Filed below is a communication provided to employees of JDA and i2 on January 25, 2010 regarding JDA’s proposed acquisition of i2.


Dear Employee:

We have received a number of questions regarding what will happen to any outstanding stock options and restricted stock units granted to employees upon completion of the acquisition of i2 Technologies, Inc. by JDA Software Group, Inc. Based on the terms of the merger agreement, see below for an explanation of what will happen to your unexercised stock options, both vested and unvested, and your restricted stock units as a result of the merger. The explanation assumes that the merger is effective on January 28, 2010.

Stock Options

The vesting of each outstanding stock option at the effective time of the merger will be accelerated such that, at the time of the merger, all outstanding stock options will be fully vested.

Each outstanding stock option will be converted at the effective time of the merger into the right to receive, as soon as practicable after the effective time of the merger, a combination of JDA common stock and cash having a value equal to the excess, if any, of the Common Stock Merger Consideration on January 27, 2010 over the per share exercise price of such stock option multiplied by the total number of shares of common stock then subject to such stock option. For convenience, we refer to this amount as your “option spread.”

As illustrated in the example below, your option spread will be hypothetically converted into shares of i2 common stock, assuming each i2 share has a value equal to the Common Stock Merger Consideration. Each of these hypothetical i2 shares will then be converted into 0.2562 of a share of JDA common stock (or cash in lieu of any fractional share) and cash in the amount of $12.70 in order to determine the consideration issuable in respect of your options.

The Common Stock Merger Consideration is equal to the JDA closing stock price on January 27, 2010 multiplied by 0.2562, the product of which is added to $12.70.

If the exercise price of an option is equal to or greater than the Common Stock Merger Consideration, then the option will be cancelled at the time of the merger, without payment of any consideration.

As you are aware, on January 20, 2010 both i2 and Morgan Stanley Smith Barney imposed a moratorium on exercises, sales, transfers, or any other type of dispositions within Benefit Access. This will allow all transactions to settle prior to the anticipated acquisition date of January 28, 2010.

At the completion of the merger, you will be entitled to receive the consideration payable for your options without any action on your part and without payment of broker fees. However, required tax withholding will be deducted from the cash portion of your option consideration.

Restricted Stock Units

Except for restricted stock unit grants dated April 20, 2009 or later, each restricted stock unit will vest in full at the effective time of the merger. If you have a restricted stock unit grant dated April 20, 2009 or later, only the tranche that would vest within 1 year of the merger effective date will


vest at the time of the merger. The remaining vesting tranches will be cancelled in accordance with Paragraph 4c of the Restricted Stock Issuance Agreement.

For each vested restricted stock unit, you will be entitled to receive 0.2562 of a share of JDA common stock (or cash in lieu of any fractional share) and cash in the amount of $12.70.

Timing of Payment

As soon as practicable after the merger, you will be entitled to receive your merger consideration. Shares of JDA common stock are expected to be delivered after the merger to an account set up for you at Morgan Stanley Smith Barney. The cash payment will be made through payroll [in the same manner as a bonus payment], however, the total consideration for your options and restricted stock units will be treated in a manner similar to wages with appropriate statutory tax and other withholdings from the cash portion of the consideration.

U.S. Employees

For our U.S. employees, the cash will be processed through Payroll, with withholdings deducted at the appropriate tax rates. Shares of JDA stock will be transferred to an account set up for you at Morgan Stanley Smith Barney.

Non-U.S. Employees

For employees outside the U.S., the gross amount payable in U.S. dollars will be converted to the local currency and processed through the local payroll system with withholdings for all applicable payroll taxes (at statutory rates). If the receipt of JDA common stock by citizens of a country is not permitted by applicable law, those shares will be converted into cash, and the entire option or restricted stock unit consideration will be payable in cash.

Currently we anticipate that special payrolls will be run so that payments to all holders of employee stock options and restricted stock units will be received as quickly as possible after the merger close.

Trading Restrictions

We anticipate that there will be no trading restriction for all i2’ers (except Executives and the Board of Directors), as JDA earnings will already be released to the public. Please note, however, that you should not trade your shares if you have material inside information. Insider information is defined as “material,” or significant information, either positive or negative, that has not been publicly disseminated. Information is material if a potential or existing investor might consider it relevant in making a decision regarding investing in the Company’s stock.

Following are examples of exactly how the number of JDA shares and amount of cash issuable in the merger will be calculated for both options and restricted stock units.
