Each such certificate shall be registered in the name of Pledgor, duly endorsed in blank or accompanied by a stock power duly executed by Pledgor in blank, in form and substance satisfactory to Secured Party, with any and all documentary tax stamps and other documents necessary to cause Secured Party to have a good, valid and perfected continuing first priority pledge of, Lien on and security interest in the Pledged Collateral, free and clear of any mortgage, pledge, Lien, security interest, hypothecation, assignment, charge, right, encumbrance or transfer or other restriction (individually, “Encumbrance” and collectively, “Encumbrances”), including, without limitation, any necessary notations in the corporate or other records books of Pledgor or the entity in which such shares, equity securities or ownership interests evidence an ownership stake.

(d)       In addition to and notwithstanding any other provision of this Agreement, Secured Party, in its sole discretion, shall have the right, at any time that Pledgor fails to do so, without prior notice to Pledgor, to: (i) obtain insurance covering any of the Pledged Collateral to the extent required under the Loan Agreement, if any, (ii) pay for the performance of any of the Pledgor’s obligations hereunder; (iii) discharge taxes, liens, security interests, or other encumbrances at any time levied or placed on any of the Pledged Collateral in violation of this Agreement unless Pledgor is in good faith with due diligence by appropriate proceedings contesting those items; and (iv) pay for the maintenance and preservation of any of the Pledged Collateral to the extent reasonably necessary. Such expenses and advances shall be added to the Secured Obligations until reimbursed to Secured Party and shall be secured by the Pledged Collateral.

(f)        No injury to, or loss or destruction of, the Pledged Collateral or any Material Adverse Effect or Material Adverse Change shall relieve Pledgor of any of the Secured Obligations.

3.        VOTING RIGHTS, DIVIDENDS AND DISTRIBUTIONS

So long as no Event of Default shall have occurred and be continuing or would result from or be caused by any of the following:

(a)       Pledgor shall be entitled to exercise any and all voting and/or consensual rights and powers relating or pertaining to the Pledged Collateral or any part thereof, subject to the terms hereof;

(b)       [Omitted]

(c)       Secured Party shall execute and deliver (or cause to be executed and delivered) to Pledgor all such proxies, powers of attorney, dividend orders and other instruments as Pledgor may

3

request for the purpose of enabling Pledgor to exercise the voting and/or consensual rights and powers that Pledgor is entitled to exercise pursuant to Section 3(a); and

(d)       Upon the occurrence and continuation of an Event of Default, all rights of Pledgor to exercise the voting and/or consensual rights and powers that Pledgor is entitled to exercise pursuant to Section 3(a) shall cease immediately without any notice to Pledgor or action by or on behalf of Secured Party or any other Person, and all such rights thereupon shall become vested in Secured Party automatically without any action by any Person, and Secured Party shall have the sole and exclusive right and authority to exercise such voting and/or consensual rights and powers and/or to receive and retain such dividends. In such case, Pledgor shall execute and deliver such proxies, powers of attorney, dividend orders and other instruments and documents as Secured Party may request or as may be otherwise required or desirable to enable Secured Party to exercise such rights and receive such dividends. In addition, Secured Party is hereby appointed the attorney-in-fact of Pledgor, with full power of substitution, which appointment as attorney-in-fact is irrevocable and coupled with an interest, to take all such actions after the occurrence and continuation of an Event of Default, whether in the name of Secured Party or Pledgor, as Secured Party may consider necessary or desirable for the purpose of exercising such rights and receiving such dividends. Any and all money and other property paid over to or received by Secured Party pursuant to the provisions of this Section 3(d) shall be retained by Secured Party as part of the Pledged Collateral and shall be applied in accordance with the provisions hereof.

4.        REMEDIES ON DEFAULT

(a)       Notwithstanding and without limiting any other provision of this Agreement or any of the Loan Documents, if at any time an Event of Default shall have occurred and be continuing, then, in addition to having the right to exercise any right or remedy of a secured party upon default under the UCC or applicable law or at equity, Secured Party may, to the extent permitted by law, without being required to give any notice to Pledgor or to take or do any action (except as provided below):

(i)        apply any cash held by it hereunder in the manner provided in Section 4(l); and

(ii)       if there shall be no such cash or if the cash so applied shall be insufficient to pay in full the items specified in Section 4(l)(i) and 4(l)(ii), collect, receive, appropriate and realize upon the Pledged Collateral or any part thereof, and/or sell, assign, transfer, contract to sell or otherwise dispose of and deliver the Pledged Collateral or any part thereof, in its entirety or in portions, at public or private sale or at any broker’s board, on any securities exchange or at any of Secured Party’s places of business or elsewhere, for cash, upon credit or for future delivery, and at such price or prices as Secured Party may deem best, and Secured Party may (except as otherwise provided by law) be the purchaser of any or all of the Pledged Collateral so sold and thereafter may hold the same, absolutely, free from any right or claim of whatsoever kind.

(b)       In the event of a sale as aforesaid, Secured Party may, at any such sale, restrict the number of prospective bidders or purchasers and/or further restrict such prospective bidders or 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 the Pledged Collateral, and may otherwise require that such sale be conducted subject to restrictions as to such other matters as Secured Party may deem necessary in order that such sale may be effected in such manner as to comply with all applicable state and federal securities and other laws. Upon any such sale, Secured Party shall have the right to deliver, assign and transfer the Pledged Collateral so sold to the purchaser thereof.

(c)       Pledgor hereby acknowledges that, notwithstanding that a higher price might be obtained for the Pledged Collateral at a public sale than at a private sale or sales, the making of a public sale of the Pledged Collateral may be subject to registration requirements under applicable securities laws and other legal restrictions, compliance with which would make a public sale of the Pledged Collateral impractical. Accordingly, Pledgor hereby agrees that private sales made by Secured Party in

4

good faith in accordance with the provisions of this Article 4 may be at prices and on other terms less favorable to the seller than if the Pledged Collateral were sold at a public sale, and that Secured Party shall not have any obligation to take any steps in order to permit the Pledged Collateral to be sold at a public sale.

(d)       Intentionally omitted.

(e)       Each purchaser at any such sale shall hold the property sold, absolutely free from any claim or right whatsoever, including any equity or right of redemption of Pledgor, and Pledgor hereby specifically waives all rights of redemption, stay or appraisal and other rights that Pledgor has or may have under any law, regulation or statute now existing or hereafter adopted or otherwise. Secured Party shall give Pledgor not less than ten (10) calendar days’ written notice of its intention to make any such public or private sale. Such notice, in case of a public sale, shall state the time and place fixed for such sale, and, in case of a sale at broker’s board, on a securities exchange, at one or more of Secured Party’s places of business or elsewhere, shall state the board, exchange or other location at which such sale is to be made and the day on which the Pledged Collateral, or that portion thereof so being sold, will first be offered for sale at such location. Such notice, in case of a private sale, shall state only the date on or after which such sale may be made. Any such notice given as aforesaid shall be deemed to be reasonable notification.

(f)        Any such public sale shall be held at such time or times within ordinary business hours and at such place or places as Secured Party may fix in the notice of such sale. At any sale the Pledged Collateral may be sold in one lot as an entirety or in parts, as Secured Party may determine. Secured Party shall not be obligated to make any sale pursuant to any such notice. Secured Party may, without notice or publication, adjourn any sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for the sale, and such sale may be made at any time or place to which the same may be so adjourned. In case of any sale of all or any part of the Pledged Collateral on credit or for future delivery, the Pledged Collateral so sold may be retained by Secured Party until the selling price is paid by the purchaser thereof, but Secured Party shall not incur any liability in case of the failure of such purchaser to take up and pay for the Pledged Collateral so sold and, in case of any such failure, such Pledged Collateral may again be sold upon like notice.

(g)       Secured Party, instead of exercising the power of sale herein conferred upon it, may proceed by a suit or suits at law or in equity to foreclose its Lien or security interest arising from this Agreement and sell the Pledged Collateral, or any portion thereof, under a judgment or decree of a court or courts of competent jurisdiction.

(h)       Notwithstanding and without limiting any other provision of this Agreement or any of the Loan Documents, upon the occurrence and continuation of an Event of Default, Secured Party or its nominee shall have the right, without notice to or the consent of Pledgor, to exercise any and all rights of conversion, exchange or subscription and any other rights, privileges or options pertaining to any of the Pledged Collateral as if it were the absolute owner thereof, including, without limitation, the right to transfer, sell, dispose of or exchange, at its discretion, any or all of the Pledged Collateral upon the merger, consolidation, reorganization, recapitalization or other readjustment of Pledgor or subsidiary of Pledgor or such other Person.

(i)        On any sale of any part of the Pledged Collateral, Secured Party is hereby authorized to comply with any limitation or restriction in connection with such sale that may be necessary in order to avoid any violation of applicable law or in order to obtain any required approval of the purchaser(s) by any Governmental Authority or officer or court.

(j)        Pledgor hereby acknowledges, understands and agrees that Secured Party (i) may exercise its rights under the Loan Documents, whether or not they provide security for any of the Secured Obligations, without exercising its rights hereunder or affecting the security provided hereunder, and (ii) may proceed against all or any portion of the Pledged Collateral and all other collateral securing

5

any of the Secured Obligations in such order and at such time as determined by Secured Party in its sole discretion. Pledgor hereby expressly waives any rights under the doctrine of marshalling of assets.

(k)       Pledgor hereby acknowledges, understands and agrees that compliance with the foregoing procedures shall satisfy any applicable requirements that such sale or disposition be made in a commercially reasonable manner.

(l)        The proceeds of any collection, recovery, receipt, appropriation, realization, transfer, exchange, disposition or sale as aforesaid shall be applied by Secured Party in the following order:

(i)        First, to the payment of all costs and expenses of every kind incurred by Secured Party in connection therewith or incidental to the care, safekeeping or otherwise of any of the Pledged Collateral, and to the payment of all sums which Secured Party may be required or may elect to pay, if any, for taxes, assessments, insurance and other charges upon the Pledged Collateral or any part thereof, and all other payments that Secured Party may be required or authorized to make under any provision of this Agreement including, without limitation, in-house documentation and diligence fees, search, audit, recording, and filing fees and expenses and reasonable attorneys’ fees and expenses;

(ii)       Second, to the payment of any other amounts due under the Secured Obligations (to be applied in accordance with the Loan Agreement);

(iii)      Third, to the satisfaction of indebtedness secured by any subordinate security interest of record in the Pledged Collateral if written notification of demand therefor is received before distribution of the proceeds is completed; provided that the holder of a subordinate security interest shall furnish reasonable proof of its interest to Secured Party, and unless it does so, Secured Party need not address its claims; and

(iv)      Finally, to the payment to Pledgor of any surplus then remaining from such proceeds, unless otherwise required by law or directed by a court of competent jurisdiction; provided that Pledgor shall be liable for any deficiency if such proceeds are insufficient to satisfy all of the Secured Obligations.

If any Indemnified Person uses in-house counsel for any purpose for which Pledgor is responsible to pay or indemnify, Pledgor expressly agrees that its indemnification obligations include reasonable charges for such work commensurate with the fees that would otherwise be charged by outside legal counsel selected by such Indemnified Person in its sole discretion for the work performed. Secured Party agrees to give Pledgor reasonable notice of any event of which Secured Party becomes aware for which indemnification may be required under this Section 7.9, and Secured Party may elect (but is not obligated) to direct the defense thereof, provided that the selection of counsel shall be subject to Pledgor’s consent, which consent shall not be unreasonably withheld or delayed. Any Indemnified Person may, in its reasonable discretion, take such actions as it deems necessary and appropriate to

investigate, defend or settle any event or take other remedial or corrective actions with respect thereto as may be necessary for the protection of such Indemnified Person or the Pledged Collateral. Notwithstanding the foregoing, if any insurer agrees to undertake the defense of an event (an “Insured Event”), Secured Party agrees not to exercise its right to select counsel to defend the event if that would cause Pledgor’s insurer to deny coverage; provided, however, that Secured Party reserves the right to retain counsel to represent any Indemnified Person with respect to an Insured Event at its sole cost and expense. To the extent that Secured Party obtains recovery from a third party other than an Indemnified Person of any of the amounts that Pledgor has paid to Secured Party pursuant to the indemnity set forth in this Section 7.9, then Secured Party shall promptly pay to Pledgor the amount of such recovery.

7.10.   Waiver of Notice; Waiver of Statute of Limitations; Defenses

Pledgor hereby waives demand, presentment, protest, notice of dishonor or non-payment, as well as all defenses with respect to any and all instruments, notice of acceptance hereof, notice of Loans or Advances made, credit extended, collateral received or delivered, or any other action taken by Secured Party in reliance hereon, and all other demands and notices of any description, except such as are expressly provided for herein. The pleading of any statute of limitations as a defense to any demand against Pledgor hereunder and under the Loan Documents is expressly waived by Pledgor. Pledgor hereby waives any and all defenses and counterclaims it may have or could interpose in any action or procedure brought by Secured Party to obtain an order of court recognizing the assignment of or security interests and Liens of Secured Party in and to the Pledged Collateral.

7.11.   Jury Waiver

TO THE FULLEST EXTENT PERMITTED BY LAW, EACH PARTY TO THIS AGREEMENT HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION ARISING UNDER THIS AGREEMENT OR IN ANY WAY CONNECTED WITH OR INCIDENTAL TO THE DEALING OF THE PARTIES WITH RESPECT TO ANY OF THE LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED THEREBY, WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE. EACH PARTY HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENTS OF THE PARTIES TO THE WAIVER OF THEIR RESPECTIVE RIGHTS TO TRIAL BY JURY.

7.12.   Entire Agreement

This Agreement and the other Loan Documents to which Pledgor is a party constitute the entire agreement between Pledgor and Secured Party with respect to the subject matter hereof and thereof, and supersede all prior agreements and understandings, if any, relating to the subject matter hereof or thereof. Any promises, representations, warranties or guarantees not herein contained and hereinafter made shall have no force and effect unless in writing signed by Pledgor and Secured Party. No provision of this Agreement may be changed, modified, amended, restated, waived, supplemented, discharged, canceled or terminated orally or by any course of dealing or in any other manner other than by an agreement in writing signed by Secured Party and Pledgor. Each party hereto acknowledges that it has been advised by counsel in connection with the negotiation and execution of this Agreement and is not relying upon oral representations or statements inconsistent with the terms and provisions hereof.

7.13.   No Duty of Secured Party

Secured Party shall have no responsibility for or obligation or duty with respect to all or any part of the Pledged Collateral or any matter or proceeding arising out of or relating thereto, including

14

7.15    Release of Secured Party

Pledgor acknowledges that the foregoing release is a material inducement to Secured Party’s decision to extend to Pledgor the financial accommodations under the Loan Documents and has been relied upon by Secured Party in agreeing to make the Loans and in making each Advance thereunder.
