(a)    Investment Purposes; Compliance With 1933 Act. The Lender is purchasing
the Note for its own account for investment only and not with a view towards, or
in connection with, the public sale or distribution thereof, except pursuant to
sales registered, or exempt from registration, under the 1933 Act and applicable

Agreement. The Lender (i) understands that its investment in the Note involves a
high degree of risk, (ii) is aware that it may be required to bear the economic
risk of its investment for an indefinite period of time and (iii) is able to
bear such risk, including the loss of principal.

(c)    Reliance on Exemptions. The Lender understands that the Note is being
offered and sold to it in reliance on specific exemptions from the registration
requirements of applicable federal and state securities laws, and that the
Borrowers are relying upon the truth and accuracy of, and the Lender’s
compliance with, the representations, warranties and agreements of the Lender
set forth herein in order to determine the availability of such exemptions and
the eligibility of the Lender to acquire the Note.

(d)    Information. The Lender and its advisors, if any, have been furnished
with all materials relating to the business, finances and operations of the
Borrowers and the offer and sale of the Note that have been reasonably requested
by the Lender. The Lender and its advisors, if any, have been afforded the
opportunity to ask all questions of the Borrowers’ management as they have in
their discretion deemed advisable. The Lender has sought such accounting, legal
and tax advice as it has considered necessary to an informed investment decision
with respect to its investment in the Note.

(e)    No Government Review. The Lender understands that no United States
federal or state agency or any other government or governmental agency has
approved or made any recommendation or endorsement of the Note or the fairness
or suitability of an investment in the Note, nor have such authorities passed
upon or endorsed the merits of the offering of the Note.

(f)    Transfer or Resale. The Lender understands that (i) the Note has not been
registered under the 1933 Act or any state securities laws and may not be
offered for sale, sold or otherwise transferred unless either (A) subsequently
registered thereunder or (B) such offer, sale or other transfer is in compliance
with Section 6 below and (ii) no Borrower, nor any other individual or entity,
is under any obligation to register the Note under the 1933 Act or any state
securities laws or to comply with the terms and conditions of any exemption
thereunder.

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

(g)    Legend. The Lender understands that the Note shall bear a restrictive
legend in substantially the following form (the “Legend”):

THE SECURITY REPRESENTED HEREBY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT
OF 1933 OR THE SECURITIES LAWS OF ANY STATE (COLLECTIVELY, THE “LAWS”). THE
SECURITY MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED IN THE
ABSENCE OF EITHER (I) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITY UNDER
THE APPLICABLE LAWS OR (II) AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE
ISSUER, IN FORM, SUBSTANCE AND SCOPE REASONABLY ACCEPTABLE TO THE ISSUER, TO THE
EFFECT THAT SUCH REGISTRATION IS NOT REQUIRED DUE TO AN AVAILABLE EXEMPTION FROM
THE REGISTRATION REQUIREMENTS OF THE APPLICABLE LAWS.

(h)    Authorization; Enforcement. Those Closing Documents to be signed by the
Lender have been duly and validly authorized, executed and delivered by it and
are each valid and binding agreements of the Lender enforceable in accordance
with their respective terms, subject as to enforceability to general principles
of equity and to bankruptcy, insolvency, moratorium and other similar laws
affecting the enforcement of creditors’ rights generally.

existing in good standing under the laws of the state of Delaware and has the
requisite power to own its properties and to carry on its business as now being
conducted.

(j)    Brokers. The Lender has not taken any action that would give rise to any
claim by any individual or entity for brokerage commissions, finder’s fees or
similar payments relating to this Agreement and the transactions contemplated
hereby other than as set forth in the Disbursement Instructions. The Lender
acknowledges that no broker or finder was involved with respect to the
transactions contemplated hereby other than as set forth in Schedule 3(j)
(referred to below) or the Disbursement Instructions.

3.    The Borrowers’ Representations and Warranties. As of the Closing Date,
each of the Borrowers represents and warrants to the Lender, jointly and
severally, as follows:

(a)    Organization and Qualification. Each Borrower (i) is duly organized and
existing in good standing under the laws of its state of formation and (ii) has
the requisite power to own its properties and to carry on its business as now
being conducted and is duly registered as a foreign corporation and is in good
standing in every jurisdiction (other than its state of formation) in which the
nature of its business makes such registration necessary and where the failure
to so register would reasonably be expected to have a Material Adverse Effect.
As used herein, “Material Adverse Effect” means any material and adverse effect
on (i) the assets, liabilities, sales, financial condition, business,
operations, affairs, circumstances or prospects of AETI and its subsidiaries
(taken as a whole) from those reflected in the Financial Information (as defined
below) or from the facts represented or warranted in any of the Closing
Documents (it being recognized by the Lender, however, that projections as to
future events are not to be viewed as facts and that actual results during the
period(s) covered by such projections may differ from the projected results and
that such

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

differences may be material and that no Borrower makes any representation that
such projection will be realized), (ii) the ability of the Borrowers to carry
out their businesses as they are being conducted, or are proposed to be
conducted, at the Closing, (iii) the ability of the Borrowers (taken as a whole)
to meet their obligations under any of the Closing Documents on a timely basis
or (iv) the rights and remedies of the Lender under any of the Closing
Documents. As of the Closing Date, (i) 100% of M&I’s outstanding equity
interests are owned by AETI, (ii) 100% of SCES’ outstanding equity interests are
owned by M&I, (iii) AETI has no subsidiaries other than M&I and a 100% equity
interest in M&I Electric Brazil Sistemas e Servcios en Energia LTDA (“M&I
Brazil”), (iv) M&I has no subsidiaries other than SCES and (v) SCES has no
subsidiaries. No Borrower is a party to any joint venture with any individual or
entity except that M&I holds (A) a 40% joint venture interest in BOMAY Electric
Industries Company, Ltd. (“BOMAY”) pursuant to the Equity Joint Venture Contract
with Baoji Oilfield Machinery Co., Ltd. and AA Energies, Inc. dated March 3,
2006, and any amendments thereto, and (B) a 41% joint venture interest in M & I
Electric Far East PTE Ltd. (“MIEFE”) pursuant to the Joint Venture Agreement
with Oakwell Engineering Limited dated December 3, 1994, and any amendments
thereto, copies of which have been provided to the Lender by the Borrowers.

(b)    Authorization; Enforcement. Each Borrower has the requisite corporate or
limited liability company (as the case may be) power and authority to (i) issue
and sell the Note in accordance with the terms hereof and (ii) enter into and
perform its obligations under those Closing Documents to which it is a party.
Each Borrower’s execution, delivery and performance of those Closing Documents
to which it is a party and its consummation of the transactions contemplated
thereby has been duly authorized in accordance with the current version of its
formation document and the current version of its bylaws or operating agreement,
as applicable (collectively, the “Organizational Documents”) and no other
consent or authorization of a Borrower, its officers, directors, shareholders,
managers, members, or any other individual or entity, is required in connection
therewith, except as expressly stated herein. Each Closing Document to which a
Borrower is a party has been duly and validly authorized, executed and delivered
by it and constitutes its valid and binding obligation enforceable against it in
accordance with the terms of that Closing Document, subject as to enforceability
to general principles of equity and to bankruptcy, insolvency, moratorium and
other similar laws affecting the enforcement of creditors’ rights generally.

(c)    Outstanding Debt. Other than the Note, the Existing Debt (as defined in
Section 4(d) below), or as set forth on the attached Schedule 3(c), there are no
outstanding debt instruments of any Borrower.

(d)    No Integrated Offering. No Borrower, nor any of its Affiliates (as
defined in paragraph (l) below), nor any individual or entity acting on a
Borrower’s behalf, has directly or indirectly made any offers or sales of any
security or solicited any offers to buy any security under circumstances which
would prevent the parties hereto from consummating the transactions contemplated
hereby pursuant to an exemption from registration under the 1933 Act.

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

(e)    No Defaults, Violations or Required Consents. Each Borrower has
previously furnished to the Lender true and correct copies of its Organizational
Documents, in each case as in effect on the Closing Date. Except as set forth on
the attached Schedule 3(e), no Borrower is (i) in violation of its
Organizational Documents or (ii) in default (and no event has occurred which,
with notice or lapse of time or both, would put it in default) under any
Material Contract (as defined paragraph (p) below), nor has there occurred any
event giving any individual or entity (with notice or lapse of time or both) any
rights of termination, acceleration or cancellation of, any Material Contract or
any other agreement or other instrument to which that Borrower is a party,
except for defaults or rights as would not, in the aggregate or individually,
reasonably be expected to have a Material Adverse Effect. Each Borrower has
obtained all consents, authorizations, approvals, and certificates (the lack of
which would have a Material Adverse Effect) in order for it to execute, deliver
and perform any of its obligations under the Closing Documents in accordance
with the terms thereof.

(f)    Financial Information. The Borrowers have made available to the Lender
(i) audited consolidated financial statements of AETI for the fiscal year ended
2015, and (ii) unaudited consolidated financial statements of AETI for the
period ended February 28, 2017 (collectively, the “Financial Information”). The
Financial Information (i) has been prepared in accordance with generally
accepted accounting principles (“GAAP”) consistently applied during the periods
involved except (A) as may be otherwise indicated in the Financial Information
or (B) in the case of interim statements, to the extent they may exclude
footnotes or may be condensed or summary statements and (ii) fairly presents in
all material respects the financial position of AETI as of the dates thereof and
the results of operations and cash flows for the periods then ended (subject to
normal year-end audit adjustments), it being recognized by the Lender, however,
that projections as to future events are not to be viewed as facts and that
actual results during the period(s) covered by such projections may differ from
the projected results and that such differences may be material and that no
Borrower makes any representation that such projection will be realized. Except
as set forth in the Financial Information or the attached Schedule 3(f), a
Borrower has no liabilities, contingent or otherwise, other than liabilities
incurred in the ordinary course of business subsequent to February 28, 2017,
which, individually or in the aggregate, are not materially adverse to the
financial condition, business, operations, properties, operating results or
prospects of that Borrower. No information as to a Borrower that has been
provided by or on behalf of any Borrower to the Lender contains any untrue
statement of a material fact or omits to state any material fact required to be
stated therein in order to make the statements therein, in the light of the
circumstances under which they were made, not materially misleading.

(g)    Absence of Certain Changes; Bankruptcy. From the date of the latest
Financial Information through the Closing Date, there has been no Material
Adverse Effect. No Borrower has taken any steps, or currently has any reasonable
expectation of taking any steps, to seek protection pursuant to any bankruptcy
law, nor does any Borrower have any knowledge that its creditors intend to
initiate involuntary bankruptcy proceedings.

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

(h)    Absence of Litigation. Except as set forth on the attached Schedule 3(h),
there is no action, suit, proceeding, inquiry or investigation before or by any
court, arbitrator, public board or Governmental Authority pending or, to the
knowledge of any Borrower, threatened against or affecting any Borrower wherein
an unfavorable decision, ruling or finding would be reasonably expected to have
a Material Adverse Effect or which would be reasonably expected to materially
and adversely affect the validity or enforceability of, or the authority or
ability of any Borrower to perform its obligations under, any of the Closing
Documents.

(i)    Corrupt Business Practices. No Borrower, nor any officer, director,
shareholder, manager, member, employee or agent of any Borrower, nor, to any
Borrower’s knowledge, any other individual or entity acting on behalf of any
Borrower has, in the course of his, her or its actions, (i) used any Borrower’s
assets for any unlawful contribution, gift, entertainment or other unlawful
expense relating to political activity, (ii) violated any provision of the
United States Foreign Corrupt Practices Act of 1977, as amended, or (iii) made,
directly or indirectly, any bribe, rebate, payoff, influence payment, kickback
or other unlawful payment (from a Borrower’s funds or otherwise) to any foreign
or domestic government official or employee.

(j)    Brokers; No General Solicitation. No Borrower has taken any action that
would give rise to any claim by any individual or entity for brokerage
commissions, finder’s fees or similar payments relating to this Agreement and
the transactions contemplated hereby other than as set forth on the attached
Schedule 3(j) or as set forth in the Disbursement Instructions. No Borrower, and
no other individual or entity, has conducted any “general solicitation,” as
described in Rule 502(c) under Regulation D, with respect to the Note.

(k)     Status of Real Property and Other Assets.

(i)    The Owned Property in the only real property that is owned by any
Borrower. The Owned Property is not subject to any lease, sublease, or tenancy
and M&I has good and indefeasible title to the Owned Property, free of all liens
and encumbrances except for “Permitted Liens” as defined in M&I’s Security
Agreement. The attached Schedule 3(k) sets forth a complete list of all leases
by any Borrower (each, a “Lease”) as lessee of any real property (the “Leased
Property”). The Borrowers have provided the Lender with all documentation listed
on Schedule 3(k) which is true and correct in all material respects, and such
documentation is the complete agreement of the parties to each Lease in all
material respects. Each Lease is in full force and effect and the applicable
Borrower has undisturbed possession of the Leased Property. There is no material
default on the part of any party to any Lease or any event or condition which
(with notice or lapse of time, or both) would constitute a material default
under any Lease. There are no lawsuits or proceedings at law or in equity, in
arbitration, or before any Governmental Authority, that are pending or, to the
knowledge of any Borrower, threatened against the Owned Property or any Leased
Property which would in any way materially and adversely affect the right to use
the Owned Property or the right to use any Leased Property pursuant to its
Lease.

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

(ii)    Except for Permitted Liens (as defined in the Security Agreements) or as
otherwise described in the applicable Security Agreement or Schedule 3(k), each
Borrower has good and marketable title to, or valid right to use, each of those
assets that is material to its business, free and clear of all liens, claims,
restrictions and other encumbrances.

(l)    Affiliate Transactions. As to each existing agreement or transaction
between a Borrower and any Affiliate of that Borrower (other than another
Borrower), the terms of that agreement or transaction are consistent with market
rates in effect at the time the agreement or transaction was entered into;
provided, however, that this provision shall not apply to (i) transactions
between or among the Borrowers, (ii) loans or advances to employees, officers,
managers, members, shareholders, directors or agents that are permitted under
Section 4(aa) hereof, (iii) customary director, officer and employee
compensation and severance (including bonuses) and other benefits (including
retirement, health, stock options and other benefit plans) in the ordinary
course of business, (iv) Distributions permitted under Section 4(k) hereof,
(v) transactions which would not, individually or in the aggregate, exceed
$10,000 in any fiscal year, except on terms consistent with market rates in
effect at the time, (vi) transactions permitted under Section 4(jj) hereof, and
(vii) increases in the salary or consideration payable to any Affiliate from
that paid on the Closing Date, so long as (A) the Affiliate is entitled to such
increase pursuant to a written agreement that was in effect on the Closing Date
or (B) such increase was specified in a Budget. For purposes of this Agreement,
the term “Affiliate” means, with respect to a specific individual or entity, any
other individual or entity that directly or indirectly controls, or is
controlled by, or is under common control with, the specified individual or
entity. For purposes of that definition, “control,” means the possession,
directly or indirectly, of the power to direct or cause the direction of the
management and policies of such individual or entity, whether through the
ownership of voting equity, by contract or otherwise.

(m)     Insurance. Each Borrower’s insurance coverage with respect to its
properties, assets and business is reasonable and customary for entities engaged
in similar lines of business in its geographic region and is in full force and
effect. Such coverage includes (i) general liability insurance of at least
$2.0 million, with a $10.0 million umbrella policy, and (ii) property and
casualty insurance in an amount at least equal to the Owned Property Appraised
Value (as defined below).

(n)     Solvency. Each Borrower is solvent as of the Closing Date and shall not
become insolvent as a result of the consummation of the transactions
contemplated by this Agreement. After giving effect to the transactions
contemplated by this Agreement, each Borrower (i) shall be able to pay its debts
as they become due and its property shall have a fair saleable value greater
than the amounts required to pay its debts (including a reasonable estimate of
the amount

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

of all contingent liabilities) and (ii) shall have adequate capital to carry on
its businesses. No transfer of property is being made and no obligation is being
incurred in connection with the transactions contemplated by this Agreement with
the intent to hinder, delay or defraud any Borrower’s present or future
creditors.

(o)    Licenses and Governmental Compliance. Except as described on the attached
Schedule 3(o), each Borrower’s business and the Owned Property and the Leased
Property are being operated in material compliance with all applicable laws,
ordinances and regulations of every federal, state, county, municipal or other
governmental authority or quasi-public authority (including, but not limited to,
any taxing authority and those with respect to environmental and consumer
protection matters) having jurisdiction over its assets or operations (each a
“Governmental Authority;” collectively, the “Governmental Authorities”), except
for possible violations which neither singly nor in the aggregate would
reasonably be expected to have a Material Adverse Effect. Except as described on
Schedule 3(o), each Borrower is in good standing with all applicable
Governmental Authorities and holds all permits, licenses, approvals or other
authorizations from such Governmental Authorities as are reasonably necessary or
appropriate for the operation of its businesses, its Owned Property and/or its
Leased Property.

(p)    Status of Material Contracts. As to each of those agreements to which a
Borrower is currently a party which, if terminated or placed in default, would
reasonably be expected to have a Material Adverse Effect (a “Material
Contract”), the Borrowers represent and warrant that, except as described on the
attached Schedule 3(p), (i) no termination or default has been declared by that
Borrower or any other party thereto, (ii) to the Borrowers’ knowledge, no event
has occurred which, with notice or lapse of time or both, would result in a
termination or default thereunder, and (iii) a Borrower’s execution and delivery
of, and performance under, any Closing Document to which it is a party will not
result in the termination of, or a default under, any Material Contract.

(q)    Material Intellectual Property. Each Borrower owns or has the right to
use all of the patents, trademarks, service marks, copyrights, trade secrets,
know-how and other intellectual property that is material to that Borrower’s
business, the loss of which could reasonably be expected to have a Material
Adverse Effect.

(r)     No Investment Company; Other Restrictions. No Borrower is (i) an
“investment company” or a company “controlled” by an “investment company” within
the meaning of the Investment Company Act of 1940, as amended, or (ii) subject
to any federal, state or local statute or regulation limiting its ability to
incur indebtedness. No Borrower is engaged principally, or as one of its
important activities, in the business of extending credit for the purpose of
purchasing or carrying any “margin stock” within the meaning of Regulation U of
the Board of Governors of the U.S. Federal Reserve System (the “Board”). None of
the net Purchase Price will be used to purchase or carry margin stock, extend
credit to others to purchase or carry margin stock, or in any other manner that
will violate, or be inconsistent with, the provisions of Regulation T, U or X or
any other regulation of the Board.

(s)    Industry Certifications. As of the Closing, the Borrowers hold the third
party industry certifications listed on the attached Schedule 3(s).

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

(t)    Series A Convertible Preferred Stock. JCH Crenshaw Holdings, LLC
(“Crenshaw”) is the sole owner of AETI’s Series A Convertible Preferred Stock
(the “Preferred Stock”) and no material default by AETI as to any of its
representations, warranties or covenants in the Securities Purchase Agreement by
and between AETI and Crenshaw dated as of April 13, 2012, is currently in
existence or is reasonably expected to occur.

4.    Covenants of the Parties.

(a)    Commercially Reasonable Efforts. Each party shall use commercially
reasonable efforts to timely satisfy each of the conditions to be satisfied by
it as provided in Sections 6 and 7 below. No party shall intentionally perform
or fail to perform any act that, if performed or omitted to be performed, would
prevent or excuse the performance of this Agreement or any of the transactions
contemplated hereby.

(b)    Expense Reimbursement. Upon receipt from the Lender of adequate
documentation, the Borrowers agree, jointly and severally, to (i) pay, or
reimburse the Lender for, all reasonable actual out-of-pocket fees and expenses
(including business, accounting, legal, appraisal and post-Closing monitoring)
incurred by the Lender in connection with this Agreement and the other Closing
Documents and any amendments thereto, regardless of whether they are incurred
before or after the Closing (collectively, the “Expenses”), (ii) pay all filing
fees required in connection with the transactions contemplated by the Closing
Documents and (iii) provide advances against the Expenses in such amounts as the
Lender may reasonably request from time-to-time. The Lender acknowledges that
$40,000.00 (the “Expense Deposit”) has been received on behalf of the Borrowers
to be applied toward the Expenses. Any unused portion of the Expense Deposit
shall be returned to the Borrowers within ten (10) days after written request.
The obligations in this paragraph shall survive the termination of this
Agreement and the payment of the Note.

(c)    Status; Taxes. Until the Obligations (as defined in the Security
Agreements) have been paid in full, each Borrower shall (i) be duly qualified as
a foreign entity and in good standing in every jurisdiction (other than its
state of formation) in which the nature of its business makes such qualification
reasonably necessary and where the failure to so qualify would reasonably be
expected to have a Material Adverse Effect, (ii) maintain its existence in good
standing in its state of formation, (iii) not change its name unless it gives at
least thirty (30) days prior written notice of such change to the Lender and
(iv) pay all taxes before they become delinquent, except for taxes that are
reasonably disputed or which, if not paid, would not reasonably be expected to
have a Material Adverse Effect.

(d)    Use of Proceeds. The Borrowers shall use the net Purchase Price only
(i) to repay the indebtedness (including any accrued and unpaid interest
thereon) described on the attached Schedule 4(d) (the “Existing Debt”) or
(ii) for working capital and general business purposes.

(e)    Restrictions on Debt Payments. Until the Obligations have been paid in
full, a Borrower shall not make, nor shall it cause or allow any subsidiary to
make, any payment on or with respect to any debt in existence on the Closing
Date except (i) as specified in paragraph (d) above, (ii) trade payables,
purchase money debt, capital leases and other obligations incurred in the
ordinary course of business, (iii) any debt that is subordinated to the Note
(provided that such debt is paid in accordance with any subordination or other
agreement entered into with the Lender with respect thereto), (iv) debt owed
from one Borrower to another Borrower, (v) any debt that is listed on Schedule
4(aa), or (vi) any debt that is listed on Schedule 3(c) or is otherwise secured
by Permitted Liens or liens that are otherwise permitted by that Borrower’s
Security Agreement.

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

(f)    Creation of Post-Closing Debt. Subject to Section 4(jj) hereof, until the
Obligations have been paid in full, after the Closing Date no Borrower shall
incur, nor shall it cause or allow any subsidiary to incur, any debt unless such
debt (i) is non-amortizing, not currently payable, subordinated to the Note by a
subordination or other agreement on terms reasonably acceptable to the Lender,
and has a maturity date that is at least ninety-one (91) days after the maturity
date of the Note, (ii) consists solely of trade payables, purchase money debt
that is approved in writing by the Lender (which approval shall not be
unreasonably withheld, conditioned or delayed), capital leases approved in
writing by the Lender (which approval shall not be unreasonably withheld,
conditioned or delayed) or other obligations incurred in the ordinary course of
business or (iii) is due and owing to the Lender.

(g)    Minimum Monthly Cash, Revenue, EBITDA, DSCR and Debt/EBITDA Ratio. Until
the Obligations have been paid in full, beginning on the first day of the month
in which the Closing Date occurs and as of the first day of each calendar month
thereafter, AETI, on a consolidated basis, shall (i) maintain an average minimum
balance of cash and cash equivalents, (ii) maintain minimum monthly revenue

debt/EBITDA ratio, in each case as set forth on the attached Schedule 4(g) for
the month specified (subject to periodic increase pursuant to paragraph (h)(iv)
below). For purposes of Schedule 4(g), DSCR shall mean AETI’s consolidated
trailing twelve-month EBITDA divided by its trailing twelve-month interest
expense. For purposes of Schedule 4(g), “debt/EBITDA ratio” shall mean, as of
any date, an amount equal to the current balance of the Note plus any accrued
and unpaid interest thereon divided by AETI’s consolidated trailing twelve-month
EBITDA.

(h)    Financial and Other Information. Until the Obligations have been paid in
full:

(i)    Within fifteen (15) business days after the end of each calendar month,
the Borrowers shall provide the Lender with a report, electronically or in

year and comparisons to budgets prepared by the Borrowers, (C) AETI’s
consolidated trailing twelve-month revenue and EBITDA and (D) such other
financial or business information with regard to the Borrowers and/or any
subsidiary thereof as the Lender may reasonably request, all in a format that is
mutually agreeable to the Borrowers and the Lender. The monthly statements shall
be accompanied by a certificate from AETI’s principal financial officer and/or
principal executive officer certifying that (A) the monthly financial statements
are accurate in all material respects, (B) each Borrower is in compliance with
each covenant set forth in the Closing Documents that applies to it, (C) no

financial institutions or third party lenders, or if such is not the case,
specifying such non-compliance, Event of Default or other event of default and
the steps being taken to remedy the same. The monthly statements shall be
accompanied by (A) a brief discussion and analysis of any material and adverse
changes in the Borrowers’ financial condition and/or results of operations
compared to the prior month and (B) a description of any pending or, to any
Borrower’s knowledge, threatened material litigation or other legal action
involving a Borrower or any of its subsidiaries.

(ii)    Unless otherwise notified by the Lender, during each calendar month the

mutually agreeable place and time.

(iii)    Within ninety (90) days after the end of each fiscal year (or when
furnished to any officer, director, shareholder, member, manager, lender or
other third party, if earlier), the Borrowers shall provide the Lender with a
report that includes a consolidated balance sheet with respect to AETI as of the
end of such fiscal year and related consolidated statements of income,
shareholders’ equity and cash flow with respect to AETI for such fiscal year,
with accompanying notes. Beginning with AETI’s fiscal year 2017 and continuing
for all subsequent years, such report shall be audited by Ham, Langston &
Brezina LLP or any other auditor reasonably acceptable to the Lender. Each
report shall be accompanied by corresponding figures for the preceding fiscal
year in a form reasonably satisfactory to the Lender.

(iv)    At least forty-five (45) days prior to the commencement of each fiscal
year (commencing with fiscal year 2019), the Borrowers shall provide the Lender
with a comprehensive annual budget (the “Budget”), which shall include annual
consolidated and consolidating budgets prepared on a monthly basis for AETI for
such fiscal year (displaying anticipated statements of income, shareholders’
equity, changes in financial position and balance sheets and containing such
internal narrative as is appropriate). In addition, the Budget shall include a
capital expenditure plan which shall be presented to each Borrower’s management
for approval within forty-five (45) days prior to the commencement of each
fiscal year. Each Budget and capital expenditure plan, and any changes thereto,
shall be subject to the approval of the Lender, which approval shall not be
unreasonably withheld, conditioned or delayed. Based on the above information,
at the appropriate time the Lender shall provide the Borrowers with a revised
Schedule 4(g) for the fiscal year 2019.

(v)    All financial reporting provided to the Lender shall be prepared in
accordance with GAAP consistently applied in the period covered thereby and
shall be in a form reasonably satisfactory to the Lender.

(i)    Capital Expenditures. Until the Obligations have been paid in full,
without the written consent of the Lender (which consent shall not be
unreasonably withheld, conditioned or delayed), a Borrower shall not, nor shall
any Borrower cause or allow any subsidiary to, make

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

any expenditures for fixed or capital assets if, after giving effect thereto,
the aggregate of all such expenditures among the Borrowers and any of their
subsidiaries would exceed $1,000,000 during 2017 or any calendar year thereafter
(the “Annual CapEx Limit”), in each case net of the cash proceeds received
during such time period from the permitted sale of any fixed or capital assets.

(j)    Transfer of Assets; Leasebacks; Management Fees. Until the Obligations
have been paid in full, without the written consent of the Lender (which consent
shall not be unreasonably withheld, conditioned or delayed), a Borrower shall
not, nor shall any Borrower cause or allow any subsidiary to, enter into any
arrangements, directly or indirectly, with any individual or entity, whereby
that Borrower or its subsidiary shall (i) sell or transfer any asset and then
rent or lease (as lessee) that asset for substantially the same purpose or
purposes as the asset was used prior to sale or transfer, (ii) pay any
management fee or similar type of fee to any individual or entity, or (iii) sell
or otherwise transfer any material asset, whether now owned or hereafter
acquired, except for (A) the sale, lease or other disposition of inventory in
the ordinary course of business, (B) the disposition of cash or liquid
investments in the ordinary course of business, (C) dispositions of obsolete or
worn-out equipment or other assets in the ordinary course of business,
(D) dispositions of assets that a Borrower determines in good faith are no
longer used or useful in the business of such Borrower, (E) the abandonment or
other disposition of patents, trademarks and copyrights that, in the reasonable
judgment of Borrowers, should be replaced or are no longer economically
practicable to maintain or useful in the conduct of the business of Borrowers,
(F) assignments and licenses of patents, trademarks or copyrights of any
Borrower in the ordinary course of business, (G) the disposition of any asset
required under applicable law, (H) leases of real or personal property in the
ordinary course of business, and (i) the expiration or termination of any lease
of real or personal property in the ordinary course of business.

(k)    Dividends, Distributions, Issuances and Redemptions. Until the
Obligations have been paid in full, a Borrower shall not (i) declare, authorize
or pay any dividend or distribution on any of its equity interests,
(ii) purchase, redeem or otherwise acquire for value any of its equity
interests, (iii) return any capital to its shareholders or members, (iv) make
any distribution of its assets to its shareholders or members or (v) cause or
allow any subsidiary to take any of the foregoing actions with respect to its
equity interests (collectively, the “Distributions”). As used in this Section,
the “equity interests” of AETI shall include (but are not limited to) the
Preferred Stock. The foregoing notwithstanding, (i) AETI shall be permitted to
pay Distributions on the shares of Preferred Stock that are outstanding at the
Closing as provided in the Preferred Stock Letter (as defined below) and (ii) a
Distribution by a Borrower to the owners of its equity interests shall be
permitted if it is for the sole purpose of providing such owners with funds to
pay actual cash federal and/or state taxes arising out of their equity interests
in that Borrower and no Event of Default under the Note is continuing or would
result therefrom.

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

(l)    Collateral Coverage Ratio.

(i)    Until the Obligations have been paid in full, the Borrowers shall not at
any time permit the collateral coverage ratio (“CCR”), calculated on a trailing
three-months basis at orderly liquidation value, to be less than the amount
shown on Schedule 4(g) (subject to periodic increase as provided in paragraph
(h)(iv) above). For purposes of this paragraph, CCR shall mean, as of any date,
an amount equal to the ratio of (A) the sum of (1) non-restricted cash held in
account(s) that are subject to a DACA (as defined in paragraph (cc) below), plus
(2) non-restricted short-term investments, plus (3) the value of the Eligible
Inventory (as defined below), plus (4) the value of the Eligible Accounts
Receivable (as defined below), plus (5) the value of the existing equipment (as
defined below), plus (6) the value of the Owned Property (collectively, the
“Ratio Collateral”), all determined as of the end of each calendar month in
which the Note remains outstanding (beginning at Closing) on a consolidated
basis in accordance with GAAP and reflected on AETI’s consolidated balance
sheet, to (B) the unpaid principal amount of the Note.

(ii)    For purposes of clause (i) above, the term “Eligible Inventory” means
the aggregate amount of all inventory valued at the lower of cost or market on
an average cost basis net of all promotional or any other allowances or
discounts which is at all times owned and held for sale (and not held for lease)
by a Borrower and in which at all times the Lender has an enforceable and duly
perfected first priority and exclusive security interest and for which no
account has arisen; provided, however, that the following shall not constitute
“Eligible Inventory”: (A) any inventory which has been shipped, delivered,
provided to, purchased or sold by a Borrower on a bill and hold, consignment
sale, guaranteed sale, or sale or return or other similar basis, or which has
been returned to a Borrower after sale thereof or which the Lender reasonably
determines to be other than first quality, defective, unmerchantable, obsolete,
slow-moving, or held for more than 180 days, (B) any inventory which is not
located in the United States of America, (C) any inventory which consists of

materials) used or consumed in a Borrower’s business, or consisting of finished
goods which for whatever reason do not conform to the order pursuant to which
those finished goods were ordered, (D) any inventory which is produced in
violation of the Fair Labor Standards Act and is subject to the so-called “hot
goods” provisions contained in 29 USC 215(a)(i), or which fails to comply with
any standard imposed by any Governmental Authority having authority over the
disposition, manufacture, or use of that inventory, (E) any inventory which is
covered by a Document (as defined in the applicable Uniform Commercial Code)
unless the Document is in the possession and control of the Lender, (F) any
inventory which is in the possession of any bailee unless that inventory,
together with all proceeds and products thereof, has been described in
(1) appropriately signed financing statements naming the bailee as consignee,
the applicable Borrower as consignor, and the Lender as assignee of the
consignor, having been duly filed (before the bailee receives possession of any
such inventory) with all filing officers with whom filing is required in order
to perfect the Lender’s security interest therein, and being otherwise in form
and substance satisfactory to the Lender, (2) a written notification which shall
have been received (within five years before the bailee receives possession of
any such inventory) by each holder of a security interest in property of the
bailee, and state that the applicable Borrower expects to deliver goods on
consignment to the bailee, and (3) a Document which shall have been duly issued
by the bailee in the name of the Lender and which shall comply with clause
(E) above and otherwise be in form and substance satisfactory to the Lender,
(G) any inventory which is in-transit or which, unless in the possession of a
bailee and not ineligible under clause (F) above, is located in or upon any real
estate that is not owned in fee simple absolute by the applicable Borrower free
of all encumbrances except any in favor of the Lender or with respect

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

to which the applicable Borrower does not have exclusive rights of possession
under a lease which is reasonably acceptable to the Lender, unless (1) the
Lender shall have been granted an enforceable and duly perfected first priority
mortgage lien on that real estate pursuant to a writing in form and substance
satisfactory to the Lender or (2) each owner or encumbrancer of that real estate
shall have executed and delivered to the Lender a writing pursuant to which the
owner or encumbrancer, as the case may be, shall have, among other things,
consented to the Lender’s security interest in that inventory and all proceeds
and products thereof, and shall have granted the Lender (or one or more other
individuals or entities selected by the Lender) the right to enter upon such
real estate and remove all or any part of that property therefrom without
liability except to pay for the repair of any physical damage to such real
estate that is proximately caused by any such removal, (H) any inventory which
is subject to any lease or other title retention contract, (I) any inventory
which is subject to any mortgage, security interest, or other lien securing
payment or performance of any obligation other than to the Lender, (J) any
inventory which is described in any financing statement naming any individual or
entity other than the Lender as the secured party of record, except for
Permitted Liens, (K) any inventory which is advertising materials or supplies,
(L) any inventory which is subject to any royalty, copyright, trademark, trade
name, or licensing arrangement, or any law, rule, or regulation that could limit
or impair the Lender’s ability to exercise its rights with respect to such
inventory or (M) any inventory which has been purchased from any Affiliate to
the extent the book value exceeds the original cost to such Affiliate. All
determinations as to whether any inventory is Eligible Inventory shall be made
by the Lender in its commercially reasonable discretion.

first-priority perfected security interest in favor of the Lender, (B) that is
not unpaid more than 90 days from its due date, (C) that was billed in the
ordinary course of business (provided, however, that failure to bill on specific
dates as provided in customer terms and conditions or other instances where the
actions are immaterially different from stated billing practices will not be
deemed to be outside of the ordinary course of business), (D) that has resulted
from the sale of goods or the performance of services by a Borrower without any
further obligation on the part of that Borrower to service, repair, or maintain
any such goods sold other than pursuant to any applicable warranty, (E) that has
no conditions which must be satisfied before the applicable Borrower is entitled
to receive payment of the account receivable (with any accounts receivable
arising from COD sales, consignments or guaranteed sales being unacceptable),
(F) where the debtor does not claim any defense to payment of the account
receivable, whether well-founded or otherwise, (G) where there is no legitimate
right of set-off, counterclaim, allowance, adjustment, defense or discount

defense or discount), (H) that represents a genuine obligation of the debtor for
goods sold to and accepted by the debtor, or for services performed for and
accepted by the debtor (with any credit balances that exist in favor of the
debtor to be deducted from the account balance), (I) that represents retainage a
Borrower would be entitled to receive under the applicable contract if such
contract was canceled on the date of the determination of the CCR, (J) that does
not include the amount of any finance or service charges payable by the debtor
(with any finance or service charges that are included being deducted from the
account balance), (K) that is owned by a Borrower free and clear of liens,
except Permitted Liens, (L) where the applicable Borrower is not prohibited by
applicable state laws from bringing an action to enforce the debtor’s obligation
to pay the account receivable (with that Borrower having taken all appropriate
actions to ensure access to the courts of the state where

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

the account debtor is located, including, where necessary, the filing of a
notice of business activities report or other similar filing with the applicable
state agency or the qualification by that Borrower as a foreign entity
authorized to transact business in such state), (M) where the debtor is not an
employee or Affiliate of a Borrower, a member of the family of any employee or
Affiliate of a Borrower, or an entity which has common management with a
Borrower, (N) where the debtor obligated on the account has not suspended its
business, made a general assignment for the benefit of creditors, or failed to
pay debts generally as they come due, (O) where the account is not the
obligation of a debtor who is in default on 20% or more of the accounts
receivable upon which such debtor is obligated, (P) where the account does not
arise from the sale of goods which remain in a Borrower’s possession or under a
Borrower’s control, (Q) where the account is not evidenced by a promissory note
or chattel paper, nor is the debtor obligated to a Borrower under any other
obligation which is evidenced by a promissory note or chattel paper, (R) where
the dollar amount of the accounts receivable which are the obligations of a
single debtor does not exceed 20% of the accounts receivable of a Borrower (with
the amount of any such excess to be excluded), (S) that did not arise from a
sale of goods or services in which the performance of a Borrower or any of its
subsidiaries has been bonded by an issued performance bond, (T) as to which
management of a Borrower does not have knowledge that the debtor has claimed
that such account receivable is subject to set-off, counterclaim, defense,
allowance or adjustment (but solely to the extent of such set-off, counterclaim,
defense, allowance or adjustment), (U) as to which management of a Borrower does
not have actual knowledge that the account debtor is the subject of bankruptcy

the Lender, in its commercially reasonable discretion, (Y) that is not an
unbilled accounts receivable that consists of work or tasks that have been
completed but has not yet been billed to the customer and (Z) that includes any
amount which constitutes retainage. The term “Eligible Accounts Receivable”
shall expressly (i) include accounts that are invoiced or billed on progress
billing or similar basis including, without limitation, accounts which are
billed incrementally on a basis of milestones achieved or percentage of work
completed or services performed, so long as such accounts arise in the ordinary
course of business and (ii) exclude costs and estimated earnings in excess of
billing on contracts that are not yet completed.

(iv)    For purposes of clause (i) above, the “value of the existing equipment”

Value, including monthly capital expenditures, less monthly depreciation as
calculated in accordance with GAAP.

(v)    For purposes of clause (i) above, the “value of the Owned Property” shall
initially be 0.75x its appraised value of $6.9 million at Closing (the “Owned
Property Appraised Value”). Thereafter, the monthly value of the Owned Property
shall be the current Owned Property Appraised Value less monthly depreciation as
calculated in accordance with GAAP. Each Borrower acknowledges that (i) the
Lender currently intends to re-appraise the value of the Owned Estate on an
annual basis and (ii) each re-appraised value shall become the new Owned
Property Appraised Value for purposes of the foregoing.

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

(vi)    Each Borrower acknowledges that the Lender currently intends to examine
the Borrowers’ compliance with the Ratio Collateral requirements on an annual
basis, although the Lender may, in its sole discretion, adjust the frequency of
such examinations which, in any case, shall not exceed two (2) times in any
12-month period (not including any examinations made at a time when an Event of
Default has occurred and is continuing). Such examinations shall be at the
Borrowers’ expense; provided, however, that absent the continuation of an Event
of Default under the Note, any examinations other than the annual examination
shall be at the Lender’s expense. Each Borrower shall (A) fully cooperate with
the Lender in connection with any examination of the Ratio Collateral,
(B) permit the Lender, upon commercially reasonable notice and during regular
business hours, to have such access to the books, records and premises as the
Lender may reasonably require in connection with any such examination and
(C) instruct and permit its customers and suppliers to provide such information
to the Lender as the Lender may reasonably require in connection with any such
examination (and each Borrower hereby consents to any inquiries that the Lender
may make of such customers and suppliers in connection with any such
examination).

(m)    Other Information. Until the Obligations have been paid in full, each
Borrower shall promptly provide the Lender with any reports, management letters
or other information that are created or received concerning material aspects of
its and/or any subsidiary’s operations and financial affairs to the extent not
otherwise provided to the Lender. Within seven (7) business days, a Borrower
shall provide the Lender with such other information and financial data
concerning itself or any subsidiary as the Lender may reasonably request,
including, but not limited to, copies of the minutes of management meetings and
any resolutions adopted by the managing body.

(n)    Payment of Administrative Fee. For each calendar quarter in which the
Note is outstanding that commences after April 1, 2017, the Borrowers shall
collectively pay to the Lender an aggregate administrative fee of $5,000.00. The
quarterly payment shall be made at the same time as the last monthly interest
payment that is due on the Note in that calendar quarter.

(o)    Acquisition of Subsidiaries. In the event that a Borrower intends to form
or acquire any subsidiary at any time prior to the full payment of the
Obligations, that Borrower shall promptly notify the Lender in writing of such
pending formation or acquisition. Upon the Lender’s request, at the time of such
formation or acquisition the Borrower shall (i) cause such subsidiary to execute
a joinder agreement, pursuant to which it becomes a co-borrower under this
Agreement and the Note, and an appropriate form of a Security Agreement and
(ii) provide, or cause such subsidiary to provide, the Lender with such other
agreements and documents as the Lender may reasonably request in connection
therewith. In each case, the documentation to be provided pursuant to this
paragraph shall be in a form reasonably acceptable to the Lender.

(p)    Acquisition of Real Property; Security Interests. Until the Obligations
have been paid in full, a Borrower shall not acquire, nor shall a Borrower cause
or allow any subsidiary to acquire, an ownership interest in any real property
without the Lender’s prior written consent, which shall not be unreasonably
withheld, conditioned or delayed. In the event that any acquisition of an
ownership interest in real property is permitted by the Lender, concurrent with
such acquisition the applicable Borrower shall, or shall cause its acquiring
subsidiary to, (i) grant the Lender a first-priority security interest therein
by means of a mortgage or deed of trust substantially similar to the Deed of
Trust and (ii) enter into or provide such other documentation (including, but
not limited to, an agreement substantially similar to the Environmental

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

Agreement, a title insurance policy or endorsement to the existing title
insurance policy, and an appropriate amendment to the Deed of Trust to ensure
cross-default with the new deed of trust) as the Lender may reasonably require.

(q)    Sale or Discount of Accounts Receivable. Until the Obligations have been
paid in full, a Borrower shall not, nor shall any Borrower cause or allow any
subsidiary to, discount or sell (with or without recourse) any of its accounts
receivable, except in connection with the collection or enforcement thereof in
the ordinary course of business.

(r)    Indemnification. Upon demand, each Borrower shall indemnify the Lender
and its Affiliates with respect to, and defend and hold the Lender and its
Affiliates harmless against, any loss, damage, liability, cost or expense
(including, but not limited to, reasonable attorney’s fees and costs of
investigation) arising out of or in connection with any claim or cause of action
that is brought or threatened in writing against the Lender and/or its
Affiliates by any individual or entity (other than a Borrower) as a result of
the Lender entering into this Agreement or any of the other Closing Documents
and/or performing its obligations hereunder or thereunder, except to the extent
such loss, damage, liability, cost or expense arises out of, has resulted from
or is in connection with (i) the gross negligence or willful misconduct of the
Lender or its Affiliates or (ii) any breach by the Lender of this Agreement or
any of the other Closing Documents. The obligations in this paragraph shall
survive the termination of this Agreement and the payment of the Note.

(s)    Inspection of Property. Until the Obligations have been paid in full,
each Borrower shall permit any representative designated by the Lender, upon
reasonable notice and during normal business hours, to (i) visit and inspect any
of the properties of that Borrower or any subsidiary thereof, (ii) examine the
financial records of that Borrower or any subsidiary thereof and make copies
thereof or extracts therefrom and (iii) discuss the affairs, finances and
accounts of that Borrower or any subsidiary thereof with its management, key
employees and independent accountants. The applicable Borrower shall reimburse
the Lender for all commercially reasonable costs and expenses incurred by it in
connection with one inspection per year plus any other inspections that are made
during the year when an Event of Default has occurred and is continuing, with
the Lender to bear the costs and expenses of any additional inspections.

(t)     Unfunded Liabilities - ERISA. Until the Obligations have been paid in
full, a Borrower shall not incur any liability or tax under Section 4971 of the
Internal Revenue Code of 1986, as amended (the “Code”) in respect of an
accumulated funding deficiency (or obtain any waiver under Section 412(d) of the
Code or Section 303 of the Employee Retirement Income Security Act of 1974, as
amended (“ERISA”)) or incur any material liability to the Pension Benefit
Guaranty Corporation in connection with any employee benefit plan. A Borrower
shall not cause or allow, or permit any subsidiary to cause or allow, any
Reportable Event (as defined in Title IV of ERISA) to occur or continue with
respect to any employee benefit plan.

(u)    Affiliate Transactions. Until the Obligations have been paid in full, no
Borrower shall (i) enter into any transaction(s) with any Affiliate other than

officers, managers, members, shareholders, directors or agents that are
permitted under Section 4(aa) hereof, (C) customary director, officer and
employee compensation and severance (including bonuses) and other benefits
(including retirement, health, stock options and other benefit plans) in the
ordinary course of business, (D) Distributions permitted under Section 4(k)
hereof, (E) transactions permitted under Section 4(jj) hereof, and
(F) transactions which would not, individually or in the

market rates in effect at the time, (ii) increase the salary or consideration
payable to any Affiliate from that paid on the Closing Date unless (A) the
Affiliate is entitled to such increase pursuant to a written agreement that was
in effect on the Closing Date or (B) such increase was specified in a Budget, or
(iii) cause or allow any subsidiary to take any of the foregoing actions.

(v)    Insurance. Until the Obligations have been paid in full, each Borrower
shall at all times (i) keep its business and assets, and the business and assets
of any subsidiary, insured against such liabilities, losses and damage as are
customarily and ordinarily insured against by owners of similar businesses in
its geographic region through such insurers, and on such terms of coverage, as
are reasonably acceptable to the Lender and (ii) cause its insurance policies
and those of any subsidiaries to name the Lender as an additional insured or
beneficiary thereunder (or include a lender loss contract endorsement payable in
favor of the Lender) and provide that such policies may not be canceled without
at least thirty (30) days prior notice to the Lender. Such insurance coverage
shall at all times include (i) business interruption insurance (after the
deadline specified in Section 4(kk) below), (ii) general liability insurance of
at least $2.0 million, with a $10.0 million umbrella policy, and (iii) property
and casualty insurance in an amount at least equal to the Owned Property
Appraised Value. Until the Obligations have been paid in full, upon the Lender’s
reasonable request, a Borrower shall promptly provide the Lender with (i) a
certificate of insurance evidencing the effectiveness of each type of insurance
required to be maintained pursuant to this paragraph and (ii) a copy of each
applicable insurance policy.

(w)    Notice of Material Adverse Effect. Until the Obligations have been paid
in full, AETI shall promptly notify the Lender in writing of the occurrence of a
Material Adverse Effect.

paid in full, each Borrower’s business, and those of its subsidiaries, and its
Owned Property and/or Leased Property shall at all times be operated in
compliance with all applicable laws, ordinances and regulations of all
applicable Governmental Authorities, except for possible violations which alone
or in the aggregate would not reasonably be expected to have a Material Adverse
Effect. Until the Obligations have been paid in full, each Borrower and each of
its subsidiaries shall hold all licenses and permits from such Governmental
Authorities as are necessary or appropriate for the operation of their
businesses, the Owned Property and/or any Leased Property, except for those
which alone or in the aggregate would not reasonably be expected to have a
Material Adverse Effect.

(y)    UCC Terminations. As soon as reasonably practicable after the Closing,
the applicable Borrower shall use reasonable commercial efforts to obtain or
file UCC-3 terminations with respect to such liens as are listed on the attached

payments to that Borrower or the applicable subsidiary with respect to the

(30) days after AETI’s receipt of the above written notice. If any part of the

equal to $52,500.00; provided, however, that such amount shall be payable no
more than once at any time while the Obligations remain outstanding. The
obligation in this paragraph shall survive the termination of this Agreement and
the payment of the Note and shall be in addition to any other fees that may be
payable upon a repayment or amendment of the Note.

this Agreement to the contrary notwithstanding, until the Obligations have been
paid in full, the following shall apply:

(i)    Investments in BOMAY and MIEFE shall be permitted only if approved in
advance in writing by the Lender.

(ii)     Annual funding of up to $100,000.00 to M&I Brazil shall be permitted,
so long as no Event of Default under the Note is continuing or would result
therefrom (with the amount of any such funding to count against the Annual CapEx
Limit). In addition, up to $500,000.00 of additional debt by M&I Brazil shall be
permitted if (i) such debt is non-recourse as to BOMAY, MIEFE, any Borrower, and
any subsidiary of any Borrower (other than M&I Brazil) and (ii) such debt is at
all times fully backed by an irrevocable letter of credit from a bank reasonably
acceptable to the Lender. Any agreements with respect to the foregoing shall be
in a form reasonably acceptable to the Lender. No other Investments in M&I
Brazil shall be permitted unless approved in writing in advance by the Lender.

convenience of reference and shall not form a part of, or affect the

representation, warranty, covenant or undertaking with respect to such subject
matter. No provision of this Agreement shall be waived or amended other than by
an instrument in writing signed by the Borrowers and the Lender. No delay or
omission of a party hereto in exercising any right or remedy hereunder shall

the benefit of the parties hereto and their respective successors and permitted
assigns; provided, however, that (i) no Borrower shall assign this Agreement or
any of its rights or obligations hereunder without the Lender’s prior written
consent and (ii) the Lender may assign any or all of its rights and obligations
hereunder to any individual or entity to whom the Lender assigns or transfers

notice and such transferee agrees in writing to be bound, with respect to the

anything herein to the contrary, upon at least thirty (30) days prior written
notice to the Borrowers the Lender may pledge all or any part of the Note as
collateral for a bona fide loan pursuant to a security agreement with a third
party lender which is an

violation of this Agreement so long as it is made in compliance with all
applicable laws, it being acknowledged that such third party lender shall be

provided in the Closing Documents. In the event that the Lender (i) sells,
assigns or transfers the Note in accordance with the provisions hereof or
(ii) pledges all or any part of the Note as collateral for a bona fide loan, in

and the Lender contained herein shall survive the Closing.

statements with respect to the transactions contemplated hereby, including a
“tombstone” describing the financing provided pursuant to this Agreement.

(k)    Further Assurance. Each party shall do and perform, or cause to be done
and performed, at its expense (subject to Section 4(b) above), all such further
acts and things, and shall execute and deliver all such other agreements,
certificates, instruments and documents, as another party may reasonably request
in order to carry out the intent and accomplish the purposes of this Agreement
and the consummation of the transactions contemplated hereby.

(l)    Remedies. No provision of this Agreement providing for any specific
remedy to a party shall be construed to limit such party to that specific
remedy, and any other remedy that would otherwise be available to such party at
law or in equity shall also be available. The parties also intend that the
rights and remedies hereunder be cumulative, so that exercise of any one or more
of such rights or remedies shall not preclude the later or concurrent exercise
of any other rights or remedies.

(m)    Acknowledgment Regarding the Lender’s Purchase. Each Borrower
acknowledges that the Lender is not acting as a financial advisor to, or
fiduciary of, any of the Borrowers (or in any similar capacity) with respect to
this Agreement or any of the transactions contemplated hereby. This Agreement
and the transactions contemplated hereby, and the relationship between the
Lender and the Borrowers, is and will be considered “arms-length”
notwithstanding any other or prior agreement or nexus between the Lender and any
Borrower, whether or not disclosed. Other than the representations and
warranties set forth in Section 2 hereof, any statements made by the Lender or
any of its representatives or agents in connection with this Agreement and the
transactions contemplated hereby are not to be construed as advice or a
recommendation, are merely incidental to the Lender’s purchase of the Note, and
have not been relied upon in any way by any Borrower or its management. Each
Borrower’s decision to enter into this Agreement and the transactions
contemplated hereby has been based solely upon an independent evaluation by that
Borrower and its management.

relief against another party arising out of or in connection with this
Agreement, in addition to all other remedies to which the prevailing party may
be entitled, the losing party shall be required to pay to the prevailing party a
reasonable sum for attorney’s fees and costs incurred in bringing or defending
such action and/or enforcing any judgment granted therein, all of which shall be
deemed to have accrued upon the commencement of such action. Any judgment or
order entered in such action shall contain a specific provision providing for

For the purposes of this paragraph, attorney’s fees shall include, without
limitation, fees incurred with respect to the following: (i) post-judgment
motions, (ii) contempt proceedings, (iii) garnishment, levy and debtor and third
party examinations, (iv) discovery, (v) bankruptcy litigation and (vi) any
