                                    RECITALS

                  A. The Borrower, the Banks and the Agent are parties to a
Credit Agreement dated as of July 23, 1996, as amended by a First Amendment
dated as of October 11, 1996, a Second Amendment dated as of September 26, 1997,
a Third Amendment dated as of March 20, 1998, a Fourth Amendment dated as of
July 23, 1998, a Fifth Amendment dated as of September 28, 1998 and a Sixth
Amendment dated as of October 21, 1998 (as so amended, the "Credit Agreement").

                  B. The parties hereto desire to amend the Credit Agreement in
certain respects and to waive certain Events of Default.

                  C. The Borrower has formed or acquired three new Subsidiaries,
namely, Norstan Consulting Holding Company, Norstan Consulting, Inc. and Norstan
Canada, Ltd., each of which Subsidiaries is required by the terms of the Credit
Agreement to become a Guarantor of the Borrower's obligations under the Credit
Agreement.

                  D. Effective, January 1, 1999, Connect Computer Corporation,
Vadini, Inc. d/b/a Prima Consulting, Inc. and Wordlink, Inc. were merged with
and into Norstan Consulting, Inc.

                  E. The operations of Norstan Canada, Inc. ceased as of April
30, 1999 and the assets thereof were transferred to Norstan Canada, Ltd. as of
May 1, 1999.

                  NOW, THEREFORE, in consideration of the premises and for other
good and valuable consideration the receipt and adequacy of which are hereby
acknowledged, the parties hereto hereby agree as follows:

                  Section 1. DEFINITIONS. Capitalized terms used herein and not
otherwise defined herein, but which are defined in the Credit Agreement, shall
have the meanings ascribed to such terms in the Credit Agreement unless the
context otherwise requires.

                  Section 2. AMENDMENTS TO CREDIT AGREEMENT. Subject to Section
5 hereof, the Credit Agreement is hereby amended as follows:

                  (a) Article IV thereof is amended by adding thereto the
following new Section 4.20:



                  Section 4.20 YEAR 2000. The Borrower has reviewed and assessed
         its business operations and computer systems and applications to
         address the "year 2000 problem" (that is, that computer applications
         and equipment used by the Borrower, directly or indirectly through
         third parties, may be unable to properly perform date-sensitive
         functions before, during and after January 1, 2000). The Borrower
         reasonably believes that the year 2000 problem will not result in a
         material adverse change in the Borrower's business condition (financial
         or otherwise), operations, properties or prospects or ability to repay
         the Bank. The Borrower is in the process of implementing a plan to
         remediate year 2000 problems and will complete implementation of such
         plan with respect to any material year 2000 problems, and testing
         thereof, by September 30, 1999. The Borrower agrees that this
         representation will be true and correct on and shall be deemed made by
         the Borrower on each date the Borrower requests any Advance under this
         Agreement or the Note or delivers any information to the Bank. The
         Borrower will promptly deliver to the Bank such information relating to
         this representation and covenant as the Bank may request from time to
         time.

                  (b) Section 6.5 thereof is amended to read as follows:

                  Section 6.5 SUBSIDIARIES. After the date of this Agreement,
         the Borrower will not, and will not permit any Subsidiary to, form or
         acquire any corporation which would thereby become a Subsidiary, unless
         (a) 100% of the issued and outstanding capital stock of such Subsidiary
         is owned by Norstan, Inc. or by a 100%-owned Subsidiary of Norstan,
         Inc., (b) each line of business of such Subsidiary is within the
         communications and information technology industries and (c) the
         aggregate amount of the Borrower's Investment or Investments in all
         such Subsidiaries shall not exceed the amounts set forth in Section
         6.10(l); provided, however, that Norstan Communications, Inc. shall be
         permitted to acquire the initial 75% of the membership interest in
         Connaissance contemplated by the Connaissance Agreement and on May 1,
         2001, to acquire the remaining 25% of the membership interest in
         Connaissance in accordance with the Connaissance Agreement and to
         invest an additional $200,000 in Connaissance for the sole purpose of
         acquiring certain assets of ASP Consulting; and provided, further, that
         the Borrower shall be permitted to acquire 100% of the issued and
         outstanding capital stock of Wordlink, Inc. notwithstanding the
         Borrower's failure to comply with clauses (iii) and (iv) of Section
         6.10(l) at the time of such acquisition.

                  (c) Section 6.8 thereof is amended to read as follows:

                  Section 6.8 CAPITAL EXPENDITURES. The Borrower will not, and
         will not permit any Subsidiary to, make Capital Expenditures in an
         amount exceeding, on a consolidated basis in any fiscal year, an amount
         equal to (a) seven percent (7%) of the consolidated revenues of the
         Borrower and the Subsidiaries as reported in their consolidated
         financial statements for the preceding fiscal year, PLUS (b) for the
         fiscal year ending April 30, 1998 only, Capital Expenditures
         attributable to the PRIMA Acquisition, plus (c) Capital

                                     - 2 -



         Expenditures attributable to the acquisition of membership interests in
         Connaissance pursuant to the Connaissance Agreement and the $200,000
         Investment in Connaissance for the purpose of acquiring certain assets
         of ASP Consulting, as permitted under Section 6.5.

                  (d) Section 6.10(k) thereof is amended to read as follows:

                  6.10(k) Loans and advances (i) by the Borrower to Norstan
         Communications, Inc., Norstan Network Services, Inc., Norstan
         Consulting, Inc. (with respect to Connect Computer Company, PRIMA and
         Wordlink, Inc., all of which were merged with and into Norstan
         Consulting, Inc. effective January 1, 1999), Norstan-UK, Norstan
         International and Connaissance and (for purposes other than to finance
         lease account receivables, as specified in 6.10(j) above) to Norstan
         Canada, and (ii) by Norstan Communications, Inc. to Connaissance as
         contemplated by the Connaissance Agreement, provided that, prior to the
         Borrower's acquisition of the remaining 25% membership interest in
         Connaissance pursuant to the Connaissance Agreement, the aggregate
         amount of such loans and advances to Connaissance shall not exceed
         $4,000,000 at any time outstanding prior to April 30, 2000 and
         $3,000,000 at any time outstanding on or after April 30, 2000.

                  (e) Section 6.16 thereof is amended to read as follows:

                  Section 6.16 MINIMUM EBITDA. The Borrower will not permit
         EBITDA to be less than (a) $9,000,000 for the period of one fiscal
         quarter ending April 30, 1999, (b) $16,000,000 for the period of two
         consecutive fiscal quarters ending July 31, 1999, (c) $26,000,000 for
         the period of three consecutive fiscal quarters ending October 31,
         1999, (d) $35,000,000 for the period of four consecutive fiscal
         quarters ending January 31, 2000 and (e) $40,000,000 for each period of
         four consecutive fiscal quarters ending on or after April 30, 2000.

                  (f) Section 6.19 thereof is amended to read as follows:

                  Section 6.19 INTEREST COVERAGE RATIO. The Borrower will not
         permit the Interest Coverage Ratio to be less than (a) 6.0 to 1.0 as of
         April 30, 1999, July 31, 1999 and October 31, 1999 and (b) 8.0 to 1.0
         as of January 31, 2000 and as of the last day of any fiscal quarter
         ending thereafter.

                  Section 3. WAIVER. The Borrower has informed the Banks that it
was not in compliance with its covenant under Section 6.10(k)(ii) hereof as
constituted prior to the date hereof, in that the aggregate outstanding
principal of loans and advances from Norstan Communications, Inc. to
Connaissance was in excess of $2,000,000, and that it was not in compliance with
its covenant under Section 6.16 of the Credit Agreement for the period ended
January 31, 1999, in that its actual EBITDA for the period of four consecutive
fiscal quarters ended on that date was less than $35,000,000. Each such instance
of noncompliance constitutes an Event of Default under the Credit Agreement.
Upon satisfaction of the conditions set forth in

                                     - 3 -



Section 5 of this Amendment, the Banks hereby waive the Events of Default
under the Credit Agreement described in the preceding sentences. This waiver
is limited to the express terms hereof and shall not extend to any other
Default, Event of Default or any other period. This waiver shall not be and
shall not be deemed to be a course of dealing upon which the Borrower may
rely with respect to any other Default, Event of Default or request for a
waiver and the Borrower hereby expressly waives any such claim.

                  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
