivative Action was
dismissed with prejudice.

On April 12, 2005, the Company received a letter on behalf of another purported stockholder,

demanding that the board take actions substantially similar to those referenced in the Derivative
Action. On February 28, 2006, the Company received a letter on behalf of the  plaintiff  in the
Derivative Action, demanding that they take actions  referenced in the  Derivative  Action complaint.  The
board responded to both of the foregoing letters that the board has taken the letters under advisement
pending further regulatory investigation developments, which the board continues to monitor  and with
which the Company continues to cooperate. In its responses, the board also requested confirmation of
each person’s status as one of the Company’s stockholders and, with respect to the most recent letter,
also referred the purported stockholder to the March 2006 settlement in the class action.

On September 27, 2006, a derivative action  lawsuit was filed  in  Massachusetts Superior Court
captioned Rapine v. McArdle, et al., Civil Action No. 06-3455. The complaint alleged, among other
things, that the former and current director and officer defendants ‘‘authorized, modified, or failed to
halt backdating of stock options in dereliction of their fiduciary duties to the Company as directors and
officers.’’ On October 16, 2006, defendants removed  the action to Massachusetts federal district court
and moved to dismiss the complaint. On October 30, 2006, the purported stockholder plaintiff filed an
amended complaint, asserting derivative claims for breach of fiduciary duty; unjust enrichment; insider

trading; violations of Sections 10(b), 14 and 20(a) of the Securities Exchange Act of 1934; and
corporate waste. In October 2007, the court closed this action and  consolidated the action with the
Risberg case referenced below, which  was subsequently dismissed.

In February 2007, a derivative action lawsuit was filed in Massachusetts federal district court
captioned Risberg v. McArdle et al., 07-CV-10354. The plaintiff purports  to  bring a derivative action on
behalf of the Company alleging, among other things, that several former and current directors  and
officer defendants authorized, were aware of, or received ‘‘backdated’’ stock options. The complaint
asserts claims for breach of fiduciary duty; unjust enrichment; violations of Sections 10(b), 14 and 20(a)
of the Securities Exchange Act of 1934; corporate waste; and  breach of contract. In January 2008, the
court granted defendants’ motion to dismiss this action for failure of the plaintiff to make  a pre-suit
demand on the Company’s board of directors, and judgment on the order of dismissal was  entered in
favor of all defendants.

KBC settlement

On October 1, 2004, the Company, together with its subsidiaries AspenTech, Inc. and Hyprotech

Company, entered into a Settlement Agreement with KBC Advanced Technologies Plc, KBC Advanced
Technologies Inc. and AEA Technology  Plc. Pursuant to the  settlement agreement, the  parties agreed
to settle (1) the arbitration proceedings in England relating to a contract dispute involving the parties
and (2) the legal proceedings filed by KBC in state district court in Houston, Texas against the
Company and Hyprotech Company.

As part of the settlement, KBC recognized the Company’s right to develop, market and license

Aspen RefSYS, and the Company recognized KBC’s  right to develop, market and license
HYSYS.Refinery, their respective refinery-wide simulation products.  The  Company licensed
commercial, object code, copies of Aspen HYSYS, Aspen PIMS, and Aspen Orion to KBC for use as
part of KBC’s consulting services business, without the  right  to  sublicense. In addition, the Company
paid KBC $3.75 million in lieu of costs incurred in the dispute. This charge was recorded  in fiscal 2005
in general and administrative expenses.

Other

The Company is currently defending claims that certain of its software products and

implementation services have failed to meet customer expectations. On May 11, 2007, one of the claims
resulted in an arbitration award against the Company in the amount of $1.4 million. As of June  30,
2007, the Company has accrued the amount of the arbitration award. The Company is defending other
claims in excess of $5 million, primarily consisting of a customer claim, as well as other general
commercial claims. Although the Company believes the remaining claims to be without merit, and is
defending the claims vigorously, the results of litigation and claims cannot be predicted with certainty,
and unfavorable resolutions are possible and could, depending on the amount and timing of any
outcome, materially affect the Company’s results of operations, cash flows or financial position. In
addition, regardless of the outcome, litigation could have an adverse impact on the Company because
of defense costs, diversion of management resources and other factors.

(c) Other Commitments and Contingencies

The Company has entered into an employment agreement with  its president and chief executive
officer providing for the payment of cash and other benefits in certain situations of his voluntary or
involuntary termination, including following a change in control. Payment under this agreement would
consist of a lump sum equal to approximately two times (1) his  annual  base  salary plus (2)  the average
of his annual bonus for the three preceding fiscal years. The agreement also provides that the payments
would be increased in the event that it would subject him to excise tax as a parachute  payment under
the Internal Revenue Code. The increase would be equal  to  the additional tax liability imposed on him
as a result of the payment.

The Company has entered into agreements with other executive  officers,  providing for severance

payments in the event that the executive is terminated by the Company other than for cause. Payments
under these agreements consist of continuation of base salary  for a  period of 12 months.

In connection with the audit committee’s review of the Company’s accounting treatment of all

stock option grants since the Company’s initial public offering in fiscal 1995 through fiscal 2006, the
Company recorded estimated payroll withholding tax charges of $1.9 million and an estimated liability
of $1.0 million to assist affected employees who are subject to an excise tax on the value of the options
in the year in which they vest, for a total estimated liability of $2.9 million recorded in June 2006.
These liabilities were $0.5 million as of June 30, 2007 as a result of payments of $0.7 million and
changes in estimates of $1.7 million of the total expected costs to be incurred.

The Company maintains strategic alliance relationships with third  parties,  including resellers,
agents and systems integrators (each an Agent) that market, sell and/or integrate the Company’s
products and services. The cessation or termination of certain relationships, by the Company  or an
Agent, may subject the Company to material liability and/or expense. This material liability and/or
expense includes potential payments due upon the termination or  cessation  of  the relationship by either
the Company or an Agent (which may be triggered by a change in control of either party), costs related
to the establishment of a direct sales presence or development of a new Agent in  the territory. No such
events of termination or cessation have occurred through June 30, 2007. The Company is not able to
reasonably estimate the amount of any such liability and/or expense if such event  were to occur,  given
the range of factors that could affect the ultimate determination of the liability  including possible
claims related to the validity of the arrangements or contract terms. Actual payments from an event
could be in the range of zero to $30.0 million dollars. If the Company reacquires the territorial rights
for an applicable sales territory and establishes a direct sales presence, future commissions otherwise
payable to an Agent for existing customer maintenance contracts and other intangible assets may be
assumed from the Agent. If any of the foregoing were to occur, the Company may be subject to
litigation and liability such that its operating results, cash flows and financial condition could be
materially and adversely affected.

(14) Retirement and Profit Sharing Plans

The Company maintains a defined contribution retirement plan under Section 401(k) of the
Internal Revenue Code covering all eligible employees, as defined. Under the plan, a participant  may
elect to defer receipt of a stated percentage of his or her compensation, subject to limitation under the
Internal Revenue Code, which would otherwise  be  payable to the participant for any  plan year. The
Company may make discretionary contributions to this plan, including making matching contributions

F-45

ASPEN TECHNOLOGY, INC. AND  SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(14) Retirement and Profit Sharing Plans  (Continued)

up to a maximum of 6% of an employee’s pretax contribution. During the fiscal  years  ended June 30,
2005, 2006 and 2007, the Company made matching contributions of approximately $1.0  million,
$0.8 million and $0.8 million, respectively. These contributions, which vested immediately,  were
expensed in each respective year.

(15) Joint Ventures and Other Investments

In November 2000, the Company invested $0.6 million in a global chemical business-to-business

e-commerce company supporting major chemical companies in Asia. This  investment entitles  the
Company to a minority interest in this company and is accounted for using the cost  method and,
accordingly, is being valued at cost unless an other-than-temporary impairment in its value  occurs.  As
of June 30, 2007, the Company has determined that an other than temporary impairment  has not
occurred. No impairments have been recognized through June 30, 2007.  This investment  is included in
other assets in the accompanying consolidated balance sheet.

(16) Segment and Geographic Information

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 measurement of the controllable margin for the  license operating segment was changed in
2007 to include a greater allocation of expenses from unallocated costs to controllable  expenses for  that
operating segment. This change conformed to management’s current approach  of  cost allocation for
internal reporting purposes. All periods presented have been restated to conform to management’s
current measurement approach.

The Company has three operating segments: license, consulting services and  maintenance and
training. The chief operating decision maker assesses financial performance and allocates resources
based upon the three lines of business.

The license line of business is engaged in the development and licensing of software. The
consulting services line of business offers implementation, advanced process control, real-time
optimization and other consulting services in order to provide its customers with complete solutions.
The maintenance and training line of business provides customers with a wide range of support  services
that include on-site support, telephone support, software updates and various forms of training on how
to use the Company’s products.

The accounting policies of the operating segments are the same as those described in the summary

of significant accounting policies. The Company does not track assets or capital expenditures by
operating segments. Consequently, it is not practical to show assets, capital expenditures, depreciation
or amortization by operating segments.

During the years ended June 30, 2005, 2006 and 2007 there were no customers that individually

and $2.8 million that reside in other geographic locations as of June 30, 2007.

(17) Restatement of Consolidated Financial Statements

Subsequent to the issuance of the Company’s consolidated financial statements for  the year  ended

June 30, 2006 (as previously restated), the Company identified errors related to the accounting for sales
of customer installment and trade receivables to financial institutions or  unconsolidated special purpose
entities, which the Company refers to as ‘‘receivable sale facilities.’’ The sales of receivables were
designed to meet ‘‘true sale’’ criteria for legal and accounting purposes. The transferred receivables
serve as collateral under the receivable sales facilities and limited recourse exists against the  Company
in the event that the underlying customer does not pay. These transactions historically  had been
accounted and reported as sales  of assets for accounting purposes, rather than as  secured borrowings.
As further described below, however, the Company should  not  have derecognized the receivables and
should have recorded the cash received from the transfer of such assets as a secured  borrowing  in the
Company’s consolidated balance sheet, as it effectively retained control of these assets for accounting
purposes. As further discussed below, the Company also identified other errors related to revenue
recognition, income tax accounting, and classification of preferred stock dividends and accretion.

The Company effectively retained control for accounting purposes of the transferred assets as a

result of engaging in new transactions with its customers to sell additional software and/or extend the
terms of existing license arrangements, which were the basis for these installments receivable. The new
transactions would sometimes consolidate the remaining balance of the outstanding receivables with
additional amounts due under the new or extended software license arrangement. Some receivable sale
facilities allowed for this consolidation, subject to a limit, which was exceeded. Other receivable sale
facilities did not allow for this method of consolidation. Accordingly, the amount and/or method of
consolidation of these receivables resulted in the lack of legal isolation of the assets from the Company,
which is one of the requirements to achieve and maintain sale accounting treatment under SFAS
No. 140. The Company believes that for accounting purposes, it retained control of the receivables
transferred to the receivable sales facilities for each of the years in the three-year period ended

F-48

ASPEN TECHNOLOGY, INC. AND  SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(17) Restatement of Consolidated Financial Statements (Continued)

June 30, 2007 and that none of the sales of receivables during this period qualified for sale accounting
treatment under the provisions of SFAS No. 140. This accounting conclusion does not alter the
arrangements with the Company’s customers, and the Company does not believe that the accounting
conclusion has changed its relationship with the financial institutions, including the  limited  recourse
that such financial institutions have against the Company  beyond the transferred receivables.

The Company’s previous accounting treatment was to inappropriately  account for these
transactions as sales of assets. Accordingly, under its previous accounting treatment, the Company
immediately recognized any gains and losses upon the transfer of  assets and then recorded a ‘‘retained
interest in sold receivables’’ for its continuing interest, if any, which was  initially recorded at  the
estimated fair value. The retained interest in sold receivables was subject to periodic accretion of this
interest (recorded through interest income) through the term of the respective arrangement. No
recognition of the transferred receivables or any debt obligation was recognized for these transactions.

To correct these errors, the Company has recorded the transferred receivables,  which are reported

as ‘‘collateralized receivables’’ on the Company’s consolidated balance sheet,  and  a secured debt
obligation for the amount of cash received from the receivable sale facilities. There are no longer gains
and losses recognized upon the transfer of these assets and any costs incurred have now been recorded
as debt issuance costs. The Company now recognizes interest income from the retained installments
receivable and interest expense on the secured borrowing. The previous accounting for  the retained
interest in the transferred installments receivables, including the accretion included  in interest income,
has been eliminated as the entire interest in the receivables has  been included in the Company’s
consolidated balance sheet. Bad debt provisions related to the transferred receivables are now reflected
in the Company’s consolidated statements of operations. The Company has also recorded  the currency
exchange gains or losses on installments receivable that were  previously  not  recorded. The funding
received from the receivable sales  facilities was previously recorded as  cash flows from  operations in
the Company’s consolidated statements of cash flows. The Company has corrected the  presentation to
include the proceeds from and repayments of the secured borrowings  as  components of cash flows from
financing activities in the consolidated statements of cash flows.  Repayments of secured borrowings and
operating cash flows from collateralized receivables are recognized  upon customer payment  of  amounts
due.

In addition, the Company identified other errors related to previously reported financial statements

in the course of preparing the consolidated financial statements for  the year ended June 30,  2007.
These errors relate to the timing of revenue recognition, corrections to the Company’s  income tax
accounting, classification of preferred stock dividends and accretion and other items. Errors in the
timing of revenue recognition primarily relate to the inappropriate application of SOP No. 97-2 for
certain arrangements that bundled software licenses with services. For these bundled  arrangements, the
Company determined that the service element could not be accounted for separately from the software
licenses. The Company had deferred revenue  recognition  related to the license component until the
services arrangements were complete, instead of recognizing revenue under the arrangements as
services were performed. In other arrangements, the Company determined that service revenue was
recognized prior to the delivery of the software license, and the Company did not have VSOE of fair
value for the undelivered license or the price of the arrangement was not fixed and determinable. In
addition, revenue was recognized in fiscal 2005 where collection was not probable as the customer did
not have the ability to pay until the software was implemented for an end user or specified upgrades
were provided. Further, a change in the terms of an  agreement  occurring in fiscal 2006 was  not

F-49

ASPEN TECHNOLOGY, INC. AND  SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(17) Restatement of Consolidated Financial Statements (Continued)

previously recorded and should have been reflected in fiscal 2006. The Company has corrected these
errors and recognized revenue over the period the services were performed for these bundled
arrangements or when the criteria for revenue recognition were met.

The Company also identified errors in its historical income tax accounting for  certain international

tax obligations, primarily arising from errors in the application  of  the Company’s transfer pricing
policies for transactions among consolidated subsidiaries, failure to properly  account for deemed
dividends from the Company’s consolidated subsidiaries as a result of the lack of settlement of
intercompany transactions, errors in the accounting for revaluation of foreign denominated transactions,
and other errors. The Company has corrected the calculation of its tax provisions for these obligations
in the applicable year, including recognition of interest and  penalties attributable to the adjusted  tax
provisions.

In addition, in the calculation and disclosure of deferred tax balances, the majority of which are
subject to a full valuation allowance, errors were identified for the book or tax accounting treatment for
certain components of these balances and resulted in the incorrect disclosure of the Company’s
deferred taxes and the related offsetting valuation allowance within  the income tax  footnote.  These
disclosures, along with any changes in balances reflected, are being restated as of June 30, 2006  in the
tax footnote. The primary components which are being restated are the federal  and state loss
carryforwards, foreign tax credits, and other errors in the calculation of deferred tax balances. In
addition, the disclosure of the tax net operating loss should have excluded all excess tax benefits arising
from the stock compensation deductions, which upon realization, would be reflected in additional
paid-in capital. As a result, the disclosure of domestic tax loss carryforwards has been reduced  by
$32.4 million and foreign tax credit carryforwards have increased by $19.0 million as of June 30,  2006.
Other net deferred tax balances were increased by a total of  $12.9 million. As these deferred tax assets
had and continue to have a full valuation allowance, corrections to the disclosure of the  Company’s
deferred taxes and the related offsetting valuation allowance had an immaterial  impact  on the
Company’s consolidated balance sheets, statements of operations, and statements of cash  flows.

The Company also identified that dividends and accretion on outstanding preferred stock has  not

been properly classified within its stockholders’ equity accounts. As the Company  has been in an
accumulated deficit position, the dividends and accretion on preferred stock should have been classified
as a reduction in additional paid-in capital as opposed to increasing the accumulated deficit. As a result
of this error, additional paid-in capital was overstated and accumulated deficit was overstated as  of
June 30 2004, 2005, and 2006 by $28.3 million, $42.8 million, and $58.1 million, respectively.

In order to correct the errors described above, the Company has restated its consolidated balance

sheet as of June 30, 2006 primarily to reflect (a) the recording of $211.3 million in collateralized
receivables, (b) the related recording of $182.4 million in secured borrowings supported by this
collateral, (c) the elimination of the $19.0 million in retained interest in sold receivables, (d) additional
taxes payable of $15.1 million and other accrued liabilities of $2.3 million and (e) $58.1 million
reclassification between additional paid-in capital and accumulated deficit. The Company has restated
its consolidated statements of operations for the years ended June 30, 2005 and 2006 primarily to
reflect (a) additional interest income related to the collateralized receivables of $12.8 million in the

To Our Shareholders:

I am pleased to report that Fiscal 2007 was a record year of profitability for AspenTech®. Our operating

performance in Fiscal 2007 continued the turnaround in the company’s operating performance that

started in Fiscal 2006. Our success was due to continued strength in our core markets, the adoption of

integrated aspenONE™ solutions by our customers, and solid execution by our employees.

Fiscal 2007 was also marked by financial reporting delays, which ultimately resulted in the delisting of

our common stock from the NASDAQ Global Market. Although we were pleased with our operating

performance, the financial reporting delays and their overshadowing of our strong operating

performance have been a disappointment. We have been working diligently to become current in our

financial reporting. In April 2008 we completed and filed our Fiscal 2007 financial statements,

restatement of past years’ financial statements, and our Fiscal 2008 first quarter results. In addition,

we began working on the Fiscal 2008 second and third quarter financials, and KPMG began its

engagement as our new independent registered public accounting firm. We appreciate your patience

and support as we finish this work. On an operational level, we continue to improve and have

significant opportunity over the long term.

Actual results may vary significantly from
AspenTech’s expectations based on a number of
risks and uncertainties, including, without
limitation: AspenTech’s plan to improve
operational performance may not be
implemented effectively; AspenTech has
identified material weaknesses in its internal
controls with respect to software license revenue
recognition and other matters, that, if not
remedied effectively, could result in material
misstatements; AspenTech may incur substantial
damages and expenses as the result of pending
and future securities litigation and government
investigations, including securities litigation
based on the restatements of the company’s
financial statements as well as any future action
associated with a determination that the
company has failed to comply with its existing
consent decree with the Federal Trade
Commission; AspenTech’s lengthy sales cycle
makes it difficult to predict quarterly operating
results; fluctuations in AspenTech’s quarterly
operating results; AspenTech’s dependence on
customers in the cyclical chemicals,
petrochemicals and petroleum industries; the
possibility of new accounting standards or the
interpretation of existing accounting standards
affecting our financial results; AspenTech’s ability
to raise additional capital as required; intense
competition; AspenTech’s need to develop and
market products successfully; reliance on
relationships with strategic partners; challenges
associated with international operations; risks
associated with AspenTech’s delisting from The
Nasdaq Stock Exchange and the trading of
AspenTech’s common stock over the counter;
and other risk factors described from time to time
in AspenTech’s periodic reports filed with the
Securities and Exchange Commission.
AspenTech cannot guarantee any future results,
levels of activity, performance, or achievements.
AspenTech expressly disclaims any current
intention to update forward-looking statements
after the date of this press release.
