                              -------------------

        WHEREAS, pursuant to the Credit Agreement, the Lenders have severally
agreed to make, and have made, certain loans and other extensions of credit to
the Borrowers;

        WHEREAS, Holdings and the Borrowers have requested that certain
provisions of the Credit Agreement be amended pursuant to the Second Amendment,
dated as of February 15, 2001 (the "Amendment"), to the Credit Agreement;
                                    ---------

        WHEREAS, it is a condition precedent to the effectiveness of the
Amendment that the Guarantors shall have executed and delivered this Guarantee
to the Administrative Agent for the ratable benefit of the Lenders; and

        WHEREAS, the Guarantors are members of Holdings, and it is to the
advantage of the Guarantors that the Amendment become effective;

        NOW, THEREFORE, in consideration of the premises and to induce the
Administrative Agent and the Lenders to enter into the Amendment, the Guarantors
hereby agree with the Administrative Agent, for the ratable benefit of the
Lenders, as follows:

        1.  Defined Terms. (a) Unless otherwise defined herein, terms defined in
            -------------
the Credit Agreement andused herein shall have the meanings given to them in the
Credit Agreement.

        (b) The words "hereof," "herein" and "hereunder" and words of similar
import when used in this Guarantee shall refer to this Guarantee as a whole and
not to any particular provision of this Guarantee, and section and paragraph
references are to this Guarantee unless otherwise
<PAGE>

specified.

        (c) The meanings given to terms defined herein shall be equally
applicable to both the singular and plural forms of such terms.

        2.  Guarantee. (a) Subject to paragraphs (b) and (h) of this Section,
            ---------
each Guarantor hereby unconditionally and irrevocably guarantees to the
Administrative Agent, for the ratable benefit of the Lenders and their
respective successors, indorsees, transferees and assigns, the prompt and
complete payment by each of the Borrowers when due (whether at the stated
maturity or by acceleration) of the Obligations with respect to such Borrower.
This is a guarantee of payment; provided, that, except as provided in paragraph
                                --------
(c) of this Section, the Administrative Agent and the Lenders will not demand
payment of any Obligations hereunder until such Obligations have become due and
payable by the relevant Borrower and remain unpaid.

        (b) This Guarantee shall become effective as of the last day of any
fiscal quarter of Holdings ending on or after March 31, 2001 and on or before
March 31, 2002 if, and only if, the Consolidated Senior Leverage Ratio (for
purposes of this paragraph only, calculated by including the add-backs specified
in the second proviso of the definition of "Consolidated EBITDA" set forth in
the Credit Agreement) as at the last day of such fiscal quarter is greater than
3.00 to 1.00. If the Consolidated Senior Leverage Ratio as at the last day of
any such fiscal quarter is greater than 3.00 to 1.00, but less than or equal to
3.25 to 1.00, the total liability of the Guarantors hereunder shall not exceed
the principal sum of $8,000,000. If the Consolidated Senior Leverage Ratio as at
the last day of any such fiscal quarter is greater than 3.25 to 1.00, the total
liability of the Guarantors hereunder shall not exceed the principal sum of
$10,000,000. Each Guarantor agrees that the Obligations may at any time and from
time to time exceed the amount of the liability of such Guarantor hereunder
without impairing this Guarantee or affecting the rights and remedies of the
Administrative Agent or any Lender hereunder.

        (c) If the Guarantee becomes effective pursuant to paragraph (b) of this
Section and on or after the date of such effectiveness there occurs a Default
under any one or more of the covenants set forth in Sections 7.1(a), (b), (c) or
(e) of the Credit Agreement, then on the date which is the earlier of (x) the
date of delivery of the financial statements of Holdings and its Subsidiaries
and the Compliance Certificate for the fiscal quarter ending December 31, 2001
or (y) February 14, 2002, the Lenders shall have the right to demand the
Guarantors to pay to the Administrative Agent for the account of the Term Loan
Lenders an amount equal to the maximum total liability of the Guarantors then in
effect pursuant to paragraph (b) of this Section, to be applied as a ratable
prepayment of the Term Loans; provided, however, that if the Consolidated Senior
                              --------  -------
Leverage Ratio (excluding, for the avoidance of doubt, the add-backs specified
in the second proviso of the definition of "Consolidated EBITDA" set forth in
the Credit Agreement) as at December 31, 2001 is less than or equal to 2.00 to
1.00, then the Lenders shall have no such right to demand the Guarantors to make
such payment and the Guarantee shall thereupon terminate in accordance with
paragraph (h) of this Section.

        (d) Each Guarantor further agrees to pay any and all expenses
(including, without limitation, all fees and disbursements of counsel) which may
be paid or incurred by the Administrative Agent or any Lender in enforcing any
rights with respect to, or collecting against,
<PAGE>

such Guarantor under this Guarantee or obtaining advice of counsel in respect
thereof. Subject to paragraph (h) of this Section, this Guarantee shall remain
in full force and effect until the Obligations are paid in full and the
Commitments are terminated, notwithstanding that from time to time prior thereto
either Borrower may be free from any Obligations.

        (e) No payment or payments made by either Borrower or any other Person
or received or collected by the Administrative Agent or any Lender from either
Borrower or any other Person by virtue of any action or proceeding or any
set-off or appropriation or application, at any time or from time to time, in
reduction of or in payment of the Obligations shall be deemed to modify, reduce,
release or otherwise affect the liability of the Guarantors hereunder which
shall, notwithstanding any such payment or payments (other than payments made by
either Guarantor in respect of the Obligations or payments received or collected
from either Guarantor in respect of the Obligations), remain liable for the
Obligations until the Obligations are paid in full and the Commitments are
terminated, subject to the provisions of paragraph (h) of this Section.

        (f) Each Guarantor agrees that whenever, at any time, or from time to
time, it shall make any payment to the Administrative Agent or any Lender on
account of its liability hereunder, it will notify the Administrative Agent and
such Lender in writing that such payment is made under this Guarantee for such
purpose.

        (g) The obligation of each Guarantor hereunder is limited to 50% of the
total obligations of the Guarantors hereunder.

        (h) If as of the last day of any fiscal quarter of Holdings the
Consolidated Senior Leverage Ratio (excluding, for the avoidance of doubt, the
add-backs specified in the second proviso of the definition of "Consolidated
EBITDA" set forth in the Credit Agreement) is less than or equal to 2.00 to
1.00, this Guarantee, and all obligations of the Guarantors hereunder, shall
terminate as of such date. In addition, if the Guarantee does not become
effective at any time pursuant to paragraph (b) of this Section, all obligations
of the Guarantors hereunder shall terminate as of March 31, 2002.

        3.  Right of Set-off. The Administrative Agent and each Lender is hereby
            ----------------
irrevocably authorized at any time and from time to time without notice to
either Guarantor, any such notice being expressly waived by each Guarantor, to
set off and appropriate and apply any and all deposits (general or special, time
or demand, provisional or final), in any currency, and any other credits,
indebtedness or claims, in any currency, in each case whether direct or
indirect, absolute or contingent, matured or unmatured, at any time held or
owing by the Administrative Agent or such Lender to or for the credit or the
account of the Guarantors, or any part thereof in such amounts as the
Administrative Agent or such Lender may elect, against or on account of the
obligations and liabilities of the Guarantors to the Administrative Agent or
such Lender hereunder becoming due and payable. The Administrative Agent and
each Lender shall notify the Guarantors promptly of any such set-off and the
application made by the Administrative Agent or such Lender, as the case may be,
of the proceeds thereof; provided that the failure to give such notice shall not
affect the validity of such set-off and application. The rights of the
Administrative Agent and each Lender under this paragraph are in addition to
other rights and remedies (including, without limitation, other rights of
set-off) which the Administrative Agent or such Lender may have.
<PAGE>

        4.  No Subrogation. Notwithstanding any payment or payments made by
            --------------
either Guarantor hereunder (including, without limitation, any payment pursuant
to paragraph (c) of Section 2 hereof), or any set-off or application of funds of
either Guarantor by the Administrative Agent or any Lender, neither Guarantor
shall be entitled to be subrogated to any of the rights of the Administrative
Agent or any Lender against either of the Borrowers or against any collateral
security or guarantee or right of offset held by the Administrative Agent or any
Lender for the payment of the Obligations, nor shall either Guarantor seek or be
entitled to seek any contribution or reimbursement from either of the Borrowers
in respect of payments made by such Guarantor hereunder (other than the payment
of certain guarantee fees previously disclosed to the Administrative Agent and
the Lenders), until all amounts owing to the Administrative Agent and the
Lenders by the Borrowers on account of the Obligations are paid in full and the
Commitments are terminated. If any amount shall be paid to either Guarantor on
account of such subrogation rights at any time when all of the Obligations shall
not have been paid in full, such amount shall be held by such Guarantor in trust
for the Administrative Agent and the Lenders, segregated from other funds of
such Guarantor, and shall, forthwith upon receipt by the Guarantor, be turned
over to the Administrative Agent in the exact form received by such Guarantor
(duly indorsed by such Guarantor to the Administrative Agent, if required), to
be applied against the Obligations, whether matured or unmatured, in such order
as the Administrative Agent and the Lenders may determine.

        5.  Amendments, etc. with respect to the Obligations; Waiver of Rights.
            ------------------------------------------------------------------
Each Guarantor shall remain obligated hereunder notwithstanding that, without
any reservation of rights against such Guarantor, and without notice to or
further assent by such Guarantor, any demand for payment of any of the
Obligations made by the Administrative Agent or any Lender may be rescinded by
the Administrative Agent or such Lender, and any of the Obligations continued,
and the Obligations, or the liability of any other party upon or for any part
thereof, or any collateral security or guarantee therefor or right of offset
with respect thereto, may, from time to time, in whole or in part, be renewed,
extended, amended, modified, accelerated, compromised, waived, surrendered or
released by the Administrative Agent or any Lender, and the Credit Agreement,
any Notes, and the other Loan Documents and any other documents executed and
delivered in connection therewith may be amended, modified, supplemented or
terminated, in whole or in part, as the Administrative Agent (or the Required
Lenders, as the case may be) may deem advisable from time to time, and any
collateral security, guarantee or right of offset at any time held by the
Administrative Agent or any Lender for the payment of the Obligations may be
sold, exchanged, waived, surrendered or released. Neither the Administrative
Agent nor any Lender shall have any obligation to protect, secure, perfect or
insure any Lien at any time held by it as security for the Obligations or for
this Guarantee or any property subject thereto. When making any demand hereunder
against either Guarantor, the Administrative Agent or any Lender may, but shall
be under no obligation to, make a similar demand on either of the Borrowers or
any other guarantor, and any failure by the Administrative Agent or any Lender
to make any such demand or to collect any payments from either of the Borrowers
or any such other guarantor or any release of either of the Borrowers or such
other guarantor shall not relieve such Guarantor of its obligations or
liabilities hereunder, and shall not impair or affect the rights and remedies,
express or implied, or as a matter of law, of the Administrative Agent or any
Lender against such Guarantor. For the purposes hereof "demand" shall include
the commencement and continuance of any legal proceedings.
<PAGE>

        6.  Guarantee Absolute. Each Guarantor waives any and all notice of the
            ------------------
creation, renewal, extension or accrual of any of the Obligations and notice of
or proof of reliance by the Administrative Agent or any Lender upon this
Guarantee or acceptance of this Guarantee; the Obligations, and any of them,
shall conclusively be deemed to have been created, contracted or incurred, or
renewed, extended, amended or waived, in reliance upon this Guarantee; and all
dealings between the Borrowers and either Guarantor, on the one hand, and the
Administrative Agent and the Lenders, on the other, shall likewise be
conclusively presumed to have been had or consummated in reliance upon this
Guarantee. Each Guarantor waives diligence, presentment, protest, demand for
payment and notice of default or nonpayment to or upon the Borrowers or such
Guarantor with respect to the Obligations. This Guarantee shall be construed as
a continuing and absolute guarantee of payment without regard to (a) the
validity, regularity or enforceability of the Credit Agreement, any Note, or any
other Loan Document, any of the Obligations or any other collateral security
therefor or guarantee or right of offset with respect thereto at any time or
from time to time held by the Administrative Agent or any Lender, (b) any
defense, set-off or counterclaim (other than a defense of payment or
performance) which may at any time be available to or be asserted by either
Borrower against the Administrative Agent or any Lender, or (c) any other
circumstance whatsoever (with or without notice to or knowledge of either
Borrower or either Guarantor) which constitutes, or might be construed to
constitute, an equitable or legal discharge of either Borrower for the
Obligations, or of either Guarantor under this Guarantee, in bankruptcy or in
any other instance. When pursuing its rights and remedies hereunder against
either Guarantor, the Administrative Agent and any Lender may, but shall be
under no obligation to, pursue such rights and remedies as it may have against
either Borrower or any other Person or against any collateral security or
guarantee for the Obligations or any right of offset with respect thereto, and
any failure by the Administrative Agent or any Lender to pursue such other
rights or remedies or to collect any payments from either Borrower or any such
other Person or to realize upon any such collateral security or guarantee or to
exercise any such right of offset, or any release of either Borrower or any such
other Person or of any such collateral security, guarantee or right of offset,
shall not relieve such Guarantor of any liability hereunder, and shall not
impair or affect the rights and remedies, whether express, implied or available
as a matter of law, of the Administrative Agent or any Lender against such
Guarantor. Subject to paragraph (h) of Section 2 hereof, this Guarantee shall
remain in full force and effect and be binding in accordance with and to the
extent of its terms upon each Guarantor and its successors and assigns thereof,
and shall inure to the benefit of the Administrative Agent and the Lenders, and
their respective successors, indorsees, transferees and assigns, until all the
Obligations and the obligations of each Guarantor under this Guarantee shall
have been satisfied by payment in full and the Commitments shall be terminated,
notwithstanding that from time to time during the term of the Credit Agreement
the Borrowers may be free from any Obligations.

        7.  Reinstatement. This Guarantee shall continue to be effective, or be
            -------------
reinstated, as the case may be, if at any time payment, or any part thereof, of
any of the Obligations made while this Guarantee is effective is thereafter
rescinded or must otherwise be restored or returned by the Administrative Agent
or any Lender upon the insolvency, bankruptcy, dissolution, liquidation or
reorganization of either Borrower or upon or as a result of the appointment of a
receiver, intervenor or conservator of, or trustee or similar officer for,
either Borrower or any substantial part of its property, or otherwise, all as
though such payments had not been made.

        8.  Payments. Each Guarantor hereby agrees that the Obligations will be
            --------
paid to the
<PAGE>

Administrative Agent without set-off or counterclaim in U.S. Dollars at the
office of the Administrative Agent located at 100 Federal Street, Boston,
Massachusetts 02110.

        9.  Representations and Warranties. Each Guarantor represents and
            ------------------------------
warrants to the Administrative Agent and the Lenders that:

        (a) the Guarantor is a limited liability company duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
incorporation and has the corporate power and authority and the legal right to
own and operate its property, to lease the property it operates and to conduct
the business in which it is currently engaged;

        (b) the Guarantor has the corporate power and authority and the legal
right to execute and deliver, and to perform its obligations under, this
Guarantee, and has taken all necessary corporate action to authorize its

jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

Guarantee may be waived by the Administrative Agent and the Lenders in a letter

transmission from the Administrative Agent.

indulgence, omission or otherwise be deemed to have waived any right or remedy

breach of any of the terms and conditions hereof. No failure to exercise, nor
any delay in exercising, on the part of the Administrative Agent or any Lender,
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 the Administrative Agent or any Lender of
any right or remedy hereunder on any one occasion shall not be construed as a
bar to any right or remedy which the Administrative Agent or such Lender would
otherwise have on any future occasion.

        (c) The rights and remedies herein provided are cumulative, may be
exercised singly or concurrently and are not exclusive of any other rights or

           AMENDED SECTION 12 OF THE 1994 MANAGEMENT STOCK OPTION PLAN

     12.  (a)  NON-TRANSFERABILITY  OF  OPTIONS.  Options  and all other  rights
thereunder shall be  non-transferrable  or  non-assignable by the holder thereof
except to the extent  that the  estate of a deceased  holder of an Option may be
permitted to exercise them.  Options may be exercised or surrendered  during the
holder's lifetime only by the holder thereof.

          (b)  Notwithstanding   the   foregoing,   the  Committee  may  in  the
applicable  option  certificate  or at any  time  after  the date of grant by an
instrument  amending terms provided for in the option  certificate  provide that
Options may be transferred by a holder  without  consideration,  subject to such
rules as the Committee  may adopt  consistent  with the terms of the  applicable
option certificate to preserve the purposes of the Plan, to:

               (A)  any person who is a "family  member" of the holder,  as such
                    term is used in the instructions to Form S-8  (collectively,
                    the "Immediate Family Members");

               (B)  a trust  solely for the benefit of the holder and his or her
                    Immediate Family Members;

               (C)  a  partnership  or  limited  liability  company  whose  only
                    partners  or  shareholders  are  the  holder  and his or her
                    Immediate Family Members; or

               (D)  any other  transferee  as may be approved  either (a) by the
                    Board of Directors or the Committee in its sole  discretion,
                    or (b) as  provided  in the terms of the  applicable  option
                    certificate;

(each transferee described in clauses (A), (B), (C) and (D) above is hereinafter
referred to as a  "Permitted  Transferee");  PROVIDED  that the holder gives the
Committee  advance  written  notice  describing  the terms and conditions of the
proposed  transfer and the Committee  notifies the holder in writing that such a
transfer  would  comply with the  requirements  of the Plan and the terms of any
applicable option certificate.

          (c)  The  terms  of any  Option  transferred  in  accordance  with the
immediately  preceding sentence shall apply to the Permitted  Transferee and any
reference in the Plan or in an option certificate to a holder shall be deemed to
refer to the Permitted  Transferee,  except that (a) Permitted Transferees shall
not be  entitled  to  transfer  any  Options,  other than by will or the laws of
descent and  distribution;  (b) Permitted  Transferees  shall not be entitled to
exercise any transferred  Options unless there shall be in effect a registration
statement on an appropriate form covering the shares to be acquired  pursuant to
the exercise of such Option if the  Committee  determines,  consistent  with the
terms of any applicable option certificate,  that such a registration  statement
is  necessary or  appropriate,  (c) the  Committee  or the Company  shall not be
required to provide any notice to a  Permitted  Transferee,  whether or not such
notice is or would  otherwise have been required to be given to the holder under
the Plan or otherwise,  and (d) the  consequences of termination of the holder's
employment  by, or services to, the Company or a  Subsidiary  under the terms of
the Plan and the applicable option certificate shall continue to be applied with
respect to the holder,  following  which the Options shall be exercisable by the
Permitted  Transferee only to the extent, and for the periods,  specified in the
Plan and the terms of the applicable option certificate.
