                 AMENDED AND RESTATED GUIDANCE PROMISSORY NOTE


$10,000,000.00                                    Date:   _____________, _______

  FOR VALUE RECEIVED, KEANE, INC. (the "Borrower"), a Massachusetts corporation
with a principal place of business at 10 City Square, Boston, Massachusetts,
hereby promises to pay to the order of FLEET NATIONAL BANK, a national banking
association (the "Bank") at the office of the Bank at 100 Federal Street,
Boston, Massachusetts 02110, or at such other address as the holder hereof may
designate, the principal sum of TEN MILLION DOLLARS ($10,000,000.00), or the
aggregate unpaid principal amount of all Advances made by the Bank to the
Borrower hereunder (collectively, the "Advances" and each individually, an
"Advance"), whichever is less, in lawful money of the United States in
immediately available funds, and to pay interest on each Advance as set forth
below and to pay all taxes levied or assessed upon said Advances against any
holder of this Note and to pay all costs, including attorneys' fees, costs
relating to the appraisal and/or valuation of assets and all costs incurred in
the collection, defense, preservation, administration, enforcement or protection
of this Note or in any guaranty or endorsement of this Note, or in any
litigation arising out of the transactions of which this Note or any guaranty or
endorsement of this Note is a part. All payments, including any prepayments,
shall be applied first to the payment of all fees, expenses and other amounts
due to the Bank (excluding principal and interest), then to accrued interest,
and the balance on account of outstanding principal; provided, however, that
after default, payments will be applied to the obligations of the Borrower to
the Bank as the Bank determines in its sole discretion.

  This Note has been executed and delivered subject to the following terms and
conditions:

  1.  ADVANCES.  (a) Pursuant to the terms of this Note and upon satisfaction of
the conditions precedent referred to herein, the Borrower may, in its sole
discretion, borrow from the Bank, Advances not to exceed the aggregate principal
amount of Ten Million Dollars ($10,000,000.00) at any one time outstanding. The
Borrower may request such Advances on any Business Day from the date hereof up
to and including July 30, 2002 (as such date may be extended, in writing from
time to time, in the Bank's sole and absolute discretion, the "Termination
Date").  This Note does not constitute a commitment to make Advances to the
Borrower, and the making of an Advance at any time shall not be deemed a waiver
of, or consent, agreement or commitment by the Bank to the making of any future
Advance to the Borrower.  Advances may be Prime Rate Advances (defined below) or
Fixed Rate Advances (defined below), at the Borrower's option. (b) If any
Advance is made, the Bank may, at its option, record on the books and records of
the Bank or endorse on Schedule 1 hereto, an appropriate notation evidencing any
Advance, the interest rate applicable to such Advance, the date such Advance is
due, each repayment on account of the principal thereof, and the amount of
interest paid; and the Borrower authorizes the Bank to maintain such records or
make such notations and agrees that the amount shown on the books and records or
on said Schedule 1, as applicable, as outstanding from time to time shall
constitute the amount owing to the Bank pursuant to this Note, absent manifest
error.  In the event the amount shown on Schedule 1 conflicts with the amount
noted as due pursuant to the books and records of the Bank, the books and
records of the Bank shall control the disposition of the conflict.

  2.  REPAYMENT OF ADVANCES.  (a) The Borrower shall repay the aggregate unpaid
principal amount of all Prime Rate Advances made by the Bank at the earlier of
(i) the date such Advance is due as set forth on Schedule 1 hereto and/or on the
Bank's books and records, as the case may be, or (ii) ON DEMAND, but if not
sooner demanded, demand shall be deemed to be made on the Termination Date; (b)
The Borrower shall repay each Fixed Rate Advance at the earlier of (i) the date
such Fixed Rate Advance is due as agreed to by the Bank and the Borrower at the
time of such Fixed Rate Advance and as set forth on Schedule 1 hereto and/or on
the Bank's books and records, as the case may be, or (ii) ON DEMAND, but if not
sooner demanded, demand shall be deemed to be made on the Termination Date.

  The Bank is hereby authorized (but not required) to charge principal and
interest due on this Note and all other amounts due hereunder to any account of
the Borrower when and as it becomes due. All payments shall be made by the
Borrower to the Bank at 100 Federal Street, Boston, Massachusetts 02110 or such
other place as the Bank may from time to time specify in writing in lawful
currency of the United States of America in immediately available funds, without
counterclaim or setoff and free and clear of, and without any deduction or
withholding for, any taxes or other payments. As used herein, "Business Day"
shall mean any day other than a Saturday, Sunday or day which shall be in the
Commonwealth of Massachusetts and a legal holiday or day on which banking
institutions are required or authorized to close.  If this Note or any payment
hereunder becomes due on a day which is not a Business Day, the due date of this
<PAGE>

Note or payment shall be extended to the next succeeding Business Day, and such
extension of time shall be included in computing interest and fees in connection
with such payment.

  3.  INTEREST RATE; ADDITIONAL CHARGES; FEE.  (a) The Bank shall notify the
Borrower of the interest rate applicable to each Advance.  If an Advance bears
interest at a variable per annum rate equal to the Prime Rate ("Prime Rate
Advance") such Advance will be payable monthly on the first day of each month,
commencing on the first of such dates next succeeding such Prime Rate Advance
and upon payment of such Prime Rate Advance.  If an Advance bears interest at a
per annum fixed rate agreed upon by the Borrower and the Bank ("Fixed Rate
Advance") such Advance will be due and payable as set forth on Schedule 1 hereto
and interest thereon will be payable monthly, commencing on the corresponding
day of the month immediately succeeding the date of such Fixed Rate Advance, and
on said due date.  After the due date of any Fixed Rate Advance as defined in
Section 2(b)(i) above or upon the failure to pay any Fixed Rate Advance or any
Prime Rate Advance on demand or after judgment has been rendered on this Note,
the unpaid principal balance of all Advances shall, at the option of the Bank,
bear interest at a rate which is four (4) percentage points per annum greater
than the Prime Rate.  As used herein, the term "Prime Rate" shall mean the
variable per annum rate of interest so designated from time to time by the Bank
as its prime rate.  The Prime Rate is a reference rate and does not necessarily
represent the lowest or best rate being charged to any borrower.  Changes in the
rate of interest resulting from changes in the Prime Rate shall take place
immediately without notice or demand of any kind.  Interest on this Note shall
be computed on the basis of a 360-day year and actual days elapsed.

  (b) If the Bank shall deem applicable to this Note, (including, in each case,
any borrowed and any unused portion thereof), any requirement of any law of the
United States of America, any regulation, order, interpretation, ruling,
official directive or guideline (whether or not having the force of law) of the
Board of Governors of the Federal Reserve System, the Comptroller of the
Currency, the Federal Deposit Insurance Corporation or any other board or
governmental or administrative agency of the United States of America which
shall impose, increase, modify or make applicable to this Note or cause this
Note to be included in any reserve, special deposit, calculation used in the
computation of regulatory capital standards, assessment or other requirement
which imposes on the Bank any cost that is attributable to the maintenance
thereof, then, and in each such event, the Borrower shall promptly pay the Bank,
upon its demand, such amount as will compensate the Bank for any such cost,
which determination may be based upon the Bank's reasonable allocation of the
aggregate of such costs resulting from such events.  In the event any such cost
is a continuing cost, a fee payable to the Bank may be imposed upon the Borrower
periodically for so long as any such cost is deemed applicable to the Bank, in
an amount determined by the Bank to be necessary to compensate the Bank for any
such cost, which determination may be based upon the Bank's reasonable
allocation of the aggregate of such costs resulting from such events.  The
determination by the Bank of the existence and amount of any such additional
costs shall, in the absence of manifest error, be conclusive.

  (c) All agreements between the Borrower and the Bank are hereby expressly
limited so that in no contingency or event whatsoever shall the amount paid or
agreed to be paid to the Bank for the use or the forbearance of the indebtedness
evidenced hereby exceed the maximum permissible under applicable law.  As used
herein, the term "applicable law" shall mean the law in effect as of the date
hereof; provided, however, that in the event there is a change in the law which
results in a higher permissible rate of interest, then this Note shall be
governed by such new law as of its effective date.  In this regard, it is
expressly agreed that it is the intent of the Borrower and the Bank in the
execution, delivery and acceptance of this Note to contract in strict compliance
with the laws of the Commonwealth of Massachusetts from time to time in effect.
If, under or from any circumstances whatsoever, fulfillment of any provision
hereof at the time of performance of such provision shall be due, shall involve
transcending the limit of such validity prescribed by applicable law, then the
obligation to be fulfilled shall automatically be reduced to the limits of such
validity, and if under or from circumstances whatsoever the Bank should ever
receive as interest an amount which would exceed the highest lawful rate, such
amount which would be excessive interest shall be applied to the reduction of
the principal balance evidenced hereby and not to the payment of interest.  This
provision shall control every other provision of all agreements between the
Borrower and the Bank.

  4.  LATE CHARGE.  If the entire amount of any required principal and/or
interest is not paid in full within ten (10) days after the same is due, the
Borrower shall pay to the Bank a late fee equal to five percent (5%) of the
required payment.

                                      -2-

  5.  PAYMENTS; CHARGES.  The Borrower may not prepay any Fixed Rate Advance
prior to the due date noted on Schedule 1 with respect to such Fixed Rate
Advance.  In the event that a prepayment of a Fixed Rate Advance is permitted or
required hereunder, the Borrower shall pay to Bank a yield maintenance fee in an
amount computed as follows:  The current rate for United States Treasury
securities (bills on a discounted basis shall be converted to a bond equivalent)
with a maturity date closest to the due date of the term chosen pursuant to the
Fixed Rate Advance as to which the prepayment is made, shall be subtracted from
the "Cost of Funds" or "LIBOR", as applicable, component of the fixed rate in
effect at the time of prepayment.  If the result is zero or a negative number,
there shall be no yield maintenance fee.  If the result is a positive number,
then the resulting percentage shall be multiplied by the amount of the principal
balance being prepaid.  The resulting amount shall be divided by 360 and
multiplied by the number of days remaining in the term chosen pursuant to the
Fixed Rate Advance as to which the prepayment is made.  Said amount shall be
reduced to present value calculated by using the above-referenced United States
Treasury securities rate and the number of days remaining in the term chosen
pursuant to the Fixed Rate Advance as to which the prepayment is made.  The
resulting amount shall be the yield maintenance fee due to Bank upon prepayment
of the Fixed Rate Advance.  "Cost of Funds" as used herein shall mean the per
annum rate of interest which the Bank is required to pay, or is offering to pay,
for wholesale liabilities of like tenor, adjusted for reserve requirements and
such other requirements as may be imposed by federal, state, or local government
and regulatory agencies, as determined by the Bank.  "LIBOR" as used herein
shall mean, as applicable to any LIBOR loan ("LIBOR Loan") the rate per annum
(rounded upward, if necessary, to the nearest 1/32 of one percent) as determined
on the basis of the offered rates for deposits in U.S. dollars, for a period of
time comparable to such LIBOR Loan which appears on the Telerate page 3750 as of
11:00 a.m. London time on the day that is two (2) Business Days preceding the
first day of such LIBOR Loan; provided, however, if the rate described above
does not appear on the Telerate System on any applicable interest determination
date, the LIBOR rate shall be the rate (rounded upwards as described above, if
necessary), for deposits in dollars for a period substantially equal to the
interest period on the Reuters Page "LIBO" (or such other page as may replace
the LIBO Page on that service for the purpose of displaying such rates), as of
11:00 a.m. (London time), on the day that is two (2) Business Days prior to the
beginning of such interest period.  If both the Telerate and Reuters systems are
unavailable, then the rate for that date will be determined on the basis of the
offered rates for deposits in U.S. dollars for a period of time comparable to
such LIBOR Loan which are offered by four major banks in the London interbank
market at approximately 11:00 a.m. London time, on the day that is two Business
Days preceding the first day of such LIBOR Loan as selected by the Bank.  The
principal London office of each of the four major London banks will be requested
to provide a quotation of its U.S. dollar deposit offered rate.  If at least two
such quotations are provided, the rate for that date will be the arithmetic mean
of the quotations.  If fewer than two quotations are provided as requested, the
rate for that date will be determined on the basis of the rates quoted for loans
in U.S. dollars to leading European banks for a period of time comparable to
such LIBOR Loan offered by major banks in New York City at approximately 11:00
a.m. New York City time, on the day that is two Business Days preceding the
first day of such LIBOR Loan.  In the event that the Bank is unable to obtain
any such quotation as provided above, it will be deemed that LIBOR pursuant to a
LIBOR Loan cannot be determined.  In the event that the Board of Governors of
the Federal Reserve System shall impose a Reserve Percentage with respect to
LIBOR deposits of the Bank, then for any period during which such Reserve
Percentage shall apply, LIBOR shall be equal to the amount determined above
divided by an amount equal to 1 minus the Reserve Percentage.

  The Borrower may repay any Prime Rate Advance at any time in whole or in part
without penalty or premium.  If, at any time, the aggregate principal amount of
all Advances outstanding under this Note shall exceed the maximum amount
permitted by this Note, the Borrower shall immediately repay so much of the
outstanding principal balance, together with accrued interest on the portion of
principal so repaid, as shall be necessary in order that the unpaid principal
balance, after giving effect to such prepayments, shall not be in excess of the
maximum amount permitted by this Note.  All such payments shall be applied first
to the payment of all interest accrued to the date of payment and the remainder
to the principal balances as instructed by the Borrower.

  6.  REPRESENTATIONS AND WARRANTIES.  The Borrower hereby represents and
warrants to the Bank (which representations and warranties will survive the

  10. LIEN AND SET-OFF.  The Borrower hereby grants to the Bank a continuing

<PAGE>

of the Bank or any entity under the control of FleetBoston Financial Corporation
or in transit to any of them. At any time, without demand or notice (any such
notice being expressly waived by the Borrower), the Bank may set off the same or
any part thereof and apply the same to any liability or obligation of the
Borrower even though unmatured and regardless of the adequacy of any other
collateral securing the loan evidenced hereby.  TO THE EXTENT PERMITTED BY LAW,
ANY AND ALL RIGHTS TO REQUIRE THE BANK TO EXERCISE ITS REMEDIES WITH RESPECT TO

OF SET OFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF THE
BORROWER, ARE HEREBY VOLUNTARILY, INTENTIONALLY, AND IRREVOCABLY WAIVED.

  11. JURY TRIAL WAIVER; DAMAGES.  THE BORROWER AND THE BANK (BY ACCEPTANCE OF
THIS NOTE) MUTUALLY HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE THE
RIGHT TO A TRIAL BY JURY IN RESPECT OF ANY CLAIM BASED HEREON, ARISING OUT OF,
UNDER OR IN CONNECTION WITH THIS NOTE OR ANY OTHER LOAN DOCUMENTS CONTEMPLATED
TO BE EXECUTED IN CONNECTION HEREWITH ("LOAN DOCUMENTS") OR ANY COURSE OF
CONDUCT, COURSE OF DEALINGS, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS
OF ANY PARTY, INCLUDING, WITHOUT LIMITATION, ANY COURSE OF CONDUCT, COURSE OF
DEALINGS, STATEMENTS OR ACTIONS OF THE BANK RELATING TO THE ADMINISTRATION OF
THE LOAN OR ENFORCEMENT OF THE LOAN DOCUMENTS, AND AGREE THAT NEITHER PARTY WILL
SEEK TO CONSOLIDATE ANY SUCH ACTION WITH ANY OTHER ACTION IN WHICH A JURY TRIAL
CANNOT BE OR HAS NOT BEEN WAIVED.   EXCEPT AS PROHIBITED BY LAW, THE BORROWER
HEREBY WAIVES ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY LITIGATION ANY
SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES OTHER THAN,
OR IN ADDITION TO, ACTUAL DAMAGES.  THE BORROWER CERTIFIES THAT NO
REPRESENTATIVE, AGENT OR ATTORNEY OF THE BANK HAS REPRESENTED, EXPRESSLY OR
OTHERWISE, THAT THE BANK WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE
THE FOREGOING WAIVER.  THIS WAIVER CONSTITUTES A MATERIAL INDUCEMENT FOR THE
BANK TO ACCEPT THIS NOTE AND MAKE ADVANCES HEREUNDER.

  12.  PLEDGE TO THE FEDERAL RESERVE BANK. The Bank may at any time pledge or
assign all or any portion of its rights under the Loan Documents including any
portion of this Note to any of the twelve (12) Federal Reserve Banks organized
under Section 4 of the Federal Reserve Act, 12 U.S.C. Section 341.  No such
pledge or assignment or enforcement thereof shall release the Bank from its
obligations under any of the Loan Documents.

  13.  SALE OF PARTICIPATION.   The Bank shall have the unrestricted right at
any time and from time to time, and without the consent of or notice to the
Borrower, to grant to one or more banks or other financial institutions (each, a
"Participant") participating interests in the Bank's obligation to lend
hereunder and/or any or all of the loans held by the Bank hereunder.  In the
event of any such grant by the Bank of a participating interest to a Participant
whether or not upon notice to the Borrower, the Bank shall remain responsible
for the performance of its obligations hereunder and the Borrower shall continue
to deal solely and directly with the Bank in connection with the Bank's rights
and obligations hereunder.  The Bank may furnish any information concerning the
Borrower in its possession from time to time to prospective assignees and
Participants, provided that the Bank shall require any such prospective assignee
or Participant to agree in writing to maintain the confidentiality of such
information.

  14.  LOST DOCUMENT.  Upon receipt of an affidavit of an officer of the Bank as
to the loss, theft, destruction or mutilation of the Note or any other security
document which is not of public record, and, in the case of any such loss,
theft, destruction or mutilation, upon cancellation of such Note or other
security document, the Borrower will issue, in lieu thereof, a replacement note
or other security document in the same principal amount thereof and otherwise of
like tenor.

  15. ASSIGNMENT.  The Bank shall have the unrestricted right at any time or
from time to time, and without Borrower's consent, to assign all or any portion
of its rights and obligations hereunder to one or more banks or other financial
institutions (each, an "assignee"), and the Borrower agrees that it shall

                                      -6-
<PAGE>

execute, or cause to be executed, such documents, including without limitation,
amendments to this Note and to any other documents, instruments and agreements
executed in connection herewith as the Bank shall deem necessary to effect the
foregoing.  In addition, at the request of the Bank and any such assignee, the
Borrower shall issue one or more new promissory notes, as applicable, to any
such assignee and, if the Bank has retained any of its rights and obligations
hereunder following such assignment, to the Bank, which new promissory notes
shall be issued in replacement of, but not in discharge of, the liability
evidenced by the promissory note held by the Bank prior to such assignment and
shall reflect the amount of the respective commitments and loans held by such
assignee and the Bank after giving effect to such assignment.  Upon the
execution and delivery of appropriate assignment documentation, amendments and
any other documentation required by the Bank in connection with such assignment,
and the payment by assignee of the purchase price agreed to by the Bank, and
such assignee, such assignee shall be a party to this Note and shall have all of
the rights and obligations of the Bank hereunder (and under any and all other
guaranties, documents, instruments and agreements executed in connection
herewith) to the extent that such rights and obligations have been assigned by
the Bank pursuant to the assignment documentation between the Bank and such
assignee, and the Bank shall be released from its obligations hereunder and
thereunder to a corresponding extent.  The Bank may furnish any information
concerning the Borrower in its possession from time to time to prospective
assignees, provided that the Bank shall require any such prospective assignees
to agree in writing to maintain the confidentiality of such information.

  16. The Borrower shall pay on demand all expenses of the Bank in connection
with the preparation, administration, demand, collection, waiver or amendment of
loan terms, or in connection with the Bank's exercise, preservation or
enforcement of any of its rights, remedies or options hereunder, including,
without limitation, fees of outside legal counsel or the allocated costs of in-
house legal counsel, accounting, consulting, brokerage or other similar
professional fees or expenses, and any fees or expenses associated with travel
or other costs relating to any appraisals or examinations conducted in
connection with the loan or any collateral therefor, and the amount of all such
expenses shall, until paid, bear interest at the rate applicable to principal
hereunder (including any default rate) and be an obligation secured by any

secondarily liable, to the acceptance of partial payments thereon and the

waiver of such right or any other right.  A waiver on any one occasion shall not
be construed as a bar to or waiver of any right on any future occasion.  All
rights and remedies of the Bank hereunder, under any document, instrument or
agreement evidencing, governing or securing this Note or under all applicable
laws shall be cumulative and may be exercised singularly or concurrently.

  (c) The provisions of this Note shall bind the successors and assigns of the

unenforceable, then only such provision shall be deemed ineffective and the
remainder of this Note shall not be affected.
