discretion (if it is capable of effecting a cure), within thirty (30)the
requisite time period after receipt of notice, and in such event, notice of
termination shall be ineffective. Recovery by the curing Party from the
breaching Party shall be governed by the Dispute Resolution procedures set forth
in this Agreement.

      10.3 Effects of Termination. Upon expiration or termination, all licenses
granted hereunder shall terminate unless such licenses are expressly stated as

amounts, shall survive any expiration or termination.

SECTION 11. CONFIDENTIAL INFORMATION

      11.1 The parties acknowledge and agree that the terms of this Agreement
and all information provided to or in connection with either Party's performance
under this Agreement shall be considered confidential and proprietary
information ("Confidential Information") and shall not be disclosed to any third
party without the prior written consent of the Party providing the Confidential
Information (the "Disclosing Party"). Confidential Information shall include,
without limitation: (i) names, addresses, and demographic, behavioral, and
credit information relating to Users or potential Users; (ii) Stockwalk's
communication materials and issuance strategies or methods; (iii) each Party's
trade secrets, including but not limited to, financial business objectives,
assets and properties, processes, formulas, specifications, programs,
instructions, source code, technical know-how, methods and procedures for

operation, benchmark test results, information about employees, customers,
strategies, services, business or technical plans and proposals in any form; and
(iv) programming techniques and technical, development, cost and processing
information.

      11.2 The Party receiving such Confidential Information (the "Receiving
Party") shall use Confidential Information only for the purpose of performing
the terms of this Agreement and shall not accumulate in any way or make use of
Confidential Information for any other purpose. The Receiving Party shall ensure
that only its employees, authorized agents, or subcontractors who need to know
Confidential Information to perform this Agreement will receive Confidential
Information and that such persons agree to be bound by the provisions of this
Paragraph and maintain the existence of this Agreement and the nature of their
obligations hereunder strictly confidential.

      11.3 The obligations with respect to Confidential Information shall not
apply to Confidential Information that: (i) either Party or its personnel
already know at the time it is disclosed as shown by


                                       9
<PAGE>

their written records; (ii) is publicly known without breach of this Agreement;
(iii) either Party received from a third party authorized to disclose it without
restriction; (iv) either Party, its agents or subcontractors, developed
independently without use of Confidential information; or (v) either Party is
required by law, regulation or valid court or governmental agency order or
request to disclose, in which case the Party receiving such an order or request,
to the extent practicable, must give notice to the other Party, allowing them to
seek a protective order.

      11.4 Each Party agrees that any unauthorized use or disclosure of
Confidential Information may cause immediate and irreparable harm to the
Disclosing Party for which money damages may not constitute an adequate remedy.
In that event, each Party agrees that injunctive relief may be warranted in
addition to any other remedies the Disclosing Party may have. In addition, the
Receiving Party agrees promptly to advise the Disclosing Party in writing of any
unauthorized misappropriation, disclosure or use by any person of the
Confidential Information which may come to its attention and to take all steps
at its own expense reasonably requested by the Disclosing Party to limit, stop
or otherwise remedy such misappropriation, disclosure or use.

      11.5 Upon either Party's demand, or upon the termination of this
Agreement, the Parties shall comply with each other's reasonable instructions
regarding the dispositions of Confidential Information, which may include return
of any and all Confidential Information (including any copies or reproductions
thereof). Such compliance shall be certified in writing, including a statement
that no copies of confidential information have been kept.

      11.6 Except as necessary for its performance under this Agreement, a Party
shall not use the name of any other Party or its Affiliates in connection with
any representation, publication or advertisement, or make any public statement
relating to any other Party or its Affiliates without the prior full disclosure
of same to the named Party, and the prior written consent of the named Party.

      11.7 Except as may be required by law, regulation or any governmental
authority, no Party nor any of its Affiliates shall issue a press release or
make public announcement or any disclosure to any third party related to the
transactions contemplated by this Agreement without the prior consent of each
other Party, which consent shall not be unreasonably withheld or delayed.

      11.8 The obligations of Sections 11.1 through 11.5 shall survive the
termination of this Agreement for a period of two (2) years.

SECTION 12. DISPUTE RESOLUTION

      12.1 In all discussions and activities relating to this Agreement, the
Parties will cooperate in good faith to accomplish the objectives specified in
this Agreement. If any dispute arises relating to either Party's rights or
obligations under this Agreement, and the Parties are unable to resolve the
dispute in the ordinary course of business, the Parties will use good-faith
efforts to resolve the matter by informal means, as set forth in Section 12.2
prior to commencing a formal dispute resolution proceeding or legal action in
accordance with this Section.

      12.2 Any controversy or claim between or among the Parties, arising from
or in connection with this Agreement whether based on contract, tort, common
law, equity, statute, regulation, order or otherwise ("Dispute") shall be
resolved as follows:

      (a) Upon written request of any Party, a duly appointed representative(s)
of each Party will meet for the purpose of attempting to resolve such Dispute.
Should they be unable to resolve the Dispute,


                                       10
<PAGE>

a senior executive of each Party (the "Executives") will meet in an effort to
resolve the Dispute. Said meeting shall be in person or by telephone.

      (b) The Executives shall meet as often as the Parties agree to discuss the
problem in an effort to resolve the Dispute without the necessity of any formal
proceeding.

      (c) Formal proceedings for the resolution of a Dispute may not be
commenced until the earlier of:

            (i) the Parties concluding in good faith that amicable resolution
      through the procedures set forth in subsections (a) - (b) hereof does not
      appear likely; or

            (ii) the expiration of the fifteen (15) business day period
      immediately following the initial request to negotiate the Dispute;

provided, however, that this Section 12.2 will not be construed to prevent a
Party from instituting formal proceedings earlier to avoid the expiration of any
applicable limitations period, to preserve a superior position with respect to
other creditors, or to seek temporary or preliminary injunctive relief.

SECTION 13. DISCLAIMERS, LIMITATIONS AND RESERVATIONS.

      13.1 EXCEPT AS EXPRESSLY PROVIDED IN THIS AGREEMENT, THE PARTIES HERETO DO
NOT MAKE, AND HEREBY DISCLAIM, ANY REPRESENTATIONS OR WARRANTIES REGARDING THE

TERM, AND (B) ANY ECONOMIC OR OTHER BENEFIT THAT THE OTHER PARTY HERETO MIGHT

enter into any agreement on the other's behalf of or in the other's name.

<PAGE>

      14.2 Press Release. Following the execution of this Agreement, the
Parties will prepare and distribute a joint press release (or coordinated press
releases) announcing the transaction. The contents and timing of the release (or
releases) shall be as mutually agreed by the Parties. Neither Party will issue
any further press releases or make any other disclosures regarding this
Agreement or its terms without the other Party's prior written consent.

      14.3 Compliance With Law. In its performance of this Agreement, each Party
will comply with all applicable laws, regulations, orders and other
requirements, now or hereafter in effect, of governmental authorities having
jurisdiction. Without limiting the generality of the foregoing, each Party will

compensation, royalties or transactions under this Agreement. At its own
expense, Stockwalk shall comply with all applicable laws and governmental and
SRO regulations regarding providing and operating the Stockwalk Services.

efforts to (a) obtain all governmental and SRO approval, permits and licenses,
and make all governmental and SRO filings and registrations, necessary for the

jurisdiction, and (b) promptly resolve any assertions that the Stockwalk or
Company's services are illegal or violating a protected third party interest.

      14.4 Notices. Notices deliverable under this Agreement shall be given in
writing, addressed to the Parties and shall be deemed to have been given either
one (1) day after being given to an express overnight carrier with a reliable
system for tracking delivery; or when sent by a confirmed facsimile with another
copy sent by any other mains specified in this paragraph; or three (3) business
days after having been mailed postage prepaid by United States registered or
certified mail.

      14.5 Attorneys Fees. If any litigation or arbitration is commenced to
enforce any provision of this Agreement or to seek a declaration of rights of
the Parties hereunder or as a result of any breach of any provisions of this
Agreement, the prevailing Party will be entitled to recover from the
non-prevailing Party all of its costs and expenses incurred in connection with
such litigation, including without limitation reasonable attorneys' fees.

      14.6 Records: Audits. Each Party shall keep detailed records of all
activities reasonably relating to its performance under this Agreement
("Records"). Either Party (the "Auditing Party"), upon thirty (30) days' prior
written notice to the other Party (the "Audited Party"), may conduct an audit of
the Audited Party's Records for the purpose of verifying the accuracy and
completeness of any report or other information provided by the Audited Party
under this Agreement. Any such audit will be conducted (a) in a manner that will
not unreasonably interfere with the Audited Party's operations, and (b) by an
independent certified public accounting firm that is reasonably acceptable to
the Audited Party and that has agreed in writing to protect the confidentiality
of the Audited Party's Records and other information. A Party may conduct an
audit under this Section no more than once during any 12-month period. The costs
of any such audit will be borne by the Auditing Party; provided however, that if
any audit determines that the report or other information subject to the audit
is inaccurate or incomplete by greater than ten percent (10%) (as measured by an
appropriate measure reasonably determined by the auditor), the Audited Party
will promptly reimburse the Auditing Party for all reasonable expenses incurred
to conduct the audit.

      14.7 Force Majeure. No Party will be liable for, or will be considered to
be in breach of or default under this Agreement on account of, any delay or
failure to perform as required by this Agreement as a result of any causes or
conditions that are beyond such Party's reasonable control and that such Party
is unable to overcome through the exercise of commercially reasonable diligence.
If any force majeure event occurs, the affected Party will give prompt written
notice to the other Party and will use commercially reasonable efforts to
minimize the impact of the event. However, if a force majeure event


                                       12
<PAGE>

detrimentally affects a Party's performance of a material covenant set forth in
Section 3 and Exhibit A for ten (10) days or more, the other Patty can terminate
this Agreement, as provided in Section 10.2 above.

      14.8 Assignment. This Agreement may not be assigned, in whole or in part,
by either Party or by operation of law, (including an assignment to (a) any
corporation resulting from any merger, consolidation or other reorganization
involving the assigning Part. (b) any of its Affiliates, or (c) any individual
or entity to which the assigning Party may transfer substantially all of its
assets; provided that the assignee agrees in writing to be bound by all the
terms and conditions of this Agreement) unless the other Party consents to the
assignment, which consent shall not be unreasonably withheld or delayed. Subject
to the foregoing, this Agreement will be binding on and enforceable by the
Parties and their respective successors and permitted assigns. Notwithstanding
the foregoing, either Party hereto may assign this Agreement to (a), (b) or (c)
provided.

      14.9 No Waiver. The failure of either Party to enforce any provision of
this Agreement will not constitute a waiver of the Party's rights to
subsequently enforce the provision. The remedies specified in this Agreement are
in addition to any other remedies that may be available at law or in equity.

      14.10 Severability. If any provision of this Agreement is declared null,
void or otherwise unenforceable, such provision will be deemed to have been
severed from this Agreement to the minimal extent if necessary, which Agreement
will otherwise be and remain in full force and effect to its remaining
provisions.

      14.11 Integration. This Agreement (a) represents the entire agreement
between the Parties with respect to the subject matter hereof and supersedes any
previous or contemporaneous oral or written agreements regarding such subject
matter and (b) may be amended or modified only by a written instrument signed by
a duly authorized agent of each Party.

      14.12 Choice of Law. This Agreement will be interpreted, construed and
enforced in all respects in accordance with the laws of the State of Minnesota
