TECHTEAM REVEALS INTERNAL INVESTIGATION INTO POSSIBLE MISCONDUCT

BOARD 'PUZZLED' BY COSTA BRAVA'S ABRUPT TERMINATION OF TALKS FOLLOWING
REVELATION


SOUTHFIELD, MICHIGAN, April 4, 2006... TechTeam Global, Inc. (Nasdaq: TEAM) (the
"Company" or "TechTeam") Board of Directors revealed today that before Costa
Brava Partnership III, L.P. ("Costa Brava") abruptly ended discussions about a
unity slate of directors last Friday, the Board had asked for a delay in
concluding the agreement pending the outcome of an internal investigation into
possible misconduct by the Company's Chief Financial Officer, who was
responsible for investor relations.

"We have serious concerns about the potential misconduct, and we are working to
finalize our investigation so we can understand the full ramifications of the
potential misconduct both inside and outside the Company," said Board Chairman
Kim A. Cooper. "So we informed Costa Brava that we felt it necessary to wait
until our independent legal counsel completes its inquiry into possible
unauthorized disclosure of confidential information to Costa Brava."

Cooper emphasized that the potential misconduct by the Company's Chief Financial
Officer did not relate to the Company's financial statements, and therefore, the
integrity of the company's financial statements is not in question.

"In view of the circumstances, we are both disappointed and puzzled that Costa
Brava elected to unilaterally terminate discussions," Cooper said. "We had hoped
that they would agree to delay their plan to wage a proxy contest until the
relevant facts could be discovered. Pending the outcome of the inquiry, the
Board may wish to seek a resumption of discussions with Costa Brava."

The Company's former Chief Financial Officer, David W. Morgan, was suspended
Wednesday, March 29, 2006, and subsequently resigned. Marc J. Lichtman, who has
been TechTeam's Vice President and Chief Accounting Officer since 2004, will
continue to oversee the Company's financial functions.

The internal investigation is being led by David Bohan, a partner at Sachnoff &
Weaver, a Chicago law firm retained late last year as independent counsel to the
TechTeam Board. Bohan is a Harvard Law School graduate and a former federal
prosecutor who heads his firm's Securities Litigation and Regulation Practice
Group. He has experience in conducting internal corporate investigations on
behalf of corporate boards.

at the Company's annual shareholder meeting. Since that time, the sitting Board
has been working to reach an agreement with Costa Brava that would avert a
costly proxy contest and serve the best interests of all shareholders through
the nomination of a unity slate of directors.
