(a) General Remedies. During the existence of an Event of Default, the Lender shall have, in addition to the rights and remedies provided herein, in the Loan Documents, in any other documents relating to the Secured Obligations, or by Law (including, but not limited to, levy of attachment, garnishment and the rights and remedies set forth in the UCC of the jurisdiction applicable to the affected Collateral), the rights and remedies of a secured party under the UCC (regardless of whether the UCC is the law of the jurisdiction where the rights and remedies are asserted and regardless of whether the UCC applies to the affected Collateral), and further, the Lender may, with or without judicial process or the aid and assistance of others, (i) enter on any premises on which any of the Collateral may be located and, without resistance or interference by the Obligors, take possession of the Collateral, (ii) dispose of any Collateral on any such premises, (iii) require the Obligors to assemble and make available to the Lender at the expense of the Obligors any Collateral at any place and time designated by the Lender which is reasonably convenient to both parties, (iv) remove any Collateral from any such premises for the purpose of effecting sale or other disposition thereof, and/or (v) without demand and without advertisement, notice, hearing or process of law, all of which each of the Obligors hereby waives to the fullest extent permitted by Law, at any place and time or times, sell and deliver any or all Collateral held by or for it at public or private sale (which in the case of a private sale of Pledged Equity, shall be to a restricted group of purchasers who will be obligated 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), at any exchange or broker’s board or elsewhere, by one or more contracts, in one or more parcels, for Money, upon credit or otherwise, at such prices and upon such terms as the Lender deems advisable, in its sole discretion (subject to any and all mandatory legal requirements). Each Obligor acknowledges that any such private sale may be at prices and on terms less favorable to the seller than the prices and other terms which might have been obtained at a public sale and, notwithstanding the foregoing, agrees that such private sale shall be deemed to have been made in a commercially reasonable manner and, in the case of a sale of Pledged Equity, that the Lender shall have no obligation to delay sale of any such securities for the period of time necessary to permit the issuer of such securities to register such securities for public sale under the Securities Act of 1933. Neither the Lender’s compliance with applicable Law nor its disclaimer of warranties relating to the Collateral shall be considered to adversely affect the commercial reasonableness of any sale. To the extent the rights of notice cannot be legally waived hereunder, each Obligor agrees that any requirement of reasonable notice shall be met if such notice, specifying the place of any public sale or the time after which any private sale is to be made, is personally served on or mailed, postage prepaid, to the Borrower in accordance with the notice provisions of Section 10.07 of the Loan Agreement at least ten (10) days before the time of sale or other event giving rise to the requirement of such notice. The 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. Any sale hereunder may be conducted by an auctioneer or any officer or agent of Secured Party. The Collateral need not be present at any such sale.

(b) Remedies relating to Pledged Equity. Each Obligor further acknowledges and agrees that any offer to sell any Pledged Equity which has been (i) publicly advertised on a bona fide basis in a newspaper or other publication of general circulation in the financial community of New York, New York or Houston, Texas (to the extent that such offer may be advertised without prior registration under the Securities Act of 1933), or (ii) made privately in the manner described above shall be deemed to involve a “public sale” under the UCC, notwithstanding that such sale may not constitute a “public offering” under the Securities Act of 1933, and the Lender may, in such event, bid for the purchase of such securities. The Lender shall not be obligated to make any sale or other disposition of the Collateral regardless of notice having been given. To the extent permitted by applicable Law, any holder of Secured Obligations may be a purchaser at any such sale. To the extent permitted by applicable Law, each of the Obligors hereby waives all of its rights of redemption with respect to any such sale. Subject to the provisions of applicable Law, the Lender may postpone or cause the postponement of the sale of all or any portion of the Collateral by announcement at the time and place of such sale, and such sale may, without further notice, to the extent permitted by Law, be made at the time and place to which the sale was postponed, or the Lender may further postpone such sale by announcement made at such time and place.

(c) Remedies relating to Accounts. During the existence of an Event of Default, whether or not the Lender has exercised any or all of its rights and remedies hereunder, (i) each Obligor will promptly upon request of the Lender instruct all account debtors to remit all payments in respect of Accounts to a mailing location selected by the Lender and (ii) the Lender shall have the right to enforce any Obligor’s rights against its customers and account debtors, and the Lender or its designee may notify any Obligor’s customers and account debtors that the Accounts of such

Obligor have been assigned to the Lender or of the Lender’s security interest therein, and may (either in its own name or in the name of an Obligor or both) demand, collect (including without limitation by way of a lockbox arrangement), receive, take receipt for, sell, xxx for, compound, settle, compromise and give acquittance for any and all amounts due or to become due on any Account, and, in the Lender’s discretion, file any claim or take any other action or proceeding to protect and realize upon the security interest of the holders of the Secured Obligations in the Accounts. Each Obligor acknowledges and agrees that the Proceeds of its Accounts remitted to or on behalf of the Lender in accordance with the provisions hereof shall be solely for the Lender’s own convenience and that such Obligor shall not have any right, title or interest in such Accounts or in any such other amounts except as expressly provided herein. The Lender shall have no liability or responsibility to any Obligor for acceptance of a check, draft or other order for payment of money bearing the legend “payment in full” or words of similar import or any other restrictive legend or endorsement or be responsible for determining the correctness of any remittance. Furthermore, during the existence of an Event of Default, (i) the Lender shall have the right, but not the obligation, to make test verifications of the Accounts in any manner and through any medium that it reasonably considers advisable, and the Obligors shall furnish all such assistance and information as the Lender may require in connection with such test verifications, (ii) upon the Lender’s request and at the expense of the Obligors, the Obligors shall cause independent public accountants or others satisfactory to the Lender to furnish to the Lender reports showing reconciliations, aging and test verifications of, and trial balances for, the Accounts and (iii) the Lender in its own name or in the name of others may communicate with account debtors on the Accounts to verify with them to the Lender’s satisfaction the existence, amount and terms of any Accounts.

(d) Access. In addition to the rights and remedies hereunder, during the existence of an Event of Default, the Lender shall have the right to enter and remain upon the various premises of the Obligors without cost or charge to the Lender, and use the same, together with materials, supplies, books and records of the Obligors for the purpose of collecting and liquidating the Collateral, or for preparing for sale and conducting the sale of the Collateral, whether by foreclosure, auction or otherwise. In addition, the Lender may remove Collateral, or any part thereof, from such premises and/or any records with respect thereto, in order to effectively collect or liquidate such Collateral.

(e) Nonexclusive Nature of Remedies. Failure by the Lender to exercise any right, remedy or option under this Agreement, any other Loan Document, any other document relating to the Secured Obligations, or as provided by Law, or any delay by the Lender in exercising the same, shall not operate as a waiver of any such right, remedy or option. No waiver hereunder shall be effective unless it is in writing, signed by the party against whom such waiver is sought to be enforced and then only to the extent specifically stated, which in the case of the Lender shall only be granted as provided herein. To the extent permitted by Law, neither the Lender, nor any party acting as attorney for the Lender shall be liable hereunder for any acts or omissions or for any error of judgment or mistake of fact or law other than their gross negligence or willful misconduct hereunder. The rights, powers and remedies of Lender hereunder shall be in addition to all rights, powers and remedies given by statute, rule of law or any other Loan Document and are cumulative. The exercise of any one or more of the rights, powers and remedies provided herein shall not be construed as a waiver of any of the other rights, powers and remedies of Lender. Furthermore, regardless of whether or not the UCC is in effect in the jurisdiction where such rights, powers and remedies are asserted, Lender shall have the rights, powers and remedies of a secured party under the UCC, as amended from time to time.

(f) Retention of Collateral. In addition to the rights and remedies hereunder, the Lender may, in compliance with Sections 9.620 and 9.621 of the UCC or otherwise complying with the requirements of applicable Law of the relevant jurisdiction, accept or retain the Collateral in satisfaction of the Secured Obligations. Unless and until the Lender shall have provided such notices, however, the Lender shall not be deemed to have retained any Collateral in satisfaction of any Secured Obligations for any reason.

(g) Deficiency. In the event that the proceeds of any sale, collection or realization are insufficient to pay all amounts to which the Lender or the holders of the Secured Obligations are legally entitled, the Obligors shall be jointly and severally liable for the deficiency, together with interest thereon at the Default Rate, together with the costs of collection and the fees, charges and disbursements of counsel. Any surplus remaining after the full payment and satisfaction of the Secured Obligations shall be returned to the Obligors or to whomsoever a court of competent jurisdiction shall determine to be entitled thereto.

Section 8. Rights of the Lender.

(a) Power of Attorney. In addition to other powers of attorney contained herein, each Obligor hereby designates and appoints the Lender and each of its designees or agents, as attorney-in-fact of such Obligor, irrevocably and with power of substitution, with authority to take any or all of the following actions during the existence of an Event of Default:

(i) to demand, collect, settle, compromise, adjust, give discharges and releases, all as the Lender may reasonably determine;

(ii) to commence and prosecute any actions at any court for the purposes of collecting any Collateral and enforcing any other right in respect thereof;

(iii) to defend, settle or compromise any action brought and, in connection therewith, give such discharge or release as the Lender may deem reasonably appropriate;

(iv) to receive, open and dispose of mail addressed to an Obligor and endorse checks, notes, drafts, acceptances, money orders, bills of lading, warehouse receipts or other instruments or documents evidencing payment, shipment or storage of the goods giving rise to the Collateral of such Obligor on behalf of and in the name of such Obligor, or securing, or relating to such Collateral;

(v) to sell, assign, transfer, make any agreement in respect of, or otherwise deal with or exercise rights in respect of, any Collateral or the goods or services which have given rise thereto, as fully and completely as though the Lender were the absolute owner thereof for all purposes;

(vi) to adjust and settle claims under any insurance policy relating thereto;

(vii) to execute and deliver all assignments, conveyances, statements, financing statements, renewal financing statements, security agreements, affidavits, notices and other agreements, instruments and documents that the Lender may determine necessary in order to perfect and maintain the security interests and Liens granted in this Agreement and in order to fully consummate all of the transactions contemplated therein;

(viii) to institute any foreclosure proceedings that the Lender may deem appropriate;

(ix) to sign and endorse any drafts, assignments, proxies, stock powers, verifications, notices and other documents relating to the Collateral;

(x) to exchange any of the Pledged Equity or other property upon any merger, consolidation, reorganization, recapitalization or other readjustment of the issuer thereof and, in connection therewith, deposit any of the Pledged Equity with any committee, depository, transfer agent, registrar or other designated agency upon such terms as the Lender may reasonably deem appropriate;

(xi) to vote for a shareholder resolution, or to sign an instrument in writing, sanctioning the transfer of any or all of the Pledged Equity into the name of the Lender or one or more of the holders of the Secured Obligations or into the name of any transferee to whom the Pledged Equity or any part thereof may be sold pursuant to Section 7 hereof;

(xii) to pay or discharge taxes, Liens, security interests or other encumbrances levied or placed on or threatened against the Collateral;

(xiii) to direct any parties liable for any payment in connection with any of the Collateral to make payment of any and all monies due and to become due thereunder directly to the Lender or as the Lender shall direct;

(xiv) to receive payment of and receipt for any and all monies, claims, and other amounts due and to become due at any time in respect of or arising out of any Collateral; and

(xv) do and perform all such other acts and things as the Lender may reasonably deem to be necessary, proper or convenient in connection with the Collateral.

This power of attorney is a power coupled with an interest and shall be irrevocable until such time as the Secured Obligations arising under the Loan Documents have been paid in full and the Commitments have expired or been terminated. The Lender shall be under no duty to exercise or withhold the exercise of any of the rights, powers, privileges and options expressly or implicitly granted to the Lender in this Agreement, and shall not be liable for any failure to do so or any delay in doing so. The Lender shall not be liable for any act or omission or for any error of judgment or any mistake of fact or law in its individual capacity or its capacity as attorney-in-fact except acts or omissions resulting from its gross negligence or willful misconduct. This power of attorney is conferred on the Lender solely to protect, preserve and realize upon its security interest in the Collateral. This power of attorney shall not create any fiduciary obligations or relationship on the part of the Lender for the benefit of any Obligor.

(b) The Lender’s Duty of Care. Other than the exercise of reasonable care to assure the safe custody of the Collateral while being held by the Lender hereunder, the Lender shall have no duty or liability to preserve rights pertaining thereto, it being understood and agreed that the Obligors shall be responsible for preservation of all rights in the Collateral, and the Lender shall be relieved of all responsibility for the Collateral upon surrendering it or tendering the surrender of it to the Obligors. The Lender shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which the Lender accords its own property, which shall be no less than the treatment employed by a reasonable and prudent agent in the industry, it being understood that the Lender shall not have responsibility for taking any necessary steps to preserve rights against any parties with respect to any of the Collateral. In the event of a public or private sale of Collateral pursuant to Section 7 hereof, the Lender shall have no responsibility for (i) ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relating to any Collateral, whether or not the Lender has or is deemed to have knowledge of such matters, or (ii) taking any steps clean, repair or otherwise prepare the Collateral for sale.

(c) Liability with Respect to Accounts. Anything herein to the contrary notwithstanding, each of the Obligors shall remain liable under each of the Accounts to observe and perform all the conditions and obligations to be observed and performed by it thereunder, all in accordance with the terms of any agreement giving rise to each such Account. Neither the Lender nor any holder of Secured Obligations shall have any obligation or liability under any Account (or any agreement giving rise thereto) by reason of or arising out of this Agreement or the receipt by the Lender or any holder of Secured Obligations of any payment relating to such Account pursuant hereto, nor shall the Lender or any holder of Secured Obligations be obligated in any manner to perform any of the obligations of an Obligor under or pursuant to any Account (or any agreement giving rise thereto), to make any payment, to make any inquiry as to the nature or the sufficiency of any payment received by it or as to the sufficiency of any performance by any party under any Account (or any agreement giving rise thereto), to present or file any claim, to take any action to enforce any performance or to collect the payment of any amounts which may have been assigned to it or to which it may be entitled at any time or times.

(d) Voting and Payment Rights in Respect of the Pledged Equity.

(i) So long as no Event of Default shall exist, each Obligor may (A) exercise any and all voting and other consensual rights pertaining to the Pledged Equity of such Obligor or any part thereof for any purpose not inconsistent with the terms of this Agreement or the Loan Agreement and (B) receive and retain any and all dividends (other than stock dividends and other dividends constituting Collateral which are addressed hereinabove), principal or interest paid in respect of the Pledged Equity to the extent they are allowed under the Loan Agreement; and

(ii) During the existence of an Event of Default, (A) all rights of an Obligor to exercise the voting and other consensual rights which it would otherwise be entitled to exercise pursuant to clause (i)(A) above shall cease and all such rights shall thereupon become vested in the Lender which shall then have the sole right to exercise such voting and other consensual rights, (B) all rights of an Obligor to receive the dividends, principal and interest payments which it would otherwise be authorized to receive and retain pursuant to clause (i)(B) above shall

cease and all such rights shall thereupon be vested in the Lender which shall then have the sole right to receive and hold as Collateral such dividends, principal and interest payments, and (C) all dividends, principal and interest payments which are received by an Obligor contrary to the provisions of clause (ii)(B) above shall be received in trust for the benefit of the Lender, shall be segregated from other property or funds of such Obligor, and shall be forthwith paid over to the Lender as Collateral in the exact form received, to be held by the Lender as Collateral and as further collateral security for the Secured Obligations.

(e) Releases of Collateral. (i) If any Collateral shall be sold, transferred or otherwise disposed of by any Obligor in a transaction permitted by the Loan Agreement, then the Lender, at the request and sole expense of such Obligor, shall promptly execute and deliver to such Obligor all releases and other documents, and take such other action, reasonably necessary for the release of the Liens created hereby or by any other Collateral Document on such Collateral. (ii) The Lender may release any of the Pledged Equity from this Agreement or may substitute any of the Pledged Equity for other Pledged Equity without altering, varying or diminishing in any way the force, effect, lien, pledge or security interest of this Agreement as to any Pledged Equity not expressly released or substituted, and this Agreement shall continue as a first priority lien on all Pledged Equity not expressly released or substituted.

Section 9. Application of Proceeds. Upon the acceleration of the Obligations pursuant to Section 8.02 of the Loan Agreement, any payments in respect of the Secured Obligations and any proceeds of the Collateral, when received by the Lender or any holder of the Secured Obligations in Money, will be applied in reduction of the Secured Obligations in the order set forth in Section 8.03 of the Loan Agreement.

Section 10. Continuing Agreement.

(a) This Agreement shall remain in full force and effect until such time as the Secured Obligations arising under the Loan Documents have been paid in full and the Commitments have expired or been terminated, at which time this Agreement shall be automatically terminated and the Lender shall, upon the request and at the expense of the Obligors, forthwith release all of its Liens and security interests hereunder and shall execute and deliver all UCC termination statements and/or other documents reasonably requested by the Obligors evidencing such termination.

(b) This Agreement shall continue to be effective or be automatically reinstated, as the case may be, if at any time payment, in whole or in part, of any of the Secured Obligations is rescinded or must otherwise be restored or returned by the Lender or any holder of the Secured Obligations as a preference, fraudulent conveyance or otherwise under any Debtor Relief Law, all as though such payment had not been made; provided that in the event payment of all or any part of the Secured Obligations is rescinded or must be restored or returned, all reasonable costs and expenses (including without limitation any reasonable legal fees and disbursements) incurred by the Lender or any holder of the Secured Obligations in defending and enforcing such reinstatement shall be deemed to be included as a part of the Secured Obligations.

Section 11. Amendments; Waivers; Modifications, etc. This Agreement and the provisions hereof may not be amended, waived, modified, changed, discharged or terminated

except as set forth in Section 10.10 of the Loan Agreement; provided that any update or revision to Schedule 2(c) hereof delivered by any Obligor shall not constitute an amendment for purposes of this Section 11 or Section 10.10 of the Loan Agreement.

Section 12. Successors in Interest. This Agreement shall be binding upon each Obligor, its successors and assigns and shall inure, together with the rights and remedies of the Lender its successors and permitted assigns.

Section 13. Notices. All notices required or permitted to be given under this Agreement shall be in conformance with Section 10.07 of the Loan Agreement.

Section 14. Counterparts. This Agreement may be executed in any number of counterparts, each of which where so executed and delivered shall be an original, but all of which shall constitute one and the same instrument. It shall not be necessary in making proof of this Agreement to produce or account for more than one such counterpart.

Section 15. Headings. The headings of the sections hereof are provided for convenience only and shall not in any way affect the meaning or construction of any provision of this Agreement.

Section 17. Severability. If any provision of any of the Agreement is determined to be illegal, invalid or unenforceable, such provision shall be fully severable and the remaining provisions shall remain in full force and effect and shall be construed without giving effect to the illegal, invalid or unenforceable provisions.

Section 18. Entirety. This Agreement, the other Loan Documents and the other documents relating to the Secured Obligations represent the entire agreement of the parties hereto and thereto, and supersede all prior agreements and understandings, oral or written, if any, including any commitment letters or correspondence relating to the Loan Documents, any other documents relating to the Secured Obligations, or the transactions contemplated herein and therein.

Section 19. Other Security. To the extent that any of the Secured Obligations are now or hereafter secured by property other than the Collateral (including, without limitation, real property and securities owned by an Obligor), or by a guarantee, endorsement or property of any other Person, then the Lender shall have the right to proceed against such other property, guarantee or endorsement during the existence of any Event of Default, and the Lender shall have the right, in its sole discretion, to determine which rights, security, Liens or remedies the Lender shall at any time pursue, relinquish, subordinate, modify or take with respect thereto, without in any way modifying or affecting any of them or the Secured Obligations or any of the rights of the Lender or the holders of the Secured Obligations under this Agreement, under any other of the Loan Documents or under any other document relating to the Secured Obligations.

Section 20. Joinder. At any time after the date of this Agreement, one or more additional Persons may become party hereto by executing and delivering to the Lender a Joinder Agreement.
