Subject to the terms and conditions of this Agreement, each Loan under this Section shall be made available to Debtor by depositing

(b)    Additional Documents. To secure full and complete payment and performance of the Indebtedness, Debtor shall execute and deliver or cause to be executed and delivered all of the Loan Documents reasonably required by Lender covering the Collateral. Debtor shall execute and cause to be executed such further documents and instruments, as Lender, in its reasonable discretion, deems necessary or desirable to create, evidence, preserve, and perfect its liens and security interests in the Collateral. In the event any of the Loan Documents evidencing or securing the Indebtedness misrepresents or inaccurately reflects the correct terms and/or provisions of the Indebtedness, Debtor shall upon request by Lender and in order to correct such mistake, execute such new documents or initial corrected, original documents as Lender may deem necessary to remedy said errors or mistakes. Debtor shall execute such other documents as Lender shall deem reasonably necessary to correct any defects or deficiencies in the Loan Documents. Debtor’s failure to execute such documents as requested shall constitute an Event of Default under this Agreement.

(c)    Setoff. If an Event of Default shall have occurred and be continuing, Lender shall have the right to set off and apply against the Indebtedness in such manner as Lender may determine, at any time and without notice to Debtor, any and all deposits (general or special, time or demand, provisional or final) or other sums at any time credited by or owing from Lender to Debtor whether or not the Indebtedness is then due. The rights and remedies of Lender hereunder are in addition to any other rights and remedies (including, without limitation, other rights of setoff) which Lender may have.

(d)    Satisfaction of Indebtedness.

retain the security interests in the Collateral granted under the Loan Documents and the ability to exercise all rights and remedies available to Lender under the Loan Documents and applicable laws.

(e)    Additional Collateral.

(i)If at the close of business on any Business Day (x) the outstanding principal balance of the Loans equals or exceeds (y) an amount equal to the Fair Market Value of Eligible Collateral pledged as Collateral multiplied by the Default/Margin Call Percentage, Lender shall give notice to Debtor of the same, and, prior to the close of business on the THIRD (3^rd) Business Day after the occurrence of such event (such date, being a “Call Date”), Debtor shall (1) prepay a portion of the Loans, and/or (2) pledge to Lender additional Eligible Collateral sufficient to cause the Borrowing Base Deficiency to be cured. If at the close of business on such Call Date, Debtor has failed to comply with this clause (i), Lender may, without notice to Debtor or any other action, immediately liquidate all or any portion of the Collateral and apply the same to satisfy the Indebtedness, in Lender’s sole discretion.

(ii)Notwithstanding the foregoing, if at the close of business on any Business Day (x) the outstanding principal balance of the Loans equals or exceeds (y) an amount equal to the Fair Market Value of Eligible Collateral pledged as Collateral multiplied by the Liquidation Percentage, Lender may, without notice to Debtor or any other action, immediately liquidate all or any portion of the Collateral and apply the same to satisfy the Indebtedness, in Lender’s sole discretion.

Debtor will cause Securities Intermediary to send to Lender a complete and accurate copy of every statement, confirmation, notice or other communication concerning the Collateral Account that the Securities Intermediary sends to Debtor. Any confirmation or statement of account that Lender may (but need not) issue will conclusively establish delivery of Eligible Collateral to Lender.

(v)Debtor will comply with the securities laws with respect to Debtor’s ownership of Collateral.

Debtor will notify Lender immediately of any development or occurrence which to Debtor’s knowledge would render any Collateral not readily saleable under the securities laws.

(a)    Remedies. Upon the occurrence of any one or more of the foregoing Events of Default, (i) the entire unpaid balance of principal of the Note, together with all accrued but unpaid interest thereon, and all other Indebtedness owing to Lender by Debtor at such time shall, at the option of Lender, become immediately due and payable without further notice, demand, presentation, notice of dishonor, notice of intent to accelerate, notice of acceleration, protest or notice of protest of any kind, all of which are expressly waived by Debtor, and (ii) Lender may, at its option, cease further advances under the Note and this Agreement; provided, however, concurrently and automatically with the occurrence of an Event of Default under Subsection 10(d) further advances under the Loan Documents shall automatically cease, the Indebtedness at such time shall, without any action by Lender, become due and payable, without further notice, demand, presentation, notice of dishonor, notice of acceleration, notice of intent to accelerate, protest or notice of protest of any kind, all of which are expressly waived by Debtor. All rights and remedies of Lender set forth in this Agreement and in any of the other Loan Documents may also be exercised by Lender, at its option to be exercised in its sole discretion, upon the occurrence of an Event of Default, and not in substitution or diminution of any rights now or hereafter held by Lender under the terms of any other agreement.

(b)    Other Remedies. Lender may from time to time at its discretion, without limitation and without notice except as expressly provided in any of the Loan Documents:

(i)Sell, or instruct Securities Intermediary or any agent or broker to sell, all or any part of the Collateral in a public or private sale, direct any agent, Securities Intermediary or broker to liquidate all or any part of the Collateral Account and deliver all proceeds thereof to Secured Party, and apply all proceeds to the payment of any or all of the Indebtedness in such order and manner as Secured Party shall, in its discretion, choose or hold such proceeds as additional Collateral for the Indebtedness.

(ii)Exercise in respect of the Collateral all the rights and remedies of a secured party under the Code (whether or not the Code applies to the affected Collateral);

(iii)Require Debtor to, and Debtor hereby agrees that it will at its expense and upon request of Lender, assemble the Collateral as directed by Lender and make it available to Lender at a place to be designated by Lender which is reasonably convenient to both parties;

(iv)Reduce its claim to judgment or foreclose or otherwise enforce, in whole or in part, the security interest granted hereunder by any available judicial procedure;

(v)Sell or otherwise dispose of, at its office, on the premises of Debtor or elsewhere, the Collateral, as a unit or in parcels, by public or private proceedings, and by way of one or more contracts (it being agreed that the sale or other disposition of any part of the Collateral shall not exhaust Lender’s power of sale, but sales or other dispositions may be made from time to time until all of the Collateral has been sold or disposed of or until the Indebtedness has been paid and performed in full), and at any such sale or other disposition it shall not be necessary to exhibit any of the Collateral;

(vi)Buy the Collateral, or any portion thereof, at any public sale;

(vii)Buy the Collateral, or any portion thereof, at any private sale if the Collateral is of a type customarily sold in a recognized market or is of a type which is the subject of widely distributed standard price quotations;

(viii)Apply for the appointment of a receiver for the Collateral, and Debtor hereby consents to any such appointment; and

(ix) At its option, retain the Collateral in satisfaction of the Indebtedness whenever the circumstances are such that Lender is entitled to do so under the Code or otherwise.

Debtor agrees that in the event Debtor is entitled to receive any notice under the Code, as it exists in the state governing any such notice, of the sale or other disposition of any Collateral, reasonable notice shall be deemed given when such notice is deposited in a depository receptacle under the care and custody of the United States Postal Service, postage prepaid, at Debtor’s address set forth on the signature page hereof, TEN (10) days prior to the date of any public sale, or after which a private sale, of any of such Collateral is to be held. Lender shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. Lender may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. If permitted by applicable law, any Collateral which is sold on a recognized market may be sold immediately by Lender without prior notice to Debtor. At any sale or disposition of Collateral, Lender may (to the extent permitted by applicable law) (i) purchase all or any part thereof free from any right of redemption by Debtor or any other Person guaranteeing the Indebtedness, which right is hereby waived and released, (ii) restrict the number of prospective bidders or purchasers and/or further restrict such prospective bidders or purchasers to Persons who will represent and agree that they are purchasing for their own account, for investment and not with a view to the distribution or resale of the Collateral, and (iii) otherwise require that such sale be conducted subject to restrictions as to such other matters as Lender may deem necessary in order that such sale may be effected in such manner as to comply with all applicable state and federal securities and other laws. Lender shall not be obligated to make any sale or other disposition of any Collateral if it shall determine not to do so, regardless of the fact that notice of sale or other disposition of such Collateral shall have been given. Debtor hereby acknowledges that (i) notwithstanding that a higher price might be obtained for the Collateral at a public sale than at a private sale or sales, the making of a public sale of the Collateral may be subject to registration requirements under applicable securities laws and other legal restrictions, compliance with which would require such actions on the part of such Credit Party, would entail such expenses and would subject Lender or any underwriter through whom the Collateral may be sold or any controlling person of any of the foregoing to such liabilities, as would make a public sale of the Collateral impractical, and accordingly, Debtor hereby agrees that private sales made by Debtor in good faith in accordance with the provisions of this Agreement may be at prices and on other terms less favorable to the seller than if the Collateral were sold at a public sale, and that Lender shall not have any obligation to take any steps in order to permit the Collateral to be sold at a public sale, such a private sale being considered or deemed to be a sale in a commercially reasonable manner; (ii) any private sale of the Collateral may be subject to compliance with federal and state securities and/or other laws; and (iii) Lender is hereby authorized to comply with any limitation or restriction in connection with such sale that may be necessary in order to avoid any violation of applicable law or in order to obtain any required approval of the purchaser(s) by any Governmental Authority or officer or court.

(c)    Application of Proceeds. If any Event of Default shall have occurred, Lender may at its discretion apply or use any cash held by Lender as Collateral, and any cash proceeds received by Lender in respect of any sale or other disposition of, collection from, or other realization upon, all or any part of the Collateral as follows in such order and manner as Lender may elect:

(i)to the repayment or reimbursement of the reasonable costs and expenses (including, without limitation, reasonable attorneys’ fees and expenses) incurred by Lender in connection with (1) the administration of the Loan Documents, (2) the custody, preservation, use or operation of, or the sale of, collection from, or other realization upon, the Collateral, and (3) the exercise or enforcement of any of the rights and remedies of Lender hereunder;

(ii)to the payment or other satisfaction of any liens and other encumbrances upon the Collateral;

(iii)to the satisfaction of the Indebtedness;

(iv)by holding such cash and proceeds as Collateral;

(v)to the payment of any other amounts required by applicable law; and

(vi)by delivery to Debtor or any other party lawfully entitled to receive such cash or proceeds whether by direction of a court of competent jurisdiction or otherwise.

(d)    Deficiency. In the event that the proceeds of any sale of, collection from, or other realization upon, all or any part of the Collateral by Lender are insufficient to pay all amounts to which Lender is legally entitled, Debtor (unless otherwise provided) shall be liable for the deficiency, together with interest thereon as provided in the Loan Documents.

(e)    Non‑Judicial Remedies. In granting to Lender the power to enforce its rights hereunder without prior judicial process or judicial hearing, Debtor expressly waives, renounces and knowingly relinquishes any legal right which might otherwise require Lender to enforce its rights by judicial process. Debtor recognizes and concedes that non‑judicial remedies are consistent with the usage of trade, are responsive to commercial necessity and are the result of a bargain at arm’s length. Nothing herein is intended to prevent Lender or Debtor from resorting to judicial process at either party’s option.

(f)    No Waiver; Cumulative Remedies. No failure on the part of Lender to exercise, no delay in exercising and no course of dealing with respect to, any right, power, or privilege under this Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power, or privilege under this Agreement preclude any other or further exercise thereof or the exercise of any other right, power, or privilege. The rights and remedies provided for in this Agreement and the other Loan Documents are cumulative and not exclusive of any rights and remedies provided by law.

(g)    Equitable Relief. Debtor recognizes that in the event Debtor fails to pay, perform, observe, or discharge any or all of the Indebtedness, any remedy at law may prove to be inadequate relief to Lender. Debtor therefore agrees that Lender, if Lender so requests, shall be entitled to temporary and permanent injunctive relief in any such case without the necessity of proving actual damages.

12.    Indemnity. Debtor hereby indemnifies and agrees to hold harmless Lender, and its officers, directors, employees, agents and representatives (each an “Indemnified Person”) from and against any and all liabilities, obligations, claims, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature (collectively, the “Claims”) which may be imposed on, incurred by, or asserted against, any Indemnified Person arising in connection with the Loan Documents, the Indebtedness or the Collateral (including without limitation, the enforcement of the Loan Documents and the defense of any Indemnified Person’s actions and/or inactions in connection with the Loan Documents). WITHOUT LIMITATION, THE FOREGOING INDEMNITIES SHALL APPLY TO EACH INDEMNIFIED PERSON WITH RESPECT TO ANY CLAIMS WHICH IN WHOLE OR IN PART ARE CAUSED BY OR ARISE OUT OF THE NEGLIGENCE OF SUCH AND/OR ANY OTHER INDEMNIFIED PERSON, EXCEPT TO THE LIMITED EXTENT THE CLAIMS AGAINST AN INDEMNIFIED PERSON ARE PROXIMATELY CAUSED BY SUCH INDEMNIFIED PERSON’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. If Debtor or any third party ever alleges such gross negligence or willful misconduct by any Indemnified Person, the indemnification provided for in this Section shall nonetheless be paid upon demand, subject to later adjustment or reimbursement, until such time as (a) a court of competent jurisdiction enters a final judgment as to the extent and effect of the alleged gross negligence or willful misconduct, or (b) Lender expressly agrees in writing with Debtor that such Claim is proximately caused by such Indemnified Person’s gross negligence or willful misconduct. The indemnification provided for in this Section shall survive the termination of this Agreement and shall extend and continue to benefit each individual or entity that is or has at any time been an Indemnified Person hereunder.

13.    Limitation of Liability and Releases. Neither Lender nor any affiliate, officer, director, employee, attorney, or agent of Lender shall have any liability with respect to, and Debtor hereby waives, releases, and agrees not to sue any of them upon, any claim for any special, indirect, incidental, or consequential damages suffered or incurred by Debtor in connection with, arising out of, or in any way related to, this Agreement or any of the other Loan Documents, or any of the transactions contemplated by this Agreement or any of the other Loan Documents. Debtor hereby waives, releases, and agrees not to sue Lender or any of Lender’s affiliates, officers, directors, employees, attorneys, or agents for punitive damages in respect of any claim in connection with, arising out of, or in any way related to, this Agreement

or any of the other Loan Documents, or any of the transactions contemplated by this Agreement or any of the other Loan Documents.

14.    No Duty. All attorneys, accountants, appraisers, and other professional Persons and consultants retained by Lender shall have the right to act exclusively in the interest of Lender and shall have no duty of disclosure, duty of loyalty, duty of care, or other duty or obligation of any type or nature whatsoever to Debtor or any of Debtor’s equity holders or any other Person. Documents in connection with the transactions contemplated hereunder have been prepared by GARDERE WYNNE SEWELL LLP (“Lender’s Counsel”). Debtor acknowledges and understands that Lender’s Counsel is acting solely as counsel to Lender in connection with the transaction contemplated herein, is not representing Debtor in connection therewith, and has not, in any manner, undertaken to assist or render legal advice to Debtor with respect to this transaction. Debtor has been advised to seek other legal counsel to represent its interests in connection with the transactions contemplated herein.

15.    Lender Not Fiduciary. The relationship between Debtor and Lender is solely that of debtor and creditor, and Lender has no fiduciary or other special relationship with Debtor, and no term or condition of any of the Loan Documents shall be construed so as to deem the relationship between Debtor and Lender to be other than that of debtor and creditor.

16.    Waiver and Agreement. Neither the failure nor any delay on the part of Lender to exercise any right, power or privilege herein or under any of the other Loan Documents shall operate as a waiver thereof, nor shall any single or partial exercise of such right, power or privilege preclude any other or further exercise thereof or the exercise of any other right, power or privilege. No waiver of any provision in this Agreement or in any of the other Loan Documents and no departure by Debtor therefrom shall be effective unless the same shall be in writing and signed by Lender, and then shall be effective only in the specific instance and for the purpose for which given and to the extent specified in such writing. No modification or amendment to this Agreement or to any of the other Loan Documents shall be valid or effective unless the same is signed by the party against whom it is sought to be enforced.

17.    Benefits. This Agreement shall be binding upon and inure to the benefit of Lender and Debtor, and their respective successors and assigns, provided, however, that Debtor may not, without the prior written consent of Lender, assign any rights, powers, duties or obligations under this Agreement or any of the other Loan Documents.

18.    Notices. All notices, requests, demands or other communications required or permitted to be given pursuant to this Agreement shall be in writing and given by (a) personal delivery, (b) expedited delivery service with proof of delivery, or (c) United States mail, postage prepaid, registered or certified mail, return receipt requested, sent to the intended addressee at the address set forth on the signature page hereof and shall be deemed to have been received either, in the case of personal delivery, as of the time of personal delivery, in the case of expedited delivery service, as of the time of the expedited delivery and in the manner provided herein, or in the case of mail, upon the THIRD (3^rd) day after deposit in a depository receptacle under the care and custody of the United States Postal Service. Any party shall have the right to change its address for notice hereunder to any other location within the continental United States by notice to the other party of such new address.

19.    Construction; Venue; Service of Process. The Loan Documents have been executed and delivered in the State of Texas, shall be governed by and construed in accordance with the laws of the State of Texas, and shall be performable by the parties hereto in Dallas, Dallas County, Texas (the “Venue Site”). Any action or proceeding against Debtor under or in connection with any of the Loan Documents may be brought in any state or federal court within the Venue Site. Debtor hereby irrevocably (a) submits to the nonexclusive jurisdiction of such courts, and (b) waives any objection it may now or hereafter have as to the venue of any such action or proceeding brought in any such court or that any such court is an inconvenient forum. Debtor agrees that service of process upon it may be made by certified or registered mail, return receipt requested, at its address specified or determined in accordance with the provisions this Agreement. Nothing in any of the other Loan Documents shall affect the right of Lender to serve process in any other manner permitted by law or shall limit the right of Lender to bring any action or proceeding against Debtor or with respect to any of its property in courts in other jurisdictions. Any action or proceeding by Debtor against Lender shall be brought only in a court located in the Venue Site.

20.    Invalid Provisions. If any provision of the Loan Documents is held to be illegal, invalid or unenforceable under present or future laws, such provision shall be fully severable and the remaining provisions of the

Loan Documents shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable provision or by its severance.

21.    Expenses. Debtor shall pay all reasonable costs and expenses (including, without limitation, reasonable attorneys’ fees) in connection with (a) the drafting and execution of the Loan Documents and the transactions contemplated therein, (b) any action required in the course of administration of the indebtedness and obligations evidenced by the Loan Documents, and (c) any action in the enforcement of Lender’s rights upon the occurrence of an Event of Default.

22.    Participation of the Loans. Debtor agrees that Lender may, at its option, sell interests in the Loans and its rights under this Agreement to a financial institution or institutions and, in connection with each such sale, Lender may disclose any financial and other information available to Lender concerning Debtor to each perspective purchaser subject to obtaining a confidentiality agreement with each prospective purchaser prior to disclosing Debtor’s confidential information.

23.    Conflicts. Except as otherwise expressly provided in the Note, in the event any term or provision of this Agreement is inconsistent with or conflicts with any provision of the other Loan Documents, the terms and provisions contained in this Agreement shall be controlling.

24.    Counterparts. The Loan Documents may be separately executed in any number of counterparts, each of which shall be an original, but all of which, taken together, shall be deemed to constitute one and the same instrument.

25.    Survival. All representations and warranties made in the Loan Documents or in any document, statement, or certificate furnished in connection with this Agreement shall survive the execution and delivery of the Loan Documents, and no investigation by Lender or any closing shall affect the representations and warranties or the right of Lender to rely upon them.

26.    Waiver of Right to Trial by Jury. THE PARTIES HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, SUIT, PROCEEDING, OR COUNTERCLAIM THAT RELATES TO OR ARISES OUT OF THE LOAN DOCUMENTS OR THE ACTS OR FAILURE TO ACT OF OR BY LENDER IN THE ENFORCEMENT OF ANY OF THE TERMS OR PROVISIONS OF THE LOAN DOCUMENTS.

27.    Patriot Act Notice. Lender hereby notifies Debtor that pursuant to the requirements of Section 326 of the USA Patriot Act of 2001, 31 U.S.C. § 5318 (the “Act”), that Lender is required to obtain, verify and record information that identifies Debtor, which information includes the name and address of Debtor and other information that will allow such Lender to identify Debtor in accordance with the Act.

28.    Regulation B—Notice of Joint Intent. If Debtor is more than one Person, Federal Regulation B (Equal Credit Opportunity Act) requires Lender to obtain evidence of Debtor’s intention to apply for joint credit. Debtor’s signature below shall evidence such intent. Debtor’s intent shall apply to future related extensions of joint credit and joint guaranty.

29.    Notice of Final Agreement. It is the intention of Debtor and Lender that the following NOTICE OF FINAL AGREEMENT be incorporated by reference into each of the Loan Documents (as the same may be amended, modified or restated from time to time). Debtor and Lender warrant and represent that the entire agreement made and existing by or between Debtor and Lender with respect to the Loans is and shall be contained within the Loan Documents, and that no agreements or promises exist or shall exist by or among, Debtor and Lender that are not reflected in the Loan Documents.
