       2.1    EMPLOYEE CENSUS. Attachment A attached hereto sets forth a list of
       the U.S. Ford Customs Employees to be seconded to Vastera as of the
       Effective Date, together with their base salary rate, any other targeted
       or mandatory cash compensation, including without limitation, bonus
       levels (based on 2000 target bonus range), job classification, FCG status
       (as defined below) and scheduled rotation date and social security number
       where applicable ("Seconded Employees"). The period during which Seconded
       Employees are seconded to Vastera is referred to as the "Assigned
       Period". During the Assigned Period, Ford shall make available to Vastera
       the services of the Seconded Employees, on a full-time or part-time
       basis.

       2.2    VASTERA EMPLOYMENT. Seconded Employees may resign employment with
       Ford according to Ford's policies. In the event of such resignation, Ford
       will cooperate with Vastera in searching for and identifying appropriate
       candidates for Vastera to hire to fill such positions. Vastera shall have
       the right to hire any Seconded Employee and Ford shall not interfere with
       Vastera's attempt to hire any Seconded Employee. If a Seconded Employee
       desires to accept Vastera's offer of employment, Ford shall terminate
       such employee on a date mutually agreed by the Parties. In such event,
       the Seconded Employee shall be removed from Attachment A on Vastera's
       hire date.

       2.3    REPATRIATION TO FORD. Except as provided below or in Section 4.2,
       prior to *, no Seconded Employee shall be repatriated to Ford. In the
       event that there is an advancement, promotional or other career
       development opportunity available for a Seconded Employee, and upon
       mutual agreement between the Parties, a Seconded Employee may be released
       from this Agreement and repatriated to Ford on a mutually agreeable date,
       and Attachment A shall be modified accordingly. Notwithstanding anything
       herein to the contrary, any Seconded Employee who is in the Ford College
       Graduate Program ("FCG") as of the Effective Date shall be repatriated to
       Ford on the scheduled rotation date and Attachment A shall be modified
       accordingly. Nothing herein contained shall preclude Vastera from making
       an offer of employment to a FCG. On or after *, if Ford wishes to remove
       a Seconded Employee from Attachment A for placement at Ford, Ford shall
       give Vastera prior written notice of its request for such removal
       whereupon Ford and Vastera shall meet in good faith to determine the
       timing of such removal after consideration of each Party's mutual needs,
       such as Vastera's ability to replace the Seconded Employee and the timing
       of Ford's placement opportunities. Once a date is mutually agreed, the
       Seconded Employee shall be removed from Attachment A on the date the
       Seconded Employee is repatriated to Ford.

       Attachment C. The Non-Disclosure and Confidentiality Agreement shall
       contain the same terms as are contained in the agreement that employees
       of Vastera are required to sign. In the event a U.S. Ford Customs
       Employee refuses to sign the Acknowledgment, Non-Disclosure and
       Confidentiality Agreement, the Parties shall discuss whether the U.S.
       Ford Customs Employee shall be seconded or continue to be seconded under
       the terms of this Agreement.

       5.     PAYROLL AND RELATED SERVICES. During the Assigned Period, Ford

                     claims arising out of a work accident while the Seconded
                     Employee was performing work for Vastera during the
                     Assigned Period;

              (v)    Reasonable and necessary travel and business related

       but not limited to, wage and hour, overtime, discrimination laws, and/or

       11.    STAFFING OF VASTERA FOREIGN AFFILIATES. In the event Vastera or an
Affiliate forms another Affiliate for the purpose of conducting the Business in
a country other than the United States ("Vastera Foreign Affiliate"), if
requested by Vastera, Ford agrees to use its commercially reasonable efforts to
cause any of its Affiliates that do business in the same country or region
("Ford Foreign Affiliates"), or where appropriate under national law, will
recommend to the Ford Foreign Affiliate, to enter into a secondment arrangement
with the Vastera Foreign Affiliate with respect to certain employees of the Ford
Foreign Affiliate who refuse offers of Vastera employment, on terms and
conditions substantially similar to the terms expressed in this Secondment
Agreement, modified only to reflect variances in local law. For purposes of
Section 7, REIMBURSEMENT, the per-employee Standard Monthly Group fringe cost
shall be determined with reference to Ford's Standard Group Monthly Fringe cost
with respect to such country, where applicable, or a comparable statement of
labor costs and expressed as a percentage of base monthly salary. For purposes

limited liability company, trust, or other entity directly or indirectly,

control with a Party.

       their employment agreements and by law. Under this Agreement, Ford agrees

       and in original works of authorship created by any of the Seconded
       Employees, during the period each is seconded and that relate to

       under license from Vastera in accordance with other agreements between
       the Parties. Ford further agrees to execute all assignment and other
       transfer documents as may be necessary to cause the above assignment of
       intellectual property rights to be legally formalized. All such documents
       shall be prepared by Vastera at Vastera's expense, and provided to Ford
       with at least thirty (30) days notice.

       12.2   FORD'S IP WARRANTY. Ford warrants that it has the right to make

       SHALL IN NO EVENT BE LIABLE TO VASTERA, ITS SUCCESSORS, OR A THIRD PARTY
       FOR ANY DAMAGES, WHETHER DIRECT OR INDIRECT, SPECIAL OR GENERAL,
       CONSEQUENTIAL OR INCIDENTAL, ARISING FROM ANY LOSS CLAIMED AS A RESULT OF
       VASTERA'S USE OF THE INTELLECTUAL PROPERTY RIGHTS ASSIGNED HEREUNDER .

       (B)    FORD MAKES NO WARRANTY OR REPRESENTATION THAT THE INTELLECTUAL
       PROPERTY RIGHTS ASSIGNED HEREUNDER CAN BE USED FOR ANY PARTICULAR
       FUNCTION OR THAT VASTERA HAS THE ABILITY TO USE THEM. FORD ASSUMES NO
       RESPONSIBILITY FOR THE SAFETY, QUALITY, DESIGN, SPECIFICATIONS,
       COMPLETENESS, ACCURACY OR OTHER CHARACTERISTICS OF THE PERFORMANCE,
       OUTPUT OR END PRODUCT RESULTING FROM THE USE OF THE INTELLECTUAL PROPERTY
       RIGHTS ASSIGNED HEREUNDER.

       (C)    EXCEPT TO THE EXTENT OF THE WARRANTY PROVIDED ABOVE, NOTHING
       CONTAINED HEREIN SHALL BE CONSTRUED AS CONFERRING BY IMPLICATION,
       ESTOPPEL OR OTHERWISE THE INDEMNIFICATION OF VASTERA BY FORD AGAINST ANY
       CLAIM OF INFRINGEMENT OF OTHER THIRD PARTY INTELLECTUAL PROPERTY RIGHTS,

       to hold it harmless from any and all damage, loss, claim, liability and
       expense (including without limitation, reasonable attorneys' fees and

       Ford) incurred or suffered by Ford arising out of (i) breach of any

       obligations hereunder with respect to third-party claims, the following
       procedures shall apply:

                     relating to any claim, but no later than ten (10) days
                     before the date on which any response to a complaint or
                     summons is due, the indemnitor shall notify the indemnitee
                     in writing if the indemnitor acknowledges its
                     responsibilities and obligations with respect to such
                     indemnification and elects to assume control of the defense
                     and settlement of that claim (a "Notice of Election").

              (b)    PROCEDURE FOLLOWING NOTICE OF ELECTION. If the indemnitor
                     delivers a Notice of Election relating to any claim within
                     the required notice period, the indemnitor shall be
                     entitled to have sole control over the defense and all
                     negotiations for the compromise or settlement of such
                     claim; provided that (i) the indemnitee shall be entitled
                     to participate in the defense of such claim and to employ
                     counsel at its own expense to assist in the handling of
                     such claim, and (ii) the indemnitor shall obtain the prior
                     written approval of the indemnitee before entering into any
                     settlement of such claim or ceasing to defend against such
                     claim. The indemnitor shall not be required to indemnify
                     the indemnitee for any amount paid or payable by the
                     indemnitee in the settlement of any claim for which the
                     indemnitor has delivered a timely Notice of Election if
                     such amount was agreed to without the written consent of
                     the indemnitor.

              (c)    PROCEDURE WHERE NO NOTICE OF ELECTION IS DELIVERED. If the
                     indemnitor does not deliver a Notice of Election relating
                     to any claim within the required notice period, the
                     indemnitee shall have the right to defend the claim in such
                     manner as it may deem appropriate, at the cost and expense
                     of the indemnitor. The indemnitor shall promptly reimburse
                     the indemnitee for all such costs and expenses.

       14.    DISPUTE RESOLUTION. If a dispute arises between the Parties
relating to this Agreement, the following procedure shall be implemented except
that either Party may seek injunctive relief from a court where appropriate in
order to maintain the status quo while this procedure is being followed:

       14.1   INITIAL MEETING. The Parties shall hold a meeting promptly,
       attended by persons with decision-making authority regarding the dispute,
       to attempt in good faith to negotiate a resolution of the dispute;
       provided, however, that no such meeting shall be deemed to vitiate or
       reduce the obligations and liabilities of the Parties or be deemed a
       waiver by a Party hereto of any remedies to which such Party would
       otherwise be entitled hereunder.

       14.2   MEDIATION. If within thirty (30) days after such meeting the
       Parties have not succeeded in negotiating a resolution of the dispute,
       they agree to submit the dispute to mediation in accordance with the
       then-current Model Procedure for

CONFIDENTIAL

                                       10


       Mediation of Business Disputes of the Center for Public Resources and to
       bear equally the costs of the mediation.

       14.3   APPOINTMENT OF MEDIATOR. The Parties will jointly appoint a
       mutually acceptable mediator, seeking assistance in such regard from the
       Center for Public Resources if they have been unable to agree upon such
       appointment within twenty (20) days from the conclusion of the
       negotiation period.

       14.4   ARBITRATION. The Parties agree to participate in good faith in the
       mediation and negotiations related thereto for a period of thirty (30)
       days . If the Parties are not successful in resolving the dispute through
       the mediation, then the Parties agree to submit the matter to binding
       arbitration or a private adjudicator.

       14.5   GENERAL PROCEDURE. Mediation or arbitration shall take place in
       Pittsburgh, Pennsylvania unless otherwise agreed by the Parties.
       Equitable remedies shall be available in any arbitration. Punitive or
       exemplary damages shall not be awarded. This Section is subject to the
       Federal Arbitration Act, 9 U.S.C.A. Section 1 ET SEQ.

       14.6   ARBITRATION PROCEDURE. In the event of arbitration, the Parties
       agree that the award of the arbitrator shall be (1) the sole and
       exclusive remedy between them regarding any claims, counterclaims, or
       issues presented to the arbitrator; (2) final and subject to no judicial
       review; and (3) made and shall promptly be payable in U.S. dollars free
       of any tax, deduction, or offset. The Parties further agree that any
       costs, fees, or taxes incident to enforcing the award shall, to the
       maximum extent permitted by law, be charged against the Party resisting
       such enforcement. The Parties hereto agree that judgment on the
       arbitration award may be entered and enforced in any court of competent
       jurisdiction. Each Party shall, except as otherwise provided herein, be
       responsible for its own costs, including legal fees, incurred in the
       course of any arbitration proceedings. The fees of the arbitrator shall
       be divided evenly between the Parties.

       15.    MISCELLANEOUS.

       15.1   FORCE MAJEURE. Either Party's delay or failure to perform (except
       for a Party's payment obligation) shall be excused for so long as, and to
       the extent that, it is prevented from performing any of its obligations
       under this Agreement, in whole or in part, as a result of delays caused
       by fire, flood, earthquake, elements of nature or acts of God, riots,
       civil disorders, rebellions or revolutions in any country, or any other
       cause beyond the reasonable control of such Party (a "Force Majeure
       Event"). The non-performing Party shall promptly notify the other Party
       of the circumstances causing its delay or failure to perform and of its
       plan and efforts to implement a workaround solution. For as long as such
       circumstances prevail, the Party whose performance is delayed or hindered
       shall continue to use reasonable efforts to minimize the length and
       effect of

                                       11


       delays and shall re-commence performance after the cessation of the Force
       Majeure Event.

       15.2   BINDING NATURE AND ASSIGNMENT. This Agreement shall be binding on
       the Parties hereto and their respective successors and assigns. Except as
       otherwise provided in this Agreement, neither Party shall assign this
       Agreement or delegate such Party's obligations hereunder without the
       prior written consent of the other, except that either Party may assign
       this Agreement without the consent of the other Party to an entity that
       acquires all, or substantially all, of the business of the assigning
       Party (provided that such entity is not a competitor of the other Party).

       15.3   ENTIRE AGREEMENT, AMENDMENT, WAIVER. This Agreement, including the
       Attachments referred to herein and attached hereto constitutes the entire
       agreement between the Parties with respect to the subject matter hereof
       and supersedes all prior agreements, whether written or oral, with
       respect to the subject matter contained in this Agreement. No amendment
       or modification or waiver of a breach of any term or condition of this
       Agreement shall be valid unless in a writing signed by each of the
       Parties. The failure of a Party to enforce, or the delay by either of
       them in enforcing, any of their respective rights under this Agreement
       will not be deemed a continuing waiver or a modification of any rights
       hereunder and a Party may, within the time provided by applicable law and
       consistent with the provisions of this Agreement, commence appropriate
       legal proceedings to enforce any or all of its rights.

       15.4   NOTICES. All notices, requests, demands, and determinations under
       this Agreement (other than routine operational communications), shall be
       in writing and shall be deemed duly given (i) when delivered by hand,
       (ii) one (1) day after being given to an express, overnight courier with
       a reliable system for tracking delivery, or (iii) six (6) calendar days
       after the day of mailing, when mailed by United States mail, registered
       or certified mail, return receipt requested, postage prepaid, and
