(a) Without the prior written consent of Lender, Pledgor will not sell, assign, transfer, pledge, or otherwise encumber any of its rights in or to the Pledged Collateral, or any unpaid dividends, interest or other distributions or payments with respect to the Pledged Collateral or ▇▇▇▇▇ ▇ ▇▇▇▇ in the Pledged Collateral, unless otherwise expressly permitted by the Loan Agreement;

(b) Pledgor will, at its expense, promptly execute, acknowledge and deliver all such instruments and take all such actions as Lender from time to time may request in order to ensure to Lender the benefits of the Liens in and to the Pledged Collateral intended to be created by this Agreement, including the filing of any necessary Code financing statements, which may be filed by Lender with or (to the extent permitted by law) without the signature of Pledgor, and will cooperate with Lender, at Pledgor’s expense, in obtaining all necessary approvals and making all necessary filings under federal, state, local or foreign law in connection with such Liens or any sale or transfer of the Pledged Collateral;

(c) Pledgor has and will defend the title to the Pledged Collateral and the Liens of Lender in the Pledged Collateral against the claim of any Person and will maintain and preserve such Liens; and

(d) Pledgor will, upon obtaining ownership of any additional Stock or promissory notes or instruments of a Pledged Entity or Stock or promissory notes or instruments otherwise required to be pledged to Lender pursuant to any of the Loan Documents, which Stock, notes or instruments are not already Pledged Collateral, promptly (and in any event within three (3) Business Days) deliver to Lender a Pledge Amendment, duly executed by Pledgor, in substantially the form of Schedule II hereto (a “Pledge Amendment”) in respect of any such additional Stock, notes or instruments, pursuant to which Pledgor shall pledge to Lender all of such additional Stock, notes and instruments. Pledgor hereby authorizes Lender to attach each Pledge Amendment to this Agreement and agrees that all Pledged Shares listed on any Pledge Amendment delivered to Lender shall for all purposes hereunder be considered Pledged Collateral.

7. Pledgor’s Rights. As long as no Event of Default shall have occurred and be continuing and until written notice shall be given to Pledgor in accordance with Section 8(a) hereof:

(a) Pledgor shall have the right, from time to time, to vote and give consents with respect to the Pledged Collateral, or any part thereof for all purposes not inconsistent with the provisions of this Agreement, the Loan Agreement or any other Loan Document; provided, however, that no vote shall be cast, and no consent shall be given or action taken, which would have the effect of impairing the position or interest of Lender in respect of the Pledged Collateral or which would authorize,

effect or consent to (unless and to the extent expressly permitted by the Loan Agreement):

(i) the dissolution or liquidation, in whole or in part, of a Pledged Entity;

(ii) the consolidation or merger of a Pledged Entity with any other Person;

(iii) the sale, disposition or encumbrance of all or substantially all of the assets of a Pledged Entity, except for Liens in favor of Lender;

(iv) any change in the authorized number of shares, the stated capital or the authorized share capital of a Pledged Entity or the issuance of any additional shares of its Stock; or

(v) the alteration of the voting rights with respect to the Stock of a Pledged Entity; and

(b) except as expressly permitted under the Loan Agreement, all dividends, payments and interest and all other distributions in respect of any of the Pledged Shares, whenever paid or made, shall be delivered to Lender to hold as Pledged Collateral and shall, if received by Pledgor, be received in trust for the benefit of Lender, be segregated from the other property or funds of Pledgor, and be forthwith delivered to Lender as Pledged Collateral in the same form as so received (with any necessary endorsement).

8. Defaults and Remedies; Proxy.

(a) Upon the occurrence of an Event of Default and during the continuation of such Event of Default, and concurrently with written notice to Pledgor, Lender (personally or through an agent) is hereby authorized and empowered to transfer and register in its name or in the name of its nominee the whole or any part of the Pledged Collateral, to exchange certificates or instruments representing or evidencing Pledged Collateral for certificates or instruments of smaller or larger denominations, to exercise the voting and all other rights as a holder with respect thereto, to collect and receive all cash dividends, interest, principal and other distributions made thereon, to sell in one or more sales after ten (10) days’ notice of the time and place of any public sale or of the time at which a private sale is to take place (which notice Pledgor agrees is commercially reasonable) the whole or any part of the Pledged Collateral and to otherwise act with respect to the Pledged Collateral as though Lender was the outright owner thereof. Any sale shall be made at a public or private sale at Lender’s place of business, or at any place to be named in the notice of sale, either for cash or upon credit or for future delivery at such price as Lender may deem fair, and Lender may be the purchaser of the whole or any part of the Pledged Collateral so sold and hold the same thereafter in its own right free from any claim of Pledgor or any right of redemption. Each sale shall be made to the highest bidder, but Lender reserves the right to reject any and all bids at such sale which, in its discretion, it shall deem inadequate. Demands of performance, except as otherwise herein specifically provided for, notices of sale, advertisements and the presence of property at sale are hereby waived and any sale hereunder may be conducted by an auctioneer or any officer or agent of Lender. PLEDGOR HEREBY IRREVOCABLY CONSTITUTES AND APPOINTS LENDER AS THE PROXY AND ATTORNEY IN FACT OF PLEDGOR WITH RESPECT TO THE PLEDGED COLLATERAL, INCLUDING THE RIGHT TO VOTE THE PLEDGED SHARES, WITH FULL POWER OF

SUBSTITUTION TO DO SO. THE APPOINTMENT OF LENDER AS PROXY AND ATTORNEY IN FACT IS COUPLED WITH AN INTEREST AND SHALL BE IRREVOCABLE UNTIL THE TERMINATION DATE. IN ADDITION TO THE RIGHT TO VOTE THE PLEDGED SHARES, THE APPOINTMENT OF LENDER AS PROXY AND ATTORNEY IN FACT SHALL INCLUDE THE RIGHT TO EXERCISE ALL OTHER RIGHTS, POWERS, PRIVILEGES AND REMEDIES TO WHICH A HOLDER OF THE PLEDGED SHARES WOULD BE ENTITLED (INCLUDING GIVING OR WITHHOLDING WRITTEN CONSENTS OF SHAREHOLDERS, CALLING SPECIAL MEETINGS OF SHAREHOLDERS AND VOTING AT SUCH MEETINGS). SUCH PROXY SHALL BE EFFECTIVE, AUTOMATICALLY AND WITHOUT THE NECESSITY OF ANY ACTION (INCLUDING ANY TRANSFER OF ANY PLEDGED SHARES ON THE RECORD BOOKS OF THE ISSUER THEREOF) BY ANY PERSON (INCLUDING THE ISSUER OF THE PLEDGED SHARES OR ANY OFFICER OR AGENT THEREOF), UPON THE OCCURRENCE OF AN EVENT OF DEFAULT. NOTWITHSTANDING THE FOREGOING, LENDER SHALL NOT HAVE ANY DUTY TO EXERCISE ANY SUCH RIGHT OR TO PRESERVE THE SAME AND SHALL NOT BE LIABLE FOR ANY FAILURE TO DO SO OR FOR ANY DELAY IN DOING SO.

(b) If, at the original time or times appointed for the sale of the whole or any part of the Pledged Collateral, the highest bid, if there be but one sale, shall be inadequate to discharge in full all the Obligations, or if the Pledged Collateral be offered for sale in lots, if at any of such sales, the highest bid for the lot offered for sale would indicate to Lender, in its discretion, that the proceeds of the sales of the whole of the Pledged Collateral would be unlikely to be sufficient to discharge all the Obligations, Lender may, on one or more occasions and in its discretion, postpone any of said sales by public announcement at the time of sale or the time of previous postponement of sale, and no other notice of such postponement or postponements of sale need be given, any other notice being hereby waived; provided, however, that any sale or sales made after such postponement shall be after ten (10) days’ notice to Pledgor.

(c) If, at any time when Lender in its sole discretion determines, following the occurrence and during the continuance of an Event of Default, that, in connection with any actual or contemplated exercise of its rights (when permitted under this Section 8) to sell the whole or any part of the Pledged Shares hereunder, it is necessary or advisable to effect a public registration of all or part of the Pledged Collateral pursuant to the Securities Act of 1933, as amended (or any similar statute then in effect) (the “Act”), Pledgor shall, in an expeditious manner, cause the Pledged Entities to:

(i) Prepare and file with the Securities and Exchange Commission (the “Commission”) a registration statement with respect to the Pledged Shares and in good faith use commercially reasonable efforts to cause such registration statement to become and remain effective;

(ii) Prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective and to comply with the provisions of the Act with respect to the sale or other disposition of the Pledged Shares covered by such registration statement whenever Lender shall desire to sell or otherwise dispose of the Pledged Shares;

(iii) Furnish to Lender such numbers of copies of a prospectus and a preliminary prospectus, in conformity with the requirements of the Act, and such other documents as Lender may request in order to facilitate the public sale or other disposition of the Pledged Shares by Lender;

(iv) Use commercially reasonable efforts to register or qualify the Pledged Shares covered by such registration statement under such other securities or blue sky laws of such jurisdictions within the United States and Puerto Rico as Lender shall request, and do such other reasonable acts and things as may be required of it to enable Lender to consummate the public sale or other disposition in such jurisdictions of the Pledged Shares by Lender;

(v) Furnish, at the request of Lender, on the date that shares of the Pledged Collateral are delivered to the underwriters for sale pursuant to such registration or, if the security is not being sold through underwriters, on the date that the registration statement with respect to such Pledged Shares becomes effective, (A) an opinion, dated such date, of the independent counsel representing such registrant for the purposes of such registration, addressed to the underwriters, if any, and in the event the Pledged Shares are not being sold through underwriters, then to Lender, in customary form and covering matters of the type customarily covered in such legal opinions; and (B)a comfort letter, dated such date, from the independent certified public accountants of such registrant, addressed to the underwriters, if any, and in the event the Pledged Shares are not being sold through underwriters, then to Lender, in a customary form and covering matters of the type customarily covered by such comfort letters and as the underwriters or Lender shall reasonably request. The opinion of counsel referred to above shall additionally cover such other legal matters with respect to the registration in respect of which such opinion is being given as Lender may reasonably request. The letter referred to above from the independent certified public accountants shall additionally cover such other financial matters (including information as to the period ending not more than five (5) Business Days prior to the date of such letter) with respect to the registration in respect of which such letter is being given as Lender may reasonably request; and

(vi) Otherwise use commercially reasonable efforts to comply with all applicable rules and regulations of the Commission, and make available to its security holders, as soon as reasonably practicable but not later than 18 months after the effective date of the registration statement, an earnings statement covering the period of at least 12 months beginning with the first full month after the effective date of such registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Act.

(d) All expenses incurred in complying with Section 8(c) hereof, including, without limitation, all registration and filing fees (including all expenses incident to filing with the National Association of Securities Dealers, Inc.), printing expenses, fees and disbursements of counsel for the registrant, the fees and expenses of counsel for Lender, expenses of the independent certified public accountants (including any special audits incident to or required by any such registration) and expenses of complying with the securities or blue sky laws or any jurisdictions, shall be paid by Pledgor.

(e) If, at any time when Lender shall determine to exercise its right to sell the whole or any part of the Pledged Collateral hereunder, such Pledged Collateral or the part thereof to be sold shall not, for any reason whatsoever, be effectively registered under the Securities Act of 1933, as

amended (or any similar statute then in effect) (the “Act”)/the Act, Lender may, in its discretion (subject only to applicable requirements of law), sell such Pledged Collateral or part thereof by private sale in such manner and under such circumstances as Lender may deem necessary or advisable, but subject to the other requirements of this Section 8, and shall not be required to effect such registration or to cause the same to be effected. Without limiting the generality of the foregoing, in any such event, Lender in its discretion (i) may, in accordance with applicable securities laws, proceed to make such private sale notwithstanding that a registration statement for the purpose of registering such Pledged Collateral or part thereof could be or shall have been filed under said Act (or similar statute), (ii) may approach and negotiate with a single possible purchaser to effect such sale, and (iii) may restrict such sale to a purchaser who is an accredited investor under the Act and who will represent and agree that such purchaser is purchasing for its own account, for investment and not with a view to the distribution or sale of such Pledged Collateral or any part thereof. In addition to a private sale as provided above in this Section 8, if any of the Pledged Collateral shall not be freely distributable to the public without registration under the Act (or similar statute) at the time of any proposed sale pursuant to this Section 8, then Lender shall not be required to effect such registration or cause the same to be effected but, in its discretion (subject only to applicable requirements of law), may require that any sale hereunder (including a sale at auction) be conducted subject to restrictions:

(A) as to the financial sophistication and ability of any Person permitted to bid or purchase at any such sale;

(B) as to the content of legends to be placed upon any certificates representing the Pledged Collateral sold in such sale, including restrictions on future transfer thereof;

(C) as to the representations required to be made by each Person bidding or purchasing at such sale relating to that Person’s access to financial information about Pledgor and such Person’s intentions as to the holding of the Pledged Collateral so sold for investment for its own account and not with a view to the distribution thereof; and

(D) as to such other matters as Lender may, in its discretion, deem necessary or appropriate in order that such sale (notwithstanding any failure so to register) may be effected in compliance with the Bankruptcy Code and other laws affecting the enforcement of creditors’ rights and the Act and all applicable state securities laws.

(f) Pledgor recognizes that Lender may be unable to effect a public sale of any or all the Pledged Collateral and may be compelled to resort to one or more private sales thereof in accordance with clause (e) above. Pledgor also acknowledges that any such private sale may result in prices and other terms less favorable to the seller than if such sale were a public sale and, notwithstanding such circumstances, agrees that any such private sale shall not be deemed to have been made in a commercially unreasonable manner solely by virtue of such sale being private. 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 Pledged Entity to register such securities for public sale under the Act, or under applicable state securities laws, even if Pledgor and the Pledged Entity would agree to do so.

(g) Pledgor agrees to the maximum extent permitted by applicable law that following the

occurrence and during the continuance of an Event of Default it will not at any time plead, claim or take the benefit of any appraisal, valuation, stay, extension, moratorium or redemption law now or hereafter in force in order to prevent or delay the enforcement of this Agreement, or the absolute sale of the whole or any part of the Pledged Collateral or the possession thereof by any purchaser at any sale hereunder, and Pledgor waives the benefit of all such laws to the extent it lawfully may do so. Pledgor agrees that it will not interfere with any right, power and remedy of Lender provided for in this Agreement or now or hereafter existing at law or in equity or by statute or otherwise, or the exercise or beginning of the exercise by Lender of any one or more of such rights, powers or remedies. No failure or delay on the part of Lender to exercise any such right, power or remedy and no notice or demand which may be given to or made upon Pledgor by Lender with respect to any such remedies shall operate as a waiver thereof, or limit or impair Lender’s right to take any action or to exercise any power or remedy hereunder, without notice or demand, or prejudice its rights as against Pledgor in any respect.

(h) Pledgor further agrees that a breach of any of the covenants contained in this Section 8 will cause irreparable injury to Lender, that Lender shall have no adequate remedy at law in respect of such breach and, as a consequence, agrees that each and every covenant contained in this Section 8 shall be specifically enforceable against Pledgor, and Pledgor hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants except for a defense that the Obligations are not then due and payable in accordance with the agreements and instruments governing and evidencing such obligations.

9. Waiver. 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 by Lender with respect to any power of sale, Lien, option or other right hereunder, shall constitute a waiver thereof, or limit or impair Lender’s right to take any action or to exercise any power of sale, Lien, option, or any other right hereunder, without notice or demand, or prejudice Lender’s rights as against Pledgor in any respect.

10. Assignment. Lender may assign, indorse or transfer any instrument evidencing all or any part of the Obligations as provided in, and in accordance with, the Loan Agreement, and the holder of such instrument shall be entitled to the benefits of this Agreement.

11. Termination. Immediately following the Termination Date, Lender shall deliver to Pledgor the Pledged Collateral pledged by Pledgor at the time subject to this Agreement and all instruments of assignment executed in connection therewith, free and clear of the Liens hereof and, except as otherwise provided herein, all of Pledgor’s obligations hereunder shall at such time terminate.

12. Lien Absolute. All rights of Lender hereunder, and all obligations of Pledgor hereunder, shall be absolute and unconditional irrespective of:

(a) any lack of validity or enforceability of the Loan Agreement, any other Loan Document or any other agreement or instrument governing or evidencing any Obligations;

(b) any change in the time, manner or place of payment of, or in any other term of, all or any part of the Obligations, or any other amendment or waiver of or any consent to any departure

from the Loan Agreement, any other Loan Document or any other agreement or instrument governing or evidencing any Obligations;

(c) any exchange, release or n n perfection of any other Collateral, or any release or amendment or waiver of or consent to departure from any guaranty, for all or any of the Obligations;

(d) the insolvency of any Credit Party; or

(e) any other circumstance which might otherwise constitute a defense available to, or a discharge of, Pledgor.

13. Release. Pledgor consents and agrees that Lender may at any time, or from time to time, in its discretion:

(a) renew, extend or change the time of payment, and/or the manner, place or terms of payment of all or any part of the Obligations; and

(b) exchange, release and/or surrender all or any of the Collateral (including the Pledged Collateral), or any part thereof, by whomsoever deposited, which is now or may hereafter be held by Lender in connection with all or any of the Obligations; all in such manner and upon such terms as Lender may deem proper, and without notice to or further assent from Pledgor, it being hereby agreed that Pledgor shall be and remain bound upon this Agreement, irrespective of the value or condition of any of the Collateral, and notwithstanding any such change, exchange, settlement, compromise, surrender, release, renewal or extension, and notwithstanding also that the Obligations may, at any time, exceed the aggregate principal amount thereof set forth in the Loan Agreement, or any other agreement governing any Obligations. Pledgor hereby waives notice of acceptance of this Agreement, and also presentment, demand, protest and notice of dishonor of any and all of the Obligations, and promptness in commencing suit against any party hereto or liable hereon, and in giving any notice to or of making any claim or demand hereunder upon Pledgor. No act or omission of any kind on Lender’s part shall in any event affect or impair this Agreement.

14. Reinstatement. This Agreement shall remain in full force and effect and continue to be effective should any petition be filed by or against Pledgor or any Pledged Entity for liquidation or reorganization, should Pledgor or any Pledged Entity become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of Pledgor’s or a Pledged Entity’s assets, and shall continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Obligations, or any part thereof, is, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee of the Obligations, whether as a “voidable preference”, “fraudulent conveyance”, or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Obligations shall be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

15. Miscellaneous.

(a) Lender may execute any of its duties hereunder by or through agents or employees

and shall be entitled to advice of counsel concerning all matters pertaining to its duties hereunder.

(b) Pledgor agrees to promptly reimburse Lender for actual out of pocket expenses, including, without limitation, reasonable counsel fees, incurred by Lender in connection with the administration and enforcement of this Agreement.

(c) Neither Lender, nor any of its respective officers, directors, employees, agents or counsel shall be liable for any action lawfully taken or omitted to be taken by it or them hereunder or in connection herewith, except for its or their own gross negligence or willful misconduct as finally determined by a court of competent jurisdiction.

(d) THIS AGREEMENT SHALL BE BINDING UPON PLEDGOR AND ITS SUCCESSORS AND ASSIGNS (INCLUDING A DEBTOR IN POSSESSION ON BEHALF OF PLEDGOR), AND SHALL INURE TO THE BENEFIT OF, AND BE ENFORCEABLE BY, LENDER AND ITS SUCCESSORS AND ASSIGNS, AND SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF CONNECTICUT APPLICABLE TO CONTRACTS MADE AND PERFORMED IN THAT STATE, AND NONE OF THE TERMS OR PROVISIONS OF THIS AGREEMENT MAY BE WAIVED, ALTERED, MODIFIED OR AMENDED EXCEPT IN WRITING DULY SIGNED FOR AND ON BEHALF OF LENDER AND PLEDGOR.

16. Severability. If for any reason any provision or provisions hereof are determined to be invalid and contrary to any existing or future law, such invalidity shall not impair the operation of or effect those portions of this Agreement which are valid.
