TeleTech Receives Nasdaq Staff Determination Letter

Englewood, Colo., March 11, 2008 — TeleTech Holdings, Inc. (Nasdaq: TTEC) today announced the receipt of a NASDAQ Staff Determination letter on March 5, 2008 indicating that the Company is not in compliance with the filing requirements for continued listing as set forth in Marketplace Rule 4310(c)(14). As anticipated, the letter was issued in accordance with Nasdaq procedures due to the delayed filing of the Company’s Annual Report on Form 10-K for the year ended December 31, 2007 as discussed previously on the Form 12b-25 filed on March 3, 2008.

The Nasdaq Listing Qualifications Hearing Panel previously granted the Company until May 12, 2008 to become current in its delinquent and restated periodic reports. TeleTech is working diligently with its current and former independent auditors to finalize the quantification of the restatement adjustments and allocation among the periods impacted so as to become current with its periodic filings with the Securities and Exchange Commission by May 12, 2008.
