         that the aggregate outstanding principal of loans and advances as of
         such date from Norstan Communications, Inc. to Connaissance was in
         excess of $4,000,000;

                  (b) that it was not in compliance with its covenant under

<PAGE>

                  (e) that it was not in compliance with its covenant under
         Section 6.18 of the Credit Agreement for the period ended January 29,
         2000, in that the Adjusted Leverage Ratio as of that date was more than
         3.0;

                  (f) that it was not in compliance with its covenant under
         Section 6.19 of the Credit Agreement for the period ended January 29,
         2000, in that the Interest Coverage Ratio as of that date was less than

         $1,000,000 for such fiscal year.

Each such instance of noncompliance constitutes a Default or Event of Default
under the Credit Agreement (collectively, the "Existing Defaults"). Upon the
satisfaction of the conditions set forth in Section 5 below, each Bank and the
Agent shall, until the Forbearance Termination Date (defined below), forbear
from exercising its remedies under the Loan Documents arising from the Existing
Defaults. For purposes of this letter, the "Forbearance Termination Date" shall
mean the earlier to occur of May 12, 2000 or the date on which any additional
Event of Default occurs. The Banks' and the Agent's agreement to forbear is
limited to the express terms thereof, and nothing herein shall be deemed a
waiver or forbearance by the Banks or the Agent of any other term, condition,
representation or covenant applicable to the Borrower or any Guarantor under the
Loan Documents (including but not limited to any future occurrence similar to
the Existing Defaults). The forbearance by the Banks and the Agent set forth
herein shall not constitute a waiver or forbearance by the Banks or the Agent of
any other Default or Event of Default, if any, under any Loan Document, and
shall not be, and shall not be deemed to be, a course of action with respect
thereto upon which the Borrower may rely in the future, and the Borrower hereby
expressly waives any claim to such effect.

                  Section 4. REPRESENTATIONS AND WARRANTIES OF THE BORROWER. To
induce the Banks and the Agent to execute and deliver this Amendment (which
representations and warranties shall survive the execution and delivery of this
Amendment), the Borrower represents and warrants to the Agent and the Banks
that:

                  (a) this Amendment has been duly authorized, executed and
         delivered by it and this Amendment constitutes the legal, valid and
         binding obligation of the Borrower enforceable against the Borrower in

         which might result from bankruptcy, insolvency, reorganization,
         moratorium or similar laws or equitable principles relating to or
         limiting creditors' rights generally;

                  (b) the Credit Agreement, as amended by this Amendment,
         constitutes the legal, valid and binding obligation of the Borrower
         enforceable against the Borrower in accordance with its terms, subject

         the Amendment (i) have been duly authorized by all requisite corporate
         action and, if required, shareholder action, (ii) do not require the
         consent or approval of any governmental or regulatory body or agency,

         or regulation or its certificate of incorporation or bylaws, (2) any
         order of any court or any rule, regulation or order of any other agency
         or government binding upon it, or (3) any provision of any material
         indenture, agreement or other instrument to which it is a party or by
         which any of its properties or assets are or may be bound, or (B)
         result in a breach of or constitute (alone or with due notice or lapse
         of time or both) a default under any indenture, agreement or other
         instrument referred to in clause (iii)(A)(3) of this Section 4(c);

                  (d) as of the date hereof, no Default or Event of Default has
         occurred which either (a) is continuing or (b) pursuant to which the
         Agent and the Banks have not agreed to temporarily forbear from
         exercising their remedies as set forth in Section 3 of this Amendment;
         and

                  (e) all the representations and warranties contained in
         Article IV of the Credit Agreement are true and correct in all material
         respects with the same force and effect as if made by the Borrower on
         and as of the date hereof.

         counsel, which opinion shall be in form and substance satisfactory to
         the Agent.

Upon receipt of all of the foregoing, the Agent shall notify the Borrower and

to give such notice shall not affect the validity of this Amendment or prevent
it from becoming effective), whereupon this Amendment shall become effective as
