PART I



|ITEM 1. | BUSINESS
|------- | --------

General

We are a leader in the development, marketing and support of enterprise simulation solutions, including simulation software and related services. For over
40 years, our solutions have allowed manufacturing and technology companies, as well as universities and research institutions around the world to accurately validate how their designs will behave in their intended environments without having to
build and test multiple physical prototypes. Engineers use our simulation software to construct computer models of products, components, systems and assemblies and to simulate performance conditions and predict physical responses to certain
variables, such as stress, motion and temperature. These capabilities allow our customers to optimize product designs, improve product quality and reliability, comply with regulatory and safety guidelines, reduce product development costs and
shorten the timeline in bringing new products to market. We also provide a broad range of strategic consulting services to help our customers implement enterprise simulation solutions and improve the integration and performance of their product
development process, which will lower the total cost of ownership of their technology investments. We serve customers in various industries, including aerospace, automotive, defense, heavy machinery, electronics, consumer products, biomedical,
shipbuilding and rail. Advances in computer technology have made virtual product development solutions available for any and all companies that manufacture products.

Our goal is to provide our customers with leading edge enterprise simulation solutions that will integrate design and engineering processes to enable innovative product design and efficient product development. We
seek to be an industry leader in each of the product categories in which we compete and to expand into new and emerging markets within the product lifecycle management (PLM) industry.

Industry

The PLM industry includes four significant
segments: conception of the product, design of the product, manufacture of the product, and maintenance of the product. These product lifecycle segments utilize various digital technologies and software tools, often referred to as PLM tools,
including mechanical computer-aided design (CAD), computer-aided engineering (CAE), computer-aided manufacturing (CAM), and product data management (PDM) and related services.

Enterprise simulation solutions enable engineers to prototype, simulate, test and iterate scenarios in a virtual environment. This enterprise simulation
environment allows engineers to migrate to design-analyze-confirm processes, which creates a more flexible, efficient and cost-effective solution for product development. As a result, companies obtain a competitive advantage through
innovation, manufacturing efficiency, speed to market, and lower development costs.

Enterprise simulation solutions, including our
software and services, are used in conjunction with these PLM tools throughout the entire product lifecycle. Enterprise simulation solutions integrate multi-disciplinary CAE simulation software technologies with the enterprise during all phases of
the product development process. As a result, designers, analysts, program managers and others on the product development team gain greater, more accurate, and more timely insight into product behavior, thus providing a strategic element in
achieving business objectives. Before the development of enterprise

simulation software, product design and simulation was often disjointed, unrepeatable, and error prone requiring intensive manual redesign prior to and
during manufacturing. With a lack of multi-discipline simulation during product development, engineers were involved in design-build-test-break processes which limited the number of cycles such processes could be repeated due to time and
cost limitations.

According to an industry report from Daratech, Inc. CAE software and services topped $2.4 billion in 2006, a
year-over-year increase of 8%. Daratech, Inc. projects that CAE software and services spending is expected to grow 9% and reach nearly $2.7 billion in 2007, while spending on PLM software and services totaled nearly $11.4 billion in 2006, a
year-over-year increase of 8%.

Our Competitive Strengths and Growth Strategy

We currently support four product categories of simulation technologies through a portfolio of simulation software products and solutions. We consider our
portfolio of simulation software to be one of the broadest and most widely used within the CAE segment of the engineering software market. We believe our simulation software is the de-facto standard within the aerospace and automotive industries,
capable of being utilized on various computer platforms ranging from large mainframes to basic laptops.

We believe our newly introduced
SimEnterprise and multi-discipline (MD) products will transform the industry from offering point simulation tools to one providing enterprise integrated simulation solutions, thereby giving our customers a complete enterprise integrated
suite of simulation software. Such transformation will enable designers, analysts, managers and the supply chain to integrate simulation throughout the design process in an open systems framework. With thousands of global accounts among diverse
industries, including aerospace, automotive, machinery, electronics, equipment and consumer products, we believe we have a unique competitive advantage in leveraging new product releases and related professional services to existing and new
customers and in penetrating new markets.

We intend to maintain this competitive advantage by providing superior technology and functional
breadth of simulation solutions and collaborating with customers to deliver the next generation of enterprise simulation software and solutions. We will continue to evaluate our business model, including our product mix and positioning, marketing
strategies and sales channels to maximize our market opportunities and to improve our operating results. We are committed to improving our cost structures and will continue to streamline our business operations as necessary to successfully compete
in all our geographic locations.

Our goal for growth is to expand our leading position in the simulation software market by further
penetrating our installed base, by adding new customers from the supply chains in our existing aerospace and automotive markets, and by expanding with new customers in new markets such as biomedical and consumer products.

Software Products

Our simulation software products
consist of physics-based solvers, accessible through graphical user interfaces sometimes referred to as pre- and post-processors, which are enterprise enabled thus supporting the management of the simulation across the various enterprise users. The
governing principle for our enterprise software is to provide an integrated suite of simulation software applications to enhance engineering productivity for product design teams at large global manufacturers as well as at small and medium
manufacturers.

We market our enterprise simulation software products under four main product categories:

Engineering ProductsThis category includes software to model and simulate the performance characteristics of a wide variety of complex
mechanical conditions. Within this category we include our core engineering simulation software, including MSC Nastran, Patran, Adams, Marc, Dytran, Easy5 and SOFY.

MD SolutionsThis category, introduced in 2006, is designed for manufacturers who need to perform interoperable, multi-disciplinary analyses on ever-more complex products and assemblies. Within this
category we include our MD Nastran, MD Patran, and MD Adams products.

customers current simulation processes, comparing them to industry best practices and indicating areas for improvement. As a result of these assessments we design new enhanced processes and implement them within the customers product
development process.

With engineering consulting engagements, we provide engineering simulation to our existing software customers and to
companies who do not use our software. These services are delivered to our current customers to provide simulation or design expertise that they may not have and to augment their capabilities if they have a personnel shortage. These services are
also provided to companies who do not have any simulation or design professionals on staff but who need these capabilities provided via outsourcing. We have provided services to automotive, aerospace, biomedical, electronic packaging, petrochemical,
nuclear and consumer product manufacturers and suppliers.

Our training and onsite support services help our customers get the most out of
their MSC Software enterprise solution. We have developed educational tools designed to train users of our products as an extension of our software business. Training seminars are conducted in local languages on a frequent basis at our offices
worldwide, and at client sites. We also provide personnel dedicated to onsite support for our software.

Research and Development

We dedicate significant resources to the development and enhancement of our simulation software products as well as to new product research and development. Our development activities have historically involved
developing new products to address new simulation market opportunities, adding new capabilities to our suite of simulation software, or converting those programs for use on new computer platforms. These activities are intended to drive and maintain
market leadership as well as to prevent technological obsolescence. In 2004, 2005 and 2006, our research and development expenditures totaled $42.1 million, $47.3 million and $43.2 million, respectively. In 2007, we expect to spend approximately $49
million in research and development.

Sales and Marketing

We market and sell our products and services in North America and Latin America (the Americas), Europe, the Middle East and Africa (EMEA), and Asia Pacific through a dedicated sales force, as
well as through third parties, including agents and value added resellers. In 2004, 2005 and 2006, our foreign operations generated approximately 66.6%, 70.4% and 70.8%, respectively, of our total revenue.

We also market our products by advertising in trade publications, participating in industry trade shows, conferences and exhibits, conducting training
seminars and working with our strategic partners.

Historically, our software products were used primarily by the simulation experts
supporting the design phase of product development. Accordingly, we targeted our marketing efforts on the product design engineers and analysts. With the addition of our MD and Enterprise solutions, we expanded our marketing efforts to target the
senior management of engineering and IT departments. We now have a value proposition that drives the entire enterprise lifecycle of a product.

Pricing

In general, we provide two types of licensing alternatives for the use of our software products - an annual non-cancelable lease
license and a perpetual (paid-up) license. We also offer MSC MasterKey, a token-based model, enabling customers to access our engineering products from a single, flexible license; and Enterprise Advantage, a license unit model enabling customers to
access our MD and Enterprise solutions software from a scalable enterprise license. MasterKey tokens and Enterprise Advantage license units are offered on a paid-up basis. With both annual and paid-up software licenses, the license fee is set at a
fixed rate and the customer is invoiced at the time of sale. Software licenses are generally sold with maintenance, which entitles the customer to receive unspecified upgrades, enhancements and support. Maintenance fees typically approximate 20% of
software license fees, and maintenance agreements are generally for one year.

Pricing of products licensed in Europe through our European
subsidiaries are generally denominated in Euros or other local currencies. Products licensed in Asia Pacific through our Asia Pacific subsidiaries are generally denominated in Japanese Yen or other local currencies.

Post Sales Support

Client service is an integral
aspect of our marketing program. We maintain both on-line web support and toll-free phone numbers as a hot line service for our clients. We conduct formal training for clients, ranging from three-day introductory courses to intensive courses on
specialized subjects for experienced users. Onsite courses for clients are provided for larger user organizations. We also host technology conferences in the United States, Europe, Asia Pacific, Australia and Latin America to gather data on client
needs, new engineering applications, and new trends in computing technology.

Sales and Support Offices

We have sales and client support offices at our worldwide headquarters in Santa Ana, California, and in over 55 other locations throughout the Americas,
EMEA and Asia Pacific. Our products are marketed, distributed and supported outside of North America through a network of foreign subsidiary offices, including a European subsidiary headquartered in Munich, Germany, and an Asia Pacific subsidiary
headquartered in Tokyo, Japan. Product support and training are also available in many of our locations.

Customers

Our customer base consists of thousands of companies and is diversified across industry sectors and geographies. Our customers include industry leaders in
automotive, aerospace, defense and heavy machinery. No single customer accounted for more than 10% of our revenue in 2004, 2005, or 2006.

##### Table of Contents

We have long-standing relationships with many of our customers, and the average tenure of our
top 10 customers is more than 20 years. Our major end-user customers, based upon 2006 revenue, include: Boeing, Airbus, BAE, Lockheed Martin, Nissan Motor (NML), Toyota, Northrop Grumman and Honda.

Backlog

We generally ship our software products
within 30 days after acceptance of an order and execution of a software license agreement. Accordingly, we do not believe that our backlog of software arrangements at any particular point in time is indicative of future sales. Backlog for our
consulting services is currently not material.

Intellectual Property Rights

We regard our software as proprietary and rely on a combination of trade secret, copyright and trademark laws, license agreements, nondisclosure and other
contractual provisions and technical measures to protect our proprietary rights in our products. We distribute our software products under software license agreements that grant customers nonexclusive licenses for the use of our products, which are
generally nontransferable. Use of the licensed software is restricted to designated computers at specified sites, unless the customer obtains a license offering other access to the software. Software and hardware security measures are also employed
to prevent unauthorized use of our software, and the licensed software is subject to terms and conditions prohibiting unauthorized reproduction and export of the software.

MSC, MSC/, Adams, Patran, Mvision, Dytran, Marc, Mentat and Easy5 are some of our registered trademarks. NASTRAN is a registered trademark of NASA. MSC
Nastran is an enhanced proprietary version of NASTRAN. Many of our trademarks have also been registered in foreign countries.

In addition,
we maintain federal statutory copyright protection with respect to our software programs and products and have copyrights on documentation and manuals related to these programs.

Competition

The CAD, CAE, and broader PLM markets are intensely competitive and characterized by
rapidly changing technology and evolving standards. We expect competition to increase both from existing competitors and new market entrants. We believe that the principal competitive factors affecting the software business include ability to solve
customer problems, quality, functionality, performance, ease of use and, to a lesser extent, price. In our services business, we believe that the principal competitive factor is expertise.

With respect to our software business, the Companys primary competitors include:



| |  |  | Altair Engineering, Inc.
| | - |  | ------------------------



| |  |  | ANSYS, Inc.
| | - |  | -----------



| |  |  | Dassault Systemes
| | - |  | -----------------



| |  |  | LMS International
| | - |  | -----------------

In our services
business, we compete with in-house information technology personnel and consulting groups.

Although we believe we currently compete
effectively with respect to these factors, we may not be able to maintain our competitive position against current and potential competitors, who may have greater financial, technical, marketing and other resources than we do. It is also possible
that partnerships among competitors may emerge and acquire market share or that competition will increase as a result of industry consolidation. Increased competition could result in price reductions, reduced profitability and loss of market share,
any of which could materially adversely affect our business, operating results or financial conditions.

Employees

As of December 31, 2006, we employed 1,234 persons, of whom 590 were involved in sales, marketing and field support, 396 in technical activities, and
248 in administration. None of our U.S. employees are represented by a labor union. Certain foreign jurisdictions have workers councils that typically represent workers on matters generally affecting terms of employment. We have never experienced
any work stoppages and believe our relations with employees are good. Reliance upon employees in other countries may increase risks associated with government instability or regulation unfavorable to foreign-owned companies that could
negatively impact our operations in the future.

Recruiting and retaining highly skilled employees, especially software developers and engineers, is
highly competitive. We believe our growth and future success is dependent on our ability to attract, retain and motivate highly skilled employees.

In January 2007, we announced a cost reduction program, which included a 7% reduction of our workforce, to better align our operations and costs in support of the transition to MD, Enterprise and Channel products. We believe the cost
reduction program will enhance our ability to compete aggressively in all markets and to improve operating profit.

|ITEM 1A. | RISK FACTORS
|-------- | ------------

Downturns in the aerospace and automotive
industries we serve would adversely affect our sales and operating results.

In 2006, sales to customers in the aerospace and automotive
industries accounted for a majority of our revenue. Reductions in capital spending and cyclical trends affecting customers in these industries could adversely affect revenue from these customers and our results of operations. In addition, these
types of customers tend to adhere to a technology choice for long periods, possibly an entire development cycle. As a result, a lost opportunity with a given customer may not again become a new opportunity for several years.

If we do not acquire other companies, we may not be able to increase our revenue at historical growth rates.

Our historical revenue growth has been augmented by acquisitions. Our future revenue growth rate may decline if we do not make acquisitions of similar
size and at a comparable rate as in the past.

We have acquired and may continue to acquire other companies and may be unable to integrate successfully
such companies with our operations, and we have recorded, and may continue to record, a significant amount of goodwill in connection with our acquisitions.

Since 1998, we have acquired several companies and businesses, most recently SOFY in 2004. We may continue to expand and diversify our operations with additional acquisitions. Some of the risks that may affect our
ability to integrate or realize any anticipated benefits from companies we acquire include those associated with:



| |  |  | integrating the operations, technologies, products and personnel;
| | - |  | -----------------------------------------------------------------



| |  |  | unexpected losses of key employees or customers of the acquired company;
| | - |  | ------------------------------------------------------------------------



| |  |  | conforming the acquired companys standards, processes, procedures and controls with our operations;
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | coordinating our new product and process development;
| | - |  | -----------------------------------------------------



| |  |  | hiring additional management and other critical personnel;
| | - |  | ----------------------------------------------------------



| |  |  | increasing the scope, geographic diversity and complexity of our operations;
| | - |  | ----------------------------------------------------------------------------



| |  |  | difficulties in consolidating facilities and transferring processes and know-how;
| | - |  | ---------------------------------------------------------------------------------



| |  |  | other difficulties in the assimilation of acquired operations, technologies or products; and
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | adverse effects on existing business relationships with customers.
| | - |  | ------------------------------------------------------------------

If we are unsuccessful in integrating these companies or product lines with our operations, or if integration is more difficult than anticipated, we may experience disruptions that could have a material adverse effect
on our business, financial condition and results of operations. As a result of our acquisitions, goodwill accounted for approximately $151.7 million, or 33.0%, of our total assets, as of December 31, 2006. We may record additional goodwill
related to future acquisitions. Under current generally accepted accounting principles, we do not amortize goodwill. We will, however, perform an impairment analysis on the carrying value of our goodwill at least annually. If the financial benefits
of our acquisitions do not ultimately exceed the associated costs, we could be required to write down some or all of the unamortized goodwill. As a result, our results of operations would be adversely affected.

Mergers and acquisitions and investments in technology companies are inherently risky, and no assurance can be given that our previous or future
acquisitions or investments will be successful and will not materially adversely affect our business, operating results, or financial condition. Failure to manage and successfully integrate acquisitions could materially harm our business and
operating results. Even when an acquired company has already developed and marketed products, there can be no assurance that product enhancements will be made in a timely fashion or that pre-acquisition due diligence will have identified all
possible issues that might arise with respect to products or the acquirees business. If we are unable to complete an acquisition or an acquisition is delayed, our business could be adversely affected due to diversion of management attention
and company resources from alternative approaches, which may prevent us from achieving strategic goals.

We may also incur third party
costs in the evaluation, negotiation and completion of acquisitions. These costs are deferred and treated as part of the acquisition cost upon completion of the acquisition. If an acquisition is not completed, the deferred costs are charged to
earnings in the period in which the acquisition is certain not to be completed, which can impact our results of operations.

##### Table of Contents

We have had losses and, should they recur, it could have a material adverse effect on our business, results of
operations and financial condition.

Our net income for the years ended December 31, 2004, 2005, and 2006 was $10.9 million, $11.8
million and $13.8 million, respectively, and we had an accumulated deficit of $97.0 million as of December 31, 2006. We cannot assure you that we will operate profitably, and if we cannot operate profitably, we may not be able to meet our debt
service requirements or our working capital or other needs. Our inability to meet these needs could have a material adverse effect on our business, results of operations and financial condition.

We may periodically restructure our operations or change our pricing model, which could adversely impact our operating results in the short term before we receive any
benefits from these changes, if at all.

We continually evaluate the strengths and weaknesses of our operations. In connection with
this evaluation, we may decide to reduce or realign our available resources and, as a result, consolidate, shut down or sell product lines that do not fit into our long-term business plan. If we reduce headcount in the future, we will incur
significant severance and termination costs and other related expenses that could harm our business before we were to receive any benefit, if at all, from the reduced headcount expenses. If we shut down or otherwise dispose of any of our
product lines in the future, we may incur costs or charges, receive less in the sale than such assets are worth, disrupt customer goodwill or lose revenue streams in connection with such a restructuring that could harm our business before we were to
receive any benefit, if at all, from the restructuring. In addition, we may introduce changes to our pricing model, and these changes may not result in increased or even the same level of revenue in the timeframes that we anticipate, or at all.

On January 17, 2007, our Board of Directors approved the implementation of a cost reduction program that included a workforce
reduction of 85 employees, or approximately 7%, and facility closings and consolidations. The cost reduction program was deemed necessary to better align the Companys global operating costs with its new enterprise sales strategy in an effort
to compete aggressively in all markets and to improve operating profit. The Company estimates that total costs related to the cost reduction program will be between $6.0 million and $8.0 million, which includes a charge for severance and termination
benefits of between $5.0 million and $6.5 million and charges related to facility closings and consolidations of between $1.0 million and $1.5 million. The Company expects such charges will be incurred and recognized in the first and second
quarters of 2007.

Our operating results are dependent in part on our ability to develop and introduce new and enhanced products and we may not be able
to develop new and enhanced products to satisfy changes in demand.

Our operating results depend in part on our ability to develop and
market new and enhanced products on a timely basis. Successful product development and marketing depends on numerous factors, including our ability to anticipate customer requirements, changes in technology, our ability to differentiate our products
from those of our competitors, and market acceptance. We may not be able to develop and market new or enhanced products in a timely or cost-effective manner or to develop and introduce products that satisfy customer requirements. Our products also
may not achieve market acceptance or correctly anticipate technological changes.

Our sales cycle is lengthy and complicated.

The development of a business relationship with a potential licensee can be a lengthy process, spanning twelve months or longer, especially for large
enterprise transactions. The Companys strategy is to increasingly allocate sales resources towards large enterprise transactions. The sales cycle can involve multiple divisions within a potential licensees organization and multiple
layers of management, thus making our sales process relatively complicated and long. Additionally, negotiating the terms of a new license agreement can be a protracted process with no set timetable for completion. Due to the length and complicated
nature of our sales cycle, predicting the fiscal period in which a new license agreement will be entered into, if at all, and the financial terms of such an agreement is difficult.

The timing of orders and shipments, which frequently occur at the end of a quarter, can cause fluctuations of our operating results that, in turn, may impact the price of our common stock.

We derive most of our revenue from licensing software products and selling services to high-end users of the product design markets. Our revenue growth
and our ability to match spending levels with revenue growth rates will directly affect our future operating results. Historically, a significant portion of our revenue has been generated in the last month of a quarter, with this revenue frequently
concentrated in the last weeks or days of a quarter. In addition, higher volumes of orders have been experienced in the fourth quarter. The concentration of orders makes projections of quarterly financial results difficult. Accordingly, we may
experience fluctuations in our future operating results on a quarterly and annual basis which, in turn, could adversely affect the price of our common stock.

Our future results could be harmed by economic, political, regulatory and other risks associated with international
sales and operations.

Although we may not be successful in expanding into particular international markets, or generating revenue from
foreign operations, we currently anticipate that revenue from international operations will continue to represent a substantial portion of our total revenue. Expansion into international markets requires management attention and resources. We may
not be successful in expanding into particular international markets or in generating revenue from foreign operations. Accordingly, our future results could be harmed by a variety of factors related to our international operations, including:



| |  |  | changes in foreign currency exchange rates;
| | - |  | -------------------------------------------



| |  |  | changes in a specific countrys or regions political or economic conditions, particularly in emerging markets;
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | burdens on complying with a wide variety of foreign laws and regulations;
| | - |  | -------------------------------------------------------------------------



| |  |  | meeting import and export licensing requirements;
| | - |  | -------------------------------------------------



| |  |  | natural disasters or outbreaks of infectious diseases affecting the regions in which we or our licenses sell products;
| | - |  | ----------------------------------------------------------------------------------------------------------------------



| |  |  | tariffs, trade protection measures and import or export licensing requirements;
| | - |  | -------------------------------------------------------------------------------



| |  |  | potentially negative consequences from changes in foreign government regulations, tax laws and regulatory requirements;
| | - |  | -----------------------------------------------------------------------------------------------------------------------



| |  |  | difficulty in managing a geographically dispersed workforce in compliance with diverse local laws and customs;
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | disproportionate management attention or company resources;
| | - |  | -----------------------------------------------------------



| |  |  | changes in diplomatic and trade relationships;
| | - |  | ----------------------------------------------



| |  |  | longer accounts receivable payment cycles; and
| | - |  | ----------------------------------------------



| |  |  | less effective protection of intellectual property.
| | - |  | ---------------------------------------------------

We are subject to changes in demand for our products and services resulting from exchange rate fluctuations that make our products and services relatively more or less expensive in international markets. If exchange
rate fluctuations occur, our business could be harmed by decreases in demand for our products and services or reductions in gross margins.

We have
entered into agreements with third parties for the inclusion of their technology as a component of some of our products. The termination of these agreements could adversely affect our business.

Some of our products include technology licensed from third parties and we have entered into several royalty agreements for use of such technology.
Should these agreements be terminated, we would need to find an alternative source to replace the functionality of such technology. We believe that we would be able to find an alternative source of the technology, or replace the functionality
through internal development. In addition, these agreements allow for significant lead time prior to termination by the third party, which should allow us sufficient time to replace the functionality. However, in the event that all of these
agreements were terminated within a very short time period, there is no guarantee that we could replace the technology and the marketability of our products could be harmed if we were unable to do so. In addition, certain products or technologies
acquired or developed by us may incorporate so-called open-source software. Open source software is typically licensed for use at no initial charge, but certain open source software licenses impose on the licensee of the applicable open
source software certain requirements to license or make available to others both the open source software as well as the software that relates to, or interacts with, the open source software. Our ability to commercialize products or technologies
incorporating open source software or otherwise fully realize the anticipated benefits of any such acquisition may be restricted as a result of using such open source software because, among other reasons:



| |  |  | open source license terms may be ambiguous and may be subject to unanticipated obligations regarding our products and technologies;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------



| |  |  | competitors may have improved access to information that may help them develop competitive products:
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | open source software cannot be protected under trade secret law;
| | - |  | ----------------------------------------------------------------



| |  |  | it may be difficult for us to accurately determine the origin of the open source code and whether the acquired open source software in fact infringes third party
intellectual property rights; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | open source software potentially increases customer support cost because (i) such software typically does not contain warranties as to functionality or is not
accompanied by any support offerings from the provider of such open source software and (ii) licensees can modify the software and potentially introduce errors.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

In addition, the operation of our software will be impaired if errors occur in third-party software that
we utilize. It may be more difficult for us to correct any defects in third-party software because the development and maintenance of the software is not in our control. Accordingly, our business could be adversely affected in the event of any
errors in our software. There can be no assurance that these third-parties will continue to make their software available to us on acceptable terms, will continue to invest the appropriate level of resources in their products and services to
maintain and enhance the software capabilities, or will continue to remain in business.

Our operating expenses are fixed in advance. Therefore, we have
limited ability to reduce expenses in response to any revenue shortfalls.

We plan our operating expense levels, in part, on expected
revenue growth. Our expense levels, however, are generally committed in advance and, in the near term, we are able to change only a relatively small portion of our expenses. As a result, our ability to convert operating outlays into expected revenue
growth at profitable margins will affect our future operating results. If our future revenue is less than expected, our net income may be disproportionately affected since expenses are relatively fixed.

Strong competition in the simulation software industry may affect prices, which could reduce margins and adversely affect our operating results and financial
position, and we may not be able to maintain our competitive position against current and potential competitors.

The simulation
software industry is highly competitive. The industry may experience pricing and margin pressure which could adversely affect our operating results and financial position. Some of our current and possible future competitors have greater financial,
technical, marketing and other resources than we do, and some have well-established relationships with our current and potential customers. It is also possible that alliances among competitors may emerge and rapidly acquire significant market share
or that competition will increase as a result of software industry consolidation. To remain competitive, we must continue to invest significant resources in research and development, sales and marketing and customer support. Increased competition
may result in price reductions, reduced profitability and loss of market share, any of which could have a material adverse effect on our business, financial condition and results of operations. We believe that the principal competitive factors
affecting the software business include quality, functionality, ease of use and, to a lesser extent, price. In our professional services business, we believe that the principal competitive factor is expertise. We cannot assure you that we will be
able to maintain our competitive position against current and potential competitors.

Our future success depends in part on the continued service of our
key technical and management personnel and our ability to identify, hire and retain additional personnel.

There is intense competition
for qualified personnel in the software industry. We may not be able to continue to attract and retain qualified personnel necessary for the development of our business or to replace qualified personnel who may leave our employ in the future. Any
growth we experience is expected to place increased demands on our resources and will likely require the addition of management and technical personnel, and the development of additional expertise by existing management personnel. Loss of the
services of, or failure to recruit, key technical and management personnel could harm our business.

Business interruptions could adversely affect our
business.

Our operations and those of our licensees, developers and customers are vulnerable to interruptions by fire, flood,
earthquake, power loss, telecommunications failure, terrorist attacks, wars and other events beyond our control. Our corporate headquarters are located in California, near major earthquake faults. A catastrophic event that results in the destruction
of any of our critical business or information technology systems could severely affect our ability to conduct normal business operations and as a result, our future operating results could be adversely affected. The business interruption insurance
under which we are covered may not be sufficient to compensate us fully for losses or damages that may occur as a result of these events, if at all. Any such losses or damages incurred by us could have a material adverse effect on our business.

If we cannot adequately protect our intellectual property rights, our financial results may suffer.

Our ability to compete is affected by our ability to protect our intellectual property rights. We rely on a combination of trademarks, copyrights, trade
secrets, confidentiality procedures and non-disclosure and licensing arrangements to protect our intellectual property rights. Despite these efforts, the steps we take to protect our proprietary information may not be adequate to prevent
misappropriation of our technology, and our competitors may independently develop technology that is substantially similar or superior to our technology.

We may be required to spend significant resources to monitor and police our intellectual property rights.
Policing the unauthorized use of our products or intellectual property is difficult and litigation may be necessary in the future to enforce our intellectual property rights. Regardless of the merits of any claim, intellectual property litigation is
expensive and time-consuming and could divert our managements attention from operating our business. Despite our efforts, we may not be successful in any litigation or other enforcement action we may bring and may not be able to detect
infringement and, as a result, may lose competitive position in the market. In addition, competitors may design around our technology or develop competing technologies. Intellectual property rights may also be unavailable or limited in some foreign
countries, which could make it easier for competitors to capture market share.

Despite our efforts to protect our proprietary rights,
existing laws, contractual provisions and remedies afford only limited protection. Intellectual property lawsuits are subject to inherent uncertainties due to the complexity of the technical issues involved, among other things, and we cannot assure
you that we will be successful in enforcement of, or defending ourselves against, intellectual property claims. Moreover, attempts may be made to copy or reverse engineer aspects of our product or to obtain and use information that we regard as
proprietary. Accordingly, we cannot assure you that we will be able to protect our proprietary rights against unauthorized third-party copying or use. Unauthorized use by others of our proprietary rights could materially harm our business.

We could be harmed by litigation involving intellectual property rights.

We may be accused of infringing the intellectual property rights of third parties. Furthermore, we may have certain indemnification obligations to
customers with respect to the infringement of third-party intellectual property rights by our products. Infringement claims by third parties or claims for indemnification by customers or end users of our products resulting from infringement claims
may be asserted in the future and such assertions, if proven to be true, may harm our business. Any litigation relating to the intellectual property rights of third parties, whether or not determined in our favor or settled by us, would at a minimum
be costly and could divert the efforts and attention of our management and technical personnel. In the event of any adverse ruling in any such litigation, we could be required to pay substantial damages, cease the manufacturing, use and sale of
infringing products, discontinue the use of certain processes or obtain a license under the intellectual property rights of the third party claiming infringement. A license might not be available on reasonable terms, or at all.

Certain provisions of our certificate of incorporation may delay, defer or prevent a change in control which could impact the price of our stock.

Certain provisions of our Certificate of Incorporation, as amended, and Restated Bylaws could make it more difficult for a third party to acquire control
of us, even if the change in control would be beneficial to stockholders. These provisions include the following:



| |  |  | division of our board of directors into three classes, with each class serving a staggered three-year term;
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | removal of directors for cause only;
| | - |  | ------------------------------------



| |  |  | ability of the board to authorize the issuance of preferred stock in series;
| | - |  | ----------------------------------------------------------------------------



| |  |  | vesting of authority in the board to determine the size of the board (subject to certain limited exceptions) and to fill vacancies thereon; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | advance notice requirements for stockholder proposals and nominations for election to the board.
| | - |  | ------------------------------------------------------------------------------------------------

In addition to the above provisions, in 1998 we adopted a shareholder rights plan. This plan was amended as of October 18, 2004 and entitles each
registered holder to purchase from us, under certain circumstances, one one-hundredth of a share of Junior Participating Preferred Stock at a price of $35.00, subject to adjustments. The rights are generally exercisable only if a person or group
acquires 20.0% or more of our stock or announces a tender or exchange offer the completion of which would result in ownership by a person or group of 20.0% or more of our stock. In the event of a transaction commonly known as a squeeze-out
merger, each holder of Junior Participating Preferred Stock may purchase either our common stock or the common stock of the merged entity at one-half of such stocks market value. We may redeem the rights at a nominal value until ten days
after the announcement of the acquisition of such a 20.0% interest and under certain other circumstances.

|ITEM 2. | PROPERTIES
|------- | ----------

All of our offices are leased under
agreements expiring at various times over the next one to 10 years. Our corporate headquarters in Santa Ana, California includes 203,511 square feet under a lease expiring in 2013, of which approximately 92,000 square feet is sublet. We also
lease approximately 374,000 square feet in 56 other offices throughout the world for sales, support, research and development, consulting and administrative personnel. All facilities are in good condition and are adequate to meet our requirements
for the foreseeable future. See Note 12Commitments and Contingencies in Notes to Consolidated Financial Statements for additional information regarding our lease obligations.

In January 2007, as part of a company-wide restructuring plan, we announced our commitment to close or consolidate certain facilities that may eliminate
up to 85,000 square feet of leased space from our operations.



|ITEM 3. | LEGAL PROCEEDINGS
|------- | -----------------

We are subject to various claims
and legal proceedings that arise in the ordinary course of our business, including claims and legal proceedings that have been asserted against us by former employees. The Company is vigorously defending these claims, and believes that it has
adequately reserved for potential costs to the Company resulting from these matters. No assurance can be given, however, that the ultimate outcome of these claims will not have a material adverse effect on the Companys financial condition or
results of operations.

On August 10, 2006, we settled an action by a former senior vice president alleging both employment-related
claims as well as claims for breach of his stock option agreement. The amount of the settlement paid in August 2006 was accrued as of June 30, 2006.

The Company is periodically audited by various taxing authorities in the United States of America and in other countries in which the Company does business. In the opinion of management, these matters will not have a
material adverse effect on the Companys consolidated balance sheet, statements of operations or liquidity.

On November 16,
2006, the SEC notified us that it has terminated its investigation that has been underway since April 2005 in connection with matters related to the restatement of financial statements for periods subsequent to December 31, 2001. No enforcement
action was recommended as a result of this investigation.

ISSUER PURCHASES OF EQUITY SECURITIES

On September 5, 2006, the Companys common stock began trading on NASDAQ
under the symbol MSCS. From March 11, 2005 through September 4, 2006, our stock was traded on the Pink Sheets electronic quotation system under the ticker symbol MNSC after the New York Stock Exchange (the
NYSE) informed us that, because of the ongoing delay in the filing of our 2003 Annual Report on Form 10-K with the SEC, the NYSE would suspend trading in our stock on the NYSE before the opening of the market on March 11, 2005.
Prior to that, our common stock was listed for trading on the NYSE under the symbol MNS. The following table sets forth the high, low and closing prices, as reported on the respective trading systems, for the periods shown:

##### Table of Contents

As of December 31, 2006, there were 207 record holders of our common stock. Because many of our
shares are held by brokers or other institutions on behalf of stockholders, we are unable to estimate the total number of stockholders represented by the record holders.

We eliminated our dividend in September 1996 and do not anticipate paying a dividend in the foreseeable future.

We maintain the MSC.Software Profit Sharing Plan which includes a 401(k) feature that allows participants to make contributions to the plan from their compensation on a before-tax basis. A participants
contributions to the plan are credited to an account maintained in his or her name under the plan. Through March 2005, a participant was permitted to invest his or her Profit Sharing Plan account in the MSC Stock Fund, an investment alternative
under the plan that was invested principally in our common stock. Shares held in the MSC Stock Fund under the Profit Sharing Plan were purchased by the plan trustee on the open market using contributions invested in that fund. This practice was
suspended in March 2005 after our common stock was delisted from the NYSE. As of December 31, 2005 and 2006, the number of shares of our common stock held in the MSC Stock Fund totaled 94,638 and 81,729, respectively.

Common Stock Repurchase Program

On November 8, 2006, the Board of Directors authorized a stock repurchase program for up to 1,250,000 shares of common stock. Share repurchases will be made from time to time in the open market, based on stock availability and price.
It is anticipated that the repurchases will be made during the next twelve months, although no assurance can be given as to when they will be made or the total number that will be repurchased. The stock repurchase program has no stated expiration
date. Through December 31, 2006, the Company purchased an aggregate of 183,400 shares for $2,581,000. Payments made for repurchased stock are recorded in treasury stock in the accompanying consolidated balance sheet.

The table below sets forth information regarding repurchases of MSCs common stock by the Company during the quarter ended December 31, 2006.

|ITEM 7. | MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
|------- | -------------------------------------------------------------------------------------

Forward-Looking Statements and Factors That May Affect Future Results

This discussion
contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those discussed below. Factors that could cause or contribute to such differences include, but are not limited to, those
identified below, and those discussed in the section titled Item 1A. Risk Factors included elsewhere in this report. You should also carefully review the risk factors set forth in other reports or documents that we file from time to time
with the Securities and Exchange Commission, particularly Quarterly Reports on Form 10-Q and any Current Reports on Form 8-K. You should also read the following discussion and analysis in conjunction with our consolidated financial
statements and related notes included in this report.

Overview

We manage our business under two operating segmentssoftware and services. Our revenue is derived through our direct sales force, a network of value-added resellers and other sales agents. Revenue generated by
our software segment consists of licensing fees that are earned through time-based lease arrangements and paid-up (perpetual) license arrangements, whereby the customer purchases a license for the use of our software. Both lease and paid-up
arrangements are typically sold with maintenance for a period of time. Revenue generated by our services segment consists of maintenance and services revenue. Maintenance revenue includes unspecified software upgrades, enhancements and technical
post-contract support (together known as E&S). Services revenue includes consulting and training services, including services provided in connection with software installation.

We operate our business in three geographic regions: The Americas (North America and Latin America), EMEA (Europe, Middle East and Africa), and Asia
Pacific (Japan, Korea, The Peoples Republic of China, Taiwan, Southeast Asia and India), and manage all of our operations based on software sold and services provided to our customers. These regions operate similarly with respect to
industries, customer base and sales channels, but each has unique challenges and opportunities. Although our consolidated results are reported in United States currency, our foreign regions conduct a significant number of transactions in local
currency. As a result, our consolidated results of operations may be significantly impacted by changes in foreign currency exchange rates.

The following table shows the changes in the reporting currencies of our EMEA and Asia Pacific regions from which we derive a significant portion of our revenue:

Business Environment

Significant portions of our current and past revenue sources are attributable to our long-term relationships with major OEMs and their key suppliers, who have embedded our software solutions within their
collaborative design and manufacturing processes. Such embedding of our software provides new and recurring revenue opportunities with respect to the development and marketing of new products, renewal of maintenance contracts, and consulting
services. Our customers typically fund purchases of our software and services largely out of their manufacturing and capital budgets and, to a lesser extent, their research and development (R&D) budgets. As a result, our
customers business outlook and willingness to invest in new product development significantly affect the growth of our business.

Our
customers, many of which have global operations, continue to reevaluate their business models to obtain competitive advantages through product innovation, manufacturing efficiency, speed to market and lower cost. This focus has often resulted in
massive shifts of production and manufacturing capabilities to lower cost regions of the world, including developing countries. We believe this migration has helped our current and prospective customers to compete globally and will increase demand
for their products in new markets. This phenomenon in turn creates both opportunities and challenges in the regions we operate. As our current customers expand or contract their operations and supporting supply chains, we are directly affected. In
addition, the growth in developing countries within the regions we operate, namely Central and Eastern Europe, China, India and Korea, have allowed some companies who traditionally provided contracted services to expand into product development.
This also will create new opportunities within new markets for us to pursue.

During times of economic uncertainty, companies will place greater emphasis on creating the most cost
effective and competitive business model, including expense reductions within their capital and R&D budgets. Some customers may reduce their PLM expenditures by decreasing their level of software purchases, use older generations of products or
not renew maintenance services. In addition, customers will bargain more intensely on pricing and payment terms, which will affect PLM related revenues industry-wide. Lastly, some customers may consolidate their PLM purchases with fewer suppliers in
order to lower their overall cost of ownership while at the same time meeting new technology challenges. This will increase competition among PLM vendors.

Recognizing that companies will continue to justify their PLM spending and will work to aggressively contain costs, we are dedicated in improving our customers product development and manufacturing capabilities
by providing more fully integrated simulation software within an enterprise solutions environment and offering customers a wide range of software products and solutions. Over the long term, we believe PLM spending growth will continue to depend on
growth in product development and engineering spending and on continued growth in key markets and industries we serve.

According to
Daratech, Inc., approximately 21% of PLM investments came from CAE in 2006 and over the next four years, CAE is expected to match the overall PLM growth rate, which is expected to rise to 10% annual growth in 2010 with a total market exceeding $16
billion. However, we cannot currently predict whether this outlook will contribute to higher simulation software spending.

Product Development and
Revenue Growth

Our goal for growing market share and profitability is to expand our leading position in the simulation software market
by further penetrating our installed base, by adding new customers from the supply chains in our existing aerospace, automotive and heavy manufacturing markets, and by targeting new markets such as biomedical and consumer products.

During 2006, we announced or introduced a number of new enterprise simulation solutions, including:



| |  |  | MD SolutionsDesigned for manufacturers who need to perform interoperable, multi-disciplinary analyses on ever-more complex products and assemblies.
Within this category we include our MD Nastran, MD Patran, and MD Adams products.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Enterprise SolutionsAn emerging approach to engineering analysis which integrates simulation to the enterprise and while managing the simulation
workflows and data to deliver repeatable, automated simulation processes early in the product design cycle. Within this category we include our SimEnterprise solutions of SimXpert, SimManager Enterprise, and SimDesigner Enterprise.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Channel ProductsDesigned to enable companies of any size to reap the many benefits of early, accurate design validation using computer simulation.
Within this category we include our SimOffice product.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

To support our long-term strategy in providing leading edge
enterprise simulation solutions, during 2006 we discontinued or terminated development, support and/or marketing of numerous non-strategic products and consulting services. In addition, we entered into a worldwide strategic alliance with IBM that
will embed and optimize IBM technology as part of our SimManager Enterprise solution to deliver high performance, enterprise scalability, storage flexibility and robust reliability and availability in an on demand world. This technology will also
permit our customers to take advantage of deploying an on demand enterprise built from reusable components that will help lower development costs and improve time to market.

We believe our strategy in providing our customers enterprise simulation solutions, including our enterprise simulation development platform 
SimEnterprise, and its related component solutions SimXpert, SimManager Enterprise and SimDesigner Enterprise, together with our MD software that delivers highly enhanced multi-disciplinary capabilities, will differentiate us from our
competition.

In addition to our new product strategy implemented in 2006, our management also focused on (i) improving global sales
execution; (ii) strengthening our relationships with our most significant customers; (iii) accelerating time-to-market for new products through increasing the productivity of our research and development organization; (iv) selling
more enterprise-wide transactions; (v) reducing our overhead and infrastructure costs; and (vi) improving our financial and management information systems and related processes.

We will continue to evaluate our business model, including our product mix and positioning, marketing
strategies and sales channels to maximize our market opportunities and to improve our operating results. We are committed to improving our cost structures and will continue to invest in or streamline our business operations as necessary to best
serve the marketplace and to successfully compete in all our geographic locations. On January 17, 2007, our Board of Directors approved the implementation of a cost reduction program that included a 7% reduction of our workforce and additional
facility closings and consolidations. We believe the cost reduction program will better align operating costs with our new enterprise sales strategy while allowing us to compete aggressively in all our markets and to improve operating profit. The
Company estimates that total costs related to the cost reduction program will be between $6.0 million and $8.0 million, which includes a charge for severance and termination benefits of between $5.0 million and $6.5 million and charges related to
facility closings and consolidations of between $1.0 million and $1.5 million. The Company expects such charges will be incurred and recognized in the first and second quarters of 2007.

Discontinued Operations

In the fourth quarter of
2005, we approved a plan to sell our wholly-owned Japanese service subsidiary, ESTECH Corporation (ESTECH). ESTECH was acquired in 2002 as part of the MDI acquisition and provides expert technical services, primarily in structural
dynamics, motion, vibration and acoustics to customers primarily in the automotive and precision electronics industries. Accordingly, all current and prior financial information related to ESTECH has been presented as discontinued operations in the
accompanying consolidated financial statements.

Included as part of the accounting for discontinued operations of ESTECH is a loss on
disposal of $1.1 million representing the accrued loss on the sale that was consummated in March 2006.

2006 Highlights

During 2006, we began aggressive marketing of our SimEnterprise solutions - SimDesigner, SimManager and SimXpert  as part of our enterprise
simulation solutions strategy. Our multi-disciplinary software products  MD Nastran, MD Patran and MD Adams  were also introduced to our customers as a valued-added alternative to certain of our legacy engineering products. The
transition from selling software tools to selling enterprise simulation solutions required extensive recruiting and training of sales personnel throughout our regions, as well as comprehensive presentations to key customers to demonstrate the
capabilities of these new solutions to manage their product design and engineering processes and simulation data more efficiently. The transition also required our major customers to re-evaluate their product engineering needs and to revise, review
and approve higher funding requirements. As a result, our experience to date shows that selling enterprise solutions generally lengthens the sales cycles, leading to delays in purchasing our products.

Our reported software revenue for 2006, particularly during the last six months of 2006, highlights the challenges we faced and continue to face during
this transition. Billings for our engineering products and our MasterKey token-based program were lower in 2006, partially offset by billings for our new MD software and enterprise solutions introduced in 2006. We believe the transition from selling
software tools to selling enterprise simulation solutions will accelerate in 2007 as market acceptance grows, ultimately leading to higher average orders and increased software revenue, while providing our customers a significant return on their
investment.

Total reported revenue for 2006 was $259.7 million, a decrease of 12.2% compared to $295.6 million for 2005. The 2005 period
included non-recurring revenue totaling $7.7 million related to our North American PLM business, which was sold in March 2006. Excluding the effects of changes in foreign currency rates during the 2006 period, and after adjusting the 2005 period for
the non-recurring PLM revenue, our total revenue in 2006 decreased 8.5% to $263.6 million. Deferred revenue at December 31, 2006 was $78.2 million compared to $94.6 million at December 31, 2005.

Our operating expenses increased 0.6% to $196.9 million compared to $195.8 million for 2005. Included in the 2006 period was a $4.6 million
gain recognized on the sale of certain assets of our PLM business. In addition, the 2006 period included $6.0 million of audit and non-recurring professional services fees incurred in connection with the 2005 audit, $6.0 million of
consulting expenses related to the implementation of a worldwide financial and management system, $5.3 million of additional stock based compensation recognized upon adoption of FAS 123(R) effective January 1, 2006 and $0.7 million to settle
previously disclosed claims. The 2005 period included $25.0 million of special investigation, severance, facility and department closures and consolidations and other non-recurring expenses, including $5.7 million of expenses related to North
American PLM business. Our operating margin during the 2006 period was 1.8% compared to 9.9% during the 2005 period.

Net cash used in
operations during 2006 was $4.5 million, a decrease of $44.6 million compared to cash provided by operations of $40.1 million during 2005. Our cash, cash equivalents and investments increased 12.2% to $126.0 million at December 31, 2006
compared to $112.3 million at December 31, 2005.

Critical Accounting Policies

Our consolidated financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). These accounting principles
require us to make estimates, judgments and assumptions that affect the reported amounts of revenue, costs and expenses, assets, liabilities and contingencies, and related disclosures. All significant estimates, judgments and assumptions are
developed based on the best information available to us at the time made and are regularly reviewed and updated when necessary. Actual results will generally differ from these estimates. Changes in estimates are reflected in our financial statements
in the period of change based upon on-going actual experience, trends or subsequent settlements and realizations depending on the nature and predictability of the estimates and contingencies.

The following accounting policies are considered to be critical in evaluating and understanding our financial results because they involve inherently
uncertain matters or their application requires the most significant and complex judgments and estimates.

Revenue Recognition

We derive revenue from licensing our software products and providing maintenance, consulting, and training services. Our standard software license
agreement is a perpetual license to use our products on an end user basis.

We record revenue from licensing our software products to end
users provided there is persuasive evidence of an arrangement, the fee is fixed or determinable, collection is reasonably assured and delivery of the product has occurred, as prescribed by Statement of Position (SOP) No. 97-2,
Software Revenue Recognition. For arrangements with multiple elements, and for which vendor specific objective evidence (VSOE) of fair value exists for the undelivered elements, revenue is recognized for the delivered
elements based upon the residual method in accordance with SOP 98-9, Modifications of SOP 97-2 with Respect to Certain Transactions. Amounts billed or payments received in advance of revenue recognition are recorded as deferred revenue.

Maintenance agreements are generally twelve-month prepaid contracts that are recognized ratably over the service period. VSOE of fair
value for maintenance is measured by the stated renewal rate included in the agreement or, when not stated in the agreement, VSOE is calculated based on actual, historical evidence.

Customers may also enter into arrangements for consulting and training services that are either on a time and materials basis or for a fixed fee. VSOE of
fair value for consulting and training services is based upon the standard hourly rate we charge for such services when sold separately. Training services are generally prepaid prior to rendering the service. Consulting and training revenue are
typically recognized as earned. Consulting revenue is generated primarily from implementation services related to the installation of our products and other VPD solutions. These arrangements are generally not essential to the functionality of the
software and are generally accounted for separately from the license revenue because the arrangements qualify as service transactions as defined in SOP 97-2. Our products are fully functional upon delivery of the product and
implementation does not require significant modification or alteration. Our consulting revenue under fixed fee arrangements is generally recognized using the percentage-of-completion method of contract accounting in accordance with SOP 81-1,
Accounting for Performance of Construction-Type and Certain Product-Type Contracts and Accounting Research Bulletin No. 45, Long-Term Construction-Type Contracts, which approximates the proportional performance method.
When percentage-of-completion accounting is not possible due to our inability to accurately calculate percentage-of-completion, we recognize revenue using the completed-contract method.

If the fair value of any undelivered element included in a multiple-element arrangement cannot be objectively determined, revenue is deferred until all
elements are delivered, services have been performed, or until fair value can be objectively determined. License revenue from agents is recognized upon sell-through to the end customer. If we determine that collection of a license fee is not
reasonably assured, the fee is deferred and revenue is recognized at the time collection becomes reasonably assured, which is generally upon receipt of cash.

If in the future we were unable to support VSOE of fair value for an undelivered element, the entire amount of revenue from the arrangement would be deferred and recognized ratably over the life of the contract.

Allowance for Doubtful Accounts

We maintain allowances for doubtful accounts for estimated losses resulting from the unwillingness or inability of our customers to make required
payments. This requires us to make estimates of future write-offs of bad debt accounts related to current period revenue. The amount of our allowances is based on historical experience and our current analysis of the collectibility of accounts
receivable. If the financial condition of our customers were to deteriorate, resulting in their inability to make payments, additional allowances may be required which would result in an additional general and administrative expense in the period
such determination was made. While such amounts have historically been within our expectations and the provisions established, we cannot guarantee that we will continue to experience the same credit loss rates that we have in the past. If for some
reason we did not reasonably estimate the amount of our doubtful accounts in the future, it could have a material impact on our consolidated results of operations.

Income Taxes

During the preparation of our consolidated financial statements, we estimate our income
taxes in each of the jurisdictions in which we operate. This process involves estimating actual current tax expense together with assessing temporary differences resulting from differing treatment of items, such as deferred revenue, for tax and
accounting purposes. These differences result in deferred tax assets and liabilities, which are included within the consolidated balance sheet. We then assess the likelihood that our deferred tax assets will be recovered from future taxable income,
and, to the extent we believe that recovery is not likely, a valuation allowance is established. To the extent we establish a valuation allowance or increase this allowance in a period, an expense is recorded within the tax provision in the
consolidated statements of operations.

Significant management judgment is required in determining the provision for income taxes, deferred
tax assets and liabilities, and any valuation allowance recorded against the net deferred tax assets. We record a valuation allowance when uncertainties exist as to our ability to utilize some of our deferred tax assets before they expire. The
valuation allowance is based on estimates of taxable income by jurisdiction in which we operate and the period over which the deferred tax assets will be recoverable. In the event that actual results differ from these estimates, or these estimates
are adjusted in future periods, additional valuation allowances may need to be recorded which could materially impact our financial position and results of operations.

Our accounting for income taxes also requires us to exercise judgment for issues relating to known matters under discussion with tax authorities and transactions yet to be settled. If material, we record tax
liabilities for known tax contingencies when, in our judgment, it is probable that a liability has been incurred and regularly assess the adequacy of this tax liability. It is reasonably possible that actual amounts payable resulting from audits by
tax authorities could be materially different from the liabilities we have recorded due to the complex nature of the tax legislation that affects us.

Valuation of Goodwill, Intangibles, and Long-Lived Assets

We account for goodwill under Statement of
Financial Accounting Standards SFAS No. 142, Goodwill and Other Intangible Assets, which requires us to review for impairment of goodwill on an annual basis and between annual tests whenever events or changes in circumstances
indicate that the carrying amount may not be recoverable. This impairment review involves a two-step process as described in Note 1 in Notes to Consolidated Financial Statements. Based upon our management of resources, we have determined that we
have two reporting unitssoftware and services, and we are required to make estimates regarding the fair value of each reporting unit when testing for potential impairment. We estimate the fair value of our reporting units using the income
approach.

We account for finite-lived intangibles and long-lived assets under SFAS 144, Accounting for the Impairment or Disposal of
Long-Lived Assets, which requires us to review for impairment of long-lived assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Factors considered important which could
trigger an impairment review include (1) significant underperformance relative to historical or projected future operating results, (2) significant changes in the manner of use of the assets or the strategy for our overall business,
(3) significant decrease in the market value of the assets, and (4) significant negative industry or economic trends. Costs allocated to acquired in-process research and development (IPR&D) are charged to operations on the
acquisition date.

Assets to be disposed of are separately presented in the consolidated balance sheet and reported at the lower of the
carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposed group classified as held for sale would be presented separately in the appropriate asset and liability sections of the
consolidated balance sheets, if material.

Contingencies and Litigation

We may, from time to time, be subject to various proceedings, lawsuits and claims relating to products and services, technology, labor, shareholder and
other matters. We are required to assess the likelihood of any adverse outcomes and the potential range of probable losses in these matters. If the potential loss is considered probable and the amount can be reasonably estimated, we accrue a
liability for the estimated loss. If the potential loss is considered less than probable or the amount cannot be reasonably estimated, disclosure of the matter is considered. The amount of loss accrual or disclosure, if any, is determined after
analysis of each matter, and is subject to adjustment if warranted by new developments or revised strategies. Due to uncertainties related to these matters, accruals or disclosures are based on the best information available at the time. Significant
judgment is required in both the assessment of likelihood and in the determination of a range of potential losses. Revisions in the estimates of the potential liabilities could have a material impact on or consolidated financial position or
consolidated results of operations.

Recently Adopted Accounting Standards

In September 2006, the Securities and Exchange Commission issued Staff Accounting Bulletin (SAB) No. 108, Considering the
Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements, which is effective for fiscal years ending after November 15, 2006. SAB No. 108 requires an entity to evaluate the impact of
correcting all misstatements, including both the carryover and reversing effects of prior year misstatements, on current year financial statements. If a misstatement is material to the current year financial statements, the prior year financial
statements should also be corrected, even though such revision was, and continues to be, immaterial to the prior year financial statements. Correcting prior year financial statements for immaterial errors would not require previously filed reports
to be amended. Such correction should be made in the current period filings. We completed our evaluation of uncorrected differences pursuant to SAB 108, and concluded that no cumulative effect transition adjustment was necessary.

In September 2006, the FASB issued SFAS No. 158, Employers Accounting for Defined Benefit Pension and Other Postretirement Plans
 an amendment of FASB Statement No. 87, 88, 106 and 132(R). SFAS No. 158 requires an employer that sponsors one or more single-employer defined benefit plans to: 1) recognize the funded status of a benefit plan; 2)
recognize as a component of other comprehensive income, net of tax, the gains or losses and prior service costs or credits that arise during the period, but are not recognized as components of net periodic benefit cost pursuant to FASB Statement
No. 87, Employers Accounting for Pensions, or No 106, Employers Accounting for Postretirement Benefits Other Than Pensions; 3) measure defined benefit plan assets and obligations as of the date of the
employers fiscal year ended statement of financial position; and 4) disclose in the notes to financial statement additional information about certain effects on the net periodic benefit cost for the next fiscal year that arise from delayed
recognition of the gains or losses, prior service costs or credits, and transition asset or obligation. SFAS No. 158 will require an employer to initially recognize the funded status and provide the required disclosure as of the end of fiscal
year ending after December 15, 2006. Accordingly, we adopted SFAS No. 158 for the year ended December 31, 2006, the effects of which are disclosed in Note 9 to Consolidated Financial Statements.

In February 2006, the FASB issued FASB Staff Position (FSP) No. SFAS 123(R)-4 Classification of Options and Similar Instruments
Issued as Employee Compensation That Allow for Cash Settlement upon the Occurrence of a Contingent Event. FSP SFAS 123(R)-4 addresses the classification of options and similar instruments issued as employee compensation that allow for cash
settlement upon the occurrence of a contingent event and amends paragraphs 32 and A229 of SFAS No. 123(R). We were required to apply the guidance in FSP SFAS 123(R)-4 in the quarterly period ended March 31, 2006. Such adoption of FSP SFAS
123(R)-4 did not impact our consolidated financial statements included in this report.

Effective January 1, 2006, the Company adopted the
fair value recognition provisions of SFAS No. 123(R), Share-Based Payment, which is a revision of SFAS No. 123. SFAS No. 123(R) supersedes Opinion 25, and amends SFAS No. 95, Statement of Cash Flows. Under SFAS
No. 123(R), compensation cost for all stock-based awards, including grants of employee stock options, restricted stock and other equity awards, are measured at fair value at date of grant and recognized as compensation expense on a straight line
basis over the service period that the awards are expected to vest. In addition, SFAS No. 123(R) requires the benefits of tax deductions in excess of recognized compensation expense to be reported as a financing cash flow, rather than as an
operating cash flow as prescribed under previous accounting rules. In its adoption, the Company elected to use the modified prospective method, which recognized compensation expense for all share-based payments granted after January 1, 2006 and for
all awards granted to employees prior to January 1, 2006 that remain unvested on the date of adoption. Accordingly, prior period amounts have not been restated. See Note 1 to Consolidated Financial Statements.

In November 2005, the FASB issued FSP No. SFAS 123(R)-3, Transition Election Related to Accounting for the Tax Effects of Share-Based Payment
Awards, which allows an entity up to one year from the later of its initial adoption of FAS 123(R) or the effective date of FSP SFAS 123(R)-3 to evaluate its available transition alternatives in calculating the pool of excess tax benefits
available to absorb tax deficiencies recognized subsequent to the adoption of SFAS No. 123 for recognition purposes (the APIC pool) and to make its one-time election. We elected to apply the alternative transition method under
SFAS 123(R)-3 to calculate the tax effects of stock-based compensation under SFAS 123(R) as of December 31, 2005. The alternative transition method includes simplified methods to establish the beginning balance of the APIC pool
related to the tax effects of employee stock-based compensation expense, and to determine the subsequent impact on the APIC pool and consolidated statements of cash flows of the tax effects of employee stock-based compensation awards outstanding at
the adoption of SFAS 123(R). We computed an APIC Pool of $0 at adoption of SFAS 123(R).

Recently Issued Accounting Standards

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurement. This statement defines fair value, establishes a framework for measuring fair value in generally accepted accounting
principles (GAAP), and expands disclosures about fair value measurements. It also applies under other accounting pronouncements that require or permit fair value measurement as a relevant attribute. SFAS No. 157 is effective for financial
statements issued for fiscal years beginning after November 15, 2007, and all interim periods within that fiscal year. The Company is evaluating what effect the adoption of SFAS No. 157 will have on the Companys consolidated results
of operations and financial condition.

In June 2006, FASB issued Interpretation No. 48, Accounting for Uncertainty in Income
Taxes, an interpretation of FAS 109, Accounting for Income Taxes (FIN 48), to create a single model to address accounting for uncertainty in income tax positions. FIN 48 clarifies the accounting for income taxes by prescribing a minimum
probability threshold a tax position must meet to be recognized in the financial statements. FIN 48 also provides guidance on the measurement, derecognition and classification of recognized tax benefits, interest and penalties, accounting for
interim periods, and the transition of the accounting method upon the adoption of FIN 48. It also requires footnote and tabular disclosures about unrecognized tax benefits. FIN 48 is effective for years beginning after December 15, 2006. We
will adopt FIN 48 in the first quarter of 2007 and record the cumulative effect of adopting FIN 48 in retained earnings and other accounts, as applicable, as of January 1, 2007. Certain tax account classifications on our balance sheet may
change to account for the differences in taxes payable and deferred tax assets calculated under FIN 48. The Company is currently evaluating what effect the adoption of FIN 48 will have on the Companys consolidated financial statements.

Revenue Background

We generate our revenue from the sale of software licenses, maintenance and consulting and training
services. We recognize revenue from software licenses, maintenance and services agreements at varying times. In general, we recognize revenue on a paid up software license in the month in which the license is shipped and on a time-based software
license monthly over the license term. Maintenance revenue, generated either as an element of a software license or by a separate renewal agreement, is recognized ratably over the maintenance period (normally one year). Consulting and training
agreements generally generate revenue upon completion and customer acceptance of contractually agreed milestones or upon providing the service. A more complete description of our revenue recognition policy can be found above under Critical
Accounting Policies.

Our revenue in any reporting period is equal to the sum of our software license, maintenance and services revenue for
the period. Software revenue includes revenue derived from paid up transactions recorded and shipped during the quarter and from lease arrangements received and delivered in prior quarters. Maintenance revenue in any quarter is derived from paid up
and renewal agreements received in prior quarters since our maintenance orders generally yield revenue ratably over a term of one year. Consulting and training revenue is derived from orders received in prior quarters, since we recognize revenue
from those services when they are delivered and accepted, not when they are booked. Revenue not recognized in a given reporting period is deferred accordingly.

Due to the cyclical nature of new product releases and spending by larger global accounts, our revenue is sensitive to individual large transactions that are neither predictable nor consistent in size or timing. No
single customer or reseller represented more than 10% of total revenue during the periods presented.

Total Revenue

Total revenue decreased 12.2% in 2006 to $259.7 million compared to $295.6 million in 2005 primarily as a result of lower software and services revenue
recognized in all our regions. Excluding the effects of changes in foreign currency rates during the 2006 period, and after adjusting the 2005 period for non-recurring PLM revenue totaling $7.7 million, our total revenue decreased 8.5% to $263.6
million.

Total revenue increased 10.6% in 2005 compared to 2004. The growth in revenue in 2005 was due to
increases in both software and maintenance and services revenue offset by unfavorable changes in foreign currency exchange rates.

The
change in foreign currency exchange rates unfavorably affected total revenue in 2005 by approximately $2.4 million due to the strengthening of the U.S. Dollar relative to the Japanese Yen and favorably affected total revenue in 2004 by
approximately $13.8 million due to the increase in strength of the Euro and Japanese Yen against the U.S. dollar.

Software
Revenue. Software revenue in 2006 decreased 22.8% to $111.2 million compared to $144.0 million in 2005. The decrease was associated with lower software revenue in each of the regions. Such decreases were generally the result of our
transition to selling enterprise solutions that specifically caused delays in purchasing decisions by our major customers. We believe that selling higher valued enterprise solutions generally lengthen the overall sales cycles. In addition, software
revenue in the Americas decreased due to the sale of our PLM assets in March 2006. As a percent of total revenue, software revenue was 42.8% in 2006 compared to 48.7% in 2005. Excluding the effects of changes in foreign currency rates during the
2006 period, and after adjusting the 2005 period for the PLM software revenue totaling $4.5 million, software revenue decreased 19.0% to $113.1 million.

Software revenue increased 12.9% to $144.0 million in 2005 compared to $127.5 million in 2004 due to increased penetration within the aerospace and automotive industries in EMEA. As a percent of total revenue,
software revenue was 48.7% in 2005 and 47.7% in 2004. In constant dollar terms software revenue increased 14.3% in 2005 to $145.7 million.

Maintenance and Services Revenue. Maintenance and services revenue in 2006 decreased 2.0% to $148.5 million compared to $151.6 million in 2005. Maintenance revenue increased 7.1% to $115.1 million primarily due to the
incremental growth in our installed customer base and high renewal rates. Services revenue decreased 24.4% to $33.4 million due to the nature, size and timing of consulting and training arrangements provided to our larger global accounts and the
loss of services revenue attributable to our North American PLM business. In addition, we have restructured our consulting business by discontinuing certain low value services. As a percent of total revenue, maintenance revenue was 44.3% and
services revenue was 12.8% in 2006 compared to 36.4% and 14.9%, respectively, in 2005. Excluding the effects of changes in foreign currency rates during the 2006 period, and after adjusting 2005 for the PLM services revenue totaling $3.2 million,
maintenance and services revenue increased 1.4% to $150.6 million.

Maintenance and services revenue increased 8.5% to $151.6 million
in 2005 compared to 2004. Maintenance revenue increased 15.2% to $107.5 million in 2005 primarily due to year-over-year growth of our installed customer base in all our regions. Services revenue decreased 5.0% to $44.1 million primarily due to the
nature and timing of consulting services provided to our larger customers, particularly in the Americas and EMEA. As a percent of total revenue, maintenance and services revenue was 52.0% in 2005 and 52.3% in 2004. In constant dollar terms,
maintenance and services revenue increased 10.6% in 2005 to $154.5 million.

Revenue by Geography

Americas  Total revenue in the Americas in 2006 was $75.7 million, a decrease of 13.5% compared to $87.6 million in 2005. After adjusting
2005 for non-recurring software and services revenue totaling $7.7 million attributable to our North American PLM business, total revenue in the Americas decreased 5.3%. Our non-PLM software revenue decreased 12.4% to $25.7 million as a result of
delays in orders resulting from the transition to selling our MD and enterprise solutions, which impacted sales to major customers in our key industries. Maintenance revenue increased 11.7% to $38.0 million due to a growing installed customer base
with high renewal rates. Our non-PLM services revenue decreased 27.7% to $12.0 million due to a decrease in training and consulting arrangements, particularly larger global accounts in the aerospace and automotive sectors, due to the completion of
projects and discontinuance of services offered.

In 2005 software revenue decreased 4.1% compared to 2004 due to reduced corporate
technology spending and the reorganization of the Americas sales organization in the latter half of 2005. Maintenance and services revenue remained virtually unchanged due to increased maintenance revenue resulting from growth of their
installed customer base offset by lower revenues from consulting services provided to major customers in the aerospace and automotive industries.

EMEA - Total revenue in EMEA in 2006 was $103.4 million, a decrease of 9.8% compared to $114.7 million for the same period in 2005. The decrease was attributable to a 24.3% decrease in software revenue caused primarily by
nonrecurring conversions of leasing arrangements to paid up in 2005 and the transition to selling enterprise solutions to our major customers, partially offset by a 10.8% increase in maintenance revenue resulting from renewals and a growing
installed base and a 2.0% increase in services revenue. Excluding the effects of changes in the EURO during the 2006 period, total revenue in EMEA in 2006 was $102.5 million, a decrease of 10.6% compared to 2005.

In 2005 software revenue increased 37.6% compared to 2004 primarily due to further penetration of key
customers within the aerospace and automotive industries. In constant dollar terms software revenue increased 39.4% compared to 2004. Maintenance and services revenue increased primarily due to increased maintenance revenue due to growth of their
installed customer bases partially offset by lower consulting services revenue caused by changes in the nature and timing of completing such services. In constant dollars terms maintenance and services revenue increased 2.3% compared to 2004.

Asia Pacific - Total revenue in Asia Pacific in 2006 was $80.5 million, a decrease of 13.7% compared to $93.3 million in 2005.
Software revenue decreased 19.9% to $37.0 million caused primarily by the transition to selling enterprise solutions to our major Japanese customers, partially offset by revenue growth in countries outside Japan. Maintenance revenue was $35.6
million, virtually unchanged compared to $36.1 million in 2005. Services revenue decreased 29.2% to $7.9 million due to the timing of the completion of consulting projects. Excluding the effects of changes in the YEN during the 2006 period, total
revenue in Asia Pacific in 2006 was $85.4 million, a decrease of 8.5% compared to 2005.

In 2005 software revenue increased 1% compared to
2004 that was attributable to higher sales to automotive customers. In constant dollar terms software revenue increased 2.9% compared to 2004. Maintenance and services revenue increased 30.0% primarily due to increased maintenance revenue resulting
from growth of their installed customer bases. In constant dollars terms maintenance and services revenue increased 32.2% compared to 2004.

Costs and
Expenses

A significant amount of our costs and expenses are considered fixed and do not vary based upon revenue levels. Our most
significant fixed expenses include compensation, benefits and facilities, all of which are difficult to reduce quickly should our revenue levels not meet expectations. During the last several years, we have reevaluated our software and services
businesses and have scaled these operations in response to economic and market conditions. We have taken actions to reduce operating expenses and to improve operating margins, including the decision to sell our ESTECH subsidiary in 2005 and to sell
certain assets related to our PLM business in 2006, as well as initiating separate restructuring plans in 2002 and 2003. During the second half of 2005 we began to expand our software development activities in India through services provided by GSSL
as a cost effective solution to maintaining our leadership in simulation software. In addition, during 2006 we have identified and/or began several cost reduction initiatives, including outsourcing our production, manufacturing and distribution
capabilities, renegotiating third party royalty arrangements and IT software licensing and maintenance agreements, and transitioning to electronic delivery of our software.

We allocate facility expenses among our functional income statement categories based on headcount within each functional area. Annually, or upon a
significant change in headcount (such as a workforce reduction, realignment or acquisition) or other factors, management reviews the allocation methodology and the expenses included in the allocation pool.

Cost of Revenue

Cost of Software
Revenue. Cost of software revenue consists primarily of royalties payable to third parties for technology embedded in or licensed with our software products, amortization of developed technology and the cost of product packaging and
documentation materials. In 2006, cost of software revenue decreased 22.8% to $12.9 million compared to $16.7 million in 2005. The decrease was attributable primarily to the sale of the PLM business, lower royalty expenses resulting from
renegotiated agreements and changes in product mix, including termination of products previously subject to royalties, and lower packaging and shipping costs. As a percent of software revenue, cost of software revenue was 11.6% in 2006, unchanged
compared to 2005. After adjusting the 2005 period for non-recurring PLM cost of software revenue totaling $1.5 million, cost of software revenue in 2006 decreased 14.2% compared to 2005.

In 2005 cost of software revenue was essentially flat compared to 2004 at $16.7 million. Cost of software revenue as a percent of software revenue was
11.6% in 2005 and 13.1% in 2004.

Cost of Maintenance and Services Revenue. Cost of maintenance and services consists
primarily of personnel, outside consultancy costs and other direct costs required to provide post sales support, consulting and training services. Cost of maintenance and services revenue in 2006 decreased 16.1% to $45.2 million compared to $53.9
million in 2005. The decrease was primarily the result of lower salaries, wages and benefits attributable to a reduction of personnel, lower accruals for incentive compensation, lower facility related expenses and the sale of the PLM business. As a
percent of maintenance and services revenue, cost of maintenance and services revenue decreased to 30.4% in 2006 from 35.6% in 2005 as a result of lower utilization rates and timing of costs incurred in providing consulting and training services
versus the recognition of related revenue by our EMEA and Asia Pacific regions under completed contract accounting. Excluding the effects of changes in foreign currency rates during the 2006 period, and after adjusting the 2005 period for
non-recurring PLM cost of services revenue totaling $1.0 million, cost of maintenance and services revenue decreased 13.5% to $45.8 million.

##### Table of Contents

In 2005 cost of maintenance and services revenue decreased 3.1% to $53.9 million compared to 2004.
The decrease in cost of maintenance and services revenue in 2005 compared to 2004 was principally due to decreases in compensation related expenses. In constant dollar terms, cost of maintenance and services revenue decreased approximately 2.4% to
$54.3 million. Cost of maintenance and services revenue as a percent of maintenance and services revenue decreased to 35.6% in 2005 from 39.8% in 2004 due to improved utilization rates.

Operating Expenses

Total operating expenses in 2006 increased 0.6% to $196.9 million compared
to $195.8 million in 2005. Included in the 2006 period was a $4.6 million gain recognized on the sale of certain assets of our PLM business. In addition, the 2006 period included $6.0 million of audit and non-recurring professional services fees
incurred in connection with the 2005 audit, $6.0 million of consulting expenses related to the implementation of a worldwide financial and management system, $5.3 million of additional stock based compensation recognized pursuant to FAS 123(R)
and $0.7 million to settle previously disclosed claims. The 2005 period included expenses totaling $8.6 million related to the special investigation and the 2004 restatement audit, a provision of $4.8 million related to the closure and
consolidation of facilities and certain departments, severance expense totaling $3.9 million related to terminated officers, and $2.0 million of expense incurred in connection with the termination of a product and distribution agreement.
As a percent of total revenue, total operating expenses increased to 75.8% in 2006, from 66.2% in 2005. Excluding the effects of changes in foreign currency rates during the 2006 period, and after adjusting the 2005 period for non-recurring PLM
operating expenses totaling $5.7 million, total operating expenses increased 4.2% to $198.0 million.

Research and
Development.Our research and development expenses consist primarily of salaries and benefits, facility expenses, contracted services, incentive compensation and computer technology. Major research and development activities include
developing our enterprise solutions strategy, including our MD software, and enhancing the features and functionality of existing engineering products. Research and development expenses in 2006 decreased 8.7% to $43.2 million compared to $47.3
million in 2005 due to lower employee related expenses, including incentive compensation, and facility costs. As a percent of total revenue, research and development expenses were 16.7% in 2006 compared to 16.0% in 2005.

Research and development expenses increased 12.4% to $47.3 million in 2005, or 16.0% of revenue, from $42.1 million in 2004, or 15.8% of revenue.
The increase was attributable to higher compensation and benefits primarily due to annual salary increases, higher incentive compensation expenses and increases in our research and development headcount, especially in India. In addition, 2004
included a write off of $0.3 million of acquired in-process research and development costs in connection with the acquisition of SOFY Technologies Corporation. The projects associated with this charge were completed by the end of 2004.

Selling, General and Administrative.Our selling expenses consist primarily of salaries and benefits, sales commissions, facility costs,
travel and entertainment, incentive compensation, product marketing, and professional services. General and administrative expenses consist primarily of salaries, benefits and incentive compensation of administrative, executive, financial and legal
personnel, facility costs, outside consulting and other professional services and travel and entertainment. Selling, general and administrative expenses in 2006 increased 3.3% to $152.7 million compared to $147.8 million in 2005. Included in the
2006 period was a $4.6 million gain recognized on the sale of certain assets of our PLM business. In addition, the 2006 period included $6.0 million of audit and non-recurring professional services fees incurred in connection with the 2005 audit,
$6.0 million of consulting expenses related to the implementation of a worldwide financial and management system, $4.9 million of additional stock based compensation recognized pursuant to FAS 123(R) and $0.7 million to settle previously
disclosed claims. The 2005 period included expenses totaling $8.6 million related to the special investigation and the 2004 restatement audit, a provision of $4.8 million related to the closure and consolidation of facilities and certain
departments, severance expense totaling $3.9 million related to terminated officers, and $2.0 million of expense incurred in connection with the termination of a product and distribution agreement. The 2006 period was also impacted by
higher expenses for recurring audit and related services, increased travel and entertainment and product marketing expenses incurred in connection with our transition to selling enterprise simulation solutions, higher salaries, wages and benefits,
and a lease termination charge of $0.6 million resulting from our decision to outsource certain production, manufacturing and distribution capabilities, partially offset by lower accruals for incentive compensation. As a percent of total revenue,
selling, general and administrative expenses increased to 58.8% in 2006 from 50.0% in 2005. Excluding the effects of changes in foreign currency rates during the 2006 period, and after adjusting the 2005 period for non-recurring PLM expenses
totaling $5.7 million, selling, general and administrative expenses increased 8.3% to $153.8 million.

##### Table of Contents

Selling, general and administrative expenses increased 9.2% to $147.8 million in 2005, or 50.0% of
revenue, compared to $135.4 million, or 50.7% of revenue, in 2004. Included in these expenses were non-recurring expenses related to the independent investigation and restatement audit totaling $8.6 million and $8.1 million in 2005 and 2004,
respectively; severance and related expenses related to the termination of departing officers of $3.9 million and $0.9 million in 2005 and 2004, respectively; costs related to the closure and consolidation of facilities and certain departments
aggregating $4.8 million in 2005, and payments of $2.0 million related to the termination of a product and distribution agreement in 2005. In addition, selling, general and administrative expenses for 2005 were impacted by higher salaries and wages,
benefits, sales commissions and incentive compensation, including stock-based compensation of $4.5 million in 2005 and $3.3 million in 2004, and lower facility related costs compared to 2004. In constant dollar terms, selling, general and
administrative expenses increased 6.7% to $144.5 million in 2005.

Amortization of Intangibles. Amortization of
intangibles, primarily related to customer lists with useful lives ranging from five to fifteen years, was $0.8 million in 2006, 2005 and 2004.

Impairment Charges. In 2006 and 2004, we recognized impairment charges for assets held for sale.

Interest and Other (Income)
Expense, Net

Interest expense consists of interest on our long-term debt and the amortization of debt issue costs and discounts.
Interest expense in 2006 was $3.6 million compared to $4.4 million in 2005 and $4.6 million in 2004. The decrease in 2006 is attributable to the redemption of our Convertible Notes in June 2006, partially offset by a write off of related debt issue
costs totaling $1.4 million.

Other expense (income) includes interest income, foreign currency transaction gains and losses resulting from
the remeasurement of intercompany accounts denominated in the functional currency of the foreign subsidiary, and other non-operating income and expense. Other income, net in 2006 increased to $5.3 million compared to $0.9 million in 2005 due to the
recognition of foreign currency transaction gains versus foreign currency transaction losses in 2005 and higher interest income resulting from higher cash balances and rising interest rates. Other income declined in 2005 compared to 2004 primarily
due to a $2.6 million unfavorable impact from foreign currency transactions.

Provision for Income Taxes

The relative proportions of our domestic and foreign revenue and income directly affect our effective tax rate. We are also subject to changing tax laws
in the multiple jurisdictions in which we operate. As of December 31, 2006, current deferred tax assets, net of current deferred tax liabilities, totaled $15.7 million. Non-current deferred tax assets, net of non-current deferred tax
liabilities, totaled $4.8 million. We believe it is more likely than not that our results of future operations will generate sufficient taxable income to utilize our net deferred tax assets of $20.5 million. We consider future taxable income and
ongoing prudent and feasible tax planning strategies in assessing the need for any valuation allowance, and if we determine we would not be able to realize all or part of our net deferred tax assets in the future, we would record a charge to income
and an adjustment to the deferred tax assets in the period we make that determination.

We have not provided taxes for undistributed
earnings of our foreign subsidiaries because we plan to reinvest such earnings indefinitely outside the United States. If the cumulative foreign earnings exceed the amount we intend to reinvest in foreign countries in the future, we would provide
taxes on such excess amount. As of December 31, 2006, there was approximately $20.9 million of earnings upon which income taxes have not been provided.

Our effective tax rate, based on taxable income by regional tax jurisdiction, was <108.1>% in 2006 compared to 53.7% in 2005 and 36.3% in 2004. The negative rate in 2006 primarily resulted from the release of
valuation allowances established against domestic deferred tax assets, aggregating $12.7 million. The increase in the effective tax rate during 2005 reflect the impact of foreign earnings on consolidated earnings, foreign tax rate variances and
changes in valuation allowances established against domestic deferred tax assets.

Discontinued Operations

In March 2006, we completed the sale of our wholly owned Japanese service subsidiary, ESTECH Corporation, which has been accounted for as a discontinued
operation within the consolidated financial statements.

As of December 31, 2006, our principal sources of liquidity included cash and cash
equivalents of $111.9 million and marketable equity securities available-for-sale of $14.1 million.

Our working capital (current assets
minus current liabilities) increased $36.5 million during 2006 to $98.4 million at December 31, 2006, and increased $41.2 million during 2005 to $61.9 million at December 31, 2005. The increases in working capital were primarily due to the
timing of cash receipts on billings and payment of accounts payable and accrued liabilities, including those related to restructuring activities and non-recurring expenses, and changes in deferred revenue. In the past, working capital needed to
finance our operations has been provided by cash on hand and by cash flow from operations. We believe that cash on hand and cash generated from operations will provide sufficient capital for normal working capital needs over the next twelve months.
Our ability to generate cash flows from operations is dependent on our ability to generate income from our operations, and effective cash management, including timely billing and collections of trade accounts receivable and payment of our expenses
primarily related to compensation, benefits, facilities, royalties and third party services. Outside of these expenses, we generally do not have a significant amount of vendor payables.

Our operations used $4.5 million in cash during 2006, compared to generating cash of $40.1 million in 2005 and $31.9 million in 2004. The decrease in
cash generated from operations during 2006 was primarily attributable to lower cash earnings and higher levels of disbursements related to income taxes, accounts payable and accrued liabilities, partially offset by higher collections of billings and
changes in deferred revenue. The increase in cash generated in 2005 was primarily attributable to higher cash earnings, and lower payments of accounts payable and accrued liabilities, partially offset by lower collections of billings and changes in
deferred revenue. Our days sales outstanding was 98 days at December 31, 2006, 79 days at December 31, 2005 and 90 days at December 31, 2004. Our days sales outstanding generally exceed 60 days due to the high proportion of billings
generated from our international operations, which generally have longer payment terms compared to the U.S. In addition, our days sales outstanding are also negatively impacted by the significant volume of sales transactions and invoicing that
occurs near the end of any given quarter.

During 2004, 2005 and 2006, our research and development expenditures totaled $42.1 million,
$47.3 million and $43.2 million, respectively, none of which was capitalized due to the short duration between technological feasibility and general availability of the new software to our customers. We expect to continue to invest a substantial
portion of our revenues primarily for the development of our new enterprise simulation solutions and integrated multi-disciplinary software. In 2007, we estimate our expenditures for research and development activities will be approximately $49
million.

As of June 16, 2006 (the Redemption Date) all of our
outstanding 21/2% Senior Subordinated Convertible Notes due 2008 were converted under a previously announced
notice to call such notes at a redemption price of 100% of principal outstanding, plus interest accrued and unpaid thereon to, but not including, the Redemption Date. Holders of the Notes converted their Notes to shares of our common stock, at a
conversion rate of 117.4398 shares of our common stock per $1,000 principal amount of the Notes.

Net cash provided by investing activities
was $11.2 million in 2006 and $27.1 million in 2005 compared to net cash used of $33.4 million in 2004. Our principal investing activities during 2006 included proceeds from the sale of our ESTECH subsidiary and the PLM assets totaling $14.5
million, net capital expenditures of $8.2 million and proceeds of $4.8 million received from the sale of pledged securities no longer needed after the conversion of our Subordinated Convertible Notes in June 2006. During 2005, our principal
investing activities included proceeds of $35.5 million received from sales of auction rate securities, purchases of investment securities totaling $7.5 million and capital expenditures of $2.3 million.

##### Table of Contents

Capital expenditures in 2006, 2005 and 2004 included purchases of computer equipment and related software
used in the development and support of our software products and business processes, including $4.0 million in 2006 related to the upgrade of our worldwide financial and management information systems that was substantially completed in 2006. In
2007, we estimate that our capital expenditures will total approximately $8.4 million and will be primarily for the purchase of computer equipment and related software used in our development and business processes.

On November 8, 2006, our Board of Directors authorized the repurchase of up to 1,250,000 shares of the Companys common stock from time to time
in open market or private transactions.

Net cash provided by financing activities was $5.7 million in 2006 and $0.6 million in 2005
compared to net cash used of $0.8 million in 2004. During 2006 our principal financing activities included proceeds from the exercise of stock options totaling $9.5 million, payments on capital lease obligations totaling $2.6 million, the repurchase
of 183,400 shares of common stock for $2.6 million and $1.3 million of excess tax benefits related to stock-based compensation. Principal financing activities in 2005 included proceeds from the exercise of stock options totaling $1.2 million and
payments on capital lease obligations totaling $0.6 million.

Our current debt service obligations consist of interest and principal
payments on the 8% Subordinated Notes Payable due June 17, 2009. As of December 31, 2006, annual principal payments will total $0.8 million in 2007 and 2008 and $6.4 million in 2009. We may engage in additional financing methods that we
believe are advantageous, particularly to finance potential acquisitions.

|ITEM 7A. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|-------- | ----------------------------------------------------------

We are exposed to the impact of foreign currency fluctuations and interest rate changes.

Foreign Currency Risk

International revenue represented 66.6%, 70.4% and 70.8%, of our total revenue for 2004, 2005 and 2006, respectively. International sales are made mostly
from our foreign sales subsidiaries in Europe and Asia Pacific and are typically denominated in the local currency of each country. These subsidiaries also incur most of their expenses in the local currency. Accordingly, all foreign subsidiaries use
the local currency as their functional currency.

Our exposure to foreign exchange rate fluctuations arises in part from intercompany
accounts in which cash from sales of our foreign subsidiaries are transferred back to the United States. These intercompany accounts are typically denominated in the functional currency of the foreign subsidiary in order to centralize foreign
exchange risk with the parent company in the United States. We are also exposed to foreign exchange rate fluctuations as the financial results of foreign subsidiaries are translated into United States Dollars in consolidation. As exchange rates
vary, these results, when translated, may vary from expectations and impact overall expected profitability. In 2006, a 5% change in both the EURO and Yen would have impacted our revenue by approximately $8.8 million and our income from continuing
operations by approximately $1.7 million.

We do not currently hedge any of our foreign currencies.

Interest Rate Risk

We do not have any variable interest rate borrowings and, accordingly, our exposure to market rate risks for changes in interest rates is limited. Refer to Note 1 in the accompanying Notes to Consolidated
Financial Statements discussing fair value of financial instruments.

We have not used derivative financial instruments in our investment
portfolio. We invest our excess cash primarily in debt instruments of U.S. municipalities and other high-quality issuers and, by policy, limit the amount of credit exposure to any one issuer. We protect and preserve our invested funds by limiting
default, market and reinvestment risk.

Investment Risk

As of December 31, 2006 our investments included only marketable equity securities. We periodically evaluate whether any declines in fair value of our investments are other-than-temporary, which may result in an
impairment of such assets. This evaluation consists of a review of qualitative and quantitative factors. We had no such impairments during 2004, 2005 or 2006. Refer to Note 1 in the accompanying Notes to Consolidated Financial Statement, discussing
fair value of financial instruments.

Our marketable equity securities consist entirely of stock in Geometric Software Solutions
Co. Ltd. (GSSL), a public company headquartered in India, which we use for certain software development projects. All unrealized gains and losses related to our investment in the stock of GSSL are recorded as a component of other
comprehensive income. In the event we decide to sell all or any part of the stock of GSSL, amounts realized from such sale, and any resulting gains or losses, would be dependent upon the market price of the stock at the time of sale. As of
December 31, 2006, we owned 5,200,000 shares of GSSL stock with an original cost of $68,000.

MSC.SOFTWARE CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 2006

NOTE 1NATURE OF OPERATIONS
AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of OperationsMSC.Software Corporation (MSC or the
Company) designs, produces and markets proprietary enterprise simulation solutions, including simulation software and related professional services. Our enterprise simulation solutions are used in conjunction with computer-aided
engineering to create a more flexible, efficient and cost effective environment for product development. Our products and services are marketed internationally to various industries, including aerospace, automotive and other industrial concerns,
computer and electronics manufacturers, biomedical, shipbuilding and rail.

Principles of ConsolidationThe consolidated
financial statements include the accounts of the Company and its subsidiaries. All intercompany accounts and transactions have been eliminated.

The Company completed an acquisition in 2004. The results of the operations of the acquired company have been included in the consolidated statements of operations from the date of acquisition. Refer to Note 2Business Acquisitions.

Use of EstimatesThe preparation of financial statements in conformity with generally accepted accounting principles in
the United States (GAAP) requires management to make estimates and judgments that significantly affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities.
Significant estimates include those related to revenue recognition, accounts receivable allowances, income taxes, valuation of long-lived assets, and certain accrued liabilities, among others. Actual results could differ from those estimates, and
such differences could affect the results of operations reported in future periods.

Revenue RecognitionWe derive
revenue from licensing our software products and providing maintenance, consulting, and training services. Our standard software license agreement is a perpetual license to use our products on an end user basis.

We record revenue from licensing our software products to end users provided there is persuasive evidence of an arrangement, the fee is fixed or
determinable, collection is reasonably assured and delivery of the product has occurred, in accordance with Statement of Position (SOP) No. 97-2, Software Revenue Recognition. For arrangements with multiple elements, and
for which vendor specific objective evidence (VSOE) of fair value exists for the undelivered elements, revenue is recognized for the delivered elements based upon the residual method in accordance with SOP 98-9, Modifications of
SOP 97-2 with Respect to Certain Transactions. Amounts billed or payments received in advance of revenue recognition are recorded as deferred revenue.

Maintenance agreements are generally twelve-month prepaid contracts that are recognized ratably over the service period. VSOE of fair value for maintenance is measured by the stated renewal rates included in the
agreements or, when not stated in the agreement VSOE is calculated based upon actual, historical evidence.

Customers may also enter into
arrangements that are typically on a time and materials basis for consulting and training services. VSOE of fair value for consulting and training services is based upon the standard hourly rate we charge for such services when sold separately.
Training services are generally prepaid prior to rendering the service. Consulting and training revenue are typically recognized as earned. Consulting revenue is generated primarily from implementation services related to the installation of our
products and other enterprise simulation solutions. These arrangements are generally accounted for separately from the license revenue because the arrangements qualify as service transactions as defined in SOP 97-2. Our services are
generally not essential to the functionality of the software. Our products are fully functional upon delivery of the product and implementation does not require significant modification or alteration. Our consulting revenue is generally recognized
using the percentage-of-completion method of contract accounting in accordance with SOP 81-1, Accounting for Performance of Construction-Type and Certain Product-Type Contracts and Accounting Research Bulletin No. 45,
Long-Term Construction-Type Contracts which approximates the proportional performance method. When percentage-of-completion accounting is not possible due to our inability to accurately estimate percentage-of-completion, we recognize
revenue using the completed-contract method.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



If the fair value of any undelivered element included in a multiple-element arrangement cannot be
objectively determined, revenue is deferred until all elements are delivered, services have been performed, or until fair value can be objectively determined. License revenue from agents is recognized upon sell-through to the end customer. If we
determine that collection of a license fee is not reasonably assured, the fee is deferred and revenue is recognized at the time collection becomes reasonably assured, which is generally upon receipt of cash.

If in the future we were unable to support VSOE of fair value for an undelivered element, the entire amount of revenue from the arrangement would be
deferred and recognized ratably over the life of the contract.

Revenue is derived through the Companys direct sales force, a network
of value-added resellers and other sales agents. Revenue from the sale of products by other sales agents, for which a commission is due to the sales agent, is reported as net revenue (gross sales price less commission due to the sales agent) earned
from the product sale. Revenue from the sale of products provided by other suppliers, for which a royalty is due to the suppliers, is reported as gross revenue earned from the product sale. Royalties due to these other suppliers are recorded as
royalty expense in cost of software revenue. The Company does not offer any rights of return, rebates, stock balancing rights or price protection on the Companys software products.

Deferred RevenueAs of December 31, 2005 and 2006, deferred revenue consisted of the following (in thousands):



|                                    |  |      |        |      |   |

|Deferred license revenue            |  |      | 36,377 |      |   | 25,101
|Deferred services and other revenue |  |      | 6,343  |      |   | 1,771 
|                                    |  |      |        |      |   |       
|Total deferred revenue              |  | $    | 94,625 |      | $ | 78,189
|                                    |  |      |        |      |   |       

Discontinued OperationsDuring the fourth quarter of 2005, the Company approved
a plan to sell its Japanese service subsidiary, ESTECH Corporation (ESTECH). In March 2006, the sale of ESTECH was completed. In 2003, the Company ceased operations of its Systems business. Accordingly, all current and prior financial
information related to ESTECH and the Systems business has been presented as discontinued operations in the accompanying consolidated financial statements. Refer to Note 15Discontinued Operations.

Cash and Cash EquivalentsThe Company considers investments with maturities of three months or less when purchased to be cash
equivalents.

InvestmentsMarketable equity securities and debt securities are classified as trading, held-to-maturity
or available-for-sale in accordance with SFAS 115, Accounting for Certain Investments in Debt and Equity Securities. Management determines the appropriate classification of securities at the time of purchase and re-evaluates such
designation as of each balance sheet date. Available-for-sale securities are carried at fair value, with temporary unrealized gains and losses, net of tax, reported in shareholders equity as a separate component of accumulated other
comprehensive income (loss) in the consolidated balance sheets, until realized.

As of December 31, 2005 and 2006, all of our
short-term investments were classified as available-for-sale. Even though the stated maturity dates of these investments may be one year or more beyond the balance sheet dates, we have classified all marketable investments as short-term investments
as they are available for current operations. Realized gains and losses on sales of investment securities and declines in value judged to be other than temporary are included in other expense (income) in the consolidated statements of operations.
The cost of securities sold is based on the specific identification method.

Our debt securities held in 2005 were classified as
held-to-maturity and were reported at amortized cost in the consolidated balance sheets as other assets. Such debt securities are referred to as pledged securities in connection with our Convertible Notes. Refer to Note 7Long-Term Debt.

The pledged securities classified as held-to-maturity debt securities as of December 31, 2005
were sold in connection with the redemption of Convertible Notes in June 2006. Refer to Note 7  Long-Term Debt for further discussion.

We had no contractual maturities of any equity or debt securities as of December 31, 2005 and 2006.

Allowance for
Doubtful AccountsWe maintain allowances for doubtful accounts for estimated losses resulting from the unwillingness or inability of our customers to make required payments. This requires us to make estimates of future write-offs of bad
debt accounts related to current period revenue. The amount of the allowance is based on historical experience and our current analysis of the collectibility of accounts receivable. If the financial condition of our customers were to deteriorate,
resulting in their inability to make payments, additional bad debt provisions may be recorded in the period such determination was made.

Our allowance for doubtful accounts at December 31, 2005 and 2006 was $1,296,000 and $1,555,000, respectively. Our provision for doubtful accounts totaled $991,000, $498,000 and $625,000 in 2004, 2005 and 2006, respectively, and were
recorded in selling, general and administrative expense in the consolidated statements of operations. Uncollectible trade accounts receivable written-off, net of recoveries, were $91,000, $2,515,000 and $366,000 in 2004, 2005 and 2006, respectively.

use, are recorded at cost, less accumulated depreciation and amortization. Depreciation is computed on the straight-line method over the estimated useful lives of the assets, ranging from two to five years. Amortization of leasehold improvements is
calculated on the straight-line method over the shorter of the estimated useful lives of the assets or the corresponding lease term. Refer to Note 3Property and Equipment.

Software for internal use is capitalized in accordance with SOP 98-1, Accounting for the Cost of Computer Software Developed or Obtained for
Internal Use. Costs for purchased software and internal software development activities are capitalized beginning when the Company has determined (1) that technology exists to achieve the performance requirements, (2) buy versus
internal development decisions have been made and (3) the Companys management has authorized the funding for the project. Capitalization of software costs ceases when the software is substantially complete and is ready for its intended
use and is amortized over its estimated useful life of two years using the straight-line method. Amounts capitalized during 2005 and 2006 totaled $178,000 and $3,556,000, respectively.

Long-Lived AssetsWe evaluate the recoverability of our long-lived assets, including property and equipment and certain identifiable
intangible assets, in accordance with SFAS 144, Accounting for the Impairment or Disposal of Long-Lived Assets. SFAS 144 requires the Company to review for impairment of long-lived assets whenever events or changes in circumstances
indicate that the carrying amount of an asset may not be recoverable. Factors considered important which could trigger an impairment review include:



| |  |  | Significant underperformance relative to historical or projected future operating results;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | Significant changes in the manner of use of the assets or the strategy for our overall business;
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | Significant decrease in the market value of the assets; and
| | - |  | -----------------------------------------------------------



| |  |  | Significant negative industry or economic trends.
| | - |  | -------------------------------------------------

When we determine that the carrying amount of long-lived assets may not be recoverable based upon the existence of one or more of the above indicators, we assess the assets for impairment based on the estimated future
undiscounted cash flows expected to result from the use of the asset and its eventual disposition. If the carrying amount of an asset exceeds its estimated future undiscounted cash flows, an impairment loss is recorded for the excess of the
assets carrying amount over its fair value. Fair value is generally determined based on the estimated future discounted cash flows over the remaining useful life of the asset using a discount rate determined by our management to be
commensurate with the risk inherent in our current business model. The assumptions supporting the cash flows, including the discount rates, are determined using managements best estimates as of the date of the impairment review. If these
estimates or their related assumptions change in the future, the Company may be required to record additional impairment charges for these assets, and future results of operations could be adversely affected.

Assets to be disposed of are separately presented in the consolidated balance sheet and reported at the lower of the carrying amount or fair value less
costs to sell, and are no longer depreciated. The assets and liabilities of a disposed group classified as held for sale would be presented separately in the appropriate asset and liability sections of the consolidated balance sheets, if material.
In addition to the assets of ESTECH, which have been presented as part of discontinued operations, long-lived assets with a net book value of $200,000 (after a write-down of $141,000) were held for sale and classified as other current assets.

Goodwill and Other Indefinite Lived IntangiblesWe account for goodwill and other indefinite lived intangibles under
SFAS 142, Goodwill and Other Intangible Assets, which requires the Company to review for impairment of the intangible asset on an annual basis, and between annual tests whenever events or changes in circumstances indicate that the
carrying amount may not be recoverable. This impairment review involves the following two-step process:



| |  |  | Step 1Compare the fair value of our reporting units to the carrying value, including goodwill, of each of those units. If a units fair value exceeds the
carrying value, no further work is performed and no impairment charge is necessary. For each reporting unit where the carrying value, including goodwill, exceeds the units fair value, Step 2 is required.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Step 2Allocate the fair value of the reporting unit to its identifiable tangible and non-goodwill intangible assets and liabilities. This will derive an
implied fair value for the reporting units goodwill. Compare the implied fair value of the reporting units goodwill with the carrying amount of the reporting units goodwill. If the carrying amount of the reporting units
goodwill is greater than the implied fair value of its goodwill, an impairment loss must be recognized for the excess.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



In calculating the impairment charge, the fair value of the impaired reporting unit would be
estimated using the income approach. Significant management judgment is required in determining the allocations required under this process and projecting cash flows. Any changes in the assumptions used in projecting cash flows or determining an
appropriate discount rate could impact the assessed value of an asset and result in an impairment charged equal to the amount by which its carrying value exceeds its actual or estimated fair value.

No impairment charges were recorded in 2004, 2005 and 2006 as a result of our impairment testing. Refer to Note 4Goodwill and Other Intangible
Assets.

Software Development CostsDevelopment costs for software to be sold or otherwise marketed are included in
research and development expenses as incurred. After technological feasibility is established, significant software development costs are capitalized and amortized on a straight-line basis over the estimated life of the software product. To date,
the period between achieving technological feasibility, which typically occurs when the beta testing commences on a working model, and the general availability of such software to our customers has been short. As a result, software development costs
qualifying for capitalization have been insignificant and we have not capitalized any software development costs.

Advertising
ExpenseThe cost of advertising is expensed as incurred. The Company incurred $1,087,000, $813,000 and $1,012,000 in advertising costs during the years ended December 31, 2004, 2005 and 2006, respectively.

Royalties to Third PartiesThe Company has agreements with third parties requiring the payment of royalties for sales of third party
products or inclusion of such products as a component of the Companys products. Royalties are charged to cost of software license revenue when incurred and totaled $6,658,000, $5,905,000 and $5,578,000 in 2004, 2005 and 2006, respectively.

Stock-Based Compensation For the years ended December 31, 2004, 2005 and 2006, the Company maintained stock plans
covering a broad range of potential equity grants including stock options, stock appreciation rights, restricted stock, performance stock, stock units, phantom stock and dividend equivalents. In addition, the Company sponsored an Executive Cash and
Bonus Plan (Bonus Plan), whereby certain amounts of bonus earned during a year are paid in common stock of the Company, and an Employee Stock Purchase Plan (ESPP), whereby eligible employees were entitled to purchase common
stock semi-annually, by means of limited payroll deductions, at a 10% discount from the fair market value of the common stock as of specific dates. The ESPP was qualified under Sections 421 and 423 of the Internal Revenue Code and was a
non-compensatory plan under APB Opinion No. 25. Since July 31, 2004, there have been no additional purchases of the Companys stock under the ESPP.

Effective January 1, 2006, the Company adopted the fair value recognition provisions of SFAS No. 123(R), Share-Based Payment, which is a revision of SFAS No. 123. SFAS
No. 123(R) supersedes Opinion 25, and amends SFAS No. 95, Statement of Cash Flows. Under SFAS No. 123(R), compensation cost for all stock-based awards, including grants of employee stock options,
restricted stock and other equity awards, are measured at fair value at date of grant and recognized as compensation expense on a straight line basis over the service period that the awards are expected to vest. In addition, SFAS No. 123(R)
requires the benefits of tax deductions in excess of recognized compensation expense to be reported as a financing cash flow, rather than as an operating cash flow as prescribed under previous accounting rules. In its adoption, the Company elected
to use the modified prospective method, which recognized compensation expense for the fair value of all share-based payments granted after January 1, 2006 and for the fair value of all awards granted to employees prior to January 1, 2006
that remain unvested on the date of adoption. Accordingly, prior period amounts have not been restated.

Prior to January 1, 2006, the
Company accounted for stock-based awards using the intrinsic method in accordance with Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees and FASB Interpretation No. 44
(FIN 44), Accounting for Certain Transactions Involving Stock-Based Compensation, an Interpretation of APB Opinion No. 25 and related interpretations. Accordingly, the Company was not required to recognize compensation
expense for stock options granted or for shares issued under the ESPP. Prior to the adoption of SFAS No. 123(R), the Company recognized compensation expense only for restricted stock and restricted stock unit awards and for amounts earned under
the Bonus Plan.

Using the Black-Scholes option-pricing model, the estimated per share weighted-average fair value of
stock options granted in 2004, 2005 and 2006 was $5.29, $7.69 and $8.58, respectively. The estimated per share weighted-average fair value of ESSP shares purchased in 2004 was $2.07. These estimated per share fair values were determined using the
following weighted-average assumptions used for the periods indicated:



|                        |  |           |   |  |         |   |  |           |

The expected stock price volatility rates are based on historical volatilities of our common
stock. The risk-free interest rates are based on the U.S. Treasury yields in effect at the time of grant for periods corresponding with the expected life of the option. The expected life represents the weighted average period of time that
options granted are expected to be outstanding giving consideration to vesting schedules and our historical exercise patterns. For the year ended December 31, 2006, the average expected life was determined using the simplified approach
described under SAB 107.

In addition, we estimate forfeitures when recognizing compensation expense, and we will adjust our estimate
of forfeitures over the requisite service period based on the extent to which actual forfeitures differ, or are expected to differ, from such estimates. Changes in estimated forfeitures will be recognized through a cumulative catch-up adjustment in
the period of change and will also impact the amount of compensation expense to be recognized in future periods.

Income
TaxesThe Company uses the asset and liability method of accounting for income taxes. Provision is made in the Companys consolidated financial statements for current income taxes payable and deferred income taxes arising primarily
from temporary differences in accounting for intangible assets, capitalized software costs, deferred revenue, compensation and various state and federal tax credits. Deferred tax assets and liabilities are measured using enacted tax rates expected
to apply to taxable income in the years in which those temporary differences are expected to be realized or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the
enactment date. The Company records a valuation allowance to reduce deferred tax assets to an amount whose realization is more likely than not. Refer to Note 6Income Taxes.

Foreign CurrencyThe Company translates the assets and liabilities of its foreign subsidiaries at the rate of exchange in effect at
the end of the period. Revenue and expenses are translated using an average of exchange rates in effect during the period. Translation adjustments are recorded in shareholders equity as a separate component of accumulated other comprehensive
income (loss) in the consolidated balance sheets. Transaction gains and losses are included in net income in the period in which they occur.

Our intercompany accounts are typically denominated in the functional currency of the foreign subsidiary. Gains and losses resulting from the remeasurement of intercompany receivables that we consider to be of a long-term investment nature
are recorded in accumulated other comprehensive income (loss) while gains and losses resulting from the remeasurement of intercompany receivables from those international subsidiaries for which we anticipate settlement in the foreseeable future are
recorded in the consolidated statements of operations. The aggregate foreign currency transaction (gains) and losses included in other expense (income) on the consolidated statements of operations were $(1,574,000), $1,279,000 and $(1,232,000) for
the years ended December 31, 2004, 2005 and 2006, respectively.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



Earnings (Loss) Per ShareEarnings (loss) per share is calculated in accordance
with SFAS No. 128,Earnings per Share. Under the provisions of SFAS No. 128, basic earnings (loss) per share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding for the period.
Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock, or resulted in the issuance of common stock. Diluted earnings per share
is computed by using the weighted-average number of common and potentially dilutive shares outstanding during each period. Potentially dilutive shares are not included in the per share calculations where their inclusion would be anti-dilutive. Refer
to Note 13Earnings (Loss) Per Share.

Other Comprehensive Income (Loss)Comprehensive income (loss) includes
foreign currency translation adjustments, unrealized gains and losses on marketable securities categorized as available-for-sale, and recognition of the funded status of its pension plans. Comprehensive income (loss) and its components are presented
in the accompanying consolidated statements of shareholders equity and comprehensive income (loss).

ConcentrationsFinancial instruments that potentially subject MSC to a concentration of credit risk are principally comprised of cash and cash equivalents, short-term investments, and accounts receivable. Regarding cash
equivalents and short-term investments, MSC only invests in instruments with investment grade credit ratings. We place our investments for safekeeping with high-credit-quality financial institutions and, by policy, limit the amount of credit
exposure from any one issuer.

The Company has historically derived a significant portion of its net revenue from computer software
products for use in computer-aided engineering. These products are expected to continue to account for a significant portion of net revenue for the foreseeable future. As a result of this revenue concentration, the Companys business could be
harmed by a decline in demand for, or in the prices of, these products as a result of, among other factors, any change in pricing model, a maturation in the markets for these products, increased price competition or a failure by the Company to keep
up with technological change.

In addition, the Company derives a significant portion of its revenue from the automotive and aerospace
industries. As a result of this concentration, the Companys business could be harmed if any one or more of these industries experienced economic difficulties.

For 2004, 2005, and 2006, we had no customers that accounted for 10% or more of total revenue. As of December 31, 2004, 2005 and 2006, we had no customers that accounted for 10% or more of gross accounts
receivable. MSC does not require collateral from its customers prior to granting credit.

Self-InsuranceThe Company is
self-insured for certain medical claims and benefits offered to our employees in the United States. Based on analysis of the historical data, the estimated cost of future claims as of December 31, 2005 and 2006 was $696,000 and $604,000,
respectively, which is reflected as an accrued liability in the accompanying consolidated balance sheets.

Fair Values of Financial
InstrumentsAt December 31, 2004, 2005 and 2006, the Companys financial instruments included cash and cash equivalents, trade receivables, marketable securities, accounts payable, notes payable to shareholders, subordinated
notes payable and subordinated convertible notes. The carrying amount of cash and cash equivalents, trade receivables and accounts payable approximates fair value due to the short-term maturities of these instruments. The estimated fair value of
marketable equity investments, debt securities and subordinated convertible notes were determined based on quoted market prices at year-end. The estimated fair value of the notes payable to shareholders and subordinated notes payable was determined
based on the present value of their future cash flows using a discount rate that approximates the Companys current borrowing rate.

Recently Adopted Accounting Standards

In September 2006, the Securities and Exchange Commission issued Staff Accounting Bulletin (SAB) No. 108, Considering the
Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements, which is effective for fiscal years ending after November 15, 2006. SAB No. 108 requires an entity to evaluate the impact of
correcting all misstatements, including both the carryover and reversing effects of prior year misstatements, on current year financial statements. SAB 108 does not change the requirements within SFAS 154,Accounting Changes and Error
Corrections, for the correction of an error in financial statements. If a misstatement is material to the current year financial statements, the prior year financial statements should also be corrected, even though such revision was, and
continues to be, immaterial to the prior year financial statements. Correcting prior year financial statements for immaterial errors would not require previously filed reports to be amended. Such correction should be made in the current period
filings. The SEC staff believes that registrants should quantify errors using both a balance sheet (iron curtain) and an income statement (rollover) approach and evaluate whether either approach results in quantifying a misstatement that, when all
relevant quantitative and qualitative factors are considered, is material. In the year of adoption, SAB 108 allows a one-time cumulative effect transition adjustment for errors that were not previously deemed material, but are material under the
guidance in SAB 108. Historically, the Company has evaluated uncorrected differences utilizing the rollover approach. The Company completed its evaluation of uncorrected differences pursuant to SAB 108, and concluded that no cumulative
effect transition adjustment was necessary.

In September 2006, the Financial Accounting Standards Board (FASB) issued SFAS
No. 158, Employers Accounting for Defined Benefit Pension and Other Postretirement Plans  an amendment of FASB Statement No. 87, 88, 106 and 132(R). SFAS No. 158 requires an employer that sponsors one or
more single-employer defined benefit plans to: a) recognize the funded status of a benefit plan; b) recognize as a component of other comprehensive income, net of tax, the gains or losses and prior service costs or credits that arise during the
period, but are not recognized as components of net periodic benefit cost pursuant to FASB Statement No. 87, Employers Accounting for Pensions, or No 106, Employers Accounting for Postretirement Benefits Other Than
Pensions; c) measure defined benefit plan assets and obligations as of the date of the employers fiscal year ended statement of financial position; and d) disclose in the notes to financial statement additional information about
certain effects on the net periodic benefit cost for the next fiscal year that arise from delayed recognition of the gains or losses, prior service costs or credits, and transition asset or obligation. SFAS No. 158 will require an employer to
initially recognize the funded status and provide the required disclosure as of the end of fiscal year ending after December 15, 2006. The Company has adopted the recognition and disclosure provisions of SFAS No. 158 as of
December 31, 2006, which are discussed in Note 9  Pensions and Other Employee Benefits. Because the Company had measured its plan assets and obligations as of the end of its fiscal year, the remeasurement provisions in SFAS No. 158
are not applicable.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



In February 2006, the FASB issued FASB Staff Position (FSP) No. SFAS 123(R)-4
Classification of Options and Similar Instruments Issued as Employee Compensation That Allow for Cash Settlement upon the Occurrence of a Contingent Event. FSP SFAS 123(R)-4 addresses the classification of options and similar
instruments issued as employee compensation that allow for cash settlement upon the occurrence of a contingent event and amends paragraphs 32 and A229 of SFAS No. 123(R). The Company was required to apply the guidance in FSP SFAS 123(R)-4 in
the quarterly period ended March 31, 2006. Such adoption of FSP SFAS 123(R)-4 did not impact the Companys consolidated financial statements included in this report.

In November 2005, the FASB issued FSP No. SFAS 123(R)-3, Transition Election Related to Accounting for the Tax Effects of Share-Based Payment
Awards, which allows an entity up to one year from the later of its initial adoption of FAS 123(R) or the effective date of FSP SFAS 123(R)-3 to evaluate its available transition alternatives in calculating the pool of excess tax benefits
available to absorb tax deficiencies recognized subsequent to the adoption of SFAS No. 123 for recognition purposes (the APIC pool) and to make its one-time election. The Company elected to apply the alternative transition method
under SFAS 123(R)-3 to calculate the tax effects of stock-based compensation under SFAS 123(R) as of December 31, 2005. The alternative transition method includes simplified methods to establish the beginning balance of the APIC pool
related to the tax effects of employee stock-based compensation expense, and to determine the subsequent impact on the APIC pool and consolidated statements of cash flows of the tax effects of employee stock-based compensation awards outstanding at
the Companys adoption of SFAS 123(R). The Company computed an APIC Pool of $0 at adoption of SFAS 123(R).

In addition, under
SFAS 123(R), SFAS No. 109, Accounting for Income Taxes, and EITF Topic D-32, Intraperiod Tax Allocation of the Tax Effect of Pretax Income from Continuing Operations, the Company has elected to recognize excess income
tax benefits from stock-based compensation in additional paid-in capital in the period, and to the extent, it will realize an incremental income tax benefit after realizing the benefits of all other tax attributes available to the Company.

Recently Issued Accounting Standards

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurement. This statement defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles (GAAP), and
expands disclosures about fair value measurements. It also applies under other accounting pronouncements that require or permit fair value measurement as a relevant attribute. SFAS No. 157 is effective for financial statements issued for fiscal
years beginning after November 15, 2007, and all interim periods within that fiscal year. The Company is evaluating what effect the adoption of SFAS No. 157 will have on the Companys consolidated results of operations and financial
condition.

In June 2006, FASB issued Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an interpretation of
FAS 109, Accounting for Income Taxes (FIN 48), to create a single model to address accounting for uncertainty in income tax positions. FIN 48 clarifies the accounting for income taxes by prescribing a minimum probability threshold a tax
position must meet to be recognized in the financial statements. FIN 48 also provides guidance on the measurement, derecognition and classification of recognized tax benefits, interest and penalties, accounting for interim periods, and the
transition of the accounting method upon the adoption of FIN 48. It also requires footnote and tabular disclosures about unrecognized tax benefits. FIN 48 is effective for years beginning after December 15, 2006. We will adopt FIN 48 in the
first quarter of 2007 and record the cumulative effect of adopting FIN 48 in retained earnings and other accounts, as applicable, as of January 1, 2007. Certain tax account classifications on our balance sheet may change to account for the
differences in taxes payable and deferred tax assets calculated under FIN 48. The Company is currently evaluating what effect the adoption of FIN 48 will have on the Companys consolidated financial statements.

NOTE 5RESTRUCTURING RESERVE

During 2002 and 2003, the Company initiated separate restructuring plans. The 2002 Plan was created as a result of weakened economic conditions in all
three world areas in which the Company operates. It was determined that workforce reductions and facility consolidations would be necessary to return the Company to profitability. In addition, the acquisition of Mechanical Dynamics, Inc.
(MDI) in 2002 created certain redundant expenses that needed to be eliminated. In accordance with EITF No. 95-3, Recognition of Liabilities in Connection with a Purchase Business Combination (EITF
95-3), the costs related to the integration of MDI were included as assumed liabilities in the net tangible assets acquired. Under the 2002 Plan, the Company terminated 310 employees and subleased or terminated the leases on certain
facilities. The 2003 Plan was initiated as further cost reductions were necessary to improve profitability and included the termination of 55 employees. A portion of the 2002 Plan has been reclassified to current liabilities of discontinued
operations. Refer to Note 15Discontinued Operations and Note 17  Subsequent Event.

In assessing the ability to realize deferred tax assets, management considers whether it is
more likely than not that some portion or all of the deferred tax assets will not be realized. Management considers taxable income in carryback years, the scheduled reversal of deferred tax liabilities, tax planning strategies, and
projected future taxable income in making this assessment. Based on the Companys history of cumulative income, management believes it is more likely than not that the Company will realize the benefit of the domestic and foreign net
deferred tax assets existing as of the taxable year ended December 31, 2006.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



In the fourth quarter of fiscal 2006, we completed an analysis of our inter-company transfer pricing,
which supported revising our intercompany transfer pricing retroactive to 2004. The revision reallocated a portion of consolidated pre-tax income from our foreign operations to domestic operations, and we concluded that we would more likely than not
realize our domestic deferred tax assets.

Accordingly, we released valuation allowances of $38,273,000 previously established against our
domestic deferred assets, of which $8,050,000 and $4,652,000 reduced federal and state income tax expense on earnings from continuing operations, respectively. Of the remaining valuation allowance released, $1,274,000 was credited to additional
paid-in-capital and $2,187,000 was credited to goodwill related to purchase accounting adjustments. As a result of our decision to permanently reinvest earnings of our foreign subsidiaries, we reduced deferred tax assets of $5,654,000 associated
with estimated foreign tax credits of such foreign subsidiaries. Accordingly, there was a corresponding decrease in our valuation allowance. The tax benefit associated with the release of an additional $8,029,000 of valuation allowance was fully
offset by an increase in our tax contingency reserve for the same amount. The remaining reduction of the valuation allowance of $8,427,000 primarily relates to adjustments to prior year intercompany transfer pricing as described above.

At December 31, 2006, deferred tax assets exclude $1,762,000 of net operating losses (NOLs), representing the tax-effected portion of
the NOLs pertaining to tax deductions from stock-based compensation. Upon future realization of these unrecognized benefits, the Company will increase additional paid-in-capital and decrease income taxes payable.

The Company uses the with-or-without method under SFAS 123(R) to determine when it will realize excess tax benefits from stock-based compensation. Under
this method, the Company will realize excess tax benefits only after it realizes the tax benefits of NOLs from operations.

At
December 31, 2006, the Company has total federal, state, and foreign NOLs, including those associated with excess tax benefits from share-based compensation, of $21,280,000, $8,711,000 and $6,904,000, respectively. Federal NOLs begin to expire
in 2026 and state NOLs begin to expire in 2016. Approximately $709,000 of the foreign NOLs begin to expire in years 2008 through 2011; the remaining $6,195,000 of foreign NOLs carry forward indefinitely until used.

At December 31, 2006, the Company had federal, state, and foreign income tax credit carry forwards of approximately $4,362,000, $4,871,000 and
$626,000, respectively. Federal income tax credits will expire at various dates from 2018 through 2026; state income tax credits have no expiration date; and foreign income tax credits expire at various dates from 2007 through 2017.

The Companys California income tax returns for the years ended December 31, 2001 and December 31, 2002 are under audit. Also its New York
income tax returns for the years ended December 31, 2003 through December 31, 2005 are under audit. The Company believes it has adequately reserved for the tax effects of any adjustments expected from these audits.

The following table reconciles the U.S. federal statutory tax rate to the combined effective tax rate for years ended December 31, 2004, 2005 and
2006.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



Although the Company has continuously reinvested the undistributed earnings of its foreign
subsidiaries for the expansion and working capital needs of those subsidiaries, it had no formal plan to do so prior to its fiscal year 2006. Effective January 1, 2006, the Company adopted a policy to indefinitely reinvest all accumulated and future
undistributed foreign earnings. As a result, the Company reversed previously recorded deferred tax liabilities associated with those earnings, deferred tax assets associated with creditable foreign income taxes of the Companys foreign
subsidiaries, and deferred tax assets related to cumulative translation adjustment gainsor losses. The Company has provided for no U.S. federal or state deferred tax liabilities on approximately $20.9 million of undistributed foreign
earnings at December 31, 2006. Determination of the potential amount of unrecognized deferred U.S. income tax liability and foreign withholding taxes is not practicable because of the complexities associated with its hypothetical calculation;
however, unrecognized foreign tax credits would be available to reduce some portion of the U.S. liability.

The following table depicts the
Companys foreign and domestic operations realized combined income (loss) from continuing operations before taxes, including inter-company charges that eliminate in consolidation for the years ended December 31, 2004, 2005 and 2006:

Subordinated Notes Payable

In June 1999, in connection with an acquisition, the Company issued subordinated notes payable in the aggregate principal amount of $14,236,000. The subordinated notes payable were recorded at their estimated
fair value at the time of issuance, net of a discount of $2,596,000. The subordinated notes payable bear interest at 8% with interest payments due semi-annually in January and July. The unamortized discount is being amortized to interest
expense using the effective-interest method over the term of the notes payable. The principal balance will be paid in equal installments of $800,000 in June 2007 and June 2008 with the remaining balance due in June 2009.

Senior Subordinated Convertible Notes

In May 2003, the Company sold $100,000,000 of 21/2% Senior Subordinated
Convertible Notes (the Convertible Notes) in a private offering. The Convertible Notes were offered to investors at 100% of their principal amount. The Company incurred approximately $3,750,000 of debt issuance costs, which were being
amortized over the five year term of the Convertible Notes.

In June 2006, the Company completed the redemption of all Convertible
Notes at a redemption price of 100% of principal outstanding, plus interest accrued. Holders of the Notes converted their Notes to shares of the Companys common stock, at a conversion rate of 117.4398 shares of common stock per $1,000
principal amount of the Notes.

In connection with the conversion, the Company wrote off approximately $1,404,000 of unamortized debt issue
costs related to the Notes. Such write off is included in interest expense in the accompanying statements of operations. In addition, debt securities that were pledged to a trustee for the payment of all scheduled interest payments on the Notes were
sold in June 2006. At the time of the sale, the amortized cost of these pledged securities totaled $4,893,000 resulting in a pre-tax loss of approximately $71,000, which is included in other expense in the accompanying statements of operations.

NOTE 8SEGMENT INFORMATION

The Company applies SFAS No. 131, Disclosures about Segments of an Enterprise and Related Information, to determine its operating
segments. Operating segments, as defined by SFAS No. 131, are components of an enterprise for which separate financial information is available and is evaluated regularly by key decision makers in deciding how to allocate resources and in
assessing performance. SFAS No. 131 also requires disclosure about products and services, geographic areas and major customers. The Company currently operates in two operating segmentssoftware and services, for purposes of
SFAS No. 131.

Our senior management reviews financial information to manage the business consistent with the presentation in the
consolidated financial statements, focusing on the revenue and gross profit for each segment. The Company does not allocate research and development, selling, or general and administrative expenses to each segment, as management does not use this
information to measure the performance of the operating segments. Our senior management does not review assets by operating segment. Consequently, such information is not provided herein. Maintenance and services revenue is derived from software
upgrades, technical support, consulting and training. The revenue and gross margins attributable to these segments for the years ended December 31, 2004, 2005 and 2006 are included in the following table (in thousands):

NOTE 9PENSIONS AND OTHER EMPLOYEE BENEFITS

Defined Benefit Pension Plans

The Company has
defined benefit plans (the Plans) covering substantially all of its full-time employees in Japan, Korea, Taiwan and Germany. The Plans typically provide for a lump sum payment upon retirement, which is generally based upon years of
service and compensation. The Plans do not provide continuing salary or benefits upon retirement. As of December 31, 2005 and 2006, there were 259 and 184 active participants, respectively. During the years ended December 31 2005 and 2006,
the Company recognized expense of $1,733,000 and $973,000, respectively.

The Company uses a December 31 measurement date for all of
its pension plans. The fair value of plan assets is determined by market value. The Company expects to contribute approximately $400,000 to its pension plans in 2007, but such amount is subject to change.

As a result of adopting SFAS No. 158, the Company recorded certain adjustments to recognize

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



The adjustment to accumulated other comprehensive income resulted from the recognition of the
transition asset, prior service cost and actuarial gain not included in the net periodic benefit cost during 2006. These amounts will be amortized and recognized as part of the net period benefit cost beginning in 2007.

The Company has plan assets in one of its pension plans only. These plan assets are invested solely in a general account with an insurance company, which
is an investment vehicle that complies with pension fund requirements of the corresponding country. The insurance company manages the funds invested and guarantees a minimum return of 0.75% per annum. The minimum rate of return may be revised
and dividends may also be declared on funds invested in this general account based on current economic conditions and investment performance. Investment in this general account bears minimal risk as the rate of return is fixed and the insurance
company bears risk of loss on the investment of funds that it manages. The Company does not currently have specific investment policies or an investment committee in place to oversee the investment of its pension fund.

There are no contributions paid into an external plan and no asset of the Company identified, segregated or invested specifically to fund the remaining
pension plans. The estimated future benefit payments of these plans are expected to be paid directly by the Company. The following benefit payments, which reflect expected future service, as appropriate, are projected to be paid as follows (in
thousands):

Employee Savings Plan

The Company contributes an amount to a defined contribution plan, covering substantially all North American full-time employees who have completed a specified term of service with the Company. For the years ended
December 31, 2004, 2005, and 2006, contributions charged to expense in connection with this plan were $2,747,000, $2,780,000 and $2,728,000, respectively. The plan has a 401(k) feature to permit voluntary employee contributions, which does
not affect the Companys expenses. The companys contribution vests over a three year period.

Non-Qualified Supplemental Retirement Plan

In 1995, the Company adopted a non-qualified supplemental retirement plan covering certain key employees who have completed a
specified term of service with the Company. For the years ended December 31, 2004, 2005 and 2006, contributions charged to expense in connection with this plan were $115,000, $101,000 and $209,000, respectively. As of December 31, 2005 and
2006, the fair value of plan assets and obligations was $828,000 and $1,082,000, respectively, and are classified in other assets and other long-term liabilities in the accompanying consolidated balance sheets.

NOTE 10 STOCK COMPENSATION

Under the
Companys 2006 Performance Incentive Plan (the 2006 Plan), a maximum of 7,749,596 shares (plus any shares of common stock subject to stock option grants under other Company stock plans in existence where such options expire, are
cancelled or otherwise terminate) of the Companys common stock may be issued under a broad range of potential equity grants including stock options, stock appreciation rights, restricted stock, performance stock, stock units, phantom stock and
dividend equivalents. The purpose of the 2006 Plan is to promote the success of the Company and the interests of its stockholders by providing an additional means for the Company to attract, motivate, retain and reward directors, officers, employees
and other eligible persons through the grant of awards and incentives for high levels of individual performance and improved financial performance of the Company. Equity-based awards are also intended to further align the interests of award
recipients and stockholders.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



The maximum number of shares to be issued or transferred pursuant to awards under the 2006 Plan
equals the sum of: (1) 6,600,000 shares, plus (2) 1,149,596 shares available for additional award grant purposes under the Companys 1998 and 2001 Stock Option Plans (along with the 1991 Stock Option Plan, collectively the
Existing Stock Plans) as of September 25, 2006, the date of the 2006 Annual Meeting of Stockholders, plus (3) any shares of common stock subject to stock option grants under other Company stock plans in existence where such options
expire, are cancelled or otherwise terminate.

Shares issued for option exercises and vested restricted stock, restricted stock unit awards
and performance stock unit awards may be either authorized but unissued shares, or shares of treasury stock acquired in the open market or otherwise.

Stock Options

The Company grants stock options for a fixed number of shares to key employees and non-employee
directors with an exercise price equal to the fair value of the shares at the date of grant. Options are exercisable up to ten years from the date of grant, subject to transfer restrictions and vesting provisions outlined at the grant date.
Generally, options vest ratably in four annual installments. The stock plans provide that vesting may be accelerated in certain events related to changes in control of the Company, unless prior to such change in control the Compensation Committee
determines otherwise. Similarly, the stock plans provide that the Compensation Committee has discretion, subject to certain limits, to modify the terms of outstanding options. No amendment or cancellation and re-grant, subject to permitted
adjustments, shall reduce the per share exercise price to a price less than 100% of the fair market value of the Companys common stock on the option date of the initial option.

In addition to the MSC stock plans, the Company converted outstanding options acquired as part of the AES acquisition in 2001 into fully vested options
to acquire 718,898 shares of the Companys common stock (the AES Options). All such options have an exercise price of $0.10 and were immediately exercisable.

A summary of stock option activity under all the stock option plans for the years ended December 31, 2004, 2005 and 2006 is as follows:

During the fourth quarter of 2006, 1,091,310 restricted stock units were granted to selected employees pursuant to the 2006 Plan, of which 717,760
restricted stock units were time-based grants and 373,550 were performance-based grants. The time-based restricted stock units vest ratably over three anniversary dates ending October 27, 2007, 2008 and 2009. The performance-based restricted
stock units vest equally over three years upon annual achievement of specified performance criteria established by the Compensation Committee of our Board of Directors for each year ending December 31, 2007, 2008 and 2009. Total compensation
cost for these awards were based on the fair market value of the shares at the date of grant, or $13.50 per share. The portion of the total compensation cost related to the performance-based awards is subject to adjustment each quarter based on
managements assessment of the likelihood of achieving the annual performance criteria. In 2006, the Company recognized stock-based compensation of $720,000 related to these awards.

During 2005, in connection with the employment of certain executive officers, the Company granted the right to purchase in aggregate 225,000 shares of
restricted common stock, of which 50,000 shares were granted at the fair value of the shares at the date of grant, 50,000 were granted at $10.00 per share, which was less than the then fair market value of $11.56 per share, 25,000 were granted at
$7.00 per share, which was less than the then fair market value of $11.40 per share, and 100,000 were granted at $11.00 per share, which was less than the then fair market value of $14.30 per share. One executive officer exercised his right to
purchase 50,000 restricted shares of common stock and paid the Company $587,000, while another executive officer exercised his right to purchase 25,000 restricted shares of common stock and paid the Company $175,000. In addition, upon the purchase
of the restricted shares, these executive officers received in aggregate 239,000 restricted stock unit awards which vest over four years. During 2005 and 2006 the Company recognized stock-based compensation charges totaling $1,432,000 and
$1,307,000, respectively, related to these transactions.

As of December 31, 2006, deferred compensation cost related to restricted stock unit awards
totaled $11,594,000, which is expected to be recognized over a weighted average period of 2.8 years.

During 2005, in connection with the
employment of executive officers and other key employees, the Company granted 395,000 performance stock unit awards that vest and are payable in shares if the per share price of MSCs common stock exceeds a pre-established per share for thirty
consecutive trading days on a national stock exchange within two years from the date of grant. The pre-established share price is determined based on the price of common stock at the date of grant. A summary of awards granted is presented below.

On September 5, 2006, the Companys common stock began trading on the NASDAQ stock
exchange thus satisfying the performance condition on its performance stock unit awards pursuant to FAS 123(R). As a result, the Company recognized $1,907,000 in stock-based compensation expense, representing the vested portion of the estimated fair
value through December 31, 2006. The fair value of performance stock unit awards was determined using the Monte Carlo simulation valuation model.

During the year ended December 31, 2005, pursuant to the 2000 Executive Cash or Stock Bonus Plan the Company issued a total of 14,700 shares of its common stock to certain of its officers which was earned in
2004. The amount of stock-based compensation recognized by the Company for the year ended December 31, 2004 totaled $275,000, which is included in selling, general and administrative expenses in the accompanying consolidated statements of
operations. Bonuses earned in 2005 and 2006 are payable in cash and therefore no stock-based compensation has been recognized in 2005 and 2006.

In addition, during 2005 the Company modified the stock options of three departing executives and
in 2004 modified the stock options of one departing executive to extend the life of their options. The modifications were valued using the intrinsic value method pursuant to APB Opinion No. 25 and FIN 44. The Company recorded a non-cash charge
of $3,107,000 in 2005 and $145,000 in 2004 as a result of these modifications, which are included in selling, general and administrative expenses in the accompanying consolidated statement of operations.

The fair value of restricted stock and restricted stock unit awards were determined based on the Companys stock price as of the measurement date.

SAB 107 requires share-based compensation to be classified in the same expense line items as cash compensation. The following table
presents share-based compensation expense for the years ended December 31, 2004, 2005 and 2006, respectively (amounts in thousands):

When applicable, the Company included all tax benefits for deductions resulting from the exercise
of stock options as operating cash flows in its statement of cash flows prior to the adoption of SFAS 123(R). SFAS 123(R) requires the cash flows resulting from the tax benefits for tax deductions in excess of the compensation expense recorded
for those options (excess tax benefits) to be classified as cash from financing activities. To calculate the excess tax benefits available for use in offsetting future tax shortfalls as of the date of implementation, the Company follows the
alternative transition method discussed in FSP SFAS 123(R)-3. There was no material impact to the Companys financial statements upon adoption of the alternative transition method in 2006. The Company recorded excess tax benefits of $1,341,000
during 2006.

Employee Stock Purchase Plan

In September 1996, the Companys Board of Directors adopted the MSC.Software Corporation 1996 Employee Stock Purchase Plan (ESPP), providing a maximum of 1,250,000 shares of the Companys
common stock for purchase by eligible employees. Pursuant to the ESPP, eligible employees were entitled to purchase common stock semi-annually, by means of limited payroll deductions, at a 10% discount from the fair market value of the common stock
as of specific dates. The ESPP is non-compensatory under APB Opinion No. 25 and is intended to provide participating eligible employees an additional incentive to advance the best interests of the Company through ownership of common stock.
Since July 31, 2004, there have been no additional purchases of the Companys stock under the Employee Stock Purchase Plan. In 2004, 191,253 shares were purchased for $1,271,000.

NOTE 11STOCKHOLDERS EQUITY

Preferred Stock

The Companys Articles of Incorporation authorized 10,000,000 shares of
undesignated preferred stock, which may be issued in more than one series. The Board of Directors is authorized to determine or alter the rights, preferences, privileges or restrictions granted to or imposed upon any unissued series of preferred
stock. As of December 2005 and 2006, no preferred shares were issued or outstanding.

Common Stock Repurchase Program

On November 8, 2006, the Board of Directors authorized a stock repurchase program for up to 1,250,000 shares of common stock. Share repurchases will
be made from time to time in the open market, based on stock availability and price. It is anticipated that the repurchases will be made during the next twelve months, although no assurance can be given as to when they will be made or the total
number that will be repurchased. The stock repurchase program has no stated expiration date. Through December 31, 2006, the Company purchased an aggregate of 183,400 shares for $2,581,000, which was recorded in treasury stock on the
consolidated balance sheet.

Shareholder Rights Plan

In October 1998, the Company adopted a Shareholder Rights Plan (the Rights Plan). As part of the Rights Plan, a special type of dividend was declared on the common stock of the Company distributing
these rights to all stockholders of record on October 16, 1998. These rights, which do not have any shareholder rights, including voting or dividend rights, will expire on October 5, 2008, unless earlier redeemed by the Company prior to
expiration at a price of $0.01 per right. The rights automatically transfer with a transfer of common stock until the time they become exercisable, which happens when certain specified events occur. If the rights become exercisable, they entitle the
holders thereof to purchase stock of the Company at a price of $35.00 per share, subject to certain other provisions of the Rights Plan.

NOTE
12COMMITMENTS AND CONTINGENCIES

Leases

The Company leases facilities and equipment under various lease agreements, which range from one to twelve years, which require the following minimum annual rental commitments (in thousands):



|                          |  |   |

|                          |  |   |       

For the years ended December 31, 2004, 2005 and 2006, the rental cost for various facilities
and equipment under operating leases was $16,484,000, $16,615,000 and $16,910,000, respectively. Although the above table reflects the companys obligation on leases until the end of its term, management expects that, in the normal course of
business, most leases will be renewed or replaced by others.

The Company subleases all or part of some of its facilities to third parties. In 2004, 2005 and 2006,
we recognized sublease income of $1,126,000, $1,129,000 and $2,111,000, respectively, which is included in our selling, general and administrative expenses. Annual minimum rental commitments on these subleases are as follows (in thousands):

Litigation

We are subject to various claims and legal proceedings that arise in the ordinary course of our business, including claims and legal proceedings that have been asserted against us by former employees. The Company is
vigorously defending these claims, and believes that it has adequately reserved for potential costs to the Company resulting from these matters, which are not considered material as of December 31, 2006. No assurance can be given, however, that
the ultimate outcome of these claims will not have a material adverse effect on the Companys financial condition or results of operations.

On August 10, 2006, we settled an action by a former senior vice president alleging both employment-related claims as well as claims for breach of his stock option agreement. The amount of the settlement paid in August 2006 was accrued
as of June 30, 2006.

The Company is periodically audited by various taxing authorities in the United States of America and in other
countries in which the Company does business. In the opinion of management, these matters will not have a material adverse effect on the Companys consolidated balance sheet, statements of operations or liquidity.

On November 16, 2006, the SEC notified the Company that it has terminated its investigation that has been underway since April 2005 in connection
with matters related to the restatement of financial statements for the period subsequent to December 31, 2000. No enforcement action was recommended as a result of this investigation.

Indemnifications

The Company indemnifies its
software customers against claims that software or documentation purchased from the Company infringes upon a copyright, patent or the proprietary rights of others. In the event of such a claim, the Company agrees to obtain the rights for continued
use of the software for the customer, to replace or modify the software or documentation to avoid such claim or to provide a credit to the customer for the unused portion of the software license. Due to the nature of this indemnification and the
various options in which the Company can satisfy the indemnification, it is not possible to calculate the maximum potential amount of future payments that may be required.

As permitted under Delaware law, the Company is authorized to provide for indemnification of its officers and directors for certain events or occurrences
while the officer or director is, or was, serving at the Companys request in such capacity. The term of the indemnification period is for the officers or directors term in such capacity. The maximum potential amount of future
payments we could be required to make for such indemnification is the fullest extent permitted by law; however, the Company has a director and officer insurance policy that limits the Companys exposure and enables recovery of a portion of any
future amounts paid in certain circumstances. As a result of the insurance policy coverage, the Company believes the estimated fair value of these indemnifications is minimal.

In connection with the issuance of the Convertible Notes, the Company agreed to indemnify the initial purchasers of the Convertible Notes against certain
liabilities, including liabilities under the Securities Act, or to contribute to payments the initial purchasers may be required to make in respect of those liabilities. The Company believes the estimated fair value of this indemnification is
minimal. Accordingly, there are no liabilities recorded for these types of liabilities as of December 31, 2004, 2005 and 2006.

The Company warrants that its software products will perform in all material respects in accordance
with standard published specifications in effect at the time of delivery of the licensed products to the customer for 90 days. If necessary, the Company would provide for the estimated cost of product warranties based on specific warranty
claims and claim history. However, the Company has not incurred significant expense under its product warranties. As a result, the Company believes the estimated fair value on these agreements is minimal. Accordingly, there are no liabilities
recorded for these agreements as of December 31, 2004, 2005 and 2006.

Severance Compensation Agreements

The Company has entered into Severance Compensation Agreements with twenty-five employees. These Agreements, subject to annual review by the
Companys Board of Directors, are automatically extended in one year increments unless canceled by the Company 60 days prior to the end of the calendar year. These Agreements provide for specified benefits in the event of a change in control,
as defined in the Agreements. For Messrs. Weyand, Wienkoop, Laskey and Mongelluzzo these agreements provide 2.5 times annual salary and bonus in the event of termination by the Company for other then Cause (as defined) or by the executive for other
then Good Reason (as defined) within two years following a Change in Control (as defined). In addition, these individuals would receive a gross-up-payment for any excise tax imposed by Section 4999 of the Internal Revenue Code. Four
other executives are covered by a similar agreement but would be entitled to a 2.0 multiple and are not subject to a grossup-payment. Seventeen other employees are subject to a similar agreement but would be entitled to a 1.0 multiple and also
are not subject to a gross-up-payment. The agreements also provide for additional benefits including continued health care benefits. In accordance with his Employment Agreement Mr. Weyand would be entitled to one times his annual salary if
terminated for other then cause (irrespective of a change in control).

The following table shows the common stock equivalents that were outstanding as of December 31, 2004, 2005 and 2006, but were not included in the computation of diluted earnings (loss) per share because the common stock
equivalents exercise price was greater than the average market price of the common shares for the period presented and, therefore, the effect would be anti-dilutive, or the effect of the conversion would otherwise be anti-dilutive:

NOTE
15DISCONTINUED OPERATIONS AND SALE OF LONG-LIVED ASSETS

ESTECH Corporation

In the fourth quarter of 2005, the Company approved a plan to sell its wholly owned Japanese service subsidiary, ESTECH Corporation (ESTECH).
Accordingly, ESTECH has been presented as a discontinued operation within the consolidated financial statements in accordance with SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets. ESTECH was
acquired in 2002 as part of the MDI acquisition and provides expert technical services, primarily in structural dynamics, motion, vibration and acoustics to customers primarily in the automotive and precision electronics industries.

On January 31, 2006, the Company entered into a Stock Sale and Purchase Agreement to sell its wholly owned Japanese service subsidiary, ESTECH
Corporation, to Information Services InternationalDentsu, Ltd. (ISID), a channel partner of the Company. On March 18, 2006, the sale was consummated and the Company received 1.2 billion Yen, or approximately $10.2 million, resulting in an
estimated loss of $1,110,000, which was accrued as of December 31, 2005 and recorded as a loss from disposal of discontinued operations.

The results of the discontinued operations of ESTECH included in the accompanying consolidated statements of operations for the years ended December 31, 2004, 2005 and 2006 were as follows (in thousands):

NOTE 17SUBSEQUENT EVENT

On January 17, 2007, the Board of Directors of MSC.Software Corporation approved the implementation of a cost reduction program that includes a reduction of its current workforce by 85 employees, or approximately
7%, and facility closings and consolidations. The cost reduction program was deemed necessary to better align the Companys global operating costs with its new enterprise sales strategy in an effort to compete aggressively in all markets and to
improve operating profit. The Company estimates that total costs related to the cost reduction program will be between $6.0 million and $8.0 million, which includes a charge for severance and termination benefits of between $5.0 million and $6.5
million and charges related to facility closings and consolidations of between $1.0 million and $1.5 million. The Company expects such charges will be incurred and recognized in the first and second quarters of 2007.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors

MSC.Software Corporation

Santa Ana, CA

We have audited the accompanying consolidated
balance sheets of MSC.Software Corporation and subsidiaries (the Company) as of December 31, 2006 and 2005, and the related consolidated statements of operations, shareholders equity and comprehensive income (loss), and cash
flows for each of the three years in the period ended December 31, 2006. Our audits also included the financial statement schedule listed in the Index at Item 15. These financial statements and the financial statement schedule are the
responsibility of the Companys management. Our responsibility is to express an opinion on the financial statements and financial statement schedule 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 MSC.Software Corporation and subsidiaries at December 31, 2006 and 2005, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2006, in conformity with
accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, present fairly, in
all material respects, the information set forth therein.

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 December 31, 2006, based on the criteria established in Internal ControlIntegrated Framework issued
by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 1, 2007 expressed an unqualified opinion on managements assessment of the effectiveness of the Companys internal control over

Evaluation of Disclosure Controls and
Procedures

We evaluated the design and operating effectiveness of our disclosure controls and procedures as of December 31, 2006,
under the supervision and with the participation of our management, pursuant to Rule 13a-15(b) of the Securities Exchange Act of 1934, as amended (the Securities Exchange Act). Based on this evaluation, our Chief Executive Officer and
Chief Financial Officer concluded that our disclosure controls and procedures, as defined in Rule 13a-15(e), were effective in ensuring that information required to be disclosed in our periodic SEC filings is recorded, processed, summarized, and
reported within the time periods specified in the SECs rules and regulations, and is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely discussions
regarding required disclosures.

Managements Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining an adequate system of internal control over financial reporting, pursuant to Rule 13a-15(c) of
the Securities Exchange Act. This system is intended to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles
generally accepted in the United States (GAAP). A companys internal control over financial reporting includes policies and procedures that: (i) pertain to the maintenance of records that, in reasonable detail, accurately and
fairly reflect the transactions and dispositions of the assets of the company, (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that
receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company, and (iii) 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.

##### Table of Contents

As part of our compliance efforts relative to Section 404 of the Sarbanes-Oxley Act of 2002, our
management assessed the effectiveness of our internal control over financial reporting as of December 31, 2006. In making this assessment, management used the criteria set forth in the Internal Control  Integrated Framework by the
Committee of Sponsoring Organizations of the Treadway Commission (COSO). The COSO framework summarizes each of the components of a companys internal control system, including the: (i) control environment, (ii) risk
assessment, (iii) information and communication, and (iv) monitoring (collectively, the entity-level controls), as well as a companys control activities (process-level controls). In addition to utilizing
substantial internal resources, management also engaged an outside consulting firm to assist in various aspects of its evaluation and compliance efforts. Based on managements evaluation under the framework inInternal Control 
Integrated Framework, management concluded that the Companys internal control over financial reporting was effective as of December 31, 2006.

Our independent registered public accounting firm has issued an audit report on our assessment of the Companys internal control over financial reporting. This report appears under the Report of Independent
Public Accounting Firm which is included below.

A material weakness is defined as a significant deficiency or combination of
significant deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected. A significant deficiency is defined as a control
deficiency, or combination of control deficiencies, that adversely affects the Companys ability to initiate, authorize, record, process, or report external financial data reliably in accordance with generally accepted accounting principles
such that there is more than a remote likelihood that a misstatement of the Companys annual or interim financial statements that is more than inconsequential will not be prevented or detected.

Changes in Internal Control over Financial Reporting

Management undertook significant efforts during 2006 to establish a framework to improve internal controls over financial reporting, particularly as they related to the material weaknesses previously disclosed in our 2005 Annual Report on
Form 10-K. We committed considerable resources to the design, implementation, documentation, and testing of our internal controls. Additional efforts were required to remediate and re-test certain internal control deficiencies. Our management
believes that these efforts have improved our internal control over financial reporting.

During 2006, we added staff with technical
accounting experience to increase the level of review over the Companys accounting, disclosure, and compliance with accounting principles generally accepted in the United States of America. In addition, we undertook initiatives to improve our
communication, monitoring, risk assessment and processes and procedures, including upgrading our financial and management information systems.

Inherent
Limitation on the Effectiveness of Internal Controls

The effectiveness of any system of internal control over financial reporting is
subject to inherent limitations, including the exercise of judgment in designing, implementing, operating, and evaluating the controls and procedures, and the inability to eliminate misconduct completely. Accordingly, any system of internal control
over financial reporting can only provide reasonable, not absolute assurances. In addition, 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. We intend to continue to monitor and upgrade our internal controls as necessary or appropriate for our business, but cannot assure you that such
improvements will be sufficient to provide us with effective internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors

MSC.Software Corporation

Santa Ana, CA

We have audited managements assessment, included in the accompanying Managements Report on Internal Control Over Financial Reporting that
MSC.Software Corporation and subsidiaries (the Company) maintained effective internal control over financial reporting as of December 31, 2006, based on criteria established in Internal ControlIntegrated Frameworkissued 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.

In our opinion, managements assessment that the Company maintained effective internal control over
financial reporting as of December 31, 2006, is fairly stated, in all material respects, based on the criteria established in Internal ControlIntegrated Frameworkissued by the Committee of Sponsoring Organizations of the Treadway
Commission. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2006, based on the criteria established in Internal ControlIntegrated
Frameworkissued 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 and financial statement schedule as of and for the year ended December 31, 2006 of the Company and our report dated March 1,
2007 expressed an unqualified opinion on those financial statements and financial statement schedule and included an explanatory paragraph regarding the Companys adoption of a.) Statement of Financial Accounting Standards No. 123(R),
Share-Based Payment,and b.) Statement of Financial Accounting Standards No. 158, Employers Accounting for Defined Benefit Pension and Other Postretirement Plans  an amendment of FASB Statement No. 87, 88, 106 and
132(R).
