TeleTech Receives NASDAQ Staff Determination Letter

Englewood, Colo., May 21, 2008 — TeleTech Holdings, Inc. (Nasdaq: TTEC) today announced the receipt of an Additional NASDAQ Staff Determination letter on May 15, 2008 indicating that the Company is not in compliance with the filing requirement for continued listing as set forth in Marketplace Rule 4310(c)(14) (the “May 15 Letter”). As anticipated, the letter was issued in accordance with NASDAQ procedures due to the delayed filing of the Company’s Quarterly Report on Form 10-Q for the period ended March 31, 2008 (the “March 31, 2008 Form 10-Q”), as discussed previously in the Notification of Late Filing filed on Form 12b-25 with the Securities and Exchange Commission (the “SEC”) on May 13, 2008. The May 15 Letter provides the Company the opportunity, until May 22, 2008, to present a written plan to cure the March 31, 2008 Form 10-Q late filing. The Company intends to submit information by May 22, 2008 to explain that the filing of the March 31, 2008 Form 10-Q has been delayed due to the pending restatements of the Company's historical financial statements.

As previously disclosed on May 7, 2008 in a Current Report on Form 8-K and press release, the NASDAQ Listing and Hearing Review Council (the “Listing Council”) stayed an earlier decision of the NASDAQ Listing Qualifications Panel requiring the filing of all required periodic reports by May 12, 2008. The Listing Council requested that the Company provide an update on its efforts to file all delayed and restated periodic reports by May 30, 2008. The Company intends to fully comply with this request and expects that its submission to the Listing Council due May 30, 2008 will also address its plan to file the March 31, 2008 Form 10-Q.

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 filings with the SEC as soon as practicable.
