        NOW, THEREFORE, the Guarantor hereby agrees with the Agent and each of
the Obligees as follows:

        1. Definitions. Agent. "Agent" shall have the meaning set forth in the
first paragraph hereof and shall also include any entity that may be appointed
as successor to Fleet National Bank in its capacity as Agent hereunder (if it
shall no longer be willing to act in such capacity) by the holders of a majority
in principal amount of the then outstanding Obligations.

        Event of Default. Any Event of Default as defined in and under the
Credit Agreement, the 1995 Agreement, the Nova Agreement or the 2000 Agreement.

        Obligations. The "Obligations" shall mean the aggregate of each of the
"Obligations" as defined in the Credit Agreement, and all obligations under the
1995 Agreement, the Nova Agreement and the 2000 Agreement including, without
limitation, principal, interest, Makewhole Price (as defined in the Note
Agreements) and all other amounts owing by the Company and Nova under the Note
Agreements and the Notes.

        Permitted Investments. "Permitted Investments" means investments in the
following:

        (a) Investments in United States Governmental Securities provided that
such obligations mature within 365 days from the date of acquisition thereof.
"United States Governmental Securities" means any direct obligation of, or
obligation guaranteed by, the United States of America, or any agency controlled
or supervised by or acting as an instrumentality of the United States of America
pursuant to authority granted by the Congress of the United States of America,
so long as such obligation or guarantee shall have the benefit of the full faith
and credit of the United States of America which shall have been pledged
pursuant to authority granted by the Congress of the United States of America;

        (b) Investments in certificates of deposit or banker's acceptances

not less than "A 1" if rated by S&P."

        2. Guaranty of Payment and Performance. The Guarantor hereby guarantees
to each of the Obligees, the full and punctual payment when due (whether at
stated maturity, by required pre-payment, by acceleration or otherwise), as well
as the performance, of all of the Obligations including all such which would
become due but for the operation of the automatic stay pursuant to Section
362(a) of the Federal Bankruptcy Code and the operation of Sections 502(b) and
506(b) of the Federal Bankruptcy Code. This Guaranty is an absolute,
unconditional and continuing guaranty of the full and punctual payment and
performance of all of the Obligations and not of their collectibility only and
is in no way conditioned upon any requirement that the Agent or any Obligee
first attempt to collect any of the Obligations from the Company or resort to
any collateral security or other means of obtaining payment. Should the Company
default in the payment or performance of any of the Obligations, the obligations
of the Guarantor hereunder with respect to such Obligations in default shall,
upon demand by the Agent, or any Noteholder, become immediately due and payable
to the Agent, for the benefit of the Obligees and the Agent, without demand or
notice of any nature, all of which are expressly waived by the Guarantor.
Payments by the Guarantor hereunder may be required by the Agent or the Obligees
on any number of occasions. All payments by the Guarantor to any Obligee at any
time after an Event of Default has occurred and is continuing shall be turned
over to the Agent for distribution in accordance with the terms hereof. All
payments by the Guarantor hereunder shall be made to the Agent, in the manner
and at the place of payment specified therefor in the Credit Agreement for the
account of the Obligees and the Agent. The Obligees will share all payments
received hereunder on a pro rata basis with respect to their individual
Obligations, regardless of whether this Guaranty is found to be inapplicable to
some or all of any Obligee's respective Obligations.

        3. Guarantor's Agreement to Pay Enforcement Costs, etc. The Guarantor
further agrees, as the principal obligor and not as a guarantor only, to pay to
the Agent and each of the Obligees, on demand, all costs and expenses (including
court costs and legal expenses) incurred or expended by the Agent or any Obligee
in connection with the Obligations, this Guaranty and the enforcement thereof
(which enforcement may be undertaken by any Obligee, so long as the proceeds of
such enforcement are paid to the Agent by such Obligee, for distribution in
accordance with the terms hereof), together with interest on amounts recoverable
under this Section 3 from the time when such amounts become due until payment,
whether before or after judgment, at the rate of interest for overdue principal
set forth in the Credit Agreement, the 1995 Agreement, the Nova Agreement or the
2000 Agreement, as applicable, provided that if such interest exceeds

<PAGE>

                                       -4-

the maximum amount permitted to be paid under applicable law, then such interest
shall be reduced to such maximum permitted amount.

        4. Proceeds Received Under the Guaranty.

                4.1 Guaranty Account.

                (a) The Agent shall establish and maintain an account into
which, subject to Section 4.1(b), it shall deposit all amounts received by it in
its capacity as Agent for the benefit of the Obligees (and not in any other
capacity), in respect of this Guaranty so long as an Event of Default shall be
continuing, including all monies received on account of any payment on demand or
other realization pursuant to this Guaranty (the "Guaranty Account"). All
amounts deposited in the Guaranty Account shall be held by the Agent for the
benefit of the Obligees subject to the terms hereof, it being understood that
any such amounts may be released to the Guarantor to the extent required by this
Guaranty. The Guarantor shall have no rights with respect to, and the Agent, for
the benefit of the Obligees shall have exclusive dominion and control over, the
Guaranty Account.

                (b) The Agent shall establish sub-accounts in its Guaranty
Account with respect to each outstanding Letter of Credit (as defined in the
Credit Agreement). All amounts deposited in the Guaranty Account in respect of
Letters of Credit shall be allocated among, and deposited in, the respective
sub-accounts therein pro rata in accordance with the Reimbursement Obligations
(as defined in the Credit Agreement) with respect to the related Letters of
Credit. If, on or after the date on which any funds are deposited in the
Guaranty Account pursuant to paragraph (b) above, any Letter of Credit is drawn
upon by the beneficiary thereof, the Agent shall apply any funds in the
sub-account with respect to such Letter of Credit to the reimbursement of such
Letter of Credit Participation (as defined in the Credit Agreement) as if such
reimbursement were being made by the Company pursuant to the Credit Agreement
(but not in an amount in excess of the amount of such drawing plus accrued and
unpaid interest thereon from the date of draw to the date of payment).

                (c) At the time of any expiration or cancellation of any
outstanding Letter of Credit, or any other reduction in the amount of
Reimbursement Obligations thereunder (other than as a result of a Letter of
Credit Participation), the amount of funds in the sub-account with respect to
such Letter of Credit (or, in the case of any partial reduction in the amount of
Reimbursement Obligations thereunder, a pro rata portion of such funds) shall be
released from such sub-account, and the funds so released shall be deposited in
the Guaranty Account.

                4.2 Application of Proceeds.

                (a) Amounts deposited in the Guaranty Account shall be applied
in the following order of priority:

<PAGE>

                                       -5-

                First, to the payment of (i) the reasonable costs and expenses
(including attorney fees and disbursements) incurred by the Agent in
administering and carrying out its obligations under this Guaranty and (ii) all
amounts owing to the Agent in respect of indemnification or expense
reimbursement claims owing to the Agent pursuant to Section 5;

                Second, to the payment of (i) the reasonable costs and expenses
(including attorney fees and disbursements) of any Obligee in exercising or
attempting to exercise any right or remedy hereunder and (ii) all amounts owing
to any Obligee in respect of indemnification or expense reimbursement claims
owing to it pursuant to Section 5;

                Third, to the Obligees in respect of the outstanding Obligations
of each Obligee, respectively, at such time, pro rata in accordance with the
aggregate amounts of the outstanding Obligations of each Obligee, respectively,
at such time, until the outstanding Obligations shall have been paid in full;
and

                Fourth, the balance, if any, to the Guarantor or such other
person or persons as shall be entitled thereto.

                (b) All amounts deposited in any sub-account in the Guaranty
Account shall be applied as provided in Sections 4.1 (b) and (c).

                (c) Each Obligee agrees that, notwithstanding any provision of
this Guaranty, the Credit Agreement, the 1995 Agreement, the Nova Agreement or
the 2000 Agreement, any sums and amounts received by such Obligee pursuant to
this Section 4.2 shall be applied to the payment of its outstanding Obligations
as follows: first, to the payment of all outstanding Obligations owed to such
Obligee, other than principal, premium, interest and obligations in respect of
reimbursement of Letter of Credit Participations; second, to the payment of all
outstanding Obligations owed to such Obligee consisting of accrued interest; and
third, to the payment of all outstanding Obligations owed to such Obligee
consisting of principal, premium, Makewhole Price and obligations in respect of
reimbursement of Letter of Credit Participations.

                4.3. Time of Payments. Unless the Agent shall have received
written instructions from the holders of a majority in principal amount of the
Obligations as to the times at which any amounts are to be distributed pursuant
to Section 4.2, all distributions under Section 4.2 shall be made at such times
and as promptly as the Agent shall determine to be reasonable and practicable
under the circumstances, subject to Section 4.4; provided, however, that any
distributions from the Guaranty Account shall be made substantially
simultaneously; provided, further, that distributions from the Guaranty Account
shall be made at least once in each 6 months or any time the amount on deposit
therein exceeds $1,000,000.

                4.4. Application of Amounts Not Distributable. If there is no
provision under the Credit Agreement, the 1995 Agreement, the Nova Agreement or
the 2000

<PAGE>

                                       -6-

Agreement, as the case may be, for the application of amounts that are
to be distributed to the Lenders or the Noteholders pursuant to Section 4.2
(whether by virtue of the applicable outstanding Obligations thereunder not
being then due and payable or otherwise) or for the holding of such amounts by
or on behalf of such parties pending application thereof, then the Agent, for
the benefit of the Obligees shall invest the amounts in the Guaranty Account in
investments permitted by Section 4.5 and shall hold such amounts and all
proceeds of such investments in the Guaranty Account for the benefit of the
Obligees until such amounts are either applied against the outstanding
Obligations of each Obligee, respectively, or such outstanding Obligations have
been paid in full.

                4.5. Investment of Amounts in Guaranty Account. Pending the
disbursement thereof pursuant to the terms of this Guaranty, all amounts in the
Guaranty Account shall (to the extent deemed practical) be invested by the
Agent, for the benefit of the Obligees, in Permitted Investments. The Agent
shall, to the extent that the timing of distributions to be made from the
Guaranty Account is known or can be reasonably anticipated, select Permitted
Investments for the Guaranty Account that mature prior to the anticipated date
of any distribution to be made from the Guaranty Account. The Agent shall not be
liable for any loss resulting from any investment made in accordance with the
provisions of this Section 4.5, except to the extent such loss was the result of
such person's gross negligence or willful misconduct. The Agent agrees to
account to the Obligees for each investment of funds in the Guaranty Account,
and to supply to the Obligees the documents relating thereto, promptly upon
request.

                4.6. Information. Each Obligee agrees promptly from time to
time, upon written request of the Agent, to advise the Agent of the nature and
amount of outstanding obligations owing to it as of such date as the Agent may
specify.

        5. Expenses and Indemnification by the Guarantor. By countersigning this
Guaranty, the Guarantor agrees (i) to reimburse the Agent and each Obligee, on
demand, for any reasonable expenses incurred, including reasonable (1) counsel
fees, (2) other charges and (3) disbursements and compensation of agents,
arising out of, in any way connected with, or as a result of, the execution or
delivery of this Guaranty or any agreement or instrument contemplated hereby or
thereby or the performance by the parties hereto or thereto of their respective
obligations hereunder or thereunder or in connection with the enforcement or
protection of the rights of the Agent, and the Obligees under this Guaranty and
(ii) to indemnify and hold harmless the Agent, the Obligees and each of their
respective directors, officers, employees and agents (each such person being
called an "Indemnitee"), on demand, from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever which may be imposed
on, incurred by or asserted against any Indemnitee in their respective
capacities or any of them in any way relating to or arising out of this Guaranty
or any action taken or omitted by them under this Guaranty; provided, however,
that the Guarantor shall not be liable to any Indemnitee for any such
liabilities, obligations, losses, damages,

<PAGE>

                                       -7-

penalties, actions, judgments, suits, costs, expenses or disbursements to the
extent they have resulted from the gross negligence or willful misconduct of
such Indemnitee.

        6. Waivers by Guarantor; Lender's Freedom to Act. The Guarantor agrees
that the Obligations will be paid and performed strictly in accordance with
their respective terms, regardless of any law, regulation or order now or
hereafter in effect in any jurisdiction affecting any of such terms or the
rights of the Agent or any Obligee with respect thereto. The Guarantor waives
promptness, diligences, presentment, demand, protest, notice of acceptance,
notice of any Obligations incurred and all other notices of any kind, all
defenses which may be available by virtue of any valuation, stay, moratorium law
or other similar law now or hereafter in effect, any right to require the
marshalling of assets of the Company or any other entity or other person
primarily or secondarily liable with respect to any of the Obligations, and all
suretyship defenses generally. Without limiting the generality of the foregoing,
the Guarantor agrees to the provisions of any instrument evidencing, securing or
otherwise executed in connection with any Obligation and agrees that the
obligations of the Guarantor hereunder shall not be released or discharged, in
whole or in part, or otherwise affected by (i) the failure of the Agent or any
Obligee to assert any claim or demand or to enforce any right or remedy against
the Company or any other entity or other person primarily or secondarily liable
with respect to any of the Obligations; (ii) any extensions, compromise,
refinancing, consolidation or renewals of any Obligation; (iii) any change in
the time, place or manner of payment of any of the Obligations or any
rescissions, waivers, compromise, refinancing, consolidation or other amendments
or modifications of any of the terms or provisions of the Obligations or any
other agreement evidencing, securing or otherwise executed in connection with
any of the Obligations, (iv) the addition, substitution or release of any entity
or other person primarily or secondarily liable for any Obligation; (v) the
adequacy of any rights which the Agent or any Obligee may have against any
collateral security or other means of obtaining repayment of any of the
Obligations; (vi) the impairment of any collateral securing any of the
Obligations, including without limitation the failure to perfect or preserve any
rights which the Agent or any Obligee might have in such collateral security or
the substitution, exchange, surrender, release, loss or destruction of any such
collateral security; or (vii) any other act or omission which might in any
manner or to any extent vary the risk of the Guarantor or otherwise operate as a
release or discharge of the Guarantor, all of which may be done without notice
to the Guarantor. To the fullest extent permitted by law, the Guarantor hereby
expressly waives any and all rights or defenses arising by reason of (A) any
"one action" or "anti-deficiency" law which would otherwise prevent the Agent or
any Obligee from bringing any action, including any claim for a deficiency, or
exercising any other right or remedy (including any right of set-off), against
the Guarantor before or after the Agent's or such Obligee's commencement or
completion of any foreclosure action, whether judicially, by exercise of power
of sale or otherwise, or (B) any other law which in any other way would
otherwise require any election of remedies by the Agent or any Obligee.

<PAGE>

                                       -8-

         7. Unenforceability of Obligations Against Company. If for any reason
the Company has no legal existence or is under no legal obligation to discharge
any of the Obligations, or if any of the Obligations have become irrecoverable
from the Company by reason of the Company's insolvency, bankruptcy or
reorganization or by other operation of law or for any other reason, this
Guaranty shall nevertheless be binding on the Guarantor to the same extent as if
the Guarantor at all times had been the principal obligor on all such
Obligations. In the event that acceleration of the time for payment of any of
the Obligations is stayed upon the insolvency, bankruptcy or reorganization of
the Company, or for any other reason, all such amounts otherwise subject to
acceleration under the terms of any of the Obligations or any other agreement
evidencing, securing or otherwise executed in connection with any Obligation
shall be immediately due and payable by the Guarantor.

        8. Subrogation; Subordination.

                8.1. Waiver of Rights Against Company. Until the final payment
        and performance in full of all of the Obligations, the Guarantor shall
        not exercise and hereby waives any rights against the Company arising as
        a result of payment by the Guarantor hereunder, by way of subrogation,
        reimbursement, restitution, contribution or otherwise, and will not
        prove any claim in competition with the Agent or any Obligee in respect
        of any payment hereunder in any bankruptcy, insolvency or reorganization
        case or proceedings of any nature; the Guarantor will not claim any
        setoff, recoupment or counterclaim against the Company in respect of any
        liability of the Guarantor to the Company; and the Guarantor waives any
        benefit of and any right to participate in any collateral security which
        may be held by the Agent or any Obligee.

                8.2. Subordination. The payment of any amounts due with respect
        to any indebtedness of the Company for money borrowed or credit received
        now or hereafter owed to the Guarantor is hereby subordinated to the
        prior payment in full of all of the Obligations. The Guarantor agrees
        that, after the occurrence of any default in the payment or performance
        of any of the Obligations, the Guarantor will not demand, sue for or
        otherwise attempt to collect any such indebtedness of the Company to the
        Guarantor until all of the Obligations shall have been paid in full. If,
        notwithstanding the foregoing sentence, the Guarantor shall collect,
        enforce or receive any amounts in respect of such indebtedness while any
        Obligations are still outstanding, such amounts shall be collected,
        enforced and received by the Guarantor as trustee for the Obligees and
        the Agent and be paid over to the Agent, for each of the Obligees and
        the Agent, on account of the Obligations without affecting in any manner
        the liability of the Guarantor under the other provisions of this
        Guaranty.

                8.3. Provisions Supplemental. The provisions of this Section 8
        shall be supplemental to and not in derogation of any rights and
        remedies of the Obligees and the Agent under any separate subordination
        agreement which the Agent or any of the Obligees may at any time and
        from time to time enter into with the Guarantor for the benefit of the
        Obligees and the Agent.

<PAGE>

                                       -9-

        9. Setoff. Regardless of the adequacy of any collateral security or
other means of obtaining payment of any of the Obligations, each of the Agent
and the Obligees is hereby authorized at any time and from time to time, without
notice to the Guarantor (any such notice being expressly waived by the
Guarantor) and to the fullest extent permitted by law, to set off and apply such
deposits and other sums against the obligations of the Guarantor under this
Guaranty, whether or not the Agent or such Obligee shall have made any demand
under this Guaranty and although such obligations may be contingent or
unmatured. Any funds obtained by any such setoff shall be paid to the Agent for
deposit into the Guaranty Account.

        10. Further Assurances. The Guarantor agrees that it will from time to
time, at the request of the Agent or any Obligee, do all such things and execute
all such documents as the Agent or such Obligee may consider necessary or
desirable to give full effect to this Guaranty and to perfect and preserve the
rights and powers of the Obligees and the Agent hereunder. The Guarantor
acknowledges and confirms that the Guarantor itself has established its own
adequate means of obtaining from the Company on a continuing basis all
information desired by the Guarantor concerning the financial condition of the
Company and that the Guarantor will look to the Company and not to the Agent or
any Obligee in order for the Guarantor to keep adequately informed of changes in
the Company's financial condition.

        11. Termination; Reinstatement. This Guaranty shall remain in full force
and effect until the Agent and the Obligees are given written notice of the
Guarantor's intention to discontinue this Guaranty, notwithstanding any
intermediate or temporary payment or settlement of the whole or any part of the
Obligations. No such notice shall be effective unless received and acknowledged
by an officer of the Agent and an officer of each Noteholder, at the address of
the Agent for notices set forth in Section 16.6 of the Credit Agreement and at
the address of each Noteholder specified in or pursuant to the Note Agreements.
No such notice shall affect any rights of the Agent or any Obligee hereunder,
including without limitation the rights set forth in Sections 5 and 8, with
respect to any Obligations incurred or accrued prior to the receipt of such
notice or any Obligations incurred or accrued pursuant to any contract or
commitment in existence prior to such receipt, and this Guaranty shall remain in
full force and effect until all such Obligations are paid in full. This Guaranty
shall continue to be effective or be reinstated, notwithstanding any such
notice, if at any time any payment made or value received with respect to any
Obligation is rescinded or must otherwise be returned by the Agent or any
Obligee upon the insolvency, bankruptcy or reorganization of the Company, or
otherwise, all as though such payment had not been made or value received.

        12. Invalidated Payments. If the Agent or any Obligee receives any
amount which is shared pursuant to this Guaranty that is subsequently required
to be returned or repaid by the Agent or Obligee to the Guarantor, the Company
or any affiliate thereof or their respective representatives or successors in
interest, whether by court order, settlement or otherwise (a "Repayment Event"),
then

                (a)     if the Repayment Event results in the Agent being
required to return or repay any amount distributed by it to the Obligees under
this Guaranty, each

<PAGE>

                                      -10-

Obligee to which such amount was distributed shall, forthwith upon its receipt
of a notice thereof from the Agent, pay the Agent an amount equal to its ratable
share (based on the amount distributed to such Obligee) of the amount required
to be returned or repaid relating to such Repayment Event,

                (b)     if the Repayment Event results in any Obligee (any such
Obligee, an "Affected Obligee") being required to return or repay any amount
received by it which was delivered to and distributed by the Agent to the
Affected Obligee and the other Obligees pursuant to this Guaranty, each other
Obligee to which any amount was distributed shall, forthwith upon its receipt of
notice thereof from the Affected Obligee, pay the Agent an amount, up to an
amount equal to the prior distributions to such other Obligee, for distribution
to such Affected Obligee such that, after giving effect to such payment and
distribution, all Obligees shall have received such proportion of the amounts
distributed pursuant to this Guaranty as they would have received had the
original payment which was the subject of the Repayment Event not occurred, and

                (c)     in either case, the Agent shall thereafter apply all
amounts to be distributed pursuant hereto in a manner consistent with the terms
of this Guaranty such that all Obligees receive such proportion of such amounts
as they would have received had the original payment which is required to be
returned or repaid as the result of a Repayment Event not occurred;

it being understood that if any Obligee shall fail to promptly pay any such
amount to the Agent, (i) the Agent may deduct such amount from any amount
payable thereafter to such Obligee under this Guaranty, and (ii) such amount not
paid to the Agent within thirty (30) days of receipt of such notice from the
Agent, shall bear interest from the expiry of such thirty (30) day period at a
rate per annum equal to the Base Rate (as defined in the Credit Agreement) from
time to time and shall be due and owing by such Obligee.

        13. Successors and Assigns. This Guaranty shall be binding upon the
Guarantor, its successors and assigns, and shall inure to the benefit of the
Agent and the Obligees and their respective successors, transferees and assigns.
Without limiting the generality of the foregoing sentence, each Obligee (as
applicable) may assign or otherwise transfer the Credit Agreement, the Notes,
the other Loan Documents, the 1995 Agreement, the Nova Agreement, the 2000
Agreement or any other agreement or note held by it evidencing, securing or
otherwise executed in connection with the Obligations, or sell participations in
any interest therein, to any other entity or other person, and such other entity
or other person shall thereupon become vested, to the extent set forth in the
agreement evidencing such assignment, transfer or participation, with all the
rights in respect thereof granted to such Obligee herein, all in accordance with
Section 15 of the Credit Agreement, Section 11.4 of the 1995 Agreement, Section
11.4 of the Nova Agreement and Section 11.4 of the 2000 Agreement. The Guarantor

Nova Agreement and Section 7.4 of the 2000 Agreement, provided that no Event of
Default exists and is continuing.

        14. Joinder Agreement and Affirmation. To the extent requested by the
Agent for the benefit of the Obligees, or by any Obligee, the Guarantor will
cause each Subsidiary (excluding any foreign Subsidiaries) assigned any of the
Guarantor's Obligations in accordance with Section 13, to execute and deliver to
the Agent for the benefit of the Obligees, (a) a Joinder Agreement and
Affirmation in the form of Exhibit A attached hereto, and (b) any other
instruments and documents as the Agent or any Obligee may reasonably require,
together with legal opinions in form and substance reasonably satisfactory to
the Agent and the requesting Obligees, to be delivered to the Agent and the
Obligees opining as to authorization, validity and enforceability of such
Guaranty.

        15. Amendments and Waivers. No amendment or waiver of any provision of
this Guaranty nor consent to any departure by the Guarantor therefrom shall be

amount of the 1995 Notes, holders of 66 2/3% of the principal amount of the Nova
Notes and holders of 66 2/3% of the principal amount of the 2000 Notes. No
failure on the part of the Agent or any Obligee to exercise, and no delay in
exercising, any right hereunder shall operate as a waiver thereof; nor shall any
single or partial exercise of any right hereunder preclude any other or further
exercise thereof or the exercise of any other right.

        16. Notices. All notices and other communications called for hereunder
shall be made in writing and, unless otherwise specifically provided herein,
shall be deemed to have been duly made or given when delivered by hand or mailed

PURSUANT TO NEW YORK GENERAL OBLIGATIONS LAW Section 5-1401, BE CONSTRUED IN
ACCORDANCE WITH AND GOVERNED BY THE LAW OF THE STATE OF NEW YORK. The Guarantor

courts of the State of New York or any federal court sitting therein and
consents to the nonexclusive jurisdiction of such court and to service of
process in any such suit being made upon the Guarantor by mail at the address

that it may now or hereafter have to the venue of any such suit or any such
court or that such suit was brought in an inconvenient court.

CONNECTION WITH THIS GUARANTY, ANY RIGHTS OR OBLIGATIONS HEREUNDER OR THE
PERFORMANCE OF ANY OF SUCH RIGHTS OR OBLIGATIONS. Except as prohibited by law,
the Guarantor hereby waives any right which it may have to claim or recover in
any litigation referred to in the preceding sentence any special, exemplary,
punitive or consequential damages or any damages other than, or in addition to,
actual damages. The Guarantor (i) certifies that none of the Agent or any
Obligee, nor any representative, agent or attorney of the Agent or any Obligee
has represented, expressly or otherwise, that the Agent or any Obligee would
not, in the event of litigation, seek to enforce the foregoing waivers and (ii)
acknowledges that, in entering into the Credit Agreement, the 1995 Agreement,
the Nova Agreement, the 2000 Agreement and the other documents to which the
Agent or any Obligee is a party, the Agent and the Obligees are relying upon,
among other things, the waivers and certifications contained in this Section 18.

        19. Miscellaneous. This Guaranty constitutes the entire agreement of the
Guarantor with respect to the matters set forth herein. The rights and remedies
herein provided are cumulative and not exclusive of any remedies provided by law
or any other agreement, and this Guaranty shall be in addition to any other
guaranty of or collateral security for any of the Obligations. The invalidity or
unenforceability of any one or more sections of this Guaranty shall not affect
the validity or enforceability of its remaining provisions. Captions are for
ease of reference only and shall not affect the meaning of the relevant
provisions. The meanings of all defined terms used in this Guaranty shall be
equally applicable to the singular and plural forms of the terms defined. The
Agent represents and warrants that its signature below binds the Lenders to
their respective obligations hereunder.

    pro rata portion of any Transaction related to the Loan Agreement and will
    be entitled to receive from, or will be required to pay to, Party B the fair
    market value for such termination, as determined by Party A in good faith
    and in accordance with market practice and its own customary procedures,
    upon the occurrence of one or more of the following events:

    (a) If the indebtedness under the Loan Agreement is (for whatever reason, in
        whatever manner) partially or fully paid or discharged (except with
        respect to any scheduled amortization);
    (b) If Party A ceases to be a party to the Loan Agreement;
    (c) If the lenders party to the Loan Agreement become secured or, if already

        in its capacity as a party to this Agreement and any Transaction
        hereunder, is not entitled to the same rights, privileges, and interest
        in the collateral and/or guaranty agreements as the lenders are entitled
        to under the Loan Agreement;
    (d) If there is a default, an event of default, or other similar condition
        or event (however described) in relation to Party B under the Loan
        Agreement (without regard to the existence of any waiver or forbearance
        agreement with respect thereto); and
    (e) If the Loan Agreement is amended, restated, supplemented, or otherwise
        modified and Party A does not consent, in its sole discretion, to such
        amendment, restatement, supplement, or other modification.

    Party A may exercise such right to terminate, at any time in its sole
    discretion, following the occurrence of any one of such events through the
    Termination Date. A failure or delay in exercising the foregoing right to
    terminate will not be presumed to operate as a waiver, and a single or
    partial exercise of such right will not be presumed to preclude any
    subsequent or further exercise of that right.

     to notify (and, if required by law, obtain the consent of) its officers and
     employees with respect to such monitoring or recording.

 2.  Mediation and Arbitration. Notwithstanding anything to the contrary
     contained herein, the parties agree to submit to mediation and, should
     settlement through mediation not occur, to arbitration any and al1 claims,
     disputes, and controversies between them (and their respective employees,
     officers, directors, affiliates, attorneys, and other agents) resulting
     from or arising out of this Agreement. Such mediation and arbitration shall
     proceed in the jurisdiction where Party A is located, shall be governed by
     the law specified in this Agreement, and shall be conducted (a) in
     accordance with such rules as may be agreed upon by the parties or (b) in
     the event the parties do not reach an agreement as to such rules within
     thirty (30) days after a notice of dispute, in accordance with the
     Commercial Mediation Rules and Commercial Arbitration Rules of the American
     Arbitration Association. If, within thirty (30) days after service of a
     written demand for mediation, the mediation does not result in settlement
     of the dispute, then any party may demand arbitration, and the decision of
     the arbitrator(s) shall be binding on the parties. Judgment upon the award
     rendered by the arbitrator(s) may be entered in any court having
     jurisdiction. It is agreed that the arbitrators shall have no authority to
     award treble, exemplary, or punitive damages of any type under any
     circumstances, whether or not such damages may be available under state or
     federal law, or under the Federal Arbitration Act, or under the Commercial
     Arbitration Rules of the American Arbitration Association, the parties
     hereby waiving their right, if any, to recover any such damages.

 3.  Set Off. Section 6 of the Agreement is amended by adding the following new
     subsection 6(f):

              "(f) Right of Set-Off. Upon the occurrence of an Event of Default
              with respect to Party B, or an Illegality or Credit Event Upon
              Merger where Party B is the Affected Party, Party A will have the
              right (but not the obligation), without prior notice to Party B or
              any other person, to set-off any obligation of Party A or any of
              Party A's present or future Affiliates, branches, or offices owing
              to Party B, against any obligation of Party B owing to Party A or
              any of Party A's present or future Affiliates. branches, or
              offices (whether or not such obligations arise under this
              Agreement, whether or not matured, whether or not contingent, and
              regardless of the place of payment or booking office of the
              obligations). In order to enable Party A to exercise its rights of
              set-off, if an obligation is unascertained, Party A may in good
              faith estimate that obligation and set-off in respect of the
              estimate, subject to Party A accounting to Party B when the
              obligation is ascertained.

              Nothing in this Section 6(f) shall be effective to create a charge
              or other security interest. This Section 6(f) shall be without
              prejudice and in addition to any right of set-off, combination of
              accounts, lien, or other right to which any party is at any time
              otherwise entitled (whether by operation of law, contract, or
              otherwise)."

 4.  By signing this Schedule, Party B acknowledges that it has received and
     understands the SunTrust Bank "Terms of Dealing for OTC Risk Management
     Transactions" and the "Risk Disclosure Statement for OTC Risk Management
     Transactions" (each attached hereto and incorporated by reference into this

                            SunTrust Bank ("SunTrust")
              Terms of Dealing for OTC Risk Management Transactions

In connection with the negotiation, entry into, and performance from time to
time of over-the-counter ("OTC") risk management transactions, please be advised
that:

SunTrust acts as principal only and does not act as advisor, agent, broker, or
fiduciary for or with respect to any counterparty (unless otherwise expressly
agreed in a written engagement letter).

SunTrust expects that its counterparties have the authority and capacity to
enter into and perform their obligations under their OTC risk management
transactions with SunTrust, and SunTrust relies on the express and implied
representations of its counterparties with respect thereto.

SunTrust expects that its counterparties possess adequate knowledge and
experience to assess independently, or with the assistance of their own
advisors, the merits and risks of each OTC risk management transaction that the
counterparty may from time to time enter into, amend, or terminate.

SunTrust endeavors to maintain the confidentiality of all confidential
counterparty information and expects its counterparties to do the same. Unless a
counterparty gives SunTrust written notice to the contrary, each counterparty
authorizes SunTrust and all SunTrust affiliates, including SunTrust Capital
Markets, Inc. (STCM), to share with each other confidential information
concerning a counterparty and/or its accounts for marketing or other purposes
from time to time. Any trade ideas, term sheets, and other similar documents
sent to counterparties by SunTrust are not to be shared with others.

SunTrust may pay fees, commissions, and other amounts to agents, brokers, and/or
other third parties in connection with OTC risk management transactions entered
into with counterparties. SunTrust considers the amount of such fees,
commissions, and other amounts to be confidential and does not disclose the same
to its counterparties.

SunTrust may from time to time receive orders for similar or identical
transactions, and SunTrust makes no representation with respect to execution
priorities.

STCM's Authorized Officers have the authority to bind SunTrust in connection
with OTC risk management transactions. A current list of Authorized Officers may
be obtained from STCM upon request.

OTC risk management obligations of SunTrust are not FDIC insured.

                            SunTrust Bank ("SunTrust")
          Risk Disclosure Statement for OTC Risk Management Transactions

Over-the-counter ("OTC") risk management transactions, like other financial
transactions, involve a variety of significant potential risks. OTC risk
management transactions generally include options, forwards, swaps, swaptions,
caps, floors, collars, combination and variations of such instruments, and other
executory contractual arrangements, and may involve interest rates, currencies,
securities, commodities, equities, credit, indices, and other underlying
interests.

Before entering into any OTC risk management transaction, you should carefully
consider whether the transaction is appropriate for you in light of your
experience, objectives, financial and operational resources, and other relevant
circumstances. You should also ensure that you fully understand the nature of
the transaction and contractual relationship into which you are entering and the
nature and extent of your exposure to risk of loss, which may significantly
exceed the amount of any initial payment or investment by you.

The specific risks presented by a particular OTC risk management transaction
necessarily depend upon the character of the specific transaction and your
circumstances. In general, however, all OTC risk management transactions involve
the risk of adverse or unanticipated market developments, risk of illiquidity
and credit risk, and may involve other material risks. Equity risk management
transactions may increase or decrease in value with a change in, among other
things, stock prices and interest rates which could result in unlimited loss. In
addition, you may be subject to internal operational risks in the event that
appropriate internal systems and controls are not in place to monitor the
various risks and funding requirements to which you are subject by virtue of
your activities in the OTC risk management and related markets. OTC risk
management transactions frequently are tailored to permit parties to customize
transactions to accomplish complex financial and risk management objectives.
Such customization can also introduce significant risk factors of a complex
character.

As in any financial transaction, you must understand the requirements (including
investment restrictions), if any, applicable to you that are established by your
regulators or by your Board of Directors or other governing body. You should
also consider the tax and accounting implications of entering into any risk
management or other transaction. To the extent appropriate in light of the
specific transaction and your circumstances, you should consider consulting such
advisers as may be appropriate to assist you in understanding the risks
involved. If you are acting in the capacity of financial adviser or agent, you
must evaluate the foregoing matters in light of the circumstances applicable to
your principal.

In entering into any OTC risk management transaction, you should also take into
consideration that, unless you and SunTrust have established in writing an
express financial advisory or other fiduciary relationship or you and SunTrust
have expressly agreed in writing that you will be relying on SunTrust's
recommendations as the primary basis for making your trading or investment
decisions, SunTrust is acting solely in the capacity of an arm's-length
contractual counterparty and not in the capacity of your financial advisor or
fiduciary. In addition, SunTrust or its affiliates may from time to time have
substantial long or short positions in and may make a market in or otherwise buy
or sell instruments identical or economically related to the OTC risk management
transaction entered into with you or may have an investment banking or other
commercial relationship with the issuer of any security or financial instrument
underlying an OTC risk management transaction entered into with you.

THIS BRIEF STATEMENT DOES NOT DISCLOSE ALL OF THE RISKS AND OTHER SIGNIFICANT
ASPECTS OF ENTERING INTO OTC RISK MANAGEMENT TRANSACTIONS. YOU SHOULD REFRAIN
FROM ENTERING INTO ANY SUCH TRANSACTION UNLESS YOU FULLY UNDERSTAND ALL SUCH
RISK AND HAVE INDEPENDENTLY DETERMINED THAT THE TRANSACTION IS APPROPRIATE FOR
YOU.

Equalization Plan as it does with respect to the Pension Plan.

5.   General

5.1  The Equalization Plan may be amended or terminated at any time by the Board
     of Directors of the Company, except that no such amendment or termination
     shall adversely affect the benefits payable to any person who has begun to
     receive benefits hereunder.

5.2  Benefits payable hereunder shall not be funded and shall be paid out of the
     general assets of the Company.

5.3  The Equalization Plan shall be construed, administered and enforced
     according to the laws of the State of Connecticut.
