         SECTION V.  DELIVERY OF PLEDGED COLLATERAL.

         A.   All certificates, agreements or instruments representing or
evidencing the Pledged Collateral, to the extent not previously delivered to the
Trustee, shall  immediately upon receipt thereof by Pledgor be delivered to and
held by or on behalf of the Trustee pursuant hereto.  All Pledged Collateral
shall be in suitable form for transfer by delivery or shall be accompanied by
duly executed instruments of transfer or assignment in blank, all in form and
substance reasonably satisfactory to the Trustee.  The Trustee shall have the
right, at any time upon the occurrence and during the continuance of an Event of
Default, to endorse, assign or otherwise transfer to or to register in the name
of the Trustee or any of its nominees any or all of the Pledged Collateral.  In
addition, the Trustee shall have the right at any time upon the occurrence and
during the continuance of an Event of Default to exchange certificates
representing or evidencing Pledged Collateral for certificates of smaller or
larger denominations.

         B.   If the issuer of Pledged Shares is incorporated in a jurisdiction
which does not permit the use of certificates to evidence equity ownership, then
Pledgor shall, to the extent permitted by applicable law, record such pledge on
the stock register of the issuer, execute any customary stock pledge forms or
other documents necessary or appropriate to complete the pledge and give the
Trustee the right to transfer such Pledged Shares under the terms hereof and
provide to the Trustee an Opinion of Counsel, in form and substance satisfactory
to the Trustee, confirming such pledge.

         SECTION VI.  SUPPLEMENTS, FURTHER ASSURANCES.

         A.   Pledgor agrees that at any time and from time to time, at the
sole cost and expense of Pledgor, Pledgor shall promptly execute and deliver all
further instruments and documents, including, without limitation, supplemental
or additional UCC-1 financing statements, and take all further action that may
be necessary or that the Trustee may reasonably request, in order to perfect and
protect the pledge, security interest and Lien granted or purported to be
granted hereby or to enable the Trustee to exercise and enforce its rights and
remedies hereunder with respect to any Pledged Collateral, and a copy of any
such filing shall be delivered to the Trustee.

         B.   Pledgor shall, upon obtaining any Pledged

                                         -4-



Shares of any Person, promptly (and in any event within five Business Days)
deliver to the Trustee a pledge amendment, duly executed by Pledgor, in
substantially the form of EXHIBIT A hereto (each, a "PLEDGE AMENDMENT"), in
respect of the additional Pledged Shares which are to be pledged pursuant to
this  Agreement, and confirming the attachment of the Lien hereby created on and
in respect of such additional shares.  Pledgor hereby authorizes the Trustee to
attach each Pledge Amendment to this Agreement and agrees that all Pledged
Shares listed on any Pledge Amendment delivered to the Trustee shall for all
purposes hereunder be considered Pledged Collateral.

         SECTION VII.  REPRESENTATIONS, WARRANTIES AND COVENANTS.  Pledgor
represents, warrants and covenants as follows:

         A.   NO LIENS.  Pledgor is, and at the time of any delivery of any
    Pledged Collateral to the Trustee pursuant to Section 5 of this Agreement
    will be, the sole legal and beneficial owner of the Pledged Collateral.
    All Pledged Collateral is on the date hereof, and will be, so owned by
    Pledgor free and clear of any Lien, except for the Lien granted to the
    Trustee pursuant to this Agreement.

         B.   AUTHORIZATION, ENFORCEABILITY.  Pledgor has the requisite
    corporate power, authority and legal right to pledge and grant a security
    interest in all the Pledged Collateral pursuant to this Agreement, and this
    Agreement constitutes the legal, valid and binding obligation of Pledgor,
    enforceable against Pledgor in accordance with its terms, except as
    enforceability may be limited by bankruptcy, insolvency, reorganization,
    moratorium and similar laws relating to or affecting creditors' rights
    generally or by general equitable principles (regardless of whether such
    enforceability is considered in a proceeding in equity or at law).

         C.   NO CONSENTS, ETC.  No consent of any party (including, without
    limitation, stockholders or creditors of Pledgor) and no consent,
    authorization, approval, or other action by, and no notice to or filing
    with, any governmental authority or regulatory body or other Person is
    required (x) for the pledge by Pledgor of the Pledged Collateral pursuant
    to this Agreement or for the execution, delivery or performance of this
    Agreement by Pledgor, or (y) for the exercise by the Trustee of the voting
    or other rights provided for in

                                         -5-



    this Agreement, or (z) for the exercise by the Trustee of the remedies in
    respect of the Pledged Collateral pursuant to this Agreement and except for
    consents, authorizations, approvals and other filings and notices required
    under the  Securities Act or under state or "Blue Sky" securities laws.

         D.   DUE AUTHORIZATION AND ISSUANCE.  All of the Pledged Shares have
    been, and to the extent hereafter issued will be upon such issuance, duly
    authorized and validly issued and fully paid and nonassessable.

         E.   CHIEF EXECUTIVE OFFICE.  Pledgor's chief executive office is
    located at One Riverside Way, Wilton, New Hampshire 03086.  Pledgor shall
    not move its chief executive office except to such new location as Pledgor
    may establish in accordance with the last sentence of this Section 7(e).
    Pledgor shall not establish a new location for its chief executive office
    nor shall it change its name until (i) it shall have given the Trustee not
    less than twenty (20) days' prior written notice of its intention so to do,
    clearly describing such new location or name and providing such other
    information in connection therewith as the Trustee may reasonably request,
    and (ii) with respect to such new location or name, Pledgor shall have
    taken all action reasonably satisfactory to the Trustee to maintain the
    perfection and priority of the security interest of the Trustee for the
    benefit of the Secured Parties in the Pledged Collateral intended to be
    granted hereby.

         F.   DELIVERY OF PLEDGED COLLATERAL; FILINGS.  Pledgor has delivered
    to the Trustee all certificates representing the Pledged Shares and has
    caused to be filed with the Secretary of State of the States of Delaware
    and New Hampshire UCC-1 financing statements evidencing the Lien created by
    this Agreement, and such delivery, filing and pledge of the Pledged
    Collateral pursuant to this Agreement creates a valid and perfected first
    priority security interest in the Pledged Collateral securing the payment
    of the Secured Obligations pursuant to the provisions of the Uniform
    Commercial Code as in effect in any relevant jurisdiction (the "UCC"),
    including, without limitation, the States of Delaware and New Hampshire.
         G.   PLEDGED COLLATERAL.  All information set forth herein, including
    the Schedules annexed hereto, relating to the Pledged Collateral is
    accurate and complete in

                                         -6-



    all material respects.

         H.   NO VIOLATIONS, ETC.  The pledge of the Pledged Collateral
    pursuant to this Agreement does not violate Regulation G, T, U or X of the
    Federal Reserve Board.

         I.   OWNERSHIP OF PLEDGED COLLATERAL.  Except as otherwise permitted
    by the Indenture, Pledgor at all times will be the sole beneficial owner of
    the Pledged Collateral.

         J.   NO OPTIONS, WARRANTS, ETC.  There are no options, warrants,
    calls, rights, commitments or agreements of any character to which Pledgor
    is a party or by which it is bound obligating Pledgor to issue, deliver or
    sell or cause to be issued, delivered or sold, additional Pledged Shares or
    obligating Pledgor to grant, extend or enter into any such option, warrant,
    call, right, commitment or agreement.  There are no voting trusts or other
    agreements or understandings to which Pledgor is a party with respect to
    the voting of the capital stock of any issuer of the Pledged Shares.

         SECTION VIII.  VOTING RIGHTS; DISTRIBUTIONS; ETC.

         A.   So long as no Event of Default shall have occurred and be
continuing:

         (a)  Pledgor shall be entitled to exercise any and all voting and
    other consensual rights pertaining to the Pledged Collateral or any part
    thereof for any purpose not inconsistent with the terms or purpose of this
    Agreement and the Indenture; PROVIDED, HOWEVER, that Pledgor shall not in
    any event exercise such rights in any manner which may have an adverse
    effect on the value of the Pledged Collateral or the security intended to
    be provided by this Agreement.

         (b)  Subject to the terms of the Indenture, Pledgor shall be entitled
    to receive and retain, and to utilize free and clear of the Lien of this
    Agreement, any and all Distributions, but only if and to the extent made in
    accordance with the provisions of the Indenture.

         (c)  The Trustee shall be deemed without further action or formality
    to have granted to Pledgor all necessary consents relating to voting rights
    and shall, if necessary, upon written request of Pledgor and at

                                         -7-



    Pledgor's sole cost and expense, from time to time execute  and deliver (or
    cause to be executed and delivered) to Pledgor all such instruments as
    Pledgor may reasonably request in order to permit Pledgor to exercise the
    voting and other rights which it is entitled to exercise pursuant to
    Section 8(a)(i) hereof and to receive the Distributions which it is
    authorized to receive and retain pursuant to Section 8(a)(ii) hereof.

         B.   Upon the occurrence and during the continuance of a Default or an
Event of Default:

         (a)  All rights of Pledgor to exercise the voting and other consensual
    rights it would otherwise be entitled to exercise pursuant to Section
    8(a)(i) hereof without any action or the giving of any notice shall cease,
    and all such rights shall thereupon become vested in the Trustee, which
    shall thereupon have the sole right to exercise such voting and other
    consensual rights.

         (b)  All rights of Pledgor to receive Distributions which it would
    otherwise be authorized to receive and retain pursuant to Section 8(a)(ii)
    hereof shall cease and all such rights shall thereupon become vested in the
    Trustee, which shall thereupon have the sole right to receive and hold as
    Pledged Collateral such Distributions.

         C.   Pledgor shall, at Pledgor's sole cost and expense, from time to
time execute and deliver to the Trustee appropriate instruments as the Trustee
may reasonably request in order to permit the Trustee to exercise the voting and
other rights which it may be entitled to exercise pursuant to Section 8(b)(i)
hereof and to receive all Distributions which it may be entitled to receive
under Section 8(b)(ii) hereof.

         D.   All Distributions which are received by Pledgor contrary to the
provisions of Section 8(b)(ii) hereof shall be received in trust for the benefit
of the Trustee, shall be segregated from other funds of Pledgor and shall
immediately be paid over to the Trustee as Pledged Collateral in the same form
as so received (with any necessary endorsement).

         SECTION IX.  TRANSFERS AND OTHER LIENS; ADDITIONAL SHARES; PRINCIPAL
OFFICE.

                                         -8-



         A.   Pledgor shall not (i) sell, convey, assign or otherwise dispose
of, or grant any option, right or warrant with respect to, any of the Pledged
Collateral except as  permitted by the Indenture, (ii) create or permit to exist
any Lien upon or with respect to any Pledged Collateral other than the Lien and
security interest granted to the Trustee under this Agreement, or (iii) except
as permitted by the Indenture, permit any issuer of the Pledged Shares to merge,
consolidate or change its legal form, unless all of the outstanding capital
stock of the surviving or resulting corporation or partnership, as the case may
be, is, upon such merger or consolidation, pledged hereunder and no cash,
securities or other property is distributed in respect of the outstanding shares
of any other constituent corporation.

         B.   Pledgor shall (i) not authorize any issuer of the Pledged Shares
to issue any stock or other securities in addition to or in substitution for the
Pledged Shares issued by such issuer, except to Pledgor, and (ii) pledge
hereunder, immediately upon its acquisition (directly or indirectly) thereof,
any and all additional shares of capital stock of the issuer of the Pledged
Shares which are required to be pledged hereunder.

         SECTION X.  REASONABLE CARE.  The Trustee shall be deemed to have
exercised reasonable care in the custody and preservation of the Pledged
Collateral in its possession if such Pledged Collateral is accorded treatment
substantially equivalent to that which the Trustee, in its individual capacity,
accords its own property consisting of similar instruments or interests, it
being understood that neither the Trustee nor any of the Secured Parties shall
have responsibility for (i) ascertaining or taking action with respect to calls,
conversions, exchanges, maturities, tenders or other matters relating to any
Pledged Collateral, whether or not the Trustee or any other Secured Party has or
is deemed to have knowledge of such matters, or (ii) taking any necessary steps
to preserve rights against any Person with respect to any Pledged Collateral.

         SECTION XI.  REMEDIES UPON DEFAULT; DECISIONS RELATING TO EXERCISE OF
REMEDIES.

         A.   If any Event of Default shall have occurred and be continuing,
the Trustee shall have the right, but not the obligation, in addition to other
rights and remedies provided for herein or otherwise available to it to be
exercised in accordance with the terms of, and at the times, if any, specified
in the Indenture, (i) to retain and apply


                                         -9-



the Distributions to the Secured Obligations as provided in  Section 12 hereof,
and (ii) to exercise all the rights and remedies of a secured party on default
under the UCC at that time, and the Trustee may also, in accordance with
applicable law, sell the Pledged Collateral or any part thereof (including,
without limitation, any partial interest in the Pledged Shares) at public or
private sale, at any exchange, broker's board or at any of the Trustee's offices
or elsewhere, for cash, on credit or for future delivery, at commercially
reasonable prices and terms.  The Trustee or any other Secured Party may be the
purchaser of any or all of the Pledged Collateral at any such sale and shall be
entitled, for the purpose of bidding and making settlement or payment of the
purchase price for all or any portion of the Pledged Collateral sold at such
sale, to use and apply any of the Secured Obligations owed to such Person as a
credit on account of the purchase price of any Pledged Collateral payable by
such Person at such sale.  Each purchaser at any such sale shall acquire the
property sold absolutely free from any claim or right on the part of Pledgor,
and Pledgor hereby waives, to the fullest extent permitted by law, all rights of
redemption and/or appraisal which it now has or may at any time in the future
have under any rule of law or statute now existing or hereafter enacted.
Pledgor acknowledges and agrees that, to the extent notice of sale shall be
required by law, ten days notice to Pledgor of the time and place of any public
sale or the time after which any private sale or other intended disposition is
to take place shall constitute reasonable notification of such matters.  The
Trustee shall not be obligated to make any sale of Pledged Collateral regardless
of notice of sale having been given.  The Trustee may adjourn any public or
private sale from time to time by announcement at the time and place fixed
therefor, and such sale may, without further notice, be made at the time and
place to which it was so adjourned.  Pledgor hereby waives, to the fullest
extent permitted by law, any claims against the Trustee arising by reason of the
fact that the price at which any Pledged Collateral may have been sold at such a
private sale was less than the price which might have been obtained at a public
sale, even if the Trustee accepts the first offer received and does not offer
such Pledged Collateral to more than one offeree; PROVIDED, HOWEVER, that the
foregoing shall not release the Trustee from its obligation to sell the Pledged
Collateral (or any part thereof) at prices and terms which are commercially
reasonable.

         B.   Pledgor recognizes that, by reason of certain prohibitions
contained in the Securities Act and applicable


                                         -10-



state securities laws, the Trustee may be compelled, with  respect to any sale
of all or any part of the Pledged Collateral, to limit purchasers to Persons who
will agree, among other things, to acquire the Pledged Collateral for their own
account, for investment and not with a view to the distribution or resale
thereof.  Pledgor acknowledges that any such private sales may be at prices and
on terms less favorable to the Trustee than those obtainable through a public
sale without such restrictions (including, without limitation, a public offering
made pursuant to a registration statement under the Securities Act), and,
notwithstanding such circumstances, agrees that any such private sale shall be
deemed to have been made in a commercially reasonable manner and that the
Trustee shall have no obligation to engage in public sales and no obligation to
delay the sale of any Pledged Collateral for the period of time necessary to
permit the issuer thereof to register it for a form of public sale requiring
registration under the Securities Act or under applicable state securities laws,
even if such issuer would agree to do so.

         C.   If the Trustee determines to exercise its right to sell any or
all of the Pledged Collateral, upon written request, Pledgor shall from time to
time furnish to the Trustee all such information as the Trustee may request in
order to determine the number of securities included in the Pledged Collateral
which may be sold by the Trustee as exempt transactions under the Securities Act
and the rules of the Commission thereunder, as the same are from time to time in
effect.

         D.   Pledgor recognizes that, by reason of certain prohibitions
contained in laws, rules, regulations or orders of any foreign governmental
authority, the Trustee may be compelled, with respect to any sale of all or any
part of the Pledged Collateral, to limit purchasers to those who meet the
requirements of such foreign governmental authority.  Pledgor acknowledges that
any such sales may be at prices and on terms less favorable to the Trustee than
those obtainable through a public sale without such restrictions, and,
notwithstanding such circumstances, agrees that any such restricted sale shall
not be deemed to have been made in a commercially unreasonable manner solely for
such reason and that, except as may be required by applicable law, the Trustee
shall have no obligation to engage in public sales.

         E.   In addition to any of the other rights and remedies hereunder,
the Trustee shall have the right to  institute a proceeding seeking specific
performance in


                                     -11-





connection with any of the agreements or obligations hereunder.

         SECTION XII.  APPLICATION OF PROCEEDS.  The proceeds received by the
Trustee in respect of any sale of, collection from or other realization upon all
or any part of the Pledged Collateral pursuant to the exercise by the Trustee of
its remedies as a secured creditor as provided in Section 11 hereof shall be
applied, together with any other sums then held by the Trustee pursuant to this
Agreement, promptly by the Trustee in the manner set forth in the Indenture.

         SECTION XIII.  EXPENSES.  Pledgor will upon demand pay to the Trustee
the amount of any and all reasonable expenses, including the reasonable fees and
expenses of its outside counsel and the fees and expenses of any experts and
agents which the Trustee may incur in connection with (i) the collection of the
Secured Obligations, (ii) the enforcement and administration of this Agreement,
(iii) the custody or preservation of, or the sale of, collection from, or other
realization upon, any of the Pledged Collateral, (iv) the exercise or
enforcement of any of the rights of the Trustee or any Secured Party hereunder
or (v) the failure by Pledgor to perform or observe any of the provisions
hereof.  All amounts payable by Pledgor under this Section 13 shall be due upon
demand and shall be part of the Secured Obligations.  Pledgor's obligations
under this Section 13 shall survive the termination of this Agreement and the
discharge of Pledgor's other obligations hereunder.

         SECTION XIV.  NO WAIVER; CUMULATIVE REMEDIES.  A.No failure on the
part of the Trustee to exercise, no course of dealing with respect to, and no
delay on the part of the Trustee in exercising, any right, power or remedy
hereunder shall operate as a waiver thereof; nor shall any single or partial
exercise of any such right, power or remedy hereunder preclude any other or
further exercise thereof or the exercise of any other right, power or remedy.
The remedies herein provided are cumulative and are not exclusive of any
remedies provided by law.

         (b)  In the event the Trustee shall have instituted any proceeding to
enforce any right, power or remedy under this Agreement by foreclosure, sale,
entry or otherwise, and such proceeding shall have been discontinued or
abandoned for any reason or shall have been determined adversely to the Trustee,
then and in every such case, Pledgor, the Trustee and each  holder of any of the
Secured Obligations shall be


                                     -12-




restored to their respective former positions and rights hereunder with respect
to the Pledged Collateral, and all rights, remedies and powers of the Trustee
and the Secured Parties shall continue as if no such proceeding had been
instituted.

         SECTION XV.  TRUSTEE.  The Trustee has been appointed as collateral
agent hereunder pursuant to the Indenture.  The Trustee shall take or refrain
from taking actions hereunder at the direction of the Holders in accordance with
the provisions of the Indenture.  The Trustee shall have the right hereunder to
make demands, to give notices, to exercise or refrain from exercising any
rights, and to take or refrain from taking action (including, without
limitation, the release or substitution of Pledged Collateral), in accordance
with this Agreement and the Indenture.  The Trustee may resign and a successor
Trustee may be appointed in the manner provided in the Indenture.  Upon the
acceptance of any appointment as Trustee by a successor Trustee, that successor
Trustee shall thereupon succeed to and become vested with all the rights,
powers, privileges and duties of the retiring Trustee under this Agreement, and
the retiring Trustee shall thereupon be discharged from its duties and
obligations under this Agreement; PROVIDED, HOWEVER, that the foregoing shall
not operate or be construed as a waiver of claims by Pledgor.  After any
retiring Trustee's resignation, the provisions of this Agreement shall inure to
its benefit as to any actions taken or omitted to be taken by it under this
Agreement while it was Trustee.

         SECTION XVI.  TRUSTEE MAY PERFORM; TRUSTEE APPOINTED ATTORNEY-IN-FACT.
If Pledgor shall fail to do any act or thing that it has covenanted to do
hereunder or if any warranty on the part of Pledgor contained herein shall be
breached, the Trustee or any Secured Party may (but shall not be obligated to)
do the same or cause it to be done or remedy any such breach, and may expend
funds for such purpose.  Any and all amounts so expended by the Trustee or such
Secured Party shall be paid by Pledgor promptly upon demand therefor, with
interest at the rate per annum equal to two (2) percent in excess of the rate
payable under the Notes during the period from and including the date on which
such funds were so expended to the date of repayment.  Pledgor's obligations
under this Section 16 shall survive the termination of this Agreement and the
discharge of Pledgor's other obligations under this Agreement.  Pledgor hereby
appoints the Trustee its attorney-in-fact with an interest, with full authority
in the place and stead of  Pledgor and in the name of Pledgor,

                                     -13-




or otherwise, from time to time in the Trustee's discretion to take any action
and to execute any instrument consistent with the terms of this Agreement and
the Indenture which the Trustee may deem necessary or advisable to assure,
perfect, convey, assign, transfer and confirm unto the Trustee the Lien on the
Pledged Collateral intended to be provided by this Agreement and which Pledgor
fails to do or execute and deliver within five (5) Business Days after Pledgor's
receipt of written notice to do or execute and deliver the same.  The foregoing
grant of authority is a power of attorney coupled with an interest and such
appointment shall be irrevocable for the term of this Agreement.

         SECTION XVII.  NOTICES.  Any notice or other communication herein
required or permitted to be given shall be given in the manner at the address
set forth in the Indenture, or as to any party at such other address as shall be
designated by such party in a written notice to the other party complying as to
delivery with the terms of this Section 17.

         SECTION XVIII.  CONTINUING SECURITY INTEREST; ASSIGNMENT.  This
Agreement shall create a continuing security interest in the Pledged Collateral
and shall (i) be binding upon Pledgor, its successors and assigns, and (ii)
inure, together with the rights and remedies of the Trustee hereunder, to the
benefit of the Trustee and the other Secured Parties and each of their
respective successors, transferees and assigns; no other Person (including,
without limitation, any other creditor of Pledgor) shall have any interest
herein or any right or benefit with respect hereto.  Without limiting the
generality of the foregoing clause (ii), any Secured Party may assign or
otherwise transfer any Note held by it secured by this Agreement to any other
Person in accordance with the terms of the Indenture, the Notes and relevant
federal and state securities laws, and such other Person shall thereupon become
vested with all the benefits in respect thereof granted to such Secured Party,
herein or otherwise, subject however, to the provisions of the Indenture.

         SECTION XIX.  GOVERNING LAW; TERMS.  THIS AGREEMENT SHALL BE GOVERNED
BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE
STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAWS, EXCEPT TO
THE EXTENT THAT THE VALIDITY OR PERFECTION OF THE SECURITY INTEREST HEREUNDER,
OR REMEDIES HEREUNDER, IN RESPECT OF ANY PARTICULAR  PROPERTY ARE GOVERNED BY
THE LAWS OF A JURISDICTION OTHER THAN THE STATE OF NEW YORK.

unenforceability without invalidating the remaining provisions hereof or
affecting the validity or enforceability of such provision in any other
jurisdiction.

amendments, waivers, consents or supplements hereto may be executed in any

         1.   any bankruptcy, insolvency, reorganization, arrangement,
    readjustment, composition, liquidation or the like of Pledgor;

         2.   any lack of validity or enforceability of the Indenture, the

    granted pursuant to the provisions of the Indenture; or

terms hereof, on the order of and at the sole cost and expense of Pledgor, and
such proper instruments and/or agreements (including UCC termination  statements
on Form UCC-3) as may be reasonably requested by Pledgor acknowledging the
