                                DEMAND GRID NOTE
                                ----------------

$65,000,000.00
October 29, 1997
Buffalo, New York

         FOR VALUE RECEIVED, the undersigned, Computer Task Group, Incorporated
Stock Employee Compensation Trust, with its principal business address at 200
Theatre Place, Buffalo, New York 14202 ("Borrower"), promises to pay to the
order of Computer Task Group, Incorporated ("Lender") in lawful money of the
United States, on demand (1) the principal amount of SIXTY FIVE MILLION
($65,000,000.00) DOLLARS, (the "Limiting Principal Amount") or the outstanding
principal amount of this Note (the "Outstanding Principal Amount"), if less, (2)
interest, calculated on the basis of a 365 day year on the Outstanding Principal
Amount from and including the date of this Note to but not including the date
the Outstanding Principal Amount is paid in full at a rate per year that shall
equal the prime rate of interest charged by Manufacturers and Traders Trust
Company; provided, however, that (i) in no event shall such interest be payable
at a rate in excess of the maximum rate permitted by applicable law and (ii)
solely to the extent necessary to result in such interest not being payable at a
rate in excess of such maximum rate, any amount that would be treated as part of
such interest under a final judicial interpretation of applicable law shall be
deemed to have been a mistake and automatically canceled, and, if received by
the Lender, shall be refunded to the Borrower, it being the intention of the
Lender and the Borrower that such interest not be payable at a rate in excess of
such maximum rate and (3) each cost and expense (including, but not limited to,
the reasonable fees and disbursements of counsel, whether retained for advice,
litigation or any other purpose) incurred by the Lender in endeavoring to (a)
collect any of the Outstanding Principal Amount, any interest payable pursuant
to this Note and remaining unpaid or any other amount payable by the Borrower to
the Lender pursuant to this Note and remaining unpaid, (b) preserve or exercise
any right or remedy of the Lender relating to, enforce or realize upon any
collateral, subordination, guaranty, endorsement or other security or assurance
of payment, whether now existing or hereafter arising, that now or hereafter
directly or indirectly secures the payment of or is otherwise now or hereafter
directly or indirectly applicable to any of the Outstanding Principal Amount,
any such interest or any such other amount or (c) preserve or exercise any right
or remedy of the Lender pursuant to this Note.

         This Note is issued by the Borrower to the Lender in connection with a
line of credit made available by the Lender to the Borrower (the "Credit"). The
Lender may make any loan pursuant to the Credit (individually a "Loan" and
collectively "Loans") in reliance upon any oral (including, but not limited to,
telephonic), written (including, but not limited to, facsimile) or other request
(a "Request") therefor that the Lender in good faith believes to be valid and to
have been made on behalf of the Borrower by its trustee. The Credit is available
subject to the Lender's continuing review and right of modification,
restriction, suspension or termination at any time for any reason. No
modification, restriction, suspension or termination of the Credit shall affect
the Borrower's obligation to repay the original principal amount of each Loan,
the Borrower's obligation to pay interest on the outstanding principal amount of
each Loan or any other obligation of the Borrower to the Holder pursuant to this
Note or otherwise.

         There shall be payable as principal pursuant to this Note only so much
of the Limiting Principal Amount as shall have been advanced by the Lender as a
Loan and is outstanding. The Holder shall set forth on the schedule attached to
and made a part of this Note or any similar schedule or loan (including, but not
limited to, any similar schedule or loan account maintained in computerized
records) annotations evidencing (1) the date and original principal amount of
each Loan and (2) the date and amount of each payment applied to the Outstanding
Principal Amount. Each such annotation shall, in the absence of manifest error,
be conclusive and binding upon the Borrower. No failure by the Holder to make
and no error by the Holder in making any annotation on such attached schedule or
any such similar schedule or loan account shall affect the obligation of the
Borrower to repay the principal amount of each Loan, the obligation of the
Borrower to pay interest on the outstanding principal amount of each Loan or any
other obligation of the Borrower pursuant to this Note.

                                                                              52

         All amounts payable pursuant to this Note and remaining unpaid shall,
without any notice, demand, presentment or protest of any kind (each of which is
knowingly, voluntarily, intentionally and irrevocably waived by the Borrower),
automatically become immediately due if the Borrower commences or has commenced
against it any bankruptcy or insolvency proceeding.

         This Note shall be governed by and construed, interpreted and enforced
in accordance with the internal law of the State of New York, without regard to
principles of conflict of laws.

         All payments of principal and interest under this Note are to be made
to the Lender at 800 Delaware Avenue, Buffalo, New York 14209, or at such other
address as the Lender may from time to time designate in writing.

                                ----------------

         In consideration of Computer Task Group, Incorporated with a principal

receipt of which is acknowledged by Pledgor, the Secured Party and the Pledgor
agree as follows:

         1. To secure the payment of all indebtedness, liabilities and

hereafter arising, directly or indirectly, and the performance of all other
obligations, that are now or hereafter owing by the Pledgor in any capacity to

personal responsibility is assumed by, or shall at any time be asserted or
enforceable against, the Pledgor in his individual capacity under, or with
respect to, this Agreement.

         3. The Pledgor shall upon the demand of the Secured Party (a) deliver
to the Secured Party each instrument included in the Collateral with each
endorsement, instrument of assignment and other writing that the Secured Party
shall reasonably deem necessary to accomplish the assignment or other transfer
of such instrument to the Secured Party and until such delivery hold such
instrument in trust for the Secured Party, (b) defend the Collateral against
each demand and claim asserted by any corporation, governmental authority,
individual, partnership or other entity (a "Person") other than the Secured

or claim relating to any of the Collateral, and (d) immediately send or deliver
to the Secured Party notice of any maturity, call, exchange, conversion,
redemption, offer, tender or similar matter relating to any of the Collateral.

Collateral, and each amendment of any such financing statement, that is so
requested and (b) execute and deliver each other writing, and take each other
action, that the Secured Party shall reasonably deem necessary (i) to perfect or
accomplish the security interest granted pursuant to this Agreement or (ii)
otherwise to accomplish any purpose of this Agreement.

                                                                             55
<PAGE>   2

or give any receipt, release or discharge relating to, any of the Collateral.

         6. Upon the failure of the Pledgor (a) to pay when due (or after
demand, where applicable) any amount, whether principal, interest or other,
constituting part of the Note and the continuation of such failure for more than
thirty (30) days after the Pledgor has received written notice of such failure
from the Secured Party (individually an "Event of Default"), the Secured Party
shall have the right, without any notice or demand of any kind, but shall not be
obligated, to perform any obligation of the Pledgor pursuant to this Agreement
and exercise each applicable right and remedy of a secured party pursuant to the
Uniform Commercial Code of the State of New York and each applicable right and
remedy pursuant to any other statute, regulation or other law. The Secured Party
shall apply all proceeds received by the Secured Party from any sale or other
disposition of, or from any collection of, any of the Collateral or otherwise on
account of any of the Collateral to such of the obligations, whether or not due,
as the Secured Party shall determine in the sole discretion of the Secured
Party.

         7. Upon the request of the Secured Party, the Pledgor shall (a) permit

and unconditionally appoints the Secured Party as the attorney-in-fact of the
Pledgor with full power of substitution and of revocation, acting at any time
and from time to time and without any notice or demand of any kind, in the name
of the Pledgor or otherwise and otherwise as shall be determined by the Secured
Party in the sole discretion of the Secured Party to, but the Secured Party
shall not be obligated to, take each action relating to any of the Collateral
that, subject to this Agreement, the Pledgor could take in the same manner, to
the same extent and with the same effect as if the Pledgor were to take such
action (including, but not limited to, the right to vote or give any consent,
ratification or waiver with respect to any of the Collateral to the extent
permitted by law and consistent with any rules and regulations of the Securities
and Exchange Commission). Without limiting the generality of the preceding
sentence, at all times prior to the occurrence of an Event of Default, the
Pledgor shall retain the right to vote or give any consent, ratification or
waiver with respect to the Collateral. Such power of attorney is coupled with an
interest in favor of the Secured Party.

         9. Upon the payment or forgiveness in any calendar quarter in any year
of any principal on the Note (a "Principal Payment"), the following number of
shares of Company Stock acquired with the proceeds of the Note shall become
released from the provisions of this Agreement and-shall no longer be
Collateral: the number of shares so acquired with the proceeds of the Note and
held by the Pledgor immediately before such payment or forgiveness, multiplied
by a fraction the numerator of which is the amount of the Principal Payment and
the denominator of which is the sum of such Principal Payment and the remaining
principal of the Note outstanding after such Principal Payment. No fractional
shares of Company Stock shall become released from the terms of this agreement.
If the preceding computation results in fractional shares, the number of
released shares shall be computed by rounding down to the next whole number.
Furthermore, the Secured Party from time to time may release shares of Company
Stock from the terms of this agreement as it shall designate in writing to the
Pledgor. Additionally, a number of shares of Company Stock as the Compensation
Committee of the Board of Directors of Computer Task Group, Incorporated shall
from time to time may declare shall be released from the provisions of this
Agreement and shall no longer be Collateral.

                                                                          56
<PAGE>   3

         10. This Agreement contains the entire agreement between the Secured
Party and the Pledgor with respect to the subject matter of this Agreement, and
supersedes each course of conduct heretofore pursued, accepted or acquiesced in,
and each oral agreement and representation heretofore made, by the Secured Party
with respect thereto, whether or not relied or acted upon. No course of
performance or other conduct hereafter pursued, accepted or acquiesced in, and
no oral agreement or representation hereafter made, by the Secured Party,
whether or not relied or acted upon, and no usage of trade, whether or not
relied or acted upon, shall modify or terminate this Agreement, impair or
otherwise affect any obligation of the Pledgor pursuant to this Agreement or any
right or remedy of the Secured Party pursuant to this Agreement or otherwise or
operate as a waiver of any such right or remedy. No modification of this
Agreement or waiver of any such right or remedy shall be effective unless made
in a writing duly executed by the Secured Party and the Pledgor.

         11. No obligation of the Pledgor or right or remedy of the Secured
Party pursuant to this Agreement shall be impaired or otherwise affected by, and
the Pledgor consents without notice to, (a) any extension, renewal, refinancing,
modification, acceleration, invalidity or unenforceability of the Note, (b) any
replacement, release or discharge of any party liable for payment of the Note,
(c) any impairment, replacement, release or discharge of, or failure to call
for, take, hold, protect, perfect, keep perfected or enforce any security
interest in or other lien or encumbrance upon, any collateral or other security
securing the Note and (d) any exercise, delay in the exercise or waiver of,
failure to exercise or forbearance or other indulgence by the Secured Party
relating to any such right or remedy. No such obligation, right or remedy shall
be conditioned upon, and the Pledgor waives, without notice, any demand,
presentment or protest, any notice of nonpayment, of protest or of any other
matter and any exercise of any right or remedy.

         12. All rights and remedies of the Secured Party pursuant to this
Agreement or otherwise shall be cumulative, and no such right or remedy shall be
exclusive of any other such right or remedy. No single or partial exercise by
the Secured Party or any such right or remedy shall preclude any other of
further exercise thereof, or any exercise of any other such right or remedy, by
the Secured Party. The Secured Party hereby delegates to the Compensation
Committee of the Board of Directors of the Secured Party the authority to
exercise in its discretion all rights and remedies under this Agreement.

         13. Each notice to and each other communication to the Pledgor or the
Secured Party shall be hand-delivered or sent by certified mail, return receipt
requested, to the address set forth for such party at the beginning of this
Agreement or to any other address as may at any time be specified by such party
in a written notice delivered pursuant to this Section.

         14. This Agreement shall be governed by and interpreted and enforced in
accordance with the internal law of the State of New York, without regard to

         15. This Agreement shall be binding upon the Pledgor and upon each
successor and assignee of the Pledgor, and shall inure to the benefit of, and be
enforceable by, the Secured Party and each successor and assignee of the Secured
Party.

         16. Whenever possible, each provision of this Agreement shall be
interpreted in such a manner as to be effective and valid under applicable law.
If, however, any such provision shall be prohibited by or invalid under such
law, it shall be deemed modified to conform to the minimum requirements of such
law, or if for any reason it is not deemed so modified, it shall deemed modified
to conform to the minimum requirements of such law, or if for any reason it is
not deemed so modified, it shall be prohibited or invalid only to the extent of
such prohibition or invalidity without the remainder thereof or any other such
provision being prohibited or invalid.

                                                                           57
