JDA has earned their confidence based upon the deal’s prospects and our proven ability to generate cash from operations.

3. What kind of company is Thoma Cressey?

Private equity firm Thoma Cressey Equity Partners (TCEP) has been investing in industry-leading businesses for nearly 30 years. Since its origins in 1980, TCEP has invested more than $2 billion in equity through a series of eight private equity funds.

A major part of TCEP’s investment focus is on the Software sector. Over the past five years, the firm has invested in software companies with more than $350 million in combined earnings before interest, taxes, depreciation and amortization (EBITDA), and in transactions with aggregate values totaling nearly $2 billion. Through these investments, TCEP has emerged as a leading private equity investor in the Enterprise Software and Application Software industries.

In conjunction with the management teams of TCEP’s software portfolio companies, the firm looks to add value to its portfolio companies through a combination of operational improvements and complementary add-on acquisitions. As such, TCEP seeks opportunities with characteristics that make the execution of this strategy possible. Specifically, the firm looks for industry leading businesses with seasoned management teams, a high level of recurring revenues and a mission-critical product in industries that lend themselves to consolidation. In addition to its focus on Enterprise and Application Software, TCEP’s other areas of interest include the Financial Technology, Systems Management and Technical Software industries.

operating metrics while providing the market with a real alternative to the generalist horizontal providers.

This investment will close concurrent with, and is contingent upon, the closing of the Manugistics transaction.

Bravo, who has led software industry investments totaling approximately $300 million in equity capital over the past three years, will join JDA’s Board of Directors. Bravo formerly served as Chairman of Prophet 21, Inc. and currently serves as a Director of Made2Manage Systems, Inc and Datatel, Inc.

Plans include:

• Leverage latest advanced technologies to deliver a world-class combined offering without a major rewrite of software code.

• Extending database support for Manugistics products to include SQL Server 2005.

We appreciate everyone operating in a “business as usual” mode while managing your daily priorities. In particular, we ask that you remain focused on the needs of our customers and prospects.

2. Can another company bid for Manugistics?

JDA signed a binding, definitive merger agreement with Manugistics on April 24, 2006. There is always the chance that another company may make an offer while the acquisition is still pending and that Manugistics’ Board may decide not to conclude the transaction with JDA or the stockholders of Manugistics decide not to approve the transaction.

If either Manugistics or JDA terminates the transaction under certain circumstances, Manugistics may be required to pay JDA a transaction termination fee. If a fee is payable, such fee would either be $9.75 million or $4.875 million depending on the circumstances of the termination.

SECTION 5:Update Specifically for Employees

1. How will this acquisition benefit employees?

JDA values the deep intellectual capital of the two companies’ employees. JDA and Manugistics executives look forward to bringing together the industry’s best minds in a stimulating work environment to ensure the ongoing innovation and enhancement to the industry’s most powerful combined solution suite. The combined company will ...

• Provide employees with the opportunity to work for a larger company with significantly increased earnings capacity and the financial wherewithal to maintain a competitive compensation and benefits environment.

• Create expanded opportunities throughout the company, and in particular two areas targeted for immediate investment: Customer Support Services (CSS) and New Product Development.

• Establish a center of industry excellence that enables employees to open new doors for career growth by taking on leadership roles and expanding skills across the entire supply and demand chain.

• Provide opportunity to gain new expertise or maximize current abilities with two recognized leading technologies: Java and .NET.

2. What can employees expect until the acquisition is closed (approx. July 06)?

JDA and Manugistics senior executives thank employees across both companies for their support and positive outlook for the pending acquisition. Until the pending acquisition receives all of the necessary approvals and is closed, which could be in two to three months, your work should be performed “business as usual.” All employees should stay focused on their deadlines, customer commitments and daily responsibilities, under normal management.

After closing, JDA is confident that employees in the combined company will work diligently for a smooth transition that positions us for success.

3. Which Manugistics executives will join JDA’s executive leadership team?

JDA has an established practice of incorporating management from its nine previous acquisitions into its management team. While it is expected that Manugistics CEO Joe Cowan will pursue other opportunities after the acquisition closes, JDA expects to welcome a significant percentage of Manugistics’ current management team to roles in the newly combined company. JDA is pleased to note that several members of Manugistics’ management team have accepted offers from JDA and will be joining JDA’s current management team after the acquisition is final.

4. Where will the Corporate Headquarters be located?

The combined company will be headquartered in Scottsdale, Arizona at JDA’s current world headquarters. JDA plans to continue operating Manugistics’ corporate office in Rockville, Maryland.

In nearly every city that Manugistics has a branch office; JDA also has an office operating. For example, there are both a JDA and a Manugistics branch office operating in these cities and/or geographies: Chicago, Illinois; Atlanta, Georgia; Northern California; Sydney, NSW, Australia; Tokyo, Japan; Shanghai, China; Sao Paulo, Brazil; Paris, France; Spain and United Kingdom.

To reduce costs while ensuring the best ongoing service to customers, JDA expects to combine several of these branch operations in the United States and internationally after the deal closes. JDA will give significant notice to employees who are based in these offices.

5. What are JDA’s plans for Manugistics’ operations in India?

With operations and offices on every major continent, JDA welcomes the addition of an office in India, a major global economic retail market that has grown an average of nine percent annually over the past five years.

JDA’s senior management has visited this office during the due diligence phase of the pending acquisition. JDA believes that it can leverage Manugistics’ multi-year presence, experience and capabilities in India to optimize its global cost of development and delivery of solutions with an ideal mix of resources. This office will report into product development.
