1.   DESCRIPTION OF EXISTING OBLIGATIONS: Among other Obligations which may be
owing by Borrowers to Bank, Borrowers are indebted to Bank pursuant to, among
other documents, a Loan and Security Agreement, dated April 19, 2000, as may be
amended from time to time, (the "Loan Agreement"). The Loan Agreement provides

principal amount of Four Million Five Hundred Thousand Dollars ($4,500,000) and
a Term Loan in the original principal amount of Seven Hundred Fifty Thousand
Dollars ($750,000). Defined terms used but not otherwise defined herein shall
have the same meanings as set forth in the Loan Agreement.

Hereinafter, all indebtedness owing by Borrower to Bank shall be referred to as
the "Obligations."

2.   DESCRIPTION OF COLLATERAL. Repayment of the Obligations is secured by the
Collateral, as described in the Loan Agreement, and the Pledged Collateral, as
described in that certain Stock Pledge Agreement, dated August 24, 2000, by and
between Kanbay International, Inc. and Bank (the "Pledge").

Hereinafter the above-described security documents together with all other
documents securing repayment of the Obligations shall be referred to as the
"Security Documents". Hereinafter, the Security Documents, together with all
other documents evidencing or securing the Obligations shall be referred to as
the "Existing Loan Documents".

3.   DESCRIPTION OF CHANGE IN TERMS.

     A.   MODIFICATION(S) TO LOAN AGREEMENT.

          1.   The following defined term under Section 13.1 entitled
               "Definitions" is hereby amended to read as follows:

               "Revolving Maturity Date" is April 20, 2002.

4.   CONSISTENT CHANGES. The Existing Loan Documents are hereby amended wherever
necessary to reflect the changes described above.

to the contrary, (i) that the definition of "Code", "UCC" or "Uniform Commercial
Code" as set forth in the Security Documents shall be deemed to mean and refer
to "the Uniform Commercial Code as adopted by the State of Illinois, as may be
amended and in effect from time to time and (ii) the Collateral is all assets of
the Borrower. In connection therewith, the Collateral shall include, without
limitation, the following categories of assets as defined in the Code: goods
(including inventory, equipment and any accessions thereto), instruments
(including promissory notes), documents, accounts (including

7.   CONTINUING VALIDITY. Borrower (and each Pledgor signing below) understands
and agrees that in modifying the existing Indebtedness, Bank is relying upon
Borrower's representations, warranties, and agreements, as set forth in the
Existing Loan Documents. Except as expressly modified pursuant to this Loan
Modification Agreement, the terms of the Existing Loan Documents remain
unchanged and in full force and effect. Bank's agreement to modifications to the
existing Obligations pursuant to this Loan Modification Agreement in no way
shall obligate Bank to make any future modifications to the Obligations. Nothing
in this Loan Modification Agreement shall constitute a satisfaction of the
Obligations. It is the intention of Bank and Borrower to retain as liable
parties all makers and endorsers of Existing Loan Documents, unless the party is
expressly released by Bank in writing. Unless expressly released herein, no
maker, endorser, or guarantor will be released by virtue of this Loan
Modification Agreement. The terms of this paragraph apply not only to this Loan
Modification Agreement, but also to all subsequent loan modification agreements.

     This Loan Modification Agreement is executed as of the date first written
above.
