                                     PART II


ITEM 9A.  CONTROLS AND PROCEDURES


(a) EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

The Company's management has evaluated, under the supervision and with the
participation of the Company's Chief Executive Officer and Chief Financial
Officer, the effectiveness of the design and operations of the Company's
disclosure controls and procedures (as defined in Securities Exchange Act Rule
13a-15(e)), as of the end of the period covered by this annual report. Based on
that evaluation, and due to the material weaknesses in the Company's internal
control over financial reporting (as described below in Management's Annual
Report on Internal Control Over Financial Reporting), the Company's Chief
Executive Officer and Chief Financial Officer have concluded that the Company's
disclosure controls and procedures were not effective as of the end of the
period covered by this annual report.

(b) MANAGEMENT'S ANNUAL REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The Company's management is responsible for establishing and maintaining an
adequate system of internal control over financial reporting. Internal control
over financial reporting is a process designed to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of
financial statements for external purposes in accordance with generally accepted
accounting principles. A company's internal control over financial reporting
includes those policies and procedures that (i) pertain to the maintenance of
records that, in reasonable detail, accurately and fairly reflect the
transactions and dispositions of the assets of the company; (ii) provide
reasonable assurance that transactions are recorded as necessary to permit
preparation of financial statements in accordance with generally accepted
accounting principles, and that receipts and expenditures of the company are
being made only in accordance with authorizations of management and directors of
the company; and (iii) provide reasonable assurance regarding prevention or
timely detection of unauthorized acquisition, use, or disposition of the
company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, a system of internal control over financial
reporting can provide only reasonable assurance and may not prevent or detect
misstatements. Therefore, even those systems determined to be effective can
provide only reasonable assurance with respect to financial statement
preparation and presentation. Further, because of changes in conditions,
effectiveness of internal control over financial reporting may deteriorate.

A significant deficiency is a control deficiency, or combination of control
deficiencies, that adversely affects the company's ability to initiate,
authorize, record, process, or report external financial data reliably in
accordance with generally accepted accounting principles such that there is more
than a remote likelihood that a misstatement of the company's annual or interim
financial statements that is more than inconsequential will not be prevented or
detected. An internal control material weakness is a significant deficiency, or
combination of significant deficiencies, that results in more than a remote
likelihood that a material misstatement of the annual or interim financial
statements will not be prevented or detected.

Management of the Company conducted an evaluation of the effectiveness of the
Company's internal control over financial reporting based on the Internal
Control-Integrated Framework issued by the Committee of Sponsoring Organizations
of the Treadway Commission. Based on that evaluation, the Company's management
identified two control deficiencies it considered to be material weaknesses
under the rules specified by the Public Company Accounting Oversight Board's
Auditing Standard No. 2, and therefore concluded that its internal control over
financial reporting was not effective as of December 31, 2004. The material
weaknesses identified relate to internal control over financial reporting
associated with the Company's accounting for income taxes and its accounting for
medical self-insurance reserves, as described below.


                                                                               3

As of December 31, 2004, management identified a material weakness in internal
control over financial reporting associated with the Company's accounting for
income taxes. Specifically, the Company did not have effective management
oversight and review controls to ensure that the Company's income tax accounting
was consistent with generally accepted accounting principles. This control
deficiency resulted in errors in the Company's accounting for both current and
deferred income tax amounts and related disclosures, which were corrected prior
to issuance of the Company's 2004 financial statements.

Additionally, as of December 31, 2004, management identified a deficiency in
internal control over financial reporting associated with the Company's
calculation of its incurred but not reported claims related to its self-insured
medical insurance programs. Specifically, the Company's policies and procedures
associated with the calculation of these incurred but not reported claims did
not include an evaluation of the underlying assumptions used to estimate future
claims liabilities to reflect recent claims development experience. This
deficiency resulted in a material understatement of the Company's recorded
medical self-insurance reserves. This error in accounting was corrected prior to
issuance of the Company's 2004 financial statements.

KPMG LLP, an independent registered public accounting firm, has issued a report
on management's assessment of the Company's internal control over financial
reporting, which is included herein.


(c) CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

We continue to review, revise and improve the effectiveness of the Company's
internal controls including the additional controls implemented relating to the
Company's medical costs including the estimation of medical self-insurance
reserves, and strengthening the Company's income tax review control procedures
noted above. We have made no other significant changes in the Company's internal
controls over financial reporting in connection with the Company's fourth
quarter evaluation that would materially affect, or are reasonably likely to
materially affect the Company's internal controls over financial reporting.


                                                                               4

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


The Board of Directors and Shareholders
Computer Task Group, Incorporated:

We have audited management's assessment, included in the accompanying
Management's Report on Internal Control Over Financial Reporting (Item 9A(b)),
that Computer Task Group, Incorporated (the Company) did not maintain effective
internal control over financial reporting as of December 31, 2004, because of
the effect of material weaknesses identified in management's assessment, based
on criteria established in Internal Control--Integrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission (COSO). The
Company's management is responsible for maintaining effective internal control
over financial reporting and for its assessment of the effectiveness of internal
control over financial reporting. Our responsibility is to express an opinion on
management's assessment and an opinion on the effectiveness of the Company's
internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether effective
internal control over financial reporting was maintained in all material
respects. Our audit included obtaining an understanding of internal control over
financial reporting, evaluating management's assessment, testing and evaluating
the design and operating effectiveness of internal control, and performing such
other procedures as we considered necessary in the circumstances. We believe our
audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed to
provide reasonable assurance regarding the reliability of financial reporting
and the preparation of financial statements for external purposes in accordance
with generally accepted accounting principles. A company's internal control over
financial reporting includes those policies and procedures that (1) pertain to
the maintenance of records that, in reasonable detail, accurately and fairly
reflect the transactions and dispositions of the assets of the company; (2)
provide reasonable assurance that transactions are recorded as necessary to
permit preparation of financial statements in accordance with generally accepted
accounting principles, and that receipts and expenditures of the company are
being made only in accordance with authorizations of management and directors of
the company; and (3) provide reasonable assurance regarding prevention or timely
detection of unauthorized acquisition, use, or disposition of the company's
assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting
may not prevent or detect misstatements. Also, projections of any evaluation of
effectiveness of future periods are subject to the risk that controls may become
inadequate because of changes in conditions, or that the degree of compliance
with the policies or procedures may deteriorate.

A material weakness is a control deficiency, or combination of control
deficiencies, that results in more than a remote likelihood that a material
misstatement of the annual or interim financial statements will not be prevented
or detected. The following material weaknesses have been identified and included
in management's assessment.

As of December 31, 2004, management identified a material weakness in internal
control over financial reporting associated with the Company's accounting for
income taxes. Specifically, the Company, did not have effective management
oversight and review controls to ensure that the Company's income tax accounting
was consistent with generally accepted accounting principles. This control
deficiency resulted in errors in the Company's accounting for both current and
deferred income tax amounts and related disclosures, which were corrected prior
to issuance of the Company's 2004 financial statements.


                                                                               5

Additionally, as of December 31, 2004, management identified a deficiency in
internal control over financial reporting associated with the Company's
calculation of its incurred but not reported claims related to its self-insured
medical insurance programs. Specifically, the Company's policies and procedures
associated with the calculation of these incurred but not reported claims did
not include an evaluation of the underlying assumptions used to estimate future
claims liabilities to reflect recent claims development experience. This
deficiency resulted in a material understatement of the Company's recorded
medical self-insurance reserves. This error in accounting was corrected prior to
issuance of the Company's 2004 financial statements.

We also have audited, in accordance with the standards of the Public Company
Accounting Oversight Board (United States), the consolidated financial
statements of the Company and subsidiaries as of December 31, 2004. These
material weaknesses have been considered in determining the nature, timing, and
extent of audit tests applied in our audit of the 2004 consolidated financial
statements, and this report does not affect our report dated March 14, 2005,
which expressed an unqualified opinion on those consolidated financial
statements.

In our opinion, management's assessment that the Company did not maintain
effective internal control over financial reporting as of December 31, 2004, is
fairly stated, in all material respects, based on criteria established in
Internal Control--Integrated Framework issued by COSO. Also, in our opinion,
because of the effect of the material weaknesses described above on the
achievement of the objectives of the control criteria, the Company has not
maintained effective internal control over financial reporting as of December
31, 2004, based on criteria established in Internal Control--Integrated
Framework issued by COSO.
