(a) Grantors as Issuers. In the case of each Grantor that is an issuer of Pledged Collateral, such Grantor agrees that it will be bound by the terms of this Security Agreement relating to the Pledged Collateral issued by it and will comply with such terms insofar as such terms are applicable to it.

(e) Such Grantor shall, unless it shall reasonably determine that such Patent, Trademark or Copyright is in no way material to the conduct of its business or operations, promptly sue for infringement, misappropriation or dilution and to recover any and all damages for such infringement, misappropriation or dilution, and shall take such other actions as the Administrative Agent shall deem appropriate under the circumstances to protect such Patent, Trademark or Copyright.

of all Commercial Tort Claims for which the Administrative Agent has not been granted a first priority security interest pursuant to clause (a) to exceed $500,000.

If such Grantor is or becomes the beneficiary of a letter of credit with a face amount in excess of $100,000, it shall promptly, and in any event within two Business Days after becoming a beneficiary, notify the Administrative Agent thereof and cause the issuer and/or confirmation bank to (a) consent to the assignment of any Letter-of-Credit Rights to the Administrative Agent and (b) agree to direct all payments thereunder to a Blocked Account for application to the Obligations, in accordance with Section 2.5(d) of the Credit Agreement, all in form and substance reasonably satisfactory to the Administrative Agent.

If such Grantor fails to obtain any insurance as required by this Section, the Administrative Agent may obtain such insurance at such Grantor’s expense. By purchasing such insurance, the Administrative Agent shall not be deemed to have waived any Default arising from such Grantor’s failure to maintain such insurance or pay any premiums therefor.

4.13    Collateral Access Agreements.

(a) For any location leased by a Grantor or where any Inventory of such Grantor is in the possession or control of any Person other than a Grantor or any of its Subsidiaries (other than a Compressor Location), such Grantor shall obtain Collateral Access Agreements in accordance with Section 6.15 of the Credit Agreement; provided that to the extent a Collateral Access Agreement has not been provided for such location in the timeframes provided in the Credit Agreement, a Rent Reserve for rent, charges and other amounts due or to become due with respect to such location may, subject to the terms of the Credit Agreement, be established by the Administrative Agent in its Permitted Discretion. Such Grantor shall timely and fully pay and perform its material obligations under all leases and other agreements with respect to each leased location or third party warehouse where any Collateral is or may be located.

(b) For each Compressor Location, such Grantor (i) shall not prepare, draft, amend, supplement or modify any gas compression agreement for any Compressor Unit in a manner that adversely affects the rights and security interests of the Administrative Agent hereunder, and (ii) with respect to any gas compression agreement entered into by such Grantor after the Closing Date for any Compressor Location, such Grantor shall use commercially reasonable efforts to include the following provision or a similar provision reasonably acceptable to the Administrative Agent in each such gas compression agreement: “Customer shall provide Natural Gas Services Group, Inc., a Colorado

corporation (“Company”), and its officers, representatives, agents and lenders with access to the site at all times while Company’s Equipment is present on Customer’s locations; provided that, any party not an officer, representative or agent of Company shall (i) not enter the site without the prior consent of Customer, which consent shall not be unreasonably withheld; (ii) adhere to the safety requirements of Customer and Company; and (iii) be accompanied by an officer, representative or agent of Company at all times.” Notwithstanding the foregoing, the refusal of any third party to a gas compression agreement to accept such provision shall not be a Default or Event of Default after the exercise of commercially reasonable efforts thereof.

4.14 Control Agreements. Subject to Section 6.12 of the Credit Agreement, for each Deposit Account, Securities Account and Commodity Account (in each case, other than Excluded Accounts) that such Grantor at any time maintains, such Grantor will, substantially contemporaneously with the opening of such Deposit Account, Securities Account or Commodity Account (other than Excluded Accounts), or within ninety (90) days after the Closing Date for such accounts existing as of the Closing Date, pursuant to a Control Agreement in form and substance satisfactory to the Administrative Agent, pursuant to which such Control Agreement shall cause the depository bank that maintains such Deposit Account, securities intermediary that maintains such Securities Account, or commodities intermediary that maintains such Commodity Account, as applicable, to agree to comply at any time with instructions from the Administrative Agent to such depository bank, securities intermediary or commodities intermediary directing the disposition of funds from time to time credited to such Deposit Account, Securities Account or Commodity Account, without further consent of such Grantor, or take such other action as the Administrative Agent may approve in order to perfect the Administrative Agent’s security interest in such Deposit Account, Securities Account or Commodity Account.

4.16 Assigned Contracts. If requested by the Administrative Agent, such Grantor will use commercially reasonable efforts to secure all consents and approvals necessary or appropriate for the assignment to or for the benefit of the Administrative Agent of any Assigned Contract held by such Grantor and to enforce the security interests granted hereunder. Such Grantor shall fully perform all of its obligations under each of its Assigned Contracts, and shall enforce all of its rights and remedies thereunder, in each case, as it deems appropriate in its business judgment; provided however, that such Grantor shall not take any action or fail to take any action with respect to its Assigned Contracts which would cause the termination of an Assigned Contract. Without limiting the generality of the foregoing, such Grantor shall take all action necessary or appropriate to permit, and shall not take any action which would have any materially adverse effect upon, the full enforcement of all indemnification rights under its Assigned Contracts. Such Grantor shall notify the Administrative Agent and the Lenders in writing, promptly after such Grantor becomes aware thereof, of any event or fact which could give rise to a

material claim by it for indemnification under any of its Assigned Contracts, and shall diligently pursue such right and report to the Administrative Agent on all further developments with respect thereto. Such Grantor shall deposit into a Deposit Account subject to a Deposit Account Control Agreement, all amounts received by such Grantor as indemnification or otherwise pursuant to its Assigned Contracts. If such Grantor shall fail after the Administrative Agent’s demand to pursue diligently any right under its Assigned Contracts, or if an Event of Default then exists, the Administrative Agent may, and at the direction of the Required Lenders shall, directly enforce such right in its own or such Grantor’s name and may enter into such settlements or other agreements with respect thereto as the Administrative Agent or the Required Lenders, as applicable, shall determine. In any suit, proceeding or action brought by the Administrative Agent for the benefit of the Secured Parties under any Assigned Contract for any sum owing thereunder or to enforce any provision thereof, such Grantor shall indemnify and hold the Administrative Agent and Secured Parties harmless from and against all expense, loss or damage suffered by reason of any defense, setoff, counterclaims, recoupment, or reduction of liability whatsoever of the obligor thereunder arising out of a breach by such Grantor of any obligation thereunder or arising out of any other agreement, indebtedness or liability at any time owing from such Grantor to or in favor of such obligor or its successors. All such obligations of such Grantor shall be and remain enforceable only against such Grantor and shall not be enforceable against the Administrative Agent or the Secured Parties. Notwithstanding any provision hereof to the contrary, such Grantor shall at all times remain liable to observe and perform all of its duties and obligations under its Assigned Contracts, and the Administrative Agent’s or any Secured Party’s exercise of any of their respective rights with respect to the Collateral shall not release such Grantor from any of such duties and obligations. Neither the Administrative Agent nor any Secured Party shall be obligated to perform or fulfill any of such Grantor’s duties or obligations under its Assigned Contracts or to make any payment thereunder, or to make any inquiry as to the nature or sufficiency of any payment or property received by it thereunder or the sufficiency of performance by any party thereunder, or to present or file any claim, or to take any action to collect or enforce any performance, any payment of any amounts, or any delivery of any property.

4.17 Additional Grantors. Each Grantor agrees to cause each Domestic Subsidiary that is required to become a party to this Security Agreement pursuant to Section 6.13 of the Credit Agreement to become a Grantor for all purposes of this Security Agreement upon execution and delivery by such Domestic Subsidiary of an Assumption Agreement in the form of Annex 1 hereto.

ARTICLE V

(a) If any “Event of Default” under, and as defined in, the Credit Agreement shall occur and be continuing.

(b) Any Equity Interest which is included within the Collateral shall at any time constitute a Security or the issuer of any such Equity Interest shall take any action to have such interests treated as a Security unless (i) all certificates or other documents constituting such Security have been delivered to the Administrative Agent and such Security is properly defined as such under Article 8 of the UCC of the applicable jurisdiction, whether as a result of actions by the issuer thereof or otherwise, or (ii) the Administrative Agent has entered into a Securities Account Control Agreement with the issuer of such Security or with a securities intermediary relating to such Security and such Security is defined as such under Article 8 of the UCC of the applicable jurisdiction, whether as a result of actions by the issuer thereof or otherwise.

5.2    Remedies.

(a) If any Event of Default shall occur and be continuing, the Administrative Agent may, or at the direction of the Required Lenders, shall exercise any or all of the following rights and remedies:

(i) those rights and remedies provided in this Security Agreement, the Credit Agreement, or any other Loan Document; provided that, this Section 5.2(a) shall not be understood to limit any rights or remedies available to the Administrative Agent and the Secured Parties prior to an Event of Default;

(ii) those rights and remedies available to a secured party under the UCC (whether or not the UCC applies to the affected Collateral) or under any other applicable law (including, without limitation, any law governing the exercise of a bank’s right of setoff or bankers’ lien) when a debtor is in default under a security agreement;

(iii)    give notice of sole control or any other instruction under any Control

Agreement and take any action therein with respect to such Collateral;

(iv) without notice (except as specifically provided in Section 7.1 or elsewhere herein or in the Credit Agreement), demand or advertisement of any kind to any Grantor or any other Person, enter the premises of any Grantor where any Collateral is located (through self-help and without judicial process) to collect, receive, assemble, process, appropriate, sell, lease, assign, grant an option or options to purchase or otherwise dispose of, deliver, or realize upon, the Collateral or any part thereof in one or more parcels at public or private sale or sales (which sales may be adjourned or continued from time to time with or without notice and may take place at any Grantor’s premises or elsewhere), for cash, on credit or for future delivery without assumption of any credit risk, and upon such other terms as the Administrative Agent may deem commercially reasonable; and

(v) concurrently with written notice to the applicable Grantor, transfer and register in its name or in the name of its nominee the whole or any part of the Pledged Collateral, to exchange certificates or instruments representing or evidencing Pledged Collateral for certificates or instruments of smaller or larger denominations, to exercise the voting and all other rights as a holder with respect thereto, to collect and receive all cash dividends, interest, principal and other distributions made thereon and to otherwise act with respect to the Pledged Collateral as though the Administrative Agent was the outright owner thereof.

(b) The Administrative Agent, on behalf of the Secured Parties, may comply with any applicable state or federal law requirements in connection with a disposition of the Collateral and compliance will not be considered to adversely affect the commercial reasonableness of any sale of the Collateral.

(c) The Administrative Agent shall have the right upon any such public sale or sales and, to the extent permitted by law, upon any such private sale or sales, to purchase for the benefit of the Administrative Agent and the Secured Parties, the whole or any part of the Collateral so sold, free of any right of equity redemption, which equity redemption the Grantor hereby expressly releases.

(d) Until the Administrative Agent is able to effect a sale, lease, or other disposition of Collateral, the Administrative Agent shall have the right to hold or use Collateral, or any part thereof, to

the extent that it deems appropriate for the purpose of preserving Collateral or its value or for any other purpose deemed appropriate by the Administrative Agent. The Administrative Agent may, if it so elects, seek the appointment of a receiver or keeper to take possession of Collateral and to enforce any of the Administrative Agent’s remedies (for the benefit of the Administrative Agent and Secured Parties), with respect to such appointment without prior notice or hearing as to such appointment.

(e) Notwithstanding the foregoing, neither the Administrative Agent nor any Secured Party shall be required to (i) make any demand upon, or pursue or exhaust any of their rights or remedies against, any Grantor, any other obligor, guarantor, pledgor or any other Person with respect to the payment of the Obligations or to pursue or exhaust any of their rights or remedies with respect to any Collateral therefor or any direct or indirect guarantee thereof, (ii) marshal the Collateral or any guarantee of the Obligations or to resort to the Collateral or any such guarantee in any particular order, or (iii) effect a public sale of any Collateral.

Each Grantor also acknowledges that any private sale may result in prices and other terms less favorable to the seller than if such sale were a public sale and, notwithstanding such circumstances, agrees that any such private sale shall not be deemed to have been made in a commercially unreasonable manner solely by virtue of such sale being private. The Administrative Agent shall be under no obligation to delay a sale of any of the Pledged Collateral for the period of time necessary to permit any Grantor or the issuer of the Pledged Collateral to register such securities for public sale under the Securities Act of 1933, as amended, or under applicable state securities laws, even if the applicable Grantor and the issuer would agree to do so.

5.3     Gr ant or ’s Obligations Upon Event of Default. Upon the request of the Administrative

(b) permit the Administrative Agent, by the Administrative Agent’s representatives and agents, to enter, occupy and use any premises where all or any part of the Collateral, or the books and records relating thereto, or both, are located, to take possession of all or any part of the Collateral or the books and records relating thereto, or both, to remove all or any part of the Collateral or the books and records relating thereto, or both, and to conduct sales of the Collateral, without any obligation to pay the Grantor for such use and occupancy;

(c) prepare and file, or cause an issuer of Pledged Collateral to prepare and file, with the Securities and Exchange Commission or any other applicable government agency, registration statements, a prospectus and such other documentation in connection with the Pledged Collateral as the Administrative Agent may request, all in form and substance satisfactory to the Administrative Agent, and furnish to the Administrative Agent, or cause an issuer of Pledged Collateral to furnish to the Administrative Agent, any information regarding the Pledged Collateral in such detail as the Administrative Agent may specify;

(f)    deliver to the Administrative Agent the originals or copies of all customer contracts constituting Collateral.

5.4 Grant of Intellectual Property License. For the purpose of enabling the Administrative Agent to exercise the rights and remedies under this Article V, each Grantor hereby (a) grants to the Administrative Agent, for the benefit of the Administrative Agent and the Secured Parties, an irrevocable, nonexclusive license (exercisable without payment of royalty or other compensation to any Grantor) to use, license or sublicense any intellectual property rights now owned or hereafter acquired by such Grantor, and wherever the same may be located, and including in such license access to all media in which any of the licensed items may be recorded or stored and to all computer software and programs used for the compilation or printout thereof and (b) irrevocably agrees that the Administrative Agent may sell any of such Grantor’s Inventory directly to any person, including without limitation persons who have previously purchased the Grantor’s Inventory from such Grantor and in connection with any such sale or other enforcement of the Administrative Agent’s rights under this Security Agreement, may sell Inventory which bears any Trademark owned by or licensed to such Grantor and any Inventory that is covered by any Copyright owned by or licensed to such Grantor and the Administrative Agent may (but shall have no obligation to) finish any work in process and affix any Trademark owned by or licensed to such Grantor and sell such Inventory as provided herein.

ARTICLE VII

GENERAL PROVISIONS

7.1 Waivers. Each Grantor hereby waives notice of the time and place of any public sale or the time after which any private sale or other disposition of all or any part of the Collateral may be made. To the extent such notice may not be waived under applicable law, any notice made shall be deemed reasonable if sent to the Grantors, addressed as set forth in Article VIII, at least ten days prior to (a) the date of any such public sale or (b) the time after which any such private sale or other disposition may be made. To the maximum extent permitted by applicable law, each Grantor waives all claims, damages, and demands against the Administrative Agent or any Secured Party arising out of the repossession, retention or sale of the Collateral, except such as (x) arise solely out of the gross negligence or willful misconduct of the Administrative Agent or such Secured Party as finally determined by a court of competent jurisdiction or (y) result from a claim not involving an act or omission of any Loan Party and that is brought by an Indemnitee against another Indemnitee (other than against the Arranger or Administrative Agent in their capacities as such). To the extent it may lawfully do so, each Grantor absolutely and irrevocably waives and relinquishes the benefit and advantage of, and covenants not to assert against the Administrative Agent or any Secured Party, any valuation, stay, appraisal, extension, moratorium, redemption or similar laws and any and all rights or defenses it may have as a surety now or hereafter existing which, but for this provision, might be applicable to the sale of any Collateral made under the judgment, order or decree of any court, or privately under the power of sale conferred by this Security Agreement, or otherwise. Except as otherwise specifically provided herein, each Grantor hereby waives presentment, demand, protest or any notice (to the maximum extent permitted by applicable law) of any kind in connection with this Security Agreement or any Collateral.

7.2 Limitation on Admi nistr ative Agent ’ s and any Secured Party’ s Duty with Respect to theCollateral. The Administrative Agent shall have no obligation to clean-up or otherwise prepare the Collateral for sale. The Administrative Agent and each Secured Party shall use reasonable care with respect to the Collateral in its possession or under its control. Neither the Administrative Agent nor any Secured Party shall have any other duty as to any Collateral in its possession or control or in the possession or control of any agent or nominee of the Administrative Agent or such Secured Party, or any income thereon or as to the preservation of rights against prior parties or any other rights pertaining thereto. To the extent that applicable law imposes duties on the Administrative Agent to exercise remedies in a commercially reasonable manner, each Grantor acknowledges and agrees that it is commercially

reasonable for the Administrative Agent (a) to fail to incur expenses deemed significant by the Administrative Agent to prepare Collateral for disposition or otherwise to transform raw material or work in process into finished goods or other finished products for disposition, (b) to fail to obtain third party consents for access to Collateral to be disposed of, or to obtain or, if not required by other law, to fail to obtain governmental or third party consents for the collection or disposition of Collateral to be collected or disposed of, (c) to fail to exercise collection remedies against Account Debtors or other Persons obligated on Collateral or to remove Liens on or any adverse claims against Collateral, (d) to exercise collection remedies against Account Debtors and other Persons obligated on Collateral directly or through the use of collection agencies and other collection specialists, (e) to advertise dispositions of Collateral through publications or media of general circulation, whether or not the Collateral is of a specialized nature, (f) to contact other Persons, whether or not in the same business as such Grantor, for expressions of interest in acquiring all or any portion of such Collateral, (g) to hire one or more professional auctioneers to assist in the disposition of Collateral, whether or not the Collateral is of a specialized nature, (h) to dispose of Collateral by utilizing internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capacity of doing so, or that match buyers and sellers of assets, (i) to dispose of assets in wholesale rather than retail markets, (j) to disclaim disposition warranties, such as title, possession or quiet enjoyment, (k) to purchase insurance or credit enhancements to insure the Administrative Agent against risks of loss, collection or disposition of Collateral or to provide to the Administrative Agent a guaranteed return from the collection or disposition of Collateral, or (l) to the extent deemed appropriate by the Administrative Agent, to obtain the services of other brokers, investment bankers, consultants and other professionals to assist the Administrative Agent in the collection or disposition of any of the Collateral. Each Grantor acknowledges that the purpose of this Section 7.2 is to provide non-exhaustive indications of what actions or omissions by the Administrative Agent would be commercially reasonable in the Administrative Agent’s exercise of remedies against the Collateral and that other actions or omissions by the Administrative Agent shall not be deemed commercially unreasonable solely on account of not being indicated in this Section 7.2. Without limitation upon the foregoing, nothing contained in this Section 7.2 shall be construed to grant any rights to any Grantor or to impose any duties on the Administrative Agent that would not have been granted or imposed by this Security Agreement or by applicable law in the absence of this Section 7.2.

7.3 Compromises and Collection of Collateral. The Grantors and the Administrative Agent recognize that setoffs, counterclaims, defenses and other claims may be asserted by obligors with respect to certain of the Receivables, that certain of the Receivables may be or become uncollectible in whole or in part and that the expense and probability of success in litigating a disputed Receivable may exceed the amount that reasonably may be expected to be recovered with respect to a Receivable. In view of the foregoing, each Grantor agrees that the Administrative Agent may at any time and from time to time, if an Event of Default has occurred and is continuing, compromise with the obligor on any Receivable, accept in full payment of any Receivable such amount as the Administrative Agent in its sole discretion shall determine or abandon any Receivable, and any such action by the Administrative Agent shall be commercially reasonable so long as the Administrative Agent acts within its Permitted Discretion based on information known to it at the time it takes any such action.

7.4 Secured Party Performance of Debtor Obligations. Without having any obligation to do so, the Administrative Agent may perform or pay any obligation which any Grantor has agreed to perform or pay in this Security Agreement and the Grantors shall reimburse the Administrative Agent for any amounts paid by the Administrative Agent pursuant to this Section 7.4. The Grantors’ obligation to reimburse the Administrative Agent pursuant to the preceding sentence shall constitute Obligations payable on demand.

7.5 Specific Performance of Certain Covenants. Each Grantor acknowledges and agrees that a breach of any of the covenants contained in Sections 4.1(d), 4.1(e), 4.4, 4.5, 4.6, 4.7, 4.8, 4.9, 4.10, 4.12,

4.13, 4.14, 4.15, 4.16, 4.17, 5.3 or 7.7 that continues beyond applicable cure periods will cause irreparable

injury to the Administrative Agent and the Secured Parties, that the Administrative Agent and Secured Parties have no adequate remedy at law in respect of such breaches and therefore agrees, without limiting the right of the Administrative Agent or the Secured Parties to seek and obtain specific performance of other obligations of the Grantors contained in this Security Agreement, that the covenants of the Grantors contained in the Sections referred to in this Section 7.5 shall be specifically enforceable against the Grantors.

7.6    Dispositions Not Authorized. No Grantor is authorized to sell or otherwise dispose of the

Collateral except as set forth in Section 4.1(d).

7.7    No Waiver; Amendments; Cumulative Remedies. No delay or omission of the

Administrative Agent or any Lender to exercise any right or remedy granted under this Security Agreement

shall impair such right or remedy or be construed to be a waiver of any Default or an acquiescence therein, and any single or partial exercise of any such right or remedy shall not preclude any other or further exercise thereof or the exercise of any other right or remedy. No waiver, amendment or other variation of the terms, conditions or provisions of this Security Agreement whatsoever (other than any Amendment or Assumption Agreement) shall be valid unless in writing signed by the Administrative Agent with the concurrence or at the direction of the Lenders required under Section 11.10 of the Credit Agreement and then only to the extent in such writing specifically set forth. All rights and remedies contained in this Security Agreement or by law afforded shall be cumulative and all shall be available to the Administrative Agent and the Secured Parties until the Obligations have been paid in full.

7.8 Limitation by Law; Severability of Provisions. All rights, remedies and powers provided in this Security Agreement may be exercised only to the extent that the exercise thereof does not violate any applicable provision of law, and all the provisions of this Security Agreement are intended to be subject to all applicable mandatory provisions of law that may be controlling and to be limited to the extent necessary so that they shall not render this Security Agreement invalid, unenforceable or not entitled to be recorded or registered, in whole or in part. Any provision in this Security Agreement that is held to be inoperative, unenforceable, or invalid in any jurisdiction shall, as to that jurisdiction, be inoperative, unenforceable, or invalid without affecting the remaining provisions in that jurisdiction or the operation, enforceability, or validity of that provision in any other jurisdiction, and to this end the provisions of this Security Agreement are declared to be severable.

7.9 Reinstatement. This Security Agreement shall remain in full force and effect and continue to be effective should any petition be filed by or against any Grantor for liquidation or reorganization, should any Grantor become insolvent or make an assignment for the benefit of any creditor or creditors or should a receiver or trustee be appointed for all or any significant part of any Grantor’s assets, and shall continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Obligations, or any part thereof, is, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee of the Obligations, whether as a “voidable preference,” “fraudulent conveyance,” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Obligations shall be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

7.10 Benefit of Agreement. The terms and provisions of this Security Agreement shall be binding upon and inure to the benefit of the Grantors, the Administrative Agent and the Secured Parties

and their respective successors and assigns (including all persons who become bound as a debtor to this Security Agreement), except that no Grantor shall have the right to assign its rights or delegate its obligations under this Security Agreement or any interest herein, without the prior written consent of the Administrative Agent. No sales of participations, assignments, transfers, or other dispositions of any agreement governing the Obligations or any portion thereof or interest therein shall in any manner impair the Lien granted to the Administrative Agent, for the benefit of the Administrative Agent and the Secured Parties, hereunder.

7.11 Survival of Representations. All representations and warranties of the Grantors contained in this Security Agreement shall survive the execution and delivery of this Security Agreement.

7.12 Taxes and Expenses. Any taxes (including income taxes) payable or ruled payable by Federal or State authority in respect of this Security Agreement shall be paid by the Grantors, together with interest and penalties, if any. The Grantors shall reimburse the Administrative Agent for any and all reasonable out-of-pocket expenses and internal charges (including reasonable attorneys’, auditors’ and accountants’ fees and reasonable time charges of attorneys, paralegals, auditors and accountants who may be employees of the Administrative Agent) paid or incurred by the Administrative Agent in connection

with the preparation, execution, delivery, administration, collection and enforcement of this Security Agreement and in the audit, analysis, administration, collection, preservation or sale of the Collateral (subject to the terms of the Credit Agreement, which may also include the expenses and charges associated with any periodic or special audit of the Collateral). Any and all costs and expenses incurred by the Grantors in the performance of actions required pursuant to the terms hereof shall be borne solely by the Grantors.

7.13 Headings. The title of and section headings in this Security Agreement are for convenience of reference only, and shall not govern the interpretation of any of the terms and provisions of this Security Agreement.

7.14 Termination. This Security Agreement shall continue in effect (notwithstanding the fact that from time to time there may be no Obligations outstanding) until (a) the Credit Agreement has terminated pursuant to its express terms and (b) all of the Obligations have been indefeasibly paid and performed in full (or (i) with respect to any outstanding Letters of Credit, a cash deposit or supporting letter of credit has been delivered to the Administrative Agent as required by the Credit Agreement or (ii) with respect to any Obligations that are due and payable under a Secured Bank Product Agreement, such Obligations shall have been paid in full or other arrangements reasonably satisfactory to the applicable Bank Product Provider shall have been made) and no commitments of the Administrative Agent or the Secured Parties which would give rise to any Obligations are outstanding.

7.15 Entire Agreement. This Security Agreement embodies the entire agreement and understanding between the Grantors and the Administrative Agent relating to the Collateral and supersedes all prior agreements and understandings between the Grantors and the Administrative Agent relating to the Collateral.

7.16 CHOICE OF LAW. THIS SECURITY AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS.

7.17 CONSENT TO JURISDICTION. EACH GRANTOR HEREBY IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF ANY UNITED STATES FEDERAL OR TEXAS STATE COURT, IN EITHER CASE, SITTING IN DALLAS COUNTY, TEXAS IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS SECURITY AGREEMENT OR ANY OTHER LOAN DOCUMENT AND EACH GRANTOR HEREBY

IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN ANY SUCH COURT AND IRREVOCABLY WAIVES ANY OBJECTION IT MAY NOW OR HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN SUCH A COURT OR THAT SUCH COURT IS AN INCONVENIENT FORUM. NOTHING HEREIN SHALL LIMIT THE RIGHT OF THE ADMINISTRATIVE AGENT OR ANY SECURED PARTY TO BRING PROCEEDINGS AGAINST ANY GRANTOR IN THE COURTS OF ANY OTHER JURISDICTION. ANY JUDICIAL PROCEEDING BY ANY GRANTOR AGAINST THE ADMINISTRATIVE AGENT OR ANY SECURED PARTY OR ANY AFFILIATE OF THE ADMINISTRATIVE AGENT OR ANY SECURED PARTY INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH THIS SECURITY AGREEMENT OR ANY OTHER LOAN DOCUMENT SHALL BE BROUGHT ONLY IN A COURT IN DALLAS COUNTY, TEXAS.

7.19    Indemnity. Section 11.2 of the Credit Agreement is hereby incorporated by reference

mutatis mutandis, as if stated verbatim herein as agreements and obligations of each Grantor.
