(a) an existing and enforceable negative pledge provision or (b) applicable law to which Grantor is
subject, except (in the case of either of the foregoing clauses (a) and (b)) to the extent such
prohibition is ineffective under the UCC.



Section 3. Representations and Warranties. In addition to the
representations and warranties made by Grantor under the Purchase Agreement and any other
Transaction Document, Grantor hereby makes the following representations and warranties to the
Collateral Agent and each of the Secured Parties:



(a) Except for the lien granted pursuant to this Security Agreement and Permitted Liens,
Grantor owns each item of the Collateral free and clear of any and all liens, encumbrances or
claims of others. Grantor (x) is the record and beneficial owner of the Collateral pledged by it
hereunder constituting instruments or certificates and (y) has rights in or the power to transfer
each other item of Collateral in which a lien is granted by it hereunder, free and clear of any
other lien or encumbrance (other than Permitted Liens).



(b) The security interest granted pursuant to this Security Agreement constitutes a valid and
continuing perfected security interest in favor of the Collateral Agent, for the benefit of the
Secured Parties, in all Collateral subject, in the case of all Collateral in which a security
interest may be perfected by filing a financing statement under the UCC, to the filing of such
financing statements with the appropriate Secretaries of State (or similar governmental authority).
Such security interest shall be prior to all other liens on the Collateral.



(c) Grantor’s jurisdiction of organization, legal name and organizational identification
number, if any, and the location of Grantor’s chief executive office or sole place of business, in
each case as of the date hereof, is specified on Schedule II hereto.



(d) No consent or approval of, notice to or filing with any governmental authority or any
other person or entity or any consent from any person or entity is required for the exercise by the
Collateral Agent of its rights provided for in this Security Agreement or the enforcement of
remedies in respect of the Collateral pursuant to this Security Agreement, including the transfer
of any Collateral, except for (i) filings necessary to perfect and maintain the perfection of the
liens granted under this Security Agreement, and (ii) the approvals, consents, and authorizations
which have been duly obtained, taken, given, or made and are in full force and effect.



(e) This Security Agreement constitutes the legal, valid and binding obligation of Grantor
enforceable against Grantor in accordance with its terms except as limited by applicable
bankruptcy, insolvency, reorganization, moratorium or other laws of general application affecting
enforcement of creditors’ rights.



(f) Neither the execution of this Security Agreement nor the performance of the obligations
created hereunder will conflict with or result in a breach of any other agreement or instrument to
which Grantor is a party or by which it is bound or be in violation or default of any statute,
rule, or decree of any court, administrative agency or governmental body to which it may be
subject. Grantor is not in default with respect to any indenture, loan agreement, mortgage, lease,
deed or other similar agreement to which it is a party or by which it is bound; and



(g) The consummation of the transactions between the Company and each of the Secured Parties
contemplated by the Transaction Documents is of value to Grantor and is reasonably expected to
benefit Grantor directly or indirectly, and is in furtherance of Grantor’s business interests.



Section 4. Covenants and Agreements.



4.1. Grantor shall pay promptly when due all taxes, license fees, assessments and public and
private charges levied or assessed on any of the Collateral, on its use, or on this Security
Agreement; provided, that Grantor shall not be required to pay any such tax, license fee,
assessment or charge whose amount, applicability or validity is being contested in good faith by
appropriate proceedings and for which Grantor has provided adequate reserves in accordance with
GAAP. At its option, the Collateral Agent may discharge taxes, liens, security interests or other
encumbrances at any time levied or placed on the Collateral and may pay for the maintenance,
insurance and preservation of the Collateral and effect compliance with the terms of this Security
Agreement. Grantor agrees to reimburse the Collateral Agent, on demand, for all costs and expenses
incurred by it in connection with such payment or performance and agrees that such reimbursement
obligation shall constitute Secured Obligations.



4.2. Grantor shall, at all times, keep accurate and complete records of the Collateral, and
the Collateral Agent shall have the right to inspect, and make copies of all of Grantor’s books and
records relating to the Collateral during normal business hours, after giving Grantor reasonable
prior notice.



4.3. Grantor agrees, at its own expense, to keep the Collateral insured with companies
reasonably acceptable to the Collateral Agent for such amounts and against such hazards as is
usually carried by companies engaged in similar business and owning similar properties in the same
general jurisdictions or regions that Grantor operates, with losses under the policies payable to
the Collateral Agent or its assigns, if any, for the benefit of the Secured Parties. The
Collateral Agent shall be named as an additional insured under all such insurance policies with
loss payable clauses under said policies payable in the Collateral Agent’s favor, for the benefit
of the Secured Parties. Grantor hereby irrevocably appoints the Collateral Agent as its
attorney-in-fact, such appointment to be exercised after the occurrence and during the continuance
of an Event of Default (as defined below), to make proof of loss and claims for insurance and to
make adjustments with insurers and to receive payment of and execute or endorse all documents,
checks or drafts in connection with payments made with respect to such insurance policies. Grantor
may not make adjustments with insurers except with the Collateral Agent’s prior written consent.
The policies will provide that the insurance may not be altered or canceled by the insurer until
after 30 days written notice to the Collateral Agent. Upon the request of the Collateral Agent,
Grantor shall deliver to the Collateral Agent evidence reasonably satisfactory to the Collateral
Agent that Grantor is in compliance with all insurance requirements set forth in this Security
Agreement, which evidence so requested may include insurance certificates from each relevant
insurer. In the event of damage to or loss, secretion, destruction or theft of the Collateral, or
any portion of the Collateral, whether in whole or in part, upon request of the Collateral Agent
Grantor will pay to the Collateral Agent, for the benefit of the Secured Parties, the amount of all
Secured Obligations attributable to such Collateral, or of the portion of the Secured Obligations
attributable to such Collateral so affected if the value and use of the remainder of the Collateral
are not affected at the time of such occurrence (except to the extent that the Collateral Agent,
for the benefit of the Secured Parties, indefeasibly receive proceeds of insurance covering such
Collateral). The Collateral Agent may, at its option, apply proceeds of insurance, in whole or in
part: (i) to repair or comparably replace the Collateral or any portion of it; or (ii) to satisfy
any of the Secured Obligations attributable to such Collateral pursuant to any Transaction
Document.



4.4. Grantor hereby agrees with the Collateral Agent for the benefit of the Secured Parties
from the date hereof until such date as the Secured Obligations are indefeasibly paid in full in
cash that Grantor will (a) use the Collateral only in its trade or business; (b) maintain all of
the tangible Collateral in good operating order and repair, normal wear and tear excepted; (c) use
and maintain the Collateral only in compliance with any applicable manufacturers recommendations
and all applicable laws; (d) keep all of the Collateral free and clear of any and all liens, claims
and encumbrances, including purchase money security interests, other than those in favor of the
Collateral Agent for the benefit of the Secured Parties and Permitted Liens; (e) remain the sole
owner of the Collateral and not sell, lease, mortgage, hypothecate, license, grant a security
interest in or otherwise transfer or encumber any of the Collateral; (f) not change its state of
incorporation or its name as it appears in official filings in the state of its incorporation
without giving the Collateral Agent at least 60 days’ prior written notice; and (g) promptly notify
the Collateral Agent of (i) any of the Collateral having a value, either independently or in the
aggregate, in excess of $25,000 being lost, stolen, missing, destroyed, materially damaged or worn
out or (ii) any lien, claim or encumbrance other than Permitted Liens attaching to or being made
against any of the Collateral.



4.5. Grantor agrees, on request of the Collateral Agent, to furnish to the Collateral Agent
such further information, to execute and deliver to the Collateral Agent such documents and
instruments (including UCC financing statements) and to do such other acts and things as the
Collateral Agent may at any time reasonably request relating to the perfection or protection of the
security interest in the Collateral created by this Security Agreement or for the purpose of
carrying out the intent of this Security Agreement. Without limiting the foregoing, Grantor shall
cooperate and do all acts deemed necessary or advisable by the Collateral Agent to maintain a
perfected first priority security interest in the Collateral and shall obtain and furnish to the
Collateral Agent any subordinations, releases, landlord, lessor, bailee or mortgagee waivers,
control agreements, and similar documents as may be from time to time requested by, and in form and
substance satisfactory to, the Collateral Agent. Grantor will warrant and defend the Collateral
and the Collateral Agent against all claims by all persons in connection with the Secured
Obligations.



4.6. Grantor authorizes the Collateral Agent to file financing statements, continuations, and
amendments thereto describing the Collateral and containing any other information required by the
applicable UCC, in such form and substance as the Collateral Agent, in its sole discretion, may
determine, including a description of the Collateral as “all assets of the debtor” or similar
designation. Grantor irrevocably grants to the Collateral Agent the power, exercisable after the
occurrence and during the continuance of an Event of Default (as defined below), to sign Grantor’s
name and generally to act on behalf of Grantor to execute and file applications for title,
transfers of title, financing statements, notices of lien, demands for terminations or other
security interests in any of the Collateral and other documents pertaining to any or all of the
Collateral. This power is coupled with an interest and is irrevocable during such time as any of
the Secured Obligations are outstanding. Upon request of the Collateral Agent, Grantor shall, if
any certificate of title be required or permitted by law for any of the Collateral, obtain and
promptly deliver to the Collateral Agent such certificate showing the lien of this Security
Agreement with respect to the Collateral. Grantor ratifies its prior authorization for the
Collateral Agent or any Secured Party to file financing statements and amendments thereto
describing the Collateral and containing any other information required by the UCC, if filed prior
to the date hereof.



Section 5. Remedies.



5.1. Upon the occurrence of an event of default under any Transaction Document (an “Event
of Default”), the Collateral Agent shall have all of the rights and remedies of a secured party
under the UCC, and under any other applicable law and in equity. Without limiting the foregoing,
the Collateral Agent shall have the right to:



(a) declare any or all of the Secured Obligations to be immediately due and payable, without
demand or notice to the Company, Grantor or any other person liable for the Secured Obligations;



(b) require Grantor to promptly assemble the Collateral and make it available to the
Collateral Agent at a place to be designated by the Collateral Agent which is reasonably convenient
to both parties;



(c) take possession of the Collateral and remove same from its existing location(s) without
notice to or consent of Grantor (and Grantor irrevocably authorizes the Collateral Agent to do so);
and store and/or dispose (by public sale or otherwise) of the Collateral at its then existing
location(s) at no charge to the Collateral Agent;



(d) sell or lease any or all items of Collateral at public or private sale or lease at such
time or times as the Collateral Agent may determine and if notice thereof is required by law, any
notice in writing of any such sale or lease by the Collateral Agent to Grantor not less than 10
days prior to the date thereof shall constitute reasonable notice thereof to Grantor;



(e) otherwise lease, dispose of, hold, use, operate, or keep idle such Collateral, all as the
Collateral Agent, in its sole discretion, may determine; and



(f) have the right to bid on and purchase the Collateral at any public or private sale.



5.2. The cost of removal and turnover, including all transportation, of the Collateral upon
the occurrence of an Event of Default will be at Grantor’s expense. If Grantor makes modifications
to the site after the Collateral has been installed which impede the removal of the Collateral, the
cost of removing the impediments and restoring the site will be at Grantor’s expense. If,
following an Event of Default, the Collateral Agent exercises its right to demand that Grantor turn
over the Collateral to the Collateral Agent, the Collateral will be turned over to the Collateral
Agent or its assigns, in the same condition and appearance as when received by Grantor (reasonable
wear and tear excepted) and in good working order and condition, operable in accordance with any
applicable supplier’s then prevailing performance specifications.



5.3. After deducting all expenses of retaking, repairing, holding, transporting, initially
selling the Collateral, the net proceeds (if any) from such sale by the Collateral Agent shall be
applied against Grantor’s obligations in the following priorities: (a) first, to pay all fees, if
any, indemnities, expenses and other amounts (including reasonable fees, charges and disbursements
of counsel to the Collateral Agent) payable to the Collateral Agent in its capacity as such; (b)
second, to pay the Collateral Agent’s costs, charges and expenses in taking, removing, holding,
repairing, selling and disposing of the Collateral and any other expenses due and payable
hereunder; (c) third, to the extent not previously paid by the Company, Grantor or any other person
or entity liable therefore, to pay the Secured Parties all amounts owing in respect of the Secured
Obligations, ratably among such Secured Parties in proportion to the respective amounts described
in this clause (c) payable to them; and (d) lastly, any surplus shall be delivered to the person
lawfully entitled thereto. The Collateral Agent shall have the right to seek any deficiency from
Grantor notwithstanding the Collateral Agent’s repossession of the Collateral, or the Collateral
Agent’s initial or subsequent sale of the Collateral to a third party.



5.4. The foregoing remedies are cumulative and nonexclusive of any other rights and remedies
that the Collateral Agent may have under any other agreement or at law or in equity and may be
exercised individually or concurrently, any or all thereof may be exercised instead of or in
addition to each other or any remedies at law, in equity, or under statute. Except as expressly
provided otherwise herein, Grantor waives notice of sale or other disposition (and the time and
place thereof), and the manner and place of any advertising, and any other notice required to be
given under the UCC. The Collateral Agent shall have no obligation to marshal any of the
Collateral.



5.5. As used herein, the term “UCC” shall mean the Uniform Commercial Code as the
same may, from time to time, be in effect in the State of Texas, provided, however,
in the event that, by reason of mandatory provisions of law, any or all of the perfection or
priority of the security interest in any Collateral is governed by the Uniform Commercial Code as
in effect in a jurisdiction other than the state referred to above, “UCC” shall mean the
Uniform Commercial Code as in effect in such other jurisdiction for purposes of the provisions of
this Security Agreement relating to such perfection or priority and for purposes of definitions
related to such provisions.



Section 6. Waiver of Certain Rights. Grantor hereby unconditionally and
irrevocably waives and agrees not to assert any claim, defense, setoff or counterclaim based on
diligence, promptness, presentment, acceptance, demand, requirements for any demand or notice
hereunder or other requirements of any kind with respect to any Secured Obligation (including any
accrued but unpaid interest thereon) becoming immediately due and payable and any other notice in
respect of the Secured Obligations or any part of them, and any defense arising by reason of any
disability or other defense of the Company, Grantor or any other person or entity liable for the
Secured Obligations.



Section 7. Reinstatement. Grantor agrees that, if any payment made by the
Company or any other person or entity liable for the Secured Obligations and applied to the Secured
Obligations is at any time annulled, avoided, set aside, rescinded, invalidated, declared to be
fraudulent or preferential or otherwise required to be refunded or repaid, or the proceeds of
Collateral are required to be returned by Collateral Agent or any Secured Party to such person or
entity, its estate, trustee, receiver or any other party, including Grantor, under any bankruptcy
law, state or federal law, common law or equitable cause, then, to the extent of such payment or
repayment, any lien or encumbrance or other Collateral securing such liability shall be and remain
in full force and effect, as fully as if such payment had never been made. If, prior to any of the
foregoing, (a) any lien or encumbrance or other Collateral securing Grantor’s liability hereunder
shall have been released or terminated by virtue of the foregoing, such lien or encumbrance or
other Collateral shall be reinstated in full force and effect and such prior release, termination,
cancellation or surrender shall not diminish, release, discharge, impair or otherwise affect the
obligations of Grantor in respect of any lien or encumbrance or other Collateral securing such
obligation or the amount of such payment.



Section 8. Amendments and Waivers.



8.1. None of the terms or provisions of this Security Agreement may be waived, amended,
supplemented or otherwise modified except in accordance with Section 9.5 of the Purchase Agreement
and Section 8 of each Note; provided that no amendment hereto which affects the rights,
duties or obligations of the Collateral Agent shall be effective without the prior written consent
of the Collateral Agent and provided further that this Security Agreement may be amended
without the consent of any Person other than the Collateral Agent in order to add one or more
additional Secured Parties hereto as such.



8.2. No failure to exercise, nor any delay in exercising, on the part of the Collateral
Agent, any right, power or privilege hereunder shall operate as a waiver thereof. No single or
partial exercise of any right, power or privilege hereunder shall preclude any other or further
exercise thereof or the exercise of any other right, power or privilege. A waiver by the
Collateral Agent of any right or remedy hereunder on any one occasion shall not be construed as a
bar to any right or remedy that the Collateral Agent would otherwise have on any future occasion.



Section 9. Remedies Cumulative. The rights and remedies of the Collateral
Agent hereunder are cumulative and nonexclusive of any other rights and remedies that the
Collateral Agent or any other Secured Party may have under any other agreement or at law or in
equity and may be exercised individually or concurrently, any or all thereof may be exercised
instead of or in addition to each other or any remedies at law, in equity, or under statute.



Section 10. Collateral Agent.



10.1. The Collateral Agent shall not have any duties or obligations except those expressly
set forth herein and in the Guaranty. Without limiting the generality of the foregoing, the
Collateral Agent:



(a) shall not be subject to any fiduciary or other implied duties, regardless of whether an
Event of Default has occurred and is continuing; and



(b) shall not have any duty to take any discretionary action or exercise any discretionary
powers, except discretionary rights and powers expressly contemplated hereby or by the Guaranty,
provided that the Collateral Agent shall not be required to take any action (i) that in its
reasonable opinion is or may be contrary to law or to the terms of this Security Agreement or any
other Transaction Document or any other agreement or instrument relating to the Collateral, or
which might or would in its reasonable opinion subject it or any of its directors, officers,
employees or agents to personal or financial liability or (ii) unless it is indemnified hereunder
to its satisfaction (and if any indemnity should become, in the determination of the Collateral
Agent, inadequate, the Collateral Agent may call for additional indemnity and cease to act until
such additional indemnity is given); and



10.2. The Collateral Agent shall not be liable for any action taken or not taken by it (i)
with the consent or at the request of the Required Secured Parties (as defined below) or (ii) in
the absence of its own gross negligence or willful misconduct.



10.3. The Collateral Agent shall not be responsible for or have any duty to ascertain or
inquire into (i) any statement, warranty or representation made in or in connection with this
Security Agreement or any other Transaction Document, (ii) the contents of any certificate, report
or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii)
the performance or observance of any of the covenants, agreements or other terms or conditions set
forth herein or therein or the occurrence of any Event of Default, (iv) the validity,
enforceability, effectiveness or genuineness of this Security Agreement, any other Transaction
Document or any other agreement, instrument or document, or the creation, perfection or priority of
any lien purported to be created by the Transaction Documents, or (v) the value or the sufficiency
of any Collateral, and the Collateral Agent shall incur no liability or responsibility in respect
of the foregoing. The Collateral Agent shall not be responsible for insuring the Collateral or for
the payment of taxes, charges, assessments or liens upon the Collateral or for perfecting or
maintaining the perfection of its security interest in the Collateral purported to be granted
hereby or otherwise as to the maintenance of the Collateral or any filings, including filings of
UCC continuation statements.



10.4. The Collateral Agent shall be entitled to rely upon, and shall not incur any liability
for relying upon, any notice, request, certificate, consent, statement, instrument, document or
other writing (including any electronic message, Internet or intranet website posting or other
distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated
by the proper Person. The Collateral Agent also may rely upon any statement made to it orally or
by telephone and believed by it to have been made by the proper Person, and shall not incur any
liability for relying thereon. The Collateral Agent may, in its sole discretion, retain counsel,
independent accountants and other experts selected by it and may act in reliance upon the advice of
such counsel, independent accountants and other experts concerning all matters pertaining to the
agencies hereby created and its duties hereunder, and shall be held harmless and shall not be
liable for any action taken or omitted to be taken by it in good faith in reliance upon or in
accordance with the statements and advice of such counsel (or counsel to Grantor), accountants and
other experts.



10.5. The Collateral Agent may at any time give notice of its resignation to the Secured
Parties. Upon receipt of any such notice of resignation, the Required Secured Parties (as defined
below) shall have the right to appoint a successor. If no such successor shall have been so
appointed by the Required Secured Parties and shall have accepted such appointment within 30 days
after the retiring Collateral Agent gives notice of its resignation, then the retiring Collateral
Agent may on behalf of the Secured Parties, appoint a successor Collateral Agent; provided
that if the retiring Collateral Agent shall notify the Secured Parties that no Person has accepted
such appointment, then such resignation shall nonetheless become effective in accordance with such
notice and (a) the retiring Collateral Agent shall be discharged from its duties and obligations
hereunder and under the Guaranty and (b) all payments, communications and determinations provided
to be made by, to or through the Collateral Agent shall instead be made by or to each Secured Party
directly, until such time as the Required Secured Parties appoint a successor Collateral Agent as
provided for above in this Section. Upon the acceptance of a successor’s appointment as Collateral
Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers,
privileges and duties of the retiring (or retired) Collateral Agent, and the retiring Collateral
Agent shall be discharged from all of its duties and obligations hereunder or under the Guaranty
(if not already discharged therefrom as provided above in this Section). After the retiring
Collateral Agent’s resignation, the provisions of Sections 10 and 16 shall continue
in effect for the benefit of such retiring Collateral Agent and its related parties in respect of
any actions taken or omitted to be taken by any of them while the retiring Collateral Agent was
acting as Collateral Agent. For all purposes hereunder, the “Required Secured Parties”

to and generally engage in any kind of business with the Company, Grantor and their respective
affiliates as if it were not the collateral agent of the Secured Parties.

is provided with an indemnity from the Grantor or one or more of the Secured Parties, satisfactory
to the Collateral Agent in its sole discretion.

consequential loss or damage of any kind whatsoever, including, but not limited to, lost profits,
even if the Collateral Agent has been advised of the likelihood of such loss or damage and
