                                    default under, any of the Consulting Sale
                                    Collateral, or modify or amend, or waive any
                                    default under, any agreement with respect to
                                    the Consulting Sale Collateral, or consent
                                    to or acquiesce in any of the foregoing,
                                    without in each case the prior written

         pertaining to the Persus Collateral or any part thereof for any purpose
         not inconsistent with the terms of this Agreement or the Borrower's
         Security Agreement, provided, however, that the Borrower shall not
         exercise or refrain from exercising any such right if such action could
         reasonably be expected to be inconsistent with the terms of this
         Agreement or the Security Agreement, including without limitation,
         Pledgor's voting at any time to increase the number of member interests
         of authorized and/or issued member interests of Persus, except in a

         however, that any and all

                           (i) dividends and other distributions paid or payable
                  other than in cash in respect of, and instruments and other
                  property received, receivable or otherwise distributed in
                  respect of, or in exchange for, any Collateral,

                           (ii) dividends and other distributions paid or

                  connection with a reduction of capital, capital surplus or
                  paid-in-surplus, and

                           (iii) cash paid, payable or otherwise distributed in
                  redemption of, or in exchange for, any Collateral,

         shall be, and shall be forthwith delivered to the Bank to hold as,
         Collateral and shall, if received by the Borrower, be received in trust
         for the benefit of the Bank, be segregated from the other property or
         funds of the Borrower, and be forthwith delivered to the Bank as
         Collateral in the same form as so received (with any necessary
         indorsement or assignment). The Borrower shall, upon request by the
         Bank, promptly execute all such documents and do all such acts as may
         be necessary or desirable to give effect to the provisions of this
         Section 5.18(c).

                  (d) Upon the occurrence and during the continuance of any
         Event of Default, the Bank shall have the right in its sole discretion,
         and the Borrower shall execute and deliver all such proxies and other
         instruments as may be necessary or appropriate to give effect to such
         right, to terminate all rights of the Borrower to exercise or refrain
         from exercising the voting and other consensual rights that it would
         otherwise be entitled to exercise pursuant to Section 5.18(b) hereof,
         and all such rights shall thereupon become vested in the Bank who shall
         thereupon have the sole right to exercise or refrain from exercising
         such voting and other consensual rights; provided, however, that the
         Bank shall not be deemed to possess or have control over any voting
         rights with respect to any Collateral unless and until the Bank has
         given written notice to the Borrower that any further exercise of such
         voting rights by the Borrower is prohibited and that the Bank and/or
         its assigns will henceforth exercise such voting rights; and provided,
         further, that neither the registration of any item of Collateral in the
         Bank's name nor the exercise of any voting

                                      -5-
<PAGE>   6

         rights with respect thereto shall be deemed to constitute a retention
         by the Bank of any such Collateral in satisfaction of the Obligations
         or any part thereof.

                  (e) Upon the occurrence and during the continuance of any
         Event of Default:

                           (i) all rights of the Borrower to receive the
                  dividends and other distributions that it would otherwise be
                  authorized to receive and retain pursuant to Section 6(c)
                  hereof shall cease, and all such rights shall thereupon become
                  vested in the Bank who shall thereupon have the sole right to
                  receive and hold such dividends and other distributions as
                  Collateral under the Borrower's Security Agreement, and

                           (ii) all payments of dividends and other
                  distributions that are received by the Borrower contrary to
                  the provisions of paragraph (i) of this Section 5.18(e) shall
                  be received in trust for the benefit of the Bank, shall be
                  segregated from other funds of the Borrower and shall be
                  forthwith paid over to the Bank as Collateral under the
                  Borrower's Security Agreement in the same form as so received
                  (with any necessary indorsement).

                  (f) The Borrower agrees that it will not (i) sell, assign (by
         operation of law or otherwise) or otherwise dispose of, or grant any
         option with respect to, any of the Persus Collateral.

                  (g) The Pledgor agrees that it will (i) cause Persus not to
         issue any stock, member interests or other securities in addition to or
         in substitution for the Persus Collateral, except to the Pledgor and
         except for the 700 voting interests and 3750 nonvoting interests in
         Persus issued in favor of the "Partners", as specified in the Master
         Agreement and (ii) pledge under the Borrower's Security Agreement,
         immediately upon its acquisition (directly or indirectly) thereof, any
         and all additional member interests, stock or other securities of
         Persus issued in favor of the Borrower

                           (b) Notwithstanding whether an Event of Default has
                  occurred, any and all Net Proceeds paid, payable or otherwise
                  distributed in respect of, or in exchange for, any Consulting
                  Sale Collateral, shall be applied, and shall be forthwith
                  delivered to the Agent to apply, to the Obligations in the
                  manner set forth in Section 2.6(c) hereof and shall, if
                  received by the Borrower or any Subsidiary, be received in
                  trust for the benefit of the Agent, be segregated from the
                  other property or funds of the Borrower or such Subsidiary,
                  and be forthwith delivered to the Agent in the same form as so
                  received (with any necessary endorsement or assignment).
                  Notwithstanding the forgoing, upon the occurrence of an Event
                  of Default and at any time during the continuance thereof, the
                  Agent may take any action with respect to the Consulting Sale
                  Collateral specified in Section 20 of the Borrower's Security
                  Agreement or otherwise. Notwithstanding anything to the
                  contrary in the Borrower's Security Agreement, the Borrower
                  will not, without the Agent's prior written consent, agree to
                  any modifications,

                                      -6-

                  amendments, subordinations, cancellations or terminations of
                  the obligations of any Account Debtor (as defined in the
                  Borrower's Security Agreement) upon any Consulting Sale
                  Collateral. Within 10 days of any request therefor made by the
                  Agent from time to time, the Borrower shall furnish to the
                  Agent a written accounting of all amounts received on or prior
                  to the date of such request by the Borrower or any Subsidiary
                  upon the Consulting Sale Collateral and the Net Proceeds
                  derived therefrom, which accounting shall be certified by the
                  chief financial officer of the Borrower and shall be in form
                  and substance reasonably acceptable to the Agent.

                           (c) The provisions of this Section 5.18 shall
                  supplement, and be cumulative of, the Borrower's Security
                  Agreement.

                  (d) Investments. The following new Section 6.10(s) of the
         Credit Agreement is added immediately following Section 6.10(r) of the
         Credit Agreement:

                           (s) Investments comprising the Consulting Sale
                  Collateral.

                  (e) Events of Default. Section 7.1(c) of the Credit Agreement
         is amended by deleting the clause "5.15 or 5.16" as it appears therein
         and substituting in lieu thereof the clause "5.15, 5.16, 5.17 or 5.18".

         Section 3. Consent; Waiver of Events of Default; Termination of
Consulting Security Documents; Delivery of Instruments. Upon the satisfaction of
the conditions set forth in Section 5 below:

                  (a) Each Bank and the Agent (i) hereby consents to the
         execution and delivery by the Borrower of the Consulting Sale Agreement
         and the consummation of the transactions contemplated thereby, (ii)
         hereby waives any default or Event of Default arising under Sections
         4.10, 4.19, 6.1, 6.2, 6.10, 6.14, 7.1(k), 7.1(m) or 7.1(o) of the
         Credit Agreement due to the matters specified in the forgoing clause
         (i) and (iii) hereby waives any default or Event of Default arising
         under Section 5.17 of the Credit Agreement (as it existed prior to the
         date of this Amendment) arising due to the failure of the Borrower to
         timely furnish to the Agent the documents specified therein. The Banks'
         and the Agent's consents and waivers set forth in the forgoing sentence
         are limited to the specific terms thereof, and nothing herein shall be
         deemed a waiver 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 waivers by the Banks
         and the Agent set forth this subparagraph shall not constitute a waiver
         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.

                  (b) The following documents are each hereby terminated for all
         purposes: (i) the Guaranty of NCHC, (ii) the Pledge Agreement of NCHC,
         (iii) the Security

                                      -7-

         Agreement of NCHC, (iv) the Guaranty of Consulting and (v) the Security
         Agreement of Consulting

                  (c) Schedule I attached to the Borrower's Pledge Agreement is
         hereby amended to read as set forth on Exhibit A to this Amendment.
         Except as amended by this Amendment, the Borrower's Pledge Agreement
         shall remain unmodified and in full force and effect.

                  (d) The Agent shall execute and deliver to the Borrower's
         counsel the following: (i) UCC-3 financing statements terminating the
         UCC-1 financing statements filed by the Agent with respect to the
         Security Agreements executed by NCHC and Consulting and the Pledge
         Agreement executed by NCHC, (ii) UCC-3 financing statements amending
         the UCC-1 financing statement filed by the Agent with respect to the
         Borrower's Pledge Agreement to delete from the collateral description
         set forth therein the common stock of NCHC pledged by the Borrower
         thereunder, (iii) the share certificates representing the common stock
         of NCHC and Consulting held by the Agent and the corresponding stock
         powers held by the Agent.

         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

         limiting creditors' rights generally;

                  (b) the Credit Agreement, as amended by this Amendment,

                           Monthly Revolving Availability exceeds $10,000,000,
                           then, on or before the 10th calendar day of the next
                           following month, the Borrower shall prepay the Term A
                           Loan and Term B Loan in the amount of such excess.

                           Ratably to the unpaid installments upon the Term A
                           Loans and (b) second, Ratably to the unpaid
                           installments upon the Term B Loans.

                           such Borrowing Base Deficiency. Amounts paid on the
                           Revolving Loans under this Section 2.6(f) shall be
                           for the account of each Bank in proportion to its
                           share of outstanding Revolving Loans. If, after
                           paying all outstanding Revolving Loans, a Borrowing
                           Base Deficiency still exists, the Borrower shall pay

                           2002), the Borrower shall prepay the Term B Loans in
                           an amount equal to 50% of the Excess Cash Flow for
                           such fiscal year. Amounts paid on the Term B Loans
                           under this Section 2.6(g) shall applied to the unpaid
                           installments upon the Term B Loans in inverse order
                           of their maturities.

         Agreement is deleted in its entirety and the following is substituted

                           the Borrower from time to time prior to the
                           Termination Date in such amounts as the Borrower
                           shall request; provided, however, that:

                                    to exceed $8,000,000;

                                             (ii) No Additional Letter of Credit
                                    shall have a stated available amount of less

                                            (iii) Without the prior written
                                    consent of all of the Banks, no Additional
                                    Letter of Credit shall expire later than the
                                    earlier of (i) 365 days after the date of

                  Minneapolis time, on a Business Day which is not less than one
                  Business Day preceding the requested date of issuance (which
                  shall also be a Business Day). Each request for an Additional

                  Letter of Credit and after giving effect thereto the
                  applicable conditions specified in Article III have been and

                  made on such letter of credit application and reimbursement
                  agreement form as the Agent may from time to time specify,
                  along with satisfactory evidence of the authority and
                  incumbency of the officers of the Borrower making such
                  request. The Agent shall promptly notify the other Banks of
                  the receipt of the request and the matters specified therein.
                  On the date of each issuance of an Additional Letter of Credit
                  the Agent shall send notice to the other Banks of such
                  issuance, accompanied by a copy of the Additional Letter or
                  Letters of Credit so issued. Additional Letters of Credit
