Information regarding these participants is available in each company’s annual report and proxy statement and will be included in the registration statement and joint prospectus proxy.

I’ll now turn the call over to Jim, the ANSYS President and CEO. Jim

Jim Cashman: OK. Well thanks Maria and thank all of you for joining us on what we think is a particularly noteworthy occasion. So again, to repeat, I’m very pleased to announce that ANSYS has signed a definitive merger agreement to acquire Ansoft Corporation for approximately $416 million in cash and 11.1 million shares of Ansoft stock or approximately 832 million, creating the leading global provider of best in class simulation capabilities with combined trailing 12 month revenues of 485 million.

We’re very excited about this strategic combination as it creates value and opportunity for all of our major constituency groups, customers, employees, partners and stock holders of both companies. We expect that this transaction will be modestly accretive to ANSYS non-GAAP earnings in the first full year of combined operations.

The addition of Ansoft’s complimentary technology will enable to continue us on the journey that we’ve been talking about for over 10 years now, by expanding the depth and the breathe of simulation capabilities and it plays into expanding our customer interaction and support activities.

Now as I mentioned earlier and I think Maria also, joining us for the call is Nick Csendes, the President and CEO of Ansoft. Thanks Nick for joining us and for all of your efforts and support in helping us bring these two great ((inaudible)) based companies together.

So with that in mind let’s continue to the slide deck. Taking a quick look we’ll go to slide number four titled “Transaction Summary.” Under the terms of the agreement, Ansoft stock holders will

receive $16.25 in cash and .4319 shares of ANSYS common stock for each share of Ansoft. Based upon the 10 day trailing average closing price of ANSYS common stock, the implied value is $32.50 per Ansoft share, representing and aggregate transaction of 832 million or approximately 416 million in cash and 11.1 shares of Ansoft stock that will be used to fund the transaction.

We are currently expecting to close the deal in the second quarter of 2008, of course subject to the customary closing conditions, regulatory approvals and Ansoft stock holder approval. Upon completion of the transaction, Ansoft stock holders will own approximately 12 percent of the combined company on pro forma basis.

Also at this time I want to mention that following the closing of the transaction Doctor Zoltan Cendes, Founder and Chairman of Ansoft will join the ANSYS board of directors. We also have the one important factor working in our favor that should make integration a little less challenging then some of the other transactions that we’ve done in the past. In both Ansoft – ANSYS and Ansoft headquarters are here in the Pittsburgh area within 15 or so miles of each other; so critical in the face to face meeting and communications particularly as part of the integration efforts so that it can easily accommodate those.

Now if we look at slide five, just “Company Highlights” is the title, we’re enthused about this transaction for a number of reasons; most notably the way in which our software and maintenance offerings compliment one another but also the relative consistency of the company’s visions and cultures. Both companies have been singularly devoted to excellence and engineering simulation for many, many years. Both have been serving abroad global industrial base and providing quality software products, maintenance and service and both, most importantly, are committed and passionate about what we do and as a result have run viable strong businesses.

Now on slide six, for 2007 ANSYS reported record annual non-GAAP revenues of 387 million and for the trailing 12 months ended January 31st, 2008 Ansoft reported revenues of 98 million. I just want to take a quick moment to those of you who may not know the Ansoft story to point out that while ANSYS is on a calendar year end; Ansoft has a April 30th year end. So they’re currently in the process of finishing out their 2008 fiscal year.

Now as you can see from the two charts on slide six, they’re remarkably similar in a number of important ways, the most notable being consistent long term double digit growth on the top line that translates into strong operating margins and earnings growth. These similarities will serve as a solid foundation for the combined entity as we move ahead.

And actually with this I’d like to turn the call over to Nick Csendes to provide some of his own comments about the transaction as well as to give you a brief overview of the Ansoft business. Nick …

Nick Csendes: Thank you, Jim. Before we continue with the slide deck, I would just like to add a few personal comments about today’s announcement.

This is a very exciting day for the employees, customers and stockholders of Ansoft.

As the engineering simulation software space continues it’s evolution it is more critical then ever to have the size, scope and scale that will enable us as a combined company to continue to invest in innovation that ultimately results in a very real and measurable benefit to our customers in the form of greater productivity, higher efficiency and lower cost.

Both ANSYS and Ansoft have long standing reputations for consistent performance and solid operating results. By combing our respected companies we are confident that we can continue to drive operational performance with the ultimate goal of furthering customer and employee satisfaction while also focusing on long term value creation for stockholders.

Financially the two companies have trailing annual revenues of $485 million and the combined enterprise will have a strong balance sheet and cash flows that should serve as a solid foundation to build from. Ansoft’s stockholders will be 12 percent owners of the combined company and will have the opportunity to participate in the upside that we believe this transaction can create. That is why I and my brother ((inaudible)) are solidly behind this strategic business combination and why the Ansoft board of directors unanimously supports it.

We look forward to working with Jim and the ANSYS team to complete this transaction and we look forward to the years ahead to realized value of this merger for the benefit of our respective stakeholders. So I will now move on to slide seven and go through a high level overview of Ansoft.

We believe that Ansoft has world leading technology and high performance EDA stimulation software especially in electromagnetics. Our technology has been developed over the past 25 years and our products are used by over 10,000 electrical engineers at over 2,000 companies worldwide to design state of the art technology products. Products designed using our software includes cell phones, networking products, satellite communication systems, integrated circuits and circuit boards, electronic sensors and motors and many other types of products.

Our customer base is diversified across multiple geography’s and industries. We have a strong financial profile and have consistently grown both our top and bottom lines over the past five years. Our top line grew at a double digit rate and we expanded our operating margins at an even greater rate. Our operating margins for the 12 months ending January 31st of this year was approximately 37 percent.

In terms of our products they fall primarily into two categories, high performance electronic software and electromechanical software. Customers use our high performance electronic software products in the design and manufacturing of ((inaudible)) systems, high speed interconnects, millimeter wave IC’s, radio frequency IC’s, RVID tags and WiMAX IC’s amongst others.

Electromechanical software is used in the design of electromechanical components including solenoids and transformers, power electronics and drives, automotive systems as well as many aspects of the aerospace industry.

So let me now turn the call back over to Jim.

Jim Cashman: OK. Thanks Nick. So let – actually I’ll ask you to move on to slide eight and we’ll spend a few – a few minutes on the strategic rational. That’s the title for slide eight. And the good news, for those of you who have been long term followers of ANSYS, the fundamentals of the story for the Ansoft acquisition should sound very familiar to what you’ve heard us say in past acquisitions.

This transaction further enhances our vision of simulation driven product development through the addition of world class EDA technology that extends the ANSYS multiphysics strategy. The combination will give us a unique opportunity to add complimentary physics that address the convergence of the mechanical engineering and the electrical engineering product design and development.

It’ll take simulation to yet a new level, a level that our customers are constantly needing and demanding. Both ANSYS and Ansoft have been committed to technology advancement over the years and the combined entity will continue to invest in the range of 15 percent of revenues across 21 development centers on three continents allowing us to bring innovation closer to our customer wherever they are in the globe.

So now on page nine, being close to our customers has been a fundamental passion for both companies historically. And I’m encouraged on how complimentary our direct presences are. And when you couple these with the significant indirect channels we think we have a powerful capability to bring this technology to broader applications and to better serve our customers.

As I’ve mentioned a number of times, and this is a critical aspect as it relates to our go forward plans, the company cultures are very similar in their commitment to serving customers, maintaining long term relationships with employees and partners and in general treating their commitments very seriously.

To net it all out, we’re looking at two companies that share a vision, a passion for technology and base all of this on a solid business model that allows sustainable growth. The revenue growth rates and the solid operating margins of both companies’ couple with a strong basis of recurring revenues allow for good visibility and the ability to manage the business going forward.

So if we turn now to slide 10, many of you who are familiar with ANSYS have seen this slide in a number of different manifestations. It actually captures the essence of our journey over the last 10 plus years. And as you can see, the acquisition of Ansoft is yet another milestone that moves us further along the path that we have consistently outlined for ourselves. It truly fits hand and glove with the vision.

The ability to simulate complete systems in the environments that they’ll operate in through our unique approach to multiphysics. This combination also continues to better position us to provide the solutions our customers need to solve their increasing problems and demands.

Now on slide 11, kind of an interesting one. A few slides back ago I think I talked about the convergence we’re seeing between the worlds of mechanical and electrical engineers. So if you look at slide 11, this is a great visual that we borrowed from Ansoft. And it kind of helps depict this convergence.

We all know the global challenges around oil and gas consumption are not only real but they’re consuming greater and greater amounts of resources to address the problems relative to future alternatives. In this slide you can see the example of an Humvee vehicle. Now usually this denotes in most of our minds a beefy rugged mechanical structure that’s subjected to harsh environments and rough duty cycles.

Upon close inspection of this chart though, you might notice that there are also a series of even more sophisticated mechanical design issues but also the identification of a series of equally sophisticated electronic ones, those related to control systems, monitoring devices, power distribution, motors, generators and many others.

This is the emerging world of today where true virtual prototyping must extend to the entirety of the product to be able to guide the ultimate success of that product. You know as a further example, just consider how hybrid drives and fuel cells and active safety systems have grabbed the headlines in recent times.

On slide 12, you can actually see that – well that’s just one example. We are broad customer presence as well as an even more diversified range of customers. This broad diversity solid install base and, more importantly, our open environment will invite partner, channel, academic and commercial customer relationships that help us build for the long term. We know we have to be an open, flexible system to fit into a wide range capabilities if we want to fit into our customer environments.

Now slide 13, this’ll give you a little snapshot as you can see on this slide. We’ll continue to have a very strong combined global presence and the geographic revenue diversification that will

continue to be part of the strength of our ongoing business model. In line with the historical ANSYS model, North America will make up around 37 percent on a combined basis. Europe about 36 percent and GIA, now slightly higher at around 27 percent. Combined, we have the scale and the reach to be near to and to grow with our customers no matter where they’re located in the world.

We think that really, this combination – and, I’ll refer you to slide 14 titled Value for All Key Constituencies. We think that the value – the combination of ANSYS and Ansoft is truly a win, win scenario for all of our key constituencies. For customers, we’ll provide trusted, viable, long term partner with a commitment to engineering simulation which has been demonstrated over 37 years and an ability to deliver world class, open and flexible solutions to solve their critical problems.

For employees, this is a chance to maintain their long-standing dedication and focus on engineering with an even larger company that can provide critical mass, long term stability and enriched career opportunities.

And for the stockholders of both ANSYS and Ansoft, this deal is positive not only for the long term but, as I mentioned before, is expected to be modestly accretive to non GAAP earnings in the first year of combined operations.

So on slide 15, titled Key Financial Metrics. As you can see, those metrics mostly speak for themselves. But, let me say that overall, we expect strong revenue growth and, strong revenue visibility, with just under $150 million in combined deferred revenues. When combined with our strong cash flow generation to support the pay down of the debt and the strong growth in operating profit margins, we’re truly excited about the opportunity this combination affords.

Nick, is there anything you’d like to add?

Nick Csendes: Yes, thanks Jim. I would actually like to reinforce what you said which is that I think that it is a combination of two companies that will definitely bring customers what they have been and, will continue to be asking for which is the ability to do their complete design process from structural influence to electronics to sending it to their PLM systems without a glitch. I think this combination will definitely push that visions further.

Jim Cashman: OK. So, thanks Nick. So, now, let me turn it over to Maria for a few comments relative to the financial benefits. Maria?

Maria Shields: OK. Thanks everyone and I’ll refer you to slide 16 at this point.

We’re very excited about the opportunity on both the revenue and cost savings front. From a revenue point of view, both companies have great installed bases that should serve as a solid platform for not only cross selling but, equally as important, up selling. The further expansion of the breadth and depth of capabilities that the Ansoft portfolio bring to ANSYS should also enable us to target an even larger potential user base.

On the cost savings side of the equation, very similar to what we just experienced with the integration of the Fluent acquisition, we seen immediate ability to optimize as well as re-deploy R and D resources based upon the future direction of the combined companies. We will also identify and target opportunities for efficiencies in the area of G and A, sales and services and finally, we will target, over time, the elimination of redundant infrastructures and facilities, where it’s possible. Because as we’ve learned through all the acquisitions that we’ve done over the years, not only can we experience cost savings but, more importantly, we gain an upside from combining the teams into one location where we have overlaps that better enables them to really work and function as a team in their respective locations. Jim?

Jim Cashman: Yes. Thanks, Maria. Let’s move on to slide 17. So moving on to integration and from an integration perspective we will, as we have done with all of our previous acquisitions, form a team made up of key leaders from both ANSYS and Ansoft whose mission it will be to work to bring these two great companies together. Now, while there will always be challenges along the way, we have a shared vision for execution and we foresee minimal disruption to either business as a result of this deal. As long as we keep the best interest of our customers, employees and, the stockholders at the core of our thinking, we should be able to drive the upside that exists from merging ANSYS and Ansoft together. I’d like to remind everyone that while we can begin high level integration planning, we can not begin to implement until the transaction is closed and we are operating as combined entity.

With – so, in slide 18, basically, in summary, I’ll just add that first, ANSYS has always been committed to a broad range of capabilities supporting the vision of simulation driven product development. As you can see, there are many parallels but, that’s only why this deal makes strategic sense, which we’ve tried to summarize here.

The complimentary capabilities help us achieve our vision more quickly. And the diversity of the customer base allows us the opportunity to provide value in so many new ways, tapping into the historical Ansoft strengths in terms of vertical industry expertise, loyal install base and, expanded channel capabilities. This combination literally allows us to take simulation to an even higher level.

And in closing, I’d like to thank the ANSYS base of loyal customers who continue to grow with us in new ways everyday. The expanding array of industry partners and the employees of the current future ANSYS team. They’re the reason for the success that we’ve seen over the years. And I’m personally excited and, proud, to be part of this team. And I look forward to working with
