<PAGE>

            4.1   Limitation on Acquiring Additional Stock. (a) Except as
otherwise provided in this Agreement, Ford agrees that from the closing date
of the IPO until July 1, 2004 (the "Market Standstill Period") under no
circumstance will it acquire additional shares of Vastera Common Stock if
such acquisition would cause the total number of shares held by Ford to
exceed twenty-seven and one half percent (27.5%) of Vastera's issued and
outstanding Common Stock (the "Market Standstill Percentage"), unless Ford
first receives the written consent of Vastera's Board of Directors; provided
that this obligation shall not apply to the acquisition by Ford of any shares
of Vastera common stock obtained pursuant to any dividend in kind
distribution or any other distribution or transaction which does not require
the payment of consideration by Ford.

            (b) If Ford breaches its market standstill obligation contained
in subsection 4.1(a) and as a result of such breach, Ford's holdings of
Vastera issued and outstanding Common Stock exceeds twenty-seven and one half
percent (27.5%) of the issued and outstanding Common Stock of Vastera but
does not exceed thirty percent (30.0%) of the same, then Vastera will have the
right but not the obligation to purchase such number of shares of Vastera
Common Stock held by Ford as will reduce Ford's ownership interest to
twenty-seven and one half percent (27.5%) of the then outstanding shares of
Vastera Common Stock (taking such purchase into effect). The price per share
to be paid by Vastera any time it exercises its purchase right hereunder
shall be the lesser of (i) the price at which Vastera first sells shares to
the public in connection with its IPO, as contained in Vastera's final
prospectus or (ii) the lowest price per share paid by Ford in any open market
or private sales transaction.

            (c) If Ford breaches its market standstill obligation contained
in subsection 4.1(a) and as a result of such breach, Ford's holdings of
Vastera issued and outstanding Common Stock exceeds thirty percent (30.0%) of
the issued and outstanding Common Stock of Vastera, then Vastera shall have
the right but not the obligation to purchase such number of shares of Vastera
Common Stock held by Ford as will reduce Ford's ownership interest to
twenty-five percent (25.0%) of the then outstanding shares of Vastera Common
Stock (taking such purchase into effect). The price per share to be paid by
Vastera any time it exercises its purchase right hereunder shall be the
lesser of (i) the price at which Vastera first sells shares to the public in
connection with its IPO, as contained in Vastera's final prospectus or (ii)
the lowest price per share paid by Ford in any open market or private sales
transaction.

            (d) Notwithstanding the market standstill provisions contained in
subsection 4.1(a) to the contrary, Vastera acknowledges that if, during the term
of the Market Standstill Period: (i) Vastera enters into an agreement with a
third party permitting such third party to acquire an ownership percentage that
exceeds Ford's Market Standstill Percentage, Ford's Market Standstill Percentage
will immediately be adjusted upward to equal that of such third party; and (ii)
if any third party, by way of direct purchase from Vastera, open market purchase
or any combination thereof acquires an ownership percentage that exceeds Ford's
Market Standstill Percentage, the terms and conditions of subsection 4.1(a)
shall immediately terminate and be of no further force or effect. In addition,
if Vastera breaches the terms and conditions of Related Agreements, the terms
and conditions of subsection 4.1(a) shall immediately terminate and be of no
further force or effect.

            4.2   Limitation on Sale of Shares. For so long as Ford holds at
least 10% of the Common Stock on a fully diluted basis, Ford will have the
right to sell the Shares pursuant to a registration statement only in
accordance with the following schedule: (i) up to 10% of the initial number
of Shares acquired pursuant to this Agreement (the "INITIAL SHARES") on or
after six (6) months following the closing date of the IPO ; (ii) up to 20%
of the Initial Shares on or after twelve (12) months following the closing
date of the IPO; (iii) up to 70% of the Initial Shares on or after
twenty-four (24) months following closing date of the IPO; (iv) up to 85% of
the Initial Shares on or after thirty-six (36) months following closing date
of the IPO; (v) no limitation on or after forty-eight (48) months following
the closing date of the IPO. The number of Shares that can be sold shall be
adjusted for any stock splits, stock dividends or other events affecting the
capitalization of Vastera.

            4.3.  Termination of Market Standstill and Limitations on Ford
Sales. If either (i) Vastera postpones or otherwise delays proceeding with its
IPO beyond the period ending 90 days after the Effective Date, and the reason or
reasons underlying Vastera's decision to postpone proceeding with such IPO are
not reasonably based upon market conditions and factors, or (ii) Vastera has not
consummated the initial sale of shares of its Common Stock pursuant to its IPO
within 18 months of the Effective Date (regardless of market conditions), then
the terms and conditions contained in clauses (iv) and (v) of subsection 4.2
shall terminate and Ford shall be entitled to sell 100% of the Initial Shares at
anytime following the second anniversary of the closing date of the IPO;
provided however, that if following termination of the terms and conditions of
clauses (iv) and (v) pursuant to this section 4.3(a), Ford desires to increase
its ownership percentage in Vastera above the Market Standstill Percentage then
in effect, then any offer by Ford to purchase issued and outstanding shares of
Vastera common stock must be extended to all of Vastera's stockholders that hold
issued and outstanding shares of Vastera common stock. If Ford does not extend
such offer to all such stockholders, then Ford shall remain bound by the terms
and conditions of Section 4.1.

            4.4.  Survival. The covenants contained in Subsections 4.1 and 4.2
shall survive the Closing.

            4.5   Breach of Representations and Warranties. Ford shall not take
any action that would breach or cause to be inaccurate any of the
representations and warranties set forth in Section 7. Promptly after becoming
aware of the occurrence of or the pending or threatened occurrence of any event
that would cause or constitute such a breach or inaccuracy, Ford shall give
detailed written notice thereof to Vastera and SSC and shall use its diligent
efforts to prevent or remedy such breach or inaccuracy promptly.

      5.    Covenants of SSC and Vastera.

                                       6
<PAGE>

            5.1.  Observer Rights. Upon the execution of this Agreement, Ford
shall have the right to designate one representative (the "FORD OBSERVER") who
shall have the right to (i) attend each meeting of the Board of Directors of
Vastera, (ii) receive all notices of the time and place of any such meeting in
the same manner and at the same time as notice is sent to the directors or
committee members and (iii) receive copies of all notices, reports, minutes,
consents and other documents at the time and in the manner as they are provided
to the Board of Directors of Vastera; provided however, such representative
shall have no right to call a vote, prevent a vote, or vote on matters presented
or discussed at any meetings of the Board of Directors of Vastera. The right of
Ford to designate the Ford Observer shall terminate in the event that Ford's
share of Vastera Common Stock is less than * of Vastera's total equity on a
fully diluted basis.

            5.2   Survival. The covenants contained in Subsection 5.1 shall
survive the Closing.

            5.3   Breach of Representations and Warranties. Vastera shall not
take any action that would breach or cause to be inaccurate any of the
representations and warranties set forth in Section 6. Promptly after becoming
aware of the occurrence of or the pending or threatened occurrence of any event
that would cause or constitute such a breach or inaccuracy, Vastera shall give
detailed written notice thereof to Ford and shall use its diligent efforts to
prevent or remedy such breach or inaccuracy promptly.

power and authority to enter into this Agreement and the Related Agreements to
which it is a party, to perform its obligations hereunder and thereunder, and to

<PAGE>

operations and cash flows for the fiscal years then ended, compiled by Vastera
(the "AUDITED FINANCIAL STATEMENTS") and (ii) a complete and correct copy of the
unaudited balance sheet of Vastera (the "STUB PERIOD BALANCE SHEET") as of March
31, 2000 (the "STUB PERIOD BALANCE SHEET Date") and the related statements of
operations and cash flows for the three-month periods then ended, compiled by

Financial Statements, the "FINANCIAL STATEMENTS"). The Financial Statements are

and present fairly the financial condition and results of operations of Vastera,
as of the dates and for the periods indicated. The Audited Financial Statements
have been prepared in accordance with generally accepted accounting principles,
consistently applied. The Stub Period Financial Statements have been prepared
for the internal use of management and may not be in accordance with generally
accepted accounting principles because of the absence of footnotes normally
contained therein and are subject to normal year-end audit adjustments which in

the ordinary course of business subsequent to the Stub Period Balance Sheet Date
which do not have, either in any individual case or in the aggregate, a material
adverse effect on Vastera's or its Subsidiaries' assets, liabilities, financial
condition, operation or prospects. Except as disclosed on Schedule 6.9, since
the Stub Period Balance Sheet Date, there has been no material adverse change in
the condition, financial or otherwise, net worth or results of operations of
Vastera and its Subsidiaries, other than changes occurring in the ordinary
course of business which changes have not, individually or in the aggregate, had
a material adverse effect on the business, prospects, properties or condition,
financial or otherwise, of Vastera.

            6.10  Agreements; Action. Except as set forth on Schedule 6.10,
there are no agreements, understandings, instruments, contracts, proposed
transactions, judgments, orders, writs or decrees to which Vastera or any of its
Subsidiaries is a party or, to its knowledge, is bound which may involve (i)

            6.11  Compliance. Each of Vastera and its Subsidiaries has, in all
material respects, complied with all laws, regulations and orders applicable to
its present and proposed business, except where the failure to be in compliance
with such laws, regulations or orders would not have a material adverse effect
on the business, operations or condition of Vastera or any of its Subsidiaries.
There is no term or provision of any material mortgage, indenture, contract,
agreement or instrument to which Vastera or any of its Subsidiaries is a party
or by which it is bound, or, to the best knowledge of Vastera, of any provision
of any state or Federal judgment, decree, order, statute, rule or regulation
applicable to or binding upon Vastera or any of its Subsidiaries, that
materially adversely affects or, so far as Vastera may now foresee, in the
future is reasonably likely to materially adversely affect, the business,
prospects, condition, affairs or operations of Vastera or any of its
Subsidiaries, properties or assets. To the best of the knowledge of Vastera, no
employee of Vastera or any of its Subsidiaries is in violation of any contract
or covenant (either with Vastera or with another entity) relating to employment,
patent, other proprietary information disclosure, non-competition, or
non-solicitation. Vastera and its Subsidiaries have all necessary permits,
licenses and other authorizations required to conduct their business as
conducted and Vastera and its Subsidiaries have been operating their business
pursuant to and in compliance with the terms of all such permits, licenses and
other authorizations, except where the failure to obtain such permit, license or
authorization or their non-compliance has not and could not reasonably be
expected to have a material adverse effect on the business operations or
conditions of Vastera and its Subsidiaries.

            6.12  Books and Records. The minute books of Vastera contain
complete and accurate records of all meetings and other corporate actions of its
stockholders and its Board of Directors and committees thereof. The stock ledger
of Vastera is complete and reflects all issuances, transfers, repurchases and
cancellations of shares of capital stock of Vastera.

            6.13  Litigation. Except as set forth in the attached Schedule 6.13
for all representations and warranties in this Section 6.13, there is no (i)
action, suit, claim, proceeding or investigation pending or, to the best of
Vastera's knowledge, threatened against or affecting Vastera or its
Subsidiaries, at law or in equity, or (ii) governmental inquiry pending or, to
the best of Vastera's knowledge, threatened against or affecting Vastera or its
Subsidiaries, and to the best of Vastera's knowledge there is no basis for any
of the foregoing. Neither Vastera nor any of its Subsidiaries is not in default
with respect to any order, writ, injunction or decree known to or served upon
Vastera or any of its Subsidiaries of any court or of any Federal, state,
municipal or other governmental department, commission, board, bureau, agency or
instrumentality, domestic or foreign. There is no action or suit by Vastera or
its Subsidiaries pending, threatened or contemplated against others.

            6.14  Patents, Trademarks, Etc. Each of Vastera and its Subsidiaries
owns or possesses licenses or other rights to use all intellectual property
necessary or desirable to the conduct of its business as conducted, and no claim
is pending or threatened to the effect that the operations of Vastera or any of
its Subsidiaries infringe

                                       11
<PAGE>

upon or conflict with the asserted rights of any other Person under any
intellectual property, and there is no basis for any such claim (whether or not
pending or threatened). No claim is pending or, to the best of Vastera's
knowledge, threatened to the effect that any such intellectual property owned or
licensed by Vastera or its Subsidiaries, or which Vastera or its Subsidiaries
otherwise have the right to use, is invalid or unenforceable by Vastera or any
of its Subsidiaries, and, to the best of Vastera's knowledge, there is no basis
for any such claim (whether or not pending or threatened).

            6.15  Taxes. Except as set forth in the attached Schedule 6.15,
Vastera and each of its Subsidiaries has filed all tax returns, Federal, state,
county and local, required to be filed by it, and each of Vastera and its
Subsidiaries has paid all taxes shown to be due by such returns as well as all
other taxes, assessments and governmental charges which have become due or
payable, including without limitation, all taxes which Vastera is obligated to
withhold from amounts owing to employees, creditors and third parties. Each of
Vastera and its Subsidiaries has established adequate reserves for all taxes
accrued but not yet payable. The Federal income tax returns of Vastera and each
of its Subsidiaries have never been audited by the Internal Revenue Service. No
deficiency assessment with respect to or proposed adjustment of Vastera's or any
of its Subsidiaries' Federal, state, county or local taxes is pending or, to the
best of Vastera's knowledge, threatened. There is no tax lien (other than for
current taxes not yet due and payable), whether imposed by any Federal, state,
county or local taxing authority, outstanding against the assets, properties or
business of Vastera or its Subsidiaries. Neither Vastera nor any of its present
or former stockholders has ever filed an election pursuant to Section 1362 of
the Internal Revenue Code of 1986, as amended, that Vastera be taxed as an S
corporation.

            6.16. Assets; Real Property.

            (a)   Except as set forth in the attached Schedule 6.16(a) Vastera
and each of its Subsidiaries has good and marketable title to, or a valid
leasehold interest in, the properties and assets used by it, located on its
premises or shown on The Financial Statements or acquired thereafter, free and
clear of all Encumbrances, except for properties and assets disposed of in the
ordinary course of business since the date of The Financial Statements and
except for Encumbrances disclosed on The Financial Statements and liens for
current property taxes not yet due and payable. Vastera and each of its
Subsidiaries owns, or has a valid leasehold interest in, all assets and
properties necessary for the conduct of its business as conducted.

            (b)   Neither Vastera nor any of its Subsidiaries has and never has
had, any ownership interest, security interest or other interest of any kind in
any real property whatsoever with the exception of real property leases for
office space.

            6.17. Contracts; No Defaults. Neither Vastera nor any of its
Subsidiaries is in default with respect to the performance of any of its
obligations under any agreements material to Vastera and its Subsidiaries,
including but not limited to,

                                       12
<PAGE>

employment agreements, agreements involving performance of services or delivery
of goods or materials to or by Vastera or its Subsidiaries, and each lease,
rental, license and conditional sale agreement affecting any real or personal
property used, owned or licensed by Vastera or its Subsidiaries, agreements
relating to intellectual property used, owned or licensed by Vastera or its
Subsidiaries, and other agreements to which Vastera or its Subsidiaries is a
party or is bound, in each case if the agreement involves the payment of
$100,000 or more in either a single payment or over a twelve-month period. Each
such agreement is in full force and effect and is valid and enforceable in
accordance with its terms.

            6.18. Employees. To the best knowledge of Vastera or SSC, no
executive or key employee of Vastera or any of its Subsidiaries or any group of
employees of Vastera or any of its Subsidiaries has any plans to terminate
employment with Vastera or any of its Subsidiaries. Neither Vastera or any of
its Subsidiaries, nor to the best of Vastera's knowledge, any of its employees
is subject to any noncompete, nondisclosure, confidentiality, employment,
consulting or similar agreements relating to, affecting or in conflict with the
present business activities of Vastera or any of its Subsidiaries. Neither
Vastera nor any of its Subsidiaries is a party to or bound by any collective
bargaining agreement, nor has it experienced any strikes, grievances, claims of
unfair labor practices or other collective bargaining disputes and no activity
or claims have been threatened.

            6.19. ERISA. Vastera's plans or trusts and the plans or trusts of
its Subsidiaries are all in compliance with ERISA and the Internal Revenue Code
of 1986.

            6.20. Offering. Subject to the truth of the representations and
warranties of Ford contained in Section 7 hereof, the transfer of the Shares is
exempt from the registration requirements of the Securities Act of 1933, as
amended.

            6.21. Related Party Transactions. Except as set forth in the
attached Schedule 6.21, no employee, officer or director of Vastera or any of
its Subsidiaries, or member of the immediate family of any of them, is indebted
to Vastera or any of its Subsidiaries, nor is Vastera or any of its Subsidiaries
indebted (or committed to make loans or extend or guarantee credit) to any of
them. No employee, officer or director of Vastera or any of its Subsidiaries, or
member of the immediate family of any of them, has any direct or indirect
ownership interest in any Person with which Vastera or any of its Subsidiaries
is affiliated or with which Vastera has a business relationship, or any Person
that competes with Vastera or any of its Subsidiaries. No employee, officer or
director of Vastera or any of its Subsidiaries, or member of the immediate
family of any of them, is, directly or indirectly, interested in any material
agreement with Vastera or any of its Subsidiaries.

            6.22  Disclosures. Neither this Agreement nor any exhibit hereto,
nor any report, certificate or instrument furnished to Ford in connection with
the transactions contemplated by this Agreement, when read together, contains or
will contain any material misstatement of fact or omits or will omit to state a
material fact necessary to

                                       13
<PAGE>

make the statements contained herein or therein not misleading. Vastera knows of
no information or fact that has or would have a material adverse effect on the
business, prospects or condition (financial or otherwise) of Vastera that has
not been disclosed to Ford in writing.

      7.    Representations and Warranties of Ford. Ford represents and warrants
to Vastera as follows, except as set forth on the attached disclosure schedules,
that:

            7.1   Organization; Good Standing; Power. Ford is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware.

            7.2   Authorization of Ford. Ford has full power and authority to
enter into this Agreement and the Related Agreements to which it is a party, to
perform its obligations hereunder and thereunder, and to consummate the
transactions contemplated hereby and thereby. Ford has taken all necessary and
appropriate corporate action with respect to the execution and delivery of this
Agreement and the Related Agreements. No other corporate proceedings on the part
of Ford are necessary to authorize this Agreement or to consummate the
transactions so contemplated hereby including approval by any creditors of Ford.
This Agreement and each Related Agreement constitutes valid and binding
obligations of Ford, enforceable in accordance with their terms except as
limited by applicable bankruptcy, insolvency, moratorium, reorganization, or
other laws affecting creditors' rights and remedies generally.

            7.3   Investment Intent. Ford is acquiring the Shares for its own
account for investment and not with a view to, or for sale or other disposition
in connection with, any distribution thereof, nor with any present intention of
selling or otherwise disposing of the same.

            7.4.  Investment Experience; Accredited Investor Status. Ford is an
informed and sophisticated investor, and has sufficient knowledge and experience
in business and financial matters to permit it to evaluate the merits and risks
of an investment in Vastera. Ford is an "accredited investor" as defined in
Regulation D promulgated under the Securities Act. Ford acknowledges that the
Shares are being issued and sold under exemptions from registration provided in
the Securities Act and under applicable state securities laws and, therefore,
cannot be sold unless subsequently registered under the Securities Act or
applicable state securities laws or an exemption from such registrations is
available. Accordingly, Ford represents and warrants that it is able to bear the
economic risk of any investment in the Shares.

            7.5.  Information. Ford represents that it has had the opportunity
to ask questions and receive answers concerning the Shares and to obtain
whatever information concerning Vastera as has been requested by Ford in order
to make its investment decision.

                                       14

            7.6   Conduct of Business. At all times, Ford has conducted the
Business diligently in the ordinary course thereof.

            7.7   Undisclosed Liabilities, Releases and Waivers. There are no
debts, liabilities or obligations with respect to which the assets of the
Business that are being acquired by SSC are subject, whether liquidated,
unliquidated, accrued, absolute, contingent, or otherwise other than in the
ordinary course of business.

            7.8   Compliance with Laws. To Ford's knowledge, Ford has complied
and is in compliance with all applicable foreign, federal, state, and local
laws, statutes, licensing requirements, rules, and regulations, and judicial or
administrative decisions applicable to the Business where the failure to so
comply could have a material adverse effect on the results of operations or
financial condition of the Business.

            7.9   Consents. Except for the requirements of the HSR Act or as set
forth on Schedule 7.9, no consent, approval, order or authorization of, or
registration, qualification, designation, declaration or filing with, any
governmental authority is required on the part of Ford in connection with (i)
the execution and delivery of this Agreement or (ii) the transactions to be
consummated at the Closing, as contemplated by this Agreement.

            7.10  Restrictive Documents or Orders. Ford is not a party to or
bound under any agreement, contract, order, judgment, writ, rule regulation or
decree, or any similar restriction not of general application which reasonably
could be expected to materially adversely affect, (i) the continued operation by
SSC of the Business after the Closing on substantially the same basis as the
Business was theretofore operated (assuming that SSC and Vastera have received
all requisite consents and are qualified and authorized to operate the Business
in each jurisdiction in which the nature of the Business requires it to be so
qualified), or (ii) the consummation of the transactions contemplated by this
Agreement.

            7.11  Absence of Change. Since March 31, 2000, there has been no
material adverse change in the condition of the Business, financial or
otherwise, other than changes occurring in the ordinary course of business which
changes have not, individually or in the aggregate, had a materially adverse
effect on the Business.

            7.12  Litigation. Except as set forth on Schedule 7.12, there is no
(i) action, suit, claim, proceeding or investigation pending or, to Ford's
knowledge, threatened against or affecting the operation of the Business by
Ford, at law or in equity, or (ii) governmental inquiry pending or, to Ford's
knowledge, threatened against or affecting the operation of the Business by
Ford. Ford is not in default with respect to any order, writ, injunction or
decree known to or served upon Ford relating to the Business of any court or of
any Federal, state, municipal or other governmental department, commission,
board, bureau, agency or instrumentality, domestic or foreign.

<PAGE>

            7.13  No Conflict or Default. Neither the execution and delivery of
this Agreement, nor compliance with the terms and provisions hereof and thereof,
including without limitation, the consummation of the transactions contemplated
hereby and thereby, will violate any statute, regulation, or ordinance of any
governmental authority, or conflict with or result in the breach of any term,
condition, or provision of its Articles of Incorporation or Bylaws, as presently
in effect, or of any agreement, deed, contract, mortgage, indenture, writ,
order, decree, legal obligation, or instrument to which Ford is a party or by
which it is or may be bound, or constitute a default (or an event which, with
the lapse of time or the giving of notice, or both, would constitute a default)
thereunder.

      8.    Survival of Representations and Warranties. Except as expressly
provided elsewhere herein, all representations and warranties contained herein
shall survive the execution and delivery of this Agreement and the closing of
the transactions contemplated hereby for a period of two years.

Business are attached hereto as Exhibit G. Ford makes no representations as to

      10.   Dispute Resolution. If a material breach occurs or a dispute arises
between the parties relating to this Agreement, the following procedure shall be
implemented in lieu of litigation, 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:

      (a)   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 hereunder or be deemed a
            waiver by a party hereto of any remedies to which such party would
            otherwise be entitled hereunder.

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

      (c)   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.

      (d)   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

                                       16
<PAGE>

            parties agree to submit the matter to binding arbitration or a
            private adjudicator.

      (e)   Mediation or arbitration shall take place in Pittsburgh,
            Pennsylvania unless otherwise agreed by the parties. Equitable
            remedies shall be available in any arbitration. Punitive damages
            shall not be awarded. This Section is subject to the Federal
            Arbitration Act, 9 U.S.C.A. Section 1 et seq.

      (f)   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.

      11.   Notices. All notices, requests, consents, and other communications

portion of the Shares or Registrable Securities unless and until:

          (i)  There is then in effect a registration statement under the
Securities Act covering such proposed disposition and such disposition is
made in accordance with such registration statement; or

          (ii)(A)   The transferee has agreed in writing to be bound by this
Section 2.1, (B) such Holder shall have notified the Company of the proposed
disposition and shall have furnished the Company with a detailed statement of
the circumstances surrounding the proposed disposition, and (C) if such
disposition is being effected other than pursuant to Rule 144 and if
reasonably requested by the Company, such Holder shall have furnished the
Company with an opinion of counsel, reasonably satisfactory to the Company,
that such disposition will not require registration of such shares under the
Securities Act.

     Notwithstanding the provisions of paragraphs (i) and (ii) above, no such
registration statement or opinion of counsel shall be necessary for a
transfer which does not require registration under the Securities Act by a
Holder which is (A) a partnership to its partners or former partners in

shareholders in accordance with their interests in the corporation, (C) a

     (b)  In addition to any legend required under applicable state
securities laws or as provided elsewhere in this Agreement, each certificate

imprinted with a legend substantially similar to the following:

                                       4

<PAGE>

     THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
     SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED, SOLD OR
     OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL
     REGISTERED UNDER THE ACT, UNLESS THE COMPANY HAS RECEIVED AN OPINION OF
     COUNSEL SATISFACTORY TO THE COMPANY AND ITS COUNSEL THAT SUCH
     REGISTRATION IS NOT REQUIRED OR SUCH SALE IS EFFECTED PURSUANT TO RULE
     144.

          (c)  The Company shall be obligated to reissue promptly
     unlegended certificates at the request of any holder thereof if the
     holder shall have obtained an opinion of counsel (which counsel may be

     effect that the securities proposed to be disposed of may lawfully be so
     disposed of without registration, qualification or legend; provided
     however, any legend required to remain by any other agreement shall not
     be removed.

          (d)  Any legend endorsed on an instrument pursuant to applicable

     from the appropriate blue sky authority authorizing such removal.

     2.2  Demand Registration.

     (a)  Subject to the conditions of this Section 2.2, if the Company
receives a written request from the holders of at least 50% of the shares of
Common Stock originally issued to Ford (the "Initiating Ford Holders") that
the Company file a registration statement, on Form S-1, under the Securities
Act covering the registration of such number shares of Registrable Securities
anticipated to have an aggregate offering price of not less than $5,000,000,
then within thirty (30) days of the receipt thereof, the Company shall give
written notice of such request all holders of the shares of Common Stock
originally issued to Ford (the "Ford Holders"), and subject to the
limitations of this Section 2.2, the Company shall use its best efforts to
effect, the registration under the Securities Act of all Registrable
Securities that the Ford Holders request to be registered as soon as
practicable.

     (b)  If the Initiating Ford Holders intend to distribute the Registrable
Securities covered by their request by means of an underwriting, they shall
so advise the Company as part of their request made pursuant to this Section
2.2 and with respect to requests made by the Initiating Ford Holders the
Company shall include such information in the written notice referred to in
Section 2.2(a).  In such event, the right of any Ford Holder to include its
Registrable Securities in such registration shall be conditioned upon such
Ford Holder's participation in such underwriting and the inclusion of such
Ford Holder's Registrable Securities in the underwriting (unless otherwise
mutually agreed by a majority in interest of the Initiating Ford Holders and
such Ford Holder) to the extent provided herein.  All Ford Holders proposing
to distribute their securities through such underwriting shall enter into an
underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting by a majority of the Initiating Ford Holders
(which underwriter or underwriters shall be reasonably acceptable to the
Company). Notwithstanding any other provision of this Section 2.2, if the
underwriter advises

                                      5

<PAGE>

the Company that marketing forces require a limitation of the number of
securities to be underwritten, then the Company shall advise all Ford Holders
of Registrable Securities which would otherwise be underwritten pursuant
hereto that the number of shares that may be included in the underwriting
shall be allocated to the Ford Holders of such Registrable Securities on a
pro rata basis based on the number of Registrable Securities requested by
each such Ford Holder, and the Ford Holders to be included in the
registration (including the Initiating Ford Holders).  Any Registrable
Securities excluded or withdrawn from such underwriting shall be withdrawn
from the registration.

     (c)  Subject to the conditions of this Section 2.2, if the Company
receives a written request from the Prior Holders of 40% of the Shares (or
any Common Stock issued upon conversion thereof) (the "Initiating Holders")
that the Company file a registration statement, on Form S-1, under the
Securities Act covering the registration of at least 25% of the aggregate
Registrable Securities held by the Prior Holders or such number of shares of
Registrable Securities anticipated to have an aggregate offering price of not
less than $10,000,000, then within thirty (30) days of the receipt thereof,
the Company shall give written notice of such request to all Prior Holders,
and subject to the limitations of this Section 2.2, the Company shall use its
best efforts to effect the registration under the Securities Act of all
Registrable Securities that the Prior Holders request to be registered as
soon as practicable.

     (d)  If the Initiating Holders intend to distribute the Registrable
Securities covered by their request by means of an underwriting, they shall
so advise the Company as part of their request made pursuant to this Section
2.2 and with respect to requests made by the Initiating Holders the Company
shall include such information in the written notice referred to in Sections
2.2(c). In such event, the right of any Prior Holder to include its
Registrable Securities in such registration shall be conditioned upon such
Prior Holder's participation in such underwriting and the inclusion of such
Prior Holder's Registrable Securities in the underwriting (unless otherwise
mutually agreed by a majority in interest of the Initiating Holders and such
Prior Holder) to the extent provided herein.  All Prior Holders proposing to
distribute their securities through such underwriting shall enter into an
underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting by a majority of the Initiating Holders (which
underwriter or underwriters shall be reasonably acceptable to the Company).
Notwithstanding any other provision of this Section 2.2, if the underwriter
advises the Company that marketing forces require a limitation of the number
of securities to be underwritten, then the Company shall advise all Prior
Holders of Registrable Securities which would otherwise be underwritten
pursuant hereto that the number of shares that may be included in the
underwriting shall be allocated to the Prior Holders of such Registrable
Securities on a pro rata basis based on the number of Registrable Securities
requested by each such Prior Holder, and the Prior Holders to be included in
the registration (including the Initiating Holders).  Any Registrable
Securities excluded or withdrawn from such underwriting shall be withdrawn
from the registration.

     (e)  The Company shall not be required to effect a registration pursuant
to Section 2.2:

          (i)  with respect to Section 2.2(a) after the Company has effected
two (2) registrations pursuant to Section 2.2(a) and other than in accordance
with the exceptions set

                                        6

<PAGE>

forth in Section 2.6 such registrations have been declared or ordered
effective or withdrawn by the Ford Holders, and with respect to Section
2.2(c) after the Company has effected two (2) registrations pursuant to
Section 2.2(c), and such registrations have been declared or ordered
effective or withdrawn by the Prior Holders;

          (ii) during the period starting with the date of filing of, and
ending on the date ninety (90) days following the effective date of, any
registration statement on Form S-1;

          (iii)     if within thirty (30) days of receipt of a written
request from the Initiating Ford Holders  pursuant to Section 2.2(a) or the
Initiating Holders pursuant to Section 2.2(c), as the case may be, the
Company gives notice to the Ford Holders or the Prior Holders of the
Company's intention to make its Initial Offering within ninety (90) days;

          (iv) if (A) at the time the Company receives a request for
registration in accordance with Sections 2.2(a) or (c) the Company shall then
be engaged in any material transaction (such as, by way of example only,
negotiating a merger, acquisition, joint-venture or introduction of a major
new product) the disclosure of which in a Registration Statement, in the
reasonable judgment of a majority of the Board of Directors, exercised in
good faith, would be adverse to the Company's best interests, or (B) if the
Company shall furnish to the Ford Holders requesting a registration pursuant
to Section 2.2(a) or the Prior Holders requesting a registration pursuant to
Section 2.2(c), as the case may be, a certificate signed by a majority of the
Board of Directors stating that in the Board of Director's reasonable
judgment, exercised in good faith, the Company's earnings or the occurrence
of some other material event are not at such time appropriate for disclosure,
or, that it would be seriously detrimental to the Company and its
stockholders for such registration statement to be effected at such time,
then, in either of such events, the Company shall have the right to defer
such filing for a period of not more than ninety (90) days after receipt of
the request of the Initiating Ford Holders or the Initiating Holders;
provided that such rights to delay a request shall be exercised by the
Company in the aggregate not more than once in any twelve (12) month period;
or

          (v)  prior to the earlier to occur of (a) one year from the date
hereof or (b) six months after the Closing of the Initial Offering.

     2.3  Piggyback Registration.

     (a)  The Company shall notify all Holders in writing at least ninety
(90) days prior to the filing of any registration statement under the
Securities Act for purposes of a public offering of securities of the Company
(including, but not limited to, registration statements relating to secondary
offerings of securities of the Company, but excluding registration statements
relating to employee benefit plans or with respect to corporate
reorganizations or other transactions under Rule 145 of the Securities Act)
and will afford an opportunity to include in such registration statement all
or part of such Registrable Securities held by such Holder.  Each Holder
desiring to include in any such registration statement all or any part of the
Registrable Securities held by it shall, within fifteen (15) days after the
above-described notice from the Company, so notify the Company in writing.
Such notice shall state the intended method of disposition of the Registrable
Securities by such Holder.  If a Holder decides not to include all of its
Registrable Securities in any registration statement thereafter filed by the

                                      7

<PAGE>

Company, such Holder shall nevertheless continue to have the right to include
any Registrable Securities in any subsequent registration statement or
registration statements as may be filed by the Company with respect to
offerings of its securities, all upon the terms and conditions set forth
herein.

     (b)  If the registration statement under which the Company gives notice
under this Section 2.3 is for an underwritten offering, the Company shall so
advise the Holders of Registrable Securities.  In such event, the right of
any such Holder to be included in a registration pursuant to this Section 2.3
shall be conditioned upon such Holder's participation in such underwriting
and the inclusion of such Holder's Registrable Securities in the underwriting
to the extent provided herein.  All Holders proposing to distribute their
Registrable Securities (and, if applicable, any and all other selling
shareholders who may be permitted to register shares) through such
underwriting shall enter into an underwriting agreement in customary form
with the underwriter or underwriters selected for such underwriting by the
Company.  Notwithstanding any other provision of the Agreement to the
contrary, if the underwriter determines in good faith that marketing factors
require a limitation of the number of shares to be underwritten, the number
of shares that may be included in the underwriting shall be allocated: (A) if
such registration is initiated by the Company with respect to the issuance
and sale of new shares by the Company then, first, to the Company; second, to
the Holders on a PRO RATA basis based on the total number of Registrable
Securities requested by each Holder to be registered; third, to any
stockholder of the Company (other than a Holder) on a PRO RATA basis and (B)
if such registration is initiated by any person other than the Company, then
first to the person initiating such registration; second, to the Company;
third, to the Holders on a PRO RATA basis based on the total number of
Registrable Securities requested by each Holder to be registered.  No such
reduction shall reduce the securities being offered by the initiating persons
to be included in the registration and underwriting; PROVIDED, HOWEVER, that
in no event shall the amount of securities of the selling Holders included in
the registration be reduced below thirty percent (30%) of the total amount of
securities included in such registration, unless such offering is the Initial
Offering and such registration does not include shares of any other selling
stockholders, in which event any or all of the Registrable Securities of the
Holders may be excluded in accordance with the immediately preceding
sentence. In no event shall shares of any other selling stockholder be
included in such registration which would reduce the number of shares which
may be included by Holders without the written consent of Holders of not less
than two-thirds of the Registrable Securities proposed to be sold in the
offering.

     (c)  Right to Terminate Registration.  The Company shall have the right
to terminate or withdraw any registration initiated by it under this Section
2.3 prior to the effectiveness of such registration whether or not any Holder
has elected to include securities in such registration.  The Registration
Expenses of such withdrawn registration shall be borne by the Company in
accordance with Section 2.6 hereof.

     2.4  Form S-3 Registration

     In case the Company shall receive from (i) any Holder or Holders of (A)
a majority of the Registrable Securities relating to the Company's Series A
Convertible Preferred Stock (the "Series A Registrable Securities"), (B) a
majority of the Registrable Securities relating to the Company's Series C
Convertible Preferred Stock (the "Series C Registrable Securities"),

relating to the Company's Common Stock originally issued to Ford (the "Ford
Registrable Securities") (such Holders under (i) and (ii) being referred to
as the "Initiating S-3 Holders") a written request or requests that the
Company effect a registration on Form S-3 (or any successor to Form S-3) or
any similar short-form registration statement and any related qualification
or compliance with respect to all or a part of the Registrable Securities
owned by such Holder or Holders, the Company will:

     (a)  promptly give written notice of the proposed registration, and any
related qualification or compliance, to all other Holders of Registrable
Securities; and

     (b)  as soon as practicable, effect such registration and all such
qualifications and compliances as may be so requested and as would permit or
facilitate the sale and distribution of all or such portion of such Holder's
or Holders' Registrable Securities as are specified in such request, together
with all or such portion of the Registrable Securities of any other Holder or
Holders joining in such request as are specified in a written request given
with fifteen (15) days after receipt of such written notice from the Company;
provided, however, that the Company shall not be obligated to effect any such
registration, qualification or compliance pursuant to this Section 2.4:

          (i)  if Form S-3 (or any successor or similar form) is not
available for such offering by the Holder;

          (ii) if the Holders, together with the holders of any other
securities of the Company entitled to inclusion in such registration, propose
to sell Registrable Securities and such other securities (if any) at an
aggregate price to the public of less than $500,000;

          (iii)     if (A) at the time the Company receives a request for
registration in accordance with this Section 2.4 the Company shall then be
engaged in any material transaction (such as, by way of example only,
negotiating a merger, acquisition, joint-venture or introduction of a major
new product) the disclosure of which in a Registration Statement, in the
reasonable judgment of a majority of the Board of Directors, exercised in
good faith, would be adverse to the Company's best interests, or (B) if the
Company shall furnish to the Holders requesting a registration pursuant to
this Section 2.4 a certificate signed by a majority of the Board of Directors
of the Company stating in the Board of Directors' reasonable judgment,
exercised in good faith, the Company's earnings or the occurrence of some
other material event are not at such time appropriate for disclosure, or that
it would be seriously detrimental to the Company and its stockholders for
such Form S-3 Registration to be effected at such time, then, in either of
such events, the Company shall have the right to defer the filing of the Form
S-3 registration statement for a period of not more than ninety (90) days
after receipt of the request of the Holder or Holders under this Section 2.4;
provided that such rights to delay a request shall be exercised by the
Company in the aggregate not more than once in any twelve (12) month period;
or

          (iv) in any particular jurisdiction in which the Company would be
required to qualify to do business or to execute a general consent to service
of process in effecting such registration, qualification or compliance.

     (c)  Subject to the foregoing, the Company will file a Form S-3
registration statement covering the Registrable Securities and other
securities so requested to be registered as soon as practicable after receipt
of the request or requests of the Holders.

     2.5  IPO Allocation.

     In the event of a bona fide, underwritten initial public offering of the
capital stock of the Company (the "IPO"), the Company shall use commercially
reasonable efforts to require that the managing underwriters of the IPO
establish a directed share program (the "PROGRAM") in connection with the
IPO. The Program shall consist of that number of shares of capital stock (the
"PROGRAM SHARES") determined by dividing $3,000,000 by the initial price to
the public set forth on the cover page of the final prospectus distributed in
connection with the IPO (the "IPO PRICE"), provided that, if necessary to
complete the IPO, the number of Program Shares may be reduced to the maximum
number permitted under the rules and requirements of the NASD.  The Company
shall cause the managing underwriters (subject to the consent of the
underwriters) to give priority to the holders of the Company's Series C
Convertible Preferred Stock (or Common Stock issuable upon conversion
thereof) (the "SERIES C HOLDERS"), PRO RATA in accordance with their relative
holdings of Series C Convertible Preferred Stock (or Common Stock issued upon
conversion thereof) with respect to the Program Shares in allocating the
shares available for purchase in the Program.  The Series C Holders, PRO RATA
as aforesaid, shall have the option, but not the obligation, to purchase all
or any portion of the Program Shares at the IPO Price.  Notwithstanding the
foregoing, in no event shall the Investors designated on the signature pages
hereto as the "TCV Investors" have the rights under this Section 2.5 with
respect to less than such number of Program Shares that, when multiplied by
the IPO Price, equals $1,500,000, (such product being referred to as the
"Program Value"), and if the Program Value shall be less than $1,500,000 then
the TCV Investors shall have the rights under this Section 2.5 with respect
to all of the Program Shares (the number of Program Shares as to which the
TCV Investors are to have the rights under this Section 2.5 in accordance
with this sentence are referred to as the "TCV Minimum Shares").  If, in
order to give effect to the operation of the preceding sentence, the
Investors other than the TCV Investors obtain rights under this Section 2.5
with respect to less than their respective PRO RATA share of the Program
Shares, then (i) such other Investors shall have the rights under this
Section 2.5 with respect to all of the Program Shares other than the TCV
Minimum Shares, if there shall be any Program Shares in addition to the TCV
Minimum Shares, and (ii) such other Investors shall share such rights PRO
RATA in accordance with their relative holdings of Series C Convertible
Preferred Stock (or Common Stock issued upon the conversion thereof.

     2.6  Expenses of Registration.

     Except as specifically provided herein, all Registration Expenses
incurred in connection with any registration, qualification or compliance
pursuant to Section 2.2 or any registration under Section 2.3 or Section 2.4
herein shall be borne by the Company.  All Selling Expenses incurred in
connection with any registrations hereunder shall be borne by the holders

                                     10
<PAGE>

of the securities so registered pro rata on the basis of the number of shares
so registered.  The Company shall not, however, be required to pay for
expenses of any registration proceeding begun pursuant to Section 2.2 or 2.4,
the request of which has been subsequently withdrawn by the Initiating Ford
Holders, with respect only to a request made pursuant to Section 2.2(a), the
Initiating Holders or the Initiating S-3 Holders, as the case may be, unless
(a) the withdrawal is based upon material adverse information concerning the
Company of which the Initiating Ford Holders, the Initiating Holders or the
Initiating S-3 Holders, as the case may be were not aware at the time of such
request, (b) the Ford Holders agree to forfeit its right to one requested
registration pursuant to Section 2.2(a) or (c) the Prior Holders of a
majority of Registrable Securities agree to forfeit their right to one
requested registration pursuant to Section 2.2(c), in which event such right
shall be forfeited by all Prior Holders.  If the Holders are required to pay
the Registration Expenses, such expenses shall be borne by the holders of
securities (including Registrable Securities) requesting such registration in
proportion to the number of shares for which registration was requested.  If
the Company is required to pay the Registration Expenses of withdrawn
offering pursuant to clause (a) above, then the Holders shall not forfeit
their rights pursuant to Section 2.2 or Section 2.4 to a demand registration.

     2.7  Obligations of the Company.

     Whenever required to effect the registration of any Registrable
Securities, the Company shall, as expeditiously as reasonably possible:

     (a)  Prepare and file with the SEC a registration statement with respect
to such Registrable Securities and use all reasonable efforts to cause such
registration statement to become effective, and upon the request of Ford with
respect to registrations pursuant to Section 2.2(a), the Initiating Holders
or the Initiating S-3 Holders, as the case may be, keep such registration
statement effective for up to one hundred and eighty (180) days or, if
earlier, until the Holder or Holders have completed the distribution related
thereto.

     (b)  Prepare and file with the SEC such amendments and supplements to
such registration statement and prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of
the Securities Act with respect to the disposition of all securities covered
by such registration statement.

     (c)  Furnish to the Holders such number of copies of the prospectus,
including a preliminary prospectus, in conformity with the requirements of
the Securities Act, and such other documents as they may reasonably request
in order to facilitate the disposition of the Registrable Securities owned by
them.

     (d)  Use all reasonable efforts to register and qualify the securities
covered by such registration under such other securities laws and Blue Sky
laws of such jurisdictions as shall be reasonably requested by the Holders,
provided that the Company shall not be required in connection therewith or as
a condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions.

     (e)  In the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and
customary form, with the managing

                                      11

<PAGE>

underwriter(s) of such offering.  Each Holder participating in such
underwriting shall also enter into and perform its obligations under such an
agreement.

     (f)  Notify each Holder of Registrable Securities covered by such
registration statement that a prospectus relating thereto is required to be
delivered under the Securities Act of any event that would cause the
prospectus included in such registration statement, as then in effect, to
include an untrue statement of a material fact or to omit to state a material
fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances then existing.

     (g)  Furnish, at the request of Ford with respect to offerings made
pursuant to Section 2.2(a), the Initiating Holders holding a majority of the
shares participating in the offering or the Initiating S-3 Holders holding a
majority of the shares participating in the offering, as the case may be, on
the date that such Registrable Securities are delivered to the underwriters
for sale, if such securities are being sold through underwriters, or, if such
securities are not being sold through underwriters, on the date that the
registration statement with respect to such securities becomes effective, (i)
an opinion, dated as of such date, from the counsel representing the Company
for the purposes of such registration, in the form and substance as is
customarily given to underwriters in an underwritten public offering and
reasonably satisfactory to a majority of the Holders requesting registration,
addressed to the underwriters, if any, and to the Holders requesting the
registration of their Registrable Securities and (ii) a letter dated as of
such date, from the independent certified public accountants of the Company,
in form and substance as is customarily given by independent certified public
accountants to underwriters  in an underwritten public offering and
reasonably satisfactory to a majority of the Holders requesting registration,
addressed to the underwriters, if any, and if permitted by applicable
accounting standards, to the Holders requesting the registration of their
Registrable Securities.

     2.8  Termination of Registration Rights.

     All registration rights granted to a Holder under this Article II (other
than under Section 2.3 with respect to underwritten offerings) shall
terminate and be of no further force and effect upon the earlier of (i) the
fifth anniversary of the consummation of the Initial Offering and (ii) such
date as all Registrable Securities held by and issuable to such Holder may be
sold in the manner described in Rule 144 during any ninety (90) day period.

     2.9  Delay of Registration; Furnishing Information.

     (a)  No holder shall have any right to obtain or seek an injunction
restraining or otherwise delaying any such registration as the result of any
controversy that might arise with respect to the interpretation or
implementation of this Section 2.

     (b)  It shall be a condition precedent to the obligations of the Company
to take any action pursuant to Sections 2.2, 2.3 or 2.4 that the selling
Holders shall furnish to the Company such information regarding themselves,
the Registrable Securities held by them and the intended method of
disposition of such securities as shall be required to effect the
registration of their Registrable Securities.

     2.10 Indemnification.

     In the event any Registrable Securities are included in a registration
statement under Sections 2.2, 2.3 or 2.4:

     (a)  To the extent permitted by law, the Company shall indemnify and
hold harmless each Holder, the partners, officers, directors and legal
counsel of each Holder, any underwriter (as defined in the Securities Act)
for such Holder and each person, if any, who controls such Holder or
underwriter within the meaning of the Securities Act or the Exchange Act,
against any losses, claims, damages or liabilities (joint or several) to
which they may become subject under the Securities Act, the Exchange Act or
other federal or state law, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon
any of the following statements, omissions or violations (collectively a
"Violation") by the Company: (i) any untrue statement or alleged untrue
statement of a material fact contained in such registration statement,
including any preliminary prospects or final prospectus contained therein and
any amendments or supplements thereto, (ii) the omission or alleged omission
to state a material fact required to be stated therein, or necessary to make
the statements therein not misleading, or (iii) any violation or alleged
violation by the Company of the Securities Act, the Exchange Act, any state
securities laws or any rule or regulation promulgated under the Securities
Act, the Exchange Act, any state securities laws in connection with the
offering covered by such registration statement; and the Company shall
reimburse each such Holder, partner, officer or director, underwriter or
controlling person on a current basis for any legal or other expense
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action; provided however, that the
indemnity agreement contained in this Section 2.10(a) shall not apply to
amounts paid in settlement of any such loss, claims, damage, liability or
action if such settlement is effected without the consent of the Company,
which consent shall not be unreasonably withheld, nor shall the Company be
liable in any such case for any such loss, claim, damage, liability or action
to the extent that it arises out of or is based upon a Violation which occurs
in reliance upon and in conformity with written information furnished
expressly for use in connection with such registration by such Holder,
partner, officer, director, underwriter or controlling person of such Holder.

     (b)  To the extent permitted by law, each Holder shall, if Registrable
Securities held by such Holder are included in the securities as to which
such registration qualifications or compliance is being effected, indemnify
and hold harmless the Company, each of its directors, its officers, and legal
counsel and each person, if any, who controls the Company within the meaning
of the Securities Act, any underwriter and any other Holder selling
securities under such registration statement or any of such other Holder's
partners, directors or officer or any person who controls such Holder,
against any losses, claims, damages or liabilities (joint or several) to
which the Company or any such director, officer, controlling person,
underwriter or other such Holder, or partner, director, officer or
controlling person of such other Holder may become subject under the
Securities Act, the Exchange Act or other federal or state law, insofar as
such losses, claims, damages or liabilities (or actions in respect thereto)
arise out of or are based upon any Violation, in each case to the extent (and
only to the extent) that such Violation occurs due to the Company's reliance
upon written information furnished by such Holder under an instrument duly
executed by such Holder and stated to be specifically for use in connection
with such registration; and each such Holder shall reimburse any legal or
other expenses

                                       13

<PAGE>

reasonably incurred by the Company or any such director, officer, controlling
person, underwriter or other Holder, or partner, officer, director or
controlling person of such other Holder in connection with investigating or
defending any such loss, claim, damage, liability or action if it is
judicially determined that there was such a Violation; provided, however,
that the indemnity agreement contained in this Section 2.10(b) shall not
apply to amounts paid in settlement of any such loss, claim, damage,
liability or action if such settlement is effected without the consent of the
Holder, which consent shall not be unreasonably withheld; provided further,
that in no event shall any indemnity under this Section 2.10 exceed the net
proceeds from the offering received by such Holder.

     (c)  Promptly after receipt by an indemnified party under this Section
2.10 of notice of the commencement of any action (including any governmental
action), such indemnified party shall, if a claim in respect thereof is to be
made against any indemnifying party under this Section 2.10, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any indemnifying party
similarly notified, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party
shall have the right to retain its own counsel and own separate local
counsel, with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential
differing interests between such indemnified party and any other party
represented by such counsel in such proceeding.  The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if materially prejudicial to its ability to
defend such action, shall relieve such indemnifying party of any liability to
the indemnified party under this Section 2.10 to the extent prejudiced, but
the omission so to deliver written notice to the indemnifying party will not
relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 2.10.

     (d)  If the indemnification provided for in this Section 2.10 is held by
a court of competent jurisdiction to be unavailable to an indemnified party
with respect to any losses, claims, damages or liabilities referred to
herein, the Indemnifying party, in lieu of indemnifying such indemnified
party thereunder, shall to the extent permitted by applicable law contribute
to the amount paid or payable by such indemnified party as a result of such
loss, claim, damage or liability in such proportion as is appropriate to
reflect the relative fault of the indemnifying party on the one hand and of
the indemnified party on the other in connection with the Violation(s) that
resulted in such loss, claim, damage or liability, as well as any other
relevant equitable considerations.  The relative fault of the indemnifying
party and of the indemnified party shall be determined by a court of law by
reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission to state a material fact relates
to information supplied by the indemnifying party or by the indemnified party
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission; provided, that
in no event shall any contribution by a Holder hereunder exceed the net
proceeds from the offering received by such Holder.

     (e)  The obligations of the Company and Holders under this Section 2.10
shall survive completion of any offering of Registrable Securities in a
registration statement and the

                                       14

<PAGE>

termination of this Agreement.  No indemnifying party, in the defense of any
such claim or litigation, shall, except with the consent of each indemnified
party, consent to entry of any judgment or enter into any settlement which
does not include as an unconditional term thereof the giving by the claimant
or plaintiff to such indemnified party a release from all liability in
respect to such claim or litigation.

     2.11 Assignment of Registration Rights.

     The rights to cause the Company to register Registrable Securities
pursuant to this Article II may be assigned by a Holder to a transferee or
assignee of Shares or Registrable Securities, provided such transferee or
assignee (i) is a subsidiary, parent, general partner, limited partner or
retired partner of a Holder, (ii) is a Holder's family member or trust for
the benefit of an individual Holder, or (iii) acquires at least one hundred
thousand (100,000 Shares or Registrable Securities (as adjusted for stock
splits and combinations) and is not a competitor of the Company (as
reasonably determined by the Board of Directors); provided, however, (A) the
transferor shall, within ten (10) days after such transfer, furnish to the
Company written notice of the name and address of such transferee or assignee
and the securities with respect to which such registration rights are being
assigned and (B) such transferee shall agree to be subject to all
restrictions set forth in this Agreement and the Restated Co-Sale Agreement.

     2.12 Amendment of Registration Rights.

     Any provision of this Section 2 may be amended and the observance
thereof may be waived (either generally or in a particular instance and
either retroactively or prospectively), only with the written consent of the
holders of a majority of the Series A Registrable Securities, voting or
acting separately as a class, a majority of the Series C Registrable
Securities, voting or acting separately as a class, and a majority of the
Series D Registrable Securities, voting or acting separately as a class, and
a majority of the Series E Registrable Securities, voting or acting
separately as a class, and the Ford Holders holding in interest a majority of
the Ford Registrable Securities, voting as a separate class, provided that
all Holders are affected by such amendment or waiver in a substantially
similar fashion.  If any amendment treats any class of holders differently
than any other class, the affected class must approve or waive the amendment
or modification by a majority vote of the affected class.  Any amendment or
waiver effected in accordance with this Section 2.12 shall be binding upon
each Holder and the Company.  By acceptance of any benefits under this
Section 2, Holders hereby agree to be bound by the provisions hereunder.

     2.13 Limitation on Subsequent Registration Rights

     After the date of this Agreement, the Company shall not, without the
prior written consent of the holders of a majority of the Series A
Registrable Securities, voting or acting separately as a class, a majority of
the Series C Registrable Securities, voting or acting separately as a class,
a majority of the Series D Registrable Securities, voting or acting
separately as a class, and a majority of the Series E Registrable Securities,
voting or acting separately as a class, and the Ford Holders holding in
interest a majority of the Ford Registrable Securities, voting as a separate
class, enter into any agreement with any holder or prospective holder of any
securities

                                       15

<PAGE>

of the Company that would grant such holder any registration rights with
respect to such securities.

     2.14 "Market Stand-Off" Agreement.

     If requested by the Company or the representative of the underwriters of
the Common Stock (or other securities), each Holder and a transferee of a
Holder, regardless of whether such transferee has registration rights
hereunder, shall not sell or otherwise transfer or dispose of any Registrable
Securities held by such Holder (other than those included in the
registration) for a period specified by the representative of the
underwriters not to exceed one hundred eighty (180) days following the
effective date of a registration statement of the Company filed under the
Securities Act, provided that:

     (a)  such agreement shall apply only to the Initial Offering;

     (b)  all officers and directors of the Company and holders of at least
one percent (1%) of the Company's voting securities enter into similar
agreement; and

     (c)  such agreement shall provide that any discretionary waiver or
termination of the restrictions of such agreements by the Company or the
representatives of the underwriters shall apply to all persons subject to
such agreements pro rata based on the number of Registrable Securities held.

     The obligations described in this Section 2.14 shall not apply to a
registration relating solely to employee benefit plans on Form S-1 or Form
S-8 or similar forms that may be promulgated in the future, or a registration
relating solely to a Commission Rule 145 transaction on Form S-4 or similar
forms that may be promulgated in the future.  The Company may impose
stop-transfer instructions with respect to the shares of Common Stock (or
other securities) subject to the foregoing restriction until the end of said
one hundred eighty (180) day period.

     2.15 Rule 144 Reporting.

     With a view to making available to the Holders the benefits of certain
rules and regulations of the SEC which may permit the sale of the Registrable
Securities to the public without registration, the Company agrees to use its
best efforts to:

     (a)  Make and keep public information available, as those terms are
understood and defined in SEC Rule 144 or any similar or analogous rule
promulgated under the Securities Act, at all times that the Company is
subject to the reporting requirements of the Exchange Act, as amended;

     (b)  File with the SEC, in a timely manner, all reports and other
documents required of the Company under the Exchange Act; and

     (c)  So long as a Holder owns any Shares or Registrable Securities,
furnish to such Holder forthwith upon request a written statement by the
Company as to its compliance with the reporting requirements of said Rule 144
of the Securities Act, and of the Exchange Act (at any time after it has
become subject to such reporting requirements), a copy of the most

                                      16

<PAGE>

recent annual or quarterly report of the Company, and such other reports and
documents as a Holder may reasonably request in availing itself of any rule
or regulation of the SEC allowing it to sell any such securities without
registration.

SECTION 3 COVENANTS OF THE COMPANY.

     3.1  Basic Financial Information and Reporting.

     (a)  The Company will maintain true books and records of account in

with generally accepted accounting principles consistently applied, and will
set aside on its books all such proper accruals and reserves as shall be
required under generally accepted accounting principles consistently applied.
 In addition to the information described in Section 3.1(b), (c) and (d), the
Company shall provide in a timely manner any other information concerning the
Company and its business and affairs as any of the Investors may from time to
time reasonably request.

     (b)  As soon as practicable after the end of each fiscal year of the
Company and so long as any of the Shares are outstanding, and in any event
within one hundred twenty (12) days thereafter, the Company will furnish to
each Investor a consolidated balance sheet of the Company, as at the end of
such fiscal year, and an audited consolidated income statement and an audited
consolidated cash flow statement of the Company, for such year, all prepared
in accordance with generally accepted accounting principles consistently
applied and setting forth in each case in comparative form the figures from
the previous fiscal year, with an explanation of any material differences
between them, all in reasonable detail.  Such financial statements shall be
accompanied by a report and opinion thereon by independent public accountants
of national standing selected by the Company's Board of Directors and a
report by management with a discussion of the Company's business, including
any changes in the Company's financial condition and any significant business
developments.

     (c)  As long as any of the Shares are outstanding, the Company will
furnish each Investor, as soon as practicable after the end of the first,
second and third quarterly accounting periods in each fiscal year of the
Company, and in any event within forty-five (45) days thereafter, a
consolidated balance sheet of the Company as of the end of each such
quarterly period, and a consolidated income statement and a consolidated cash
flow statement of the Company for such period and for the current fiscal year

year, with an explanation of any material differences between them.  Such
financial statements shall be accompanied by a report by management with a
discussion of the Company's business, including any changes in the Company's
financial condition and any significant business developments.

     (d)  As long as any of the Shares are outstanding, the Company will
furnish each Investor (i) at least thirty (30) days prior to the beginning of
each fiscal year an annual budget and operating plans for such fiscal year
(and, as soon as available, any subsequent revisions thereto); and (ii) as
soon as practicable after the end of each month, and in any event

     Each Investor or its authorized representatives shall have the right to
visit and inspect any of the properties of the Company or any of its
subsidiaries, including its corporate and financial records, and to discuss
the affairs, finances and accounts of the Company or any of its subsidiaries
with its officers, and to review such information as it may reasonably
request all at such reasonable times and as often as may be reasonably
requested; provided, however, that the Company shall not be obligated under
this Section 3.2 with respect to a competitor of the Company or with respect
to information which the Board of Directors determines in good faith is
confidential and should not, therefore, be disclosed.

     3.3  Confidentiality of Records.

     Each Investor agrees to use, and to use its diligent efforts to ensure
that its authorized representatives use, the same degree of care as such
Investor uses to protect its own confidential information to keep
confidential any information furnished to it which the Company identifies as
being confidential or proprietary (so long as such information is not in the
public domain), except that such Investor may disclose such proprietary or
confidential information to any partner, subsidiary or parent of such
Investor for the purpose of evaluating its investment in the Company as long
as such partner, subsidiary or parent agrees to be bound by the
confidentiality provisions of this Section 3.3.  Notwithstanding the
foregoing, each Investor shall be free to distribute to its partners or
shareholders summary information describing the Company's performance.

     3.4  Reservation of Common Stock.

     The Company will at all times reserve and keep available, solely for
issuance and delivery upon the conversion of Shares, all Common Stock
issuable from time to time upon conversion of all the Shares.

and other stock equivalents issued after the date of this Agreement to
employees, directors, consultants and other service providers shall be
subject to vesting over a minimum of four year period and with respect to any

shall provide that upon such person's termination of employment or service
with the Company, with or without cause, the Company or its assignee (to the
extent permissible under applicable securities laws and other laws) shall
have the option to purchase at cost any unvested shares of stock held by such
person.

                                      18

<PAGE>

     3.6  Termination of Covenants.

     The provisions of 3.1, 3.2, 3.3 and 3.4 of this Agreement shall expire,
terminate and be of no further force of effect on the date the Initial
Offering is consummated.

SECTION 4 RIGHTS OF FIRST REFUSAL.

     4.1  Subsequent Offerings.

     The Prior Holders and the Ford Holders shall have a right of first
refusal to purchase their PRO RATA portion of the Equity Securities, as
defined below, that the Company may, from time to time, propose to sell and
issue after the date of this Agreement, other than the Equity Securities
excluded by Section 4.6 hereof.  The term "Equity Securities" shall mean (i)
any Common Stock, Preferred Stock or other security of the Company (other
than debt securities which are not convertible into and do not carry rights
to acquire any capital stock of the Company), (ii) any security convertible,
with or without consideration, into any Common Stock, Preferred Stock or
other security (including any option to purchase such a convertible
security), (iii) any security carrying any warrant or right to subscribe to
or purchase any Common Stock, Preferred Stock or other security or (iv) any
such warrant or right. Notwithstanding anything to the contrary contained
elsewhere in this subsection 4.1, Ford's initial pro-rata portion shall be
deemed to be 27.5% of any such issuance.  At such time as Ford's actual
ownership percentage of Vastera's issued and outstanding capital stock
declines below 27.5%, Ford's pro-rata portion of any issuance of Equity
Securities shall be such actual percentage ownership of the issued and
outstanding capital stock of Vastera, and thereafter if Ford's ownership
percentage of Vastera's issued and outstanding capital stock increases above
27.5%, Ford's pro-rata portion of any issuance of Equity Securities shall be

     4.2  Exercise of Rights.

     If the Company proposes to issue any Equity Securities, it shall give
the Prior Holders and the Ford Holders written notice of its intention,
describing the Equity Securities, the price and the terms and conditions upon
which the Company proposes to issue the same.  The Prior Holders and the Ford
Holders shall have fifteen (15) days from the giving of such notice to agree
to purchase the Equity Securities for the price and upon the terms and
conditions specified in the notice by giving written notice to the Company
and stating therein the quantity of Equity Securities to be purchased.
Notwithstanding the foregoing, the Company shall not be required to offer or
sell such Equity Securities to any such Prior Holder or Ford Holder if it
would cause the Company to be in violation of applicable federal securities
laws by virtue of such offer or sale.

     4.3  Issuance of Equity Securities to Other Persons.

     If any Prior Holder or Ford Holder fails to exercise in full the rights
of first refusal, the Company shall have ninety (90) days thereafter to sell
the Equity Securities in respect of which the Prior Holder's rights or Ford
Holder's rights were not exercised, at a price and upon general terms and
conditions materially no more favorable to the purchasers thereof than
specified in the Company's notice to the Prior Holder or Ford Holder pursuant
to Section 4.2 hereof.  If the Company has not sold such Equity Securities
within 90 days of the notice

                                       19

provided pursuant to Section 4.2, the Company shall not thereafter issue or
sell such Equity Securities, without first offering such securities to the
Prior Holder or the Ford Holder in the manner provided above.

     4.4  Termination of Rights of First Refusal.

     The rights of first refusal established by this Section 4 shall
terminate upon either (a) the date of the Initial Offering or (b) with
respect to Prior Holders holding Series A Convertible Preferred Stock or
Series B Convertible Preferred Stock, if fewer than 30% of the number of such
Shares that are outstanding (or in the case of Series B Convertible Preferred
Stock, that are issuable upon the exercise of an option therefor that is
outstanding) as of the date of this Agreement remain outstanding or (c) with
respect to Prior Holders holding Series C Convertible Preferred Stock or
Series C-1 Convertible Preferred Stock, if fewer than 20% of the number of

Preferred Stock, that are issuable upon the exercise of options therefor that
are outstanding) as of the date of this Agreement remain outstanding or (d)

date of this Agreement remain outstanding or (f) with respect to Ford Holders
holding shares of Common Stock originally issued to Ford, if fewer than 30%
of the number of such shares that are outstanding as of the date of this
Agreement remain outstanding.

     4.5  Transfer of Rights of First Refusal.

     The rights of first refusal of the Prior Holders and the Ford Holders
under this Section 4 may be transferred to the same parties, subject to the
same restrictions as any transfer of registration rights pursuant to Section
2.11.

application to any of the following Equity Securities:

                               LICENSE AGREEMENT

This Agreement is made this fourteenth day of July, 2000 (the "Effective Date"),
by and between Ford Motor Company, a Delaware Corporation having its principle
place of business at One American Road, Dearborn, MI 448121, (hereinafter
"Ford") and Vastera Solution Services Corporation, a Delaware corporation having
a principle place of business at 45025 Aviation Drive, Dulles, VA 20166
(hereinafter "Vastera").

WHEREAS, Ford has developed and owns certain Information Technology that it uses
in its internal operations concerning the import and export trade management
portion of its business.

WHEREAS, Ford and Vastera are entering into another agreement, contemporaneously
herewith, in which Vastera will convey to Ford a certain equity share in
Vastera's business (the "Stock Transfer Agreement").

WHEREAS, Ford and Vastera are entering into this Agreement in order to convey
sufficient rights in certain Ford-owned Information Technology to allow Vastera
to conduct Vastera's business and to make improvements in such Information
Technology.

NOW, THEREFORE, for and in consideration of the agreements set forth below,
Vastera and Ford agree as follows:

1.     DEFINITIONS.

"Information Technology" means the computer programs and systems listed in
Schedule A (including any associated files, documentation and data, to the
extent such data is not proprietary or unique to Ford's business) and any
modifications or Derivative Works based upon any such program, system, file,
documentation or data.

"Ford's Intellectual Property" means know-how or inventions held as trade
secrets; inventions for which applications for patents are filed in any country;
patented inventions; writings, data and software and any other works of
authorship that are protectable by trade secrets and/or copyrights and embodied
in Information Technology.

"Derivative Work" means a work of authorship based on one or more preexisting
works, including, without limitation, a translation, condensation,
transformation, expansion or adaptation, which, if prepared without
authorization of the owner of the copyright of such preexisting work, would
constitute a copyright infringement. The term "Derivative Work" does not include
the preexisting work upon which the Derivative Work is based.

<PAGE>

"HSR Act" means the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended, and the related regulations and published interpretations.

2.     LICENSE.

In consideration of the equity share to be provided to Ford under the Stock
Transfer Agreement executed contemporaneously herewith, Ford hereby grants to
Vastera a worldwide, nonexclusive, permanent, personal, nontransferable license
under Ford's Intellectual Property with rights to use, reproduce, modify and
prepare Derivative Works based upon Information Technology for the sole purpose
of supporting Vastera's business of providing import and export trade management
services to Ford, subsidiaries of Ford, and Vastera's other customers.

3.     OWNERSHIP.

Ford represents either that it owns all rights, title and interest in
Information Technology and all copies thereof, or that some rights in
Information Technology are owned by one or more third party and Ford has the
right to grant the rights granted herein. Vastera agrees that it will not make
any claim of ownership to any right, title or interest to Ford's Intellectual
Property, Information Technology or copies thereof contrary to Ford's or such
third party's claim of ownership.

4.     ASSIGNMENT.

Neither this Agreement nor any rights granted hereunder, in whole or in part
shall be assignable or otherwise transferable by Vastera, except that Vastera
may assign this Agreement (including all rights granted hereunder) without the
consent of Ford to an entity that acquires all, or substantially all, of the
business of the Vastera, so long as (i) such acquiring entity is not a
competitor of Ford or Ford Subsidiaries and (ii) such acquiring entity agrees to
utilize the rights granted hereunder only in support of Ford and Ford Subsidiary
operations. Except as provided in this Section 4, nothing in this Agreement
grants to Vastera the right to assign, sell, lease, loan or otherwise transfer
Information Technology in whole or in part to a third party.

5.     MAINTENANCE.

Ford shall provide Information Technology maintenance support in connection with
this Agreement as further described in Schedule A.

6.     FORD'S IP WARRANTY/INDEMNITY.

(a)    Ford warrants that the transfer to Vastera and Vastera's licensed use of
Information Technology, in its original form as of the Effective Date, will not
infringe any copyrights or trade secrets of any other entity. Ford will
indemnify and defend Vastera from any claim, liability and expense, including
reasonable attorneys' fees, arising out of any breach of the foregoing warranty,
provided that Vastera notifies Ford in a timely fashion of such claim. In the
event a

                                       2
<PAGE>

claim of infringement is asserted or Ford has reason to believe such a claim may
be asserted, Ford may replace or arrange to modify the Information Technology to
make it non-infringing, or Ford may procure at its expense a license for Vastera
to use the rights allegedly infringed.

(b)    Ford represents that it has no knowledge of any threat or allegation that
Information Technology infringes or may infringe the intellectual property
rights of any third party.

(c)    Ford will indemnify Vastera against any claim, liability, and expense,
including reasonable attorneys' fees, arising out of and associated with a final
judgment of infringement by Vastera of any third party patents that results from
Vastera's licensed use of Information Technology, provided that such indemnity
is subject to the following conditions ("Patent Indemnity"):

      (i)    Patent Indemnity applies only to the infringement claims brought
      against Vastera for patents that were issued on or before the Effective
      Date;

      (ii)   Ford's obligations under the Patent Indemnity do not apply to
      the extent that the patent infringement by Vastera is attributable to
      Vastera's use of Derivative Works;

      (iii)  Ford's aggregate liability in connection with the Patent Indemnity
      is limited to the infringement-related damages incurred by Vastera solely
      in connection with Vastera's use of the Information Technology in
      supporting Ford's or a Ford Subsidiary's import/export customs operations,
      and does not extend to Vastera's use of the Information Technology in
      providing services to others.

      (iv) Ford's maximum aggregate liability in connection with the Patent
      Indemnity shall not exceed Ten Million Dollars ($10,000,000); and

      (v) Ford shall have no obligation under the Patent Indemnity for any
      claims brought against Vastera after the third anniversary of the
      Effective Date.

(d)    In the event a claim that Vastera's use of Information Technology
infringes a third party's patent commences in any court against Vastera during
the period of Ford's obligations under the Patent Indemnity, or Ford has reason
to believe such a claim may be asserted, Ford may replace or arrange to modify
the Information Technology to make it non-infringing, or Ford may procure at its
expense a license for Vastera to use the rights allegedly infringed.

(e)    Ford shall be entitled (but is not required) to participate in Vastera's
defense of any patent infringement-related claim against Vastera in which the
Patent Indemnity applies, and to employ counsel at Ford's expense to assist in
the handling of such claims. Vastera shall cooperate with Ford in taking any
reasonable actions that would minimize Ford's liability associated with the
Patent Indemnity (e.g., participation in settlement negotiations, etc.). Vastera
will not compromise or settle any patent infringement-related claims in which
the Patent Indemnity applies without the prior written consent of Ford.

(f)    Until the third anniversary of the Effective Date, Vastera shall promptly
notify Ford in writing of any actual or potential patent infringement claims
that arise or may be reasonably expected to arise in connection with Vastera's
use of Information Technology.

                                       3
<PAGE>

(g)    Vastera shall perform an infringement investigation, at Vastera's
expense, to determine if Vastera's use of Information Technology is likely to
infringe the patent rights of any third party and promptly disclose to Ford
the results of such investigation. The investigation and disclosure to Ford
will be completed prior to December 31, 2000. Following such disclosure,
Vastera shall cooperate with Ford in the formulation and execution of a joint
strategy to address any potential patent infringement issues related to
Vastera's use of Information Technology.

7.     WARRANTY DISCLAIMER AND LIMITATION OF LIABILITY.

       (a)    EXCEPT TO THE EXTENT OF THE REPRESENTATION AND WARRANTY MADE
              ABOVE, FORD MAKES NO OTHER REPRESENTATIONS OR WARRANTIES, EXPRESS
              OR IMPLIED. BY WAY OF EXAMPLE BUT NOT OF LIMITATION, FORD MAKES NO
              REPRESENTATIONS OR WARRANTIES OF MERCHANTABILITY OR FITNESS FOR
              ANY PARTICULAR PURPOSE. FORD 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 INFORMATION TECHNOLOGY.

       (b)    FORD MAKES NO WARRANTY OR REPRESENTATION THAT INFORMATION
              TECHNOLOGY CAN BE USED FOR ANY PARTICULAR FUNCTION OR THAT VASTERA
              HAS THE ABILITY TO USE IT. 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 INFORMATION TECHNOLOGY. VASTERA'S USE OF
              THE LICENSED SOFTWARE WILL NOT DIMINISH VASTERA'S OBLIGATIONS OR
              MITIGATE ANY FAILURES TO PERFORM SPECIFIC SERVICES UNDER ANY
              PURCHASE ORDER CONTRACTS ISSUED TO VASTERA BY FORD.

       (c)    EXCEPT TO THE EXTENT OF THE REPRESENTATION, WARRANTY AND INDEMNITY
              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,
              WHETHER OR NOT THE EXERCISE OF ANY RIGHT GRANTED HEREIN
              NECESSARILY EMPLOYS OR REQUIRES THE PRACTICE OF ANY SUCH EXISTING
              OR SUBSEQUENTLY CREATED THIRD PARTY INTELLECTUAL PROPERTY RIGHTS.

                                       4
<PAGE>

8.     VASTERA INDEMNITY.

Vastera shall indemnify, defend and otherwise hold Ford harmless against any and
all claims brought by any third party against Ford by reason of a failure of
Vastera 's services that are in any way alleged to be the result of the
content, performance or Vastera's use of Information Technology, and Vastera
shall be responsible for all damages and expenses incurred by Ford in assisting
Vastera in defending or settling any such claim.

9.     INDEMNIFICATION PROCEDURES.

With respect to a party's indemnity obligations hereunder with respect to
third-party claims, the following procedures shall apply:

       (a)    NOTICE. Promptly after receipt by any entity entitled to
              indemnification hereunder of notice of the commencement or
              threatened commencement of any civil, criminal, administrative, or
              investigative action or proceeding involving a claim in respect of
              which the indemnitee will seek indemnification pursuant to the
              terms and conditions herein, the indemnitee shall notify the
              indemnitor of such claim in writing. No failure to so notify an
              indemnitor shall relieve it of its obligations under this
              Agreement except to the extent that it can demonstrate damages
              attributable to such failure. Within fifteen (15) days following
              receipt of written notice from the indemnitee 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

                                       5
<PAGE>

            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.

10.    NO TRADEMARK LICENSE

No license is granted to Vastera under this Agreement, by implication or
otherwise, that would allow Vastera to use any existing or future trademark of
Ford or of any member of the Ford Group.

11.    DISPUTE RESOLUTION.

If a material breach occurs or a dispute arises between the parties relating to
this Agreement, the following procedure shall be implemented before either party
pursues other available remedies, 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:

       (a)    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 hereunder or be
              deemed a waiver by a party hereto of any remedies to which such
              party would otherwise be entitled hereunder.

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

       (c)    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.

       (d)    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.

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

                                       6
<PAGE>

       (f)    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.

12.    GENERAL.

12.1   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
plans 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 delays
and shall re-commence performance after the cessation of the Force Majeure
Event.

12.2   BINDING NATURE

This Agreement shall be binding on the parties hereto and their respective
successors and assigns.

12.3   ENTIRE AGREEMENT; AMENDMENT; WAIVER

This Agreement, including the Schedules 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 set forth 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.
