CHORDIANT TO RESTATE HISTORICAL FINANCIAL STATEMENTS RELATED TO STOCK-BASED COMPENSATION

APPOINTS NEW CHAIRMAN OF THE BOARD

CUPERTINO, California - November 30, 2006 -- Chordiant Software, Inc. (Nasdaq: CHRD), the leading provider of Customer Experience (Cx™) software and services, announced today that it will restate its historical financial statements to correct errors related to accounting for stock-based compensation expense.

As previously disclosed on July 24, 2006, the audit committee of Chordiant’s board of directors began an independent review of the Company’s historical stock option grant practices and related accounting. The audit committee’s review was initiated at the suggestion of management subsequent to a review they had conducted. The audit committee has been assisted by independent legal counsel and independent forensic accounting consultants. The review has focused on the processes used to establish the option exercise price, the processes used to obtain required approvals of stock option grants and the related measurement dates used for financial reporting purposes. The audit committee is continuing its review of certain exercises of stock options during 2001 and 2002 by former senior officers of Chordiant.

During the course of the review, the audit committee reached the conclusion that pursuant to the requirements of Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (APB 25), the correct measurement dates for certain stock option grants made by Chordiant during the 2000 to 2006 fiscal years differ from the measurement dates previously used to account for such option grants. Although the review is not completed, on November 26, 2006, Chordiant’s board of directors concluded that the Company should restate its historical financial statements for the years ended December 31, 2001, 2002 and 2003, the nine-month period ended September 30, 2004, the fiscal year ended September 30, 2005, and the quarters ended December 31, 2005 and March 31, 2006, to record additional non-cash, stock-based compensation expense related to past stock option grants having incorrect measurement dates and other administrative inconsistencies. Based on the findings to date, the non-cash stock-based compensation expense to the financial statements related to those periods is expected to be approximately $8 million. The Company is continuing its review of factors that may have led to incorrect measurement dates. The majority of the errors having significant financial statement impact relate to options that were granted between late 2000 and mid 2003 and generally vested over periods ranging from one to four years if not canceled or forfeited by the recipient.

Accordingly, the financial statements and all earnings press releases and similar communications issued by the Company related to those periods should not be relied upon pending completion of the restatements. The amount of additional non-cash stock-based compensation expense to be recorded in any specific period or future period and the resulting tax and accounting impact have not been determined.

Chordiant has discussed the above matters with BDO Seidman, LLP, the Company’s independent registered public accounting firm, and PricewaterhouseCoopers LLP, the Company’s predecessor independent registered public accounting firm. The audited financial statements cannot be filed until both firms have completed their respective reviews.

Chordiant expects that expenses arising from the investigation, the restatement and related activities, which will be recorded in the periods incurred, will be significant. The cost of the investigation and related accounting cost incurred through October 31, 2006 was approximately $1.5 million.

Chordiant also announced today the resignation and retirement of its Chairman of the Board and Chief Strategy Officer, Samuel T. Spadafora, effective immediately. After a lengthy career in the technology industry, including eight years at Chordiant, Mr. Spadafora is retiring from full time employment.

Chordiant further announced that its Board of Directors has appointed the Company’s President and Chief Executive Officer, Steven R. Springsteel, as Chairman of its Board of Directors.

Mr. Spadafora served as Chairman of Chordiant’s Board of Directors since November 1999. In 2004, the Board appointed him to the position of Chief Strategy Officer and head of the corporate strategy team. Mr. Spadafora served as Chief Executive Officer and a Director of Chordiant from June 1998 to January 2002. From June 1998 until October 2000, he was also Chordiant's President.

“During the eight years he has been with Chordiant, Sam has made significant contributions to the direction and growth of the Company,” said Mr. Springsteel. “His leadership was instrumental in growing the Company from a start-up, through its IPO in 2000 to approximately a $100 million revenue run rate today. Under his guidance Chordiant has become a dominant leader in retail financial services, insurance and telecommunications. Today, Chordiant is growing with a winning strategy, strong business model and great customer traction,” Mr. Springsteel said. “On behalf of Chordiant, I would like to thank Sam for his many contributions,” he added.
