4.2 Defense of Title. Pledgor agrees, at its sole cost and expense, to defend Lender’s right, title, lien and security interest in and to the Collateral against the claims, rights, equities, liens and demands of all persons.

4.3 Other Liens. Except for the lien and security interest granted by this Agreement, the Collateral is now, and at all times will be, maintained by Pledgor free and clear of all liens, security interests, charges, pledges or encumbrances.

4.4 Taxes; Assessments.

4.5 Further Assurances. Pledgor will, at its sole cost and expense, perform all acts and execute all documents reasonably requested of Pledgor by Lender from time to time to evidence, perfect, maintain or enforce Lender’s lien and security interest in the Collateral granted hereby, or otherwise in furtherance of the provisions of this Agreement, and the transactions contemplated hereby, including, without limitation, any act which may be required to effect a sale or other disposition of the Collateral.

4.7 Financing Statement (UCC-1).

-3-

6. Voting Rights, Dividends, Etc. Subject to Section 7 hereof, and prior to the occurrence of a Default, Pledgor shall be entitled to: (a) vote the Pledged Shares; (b) give consents, waivers and ratifications with respect thereto; and (c) otherwise act with respect to the Pledged Shares as though Pledgor were the outright owner thereof. Upon the occurrence of a Default, all rights of Pledgor under this Section 6 shall immediately cease and all such rights shall immediately become vested in Lender.

7. Remedies Upon Default. After a Default shall have occurred, Lender may, without notice to or demand upon Pledgor, take the actions set forth below.

7.1 Remedies Provided by Applicable law. Lender may, exercise any remedies available to a secured party under applicable law.

7.2 Foreclosure Sale. Lender may, without notice or publication, adjourn any public or private sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for sale, and such sale, without further notice, may be made at the time and place to which the same was so adjourned.

(a) At any sale made pursuant to this Agreement, Lender may bid for or purchase, free from any rights of redemption, stay or appraisal on the part of Pledgor (all said rights being hereby unconditionally and irrevocably waived and released by Pledgor to the extent permitted by law), any part or all of the Collateral offered for sale and may make payment on account thereof by using any of the Obligations as a credit against the purchase price, and Lender may, upon compliance with the terms of the sale, hold, retain and dispose of such property without further accountability to Pledgor.

(b) As an alternative to exercising the power of sale herein conferred upon it, Lender may proceed by a suit or suits at law or in equity to foreclose against any of the Collateral pledged pursuant to this Agreement and to sell the Collateral, or any portion thereof, pursuant to a judgment or decree of a court or courts of competent jurisdiction. In the event of any sale or alternative thereto hereunder, Lender shall, after deducting all costs and expenses of every kind for care, safekeeping, collection, sale, deliver, legal proceedings (including, without limitation, the fees and disbursements of legal counsel) or otherwise apply the residue of the proceeds of the sale, together with any other moneys at the time held by it hereunder, as set forth in Section 12 hereof.

8. Securities Laws. In the event that a question arises under the Securities Act of 1933, as now or hereafter in effect, or any similar Federal statute hereafter in effect, or any similar statute hereafter enacted analogous in purpose or effect (such Act and any such similar statute as from time to time in effect hereinafter called the “Federal Securities Laws”), with respect to any disposition of the Pledged Shares, Pledgor understands that compliance with the Federal Securities Laws may severely restrict and limit Lender’s conduct in attempting to dispose of all or any part of the Pledged Shares and may also limit the extent to which and the manner in which any subsequent transferee of any of the Pledged Shares may dispose of the same.

-4-

9. Lender Appointed Attorney-in-Fact. Pledgor hereby irrevocably appoints Lender as its attorney-in-fact for the purpose of carrying out the provisions of this Agreement and taking any action and executing any instrument which Lender may, in its sole and absolute discretion, deem necessary or advisable to accomplish the purposes hereof, which appointment is irrevocable and coupled with an interest, but such attorney-in-fact shall not be effective until a Default shall have occurred. Without limiting the generality of the foregoing, Lender shall have the right and power, if a Default shall have occurred to: (a) ask for, demand, collect, sue for, receive, endorse and collect all checks and other orders for the payment of money made payable to Pledgor representing any interest or dividend or other distribution payable in respect of the Pledged Shares or any part thereof and to give full discharge for the same; (b) give any necessary receipts for amounts collected or received by Lender pursuant to this Agreement and make all necessary transfers of all or any part of the Collateral in connection with any sale or other disposition thereof made pursuant to this Agreement, and for that purpose to execute all necessary instruments of assignment and transfer; (c) commence and prosecute any and all suits, actions or proceedings in law or in equity in any court of competent jurisdiction to collect or otherwise realize on all or any part of the Collateral or to enforce any rights in respect thereof; and (d) settle, compromise, compound, adjust or defend any actions, suits or proceedings relating to any or all of the Collateral.

10. Waiver of Rights by Pledgor; Delay by Lender Not a Waiver.

10.1 Waiver. To the full extent that it may lawfully so agree, Pledgor will not at any time plead, claim or take the benefit of any appraisal, valuation, stay, extension, moratorium or redemption law, as now or hereafter in force or effect, in order to prevent or delay the enforcement of this Agreement or the sale of all or any portion of the Collateral, or the possession thereof by any purchaser at any sale; and Pledgor, for itself, and all parties claiming by, through and under it, to the extent permitted by law, hereby unconditionally and irrevocably waives the benefit of all such laws. Pledgor, for itself and all parties claiming, by, through or under it, to the extent permitted by law, also unconditionally and irrevocably waives all right to have all or any portion of the Collateral marshalled upon any foreclosure thereof and agrees that any court having jurisdiction over this Agreement may order the sale of all or any portion of the Collateral. Any sale of all or any part of the Collateral in accordance with this Agreement shall operate to divest all right, title, interest, claim and demand, either at law or in equity, of Pledgor in and to the Collateral so sold, optioned or realized upon, and shall be a perpetual bar both at law and in equity against Pledgor and against any and all persons claiming or attempting to claim the Collateral so sold, optioned or realized upon, or any part thereof, from, through and under Pledgor. Pledgor hereby unconditionally and irrevocably waives presentment, notice of dishonor and protest of any instruments included in or evidencing any of the Obligations or the Collateral.

10.2 Delay Not a Waiver. To the extent permitted by law, no delay on Lender’s part in exercising any power of sale, lien, option or other right hereunder, and no notice or demand which may be given to or made upon Pledgor with respect to any power of sale, lien, option or other right hereunder, shall constitute a waiver thereof, or limit or impair the right of Lender to take any action or to exercise any power of sale, lien, option or any other right under this Agreement, or otherwise, nor shall any single or partial exercise of any such power of sale, lien, option or other right preclude any other or further exercise thereof, or the exercise of any power, lien, option or other right under this Agreement or otherwise, all without notice or demand (except such notice as is otherwise required by this Agreement), nor shall any of the same prejudice the rights of Lender as against Pledgor in any respect. Any waiver must be in writing and be signed by the party or parties against whom the waiver is sought.

-5-

11. Remedies Unlimited. Lender shall have the right to sell all or any part of the Collateral at such time and in such order as it may elect, in its sole and absolute discretion, or to enforce any one or more remedies, individually or cumulatively, relative hereto either successively or concurrently, and Pledgor hereby agrees that the liens, options and other rights hereby given to Lender shall remain unimpaired and unprejudiced and that the enforcement of any remedy shall not operate to bar or estop Lender from exercising any other right or remedy. Each and every remedy of Lender shall be in addition to any other remedy given hereunder or now or hereafter existing at law or in equity or by statute or otherwise.

12. Application of Proceeds of Sale and Other Property. The proceeds of any sale of Collateral sold pursuant to this Agreement shall be applied by Lender as follows:

FIRST: to the payment of all costs and expenses incurred by Lender in connection with such sale, including, but not limited to, the reasonable fees and expenses of legal counsel for Lender incurred in connection therewith, and to the payment of all advances made by Lender hereunder for the account of Pledgor and the payment of all costs and expenses paid or incurred by Lender upon the exercise of any right or remedy hereunder, under the Note or this Agreement; and

SECOND: to the payment in full or reduction of the Obligations (to the extent not previously paid).

Amounts remaining after payment in full of the Obligations shall be remitted to Pledgor.

13. Indemnification. Pledgor agrees to indemnify, defend and hold harmless Lender (to the full extent permitted by law) from and against any and all claims, demands, losses, judgments and liabilities (including, without limitation, liabilities for penalties) of whatever nature with respect to this Agreement the Note, the Obligations or the Collateral, and to reimburse Lender for all out-of-pocket costs and expenses, including, without limitation, legal fees and disbursements with respect thereto.

14. Pledgor Not Discharged.

The lien and security interests created by this Agreement shall terminate on the date when both: (a) the Note and the obligations under this Agreement have been paid and/or performed in full; and (b) all Obligations secured hereby shall have been fully paid, together with any interest thereon, at which time Lender shall reassign and redeliver (or cause to be so reassigned and redelivered), without recourse upon or warranty by Lender, and at the sole expense of Pledgor, to Pledgor, against receipt therefor, such of the Collateral, if any, as shall not have been sold or otherwise applied by Lender pursuant to the terms hereof and not theretofore reassigned and redelivered to Pledgor, together with appropriate instruments of reassignment and release.
