In the case of any Pledged Membership Interests constituting such Collateral, all of such Pledged Membership Interests are duly authorized and validly issued, fully paid, and non-assessable, and constitute all of the Membership Interests of each Pledged Membership Interest Company.

SECTION 3.1.6. COMPLIANCE WITH LAWS. The Pledgor is in compliance with the requirements of all applicable laws, rules, regulations and orders of every governmental authority, the non-compliance with which might materially adversely affect the business, properties, assets, operations, condition (financial or otherwise) or prospects of the Pledgor or the value of the Collateral or the worth of the Collateral as collateral security. SECTION 3.1.7. NOT SECURITES. The Collateral hereunder is not a "Security" under Article 8 of the UCC. ARTICLE IV COVENANTS SECTION 4.1. PROTECT COLLATERAL; FURTHER ASSURANCES, ETC.

The Agent agrees that unless an Event of Default shall have occurred and be continuing and the Agent shall have given the notice referred to in clause (b) of SECTION 4.4, the Pledgor shall have the exclusive voting power with respect to any shares of capital stock or membership interests (including any of the Pledged Shares or Pledged Membership Interests) constituting Collateral and the Agent shall, upon the written request of the Pledgor, promptly deliver such proxies and other documents, if any, as shall be reasonably 7 requested by the Pledgor which are necessary to allow the Pledgor to exercise voting power with respect to any such share of capital stock or membership interests (including any of the Pledged Shares or Pledged Membership Interests) constituting Collateral; provided, however, that no vote shall be cast, or consent, waiver or ratification given, or action taken by the Pledgor that would impair any Collateral or be inconsistent with or violate any provision of the Credit Agreement or any other Loan Document (including this Pledge Agreement). SECTION 4.5. ADDITIONAL UNDERTAKINGS.

SECTION 5.3. AGENT HAS NO DUTY. The powers conferred on the Agent hereunder are solely to protect its interest (on behalf of the Lender Parties) in the Collateral and shall not impose any duty on it to exercise any such powers. Except for reasonable care of any Collateral in its possession and the accounting for moneys actually received by it hereunder, the Agent shall have no duty as to any Collateral or responsibility for (a) ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Pledged Property, whether or not the Agent has or is deemed to have knowledge of such matters, or (b) taking any necessary steps to preserve rights against prior parties or any other rights pertaining to any Collateral. SECTION 5.4. REASONABLE CARE. The Agent is required to exercise reasonable care in the custody and preservation of any of the Collateral in its possession; provided, however, the Agent shall be deemed to have exercised reasonable care in the custody and preservation of any of the Collateral, if it takes such action for that purpose as the Pledgor reasonably requests in writing at times other than upon the occurrence and during the continuance of any Event of Default, but failure of the Agent to comply with any such request at any time shall not in itself be deemed a failure to exercise reasonable care. ARTICLE VI REMEDIES SECTION 6.1. CERTAIN REMEDIES. If any Event of Default shall have occurred and be continuing: (a) The Agent may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party on default under the UCC (whether or not the UCC applies to the affected Collateral) and also may, without notice except as specified below, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any of the Agent's offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as the Agent may deem commercially reasonable. The Pledgor agrees that, to the extent notice of sale shall be required by law, at least ten days' prior notice to the Pledgor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Agent 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.

SECTION 6.2. COMPLIANCE WITH RESTRICTIONS. The Pledgor agrees that in any sale of any of the Collateral whenever an Event of Default shall have occurred and be continuing, the Agent is hereby authorized to comply with any limitation or restriction in connection with such sale as it may be advised by counsel is necessary in order to avoid any violation of applicable law (including compliance with such procedures as may restrict the number of prospective bidders and purchasers, require that such prospective bidders and purchasers have certain qualifications, and restrict such prospective bidders and 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 such Collateral), or in order to obtain any required approval of the sale or of the purchaser by any governmental regulatory authority or official, and the Pledgor further agrees that such compliance shall not result in such sale being considered or deemed not to have been made in a commercially reasonable manner, nor shall the Agent be liable nor accountable to the Pledgor for any discount allowed by the reason of the fact that such Collateral is sold in compliance with any such limitation or restriction. SECTION 6.3. APPLICATION OF PROCEEDS. All cash proceeds received by the Agent in respect of any sale of, collection from, or other realization upon, all or any part of the Collateral may, in the discretion of the Agent, be held by the Agent as additional collateral security for, or then or at any time thereafter be applied (after payment of any amounts payable to the Agent pursuant to Section 10.3 of either Credit Agreement and SECTION 6.4) in whole or in part by the Agent against, all or any part of the Obligations in such order as the Agent shall elect. Any surplus of such cash or cash proceeds held by the Agent and remaining after final payment in full of all the Obligations, and the termination of all Commitments, shall be paid over to the Pledgor or to whomsoever may be lawfully entitled to receive such surplus. SECTION 6.4. INDEMNITY AND EXPENSES. The Pledgor hereby indemnifies and holds harmless the Agent from and against any and all claims, losses and liabilities arising out of or resulting from this Pledge Agreement (including enforcement of this Pledge Agreement), except claims, losses or liabilities resulting from the Agent's gross negligence or wilful misconduct. Upon demand, the Pledgor will pay to the Agent the amount of any and all reasonable expenses, including the reasonable fees and disbursements of its counsel (including the reasonable allocated cost of internal legal services and all disbursements of internal counsel) and of any experts and agents, which the Agent may incur in connection with: (a) the administration of this Pledge Agreement, the Credit Agreement and each other Loan Document; 10 (b) the custody, preservation, use or operation of, or the sale of, collection from or other realization upon, any of the Collateral; (c) the exercise or enforcement of any of the rights of the Agent hereunder; or (d) the failure by the Pledgor to perform or observe any of the provisions hereof.
