         initially the amount set opposite such Bank's name on Exhibit 1.1A
         hereto (as such Exhibit may from time to time be amended) as its
         Revolving Commitment Amount, but as the same may be from time to time
         reduced as provided in Exhibit 1.1A, Section 2.7(i) or Section 2.12.

         (b) ADDITIONAL DEFINITION. A new definition of "Commitment Condition"
is added to Section 1.1 of the Credit Agreement, in appropriate alphabetical

         Agent of a copy of a commitment, in form and substance satisfactory to
         the Majority Banks, signed by the Borrower and a lender satisfactory to
         the Majority Banks, obligating such lender to extend credit to the
         Borrower (subject only to normal due diligence and documentation
         conditions).

         (c) TERMINATION OF INTEREST OPTIONS. Section 2.4 of the Credit
Agreement is amended to read in its entirety as follows:

                  2.4 TERMINATION OF INTEREST OPTIONS. Notwithstanding anything
         to the contrary in this Agreement, effective as of June 30, 2000, (i)
         the Borrower shall no longer have the option to obtain Advances as, or
         to convert all or any portion of outstanding Advances into, Eurodollar
         Rate Advances or CD Rate Advances, (ii) all new Advances shall be
         obtained and maintained as Reference Rate Advances, and (iii) at the
         election of each Bank with respect to its Advances, either (x) all
         outstanding Eurodollar Rate Advances and CD Rate Advances of that Bank
         shall be converted to Reference Rate Advances, without any further
         action by the Borrower (in which case the electing Bank shall not
         request any compensation from the Borrower, pursuant to Section 2.24 of
         the Credit Agreement or otherwise, due to the conversion occurring
         prior to the last day of an Interest Period) or (y) each outstanding
         Eurodollar Rate Advance and CD Rate Advance shall be converted to a
         Reference Rate Advance on the last day of the relevant Interest Period.

         (d) REPAYMENT. The second sentence of Section 2.6 of the Credit
Agreement is amended to read in its entirety as follows:

         In addition, if at any time the Aggregate Revolving Outstandings exceed
         the Aggregate Revolving Commitment Amounts (including but not limited
         to any excess caused by a reduction in the Revolving Commitment Amounts
         pursuant to Exhibit 1.1A, Section 2.7(i) or Section 2.12 hereof), the
         Borrower shall repay the Revolving Notes in an aggregate amount equal
         to such excess, which prepayment shall be apportioned among

                                     - 2 -
<PAGE>

         the Banks' Revolving Notes in accordance with their respective
         Revolving Outstandings Percentages.

         (e) MANDATORY PREPAYMENTS. Section 2.7(i) of the Credit Agreement is
amended to read in its entirety as follows:

                  2.7(i) MANDATORY PREPAYMENTS; REDUCTIONS IN REVOLVING
         COMMITMENT AMOUNTS. On the date of the occurrence of any of the
         following events, the Borrower shall prepay the Revolving Loans in an
         aggregate amount of 100% of the Net Proceeds received in cash by the
         Borrower or any Subsidiary thereof as a result of any of the following
         events: (A) sales or other transfers of NFS Lease Accounts and Norstan
         Canada Lease Accounts, and the related leases and equipment that are
         authorized by Section 6.2(d) and (e); (B) sales of any assets of the
         Borrower or any Subsidiary, other than sales of inventory in the
         ordinary course of business (but this subsection 2.7(i)(B) does not
         authorize any such sales, which are subject to Section 6.2 hereof); and
         (C) any public or private sale or offering by the Borrower of its
         capital stock or debt securities. The Revolving Commitment Amounts
         specified on Exhibit 1.1A for each period including or beginning after
         the date of a payment pursuant to the preceding sentence shall be
         reduced, ratably, by the amount of any payments pursuant to the
         preceding sentence.

         (f) STANDBY LETTER OF CREDIT FACILITY. Section 2.8A of the Credit
Agreement is amended by deleting the phrase "Termination Date" and inserting the
phrase "June 30, 2000" in its place. The effect of this amendment is that the
Agent shall not be obligated to issue Standby Letters of Credit at the request
of the Borrower on or after June 30, 2000. Nothing in this Amendment affects the
rights or obligations of the Borrower, the Banks or the Administrative Agent
with respect to any Standby Letter of Credit issued prior to June 30, 2000.

         (g) ADDITIONAL COVENANTS. The following new Sections 5.15, 5.16, 5.17,
5.18 and 5.19 are added to the Credit Agreement immediately following Section
5.14 thereof:

                  Section 5.15 ADDITIONAL FINANCIAL REPORTING. The Borrower
         shall immediately begin efforts to develop the capability of providing
         weekly reports to the Banks, in form acceptable to the Banks in their
         sole discretion, including (a) a forecast of consolidated receipts and
         disbursements for the period of eight consecutive weeks, beginning with
         the week in which the forecast is delivered, together with a comparison
         of actual receipts and disbursements for the immediately preceding week
         to the most recently delivered forecast, and (b) a current,
         consolidated statement of all of the Borrower's and its Subsidiaries'
         accounts payable, accounts receivable, inventory and cash balances. If
         the Borrower is unable to produce such reports by or before July 19,
         2000, and if the Commitment Condition has not been satisfied as of that
         date, the Borrower will retain a financial consultant selected by the
         Borrower and acceptable to the Banks to assist the Borrower in
         developing the capability to provide such reports. Once the Borrower
         has

                                     - 3 -
<PAGE>

         developed the capability to provide such reports, it will deliver such
         reports to the Agent weekly on Tuesday of each week.

                  Section 5.16 VALUE MAXIMIZATION PLAN. The Borrower shall
         immediately engage an investment banking firm, selected by the Borrower
         and acceptable to the Banks, for the purpose of assisting the Borrower
         in evaluating its assets for possible dispositions, developing a
         disposition strategy to maximize the value of the assets to be disposed
         of, and (should the Borrower fail to repay the Obligations and
         terminate the Revolving Commitments prior to August 15, 2000) to
         implement that strategy.

                  Section 5.17 LANDLORD WAIVERS. At the request of the Agent,
         the Borrower shall undertake reasonable efforts to obtain the execution
         of landlord waivers in form and substance acceptable to the Agent by
         the lessor with respect to any of the Borrower's business premises
         (each, a "Lessor"), whereby each such Lessor would, among other things,
         acknowledge the security interest in favor of the Agent and the Banks
         in the Borrower's assets and agree to allow the Agent and the Banks to
         have access to the leased premises in order to enforce such security
         interest or protect such collateral. The foregoing obligations of the
         Borrower are in addition to its obligations under Section 8 of its
         Security Agreement.

                  Section 5.18 ADDITIONAL COLLATERAL. On or before the tenth
         Business Day after the Agent delivers a draft pledge agreement to the
         Borrower, the Borrower shall: (i) execute and deliver to the Agent a
         pledge agreement, in form and substance satisfactory to the Banks,
         granting the Banks a security interest in all shares of capital stock
         and other ownership interests in any Subsidiary owned by the Borrower
         (or 65% of such shares or interests, in the case of foreign
         Subsidiaries); (ii) cause each Subsidiary that owns any shares of
         capital stock or other ownership interests in any other Subsidiary to
         execute and deliver to the Agent a pledge agreement, in form and
         substance satisfactory to the Banks, granting the Banks a security
         interest in all such shares and other ownership interests (or 65% of
         such shares or interests, in the case of foreign Subsidiaries); (iii)
         deliver to the Agent the original of all certificates pledged pursuant
         to the foregoing clauses (i) and (ii), together with corresponding
         stock powers and financing statements; and (iv) deliver to the Agent
         the certificate of title for the 1967 Ford Mustang owned by the
         Borrower, together with such documents as the Agent may request to
         perfect the Banks' security interest in such vehicle.

                  Section 5.19 VIBES PROJECT. The Borrower shall limit the total
         expenditures on the "Vibes" project during the period beginning on July
         1, 2000 and ending on August 15, 2000 to $125,000, of which at least
         $45,000 will constitute salary costs for current employees of the
         Borrower and its Subsidiaries working on the "Vibes" project between
         external assignments.

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 Amendment, the "Forbearance Termination Date"
shall mean the earlier to occur of:

         (x) July 10, 2000, unless on or before that date the Borrower delivers
         to the Agent (i) the favorable opinion of counsel acceptable to the
         Agent regarding the due authorization and execution of this Tenth
         Amendment and opining that it, and the Credit Agreement as amended
         hereby, are the valid, binding and enforceable obligations of the
         Borrower, which opinion shall be in form and substance satisfactory to
         the Agent, and (ii) a copy of the resolutions of the Board of Directors
         of the Borrower ratifying the execution, delivery and performance by
         the Borrower of this Amendment and the other documents to be executed
         by the Borrower in connection therewith (the "Amendment Documents"),
         certified by its Secretary or an Assistant Secretary, together with a
         certificate of the Secretary or Assistant Secretary of the Borrower
         certifying as to the incumbency and the true signatures of the officers
         authorized to execute the Amendment Documents on behalf of the
         Borrower.;

         (y) August 15, 2000; or

         (z) the date on which any Event of Default, other than the Existing
         Defaults, 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). Neither any
prior waivers or forbearance periods granted by the Agent and the Banks, nor the
forbearance by the Banks and the Agent set forth herein:

         (x) shall constitute a waiver of or agreement to forbear with respect
         to any Default or Event of Default (if any) under any Loan Document,
         other than the forbearance expressly provided herein with respect to
         the Existing Defaults, or

         (y) shall be, or 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.

The Agent and the Banks specifically reserve the right to exercise each and
every remedy available to it as a consequence of the Existing Defaults
(following the expiration of the forbearance period provided herein) or any
other Default or Event of Default, in their sole and

                                     - 6 -
<PAGE>

absolute discretion. The Borrower expressly acknowledges that the Agent and the
Banks have no obligation to extend the forbearance period.

                  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:

                  (c) the execution, delivery and performance by the Borrower of
         the Amendment (i) have been duly authorized by all requisite corporate

                  (d) as of the date hereof, no Default or Event of Default has

         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

                  (g) the Borrower did not plan to incur or pay more than
         $125,000 in expenses on the "Vibes" project during the period from July
         1, 2000 through the end of the temporary forbearance period provided
         under Section 4 above, and at least $45,000 of such expenses will be
         for the salaries of current employees of the Borrower or its
         Subsidiaries who are working on the "Vibes" projects between external
         assignments.

         and substance satisfactory to the Agent.

Upon receipt of all of the foregoing, the Agent shall notify the Borrower and
the Banks that this Amendment has become effective (but the failure of the Agent
to give such notice shall not affect the validity of this Amendment or prevent
it from becoming effective), whereupon this Amendment shall become effective.
Without limiting the generality of the forgoing, upon the effectiveness of this
Amendment, the modifications to the "Applicable Margin" effected by the
amendments contained in Section 2(a) of this Amendment shall be applicable to
all Advances outstanding on the date of this Amendment and to all Advances made
on or after such date.

                  Section 6. REAFFIRMATION. Each party hereto affirms and
acknowledges that (a) the Credit Agreement as amended by this Amendment remains
in full force and effect in accordance with its terms and (b) all references to
the "Credit Agreement" or any similar term contained in

                                     - 8 -
<PAGE>

any other Loan Document shall be deemed to be references to the Credit Agreement
as amended hereby. The Borrower hereby confirms, ratifies, approves and
reaffirms each of the Loan Documents and agrees that each of the Loan Documents,
as amended hereby, remains in full force and effect. The execution and delivery
by the parties of this Amendment is not intended as a novation, discharge or
extinguishment of the Borrower's existing obligations under the Credit Agreement
or as a termination or release of the Agent's or the Banks' security interests
in the collateral under the Security Documents, all of which obligations and
security interests shall remain in full force and effect, subject to the
amendments effected by this Amendment. The Borrower acknowledges and agrees that
its obligations to the Agent and the Banks under the Credit Agreement exist and
are owing without offset, defense or counterclaim assertable by the Borrower
against the Agent or the Banks.

                  Section 7. GENERAL RELEASE. The Borrower hereby releases and
discharges the Agent and each Bank, and each of their officers, directors,
employees, agents and attorneys, from any and all claims, actions and
liabilities of any kind or nature that it or any one claiming through or under
the Borrower ever had or may now have, whether now known or hereafter
discovered, arising out of or in any way relating to: (i) any lending
relationship or loan commitment between the Agent, the Banks and the Borrower
prior to the date of this Amendment; (ii) the documents and transactions
described in the recitals hereof; or (iii) the negotiations preceding the
execution and delivery of this Amendment. The Borrower acknowledges and agrees
that it has received the advice of independent counsel selected by it, or the
opportunity to obtain such advice, before entering into this Amendment, and has
not relied upon the Lender or any of its officers, directors, employees, agents
or attorneys concerning any aspect of the transactions contemplated by this
Amendment.

                  Section 8. ERICSSON ACQUISITION. The Borrower has requested
that the Banks consent to the Borrowers acquisition of certain assets from
Ericsson BEES Group, as required by Section 6.10 of the Credit Agreement. The
Borrower acknowledges that (i) the Banks have not provided the requested
consent, (ii) the Banks have requested more information regarding the proposed
acquisition, and (iii) the Banks have no obligation to consent to the proposed
acquisition even if the requested information is provided, and will grant or
deny that consent in their sole discretion.

                  Section 9.  GENERAL.

                  (a) The Borrower agrees to reimburse the Agent upon demand for
         all reasonable expenses (including reasonable attorneys fees and legal
         expenses) incurred by the Agent in the preparation, negotiation and
         execution of this Amendment and any other document required to be
         furnished herewith, and to pay and save the Agent harmless from all
         liability for any stamp or other taxes which may be payable with
         respect to the execution or delivery of this Amendment, which
         obligations of the Borrower shall survive any termination of the Credit
         Agreement.

                  (b) This Amendment may be executed in as many counterparts as
         may be deemed necessary or convenient, and by the different parties
         hereto on separate counterparts, each of which, when so executed, shall
         be deemed an original but all such counterparts shall constitute but
         one and the same instrument. Transmission by telecopier of an executed
         counterpart of this Agreement shall be deemed to constitute due and
         sufficient delivery of such counterpart. Each party shall promptly
         deliver an executed original of any counterpart delivered by telecopier
         to the Agent; PROVIDED, HOWEVER that the failure by any party to so
         deliver an original counterpart shall not affect the sufficiency of a
         telecopied copy of such counterpart (and the fact that such telecopied
         copy constitutes the due and sufficient delivery of such counterpart)
         as provided in the previous sentence.

                  (c) Any provision of this Amendment which is prohibited or
         unenforceable in any jurisdiction shall, as to such jurisdiction, be
         ineffective to the extent of such prohibition or unenforceability
         without invalidating the remaining portions hereof or affecting the
         validity or enforceability of such provisions in any other
         jurisdiction.

                  (d) This Amendment shall be governed by, and construed in
         accordance with, the internal law, and not the law of conflicts, of the
         State of Minnesota, but giving effect to federal laws applicable to
         national banks.

                  (e) This Amendment shall be binding upon the Borrower, the
         Agent and the Banks and their respective successors and assigns, and
         shall inure to the benefit of the Borrower, the Agent and the Banks and
         the successors and assigns of the Agent and the Banks.

                  (f) THE BORROWER ACKNOWLEDGES THAT THE BANKS HAVE NOT
         COMMITTED, AND ARE NOT COMMITTING AT THIS TIME, TO FINANCE THE
         BORROWER'S LOAN REQUIREMENTS FOR ANY PERIOD AFTER, OR TO EXTEND THE
         FORBEARANCE PERIOD PROVIDED UNDER THIS AMENDMENT TO ANY DATE AFTER,
         AUGUST 15, 2000. ANY SUCH FUTURE LOAN OR LOANS, OR EXTENSION, MAY BE
         MADE SOLELY AT THE OPTION OF THE BANKS AND ON SUCH TERMS AND CONDITIONS
         AS THE BANKS MAY THEN REQUIRE. THE BORROWER UNDERSTANDS THAT NO PRIOR
         COURSE OF DEALING, NO USAGE OF TRADE, NO ORAL STATEMENTS OR
         COMMITTMENTS BY THE AGENT, THE BANKS OR THEIR EMPLOYEES OR OTHER AGENTS
         WILL BE DEEMED TO BE A COMMITTMENT BY THE BANKS TO LEND MONEY TO THE
         BORROWER OR TO ANY OTHER PERSON, OR TO EXTEND THE FORBEARANCE PERIOD,
         UNLESS THE SAME IS REDUCED TO WRITING AND SIGNED BY AN AUTHORIZED
         REPRESENTATIVE OF THE AGENT AND EACH BANK.

         THE UNDERSIGNED, BY EXECUTION HEREOF, ACKNOWLEDGES THAT: (I)

                                     - 10 -

THIS AMENDMENT CONTAINS A COMPLETE RELEASE OF CLAIMS AND WAIVERS OF CERTAIN
RIGHTS; (II) IT HAS READ AND UNDERSTOOD THIS AMENDMENT IN ITS ENTIRETY PRIOR TO
SIGNING AND FULLY AGREES TO EACH, ALL AND EVERY PROVISION HEREOF; AND (III) IT
HAS RECEIVED A COPY HEREOF.

         Mustang or any other titled vehicle.

                  Section 4. CONDITIONS TO EFFECTIVENESS OF THIS AMENDMENT. This
Amendment shall not become effective until, and shall become effective when,
each and every one of the following conditions shall have been satisfied:

                  (a) The Agent shall have received executed counterparts of
         this Amendment, duly executed by the Borrower and each of the Banks.

                  (b) The Agent shall have received from the Guarantors a
         Consent and Agreement of Guarantors in the form of Exhibit B hereto
         (the "Guarantor Agreements") duly completed and executed by each
         Guarantor.

                  (c) The Agent shall have received the favorable opinion of
         counsel, which opinion shall be in form and substance satisfactory to
         the Agent.

                  (d) The Agent shall have received a copy of the resolutions of
         the Board of Directors of the Borrower authorizing the execution,
         delivery and performance by the Borrower of this Amendment and the
         other documents to be executed by the Borrower in connection therewith
         (the "Amendment Documents"), certified by its Secretary or an Assistant
         Secretary, together with a certificate of the Secretary or Assistant
         Secretary of the Borrower certifying as to the incumbency and the true
         signatures of the officers authorized to execute the Amendment
         Documents on behalf of the Borrower.

Upon receipt of all of the foregoing, the Agent shall notify the Borrower and
the Banks that this Amendment has become effective (but the failure of the Agent

acknowledges that (a) the Credit Agreement as amended by this Amendment remains

Borrower hereby confirms, ratifies, approves and reaffirms each of the Loan
Documents and agrees that each of the Loan Documents, as amended hereby, remains
in full force and effect. The execution and delivery by the parties of this
Amendment is not intended as a novation, discharge or extinguishment of the
Borrower's existing obligations under the Credit Agreement or as a termination
or release of the Agent's or the Banks' security interests in the collateral

                                     - 3 -
<PAGE>

Amendment. The Borrower acknowledges and agrees that its obligations to the
Agent and the Banks under the Credit Agreement exist and are owing without
offset, defense or counterclaim assertable by the Borrower against the Agent or
the Banks.

                  Section 6. GENERAL RELEASE. The Borrower hereby releases and
discharges the Agent and each Bank, and each of their officers, directors,
employees, agents and attorneys, from any and all claims, actions and
liabilities of any kind or nature that it or any one claiming through or under
the Borrower ever had or may now have, whether now known or hereafter
discovered, arising out of or in any way relating to: (i) any lending
relationship or loan commitment between the Agent, the Banks and the Borrower
prior to the date of this Amendment; (ii) the documents and transactions
described in the recitals hereof; or (iii) the negotiations preceding the
execution and delivery of this Amendment. The Borrower acknowledges and agrees
that it has received the advice of independent counsel selected by it, or the
opportunity to obtain such advice, before entering into this Amendment, and has
not relied upon the Lender or any of its officers, directors, employees, agents
or attorneys concerning any aspect of the transactions contemplated by this
Amendment.

                  Section 7.  GENERAL.

                  (a) The Borrower agrees to reimburse the Agent upon demand for
         all reasonable expenses (including reasonable attorneys fees and legal
         expenses) incurred by the Agent in the preparation, negotiation and
         execution of this Amendment and any other document required to be
         furnished herewith, and to pay and save the Agent harmless from all
         liability for any stamp or other taxes which may be payable with
         respect to the execution or delivery of this Amendment, which
         obligations of the Borrower shall survive any termination of the Credit
         Agreement.

                  (b) This Amendment may be executed in as many counterparts as
         may be deemed necessary or convenient, and by the different parties
         hereto on separate counterparts, each of which, when so executed, shall
         be deemed an original but all such counterparts shall constitute but
         one and the same instrument. Transmission by telecopier of an executed
         counterpart of this Agreement shall be deemed to constitute due and
         sufficient delivery of such counterpart. Each party shall promptly
         deliver an executed original of any counterpart delivered by telecopier
         to the Agent; PROVIDED, HOWEVER that the failure by any party to so
         deliver an original counterpart shall not affect the sufficiency of a
         telecopied copy of such counterpart (and the fact that such telecopied
         copy constitutes the due and sufficient delivery of such counterpart)
         as provided in the previous sentence.

                  (c) Any provision of this Amendment which is prohibited or
         unenforceable in any jurisdiction shall, as to such jurisdiction, be
         ineffective to the extent of such

                                     - 4 -

         prohibition or unenforceability without invalidating the remaining
         portions hereof or affecting the validity or enforceability of such
         provisions in any other jurisdiction.

                  (d) This Amendment shall be governed by, and construed in
         accordance with, the internal law, and not the law of conflicts, of the
         State of Minnesota, but giving effect to federal laws applicable to
         national banks.

                           (e) This Amendment shall be binding upon the
         Borrower, the Agent and the Banks and their respective successors and
         assigns, and shall inure to the benefit of the Borrower, the Agent and
         the Banks and the successors and assigns of the Agent and the Banks.

                  (f) THE BORROWER ACKNOWLEDGES THAT THE BANKS HAVE NOT
         COMMITTED, AND ARE NOT COMMITTING AT THIS TIME, TO FINANCE THE
         BORROWER'S LOAN REQUIREMENTS FOR ANY PERIOD AFTER, OR TO EXTEND THE
         FORBEARANCE PERIOD PROVIDED UNDER THE TENTH AMENDMENT TO ANY DATE
         AFTER, AUGUST 15, 2000. ANY SUCH FUTURE LOAN OR LOANS, OR EXTENSION,
         MAY BE MADE SOLELY AT THE OPTION OF THE BANKS AND ON SUCH TERMS AND
         CONDITIONS AS THE BANKS MAY THEN REQUIRE. THE BORROWER UNDERSTANDS THAT
         NO PRIOR COURSE OF DEALING, NO USAGE OF TRADE, NO ORAL STATEMENTS OR
         COMMITTMENTS BY THE AGENT, THE BANKS OR THEIR EMPLOYEES OR OTHER AGENTS
         WILL BE DEEMED TO BE A COMMITTMENT BY THE BANKS TO LEND MONEY TO THE
         BORROWER OR TO ANY OTHER PERSON, OR TO EXTEND THE FORBEARANCE PERIOD,
         UNLESS THE SAME IS REDUCED TO WRITING AND SIGNED BY AN AUTHORIZED
         REPRESENTATIVE OF THE AGENT AND EACH BANK.

         THE UNDERSIGNED, BY EXECUTION HEREOF, ACKNOWLEDGES THAT: (I) THIS
AMENDMENT CONTAINS A COMPLETE RELEASE OF CLAIMS AND WAIVERS OF CERTAIN RIGHTS;
(II) IT HAS READ AND UNDERSTOOD THIS AMENDMENT IN ITS ENTIRETY PRIOR TO SIGNING
AND FULLY AGREES TO EACH, ALL AND EVERY PROVISION HEREOF; AND (III) IT HAS
RECEIVED A COPY HEREOF.
