Section 4.1 Generally. Grantor shall (a) except for the security interest created by this Agreement, not create or suffer to exist any Lien upon or with respect to any of the Collateral, except Liens permitted under the Credit Agreement; (b) not use or permit any Collateral to be used

(i) change its state of incorporation or the location of its chief executive office or sole place of business from that referred to in Section 3.3; or

(ii) change its name, identity or corporate structure to such an extent that any financing statement filed by Lender in connection with this Agreement would become misleading.

Lender shall have the right, upon the occurrence and during the continuance of an Event of Default, in its discretion and without notice to Grantor, to transfer to or to register in its name or in the name of its nominees any or all of the Pledged Collateral. Lender shall have the right to, upon the occurrence and during the continuance of an Event of Default, exchange certificates or instruments representing or

evidencing any of the Pledged Collateral for certificates or instruments of smaller or larger denominations.

(b) Except as provided in Article V, Grantor shall be entitled to receive all cash dividends paid in respect of the Pledged Collateral (other than liquidating dividends constituting a distribution of capital) with respect to the Pledged Collateral. Any sums paid upon or in respect of any of the Pledged Collateral upon the liquidation or dissolution of any issuer of any of the Pledged Collateral, any distribution of capital made on or in respect of any of the Pledged Collateral or any property distributed upon or with respect to any of the Pledged Collateral pursuant to the recapitalization or reclassification of the capital of any issuer of Pledged Collateral or pursuant to the reorganization thereof shall, unless otherwise subject to a perfected security interest in favor of Lender, be delivered to Lender to be held by it hereunder as additional collateral security for the Secured Obligations or be deposited into an Approved Deposit Account.

ARTICLE V

REMEDIAL PROVISIONS

Section 5.1 Code and Other Remedies. During the continuance of an Event of Default, Lender may exercise, in addition to all other rights and remedies granted to it in this Agreement and in any other instrument or agreement securing, evidencing or relating to the Secured Obligations, all rights and remedies of a secured party under the UCC or any other applicable law. Without limiting the generality of the foregoing, Lender, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (in each case except any required by law referred to below) to or upon Grantor or any other Person (all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker's board or office of Lender or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. Lender shall have the right upon any such public sale or sales, and, to the extent permitted by law, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in Grantor, which right or equity is hereby waived and released. Lender shall apply the net proceeds of any action taken by it pursuant to this Section 5.1, after deducting all reasonable costs and expenses of every kind incurred in connection therewith or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of Lender hereunder, including reasonable attorneys' fees and disbursements, to the payment in whole or in part of the Secured Obligations, in such order as the Credit Agreement shall proscribe, and only after such application and after the payment by Lender of any other amount required by any provision of law, need Lender account for the surplus, if any, to Grantor. To the extent permitted by applicable law, Grantor waives all claims, damages and demands it may acquire against Lender arising out of the exercise by it of any rights hereunder. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least 10 days before such sale or other disposition.

Section 5.2 Pledged Collateral.

(a) During the continuance of an Event of Default, upon notice by Lender to Grantor, (i) Lender shall have the right to receive any and all cash dividends, payments or other Proceeds paid in respect of the Pledged Collateral and make application thereof to the Obligations in the order set forth in the Credit Agreement, and (ii) Lender or its nominee may exercise (A) all voting, consent, corporate and other rights pertaining to the Pledged Collateral at any meeting of shareholders, partners or members, as the case may be, of the relevant issuer or issuers of Pledged Collateral or otherwise and (B) any and all rights of conversion, exchange and subscription and any other rights, privileges or options pertaining to the Pledged Collateral as if it were the absolute owner thereof (including the right to exchange at its discretion any and all of the Pledged Collateral upon the merger, consolidation, reorganization, recapitalization or other fundamental change in the corporate structure of any issuer of Pledged Securities, the right to deposit and deliver any and all of the Pledged Collateral with any committee, depositary, transfer agent, registrar or other designated agency upon such terms and conditions as Lender may determine), all without liability except to account for property actually received by it, but Lender shall have no duty to Grantor to exercise any such right, privilege or option and shall not be responsible for any failure to do so or delay in so doing.

(b) In order to permit Lender to exercise the voting and other consensual rights which it may be entitled to exercise pursuant hereto and to receive all dividends and other distributions which it may be entitled to receive hereunder, (i) upon the occurrence and during the continuance of an

Event of Default, Grantor shall promptly execute and deliver (or cause to be executed and delivered) to Lender all such proxies, dividend payment orders and other instruments as Lender may from time to time reasonably request and (ii) without limiting the effect of clause (i) above, Grantor hereby grants to Lender an irrevocable proxy to vote all or any part of the Pledged Collateral and to exercise all other rights, powers, privileges and remedies to which a holder of the Pledged Collateral would be entitled (including giving or withholding written consents of shareholders, partners or members, as the case may be, calling special meetings of shareholders, partners or members, as the case may be, and voting at such meetings), which proxy shall be effective, automatically and without the necessity of any action (including any transfer of any Pledged Collateral on the record books of the issuer thereof) by any other person (including the issuer of such Pledged Collateral or any officer or agent thereof) during the continuance of an Event of Default and which proxy shall only terminate upon the payment in full of the Secured Obligations (in respect of Loans and Reimbursement Obligations and interest and fees thereon and expenses related thereto) and the termination of the Commitment.

(c) Grantor hereby expressly authorizes and instructs each issuer of any Pledged Collateral pledged hereunder by Grantor to (i) comply with any instruction received by it from Lender in writing that (A) states that an Event of Default has occurred and is continuing and (B) is otherwise in accordance with the terms of this Agreement, without any other or further instructions from Grantor, and Grantor agrees that 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 Collateral directly to an Approved Deposit Account approved for such purpose by Lender.

Section 5.3 Sale of Pledged Collateral.

(a) Grantor recognizes that Lender may be unable to effect a sale of any or all the Pledged Collateral by reason of certain prohibitions contained in the Securities Act and applicable state securities laws or otherwise or may determine that a public sale is impracticable or not commercially reasonable and, accordingly, may 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. Grantor 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. Lender shall be under no obligation to delay a sale of any of the Pledged Collateral 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) Grantor agrees to use its commercially reasonable efforts to do or cause to be done all such acts as may be necessary to make such sale or sales of all or any portion of the Pledged Collateral pursuant to this Section 5.3 valid and binding and in compliance with any and all applicable Requirements of Law, provided, however, that Grantor shall not be obligated to register any portion of the Pledged Collateral under the provisions of the Securities Act. Grantor further agrees that a breach of any of the covenants contained in this Section 5.3 will cause irreparable injury to Lender, that Lender has no adequate remedy at law in respect of such breach and, as a consequence, that each and every covenant contained in this Section 5.3 shall be specifically enforceable against Grantor, and Grantor 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 and is continuing.

Section 5.4 Deficiency. Grantor shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay the Secured Obligations and the fees and disbursements of any attorneys employed by Lender to collect such deficiency.

ARTICLE VI

POWER OF ATTORNEY

Section 6.1 Lender's Appointment as Attorney-in-Fact.

(a) Grantor hereby irrevocably constitutes and appoints Lender 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 of Grantor and in the name of Grantor or in its own name, for the purpose of carrying out the terms of this Agreement, to take any and all appropriate 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, Grantor hereby gives Lender the power and right, on behalf of Grantor, without notice to or assent by Grantor, to do any or all of the following:

(i) pay or discharge taxes and Liens levied or placed on the Collateral, effect any repairs or any insurance called for by the terms of this Agreement and pay all or any part of the premiums therefor and the costs thereof;

(ii) execute, in connection with any sale provided for in Section 5.1 or 5.3, any endorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral; and

(iii) (A) direct any party liable for any payment under any of the Collateral to make payment of any and all moneys due or to become due thereunder directly to Lender or as Lender shall direct; (B) ask or demand for, collect, and receive payment of and receipt for, any and all moneys, claims and other amounts due or to become due at any time in respect of or arising out of any Collateral; (C) commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to enforce any other right in respect of any Collateral; (D) defend any suit, action or proceeding brought against Grantor with respect to any Collateral; (E) settle, compromise or adjust any such suit, action or proceeding and, in connection therewith, give such discharges or releases as Lender may deem appropriate; and (F) generally, sell, transfer, pledge and make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though Lender were the absolute owner thereof for all purposes, and do, at Lender's option and Grantor's expense, at any time, or from time to time, all acts and things which Lender deems necessary to protect, preserve or realize upon the Collateral and Lender's security interests therein and to effect the intent of this Agreement, all as fully and effectively as Grantor might do.

Anything in this Section 6.1(a) to the contrary notwithstanding, Lender agrees that it will not exercise any rights under the power of attorney provided for in this Section 6.1(a) unless an Event of Default shall have occurred and be continuing.

(b) If Grantor fails to perform or comply with any of its agreements contained herein, and such failure constitutes an Event of Default, Lender (so long as such Event of Default is continuing), at its option, but without any obligation so to do, may perform or comply, or otherwise cause performance or compliance, with such agreement.

(c) The expenses of Lender incurred in connection with actions undertaken as provided in this Section 6.1, together with interest thereon at a rate per annum equal to the Applicable Rate at which interest would then be payable on past due Loans under the Credit Agreement, from the

date of payment by Lender to the date reimbursed by Grantor, shall be payable by Grantor to Lender on demand.

(d) Grantor hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof. All powers, authorizations and agencies contained in this Agreement are coupled with an interest and are irrevocable until this Agreement is terminated and the security interests created hereby are released.

Section 6.2 Duty of Lender. Lender's sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession shall be to deal with it in the same manner as Lender deals with similar property for its own account. Subject to applicable law, neither Lender nor any of its officers, directors, employees or agents shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of Grantor or any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. The powers conferred on Lender hereunder are solely to protect Lender's interest in the Collateral and shall not impose any duty upon Lender to exercise any such powers. Lender shall be accountable only for amounts that Lender actually receives as a result of the exercise of such powers, and neither Lender nor any of its officers, directors, employees or agents shall be responsible to Grantor for any act or failure to act hereunder.

Section 7.4 Successors and Assigns. This Agreement shall be binding upon the successors and assigns of Grantor and shall inure to the benefit of Lender and its successors and assigns; provided, however, that Grantor may not assign, transfer or delegate any of its rights or obligations under this Agreement without the prior written consent of Lender.

Section 7.6 Severability. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

At the request and sole expense of Grantor following any such termination, Lender shall deliver to Grantor any Collateral of Grantor held by Lender hereunder and execute and deliver to Grantor such documents as Grantor shall reasonably request to evidence such termination.
