opinion (regarding violation of Applicable Agreements) will have to be qualified if Section 4.2(F)
of the Loan Agreement contains a restriction on the ability of the Borrower to pay distributions.
The Guarantor’s indentures contain a covenant that might be violated by such a restriction.] (C)
resulted, results or will result in the creation of any security interest in, or lien upon, any of
the property or assets of the Borrower pursuant to any Applicable Agreement, (D) resulted, results
or will result in any violation of (i) applicable laws of the State of New York, (ii) applicable
laws of the State of Texas, (iii) applicable laws of the United States of America, or (iv) the
Delaware Limited Liability Company Act, or (E) resulted, results or will result in the
contravention of any Applicable Order.



6. No Governmental Approval, which has not been obtained or taken and is not in full force and
effect, is required to authorize, or is required for the execution and delivery by the Borrower of
the Transaction Documents, or the incurrence or performance of its obligations thereunder, or the
enforceability of the Transaction Documents against the Borrower. As used in this paragraph,
“Governmental Approval” means any consent, approval, license, authorization or validation of, or
filing, recording or registration with, any executive, legislative, judicial, administrative or
regulatory body of the State of New York, the State of Texas, the State of Delaware or the United
States of America, pursuant to (i) applicable laws of the State of New York, (ii) applicable laws
of the State of Texas, (iii) applicable laws of the United States of America, or (iv) the Delaware
Limited Liability Company Act.



7. If and to the extent that, at the time of its execution and delivery of the Loan Agreement,
the Borrower would otherwise have been entitled under the United States Foreign Sovereign
Immunities Act of 1976, as amended (the “USFSIA”) to any immunity on the grounds of sovereignty in
respect of its obligations under the Loan Agreement (a matter as to which we express no opinion),
then the provisions of the Loan Agreement providing for a waiver by the Borrower of such immunity
would constitute an effective waiver under the USFSIA of such immunity. We wish to point out,
however, that (a) we express no opinion as to the effect of said waiver provisions if and to the
extent that the Borrower acquired immunity on the grounds of sovereignty after its execution and
delivery of the Loan Agreement, and (b) any waiver of sovereign immunity (i) is subject to the
limitations imposed by the USFSIA, and (ii) will be effective to permit attachment of or execution
upon only such property of the Borrower, and only under such circumstances, as may be permitted by
USFSIA.



We express no opinion as to the laws of any jurisdiction other than (i) applicable laws of the
State of New York, (ii) applicable laws of the State of Texas, (iii) applicable laws of the United
States of America, (iv) certain other specified laws of the United States of America to the extent
referred to specifically herein, and (v) the Delaware Limited Liability Company Act. References
herein to “applicable laws” mean those laws, rules and regulations that, in our experience, are
normally applicable to transactions of the type contemplated by the Transaction Documents, without
our having made any special investigation as to the applicability of any specific law, rule or
regulation, and that are not the subject of a specific opinion herein referring expressly to a
particular law or laws; provided, however, that such references (including without limitation those
appearing in paragraphs 5 and 6 above) do not include any municipal or other local laws, rules or
regulations, or any antifraud, environmental, labor, securities, tax, insurance or antitrust, laws,
rules or regulations.



Our opinions expressed herein are subject to the following additional assumptions and
qualifications:



(i) The opinion set forth in paragraph 1 above as to the valid existence and good standing of
the Borrower is based solely upon our review of certificates and other communications from the
appropriate public officials.


 


3









 





(ii) In rendering the opinions set forth in paragraph 5 above regarding Applicable Agreements,
we do not express any opinion, however, as to whether the execution or delivery by the Borrower of
the Transaction Documents, or the incurrence or performance by the Borrower of its obligations
thereunder, will constitute a violation of, or a default under or as a result of, any covenant,
restriction or provision with respect to any financial ratio or test or any aspect of the financial
condition or results of operation of the Borrower.




(iii) Our opinion in paragraph 4 above may be:




(1) limited by applicable bankruptcy, insolvency, reorganization, moratorium,
fraudulent conveyance or transfer or other similar laws relating to or affecting the rights
of creditors generally; and




(2) subject to the application of general principles of equity (regardless of whether
considered in a proceeding in equity or at law), including, without limitation, the possible
unavailability of specific performance, injunctive relief or any other equitable remedy and
concepts of materiality, reasonableness, good faith and fair dealing.



(iv) We wish to point out that the obligations of the Borrower, and the rights and remedies of
the Lender, under the Transaction Documents, may be subject to possible limitations upon the
exercise of remedial or procedural provisions contained in the Transaction Documents; provided,
that such limitations do not, in our opinion (but subject to the other comments and qualifications
set forth in this opinion letter), make the remedies and procedures that will be afforded to the
Lender inadequate for the practical realization of the substantive benefits purported to be
provided to the Lender by the Transaction Documents.



(v) Our opinion in paragraph 4 insofar as it pertains to the choice of law provision of the
Loan Agreement purporting to select New York law as governing, or any provision that purports to
constitute a submission to the jurisdiction of one or more specified courts or to waive the right
to object to any court as an inconvenient forum, is rendered solely in reliance upon New York
General Obligations Law §§ 5-1401 and 5-1402, and New York Civil Practice Law and Rules 327(b), and
is expressly conditioned upon the assumption that the legality, validity, binding effect and
enforceability of said provisions will be determined by a court of the State of New York or (in the
case of provisions purporting to select New York law as governing) a United States Federal court
sitting in New York and applying New York choice of law rules, including said § 5-1401 (in which
regard we note that Section 7.8 of the Loan Agreement purports to deny effect to the State of New
York’s “principles of conflict of laws” and we express no opinion as to the effect, if any, upon
any opinion herein expressed of such provisions). We express no opinion as to any such provision
if such legality, validity, binding effect or enforceability is determined by any other court, and
we call your attention to the decision of the United States District Court for the Southern
District of New York in Lehman Brothers Commercial Corp. v. Minmetals Int’l Non-Ferrous Metals
Trading Co., 179 F. Supp. 2d 119 (S.D.N.Y. 2000), which, among other things, contains dicta
relating to possible constitutional limitations upon said Section 5-1401 in both domestic and
international transactions. We express no opinion as to any such constitutional limitations upon
said Sections 5-1401 and 5-1402 or their effect, if any, upon any opinion herein expressed.




(vi) We express no opinion as to the validity, enforceability or effect of any provisions:




(1) purporting to establish evidentiary standards or limitations periods for suits or
proceedings to enforce such documents or otherwise, to establish certain determinations
(including determinations of contracting parties and judgments of courts) as conclusive or
conclusive absent manifest error, to commit the same to the discretion of any Person or
permit any Person to act in its sole judgment or to waive rights to notice;


 


4









 






(2) providing that the assertion or employment of any right or remedy shall not prevent
the concurrent assertion or employment of any other right or remedy, or that each and every
remedy shall be cumulative and in addition to every other remedy or that any delay or
omission to exercise any right or remedy shall not impair any other right or remedy or
constitute a waiver thereof;




(3) relating to severability or separability;




(4) purporting to limit the liability of, or to exculpate, any Person, including
without limitation any provision that purports to waive liability for violation of
securities laws;




(5) purporting to waive damages or rights which under applicable law are not subject to
waiver;




(6) that constitute an agreement to agree in the future on any matter;




(7) that relate to indemnification, contribution or reimbursement obligations to the
extent any such provisions (i) would purport to require any Person to provide
indemnification, contribution or reimbursement in respect of the negligence, recklessness,
willful misconduct or unlawful or wrongful behavior of any Person, (ii) violate any law,
rule or regulation (including any federal or state securities law, rule or regulation) or
(iii) are determined to be contrary to public policy;




(8) purporting to establish any obligation of any party as absolute or unconditional
regardless of the occurrence or non-occurrence or existence or non-existence of any event or
other state of facts;




(9) purporting to obligate any party to conform to a standard that may not be
objectively determinable or employing items that are vague or have no commonly accepted
meaning in the context in which used;




(10) purporting to require that all amendments, waivers and terminations be in writing
or the disregard of any course of dealing or usage of trade;




(11) relating to consent to jurisdiction insofar as such provisions purport to confer
subject matter jurisdiction upon any court that does not have such jurisdiction, whether in
respect of bringing suit, enforcement of judgments or otherwise;




(12) relating to rights of setoff or counterclaim; or




(13) relating to powers of attorney or attorneys in fact.



We also express no opinion as to the validity, enforceability or effect of any schedules, exhibits,
annexes, appendixes or other attachments, other than the Schedule, in each case, attached to or
referenced in the Loan Agreement.


 


5









 





(vii) In making our examination of executed documents, we have assumed (except to the extent
that we expressly opine above) (1) the valid existence and good standing of each of the parties
thereto, (2) that such parties had the power and authority, corporate, partnership, limited
liability company or other, to enter into and to incur and perform all their obligations
thereunder, (3) the due authorization by all requisite action, corporate, partnership, limited
liability company or other, and the due execution and delivery by such parties of such documents
and (4) to the extent such documents purport to constitute agreements, that each of such documents
constitutes the legal, valid and binding obligation of each party thereto, enforceable against such
party in accordance with its terms. In this paragraph (vii), all references to parties to
documents shall be deemed to mean and include each of such parties, and each other person (if any)
directly or indirectly acting on its behalf.



(viii) Except to the extent that we expressly opine above, we have assumed that the execution
and delivery of the Transaction Documents, and the incurrence and performance of the obligations
thereunder of the parties thereto do not and will not contravene, breach, violate or constitute a
default under (with the giving of notice, the passage of time or otherwise) (a) the certificate or
articles of incorporation, certificate of formation, articles of organization, certificate of
limited partnership, charter, bylaws, limited liability company agreement, regulations, limited
partnership agreement or similar organic document of any such party, (b) any contract, indenture,
mortgage, loan agreement, note, lease or other agreement or instrument, (c) any statute, law, rule,
or regulation, (d) any judicial or administrative order or decree of any governmental authority, or
(e) any consent, approval, license, authorization or validation of, or filing, recording or
registration with, any governmental authority, in each case, to which any party to the Transaction
Documents or any of its subsidiaries or any of their respective properties may be subject, or by
which any of them may be bound or affected. Further, we have assumed the compliance by each such
party, other than the Borrower, with all laws, rules and regulations applicable to it, as well as
the compliance by the Borrower, and each other person (if any) directly or indirectly acting on its
behalf, with all laws, rules and regulations that may be applicable to it by virtue of the
particular nature of the business conducted by it or any goods or services produced or rendered by
it or property owned, operated or leased by it, or any other facts pertaining specifically to it.
In this paragraph (viii), all references to parties to the Transaction Documents, other than the
first such reference, shall be deemed to mean and include each of such parties, and each other
person (if any) directly or indirectly acting on its behalf.



(ix) We express no opinion as to the effect of the laws of any jurisdiction in which the
Lender is located (other than the State of New York) that limit the interest, fees or other charges
such Lender may impose for the loan or use of money or other credit.



(x) We point out that the submissions to the jurisdiction of any Federal or State court
sitting in the State of New York contained in the Transaction Documents cannot supersede a federal
court’s discretion in determining whether to transfer an action to another court.



(xi) Except to the extent that we expressly opine above, we have assumed that no
authorization, consent or other approval of, notice to or registration, recording or filing with
any court, governmental authority or regulatory body is required to authorize, or is required in
connection with the transactions contemplated by the Transaction Documents, the execution or
delivery thereof by or on behalf of any party thereto or the incurrence or performance by any of
the parties thereto of its obligations thereunder.



This opinion is being furnished only to you in connection with the consummation of the transactions
under the Loan Agreement occurring today and is solely for your benefit and is not to be used,
circulated, quoted or otherwise referred to for any other purpose or relied upon by any other
Person, without our express written permission. The opinions expressed herein are as of the date
hereof only and are based on laws, orders, contract terms and provisions, and facts as of such
date, and we disclaim any obligation to
update this opinion letter after such date or to advise you of changes of facts stated or assumed
herein or any subsequent changes in law.



Very truly yours,

EXHIBIT D




FORM OF GUARANTY




GUARANTY (this “Agreement”) made and entered into on this
 _____ 
day of
 _____, 200_____ 

by ALLIS-CHALMERS ENERGY INC., a corporation organized and existing under the laws of Texas with
its principal place of business located at 5075 Westheimer, Suite 890, Houston, Texas 77056
(hereinafter, referred to as “Guarantor”), in favor of CATERPILLAR FINANCIAL SERVICES CORPORATION,
a Delaware corporation with its principal place of business located at 2120 West End Avenue,
Nashville, Tennessee 37203 (hereinafter, referred to as “Cat Financial”), guaranteeing the
Indebtedness of ALLIS-CHALMERS DRILLING LLC, a limited liability company organized and existing
under the laws of
 _____ 
(hereinafter referred to as “Borrower”).



WITNESSETH:




FOR VALUE RECEIVED, and in consideration of and for credit and financial accommodations
extended to or for the account of Borrower, Guarantor agrees as follows:



SECTION 1. Guaranty of Borrower’s Indebtedness. Guarantor hereby absolutely and
unconditionally agrees to, and by these presents does hereby, guarantee the prompt and punctual
payment, performance and satisfaction of Borrower’s obligations under that certain Master Loan and
Security Agreement dated
 _____, 200_____, made by Borrower in favor of Cat Financial
(the “Loan Agreement”), and any and all schedules, exhibits, and amendments thereto and/or
renewals, extensions and/or refinancings thereof, in Loan Agreement payments, principal, interest,
costs, indemnification obligations and attorneys’ fees and under all other related documents (with
all of Borrower’s indebtedness and/or obligations under the Loan Agreement and all related
documents being hereinafter individually and collectively referred to under this Agreement as
Borrower’s “Indebtedness”). THIS GUARANTY SHALL BE CONTINUING, ABSOLUTE, AND UNCONDITIONAL.



SECTION 2. Joint and Several Liability. Guarantor further agrees that its
obligations and liabilities for the prompt and punctual payment, performance and satisfaction of
Borrower’s Indebtedness shall be on a “joint and several” basis along with Borrower to the same
degree and extent as if Guarantor had been and/or will be a co-Borrower, co-principal obligor
and/or co-maker of Borrower’s Indebtedness. In the event that there is more than one guarantor
under this Agreement, or in the event that there are other guarantors, endorsers or sureties of all
or any portion of Borrower’s Indebtedness, Guarantor’s obligations and liabilities hereunder shall
be on a “joint and several” basis along with such other guarantor or guarantors, endorsers and/or
sureties.



SECTION 3. Duration; Cancellation of Agreement. This Agreement and Guarantor’s
obligations and liabilities hereunder shall remain in full force and effect until such time as
Borrower’s Indebtedness shall be paid, performed and/or satisfied in full, in loan payments,
principal, interest, costs and attorneys’ fees (but subject to the automatic reinstatement
provisions set forth hereinbelow). Nothing under this Agreement or under any other agreement or
understanding by and between Guarantor and Cat Financial, shall in any way obligate, or be
construed to obligate, Cat Financial to agree to the subsequent termination or cancellation of
Guarantor’s obligations and liabilities hereunder as long as Borrower’s Indebtedness remains unpaid
and outstanding; it being fully understood and agreed by Guarantor that Cat Financial may, within
its sole and uncontrolled discretion and judgment, refuse to release Guarantor from any of its
obligations and liabilities under this Agreement for any reason whatsoever as long as Borrower’s
Indebtedness remains unpaid and outstanding.


 


2









 





SECTION 4. Default by Borrower. Should Borrower default under any of its
Indebtedness in
favor of Cat Financial, Guarantor unconditionally and absolutely agrees to pay the full, then
unpaid amount of Borrower’s Indebtedness including but not limited to loan payments, principal,
interest, costs and attorneys’ fees. Such payment or payments shall be made immediately following
demand by Cat Financial at Cat Financial’s offices indicated below in Section 14 of this Agreement.



SECTION 5. Waivers by Guarantor. Guarantor waives, for the benefit of Cat Financial:
(a) notice of the acceptance of this Agreement; (b) notice of the existence, creation or
incurrence of new and/or additional debt owing from Borrower to Cat Financial; (c) presentment,
protest and demand, and notice of protest, demand, nonpayment, nonperformance and dishonor of any
and all agreements, notes or other obligations signed, accepted, endorsed or assigned to or by Cat
Financial or agreed to between Borrower and Cat Financial; (d) notice of adverse change in
Borrower’s financial condition or any other fact which might materially increase the risk of
Guarantor; (e) any and all rights in and notices or demands relating to any Equipment, including
without limitation, all rights, notices, advertisements or demands relating, whether directly or
indirectly, to the foreclosure, sale or other disposition of any or all such Equipment or the
manner of such sale or other disposition; (f) any claim, right or remedy which Guarantor may now
have or hereafter acquire against the Borrower that arises hereunder and/or from the performance by
any other guarantor or guarantors, endorsers and/or sureties including, without limitation, any
claim, remedy or right of subrogation, reimbursement, exoneration, contribution, indemnification,
or participation in any claim, right or remedy of Cat Financial against the Borrower or any
security which Cat Financial now has or hereafter acquires with respect to the Borrower, whether or
not such claim, right or remedy arises in equity, under contract (express or implied), by statute,
under common law or otherwise; (g) notice of any default by Borrower or any other person obligated
in any manner for all or any portion of Borrower’s Indebtedness and notice of any legal proceedings
against such parties; (h) any right of contribution from any other guarantor or guarantors,
endorsers and/or sureties; (i) notice and hearing as to any prejudgment remedies; (j) any defense
which is premised on an alleged lack of consideration of the obligation undertaken by Guarantor,
including without limitation, any defense to the enforcement of this Agreement based upon the
timing of execution of this Agreement and/or that the Agreement had been executed after the
execution date of any agreements evidencing the Indebtedness; (k) all exemptions and homestead
laws; (l) any other demands and notices required by law; (m) all setoffs and counterclaims against
Cat Financial and/or Borrower; (n) any defense based on the claim that Guarantor’s liabilities and
obligations exceed or are more burdensome than those of Borrower; (o) any defense which the
Borrower may assert or be able to assert on the underlying Indebtedness or which may be asserted by
Guarantor, including but not limited to (i) breach of warranty, (ii) fraud, (iii) statute of
frauds, (iv) infancy, (v) statute of limitations, (vi) lender liability, (vii) accord and
satisfaction, (viii) payment and/or (ix) usury.



SECTION 6. Guarantor’s Subordination of Rights to Cat Financial. In the event that
Guarantor should for any reason (i) advance or lend monies to Borrower for any reason whatsoever,
whether or not such funds are used by Borrower to make payment or payments under Borrower’s
Indebtedness, and/or (ii) make any payment for and on behalf of Borrower under Borrower’s
Indebtedness, and/or (iii) make any payment to Cat Financial in total or partial satisfaction of
Guarantor’s obligations and liabilities hereunder, Guarantor hereby agrees that any and all rights
that Guarantor may have or acquire to collect or to be reimbursed by Borrower (or by any guarantor,
endorser or surety of Borrower’s Indebtedness), whether Guarantor’s rights of collection or
reimbursement arise by way of subrogation to the rights of Cat Financial or otherwise, shall in all
respects be subordinate, inferior and junior to Cat Financial’s rights to collect and enforce
payment, performance and satisfaction of Borrower’s then remaining Indebtedness, until such time as
Borrower’s Indebtedness is fully paid and satisfied.



Guarantor further agrees to refrain from attempting to collect and/or enforce any of
Guarantor’s aforesaid rights against Borrower (or any other guarantor, surety or endorser of
Borrower’s Indebtedness), arising by way of subrogation or otherwise, until such time as Borrower’s
then remaining Indebtedness in
favor of Cat Financial is fully paid and satisfied, in principal, costs and attorneys’ fees.


 


3









 





In the event that Guarantor should for any reason whatsoever receive any payment or payments
from Borrower (or any other guarantor, surety or endorser of Borrower’s Indebtedness) on any such
amount or amounts that Borrower (or such a third party) may owe to Guarantor for any of the reasons
stated above, Guarantor agrees to accept such payment or payments for and on behalf of Cat
Financial, advising Borrower (or the third party payee) of such a fact, and Guarantor
unconditionally agrees to immediately deliver such funds to Cat Financial, with such funds being
held by Guarantor during any interim period, in trust for Cat Financial. In the event that
Guarantor should for any reason receive any such funds from Borrower (or any third party payee),
and Guarantor should deposit such funds in one or more of Guarantor’s deposit accounts, no matter
where located, Cat Financial shall have the right to attach any and all of Guarantor’s deposit
accounts in which such funds were deposited, whether or not such funds were commingled with other
monies of Guarantor, and whether or not such funds then remain on deposit in such an account or
accounts. To this end, Guarantor collaterally assigns and pledges to Cat Financial any and all of
Guarantor’s present and future rights, title and interest in and to all monies that Guarantor may
now and/or in the future maintain in deposit with banks, savings and loan associations and other
entities, in which Guarantor may at any time deposit any such funds that may be received from
Borrower (or any other guarantor, endorser or surety of Borrower’s Indebtedness) in favor of Cat
Financial.



SECTION 7. Actions by Cat Financial. Guarantor further agrees that Cat Financial
may, at its sole option, at any time, and from time to time, without the consent of or notice to
Guarantor, or any one of them, or to any other party, and without incurring any responsibility to
Guarantor or to any other party, and without impairing or releasing the obligations of Guarantor
under this Agreement:



(A) Discharge or release any party (including, but not limited to, Borrower or any
co-guarantor under this Agreement) who is or may be liable to Cat Financial for Borrower’s
Indebtedness;



(B) Sell, exchange, release, surrender, realize upon or otherwise deal with, in any manner and
in any order, any collateral directly or indirectly securing repayment of Borrower’s Indebtedness;



(C) With the mutual consent of Borrower or pursuant to the default terms of any agreement with
Borrower, change the manner, place or terms of payment, or change or extend the time of payment of
or renew, as often and for such periods as Cat Financial may determine, or alter Borrower’s
Indebtedness;




(D) Settle or compromise Borrower’s Indebtedness;



(E) Subordinate and/or agree to subordinate the payment of all or any part of Borrower’s
Indebtedness to the payment of any other present and/or future creditors of Borrower;



(F) Apply any payments made by Borrower or others and/or proceeds derived from cross-secured
collateral to other loans that Borrower may then owe to Cat Financial, whether Borrower’s
Indebtedness subject to this Agreement remains unpaid;



(G) Take or accept any other security or guaranty for any or all of Borrower’s Indebtedness;
and/or



(H) Enter into, deliver, modify, amend or waive compliance with, any instrument or arrangement
evidencing, securing or otherwise affecting, all or any part of Borrower’s Indebtedness.


 


4









 





In addition, no course of dealing between Cat Financial and Borrower (or any other guarantor,
surety or endorser of Borrower’s Indebtedness), nor any failure or delay on the part of Cat
Financial to exercise any of Cat Financial’s rights and remedies, or any other agreement or
agreements by and between Cat Financial and Borrower (or any other guarantor, surety or endorser)
shall have the effect of impairing or releasing Guarantor’s obligations and liabilities to Cat
Financial or of waiving any of Cat Financial’s rights and remedies. Any partial exercise of any
rights and remedies granted to Cat Financial shall furthermore not constitute a waiver of any of
Cat Financial’s other rights and remedies, it being Guarantor’s intent and agreement that Cat
Financial’s rights and remedies shall be cumulative in nature. Guarantor further agrees that,
should Borrower default under its Indebtedness, any waiver or forbearance on the part of Cat
Financial to pursue, the rights and remedies available to Cat Financial shall be binding upon Cat
Financial only to the extent that Cat Financial specifically agrees to such waiver or forbearance
in writing. A waiver or forbearance on the part of Cat Financial as to one event of default shall
not constitute a waiver or forbearance as to any other default.



SECTION 8. No Release of Guarantor. Subject to the cancellation provisions of
SECTION 3 hereof, Guarantor’s obligations and liabilities under this Agreement shall not be
released, impaired, reduced or otherwise affected by, and shall continue in full force and effect,
notwithstanding the occurrence of any event, including without limitation any one or more of the
following events:



(A) Death, insolvency, bankruptcy, arrangement, adjustment, composition, liquidation,
disability, dissolution or lack of authority (whether corporate, partnership or trust) of Borrower
(or any person acting on Borrower’s behalf), or any other guarantor, surety or endorser of
Borrower’s Indebtedness;



(B) Partial payment or payments of any amounts due and/or outstanding under Borrower’s
Indebtedness;



(C) Any payment by Borrower or any other party to Cat Financial that is held to constitute a
preferential transfer or a fraudulent conveyance under any applicable law, or for any reason, Cat
Financial is required to refund such payment or pay such amount to Borrower or to any other person;



(D) The unenforceability against Borrower of the Loan Agreement or any provisions thereof or
any documents related thereto;




(E) Any sale or assignment of the Loan Agreement; and/or



(F) Any failure of Cat Financial to notify Guarantor of the acceptance of this Agreement or of
the failure of Borrower to make any payment due by Borrower to Cat Financial.



This Agreement and Guarantor’s obligations and liabilities hereunder shall continue to be
effective, and/or shall automatically and retroactively be reinstated if a release or discharge has
occurred, as the case may be, if at any time any payment or part thereof to Cat Financial with
respect to Borrower’s Indebtedness is rescinded or must otherwise be restored by Cat Financial
pursuant to any insolvency, bankruptcy, reorganization, receivership, or any other debt relief
granted to Borrower or to any other party. In the event that Cat Financial must rescind or restore
any payment received by Cat Financial in satisfaction of Borrower’s Indebtedness, any prior release
or discharge from the terms of this Agreement given to Guarantor shall be without effect, and this
Agreement and Guarantor’s obligations and liabilities hereunder shall automatically be renewed or
reinstated and shall remain in full force and effect to the same degree and extent as if such a
release or discharge was never granted. It is the intention of Cat Financial and Guarantor that
Guarantor’s obligations and liabilities hereunder shall not be discharged except by Guarantor’s
full and complete performance of such obligations and liabilities and then only to the extent of
such performance and only in accordance with Section 3 hereof.

SECTION 9. Enforcement of Guarantor’s Obligations and Liabilities. Guarantor
understands, agrees and confirms that this is a guaranty of payment when due and not of collection.
Guarantor agrees that, should Cat Financial deem it necessary to file an appropriate collection
action to enforce Guarantor’s obligations and liabilities under this Agreement, Cat Financial may
commence such a civil action against Guarantor without the necessity of first (i) attempting to
collect Borrower’s Indebtedness from Borrower or from any other guarantor, surety or endorser,
whether through filing of suit or otherwise, (ii) attempting to exercise against any collateral
directly or indirectly securing repayment of Borrower’s Indebtedness, whether through the filing of
an appropriate foreclosure action or otherwise, or (iii) including Borrower or any other guarantor,
surety or endorser of Borrower’s Indebtedness as an additional party defendant in such a collection
action against Guarantor. In the event that Cat Financial should ever deem it necessary to refer
this Agreement to an attorney-at-law for the purpose of enforcing Guarantor’s obligations and
liabilities hereunder, or of protecting or preserving Cat Financial’s rights hereunder, Guarantor
(and each of them, on a joint, several and solidary basis) agrees to reimburse Cat Financial for
the reasonable fees of such an attorney. Guarantor additionally agrees that Cat Financial shall
not be liable for failure to use diligence in the collection of any of Borrower’s Indebtedness (or
any collateral security therefore), or in creating or preserving the liability of any person liable
on any such Indebtedness, or in creating, perfecting or preserving any security for any such
Indebtedness.



SECTION 10. Representations and Warranties by Guarantor. Guarantor represents and
warrants to Cat Financial that:



(A) The Guarantor has the lawful power, to conduct its business, to own its property and to
execute and deliver, and to perform all of its obligations hereunder.



(B) All necessary actions and consents required to be performed, obtained and/or satisfied
prior to the execution, delivery and performance of this Agreement have been performed, obtained
and satisfied in due and strict compliance with all applicable laws, including all necessary
corporate actions, consents, and authorizations. The execution, delivery and performance by the
Guarantor of its obligations hereunder does not and will not (i) require any additional
authorization, consent or approval by any governmental department, commission, board, bureau,
agency or instrumentality, domestic or foreign, (ii) violate any provision of any law, rule or
regulation or of any order, writ, award, judgment, ministerial decision, injunction or decree
presently in effect having applicability to the Guarantor, or (iii) result in a breach of or
constitute a default under any indenture or loan or credit agreement or any other agreement, loan
agreement or instrument to which the Guarantor is a party or by which it or its properties may be
bound or affected.



(C) There are no actions, suits or proceedings pending or threatened against or affecting the
Guarantor or the property of the Guarantor before any court or governmental department, commission,
board, bureau, agency or instrumentality, domestic or foreign, which, if determined adversely to
the Guarantor would have a material adverse effect on the financial condition, property, or
operations of the Guarantor or the Guarantor’s ability to perform under this Agreement.



(D) Guarantor will receive a direct or indirect material benefit from the transaction(s)
contemplated herein and/or arising out of Borrower’s Indebtedness.



(E) This Agreement, when executed and delivered by Guarantor, will constitute a valid, legal
and binding obligation of Guarantor enforceable against Guarantor in accordance with its terms,
except as may be limited by general principles of equity and bankruptcy, insolvency and similar
laws.

(F) Any payments required to be made by the Guarantor hereunder shall be made in full, “net
taxes”. The Guarantor agrees to pay the Cat Financial such additional amounts as will be necessary
to cover any and all (i) taxes or assessments, governmental charges or levies, duties, fees,
deductions or withholding, restrictions or conditions of any nature or other amounts imposed by, or
on behalf of, any government or any taxing authority thereof or therein, or (ii) any stamp, duty or
documentary taxes or charges imposed by any government or any taxing authority thereof or therein,
resulting from, related to or in connection with this Agreement, the Loan Agreement (or any
advances made thereunder) or any other related documents or instruments delivered in connection
herewith or the transactions contemplated hereby.



(G) Copies of the Loan Agreement and all related documents have been made available to
the Guarantor and it is familiar with the contents.



SECTION 11. Additional Documents. Upon the reasonable request of Cat Financial,
Guarantor will, at any time, and from time to time, duly execute and deliver to Cat Financial any
and all such further instruments and documents, and supply such additional information, as may be
necessary or advisable in the opinion of Cat Financial, to obtain the full benefits of this
Agreement.



SECTION 12. Transfer of Indebtedness. This Agreement is for the benefit of Cat
Financial and for such other person or persons as may from time to time become or be the holders of
Borrower’s Indebtedness hereby guaranteed and this Agreement shall be transferable and negotiable,
with the same force and effect and to the same extent as Borrower’s Indebtedness may be
transferable, it being understood that, upon the transfer or assignment by Cat Financial of
Borrower’s Indebtedness hereby guaranteed, the legal holder of such Indebtedness shall have all of
the rights granted to Cat Financial under this Agreement. Guarantor hereby recognizes and agrees
that Cat Financial may, from time to time, one or more times, transfer all or any portion of
Borrower’s Indebtedness to one or more third parties. Such transfers may include, but are not
limited to, sales of a participation interest in such Indebtedness in favor of one or more third
party Cat Financials. Guarantor specifically agrees and consents to all such transfers and
assignments and Guarantor further waives any subsequent notice of and right to consent to any such
transfers and assignments as may be provided under applicable law. Guarantor additionally agrees
that the purchaser of a participation interest in Borrower’s Indebtedness will be considered as the
absolute owner of a percentage interest of such Indebtedness and that such a purchaser will have
all of the rights granted to the purchaser under any participation agreement governing the sale of
such a participation interest. Guarantor further waives any right of offset that Guarantor may
have against Cat Financial and/or any purchaser of such a participation interest in Borrower’s
Indebtedness and Guarantor unconditionally agrees that either Cat Financial or such a purchaser may
enforce Guarantor’s obligations and liabilities under this Agreement, irrespective of the failure
or insolvency of Cat Financial or any such purchaser.



Guarantor further agrees that, upon any transfer of all or any portion of Borrower’s
Indebtedness, Cat Financial may transfer and deliver any and all collateral securing repayment of
such Indebtedness (including, but not limited to, any collateral provided by Guarantor) to the
transferee of such Indebtedness and such collateral (again, including but not limited to
Guarantor’s collateral) shall secure any and all of Borrower’s Indebtedness in favor of such a
transferee. Guarantor additionally agrees that, after any such transfer or assignment has taken
place, Cat Financial shall be fully discharged from any and all liability and responsibility to
Borrower (and Guarantor) with respect to such collateral, and the transferee thereafter shall be
vested with all the powers and rights with respect to such collateral.



SECTION 13. Right of Offset. As collateral security for the repayment of Guarantor’s
obligations and liabilities under this Agreement, Guarantor hereby grants Cat Financial, as well as
its successors and assigns, the right to apply, at any time and from time to time, so long as
Borrower is then in default under its Indebtedness guaranteed hereunder, any and all funds that
Guarantor may then have on deposit with or in the possession or control of Cat Financial (or its
successors or assigns and their
subsidiaries and affiliates), towards repayment of any of Borrower’s Indebtedness subject to this
Agreement. In the event such funds are also subject to similar rights of offset in connection with
obligations arising under other loan agreement or guaranty agreements between Guarantor and Cat
Financial, Cat Financial (or any assignee of Cat Financial’s rights) shall apply such funds to the
Guarantor’s obligations hereunder first, before applying such funds to any other obligations of the
Guarantor to the Cat Financial (or any assignee).

provision of this Agreement, and no consent to any departure by Guarantor therefrom, shall be

and then shall be effective only to the specific instance and for the specific purpose for which
given.



SECTION 17. Successors and Assigns Bound. Guarantor’s obligations and liabilities
under this Agreement shall be binding upon Guarantor’s successors, heirs, legatees, devisees,
administrators, executors and assigns. The rights and remedies granted to Cat Financial under this

Agreement.

SECTION 18. Caption Headings and Undefined Terms. Caption headings of the sections
of this Agreement are for convenience purposes only and are not to be used to interpret or to

INTERPRETED, PERFORMED, AND ENFORCED SOLELY IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK,
WITHOUT REFERENCE TO PRINCIPLES OF CONFLICTS OF LAW.



SECTION 20. Severability. If any provision of this Agreement is held to be illegal,
invalid or unenforceable under present or future laws effective during the term hereof, such
provision shall be fully severable, this Agreement shall be construed and enforceable as if the
illegal, invalid or unenforceable provision had never comprised a part of it, and the remaining
provisions of this Agreement shall remain in full force and effect and shall not be affected by the
illegal, invalid or unenforceable provision or by its severance herefrom. Furthermore, in lieu of
such illegal, invalid, or unenforceable provision there shall be added automatically as a part of

as may be possible and legal, valid and enforceable.

hereby contemplated. Guarantor hereby waives personal service of process and consents that service
of process upon it may be made by certified or registered mail, return receipt requested, at its
address specified above and service so made shall be deemed completed on the tenth business day
after such service is deposited in the mail. Nothing herein shall affect the right to serve

Guarantor against Cat Financial involving, directly or indirectly, any matter in any way arising
out of, related to, or connected with this Agreement or the Loan Agreement or any document hereby
or thereby contemplated shall be brought only in a state or federal court located in the State of

jurisdiction claim for itself, the Borrower or the real or personal property of either, immunity
from suit, execution, attachment (whether in aid of execution, before judgment or otherwise) or
other legal process and to the extent that in any such jurisdiction there may be attributed to the
Guarantor, the Borrower or the property of either, such immunity (whether or not claimed), the
