FOR IMMEDIATE RELEASE


             KROLL INC. TO ACQUIRE ONTRACK DATA INTERNATIONAL, INC.

            Acquisition Will Propel Kroll to a Leadership Position in
     Data Recovery, Electronic Discovery and Computer Forensics Marketplace

         Transaction Expected to be Immediately Accretive to Kroll's EPS


NEW YORK, April 2, 2002 -- Kroll Inc. (Nasdaq: KROL), the global risk consulting
company, announced today that it has executed a definitive agreement to acquire
all of the outstanding shares of ONTRACK Data International, Inc. (Nasdaq: ONDI)
in a stock-for-stock merger. Ontrack is a leading provider of data recovery and
electronic discovery services, which are often used to support investigations,
litigation and other legal matters.

Under the agreement, the purchase price, payable in Kroll common stock, is
expected to be $12.50 per each outstanding share of Ontrack common stock,
subject to a collar. The purchase price will total approximately $140 million
based on the number of shares of Ontrack common stock currently outstanding,
plus issued stock options which will vest upon closing. The transaction is
expected to be immediately accretive to Kroll's per share earnings upon closing.
The transaction is anticipated to close late in the second quarter or early in
the third quarter of 2002, subject to customary closing conditions including
shareholder and regulatory approvals. The acquisition, which is intended to
qualify as a tax-free reorganization for Federal income tax purposes, has been
unanimously approved by Kroll's and Ontrack's boards of directors.

Ontrack, which had $55.8 million in revenues in 2001, specializes in recovering
data from operating systems and storage devices, and in providing electronic
discovery services to support investigations, litigation and other legal
matters. For the fourth quarter 2001, Ontrack reported revenues of $16.5 million
and net income of $1.2 million, or $0.12 per share. In a regular quarterly
conference call with investors held February 6, 2002, Ontrack management said
its 2002 total revenues would be in the range of $60.0 - $64.0 million and that
its 2002 earnings per share would be in the range of $0.43 - $0.53. It is
anticipated that Ontrack will have a minimum of $35.0 million of cash at
closing. Ontrack has no debt.

"Ontrack has excellent growth and profit metrics and is an outstanding strategic
fit for Kroll. Ontrack's expertise in recovering lost or corrupted data
complements our traditional strength in information-gathering and analysis, and
complements our mission of mitigating risk. This acquisition propels us into a
leadership position in the high-growth electronic discovery and computer
forensics market, which is anticipated to grow to more than $1 billion in the
U.S. alone," said Michael G. Cherkasky, president and chief executive officer of
Kroll Inc.

Cherkasky continued, "Although Kroll's electronic discovery and computer
forensics operations have seen strong growth over the past two years, our
strategic goals in this area could not be achieved through organic growth alone.






This acquisition immediately gives Kroll a solid, scalable platform that will
allow us to significantly expand the scope of our technology services.

"We fully expect to achieve the same results with Ontrack as we have with other
key acquisitions that have been successfully integrated into and cross-sold
through our platform," Cherkasky concluded.

"We are pleased to welcome Ontrack's management and employees to the Kroll
team," said Jules B. Kroll, executive chairman of the board. "The strategic and
operational fit between our two companies is superb. Now our prospects are even
better, thanks to the increased demand for electronic discovery and computer
forensics services stemming from the extensive number of accounting
irregularities under investigation in the United States."

Upon closing, Ontrack President and Chief Executive Officer Ben F. Allen will be
the president of a new Kroll business group, called the Data Recovery and
Discovery Group, which will be created to incorporate both companies' electronic
discovery and computer forensics operations.

"This is a great opportunity for Ontrack employees and shareholders," Allen
said. "Kroll's blue chip corporate and law firm clientele will allow us to
accelerate our sales strategy at a reduced cost and will provide an exceptional
channel for increasing our revenue base in electronic discovery and computer
forensics."

Allen further emphasized the international growth prospects for the business.
"With both companies well-established in Europe, we will be presented with many
cross-selling opportunities. Further, Kroll's offices in Asia and Latin America
provide a springboard to continue the geographic expansion of our data recovery
business." Kroll was advised in this transaction by Morgan, Lewis, Githens & Ahn
and the law firms of Torys LLP and Kramer Levin Naftalis & Frankel LLP. Ontrack
was advised by RBC Capital Markets and the law firm of Robins, Kaplan, Miller &
Ciresi L.L.P.
