                         ARTICLE 2. THE REVOLVING CREDIT

         Section 2.1. The Revolving Credit.

                  (a) Subject to the terms and conditions of this Agreement and
so long as there exists no Default, at any time prior to the Revolving Credit
Termination Date, each Lender, severally and not jointly, shall make such
Revolving Credit Advances to the Borrowers as the Borrowers may from time to
time request, by notice to the Agent in accordance with Section 2.2, in an
aggregate amount (i) as to each Lender, not to exceed at any time such Lender's
Commitment Percentage of the Maximum Revolving Credit Amount, and (ii) as to all
Lenders, not to exceed the Maximum Revolving Credit Amount minus (B) the amount
available to be drawn under all Letters of Credit. The outstanding principal
amount of the Revolving Credit Advances, together with all accrued interest and
other fees and charges related thereto, shall be repaid in full on the Revolving
Credit Termination Date. On the Closing Date, the Borrowers, jointly and
severally, shall execute and deliver to each Lender a Revolving Credit Note to
evidence the Revolving Credit Advances from time to time made by such Lender to
the Borrower hereunder.

                  (b) Subject to the foregoing limitations and the provisions of
Section 4.2, the Borrowers shall have the right to make prepayments reducing the
outstanding balance of


                                       13
<PAGE>   19
Revolving Credit Advances and to request further Revolving Credit Advances, all
in accordance with Section 2.2, without other restrictions hereunder; provided
that the Lenders shall have the absolute right to refuse to make any Revolving
Credit Advances for so long as there exists any Default or any other condition
which would constitute a Default upon the making of such a Revolving Credit
Advance.

                  (c) Notwithstanding anything to the contrary contained herein
or in any of the Security Documents, upon the occurrence and during the
continuance of any Event of Default, Tweeter and its Subsidiaries will hold in
trust for the Agent all checks, drafts, cash and other remittances that are
proceeds of the Collateral and will deliver the same to the Agent in the form
received, together with the proper endorsement thereon. The Agent will credit
all such payments (conditional upon final collection) against interest accrued
on or principal of the Revolving Credit Advances outstanding hereunder. The
order and method of application shall be in the Agent's sole discretion and
proceeds which in the Agent's discretion are not so applied shall be credited to
Tweeter's deposit accounts with the Agent. So long as any Default exists, the
Agent will at all times have the right to require Tweeter and its Subsidiaries
to enter into one or more blocked account and lockbox arrangements with the
Agent for the collection of such remittances and payments.

                  (d) Notwithstanding anything to the contrary contained herein
or in any of the Security Documents, the Agent may (i) at any time, in its own
name or in the name of others, communicate with account debtors in order to
verify with them, to the Agent's satisfaction, the existence, amount and terms
of any Accounts Receivable and the absence of any reductions, discounts,
defenses or offsets with respect thereto, provided, however, that prior to the
occurrence of an Event of Default, the Agent shall communicate with such account
debtors only in the name of others and not in its own name and (ii) so long as
any Default exists, notify account debtors that Collateral has been assigned to
the Agent and that payments by such debtors shall be made directly to the Agent.
At the Agent's request, so long as any Default exists, Tweeter and its
Subsidiaries will notify any or all such debtors of such assignment, give
instructions and/or indicate on billings to such debtors that their Accounts
Receivable shall be paid to the Agent.

         Section 2.2. Making of Revolving Credit Advances.

                  (a) Each Revolving Credit Advance shall be made on notice
given by New England Audio to the Agent not later than 12:00 noon (Boston time)
on the date of the proposed Borrowing (a "Notice of Revolving Credit
Borrowing"); provided, however that if the Borrowers elect a Eurodollar Pricing
Option with respect to any Revolving Credit Advance in accordance with Section
2.4 hereof, such Notice of Revolving Credit Borrowing shall be given by New
England Audio contemporaneously with a Eurodollar Pricing Notice in the manner
and within the time specified in Section 2.4. The Agent shall give the Lenders
notice of each Notice of Revolving Credit Borrowing in accordance with the
Agent's customary practice. Each such Notice of Revolving Credit Borrowing shall
be by telephone or telecopy, in each case confirmed immediately in writing by
New England Audio in substantially the form


                                       14
<PAGE>   20
of Exhibit B hereto, specifying therein (i) the requested date of such Revolving
Credit Advance and (ii) the amount of such Revolving Credit Advance (which must
be a minimum of $100,000). The Borrowers, jointly and severally, agree to
indemnify and hold the Lenders harmless for any action, including the making of
any Revolving Credit Advances hereunder, or loss or expense, taken or incurred
by the Agent and the Lenders in good faith reliance upon such telephone request.
At the time of the initial request for a Revolving Credit Advance made under
this Section 2.2, the Borrowers shall have provided the Agent with a Compliance
Certificate. The Borrowers, jointly and severally, hereby agree (A) that the
Lenders shall be entitled to rely upon the Compliance Certificate most recently
delivered to the Agent until it is superseded by a more recent Compliance
Certificate and (B) that each request for a Revolving Credit Advance, whether by
telephone or in writing or otherwise, shall constitute a confirmation of the
representations and warranties contained in the most recent Compliance
Certificate then in the Agent's possession.

                  (b) Subject to the terms and conditions of this Agreement,
each Lender shall make available on or before 2:00 p.m., Boston time, on the
date of each proposed Revolving Credit Advance, to the Agent at the Agent's
address and in immediately available funds, such Lender's Commitment Percentage
of such Revolving Credit Advance. After the Agent's receipt of such funds and
upon fulfillment of the applicable conditions set forth in Article 3, the Agent
will credit such funds to New England Audio's account on the date of the
proposed Revolving Credit Advance.

                  (c) Unless the Agent shall have received notice from a Lender
prior to the date of any Revolving Credit Advance that such Lender will not make
available to the Agent such Lender's Commitment Percentage of such Revolving
Credit Advance, the Agent may assume that such Lender has made such amount
available to the Agent on the date of such Revolving Credit Advance in
accordance with and as provided in this Section 2.2 and the Agent may, in
reliance upon such assumption, make available on such date a corresponding
amount to the Borrowers. If and to the extent such Lender shall not have so made
its Commitment Percentage of such Revolving Credit Advance available to the
Agent and the Agent shall have made available such corresponding amount to the
Borrowers, such Lender agrees to pay to the Agent forthwith on demand, and the
Borrowers, jointly and severally, agree to repay to the Agent within two
Business Days after demand (but only after demand for payment has first been
made to such Lender and such Lender has failed to make such payment), an amount
equal to such corresponding amount together with interest thereon for each day
from the date the Agent shall make such amount available to the Borrowers until
the date such amount is paid or repaid to the Agent, at an interest rate equal
to the interest rate applicable at the time to such Revolving Credit Advances.
If such Lender shall pay to the Agent such corresponding amount, such amount so
paid shall constitute such Lender's Revolving Credit Advance for purposes of
this Agreement. If the Borrowers make a repayment required by the foregoing
provisions of this Section 2.2(c) and thereafter the applicable Lender or
Lenders make the payments to the Agent required by this Section 2.2(c), the
Agent shall promptly refund the amount of the Borrowers' payment.


                                       15
<PAGE>   21
                  (d) The failure of any Lender to make the Revolving Credit
Advance to be made by it on any date shall not relieve any other Lender of its
obligation, if any, hereunder to make its Revolving Credit Advance on such date,
but no Lender shall be responsible for the failure of any other Lender to make
the Revolving Credit Advance to be made by such other Lender.

         Section 2.3. Interest on Revolving Credit Advances. Subject to the
terms of Section 2.4 relating to Eurodollar Pricing Options, the Borrowers,
jointly and severally, shall pay interest on the unpaid balance of the Revolving
Credit Advances from time to time outstanding at a per annum rate equal to the
Applicable Base Rate. Interest on the Revolving Credit Advances shall be payable
quarterly in arrears on the first day of each January, April, July and October,
commencing July 1, 1998 and continuing until all of the Indebtedness of the
Borrower to the Lenders under the Revolving Credit Notes shall have been paid in
full. Interest accrued under the 1997 Credit Agreement to the date hereof shall
be paid on the date or dates for such payment set forth in the 1997 Credit
Agreement.

         Section 2.4. Election of Eurodollar Pricing Options.

                  (a) Subject to all the terms and conditions hereof and so long
as there exists no Default, New England Audio may, by delivering a notice (each
a "Eurodollar Pricing Notice") to the Agent received at or before 10:00 a.m.
Boston time on the date three Business Days prior to the commencement of the
Interest Period selected in such Eurodollar Pricing Notice, elect to have all or
a portion of the outstanding Revolving Credit Advances, as New England Audio may
specify in such Eurodollar Pricing Notice, accrue and bear daily interest during
the Interest Period so selected at a per annum rate equal to the Applicable
Eurodollar Rate for such Interest Period; provided, however, that any such
election made with respect to the Revolving Credit Advances shall be in an
amount not less than $500,000 and in increments of $100,000; and provided
further that no such election will be made if it would result in there being
more than eight (8) Eurodollar Pricing Options in the aggregate outstanding at
any one time. Interest on Loans bearing interest at the Applicable Eurodollar
Rate shall be paid for the applicable Interest Period on the last day thereof,
at intervals of three months after the first day of any Interest Period which is
longer than three months, and when such Loan is due (whether at maturity, by
reason of acceleration or otherwise).

                  (b) Each Eurodollar Pricing Notice shall be substantially in
the form of Exhibit D attached hereto and shall specify: (i) the selection of a
Eurodollar Pricing Option, (ii) the effective date and amount of Revolving
Credit Advances subject to such Eurodollar Pricing Option, subject to the
limitations set forth herein, and (iii) the duration of the applicable Interest
Period. Each Eurodollar Pricing Notice shall be irrevocable.

                  (c) The Agent will promptly inform each Lender of a Eurodollar
Pricing Notice and the Interest Period specified by New England Audio therein.
Upon determination by the Agent of the Applicable Eurodollar Rate for any
Interest Period selected by New England Audio, the Agent will promptly inform
New England Audio and each Lender of such


                                       16
<PAGE>   22
Applicable Eurodollar Rate so determined or, if applicable, the reason why New
England Audio's election will not become effective. The Applicable Eurodollar
Rate shall become effective on the first day of the Applicable Interest Period
provided no Default exists at such time.

         Section 2.5. Additional Payments. During the continuance of any Event
of Default under Section 10.1(a) hereof or resulting from a violation of any
covenant contained in Article 7 or 9 hereof, the Borrowers shall, jointly and
severally, on demand, pay to the Agent for the account of the Lenders, interest
on the unpaid principal balance of the Revolving Credit Advances and, to the
extent permitted by law, on any overdue installments of interest, at a rate per
annum equal to the lesser of (i) the stated interest rates applicable thereto
plus 2% per annum and (ii) the maximum rate of interest permitted to be charged
under applicable law.

         Section 2.6. Computation of Interest, Etc. Interest hereunder and under
the Revolving Credit Advances shall be computed on the basis of a 360-day year
for the number of days actually elapsed. Any increase or decrease in the
interest rate on the Revolving Credit Advances resulting from a change in the
Base Rate shall be effective immediately from the date of such change. No
interest payment or interest rate charged hereunder shall exceed the maximum
rate authorized from time to time by applicable law. The outstanding balance of
the Revolving Credit Notes as reflected on the Agent's records from time to
time, if made in good faith, shall be considered correct and binding on the
Borrowers and the Lenders (absent manifest error) unless within ninety (90) days
after receipt of any notice by the Agent or any Lender of such outstanding
amount, New England Audio or a Lender notifies the Agent to the contrary.

         Section 2.7. Fees

                  (a) The Borrowers, jointly and severally, shall pay to the
Agent, for the accounts of the Lenders in accordance with their respective
Commitment Percentages, a commitment fee (the "Revolving Commitment Fee")
computed at a rate equal to the Applicable Commitment Fee on the average daily
unused amount of the Maximum Revolving Credit Amount from time to time in effect
from the date hereof to and including the Revolving Credit Termination Date. The
Revolving Commitment Fee shall be payable quarterly in arrears on the first day
of each January, April, July and October, commencing July 1, 1998, for the
quarter then ended. Commitment fees accrued under the 1997 Credit Agreement to
the date hereof shall be paid on July 1, 1998.

                  (b) The Borrowers, jointly and severally, shall pay to the
Agent, for the Agent's own account, such closing and agency fees as are provided
in a letter agreement dated May 30, 1997 between the Borrowers and the Agent (as
supplemented on June 23, 1998 and as such letter agreement may from time to time
be amended or further supplemented, the "Fee Letter").


                                       17
<PAGE>   23
         Section 2.8. Set-Off. To the extent not prohibited by applicable law,
each Loan Party hereby authorizes the Agent and each Lender, without notice to
any Loan Party, if and to the extent payment is not promptly made when due
pursuant to the Revolving Credit Notes or pursuant to any provision hereof or of
any other Lender Agreement, to charge against any account of such Loan Party
with the Agent or such Lender, an amount equal to the accrued interest and
principal and other amounts from time to time then due and payable to the Agent
and the Lenders hereunder and under all other Lender Agreements.

         Section 2.9. Sharing of Payments. If any Lender shall obtain any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off, or otherwise) on account of the Loans made by it in excess of its
ratable share (according to the then outstanding principal amount of the Loans)
of payments on account of the Loans obtained by all the Lenders, such Lender
shall purchase from the other Lenders such participations in the Loans held by
such other Lenders as shall cause such purchasing Lender to share such payment
ratably according to the then outstanding principal amount of the Loans with
each of such other Lenders; provided, however, that if all or any portion of
such payment is thereafter recovered from such purchasing Lender, the purchase
shall be rescinded and the purchase price restored to the extent of such
recovery, with interest at an interest rate per annum equal to the Applicable
Base Rate. The Borrowers agree that any Lender so purchasing a participation in
the Loans from another Lender pursuant to this Section 2.9 may, to the fullest
extent permitted by law, exercise all its rights of payment with respect to such
participation as fully as if such Lender were the direct creditor of each
Borrower in the amount of such participation.

         Section 2.10. Reduction of Commitment by the Borrowers. New England
Audio, as agent for the Borrowers, at its option may, at any time and from time
to time, irrevocably reduce in part (in an amount not less than $1,000,000 and
in integral multiples of $1,000,000) the unused portion of the Maximum Revolving
Credit Amount on not less than seven (7) days' prior written notice to the
Agent. No such reduction, may be reinstated by the Borrowers.

         Section 2.11. Letters of Credit.

                  (a) Subject to the terms and conditions hereof, including
satisfaction of the conditions set forth in Sections 3.1 and 3.2 hereof, and
provided no Default exists and that the Issuing Bank is then generally issuing
letters of credit for its banking customers, the Issuing Bank shall at any time
prior to the Revolving Credit Termination Date, upon the request of New England
Audio pursuant to paragraph (b) below, issue Letters of Credit for the account
of New England Audio, provided that the aggregate face amount of all outstanding
Letters of Credit shall not at any time exceed $5,000,000.

                  (b) New England Audio may request that the Issuing Bank issue
a Letter of Credit by written notice (the "Letter of Credit Notice") given by
New England Audio to the Issuing Bank not less than five (5) Business Days prior
to the proposed date of issuance of such Letter of Credit. The Letter of Credit
Notice shall (i) specify the proposed date of issuance,


                                       18
<PAGE>   24
the beneficiary and amount of such Letter of Credit and (ii) be accompanied by a
completed letter of credit application furnished by the Issuing Bank.

                  (c) The Borrowers hereby agree, jointly and severally, to pay
to the Issuing Bank on the date on which the Issuing Bank shall be required to
pay any draft presented under any Letter of Credit, a sum (the "Reimbursement
Amount") equal to: (i) the amount so paid under such Letter of Credit, plus (ii)
interest on any amount remaining unpaid by the Borrower to the Issuing Bank
under clause (i) from and including the date on which such amount becomes
payable pursuant to clause (i) until payment in full, payable on demand, at a
per annum rate of interest equal to the rate applicable to the Revolving Credit
Advances under Section 2.3. If the Borrowers shall fail to pay to the Issuing
Bank the Reimbursement Amount on the date on which the Issuing Bank shall be
required to pay any draft presented under any Letter of Credit, the Issuing Bank
shall, to the extent the Borrowers have availability to request a Revolving
Credit Advance, consider such failure to be a request for a Revolving Credit
Advance in the amount of the unpaid Reimbursement Amount (which request shall be
deemed a confirmation that the conditions set forth in Section 3.2 have been
satisfied), and the Agent shall apply the proceeds of such Revolving Credit
Advance to reimburse the Issuing Bank for the Reimbursement Amount.

                  (d) The Borrowers shall, jointly and severally, pay a fee (in
each case, a "Letter of Credit Fee") to the Agent in respect of each Letter of
Credit outstanding in an amount per annum equal to the then applicable
Eurodollar Rate Margin multiplied by the average daily amount available to be
drawn under such Letter of Credit payable on the first day of each January,
April, July and October, for the calendar quarter or portion thereof ending
immediately prior thereto. The Agent shall, in turn, remit to each Lender its
pro rata portion of such Letter of Credit Fee. In addition, if there is more
than one Lender hereunder, the Borrowers, jointly and severally, shall pay to
the Issuing Bank, for its own account, on the date of issuance, or any extension
or renewal of any Letter of Credit and at such other time or times as such
charges are customarily made by the Issuing Bank, a fronting fee equal to
one-eighth percent (1/8%) of the face amount of such Letter of Credit and, from
time to time, the Issuing Bank's standard issuance, processing, negotiation,
amendment and administrative fees, determined in accordance with customary fees
and charges for similar facilities.

                  (e) Each payment by the Borrowers under this Section 2.11
shall be made to the Issuing Bank at the Issuing Bank's head office in
immediately available funds. Interest on any and all amounts remaining unpaid by
the Borrowers under this Section 2.11 at any time from the date such amounts
become due and payable (whether as stated in this Section 2.11, by acceleration
or otherwise) until payment in full (whether before or after judgment) shall be
payable to the Issuing Bank on demand at the rate specified in Section 2.5(a)
for the overdue principal on the Loans.

                  (f) The obligations of the Borrowers with respect to the
Letters of Credit shall be unconditional and irrevocable, and shall be paid
strictly in accordance with the terms


                                       19
<PAGE>   25
of this Agreement under all circumstances, including, without limitation, the
following circumstances:

                  (i) any lack of validity or enforceability of the Letters of
         Credit;

                  (ii) any amendment or waiver of or any consent to or actual
         departure from this Agreement;

                  (iii) the existence of any claim, set-off, defense or other
         right which the Borrowers may have at any time against any beneficiary
         or any transferee of a Letter of Credit (or any Persons or entities for
         which any such beneficiary or any such transferee may be acting), the
         Issuing Bank or any other Person or entity, whether in connection with
         this Agreement, the transactions contemplated herein or in any other
         agreements or any unrelated transaction;

                  (iv) any statement or any other document presented under a
         Letter of Credit proving to be forged, fraudulent, invalid or
         insufficient in any respect or any statement therein being untrue or
         inaccurate in any respect;

                  (v) payment by the Issuing Bank under a Letter of Credit
         against presentation by the beneficiary thereof of a draft or
         certificate which does not comply with the terms of such Letter of
         Credit; or

                  (vi) any other circumstance or happening whatsoever, whether
         or not similar to any of the foregoing.

         (g) The Uniform Customs and Practice shall be binding on the Borrowers,
the Lenders and the Issuing Bank. The Borrowers assume all risks of the acts or
omissions of the beneficiary of each Letter of Credit with respect to such
Letter of Credit. In furtherance of, and not in limitation of the Issuing Bank's
rights and powers under the Uniform Customs and Practice, but subject to all
other provisions of this paragraph (g), it is understood and agreed that the
Issuing Bank shall not have any liability for, and that the Borrowers assume all
responsibility for: (i) the genuineness of any signature; (ii) the form,
correctness, validity, sufficiency, genuineness, falsification and legal effect
of any draft, certification or other document required by a Letter of Credit or
the authority of the Person signing the same; (iii) the failure of any
instrument to bear any reference or adequate reference to a Letter of Credit or
the failure of any Persons to note the amount of any instrument on the reverse
of a Letter of Credit or to surrender a Letter of Credit or otherwise to comply
with the terms and condition of a Letter of Credit; (iv) the good faith or acts
of any Person other than the Issuing Bank and its agents and employees; (v) the
existence, form or sufficiency or breach or default under any agreement or
instrument of any nature whatsoever; (vi) any delay in giving or failure to give
any notice, demand or protest; and (vii) any error, omission, delay in or
nondelivery of any notice or other communication, however sent. The
determination as to whether the required


                                       20
<PAGE>   26
documents are presented prior to the expiration of a Letter of Credit and
whether such other documents are in proper and sufficient form for compliance
with a Letter of Credit shall be made by the Issuing Bank in its discretion in
accordance with the Uniform Customs and Practice, which determination shall be
conclusive and binding upon the Borrower absent manifest error. It is agreed
that the Issuing Bank may honor, as complying with the terms of a Letter of
Credit and this Agreement, any documents otherwise in order and signed or issued
by the beneficiary thereof. Any action, inaction or omission on the part of the
Issuing Bank under or in connection with the Letters of Credit or any related
instruments or documents, if in good faith and in conformity with such laws,
regulations or commercial or banking customs as the Issuing Bank may reasonably
deem to be applicable, shall be binding upon the Borrowers, shall not place the
Issuing Bank under any liability to the Borrowers, and shall not affect, impair
or prevent the vesting of any of the Issuing Bank's rights or powers hereunder
or the Borrowers' obligation to make full reimbursement of amounts drawn under
the Letters of Credit.

                  (h) If New England Audio, either in writing or orally,
requests or consents to any modification or extension of a Letter of Credit or
waives failure of any draft, certificate or other documents to comply with the
terms of a Letter of Credit, the Issuing Bank shall be entitled to rely and
shall be deemed to have relied on such request, consent or waiver with respect
to any action taken or omitted by the Issuing Bank pursuant to any such request,
consent or waiver, and such extension, modification or waiver shall be binding
upon the Borrowers.

                  (i) Each Lender severally agrees that it shall be absolutely
liable, without regard to the occurrence of any Default or Event of Default or
any other condition precedent whatsoever, to the extent of such Lender's
Commitment Percentage, to reimburse the Issuing Bank on demand for the amount of
each draft paid by the Issuing Bank under each Letter of Credit to the extent
that such amount is not reimbursed by the Borrowers pursuant to paragraph (c)
above (such agreement for a Lender being called herein the "Letter of Credit
Participation" of such Lender).

                  (j) If any draft shall be presented or other demand for
payment shall be made under any Letter of Credit, the Issuing Bank shall notify
New England Audio of the date and amount of the draft presented or demand for
payment and of the date and time when it expects to pay such draft or honor such
demand for payment. If the Borrowers fail to reimburse the Issuing Bank as
provided in paragraph (c) above on or before the date that such draft is paid or
other payment is made by the Issuing Bank, the Issuing Bank may at any time
thereafter notify the Lenders of the amount of any such unpaid Reimbursement
Amount. No later than 3:00 p.m. (Boston time) on the Business Day next following
the receipt of such notice, each Lender shall make available to the Issuing
Bank, at its head office located at 100 Federal Street, Boston, Massachusetts,
in immediately available funds, such Lender's Commitment Percentage of such
unpaid Reimbursement Amount, together with an amount equal to the product of (i)
the average, computed for the period referred to in clause (iii) below, of the
weighted average interest rate paid by the Issuing Bank for federal funds


                                       21
<PAGE>   27
acquired by the Issuing Bank during each day included in such period, times (ii)
the amount equal to such Lender's Commitment Percentage of such unpaid
Reimbursement Amount, times (iii) a fraction, the numerator of which is the
number of days that elapse from and including the date the Issuing Bank paid the
draft presented for honor or otherwise made payment to the date on which such
Lender's Commitment Percentage of such unpaid Reimbursement Amount shall become
immediately available to the Issuing Bank, and the denominator of which is 360.

                  (k) Neither the Issuing Bank nor any of its officers,
directors or employees shall be liable or responsible for: (i) the use which may
be made of any Letter of Credit or any acts or omissions of any beneficiary or
transferee in connection therewith; (ii) the validity, sufficiency or
genuineness of documents, or of any endorsement thereon, even if such documents
should prove to be in any or all respects invalid, insufficient, fraudulent or
forged; (iii) payment by the Issuing Bank against presentation of documents
which do not comply with the terms of a Letter of Credit, including failure of
any documents to bear any reference or adequate reference to a Letter of Credit;
or (iv) any other circumstances whatsoever in making or failure to make payment
under a Letter of Credit; provided, that, notwithstanding anything in this
Section 2.11 to the contrary, New England Audio shall have a claim against the
Issuing Bank, and the Issuing Bank shall be liable to New England Audio, to the
extent, but only to the extent, of any direct, as opposed to consequential,
damages suffered by New England Audio which were caused by the Issuing Bank's
failure to conform to the standards of the Uniform Customs and Practice. In
furtherance and not in limitation of the foregoing, the Issuing Bank may accept
documents that appear on their face to be in order, without responsibility for
further investigation, regardless of any notice or information to the contrary.

         Section 2.12. Increased Costs, Etc.

                  (a) Anything herein to the contrary notwithstanding, if any
changes in present or future applicable law (which term "applicable law," as
used in this Agreement, includes statutes and rules and regulations thereunder
and interpretations thereof by any competent court or by any governmental or
other regulatory body or official charged with the administration or the
interpretation thereof and requests, directives, instructions and notices at any
time or from time to time heretofore or hereafter made upon or otherwise issued
to any Lender by any central bank or other fiscal, monetary or other authority,
whether or not having the force of law), including without limitation any change
according to a prescribed schedule of increasing requirements, whether or not
known or in effect as of the date hereof, shall (i) subject such Lender to any
tax, levy, impost, duty, charge, fee, deduction or withholding of any nature
with respect to this Agreement or the payment to such Lender of any amounts due
to it hereunder, or (ii) materially change the basis of taxation of payments to
such Lender of the principal of or the interest on the Revolving Credit Advances
or any other amounts payable to such Lender hereunder, or (iii) impose or
increase or render applicable any special or supplemental deposit or reserve or
similar requirements or assessment against assets held by, or deposits in or for
the account of, or any liabilities of, or loans by an office of such Lender in
respect of the transactions contemplated herein, or (iv) impose on such Lender
any other condition or requirement with respect to this Agreement, any Revolving
Credit Advance or any


                                       22
<PAGE>   28
Letter of Credit, and the result of any of the foregoing is (A) to increase the
cost to such Lender of making, funding or maintaining all or any part of the
Revolving Credit Advances, the Letters of Credit or its commitments hereunder,
or (B) to reduce the amount of principal, interest or other amount payable to
such Lender hereunder, or (C) to require such Lender to make any payment or to
forego any interest or other sum payable hereunder, the amount of which payment
or foregone interest or other sum is calculated by reference to the gross amount
of any sum receivable or deemed received by such Lender from the Borrowers
hereunder, then, and in each such case not otherwise provided for hereunder, the
Borrowers, jointly and severally, will upon demand made by such Lender promptly
following such Lender's receipt of notice pertaining to such matters accompanied
by calculations thereof in reasonable detail, pay to such Lender such additional
amounts as will be sufficient to compensate such Lender for such additional
cost, reduction, payment or foregone interest or other sum; provided that the
foregoing provisions of this sentence shall not apply in the case of any
additional cost, reduction, payment or foregone interest or other sum resulting
from any taxes charged upon or by reference to the overall net income, profits
or gains of any Lender. In determining the additional amounts payable hereunder,
the Lenders may use any reasonable method of averaging, allocating or
attributing such additional costs, reductions, payments, foregone interest or
other sums among their respective customers.

                  (b) Anything herein to the contrary notwithstanding, if, after
the date hereof, any Lender shall have determined that any present or future
applicable law, rule, regulation, guideline, directive or request (whether or
not having force of law), including without limitation any change according to a
prescribed schedule of increasing requirements, whether or not known or in
effect as of the date hereof, regarding capital requirements for banks or bank
holding companies generally, or any change therein or in the interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by such Lender with any of the foregoing, either imposes a requirement upon such
Lender to allocate additional capital resources or increases such Lender's
requirement to allocate capital resources or such Lender's commitment to make,
or to such Lender's maintenance of, the Revolving Credit Advances or the Letters
of Credit hereunder, which has or would have the effect of reducing the return
on such Lender's capital to a level below that which such Lender could have
achieved (taking into consideration such Lender's then existing policies with
respect to capital adequacy and assuming full utilization of such Lender's
capital) but for such applicability, change, interpretation, administration or
compliance, by any amount deemed by such Lender to be material, such Lender
shall promptly after its determination of such occurrence give notice thereof to
the Borrowers. The Borrowers and such Lender shall thereafter attempt to
negotiate in good faith an adjustment to the compensation payable hereunder
which will adequately compensate such Lender for such reduction. If the
Borrowers and such Lender are unable to agree to such adjustment within thirty
(30) days of the day on which the Borrowers receive such notice, then commencing
on the date of such notice (but not earlier than the effective date of any such
applicability, change, interpretation, administration or compliance), the fees
payable hereunder shall increase by an amount which will, in such Lender's
reasonable determination, evidenced by calculations in reasonable detail
furnished to the Borrowers,


                                       23
<PAGE>   29
compensate such Lender for such reduction, such Lender's determination of such
amount, if made in good faith, to be conclusive and binding upon the Borrowers,
absent manifest error. In determining such amount, such Lender may use any
reasonable methods of averaging, allocating or attributing such reduction among
its customers.

         Section 2.13. Changed Circumstances. In the event that:

                  (a) on any date on which the Applicable Eurodollar Rate would
otherwise be set, the Agent shall have determined in good faith (which
determination shall be final and conclusive) that adequate and fair means do not
exist for ascertaining the Eurodollar Rate, as applicable; or

                  (b) at any time the Agent shall have determined in good faith
(which determination shall be final and conclusive) that

                           (i) the implementation of the Eurodollar Pricing
         Option has been made impracticable or unlawful by (A) the occurrence of
         a contingency that materially and adversely affects the London
         interbank market or (B) compliance by any Lender in good faith with any
         applicable law or governmental regulation, guideline or order or
         interpretation or change thereof by any governmental authority charged
         with the interpretation or administration thereof or with any request
         or directive of any such governmental authority (whether or not having
         the force of law); or

                           (ii) the Eurodollar Rate shall no longer represent
         the effective cost to the Lenders for U.S. dollar deposits in the
         London interbank market, as applicable for deposits in which they
         regularly participate;

then, and in such event, the Agent shall forthwith so notify the Borrowers
thereof. Until the Agent notifies the Borrowers that the circumstances giving
rise to such notice no longer apply, the obligation of the Lenders and the Agent
to allow election by the Borrowers of a Eurodollar Pricing Option shall be
suspended. If at the time the Agent so notifies the Borrowers, New England Audio
has previously given the Agent a Eurodollar Pricing Notice with respect to a
Eurodollar Pricing Option, but the Eurodollar Pricing Option requested therein
has not yet gone into effect, such Eurodollar Pricing Notice shall automatically
be deemed to be withdrawn and be of no force or effect. Upon such date as shall
be specified in such notice (which shall not be earlier than the date such
notice is given), the Eurodollar Pricing Option with respect to all Eurodollar
Rate Loans shall be terminated and the Borrowers, jointly and severally, shall
pay all interest due on such Eurodollar Rate Loans and any amounts required to
be paid pursuant to Section 4.3.

         Section 2.14. Use of Proceeds. The proceeds of all Revolving Credit
Advances shall be used by the Borrowers for general working capital and other
corporate purposes including capital expenditures and Permitted Acquisitions
permitted hereunder. The Borrowers will not, directly or indirectly, use any
part of such proceeds for the purpose of purchasing or carrying


                                       24
<PAGE>   30
any margin stock within the meaning of Regulation U of the Board of Governors of
the Federal Reserve System or to extend credit to any Person for the purpose of
purchasing or carrying any such margin stock.

         Section 2.15. Guaranty. The Guarantors, jointly and severally, hereby
unconditionally guaranty to the Agent and the Lenders the full and punctual
payment when due (whether at maturity, by acceleration or otherwise), and the
performance of (a) all liabilities, agreements, obligations and Indebtedness,
direct or indirect, matured or unmatured, primary or secondary, certain or
contingent, secured or unsecured of the Borrowers to the Agent and the Lenders
(including without limitation, costs and expenses incurred by the Agent and the
Lenders in attempting to collect or enforce any of the foregoing), including
without limitation the Lender Obligations, accrued in each case to the date of
payment and (b) the performance of all other agreements, covenants and
conditions of the Borrowers with respect thereto set forth in this Agreement and
all other Lender Agreements. The responsibilities and obligations of the
Borrowers to the Agent and the Lenders described in the preceding sentence are
hereinafter referred to collectively as the "Guaranteed Obligations." The
guaranty pursuant to this Section 2.17 is an absolute, unconditional, joint and
several, and continuing guaranty of the full and punctual payment and
performance by the Borrowers of the Guaranteed Obligations and not of
collectability of the Guaranteed Obligations, and is in no way conditioned upon
any requirement that the Agent or the Lenders first attempt to collect any of
the Guaranteed Obligations from the Borrowers or resort to any security or other
means of obtaining payment of any of the Guaranteed Obligations which the Agent
or the Lenders now has or may acquire after the date hereof, or upon any other
contingency whatsoever. Upon any default by the Borrowers in respect of the full
and punctual payment and performance of the Guaranteed Obligations which
constitutes an Event of Default, the liabilities and obligations of each
Guarantor hereunder shall, at the option of the Agent, become forthwith due and
payable to the Agent and the Lenders without demand or notice of any nature, all
of which are expressly waived by each Guarantor. Payments by each Guarantor
under this Section 2.15 may be required by the Agent or the Lenders on any
number of occasions. Each Guarantor waives presentment, demand, protest, notice
of acceptance, notice of Guaranteed 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 marshaling of assets of the Borrowers and all suretyship defenses
generally. Without limiting the generality of the foregoing, each Guarantor
agrees to the provisions of any instrument evidencing, securing or otherwise
executed in connection with any Guaranteed Obligations and agrees that the
obligations of each Guarantor hereunder shall not be released or discharged, in
whole or in part, or otherwise affected by any rescissions, waivers, amendments
or modifications of any of the terms or provisions of any agreement evidencing
securing or otherwise executed in connection with any Guaranteed Obligation.
Until the payment and performance in full of all Guaranteed Obligations and any
and all obligations of the Borrowers to any affiliate of the Agent or the
Lenders, no Guarantor shall exercise any rights against the Borrowers arising as
a result of payment by any Guarantor hereunder, by way of subrogation or
otherwise. The payment of any amounts due with respect to any


                                       25
<PAGE>   31
indebtedness of the Borrowers now or hereafter held by each Guarantor is hereby
subordinated to the prior payment in full of the Guaranteed Obligations.

their respective Commitment Percentages. Any payment made by the Borrowers to
the Agent under this Agreement or under the Notes in the manner provided in this

shall be solely for the account of the Agent or any specific Lender.

         Section 4.6. Payments Not at End of Interest Period. If the Borrowers
for any reason make any payment of principal with respect to any Eurodollar Rate
Loan on any day other than the last day of the Interest Period applicable to

a result of such payment or failure to borrow, including without limitation, any
loss, including lost profits, costs or expenses incurred by reason of the
liquidation, reutilization or reemployment of deposits or other funds acquired
by the Lenders to fund or maintain such Revolving Credit Advances. Such
compensation may include, without limitation, an amount equal to (a) the amount
of interest which would have accrued on the amount so paid or not borrowed, for
the period from the date of such payment or failure to borrow, to the last day
of the then current Interest Period for such Revolving Credit Advance (or, in
the case of a failure to borrow, to the last day of the Interest Period for the
Revolving Credit Advance which would have commenced on the date of such failure
to borrow), at the applicable rate of interest for such Revolving Credit Advance
provided for herein minus (b) the amount of interest (as reasonably determined
by the Agent), which would accrue and become payable to the Lenders during such
period on the principal repaid or not borrowed if the Lenders, following such
repayment or failure to borrow, were to reinvest such principal in U.S. Treasury
securities selected by the Agent in an amount equal (as nearly as may be) to the
principal so repaid or not borrowed and having a term equal (as near as may be)
to such period. The Borrowers shall pay such amount upon presentation by the

agency pending or, to the knowledge of Tweeter, threatened, or any basis
therefor, which involves a risk of any judgment or liability which, if adversely
determined, would have a Material Adverse Effect, and no judgment, decree, or
order of any federal, state, provincial or municipal court, board or other
governmental or administrative agency has been issued against Tweeter or any
Subsidiary which has or may have a Material Adverse Effect.

maintained by Tweeter or any Subsidiary or any other Person a member of the same

Tweeter or any Subsidiary contributes) which is subject to Part 3 of Subtitle B
of Title I of the ERISA, had a material accumulated funding deficiency (as such
term is defined in Section 302 of ERISA) as of the last day of the most recent
fiscal year of such plan ended prior to the date hereof, or would have had an
accumulated funding deficiency (as so defined) on such day if such year were the
first year of such plan to which Part 3 of Subtitle B of Title I of ERISA
applied, and no material liability under Title IV of ERISA has been, or is
expected by Tweeter or any Subsidiary to be, incurred with respect to any such
plan by Tweeter or any Subsidiary or any Pension Affiliate. The execution,
delivery and performance by Tweeter of this Agreement and the other Lender

same shall become in arrears, all material taxes, assessments and other
governmental charges, imposed upon it and its properties, sales and activities,
or upon the income or profits therefrom, as well as the claims for labor,
materials, or supplies which if unpaid might by law result in a lien or charge

reserve therefor has been established and is maintained if and as required by
generally accepted accounting principles and (ii) no action to foreclose any
such lien has been commenced and (b) will promptly pay or cause to be paid when
due, or in conformance with customary trade terms (but not later than sixty (60)

operations. Tweeter and each Subsidiary shall cause all applicable tax returns

insurance against other hazards and risks and liability to persons and property
to the extent and in a manner reasonably satisfactory to the Lenders, and in any

compensation and with respect to group medical benefits under any medical
benefit plan. The provisions of the Security Documents relating to insurance
shall not be limited by the provisions of this Section 8.4. On request of the

<PAGE>   48
change in GAAP. Tweeter and its Subsidiaries shall not change their fiscal year

of Tweeter and its Subsidiaries with any of their officers or directors and with
Tweeter's independent accountants. Additionally, Tweeter at its own expense,
shall permit the Agent and any of the Agent's agents or representatives (a) to
conduct field exams once each year and (b) to perform inventory appraisals once
a year; provided, however that if an Event of Default exists, there shall be no

amendment with respect to the pledge of all of the capital stock of such new
Subsidiary, in form and substance reasonably satisfactory to the Agent, together
with evidence in form and substance reasonably satisfactory to the Agent that

<PAGE>   49

         Section 8.9 Covenants Relating to Canton Mortgage Financing. On or
before December 31, 1998 New England Audio directly or through a Subsidiary to
which title to the Canton Facility is conveyed (the "Real Estate Subsidiary")
shall refinance the acquisition cost of the Canton Facility through long-term
conventional mortgage financing, with recourse only to the Canton Facility
including any rental payments thereon and not to any other asset of New England
Audio, Tweeter or any Subsidiary, and on such other terms and conditions
reasonably acceptable to the Agent and shall apply the proceeds of such
financing to repay Revolving Credit Advances. At the time of such refinancing
and so long as no Default is outstanding hereunder, the Agent will release the
lien granted pursuant to the Canton Mortgage upon payment of outstanding
Revolving Credit Advances with the proceeds from such long-term conventional
mortgage financing so long as such long-term conventional mortgage financing is
entered into with a mortgagee other than the Agent; provided that (a) the
mortgagee has entered into a Subordination, Non-Disturbance and Attornment
Agreement with Tweeter and New England Audio and an agreement with the Agent
regarding waivers of liens against Collateral and granting the Agent access to
its Collateral all on terms and conditions reasonably acceptable to the Agent
and (b) the terms of the lease with Tweeter and New England Audio is on terms
and conditions reasonably approved by the Agent. In the event New England Audio
elects to secure such financing through the Real Estate Subsidiary, New England
Audio may make an Investment in the Real Estate Subsidiary by contributing the
Canton Facility to it, the Real Estate Subsidiary shall own no other assets and
conduct no other business, and no pledge of the Real Estate Subsidiary's stock
shall be required as security for the Lender Obligation. Borrowers acknowledge
and agree that Agent is under no obligation, either as Agent or as Lender, to
provide Borrowers or its Subsidiaries with long-term conventional mortgage
financing as described in Section 8.9. In the event Agent, in its sole
discretion, determines that it will provide Borrowers or its Subsidiaries with
said long-term conventional financing, such financing shall be on the terms and
conditions that Agent shall determine in its sole discretion.

                          ARTICLE 9. NEGATIVE COVENANTS

         On and after the date hereof, until all of the Lender Obligations shall
have been paid in full and the Lenders shall have no commitments, the Borrowers

accordance with the provisions of Section 8.2 hereof, (ii) judgments or awards
which have been in force for less than the applicable appeal period so long as
execution is not levied thereunder or in respect of which Tweeter or any
Subsidiary shall at the time in good faith be prosecuting an appeal or
proceedings for review in a manner reasonably satisfactory to the Lenders and in
respect of which a stay of execution shall have been obtained pending such
appeal or review and for which adequate reserves have been established in
accordance with generally accepted accounting principles and (iii) endorsements
made in connection with the deposit of items for credit or collection in the
ordinary course of business.

                  (d) Indebtedness in an amount not to exceed $1,000,000 in

any Subsidiary, and on such other terms and conditions reasonably approved by
the Agent.

                  (h) The Tweeter Trust Loans so long as the obligations of the
Borrowers thereunder are subordinated to the Lender Obligations pursuant to the
Tweeter Trust Subordination Agreement.

created or incurred or to exist any encumbrance, mortgage, pledge, lien, charge
or other security interest of any kind upon any of its property or assets of any
character, whether now owned or hereafter acquired, or transfer any of such
property or assets for the purposes of subjecting the same to the payment of
Indebtedness or performance of any other obligation in priority to payment of
its general creditors, or acquire or agree or have an option to acquire any
property or assets upon conditional sale or other title retention agreement,
device or arrangement (including Capitalized Leases) or suffer to exist for a
period of more than thirty (30) days after the same


                                       45
<PAGE>   51
shall have been incurred any Indebtedness against it which if unpaid might by
law or upon bankruptcy or insolvency, or otherwise, be given any priority
whatsoever over the claims of its general creditors, or sell, assign, pledge or
otherwise transfer for security any of its accounts, contract rights, general
intangibles, or chattel paper (as those terms are defined in the UCC) with or

include mortgages, conditional sale contracts, Capitalized Leases and all other
title retention or deferred purchase devices) to secure the purchase price of
property acquired hereafter by Tweeter or a Subsidiary, or to secure
Indebtedness incurred solely for the purpose of financing such acquisitions;
provided, however, that no such purchase money security interests shall extend
to or cover any property other than the property the purchase price of which is
secured by it, and that the principal amount of Indebtedness (whether or not
assumed) with respect to each item of property subject to such a security

forth in any particular provision of this Agreement, any consent or approval
required or permitted by this Agreement to be given by the Lenders, including
without limitation under Section 11.2, may be given, and any term of this
Agreement or of any other instrument related hereto or mentioned herein may be
amended, and the performance or observance by the Loan Parties of any term of
this Agreement may be waived (either generally or in a particular instance and
either retroactively or prospectively) with, but only with, the written consent
of the Loan Parties and the Majority Lenders; provided, however, that without
the written consent of all Lenders:

                  (a) no reduction in the interest rates on or any fees relating
to the Revolving Credit Advances shall be made;

                  (b) no extension or postponement shall be made of the stated
time of payment of the principal amount of, interest on, or fees payable to the

                  (f) no change in the provisions of this Section 11.1 shall be

         Section 11.2. Actions by Borrowers. No delay or omission on the Agent's
or the Lenders' part in exercising their rights and remedies against the Loan
Parties or any other interested party shall constitute a waiver. A breach by the
Loan Parties of their obligations under this Agreement may be waived only by a
written waiver executed by the Agent and the Lenders in accordance with Section
11.1. The Agent's and the Lenders' waiver of the Loan Parties' breach in one or
more instances shall not constitute or otherwise be an implicit waiver of
subsequent breaches. To the extent permitted by applicable law, the Loan Parties
hereby agree to waive, and do hereby absolutely and irrevocably waive (a) all
presentments, demands for performance, notices of protest and notices of
dishonor in connection with any of the Indebtedness evidenced by the Revolving
Credit Notes, (b) any requirement of diligence or promptness on the Agent's or
the Lenders' part in the enforcement of its rights under the provisions of this
Agreement or any Lender Agreement and (c) any and all notices of every kind and
description which may be required to be given by any statute or rule of law with
respect to its liability (i) under this Agreement or in respect of the
Indebtedness evidenced by the Revolving Credit Notes or any other Lender
Obligation or (ii) under any other Lender Agreement. No course of dealing
between the Loan Parties and the Agent or the Lenders shall operate as a waiver
of any of the Agent's or the Lenders' rights under this Agreement or any Lender
Agreement or with respect to any of the Lender Obligations. This Agreement shall
be amended only by a written instrument executed by the Agent and the Lenders in
accordance with Section 11.1 making explicit reference to this Agreement. The
Agent's and the Lenders' rights and remedies under this Agreement and under all
subsequent agreements between the Agent, the Lenders and the Loan Parties shall
be cumulative and any rights and remedies expressly set forth herein shall be in
addition to, and not in limitation of, any other rights and remedies which may
be applicable to the Agent and the Lenders in law or at equity.


                       ARTICLE 12. SUCCESSORS AND ASSIGNS

         Section 12.1. General. This Agreement shall be binding upon and shall
inure to the benefit of the parties hereto and their respective successors
(which shall include in the case of the Agent or any Lender any entity resulting
from a merger or consolidation) and assigns, except that (a) the Loan Parties
may not assign their rights or obligations under this Agreement and (b) each
Lender may assign its rights in this Agreement only as set forth below in this
Article 12.


                                       53
<PAGE>   59
         Section 12.2. Assignments.

                  (a) Assignments. In compliance with applicable laws with
respect to such assignment and with the consent of Tweeter (provided that if
there shall exist a Default, the consent of Tweeter shall not be required for
any such assignment) and the Agent (which consents in all cases shall not be
unreasonably withheld), a Lender may assign to one or more financial
institutions (each a "Successor Lender") a proportionate part of its rights and
obligations in connection with this Agreement, its Revolving Credit Note and the
related Lender Agreements and each such Successor Lender shall assume such
rights and obligations pursuant to an Assignment and Acceptance Agreement
("Assignment and Acceptance Agreement") duly executed by such Successor Lender
and such assigning Lender and acknowledged and consented to by the Loan Parties
and the Agent, substantially in the form of Exhibit N attached hereto. Any
assignment under this Section 12.2(a) shall be in a minimum amount of $5,000,000
with respect to the Commitment Percentage of the Maximum Revolving Credit
Amount. In connection with any assignment under this Section 12.2(a) there shall
be paid to the Agent by the assigning Lender or the Successor Lender an
administrative processing fee in the amount of $2,500. The Lenders recognize
that the proposed assignment hereunder to a foreign bank that would trigger any
tax withholding requirement pertaining to payments to be made to such foreign
bank shall constitute a reasonable ground for New England Audio or its
Subsidiaries to withhold consent to the proposed assignment pursuant to this
Section 12.2.

                  (b) Assignment Procedures. In the event of an assignment in
accordance with Section 12.2(a), upon execution and delivery of such an
assignment at least five (5) Business Days prior to the proposed assignment
date, and payment by such Successor Lender to the assigning Lender of an amount
equal to the purchase price agreed between such assigning Lender and such
Successor Lender, such Successor Lender shall become party to this Agreement as
a signatory hereto and shall have all the rights and obligations of a Lender
under this Agreement and the other Lender Agreements with an interest therein as
set forth in such assignment, and such assignor making such assignment shall be
released from its obligations hereunder to a corresponding extent, and no
further consent or action by any party shall be required. Upon the consummation
of any such assignment, the assigning Lender, the Successor Lender and the
Borrowers shall make appropriate arrangements so that, if required, a new
Revolving Credit Note is issued to the Successor Lender and a replacement
Revolving Credit Note is issued to the assigning Lender in principal amounts
reflecting their respective revised interests.

                  (c) Register. The Agent shall maintain a register (the
"Register") for the recordation of (i) the names and addresses of all Successor
Lenders that enter into Assignment and Acceptance Agreements, (ii) the interests
of each Lender and (iii) the amounts of the Revolving Credit Advances owing to
each Lender from time to time. The entries in the Register shall, if made in
good faith, be conclusive, in the absence of manifest error, and the Loan
Parties, the Agent and the Lenders may treat each Person whose name is
registered therein for all purposes as a party to this Agreement. The Register
shall be available for


                                       54
<PAGE>   60
inspection by the Loan Parties or any Lender at any reasonable time and from
time to time upon reasonable prior notice.

                  (d) Further Assurances. The Loan Parties shall sign such
documents and take such other actions from time to time reasonably requested by
the Agent or a Lender to enable any Successor Lender to share in the benefits
and rights created by the Lender Agreements.

                  (e) Assignments to Federal Reserve Bank. Any Lender at any
time may assign all or any portion of its rights under this Agreement and its
Revolving Credit Note to a Federal Reserve Bank. No such assignment shall
release the transferor Lender from its obligations hereunder.

         Section 12.3. Participations. Any Lender may, without the consent of
the Loan Parties or the Agent, at any time grant or offer to grant to one or
more financial institutions ("Credit Participants") participating interests in
such Lender's rights and obligations in this Agreement, its Revolving Credit
Note and the related Lender Agreements, and each such Credit Participant shall
acquire such participation subject to the terms set forth below.

                  (a) Amount. Each such participation shall be in a minimum
amount of at least $2,500,000.

                  (b) Procedure. Each Lender granting such participation shall
comply with all applicable laws with respect to such transfer and shall remain
responsible for the performance of its obligations hereunder and under the other
Lender Agreements and shall retain the sole right and responsibility to exercise
its rights and to enforce the obligations of the Borrowers hereunder and under
the other Lender Agreements, including the right to consent to any amendment,
modification or waiver of any provision of any Lender Agreement, except for
those matters referred to in Section 11.1 which require the consent of all
Lenders and which may also require the consent of each Credit Participant.

                  (c) Dealing with Lenders. The Loan Parties shall continue to
deal solely and directly with the Lenders in connection with their rights and
obligations under this Agreement and the other Lender Agreements.

                  (d) Rights of Credit Participants. The Loan Parties agree that
each Credit Participant shall, to the extent provided in its participation
instrument, be entitled to the benefits of Sections 2.7, 2.8, 2.9, 2.11, 2.12
and 14.5, and the set-off rights in Section 10.2 with respect to its
participating interest; provided, however, that no Credit Participant shall be

                              ARTICLE 13. THE AGENT

         Section 13.1. Authorization and Action. Each Lender hereby appoints and
authorizes the Agent to take such action on its behalf and to exercise such
powers under this Agreement and the other Lender Agreements as are delegated to
the Agent by the terms hereof and thereof, together with such powers as are
reasonably incidental thereto. As to any matters not expressly provided for by
this Agreement and the other Lender Agreements (including, without limitation,
enforcement or collection of the Revolving Credit Notes), the Agent shall not be
required to exercise any discretion or take any action, but shall be required to
act or to refrain from acting (and shall be fully protected in so acting or
refraining from acting) upon the instructions of the Majority Lenders, and such
instructions shall be binding upon all Lenders; provided, however, that the
Agent shall not be required to take any action which exposes the Agent to
liability or which is contrary to this Agreement or the other Lender Agreements
or applicable law. Subject to the foregoing provisions and to the other
provisions of this Article 13, the Agent shall, on behalf of the Lenders: (a)
execute any documents on behalf of the Lenders providing collateral for or
guarantees of the Lender Obligations; (b) hold and apply any collateral for the
Lender Obligations, and the proceeds thereof, at any time received by it, in
accordance with the provisions of this Agreement and the other Lender
Agreements; (c) exercise any and all rights, powers and remedies of the Lenders
under this Agreement or any of the other Lender Agreements, including the giving
of any consent or waiver or the entering into of any amendment, subject to the
provisions of Section 11.1; (d) at the direction of the Lenders, execute,
deliver and file UCC financing statements, mortgages, deeds of trust, lease
assignments and such other agreements in respect of any collateral for the
Lender Obligations, and possess instruments included in the collateral on behalf
of the Lenders; and (e) in the event of acceleration of the Borrowers'
Indebtedness hereunder, act at the direction of the Majority Lenders to exercise
the rights of the Lenders hereunder and under the other Lender Agreements.

         Section 13.2. Agent's Reliance, Etc. Neither the Agent nor any of its
directors, officers, agents or employees shall be liable to the Lenders for any
action taken or omitted to be taken by it or them under or in connection with
this Agreement or the other Lender Agreements, except for its or their own gross
negligence or willful misconduct. Without limitation of the generality of the
foregoing, the Agent: (a) may treat the payee of any Revolving Credit Note as
the holder thereof until the Agent receives written notice of the assignment or
transfer thereof signed by such payee and in form required under Article 12
hereof; (b) may consult with legal counsel, independent public accountants and
other experts selected by it and shall not be liable for any action taken or
omitted to be taken in good faith by it in accordance with the advice of such
counsel, accountants or experts; (c) makes no warranty or representations to any
Lender and shall not be responsible to any Lender for any statements, warranties
or representations made in or in connection with this Agreement or the other
Lender Agreements; (d) shall not have any duty to ascertain or to inquire as to
the performance or observance of any of the terms, covenants or conditions of
this Agreement or the other Lender Agreements on the part of the Loan Parties or
any other Person or to inspect the property


                                       56
<PAGE>   62
(including the books and records) of the Loan Parties or any other Person; (e)
shall not be responsible to any Lender for the due execution, legality,
validity, enforceability, genuineness, sufficiency or value of this Agreement or
the other Lender Agreements or any other instrument or document furnished
pursuant hereto or thereto; and (f) shall incur no liability under or in respect
of this Agreement or the other Lender Agreements by acting upon any notice,
consent, certificate or other instrument or writing (which may be by telecopy or
telegram) believed by the Agent to be genuine and signed or sent by the proper
party or parties.

         Section 13.3. Agent as a Lender. With respect to its Revolving Credit
Commitment Percentage of the Revolving Credit Advances hereunder, BankBoston,
N.A. shall have the same rights and powers under this Agreement and the other
Lender Agreements as any other Lender and may exercise the same as though it
were not the Agent; and the term "Lender" or "Lender(s)" shall, unless otherwise
expressly indicated, include BankBoston, N.A. in its individual capacity.
BankBoston, N.A. and its affiliates may lend money to, and generally engage in
any kind of business with, the Loan Parties, any of the Loan Parties' Affiliates
and any Person who may do business with or own securities of the Loan Parties or
any such Affiliate of the Loan Parties, all as if BankBoston, N.A. were not the
Agent and without any duty to account therefor to the Lenders.

         Section 13.4. Lender Credit Decision. Each Lender acknowledges that it
has, independently and without reliance upon the Agent or any other Lender and
based on the financial statements referred to in Section 5.9 and such other
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the Agent or
any other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement.

         Section 13.5. Indemnification of Agent. Each Lender agrees to indemnify
the Agent and its directors, officers, employees and agents (to the extent that
the Agent is not reimbursed by the Loan Parties), ratably according to each
Lender's Commitment Percentage, 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 the Agent or its directors, officers,
employees or agents in any way relating to or arising out of this Agreement or
any other Lender Agreement or any action taken or omitted by the Agent in such
capacity under this Agreement; provided that no Lender shall be liable for any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from the Agent's
gross negligence or wilful misconduct. Without limitation of the foregoing, each
Lender agrees to reimburse the Agent promptly upon demand for its ratable share
of any out-of-pocket expenses (including counsel fees) incurred by the Agent in
connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or


                                       57
<PAGE>   63
responsibilities under, this Agreement and each other Lender Agreement, to the
extent that the Agent is not reimbursed for such expenses by the Loan Parties.

         Section 13.6. Successor Agent. Except as provided below, the Agent may
resign at any time by giving written notice thereof to the Lenders and the
Borrower. Upon any such resignation, the Lenders shall have the right to appoint
a successor Agent which shall be reasonably acceptable to Tweeter. If no
successor Agent shall have been so appointed by the Lenders (other than the
resigning Agent), and shall have accepted such appointment, within thirty (30)
days after the retiring Agent's giving notice of resignation, then the retiring
Agent may, on behalf of the Lenders, appoint a successor Agent, which shall be a
commercial bank or financial institution organized under the laws of the United
States of America or of any state thereof and having a combined capital and
surplus of at least $50,000,000 and which shall be reasonably acceptable to
Tweeter. Upon the acceptance of any appointment as Agent hereunder by a
successor Agent, such successor Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring Agent,
and the retiring Agent shall be discharged from its duties and obligations under
this Agreement and the other Lender Agreements. After any retiring Agent's
resignation hereunder as Agent, the provisions of this Article 13 shall inure to
its benefit as to any actions taken or omitted to be taken by it while it was
Agent under this Agreement and the other Lender Agreements.

         Section 13.7. Amendment of Article 13. The Loan Parties hereby agree
that the foregoing provisions of this Article 13 constitute an agreement among
the Agent and the Lenders (and the Agent and the Lenders acknowledge that except
for the provisions of Section 13.6, the Loan Parties are not parties to or bound
by such foregoing provisions) and that any and all of the provisions of this
Article 13 may be amended at any time by the Lenders without the consent or
approval of, or notice to, the Loan Parties (other than the requirement of
notice to the Tweeter of the resignation of the Agent and the appointment of a
successor Agent).

         Section 14.5. Expenses and Indemnification.

                  (a) The Loan Parties, jointly and severally, agree to pay, on
demand, all of the Agent's reasonable expenses in preparing, executing,
delivering and administering this Agreement, the Lender Agreements and all
related instruments and documents, including, without limitation, the reasonable
fees and out-of-pocket expenses of the Agent's special counsel, Goodwin, Procter
& Hoar LLP, and the Agent's expenses in connection with periodic audits, field
exams and inventory appraisals of the Loan Parties. The Loan Parties, jointly
and severally, also agree to pay, on demand, all reasonable out-of-pocket
expenses incurred by the Agent and the Lenders, including, without limitation,
reasonable legal and accounting fees, in connection with the collection of
amounts due hereunder and under all other Lender Agreements upon the occurrence
of an Event of Default hereunder, the revision, protection or enforcement of any
of the Agent's or the Lenders' rights against the Loan Parties under this
Agreement, the Revolving Credit Notes and all other Lender Agreements and the
administration of special problems that may arise under this Agreement or any
other Lender Agreement. The Loan Parties also agree to pay all stamp and other
taxes in connection with the execution and delivery of this Agreement and
related instruments and documents.

                  (b) Without limitation of any other obligation or liability of
the Loan Parties or right or remedy of the Agent or the Lenders contained
herein, the Loan Parties hereby covenant and agree, jointly and severally, to
indemnify and hold the Agent, the Lenders, and the directors, officers,
subsidiaries, shareholders, agents, affiliates and Persons controlling the Agent
and the Lenders, harmless from and against any and all damages, losses,
settlement payments, obligations, liabilities, claims, including, without
limitation, claims for finder's or broker's fees, actions or causes of action,
and reasonable costs and expenses incurred, suffered, sustained or required to
be paid by any such indemnified party in each case by reason of or resulting
from any claim relating to the transactions contemplated hereby, other than any
such claims which are determined by a final, non-appealable judgment or order of
a court of competent jurisdiction to be the result of the gross negligence or
willful misconduct of such indemnified party. Promptly upon receipt by any
indemnified party hereunder of notice of the commencement of any action against
such indemnified party for which a claim is to be made against the Loan Parties
hereunder, such indemnified party shall notify the Loan Parties in writing of
the commencement thereof, although the failure to provide such notice shall not
affect the indemnification rights of any such indemnified party hereunder unless
and only to the extent the Loan Parties demonstrate to the reasonable
satisfaction of such party that such failure to provide notice prejudiced the
Loan Parties in their defense of such claim. The Loan Parties shall have the
right, at their option upon notice to the indemnified parties, to defend any
such matter at their own expense and with their own counsel, except as provided
below, which counsel must be reasonably acceptable to the indemnified parties.
The indemnified party shall cooperate with the Loan Parties in the defense of
such matter. The indemnified party shall have the right to employ separate
counsel and to participate in the defense of such matter at its own expense. In
the event that (a) the employment of separate counsel by an indemnified party
has been authorized in writing by the Loan Parties, (b) the Loan Parties have
failed to assume the defense of such matter within fifteen (15) days of notice
thereof from the


                                       60
<PAGE>   66
indemnified party, or (c) the named parties to any such action (including
impleaded parties) include any indemnified party who has been advised by counsel
that there may be one or more legal defenses available to it or prospective
bases for liability against it, which are different from those available to or
against the Loan Parties, then the Loan Parties shall not have the right to
assume the defense of such matter with respect to such indemnified party. The
Loan Parties shall not compromise or settle any such matter against an
indemnified party without the written consent of the indemnified party, which
consent may not be unreasonably withheld or delayed.

         Section 14.6. Confidentiality. The Agent and the Lenders agree to use,
and to cause their officers, directors and employees to use, commercially
reasonable efforts to keep in confidence all financial data and other
information relative to the affairs of Tweeter and its Subsidiaries heretofore
furnished or which may hereafter be furnished to them pursuant to the provisions
of this Agreement; provided, however, that this Section 14.6 shall not be
applicable to information otherwise disseminated to the public by Tweeter or any
of its Affiliates; and provided further, that such obligation of the Agent and
the Lenders shall be subject to the Agent's or the Lenders', as the case may be,
(a) obligation to disclose such information pursuant to a request or order under
applicable laws and regulations or pursuant to a subpoena or other legal
process, (b) right to disclose any such information to bank examiners,
affiliates, auditors, accountants and counsel who agree to keep such information
confidential and (c) right to disclose any such information (i) in connection
with the transactions set forth herein including assignments or the sale of
participation interests pursuant to Article 12, so long as such potential
assignees or participants shall agree in writing to be bound by the terms of
this Section 14.6 or (ii) in connection with any litigation or dispute involving
the Agent or any transfer or other disposition by the Agent or the Lenders, as
the case may be, of any of the Lender Obligations; provided that information
disclosed pursuant to this provision shall be so disclosed subject to such
procedures as are reasonably calculated to maintain the confidentiality thereof.

         Section 14.7. Reliance on Representations and Actions of Tweeter. The
Loan Parties hereby appoint New England Audio as the Loan Parties' agent to
execute, deliver and perform, on behalf of the Loan Parties, any and all
notices, certificates, documents and actions to be executed, delivered or
performed hereunder or under any of the other Lender Agreements, and the Loan
Parties hereby agree that the Agent and the Lenders may rely upon any
representation, warranty, certificate, notice, document or telephone request
which purports to be executed or made or which the Agent or the Lenders in good
faith believe to have been executed or made by New England Audio or Tweeter on
its behalf or any of their executive officers, and the Loan Parties hereby
further, jointly and severally, agree to indemnify and hold the Agent and the
Lenders harmless for any action, including the making of Revolving Credit
Advances hereunder, and any loss or expense, taken or incurred by any of them as
a result of their good faith reliance upon any such representation, warranty,
certificate, notice, document or telephone request.

Borrowers hereunder, under the Revolving Credit Notes and under all other Lender
Agreements shall be joint and several obligations of the Borrowers, and all
obligations of the Guarantors hereunder and under all other Lender Agreements
shall be joint and several obligations of the Guarantors.

         Section 14.9. WAIVER OF JURY TRIAL. THE AGENT, THE LENDERS AND THE LOAN
PARTIES AGREE THAT NONE OF THEM NOR ANY ASSIGNEE OR SUCCESSOR SHALL (A) SEEK A
JURY TRIAL IN ANY LAWSUIT, PROCEEDING, COUNTERCLAIM OR ANY OTHER ACTION BASED
UPON OR ARISING OUT OF, THIS AGREEMENT, THE REVOLVING CREDIT NOTES, ANY LENDER
AGREEMENT, ANY RELATED INSTRUMENTS, ANY COLLATERAL OR THE DEALINGS OR THE
RELATIONSHIP BETWEEN OR AMONG ANY OF THEM OR (B) SEEK TO CONSOLIDATE ANY SUCH
ACTION WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT BE OR HAS NOT BEEN
WAIVED. THE PROVISIONS OF THIS PARAGRAPH HAVE BEEN FULLY DISCUSSED BY EACH OF
THE AGENT, THE LENDERS AND THE LOAN PARTIES WITH THEIR RESPECTIVE COUNSEL, AND
THESE PROVISIONS SHALL BE SUBJECT TO NO EXCEPTIONS. NONE OF THE AGENT, THE
LENDERS OR THE LOAN PARTIES HAS AGREED WITH OR REPRESENTED TO ANY OTHER PARTY
THAT THE PROVISIONS OF THIS PARAGRAPH WILL NOT BE FULLY ENFORCED IN ALL
INSTANCES.

            (d) None of the Pledged Shares has been issued or transferred in
violation of the securities registration, securities disclosure or similar laws
of any jurisdiction to which such issuance or transfer may be subject.

            (e) The authorized Stock of each of the issuers listed on Schedule I
hereto consists of the number of shares of Stock, with the number of shares
issued and outstanding, that are described on Schedule I hereto. As of the date
hereof, there are no existing options, warrants, calls or commitments of any
character whatsoever relating to any Stock of any of such issuers.

            (f) No consent, approval, authorization or other order of any Person
and no consent, authorization, approval, or other action by, and no notice to or
filing with, any governmental authority or regulatory body is required either
(i) for the pledge of the Pledged Collateral pursuant to this Agreement or for
the execution, delivery or performance of this Agreement by the Pledgor or (ii)
for the exercise by the Agent of the voting or other rights


                                        3
<PAGE>   84
provided for in this Agreement or the remedies in respect of the Pledged
Collateral pursuant to this Agreement including any disposition thereof, except
as may be required in connection with such disposition by laws affecting the
offering and sale of securities generally.

            (g) The pledge, assignment and delivery of the Pledged Collateral
pursuant to this Agreement will create a valid first priority Lien on and a
first priority perfected security interest in the Pledged Collateral, and the
proceeds thereof, securing the payment of the Secured Obligations.

            (h) This Agreement has been duly authorized, executed and delivered
by the Pledgor and constitutes a legal, valid and binding obligation of the
Pledgor enforceable in accordance with its terms, except as limited by
bankruptcy, insolvency, reorganization, moratorium or other laws affecting the
enforcement of creditors' rights generally, and except as the remedy of specific
performance or injunctive relief is subject to the discretion of the court
before which any proceeding therefor may be brought.

            (i) The Pledged Shares constitute one hundred percent (100%) of the
issued and outstanding shares of Stock of the issuers thereof.

            (j) The Subsidiaries listed on Schedule III hereto are the only
Subsidiaries of the Pledgor.

      The representations and warranties set forth in this Section 5 shall
survive the execution and delivery of this Agreement.

      Section 6. Covenants. The Pledgor covenants and agrees that until the
Termination Date:

            (a) Without the prior written consent of the Agent, the Pledgor will
not sell, assign, transfer, pledge, grant a Lien with respect to or otherwise
encumber any of its rights in or to the Pledged Collateral or any unpaid
dividends or other distributions or payments with respect thereto except as
otherwise permitted by the Credit Agreement.

            (b) The Pledgor will, at its expense, promptly execute, acknowledge
and deliver all such instruments and take all such action as the Agent from time
to time may reasonably request in order to ensure to the Agent the benefits of
the Liens in and to the Pledged Collateral intended to be created by this
Agreement.

            (c) The Pledgor will defend the title to the Pledged Collateral and
the Liens of the Agent thereon against the claim of any other Person and will
maintain and preserve such Liens until the Termination Date.

            (d) The Pledgor will, upon obtaining any additional shares of any
Subsidiaries other than the Real Estate Subsidiary, if any, which shares are not
already Pledged Collateral,


                                        4
<PAGE>   85
promptly (and in any event within three (3) Business Days) deliver to the Agent
a Pledge Amendment, duly executed by the Pledgor, in substantially the form of
Schedule II hereto (a "Pledge Amendment"), in respect of the additional Pledged
Shares which are to be pledged pursuant to this Agreement. The Pledgor hereby
authorizes the Agent to attach each such Pledge Amendment to this Agreement and
agrees that all Pledged Shares listed on any Pledge Amendment delivered to the
Agent shall for all purposes hereunder be considered Pledged Collateral.

      Section 7. Pledgor's Rights. As long as no Default or Event of Default
shall have occurred and be continuing:

            (a) The Pledgor shall have the right, from time to time, to vote and
give consents with respect to the Pledged Collateral or any part thereof for all
purposes not inconsistent with the provisions of this Agreement, the Credit
Agreement and any other Lender Agreement; provided, however, that no vote shall
be cast, and no consent shall be given or action taken, which would have the
effect of impairing the position or interest of the Agent in respect of the
Pledged Collateral or which would authorize or effect (except as and to the
extent expressly permitted by the Credit Agreement) (i) the dissolution or
liquidation, in whole or in part, of any of the Subsidiaries, (ii) the
consolidation or merger of any of the Subsidiaries with any other Person, (iii)
the sale, disposition or encumbrance of all or substantially all of the assets
of any of the Subsidiaries, (iv) any change in the authorized number of shares,
the stated capital or the authorized share capital of any of the Subsidiaries or
the issuance of any additional shares of its Stock, or (v) the alteration of the
voting rights with respect to the Stock of any of the Subsidiaries.

            (b) (i) the Pledgor shall be entitled, from time to time, to collect
      and receive for its own use all cash dividends paid in respect of the
      Pledged Shares to the extent not in violation of the Credit Agreement
      other than any and all (A) dividends paid or payable other than in cash in
      respect of, and instruments and other property received, receivable or
      otherwise distributed in respect of, or in exchange for, any Pledged
      Collateral, (B) dividends and other distributions paid or payable in cash
      in respect of any Pledged Collateral in connection with a partial or total
      liquidation or dissolution and (C) cash paid, payable or otherwise
      distributed in redemption of, or in exchange for, any Pledged Collateral;
      provided, however, that until actually paid all rights to such dividends
      shall remain subject to the Lien created by this Agreement; and

                (ii) all dividends (other than such cash dividends as are
      permitted to be paid to the Pledgor in accordance with clause (i) above)
      and all other distributions in respect of any of the Pledged Shares,
      whenever paid or made, shall be delivered to the Agent to hold as Pledged
      Collateral and shall, if received by the Pledgor, be received in trust for
      the benefit of the Agent, be segregated from the other property or funds
      of the Pledgor, and be forthwith delivered to the Agent as Pledged
      Collateral in the same form as so received (with any necessary
      endorsement).

      Section 8. Defaults and Remedies.

            (a) Upon the occurrence and during the continuance of an Event of
Default (provided that such Event of Default is not waived in accordance with
the terms of the Credit Agreement), the Agent (personally or through an agent)
is hereby authorized and empowered, to transfer and register in its name or in
the name of its nominee the whole or any part of the Pledged Collateral, to
exercise the voting rights with respect thereto, to collect and receive all cash
dividends and other distributions made thereon, to sell in one or more sales
after ten (10) days' notice of the time and place of any public sale or of the
time after which a private sale is to take place (which notice the Pledgor
agrees is commercially reasonable), but without any previous notice or
advertisement, the whole or any part of the Pledged Collateral and to otherwise
act and to exercise any and all rights with respect to the Pledged Collateral as
though the Agent was the outright owner thereof, the Pledgor hereby irrevocably
constituting and appointing the Agent as the proxy and attorney-in-fact of the
Pledgor, with full power of substitution to do so; provided, however, that the
Agent shall not have any duty to exercise any such right or to preserve the same
and shall not be liable for any failure to do so or for any delay in doing so.
Any sale shall be made at a public or private sale at the Agent's place of
business, or at any public building in the City of Boston, Massachusetts or
elsewhere to be named in the notice of sale, either for cash or upon credit or
for future delivery at such price as the Agent may deem fair, and the Agent may
be the purchaser of the whole or any part of the Pledged Collateral so sold and
hold the same thereafter in its own right free from any claim of the Pledgor or
any right of redemption. Each sale shall be made to the highest bidder, but the
Agent reserves the right to reject any and all bids at such sale which, in its
discretion, it shall reasonably deem inadequate. Demands of performance, except
as otherwise herein specifically provided for, notices of sale, advertisements
and the presence of property at sale are hereby waived and any sale hereunder
may be conducted by an auctioneer or any officer or agent of the Agent.

            (b) If, at the original time or times appointed for the sale of the
whole or any part of the Pledged Collateral, the highest bid, if there be but
one sale, shall be inadequate to discharge in full all the Secured Obligations,
or if the Pledged Collateral be offered for sale in lots, if at any of such
sales, the highest bid for the lot offered for sale would indicate to the Agent,
in its reasonable discretion, the unlikelihood of the proceeds of the sales of
the whole of the Pledged Collateral being sufficient to discharge all the
Secured Obligations, the Agent may, on one or more occasions and in its
reasonable discretion, postpone any of said sales by public announcement at the
time of sale or the time of previous postponement of sale, and no other notice
of such postponement or postponements of sale need be given, any other notice
being hereby waived; provided, however, that any sale or sales made after such
postponement shall be after ten (10) days' notice to the Pledgor.

            (c) In the event of any sales hereunder, the Agent shall, after
deducting all reasonable costs or expenses of every kind (including reasonable
attorneys' fees and disbursements) for care, safekeeping, collection, sale,
delivery or otherwise, apply the residue of the proceeds of the sales to the
payment or reduction, either in whole or in part, of the


                                        6
<PAGE>   87
Secured Obligations in accordance with the agreements and instruments governing
and evidencing the Secured Obligations, returning the surplus, if any, to the
Pledgor.

            (d) If, at any time when the Agent in its reasonable discretion
determines, following the occurrence and during the continuance, of an Event of
Default, that, in connection with any actual or contemplated exercise of its
rights (when permitted under this Section 8) to sell the whole or any part of
the Pledged Collateral hereunder, it is necessary or advisable to effect a
public registration of all or part of the Pledged Collateral pursuant to the
Securities Act of 1933, as amended (or any similar statute then in effect) (the
"Act"), the Pledgor shall, in an expeditious manner, cause each of its
Subsidiaries other than the Real Estate Subsidiary, if any, to:

                  (i)   prepare and file with the Securities and Exchange
      Commission (the "Commission") a registration statement with respect to the
      Pledged Collateral and use its best efforts to cause such registration
      statement to become and remain effective;

                  (ii)  prepare and file with the Commission such amendments and
      supplements to such registration statement and the prospectus used in
      connection therewith as may be necessary to keep such registration
      statement effective and to comply with the provisions of the Act with
      respect to the sale or other disposition of the Pledged Collateral covered
      by such registration statement whenever the Agent shall desire to sell or
      otherwise dispose of the Pledged Collateral;

                  (iii) furnish to the Agent such numbers of copies of a
      prospectus and a preliminary prospectus, in conformity with the
      requirements of the Act, and such other documents as the Agent may
      reasonably request in order to facilitate the public sale or other
      disposition of the Pledged Collateral by the Agent;

                  (iv)  use its best efforts to register or qualify the Pledged
      Collateral covered by such registration statement under such other
      securities or blue sky laws of such jurisdictions within the United States
      as the Agent shall reasonably request, and do such other reasonable acts
      and things as may be required of it to enable the Agent to consummate the
      public sale or other disposition in such jurisdictions of the Pledged
      Collateral by the Agent;

                  (v)   use its best efforts to furnish, at the reasonable
      request of the Agent, on the date that shares of the Pledged Collateral
      are delivered to the underwriters for sale pursuant to such registration
      or, if the security is not being sold through underwriters, on the date
      that the registration statement with respect to such shares of the Pledged
      Collateral becomes effective, (A) an opinion, dated such date, of the
      outside counsel representing such registrant for the purposes of such
      registration, addressed to the underwriters, if any, and in the event the
      Pledged Collateral is not being sold through underwriters, then to the
      Agent, stating that such registration statement has become effective under
      the Act and that (1) to the best knowledge of such


                                        7
<PAGE>   88
      counsel, no stop order suspending the effectiveness thereof has been
      issued and no proceedings for that purpose have been instituted or are
      pending or threatened under the Act, (2) the registration statement, the
      related prospectus, and each amendment or supplement thereto, comply as to
      form in all material respects with the requirements of the Act and the
      applicable rules and regulations of the Commission thereunder (except that
      such counsel need express no opinion as to financial statements or other
      financial or statistical data contained therein), (3) such counsel has no
      reason to believe that either the registration statement or the
      prospectus, or any amendment or supplement thereto, contains any untrue
      statement of a material fact or omits a material fact required to be
      stated therein or necessary to make the statements therein not misleading,
      (4) the descriptions in the registration statement or the prospectus, or
      any amendment or supplement thereto, of all legal matters and contracts
      and other legal documents or instruments are accurate in all material
      respects and fairly present the information required to be shown and (5)
      such counsel does not know of any legal or governmental proceedings,
      pending or threatened, required to be described in the registration
      statement or prospectus, or any amendment or supplement thereto, or to be
      filed as exhibits to the registration statement which are not described
      and filed or incorporated by reference as required; and (B) a letter,
      dated such date, from the independent certified public accountants of such
      registrant, addressed to the underwriters, if any, and in the event the
      Pledged Collateral is not being sold through underwriters, then to the
      Agent, stating that they are independent certified public accountants
      within the meaning of the Act and that, in the opinion of such
      accountants, the financial statements and other financial data of such
      registrant included in the registration statement or the prospectus, or
      any amendment or supplement thereto, comply as to form in all material
      respects with the applicable accounting requirements of the Act. The
      opinion of counsel referred to above shall additionally cover such other
      legal matters with respect to the registration in respect of which such
      opinion is being given as the Agent may reasonably request. The letter
      referred to above from the independent certified public accountants shall
      additionally cover such other financial matters (including information as
      to the period ending not more than five (5) Business Days prior to the
      date of such letter) with respect to the registration in respect of which
      such letter is being given as the Agent may reasonably request; and

                  (vi) otherwise use its best efforts to comply with all
      applicable rules and regulations of the Commission, and not later than 18
      months after the effective date of the registration statement, make
      available to the Agent an earnings statement (which need not be audited)
      covering a period of at least 12 months beginning the first full month
      after the effective date of such registration statement which earnings
      statement shall satisfy the provisions of Rule 158 promulgated under the
      Act.

            (e) All expenses incurred in complying with Section 8(d) hereof,
including, without limitation, all registration and filing fees (including all
expenses incident to filing with the National Association of Securities Dealers,
Inc.), printing expenses, fees and disbursements of counsel for the registrant,
the reasonable fees and expenses of counsel for the Agent,


                                        8
<PAGE>   89
expenses of the independent certified public accountants (including any special
audits incident to or required by any such registration) and expenses of
complying with the securities or blue sky laws or any jurisdictions, shall be
paid by the Pledgor.

            (f) If, at any time when the Agent shall determine to exercise its
rights to sell the whole or any part of the Pledged Collateral hereunder, such
Pledged Collateral or the part thereof to be sold shall not, for any reason
whatsoever, be effectively registered under the Act, the Agent may, in its
discretion (subject only to applicable requirements of law), sell such Pledged
Collateral or part thereof by private sale in such manner and under such
circumstances as the Agent may deem necessary or advisable, but subject to the
other requirements of this Section 8, and shall not be required to effect such
registration or to cause the same to be effected. Without limiting the
generality of the foregoing, in any such event the Agent in its discretion (i)
may, in accordance with applicable securities laws, proceed to make such private
sale notwithstanding that a registration statement for the purpose of
registering such Pledged Collateral or part thereof could be or shall have been
filed under the Act (or similar statute), (ii) may approach and negotiate with a
single possible purchaser to effect such sale and (iii) may restrict such sale
to a purchaser who will represent and agree that such purchaser is purchasing
for its own account, for investment and not with a view to the distribution or
sale of such Pledged Collateral or part thereof. In addition to a private sale
as provided above in this Section 8, if any of the Pledged Collateral shall not
be freely distributable to the public without registration under the Act (or
similar statute) at the time of any proposed sale pursuant to this Section 8,
then the Agent shall not be required to effect such registration or cause the
same to be effected but, in its discretion (subject only to applicable
requirements of law), may require that any sale hereunder (including a sale at
auction) be conducted subject to restrictions (A) as to the financial
sophistication and ability of any Person permitted to bid or purchase at any
such sale, (B) as to the content of legends to be placed upon any certificates
representing the Pledged Collateral sold in such sale, including restrictions on
future transfer thereof, (C) as to the representations required to be made by
each Person bidding or purchasing at such sale relating to that Person's access
to financial information about the Pledgor and such Person's intentions as to
the holding of the Pledged Collateral so sold for investment, for its own
account, and not with a view of the distribution thereof and (D) as to such
other matters as the Agent may, in its discretion, deem necessary or appropriate
in order that such sale (notwithstanding any failure so to register) may be
effected in compliance with the Uniform Commercial Code and other laws affecting
the enforcement of creditors' rights and the Act and all applicable state
securities laws.

            (g) The Pledgor acknowledges that notwithstanding the legal
availability of a private sale or a sale subject to the restrictions described
above in paragraph (f), the Agent may, in its discretion, elect to register any
or all the Pledged Collateral under the Act (or any applicable state securities
law) in accordance with its rights hereunder. The Pledgor, however, recognizes
that the Agent may be unable to effect a public sale of any or all the Pledged
Collateral and may be compelled to resort to one or more private sales thereof.
The Pledgor also acknowledges any such private sale (conducted in a commercially
reasonable manner for private sales) may result in prices and other terms less
favorable to the seller than if such sale


                                        9
<PAGE>   90
were a public sale and, notwithstanding such circumstances, agrees that any such
private sale shall be deemed to have been made in a commercially reasonable
manner. The Agent shall be under no obligation to delay a sale of any of the
Pledged Collateral for the period of time necessary to permit the registrant to
register such securities for public sale under the Act, or under applicable
state securities laws, even if the Pledgor or issuer of the Pledged Collateral
would agree to do so.

            (h) The Pledgor agrees that following the occurrence an Event of
Default, it will not at any time plead, claim or take the benefit of any
appraisal, valuation, stay, extension, moratorium or redemption law now or
hereafter in force in order to prevent or delay the enforcement of this
Agreement, or the absolute sale of the whole or any part of the Pledged
Collateral or the possession thereof by any purchaser at any sale hereunder in
accordance with the terms hereof, and the Pledgor waives the benefit of all such
laws to the extent it lawfully may do so. The Pledgor agrees that it will not
interfere with any right, power and remedy of the Agent provided for in this
Agreement or now or hereafter existing at law or in equity or by statute or
otherwise, or the exercise or beginning of the exercise by the Agent of any one
or more of such rights, powers, or remedies. No failure or delay on the part of
the Agent to exercise any such right, power or remedy and no notice or demand
which may be given to or made upon the Pledgor by the Agent with respect to any
such remedies shall operate as a waiver thereof, or limit or impair the Agent's
right to take any action or to exercise any power or remedy hereunder, without
notice or demand, or prejudice its rights as against the Pledgor in any respect.

            (i) The Pledgor further agrees that a breach of any of the covenants
contained in this Section 8 will cause irreparable injury to the Agent, that the
Agent has no adequate remedy at law in respect of such breach and, as a
consequence, agrees that each and every covenant contained in this Section 8
shall be specifically enforceable against the Pledgor.

            (j) Without in any way limiting the provisions of this Section 8,
upon the occurrence and during the continuance of an Event of Default, the Agent
may exercise in addition to all other rights and remedies granted to it in this
Agreement and in the Credit Agreement, all rights and remedies of a secured
party under the Uniform Commercial Code.

      Section 9. Application of Proceeds. Any cash held by the Agent as Pledged
Collateral and all cash proceeds received by the Agent in respect of any sale
of, liquidation of, or other realization upon all or any part of the Pledged
Collateral shall be applied by the Agent as follows:

            (a) First, to the payment of the costs and expenses of such sale,
liquidation or other realization, including reasonable compensation to the Agent
and its agents and counsel, and all expenses, liabilities and advances made or
incurred by the Agent in connection therewith;

            (b) Next, to the payment of the Secured Obligations; and


                                       10
<PAGE>   91
            (c) Finally, after payment in full of all Secured Obligations, to
the payment to the Pledgor, or its successors or assigns, or to whomsoever may
be lawfully entitled to receive the same or as a court of competent jurisdiction
may direct, of any surplus then remaining from such proceeds.

      Section 10. Waiver. No delay on the Agent's part in exercising any power
of sale, Lien, option or other right hereunder, and no notice or demand which
may be given to or made upon the Pledgor by the Agent with respect to any power
of sale, Lien, option or other right hereunder, shall constitute a waiver
thereof, or limit or impair the Agent's right to take any action or to exercise
any power of sale, Lien, option, or any other right hereunder, without notice or
demand, or prejudice the Agent's rights as against the Pledgor in any respect.

      Section 11. Assignment. The Agent may assign, endorse or transfer any
instrument evidencing all or any part of the Secured Obligations as provided in,
and in accordance with, the Credit Agreement, and the holder of such instrument
shall be entitled to the benefits of this Agreement.

      Section 12. Termination. Immediately following the Termination Date, the
Agent shall deliver to the Pledgor the Pledged Collateral subject to this
Agreement and all instruments of assignment executed in connection therewith,
free and clear of the Liens hereof, and any assignment required to be executed
by the Agent to effect such redelivery and, except as otherwise provided herein,
all of the Pledgor's obligations hereunder shall at such time terminate.

      Section 13. Lien Absolute. All rights of the Agent hereunder, and all
obligations of the Pledgor hereunder, shall be absolute and unconditional
irrespective of:

            (a) any lack of validity or enforceability of the Credit Agreement,
the Revolving Credit Notes, any other Lender Agreement or any other agreement or
instrument governing or evidencing any Secured Obligations;

            (b) any change in the time, manner or place of payment of, or in any
other term of, all or any part of the Secured Obligations, or any other
amendment or waiver of or any consent to any departure from the Credit
Agreement, the Revolving Credit Notes, any other Lender Agreement or any other
agreement or instrument governing or evidencing any Secured Obligations;

            (c) any exchange, release or non-perfection of any other collateral,
or any release or amendment or waiver of or consent to departure from any
guaranty, for all or any of the Secured Obligations; or

            (d) any other circumstance which might otherwise constitute a
defense available to, or a discharge of, the Pledgor.


                                       11
<PAGE>   92
      Section 14. Release. The Pledgor consents and agrees that the Agent may at
any time, or from time to time, in its discretion (a) renew, extend or change
the time of payment, and/or the manner, place or terms of payment of all or any
part of the Secured Obligations and (b) exchange, release and/or surrender all
or any of the Pledged Collateral, or any part thereof, by whomsoever deposited,
which is now or may hereafter be held by the Agent in connection with all or any
of the Secured Obligations; all in such manner and upon such terms as the Agent
may deem proper, and without notice to or further assent from the Pledgor, it
being hereby agreed that the Pledgor shall be and remain bound upon this
Agreement, irrespective of the existence, value or condition of any of the
Pledged Collateral, and notwithstanding any such change, exchange, settlement,
compromise, surrender, release, renewal or extension, and notwithstanding also
that the Secured Obligations may, at any time exceed the aggregate principal
amount thereof set forth in the Credit Agreement, or any other agreement
governing any Secured Obligations. The Pledgor hereby waives notice of
acceptance of this Agreement, and also presentment, demand, protest and notice
of dishonor of any and all of the Secured Obligations, and promptness in
commencing suit against any party hereto or liable hereon, and in giving any
notice to or of making any claim or demand hereunder upon the Pledgor. No act or
omission of any kind on the Agent's part shall in any event affect or impair
this Agreement.

      Section 15. Indemnification. The Pledgor agrees to indemnify the Agent and
its respective directors, officers, employees and agents and hold the Agent and
each such Person harmless from and against any and all losses, taxes,
liabilities, claims and damages, including reasonable attorneys' fees and
disbursements, and other expenses incurred or arising by reason of the taking or
the failure to take action by the Agent, in good faith, in respect of any
transaction effected under this Agreement, or in connection with the Lien
provided for herein, including, without limitation, any taxes payable in
connection with the delivery or registration of any of the Pledged Collateral as
provided herein (collectively "Indemnified Claims") or in connection with any
litigation, investigation or proceedings related to any of the foregoing.
Whether or not the transactions contemplated by this Agreement shall be
consummated, the Pledgor agrees to pay to the Agent all reasonable out-of-pocket

insolvent or make an assignment for the benefit of creditors or should a
receiver or trustee be appointed for all or any significant part of the
Pledgor's assets, and shall continue to be effective or be reinstated, as the
case may be, if at any time payment and performance of the Secured Obligations,
or any part thereof, is,


                                       12

record and the sole beneficial owner of the Pledged Collateral free and clear of
any Lien thereon or affecting the title thereto except for the Lien created by
this Agreement.

                 (b) All of the Pledged Shares have been duly authorized and
validly issued and all of the Pledged Shares representing shares of stock of
corporations are fully paid and non-assessable.

                 (c) The Pledgor has the right and requisite corporate authority
to pledge, assign, transfer, deliver, deposit and set over the Pledged
Collateral to the Agent, as provided herein.

                 (d) None of the Pledged Shares has been issued or transferred
in violation of the securities registration, securities disclosure or similar
laws of any jurisdiction to which such issuance or transfer may be subject.

                 (e) The authorized stock and other equity and beneficial
interests of each of the issuers listed on Schedule I hereto consists of the
number of shares of stock, with the number of shares issued and outstanding,
that are described on Schedule I hereto. As of the date hereof, there are no
existing options, warrants, calls or commitments of any character whatsoever
relating to any stock or other equity and beneficial interests of any of such
issuers.

                 (f) No consent, approval, authorization or other order of any
Person and no consent, authorization, approval, or other action by, and no
notice to or filing with, any governmental authority or regulatory body is
required either (i) for the pledge of the Pledged Collateral pursuant to this
Agreement or for the execution, delivery or performance of this Agreement by the
Pledgor or (ii) for the exercise by the Agent of the voting or other rights
provided for in this Agreement or the remedies in respect of the Pledged
Collateral pursuant to 


                                       3
<PAGE>   103
this Agreement including any disposition thereof, except as may be required in
connection with such disposition by laws affecting the offering and sale of
securities generally.

                 (g) The pledge, assignment and delivery of the Pledged
Collateral pursuant to this Agreement will create a valid first priority Lien on
and a first priority perfected security interest in the Pledged Collateral, and
the proceeds thereof, securing the payment of the Secured Obligations.

                 (h) This Agreement has been duly authorized, executed and
delivered by the Pledgor and constitutes a legal, valid and binding obligation
of the Pledgor enforceable in accordance with its terms, except as limited by
bankruptcy, insolvency, reorganization, moratorium or other laws affecting the
enforcement of creditors' rights generally, and except as the remedy of specific
performance or injunctive relief is subject to the discretion of the court
before which any proceeding therefor may be brought.

                 (i) The Pledged Shares constitute one hundred percent (100%) of
the issued and outstanding shares of stock or other equity and beneficial
interests of the issuers thereof.

                 (j) The Subsidiaries listed on Schedule III hereto are the only
Subsidiaries of the Pledgor.

         The representations and warranties set forth in this Section 5 shall
survive the execution and delivery of this Agreement.

         Section 6. Covenants. The Pledgor covenants and agrees that until the
Termination Date:

                 (a) Without the prior written consent of the Agent, the Pledgor
will not sell, assign, transfer, pledge, grant a Lien with respect to or
otherwise encumber any of its rights in or to the Pledged Collateral or any
unpaid dividends or other distributions or payments with respect thereto except
as otherwise permitted by the Credit Agreement.

                 (b) The Pledgor will, at its expense, promptly execute,
acknowledge and deliver all such instruments and take all such action as the
Agent from time to time may reasonably request in order to ensure to the Agent
the benefits of the Liens in and to the Pledged Collateral intended to be
created by this Agreement.

                 (c) The Pledgor will defend the title to the Pledged Collateral
and the Liens of the Agent thereon against the claim of any other Person and
will maintain and preserve such Liens until the Termination Date.

                 (d) The Pledgor will, upon obtaining any additional shares of
any Subsidiaries other than the Real Estate Subsidiary, if any, which shares are
not already Pledged Collateral, promptly (and in any event within three (3)
Business Days) deliver to the Agent a Pledge 


                                       4
<PAGE>   104
Amendment, duly executed by the Pledgor, in substantially the form of Schedule
II hereto (a "Pledge Amendment"), in respect of the additional Pledged Shares
which are to be pledged pursuant to this Agreement. The Pledgor hereby
authorizes the Agent to attach each such Pledge Amendment to this Agreement and
agrees that all Pledged Shares listed on any Pledge Amendment delivered to the
Agent shall for all purposes hereunder be considered Pledged Collateral.

shall have occurred and be continuing:

                 (a) The Pledgor shall have the right, from time to time, to
vote and give consents with respect to the Pledged Collateral or any part
thereof for all purposes not inconsistent with the provisions of this Agreement,
the Credit Agreement and any other Lender Agreement; provided, however, that no
vote shall be cast, and no consent shall be given or action taken, which would
have the effect of impairing the position or interest of the Agent in respect of
the Pledged Collateral or which would authorize or effect (except as and to the
extent expressly permitted by the Credit Agreement) (i) the dissolution or
liquidation, in whole or in part, of any of the Subsidiaries, (ii) the
consolidation or merger of any of the Subsidiaries with any other Person, (iii)
the sale, disposition or encumbrance of all or substantially all of the assets
of any of the Subsidiaries, (iv) any change in the authorized number of shares,
the stated capital or the authorized share capital of any of the Subsidiaries or
the issuance of any additional shares of its stock, or (v) the alteration of the
voting rights with respect to the stock of any of the Subsidiaries.

                  (b) (i) the Pledgor shall be entitled, from time to time, to
         collect and receive for its own use all cash dividends paid in respect
         of the Pledged Shares to the extent not in violation of the Credit
         Agreement other than any and all (A) dividends paid or payable other
         than in cash in respect of, and instruments and other property
         received, receivable or otherwise distributed in respect of, or in
         exchange for, any Pledged Collateral, (B) dividends and other
         distributions paid or payable in cash in respect of any Pledged
         Collateral in connection with a partial or total liquidation or
         dissolution and (C) cash paid, payable or otherwise distributed in
         redemption of, or in exchange for, any Pledged Collateral; provided,
         however, that until actually paid all rights to such dividends shall
         remain subject to the Lien created by this Agreement; and

                      (ii) all dividends (other than such cash dividends as are
         permitted to be paid to the Pledgor in accordance with clause (i)
         above) and all other distributions in respect of any of the Pledged
         Shares, whenever paid or made, shall be delivered to the Agent to hold
         as Pledged Collateral and shall, if received by the Pledgor, be
         received in trust for the benefit of the Agent, be segregated from the
         other property or funds of the Pledgor, and be forthwith delivered to
         the Agent as Pledged Collateral in the same form as so received (with
         any necessary endorsement).

is hereby authorized and empowered, to transfer and register in its name or in
the name of its nominee the whole or any part of the Pledged Collateral, to
exercise the voting rights with respect thereto, to collect and receive all cash
dividends and other distributions made thereon, to sell in one or more sales
after ten (10) days' notice of the time and place of any public sale or of the
time after which a private sale is to take place (which notice the Pledgor
agrees is commercially reasonable), but without any previous notice or
advertisement, the whole or any part of the Pledged Collateral and to otherwise
act and to exercise any and all rights with respect to the Pledged Collateral as
though the Agent was the outright owner thereof, the Pledgor hereby irrevocably
constituting and appointing the Agent as the proxy and attorney-in-fact of the
Pledgor, with full power of substitution to do so; provided, however, that the
Agent shall not have any duty to exercise any such right or to preserve the same
and shall not be liable for any failure to do so or for any delay in doing so.
Any sale shall be made at a public or private sale at the Agent's place of
business, or at any public building in the City of Boston, Massachusetts or
elsewhere to be named in the notice of sale, either for cash or upon credit or
for future delivery at such price as the Agent may deem fair, and the Agent may
be the purchaser of the whole or any part of the Pledged Collateral so sold and
hold the same thereafter in its own right free from any claim of the Pledgor or
any right of redemption. Each sale shall be made to the highest bidder, but the
Agent reserves the right to reject any and all bids at such sale which, in its
discretion, it shall reasonably deem inadequate. Demands of performance, except
as otherwise herein specifically provided for, notices of sale, advertisements
and the presence of property at sale are hereby waived and any sale hereunder
may be conducted by an auctioneer or any officer or agent of the Agent.

                  (b) If, at the original time or times appointed for the sale
of the whole or any part of the Pledged Collateral, the highest bid, if there be
but one sale, shall be inadequate to discharge in full all the Secured
Obligations, or if the Pledged Collateral be offered for sale in lots, if at any
of such sales, the highest bid for the lot offered for sale would indicate to
the Agent, in its reasonable discretion, the unlikelihood of the proceeds of the
sales of the whole of the Pledged Collateral being sufficient to discharge all
the Secured Obligations, the Agent may, on one or more occasions and in its
reasonable discretion, postpone any of said sales by public announcement at the
time of sale or the time of previous postponement of sale, and no other notice
of such postponement or postponements of sale need be given, any other notice
being hereby waived; provided, however, that any sale or sales made after such
postponement shall be after ten (10) days' notice to the Pledgor.

                  (c) In the event of any sales hereunder, the Agent shall,
after deducting all reasonable costs or expenses of every kind (including
reasonable attorneys' fees and disbursements) for care, safekeeping, collection,
sale, delivery or otherwise, apply the residue of the proceeds of the sales to
the payment or reduction, either in whole or in part, of the Secured Obligations
in accordance with the agreements and instruments governing and evidencing the
Secured Obligations, returning the surplus, if any, to the Pledgor.

<PAGE>   106
                  (d) If, at any time when the Agent in its reasonable
discretion determines, following the occurrence and during the continuance, of
an Event of Default, that, in connection with any actual or contemplated
exercise of its rights (when permitted under this Section 8) to sell the whole
or any part of the Pledged Collateral hereunder, it is necessary or advisable to
effect a public registration of all or part of the Pledged Collateral pursuant
to the Securities Act of 1933, as amended (or any similar statute then in
effect) (the "Act"), the Pledgor shall, in an expeditious manner, cause each of
its Subsidiaries other than the Real Estate Subsidiary, if any, to:

                       (i) prepare and file with the Securities and Exchange
         Commission (the "Commission") a registration statement with respect to
         the Pledged Collateral and use its best efforts to cause such
         registration statement to become and remain effective;

                       (ii) prepare and file with the Commission such amendments
         and supplements to such registration statement and the prospectus used
         in connection therewith as may be necessary to keep such registration
         statement effective and to comply with the provisions of the Act with
         respect to the sale or other disposition of the Pledged Collateral
         covered by such registration statement whenever the Agent shall desire
         to sell or otherwise dispose of the Pledged Collateral;

                       (iii) furnish to the Agent such numbers of copies of a
         prospectus and a preliminary prospectus, in conformity with the
         requirements of the Act, and such other documents as the Agent may
         reasonably request in order to facilitate the public sale or other
         disposition of the Pledged Collateral by the Agent;

                       (iv) use its best efforts to register or qualify the
         Pledged Collateral covered by such registration statement under such
         other securities or blue sky laws of such jurisdictions within the
         United States as the Agent shall reasonably request, and do such other
         reasonable acts and things as may be required of it to enable the Agent
         to consummate the public sale or other disposition in such
         jurisdictions of the Pledged Collateral by the Agent;

                       (v) use its best efforts to furnish, at the reasonable
         request of the Agent, on the date that shares of the Pledged Collateral
         are delivered to the underwriters for sale pursuant to such
         registration or, if the security is not being sold through
         underwriters, on the date that the registration statement with respect
         to such shares of the Pledged Collateral becomes effective, (A) an
         opinion, dated such date, of the outside counsel representing such
         registrant for the purposes of such registration, addressed to the
         underwriters, if any, and in the event the Pledged Collateral is not
         being sold through underwriters, then to the Agent, stating that such
         registration statement has become effective under the Act and that (1)
         to the best knowledge of such counsel, no stop order suspending the
         effectiveness thereof has been issued and no proceedings for that
         purpose have been instituted or are pending or threatened under the
         Act, (2) the registration statement, the related prospectus, and each
         amendment or

                                        7
<PAGE>   107
         supplement thereto, comply as to form in all material respects with the
         requirements of the Act and the applicable rules and regulations of the
         Commission thereunder (except that such counsel need express no opinion
         as to financial statements or other financial or statistical data
         contained therein), (3) such counsel has no reason to believe that
         either the registration statement or the prospectus, or any amendment
         or supplement thereto, contains any untrue statement of a material fact
         or omits a material fact required to be stated therein or necessary to
         make the statements therein not misleading, (4) the descriptions in the
         registration statement or the prospectus, or any amendment or
         supplement thereto, of all legal matters and contracts and other legal
         documents or instruments are accurate in all material respects and
         fairly present the information required to be shown and (5) such
         counsel does not know of any legal or governmental proceedings, pending
         or threatened, required to be described in the registration statement
         or prospectus, or any amendment or supplement thereto, or to be filed
         as exhibits to the registration statement which are not described and
         filed or incorporated by reference as required; and (B) a letter, dated
         such date, from the independent certified public accountants of such
         registrant, addressed to the underwriters, if any, and in the event the
         Pledged Collateral is not being sold through underwriters, then to the
         Agent, stating that they are independent certified public accountants
         within the meaning of the Act and that, in the opinion of such
         accountants, the financial statements and other financial data of such
         registrant included in the registration statement or the prospectus, or
         any amendment or supplement thereto, comply as to form in all material
         respects with the applicable accounting requirements of the Act. The
         opinion of counsel referred to above shall additionally cover such
         other legal matters with respect to the registration in respect of
         which such opinion is being given as the Agent may reasonably request.
         The letter referred to above from the independent certified public
         accountants shall additionally cover such other financial matters
         (including information as to the period ending not more than five (5)
         Business Days prior to the date of such letter) with respect to the
         registration in respect of which such letter is being given as the
         Agent may reasonably request; and

                       (vi) otherwise use its best efforts to comply with all
         applicable rules and regulations of the Commission, and not later than
         18 months after the effective date of the registration statement, make
         available to the Agent an earnings statement (which need not be
         audited) covering a period of at least 12 months beginning the first
         full month after the effective date of such registration statement
         which earnings statement shall satisfy the provisions of Rule 158
         promulgated under the Act.

                  (e) All expenses incurred in complying with Section 8(d)
hereof, including, without limitation, all registration and filing fees
(including all expenses incident to filing with the National Association of
Securities Dealers, Inc.), printing expenses, fees and disbursements of counsel
for the registrant, the reasonable fees and expenses of counsel for the Agent,
expenses of the independent certified public accountants (including any special
audits incident to or required by any such registration) and expenses of
complying with the securities or blue sky laws or any jurisdictions, shall be
paid by the Pledgor.

                                        8
<PAGE>   108
                  (f) If, at any time when the Agent shall determine to exercise
its rights to sell the whole or any part of the Pledged Collateral hereunder,
such Pledged Collateral or the part thereof to be sold shall not, for any reason
whatsoever, be effectively registered under the Act, the Agent may, in its
discretion (subject only to applicable requirements of law), sell such Pledged
Collateral or part thereof by private sale in such manner and under such
circumstances as the Agent may deem necessary or advisable, but subject to the
other requirements of this Section 8, and shall not be required to effect such
registration or to cause the same to be effected. Without limiting the
generality of the foregoing, in any such event the Agent in its discretion (i)
may, in accordance with applicable securities laws, proceed to make such private
sale notwithstanding that a registration statement for the purpose of
registering such Pledged Collateral or part thereof could be or shall have been
filed under the Act (or similar statute), (ii) may approach and negotiate with a
single possible purchaser to effect such sale and (iii) may restrict such sale
to a purchaser who will represent and agree that such purchaser is purchasing
for its own account, for investment and not with a view to the distribution or
sale of such Pledged Collateral or part thereof. In addition to a private sale
as provided above in this Section 8, if any of the Pledged Collateral shall not
be freely distributable to the public without registration under the Act (or
similar statute) at the time of any proposed sale pursuant to this Section 8,
then the Agent shall not be required to effect such registration or cause the
same to be effected but, in its discretion (subject only to applicable
requirements of law), may require that any sale hereunder (including a sale at
auction) be conducted subject to restrictions (A) as to the financial
sophistication and ability of any Person permitted to bid or purchase at any
such sale, (B) as to the content of legends to be placed upon any certificates
representing the Pledged Collateral sold in such sale, including restrictions on
future transfer thereof, (C) as to the representations required to be made by
each Person bidding or purchasing at such sale relating to that Person's access
to financial information about the Pledgor and such Person's intentions as to
the holding of the Pledged Collateral so sold for investment, for its own
account, and not with a view of the distribution thereof and (D) as to such
other matters as the Agent may, in its discretion, deem necessary or appropriate
in order that such sale (notwithstanding any failure so to register) may be
effected in compliance with the Uniform Commercial Code and other laws affecting
the enforcement of creditors' rights and the Act and all applicable state
securities laws.

                  (g) The Pledgor acknowledges that notwithstanding the legal
availability of a private sale or a sale subject to the restrictions described
above in paragraph (f), the Agent may, in its discretion, elect to register any
or all the Pledged Collateral under the Act (or any applicable state securities
law) in accordance with its rights hereunder. The Pledgor, however, recognizes
that the Agent may be unable to effect a public sale of any or all the Pledged
Collateral and may be compelled to resort to one or more private sales thereof.
The Pledgor also acknowledges any such private sale (conducted in a commercially
reasonable manner for private sales) may result in prices and other terms less
favorable to the seller than if such sale were a public sale and,
notwithstanding such circumstances, agrees that any such private sale shall be
deemed to have been made in a commercially reasonable manner. The Agent shall be
under no obligation to delay a sale of any of the Pledged Collateral for the
period of time necessary to permit the registrant to register such securities
for public sale under the Act, or

                                        9
<PAGE>   109
under applicable state securities laws, even if the Pledgor or issuer of the
Pledged Collateral would agree to do so.

                  (h) The Pledgor agrees that following the occurrence an Event
of Default, it will not at any time plead, claim or take the benefit of any
appraisal, valuation, stay, extension, moratorium or redemption law now or
hereafter in force in order to prevent or delay the enforcement of this
Agreement, or the absolute sale of the whole or any part of the Pledged
Collateral or the possession thereof by any purchaser at any sale hereunder in
accordance with the terms hereof, and the Pledgor waives the benefit of all such
laws to the extent it lawfully may do so. The Pledgor agrees that it will not
interfere with any right, power and remedy of the Agent provided for in this
Agreement or now or hereafter existing at law or in equity or by statute or
otherwise, or the exercise or beginning of the exercise by the Agent of any one
or more of such rights, powers, or remedies. No failure or delay on the part of
the Agent to exercise any such right, power or remedy and no notice or demand
which may be given to or made upon the Pledgor by the Agent with respect to any
such remedies shall operate as a waiver thereof, or limit or impair the Agent's
right to take any action or to exercise any power or remedy hereunder, without
notice or demand, or prejudice its rights as against the Pledgor in any respect.

                  (i) The Pledgor further agrees that a breach of any of the
covenants contained in this Section 8 will cause irreparable injury to the
Agent, that the Agent has no adequate remedy at law in respect of such breach
and, as a consequence, agrees that each and every covenant contained in this
Section 8 shall be specifically enforceable against the Pledgor.

                  (j) Without in any way limiting the provisions of this Section
8, upon the occurrence and during the continuance of an Event of Default, the
Agent may exercise in addition to all other rights and remedies granted to it in
this Agreement and in the Credit Agreement, all rights and remedies of a secured
party under the Uniform Commercial Code.

         Section 9. Application of Proceeds. Any cash held by the Agent as
Pledged Collateral and all cash proceeds received by the Agent in respect of any
sale of, liquidation of, or other realization upon all or any part of the
Pledged Collateral shall be applied by the Agent as follows:

                  (a) First, to the payment of the costs and expenses of such
sale, liquidation or other realization, including reasonable compensation to the
Agent and its agents and counsel, and all expenses, liabilities and advances
made or incurred by the Agent in connection therewith;

                  (b) Next, to the payment of the Secured Obligations; and

                  (c) Finally, after payment in full of all Secured Obligations,
to the payment to the Pledgor, or its successors or assigns, or to whomsoever
may be lawfully entitled to receive

                                       10
<PAGE>   110
the same or as a court of competent jurisdiction may direct, of any surplus then
remaining from such proceeds.

         Section 10. Waiver. No delay on the Agent's part in exercising any
power of sale, Lien, option or other right hereunder, and no notice or demand
which may be given to or made upon the Pledgor by the Agent with respect to any
power of sale, Lien, option or other right hereunder, shall constitute a waiver
thereof, or limit or impair the Agent's right to take any action or to exercise
any power of sale, Lien, option, or any other right hereunder, without notice or
demand, or prejudice the Agent's rights as against the Pledgor in any respect.

         Section 11. Assignment. The Agent may assign, endorse or transfer any
instrument evidencing all or any part of the Secured Obligations as provided in,
and in accordance with, the Credit Agreement, and the holder of such instrument
shall be entitled to the benefits of this Agreement.

         Section 12. Termination. Immediately following the Termination Date,
the Agent shall deliver to the Pledgor the Pledged Collateral subject to this
Agreement and all instruments of assignment executed in connection therewith,
free and clear of the Liens hereof, and any assignment required to be executed
by the Agent to effect such redelivery and, except as otherwise provided herein,
all of the Pledgor's obligations hereunder shall at such time terminate.

         Section 13. Lien Absolute. All rights of the Agent hereunder, and all
obligations of the Pledgor hereunder, shall be absolute and unconditional
irrespective of:

                  (a) any lack of validity or enforceability of the Credit
Agreement, the Revolving Credit Notes, any other Lender Agreement or any other
agreement or instrument governing or evidencing any Secured Obligations;

                  (b) any change in the time, manner or place of payment of, or
in any other term of, all or any part of the Secured Obligations, or any other
amendment or waiver of or any consent to any departure from the Credit
Agreement, the Revolving Credit Notes, any other Lender Agreement or any other
agreement or instrument governing or evidencing any Secured Obligations;

                  (c) any exchange, release or non-perfection of any other
collateral, or any release or amendment or waiver of or consent to departure
from any guaranty, for all or any of the Secured Obligations; or

                  (d) any other circumstance which might otherwise constitute a
defense available to, or a discharge of, the Pledgor.

         Section 14. Release. The Pledgor consents and agrees that the Agent may
at any time, or from time to time, in its discretion (a) renew, extend or change
the time of payment,

                                       11
<PAGE>   111
and/or the manner, place or terms of payment of all or any part of the Secured
Obligations and (b) exchange, release and/or surrender all or any of the Pledged
Collateral, or any part thereof, by whomsoever deposited, which is now or may
hereafter be held by the Agent in connection with all or any of the Secured
Obligations; all in such manner and upon such terms as the Agent may deem
proper, and without notice to or further assent from the Pledgor, it being
hereby agreed that the Pledgor shall be and remain bound upon this Agreement,
irrespective of the existence, value or condition of any of the Pledged
Collateral, and notwithstanding any such change, exchange, settlement,
compromise, surrender, release, renewal or extension, and notwithstanding also
that the Secured Obligations may, at any time exceed the aggregate principal
amount thereof set forth in the Credit Agreement, or any other agreement
governing any Secured Obligations. The Pledgor hereby waives notice of
acceptance of this Agreement, and also presentment, demand, protest and notice
of dishonor of any and all of the Secured Obligations, and promptness in
commencing suit against any party hereto or liable hereon, and in giving any
notice to or of making any claim or demand hereunder upon the Pledgor. No act or
omission of any kind on the Agent's part shall in any event affect or impair
this Agreement.

         Section 15. Indemnification. The Pledgor agrees to indemnify the Agent
and its respective directors, officers, employees and agents and hold the Agent
and each such Person harmless from and against any and all losses, taxes,
liabilities, claims and damages, including reasonable attorneys' fees and
disbursements, and other expenses incurred or arising by reason of the taking or
the failure to take action by the Agent, in good faith, in respect of any
transaction effected under this Agreement, or in connection with the Lien
provided for herein, including, without limitation, any taxes payable in
connection with the delivery or registration of any of the Pledged Collateral as
provided herein (collectively "Indemnified Claims") or in connection with any
litigation, investigation or proceedings related to any of the foregoing.
Whether or not the transactions contemplated by this Agreement shall be
consummated, the Pledgor agrees to pay to the Agent all reasonable out-of-pocket
costs and expenses incurred in connection with this Agreement and all reasonable
fees, expenses and disbursements, and the reasonable fees of the Agent's agents
or representatives, incurred in connection with the execution and delivery of
this Agreement and the performance by the Agent of the provisions of this
Agreement and of any transactions effected in connection with this Agreement.
The obligations of the Pledgor under this Section 15 shall survive the
termination of this Agreement. The foregoing notwithstanding, the indemnity
provided for herein shall not apply to any Indemnified Claim of the Agent if a
court of competent jurisdiction determines that such Indemnified Claim is the
result of the gross negligence or willful misconduct of the Agent.

         Section 16. Reinstatement. This Agreement shall remain in full force
and effect and continue to be effective should any petition be filed by or
against the Pledgor for liquidation or reorganization, should the Pledgor become
insolvent or make an assignment for the benefit of creditors or should a
receiver or trustee be appointed for all or any significant part of the
Pledgor's assets, and shall continue to be effective or be reinstated, as the
case may be, if at any time payment and performance of the Secured Obligations,
or any part thereof, is, pursuant to applicable law, rescinded or reduced in
amount, or must otherwise be restored or

                                       12
<PAGE>   112
returned, and in any such case, the Secured Obligations shall be reinstated and
deemed reduced only by such amount paid and not so rescinded, reduced, restored
or returned.

         Section 17. Miscellaneous.

                  (a) The Agent may execute any of its duties hereunder by or
through agents or employees and shall be entitled to advice of counsel
concerning all matters pertaining to its duties hereunder.

                  (b) The Pledgor agrees to promptly reimburse the Agent for
actual and reasonable out-of-pocket expenses, including, without limitation,
reasonable counsel fees, incurred by the Agent in connection with the
administration and enforcement of this Agreement.

                  (c) Neither the Agent nor any of its officers, directors,
employees, agents or counsel shall be liable for any action lawfully taken or
omitted to be taken by it or them hereunder or in connection herewith, except
for its or their own gross negligence or willful misconduct.

                  (d) This Agreement shall be binding upon the Pledgor and its
successors and assigns, and shall inure to the benefit of, and be enforceable
by, the Agent and its respective successors and assigns, and shall be governed
by, and construed and enforced in accordance with, the internal laws in effect
in the Commonwealth of Massachusetts without giving effect to principles of
choice of law, and none of the terms or provisions of this Agreement may be
waived, altered, modified or amended except in writing duly signed for and on
behalf of the Agent and the Pledgor.

                  (e) At any time and from time to time, upon written request of
the Agent, and at the sole expense of the Pledgor, the Pledgor shall promptly
and duly execute and deliver any and all such further instruments and documents
and take such further action as the Agent may reasonably deem desirable to
obtain the full benefits of this Agreement and of the rights and powers herein
granted.

         Section 18. Severability. If for any reason any provision or provisions
hereof are determined to be invalid and contrary to any existing or future law,
such invalidity shall not impair the operation of or effect those portions of
this Agreement which are valid.

         Section 19. Notices. Except as otherwise provided herein, whenever it
is provided herein that any notice, demand, request, consent, approval,
declaration or other communication shall or may be given to or served upon any
of the parties by any other party, or whenever any of the parties desires to
give or serve upon any other a communication with respect to this Agreement,
each such notice, demand, request, consent, approval, declaration or other

                                    ARTICLE 2

                GENERAL REPRESENTATIONS, WARRANTIES AND COVENANTS

         Each Debtor represents, warrants and covenants, which representations,
warranties and covenants shall survive execution and delivery of this Agreement,
as follows:

         Section 2.1 Necessary Filings. All filings, registrations and
recordings necessary or appropriate to create, preserve and perfect the security
interest granted by each Debtor to the Agent hereby in respect of the Collateral
have been accomplished and the security interest granted to the Agent pursuant
to this Agreement in and to the Collateral constitutes, upon satisfaction of
such filings, registrations and recordings, a perfected security interest
therein (to the extent that the same can be perfected by filing, registration or
recording) prior to the rights of all other Persons therein (other than any such
rights pursuant to Liens permitted by Section 9.2 of the Credit Agreement
("Permitted Liens")) and subject to no other Liens (other than Permitted Liens)
and is entitled to all the rights, priorities and benefits afforded by the
Uniform Commercial Code to perfected security interests.

         Section 2.2 No Liens. Each Debtor is, and as to Collateral acquired by
it from time to time after the date hereof each such Debtor will be, the owner
of all Collateral pledged by it hereunder free from any Lien, security interest,
encumbrance or other right, title or interest of any Person (other than
Permitted Liens), and each such Debtor shall defend the Collateral against all
claims and demands of all Persons at any time claiming the same or any interest
therein (other than in connection with Permitted Liens) adverse to the Agent.

         Section 2.3 Other Financing Statements. As of the date hereof, there is
no financing statement (or similar statement or instrument of registration under
the law of any jurisdiction) covering or purporting to cover any interest of any
kind in the Collateral (other than financing statements filed in respect of
Permitted Liens), and so long as any Lender Obligations or commitments with
respect thereto are outstanding, no Debtor will execute or authorize to be filed
in any public office any financing statement (or similar statement or instrument
of registration under the law of any jurisdiction) or statements relating to the
Collateral, except financing statements filed or to be filed in respect of and
covering the security interests granted hereby by such Debtors or in connection
with Permitted Liens.

         Section 2.4 Chief Executive Office; Records. As of the date hereof, the
chief executive office of each such Debtor is located at the address indicated
on Exhibit A hereto. No Debtor will move its chief executive office except to
such new location as any Debtor may establish in accordance with the last
sentence of this Section 2.4. A complete set of books of account and records of
each Debtor relating to the Receivables and the Contract Rights are, and will
continue to be, kept at such chief executive office, at one or more of the other
record locations set forth on Exhibit A hereto for each such Debtor or at such
new locations as each Debtor may establish in accordance with the last sentence
of this Section 2.4. All Receivables 


                                       3
<PAGE>   122
and Contract Rights of each Debtor are, and will continue to be, maintained at,
and controlled and directed (including, without limitation, for general
accounting purposes) from, the office locations described above or such new
location established in accordance with the last sentence of this Section 2.4.
No Debtor shall establish new locations for such offices until (a) it shall have
given to the Agent not less than ten (10) days' prior written notice of its
intention to do so, clearly describing such new location and providing such
other information in connection therewith as the Agent may reasonably request
and (b) with respect to such new location, it shall have taken all action
reasonably satisfactory to the Agent, to maintain the security interest of the
Agent in the Collateral intended to be granted hereby at all times fully
perfected and in full force and effect.

         Section 2.5 Location of Inventory and Equipment. As of the date hereof,
all Inventory and Equipment held by each Debtor is located at one of the
locations shown on Exhibit B hereto for each Debtor. Each Debtor agrees that all
Inventory and Equipment now held or subsequently acquired by it shall be kept at
(or shall be in transport to) any one of the locations shown on Exhibit B
hereto, or such new location as any Debtor may establish in accordance with the
last sentence of this Section 2.5. A Debtor may establish a new location for
Inventory and Equipment only if (a) it shall have given to the Agent not less
than ten (10) days' prior written notice of its intention so to do, clearly
describing such new location and providing such other information in connection
therewith as the Agent may reasonably request and (b) with respect to such new
location, it shall have taken all action reasonably satisfactory to the Agent to
maintain the security interest of the Agent in the Collateral intended to be
granted hereby at all times fully perfected and in full force and effect.

         Section 2.6 Recourse. This Agreement is made with full recourse to each
Debtor and pursuant to and upon all the warranties, representations, covenants
and agreements on the part of each Debtor contained herein, in the other Lender
Agreements and otherwise in writing in connection herewith or therewith.

Debtor operates in any jurisdiction under, or in the preceding 12 months has not
operated in any jurisdiction under, any trade names, fictitious names or other
names except its legal name and except as disclosed on Exhibit F hereto. No
Debtor shall change its legal name or assume or operate in any jurisdiction
under any trade, fictitious or other name except as established in accordance
with the last sentence of this Section 2.7. Each Debtor shall not assume or
operate in any jurisdiction under any new trade, fictitious or other name until
(a) it shall have given to the Agent ten (10) days' prior written notice of its
intention so to do, clearly describing such new name and the jurisdictions in
which such new name shall be used and providing such other information in
connection therewith as the Agent may reasonably request and (b) with respect to
such new name, it shall have taken all action reasonably requested by the Agent,
to maintain the security interest of the Agent in the Collateral intended to be

                                    ARTICLE 3

                          SPECIAL PROVISIONS CONCERNING
                    RECEIVABLES; CONTRACT RIGHTS; INSTRUMENTS

         Section 3.1 Additional Representations and Warranties. As of the time
when each of its Receivables arises, each Debtor shall be deemed to have
represented and warranted that such Receivable, and all records, papers and
documents relating thereto, are what they purport to be in all material
respects, and that such Receivable will, to the best knowledge of each Debtor,
evidence true and valid obligations of the account debtor named therein.

         Section 3.2 Maintenance of Records. Each Debtor will keep and maintain
at its own cost and expense, records of its Receivables and Contracts and each
Debtor will make the same available on Debtor's premises to the Agent for
inspection, at the Debtor's own cost and expense, at any and all reasonable
times upon reasonable prior notice to the Debtor. Each Debtor shall affix to
each writing constituting chattel paper, and if the Agent so directs to all
other Receivables and Contracts, as well as books, records and documents of each
Debtor evidencing or pertaining to such Receivables and Contracts, an
appropriate reference, in form and manner satisfactory to the Agent, to the fact
that such chattel paper, Receivables and Contracts have been assigned to the
Agent and that the Agent has a security interest therein. Upon the occurrence
and during the continuance of an Event of Default, and at the reasonable request
of the Agent, each Debtor shall, at its own cost and expense, deliver all
tangible evidence of its Receivables and Contract Rights (including, without
limitation, all documents evidencing the Receivables and all Contracts and each
specific writing constituting chattel paper) and such books and records to the
Agent or to its representatives (copies of which evidence and books and records
may be retained by each Debtor).

         Section 3.3 Direction to Account Debtors; Contracting Parties; Etc.
Upon the occurrence and during the continuance of an Event of Default, and if
the Agent so directs, each Debtor agrees (a) to cause all payments on account of
the Receivables and Contracts to be made directly to the Cash Collateral
Account, (b) that the Agent may, at its option, directly notify the obligors
with respect to any Receivables and/or under any Contracts to make payments with
respect thereto as provided in preceding clause (a) and (c) that the Agent may
enforce collection of any such Receivables and Contracts and may adjust, settle
or compromise the amount of payment thereof, in the same manner and to the same
extent as such Debtors. Without notice to or assent by the Debtors, upon the
occurrence and during the continuance of an Event of Default, the Agent may
apply any or all amounts then in, or thereafter deposited in, the Cash
Collateral Account which application shall be effected in the manner provided in
Section 7.4 of this Agreement. The reasonable costs and expenses (including
reasonable

                                        5
<PAGE>   124
attorneys' fees) of collection, whether incurred by any Debtor or the Agent,
shall be borne by the Debtors. The Agent shall deliver a copy of each notice
referred to in the preceding clause (b) to the Debtors; provided, that the
failure by the Agent to so notify any Debtor shall not affect the effectiveness
of such notice or the other rights of the Agent created by this Section 3.3.

         Section 3.4 Modification of Terms; Etc. No Debtor may rescind or cancel
any indebtedness evidenced by any Receivable or under any Contract, or modify
any term thereof or make any adjustment with respect thereto in a manner adverse
to the Agent, or extend or renew the same, or compromise or settle any material
dispute, claim, suit or legal proceeding relating thereto in a manner adverse to
the Agent, or sell any Receivable or Contract, or interest therein, without the
prior written consent of the Agent, except in accordance with the Debtor's
reasonable business practices.

         Section 3.5 Collection. Each Debtor shall endeavor, in accordance with
reasonable business practices, to cause to be collected from the account debtor
named in each of its Receivables or obligor under any Contract, as and when due
(including, without limitation, amounts which are delinquent, such amounts to be
collected in accordance with generally accepted lawful collection procedures)
any and all amounts owing under or on account of such Receivable or Contract,
and apply forthwith upon receipt thereof all such amounts as are so collected to
the outstanding balance of such Receivable or under such Contract. The
reasonable costs and expenses (including, without limitation, reasonable
attorneys' fees) of collection, if incurred by any Debtor or the Agent, shall be
borne by the Debtors.

         Section 3.6 Instruments. If any Debtor owns or acquires any Instrument
constituting Collateral, the Debtor will within 10 Business Days notify the
Agent thereof, and upon request by the Agent, will promptly deliver such
Instrument to the Agent appropriately endorsed to the order of the Agent as
further security hereunder.


                                    ARTICLE 4

                    SPECIAL PROVISIONS CONCERNING TRADEMARKS

         Section 4.1 Additional Representations and Warranties. Except as set
forth on Schedule 5.16 to the Credit Agreement, each Debtor represents and
warrants that: (i) as of the date hereof, it is the true and lawful owner of all
right, title and interest to, or otherwise has the right to use, the registered
Marks listed on Exhibit C hereto for each Debtor and that, as of the date
hereof, said listed Marks constitute all the marks and applications for marks
registered in the United States Patent and Trademark Office that each Debtor
presently owns or uses in connection with its business; (ii) it owns, is
licensed to use or otherwise has the right to use all Marks that it uses; (iii)
it has no knowledge of any third party claim that any aspect of the Debtor's
present or contemplated business operations infringe or will infringe any
trademark, service mark or trade name in any respect which could reasonably be
expected to have a

                                        6
<PAGE>   125
Material Adverse Effect on each Debtor and its Subsidiaries taken as a whole;
and (iv) except as listed on Exhibit C, as of the date hereof, it is the
beneficial and record owner of all trademark registrations and applications
listed on Exhibit C hereto for each Debtor and that said registrations are valid
and subsisting, and that no Debtor is aware of any third-party claim that any of
said registrations in respect of any Mark is invalid or unenforceable. Each
Debtor hereby grants to the Agent an absolute power of attorney to sign, upon
the occurrence and during the continuance of an Event of Default, any document
which may be required by the United States Patent and Trademark Office in order
to effect an absolute assignment of all right, title and interest in each Mark,
and record the same.

         Section 4.2 Infringements. Each Debtor agrees, promptly upon learning
thereof, to notify the Agent in writing of the name and address of, and to
furnish such pertinent information that may be available with respect to, any
party who the Debtor believes is infringing or diluting or otherwise violating
in any material respect any of the Debtor's rights in and to any Mark, or with
respect to any party claiming that the Debtor's use of any Mark violates in any
material respect any property right of that party. Each Debtor further agrees to
prosecute any Person infringing any Mark in accordance with reasonable business
practices.

         Section 4.3 Preservation of Marks. Each Debtor agrees to use its Marks
as required in each of the applicable jurisdictions during the time in which
this Agreement is in effect, sufficiently to preserve such Marks (and any
registrations thereto) as trademarks or service marks under the laws of the
United States and any other applicable law; provided, that, prior to any
Default, no Debtor shall be obligated to preserve any Mark in the event the
Debtor determines, in its reasonable business judgment, that the preservation of
such Mark is no longer desirable in the conduct of its business.

         Section 4.4 Maintenance of Registration. Each Debtor shall, at its own
expense, diligently process all documents required by the Trademark Act of 1946,
15 U.S.C. Sections 1051 et seq. to maintain trademark registrations,
including but not limited to affidavits of use and applications for renewals of
registration in the United States Patent and Trademark Office for all of its
registered Marks pursuant to 15 U.S.C. Sections 1058(a), 1059 and 1065,
and shall pay all fees and disbursements in connection therewith and shall not
abandon any such filing of affidavit of use or any such application of renewal
prior to the exhaustion of all administrative and judicial remedies without
prior written consent of the Agent (which consent shall not be unreasonably
withheld); provided, that, prior to any Default, no Debtor shall be obligated to
maintain any Mark in the event that the Debtor determines, in its reasonable
business judgment, that the maintenance of such Mark is no longer necessary or
desirable in the conduct of its business.

         Section 4.5 Future Registered Marks. If any Mark registration issues
hereafter to any Debtor as a result of any application now or hereafter pending
before the United States Patent and Trademark Office, within sixty (60) days of
receipt of such certificate, such Debtor shall deliver to the Agent a copy of
such certificate, and an assignment for security in such Mark, to the Agent and
at the expense of such Debtor, confirming the assignment for security

                                        7
<PAGE>   126
in such Mark to the Agent hereunder, the form of such security to be
substantially the same as the form hereof or in such other form as may be
reasonably satisfactory to the Agent.

         Section 4.6 Remedies. Upon the occurrence and during the continuance of
an Event of Default, the Agent may take any or all of the following actions: (a)
declare the entire right, title and interest of any Debtor in and to each of the
Marks, together with all trademark rights and rights of protection to the same,
vested in the Agent, for the benefit of the Lenders, in which event such rights,
title and interest shall immediately vest in the Agent, for the benefit of the
Lenders, and the Agent shall be entitled to exercise the power of attorney
referred to in Section 4.1 hereof to execute, cause to be acknowledged and
notarized and to record said absolute assignment with the applicable agency; (b)
take and use or sell the Marks and the goodwill of such Debtor's business
symbolized by the Marks or carry on the business and use the assets of such
Debtor which have been used in connection with the Marks; and (c) direct the
Debtor to refrain, in which event the Debtor shall refrain, from using the Marks
in any manner whatsoever, directly or indirectly, and, if requested by the
Agent, change the Debtor's corporate name to eliminate therefrom any use of any
Mark and execute such other and further documents that the Agent may request to
further confirm this and to transfer ownership of the Marks and registrations
and any pending trademark application in the United States Patent and Trademark
Office to the Agent.

         Section 4.7 Collateral Assignment. In addition to, and not in
limitation of, the grant of the security interest in Article 1 above, each
Debtor hereby grants, assigns, transfers, conveys and sets over to the Agent,
for the benefit of the Lenders, effective upon the occurrence and during the
continuance of an Event of Default, each Debtor's entire right, title and
interest in and to the Marks, the goodwill of the business symbolized by the
Marks and Proceeds. Each Debtor has delivered to the Agent an Assignment of
Trademarks (the "Assignment") and upon the occurrence and during the continuance
of an Event of Default, the Agent is hereby authorized to file such Assignment
with the United States Patent and Trademark Office. Upon payment in full of all
Obligations, the Agent will assign the Marks to the Debtor.


                                    ARTICLE 5

                          SPECIAL PROVISIONS CONCERNING
                      PATENTS, COPYRIGHTS AND TRADE SECRETS

         Section 5.1 Additional Representations and Warranties. Except as set
forth on Schedule 5.16 to the Credit Agreement, each Debtor represents and
warrants that, as of the date hereof, it is the true and lawful owner of all
rights in (a) all Trade Secrets and Proprietary Information necessary to operate
its business, (b) the Patents listed on Exhibit D hereto for each Debtor, said
Patents constituting all the patents and applications for patents that each
Debtor owns on the date hereof and (c) the Copyrights listed on Exhibit E hereto
for each Debtor, said Copyrights constituting all registrations of copyrights
and applications for

                                        8
<PAGE>   127
copyright registrations that each such Debtor owns on the date hereof. Each
Debtor further warrants that it has no knowledge of any third party claim that
any aspect of its present or contemplated business operations infringe or will
infringe any patent or any copyright or that it has misappropriated any Trade
Secret or Proprietary Information, in each case in any respect which could
reasonably be expected to have a Material Adverse Effect on such Debtor and its
Subsidiaries taken as a whole. Each Debtor hereby grants to the Agent an
absolute power of attorney to sign, upon the occurrence and during the
continuance of an Event of Default, any document which may be required by the
United States Patent and Trademark Office or the United States Copyright Office
in order to effect an absolute assignment of all right, title and interest in
each Patent and Copyright, and to record the same.

         Section 5.2 Infringements. Each Debtor agrees, promptly upon learning
thereof, to furnish to the Agent in writing all pertinent information available
to such Debtor with respect to any infringement, contributing infringement or
active inducement to infringe in any material respect any Patent or Copyright or
to any claim that the practice of any Patent or the use of any Copyright
violates in any material respect any property right of a third party, or with
respect to any misappropriation of any Trade Secret right or any claim that
practice of any material Trade Secret right violates in any material respect any
property right of a third party. Each Debtor further agrees, to the extent
consistent with reasonable business practices, to prosecute any Person
infringing any Patent or Copyright or any Person misappropriating any Trade
Secret right.

         Section 5.3 Maintenance of Patents. At its own expense, each Debtor
shall make timely payment of all post-issuance fees required pursuant to 35
U.S.C. Section 41 to maintain in force rights under each Patent, absent prior
written consent of the Agent; provided, that no Debtor shall be obligated to
maintain any Patent in the event the Debtor determines, in its reasonable
business judgment, that the maintenance of such Patent is no longer necessary or
desirable in the conduct of its business.

         Section 5.4 Prosecution of Patent Application. At its own expense, such
Debtor shall diligently prosecute all applications for Patents for such Debtor
and shall not abandon any such application prior to exhaustion of all
administrative and judicial remedies, absent written consent of the Agent (which
consent shall not be unreasonably withheld); provided, that no Debtor shall be
obligated to prosecute any application in the event the Debtor determines, in
its reasonable business judgment, that the prosecuting of such application is no
longer necessary or desirable in the conduct of its business.

         Section 5.5 Other Patents and Copyrights. Within sixty (60) days of the
acquisition or issuance of a Patent, registration of a Copyright, or acquisition
of a registered copyright, the Debtor shall deliver to the Agent a copy of said
Copyright or certificate or registration of said patents, as the case may be,
with an assignment for security as to such Patent or Copyright, as the case may
be, to the Agent and at the expense of the Debtor, confirming the assignment for
security, the form of such assignment for security to be substantially the same
as the form hereof or in such other form as may be reasonably satisfactory to
the Agent.

         Section 5.6 Remedies. Upon the occurrence and during the continuance of
an Event of Default, the Agent may take any or all of the following actions: (a)
declare the entire right, title, and interest of any Debtor in each of the
Patents and Copyrights vested in the Agent, for the benefit of the Lenders, in
which event such right, title, and interest shall immediately vest in the Agent,
for the benefit of the Lenders, and in which case the Agent shall be entitled to
exercise the power of attorney referred to in Section 5.1 hereof to execute,
cause to be acknowledged and notarized and to record said absolute assignment
with the applicable agency; (b) take and practice, use or sell the Patents and
Copyrights; and (c) direct such Debtor to refrain, in which event such Debtor
shall refrain, from practicing the Patents and using the Copyrights, directly or
indirectly, and such Debtor shall execute such other and further documents as
the Agent may request further to confirm this and to transfer ownership of the
Patents and Copyrights to the Agent, for the benefit of the Lenders.


                                    ARTICLE 6

                      PROVISIONS CONCERNING ALL COLLATERAL

         Section 6.1 Protection of Agent's Security. Each Debtor will at all
times keep its Inventory and Equipment insured in favor of the Agent, at each
such Debtor's own expense to the extent and in the manner provided in the Lender
Agreements; all policies or certificates with respect to such insurance (and any
other insurance maintained by the Debtor) (a) shall be endorsed to the Agent's
reasonable satisfaction for the benefit of the Agent (including, without
limitation, by naming the Agent as additional insured and loss payee) and (b)
shall state that such insurance policies shall not be canceled without thirty
(30) days' prior written notice thereof by the insurer to the Agent; and
certified copies of such policies or certificates with respect thereto shall be
deposited with the Agent. If any Debtor shall fail to insure its Inventory and
Equipment in accordance with the preceding sentence, or if any Debtor shall fail
to so endorse and deposit all policies or certificates with respect thereto, the
Agent shall have the right (but shall be under no obligation), upon prior
written notice to any such Debtor, to procure such insurance and such Debtor
agrees to promptly reimburse the Agent for all costs and expenses of procuring
such insurance. The Agent shall, at the time any proceeds of such insurance are
distributed to the Lenders, apply such proceeds in accordance with Section 7.4
hereof except as otherwise provided by the Credit Agreement. Each Debtor assumes
all liability and responsibility in connection with the Collateral acquired by
it and the liability of each Debtor to pay the Obligations shall in no way be
affected or diminished by reason of the fact that such Collateral may be lost,
destroyed, stolen, damaged or for any reason whatsoever unavailable to the
Debtor.

         Section 6.2 Further Actions. Each Debtor will, at its own expense,
make, execute, endorse, acknowledge, file and/or deliver to the Agent from time
to time such lists, descriptions and designations of its Collateral, warehouse
receipts, receipts in the nature of warehouse receipts, bills of lading,
documents of title, vouchers, invoices, schedules, confirmatory assignments,
conveyances, financing statements, transfer endorsements, powers

                                       10
<PAGE>   129
of attorney, certificates, reports and other assurances or instruments and take
such further steps relating to the Collateral and other property or rights
covered by the security interest hereby granted, which the Agent reasonably
requests in order to perfect, preserve or protect its security interest in the
Collateral.

         Section 6.3 Financing Statements. Each Debtor agrees to execute and
deliver to the Agent such financing statements, in form reasonably acceptable to
the Agent, as the Agent may from time to time reasonably request, to establish
and maintain a valid, enforceable, first priority perfected security interest in
the Collateral as provided herein and the other rights and security contemplated
hereby all in accordance with the UCC as enacted in any and all relevant
jurisdictions or any other relevant law. Each Debtor will pay any applicable
filing fees, recordation taxes and related expenses relating to its Collateral.
Each Debtor hereby authorizes the Agent upon the occurrence and during the
continuance of an Event of Default to file any such financing statements without
its signature where permitted by law.


                                    ARTICLE 7

                  REMEDIES UPON OCCURRENCE OF EVENT OF DEFAULT

         Section 7.1 Remedies; Obtaining the Collateral Upon Default. Each
Debtor agrees that upon the occurrence of an Event of Default, the Agent, in
addition to any rights now or hereafter existing under applicable law, shall
have all rights as a secured creditor under the UCC in all relevant
jurisdictions and may:

                  (a) personally, or by agents or attorneys, immediately take
possession of the Collateral or any part thereof, from such Debtor or any other
Person who then has possession of any part thereof, with or without notice or
process of law, and for that purpose may enter upon the Debtor's premises where
any of the Collateral is located and remove the same and use in connection with
such removal any and all services, supplies, aids and other facilities of the
Debtor;

                  (b) instruct the obligor or obligors on any agreement,
instrument or other obligation (including, without limitation, the Receivables
and the Contracts) constituting the Collateral to make any payment required by
the terms of such agreement, instrument or other obligation directly to the
Agent;

                  (c) withdraw all monies, securities and instruments in the
Cash Collateral Account and/or in any other cash collateral account for
application to the Obligations in accordance with Section 7.4 hereof;

                  (d) sell, assign or otherwise liquidate any or all of the
Collateral or any part thereof in accordance with Section 7.2 hereof, or direct
the Debtor to sell, assign or otherwise

                                       11
<PAGE>   130
liquidate any or all of the Collateral or any part thereof, and, in each case,
take possession of the proceeds of any such sale or liquidation;

                  (e) take possession of the Collateral or any part thereof, by
directing the relevant Debtor in writing to deliver the same to the Agent at any
place or places reasonably designated by the Agent, in which event such Debtor
shall at its own expense:

                       (i) forthwith cause the same to be moved to the place or
         places so designated by the Agent and there delivered to the Agent;

                       (ii) store and keep any Collateral so delivered to the
         Agent at such place or places pending further action by the Agent as
         provided in Section 7.2 hereof; and

                       (iii) while the Collateral shall be so stored and kept,
         provide such guards and maintenance services as shall be necessary to
         protect the same and to preserve and maintain them in good condition;
         and

                  (f) license or sublicense, whether on an exclusive or
nonexclusive basis, any Marks, Patents or Copyrights included in the Collateral
for such term and on such conditions and in such manner as the Agent shall in
its reasonable judgment determine;

it being understood that each Debtor's obligation to deliver the Collateral is
of the essence of this Agreement and that, accordingly, upon application to a
court of equity having jurisdiction, the Agent shall be entitled to a decree
requiring specific performance by any such Debtor of said obligation. The
Lenders agree that this Agreement may be enforced only by the action of the
Agent acting upon the instructions of the Majority Lenders and that no other
Lender shall have any right individually to seek to enforce this Agreement or to
realize upon the security to be granted hereby, it being understood and agreed
that such rights and remedies may be exercised by the Agent for the benefit of
the Lenders upon the terms of this Agreement.

         Section 7.2 Remedies: Disposition of the Collateral. Any Collateral
repossessed by the Agent under or pursuant to Section 7.1 hereof and any other
Collateral whether or not so repossessed by the Agent, may be sold, assigned,
leased or otherwise disposed of under one or more contracts or as an entirety,
and without the necessity of gathering at the place of sale the property to be
sold, and in general in such manner, at such time or times, at such place or
places and on such terms as the Agent may, in compliance with any mandatory
requirements of applicable law, determine to be commercially reasonable. Any of
the Collateral may be sold, leased or otherwise disposed of, in the condition in
which the same existed when taken by the Agent or after any overhaul or repair
at the expense of the Debtor which the Agent shall determine to be commercially
reasonable. Any such disposition which shall be a private sale or other private
proceeding permitted by such requirements shall be made upon not less than ten
(10) days' written notice to the Debtor specifying the time at which such
disposition is to be made and the intended sale price or other consideration
therefor, and shall be subject, for

                                       12
<PAGE>   131
the ten (10) days after the giving of such notice, to the right of the Debtor or
any nominee of the Debtor to acquire the Collateral involved at a price or for
such other consideration at least equal to the intended sale price or other
consideration so specified. Any such disposition which shall be a public sale
permitted by such requirements shall be made upon not less than ten (10) days'
written notice to the Debtor specifying the time and place of such sale and, in
the absence of applicable requirements of law, shall be by public auction (which
may, at the Agent's option, be subject to reserve), after publication of notice
of such auction not less than ten (10) days prior thereto in two newspapers in
general circulation in Boston, Massachusetts. To the extent permitted by any
such requirement of law, the Agent may bid for and become the purchaser of the
Collateral or any item thereof offered for sale in accordance with this Section
without accountability to the Debtor. If, under mandatory requirements of
applicable law, the Agent shall be required to make disposition of the
Collateral within a period of time which does not permit the giving of notice to
the Debtor as hereinabove specified, the Agent need give the Debtor only such
notice of disposition as shall be reasonably practicable in view of such
mandatory requirements of applicable law.

         Section 7.3 Waiver of Claims. Except as otherwise provided in this
Agreement, (a) EACH DEBTOR HEREBY WAIVES, TO THE EXTENT PERMITTED BY APPLICABLE
LAW, NOTICE AND JUDICIAL HEARING IN CONNECTION WITH THE AGENT'S TAKING
POSSESSION OR THE AGENT'S DISPOSITION OF ANY OF THE COLLATERAL, INCLUDING,
WITHOUT LIMITATION, ANY AND ALL PRIOR NOTICE AND HEARING FOR ANY PREJUDGMENT
REMEDY OR REMEDIES AND ANY SUCH RIGHT WHICH EACH DEBTOR WOULD OTHERWISE HAVE
UNDER THE CONSTITUTION OR ANY STATUTE OF THE UNITED STATES OR OF ANY STATE, and
(b) each Debtor hereby further waives, to the extent permitted by law:

                       (i) all damages occasioned by such taking of possession
         except any damages which are determined by a final, non-appealable
         court order to have been caused by the Agent's gross negligence or
         willful misconduct; and

                       (ii) all other requirements as to the time, place and
         terms of sale or other requirements with respect to the enforcement of
         the Agent's rights hereunder; and

                  (c) all rights of redemption, appraisement, valuation, stay,
extension or moratorium now or hereafter in force under any applicable law in
order to prevent or delay the enforcement of this Agreement or the absolute sale
of the Collateral or any portion thereof, and each Debtor, for itself and all
who may claim under it, insofar as it or they now or hereafter lawfully may,
hereby waives the benefit of all such laws.

Any sale of, or the grant of options to purchase, or any other realization upon,
any Collateral shall operate to divest all right, title, interest, claim and
demand, either at law or in equity, of the Debtor therein and thereto, and shall
be a perpetual bar both at law and in equity against

                                       13
<PAGE>   132
the Debtor and against any and all Persons claiming or attempting to claim the
Collateral so sold, optioned or realized upon, or any part thereof, from,
through and under the Debtor.

         Section 7.4 Application of Proceeds. All moneys collected by the Agent
upon any sale or other disposition of the Collateral, together with all other
moneys received by the Agent hereunder, shall be applied as provided in Section
10.3 of the Credit Agreement. It is understood and agreed that each Debtor shall
remain liable to the extent of any deficiency between the amount of the proceeds
of the Collateral hereunder and the aggregate amount of the Obligations.

         Section 7.5 Remedies Cumulative. Each and every right, power and remedy
hereby specifically given to the Agent shall be in addition to every other
right, power and remedy specifically given under this Agreement, the other
Lender Agreements or now or hereafter existing at law, in equity or by statute
and each and every right, power and remedy whether specifically herein given or
otherwise existing may be exercised from time to time or simultaneously and as
often and in such order as may be deemed expedient by the Agent. All such
rights, powers and remedies shall be cumulative and the exercise or the
beginning of the exercise of one shall not be deemed a waiver of the right to
exercise any other or others. No delay or omission of the Agent in the exercise
of any such right, power or remedy and no renewal or extension of any of the
Obligations shall impair any such right, power or remedy or shall be construed
to be a waiver of any Default or Event of Default or an acquiescence therein. No
notice to or demand on any Debtor in any case shall entitle it to any other or
further notice or demand in similar or other circumstances or constitute a
waiver of any of the rights of the Agent to any other or further action in any
circumstances without notice or demand. In the event that the Agent shall bring
any suit to enforce any of its rights hereunder and shall be entitled to
judgment, then in such suit the Agent may recover reasonable expenses, including
reasonable attorneys' fees, and the amounts thereof shall be included in such
judgment.

         Section 7.6 Discontinuance of Proceedings. In case the Agent 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 Agent, then and in every such case each Debtor, the Agent and
each holder of any of the Obligations shall be restored to their former
positions and rights hereunder with respect to the Collateral subject to the
security interest created under this Agreement, and all rights, remedies and
powers of the Agent shall continue as if no such proceeding had been instituted.

                    RECEIVABLES; CONTRACT RIGHTS; INSTRUMENTS

         Section 3.1 Additional Representations and Warranties. As of the time

times upon reasonable prior notice to the Debtor. Each Debtor shall affix to
each writing constituting chattel paper, and if the Agent so directs to all
other Receivables and Contracts, as well as books, records and documents of each
Debtor evidencing or pertaining to such Receivables and Contracts, an
appropriate reference, in form and manner satisfactory to the Agent, to the fact
that such chattel paper, Receivables and Contracts have been assigned to the
Agent and that the Agent has a security interest therein. Upon the occurrence
and during the continuance of an Event of Default, and at the reasonable request
of the Agent, each Debtor shall, at its own cost and expense, deliver all
tangible evidence of its Receivables and Contract Rights (including, without
limitation, all documents evidencing the Receivables and all Contracts and each
specific writing constituting chattel paper) and such books and records to the
Agent or to its representatives (copies of which evidence and books and records

Account, (b) that the Agent may, at its option, directly notify the obligors
with respect to any Receivables and/or under any Contracts to make payments with
respect thereto as provided in preceding clause (a) and (c) that the Agent may
enforce collection of any such Receivables and Contracts and may adjust, settle
or compromise the amount of payment thereof, in the same manner and to the same
extent as such Debtors. Without notice to or assent by the Debtors, upon the
occurrence and during the continuance of an Event of Default, the Agent may
apply any or all amounts then in, or thereafter deposited in, the Cash
Collateral Account which application shall be effected in the manner provided in
Section 7.4 of this Agreement. The reasonable costs and expenses (including
reasonable attorneys' fees) of collection, whether incurred by any Debtor or the
Agent, shall be borne by

                                        5
<PAGE>   144
the Debtors. The Agent shall deliver a copy of each notice referred to in the
preceding clause (b) to the Debtors; provided, that the failure by the Agent to
so notify any Debtor shall not affect the effectiveness of such notice or the
other rights of the Agent created by this Section 3.3.

         Section 3.4 Modification of Terms; Etc. No Debtor may rescind or cancel
any indebtedness evidenced by any Receivable or under any Contract, or modify
any term thereof or make any adjustment with respect thereto in a manner adverse
to the Agent, or extend or renew the same, or compromise or settle any material
dispute, claim, suit or legal proceeding relating thereto in a manner adverse to
the Agent, or sell any Receivable or Contract, or interest therein, without the
prior written consent of the Agent, except in accordance with the Debtor's
reasonable business practices.

         Section 3.5 Collection. Each Debtor shall endeavor, in accordance with
reasonable business practices, to cause to be collected from the account debtor
named in each of its Receivables or obligor under any Contract, as and when due
(including, without limitation, amounts which are delinquent, such amounts to be
collected in accordance with generally accepted lawful collection procedures)
any and all amounts owing under or on account of such Receivable or Contract,
and apply forthwith upon receipt thereof all such amounts as are so collected to
the outstanding balance of such Receivable or under such Contract. The
reasonable costs and expenses (including, without limitation, reasonable
attorneys' fees) of collection, if incurred by any Debtor or the Agent, shall be
borne by the Debtors.

         Section 3.6 Instruments. If any Debtor owns or acquires any Instrument
constituting Collateral, the Debtor will within 10 Business Days notify the
Agent thereof, and upon request by the Agent, will promptly deliver such
Instrument to the Agent appropriately endorsed to the order of the Agent as
further security hereunder.

taken as a whole; and (iv) except

owner of all trademark registrations and applications listed on Exhibit C hereto
for each Debtor and that said registrations are valid and subsisting, and that

the United States Patent and Trademark Office in order to effect an absolute
assignment of all right, title and interest in each Mark, and record the same.

         Section 4.2 Infringements. Each Debtor agrees, promptly upon learning
thereof, to notify the Agent in writing of the name and address of, and to
furnish such pertinent information that may be available with respect to, any

in any material respect any of the Debtor's rights in and to any Mark, or with
respect to any party claiming that the Debtor's use of any Mark violates in any
material respect any property right of that party. Each Debtor further agrees to
prosecute any Person infringing any Mark in accordance with reasonable business
practices.

         Section 4.3 Preservation of Marks. Each Debtor agrees to use its Marks
as required in each of the applicable jurisdictions during the time in which
this Agreement is in effect, sufficiently to preserve such Marks (and any
registrations thereto) as trademarks or service marks under the laws of the
United States and any other applicable law; provided, that, prior to any
Default, no Debtor shall be obligated to preserve any Mark in the event the
Debtor determines, in its reasonable business judgment, that the preservation of
such Mark is no longer desirable in the conduct of its business.

         Section 4.4 Maintenance of Registration. Each Debtor shall, at its own
expense, diligently process all documents required by the Trademark Act of 1946,
15 U.S.C. Sections 1051 et seq. to maintain trademark registrations,
including but not limited to affidavits of use and applications for renewals of
registration in the United States Patent and Trademark Office for all of its
registered Marks pursuant to 15 U.S.C. Sections 1058(a), 1059 and 1065,
and shall pay all fees and disbursements in connection therewith and shall not
abandon any such filing of affidavit of use or any such application of renewal
prior to the exhaustion of all administrative and judicial remedies without
prior written consent of the Agent (which consent shall not be unreasonably
withheld); provided, that, prior to any Default, no Debtor shall be obligated to
maintain any Mark in the event that the Debtor determines, in its reasonable
business judgment, that the maintenance of such Mark is no longer necessary or
desirable in the conduct of its business.

         Section 4.5 Future Registered Marks. If any Mark registration issues
hereafter to any Debtor as a result of any application now or hereafter pending
before the United States Patent and Trademark Office, within sixty (60) days of
receipt of such certificate, such Debtor shall deliver to the Agent a copy of
such certificate, and an assignment for security in such Mark, to the Agent and
at the expense of such Debtor, confirming the assignment for security

                                        7
<PAGE>   146
in such Mark to the Agent hereunder, the form of such security to be
substantially the same as the form hereof or in such other form as may be
reasonably satisfactory to the Agent.

         Section 4.6 Remedies. Upon the occurrence and during the continuance of
an Event of Default, the Agent may take any or all of the following actions: (a)
declare the entire right, title and interest of any Debtor in and to each of the
Marks, together with all trademark rights and rights of protection to the same,
vested in the Agent, for the benefit of the Lenders, in which event such rights,
title and interest shall immediately vest in the Agent, for the benefit of the
Lenders, and the Agent shall be entitled to exercise the power of attorney
referred to in Section 4.1 hereof to execute, cause to be acknowledged and
notarized and to record said absolute assignment with the applicable agency; (b)
take and use or sell the Marks and the goodwill of such Debtor's business
symbolized by the Marks or carry on the business and use the assets of such
Debtor which have been used in connection with the Marks; and (c) direct the
Debtor to refrain, in which event the Debtor shall refrain, from using the Marks
in any manner whatsoever, directly or indirectly, and, if requested by the
Agent, change the Debtor's corporate name to eliminate therefrom any use of any
Mark and execute such other and further documents that the Agent may request to
further confirm this and to transfer ownership of the Marks and registrations
and any pending trademark application in the United States Patent and Trademark
Office to the Agent.

         Section 4.7 Collateral Assignment. In addition to, and not in
limitation of, the grant of the security interest in Article 1 above, each
Debtor hereby grants, assigns, transfers, conveys and sets over to the Agent,
for the benefit of the Lenders, effective upon the occurrence and during the
continuance of an Event of Default, each Debtor's entire right, title and
interest in and to the Marks, the goodwill of the business symbolized by the
Marks and Proceeds. Each Debtor has delivered to the Agent an Assignment of
Trademarks (the "Assignment") and upon the occurrence and during the continuance
of an Event of Default, the Agent is hereby authorized to file such Assignment
with the United States Patent and Trademark Office. Upon payment in full of all
Obligations, the Agent will assign the Marks to the Debtor.


                                    ARTICLE 5

                          SPECIAL PROVISIONS CONCERNING
                      PATENTS, COPYRIGHTS AND TRADE SECRETS

         Section 5.1 Additional Representations and Warranties. Except as set
forth on Schedule 5.16 to the Credit Agreement, each Debtor represents and
warrants that, as of the date hereof, it is the true and lawful owner of all
rights in (a) all Trade Secrets and Proprietary Information necessary to operate
its business, (b) the Patents listed on Exhibit D hereto for each Debtor, said
Patents constituting all the patents and applications for patents that each
Debtor owns on the date hereof and (c) the Copyrights listed on Exhibit E hereto
for each Debtor, said Copyrights constituting all registrations of copyrights
and applications for

                                        8
<PAGE>   147
copyright registrations that each such Debtor owns on the date hereof. Each
Debtor further warrants that it has no knowledge of any third party claim that
any aspect of its present or contemplated business operations infringe or will
infringe any patent or any copyright or that it has misappropriated any Trade
Secret or Proprietary Information, in each case in any respect which could
reasonably be expected to have a Material Adverse Effect on such Debtor and its
Subsidiaries taken as a whole. Each Debtor hereby grants to the Agent an
absolute power of attorney to sign, upon the occurrence and during the
continuance of an Event of Default, any document which may be required by the
United States Patent and Trademark Office or the United States Copyright Office
in order to effect an absolute assignment of all right, title and interest in
each Patent and Copyright, and to record the same.

         Section 5.2 Infringements. Each Debtor agrees, promptly upon learning
thereof, to furnish to the Agent in writing all pertinent information available
to such Debtor with respect to any infringement, contributing infringement or
active inducement to infringe in any material respect any Patent or Copyright or
to any claim that the practice of any Patent or the use of any Copyright
violates in any material respect any property right of a third party, or with
respect to any misappropriation of any Trade Secret right or any claim that
practice of any material Trade Secret right violates in any material respect any
property right of a third party. Each Debtor further agrees, to the extent
consistent with reasonable business practices, to prosecute any Person
infringing any Patent or Copyright or any Person misappropriating any Trade
Secret right.

         Section 5.3 Maintenance of Patents. At its own expense, each Debtor
shall make timely payment of all post-issuance fees required pursuant to 35
U.S.C. Section 41 to maintain in force rights under each Patent, absent prior
written consent of the Agent; provided, that no Debtor shall be obligated to
maintain any Patent in the event the Debtor determines, in its reasonable
business judgment, that the maintenance of such Patent is no longer necessary or
desirable in the conduct of its business.

         Section 5.4 Prosecution of Patent Application. At its own expense, such
Debtor shall diligently prosecute all applications for Patents for such Debtor
and shall not abandon any such application prior to exhaustion of all
administrative and judicial remedies, absent written consent of the Agent (which
consent shall not be unreasonably withheld); provided, that no Debtor shall be
obligated to prosecute any application in the event the Debtor determines, in
its reasonable business judgment, that the prosecuting of such application is no
longer necessary or desirable in the conduct of its business.

         Section 5.5 Other Patents and Copyrights. Within sixty (60) days of the
acquisition or issuance of a Patent, registration of a Copyright, or acquisition
of a registered copyright, the Debtor shall deliver to the Agent a copy of said
Copyright or certificate or registration of said patents, as the case may be,
with an assignment for security as to such Patent or Copyright, as the case may
be, to the Agent and at the expense of the Debtor, confirming the assignment for
security, the form of such assignment for security to be substantially the same
as the form hereof or in such other form as may be reasonably satisfactory to
the Agent.

<PAGE>   148
         Section 5.6 Remedies. Upon the occurrence and during the continuance of
an Event of Default, the Agent may take any or all of the following actions: (a)
declare the entire right, title, and interest of any Debtor in each of the
Patents and Copyrights vested in the Agent, for the benefit of the Lenders, in
which event such right, title, and interest shall immediately vest in the Agent,
for the benefit of the Lenders, and in which case the Agent shall be entitled to
exercise the power of attorney referred to in Section 5.1 hereof to execute,
cause to be acknowledged and notarized and to record said absolute assignment
with the applicable agency; (b) take and practice, use or sell the Patents and
Copyrights; and (c) direct such Debtor to refrain, in which event such Debtor
shall refrain, from practicing the Patents and using the Copyrights, directly or
indirectly, and such Debtor shall execute such other and further documents as
the Agent may request further to confirm this and to transfer ownership of the
Patents and Copyrights to the Agent, for the benefit of the Lenders.


                                    ARTICLE 6

                      PROVISIONS CONCERNING ALL COLLATERAL

         Section 6.1 Protection of Agent's Security. Each Debtor will at all
times keep its Inventory and Equipment insured in favor of the Agent, at each
such Debtor's own expense to the extent and in the manner provided in the Lender
Agreements; all policies or certificates with respect to such insurance (and any
other insurance maintained by the Debtor) (a) shall be endorsed to the Agent's
reasonable satisfaction for the benefit of the Agent (including, without
limitation, by naming the Agent as additional insured and loss payee) and (b)
shall state that such insurance policies shall not be canceled without thirty
(30) days' prior written notice thereof by the insurer to the Agent; and
certified copies of such policies or certificates with respect thereto shall be
deposited with the Agent. If any Debtor shall fail to insure its Inventory and
Equipment in accordance with the preceding sentence, or if any Debtor shall fail
to so endorse and deposit all policies or certificates with respect thereto, the
Agent shall have the right (but shall be under no obligation), upon prior
written notice to any such Debtor, to procure such insurance and such Debtor
agrees to promptly reimburse the Agent for all costs and expenses of procuring
such insurance. The Agent shall, at the time any proceeds of such insurance are
distributed to the Lenders, apply such proceeds in accordance with Section 7.4
hereof except as otherwise provided by the Credit Agreement. Each Debtor assumes
all liability and responsibility in connection with the Collateral acquired by
it and the liability of each Debtor to pay the Obligations shall in no way be
affected or diminished by reason of the fact that such Collateral may be lost,
destroyed, stolen, damaged or for any reason whatsoever unavailable to the
Debtor.

         Section 6.2 Further Actions. Each Debtor will, at its own expense,
make, execute, endorse, acknowledge, file and/or deliver to the Agent from time
to time such lists, descriptions and designations of its Collateral, warehouse
receipts, receipts in the nature of warehouse receipts, bills of lading,
documents of title, vouchers, invoices, schedules, confirmatory assignments,
conveyances, financing statements, transfer endorsements, powers

                                       10
<PAGE>   149
of attorney, certificates, reports and other assurances or instruments and take
such further steps relating to the Collateral and other property or rights
covered by the security interest hereby granted, which the Agent reasonably
requests in order to perfect, preserve or protect its security interest in the
Collateral.

         Section 6.3 Financing Statements. Each Debtor agrees to execute and
deliver to the Agent such financing statements, in form reasonably acceptable to
the Agent, as the Agent may from time to time reasonably request, to establish
and maintain a valid, enforceable, first priority perfected security interest in
the Collateral as provided herein and the other rights and security contemplated
hereby all in accordance with the UCC as enacted in any and all relevant
jurisdictions or any other relevant law. Each Debtor will pay any applicable
filing fees, recordation taxes and related expenses relating to its Collateral.
Each Debtor hereby authorizes the Agent upon the occurrence and during the
continuance of an Event of Default to file any such financing statements without
its signature where permitted by law.


                                    ARTICLE 7

                  REMEDIES UPON OCCURRENCE OF EVENT OF DEFAULT

         Section 7.1 Remedies; Obtaining the Collateral Upon Default. Each
Debtor agrees that upon the occurrence of an Event of Default, the Agent, in
addition to any rights now or hereafter existing under applicable law, shall
have all rights as a secured creditor under the UCC in all relevant
jurisdictions and may:

                  (a) personally, or by agents or attorneys, immediately take
possession of the Collateral or any part thereof, from such Debtor or any other
Person who then has possession of any part thereof, with or without notice or
process of law, and for that purpose may enter upon the Debtor's premises where
any of the Collateral is located and remove the same and use in connection with
such removal any and all services, supplies, aids and other facilities of the
Debtor;

                  (b) instruct the obligor or obligors on any agreement,
instrument or other obligation (including, without limitation, the Receivables
and the Contracts) constituting the Collateral to make any payment required by
the terms of such agreement, instrument or other obligation directly to the
Agent;

                  (c) withdraw all monies, securities and instruments in the
Cash Collateral Account and/or in any other cash collateral account for
application to the Obligations in accordance with Section 7.4 hereof;

                  (d) sell, assign or otherwise liquidate any or all of the
Collateral or any part thereof in accordance with Section 7.2 hereof, or direct
the Debtor to sell, assign or otherwise

                                       11
<PAGE>   150
liquidate any or all of the Collateral or any part thereof, and, in each case,
take possession of the proceeds of any such sale or liquidation;

         (e) take possession of the Collateral or any part thereof, by directing
the relevant Debtor in writing to deliver the same to the Agent at any place or
places reasonably designated by the Agent, in which event such Debtor shall at
its own expense:

                  (i) forthwith cause the same to be moved to the place or
         places so designated by the Agent and there delivered to the Agent;

                  (ii) store and keep any Collateral so delivered to the Agent
         at such place or places pending further action by the Agent as provided
         in Section 7.2 hereof; and

                  (iii) while the Collateral shall be so stored and kept,
         provide such guards and maintenance services as shall be necessary to
         protect the same and to preserve and maintain them in good condition;
         and

         (f) license or sublicense, whether on an exclusive or nonexclusive
basis, any Marks, Patents or Copyrights included in the Collateral for such term
and on such conditions and in such manner as the Agent shall in its reasonable
judgment determine;

it being understood that each Debtor's obligation to deliver the Collateral is
of the essence of this Agreement and that, accordingly, upon application to a
court of equity having jurisdiction, the Agent shall be entitled to a decree
requiring specific performance by any such Debtor of said obligation. The
Lenders agree that this Agreement may be enforced only by the action of the
Agent acting upon the instructions of the Majority Lenders and that no other
Lender shall have any right individually to seek to enforce this Agreement or to
realize upon the security to be granted hereby, it being understood and agreed
that such rights and remedies may be exercised by the Agent for the benefit of
the Lenders upon the terms of this Agreement.

         Section 7.2 Remedies: Disposition of the Collateral. Any Collateral
repossessed by the Agent under or pursuant to Section 7.1 hereof and any other
Collateral whether or not so repossessed by the Agent, may be sold, assigned,
leased or otherwise disposed of under one or more contracts or as an entirety,
and without the necessity of gathering at the place of sale the property to be
sold, and in general in such manner, at such time or times, at such place or
places and on such terms as the Agent may, in compliance with any mandatory
requirements of applicable law, determine to be commercially reasonable. Any of
the Collateral may be sold, leased or otherwise disposed of, in the condition in
which the same existed when taken by the Agent or after any overhaul or repair
at the expense of the Debtor which the Agent shall determine to be commercially
reasonable. Any such disposition which shall be a private sale or other private
proceeding permitted by such requirements shall be made upon not less than ten
(10) days' written notice to the Debtor specifying the time at which such
disposition is to be made and the intended sale price or other consideration
therefor, and shall be subject, for

                                       12
<PAGE>   151
the ten (10) days after the giving of such notice, to the right of the Debtor or
any nominee of the Debtor to acquire the Collateral involved at a price or for
such other consideration at least equal to the intended sale price or other
consideration so specified. Any such disposition which shall be a public sale
permitted by such requirements shall be made upon not less than ten (10) days'
written notice to the Debtor specifying the time and place of such sale and, in
the absence of applicable requirements of law, shall be by public auction (which
may, at the Agent's option, be subject to reserve), after publication of notice
of such auction not less than ten (10) days prior thereto in two newspapers in
general circulation in Boston, Massachusetts. To the extent permitted by any
such requirement of law, the Agent may bid for and become the purchaser of the
Collateral or any item thereof offered for sale in accordance with this Section
without accountability to the Debtor. If, under mandatory requirements of
applicable law, the Agent shall be required to make disposition of the
Collateral within a period of time which does not permit the giving of notice to
the Debtor as hereinabove specified, the Agent need give the Debtor only such
notice of disposition as shall be reasonably practicable in view of such
mandatory requirements of applicable law.

         Section 7.3 Waiver of Claims. Except as otherwise provided in this
Agreement, (a) EACH DEBTOR HEREBY WAIVES, TO THE EXTENT PERMITTED BY APPLICABLE
LAW, NOTICE AND JUDICIAL HEARING IN CONNECTION WITH THE AGENT'S TAKING
POSSESSION OR THE AGENT'S DISPOSITION OF ANY OF THE COLLATERAL, INCLUDING,
WITHOUT LIMITATION, ANY AND ALL PRIOR NOTICE AND HEARING FOR ANY PREJUDGMENT
REMEDY OR REMEDIES AND ANY SUCH RIGHT WHICH EACH DEBTOR WOULD OTHERWISE HAVE
UNDER THE CONSTITUTION OR ANY STATUTE OF THE UNITED STATES OR OF ANY STATE, and
(b) each Debtor hereby further waives, to the extent permitted by law:

                  (i) all damages occasioned by such taking of possession except
         any damages which are determined by a final, non-appealable court order
         to have been caused by the Agent's gross negligence or willful
         misconduct; and

                  (ii) all other requirements as to the time, place and terms of
         sale or other requirements with respect to the enforcement of the
         Agent's rights hereunder; and

                  (c) all rights of redemption, appraisement, valuation, stay,
extension or moratorium now or hereafter in force under any applicable law in
order to prevent or delay the enforcement of this Agreement or the absolute sale
of the Collateral or any portion thereof, and each Debtor, for itself and all
who may claim under it, insofar as it or they now or hereafter lawfully may,
hereby waives the benefit of all such laws.

Any sale of, or the grant of options to purchase, or any other realization upon,
any Collateral shall operate to divest all right, title, interest, claim and
demand, either at law or in equity, of the Debtor therein and thereto, and shall
be a perpetual bar both at law and in equity against

                                       13
<PAGE>   152
the Debtor and against any and all Persons claiming or attempting to claim the
Collateral so sold, optioned or realized upon, or any part thereof, from,
through and under the Debtor.

         Section 7.4 Application of Proceeds. All moneys collected by the Agent
upon any sale or other disposition of the Collateral, together with all other
moneys received by the Agent hereunder, shall be applied as provided in Section
10.3 of the Credit Agreement. It is understood and agreed that each Debtor shall
remain liable to the extent of any deficiency between the amount of the proceeds
of the Collateral hereunder and the aggregate amount of the Obligations.

         Section 7.5 Remedies Cumulative. Each and every right, power and remedy
hereby specifically given to the Agent shall be in addition to every other
right, power and remedy specifically given under this Agreement, the other
Lender Agreements or now or hereafter existing at law, in equity or by statute
and each and every right, power and remedy whether specifically herein given or
otherwise existing may be exercised from time to time or simultaneously and as
often and in such order as may be deemed expedient by the Agent. All such
rights, powers and remedies shall be cumulative and the exercise or the
beginning of the exercise of one shall not be deemed a waiver of the right to
exercise any other or others. No delay or omission of the Agent in the exercise
of any such right, power or remedy and no renewal or extension of any of the
Obligations shall impair any such right, power or remedy or shall be construed
to be a waiver of any Default or Event of Default or an acquiescence therein. No
notice to or demand on any Debtor in any case shall entitle it to any other or
further notice or demand in similar or other circumstances or constitute a
waiver of any of the rights of the Agent to any other or further action in any
circumstances without notice or demand. In the event that the Agent shall bring
any suit to enforce any of its rights hereunder and shall be entitled to
judgment, then in such suit the Agent may recover reasonable expenses, including
reasonable attorneys' fees, and the amounts thereof shall be included in such
judgment.

         Section 7.6 Discontinuance of Proceedings. In case the Agent 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 Agent, then and in every such case each Debtor, the Agent and
each holder of any of the Obligations shall be restored to their former
positions and rights hereunder with respect to the Collateral subject to the
security interest created under this Agreement, and all rights, remedies and
powers of the Agent shall continue as if no such proceeding had been instituted.

         9.  The execution and delivery by the Subsidiary of the Documents to

applicable and material to the Subsidiary or any of its properties.

         10. The execution and delivery of the Documents to which it is a party

         13. The execution and delivery by the Parent of the Documents to which
it is a party and the performance by the Parent of such Documents (other than
the Financing Statements, the stock powers and the stock certificates) will not
violate (i) the Parent's existing Certificate of Incorporation or By-laws, (ii)
any provision of existing law applicable and material to the Parent or any of
its properties or (iii) any of the Material Agreements.

         14. The execution and delivery of the Documents to which it is a party

         15. The provisions of the Guarantors Security Agreement are sufficient
to create in favor of the Agent a valid, binding and enforceable security
interest in all right, title and interest of the Parent in such of the

outstanding capital stock of the Company and all of the outstanding beneficial
interests of the Business Trust, and upon delivery to the Agent of the stock
certificates for one hundred (100) shares of the stock of the Company and one
hundred (100) shares of the beneficial interests of the Business Trust, and the
stock powers endorsed to the Agent or in blank or in registered form issued to
the Agent, the Agent will have a perfected security interest in all the right,
title and interest of the Parent in the Company and Business Trust shares
pledged.

         17. Based upon the Business Trust Legal Existence Certificate referred
to in item (e)(ii) above, the Business Trust is (as of the date of such

in the Commonwealth of Massachusetts. The Business Trust has adequate power and
authority as a Massachusetts business trust to own its properties, to enter into
and perform the Documents to which it is a party and, to our knowledge, to
conduct its business as currently conducted.

         18. The execution and delivery of the Documents to which it is a party

         20. The execution and delivery of the Documents to which it is a party
by the Business Trust, and the consummation by the Business Trust of the
transactions contemplated thereby, do not to our knowledge require under
existing law any consent or approval of or filings with any federal or state
governmental body or regulatory authority other than as set forth in paragraph
number 21 below.

         21. The provisions of the Guarantors Security Agreement are sufficient
to create in favor of the Agent a valid, binding and enforceable security
interest in all right, title and interest of the Business Trust in such of the
Collateral described therein in which a security interest may be created under
Article 9 of the Massachusetts Uniform Commercial Code (the "Code"). Upon the
due execution and filing of the Financing Statement executed by the Business
Trust, noted to be filed in the office of the Secretary of State of the
Commonwealth of Massachusetts, the Agent will have a perfected security interest
in all right, title and interest of the Business Trust in such of the Collateral

         Our opinions set forth herein are subject to the following limitations
and qualifications:

         A.       In our examination and in rendering this opinion letter, we
                  have assumed the genuineness of all signatures, the legal
                  capacity of natural persons, the power and authority of all
                  natural persons (other than officers or Trustees of the Loan
                  Parties acting in such capacities), the authenticity and
                  completeness of all documents submitted to us as originals,
                  the conformity to original documents of all documents
                  submitted to us as copies and the authenticity of the
                  originals of such latter documents.

         B.       In rendering this opinion letter, we have also assumed that
                  the Agent is a "Agent subject to control, regulation or
                  examination by any state or federal regulatory agency" within
                  the meaning of M.G.L. c. 271 Section 49(e). We have also
                  assumed that each person or entity (other than the Loan
                  Parties) which is a party to any Document (a "Signatory") has
                  all requisite power and authority and has taken all necessary
                  corporate or other action to authorize it to execute, deliver
                  and perform such of the Documents and other related documents
                  as

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


                  may be executed in connection therewith to which it is a party
                  and to effect the transactions contemplated thereby; that such
                  Signatory has executed and delivered the Documents and such
                  other related documents; that the same constitute legal, valid
                  and binding obligations of such Signatory enforceable against
                  it; and that the consideration to be received by the Borrower
                  pursuant to the Amended and Restated Credit Agreement has been
                  or will be delivered to or for the benefit of such Loan Party,
                  respectively, on the date hereof. Our opinion does not take
                  account of, and we express no opinion with respect to, (i) any
                  requirement of law which may be applicable to the Loan Parties
                  or any Signatory by reason of the legal or regulatory status
                  of such Signatory or by reason of any other facts particularly
                  pertaining to such Signatory, or (ii) any approval or consent
                  arising out of any contract or agreement (other than the
                  Documents) to which any Signatory is a party or by which it is
                  bound.

         C.       Our opinions set forth herein as to the validity, binding
                  effect and enforceability of the Documents and the perfection
                  of the security interests granted by the Loan Parties are
                  specifically qualified to the extent that the validity,
                  binding effect or enforceability of any obligations of the
                  Loan Parties under any of the Documents, the availability or
                  enforceability of any of the remedies provided therein or such
                  perfection may be subject to or limited by (i) applicable
                  bankruptcy, insolvency, reorganization, fraudulent conveyance,
                  moratorium and other statutory or decisional laws, heretofore
                  or hereafter enacted or in effect, affecting the rights of
                  creditors generally, (ii) the exercise of judicial or
                  administrative discretion, (iii) the application by courts of
                  competent jurisdiction of laws containing provisions
                  determined to have a paramount public interest, (iv) the
                  Agent's implied duty of good faith and, with respect to any of
                  the Agent's rights concerning collateral security, its
                  overriding duty to act, as to every aspect of any disposition
                  thereof or realization thereon, in a commercially reasonable
                  manner, and (v) the availability or enforceability of
                  particular remedies, of exculpatory provisions and of waivers
                  contained in the Documents, which particular remedies,
                  exculpatory provisions and waivers of rights may be limited by
                  equitable principles or applicable laws, rules, regulations,
                  court decisions and constitutional requirements. In connection
                  with our opinions in Paragraphs 12 and 18 as to the validity,
                  binding effect and enforceability of the Documents entered
                  into by the Guarantors, we have assumed and have relied in
                  part on our understanding that the Agent is relying on and
                  would not extend the credit to the Borrowers were it not for
                  the execution and delivery of such Documents by the
                  Guarantors.

         D.       No opinion is expressed herein with respect to title to
                  property (real or personal), the priority of any security
                  interest or lien, the applicability of or

                  compliance with zoning by-laws, subdivision control laws,
                  environmental laws or state or federal securities laws, or the
                  enforceability of provisions of the Documents to the extent
                  such enforceability is predicated upon any of the foregoing.

         E.       In rendering this opinion letter, we have assumed that each of
                  the Loan Parties has rights in its respective Collateral
                  described in the Security Agreement and the Guarantors
                  Security Agreement.

         F.       This opinion letter is limited to the legal matters explicitly
                  addressed herein and does not extend, by implication or
                  otherwise, to any other matter. Without limiting the
                  generality of the foregoing, no opinion is expressed herein
                  with respect to any state or federal anti-trust law or, except
                  as provided in paragraph 22 above, as to whether the Revolving
                  Loans to be made pursuant to the Agreement could be determined
                  to be usurious under any state or federal law. This opinion is
                  not subject to, and shall not be governed by or interpreted in
                  accordance with, the Third-Party Legal Opinion Report
                  (including the Legal Opinion Accord and the "guidelines" set
                  forth therein) of the ABA Section of Business Law (1991).

         G.       We are not passing upon and do not assume any responsibility
                  for the accuracy, sufficiency, completeness or fairness of any
                  statements, representations, warranties, descriptions,
                  information or financial data supplied to the Agent with
                  respect to the Documents, or the transactions contemplated
                  thereby, or for the fairness of such transactions themselves,
                  and we make no representation that we have independently
                  verified the accuracy, sufficiency, completeness or fairness
                  of any of the foregoing.

         H.       With respect to references herein to "our knowledge" or words
                  of similar import, such references mean the knowledge of the
                  following attorneys presently employed by Goulston & Storrs:
                  Kitt Sawitsky, Jeffrey S. Wolfson, Timothy B. Bancroft, Daniel
                  R. Avery, Connie L. Kolb and Shannon M. Quinlan. Nothing has
                  come to our attention which has caused us to believe that the
                  statements made herein "to our knowledge" are untrue or
                  incorrect. However, we have not made any independent review or
                  investigation of any factual matter contained in any written
                  material reviewed or provided orally by any representative of
                  the Loan Parties.

         I.       All opinions rendered herein are limited to the existing laws
                  of the Commonwealth of Massachusetts as applied by courts
                  located in Massachusetts, the existing General Corporation Law
                  of the State of Delaware and existing laws of the United
                  States of America, all as in effect on the date

                  hereof, and we express no opinion as to choice of laws or as
                  to the laws of any other jurisdiction.

         J.       Our opinions in Paragraphs 3, 9, 13 and 19 as to no violation
                  of existing law are based upon a review of those statutes,
                  rules and regulations which, in our experience, are normally
                  applicable to transactions of the type contemplated by the
                  Documents. Our opinions in Paragraphs 4, 14 and 20 relate only
                  to consents and approvals and filings and registrations which
                  in our experience are normally applicable to the transactions
                  of the type contemplated by the Documents.

         This opinion letter is furnished to you exclusively for the purpose of
satisfying the conditions set forth in Section 3.1(m) of the Agreement and shall
not, without our prior written consent, be relied upon by any other person
(except for the Lenders from time to time under the Amended and Restated Credit
Agreement) or used for any other purpose.


                                            Very truly yours,

                  (b) "subordinate and junior in right of payments" means that:

                           (i) no part of the Subordinated Obligations shall 
         have any claim to the assets of a Borrower on a parity with or prior to
         the claim of the Senior Obligations;

                           (ii) unless and until the Senior Obligations have
         been paid in full and the Senior Lenders' commitments to make loans
         under the Senior Credit Agreement have been terminated, without the
         express prior written consent of the Senior Lenders, the Subordinated
         Lender will not take, demand, or receive from a Borrower, and a
         Borrower will not make, give or permit, directly or indirectly, by
         set-off, redemption, purchase or in any other manner, any payment of or
         security for the whole or any part of the Subordinated Obligations,
         including, without limitation, any letter of credit or similar credit
         support facility to support payment of the Subordinated Obligations;
         notwithstanding the foregoing, at any time, except during a Blockage
         Period, a 



                                       4
<PAGE>   190

         Borrower may make, and the Subordinated Lender may receive, payments on
         account of principal and interest on the Subordinated Loans;

                           (iii) unless and until the Senior Obligations have
         been paid in full and the Senior Lenders' commitments to make loans
         under the Senior Credit Agreement have been terminated, the
         Subordinated Lender will not commence or participate in any suit or
         action to enforce payment of any part or all of the Subordinated
         Obligations;

                           (iv) none of the provisions of subsections 2(b)(iii)
         or (iv) above or elsewhere in this Agreement shall in any way derogate
         from or diminish the absolute subordination provided under items
         2(b)(i) and (ii) above or under Section 3 below.

                  (c) Upon the termination of any Blockage Period, the
Subordinated Lender's rights to receive principal and interest payments as
provided in subsection 2(b)(ii) above shall be reinstated, and a Borrower may
resume making such payments to the Subordinated Lender to the extent provided in
such subsection 2(b)(ii).

                  (d) The Agent shall be entitled to deliver a separate Blockage
Notice with respect to any or all Events of Default and each such Blockage
Notice shall be effective as provided in this Agreement.

                  (e) A Blockage Period shall be effective without the delivery
of a Blockage Notice if (i) the events which would have been set forth in the
Blockage Notice have occurred and (ii) such Blockage Notice may not be given
because of the automatic stay under 11 U.S.C. 362 or any successor statute, or
the Subordinated Lender has actual notice of an Event of Default.

                  (f) The expressions "prior payment in full," "payment in
full," "paid in full" and any other similar terms or phrases when used herein
with respect to the Senior Obligations shall mean the payment in full, in
immediately available funds, of all of the Senior Obligations.

                  (g) The Subordinated Lender hereby represents and warrant that
as of the date hereof, the Borrowers have no obligations to the Subordinated
Lender.

         3.        Additional Provisions Concerning Subordination.

                  (a) The Subordinated Lender and the Borrowers agree that upon
the occurrence of any Insolvency Event:

                           (i) all Senior Obligations shall be paid in full
         before any payment or distribution (other than a distribution of
         securities which are subordinate to the payment of all Senior
         Obligations then outstanding) is made with respect to the Subordinated
         Obligations; and
                                        5

<PAGE>   191

                           (ii) any payment or distribution of assets of a 
         Borrower, whether in cash, property or securities (other than a
         distribution of securities which are subordinate to the payment of all
         Senior Obligations then outstanding), to which the Subordinated Lender
         would be entitled except for the provisions hereof, shall be paid or
         delivered by such Borrower, or any receiver, trustee in bankruptcy,
         liquidating trustee, disbursing agent or other Person making such
         payment or distribution, directly to the Agent, to the extent necessary
         to pay in full all Senior Obligations, before any payment or
         distribution shall be made to the Subordinated Lender.

                  (b) The Subordinated Lender will not commence or join with any
other creditor or creditors of a Borrower in commencing any bankruptcy,
reorganization or insolvency proceedings against a Borrower. At any meeting of
creditors of a Borrower or in the event of any proceeding, voluntary or
involuntary, for the distribution, division or application of all or part of the
assets of a Borrower or the proceeds thereof, whether such proceeding be for the
liquidation, dissolution or winding up of a Borrower or its business, a
receivership, insolvency or bankruptcy proceeding, an assignment for the benefit
of creditors or a proceeding by or against a Borrower for relief under any
bankruptcy, reorganization or insolvency law or any law relating to the relief
of debtors, readjustment of indebtedness, reorganization, arrangement,
composition or extension or otherwise, if all Senior Obligations have not been
paid in full at the time, the Agent is hereby irrevocably authorized at any such
meeting or in any such proceeding:

                           (i) To enforce claims comprising Subordinated
         Obligations either in its own name or the name or names the
         Subordinated Lender, by proof of debt, proof of claim, suit or
         otherwise;

                           (ii) To collect any assets of a Borrower distributed,
         divided or applied by way of dividend or payment, or any such
         securities issued, on account of Subordinated Obligations and apply the
         same, or the proceeds of any realization upon the same that the Agent
         in its discretion elects to effect, to Senior Obligations until all
         Senior Obligations shall have been paid in full, rendering any surplus
         to the Subordinated Lender, pro rata;

                           (iii) To vote claims comprising Subordinated
         Obligations to accept or reject any plan of partial or complete
         liquidation, reorganization, arrangement, composition, extension or
         otherwise; and

                           (iv) To take generally any action in connection with
         any such meeting or proceeding which the Subordinated Lender might
         otherwise take.

                  (c) If any payment from a Borrower shall be collected or
received by the Subordinated Lender in respect of the Subordinated Obligations,
except payments permitted to be made at the time of payment as provided in this
Agreement, the Subordinated Lender forthwith shall deliver the same to the
Agent, in the form received, duly endorsed to the 



                                       6
<PAGE>   192

Agent, if required, to be applied to the payment or prepayment of the Senior
Obligations until the Senior Obligations are paid in full. Until so delivered,
such payment or distribution shall be held in trust by the Subordinated Lender
as the property of the Agent, segregated from other funds and property held by
the Subordinated Lender. Until the Senior Obligations are paid in full, the
Subordinated Lender shall not have any right of subrogation, reimbursement,
restitution, contribution or indemnity whatsoever from any assets of a Borrower
or any guarantor or provider of collateral security for the Senior Obligations.

                  4. Legend. The Subordinated Lender shall cause a conspicuous
legend to be placed on each Subordinated Note to the following effect:

                  "This Note, and the indebtedness evidenced hereby, is
         subordinate and junior in right of payment in the manner and to the
         extent set forth in an agreement (the "Subordination Agreement") dated
         as of July 20, 1998 originally made by the maker and payee of this Note
         in favor of the Senior Lenders to all indebtedness at any time owed by
         the maker of this Note to such Bank (or to its successor and assigns or
         subsequent holder of "Senior Obligations" as defined in the
         Subordination Agreement), and each holder of this Note, by its
         acceptance hereof, shall be bound by the Subordination Agreement, and
         this Note may be sold or otherwise transferred only in compliance with
         the conditions specified in the Subordination Agreement."

         5. Liens. The Subordinated Lender shall not have or claim any security
interest, lien, claim, right or other encumbrance in or on any property of a
Borrower on account of the Subordinated Obligations. The Subordinated Lender
hereby agrees, upon request of the Senior Lender at any time and from time to
time, to execute such other documents or instruments as may be requested by the
Agent further to evidence of public record or otherwise the senior priority of
the Senior Obligations as contemplated by this Agreement, and to execute a
subordination agreement on similar terms in favor of any successors or assigns
of the Agent or other lender extending credit to a Borrower in exchange or
replacement of the Senior Obligations.

         6. Consent of Subordinated Lender.

                  (a) The Subordinated Lender consents that, without the
necessity of any reservation of rights and without notice to or further assent:

                           (i) any demand for payment of any Senior Obligations
         made by the Agent or the Senior Lenders may be rescinded in whole or in
         part by the Agent or the Senior Lenders, and any Senior Obligation may
         be continued, and the Senior Obligations, or the liability of a
         Borrower or any guarantor or any other party upon or for any part
         thereof, or any collateral security or guarantee therefor or right of
         offset with respect thereto, or any obligation or liability of a
         Borrower or any other party under the Senior Credit Agreement or any
         other agreement, may, from time to time, in 

                                       7
<PAGE>   193

         whole or in part, be renewed, extended, modified, accelerated,
         compromised, waived, surrendered, or released by the Agent or the
         Senior Lenders; and

                           (ii) the Senior Credit Agreement, the Senior Notes,
         any other Senior Loan Document and the Senior Obligations may be
         amended, modified, supplemented or terminated, in whole or in part, as
         the Agent or the Senior Lenders may deem advisable from time to time,
         and any collateral security at any time held by the Agent or the Senior
         Lenders for the payment of any of the Senior Obligations may be sold,
         exchanged, waived, surrendered or released,

in each case all without notice to or further assent by the Subordinated Lender,
which will remain bound under this Agreement, and all without impairing,
abridging, releasing or affecting the subordination provided for herein.

                  (b) The Subordinated Lender waives any and all notice of the
creation, renewal, extension or accrual of any of the Senior Obligations and
notice of or proof of reliance by the Agent or the Senior Lenders upon this
Agreement. The Senior Obligations, and any of them, shall be deemed conclusively
to have been created, contracted or incurred in reliance upon this Agreement,
and all dealings between a Borrower and the Agent or the Senior Lenders shall be
deemed to have been consummated in reliance upon this Agreement. The
Subordinated Lender acknowledges and agrees that the Agent and the Senior
Lenders have relied upon the subordination provided for herein in entering into
the Senior Credit Agreement and in making funds available to a Borrower
thereunder. The Subordinated Lender waives notice of or proof of reliance on
this Agreement and protest, demand for payment and notice of default.

         7. Senior Obligations Unconditional. All rights and interests of the
Agent and the Senior Lenders hereunder, and all agreements and obligations of
the Subordinated Lender and the Borrowers hereunder, shall remain in full force
and effect irrespective of:

                  (a) any lack of validity or enforceability of any Senior
         Security Documents or any other Senior Loan Documents;

                  (b) any change in the time, manner or place of payment of, or
         in any other term of, all or any of the Senior Obligations, or any
         amendment or waiver or other modification, whether by course of conduct
         or otherwise, of the terms of the Senior Credit Agreement or any other
         Senior Security Document;

                  (c) any exchange, release or nonperfection of any security
         interest in any Collateral, or any release, amendment, waiver or other
         modification, whether in writing or by course of conduct or otherwise,
         of all or any of the Senior Obligations or any guarantee thereof, or



                                       8
<PAGE>   194

                  (d) any other circumstances which otherwise might constitute a
         defense available to, or a discharge of, a Borrower in respect of the
         Senior Obligations, or of either any Subordinated Lender or a Borrower
         in respect of this Agreement.

         8. Waiver of Claims. To the maximum extent permitted by law, the
Subordinated Lender waives any claim it might have against the Agent or the
Senior Lenders with respect to, or arising out of, any action or failure to act
or any error of judgment, negligence, or mistake or oversight whatsoever on the
part of the Agent or the Senior Lenders or their respective directors, officers,
employees or agents with respect to any exercise of rights or remedies under the
Senior Loan Documents or any transaction relating to the Collateral. Neither the
Agent or the Senior Lenders nor any of their directors, officers, employees or
agents shall be liable for failure to demand, collect or realize upon any of the
Collateral or for any delay in doing so or shall be under any obligation to sell
or otherwise dispose of any Collateral upon the request of a Borrower or the
Subordinated Lender or any other Person or to take any other action whatsoever
with regard to the Collateral or any part thereof.

         9. Extension of Senior Obligations. Notwithstanding the foregoing
provisions of this Agreement and any extension by the Agent or the Senior
Lenders of the final maturity date of the Senior Obligations, provided that at
the time no Event of Default under the Senior Loan Documents is continuing, the
Subordinated Lender may receive timely payment of all unpaid principal and
accrued interest on the Subordinated Obligations. In the event an Event of
Default does then exist, the subordination of the Subordinated Obligations under
Section 2(b)(i), (ii) and (iii) and Section 3 shall remain in effect and
unimpaired.

         10. Provisions Applicable After Bankruptcy. The provisions of this
Agreement shall continue in full force and effect notwithstanding the occurrence
of and from and after any "Insolvency Event."

         11. Further Assurances. The Subordinated Lender and the Borrowers, at
their own expense and at any time from time to time, upon the written request of
the Agent or the Senior Lenders will promptly and duly execute and deliver such
further instruments and documents and take such further actions as any Senior
Lender or any successor lender reasonably may request for the purposes of
obtaining or preserving the full benefits of this Agreement and of the rights
and powers herein granted.

         12. Provisions Define Relative Rights. This Agreement is intended
solely for the purpose of defining the relative rights of the Agent or the
Senior Lenders or any successor lenders on the one hand and the Subordinated
Lender and the Borrowers, and no other Person shall have any right, benefit or
other interest under this Agreement.

         13. Powers Coupled With An Interest. All powers, authorizations and
agencies contained in this Agreement are coupled with an interest and are
irrevocable until the Senior Obligations are paid in full and the Senior
Lenders' commitments to make loans to the Borrowers are terminated.

is by and between _____________________________ (the "Vendor") and BankBoston,
N.A., as Agent (the "Senior Agent"), a national banking association whose

         WHEREAS, the Senior Agent and the other lenders from time to time for
whom the Senior Agent acts as agent (the "Senior Lenders") has or will extend
credit to New England Audio Co., Inc. and its subsidiaries (the "Borrowers") for

conditions as the Borrowers, the Senior Agent and the Senior Lenders may agree
to; and

         WHEREAS, in consideration of all such loans, renewals or extensions of
credit which the Senior Agent and the Senior Lenders may make, the Borrowers
will from time to time enter into various credit agreements, guaranties,
security agreements and related documents (as the same may be from time to time
amended, supplemented or modified the "Senior Loan Agreements"); and

         WHEREAS, the Senior Agent and the Vendor, each agree, to the extent of
the security interests each may have in the Borrowers' collateral, that all
rights of the Senior Agent to the security interest and/or liens in and to the
property and/or assets of Borrowers are intended to be senior to all rights of
the Vendor to the security interest and/or liens in and to the property and/or
assets of the Borrowers,

         NOW, THEREFORE, in order to induce the Senior Agent and the Senior
Lenders to make and renew loans and extend credit to the Borrowers from time to
time and in consideration thereof, the parties hereto mutually intending to be
bound hereby agree to as follows:

         1.       All of the understandings, agreements, representations and
                  warranties contained herein are solely for the benefit of the
                  Senior Agent and the Senior Lenders and the Vendor and there
                  are no other parties (including the Borrowers) who are
                  intended to be benefited in any way by this Agreement.

         2.       Nothing contained herein is intended to affect or limit, in
                  any way, the assignments of and the security interests that
                  each of the parties hereto has in any and all of the assets of
                  the Borrowers, whether tangible or intangible, insofar as the
                  rights of the Borrower and third parties are involved. Except
                  as
<PAGE>   200
                  provided in paragraph 4 below, the parties hereto specifically
                  reserve all respective rights, security interests and rights
                  to assert security interests against the Borrowers.

         3.       The Vendor hereby agrees that all security interest in and
                  liens on all inventory, accounts receivable, proceeds and any
                  other property of the Borrowers, which the Vendor now has or
                  hereafter acquires, including without limitation any purchase
                  money security interests, shall be and hereby are subordinated
                  and junior to the security interests and liens in the
                  Borrowers' assets which the Senior Agent or Senior Lenders now
                  have or may hereafter acquire at any time.

         4.       The Vendor hereby agrees that so long as the Borrowers own any
                  amounts or have any outstanding obligations to the Senior
                  Agent or the Senior Lenders, the Vender will not assert or
                  exercise any rights or remedies as a secured party with
                  respect to the Borrowers' assets.

         5.       Nothing herein shall impair, as between Borrowers and the
                  Vendor, the obligation of Borrowers, which is unconditional
                  and absolute, to pay the Vendor the principal and premium, if
                  any, and interest on any debts or obligations as and when same
                  shall become due in accordance with their terms, nor shall
                  anything herein prevent the Vendor or its assignees from
                  exercising all remedies otherwise permitted by applicable law,
                  excluding its rights and remedies as a secured party, upon
                  default by Borrowers subject to the provisions of this
                  Agreement and the rights of the Senior Agent and the Senior
                  Lenders hereunder.

         6.       This agreement shall be binding upon the Senior Agent and the
                  Senior Lenders and the Vendor and inure to the benefit of each
                  and their respective successors and assigns.

         7.       All notices, demands and other communications hereunder shall
                  be in writing and shall be deemed to have been duly given if

                            SCHEDULE OF PENSION PLANS

New England Audio Company, Inc. 401(k) Retirement Plan, formerly New England
Audio Company Inc. Employee Savings Plan. The New England Audio Company Inc.
401(k) Retirement Plan, as approved by the Internal Revenue Service, has both
discretionary matching employer contributions and discretionary employer profit
sharing contributions, although a representative of the Internal Revenue Service
stated publicly both before and after the favorable determination letter was
issued that plans with such features might not qualify for tax purposes. Should
the Internal Revenue Service issue written guidance specifically stating that
such discretion can no longer appear in existing qualified retirement plans, the
Company will take the action required to keep its 401(k) plan in compliance with
the law.
