                               REPAYMENT GUARANTY

        THIS REPAYMENT GUARANTY (as the same may from time to time hereafter be
modified, supplemented or amended, the "GUARANTY") is made as of October 4,
2004, by BEHRINGER HARVARD SHORT-TERM OPPORTUNITY FUND I LP, having an address

Commercial Operations Center, 555 Dividend Drive, Suite 150, Mailstop 3545PMTX,
Coppell, Texas 75019, Attn: Portfolio Administration ("LENDER").

                                    RECITALS:

A.      Lender has agreed to make a loan (the "LOAN") in the original principal
sum of SIX MILLION and No/100 Dollars (U.S. $6,000,000.00) to Behringer Harvard
1221 Coit LP, a Texas limited partnership ("BORROWER"); and

B.      The Loan is evidenced by Borrower's secured promissory note of even date
herewith made payable and delivered to Lender (as the same may from time to time
hereafter be modified, amended, supplemented, extended or consolidated, and any
note(s) issued in exchange therefore or replacement thereof, the "NOTE") and
further evidenced and secured by a mortgage executed by Borrower of even date
herewith (it being agreed that "MORTGAGE" as hereinafter used shall be construed
to mean "mortgage" or "deed of trust" or "trust deed" or "deed to secure debt"
as the context so requires, as the same may from time to time hereafter be
modified, amended, supplemented or extended) on the Premises more particularly
described in said Mortgage; and

C.      In connection with the Loan, the Borrower has also entered into that
certain Loan Agreement of even date herewith by and between Lender and Borrower
(as the same may from time to time hereafter be modified, amended, supplemented
or extended, the "LOAN AGREEMENT"); and

D.      It is a condition of Lender's agreement to make the Loan that Guarantor
be unconditionally liable for and personally guarantee the payment and
performance of the Indebtedness represented by the Note and the performance of
any and all other liabilities and obligations of the Borrower under the Loan
Documents upon the terms and conditions as are hereinafter set forth; and

E.      Guarantor is financially interested in Borrower and is materially
benefited by the consummation of the Loan and has agreed to unconditionally and
personally guarantee the payment and performance of the Indebtedness represented
by the Note and the performance of any and all other liabilities and obligations
of Borrower under the Loan Documents upon the terms and conditions as are
hereinafter set forth.

        NOW, THEREFORE, in order to induce Lender to make the Loan to Borrower,
Guarantor, intending to be legally bound, hereby makes the following
representations and warranties to Lender and hereby covenants and agrees with
Lender as follows:

1.      FULL GUARANTY. Guarantor hereby unconditionally, absolutely and
irrevocably guarantees and promises to pay to Lender or order, on demand, in
lawful money of the United States of America, in immediately available funds,
the Loan when due, whether by acceleration or otherwise, together with all
interest thereon, any other sums that become due and owing to Lender under the
Loan Documents, including, without limitation, late charges, premiums for
prepayment, expenditures by Lender to preserve and protect the collateral for
repayment of the Note, amounts that would become due but for the effect of any
bankruptcy proceedings or other insolvency proceedings and all attorneys' fees,
costs, and expenses of collection incurred by Lender in enforcing its rights and

                                       1
<PAGE>

remedies under the Loan Documents, and together with the full and complete
discharge and performance of each and every other term, covenant, obligation,
and warranty contained in the Loan Documents.

2.      REMEDIES. If Guarantor fails to promptly perform its obligations under
this Guaranty, Lender may from time to time, and without first requiring
performance by Borrower or exhausting any or all security for the Loan, bring
any action at law or in equity or both to compel Guarantor to perform its
obligations hereunder, and to collect in any such action compensation for all
loss, cost, damage, injury and expense sustained or incurred by Lender as a
direct or indirect consequence of the failure of Guarantor to perform its
obligations, together with interest thereon at the rate of interest applicable
to the principal balance of the Note. Any amounts due under this SECTION 2 shall
be in addition to the amounts due under SECTION 1 of this Guaranty.
Notwithstanding anything contained herein to the contrary, any liability of
Guarantor under this Guaranty shall be satisfied solely out of the properties
and assets of Guarantor that may exist from time to time and Lender specifically
agrees that there shall be no recourse under this Guaranty to the general or
limited partners of Guarantor, or their respective properties and assets, for
the satisfaction of any liability of Guarantor hereunder.

3.      RIGHTS OF LENDER. Guarantor authorizes Lender, without giving notice to
Guarantor or obtaining Guarantor's consent and without affecting the liability
of Guarantor, from time to time to: (a) renew or extend all or any portion of
Borrower's obligations under the Note, the Loan Agreement or any of the other
Loan Documents; (b) declare all sums owing to Lender under the Note, the Loan
Agreement and the other Loan Documents due and payable upon the occurrence of an
Event of Default under the Loan Documents; (c) make changes in the dates
specified for payments of any sums payable in periodic installments under the
Note, the Loan Agreement or any of the other Loan Documents; (d) otherwise
modify, amend, supplement or replace from time to time the terms of any of the
Loan Documents; (e) take and hold security for the performance of Borrower's
obligations under the Note, the Loan Agreement or the other Loan Documents and
exchange, enforce, waive and release any such security; (f) apply such security
and direct the order or manner of sale thereof as Lender in its sole discretion
may determine; (g) release, substitute or add any one or more endorsers of the
Note or guarantors of Borrower's obligations under the Note, the Loan Agreement
or the other Loan Documents; (h) apply payments received by Lender from Borrower
to any obligations of Borrower to Lender, in such order as Lender shall
determine in its sole discretion, whether or not any such obligations are
covered by this Guaranty; and (i) assign this Guaranty in whole or in part.

4.      WAIVERS. Guarantor waives: (a) any defense based upon any legal
disability or other defense of Borrower, any other guarantor or other Person, or
by reason of the cessation or limitation of the liability of Borrower from any
cause other than full payment of all sums payable under the Note, the Loan
Agreement or any of the other Loan Documents; (b) any defense based upon any
lack of authority of the officers, directors, partners, members, managers or
agents acting or purporting to act on behalf of Borrower or any principal of
Borrower or any defect in the formation of Borrower or any principal of
Borrower; (c) any defense based upon the application by Borrower of the proceeds
of the Loan for purposes other than the purposes represented by Borrower to
Lender or intended or understood by Lender or Guarantor; (d) all rights and
defenses arising out of an election of remedies by Lender, even though that
election of remedies, such as a nonjudicial foreclosure with respect to security
for a guaranteed obligation, has destroyed Guarantor's rights of subrogation and
reimbursement against Borrower; (e) any defense based upon Lender's failure to
disclose to Guarantor any information concerning Borrower's financial condition
or any other circumstances bearing on Borrower's ability to pay all sums payable
under the Note, the Loan Agreement or any of the other Loan Documents; (f) any
defense based upon any statute or rule of law which provides that the obligation
of a surety must be neither larger in amount nor in any other respects more
burdensome than that of a principal; (g) any defense based upon Lender's
election, in any proceeding instituted under the Bankruptcy Code, of the
application of Section 1111(b)(2) of the Bankruptcy Code or any successor
statute; (h) any defense based upon any borrowing or any grant of a security
interest under Section 364 of the Bankruptcy Code; (i) presentment, demand,
protest and notice of any kind; and (j) the benefit of any statute of
limitations affecting the liability of Guarantor hereunder or the enforcement
hereof. In addition, Guarantor waives all rights and defenses that Guarantor may
have because Borrower's debt is secured by real property, including, without
limitation, those contained in Sections 51.004 and 51.005 of the Texas Property
Code. This means, among other things: (A) Lender may collect from Guarantor
without first foreclosing on any real or personal property collateral pledged by
Borrower; and (B) if Lender forecloses on any real property collateral pledged
by Borrower, then (i) the amount of the debt may be reduced only by the price
for which that collateral is sold at the foreclosure sale, even if the
collateral is worth more than the sale price; and (ii) Lender may collect from
Guarantor even if Lender, by foreclosing on the real property collateral, has
destroyed any right Guarantor may have to collect from Borrower.

                                        2
<PAGE>

The foregoing sentence is an unconditional and irrevocable waiver of any rights
and defenses Guarantor may have because Borrower's debt is secured by real
property. Finally, Guarantor agrees that the payment of all sums payable under
the Note, the Loan Agreement or any of the other Loan Documents or any part
thereof or other act which tolls any statute of limitations applicable to the
Note, the Loan Agreement or the other Loan Documents shall similarly operate to
toll the statute of limitations applicable to Guarantor's liability hereunder.

5.      REPRESENTATIONS, WARRANTIES AND COVENANTS. Guarantor represents,
warrants and acknowledges that: (a) Lender would not make the Loan but for this
Guaranty; (b) there are no conditions precedent to the effectiveness of this
Guaranty; (c) Guarantor has established adequate means of obtaining from sources
other than Lender, on a continuing basis, financial and other information

to Guarantor as to any such matters; (d) the most recent financial statements of
Guarantor previously delivered to Lender are true and correct in all respects,

Lender; (g) Guarantor and Borrower are separate and distinct entities with no
identity of interest with respect to any Indebtedness which may become owed or

instrument of Guarantor, or any indenture, agreement or other instrument to
which Guarantor is a party or by which Guarantor or any of Guarantor's assets is
or may be bound or affected; (v) does not and will not result in the creation or
imposition of any lien, charge or encumbrance whatsoever upon any of Guarantor's

information, including, without limitation, annual financial

                                       5
<PAGE>

statements, cash flow projections and quarterly operating statements, requested
by Lender. Additionally, Guarantor shall delivery to Lender, as soon as
available, but in no event later than sixty (60) days after each Quarterly
Financial Covenant Test Date, a current, unaudited financial statement
(including, without limitation, an income and expense statement, balance sheet
and cash flow statement) signed by Guarantor's Chief Financial Officer. Within
sixty (60) days of Lender's request, Guarantor shall also deliver to Lender such
other financial information as Lender may specify. Except as set forth herein or
otherwise agreed to by Lender, all such financial information shall be prepared
on a GAAP Basis consistently applied.

        (e)     QUARTERLY FINANCIAL COVENANT COMPLIANCE CERTIFICATES. On or
before sixty (60) days following each Quarterly Financial Covenant Test Date,
Guarantor shall deliver to Lender a Financial Covenant Compliance Certificate in
form attached hereto as EXHIBIT A ("QUARTERLY COMPLIANCE CERTIFICATE"),
certified by an officer of Guarantor, and an unqualified, unaudited financial
statement of Guarantor covering the preceding twelve (12) month period. Upon
request of Lender, Borrower shall provide any and all financial information and
statements and other documents or items to support or evidence the
certifications contained in each Quarterly Compliance Certificate.

7.      SUBORDINATION. Guarantor subordinates all present and future
indebtedness owing by Borrower to Guarantor to the Indebtedness at any time
owing by Borrower to Lender under the Note, the Loan Agreement and the other
Loan Documents; PROVIDED, HOWEVER, so long as no Event of Default has occurred
and is continuing, Guarantor shall be entitled to receive partnership
distributions from Borrower to the extent attributable solely to Guarantor's
limited partnership interest in Borrower. Guarantor agrees that as long as this
Guaranty is in effect, Guarantor will not take any action or initiate any
proceedings, judicial or otherwise, to enforce Guarantor's rights or remedies
with respect to any such indebtedness, including, without limitation, any action
to enforce remedies with respect to any defaults under such indebtedness or to
any collateral securing such indebtedness or to obtain any judgment or
prejudgment remedy against Borrower or any such collateral. Guarantor also
agrees that it shall not commence or join with any other creditor or creditors
of Borrower in commencing any bankruptcy, reorganization or insolvency
proceedings against Borrower. Guarantor further agrees not to assign all or any
part of such indebtedness unless Lender is given prior notice and such
assignment is expressly made subject to the terms of this Guaranty. If Lender so
requests, (a) all instruments evidencing such indebtedness shall be duly
endorsed and delivered to Lender, (b) all security for such indebtedness shall
be duly assigned and delivered to Lender, (c) such indebtedness shall be
enforced, collected and held by Guarantor as trustee for Lender and shall be
paid over to Lender on account of the Loan, but without reducing or affecting in
any manner the liability of Guarantor under the other provisions of this
Guaranty; and (d) Guarantor shall execute, file and record such documents and
instruments and take such other action as Lender deems necessary or appropriate
to perfect, preserve and enforce Lender's rights in and to such indebtedness and
any security therefor. If Guarantor fails to take any such action, Lender, as
attorney-in-fact for Guarantor, is hereby authorized to do so in the name of
Guarantor. The foregoing power of attorney is coupled with an interest and
cannot be revoked.

8.      BANKRUPTCY OF BORROWER. In any bankruptcy or other proceeding in which
the filing of claims is required by law, Guarantor shall file all claims which
Guarantor may have against Borrower relating to any indebtedness of Borrower to
Guarantor and shall assign to Lender all rights of Guarantor thereunder. If
Guarantor does not file any such claim, Lender, as attorney-in-fact for
Guarantor, is hereby authorized to do so in the name of Guarantor or, in
Lender's discretion, to assign the claim to a nominee and to cause proof of
claim to be filed in the name of Lender's nominee. The foregoing power of
attorney is coupled with an interest and cannot be revoked. Lender or its
nominee shall have the right, in its reasonable discretion, to accept or reject
any plan proposed in such proceeding and to take any other action which a party
filing a claim is entitled to do. In all such cases, whether in administration,
bankruptcy or otherwise, the Person or Persons authorized to pay such claim
shall pay to Lender the amount payable on such claim and, to the full extent
necessary for that purpose, Guarantor hereby assigns to Lender all of
Guarantor's rights to any such payments or distributions; PROVIDED, HOWEVER,
Guarantor's obligations hereunder shall not be satisfied except to the extent
that Lender receives cash by reason of any such payment or distribution. If
Lender receives anything hereunder other than cash, the same shall be held as
collateral for amounts due under this Guaranty. If all or any portion of the
obligations guarantied hereunder are paid or performed, the obligations of
Guarantor hereunder shall continue and shall remain in full force and effect in
the event that all or any part of such payment or performance is avoided or
recovered directly or indirectly from Lender as a preference, fraudulent
transfer or otherwise under the Bankruptcy Code or other similar laws,
irrespective of: (a) any notice of

                                       6
<PAGE>

revocation given by Guarantor prior to such avoidance or recovery; and (b) full
payment and performance of all of the Indebtedness and obligations evidenced and
secured by the Loan Documents.

9.      DISCLOSURE OF INFORMATION; PARTICIPATIONS. Guarantor agrees that Lender
may elect, at any time, to sell, assign, participate or securitize all or any
portion of Lender's rights and obligations under the Loan Documents (any of the
foregoing, a "SECURITIZATION TRANSACTION"). Guarantor agrees that Lender may
disseminate any and all information pertaining to the Premises, Borrower, any
Interest Owner, Guarantor or any other guarantor to any relevant party in
connection with such Securitization Transaction.

10.     ADDITIONAL AND INDEPENDENT OBLIGATIONS. This is a guaranty of payment
and not of collection and the obligations of Guarantor hereunder shall be in
addition to and shall not limit or in any way affect the obligations of
Guarantor under any other existing or future guaranties unless said other
guaranties are expressly modified or revoked in writing. This Guaranty is
independent of the obligations of Borrower under the Note, the Loan Agreement,
the Mortgage and the other Loan Documents. Guarantor agrees that nothing
contained in this Guaranty shall prevent Lender from suing to collect on the
Note or from exercising concurrently or successively any rights available to it
at law and/or in equity or under any of the Loan Documents, and that the
exercise of any of the aforesaid rights shall not constitute a legal or
equitable discharge of Guarantor. Guarantor hereby authorizes and empowers
Lender to exercise, in its sole discretion, any rights and remedies, or any
combination thereof, which may then be available, since it is the intent and
purpose of Guarantor that the obligations hereunder shall be absolute,
independent and unconditional under any and all circumstances. Lender may bring
a separate action to enforce the provisions hereof against Guarantor without
taking action against Borrower or any other Person or joining Borrower or any
other Person as a party to such action.

11.     MISCELLANEOUS.

        11.1    GUARANTY NOT SECURED BY LOAN DOCUMENTS. Notwithstanding anything
contained herein or in the other Loan Documents to the contrary, this Guaranty
and all obligations of Guarantor arising under it shall not be secured in any
manner whatsoever, including by the Mortgage or by any lien encumbering the
Premises.

        11.2    ATTORNEYS' FEES; ENFORCEMENT. If any attorney is engaged by
Lender to enforce or defend any provision of this Guaranty, or any of the other
Loan Documents, or as a consequence of any Event of Default under the Loan
Documents, with or without the filing of any legal action or proceeding
(including any bankruptcy proceeding), Guarantor shall pay to Lender immediately
upon demand all reasonable attorneys' fees and costs incurred by Lender in
connection therewith, together with interest thereon from the date of such
demand until paid at the rate of interest applicable to the principal balance of
the Note as specified therein. Any amounts due under this SECTION 11.2 shall be
in addition to the amounts due under SECTION 1 of this Guaranty.

        11.3    RULES OF CONSTRUCTION; DEFINED TERMS. The word "Borrower" as
used herein shall include both the named Borrower and any other Person at any
time assuming or otherwise becoming primarily liable for all or any part of the
obligations of the named Borrower under the Note, the Loan Agreement and the
other Loan Documents. If this Guaranty is executed by more than one Person, the
term "Guarantor" shall include all such Persons. When the context and
construction so require, all words used in the singular herein shall be deemed
to have been used in the plural and vice versa. All headings appearing in this
Guaranty are for convenience only and shall be disregarded in construing this
Guaranty. Capitalized terms not otherwise defined herein shall have the meanings
set forth in the Loan Agreement or the other Loan Documents, as applicable.

        11.4    CREDIT REPORTS. Each Person obligated on this Guaranty hereby
authorizes Lender to order and obtain, from a credit reporting agency of
Lender's choice, a third party credit report on such Person.

        11.5    GOVERNING LAW. This Guaranty shall be governed by, and construed
in accordance with, the laws of the State where the Premises are located,
without regard to its conflict of law principles.

        11.6    CONSENT TO JURISDICTION. Guarantor irrevocably submits to the
jurisdiction of any state or federal court sitting in the State of Washington,
the State where the Premises are located, and the State in which Guarantor's
principal place of business is located over any suit, action, or proceeding
arising out of or relating to this Guaranty,

                                       7
<PAGE>

the Loan Documents or the Loan evidenced thereby and any state court sitting in
the county of the State where the Premises are located over any suit, action, or
proceeding brought by Lender to exercise any of its rights under this Guaranty
or the Loan Documents. Guarantor irrevocably waives, to the fullest extent
permitted by law, any objection that Guarantor may now or hereafter have to the
laying of venue of any such suit, action or proceeding brought in any such court
and any claim that any such suit, action or proceeding brought in any such court
has been brought in an inconvenient forum. Guarantor further consents and agrees
to service of any summons, complaint or other legal process in any such suit,
action or proceeding by registered or certified U.S. mail, postage prepaid, to
Guarantor at the address for notices described on page 1 of this Guaranty, and
consents and agrees that such service shall constitute in every respect valid
and effective service (but nothing herein shall affect the validity or
effectiveness of process served in any other manner permitted by law).

        11.7    HEIRS, SUCCESSORS AND ASSIGNS. The provisions of this Guaranty
will bind and benefit the heirs, executors, administrators, legal
representatives, nominees, successors and assigns of Guarantor and Lender.

        11.8    JOINT AND SEVERAL LIABILITY. The liability of all Persons who
are in any manner obligated hereunder shall be joint and several.

        11.9    SEVERABILITY. If any provision of this Guaranty shall be
determined by a court of competent jurisdiction to be invalid, illegal or
unenforceable, that portion shall be deemed severed from this Guaranty and the
remaining parts shall remain in full force as though the invalid, illegal or
unenforceable portion had never been part of this Guaranty.

        11.10   SURVIVAL. This Guaranty shall be deemed to be continuing in
nature and shall remain in full force and effect and shall survive the exercise
of any remedy by Lender under the Mortgage or any of the other Loan Documents,
including, without limitation, any foreclosure or deed in lieu thereof.

        11.11   ENFORCEABILITY. Guarantor hereby acknowledges that: (a) the
obligations undertaken by Guarantor in this Guaranty are complex in nature; and
(b) numerous possible defenses to the enforceability of these obligations may
presently exist and/or may arise hereafter; and (c) as part of Lender's
consideration for entering into the Loan, Lender has specifically bargained for
the waiver and relinquishment by Guarantor of all such defenses; and (d)
Guarantor has had the opportunity to seek and receive legal advice from skilled
legal counsel in the area of financial transactions of the type contemplated
herein. Given all of the above, Guarantor does hereby represent and confirm to
Lender that Guarantor is fully informed regarding, and that Guarantor does
thoroughly understand: (i) the nature of such possible defenses; and (ii) the
circumstances under which such defenses may arise; and (iii) the benefits which
such defenses might confer upon Guarantor; and (iv) the legal consequences to
Guarantor of waiving such defenses. Guarantor acknowledges that Guarantor makes
this Guaranty with the intent that this Guaranty and all of the informed waivers
herein shall each and all be fully enforceable by Lender, and that Lender is
induced to enter into the Loan in material reliance upon the presumed full
enforceability thereof.

        11.12   COUNTERPARTS. This Guaranty may be executed in counterparts,
each of which shall be deemed an original, and such counterparts when taken
together shall constitute but one agreement.

        11.13   NOTICES. Any and all notices given in connection with this
Guaranty shall be deemed adequately given only if in writing and addressed to

 (b) Each Notice of Borrowing shall be irrevocable and binding on the Borrowers. The Borrowers shall indemnify each Lender against any loss, cost or expense incurred by such Lender as a result of any failure to fulfill on or before the date

by it shall not relieve any other Lender of its obligation, if any, hereunder to make its Advance on the date of the Borrowing, but no Lender shall be responsible for the failure of any other Lender to make the Advance to be made by such other

such a change would avoid the need for, or reduce the amount of, any such increased costs and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender. 
  
 (d) If any Lender requests compensation pursuant to Section 2.08 or 2.10 of
this Agreement, or the obligation of any Lender to make or maintain Advances bearing interest at the Eurodollar Rate shall be suspended pursuant to Section 2.09 (such Lender being an “Affected Lender”), then, so
long as such condition exists, the Borrowers may, so long as no Default has 

  

 22 

 
occurred and is continuing, on any date occurring at least 15 days after the date of such request or suspension, (a) designate an Eligible Assignee approved
by the Administrative Agent (which approval shall not be unreasonably withheld or delayed) (such Eligible Assignee being a “Replacement Lender”) to assume the Affected Lender’s Advances and other rights and
obligations under this Agreement and the Notes (all without recourse to or representation or warranty by, or expense to, the Affected Lender) for a purchase price equal to the principal amount of the outstanding Advances held by the Affected Lender
plus all accrued and unpaid interest thereon plus all fees and other amounts owing to the Affected Lender under this Agreement and the Notes at such time, and, subject to the execution and delivery to the Administrative Agent by the
Replacement Lender of documentation satisfactory to the Administrative Agent and compliance with the requirements of Section 11.07, the Replacement Lender shall succeed to the rights and obligations of the Affected Lender under this Agreement and
the Notes, (b) pay, or cause to be paid, to the Affected Lender all amounts payable to such Affected Lender under Section 11.04(c), calculated as if the purchase by the Replacement Lender constituted a mandatory prepayment of Advances by the
Borrowers, and (c) pay to the Administrative Agent the processing and recordation fee specified in Section 11.07(a) with respect to such assignment; provided, however, that in the event the amount of Advances to be assumed by
Replacement Lenders is less than the total amount of outstanding Advances held by all Affected Lenders, each Affected Lender’s outstanding Advances shall be reduced on a pro rata basis or in such other proportion as the Borrowers and all
Affected Lenders may agree. If the Borrowers exercise their rights under the immediately preceding sentence, the Affected Lender shall no longer be a party to this Agreement or have any rights or obligations under this Agreement or the Notes;
provided that (i) the obligations of the Borrowers to the Affected Lender under Sections 2.08, 2.10 and 11.04 and (ii) the obligations of such Affected Lender under Section 9.05 to the Administrative Agent, in each case with respect to events
or circumstances occurring or obligations arising prior to, or as a result of, any such replacement shall survive such exercise by the Borrowers. 
  
 (e) Notwithstanding any other provision of this Agreement, if any Lender shall notify the Administrative Agent that the introduction of or any change in
or in the interpretation of any law or regulation makes it unlawful, or any central bank or other governmental authority asserts that it is unlawful, for any Lender or its Lending Office to perform its obligations hereunder to make Advances or to
fund or maintain Advances hereunder which, in each case, shall accrue interest at the Eurodollar Rate pursuant to Section 2.06(a)(i) of this Agreement, each such Advance will automatically, upon such demand, convert into a Base Rate Advance and the
Administrative Agent shall promptly notify the Collateral Agent of such conversion. 
  
 SECTION 2.09 Payments and Computations. (a) The Borrowers and, in the case of payments made from the Collateral Account on behalf of the Borrowers pursuant to Section 8.04 of this Agreement, the
Collateral Agent, shall make each payment hereunder and under the Notes, irrespective, in the case of the Borrowers, of any right of counterclaim or set-off, not later than 11:00 A.M. (New York City time) on the day when due in U.S. Dollars to the
Administrative Agent at the Administrative Agent’s Account in same day funds, with payments being received by the Administrative Agent after such time being deemed to have been received on the next succeeding Business Day. The Administrative
Agent will promptly thereafter cause like funds to be distributed (i) if such payment by the Borrowers is in respect of principal, interest, any fees or any other Obligation then payable hereunder and under the Notes to more 

  

 23 

 
than one Lender, to such Lender for the account of their respective Lending Offices ratably in accordance with the amounts of such respective Obligations
then payable to such Lender and (ii) if such payment by the Borrowers is in respect of any Obligation then payable hereunder to one Lender, to such Lender for the account of its Lending Office, in each case to be applied in accordance with the terms
of this Agreement. Upon its acceptance of an Assignment and Acceptance and recording of the information contained therein in the Register pursuant to Section 11.07, from and after the effective date of such Assignment and Acceptance, the
Administrative Agent shall make all payments hereunder and under the Notes in respect of the interest assigned thereby to the Lender assignee thereunder, and the parties to such Assignment and Acceptance shall make all appropriate adjustments in
such payments for periods prior to such effective date directly between themselves. 
  
 (b) The Borrowers hereby authorize each Lender, and each of its Affiliates, if and to the extent payment owed to such Lender is not made when due hereunder or under the Note held by such Lender, to charge from time to
time against any or all of the Borrowers’ accounts with such Lender any amount so due. 
  
 (c) All computations of interest shall be made by the Administrative Agent on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring
in the period for which such interest, fees or commissions are payable. Each determination by the Administrative Agent of an interest rate, fee or commission hereunder shall be conclusive and binding for all purposes, absent manifest error. The
Administrative Agent shall promptly (but in no case later than the Business Day before each Payment Date) forward to the Collateral Agent notice of the Actual Debt Service Amount payable on such Payment Date. The Administrative Agent shall also
notify the Collateral Agent from time to time of any amount of (i) Administrative Agent Expense with respect to the Administrative Agent and (ii) Lender Expense Amount payable under section 8.04 hereof. In addition, upon the occurrence of a Cash
Collection Event the Administrative Agent shall promptly (but in no event later than the Business Day before the relevant Payment Date) notify the Collateral Agent of the Actual Debt Service Amount for the Interest Period commencing on such Payment
Date and the Anticipated Debt Service Amount for the next succeeding Interest Period. 
  
 (d) Unless the Administrative Agent shall have received notice from the Borrowers prior to the date on which any payment is due to any Lender hereunder that the Borrowers will not make such payment in full, the
Administrative Agent may assume that the Borrowers have made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each such Lender on such due
date an amount equal to the amount then due such Lender. If and to the extent the Borrowers shall not have so made such payment in full to the Administrative Agent, each such Lender shall repay to the Administrative Agent forthwith on demand such
amount distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent, at the Federal Funds Rate. 

 
 SECTION 2.10 Taxes. (a) Any and all payments by or for the
account of any Borrower hereunder or under the Notes shall be made free and clear of, and without deduction of 

  

 24 

 
or withholding for, or on account of, any present or future taxes, duties, levies, imposts, assessments, deductions, withholdings or governmental charges of
whatever nature and all liabilities with respect thereto imposed, levied, collected, withheld or assessed by any Taxing Authority (including, without limitation, by such Taxing Authority or any political subdivision thereof), excluding (i) in
the case of each Lender and each Agent, taxes imposed on its overall net income, and franchise taxes imposed on it in lieu of a tax on overall net income, by the jurisdiction under the laws of which such Lender or Agent (as the case may be) is
organized or any political subdivision thereof or (ii) in the case of each Lender, taxes imposed on its overall net income and franchise taxes imposed on it in lieu of a tax on overall net income, by the jurisdiction of such Lender’s Lending
Office (all such non-excluded taxes, duties, assessments, levies, imposts, deductions, withholding, governmental charges and liabilities with respect to thereto being hereinafter referred to as “Taxes”). If any
Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under any Note to any Lender or the Administrative Agent, (i) the sum payable by such Borrower shall be increased as may be necessary so that
after such Borrower has made all required deductions or withholdings of Taxes (including deductions applicable to additional sums payable under this Section 2.10) such Lender or Administrative Agent (as the case may be) receives an amount equal to
the sum it would have received had no such deductions or withholdings been made, (ii) such Borrower shall make such deductions or withholdings and (iii) such Borrower shall pay the full amount deducted or withheld to the relevant Taxing Authority or
other authority in accordance with applicable law. 
  
 (b) Each
Borrower shall pay any present or future stamp, issue, registration or documentary taxes or any other excise or property taxes and other duties (including interest and penalties with respect thereto) which arise from any payment made hereunder or
under the Notes or from the execution, delivery or registration of, or otherwise with respect to, this Agreement or the Notes, excluding those taxes, charges and levies imposed by any jurisdiction outside Mexico or the United States except
such non-Mexican or non-United States taxes, charges and levies resulting from enforcement of this Agreement following an Event of Default (hereinafter referred to as “Other Taxes”). 
  
 (c) Each Borrower shall provide the Administrative Agent with a duly
certified or authenticated copy of an original receipt of payment, and other documentation satisfactory to the Administrative Agent, evidencing the payment of Taxes within 30 days following such payment or if later, within five Business Days after
receipt of such documentation. Copies of such documentation will be made available to the Lenders, upon request therefor. If no Taxes are payable in respect of any payment hereunder or under the Notes, each Borrower will furnish to the
Administrative Agent, at the address listed in Section 11.02, a certificate from each appropriate Taxing Authority, or an opinion of counsel acceptable to the Administrative Agent, in either case stating that such payment is exempt from and not
subject to Taxes. 
  
 (d) Each Borrower shall indemnify each
Lender and the Administrative Agent for and hold it harmless against the full amount of Taxes and Other Taxes (including, without limitation, taxes of any kind imposed by any jurisdiction on amounts payable under this Section 2.10) imposed on or
paid by such Lender or the Administrative Agent (as the case may be) and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally
asserted. This 

  

 25 

 
indemnification shall be made within 30 days from the date such Lender or the Administrative Agent (as the case may be) makes written demand therefor. Prior
to the payment by any Lender of any Taxes or Other Taxes, such Lender will endeavor to notify each Borrower of its intention to make such payment, but the failure of any Lender so to notify shall not affect such Borrower’s reimbursement
obligation under this subsection. 
  
 (e) Without prejudice to the
survival of any other agreement of each Borrower hereunder, the agreements and obligations of each Borrower contained in this Section 2.10 shall survive the payment in full of principal and interest hereunder and under the Notes. 
  
 SECTION 2.11 Sharing of Payments, Etc. (a) If any Lender shall obtain
any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of any Advance owing to it (other than pursuant to Section 2.08, 2.10 or 11.04(c) of this Agreement) in excess of its ratable share
of payments on account of the Advances obtained by all the Lenders, such Lender shall forthwith purchase from the other Lenders such participations in the Advances owing to them as shall be necessary to cause such purchasing Lender to share the
excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall
repay to the purchasing Lender the purchase price to the extent of such recovery together with an amount equal to such Lender’s ratable share (according to the proportion of (i) the amount of such Lender’s required repayment to (ii) the
total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. Each Borrower agrees that any Lender so purchasing a participation from
another Lender pursuant to this Section 2.11 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of
such Borrower in the amount of such participation. 
  
 (b) If at
any time there shall occur and be continuing a Monetary Control Condition, then one or more Lenders (each, an “Accepting Lender”) may agree to receive payment of principal of and all accrued and unpaid interest
on its Advance in Mexican Pesos (each Advance so paid, an “Affected Advance”), and such Accepting Lender (and each Lender becoming an Additional Accepting Lender as referred to below) shall not be required to
purchase a participation from, or make such other adjustments with, any other Lender in respect of the other Advance. Prior to accepting any such payment as described above with respect to any prospective Affected Advance, each Accepting Lender
shall provide reasonable notice to the Agents (who shall promptly notify each other Lender) of such proposed payment in Mexican Pesos, setting forth the proposed terms thereof, and each other Lender that elects, by notice delivered promptly to each
Borrower and the Agents to receive the same such payment in Pesos with respect to its Advance (an “Additional Accepting Lender”) shall receive a payment with respect thereto pro rata to that received by
the initial Accepting Lender. Any such agreement to make payment in Mexican Pesos pursuant to this clause (b), including the calculation of the exchange rate with respect to U.S. Dollars, shall be binding on any Lender agreeing to such payment and
shall constitute full and final payment with respect to the amounts of the Advance or Advances so paid. Nothing in this clause (b) shall be construed as a waiver by any Lender, including any Lender not accepting payment in Mexican Pesos of the
obligations of any Borrower to make payment in U.S. Dollars in accordance with Section 2.09 and Section 11.04 of 

  

 26 

 
this Agreement or any other remedies under the same. As used herein, a “Monetary Control Condition” shall exist at any
time if at such time (i) Mexico has imposed monetary or exchange controls, the effect of which is to prevent or materially delay payment by any Borrower of principal of and/or interest on any Advance in U.S. dollars, but not to prevent such payment
in Mexican Pesos, and (ii) an Event of Default under any other clause of Section 6.01 or a mandatory prepayment under Section 2.05(b) has occurred and is continuing at such time and where, in the case of an Event of Default, an acceleration of all
amounts due under this Agreement and the Notes has occurred or, in the case of a mandatory prepayment under Section 2.05(b) of this Agreement, such prepayment has not been waived. 
  
 SECTION 2.12 Use of Proceeds. The proceeds of the Advances shall be available solely to refinance outstanding
Debt of the Borrowers, to pay transaction fees and expenses and for general corporate purposes. 
  
 SECTION 2.13 Notes. Each Lender’s Advances shall be evidenced by a Note payable to the order of such Lender in an aggregate principal
amount equal to such Lender’s Commitment. In the event of any conversion of an Advance to a Base Rate Advance in accordance with Sections 2.06 or 2.08, (i) each Lender whose Advance is so converted will deliver its Note representing interest
payable at the Eurodollar Rate to the Administrative Agent and (ii) the Borrowers, at their own expense, shall execute and deliver to the Administrative Agent in exchange for each surrendered Note a new Note representing interest payable at the Base
Rate in the aggregate principal amount of such surrendered Note, dated the date of such conversion and in otherwise substantially the form of Exhibit A.

all times its properties insured against loss or damage with insurers believed by such Borrower and its Subsidiaries to be responsible, to the extent that property of a similar character is usually so insured by corporations similarly situated and
owning like properties in accordance with good business practice; provided, however, that such Borrower and its Subsidiaries may adopt such other plan or method of protection, whether by the establishment of an insurance fund or

consummate any merger or consolidation permitted under Section 5.02(c). 
  
 (f) Visitation Rights. At any reasonable time and from time to time, permit any of the Agents or any of the Lenders, or any agents or representatives thereof, to examine and make copies of and abstracts from

renewals, replacements, betterments and improvements thereof, all as in the judgment of such Borrower or such Subsidiary may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all
times; provided, however, that nothing in this Section shall prevent such Borrower and its Subsidiaries from discontinuing the operation or maintenance of any of such properties if such discontinuance is, in the judgment of such
Borrower or such Subsidiary, desirable in the conduct of its business or the business of any Subsidiary and not disadvantageous in any material respect to the Agents or the Lenders. 
  
 (i) Transactions with Affiliates. Conduct, and cause each of its Subsidiaries to conduct, all
transactions otherwise permitted under the Loan Documents with any of their 

  

 36

arm’s-length transaction with a Person not an Affiliate. 
  
 (j) Performance of Assigned Agreement. Perform and observe all the terms and provisions of the Assigned Agreement to be performed or observed by it, take such action as is necessary to maintain such Assigned

Obligations under the Loan Documents. 
  
 (n)
Receivables Generation. Refrain from taking any action or causing any Person to take any action, which action, in each case, is in the reasonable control of such Borrower and which is reasonably likely to cause the future volume of
Receivables to fall below the amount of Eligible Receivables required to avoid the occurrence of a Cash Collection Event. 
  
 (o) Obligations of Receivables Payor. Refrain from taking any action (which action is in the reasonable control of Enertec Exports)

Parties, in accordance with their terms, except as enforcement against the Receivables Payor thereunder may be limited by bankruptcy, insolvency, reorganization and other similar laws affecting the enforcement of creditors’ rights generally and
general equitable principles which may limit the right to obtain the remedy of specific performance and other equitable remedies; provided, however, that this Section 5.01(p) will neither interfere with nor prohibit Enertec
Exports’ actions relating to any good faith contractual dispute with respect to the Assigned Agreement, so 

  

 37 

 
long as such contractual disputes shall not have a material effect on the amount or collectability of Eligible Receivables or the enforceability of the
Assigned Agreement.

Enertec Exports certifying (in reasonable detail) that such amendment or waiver will not have a Material Adverse Effect and (B) a copy of such proposed amendment or waiver.

 GRANT OF SECURITY INTEREST, PLEDGE AND ASSIGNMENT 
  
 SECTION 7.01 Pledge and Assignment. Except as expressly
provided below, each Borrower hereby irrevocably pledges, transfers and assigns to the Collateral Agent for the benefit of the Lenders, and grants to the Collateral Agent, a security interest in all right, title and interest of such Borrower
(whether now owned or hereafter acquired and whether now existing or hereafter arising) in, to and under the following (the “Pledged Collateral”): 
  
 (a) Solely in respect of Enertec Exports, the Assigned Agreement, as the same may be amended or otherwise
modified from time to time (an executed copy of such Assigned Agreement is attached hereto as Annex A), including, without limitation, whether now existing or hereafter acquired or arising (i) all rights of Enertec Exports to receive monies and
other property or assets due and to become due to Enertec Exports under or pursuant to the Assigned Agreement (collectively, the “Receivables”), (ii) all claims of Enertec Exports for damages arising out of or
for breach of or default under the Assigned Agreement, (iii) all rights of Enertec Exports to receive proceeds of any 

  

 49 

 
insurance, indemnity, warranty or guaranty with respect to the Assigned Agreement, and (iv) all rights of Enertec Exports to terminate the Assigned
Agreement, to perform thereunder and to compel performance and otherwise exercise all remedies thereunder (all such Pledged Collateral listed under this Section 7.01(a) being, collectively, the “Supply Agreement
Collateral”); 
  
 (b) all
legal and beneficial rights to and interests in (i) the Collateral Account and (ii) all funds held therein and all certificates and instruments, if any, from time to time representing or evidencing such Collateral Account and (iii) all interest,
dividends, cash, instruments and other property from time to time received, receivable or otherwise distributed in respect of or in exchange for any or all funds from time to time in the Collateral Account; 
  
 (c) all legal and beneficial rights to and interests in (i)
all Eligible Investments from time to time in the Collateral Account and (ii) all certificates and instruments, if any, from time to time representing or evidencing the Eligible Investments, and (iii) all interest, earnings and proceeds in respect
thereof; and 
  
 (d) to the extent not covered by
clauses (a) through (c) above, all proceeds and products of any or all of the foregoing and, to the extent not otherwise included, all (i) payments under insurance (whether or not the Agent is the loss payee thereof), or any indemnity, warranty or
guaranty, payable by reason of loss or damage to or otherwise with respect to any of the foregoing Pledged Collateral and (ii) cash. 
  
 SECTION 7.02 Security for Obligations. The Pledged Collateral secures, in the case of each Borrower, the payment of all Obligations of such
Borrower now or hereafter existing, or incurred under, arising out of or in connection with this Agreement, whether for principal, interest, fees, expenses, indemnities or otherwise (all such Obligations being the “Secured
Obligations”). Without limiting the generality of the foregoing, the Pledged Collateral secures, in the case of each Borrower, the payment of all amounts that constitute part of the Secured Obligations and would be owed by such
Borrower to the Agent or the Lenders under this Agreement or the Notes but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, concurso mercantil, reorganization or similar proceeding involving such
Borrower. 
  
 SECTION 7.03 Delivery of Pledged
Collateral. (a) All instruments and certificates representing or evidencing the Pledged Collateral shall be delivered to and held by the Collateral Agent on behalf of the Lenders pursuant to this Agreement and shall be in suitable form
for transfer by delivery, or shall be accompanied by duly executed instruments of transfer or assignment in blank and undated, all in form and substance satisfactory to the Agents. 
  
 (b) The Collateral Agent shall have the right, at any time in its discretion after the occurrence of an Event of Default and
without notice to either Borrower, to transfer to or to register in its name any or all of such Pledged Collateral, subject to the provisions of Section 7.09. Promptly after any such transfer or registration, Collateral Agent shall give notice
thereof to each Borrower, but the failure to give such notice shall not affect any of the rights or remedies of the Collateral Agent or the Lenders hereunder. The Collateral Agent shall have the right at 

  

 50 

 
any time to exchange instruments or certificates representing or evidencing such Pledged Collateral for instruments or certificates of smaller or larger
denominations. 
  
 SECTION 7.04 Borrowers Remain
Liable. Anything herein to the contrary notwithstanding, (i) each Borrower shall remain liable under the contracts and agreements to which it is a party included in the Pledged Collateral to the extent set forth therein to perform all of
its duties and obligations thereunder to the same extent as if this Agreement had not been executed, (ii) the exercise by the Collateral Agent of any of the rights hereunder shall not release either Borrower from any of its duties or obligations
under the contracts and agreements included in the Pledged Collateral, and (iii) the Collateral Agent shall not have any obligation or liability under the contracts and agreements to which it is a party included in the Pledged Collateral by reason
of this Agreement, nor shall any such Person be obligated to perform any of the obligations or duties of either Borrower thereunder or to take any action to collect or enforce any claim for payment assigned hereunder, except as otherwise provided in
Section 7.08 hereof. 
  
 SECTION 7.05 Further
Assurances. (a) Each Borrower agrees that at any time and from time to time, at the expense of such Borrower, such Borrower will promptly execute and deliver all further instruments and documents, and take all further action that the
Collateral Agent may reasonably request, in order to perfect and protect any assignment and security interest granted or purported to be granted by it hereby or to enable the Collateral Agent to exercise and enforce its rights and remedies hereunder
with respect to any Pledged Collateral pledged by such Borrower hereunder. Without limiting the generality of the foregoing, each Borrower will upon the reasonable request of the Collateral Agent, (i) execute and deliver to the Collateral Agent such
financing or continuation statements or amendments thereto, and such other instruments or notices, as may be necessary or desirable, or as the Collateral Agent may reasonably request, in order to perfect and preserve the security interests granted
or purported to be granted by it hereby and (ii) deliver to the Collateral Agent promptly upon receipt thereof all instruments representing or evidencing any of the Pledged Collateral pledged by such Borrower hereunder duly endorsed and accompanied
by duly executed instruments of transfer or assignment, all in form and substance reasonably satisfactory to the Collateral Agent. 
  
 (b) Each Borrower hereby authorizes the Collateral Agent to file one or more financing or continuation statements, and amendments thereto, relating to all
or any part of the Pledged Collateral without the signature of such Borrower where permitted by law. A photocopy or other reproduction of this Agreement or any financing statement covering the Pledged Collateral or any part thereof shall be
sufficient as a financing statement where permitted by law. Each Borrower ratifies its authorization for the Collateral Agent to have filed such financing statements, continuation statements or amendments filed prior to the date hereof. 

 
 (c) Neither Borrower, without the prior written consent of the Collateral
Agent (after having given the Collateral Agent not less than 30 days’ prior written notice thereof and after having executed and delivered to the Collateral Agent such further instruments and documents in connection therewith as may be
requested by the Collateral Agent pursuant to this Section 7.05), shall change its name, move or transfer from the location specified in Section 11.02 hereof (or any subsequent location) its principal place of business or chief executive office, or
the location of such Borrower’s books and records with respect to the Pledged Collateral. 
  

 51 

 (d) (i) Promptly upon request by any Agent, or any Lender through the Administrative Agent, correct, and
cause each of its Subsidiaries promptly to correct, any material defect or material error that may be discovered in any Collateral Document or in the execution, acknowledgment, filing or recordation thereof, and 
  
 (ii) Promptly upon request by any Agent, or any Lender through the
Administrative Agent, do, execute, acknowledge, deliver, record, re-record, file, re-file, register and re-register any and all such further acts, deeds, conveyances, pledge agreements, mortgages, deeds of trust, trust deeds, assignments, financing
statements and continuations thereof, termination statements, notices of assignment, transfers, certificates, assurances and other instruments as any Agent, or any Lender through the Administrative Agent, may reasonably require from time to time in
order to (A) carry out more effectively the purposes of the Collateral Documents, (B) to the fullest extent permitted by applicable law, subject any Loan Party’s or any of its Subsidiaries’ properties, assets, rights or interests to the
Liens now or hereafter intended to be covered by any of the Collateral Documents, (C) perfect and maintain the validity, effectiveness and priority of any of the Collateral Documents and any of the Liens intended to be created thereunder and (D)
assure, convey, grant, assign, transfer, preserve, protect and confirm more effectively unto the Secured Parties the rights granted or now or hereafter intended to be granted to the Secured Parties under any Collateral Document or under any other
instrument executed in connection with any Loan Document to which any Loan Party or any of its Subsidiaries is or is to be a party, and cause each of its Subsidiaries to do so. 
  
 SECTION 7.06 Collateral Agent Appointed Attorney-in-Fact. Each Borrower hereby irrevocably appoints the
Collateral Agent such Borrower’s attorney-in-fact, with full authority in the place and stead of such Borrower and in the name of such Borrower or otherwise, from time to time in the Collateral Agent’s discretion, upon the occurrence and
during the continuance of a Default or an Event of Default, to take any action and to execute any instrument, that the Collateral Agent, in its reasonable judgment, may deem necessary or advisable to accomplish the purposes of this Agreement,
including, without limitation, to make demand on the Receivables Payor or any Affiliate of any thereof for all amounts due under the Assigned Agreement to which it is a party, to receive, endorse and collect all instruments made payable to such
Borrower representing any payment or other distribution in respect of the Pledged Collateral or any part thereof and to give full discharge for the same, and to file any claims or take any action or institute any proceedings that the Collateral
Agent, in its reasonable judgment, may deem necessary or desirable for the collection of any of the Pledged Collateral or otherwise to enforce compliance with the terms and conditions of the Assigned Agreement or the rights of the Collateral Agent
with respect to any of the Pledged Collateral. 
  
 SECTION 7.07
Collateral Agent May Perform. If either Borrower fails to perform any agreement contained herein, the Collateral Agent may, but without any obligation to do so, itself perform, or cause performance of, such agreement, and the expenses
of the Collateral Agent incurred in connection therewith shall be payable by such Borrower under Article XI or Section 11.04. 
  
 SECTION 7.08 Reasonable Care. The powers conferred on the Collateral Agent hereunder are solely to protect its interest in the Pledged
Collateral and shall not impose any duty upon it to exercise any such powers. The Collateral Agent shall be deemed to have exercised 

  

 52 

 
reasonable care in the custody and preservation of the Pledged Collateral in its possession if the Pledged Collateral is accorded treatment substantially
equal to that which the Collateral Agent accords its own property, it being understood that the Collateral Agent shall have no responsibility for taking any necessary steps to preserve rights against any parties with respect to any Pledged
Collateral other than (i) the safe custody of any Pledged Collateral in its possession, (ii) the accounting for monies actually received by it hereunder and (iii) the application of monies in accordance with this Agreement. 
  
 SECTION 7.09 Rights, Remedies and Obligations. (a) The
Borrowers have agreed and have effectively and irrevocably instructed the Receivables Payor that all payments due or to become due to Enertec Exports under or in connection with the Assigned Agreement shall be made directly to the Collateral
Account. 
  
 (b) All payments received by Enertec Exports under or
in connection with the Assigned Agreement contrary to the provisions of this Agreement shall be received in trust for the benefit of the Collateral Agent, shall be segregated from other funds of Enertec Exports, and shall forthwith be paid over to
the Collateral Agent in the same form as so received (with any necessary endorsement). 
  
 SECTION 7.10 Remedies upon Default. If any Event of Default shall have occurred and be continuing: 
  
 (a) The Collateral Agent may exercise in respect of the Pledged Collateral, in addition to other rights and remedies provided for herein
or otherwise available to it, all the rights and remedies of a secured party under the Uniform Commercial Code (the “UCC”) in effect in the State of New York at that time (whether or not the UCC applies to the
Pledged Collateral at issue) to the fullest extent permitted under applicable law, and the Collateral Agent may also, without notice except as specified below, sell or liquidate the Pledged Collateral or any part thereof in one or more parcels at
public or private sale at any of the Collateral Agent’s offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as the Collateral Agent may deem commercially reasonable. Each Borrower agrees that, to the
extent notice of sale shall be required by law, at least ten days’ notice to such Borrower of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Collateral
Agent shall not be obligated to make any sale of Pledged Collateral or any part thereof regardless of notice of sale having been given. The Collateral Agent may adjourn any public or private sale from time to time by announcement at the time and
place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. 
  
 (b) Any cash held by the Collateral Agent as Pledged Collateral and all cash proceeds received by the Collateral Agent in respect of any
sale of, collection from, or other realization upon, all or any part of the Pledged Collateral shall be paid promptly after receipt thereof in whole or in part by the Collateral Agent pursuant to Section 8.04. 
  
 SECTION 7.11 Continuing Assignment and Security Interest; Transfer of
Advances. This Agreement shall create a continuing security interest in the Pledged Collateral 

  

 53 

 
and shall (i) remain in full force and effect until the payment in full of all Secured Obligations, (ii) be binding upon each Borrower and its successors and
assigns, and (iii) inure, together with the rights and remedies of the Lenders hereunder, to the benefit of the Lenders and their successors, transferees and assigns. Without limiting the generality of the foregoing clause (iii), any Lender may
assign any of its interest in the Advances to any other Person to the extent permitted by Article X, and such other Person shall thereupon become vested with all the benefits in respect thereof granted to the Lenders herein or otherwise. Upon the
payment in full of all Secured Obligations, each Borrower shall be entitled to the return, upon its request and at its expense, of such of the Pledged Collateral as shall not have been sold or otherwise applied pursuant to the terms hereof and the
Collateral Agent will execute and deliver such instruments, including UCC termination statements, as such Borrower may reasonably request to confirm the release and discharge of the Lien hereunder. 
  
 ARTICLE VIII 
  
 ADMINISTRATION AND SETTLEMENT OF THE COLLECTION ACCOUNT 
  
 SECTION 8.01 Establishment of the Account. Until the payment in
full of the Secured Obligations: 
  
 (a) The
Collateral Agent shall establish and, until payment in full of the Secured Obligations, maintain an account known as the “Enertec Receivables Financing Collateral Account” (the “Collateral
Account”), account number 129235.2, with JPMorgan Chase Bank, at its office at 4 New York Plaza, 15th Floor, New York, NY 10004, such Collateral Account bearing an additional designation clearly indicating that the funds deposited therein are held for the benefit of the Agents and the Lenders. All funds received by the
Collateral Agent in respect of or pursuant to the Assigned Agreement shall be deposited into the Collateral Account upon receipt thereof. The Collateral Account shall be an account of the Collateral Agent which shall be subject to the Collateral
Agent’s sole dominion and control. 
  
 (b)
It shall be a term and condition of the Collateral Account, and on or prior to the date hereof each Borrower shall give to the Collateral Agent written notice (such notice to be in form and substance satisfactory to the Lenders), that
notwithstanding any term or condition to the contrary in any other agreement relating to the Collateral Account, and except as otherwise provided in Section 7.01 or 8.04 hereof concerning transfers and payments or in Section 7.10 and 8.04 hereof
concerning payments after an Event of Default, no amount (including interest on Eligible Investments held in the Collateral Account) shall be paid or released from the Collateral Account to or for the account of, or withdrawn by or for the account
of, either Borrower or any other Person. The Collateral Account shall be subject to applicable laws, and applicable regulations of any competent banking or governmental authority, as may now or hereafter be in effect. 
  
 SECTION 8.02 Deposit of Funds into the Collateral Account. (a)
On or prior to the First Restatement Date, Enertec Exports gave to the Receivables Payor written notice (in the form of Exhibit D hereto) effectively and irrevocably instructing the Receivables Payor that all 

  

 54 

 
Receivables due to Enertec Exports under or in respect of the Assigned Agreement shall be deposited directly into the Collateral Account. 
  
 (b) The Agents shall notify each Borrower and the Lenders of any deposit made
pursuant to this Section 8.02 and shall provide to each Borrower and the Lenders monthly reports (and at the request and at the expense of any Lender such other periodic reports as such Lender may request) of holdings and transactions in the
Collateral Account. 
  
 SECTION 8.03 Investment of
Funds. (a) Available monies which are on deposit in the Collateral Account at the close of any Business Day shall be invested by the Collateral Agent (in its name credited to the related trust account for the benefit of the Person or
Persons specified herein or in the applicable supplement) based on written instructions signed by an Authorized Officer of each Borrower in Eligible Investments (provided that (i) in the absence of any such instructions, in investments of the type
set forth in clause (f) of the definition of Eligible Investments and (ii) if a Cash Collection Event has occurred and is continuing, in investments of the type set forth in clause (a) of the definition of Eligible Investments) maturing in the case
of monies on deposit in the Collateral Account (x) on or before the next Payment Date, if the entity serving as Collateral Agent or any Affiliate of the Collateral Agent is the obligor thereon, and (y) no later than the Business Day before the next
Payment Date, if a Person other than the entity serving as Collateral Agent or any Affiliate of the Collateral Agent is the obligor thereon, and, in any case, such Eligible Investments shall be held until their maturity. The Collateral Agent shall
not be liable for the selection of investments or for investment losses incurred thereon absent gross negligence or willful misconduct. Notwithstanding the requirement that investments be held until maturity, whenever the Collateral Agent is
required or permitted to make any payment, distribution or transfer under this Agreement, the Collateral Agent shall have the right, and is hereby irrevocably authorized, to sell or otherwise liquidate any Eligible Investments to the extent
necessary to make such payment or transfer and shall have no liability for and shall be fully protected from and against any losses incurred in connection with such sale or liquidation. 
  
 (b) Monies may remain temporarily uninvested to the extent that the Collateral Agent is instructed by the Borrowers to
purchase Eligible Investments which are unavailable because: (i) the deadline for purchasing such Eligible Investments on any Business Day is prior to the time the monies to be invested are available or (ii) such Eligible Investments are available
only in specific denominations and the available monies to be invested are not evenly divisible into such denominations; provided that, in the case of such event, the Collateral Agent shall make reasonable efforts to promptly give notice to
such Borrower of such occurrence. 
  

 55 

 SECTION 8.04 Allocation of Funds Deposited in the Collateral Account. Notwithstanding any
provision to the contrary contained herein, on each Business Day during the Collection Period relating to any Interest Period, promptly upon receipt by the Collateral Agent from the Receivables Payor of Receivables due in respect of the Assigned
Agreement, the Collateral Agent shall forthwith deposit the entire amount of such collections into the Collateral Account. Promptly following any deposit of collections into the Collateral Account, the Collateral Agent shall apply such collections
in the following order of priority: 
  

			
	 First,
	  	To the Administrative Agent’s Account until an amount equal to the Actual Debt Service Amount in respect of such Interest Period has been allocated the Administrative Agent’s
Account; provided that during the portion of any Collection Period relating to such Interest Period where the Eurodollar Rate for such Interest Period has not yet been determined, the Eurodollar Rate shall be deemed to be (solely for the
purposes of determining the amounts to be retained under this clause First) the Eurodollar Rate in effect for the next preceding Interest Period;
		
	 Second,
	  	To the Agents in an amount equal to, for each Agent, such Agent’s share of the Agent Expense Amount due to such Agent at such time; provided that if the amount available under this
clause Second is at any time less than the Agent Expense Amount at such time, then each Agent shall receive an amount equal to such Agent’s Agent Expense Amount Percentage multiplied by the total amount available under this clause
Second;
		
	 Third,
	  	To the Administrative Agent for distribution to the Lenders (which are not Defaulting Lenders) in an amount equal to, for each Lender, such Lender’s share of the Lender Expense Amount
due to such Lender at such time; provided that if the amount available under this clause Third is at any time less than the Lender Expense Amount at such time, then each Lender shall receive an amount equal to such Lender’s Lender
Expense Amount Percentage multiplied by the total amount available under this clause Third;
		
	 Fourth,
	  	If the Collateral Agent shall have actual knowledge or the Collateral Agent shall have received written notice that a Cash Collection Event shall have occurred and be continuing, then an
amount equal to the sum of the Actual Debt Service Amount for the Interest Period then commencing plus the Anticipated Debt Service Amount for the next succeeding Interest Period shall be retained in the Collateral Account during the Collection
Period corresponding to such Interest Period and, where such Cash Collection Event shall be continuing on the Payment Date corresponding to such Interest Period, all such funds retained pursuant to this clause Fourth shall be paid to the
Administrative Agent for application pursuant to Section 2.05(b)(i) hereto until the Collateral Agent shall have received notice from the Administrative Agent that all of the Borrowers’ Obligations hereunder have been satisfied in full;

 ARTICLE IX 
  
 THE AGENTS 
  
 SECTION 9.01 Authorization and Action. Each Lender hereby appoints and authorizes each Agent to take such action as agent on its behalf and to exercise such powers and discretion under this Agreement as are delegated to such
Agent by the terms hereof and thereof, together with such powers and discretion as are reasonably incidental thereto. As to any matters not expressly provided for by this Agreement (including, without limitation, enforcement or collection of the
Notes), no Agent shall be required to exercise any discretion or take any action (including, without limitation, giving any consent, undertaking any enforcement action or exercising any remedies), but shall be required to act or to refrain from
acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Required Lenders, and such instructions shall be binding upon all Lenders and all holders of Notes; provided, however, that no
Agent shall be required to take any action that exposes such Agent to personal liability or that is contrary to this Agreement or applicable law. Each Agent agrees to give to each Lender prompt notice of each notice given to it by any Borrower
pursuant to the terms of this Agreement. 
  
 SECTION 9.02
Agents’ Reliance, Etc. Neither any Agent nor any of their respective directors, officers, agents or employees shall be liable for any action taken or omitted to be taken by it or them under or in connection with the Loan Documents,
except for its or their own gross negligence or willful misconduct. Without limitation of the generality of the foregoing, each Agent: (a) may treat the payee of any Note as the holder thereof until, in the case of the Administrative Agent, the
Administrative Agent receives and accepts an Assignment and Acceptance entered into by the Lender that is the payee of such Note, as assignor, and an Eligible Assignee, as assignee, or, in the case of any other Agent, such Agent has received notice
from the Administrative Agent that it has received and accepted such Assignment and Acceptance, in each case as provided in Section 11.07; (b) may consult with legal counsel (including counsel for the Borrowers), independent public accountants and
other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (c) makes no warranty or 

  

 57 

 
representation to any Lender and shall not be responsible to any Lender for any statements, warranties or representations (whether written or oral) made in
or in connection with this Agreement; (d) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of this Agreement on the part of either Borrower or to inspect the property
(including the books and records) of either Borrower; (e) shall not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of, or the perfection or priority of any lien or security
interest created or purported to be created under or in connection with, any Loan Document or any other instrument or document furnished pursuant thereto; and (f) shall incur no liability under or in respect of any Loan Document by acting upon any
notice, consent, certificate or other instrument or writing (which may be by telegram, telecopy or telex) believed by it to be genuine and signed or sent by the proper party or parties. The Collateral Agent is entitled to rely upon any
certification, demand, notice or other writing delivered to it hereunder without being required to determine the correctness of any fact stated therein (including, without limitation, any certifications upon which the calculations of the Debt
Service Ratio or the Eligible Receivables Invoice Ratio may be based). In the event the Collateral Agent is in doubt as to what action it should take hereunder, it shall be entitled to request direction from the Lenders through the Administrative
Agent and shall be fully protected in acting or refraining from acting on the directions of the Required Lenders. 
  
 SECTION 9.03 Citibank, JPMorgan and Their Respective Affiliates. With respect to its Commitments, the Advances made by it and the Notes
issued to it, Citibank and JPMorgan shall have the same rights and powers under this Agreement as any other Lender and may exercise the same as though it were not an Agent; and the term “Lender” or “Lenders” shall, unless
otherwise expressly indicated, include Citibank and JPMorgan in their respective individual capacities, Citibank, JPMorgan and their respective affiliates may accept deposits from, lend money to, act as trustee under indentures of, accept investment
banking engagements from and generally engage in any kind of business with, any Loan Party and any Person that may do business with or own securities of any Loan Party, all as if Citibank and JPMorgan were not Agents and without any duty to account
therefor to the Lenders. 
  
 SECTION 9.04 Lender Credit
Decision. Each Lender acknowledges that it has, independently and without reliance upon any Agent or any other Lender and based on the financial statements referred to in Section 4.01 and such other documents and information as it has
deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon any Agent or any other Lender and based on such documents and information
as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement. 
  
 SECTION 9.05 Indemnification. (a) Each Lender severally agrees to indemnify each Agent (to the extent not promptly reimbursed by either
Borrower) from and against such Lender’s ratable share (determined as provided below) of any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever that may be imposed on, incurred by, or asserted against such Agent in any way relating to or arising out of this Agreement, the Notes, the Notice of Pledge or the Consent and Agreement or any action taken or omitted by such Agent under
this Agreement, the 

  

 58 

 
Notes, the Notice of Pledge or the Consent and Agreement; provided, however, that no Lender shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from such Agent’s gross negligence or willful misconduct as found in a final, non-appealable judgment by a court of
competent jurisdiction. Without limitation of the foregoing, each Lender agrees to reimburse each Agent promptly upon demand for its ratable share of any costs and expenses (including, without limitation, fees and expenses of counsel) payable by the
Borrowers under Section 11.04, to the extent that such Agent is not promptly reimbursed for such costs and expenses by either Borrower. 
  
 (b) For purposes of this Section 9.05, the Lenders’ respective ratable shares of any amount shall be determined, at any time, according to the sum of
the aggregate principal amount of the Advances outstanding at such time and owing to the respective Lenders. The failure of any Lender to reimburse any Agent promptly upon demand for its ratable share of any amount required to be paid by the Lenders
to such Agent as provided herein shall not relieve any other Lender of its obligation hereunder to reimburse such Agent for its ratable share of such amount, but no Lender shall be responsible for the failure of any other Lender to reimburse such
Agent for such other Lender’s ratable share of such amount. Without prejudice to the survival of any other agreement of any Lender hereunder, the agreement and obligations of each Lender contained in this Section 9.05 shall survive the payment
in full of principal, interest and all other amounts payable hereunder. 
  
 SECTION 9.06 Successor Agents. Any Agent may resign at any time by giving written notice thereof to the Lenders and each Borrower and may be removed at any time with or without cause by the Required Lenders. Upon any such
resignation or removal, the Required Lenders shall have the right to appoint a successor Agent. If no successor Agent shall have been so appointed by the Required Lenders, and shall have accepted such appointment, within 30 days after the retiring
Agent’s giving of notice of resignation or the Required Lenders’ removal of the retiring Agent, then the retiring Agent may, on behalf of the Lenders, appoint a successor Agent, which shall be a financial institution organized under the
laws of the United States or of any State thereof and having a combined capital and surplus of at least $250,000,000. Upon the acceptance of any appointment as Agent hereunder by a successor Agent and, in the case of a successor Collateral Agent,
upon the execution and filing or recording of such financing statements, or amendments thereto, and such other instruments or notices, as may be necessary or desirable, or as the Required Lenders may request, in order to continue the perfection of
the Liens granted or purported to be granted by this Agreement and by the Collateral Documents, such successor Agent shall succeed to and become vested with all the rights, powers, discretion, privileges and duties of the retiring Agent, and the
retiring Agent shall be discharged from its duties and obligations under the Loan Documents. If within 45 days after
written notice is given of the retiring Agent’s resignation or removal under this Section 9.06 no successor Agent shall have been appointed and shall have accepted such appointment, then on such 45th day (i) the retiring Agent’s
resignation or removal shall become effective, (ii) the retiring Agent shall thereupon be discharged from its duties and obligations under the Loan Documents and (iii) the Required Lenders shall thereafter perform all duties of the retiring Agent
under the Loan Documents until such time, if any, as the Required Lenders appoint a successor Agent as provided above. After any retiring Agent’s resignation or removal hereunder as Agent shall have 

  

 59 

 
become effective, the provisions of this Article IX shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under
this Agreement. 
  
 ARTICLE X 
  
 JOINT AND SEVERAL LIABILITY 
  
 SECTION 10.01 Joint and Several Liability. (a) Unless otherwise
specified herein, each Borrower agrees that it shall be jointly and severally liable for all of the Obligations of the Borrowers hereunder or under any other Loan Document, whether direct or indirect, absolute or contingent, and whether for
principal, interest, premiums, fees, indemnities, contract causes of action, costs, expenses or otherwise. Without limiting the generality of the foregoing, each Borrower’s liability shall extend to all amounts that constitute part of its
Obligations under the Loan Documents and would be owed by the other Borrower (such other Borrower in that capacity being herein referred to as the “Co-Borrower”) to any Secured Party
under or in respect of the Loan Documents but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving such Co-Borrower. 
  
 (b) For the purposes of this Agreement and the Notes, each of the Borrowers
shall be deemed to be the Co-Borrower and a co-obligor (obligado solidario) with respect to any of the Obligations of the other Borrowers hereunder and under the Notes, in accordance with Articles 1987, 1988 and 1989 of the Federal Civil Code
of Mexico (Código Civil Federal) and related articles contained in the civil codes of the relevant states of Mexico and the Federal District. 
  
 (c) The liability of each Borrower hereunder shall be irrevocable, absolute and unconditional irrespective of, and each Borrower hereby irrevocably waives
any defenses it may now have or hereafter acquire in any way relating to, any or all of the following: 
  
 (i) any lack of validity or enforceability of any Loan Document or any agreement or instrument relating thereto against its Co-Borrower;

  
 (ii) any taking, exchange, release or
non-perfection of any Pledged Collateral, or any taking, release or amendment or waiver of, or consent to departure from, any other guaranty, for all or any of the Borrowers’ Obligations under the Loan Documents without its prior consent;

  
 (iii) any manner of application of Pledged
Collateral, or proceeds thereof, to all or any of the Borrowers’ Obligations under the Loan Documents; 
  
 (iv) any change, restructuring or termination of the corporate structure or existence of any Borrower or any of its Subsidiaries;

  
 (v) any failure of any Secured Party to
disclose to any Loan Party any information relating to the business, condition (financial or otherwise), operations, performance, properties or prospects of any other Loan Party now or hereafter known to 

  

 60 

 
such Secured Party (each Borrower waiving any duty on the part of the Secured Parties to disclose such information); 
  
 (vi) any other circumstance (including, without limitation,
any statute of limitations) or any existence of or reliance on any representation by any Secured Party that might otherwise constitute a defense of a surety or guarantor available to, or a discharge of, any Loan Party in respect of a Co-Borrower.

  
 SECTION 10.02 Waivers and Acknowledgments. (a)
Each Borrower hereby unconditionally and irrevocably waives promptness, diligence, notice of acceptance, presentment, demand, protest or dishonor and any other notice with respect to any of its Obligations under the Loan Documents not otherwise
expressly required under the terms of the Loan Documents or exhaust any right or take any action against any Co-Borrower or any other Person or any Pledged Collateral. 
  
 (b) Each Borrower hereby unconditionally and irrevocably waives (i) any defense arising by reason of any claim or defense
based upon an election of remedies by any Secured Party that in any manner impairs, reduces, releases or otherwise adversely affects the subrogation, reimbursement, exoneration, contribution or indemnification rights of such Borrower or other rights
of such Borrower to proceed against any Co-Borrower or any other Person or any Pledged Collateral. 
  
 (c) Each Borrower hereby unconditionally and irrevocably waives any duty on the part of any Secured Party to disclose to such Borrower any matter, fact or
thing relating to the business, condition (financial or otherwise), operations, performance, properties or prospects of any Co-Borrower or any of its Subsidiaries now or hereafter known by such Secured Party. 
  
 (d) Each Borrower acknowledges that it will receive substantial direct and
indirect benefits from the financing arrangements contemplated by the Loan Documents and that the waivers set forth in Section 10.01 and this Section 10.02 are knowingly made in contemplation of such benefits. 
  
 SECTION 10.03 Subrogation and Contribution. Each Borrower
hereby unconditionally and irrevocably agrees not to exercise any rights that it may now have or hereafter acquire against a Co-Borrower that arise from the existence, payment, performance or enforcement of such Borrower’s Obligations under or
in respect of the Loan Documents, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate in any claim or remedy of any Secured Party against the Co-Borrower
or any Pledged Collateral, whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including, without limitation, the right to take or receive from the other Borrower party hereto or any other Loan
Party, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim, remedy or right, unless and until all of the Borrowers’ Obligations under the Loan Documents shall have
been paid in full in cash and shall have expired or been terminated and the Commitments shall have expired or been terminated. Notwithstanding the foregoing, so long as no Default shall exist and be continuing before and after giving effect to a
payment, a Borrower may receive payment in the nature of a reimbursement, contribution or 

  

 61 

 
subrogation payment from a Co-Borrower within five Business Days of the date the Obligation is paid. 
  
 If any amount shall be paid to either Borrower in violation of the
immediately preceding paragraph at any time prior to the payment in full in cash of all amounts payable under the Loan Documents, such amount shall be received and held in trust for the benefit of the Secured Parties, shall be segregated from other
property and funds of such Borrower and shall forthwith be paid or delivered to the Administrative Agent in the same form as so received (with any necessary endorsement or assignment) to be credited and applied to the Borrowers’ Obligations
under the Loan Documents, whether matured or unmatured, in accordance with the terms of the Loan Documents, or to be held by the Collateral Agent as Pledged Collateral for any Obligations or other amounts payable under the Loan Documents thereafter
arising. If (i) any Borrower shall make payment to any Secured Party of all or any part of its Obligations under the Loan Documents and (ii) all of the Borrowers’ Obligations under the Loan Documents shall have been paid in full in cash, the
Secured Parties will, at such Borrower’s request and expense, execute and deliver to such Borrower appropriate documents, without recourse and without representation or warranty, necessary to evidence the transfer by subrogation or contribution
to such Borrower of an interest in the Obligations of the Borrowers under the Loan Documents resulting from such payment made by such Borrower pursuant hereto.

 (b) The Borrowers agree to indemnify and hold harmless each Agent, each Lender and each of their Affiliates and their respective officers, directors, employees, agents and advisors (each, an “Indemnified
Party”) from and against any and all claims, damages, losses, liabilities and expenses (including, without limitation, reasonable fees and expenses of counsel) that may be incurred by or asserted or awarded against

investigation, litigation or other proceeding to which the indemnity in this Section 11.04(b) applies, such indemnity shall be effective whether or not such investigation, litigation or proceeding is brought by any Borrower, its directors,
shareholders or creditors or an Indemnified Party or any Indemnified Party is otherwise a party thereto and whether or not the transactions contemplated by the Loan Documents are consummated. Each Borrower also agrees not to assert any claim against
any Agent, any Lender or any of their Affiliates, or any of their respective officers, directors, employees, attorneys and agents, on any theory of liability, for special, indirect, consequential or punitive damages arising out of or otherwise
relating to the actual or proposed use of the proceeds of the Advances, the Loan Documents or any of the transactions contemplated by the Loan Documents; provided that such waiver does not affect the obligation of the Lenders to act in good

and expenses of counsel and indemnities, such amount may be paid on behalf of the Borrowers by the Agents or any Lender, if such Agent or Lender determines, after consultation with the Borrowers, that such amount is not in dispute and that such
amount is required to be paid to preserve such Agent’s or such Lender’s interests under the Loan Documents, or, in the case of either Agent, the interests of the Lenders as a whole under the Loan Documents. 
  
 (e) Without prejudice to the survival of any other agreement of the Borrowers

(general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Agent, such Lender or such Affiliate to or for the credit or the account of the Borrowers against any and all of the
Obligations of the Borrowers now or hereafter existing under this Agreement and the Notes, irrespective of whether such Agent or such Lender shall have made any demand under this Agreement or such Note or Notes and although such obligations may be
unmatured. Each Agent and each Lender agrees promptly to notify the Borrowers after any such set-off and application; provided, however, that the failure to give such notice shall not affect the validity of such set-off and
application. The rights of each Agent and each Lender and their respective Affiliates under this Section are in addition to other rights and remedies (including, without limitation, other rights of set-off) that such Agent, such Lender and their
respective Affiliates may have.

value of, or the perfection or priority of any lien or security interest created or purported to be created under or in connection with, any Collateral Document or any other instrument or document furnished pursuant thereto; (ii) such assigning
Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrowers or the performance or observance by the Borrowers of any of its obligations under any Loan Document to which it is a
party or any other instrument or document furnished pursuant thereto; (iii) such assignee confirms that it has received a copy of this Agreement, together with copies of the financial statements referred to in Section 4.01 and such other documents
and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (iv) such assignee will, independently and without reliance upon any Agent, such assigning Lender or any other
Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (v) such assignee 

  

 66 

 
confirms that it is an Eligible Assignee; (vi) such assignee appoints and authorizes each Agent to take such action as agent on its behalf and to exercise
such powers and discretion under this Agreement as are delegated to such Agent by the terms hereof and thereof, together with such powers and discretion as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in
accordance with their terms all of the obligations that by the terms of this Agreement are required to be performed by it as a Lender, as the case may be. 
  
 (d) The Administrative Agent, acting for this purpose (but only for this purpose) as the agent of the Borrowers, shall maintain at its address referred to
in Section 11.02 a copy of each Assignment and Acceptance delivered to and accepted by it and a register for the recordation of the names and addresses of the Lenders and the Commitment of, and principal amount of the Advances owing to, each Lender
from time to time (the “Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Borrower, the Agents and the Lenders shall treat each Person whose
name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrowers or any Agent or any Lender at any reasonable time and from time to time upon reasonable prior
notice. 
  
 (e) Upon its receipt of an Assignment and Acceptance
executed by an assigning Lender and an assignee, together with any Note or Notes subject to such assignment, the Administrative Agent shall, if such Assignment and Acceptance has been completed and is in substantially the form of Exhibit C of this
Agreement, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the Borrowers and each other Agent. In the case of any assignment by a Lender, within five
Business Days after its receipt of such notice, the Borrowers, at its own expense, shall execute and deliver to the Administrative Agent in exchange for the surrendered Note or Notes a new Note to the order of such Eligible Assignee in an amount
equal to the Commitment assumed by it pursuant to such Assignment and Acceptance and, if any assigning Lender has retained a Commitment under this Agreement, a new Note to the order of such assigning Lender in an amount equal to the Commitment
retained by it under this Agreement. Such new Note or Notes shall be in an aggregate principal amount equal to the aggregate principal amount of such surrendered Note or Notes, shall be dated the effective date of such Assignment and Acceptance and
shall otherwise be in substantially the form of Exhibit A of this Agreement, as the case may be. 
  
 (f) Each Lender may sell participations to one or more Persons (other than the Borrowers or any of their Affiliates) in or to all or a portion of its
rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitments, the Advances owing to it and the Note or Notes (if any) held by it); provided, however, that (i) such Lender’s
obligations under this Agreement (including, without limitation, its Commitments) shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties to this Agreement for the performance of such obligations, (iii) such
Lender shall remain the holder of any such Note for all purposes of this Agreement, (iv) the Borrowers, the Agents and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and
obligations under this Agreement and (v) no participant under any such participation shall have any right to approve any amendment or waiver of any provision of this Agreement, or any consent to any departure by the Borrowers therefrom, except to
the extent that such 

  

 67 

 
amendment, waiver or consent would reduce the principal of, or interest on, the Notes or any fees or other amounts payable under this Agreement, in each case
to the extent subject to such participation, postpone any date fixed for any payment of principal of, or interest on, the Notes or any fees or other amounts payable under this Agreement, in each case to the extent subject to such participation, or
release all or substantially all of the Pledged Collateral. 
  
 (g) Any Lender may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 11.07, disclose to the assignee or participant or proposed assignee or participant any information
relating to the Borrowers furnished to such Lender by or on behalf of the Borrowers; provided, however, that, prior to any such disclosure, the assignee or participant or proposed assignee or participant shall agree to preserve the
confidentiality of any Confidential Information received by it from such Lender. 
  
 (h) Notwithstanding any other provision set forth in this Agreement, any Lender may at any time create a security interest in all or any portion of its rights under this Agreement (including, without limitation, the
Advances owing to it and the Note or Notes held by it) in favor of any Federal Reserve Bank in accordance with Regulation A of the Board of Governors of the Federal Reserve System. 
  
 SECTION 11.08 Severability. The invalidity, illegality, or unenforceability in any jurisdiction of any
provision under this Agreement shall not affect or impair the remaining provisions of this Agreement. 
  
 SECTION 11.09 Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties to this
Agreement in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Manual delivery of an executed counterpart of a signature page to this
Agreement by telecopier shall be effective as delivery of an original executed counterpart of this Agreement. 
  
 SECTION 11.10 Confidentiality. Neither any Agent nor any Lender shall disclose any Confidential Information to any Person without the
consent of the Borrowers, other than (a) to such Agent’s or such Lender’s Affiliates and their officers, directors, employees, agents and advisors and to actual or prospective Eligible Assignees and participants in accordance with Section
11.07(g) hereof, (b) as required by any law, rule or regulation or judicial process, and (c) as requested or required by any state, federal or foreign authority or examiner regulating such Lender. 
  
 SECTION 11.11 Release of Pledged Collateral. Upon the sale,
lease, transfer or other disposition of any item of Pledged Collateral, other than the Assigned Agreement, of any Borrower (including, without limitation, as a result of the sale, in accordance with the terms of the Loan Documents, of the Loan Party
that owns such Pledged Collateral) in accordance with the terms of the Loan Documents, the Collateral Agent will, at the direction of the Administrative Agent and at the Borrowers’ expense, execute and deliver to the Borrowers such documents as
the Borrowers may reasonably request to evidence the release of such item of Pledged Collateral from the assignment and security interest granted under the Collateral Documents in accordance with the terms of the Loan Documents. 
  

 68 

 SECTION 11.12 Administrative Agent. The Required Lenders hereby acknowledge and agree to the
removal of ING as Administrative Agent and the appointment of Citibank, N.A. as successor administrative agent in accordance with Section 9.06 hereto. Citibank, N.A. hereby accepts such appointment on the terms and conditions set forth in this
Agreement. 
  
 SECTION 11.13 Jurisdiction, Etc. (a) Each of
the parties hereto hereby irrevocably and unconditionally submits, for itself and its property, to the jurisdiction of any New York state court or federal court of the United States sitting in New York City, and any appellate court from any thereof,
and to the courts of its own corporate domicile with respect to actions brought against it as a defendant, in any action or proceeding arising out of or relating to each Loan Document to which it is a party, or for recognition or enforcement of any
judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in any such New York state court or, to the extent permitted by law, in
such federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Each Borrower
hereby irrevocably appoints by means of a public instrument issued before a Mexican public notary CT Corporation System (the “Process Agent”) with an office on the date of this Agreement (as amended and
restated) at 111 Eighth Avenue, New York, New York 10011, United States, as its agent to receive on behalf of such Borrower and its property service of copies of the summons and complaint and any other process which may be served in any such action
or proceeding. Such service may be made by delivering a copy of such process to such Borrower in care of the Process Agent at the Process Agent’s above address, and such Borrower hereby irrevocably authorizes and directs the Process Agent to
accept such service on its behalf. As an alternative method of service, each Borrower also irrevocably consents to the service of any and all process in any such action or proceeding by sending copies of such process by mail (by method requiring
evidence of receipt) with a second copy to be sent to such Borrower by courier at its address specified in Section 11.02. 
  
 (b) Each of the parties hereto irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection that it
may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or the Notes in any New York state or federal court. Each of the parties hereto hereby irrevocably waives, to the fullest
extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding and all rights of jurisdiction in any such action or proceeding which they may now or hereafter have by reason of their present or any
future domicile or otherwise. 
  
 (c) To the extent that either
Borrower has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service of notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to
itself or its property, such Borrower hereby irrevocably waives such immunity in respect of its obligations under this Agreement and the Notes and, without limiting the generality of the foregoing, agrees that the waivers set forth in this
subsection (c) shall have the fullest scope permitted under the Foreign Sovereign Immunities Act of 1976 of the United States and are intended to be irrevocable for purposes of such Act. 
  

 69 

 SECTION 11.14 Governing Law. This Agreement shall be governed by, and construed in
accordance with, the laws of the State of New York. 
  
 SECTION
11.15 Waiver of Jury Trial. Each of the Borrowers, the Agents and the Lenders hereby irrevocably waives all right to trial by jury in any action, proceeding or counterclaim (whether based on contract, tort or otherwise) arising out of
or relating to this Agreement, the Advances, the Notes or the transactions contemplated hereby or thereby or the actions of the Agents or any Lender in the negotiation, administration, performance or enforcement thereof. 
  
 SECTION 11.16 Judgment. (a) If for purposes of obtaining
judgment in any court it is necessary to convert a sum due hereunder or under the Notes in U.S. Dollars into another currency, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be
that at which in accordance with normal banking procedures the Administrative Agent could purchase U.S. Dollars with such other currency at New York City on the Business Day preceding that on which final judgment is given. 
  
 (b) The obligation of the Borrowers in respect of any sum due from it to the
Administrative Agent or any Lender, as the case may be, hereunder or under the Notes shall, notwithstanding any judgment in a currency other than U.S. Dollars, be discharged only to the extent that on the Business Day following receipt by the
Administrative Agent or such Lender of any sum adjudged to be so due in such other currency the Administrative Agent or the Lender, as the case may be, may in accordance with normal banking procedures purchase U.S. Dollars with such other currency;
if the U.S. Dollars so purchased are less than the sum originally due to the Administrative Agent or the Lender, as the case may be, in U.S. Dollars, the Borrowers agree, as a separate obligation and notwithstanding any such judgment, to indemnify
the Administrative Agent or the Lender, as the case may be, against such loss, and if the U.S. Dollars so purchased exceed the sum originally due to the Administrative Agent or the Lender, as the case may be, in U.S. Dollars, the Administrative
Agent or the Lender, as the case may be, agrees to remit to the Borrowers, for deposit in the Borrowers’ Account, such excess.

 Ladies and Gentlemen: 
  
 I am Vice President and General Counsel of Johnson Controls Battery Group, Inc., a Wisconsin Corporation
(“JCBG”). I am delivering this opinion in connection with the execution and delivery by JCBG of the Battery Supply Agreement Amendment, as hereinafter defined, and the
Consent and Agreement, each dated as of October 31, 2002, in connection with the execution of the Amended and Restated Credit and Security Agreement (the “Amended and Restated Credit and Security
Agreement”, all terms not otherwise defined herein shall be used herein as defined in the Amended and Restated Credit and Security Agreement) dated as of October 31, 2002 among Enertec Mexico, S. de R.L. de
C.V. (“Enertec”), Enertec Exports, S. de R.L. de C.V. (“Enertec
Exports”, and together with Enertec, the “Borrowers” and individually, each a
“Borrower”), the Lenders named therein, JPMorgan Chase Bank and ING (U.S.) Capital LLC. 
  
 In furnishing this opinion, I have examined originals or copies, certified or
otherwise identified to my satisfaction as being true copies, of (a) the Certificate of Incorporation and By-laws of JCBG, (b) the Notice of Pledge, dated as of October 31, 2002 given by Enertec Exports to JCBG, and acknowledged by JPMorgan Chase
Bank and ING (U.S.) Capital LLC, (c) the Consent and Agreement, dated as of October 31, 2002, executed and delivered by JCBG and acknowledged by JPMorgan Chase Bank (the “Consent and

officers and other representatives of JCBG and of public officials and (g) such other documents as I deemed necessary or appropriate as a basis for the opinions set forth herein. 
  
 In my examination I have assumed the genuineness of all signatures, the legal capacity of natural persons, the completeness
and authenticity of all documents submitted to me as originals, the conformity to original documents of all documents submitted to me as certified or photostatic copies and the authenticity of the originals of such copies. As to various questions of
fact material to this opinion I have relied upon the certificates, statements and representations of officers and other representatives of JCBG. 
  
 I am admitted to practice law in the State of Wisconsin and as such I do not purport to be an expert on, or to express any opinion herein concerning any
law other than the laws of the State of Wisconsin and the federal laws of the United States of America. 
  
 Based on the foregoing and subject to the qualifications set forth herein, I am of the opinion that: 
  
 1. JCBG is a corporation duly incorporated, validly existing
and in good standing under the laws of the State of Wisconsin, has the corporate power to own its properties and conduct its business as now being conducted and is duly qualified and/or licensed to transact business in every jurisdiction in which
the failure to be so qualified or licensed would have a material adverse effect on JCBG.

Agreement has been duly authorized by all necessary corporate action on the part of JCBG. JCBG has duly executed and delivered each such document, and each such document is the legal, valid and binding obligation of JCBG, enforceable against JCBG in
accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency,

 EXHIBIT E 
 Form Of
Opinion Of Enrique Gonzales 
  
 To the Agents and Initial Lenders party to the
Second Amended 

	  	and Restated Credit and Security Agreement referred to below 

  
 Enertec México, S. de R.L. de C.V.  
 Enertec Exports, S. de R.L. de C.V. 
  
 Ladies and Gentlemen:

  
 I make reference to the Second Amended and Restated Credit and
Security Agreement dated as of March 15, 2004 (the “Second Amended and Restated Credit and Security Agreement”) among Enertec México, S. de R.L. de C.V., a Mexican sociedad de responsabilidad limitada de capital
variable (“Enertec”), Enertec Exports, S. de R.L. de C.V., a Mexican sociedad de responsabilidad limitada de capital variable (“Enertec Exports”, and together with Enertec, the
“Borrowers” and individually, each a “Borrower”), the Initial Lenders therein identified, Citibank, N.A., as Administrative Agent, and JPMorgan Chase Bank, as Collateral Agent. Terms defined in the Second Amended
and Restated Credit and Security Agreement unless otherwise defined herein are used herein as defined in the Second Amended and Restated Credit and Security Agreement. This opinion is furnished to you pursuant to Section 3.01(a)(vi) of the Second
Amended and Restated Credit and Security Agreement. 
  
 I have
acted as Mexican counsel for the Borrowers in connection with the execution, preparation and delivery of the Second Amended and Restated Credit and Security Agreement and related documentation. In that connection, I have examined the execution copy
of the Second Amended and Restated Credit and Security Agreement, the New Notes, the Notice of Pledge, the Consent and Agreement and the Assigned Agreement (collectively, the “Loan Documents”). 
  
 In addition, I have examined and relied upon originals or copies, certified
or otherwise identified to my satisfaction, of such other documents as I have deemed appropriate for purposes of this opinion. In my examination of the documents referred to above, I have assumed the authenticity of all such documents submitted to
me as originals, the genuineness of all signatures, the due authority of the parties executing such documents, and the conformity to the originals of all such documents submitted to me as copies. I have also assumed that each of the parties (other
than the Borrowers) to the Loan Documents has duly executed and delivered, with all necessary power and authority (corporate and otherwise), each of the Loan Documents to which it is a party. 
  

 Based upon the foregoing and upon such other investigation as I have deemed necessary, I am of the
opinion that: 
  
 1. Each Borrower is a
sociedad de responsabilidad limitada de capital variable duly incorporated and validly existing under the laws of Mexico and has all requisite corporate power and authority to own, lease and operate its properties and to carry on its
business as it is currently conducted and is proposed to be conducted. 
  
 2. The execution, delivery and performance by each Borrower of the Loan Documents to which it is a party and the consummation of the transactions contemplated thereby are within the corporate powers of such Borrower,
have been duly authorized by all necessary corporate action, and do not (a) contravene such Borrower’s estatutos sociales or any contractual restriction binding on or affecting such Borrower or (b) conflict with or result in the breach
of, or constitute a default under, any agreement or instrument or (c) except for the Liens created by the Collateral Documents, result in or require the creation or imposition of any Lien upon or with respect to, any of the properties of such
Borrower. 
  
 3. No authorization, approval or
other action by, and no notice to or filing with, any governmental authority or regulatory body or, to my knowledge, other third party is required to be obtained or made by either Borrower for (a) the execution, delivery or performance by either
Borrower of the Loan Documents to which it is a party, (b) the granting by either Borrower of the Liens pursuant to the Collateral Documents to which it is a party, (c) the perfection or maintenance of the Liens created by the Collateral Documents
(including the first priority nature thereof), or (d) the exercise by any Agent or any Lender of its rights under the Loan Documents or the remedies in respect of the Collateral pursuant to the Collateral Documents. 
  
 4. Each Loan Document to which each Borrower is a party
(other than the New Notes) has been, and each of the New Notes, when delivered hereunder, will have been, duly executed and delivered by such Borrower. 
  
 5. Each Borrower is in compliance with all applicable Mexican laws and regulations (including all decrees and orders of, or agreements
with, any Mexican governmental, administrative or judicial authorities) relating to the environment, hazardous or toxic substances, wastes, pollutants or contaminants or health and safety, except for any such non-compliance that could not,
individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. There are no proceedings by or against either Borrower or, to the best of my knowledge, threatened, involving such laws or regulations or alleging violations
or non-compliance of any such laws or regulations that could, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. 
  

 6. Each Loan Document to which each Borrower is a party (other than the New Notes)
constitutes, and each of the New Notes, when delivered hereunder, will constitute, a valid and binding agreement of such Borrower, enforceable against such Borrower in accordance with its terms. 
  
 7. The Second Amended and Restated Credit and Security
Agreement is effective to create in favor of the Collateral Agent, for the benefit of the Agents and the Lenders, a valid security interest in the Pledged Collateral, securing payment of the Secured Obligations. 
  
 8. The security interest referred to in paragraph 7 above,
to the extent that such security interest relates to the Assigned Agreement and any proceeds therefrom, is and has been perfected by sending the Notice of Pledge to the Receivables Payor and receipt by the Collateral Agent of the duly executed
Consent and Agreement. 
  
 9. The security
interest referred to in paragraph 7 above is a first priority security interest. 
  
 10. No filing, recording, authorization, registration, notarization, qualification or other action of or with any Mexican registry or
governmental agency or body is necessary and no other action is required other than the execution of the Notice of Pledge and the Consent and Agreement in order to perfect the security interests created on the Pledged Collateral pursuant to the
Assigned Agreement in favor of the Initial Lenders. 
  
 11. The place of business and chief executive office of each Borrower is in Mexico and neither Borrower has a place of business in the United States. 
  

My opinion above is subject to the following qualifications: 
  

(a) My opinion in each of paragraphs 2 (to the extent that it relates to performance by each Borrower of its obligations under the Loan
Documents to which it is a party), 5 and 6 above is subject to the effect of any applicable bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium or similar laws affecting
creditors’ rights generally and to possible judicial action giving effect to governmental actions or foreign laws affecting creditors’ rights. 
  
 (b) My opinions expressed above are limited to the laws of Mexico. 
  
 This opinion may not be used or relied upon by any person except the addressees hereof and may not be furnished to, quoted
or relied upon by any other person or entity for any purpose without my prior written consent; provided, however, that persons who subsequent to the date hereof become Lenders, in accordance with Section 11.07 of the Second Amended and Restated
Credit and Security Agreement, may rely on this letter as of the time of its delivery on 

  

 3 

 
the date hereof as if this letter were addressed to them. This opinion may also be delivered to Shearman & Sterling LLP, counsel to the Administrative
Agent, who may rely on this opinion to the same extent as if such opinion were addressed to them. 
  

	
	 Very truly yours,

	
	 
	 Lic. J. Enrique Gonzalez G.

Form Of Opinion Of Ritch, Heather y Mueller, S.C. 
  
 RITCH, HEATHER Y MUELLER, S.C. 
  
 March 15, 2004 
  
 To the Agents and the Initial Lenders party to the 
 Second Amended and Restated Credit and Security Agreement 
 referred to below 
  
 Ladies and Gentlemen: 
  
 We have
acted as Mexican counsel to Citibank, N.A., as administrative agent (the “Administrative Agent”), in connection with the execution and delivery of the Second Amended and Restated Credit and Security Agreement dated as of March 15,
2004 (the “Credit and Security Agreement”) among Enertec Mexico, S. de R.L. de C.V. and Enertec Exports, S. de R. L. de C.V. (each a “Borrower” and together, the “Borrowers”), the Administrative
Agent, JPMorgan Chase Bank (“Chase”), as Collateral Agent and the Initial Lenders therein identified. This opinion is furnished to you pursuant to Section 3.01(a)(viii) of the Credit and Security Agreement. Capitalized terms used
herein and not otherwise defined shall have the meanings ascribed thereto in the Credit and Security Agreement. 
  
 In connection with this opinion, we have examined and have relied on originals or copies, certified or otherwise identified to our satisfaction, of such
documents as we have deemed necessary or appropriate as a basis for the opinion hereinafter set forth, including: 
  

	 	(a)	the Credit and Security Agreement; 

  

	 	(b)	the form of the Notes; 

  

	 	(c)	certified copies of the current by-laws (estatutos sociales) of each Borrower; 

  

	 	(d)	certified copies of the powers-of-attorney granted to officers of each Borrower, and 

  

	 	(e)	all such corporate records, documents and other instruments of the Borrowers, certificates or comparable documents of public officials and of officers and representatives of the
Borrowers and agreements, instruments and other documents as we have deemed necessary for the opinion rendered below. 

  

 All documents reviewed by us under sections (c), (d), and (e) above are listed in Exhibit A
hereto. 
  
 As to questions of fact material to such opinion, we
have, when relevant facts were not independently known or established by us, relied upon certificates of the Borrowers, its officers or public officials. We have not reviewed any certificate or instrument issued by any public registry, including the
public registry of commerce. 
  
 We have assumed, without any
independent investigation or verification of any kind, (i) the genuineness of all signatures, the authenticity of all documents submitted to us as originals and the conformity to authentic original documents of all documents submitted to us as
certified, conformed or photostatic copies, (ii) the due authority of, and the due execution by, the parties (other than the Borrowers) executing each of the Credit and Security Agreement and the Notes (collectively, the “Loan
Documents”), (iii) the accuracy of the representations and warranties of the Borrowers provided in the Loan Documents, (iv) the solvency of the Borrowers and that the transactions contemplated under the Loan Documents do not constitute
fraudulent conveyance of the Borrowers in accordance to Mexican applicable federal law, (v) that the documents listed in Exhibit A hereto have not been further amended, and that the powers-of-attorney contained therein have not been revoked
or limited in any manner, and (vi) the validity, binding effect and enforceability of the Loan Documents under the laws of the State of New York, United States of America and any other laws other than the laws of the United Mexican States
(“Mexico”). 
  
 We have made no independent
investigation of the laws of the United States of America, any state thereof or any other laws other than the laws of Mexico as a basis for the opinion stated herein and we have assumed that there is nothing in any such laws that affects our
opinion. 
  
 Based upon the foregoing, we are of the opinion that:

  
 1. Each Borrower has been duly incorporated and is validly
existing as a sociedad de responsabilidad limitada de capital variable under the laws of Mexico. 
  
 2. The Loan Documents have been duly authorized, executed and delivered by the Borrowers and constitute the legal, valid and binding obligations of the
Borrowers, enforceable in accordance with their respective terms. 
  
 3. The Notes evidencing the Borrowings, when executed and delivered by each of the Borrowers for value, will constitute the legal, valid and binding obligations of the Borrowers, enforceable against the Borrowers in accordance with their
respective terms. 
  
 4. No authorization, approval or other
action by, and no notice to or filing with any governmental authority or regulatory body in Mexico is required for the execution, delivery or performance by each of the Borrowers of each of the Loan Documents. 
  

 2 

 5. The execution, delivery and performance by each of the Borrowers of each of the Loan Documents to
which it is a party, and the consummation of the transactions contemplated thereby, (i) are within the corporate powers of each such Borrower and do not contravene such Borrower’s estatutos sociales and (ii) do not result in any
violation of any applicable Mexican federal law, rule or regulation known to us. 
  
 6. The obligations of each of the Borrowers under the Loan Documents do rank and will, under current law, rank at least part passu in priority of payment with all other unsecured indebtedness of the Borrowers.

  
 7. There is no tax, impost, deduction or withholding imposed
by Mexico or by any political subdivision or taxing authority thereof or therein either (i) on or by virtue of the execution or delivery of the Loan Documents, or (ii) on any payment to be made by the Borrower pursuant to any Loan Document
except for withholding taxes on payments of interest, fees, and other amounts deemed interest and indemnity payments to a non-residents of Mexico. 
  
 8. No approval authorization, filing or registration of or with any Mexican governmental authority is required for (a) the due execution, delivery or
performance by each Borrower of each of the Loan Documents or for the consummation of the transactions contemplated thereby, or (b) the exercise by the Agents or any Initial Lender of its rights under the Loan Documents. 
  
 9. None of the Agents or any Initial Lender is required to be qualified to do
business in Mexico to carry out the transactions contemplated by the Loan Documents or to avail themselves of the remedies provided thereby, nor will the Agents or any Initial Lender be subject to taxation in Mexico (except as set forth in
paragraph 7 above), solely as a result of the transactions contemplated by the Loan Documents. 
  
 10. The choice of New York law to govern the Loan Documents which are expressed to be governed by New York law is, under the laws of Mexico, a valid and effective choice of law and a Mexican court would give effect to
such choice of law. 
  
 11. The submission by each Borrower to the
jurisdiction of any New York State or United States Federal court sitting in the City of New York, New York, United States of America, and the appointment of CT Corporation System as Process Agent to receive service of process on behalf of the
Borrowers as set forth in the Loan Documents are valid, binding and enforceable against the Borrowers under the laws of Mexico. 
  

 3 

 12. Any final judgment obtained against any of the Borrowers in any of the courts mentioned in paragraph
11 above, pursuant to a legal action instituted before any such courts in connection with any of the Loan Documents would be valid and enforceable, without re-examination of the issues, pursuant to Articles 569 and 571 of the Federal Code of Civil
Procedure and Article 1347A of the Commerce Code, which provide, inter alia, that any judgment rendered outside Mexico may be enforced by Mexican courts, provided that: 
  

	 	(a)	such judgment is obtained in compliance with legal requirements of the jurisdiction of the court rendering such judgment and in compliance with all legal requirements of such Loan
Documents; 

  

	 	(b)	such judgment is strictly for the payment of a certain sum of money and has not been rendered in an in rem action (acción real); 

  

	 	(c)	service of process is made personally on the Borrowers or on the duly appointed process agent; 

  

	 	(d)	such judgment does not contravene Mexican law, public policy of Mexico, international treaties or agreements binding upon Mexico, except as described in the qualifications set forth
below, we have no reason to believe that that the Loan Documents contravene Mexican law, public policy of Mexico, international treaties or agreements binding upon Mexico); 

  

	 	(e)	the applicable procedural requirements under the laws of Mexico with respect to the enforcement of foreign judgments (including the issuance of letters rogatory by the competent
authority of such jurisdiction requesting enforcement of such judgment and the certification of such judgment as authentic by the corresponding authorities of such jurisdiction in accordance with the laws thereof) are complied with;

  

	 	(f)	such judgment is final in the jurisdiction where obtained; 

  

	 	(g)	the action in respect of which such judgment is rendered is not the subject matter of a lawsuit among the same parties, pending before a Mexican court; and 

 

	 	(h)	the courts of such jurisdiction recognize the principles of reciprocity in connection with the enforcement of Mexican judgments in such jurisdiction. 

  
 13. Each Borrower is subject to civil and commercial law with respect to its
obligations under each Loan Document to which it is a party, and the execution, delivery and performance by each Borrower of its obligations under each Loan Document constitute private and commercial acts rather than public or governmental acts.
Neither Borrower nor any of their property is entitled to any immunity from the jurisdiction of any court in connection with the Loan Documents (including, without limitation, immunity from service of process or notice, immunity from jurisdiction of
any court or tribunal, immunity from attachment prior to entry of judgment or in aid of execution upon a judgment, execution or otherwise) in respect of themselves or their properties. 
  

 4 

 The foregoing opinion is subject to the following qualifications: 
  
 (i) enforcement of the Loan Documents may be limited by bankruptcy,
insolvency, concurso mercantil, insolvency, liquidation, reorganization, moratorium, labor, tax and other laws of general application relating to or affecting the rights of creditors generally; 
  
 (ii) in any legal proceedings brought to the courts of Mexico for the
enforcement of any of the Loan Documents or any judgment related thereto obtained in a foreign jurisdiction against the Borrowers, a Mexican court would apply Mexican procedural law in such proceedings; 
  
 (iii) in the event that proceedings are brought in Mexico seeking performance
of any of the Borrowers’ obligations in Mexico pursuant to the Mexican Monetary Law (Ley Monetaria de los Estados Unidos Mexicanos, or the “Monetary Law”), any such Borrower may discharge its obligations by paying any sums due in currency other than Mexican currency, in Mexican currency at a rate of exchange
prevailing in Mexico on the date when payment is made; therefore, under the Monetary Law, Section 11.16 (Judgment) of the Credit and Security Agreement may not be enforceable under Mexican law; 
  
 (iv) in the event that any legal proceedings are brought in the courts of
Mexico, a Spanish translation (prepared by a court-approved translator) of the Loan Documents which are executed in the English language must be filed in such proceedings and would have to be approved by the court after the defendant had been given
an opportunity to be heard with respect to the accuracy of the translation, and proceedings would thereafter be based upon the translated documents and in case of foreign public documents will require legalization before the appropriate Mexican
consulate as provided for by Article 1248 of the Mexican Commerce Code (Código de Comercio); 
  
 (v) pursuant to the laws of Mexico, creditors for the expenses incurred for the management of the bankruptcy estate, creditors for the expenses incurred
to cover ordinary protection expenses incurred for the conservation, management, safety of the bankruptcy estate, expenses incurred in connection with any procedure, judicial or extrajudicial, for the benefit of the bankruptcy estate, and the fees
of the visitador (visitor), conciliador (mediator) and sindico (receiver), labor claims, claims of tax authorities for unpaid taxes, social security quotas, workers’ housing fund quotas and retirement fund quotas are
preferred by statute and will have priority over claims of the Initial Lenders (or any permitted assignee thereof); 
  
 (vi) with respect to provisions contained in the Loan Documents in connection with service of process, it should be noted that service of process by mail
does not constitute personal service of process under Mexican law and, since such service is considered to be a basic procedural requirement, if for purposes of proceedings outside Mexico service of process is made by mail, a final judgment based on
such process would not be enforced by the courts of Mexico; 
  
 (vii) we note that the obligation to pay interest on interest may be unenforceable under Mexican law; 
  

 5 

 (viii) covenants of the Borrowers which purport to bind it on matters reserved by law to shareholders, or
which purport to bind shareholders to vote or refrain from voting their shares issued by the Borrowers or its subsidiaries, are not enforceable through specific performance, but may result in an acceleration of amounts payable under the Loan
Documents; 
  
 (ix) provisions of the Loan Documents granting
discretionary authority to the Administrative Agent or the Initial Lenders, as the case may be, cannot be exercised in a manner inconsistent with relevant facts nor defeat any requirements from a competent authority to produce satisfactory evidence
as to the basis of any determination; in addition, under Mexican law, each of the Borrowers will have the right to contest in court any notice or certificate of the Administrative Agent or the Initial Lenders purporting to be conclusive and binding;

  
 (x) any provision in any Loan Document to the effect that
invalidity and illegality of any part thereof will not invalidate the remaining obligations of such Loan Document may be unenforceable in Mexico to the extent that such provision constitutes an essential element of such Loan Document; 
  
 (xi) the taking of possession, entry, removal, sale, transfer or other
disposition of property or similar action in Mexico pursuant to the Loan Documents may not be made in Mexico without judicial intervention after the defendant is given the right to be heard and defeated in court; 
  
 (xii) claims may become barred under statutes of limitation or may become
subject to defenses or set-off or counter claim; 
  
 (xiii) in any
suit brought before Mexican courts, such courts may apply Mexican law on statutes of limitations (prescriptión); we express no opinion as to the enforceability in Mexico of a foreign judgment deriving from a lawsuit initiated after the
applicable Mexican statute of limitations period has elapsed; 
  
 (xiv) we note that procedural rights cannot be validly waived under Mexican law; 
  
 (xv) a Mexican court may stay proceedings held in such court if concurrent proceedings are being held elsewhere; 
  
 (xvi) we express no opinion as to the irrevocability of the powers-of-attorney granted by each of the Borrowers to the Process Agent; and 
  
 (xvii) we make no comment with regard to any representations made by the
Mexican parties in any of the Loan Documents referred to above or otherwise. 
  
 We express no opinion as to any laws other than the federal laws of Mexico currently in effect. We assume no responsibility to advise you of any changes to our opinion subsequent to the date hereof. Insofar as the
opinions set forth above are governed by New York law, we have relied, without making any independent investigation with respect thereto, and with your 

  

 6 

 
consent, solely on the opinion of Shearman & Sterling, special U.S. counsel to the Administrative Agent, dated the date hereof. To the extent such
opinion contains assumptions and qualifications, this opinion shall be subject to such assumptions and qualifications. 
  
 This opinion is addressed to you solely for your benefit in connection with the Loan Documents. This opinion may also be delivered to Shearman &
Sterling, U.S. counsel to the Administrative Agent, who may rely on this opinion to the same extent as if such opinion were addressed to them. It is not to be transmitted to anyone else no is it to be relied upon by anyone else or for any other
purpose or quoted or referred to in any public document or filed with anyone without our express consent.

 Annex A 
 Assigned Agreement 
  

 BATTERY SUPPLY AGREEMENT 
  
 THIS AGREEMENT is made effective as of the 1st day of February, 2002
(“Effective Date”) and is between (1) Enertec Mexico S. de R.L. de C.V., a Sociedad de Responsabilidad Limitada organized under the laws of Mexico having its principal place of business at Monterrey, Mexico (“Supplier”) and (2)
Johnson Controls Battery Group, Inc., having its principal place of business at 5757 North Green Bay Avenue, P.O. Box 591, Milwaukee, Wl 53201 (“Purchaser”). 
  
 WHEREAS, the parties entered into a Battery Supply Agreement dated November 30, 1998 for the supply of automotive batteries
by Supplier to Purchaser. 
  
 WHEREAS, the changing business of
the parties has necessitated the negotiation of a new Supply Agreement that accurately reflects and governs the supply of batteries between the parties. 
  
 NOW THEREFORE, in consideration of the foregoing, Supplier and Purchaser agree as follows: 
  

	1.	DEFINITIONS 

  

	 	1.1	“Business Day” shall have the same definition as set forth in the Operating Agreement. 

  

	 	1.2	“Products” shall mean the automotive, marine, lawn and garden and commercial battery products listed in Exhibit A. 

  

	 	1.3	“Operating Agreement” shall mean the Limited Liability Company Agreement of GES Mexico, L.L.C. between Global Energy Systems, S.A. de C.V. and Enermex, S.A. de C.V. dated
November 30,1998. 

  

	 	1.4	“Specifications” shall mean the specifications for each Product as provided by Purchaser under separate cover. 

  

	 	1.5	“1998 Agreement” shall mean the Supply Agreement dated November 30, 1998 by and between Enertec Mexico S. de R.L. de C.V. and Johnson Controls Battery Group, Inc.

  

	2.	TERMINATION OF 1998 AGREEMENT 

  
 The parties hereby agree to terminate the 1998 Agreement effective as of February 1, 2002. 
  

	3.	APPOINTMENTS AND SCOPE 

  
 3.1 Supplier hereby accepts responsibility to supply and deliver Product to Purchaser in accordance with the Specifications and this Agreement.

  

 3.2 Supplier shall deliver to Purchaser, or to destinations specified by Purchaser, only Products which
conform in all material respects to the Specifications. 
  

	4.	QUALITY OF PRODUCTS 

  
 4.1 The quality, safety and performance of the Products are critical to the success of the relationship described in this Agreement. 
  
 4.2 Each Product manufactured by Supplier shall be, in every material
respect, substantially identical to a sample or prototype that shall be first submitted to and approved in writing by Purchaser, and shall in no event be of lesser quality or performance than such sample. In producing the Products, Supplier shall
not make any change from the sample or prototype, including any change to its quality, appearance, labeling, instructions, directions or packaging, unless prior written approval of such change is given by Purchaser. 
  
 4.3 Purchaser may at any time notify Supplier in writing of any additional
changes to the then current Specifications relating to any Product which, if not objected to within fifteen (15) days of Purchaser’s notice, shall be deemed to be part of the Specifications. If Supplier determines that the proposed change
constitutes a substantial change and objects in writing within such fifteen (15) day period, the parties shall use reasonable efforts to agree when the proposed change shall become a Specification. If the parties cannot resolve their differences
within thirty (30) days of Supplier’s objection, Purchaser or Supplier shall have the right to remove the Product in question from this Agreement. 
  
 4.4 Purchaser may, at its sole expense, reasonably designate an inspection service, laboratory or other representative (the “Inspector”) to
inspect, analyze or conduct tests on any Product, sample or prototype to determine conformity with the Specifications. 
  
 4.5 With respect to any Product that Purchaser or the Inspector has not previously qualified, upon Purchaser’s or the Inspector’s reasonable
request, Supplier shall send up to six (6) sample batteries to Purchaser or to any location designated by Purchaser or the Inspector to conduct commercially reasonable tests. Supplier shall also, upon reasonable notice, make such Products available
for inspection, analysis and testing by Purchaser or the Inspector at Supplier’s own premises. 
  
 4.6 The Inspector may adopt and notify the Supplier of tolerances, standards or additional Specifications for any Product. Any such notice provided
pursuant to Section 4.5 shall be deemed a notice from Purchaser of additional Specifications under Section 4.3 above. 
  
 4.7 As soon as reasonably practical after the date hereof, Purchaser and Supplier shall develop a quality control plan for each customer to whom Purchaser
sells Products. Purchaser and the Inspector shall have the right, at their sole expense, to request that Supplier perform a commercially reasonable number and type of tests in accordance with the applicable quality control plan in the course of the
manufacture of the Products or prior to shipment, and Supplier shall perform such tests promptly and notify Purchaser of the results.

	5.	LABELLING AND PACKAGING 

  
 5.1 Supplier shall produce, mark, label and package each Product with labels, designs, color schemes, serial and code numbers, logos and other markings in
such manner and language as is instructed or approved in writing by Purchaser. Such markings shall be deemed to be included as part of the Specifications and shall be subject to Section 4.3. 
  
 5.2 Purchaser shall not be responsible for labels or packaging ordered by
Supplier for the Products in a quantity that exceeds forty-five (45) days of Purchaser’s forecasted requirements; however, the parties may agree in writing that Purchaser’s inventory responsibility associated with a specific Product may be
greater. 
  
 5.3 Supplier is prohibited from using any labels or
packaging for any purpose other than those established in this Agreement. 
  
 5.4 If a modification is made to any labels or packaging because of legal, regulatory or governmental requirements, or because of a decision by Purchaser, or in case of a termination as provided in Section 11, below,
Supplier shall promptly notify Purchaser of its existing inventory of the subject labels and packaging. Thereupon, Purchaser at its option shall either: 
  
 (a) authorize Supplier to utilize the preexisting labels and packaging on Products sold to Purchaser (if permitted by law); or 
  
 (b) repurchase Supplier’s stock of labels or packaging up to the
quantity stated in Section 5.2 above at Supplier’s cost; or 
  
 (c) adopt a combination of (a) and (b) above. 
  

	6.	ORDERS, SALES AND FORECASTS 

  
 6.1 Within three (3) Business Days of the first day of each calendar month, Purchaser will provide Supplier a twelve (12) month forecast of
Purchaser’s anticipated orders for Products. Supplier agrees that such forecast shall not constitute a binding contract. 
  
 6.2 All sales of the Products shall be between Supplier as seller and Purchaser as buyer. Product shall be ready to be shipped to Purchaser within
fourteen (14) Business Days of an order. In the event that Purchaser does not require availability within fourteen (14) Business Days, Purchaser shall specify its required delivery date, but such date shall not exceed thirty (30) days from the
originally scheduled date. Supplier shall continue to review the order processing in an effort to reduce the processing lead time. Supplier agrees that time is of the essence of its obligations under this Agreement. If Supplier fails to deliver the
Products within the timeframe provided herein, Purchaser reserves the right, without any liability hereunder to Purchaser, to terminate any order covering such Products, and to purchase Products from an alternative source, at Supplier’s
expense. 
  
 6.3 Purchaser may place preliminary orders by
facsimile or by written notice. Within five (5) Business Days from the receipt of each order, Supplier shall confirm or reject the order by written notice. Upon receiving Supplier’s confirmation, Purchaser will issue a formal written

  

 3 

 
purchase order. Supplier shall be under no obligation to supply Products to Purchaser until Supplier receives the formal written purchase order. 

 
 6.4 Supplier’s acceptance of Purchaser’s order is subject to all
of the terms and conditions included in this Agreement, all of which Purchaser accepts as superseding any terms or conditions on Purchaser’s order form or Supplier’s acknowledgement form, if any. 
  
 6.5 Purchaser may at any time cancel any shipment if delivery is not made by
the “Cancel Date” shown on the face of its purchase order, other than due to actions taken by Purchaser or force majeure, without cost or further obligation to Purchaser. 
  
 6.6 Purchaser’s final purchase order may state a delivery date. This delivery date may not be changed, unless otherwise
agreed in writing by Purchaser. Purchaser may change the delivery date by giving notice of the change to Supplier at least three (3) Business Days prior to shipment. 
  
 6.7 The targeted order fill rate is 98%. Supplier shall perform hereunder consistent with a 95% percent order fill rate;
however, an exception to this requirement is permitted to the extent the formal purchase order for Product differs from the Product forecast. In such case, the 95% order fill rate may vary plus or minus 5% from the Product forecast. For example, if
Purchaser forecasts it needs 100 batteries, but issues a formal purchase order for 120 batteries, then Supplier shall only be obligated to provide 99.75 batteries (95% of 105 batteries). 
  

	7.	PRICES, PAYMENT AND INCENTIVES 

  
 7.1 The prices applicable to each sale of Product under this Agreement, including both “wet” and “DUF” Product, will be the prices set
forth in Exhibit A, or such other prices as may be mutually agreed upon in writing by Purchaser and Supplier. Other than a quarterly lead price adjustment described below, the prices for the Product are firm through December 31, 2002. Thereafter,
and in no event less than annually, the parties shall review the pricing and make any necessary adjustments to reflect changes in the parties’ costs, including adjustments for currency and inflation, or changes to Product mix.

  
 7.2 The parties acknowledge that this Agreement reflects a
significant adjustment to the scope of the supply relationship and that the pricing reflected in this Agreement is based upon the parties’ best efforts to project future results. Further, the parties agree that the pricing for Calendar Year
2002 was set at a level designed to maintain both parties’ historical profit performance. Accordingly, on or before December 12, 2002, the parties agree to retrospectively review the pricing used for Calendar Year 2002, and to the extent the
pricing has resulted in a negative shift in the level of profitability of either party, then the parties agree that a one-time reconciliation payment or credit will be issued to the party whose profitability was negatively impacted by the pricing.
If a reconciliation payment or credit is due, then the parties agree that such payment or credit will be issued by no later than February 1, 2003. 
  
 7.3 The market price of primary lead used in the billing price is based on the average London Metals Exchange (LME) ($.2181/lb). To the extent
there are changes to the market price of lead, the billing price will not change; however, the parties agree to separately reconcile any lead price adjustments using the quarterly average of the monthly average cost of primary lead as set forth in
the LME. For purposes of calculating the lead price adjustment, the parties agree to use the 

  

 4 

 
price differential between the average market price of the LME versus the $.2181/lb (used in the billing price) multiplied by each Product’s lead
specification weight as set forth on Exhibit A. For purposes herein, “specification weight” shall mean the lead content of each Product, including oxide, identified in the engineering bill of material. 
  
 The lead price reconciliation will be settled and paid quarterly based on the following
schedule: 
  

			
	 Average LME

	  	 Effective Pricing Period

	 Sept. – Nov.
	  	Jan. – March
	 Dec. – Feb.
	  	April – June
	 March – May
	  	July – Sept.
	 June – Aug.
	  	Oct. – Dec.

  
 7.4 The prices include
(and Supplier shall be responsible for) all costs of the Product. Supplier shall be responsible for all charges, levies, duties and taxes applicable to the production, shipment or sale of the Product, and all costs of freight and delivery up to and
through the point of border entry in the U.S. as designated by Purchaser (e.g. Laredo, TX or El Paso, TX), including any import costs, duties or taxes incurred while importing the Product into the U.S.; provided, that throughout the term of
the Agreement, to the extent there are increases to the import costs, duties or taxes, the parties agree to review the pricing for any necessary adjustments. 
  
 7.5 The parties may agree to deliver the Product in a manner or to a destination other than as described in Section 7.4 above. If Purchaser requests
Supplier to ship the Product to a destination other than a point of border entry (e.g. distribution center, plant, or customer location), then Supplier shall be responsible for any charges, levies, duties and taxes, but Supplier shall only be
responsible for the freight costs up to and through the point of border entry. Purchaser shall be responsible for all other freight costs incurred from the point of border entry to the ultimate delivery destination. In the event the parties agree
that Purchaser, rather than Supplier, will arrange carriage, the cost of freight incurred by Purchaser to the point of border entry into the U.S. shall be charged back to Supplier. The parties agree that the reconciliation process for such costs
incurred under this Section 7.5 will be billed through the invoicing procedures described herein. 
  
 7.6 Payments shall be made sixty (60) days after the date of shipment from Supplier’s plant. Payments will be made twice each month according to
Purchaser’s payment schedules, which Purchaser will provide to Supplier by October 15th of each year of this
Agreement. If any of the Products are lost, damaged or fail to arrive at such designated address. Purchaser shall not be obligated to pay for such merchandise, except for any amounts it recovers from the carrier or an insurer. 
  
 7.7 Each sale to Purchaser shall be for resale unless otherwise indicated on
the face of the purchase order for that sale. 
  
 7.8 To the
extent the parties desire to add new Products to this Agreement, Exhibit A shall be supplemented accordingly and the pricing for any such new Product shall be mutually agreed upon by the parties and calculated based upon the pricing of comparable
Products with similar characteristics (i.e. Group Size, wet vs. DUF, CCA/RC ratings). 
  

 5 

	8.	VOLUME 

  
 The volume requirement for Product to be supplied under this Agreement during calendar year 2002 is approximately 10.5 million units of Product less the Enertec’ shipments of Product to GES America, L.LC.
Supplier acknowledges, however, that Purchaser’s requirements for Products are principally determined by customers’ demand for Products and that Purchaser has no control or influence over customer decisions. In the event there are
significant changes to Purchaser’s sales volume requirements, either increases or decreases, Supplier acknowledges and agrees that such changes may impact the supply requirements under this Agreement. Purchaser agrees to provide Supplier
written notice of its anticipated annual volume requirements for subsequent years by September 30th of each year of
this Agreement. 
  

	9.	DELIVERY, ACCEPTANCE, REJECTION 

  
 9.1 As of the Effective Date of this Agreement, the delivery point for each sale shall be designated by the Purchaser and may be any of the following: (i)
the point of border entry into the U.S.; (ii) a Johnson Controls distribution center, plant or customer location as identified by Purchaser; or (iii) if the parties have agreed in writing that Purchaser will arrange carriage for that particular
shipment, the place where the Purchaser’s carrier takes possession of the Products. All freight lane rates shall be mutually agreed upon and will be based upon optimized routes and entry points in order to achieve the lowest costs. 

 
 9.2 Supplier shall (i) send to Purchaser a separate invoice, bill of
lading and packing list for each Purchaser purchase order and (ii) mark all invoices, bills of lading, packing lists and packages to show legibly the Purchaser purchase order number to which that shipment relates. 
  
 9.3 Supplier shall notify Purchaser Immediately if any part of any order
cannot be delivered to the delivery point by the “Cancel Date” on the face of any purchase order. Purchaser shall be obligated to accept all back orders and late shipments authorized by Purchaser. 
  
 9.4 No Product shall be considered to have been received by Purchaser until;
(i) if to a point of border entry into the U.S., when a custom agent has signed a bill of lading or other shipping document acknowledging actual receipt of the specific Product; (ii) if Purchaser arranges carriage, when the Product has been fully
loaded aboard the truck, rail car or other vehicle of the carrier, or (iii) if to a destination other than a point of border entry, then when an authorized representative of the designated location has signed a bill of lading. 
  
 9.5 Risk and damage for loss of goods shall pass from Supplier to Purchaser
when the Product has been received by the Purchaser pursuant to Section 9.4. 
  
 9.6 Purchaser shall send any Products that are non-conforming, shipped contrary to Purchaser’s instructions, this Agreement, or to the applicable purchase order to the destination designated by Supplier (at
Supplier’s expense). As part of Purchaser’s good faith rejection, Purchaser must allow Supplier the opportunity to examine the alleged defective Products at Supplier’s expense prior to returning them to Supplier. Supplier should
advise Purchaser of the results of this analysis within ten (10) Business Days from its receipt of data or the Product used by Supplier for determining its results. 
  

 6 

 9.7 The exercise of any right or remedy provided herein shall be without prejudice to any other right or
remedy available to either party. 
  
 9.8 Product shall be
manufactured with poly components manufactured by Purchaser and purchased by Supplier or with poly cómponents manufactured by Supplier so long as they have been approved by Purchaser. 
  

	10.	WARRANTY AND INDEMNITY 

  
 10.1 The Products supplied under this Agreement are provided at a discounted price in lieu of warranty, and the pricing provided in Exhibit A has been
provided to reflect such program. Except to the extent of a manufacturing defect common to an entire lot, Supplier disclaims and makes no warranties regarding the Products, express or implied, and hereby expressly excludes any warranties as to the
merchantability or fitness for any particular purpose or use. For purpose of this Section 10.1, “an entire lot” shall mean a group of batteries with a manufacturing code indicating an identical date and production shift. In the event of a
defect common to an entire lot Supplier shall be responsible for the full cost of any of Purchaser’s direct expenses incurred with such manufacturing defect occurrence. 
  
 10.2 PRODUCT LIABILITY: Provided that Purchaser promptly notifies Supplier in writing pursuant to the notice provisions of
this Agreement, Supplier shall defend, indemnify, save and hold Purchaser harmless from and against all claims, damages, suits, losses, fines, costs and expenses, including reasonable attorney’s fees, arising out of the negligence or fault of
the Supplier and Involving the Product which results in (a) the death of or injury to any person, or (b) any damage to personal property of any kind sustained by any person, firm or corporation. 
  
 10.3 The warranties, Indemnities and obligations of Supplier under this
Agreement shall not be affected, limited, or in any way altered by Purchaser’s extension of express or implied warranties to its customers. 
  

	11.	TERM AND TERMINATION 

  
 11.1 The term of this Agreement shall begin on February 1, 2002 and expire on December 31, 2002, unless terminated sooner as provided below; however, this
Agreement will automatically renew for additional one year terms unless either party provides sixty (60) days written notice prior to December 31st of each year.
