Unless and until a Default or an Event of Default shall have occurred, and until notice of such Default or Event of Default has been given by the Pledgee, the Pledgor shall be entitled to receive all regular cash dividends paid in respect of the Stock, to vote the Stock and to give consents, waivers and ratifications in respect of the Stock; provided, however, that no vote shall be cast, or consent, waiver or ratification given or action taken which would be inconsistent with or violate any provisions of any of this Agreement, the Stockholder Agreement, the Pledgor Note or any agreement, instrument or other document executed or required to be executed pursuant hereto or thereto. Until the occurrence of a Default or an Event of Default, the Pledgee shall pay over to the Pledgor, forthwith upon receipt, all regular cash dividends paid on the Stock, and shall execute and deliver to the Pledgor such proxies or other documents in writing as may be necessary to enable the Pledgor to exercise the foregoing rights. All such rights of the Pledgor to receive regular cash dividends on the Stock, to vote and give consents, waivers and ratifications shall cease forthwith in case a Default or an Event of Default shall have occurred, without any notice (except as provided in this Section) or demand by the Pledgee to the Pledgor. Section 6. Remedies. If a Default or an Event of Default shall have occurred, the Pledgee shall thereafter have the following rights and remedies (to the maximum extent permitted by applicable law) in addition to the rights and remedies of a secured party under the Uniform Commercial Code of The Commonwealth of Massachusetts all such rights and remedies being cumulative, not exclusive, and enforceable alternatively, successively or concurrently, at such time or times as the Pledgee, in its sole and absolute discretion, deems expedient: (a) The Pledgee may vote any or all shares of the Stock (whether or not the same shall have been transferred into its name or the name of its nominee or nominees) and give all consents, waivers and ratifications in respect of the Stock and otherwise act with respect thereto as though it were the outright owner thereof (the Pledgor hereby irrevocably constituting and appointing the Pledgee the proxy and attorney-in-fact of the Pledgor, with full power of substitution, to do so); (b) The Pledgee may demand, sue for, collect or make any compromise or settlement the Pledgee deems suitable in respect of any Collateral held by it hereunder; (c) The Pledgee may sell, assign or otherwise Transfer any or all of the Collateral, for cash and upon such terms, at such place or places and at such time or times and to such Persons as the Pledgee, in its sole and absolute discretion, deems expedient, all without demand for performance by the Pledgor or any notice or advertisement whatsoever except such as may be required by applicable law; and (d) The Pledgee may cause all or any part of the Stock held by it to be transferred into its name or the name of its nominee or nominees. The Pledgee may buy any part or all of the Collateral at any public sale and if any part or all of the Collateral is of a type customarily sold in a recognized market or is of the type which is the subject of widely-distributed standard price quotations, the Pledgee may, in its sole and absolute discretion, buy at private sale and may make payments therefor by any means including, without limitation, cancellation, in 3 whole or in part, of any of the Obligations secured thereby. The Pledgee may, in its sole and absolute discretion, apply the cash proceeds actually received from any sale or other disposition to the reasonable expenses of retaking, holding, preparing for sale, selling and the like, to reasonable attorneys fees, and all legal expenses, travel and other expenses which may be incurred by the Pledgee in attempting to collect the Obligations or to enforce this Agreement, the Stockholder Agreement or any agreement, instrument or other document executed or required to be executed pursuant hereto or thereto or any agreement, instrument or other document evidencing the Obligations or in the prosecution or defense of any legal action, litigation or other proceeding related to the subject matter of this Agreement, the Stockholder Agreement or any agreement, instrument or other document executed or required to be executed pursuant hereto or thereto or any agreement, instrument or other document evidencing the Obligations, and then to the Obligations with respect to principal or interest, or both, or other fees and expenses, in such proportions as the Pledgee, in its sole and absolute discretion, shall determine; and any surplus shall be paid to the Pledgor. The Pledgor recognizes that the Pledgee may be unable to effect a public sale of the Stock by reason of certain prohibitions contained in federal or state securities laws or other applicable laws, or agreement, instrument or other documents to which such Stock may be subject, but may be compelled to resort to one or more private sales thereof to a restricted group of purchasers. The Pledgor agrees that any such private sales may be at prices and other terms less favorable to the seller than if sold at public sales and that such private sales shall be deemed to have been made in a commercially reasonable manner. The Pledgee shall be under no obligation to delay a sale of any of the Stock for the period of time necessary to permit the issuer of such securities to register such securities for public sale under federal and state securities laws or other applicable law, even if the issuer would agree to do so. Section 7. Marshalling. The Pledgee shall not be required to marshal any present or future security for (including without limitation this Agreement and the Collateral pledged hereunder), or guaranties of, the Obligations or any of them, or to resort to such security or guaranties in any particular order; and all of the rights hereunder and in respect of such security and guaranties shall be cumulative and in addition to all other rights, however existing or arising. To the maximum extent permitted by applicable law, the Pledgor hereby agrees that it will not invoke any law relating to the marshalling of collateral which might cause delay in or impede the enforcement of the Pledgee's rights under this Agreement, the Stockholder Agreement or any agreement, instrument or other document executed or required to be executed pursuant hereto or thereto or under any other agreement, instrument or other document evidencing any of the Obligations or under which any of the Obligations is outstanding or by which any of the Obligations is secured or guaranteed, and, to the maximum extent permitted by applicable law, the Pledgor hereby irrevocably waives the benefits of all such laws. Section 8. Pledgor's Obligations Not Affected. The obligations of the Pledgor hereunder shall remain in full force and effect without regard to, and shall not be impaired by (a) any bankruptcy, insolvency, reorganization, arrangement, readjustment, composition, dissolution, liquidation or other Act of Bankruptcy (or legal action, litigation or other proceeding with respect to any of the foregoing) of the Pledgor; (b) any exercise or non-exercise, or any waiver, by the Pledgee of any right, remedy, power or privilege under or in respect of any of the Obligations or any security therefor (including this Agreement); or (c) the taking of additional security for, or any guaranty of, any of the Obligations or the release or discharge or termination of any other security or guaranty for any of the Obligations; whether or not the Pledgor shall have notice or knowledge of any of the foregoing. Section 9. Pledgee's Exoneration. Under no circumstances shall the Pledgee be deemed to assume any responsibility for or obligation or duty with respect to any part or all of the Collateral of any nature or kind, or any matter or legal action, litigation or other proceeding arising out, of or relating thereto, but the same shall be at the Pledgor's sole and exclusive risk at all times. The Pledgee shall not 4 be required to take or refrain from taking any action of any kind to collect, preserve or protect its or the Pledgor's rights in the Collateral or against other parties thereto. The Pledgee's prior recourse to any part or all of the Collateral shall not constitute a condition of any demand or legal action, litigation or other proceeding for payment or collection of the Obligations. Section 10. Termination. Upon payment and performance in full of the Obligations in accordance with their terms and the performance by the Pledgor of all of its covenants and agreements hereunder, this Agreement shall terminate, and the Pledgor shall be entitled to the return, at the Pledgor's expense, of such of the Collateral in the possession or control of the Pledgee as has not theretofore been disposed of pursuant to the provisions hereof, together with any monies and other property at the time held by the Pledgee hereunder. If at any time any payment made in respect of the Obligations shall be recovered or rescinded by or on behalf of Pledgor or must be otherwise restored or returned, whether upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of Pledgor, or as a result of the appointment of a receiver, conservator of or trustee or similar officer for Pledgor or any substantial part of it property, any other Act of Bankruptcy, or otherwise, Pledgor's obligations under this Agreement shall be reinstated and continue as though such payment had not been made. Section 11. Further Assurances. The Pledgor will do all such acts, and will furnish to the Pledgee all such financing documents, financing statements, certificates, legal opinions and other agreement, instrument or other documents and will obtain all such governmental authorizations and other consents and approvals and will do or cause to be done all such other things, including without limitation the execution and delivery of further agreement, instrument or other documents, as Pledgee may reasonably request from time to time in order to give full force and effect to this Agreement and to secure Pledgee's rights hereunder. Without limiting the generality of the foregoing, Pledgor agrees to deliver to Pledgee, from time to time at the request of Pledgee, such financial information relating to Pledgor as Pledgee may from time to time reasonably request, including, without limitation, personal balance sheets of Pledgor, certified by Pledgor to be true, correct and complete. Pledgor authorizes Pledgee to file any financing statement deemed by Pledgee, in its sole and absolute discretion, to be necessary or desirable to perfect the security interest granted by Pledgor to Pledgee, and, as agent for Pledgor, to sign the name of Pledgor thereto.

Any consent may be given subject to satisfaction of conditions stated therein.

If any provision of this Agreement shall be held or deemed to be, or shall in fact be, invalid, inoperative, illegal or unenforceable as applied to any particular case in any jurisdiction or jurisdictions, or in all jurisdictions or in all cases, because of the conflict of any provision with any constitution or statute or rule of public policy or for any other reason, such circumstance shall not have the effect of rendering the provision or provisions in question invalid, inoperative, illegal or unenforceable in any other jurisdiction or in any other case or circumstance or of rendering any other provision or provisions herein contained invalid, inoperative, illegal or unenforceable to the extent that such other provisions are not themselves actually in conflict with such constitution, statute or rule of public policy, but this Agreement shall be reformed and construed in any such jurisdiction or case as if such invalid, inoperative, illegal or unenforceable provision had never been contained herein and such provision reformed so that it would be valid, operative and enforceable to the maximum extent permitted in such jurisdiction or in such case. Notwithstanding the foregoing, in the event of any such determination the effect of which is to affect materially and adversely any party, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible to the fullest extent permitted by Applicable Law in an acceptable manner to the end that the transactions contemplated by this Agreement are fulfilled and consummated to the maximum extent possible.
