                                 --------------------

WHEREAS, Millennium Dynamics, Inc. has developed and is the owner of certain
computer software programs it desires to license to the Customer; and

WHEREAS, the Customer desires to license such programs from Millennium Dynamics,
Inc.

NOW, THEREFORE, in consideration of the mutual terms and conditions set forth
herein, the parties agree hereto as follows:

1.  DEFINITIONS.
    -----------

For purposes of this Agreement, the following terms shall have the meanings set
forth below:

1.1  Confidential Information -- "Confidential Information" means the Software
     ------------------------
     (as defined herein) and all information disclosed to the Customer about
     Millennium Dynamics, Inc.'s marketing strategy, business practices,
     customers, finances, products, software, computer programs, services,
     methods and processes. "Confidential Information" also includes any and all
     information which this Agreement provides shall be deemed to be
     Confidential Information.

1.2  Agreement. -- This "Agreement" shall mean and include this document, all
     ----------

     this document or added to it by amendment or incorporated herein by

2.  GRANT.
    -----

Subject to the terms and conditions of this Agreement Millennium Dynamics, Inc.
hereby grants to the Customer a nonexclusive right to use the object code
version of each computer program listed on the Software Schedule attached hereto
and incorporated herein by reference and all manuals, instructions,
documentation coding sheets and other documents or information relating thereto
(collectively, the "Software") at the computer site(s) and on the CPU(s)
indicated for such programs on the Software Schedule.  This license is for the
designated CPU(s) at the designated site.  The Customer has no right to copy any
of the Software, except for purposes of system backup.  On any backup copy of
the Software, the Customer shall reproduce all original copyright notices and
claims of confidentiality, proprietary rights or trade secret.  This license
grants to the Customer the right to use the Software on another CPU at another
site for disaster recovery purposes. This license to use the Software for
disaster recovery purposes shall continue for so long as the disaster at the
designated CPU and/or site exists.  The Customer acknowledges that the Software
may not operate on a new CPU without modification to the mechanism that
identifies the specific CPU on which the Software is installed.  This license
also grants to the Customer the right to concurrently use the Software on
another CPU at another site for the limited purpose of disaster recovery
testing.

At no additional cost to the Customer, the Customer may transfer the Software
from the designated CPU at the designated site to a replacement CPU and/or a
replacement site, provided (i) that the replacement CPU is owned or leased by
the Customer and/or the replacement site is owned or leased by the Customer,
(ii) the Customer deinstalls the Software from the original designated CPU,
(iii) the Software is operated on only the replacement CPU, (iv) the Customer
provides Millennium Dynamics, Inc. at least thirty (30) days advanced written
notice of such transfer and provides Millennium Dynamics, Inc. the required
information about the replacement CPU and/or replacement site, and (v) the
operating system of the replacement CPU is MVS.  The Customer and Millennium
Dynamics, Inc. shall confirm the transfer of the Software from the designated
CPU at the designated site to a replacement CPU and/or a replacement site by
execution of an Amended Software Schedule to this Agreement.  The provisions of
this paragraph are based on the assumption that the transfer of the Software
from the designated CPU at the designated site to a replacement CPU and/or
replacement site is not part of an outsourcing of services by the Customer to a
third party or service bureau.  If an outsourcing of services to a third party
or service bureau does occur, the Customer and Millennium Dynamics, Inc. will
need to agree upon amended terms to this Agreement.


3.  LIMITS ON USE.
    -------------

The Customer shall use the Software for the Customer's internal purposes only
for its own business purposes and shall not use the Software for the benefit of
or to provide services to any third party or unaffiliated organization.  Without
limiting the generality of the foregoing restriction, the Customer shall not use
any of the Software to perform data processing services or service bureau
activities for a third party or an unaffiliated

                                      -2-
<PAGE>

organization. The license granted to Customer hereunder does permit the Customer
to use the Software for the benefit of any of the Customer's business divisions
and the Customer's affiliates, so long as such use is on the designated CPU(s)
at the designated site identified on the Software Schedule. For purposes of this
Agreement the term "affiliate" shall mean any entity that is controlled by,
under common control with, or controls the Customer. The parties will execute
Software Schedules to indicate the designated CPU(s) and the designated sites,
including any logical partitions of the designated CPU(s).

4.  TAXES.
    -----

If Millennium Dynamics, Inc. or the Customer is required to pay any sales, use,
export, import, excise or other taxes (whether federal, state, local or
otherwise) imposed with respect to this Agreement or any of the transactions
contemplated hereby, such taxes shall be paid by the Customer or the Customer
shall reimburse Millennium Dynamics, Inc. for any such taxes paid by Millennium
Dynamics, Inc.  Taxes based on Millennium Dynamics, Inc.'s net income and
Millennium Dynamics, Inc.'s franchise taxes shall be the sole responsibility of
Millennium Dynamics, Inc.

5.  ADDITIONAL SITES OR CPU(S).
    --------------------------

New sites or CPU(s) other than those listed on the Software Schedule will
require an amendment to the Software Schedule.


6.  CONFIDENTIALITY AND OWNERSHIP.
    -----------------------------

The Software and all derivatives and modifications thereof (including ones made
by or for the Customer) shall at all times be and remain the property of
Millennium Dynamics, Inc., and the Customer shall have no rights thereto except
as explicitly provided elsewhere in this Agreement.  The Software and all
derivatives and modifications thereof shall be deemed to be Confidential
Information of Millennium Dynamics, Inc. and shall be subject to the terms and
provisions of this Agreement which govern Confidential Information.

6.1  General. -- The Customer will keep confidential, will use only for the
     --------
     Customer's benefit as expressly permitted elsewhere in this Agreement and
     will not disclose to others without Millennium Dynamics, Inc.'s prior
     written approval, all Confidential Information.

6.2  Limited Access. -- The Customer shall limit access to Confidential
     ---------------
     Information to those employees who require such access in order to permit
     the Customer to use the Confidential Information as expressly permitted
     elsewhere in this Agreement in furtherance of the Customer's business.

6.3  Best Efforts. -- The Customer shall take all reasonable precautions to
     -------------
     maintain the confidentiality of all Confidential Information.  Without
     limiting the generality of the foregoing, the Customer shall employ

<PAGE>

     Information which are no less stringent than those employed by the Customer
     to protect its own confidential and proprietary information and/or trade
     secrets.

6.4  Return or Destruction. -- If at any time the Customer has in its possession
     ----------------------
     or under its control one or more copies (whether partial or complete) of
     any Confidential Information which the Customer does not at such time,
     pursuant to the terms of this Agreement, have the right to use at the
     designated site(s) and/or on the designated CPU(s), then the Customer shall
     (without the requirement of any notice or demand from Millennium Dynamics,
     Inc.) either deliver to Millennium Dynamics, Inc. or destroy all such
     copies, whether partial or whole and regardless of form. If the Customer
     elects to destroy such copies, it agrees to notify Millennium Dynamics,
     Inc. promptly that such copies have been destroyed.

6.5  Customer Confidential Information -- It is acknowledged and agreed that
     ---------------------------------
     Millennium Dynamics, Inc. will have access to confidential and proprietary
     information relating to the Customer's business and systems. Millennium
     Dynamics, Inc. will keep confidential all such information and will take
     all reasonable precautions to maintain the confidentiality of such
     information. Without limiting the generality of the foregoing, Millennium
     Dynamics, Inc. will employ precautions for the protection of such
     information which are no less stringent than those employed by Millennium
     Dynamics, Inc. to protect its own confidential and proprietary information
     and trade secrets.

EXCEPT AS EXPLICITLY PROVIDED ELSEWHERE IN THIS AGREEMENT, ALL INFORMATION,

     defects in materials and faulty workmanship at the time of shipment by
     Millennium Dynamics, Inc.  If any defect exists at the time of shipment
     which is detected within ninety (90) days of the time of shipment, then the
     defective item will be replaced by Millennium Dynamics, Inc. at no charge
     to the Customer.  THIS WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES ON THE

     MILLENNIUM DYNAMICS, INC. BE LIABLE FOR ANY SPECIAL, INDIRECT, INCIDENTAL
     OR CONSEQUENTIAL DAMAGES ARISING FROM ANY DEFECTS IN THE MAGNETIC MEDIA.

8.3  Software. -- For each program listed on the Software Schedule, subject to
     ---------
     the limitations of liability contained in this Agreement, Millennium
     Dynamics, Inc. warrants that such program (as delivered to the Customer and
     when used by the Customer without modification for its intended purpose and
     in accordance with this Agreement) (i) does not and will not infringe,
     violate or invade any United States copyright, trade secret, patent, or
     other proprietary right of any third party, (ii) so long as such program is
     supported by Millennium Dynamics, Inc. and unmodified by the Customer and
     used in accordance with this Agreement, it will operate substantially as
     specified within the product description manual, and (iii) the Software is
     free from computer viruses on the day of delivery by Millennium Dynamics,
     Inc. to the Customer. EXCEPT FOR THE FOREGOING WARRANTIES OF NON-

     THE SOFTWARE IS PROVIDED "AS IS", WITHOUT ANY EXPRESS OR IMPLIED WARRANTIES

     MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

     "Computer Virus" means any inappropriate computer instructions that alter,
     destroy, or inhibit the Software and/or the Customer's processing
     environment.  A Computer Virus includes, but is not limited to, a program
     that self replicates without manual intervention and instruction programmed
     to activate at a predetermined time or upon a specific event, and/or a
     program purporting to do a meaningful function but designed for a different
     function.  In the event a Computer Virus is contained in the Software
     delivered to the Customer, Millennium Dynamics, Inc.'s only obligation is
     to send to the Customer another copy of the Software to correct any
     Computer Virus problems.

     OR IN CONNECTION WITH THE SOFTWARE, INCLUDING, WITHOUT LIMITATION, LOSS OF
     ANTICIPATED PROFITS OR LOSS RESULTING FROM BUSINESS DISRUPTION, EVEN IF
     MILLENNIUM DYNAMICS, INC. HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
     DAMAGES.  IN NO EVENT SHALL THE LIABILITY OF MILLENNIUM DYNAMICS, INC. FOR
     DAMAGES ARISING OUT OF OR IN CONNECTION WITH THE USE OR PERFORMANCE OF THE
     SOFTWARE (UNDER ANY CONTRACT, TORT OR OTHER THEORY) EXCEED THE AMOUNT OF
     $225,000.00.

8.5  Correction of Errors. -- The Customer understands and accepts the risk that
     ---------------------
     errors may exist or occur in the Software, and agrees that no such error
     will be deemed to violate the warranty contained in subpart (ii) of Section
     8.3 of this Agreement, provided Millennium Dynamics, Inc. diligently
     investigates and attempts to correct such error after the Customer reports
     it to Millennium Dynamics, Inc.  Without limiting the generality of the
     foregoing, the Customer accepts responsibility for testing the accuracy of
     any and all conversion generated by the Software and agrees that in the
     event of any error, Millennium Dynamics, Inc. shall have no liability for

8.6  Indemnification. -- Millennium Dynamics, Inc. agrees to indemnify and hold
     ----------------
     harmless the Customer from all costs, expenses (including reasonable
     attorneys' fees), losses, liabilities, damages, and settlements arising out
     of or in connection with any claim or suit based on allegations which, if
     true, would constitute a breach of the warranty of non-infringement
     contained in subpart (i) of Section 8.3 of this Agreement.  The limitations
     of liability set forth in this Agreement shall not apply to the obligations
     of Millennium Dynamics, Inc. under this Section 8.6.

     8.6.1  Notice. -- The Customer shall as soon as practicable, notify
            -------
            Millennium Dynamics, Inc. in writing of any claim or suit which
            might give rise to a claim for indemnification by Millennium
            Dynamics, Inc. hereunder.

     8.6.2  Defense. -- In the event of such a claim or suit, Millennium
            --------
            Dynamics, Inc. will employ counsel for the defense and settlement
            thereof, shall file proper pleadings in said suit within the time

            developments.  If the suit is brought to trial, Millennium Dynamics,

                                      -6-
<PAGE>

     subpart (i) of Section 8.3 of this Agreement with respect to one of the
     program(s) listed on the Software Schedule, is brought or threatened
     against either Millennium Dynamics, Inc. or the Customer, then Millennium
     Dynamics, Inc. shall have the right, at its option and expense, to do any
     one or more of the following:

     8.7.1  Obtain for the Customer the right to continue using such program or
            a modified version thereof;

     8.7.2  Replace all or part of such program with a non-infringing program,
            or

     8.7.3  Terminate the license granted to the Customer with respect to such
            program and refund to the Customer an amount equal to the
            unamortized portion of the license fees paid to Millennium Dynamics,
            Inc. by the Customer in connection with such program. For these
            purposes, license fees shall be amortized on a straight line method
            over five years; thus, the unamortized portion of an license fee
            would be equal to the greater of (a) zero and (b) the initial
            license fee divided by 5, then divide that quotient by 12, and
            multiply that quotient by the difference between 60 and the number
            of months since the license fee was received by Millennium Dynamics,
            Inc. (for example, if the license is terminated after twelve (12)
            months, 6,000 (divided by) 5 = 1,200; 1,200 (divided by) 12 = 100;
            100 x (60 - 12) = $4,800).


9.  MAINTENANCE.
    -----------

9.1  Error Correction. -- So long as Millennium Dynamics, Inc. continues to
     -----------------
     support the programs listed on the Software Schedule, Millennium Dynamics,
     Inc. agrees to diligently investigate and attempt to correct any error in
     such programs reported to Millennium Dynamics, Inc. by the Customer and
     determined by Millennium Dynamics, Inc. to be an error in such programs or
     in the operating procedures recommended by Millennium Dynamics, Inc.  Such
     services shall be provided as a part of "Maintenance" described below.

     However, if Millennium Dynamics, Inc. determines that any error reported by
     the Customer is not an error in such programs or operating procedures, the
     Customer promptly shall pay Millennium Dynamics, Inc. for its services in
     investigating and/or correcting such error at Millennium Dynamics, Inc.'s
     then current consulting fees and shall reimburse Millennium Dynamics, Inc.
     for reasonable travel and living costs incurred in connection with such
     services.

9.2  Updates and Related Products.  -- For each program listed on the Software
     -----------------------------
     Schedule, Millennium Dynamics, Inc. may from time to time, at Millennium
     Dynamics, Inc.'s option, develop and distribute a new version or revision
     of such program (an "Update") or a new product which is related to such
     program and may in fact be a derivative of such program (a "Related
     Product").  In general, a program which simply corrects errors or enhances
     the existing features and functions of a

                                      -7-
<PAGE>

     program is an Update, while one which adds new functions and features is a
     Related Product. Whenever there is any question whether a particular
     program is an Update or a Related Product, Millennium Dynamics, Inc. shall
     make a determination which shall be binding upon both Millennium Dynamics,
     Inc. and the Customer.

     Millennium Dynamics, Inc. shall provide to the Customer, for the
     maintenance fees identified on the Software Schedule, all Updates to all
     programs listed on the Software Schedule (herein referred to as
     "Maintenance").  All Updates provided to the Customer hereunder shall be
     deemed to be Software and Confidential Information and shall be subject to
     the provisions of this Agreement.  The Customer will be contractually
     obligated to maintain the Software based on the most recent version that
     Millennium Dynamics, Inc. releases.  Failure by the Customer to do so will
     release Millennium Dynamics, Inc. of any warranty or performance liability
     hereunder.  Millennium Dynamics, Inc. shall offer to the Customer, for
     additional fees to be determined by Millennium Dynamics, Inc. at the time
     of the offering, the option to add any Related Product to the Software
     Schedule.

     The Customer shall be responsible for the installation of all Updates and
     any Related Product, unless otherwise agreed upon by the parties upon
     mutually acceptable terms.  If the Customer requests that Millennium
     Dynamics, Inc. perform installation, then the Customer shall pay Millennium
     Dynamics, Inc. for such services at Millennium Dynamics, Inc.'s then
     current consulting rates and shall reimburse Millennium Dynamics, Inc. for
     reasonable travel and living expenses.

9.3  Maintenance Fees. -- The Customer shall receive Maintenance at no charge.
     ----------------
     The first year of Maintenance shall commence on the effective date of this
     Agreement and shall terminate automatically on the day before the first
     anniversary of the effective date of this Agreement.  The second year and
     each year thereafter of Maintenance shall be calculated in the same manner.

9.4  Limited Warranties. -- Millennium Dynamics, Inc. shall perform all
     ------------------
     maintenance services hereunder in a proper and workmanlike manner in
     accordance with industry standards.  The preceding warranty granted by
     Millennium Dynamics, Inc. herein for Maintenance is a limited warranty
     only.  The parties agree that the Maintenance and related limited liability
     warranty consist of a contract for services and are not covered by Article
     II of the Uniform Commercial Code.  THIS WARRANTY IS IN LIEU OF ALL OTHER
     WARRANTIES, WHETHER EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, ANY
     IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE,
     ALL OF WHICH ARE EXPRESSLY DISCLAIMED. IN NO EVENT SHALL MILLENNIUM
     DYNAMICS, INC. BE LIABLE (UNDER ANY CONTRACT, TORT, OR OTHER THEORY) FOR
     ANY SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES ARISING FROM
     THE PERFORMANCE OF THIS AGREEMENT OR IN CONNECTION WITH MAINTENANCE,
     INCLUDING, WITHOUT LIMITATION, LOSS OF ANTICIPATED PROFITS OR LOSS
     RESULTING FROM BUSINESS

                                      -8-
<PAGE>

     DISRUPTION, EVEN IF MILLENNIUM DYNAMICS, INC. HAS BEEN ADVISED TO THE
     POSSIBILITY OF SUCH DAMAGES. IN NO EVENT SHALL THE LIABILITY OF MILLENNIUM
     DYNAMICS, INC. FOR DAMAGES ARISING OUT OF OR IN CONNECTION WITH MAINTENANCE
     (UNDER ANY CONTRACT, TORT OR OTHER THEORY) EXCEED THE AMOUNT OF
     $225,000.00.

9.5  Unsupported Programs. -- If the Software Schedule indicates that a
     ---------------------
     particular program is unsupported, Millennium Dynamics, Inc. shall have no
     obligation to correct errors in such program.  If Millennium Dynamics, Inc.
     no longer wishes to support a program which is listed on the Software
     Schedule, then Millennium Dynamics, Inc. shall have the right to amend the
     Software Schedule to indicate that such program is unsupported in
     accordance with the following procedure:

     9.5.1  Millennium Dynamics, Inc. shall provide written notice to the
            Customer that the program will cease to be supported on a specified
            date (the "Cutoff Date") which must be at least six (6) months in
            the future;

     9.5.2  Until after the Cutoff Date, Millennium Dynamics, Inc. shall
            continue to support such program and the Customer shall continue to
            pay any fee(s) specified on the Software Schedule for such program;
            and

     9.5.3  On and after the Cutoff Date, the Software Schedule shall be amended
            to indicate that such program is unsupported. Millennium Dynamics,
            Inc. shall have no further obligation to correct errors in the
            Program, the warranty contained in subpart (ii) of Section 8.3 of
            this Agreement shall no longer be effective with respect to such
            program, and the Customer shall have the right to receive a copy of
            the source code for such program as provided in Section 9.6 of this
            Agreement.

9.6  Source Code. -- For any program listed on the Software Schedule, if
     ------------
     Millennium Dynamics, Inc. designates such program as unsupported, then the
     Customer shall have the right to receive upon demand a copy of the source
     code for such program subject to the following terms and conditions:

     9.6.1  The source code for such program shall be deemed to be Confidential
            Information of Millennium Dynamics, Inc. and shall be subject to the
            terms and provisions of the Agreement which govern Confidential
            Information;

     9.6.2  The Customer shall have a nonexclusive right to use the source code
            version of such program for the limited purpose of maintaining the
            object code version of such program so that it can be used by the
            Customer at the designated sites and on the designated CPU(s) listed
            on the Software Schedule.

     9.6.3  The source code for such program shall be deemed to be Software
            within the meaning of this Agreement.

9.7  Source Code Escrow.
     ------------------
