SECTION 6.

RIGHTS OF THE LENDER.

(a) If an Event of Default shall occur and be continuing, all Proceeds received by the Pledgor shall be held by the Pledgor in trust for the Lender, segregated from other funds of the Pledgor, and shall, forthwith upon receipt by the Pledgor, be turned over to the Lender in the exact form received by the Pledgor (duly indorsed by the Pledgor to the Lender, if required). All money Proceeds received by the Lender hereunder shall be held in a Collateral Account. All Proceeds while held by the Lender in a Collateral Account (or by the Pledgor in trust for the Lender) shall continue to be held as collateral security for all the Obligations and shall not constitute payment thereof until applied as provided in paragraph (b).

(b) If an Event of Default shall occur and be continuing and the Lender shall give notice of its intent to exercise such rights to the Pledgor, (1) the Lender shall have the right to receive any and all cash dividends, payments or other Proceeds paid in respect of the Pledged Interests and make application thereof to the Obligations in such order as the Lender may determine, and (2) all of the Pledged Interests shall be registered in the name of the Lender or its nominee, and the Lender or its nominee may thereafter exercise (A) all voting and other rights pertaining to the Pledged interests at any meeting of members of the Borrower or otherwise and (B) any and all rights of conversion, exchange, subscription and any other rights, privileges or options pertaining to the Pledged Interests as if it were the absolute owner thereof (including, without limitation, the right to exchange at its discretion any and all of the Pledged Interests upon the merger, consolidation, reorganization, recapitalization or other fundamental change in the organizational structure of the Borrower, or upon the exercise by the Pledgor or the Lender of any right, privilege or option pertaining to such Pledged Interests, and in connection therewith, the right to deposit and deliver any and all of the Pledged Interests with any committee, depositary, transfer agent, registrar or other designated agency upon such terms and conditions as the Lender may determine), all without liability except to account for property actually received by it, but the Lender shall have no duty to the Pledgor to exercise any such right, privilege or option and shall not be responsible for any failure to do so or delay in so doing.

SECTION 7

REMEDIES.

(a) Application of Proceeds. If an Event of Default shall have occurred and be continuing, at any time at the Lender's election, the Lender may apply all or any part of Proceeds constituting Collateral, whether or not held in any Collateral Account, in payment of the Obligations in such order as the Lender may elect.

(b) Code and Other Remedies. If an Event of Default shall have occurred and be continuing, the Lender, may exercise, in addition to all other rights and remedies granted in this Agreement and in any other instrument or agreement securing, evidencing or relating to the Obligations, all rights and remedies of a secured party under the Code or any other applicable law. Without limiting the generality of the foregoing, the Lender, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below) to or upon the Pledgor 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, 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, in the over-the-counter market, at any exchange, broker's board or office of the 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. The Lender shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in the Pledgor, which right or equity is hereby waived or released. The Lender shall apply any Proceeds from time to time held by it and the net proceeds of any such collection, recovery, receipt, appropriation, realization or sale, after deducting all costs and expenses of every kind incurred in respect thereof or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the Lender hereunder, including, without limitation, attorney's fees and disbursements, to the payment in whole or in part of the Obligations, in such order as the Lender may elect, and only after such application and after the payment by the Lender of any other amount required by any provision of law, need the Lender account for the surplus, if any, to the Pledgor. To the extent permitted by applicable law, the Pledgor waives all claims, damages and demands it may acquire against the Lender arising out of the exercise by them 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 ten (10) days before such sale or other disposition.

SECTION 8.	[Intentionally omitted]

SECTION 9.	PRIVATE SALES.

(a) The Pledgor recognizes that the Lender may be unable to effect a public sale of any or all the Pledged Interests, by reason of certain prohibitions under applicable federal and state law or otherwise, and may be compelled to 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. The Pledgor 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. The Lender shall be under no obligation to delay a sale of any of the Pledged Interests for the period of time necessary to permit the Borrower to register such securities for public sale under the Securities Act, or under applicable state securities laws, even if the Borrower would agree to do so.

(b) The Pledgor further agrees to use its best efforts to do or cause to be done all such other acts as may be necessary to make such sale or sales of all or any portion of the Pledged Interests pursuant to this Section valid and binding and in compliance with any and all other applicable requirements of federal or state law. The Pledgor further agrees that a breach of any of the covenants contained in this Section 9 will cause irreparable injury to the Lender, that the 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 9 shall be specifically enforceable against the Pledgor, and the Pledgor hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants.

SECTION 10. SUBORDINATION. The Pledgor hereby agrees that, upon the occurrence and during the continuance of an Event of Default, unless otherwise agreed by the Lender, all Indebtedness owing by it shall be fully subordinated to the indefeasible payment in full in cash of the Obligations.

SECTION 11. IRREVOCABLE AUTHORIZATION AND INSTRUCTION TO BORROWER. The Pledgor hereby authorizes and instructs the Borrower to comply with any instruction

- 7 -

received by it from the Lender in writing that (a) states that an Event of Default has occurred and (b) is otherwise in accordance with the terms of this Agreement, without any other or further instructions from the Pledgor.

SECTION 12.	LENDER'S APPOINTMENT AS ATTORNEY-IN-FACT.

	12.1	Lender's Appointment as Attorney-in-Fact, etc.

(a) The Pledgor hereby irrevocably constitutes and appoints the Lender and any officer or agent of the Lender, with full power of substitution, as its true and lawful attorneyin-fact with full irrevocable power and authority in the place and stead of the Pledgor and in the name of the Pledgor or in its own name, from time to time in the Lender's discretion, 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.

(b) If the Pledgor fails to perform or comply with any of its agreements contained herein, the Lender, at its option, but without any obligation so to do, may perform or comply, or otherwise cause performance or compliance, with such agreement (and shall give the Pledgor notice thereof).

(c) The Pledgor 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 13. DUTY OF LENDER. The 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 the Lender deals with similar securities and property for its own account. Neither the Lender nor any of its directors, officers, 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 the Pledgor or any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. The powers conferred on the Lender hereunder are solely to protect the Lender's interests in the Collateral and shall not impose any duty upon the Lender to exercise any such powers. The Lender shall be accountable only for amounts that it actually receives as a result of the exercise of such powers, and neither it nor any of its officers, directors, employees or agents shall be responsible to the Pledgor for any act or failure to act hereunder.

SECTION 14. EXECUTION OF FINANCING STATEMENTS. The Pledgor hereby irrevocably authorizes the Lender to file or record at any time and from time to time in any jurisdiction in which the Code has been adopted initial financing statements or amendments thereof and other filing or recording documents or instruments with respect to the Collateral without the signature of the Pledgor in such form and in such filing offices as the Lender determines appropriate. The Xxxxxxx hereby ratifies and authorizes the filing by the Lender of any financing statement with respect to the Collateral made prior to the date hereof. A carbon, photographic or other reproduction of this Agreement shall be sufficient as a financing statement for filing in any jurisdiction.

SECTION 15. NOTICES. All notices, requests and demands to or upon the Lender or the Pledgor to be effective shall be in writing (or by telex, fax or similar electronic transfer confirmed

in writing) and shall be deemed to have been duly given or made (1) when delivered by hand or (2) if given by mail, three (3) days after being deposited in the mails by certified mail, return receipt requested, or (3) if by telex, fax or similar electronic transfer, when sent and receipt has been confirmed, addressed to the Lender or the Pledgor at its address or transmission number for notices as set forth below.
