Excluded Property solely by virtue of being Proceeds thereof but only to the extent that such Proceeds otherwise independently constitute Excluded Property hereunder.

To the extent that the Collateral is not subject to the UCC, each Debtor collaterally assigns all of such Debtor’s right, title, and interest in and to such Collateral to the Administrative Agent for the benefit of the holders of the Secured Obligations to secure the payment and performance of the Secured Obligations to the full extent that such a collateral assignment is possible under the relevant Law.

     2.2 Avoidance Limitation. Notwithstanding Section 2.1 above, the amount of any Debtor’s Secured Obligations that are secured by its rights in Collateral subject to a Lien in favor of the Administrative Agent hereunder or under any other Security Document shall be limited to the extent, if any, required so that the Liens it has granted under this Security Agreement shall not be subject to avoidance under Section 548 of the Bankruptcy Code of the United States or to being set aside or annulled under any applicable Law relating to fraud on creditors. In determining the limitations, if any, on the amount of any Debtor’s Secured Obligations that are subject to the Lien on such Debtor’s Collateral hereunder pursuant to the preceding sentence, it is the intention of the parties hereto that any rights of subrogation or contribution which such Debtor may have under the Guaranty, any other agreement or applicable Law shall be taken into account.

     2.3 Debtors Remain Liable. Anything herein to the contrary notwithstanding: (a) each Debtor shall remain liable under the Contracts included in the Collateral to the extent set forth therein to perform such Debtor’s obligations thereunder to the same extent as if this Agreement had not been executed; (b) the exercise by the Administrative Agent of any rights hereunder shall not release any Debtor from any obligations under the Contracts included in the Collateral; and (c) the Administrative Agent shall not have any obligation under the Contracts included in the Collateral by reason of this Agreement, nor shall the Administrative Agent be obligated to perform or fulfill any of the obligations of any Debtor thereunder, including any obligation to make any inquiry as to the nature or sufficiency of any payment any Debtor may be entitled to receive thereunder, to present or file any claim, or to take any action to collect or enforce any claim for payment thereunder.

COVENANTS AND AGREEMENTS

Each Debtor covenants and agrees with the Administrative Agent and the holders of the Secured Obligations that, from and after the date of this Agreement until this Agreement terminates in accordance with Section 7.13(a):

     4.1 Covenants in Credit Agreement. Such Debtor shall take, or shall refrain from taking, as the case may be, each action that is necessary to be taken or not taken, as the case may be, so that no Default or Event of Default is caused by the failure to take such action or to refrain from taking such action by such Debtor or any of its Subsidiaries.

     4.2 Maintenance of Insurance. Such Debtor will comply with the provisions of the Credit Agreement governing the maintenance of insurance for any of its assets constituting Collateral. All policies representing liability insurance of the Debtors shall name the Administrative Agent as additional insured in a form reasonably satisfactory to the Administrative Agent and all policies representing casualty insurance of the Debtors insuring Collateral shall name the Administrative Agent as loss payee in a form reasonably satisfactory to the Administrative Agent.

     4.3 Maintenance of Perfected Security Interest; Further Documentation; Filing Authorization; Further Assurances; Power of Attorney.

          (a) Such Debtor shall maintain the security interest created by this Agreement as a perfected first priority security interest prior to all other Liens other than Permitted Prior Liens (and subject to the limitations on perfection and method of perfection provided in Section 5) and shall defend such security interest against the claims and demands of all Persons whomsoever.

          (b) Such Debtor will furnish to the Administrative Agent from time to time statements and schedules further identifying and describing the assets and property of such Debtor and such other reports in connection with the Collateral as the Administrative Agent may reasonably request, all in reasonable detail.

          (c) Subject in each case to Section 5, each Debtor further agrees to take any other action reasonably requested by the Administrative Agent to insure the attachment, perfection and priority of, and the ability of the Administrative Agent to enforce, the security interest in any and all of the Collateral including, without limitation, (i) executing, delivering and, where appropriate, filing financing statements and amendments relating thereto under the UCC, to the extent, if any, that any Debtor’s signature thereon is required therefor; (ii) causing the Administrative Agent’s name to be noted as secured party on any certificate of title for a titled good if such notation is a condition to attachment, perfection or priority of, or ability of the Administrative Agent to enforce, the security interest in such Collateral; (iii) complying with any provision of any statute, regulation or treaty of the United States or any other country as to any Collateral if compliance with such provision is a condition to the attachment, perfection or priority of, or the ability of the Administrative Agent to enforce, the security interest in such Collateral; and (iv) taking all actions required by the UCC or by other law, as applicable in any relevant Uniform Commercial Code jurisdiction, or by other law as applicable in any foreign jurisdiction.

          (d) Each Debtor hereby irrevocably authorizes the Administrative Agent at any time and from time to time to file in any jurisdiction in which the Uniform Commercial Code has been adopted any initial financing statements and amendments thereto that (a) indicate the Collateral (i) as all assets of each Debtor or words of similar effect, or (ii) as being of an equal or lesser scope or with greater detail, and (b) contain any other information required by the UCC for the sufficiency or filing office acceptance of any initial financing statement or amendment. Each Debtor agrees to furnish any such information to the Administrative Agent promptly upon request. Each Debtor also ratifies its authorization for the Administrative Agent

to have filed in any Uniform Commercial Code jurisdiction any like initial financing statements or amendments thereto if filed prior to the date hereof and in respect of this Agreement.

          (e) During the existence of an Event of Default,

          (i) At Administrative Agent’s request, each Debtor shall take any actions reasonably requested by Administrative Agent with respect to such Event of Default, including diligently endeavoring to cure any material defect existing or claimed with respect to any Collateral, and taking all reasonably necessary and desirable steps for the defense of any legal proceedings affecting any Collateral, including the employment of counsel, the prosecution or defense of litigation, and the release or discharge of all adverse claims;

          (ii) Administrative Agent, whether or not named as a party to any legal proceedings, is authorized to take any additional steps as Administrative Agent deems necessary or desirable for the defense of any such legal proceedings or the protection of the validity or priority of this Agreement and the liens, security interests, and assignments created hereunder, including the employment of independent counsel, the prosecution or defense of litigation, the compromise or discharge of any adverse claims made with respect to any Collateral and the payment or removal of prior liens or security interests, and the reasonable expenses of Administrative Agent in taking such action shall be paid by the Debtors; and

          (iii) Each Debtor agrees that, if such Debtor fails to perform under this Agreement or any other Loan Document, Administrative Agent may, but shall not be obligated to, perform such Debtor’s obligations under this Agreement or such other Loan Document, and any reasonable expenses incurred by Administrative Agent in performing such Debtor’s obligations shall be paid by such Debtor. Any such performance by Administrative Agent may be made by Administrative Agent in reasonable reliance on any statement, invoice, or claim, without inquiry into the validity or accuracy thereof. The amount and nature of any expense of Administrative Agent hereunder shall be conclusively established by a certificate of any officer of Administrative Agent absent manifest error.

          (f) Debtor irrevocably appoints Administrative Agent as Debtor’s attorney in fact, with full authority to act during the existence of an Event of Default for Debtor and in the name of Debtor, to take any action and execute any agreement which Administrative Agent deems necessary or advisable to accomplish the purposes of this Agreement, including the matters that Administrative Agent is expressly authorized to take pursuant to this Agreement (including the matters described in paragraph (c) above), and instituting proceedings Administrative Agent deems necessary or desirable to enforce the rights of Administrative Agent with respect to this Agreement.

     4.4 Changes in Name, etc. Such Debtor will not, except upon 10 days’ prior written notice to the Administrative Agent (or such shorter period as may be agreed to by the Administrative Agent in its sole discretion) and the taking of all actions and the execution of all documents reasonably requested by the Administrative Agent to maintain the validity, perfection

and priority of the security interests provided for herein: (a) change its type of organization, jurisdiction of organization or other legal structure from that referred to in Section 3.3, (b) change its organizational number if it has one, or (c) change its name.

     4.5 Delivery of Instruments, Chattel Paper, and Documents. If any amount payable under or in connection with any of the Collateral is or becomes evidenced by any Instrument or Chattel Paper, such Instrument or Chattel Paper shall, to the extent required by Section 5, be immediately delivered to the Administrative Agent, duly indorsed in a manner reasonably satisfactory to the Administrative Agent, to be held as Collateral pursuant to this Agreement. If any goods are or become covered by a negotiable Document, such Document shall, to the extent required by Section 5, be immediately delivered to the Administrative Agent to be held as Collateral pursuant to this Agreement.

     4.6 Investment Property. With respect to Investment Property (other than Excluded Stock) and Pledged Equity:

          (a) If any Debtor shall at any time hold or acquire any Pledged Equity which consists of certificated securities, whether as a stock split, stock dividend, or other distribution with respect to Pledged Equity, or otherwise, such Debtor shall promptly, and in any event within thirty (30) days after receipt thereof, deliver the same to the Administrative Agent, accompanied by such instruments of transfer or assignment duly executed in blank as the Administrative Agent may from time to time specify. If any Pledged Equity now owned or hereafter acquired by any Debtor consists of uncertificated securities and is issued to such Debtor or its nominee directly by the issuer thereof, such Debtor shall immediately notify the Administrative Agent thereof, and shall take any actions reasonably requested by the Administrative Agent to enable the Administrative Agent to obtain “control” (within the meaning of Section 8-106 of the UCC) with respect thereto. If any Pledged Equity, whether certificated securities or uncertificated securities, or other Investment Property (including Securities Accounts and commodities accounts) now or hereafter acquired by any Debtor is held or acquired by such Debtor or its nominee through a securities intermediary or commodity intermediary, such Debtor shall immediately notify the Administrative Agent thereof and shall take any actions reasonably requested by the Administrative Agent to enable the Administrative Agent to obtain “control” (within the meaning of Section 8-106 and/or Section 9-106 of the UCC, as applicable) with respect thereto, including the execution of Control Agreements reasonably acceptable to the Administrative Agent. To the extent that the Administrative Agent has the right pursuant to the foregoing to give entitlement orders or instructions or directions to any issuer, securities intermediary or commodity intermediary or to withhold its consent to the exercise of any withdrawal or dealing rights by any Debtor, the Administrative Agent agrees with each Debtor that the Administrative Agent shall not give any such entitlement orders or instructions or directions to any such issuer, securities intermediary or commodity intermediary, and shall not withhold its consent to the exercise of any withdrawal or dealing rights by any Debtor, unless an Event of Default has occurred and is continuing.

          (b) So long as no Event of Default has occurred and is continuing, each Debtor shall be entitled:

          (i) to exercise, in a manner not inconsistent with the terms hereof, the voting power with respect to the Pledged Equity of such Debtor, and for that purpose the Administrative Agent shall (if any Pledged Equity shall be registered in the name of the Administrative Agent or its nominee) execute or cause to be executed from time to time, at the expense of the Borrower, such proxies or other instruments in favor of such Debtor or its nominee, in such form and for such purposes as shall be reasonably requested by such Debtor, to enable it to exercise such voting power with respect to the Pledged Equity; and

          (ii) except as otherwise provided herein or in the Credit Agreement, to receive and retain for its own account any and all payments, proceeds, dividends, distributions, property, assets, or rights to the extent such are permitted pursuant to the terms of the Credit Agreement, other than (x) stock or liquidating dividends or (y) other dividends or other amounts payable under or in connection with any recapitalization, restructuring, or other non-ordinary course event (the dividends and amounts in this clause (y) being “Extraordinary Payments”), paid, issued or distributed from time to time in respect of the Pledged Equity. During the continuation of an Event of Default, if any Extraordinary Payment is paid or payable, then such sum shall be paid by each such Debtor to the Administrative Agent promptly, and in any event within ten (10) Business Days after receipt thereof, to be held by the Administrative Agent as additional collateral hereunder.

          (c) Upon the occurrence and during the continuance of any Event of Default, all rights of each Debtor to exercise or refrain from exercising the voting and other consensual rights that it would otherwise be entitled to exercise pursuant to Section 4.6(b) and to receive the payments, proceeds, dividends, distributions, property, assets, or rights that the Debtor would otherwise be authorized to receive and retain pursuant to Section 4.6(b) shall cease, and thereupon the Administrative Agent shall be entitled to exercise all voting power with respect to the Pledged Equity and to receive and retain, as additional collateral hereunder, any and all payments, proceeds, dividends, distributions, property, assets, or rights at any time declared or paid upon any of the Pledged Equity during such an Event of Default and otherwise to act with respect to the Pledged Equity as outright owner thereof.

          (d) All payments, proceeds, dividends, distributions, property, assets, instruments or rights that are received by each Debtor contrary to the provisions of this Section 4.6 shall be received and held in trust for the benefit of the Administrative Agent, shall be segregated by each Debtor from other funds of such Debtor and shall be forthwith paid over to the Administrative Agent as Pledged Equity in the same form as so received (with any necessary endorsement).

          (e) If such Debtor is an issuer of Pledged Equity, such Debtor agrees that (i) it will be bound by the terms of this Agreement relating to the Pledged Equity issued by it and will comply with such terms insofar as such terms are applicable to it and (ii) it will comply with instructions received by it pursuant to the terms of Section 4.6(f) with respect to the Pledged Equity issued by it. In addition, if any such Debtor is a partnership or a limited liability company, such Debtor (i) confirms that none of the terms of any equity interest issued by it provides that such equity interest is a “security” within the meaning of the UCC, (ii) agrees that it

will take no action to cause or permit any such equity interest to become a security, (iii) agrees that it will not issue any certificate representing any such equity interest and (iv) agrees that if, notwithstanding the foregoing, any such equity interest shall be or become a security, such Debtor will (and the Debtor that holds such equity interest hereby instructs such issuing Debtor to) comply with reasonable instructions originated by the Administrative Agent without further consent by such Debtor.

          (f) Each Debtor hereby authorizes and instructs each issuer of any Pledged Equity pledged by such Debtor hereunder to (i) comply with any instruction received by it from the Administrative Agent in writing that (x) states that an Event of Default has occurred and is continuing and (y) is otherwise in accordance with the terms of this Agreement, without any other or further instructions from such Debtor, and each Debtor agrees that each such issuer shall be fully protected in so complying, and (ii) unless otherwise expressly permitted hereby, pay any dividends or other payments with respect to the Pledged Equity directly to the Administrative Agent.

     4.7 Deposit Accounts. (a) For each Deposit Account listed on Schedule 3.9 that has a balance of $5,000,000 or more as of the Closing Date (other than Deposit Accounts maintained with the Administrative Agent, trust accounts and payroll accounts), the Debtor maintaining such Deposit Account will take any actions requested by the Administrative Agent to enable the Administrative Agent to obtain “control” (within the meaning of Section 9-104 of the UCC) with respect thereto, including the execution of Control Agreements reasonably acceptable to the Administrative Agent.

          (b) For each Deposit Account created by a Debtor after Closing Date, the Debtor creating and maintaining such Deposit Account shall provide 10 days written notice (or such lesser period as the Administrative Agent may agree) to the Administrative Agent prior to the creation of such Deposit Account and, if at the time of its creation, such Deposit Account has a balance of $5,000,000 or more, take any actions requested by the Administrative Agent to enable the Administrative Agent to obtain “control” (within the meaning of Section 9-104 of the UCC) with respect thereto, including the execution of Control Agreements reasonably acceptable to the Administrative Agent.

          (c) Notwithstanding the foregoing, (i) if the collective balance of any Deposit Accounts not subject to the Administrative Agent’s “control” at any time equals or exceeds $10,000,000, then the Debtors maintaining such Deposit Accounts shall take such action as is necessary to enable the Administrative Agent to obtain “control” with respect to such Deposit Accounts, including the execution of Control Agreements reasonably acceptable to the Administrative Agent, such that, after giving effect thereto, the collective balance of all such Deposit Accounts not subject to the Administrative Agent’s “control” is less than $10,000,000 and (ii) the Administrative Agent agrees with each Debtor that the Administrative Agent will not give any instructions to a depositary bank directing the disposition of funds from time to time credited to any Deposit Account or withhold any withdrawal rights from any Debtor, unless an Event of Default has occurred and is continuing.

     4.8 Modifications of Receivables, Chattel Paper, Instruments and Payment Intangibles. No Debtor will, without the Administrative Agent’s prior written consent (which

consent shall not be unreasonably withheld or delayed): (a) compromise or grant any extension of the time of payment of any of the Collateral consisting of Receivables, Chattel Paper, Instruments or payment intangibles, (b) settle the same for less than the full amount thereof, (c) release, wholly or partly, any obligor liable for the payment thereof or (d) allow any credit or discount whatsoever thereon; provided, that so long as no Event of Default has occurred and is continuing, this Section 4.8 shall not restrict any extensions, credits, discounts, compromises or settlements granted or made by any Debtor in the ordinary course of such Debtor’s business and consistent with such prudent practices used in industries that are the same as or similar to those in which such Debtor is engaged.

     4.9 Intellectual Property. With respect to Intellectual Property:

          (a) Such Debtor (either itself or through licensees) will (i) continue to use each Trademark necessary to the conduct of its business in order to maintain such Trademark in full force free from any claim of abandonment for non-use, (ii) use such Trademark with the appropriate notice of registration and substantially all other notices and legends required by applicable Laws, (iii) not knowingly adopt or use any mark which is confusingly similar or a colorable imitation of such Trademark unless the Administrative Agent, for the ratable benefit of the Secured Parties, shall obtain a perfected security interest in such mark pursuant to this Agreement, and (iv) not (and not knowingly permit any licensee or sublicensee thereof to) do any act or knowingly omit to do any act whereby such Trademark necessary to the conduct of its business may become invalidated or impaired in any way;

          (e) Such Debtor will notify the Agents and the Lenders immediately if it knows, or has reason to know, that any application or registration relating to any Intellectual Property necessary for the conduct of its business may become forfeited, abandoned or dedicated to the public, or of any adverse determination or development (including, without limitation, the institution of, or any such determination or development in, any proceeding in the United States Patent and Trademark Office, the United States Copyright Office) regarding such Debtor’s ownership of, or the validity of, any such Intellectual Property or such Debtor’s right to register the same or to own and maintain the same;

          (f) Whenever such Debtor, either by itself or through any agent, employee, licensee or designee, shall file an application for the registration of any Intellectual Property necessary for the conduct of its business with the United States Patent and Trademark Office, the United States Copyright Office, such Debtor shall report such filing to the Administrative Agent within 30 days after the date on which such filing occurs. Upon request of the Administrative Agent, such Debtor shall promptly execute and deliver, and have recorded, any and all agreements, instruments, documents, and papers as the Administrative Agent may reasonably request to evidence the security interest granted hereunder to the Administrative Agent for the benefit of the holders of the Secured Obligations in any Copyright, Patent or Trademark necessary for the conduct of its business and the goodwill and general intangibles of such Debtor relating thereto or represented thereby;

          (g) Such Debtor will take commercially reasonable and necessary steps, including, without limitation, in any proceeding before the United States Patent and Trademark Office and the United States Copyright Office, to maintain and pursue each application relating to any Intellectual Property necessary for the conduct of its business (and to obtain the relevant registration) and to maintain each registration of such Intellectual Property, including, without limitation, filing of applications for renewal, affidavits of use and affidavits of incontestability; and

          (h) In the event that any Intellectual Property necessary for the conduct of its business is infringed, misappropriated or diluted by a third party, such Debtor shall (i) take such actions as such Debtor shall reasonably deem appropriate under the circumstances to protect such Intellectual Property and (ii) if such Intellectual Property is of material economic value, promptly notify the Administrative Agent after it learns thereof and take such actions as such Debtor shall reasonably deem appropriate under the circumstances, including filing suit for infringement, misappropriation or dilution, to seek injunctive relief where appropriate and to recover any and all damages for infringement, misappropriation or dilution.

     4.10 Rigs. With respect to any Rig now or hereafter owned by a Debtor and with respect to which a certificate of title has been issued, such Debtor agrees to take such action (or cause its Subsidiaries to take such action), including endorsing certificates of title or executing applications for transfer of title, as is reasonably required by the Administrative Agent to enable it to properly perfect and protect its Lien on such Rigs and to transfer the same.

The perfection of the security interest granted in Section 2 above in, respectively, Chattel Paper (whether tangible or electronic) and Instruments will, prior to the occurrence of an Event of Default (and after the occurrence of an Event of Default unless the Administrative Agent has required that further actions are taken with respect to the perfection thereof), be effected solely by filing an appropriate financing statement under the applicable Uniform Commercial Code so long as (a) with respect to all Chattel Paper and Instruments, the aggregate face amount of all such Chattel Paper and Instruments does not exceed $10,000,000 and (b) with respect to any individual Chattel Paper or Instrument, the face amount thereof does not exceed $5,000,000.

SECTION 6.

REMEDIAL PROVISIONS

During the existence of an Event of Default, the Administrative Agent may, at the Administrative Agent’s option, exercise one or more of the remedies specified elsewhere in this Agreement or the following remedies:

     6.1 General Interim Remedies.

          (a) To the extent permitted by Law, the Administrative Agent may exercise all the rights and remedies of a secured party under the UCC.

          (b) The Administrative Agent may prosecute actions in equity or at law for the specific performance of any covenant or agreement herein contained or in aid of the execution of any power herein granted or for the enforcement of any other appropriate legal or equitable remedy.

          (c) The Administrative Agent may require any Debtor to promptly assemble any tangible Collateral of such Debtor and make it available to the Administrative Agent at a place to be designated by the Administrative Agent. The Administrative Agent may occupy any premises owned or leased by any Debtor where the Collateral is assembled for a reasonable period in order to effectuate the Administrative Agent’s rights and remedies hereunder or under law, without obligation to any Debtor with respect to such occupation.

     6.2 Receivables, Chattel Paper, Instruments and Payment Intangibles. During the existence of an Event of Default, the Administrative Agent may establish Collateral Accounts for the purpose of collecting the payments due to the Debtors under any Contracts or otherwise with respect to the Receivables, Chattel Paper, Instruments and/or payment intangibles and holding the proceeds thereof, and may, or may direct the Debtors to, instruct all makers and/or all obligors with respect thereto to make all payments with respect to such Collateral directly to the Administrative Agent for deposit into such Collateral Account. After such direction to the Debtors, all payments, whether of principal, interest, or other amounts, under any Contracts or otherwise with respect to the Receivables, Chattel Paper, Instruments and/or payment intangibles shall be directed to such Collateral Accounts until such direction is revoked in writing by the Administrative Agent. All such payments which may from time to time come into the possession of any Debtor shall be held in trust for the Administrative Agent, segregated from the other funds of such Debtor, and delivered to the Administrative Agent immediately in the form received with any necessary endorsement for deposit into such Collateral Account, such delivery in no event to be later than one Business Day after receipt thereof by the applicable Debtor. Each Debtor agrees to execute any documents reasonably requested by the Administrative Agent to create any Collateral Account and pledge it to the Administrative Agent. In connection with the foregoing, the Administrative Agent shall have the right at any time during the existence of an Event of Default to take any of the following actions, in the Administrative Agent’s own name or in the name of the applicable Debtor: compromise or extend the time for payment of any payments due with respect to any Instrument or Chattel Paper upon such terms as the Administrative Agent may reasonably determine; endorse the name of the applicable Debtor, on checks, instruments, or other evidences of payment with respect to any such Collateral; make written or verbal requests for verification of amount owing on any such Collateral from the maker thereof or obligor thereunder; open mail addressed to such Debtor which the Administrative Agent reasonably believes relates to any such Collateral, and, to the extent of checks or other payments with respect to any such Collateral, dispose of same in accordance with this Agreement; take action in the Administrative Agent’s name or the applicable Debtor’s name, to enforce collection; and take all other action necessary to carry out this Agreement and give effect to the Administrative Agent’s rights hereunder. Costs and expenses incurred by the Administrative Agent in collection and enforcement of amounts owed under any Contracts or otherwise with respect to the Receivables, Chattel Paper, Instruments and/or payment intangibles, including attorneys’ fees and out-of-pocket expenses, shall be reimbursed by the applicable Debtor to the Administrative Agent on demand. If at any time no Event of Default exists, then upon request of the Borrower the Administrative Agent shall promptly revoke any instructions to account debtors to make payment to the Collateral Accounts and shall pay the amounts in the Collateral Accounts to the Debtors as their interests may appear.

     6.3 Contracts. During the existence of an Event of Default, the Administrative Agent may, at its option, exercise one or more of the following remedies with respect to the Contracts that constitute Collateral:

          (a) (i) take any action permitted under Section 6.2 and (ii) in the place and stead of the applicable Debtor, exercise any other rights of such Debtor under the Contracts in accordance with the terms thereof. Without limitation of the foregoing, each Debtor agrees that under the foregoing circumstances, the Administrative Agent may give notices, consents and demands and make elections under the Contracts, modify or waive the terms of the Contracts and

enforce the Contracts, in each case, to the same extent and on the same terms as such Debtor might have done in accordance with the terms of such Contracts and applicable Law. It is understood and agreed that notwithstanding the exercise of such rights and/or the taking or such actions by the Administrative Agent, such Debtor shall remain liable for performance of its obligations under the Contracts; and

          (b) upon receipt by the Administrative Agent of notice from any counterparty to any Contract of such Person’s intent to terminate such Contract, the Administrative Agent shall be entitled to (i) cure or cause to be cured the condition giving rise to such Person’s right of termination of such Contract, or (ii) acquire and assume (or assign and cause the assumption by a third party of) the rights and obligations of the applicable Debtor under such Contract.

     6.4 Pledged Equity.

          (a) Each Debtor recognizes that the Administrative Agent may be unable to effect a public sale of any or all the Pledged Equity, by reason of certain prohibitions contained in the Securities Act and applicable state securities laws or otherwise, and may be compelled to resort to one or more private sales thereof to a restricted group of purchasers which will be obliged to agree, among other things, to acquire such securities for their own account for investment and not with a view to the distribution or resale thereof. Each Debtor acknowledges and agrees that any such private sale may result in prices and other terms less favorable than if such sale were a public sale and, notwithstanding such circumstances, agrees that any such private sale shall be deemed to have been made in a commercially reasonable manner. The Administrative Agent shall be under no obligation to delay a sale of any of the Pledged Equity for the period of time necessary to permit the issuer thereof to register such securities for public sale under the Securities Act, or under applicable state securities laws, even if such issuer would agree to do so.

          (b) Each Debtor agrees to use its commercially reasonable efforts to do or cause to be done all such other acts as may be necessary to make such sale or sales of all or any portion of the Pledged Equity pursuant to this Section 6.4 valid and binding and in compliance with any and all other applicable Laws; provided that, notwithstanding the foregoing, each Debtor agrees to use its best efforts to obtain all Affiliate consents and approvals and cause to be done all such other acts by any Affiliate as may be necessary to make such sale or sales of all or any portion of the Pledged Equity pursuant to this Section 6.4 valid and binding and in compliance with any and all other applicable Laws. Each Debtor further agrees that a breach of any of the covenants contained in this Section 6.4 will cause irreparable injury to the Administrative Agent and the holders of the Secured Obligations, that the Administrative Agent and the holders of the Secured Obligations have no adequate remedy at law in respect of such breach and, as a consequence, that each and every covenant contained in this Section 6.4 shall be specifically enforceable against such Debtor, and such Debtor hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants except for a defense that no Event of Default has occurred.

     6.5 Foreclosure.

          (a) The Administrative Agent may foreclose on the Collateral in any manner permitted by the courts of or in the State of New York or the jurisdiction in which any Collateral is located. If the Administrative Agent should institute a suit for the collection of the Secured Obligations and for the foreclosure of this Agreement, the Administrative Agent may at any time before the entry of a final judgment dismiss the same, and take any other action permitted by this Agreement.

          (b) To the extent permitted by law, the Administrative Agent may exercise all the foreclosure rights and remedies of a secured party under the UCC. In connection therewith, the Administrative Agent may sell any Collateral at public or private sale, at the office of the Administrative Agent or elsewhere, for cash or credit and upon such other terms as the Administrative Agent deems commercially reasonable. The Administrative Agent may sell any Collateral at one or more sales, and the security interest granted hereunder shall remain in effect as to the unsold portion of the Collateral. Each Debtor agrees that to the extent permitted by law such sales may be made without notice. If notice is required by law, each Debtor hereby deems ten days advance notice of the time and place of any public or private sale reasonable notification, recognizing that if any portion of the Collateral is perishable or threatens to decline speedily in value or is of a type customarily sold on a recognized market, shorter notice may be reasonable. The Administrative Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Administrative Agent may adjourn any sale by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was adjourned. In the event that any sale hereunder is not completed or is defective in the opinion of the Administrative Agent, the Administrative Agent shall have the right to cause subsequent sales to be made hereunder. Any statements of fact or other recitals made in any bill of sale, assignment, or other document representing any sale hereunder, including statements relating to the occurrence of an Event of Default, acceleration of the Secured Obligations, notice of the sale, the time, place, and terms of the sale, and other actions taken by the Administrative Agent in relation to the sale may be conclusively relied upon by the purchaser at any sale hereunder. The Administrative Agent may delegate to any agent the performance of any acts in connection with any sale hereunder, including the sending of notices and the conduct of the sale.

     6.6 Application of Proceeds.

          (a) Unless otherwise specified herein, any cash proceeds received by the Administrative Agent from the sale of, collection of, or other realization upon any part of the Collateral or any other amounts received by the Administrative Agent hereunder may be, at the reasonable discretion of the Administrative Agent (i) held by the Administrative Agent in one or more Collateral Accounts as cash collateral for the Secured Obligations or (ii) applied to the Secured Obligations.

          (b) Amounts applied to the Secured Obligations shall be applied in the following order:

      First, to the payment of the costs and expenses of exercising the Administrative Agent’s rights hereunder, whether expressly provided for herein or otherwise; and

          Second, to the payment of the Secured Obligations in the order set forth in Section 8.03 of the Credit Agreement.

Any surplus cash collateral or cash proceeds held by the Administrative Agent after payment in full of the Secured Obligations and the termination of any commitments of the Administrative Agent to any Debtor shall be paid over to such Debtor or to whomever may be lawfully entitled to receive such surplus.

     6.7 Waiver of Certain Rights. To the full extent each Debtor may do so, such Debtor shall not insist upon, plead, claim, or take advantage of any law providing for any appraisement, valuation, stay, extension, or redemption, and such Debtor hereby waives and releases the same, and all rights to a marshaling of the assets of such Debtor, including the Collateral of such Debtor, or to a sale in inverse order of alienation in the event of foreclosure of the liens and security interests hereby created. Such Debtor shall not assert any right under any law pertaining to the marshaling of assets, sale in inverse order of alienation, the administration of estates of decedents or other matters whatever to defeat, reduce, or affect the right of the Administrative Agent under the terms of this Agreement.

     6.8 Remedies Cumulative. The Administrative Agent’s remedies under this Agreement and the Loan Documents to which any Debtor is a party shall be cumulative, and no delay in enforcing this Agreement and the Loan Documents to which any Debtor is a party shall act as a waiver of the Administrative Agent’s rights hereunder.

     6.9 Reinstatement. The obligations of each Debtor under this Agreement shall continue to be effective or automatically be reinstated, as the case may be, if at any time payment of any of the Secured Obligations is rescinded or otherwise must be restored or returned by the Administrative Agent upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of any Debtor or any other obligor or otherwise, all as though such payment had not been made.

SECTION 7.

MISCELLANEOUS

     7.1 Amendments. None of the terms or provisions of this Agreement may be waived, amended, supplemented or otherwise modified except in accordance with Section 10.01 of the Credit Agreement. No consent of any Hedge Bank or any Cash Management Bank (except in such Person’s capacity as a Lender, if applicable) shall be required for any waiver, amendment, supplement or other modification to this Agreement.

     7.2 Notices. All notices, requests and demands to or upon the Administrative Agent hereunder shall be in writing and effected in the manner provided for in Section 10.02 of the Credit Agreement. All notices, requests and demands hereunder to any Debtor shall be in writing and given to it at its address or telecopy number set forth in Annex II attached hereto or at such other address in the United States as may be specified by such Debtor in a written notice delivered to the Administrative Agent in accordance with Section 10.02 of the Credit Agreement.

     7.3 No Waiver by Course of Conduct; Cumulative Remedies; No Duty. No failure to exercise, nor any delay in exercising, on the part of the Administrative 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 Administrative 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 Administrative Agent would otherwise have on any future occasion. The rights and remedies provided herein and in the other Loan Documents are cumulative, may be exercised singly or concurrently and are not exclusive of any other rights or remedies provided by law. The powers conferred on Administrative Agent under this Agreement are solely to protect Administrative Agent’s rights under this Agreement and shall not impose any duty upon it to exercise any such powers. Except as elsewhere provided hereunder, Administrative Agent shall have no duty as to any of the Collateral or as to the taking of any necessary steps to preserve rights against prior parties or any other rights pertaining to the Collateral.

     7.4 Enforcement Expenses; Indemnification.

          (a) Each Debtor agrees to pay, or reimburse the Administrative Agent and each holder of the Secured Obligations for, all costs and expenses incurred in connection with the enforcement, attempted enforcement, exercise, or preservation of any rights or remedies under this Agreement or the other Loan Documents to which such Debtor is a party (including all such costs and expenses incurred during any “workout” or restructuring in respect of the Obligations and during any legal proceeding, including any proceeding under any Debtor Relief Law), including all attorney fees.

          (b) Each Debtor agrees to pay, and to indemnify and hold the Administrative Agent and each holder of the Secured Obligations harmless from, any and all liabilities with respect to, or resulting from any delay in paying, any and all stamp, excise, sales or other taxes which may be payable or determined to be payable with respect to any of the Collateral or in connection with any of the transactions contemplated by this Agreement.

          (c) Each Debtor agrees to pay, and to indemnify and hold the Administrative Agent, each holder of the Secured Obligations, and their respective Affiliates, directors, officers, employees, counsel, agents and attorneys-in-fact (collectively the “Indemnitees”) harmless from, any and all liabilities, obligations, losses, damages, penalties, claims, demands, actions, judgments, suits, costs, expenses and disbursements (including the fees, charges and disbursements of any counsel for any Indemnitee) of any kind or nature whatsoever which may at any time be imposed on, incurred by or asserted against any such Indemnitee in any way relating to or arising out of or in connection with the execution, delivery, enforcement, performance or administration of any Guaranty, this Agreement, or any Loan Document to which such Debtor is a party, in all cases, whether or not caused by or arising, in whole or in part, out of the negligence of the Indemnitee; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such liabilities, obligations, losses, damages, penalties, claims, demands, actions, judgments, suits, costs, expenses or disbursements are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee.

          (d) All amounts due under this Section 7.4 shall be payable upon demand therefor. The agreements in this Section shall survive repayment of the Obligations and all other amounts payable under the Credit Agreement and the other Loan Documents.

     7.5 Successors and Assigns. This Agreement shall be binding upon the successors and assigns of each Debtor and shall inure to the benefit of the Administrative Agent and the holders of the Secured Obligations and their successors and assigns; provided that no Debtor may assign, transfer or delegate any of its rights or obligations under this Agreement without the prior written consent of the Administrative Agent.

     7.6 Set-Off. Each Debtor hereby irrevocably authorizes the Administrative Agent and each Lender at any time and from time to time upon the occurrence and during the continuance of any Event of Default, without prior notice to such Debtor or any other Loan Party, any such notice being waived by such Debtor to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held by, and other indebtedness at any time owing by, such Lender to or for the credit or the account of the respective Debtor against any and all Obligations owing to such Lender under the Credit Agreement, any Guaranty, or under any other Loan Document, now or hereafter existing, irrespective of whether or not the Administrative Agent or such Lender shall have made demand for payment and although such Obligations may be contingent or unmatured or denominated in a currency different from that of the applicable deposit or indebtedness. Any such set-off shall be subject to the notice requirements of Section 10.08 of the Credit Agreement; provided, however, that the failure to give such notice shall not affect the validity of such set-off and application.

     7.7 Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

     7.8 Severability. If any provision of this Agreement is held to be illegal, invalid or unenforceable, (a) the legality, validity and enforceability of the remaining provisions of this Agreement shall not be affected or impaired thereby and (b) the parties shall endeavor in good faith negotiations to replace the illegal, invalid or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the illegal, invalid or unenforceable provisions. The invalidity of a provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

     7.9 Section Headings. The Section headings used in this Agreement are included for convenience of reference only and shall not affect the interpretation of this Agreement.

     7.10 Integration. This Agreement, together with the other Loan Documents, comprises the complete and integrated agreement of the parties on the subject matter hereof and thereof and supersedes all prior agreements, written or oral, on such subject matter.

     7.11 GOVERNING LAW ETC.

EACH DEBTOR IRREVOCABLY AND UNCONDITIONALLY SUBMITS, FOR ITSELF AND ITS PROPERTY, TO THE NONEXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK SITTING IN NEW YORK CITY AND OF THE UNITED STATES DISTRICT COURT OF THE SOUTHERN DISTRICT OF NEW YORK, AND ANY APPELLATE COURT FROM ANY THEREOF, IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR FOR RECOGNITION OR ENFORCEMENT OF ANY JUDGMENT, AND EACH OF THE PARTIES HERETO IRREVOCABLY AND UNCONDITIONALLY AGREES THAT ALL CLAIMS IN RESPECT OF ANY SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN SUCH NEW YORK STATE COURT OR, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN SUCH FEDERAL COURT. EACH OF THE PARTIES HERETO AGREES THAT A FINAL JUDGMENT IN ANY SUCH ACTION OR PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY LAW. NOTHING IN THIS AGREEMENT OR IN ANY OTHER LOAN DOCUMENT SHALL AFFECT ANY RIGHT THAT THE ADMINISTRATIVE AGENT, ANY LENDER OR THE L/C ISSUER MAY OTHERWISE HAVE TO BRING ANY ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AGAINST THE BORROWER OR ITS PROPERTIES IN THE COURTS OF ANY JURISDICTION.

          (c) WAIVER OF VENUE. EACH DEBTOR IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT IN ANY COURT REFERRED TO IN PARAGRAPH (B) OF THIS SECTION. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH ACTION OR PROCEEDING IN ANY SUCH COURT.

          (d) SERVICE OF PROCESS. EACH PARTY HERETO IRREVOCABLY CONSENTS TO SERVICE OF PROCESS IN THE MANNER PROVIDED FOR NOTICES IN SECTION 7.2. NOTHING IN THIS AGREEMENT WILL AFFECT THE RIGHT OF ANY PARTY HERETO TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY APPLICABLE LAW.

          (e) WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO

REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

     7.12 Additional Debtors. Each Subsidiary of the Borrower that is required to become a party to this Agreement after the date hereof pursuant to Section 6.12 of the Credit Agreement shall become a Debtor for all purposes of this Agreement upon execution and delivery by such Subsidiary of an instrument in the form of Annex I hereto.

     7.13 Termination; Releases.

          (a) This Security Agreement and the security interest created hereby shall terminate upon termination of the Aggregate Commitments and payment in full of all Obligations (other than (A) contingent indemnification obligations and (B) obligations and liabilities under Secured Cash Management Agreements and Secured Hedge Agreements as to which arrangements satisfactory to the applicable Cash Management Bank or Hedge Bank shall have been made) and the expiration or termination of all Letters of Credit (other than Letters of Credit as to which other arrangements satisfactory to the Administrative Agent and the L/C Issuer shall have been made), at which time the Administrative Agent shall execute and deliver to the Debtors or the Debtors’ designee, at the Debtors’ expense, all Uniform Commercial Code termination statements and similar documents which the Debtors shall reasonably request from time to time to evidence such termination. Any execution and delivery of termination statements or documents pursuant to this Section 7.13(a) shall be without recourse to or warranty by the Administrative Agent.

          (b) Any Debtor other than the Borrower shall automatically be released from its obligations hereunder and the security interest granted hereby in the Collateral of such Debtor shall be automatically released in the event that all the Equity Interests of such Debtor shall be sold, transferred or otherwise disposed of to a Person other than a Loan Party or a Subsidiary of a Loan Party in a transaction permitted by the Credit Agreement; provided that, to the extent required by the Credit Agreement, the Required Lenders or, if required by the terms of the Credit Agreement, such other requisite number of Lenders, shall have consented to such sale, transfer or other disposition and the terms of such consent did not provide otherwise. If any of the Collateral shall be sold, transferred or otherwise disposed of by any Debtor in a transaction permitted by the Credit Agreement the security interest created hereby in any Collateral that is so sold, transferred or otherwise disposed of shall automatically terminate and be released upon the closing of such sale, transfer or other disposition, and such Collateral shall be sold free and clear of the Lien and security interest created hereby; provided, however, that such security interest will continue to attach to all proceeds of such sales or other dispositions. In connection with any of the foregoing, the Administrative Agent shall deliver to the Debtors any Collateral then in its possession and shall execute and deliver to the Debtors or the Debtors’ designee, at the Debtors’ expense, all Uniform Commercial Code termination statements and similar documents that the Debtors shall reasonably request from time to time to evidence such termination.

Schedule 3.9 to Security Agreement

Annex I to the
Security Agreement

     This SUPPLEMENT NO. [     ] dated as of [     ] (this ” Supplement”), is delivered in connection with (a) the Security Agreement dated as of February __, 2011 (as amended, restated or otherwise modified from time to time, the “ Security Agreement”), among Basic Energy Services, Inc., a Delaware corporation (the ” Borrower”), certain subsidiaries of the Borrower (such subsidiaries together with the Borrower, the “ Debtors”) and Bank of America, N.A. (“ Bank of America”), as administrative agent (in such capacity, the “ Administrative Agent”) for the benefit of the holders of the Secured Obligations (as defined therein) and (b) the Guaranty dated as of February __, 2011 (as amended, restated or otherwise modified from time to time, the “ Guaranty”) made by the Debtors other than the Borrower (the “ Guarantors”) for the benefit of the Administrative Agent and the Lenders.

     A Reference is made to the Credit Agreement dated as of February __, 2011 (as amended, restated or otherwise modified from time to time, the “ Credit Agreement”), among the Borrower, the lenders from time to time party thereto (the “ Lenders”), the Administrative Agent and others. Pursuant to the Guaranty, the Guarantors have agreed to guarantee, among other things, the full payment and performance of all of the Borrower’s obligations under the Credit Agreement.
