The aggregate market value of the Registrant's common stock held by
non-affiliates of the registrant as of June 30, 2004 was approximately
$73,161,000 (based on the June 30, 2004 closing sales price of $9.07 of the
Registrant's common stock, as reported on the NASDAQ(R) National Stock Market).
For the sole purpose of making this calculation, the term "non-affiliates" has
been interpreted to exclude directors and executive officers of the Company.
Such interpretation is not intended to be, and should not be construed to be, an
admission by TechTeam Global, Inc. or such directors or executive officers of
the Company that such directors and executive officers of the Company are
"affiliates" of TechTeam Global, Inc., as that term is defined under the
Securities Act of 1934.

The number of shares outstanding of the registrant's common stock as of March
11, 2005 was 8,775,970.

                                EXPLANATORY NOTE

TechTeam Global, Inc. (collectively with its subsidiaries, the "Company,"
"TechTeam," "we," "us" and "our") is filing this Amendment No. 1 to Form 10-K/A
("Amendment No. 1") solely to amend its disclosures in Item 9A of Part II
contained in its Annual Report on Form 10-K for the fiscal year ended December
31, 2004 (the "Form 10-K"), which was originally filed with the Securities and
Exchange Commission (the "SEC") on March 18, 2005. The purpose of this Amendment
No. 1 is to address comments that TechTeam received from the Staff of the
Division of Corporation Finance of the SEC.

Pursuant to Rule 12b-15 under the Securities and Exchange Act of 1934, as
amended, this Amendment No. 1 contains the complete text of Item 9A of Part II,
as amended, and new certifications pursuant to Section 302 of the Sarbanes-Oxley
Act of 2002. The representations contained in the new certifications continue to
relate solely to our fiscal year ended December 31, 2004. This Amendment No. 1
contains only the sections and exhibits to the Form 10-K that are being amended
and restated. The sections of and exhibits to the Form 10-K as originally filed,
which are not included herein, are unchanged and continue in full force and
effect as originally filed. This Amendment No. 1 speaks as of the date of the
original filing of the Form 10-K and has not been updated to reflect events
occurring subsequent to the original filing date.

                                     PART II

ITEM 9A. CONTROLS AND PROCEDURES

As of December 31, 2004, an evaluation was performed under the supervision and
with the participation of the Company's management, including our Chief
Executive Officer, Chief Financial Officer, and Chief Accounting Officer, of the
effectiveness of the design and operations of the Company's disclosure controls
and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities
Exchange Act of 1934. Based upon that evaluation, the Company's Management,
including our Chief Executive Officer, Chief Financial Officer, and Chief
Accounting Officer, concluded that the Company's disclosure controls and
procedures were effective as of December 31, 2004.

As required by Rule 13(a)-15d under the Securities Exchange Act of 1934, the
Company's management, including our Chief Executive Officer, Chief Financial
Officer, and Chief Accounting Officer, also conducted an evaluation of the
Company's internal control over financial reporting to determine whether any
changes occurred during the quarter ended December 31, 2004 that have materially
affected, or are reasonably likely to materially affect, the Company's internal
control over financial reporting. Based on that evaluation, there has been no
such change during the quarter ended December 31, 2004. On January 3, 2005, we
acquired Sytel, Inc., which expanded our internal controls over financial
reporting and disclosure.
