Pledgor shall pledge hereunder, immediately upon its acquisition thereof, any and all additional shares of stock, other certificates or other instruments evidencing Collateral.

necessary or desirable by Secured Party to make each financing statement not seriously misleading. Pledgor shall not change its principal place of business, chief executive office or jurisdiction of organization unless it shall have given Secured Party thirty (30) days’ prior written notice thereof and shall have taken all action deemed necessary or desirable by Secured Party to cause its security interest in the Collateral to be protected and perfected with the priority required by this Agreement, including, without limitation, the delivery of a legal opinion satisfactory to the Secured Party as to the continued perfection and priority of the security interest hereby created.

ARTICLE IV.

Rights of Secured Party and Pledgor

Section 4.1. Power of Attorney. PLEDGOR HEREBY IRREVOCABLY CONSTITUTES AND APPOINTS SECURED PARTY AND ANY OFFICER OR AGENT THEREOF, WITH FULL POWER OF SUBSTITUTION, AS ITS TRUE AND LAWFUL ATTORNEY-IN-FACT WITH FULL IRREVOCABLE POWER AND AUTHORITY IN THE PLACE AND STEAD AND IN THE NAME OF PLEDGOR OR IN ITS OWN NAME, IN SECURED PARTY’S DISCRETION, TO TAKE, WHEN AN EVENT OF DEFAULT EXISTS, ANY AND ALL ACTION AND TO EXECUTE ANY AND ALL DOCUMENTS AND INSTRUMENTS WHICH MAY BE NECESSARY OR DESIRABLE TO ACCOMPLISH THE PURPOSES OF THIS AGREEMENT AND, WITHOUT LIMITING THE GENERALITY OF THE FOREGOING, HEREBY GIVES SECURED PARTY THE POWER AND RIGHT ON BEHALF OF PLEDGOR AND IN ITS OWN NAME TO DO, WHEN AN EVENT OF DEFAULT EXISTS, ANY OF THE FOLLOWING WITHOUT NOTICE TO OR THE CONSENT OF PLEDGOR:

(a) to demand, xxx for, collect, or receive in the name of Pledgor or in its own name, any money or property at any time payable or receivable on account of or in exchange for any of the Collateral and, in connection therewith, endorse checks, notes, drafts, acceptances, money orders, or any other instruments for the payment of money under the Collateral;

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

(c) (i) to direct account debtors and any other parties liable for any payment under any of the Collateral to make payment of any and all monies due and to become due thereunder directly to Secured Party or as Secured Party shall direct; (ii) 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; (iii) to sign and endorse any drafts, assignments, proxies, stock powers, verifications, notices, and other documents relating to the Collateral; (iv) to commence and prosecute any suit, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral or any part thereof and to enforce any other right in respect of any Collateral; (v) to participate in the defense of, or if Pledgor fails to defend, to defend any suit, action, or proceeding brought against Pledgor with respect to any Collateral; (vi) to settle, compromise, or adjust any suit, action, or proceeding described in clauses (iv) or (v) above, and, in connection therewith, to give such discharges or releases as Secured Party may deem appropriate; (vii) to exchange any of the Collateral for other property upon any merger, consolidation, reorganization, recapitalization, or other readjustment of the issuer thereof and, in connection therewith, deposit any of the Collateral with any committee, depositary, transfer agent, registrar, or other designated agency upon such terms as Secured Party may determine; and (viii) to sell, transfer, pledge, make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though Secured Party were the absolute owner thereof for all purposes, and to do, at Secured Party’s option and Pledgor’s expense, at any time, or from time to time, all acts and things which Secured Party deems necessary to protect, preserve, or realize upon the Collateral and Secured Party’s security interest therein.

THIS POWER OF ATTORNEY IS A POWER COUPLED WITH AN INTEREST AND SHALL BE IRREVOCABLE. Secured Party 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 Secured Party in this Agreement, and Secured Party shall not be liable for any failure to do so or any delay in doing so. Secured Party 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 in 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 Secured Party solely to protect, preserve and realize upon its security interest in the Collateral.

Section 4.2. Voting Rights. Unless an Event of Default exists, Pledgor shall be entitled to exercise any and all voting rights pertaining to the Collateral or any part thereof for any purpose not inconsistent with the terms of this Agreement, any Credit Facility or the Intercreditor Agreement. Secured Party shall execute and deliver to Pledgor all such proxies and other instruments as Pledgor may reasonably request for the purpose of enabling Pledgor to exercise the voting rights which it is entitled to exercise pursuant to this Section.

Section 4.3. Dividends. Unless an Event of Default exists, Pledgor shall be entitled to receive and retain any dividends paid on the Collateral in cash to the extent and only to the extent that such dividends are permitted by the Credit Facilities and applicable law.

Section 4.4. Secured Party’s Duty of Care. Other than the exercise of reasonable care in the physical custody of the Collateral while held by Secured Party hereunder, Secured Party shall have no responsibility for or obligation or duty with respect to all or any part of the Collateral or any matter or proceeding arising out of or relating thereto, including, without limitation, any obligation or duty to collect any sums due in respect thereof or to protect or preserve any rights against prior parties or any other rights pertaining thereto, it being understood and agreed that Pledgor shall be responsible for preservation of all rights in the Collateral. Without limiting the generality of the foregoing, Secured Party shall be conclusively deemed to have exercised reasonable care in the custody of the Collateral if Secured Party takes such action, for purposes of preserving rights in the Collateral, as Pledgor may reasonably request in writing, but no failure or omission or delay by Secured Party in complying with any such request by Pledgor, and no refusal by Secured Party to comply with any such request by Pledgor, shall be deemed to be a failure to exercise reasonable care.

ARTICLE V.

Default

Section 5.1. Rights and Remedies. If any Event of Default occurs, Secured Party shall have the following rights and remedies:

(a) In addition to all other rights and remedies granted to Secured Party in this Agreement , the Intercreditor Agreement and in any other instrument or agreement securing, evidencing, or relating to any of the obligations secured hereby, Secured Party shall have all of the rights and remedies of a secured party under the Uniform Commercial Code as adopted by the State of Texas or of a creditor with a lien or charge on the Collateral under the laws of the jurisdiction of the organization of the issuer of any of the Collateral. Without limiting the generality of the foregoing, Secured Party may (i) without demand or notice to Pledgor, collect, receive, or take possession of the Collateral or any part thereof, (ii) sell or otherwise dispose of the Collateral, or any part thereof, in one or more parcels at public or private sale or sales, at Secured Party’s offices or elsewhere, for cash, on credit, or for future delivery and/or (iii) bid and become a purchaser at any public (or private, to the extent permitted by applicable

law) sale free of any right or equity of redemption in Pledgor, which right or equity is hereby expressly waived and released by Pledgor. Upon the request of Secured Party, Pledgor shall assemble the Collateral not already in the possession of Secured Party and make it available to Secured Party at any place designated by Secured Party that is reasonably convenient to Pledgor and Secured Party. Pledgor agrees that Secured Party shall not be obligated to give more than ten (10) days prior written notice of the time and place of any public sale or of the time after which any private sale may take place and that such notice shall constitute reasonable notice of such matters; provided, however, if any of the Collateral threatens to decline speedily in value or is of a type customarily sold on a recognized market, Secured Party may sell or otherwise dispose of the Collateral without notification of any kind. Secured Party shall not be obligated to make any sale of the Collateral regardless of notice of sale having been given. Secured Party 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. Pledgor shall be liable for all reasonable expenses of retaking, holding, preparing for sale, or the like, and all reasonable attorneys’ fees and other expenses incurred by Secured Party in connection with the collection of the obligations secured hereby and the enforcement of Secured Party’s rights under this Agreement, all of which expenses and fees shall constitute additional obligations secured by this Agreement. Secured Party may apply the Collateral against the obligations secured hereby in such order and manner as Secured Party may determine in its discretion subject however, to the provisions of the Intercreditor Agreement. Pledgor shall remain liable for any deficiency if the proceeds of any sale or disposition of the Collateral are insufficient to pay the obligations secured hereby. Pledgor waives all rights of marshaling in respect of the Collateral.

(b) Secured Party may cause any or all of the Collateral held by it to be transferred into the name of Secured Party or the name or names of Secured Party's nominee or nominees.

(c) Secured Party may collect or receive all money or property at any time payable or receivable on account of or in exchange for any of the Collateral, but shall be under no obligation to do so.

(d) Secured Party shall have the right, but shall not be obligated to, exercise or cause to be exercised all voting, consensual and other powers of ownership pertaining to the Collateral, and Pledgor shall deliver to Secured Party, if requested by Secured Party, irrevocable proxies with respect to the Collateral in form satisfactory to Secured Party.

(e) Pledgor hereby acknowledges and confirms that Secured Party may be unable to effect a public sale of any or all of the Collateral by reason of certain prohibitions contained in the Securities Act of 1933, as amended, and applicable state or foreign securities laws and may be compelled to resort to one or more private sales thereof to a restricted group of purchasers who will be obligated to agree, among other things, to acquire any shares of the Collateral for their own respective accounts for investment and not with a view to distribution or resale thereof. Pledgor further acknowledges and confirms that any such private sale may result in prices or other terms less favorable to the seller than if such sale were a public sale and, notwithstanding such circumstances, agrees that any such private sale shall be deemed to have been made in a commercially reasonable manner, and Secured Party shall be under no obligation to take any steps in order to permit the Collateral to be sold at a public sale. Secured Party shall be under no obligation to delay a sale of any of the Collateral for any period of time necessary to permit any issuer thereof to register such Collateral for public sale under the Securities Act of 1933, as amended, or under applicable state or foreign securities laws.
