---

-3-

of the Agent or any third party acting on its behalf (including without
limitation the Custodian), or otherwise, including but not limited to (i) any deposit or
other balance of account standing to the credit of such Pledgor on the books of the
Agent, regardless of whether for the express purpose of being used by the Agent as
collateral security or for safekeeping or for any other or different purposes, including
property in transit or covered or affected by documents in the Agents possession or
control, (ii) rights to receive any security, interests or other property, (iii) all cash
and cash equivalents and all interest and other income therefrom and (iv) all books and
records pertaining to any of the property referred to in this Section 2, and

c.
the proceeds and accessions and all collateral security and guarantees given by any
person with respect to any of the property described in clauses (a) and (b) above,

3. Representations and
Warranties. Each of the Pledgors hereby represents and warrants to the Agent and the
Banks that:

| | a.
such Pledgor is the entitlement holder of the Collateral that is held in the Securities
Accounts and there are no restrictions on the pledge or transfer of any of the Collateral;
| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | b.
all the Collateral, where applicable, has been duly and validly issued and is fully paid
and nonassessable;
| | --------------------------------------------------------------------------------------------------------------

| | c.
     except for the pledge and security interest granted hereby or subordinate liens
     of the Custodian permitted by the applicable Control Agreement, (i) the
     Collateral is free and clear of any security interests, pledges, liens,
     encumbrances, charges, agreements, claims or other arrangements or restrictions
     of any kind, and (ii) such Pledgor will not incur, create, assume or permit to
     exist any pledge, security interest, lien, charge or other encumbrance of any
     nature whatsoever on any of the Collateral or assign, pledge or otherwise
     encumber any right to receive income from the Collateral;
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | d.
the chief executive office of such Pledgor is set forth on Schedule I hereto;
| | --------------------------------------------------------------------------------

| | e.
     such Pledgor has the right to transfer the Collateral free of any encumbrances
     and such Pledgor will defend such Pledgors title to the Collateral against
     the claims of all persons, and any registration with, or consent or approval of,
     or other action by, any federal, state or other governmental authority or
     regulatory body which was or is necessary for the validity of the pledge of and
     grant of the security interest in the Collateral has been obtained; and
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | f.
     the pledge of and grant of the security interest in the Collateral under this
     Pledge Agreement, together with the execution of the applicable Control
     Agreement by the parties thereto, is effective to vest in the Agent for the
     ratable benefit of the Issuing Bank and
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

---

-4-

| | the Banks a valid and perfected first
     priority security interest in and to the Collateral as set forth herein
     enforceable against all creditors of such Pledgor.
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------

4.
Covenants. The Pledgors shall maintain, or cause the Custodian to
maintain, at all times in the Securities Accounts as financial assets (within
the meaning of the Code), sufficient Eligible Collateral to meet the
requirements of Section 2.14 of the Credit Agreement. Except as set forth in
Section 7 hereof or in the Control Agreement, no withdrawal of Collateral from
the Securities Accounts shall be permitted or made without the prior written
consent of the Agent. The obligations of the Pledgors hereunder shall remain
full force and effect without regard to, and shall not be impaired by (i) any
exercise or nonexercise, or any waiver, by the Agent of any right, remedy, power
or privilege under or in respect of any of the Obligations or any security
therefor (including this Agreement); (ii) any amendment to or modification of
the Credit Agreement, the other Credit Documents or any of the Obligations;
(iii) any amendment to or modification of any instrument (other than this
Agreement) securing any of the Obligations, including, without limitation, any
of the Credit Documents; or (iv) the taking of additional security for, or any
other assurances of payment of, any of the Obligations or the release or
discharge or termination of any security or other assurances of payment or
performance for any of the Obligations; whether or not the Pledgors shall have
notice or knowledge of any of the foregoing, the Pledgors hereby generally
waiving all suretyship defenses to the extent applicable.

5. Default; Remedies.

5.1.
If any of the following occur (each an Event of Default): (i) any
Event of Default under the Credit Agreement or any other Credit Document, (ii) the
failure by any of the Pledgors to perform any of its obligations hereunder, (iii) the
falsity, inaccuracy or material breach by any of the Pledgors of any covenant, warranty,
representation or statement made or furnished to the Agent by or on behalf of such
Pledgor, (iv) the failure of the Agent to have a perfected first priority security
interest in the Collateral (other than to the extent caused solely by the action or
inaction of the Agent), (v) any restriction is imposed on the pledge or transfer of any
of the Collateral after the date of this Agreement without the prior written consent of
the Agent, or (vi) the breach of any of the Control Agreements, or receipt of notice of
termination of any of the Control Agreements if no successor custodian reasonably
acceptable to the Agent has executed a replacement Control Agreement, then the Agent is
authorized in its discretion to exercise any one or more of the rights and remedies
granted pursuant to this Pledge Agreement or given to a secured party under the Code or
otherwise at law or in equity, including without limitation the right to sell or
otherwise dispose of any or all of the Collateral at public or private sale, with or
without advertisement thereof, upon such terms and conditions as it may deem advisable
and at such prices as it may deem best.

5.2.
(a) At any bona fide public sale, and to the extent permitted by law, at any private
sale, the Agent or any Bank shall be free to purchase all or any part of the Collateral,
free of any right or equity of redemption in the Pledgors, which right or equity is
hereby waived and released. Any such sale may be on cash or credit. The Agent will not be
obligated to make any sale if it determines not to do so, regardless of the fact that
notice of the sale may have been given. The Agent may adjourn any sale and sell at the
time and place to which the sale is adjourned. If the Collateral is customarily sold on a
recognized market or threatens to decline speedily in value, the

---

-5-

Agent may sell such Collateral at any time without giving prior notice to the
Pledgors. Whenever notice is otherwise required by law to be sent by the Agent to the
Pledgors of any sale or other disposition of the Collateral, five (5) days written notice
sent to the Pledgors at the address specified on Schedule I hereto will be reasonable.
The Agent may buy any part or all of the Collateral at any public sale and, with respect
to any part or all of the Collateral that 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 Agent may buy at private sale and may make payments thereof by any means.

(b)
The Pledgors recognize that the Agent may be unable to effect or cause to be effected a
public sale of the Collateral by reason of certain prohibitions contained in the
Securities Act of 1933, as amended (the Act), so that the Agent may be
compelled to resort to one or more private sales to a restricted group of purchasers who
will be obligated to agree, among other things, to acquire the Collateral for their own
account, for investment and not with a view to the distribution or resale thereof. The
Pledgors understand that private sales so made may be at prices and on other terms less
favorable to the seller than if the Collateral were sold at public sales, and agrees that
the Agent has no obligation to delay or agree to delay the sale of any of the Collateral
for the period of time necessary to permit the issuer of the securities which are part of
the Collateral (even if the issuer would agree), to register such securities for sale
under the Act. The Pledgors agree that private sales made under the foregoing
circumstances shall be deemed to have been made in a commercially reasonable manner.

5.3.
The net proceeds arising from the disposition of the Collateral as provided herein, after
deducting expenses incurred by the Agent will be applied to the Obligations and the costs
and expenses incurred by the Agent in enforcing this Pledge Agreement in the order
determined by the Agent. If any excess remains after the discharge of all of the
Obligations, the same will be paid to the Pledgors. If after exhausting all of the
Collateral there is a deficiency, the Pledgors will be liable therefor to the Agent and
the Banks; provided, however, that nothing contained herein will obligate
the Agent to proceed against any other party obligated under the Obligations or against
any other collateral for the Obligations prior to proceeding against the Collateral.

5.4.
If any demand is made at any time upon the Agent or any Bank for the repayment or
recovery of any amount received by it in payment or on account of any of the Obligations
or such Bank from the disposition of the Collateral and if the Agent or such Bank repays
all or any part of such amount, the Pledgors will be and remain liable for the amounts so
repaid or recovered to the same extent as if never originally received by the Agent or
such Bank.

6. Voting Rights and
Entitlement Orders.

| | a.
     Prior to the occurrence of an Event of Default, notwithstanding anything in the
     Control Agreements to the contrary, (i) the Agent shall not issue any
     entitlement orders or other instructions to the Custodian with respect to the
     Securities Accounts or the Collateral (except in connection with withdrawals
     from the Securities Accounts requested by the Pledgors and approved by the
     Agent) and (ii) the Pledgors will have the right to exercise all voting and
     consensual rights with respect to the Collateral.
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

---

-6-

| | b.
     At any time after the occurrence of an Event of Default, the Agent may issue
     such entitlement orders and instructions as it may in its discretion elect, may
     transfer any or all of the Collateral into its name or that of its nominee and
     may exercise all voting rights with respect to the Collateral, but no such
     transfer shall constitute a taking of such Collateral in satisfaction of any or
     all of the Obligations unless the Agent expressly so indicates by written notice
     to the Pledgors.
| | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

7. Dividends,
Distributions, Interest and Premiums. Prior to the occurrence of any Event
of Default, notwithstanding anything in the Control Agreements to the contrary,
the Pledgors will have the right to withdraw from the Securities Accounts and
receive free and clear of the Agents security interest hereunder (i) all
cash dividends, distributions, interest and premiums declared and paid on the
Collateral and (ii) any portion of the Collateral if the Discounted Collateral
Value is greater than 105% of the Letter of Credit Exposure (as defined in the
Credit Agreement) all as more fully set forth in Section 2.14 of the Credit
Agreement. Prior to the occurrence of any Event of Default, notwithstanding
anything in the Control Agreements to the contrary, the Pledgors shall be
permitted to make substitutions of Collateral provided that the Discounted
Collateral Value of the Collateral is at least equal to that of the Collateral
for which it is substituted. At any time after the occurrence of an Event of
Default, no such withdrawal or substitution shall be permitted and the Agent
shall be entitled to receive all cash or stock dividends, distributions,
interest and premiums declared or paid on the Collateral, all of which shall be
subject to the Agents rights under Section 5 above. In the event any
additional shares are issued to any of the Pledgors as a stock dividend or in
lieu of interest on any of the Collateral, as a result of any split of any of
the Collateral, by reclassification or otherwise, any certificates evidencing
any such additional shares will be immediately delivered to the Custodian and
such shares will be subject to this Pledge Agreement and a part of the
Collateral to the same extent as the original Collateral.

8. Securities Account.
Each of the Pledgors agrees to cause the Custodian to execute and deliver,
contemporaneously herewith, the appropriate Control Agreement in order to protect the
Agent's security interest in the Securities Accounts and the Collateral.

9. Further
Assurances. At any time and from time to time, upon demand of the Agent,
each of the Pledgors will give, execute, file and record any notice, financing
statement, continuation statement, instrument, document or agreement that the
Agent may consider necessary or desirable to create, preserve, continue, perfect
or validate any security interest granted hereunder or to enable the Agent to
exercise or enforce its rights hereunder with respect to such security interest.
Without limiting the generality of the foregoing, each of the Pledgors hereby
irrevocably appoints the Agent as such Pledgors attorney-in-fact to do all
acts and things in such Pledgors name that the Agent may deem necessary or
desirable to perfect or enforce its security interest hereunder. This power of
attorney is coupled with an interest with full power of substitution and is
irrevocable. The Agent is authorized at any time and from time to time to file
financing statements, continuation statements and other documents under the Code
relating to the Collateral without such Pledgors signature, naming such
Pledgor as debtor and the Agent as secured party. The Agent is further
authorized at any time and from time to time to file in any filing office in any
Uniform Commercial Code jurisdiction any initial financing statements and
amendments thereto that contain any information

---

-7-

required by part 5 of Article 9 of the Uniform Commercial Code of the jurisdiction of the filing office for the
sufficiency or filing office acceptance of any financing statement or amendment,
including whether any Pledgor is an organization, the type of organization and any
organization identification number issued to such Pledgor. Each Pledgor agrees to furnish
any such information to the Agent promptly upon request.

10.
Limitation on Duties Regarding Collateral. The Agents sole duty
with respect to the custody, safekeeping and physical preservation of the
Collateral in its possession, under Section 9-207 of the Code or otherwise,
shall be to deal with it in the same manner as the Agent deals with similar
securities and property for its own account. Neither any holder of any
Obligation nor any of its respective directors, officers, employees or agents
shall be liable for any 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 Pledgors or
otherwise.

11. Powers Coupled with
an Interest. All authorizations and agencies herein contained with respect to the
Collateral are irrevocable and powers coupled with an interest.

12.
Severability. Any provision of this Pledge Agreement which is prohibited
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provisions in any other jurisdiction.

13. Section Headings. The
section headings used in this Pledge Agreement are for convenience of reference only and
are not to affect the construction hereof or be taken into consideration in the
interpretation hereof.

14. No
Waiver; Cumulative Remedies. No holder of any Obligation shall by any act
(except by a written instrument pursuant to Section 16 hereof) be deemed to have
waived any right or remedy hereunder or to have acquiesced in any default of any
obligation under any Loan Document or in any breach of any of the terms and
conditions hereof or thereof. No failure to exercise, nor any delay in
exercising, on the part of any holder of any Obligation of any right, power or
privilege hereunder shall operate as a waiver thereof. No single or partial
exercise of any right, power or privilege hereunder shall preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
A waiver by any holder of any Obligation of any right or remedy hereunder on any
one occasion shall not be construed as a bar to any right on any future
occasion. The rights and remedies herein provided are cumulative, may be
exercised singly or concurrently and are not exclusive of any other rights or
remedies provided by law.

15. Waivers
and Amendments; Successors and Assigns; Governing Law. None of the terms or
provisions of this Pledge Agreement may be amended, supplemented or otherwise
modified except by a written instrument executed by the Pledgors and the Agent,
provided that any provision of this Pledge Agreement may be waived by the
Agent in a letter or agreement executed by the Agent or by telex or facsimile
transmission from the Agent. This Pledge Agreement shall be binding

---

-8-

upon the
respective heirs, administrators, successors and assigns of the Pledgors and
shall inure to the benefit of the holder of the Obligations and their respective
successors and assigns. THIS PLEDGE AGREEMENT IS INTENDED TO TAKE EFFECT AS A
SEALED INSTRUMENT AND SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH,
THE SUBSTANTIVE LAWS OF THE COMMONWEALTH OF MASSACHUSETTS.

16.
Notices. All notices hereunder to the Agent or the Pledgors to be
effective shall be in writing (including by telecopy), and, unless otherwise
expressly provided herein, shall be deemed to have been duly given when
delivered or sent in the manner and to the respective addresses as provided in
the Credit Agreement.

17.
Irrevocable Authorization and Instruction. Each of the Pledgors hereby
authorizes and instructs the Custodian to comply with any instruction received
by it from the Agent in writing that (a) states that an Event of Default has
occurred and is continuing and (b) is otherwise in accordance with the terms of
this Pledge Agreement or the Control Agreement, without any other or further
instructions from such Pledgor, and such Pledgor agrees that the Custodian shall
be fully protected in so complying. Each of the Pledgors hereby instructs the
Custodian to mark its records to reflect the pledge of the Collateral and to
take such other action as may be required or customary to effect or evidence the
pledge of the Collateral made and intended to be made pursuant to this Pledge
Agreement.

18. Authority
of Agent. Each of the Pledgors acknowledges that the rights and
responsibilities of the Agent under this Pledge Agreement with respect to any
action taken by the Agent or the exercise or non-exercise by the Agent of any
option, voting right, request, judgment or other right or remedy provided for
herein or resulting or arising out of this Pledge Agreement shall, as between
the Agent and the Banks, be governed by the Credit Agreement and by such other
agreements with respect thereto as may exist from time to time among them, but,
as between the Agent and such Pledgor, the Agent shall be conclusively presumed
to be acting as the holder of the Obligations and on behalf of the Banks with
full and valid authority so to act or refrain from acting, and neither such
Pledgor nor any Issuer shall be under any obligation, or entitlement, to make
any inquiry respecting such authority.

19.
Termination. Upon satisfaction in full of all Obligations, this Agreement
shall terminate automatically and the Agent shall deliver such notice thereof to
the Custodian as may be required or permitted by the Control Agreements (a)
advising that all of the Obligations secured by the Collateral have been
satisfied and (b) instructing the Custodian to release the Collateral. The Agent
shall execute such documents as may be necessary to evidence the termination of
this Agreement.

20. Submission to

          courts of the State of Connecticut, the
          courts of the United States of America in Massachusetts or Connecticut, and

          waives any objection that it may now or hereafter have to the venue of any such

          brought in an inconvenient court and agrees not to plead or claim the same;
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (iii)
          agrees that service of process in any such action or proceeding may be effected
          by mailing a copy thereof by registered or certified mail (or any substantially
          similar form of mail), postage prepaid, to such Pledgor at its address set forth
          in Schedule I hereto or at such other address of which the Agent shall have been
          notified;
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (iv)
          waives and hereby acknowledges that it is estopped from raising any objection
          based on forum non conveniens, any claim that any of the above-referenced
          courts lack proper venue or any objection that any of such courts lack personal
          jurisdiction over it so as to prohibit such courts from adjudicating any issues
          raised in a complaint filed with such courts against such Pledgor concerning
          this Pledge Agreement;
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (v)
          acknowledges and agrees that the choice of forum contained in this paragraph
          shall not be deemed to preclude the enforcement of any judgment obtained in any

          same in any appropriate jurisdiction;
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (vi)
          waives, to the maximum extent not prohibited by law, any right it may have to
          claim or recover in any legal action or proceeding referred to in this
          subsection any special, exemplary or punitive or consequential damages; and
| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (vii)
          agrees that nothing herein shall affect the right to effect service of process
          in any other manner permitted by law or shall limit the right to sue in any
          other jurisdiction.

WITH THIS PLEDGE AGREEMENT OR ANY TRANSACTION CONTEMPLATED IN ANY OF
SUCH DOCUMENTS. EACH OF THE PLEDGORS ACKNOWLEDGES THAT THE FOREGOING WAIVER
IS KNOWING AND VOLUNTARY.

IN WITNESS
