<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.

<PAGE>

            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
<PAGE>

            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.

      9.    Financial Statements. The audited financial statements of the
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
