TELETECH PROVIDES BUSINESS UPDATE
Continues Relationship with Wireless Division of Major Client;
Plans Fourth Quarter Charge to Strengthen its Competitive Position

Denver, Colo., December 19, 2002—TeleTech Holdings, Inc. (Nasdaq: TTEC), a leading global provider of customer management solutions, today provided an update on the status of a large client relationship and its overall business environment.

        TeleTech will continue its relationship with the wireless division of its largest telecommunications client. This program represented approximately four percent of TeleTech's revenues through the first nine months of 2002, or approximately $32 million. Under the new agreement, TeleTech will continue assisting consumers, as well as small and medium businesses, in obtaining new wireless services across certain U.S. regions.

        Additionally, as part of a continual review of its operations, TeleTech expects to exit or reduce the carrying value of certain customer management centers in its U.S., European, and Latin American operations to better position the company for future profitable growth. Furthermore, TeleTech will undertake a workforce reduction of approximately 200 professional employees. In addition, during the fourth quarter 2002, TeleTech acquired the shares of enhansiv holdings, inc. ("EHI") common stock from the four remaining outside shareholders of EHI. Consequently, TeleTech owns 100 percent of the common stock of EHI.

        As a result of the items described above, TeleTech expects to record a pre-tax charge in the fourth quarter 2002 ranging between $40 million and $50 million. Between $6 million and $10 million is estimated to be cash-related charges primarily for severance and the EHI transaction, with the remainder being non-cash charges for asset impairments. TeleTech believes the closure of customer management centers and the workforce reduction will take place throughout 2003.

        "I am pleased we will continue our relationship with the wireless division of our largest client and look forward to continuing to provide exceptional service to their wireless subscribers," said Kenneth Tuchman, TeleTech's Chairman and Chief Executive Officer.

        "Furthermore, the global economic environment continues to be challenging resulting in a sales cycle that has continued to lengthen. As a result, we must continually evaluate and streamline our operations to position the company for future growth opportunities," continued Tuchman. "We will continue to selectively pursue expansion into international locations that allow TeleTech to provide more competitive and flexible customer management solutions."

        "In light of the ongoing challenges in the global business environment, and upon careful assessment of our operations, it became necessary for TeleTech to evaluate certain assets and undertake a workforce reduction," said Margot O'Dell, TeleTech's Chief Financial Officer. "The resulting fourth quarter charge is primarily related to asset impairments of under-performing customer management centers, and will better position the company in the global customer management marketplace."

        "TeleTech continues to maintain a conservative balance sheet and generate significant free cash flows during a difficult economic period, while actively focusing on closing new business opportunities," continued O'Dell. "At the end of the third quarter 2002, TeleTech had a debt to capitalization ratio of 19 percent and $107.0 million of cash and short-term investments."

BUSINESS OUTLOOK

        TeleTech expects revenue and fully diluted earnings per share for the fourth quarter 2002 to be in line with its original guidance, before the effect of the charges discussed above. TeleTech expects fourth quarter 2002 revenue will range between $250 million and $255 million, while fully diluted earnings per share is expected to be at the low end of the company's original guidance of 7 cents to 9 cents, before the effect of the charges described above.

        The company expects to provide an update on the initiatives discussed above and its approach to providing 2003 earnings guidance when it announces fourth quarter 2002 results in February.
