warranties and covenants of the Borrower herein, the Lender agrees to make

request given to the Lender pursuant to Section 2.3. Each request for a

limitations of this Agreement, the Borrower may convert all or a part of any
outstanding Loan into a Loan of another Type on any Business Day (which, in the

Interest Period applicable to such LIBOR Loan). The Borrower shall give the
Lender prior notice of each such conversion (which notice shall be effective
upon receipt) in accordance with Section 2.3.

            (ii) Subject to the provisions of Section 2.6 regarding mandatory
      payments, the Borrower shall have the right at any time and from time to
      time upon five (5) Business Days' prior written notice to the Lender to
      reduce by $1,000,000, and in integral multiples of $500,000 if in excess
      thereof, the Revolving Credit Commitment or to terminate entirely the
      Revolving Credit Commitment, whereupon the Revolving Credit Commitment
      shall be reduced by the amount specified in such notice or shall, as the
      case may be, be terminated entirely.

            (iii) If, as a result of any reduction of the Revolving Credit
      Commitment, the Maximum Drawing Amount at the time would exceed the
      Revolving Credit Commitment or the amount of Letters of Credit permitted
      to be outstanding under Sections 2.1(a) and 2A.1(a) hereof, the Borrower
      shall, as a condition precedent to any such reduction, deposit with and
      pledge to the Lender for the benefit of the Lender and the Issuing Bank
      cash in an amount equal to 110% of such excess. If any Letters of Credit
      would remain outstanding after the effective date of termination of the
      Revolving Credit Commitment, in addition to satisfaction of all other
      applicable terms and conditions of this Agreement, the Borrower shall
      deposit with and pledge to the Lender cash in an amount equal to 110% of
      the Maximum Drawing Amount at the effective date of such termination.

            (iv) No reduction or termination of any Commitment may be
      reinstated.

      2.2.  The Note.

            (a) The Revolving Credit Loans shall be evidenced by a promissory
note in substantially the form of Exhibit A hereto, dated as of the Closing Date

to be made, at or about the time of the Drawdown Date of any Loan or at the time
of receipt of any payment of principal on any Note, an appropriate notation on
its Note Record reflecting (as the case may be) the making of such Loan or the
receipt of such payment. The outstanding amount of the Loans set forth on the
Note Record shall be prima facie evidence of the principal amount thereof owing
and unpaid to the Lender, but the failure to record, or any error in so
recording, any such amount on the Lender's Note Record shall not limit or
otherwise affect the obligations of the Borrower hereunder or under any Note to
make payments of principal of or interest on any Note when due.

      2.3.  Notice and Manner of Borrowing or Conversion of Loans.

            (a) Except as otherwise provided in this Agreement, whenever the
Borrower desires to obtain or continue a Loan hereunder or convert an
outstanding Loan into a Loan of another Type, the Borrower shall give the Lender
a telephonic notice promptly confirmed by a written Notice of Borrowing or
Conversion, which telephonic notice shall be irrevocable and which must be
received no later than 2:00 p.m. Boston time on the date (i) one Business Day
before the day on which the requested Loan is to be made as or converted to a
Prime Rate Loan, and (ii) three Business Days before the day on which the
requested Loan is to be made or

                                      -16-
<PAGE>

continued as or converted to a LIBOR Loan. Such Notice of Borrowing or
Conversion shall specify (i) the effective date and amount of each Loan or
portion thereof requested to be made, continued or converted, subject to the
limitations set forth in Section 2.1, (ii) the interest rate option requested to
be applicable thereto, and (iii) the duration of the applicable Interest Period,
if any (subject to the provisions of the definition of the term "Interest
Period"). If such Notice fails to specify the interest rate option to be
applicable to the requested Loan, then the Borrower shall be deemed to have
requested a Prime Rate Loan. If the written confirmation of any telephonic
notification differs in any material respect from the action taken by the
Lender, the records of the Lender shall control absent manifest error.

            (b) Subject to the provisions of the definition of the term
"Interest Period" herein, the duration of each Interest Period for a LIBOR Loan
shall be as specified in the applicable Notice of Borrowing or Conversion. If no
Interest Period is specified in a Notice of Borrowing or Conversion with respect
to a requested LIBOR Loan, then the Borrower shall be deemed to have selected an
Interest Period of one month's duration. If the Lender receives a Notice of
Borrowing or Conversion after the time specified in subsection (a) above, such
Notice shall not be effective. If the Lender does not receive an effective
Notice of Borrowing or Conversion with respect to an outstanding LIBOR Loan, or
if, when such Notice must be given prior to the end of the Interest Period
applicable to such outstanding Loan, the Borrower shall have failed to satisfy
any of the conditions hereof, the Borrower shall be deemed to have elected to
convert such outstanding Loan in whole into a Prime Rate Loan on the last day of
the then current Interest Period with respect thereto.

      2.4.  Interest Rates and Payments of Interest.

            (a) Each Loan which is a Prime Rate Loan shall bear interest on the
outstanding principal amount thereof at a rate per annum equal to the Alternate
Prime Rate plus the Applicable Margin, which rate shall change contemporaneously
with any change in the Alternate Prime Rate or the Applicable Margin, as
provided below. Such interest shall be payable quarterly in arrears on the first
Business Day of each quarter.

            (b) Each Loan which is a LIBOR Loan shall bear interest on the
outstanding principal amount thereof, for each Interest Period applicable
thereto, at a rate per annum equal to the LIBOR Rate plus the Applicable Margin,
which rate shall change with any change in the Applicable Margin, as provided
below. Such interest shall be payable for such Interest Period on the last day
thereof and, if such Interest Period is longer than three months, at intervals
of three months after the first day thereof.

            (c) The Applicable Margin and the Leverage Ratio shall be determined
as of the end of each fiscal quarter based upon the quarterly financial
statements to be delivered pursuant to Section 5.1(b), and any change in the
Applicable Margin shall be effective upon the delivery of such financial
statements, provided, however that during any period when the Borrower has
failed to deliver such quarterly financial statements as required by Section
5.1(b), the Leverage Ratio shall be deemed to be greater than 1.00 to 1.00 for
purposes of determining the Applicable Margin.

                                      -17-
<PAGE>

            (d) If an Event of Default shall occur, then at the option of the
Lender (i) Borrower's right to select pricing options shall cease and the unpaid
balance of Loans shall bear interest, to the extent permitted by law, compounded
daily at an interest rate equal to the Prime Rate plus 4% per annum, until such
Event of Default is cured or waived.

            (e) So long as the Lender shall be required under regulations of the
Board of Governors of the Federal Reserve System (or any other banking
authority, domestic or foreign, to which the Lender is subject) to maintain
reserves with respect to liabilities or assets consisting of or including
"Eurocurrency Liabilities" (as defined in regulations issued from time to time
by such Board of Governors), the Borrower shall pay to the Lender additional
interest on the unpaid principal amount of each LIBOR Loan made by the Lender
from the date of such Loan until such principal amount is paid in full, at an
interest rate per annum equal at all times to the remainder (rounded upwards, if
necessary, to the next higher 1/100 of 1%) obtained by subtracting (i) the LIBOR
Rate for the Interest Period for such LIBOR Loan from (ii) the rate obtained by
dividing such LIBOR Rate by a percentage equal to 100% minus the Reserve
Percentage of the Lender for such Interest Period. Such additional interest
shall be determined by the Lender and notified to the Borrower, and shall be
payable on each date on which interest is payable on such LIBOR Loan.

            (f) All agreements between the Borrower and Guarantors and the
Lender are hereby expressly limited so that in no contingency or event
whatsoever, whether by reason of acceleration of maturity of the Loans or
otherwise, shall the amount paid or agreed to be paid to the Lender for the use
or the forbearance of the Loans exceed the maximum permissible under applicable
law. As used in this Section 2.4(f), the term "applicable law" shall mean the
law in effect as of the date hereof; provided, however, that in the event there
is a change in the law which results in a higher permissible rate of interest,
then this Agreement shall be governed by such new law as of its effective date.
In this regard, it is expressly agreed that it is the intent of the Borrower and
the Lender in the execution, delivery and acceptance of this Agreement to
contract in strict compliance with the laws of the Commonwealth of Massachusetts
from time to time in effect. If, under or from any circumstances whatsoever,
fulfillment of any provision hereof or of any of the Loan Documents at the time
of performance of such provision shall be due, shall involve transcending the
limit of such validity prescribed by applicable law, then the obligation to be
fulfilled shall automatically be reduced to the limits of such validity, and if
under or from any circumstances whatsoever the Lender should ever receive as
interest an amount which would exceed the highest lawful rate, such amount which
would be excessive interest shall be applied to the reduction of the principal
balance of the Loans and not to the payment of interest. This provision shall
control every other provision of all agreements between the Borrower, the
Guarantors and the Lender.

      2.5.  Fees.

            (a) The Borrower shall pay to the Lender a commitment fee (the
"Commitment Fee"), computed on a daily basis and payable quarterly in arrears on
the first Business Day of each quarter, equal to (i) the excess of (x) the
Revolving Credit Commitment at the time over (y) the Total Revolving
Outstandings at that time, multiplied by (ii) the Applicable Margin (as
determined in accordance with Section 2.4(c)).

                                      -18-
<PAGE>

            (b) The Borrower shall pay to the Lender for the benefit of the
Issuing Bank and the Lender a fee (the "Letter of Credit Fee") at a rate per
annum equal to (i) the Maximum Drawing Amount of each Letter of Credit
multiplied by (ii) the Applicable Margin (as determined in accordance with
Section 2.4(c)). The Letter of Credit Fee shall be paid quarterly in arrears on
the first Business Day of each quarter. In addition, the Borrower shall pay to
the Lender its standard service and setup fees in respect of Letters of Credit.

            (c) Without limiting any of the Lender's other rights hereunder or
by law, if any Loan or any portion thereof or any interest thereon or any other
amount payable hereunder or under any other Loan Document is not paid within ten
days after its due date, the Borrower shall pay to the Lender on demand a late
payment charge equal to 5% of the amount of the payment due.

            (d) The Borrower shall pay to the Lender, solely for the account of
the Lender, such other fees as the Borrower and the Lender shall agree,
including, without limitation, pursuant to the letter agreement dated September
15, 2000, between the Borrower and the Lender with respect to fees payable to
the Lender.

            (e) The Borrower authorizes the Issuing Bank and the Lender to
charge to its Note Record or to any deposit account which the Borrower may
maintain with any of them the interest, fees, charges, taxes and expenses
provided for in this Agreement, the other Loan Documents or any other document
executed or delivered in connection herewith or therewith.

      2.6.  Payments and Prepayments of the Loans.

            (a) On the Revolving Credit Maturity Date, the Borrower shall pay in
full the unpaid principal balance of all outstanding Revolving Credit Loans,
together with all unpaid interest thereon and all fees and other amounts due
with respect thereto.

            (b) If at any time the Total Revolving Credit Outstandings exceed
the lesser of (i) the Borrowing Base and (ii) the Revolving Credit Commitment,
the Borrower shall, within 24 hours of the occurrence of such excess, pay the
amount of any such excess to the Lender for application to the Revolving Credit
Loans.

            (c) The LIBOR Loans may be prepaid at any time, subject to the
provisions of Section 2.8, upon three (3) Business Days' notice. Prime Rate
Loans may be prepaid at any time, without premium or penalty, upon one (1)
Business Day's notice. Any such notice of prepayment shall be irrevocable.
Prepayments of Revolving Credit Loans may be reborrowed to the extent provided
in Section 2.1(a).

            (d) The Borrower shall pay to the Lender for application to the
Revolving Credit Loans, as provided in Section 2.7(b) below, an amount equal to
100% of the net cash proceeds of (i) sales of assets of the Borrower or any
Subsidiary of the Borrower (including sales of any securities owned by the
Borrower or any Subsidiary of the Borrower but excluding sales of inventory and
obsolete or worn-out equipment in the ordinary course of business, Qualified
Investments, shares in Switchboard and shares in Software.com) between the
Closing Date and the Revolver Maturity Date, (ii) sales of capital stock of the
Borrower or any Subsidiary of the Borrower if an Event of Default has occurred
and is continuing at the time such capital stock is sold, and (iii) insurance
proceeds, damage awards, condemnation awards and eminent domain awards received
by the Borrower or any Subsidiary of the

                                      -19-
<PAGE>

Borrower, to the extent such proceeds or awards are not applied to repair or
replace the damaged or taken property to which such proceeds or awards relate
within one year after the receipt thereof.

      2.7.  Method of Payments.

            (a) All payments by the Borrower hereunder and under any of the
other Loan Documents shall be made at the Lender's head office or at such other
location that the Lender may from time to time designate, in each case in lawful
currency of the United States of America in immediately available funds. All
such payments shall be made without set-off or counterclaim and free and clear
of and without deduction for any taxes, levies, imposts, duties, charges, fees,
deductions, withholdings, compulsory loans, restrictions or conditions of any
nature now or hereafter imposed or levied by any jurisdiction or any political
subdivision thereof or taxing or other authority therein unless the Borrower is
compelled by law to make such deduction or withholding. If any such obligation
is imposed upon the Borrower with respect to any amount payable by it hereunder
or under any of the other Loan Documents, the Borrower will pay to the Lender
such additional amount in U.S. Dollars as shall be necessary to enable the
Lender to receive the same net amount which the Lender would have received on
such due date had no such obligation been imposed upon the Borrower. The
Borrower will deliver promptly to the Lender certificates or other valid
vouchers or other evidence of payment reasonably satisfactory to the Lender for
all taxes or other charges deducted from or paid with respect to payments made
by the Borrower hereunder or under such other Loan Document. The Lender may, and
the Borrower hereby authorizes the Lender to, debit the amount of any payment
not made by such time to the demand deposit accounts of the Borrower with the
Lender or to its Note Record.

            (b) All funds received from or on behalf of the Borrower (including
as proceeds of Collateral) by the Lender or the Issuing Bank in respect of
Obligations, shall be applied by the Lender in the following manner and order:
(i) first, to reimburse the Lender and the Issuing Bank for any amounts payable
pursuant to Sections 10.2 and 10.3 hereof; (ii) second, to the payment of
Commitment Fees, Letter of Credit Fees and any other fees payable hereunder;
(iii) third, to the payment of interest due on the Loans and the Reimbursement
Obligations; (iv) fourth, to the payment of the outstanding principal balance of
the Loans and the Reimbursement Obligations, pro rata to the outstanding
principal balance of each; (v) fifth, to the payment of any other Obligations
payable by the Borrower, pro rata to the outstanding principal balance of each;
and (vi) any remaining funds shall be paid to whoever shall be entitled thereto
or as a court of competent jurisdiction shall direct, provided, however, if the
Commitments shall have been terminated or the Obligations shall have been
declared immediately due and payable pursuant to Section 8.2, payments will be
applied to the Obligations as the Lender determines in its sole discretion..

      2.8. Indemnity. If the Borrower for any reason (including, without
limitation, pursuant to Sections 2.6(b), 2.10, 2.11 and 8.2 hereof) makes any
payment of principal with respect to any LIBOR Loan on any day other than the
last day of an Interest Period applicable to

                                      -20-
<PAGE>

such LIBOR Loan, or fails to borrow or continue or convert to a LIBOR Loan after
giving a Notice of Borrowing or Conversion thereof pursuant to Section 2.3, or
fails to prepay a LIBOR Loan after having given notice thereof, the Borrower
shall pay to the Lender any amount required to compensate the Lender for any
additional losses, costs or expenses which it may reasonably incur as a result
of such payment or failure, including, without limitation, any loss (including
loss of anticipated profits), costs or expense incurred by reason of the
liquidation or re-employment of deposits or other funds required by the Lender
to fund or maintain such Loan. The Borrower shall pay such amount upon
presentation by the Lender of a statement setting forth the amount and the
Lender's calculation thereof pursuant hereto, which statement shall be deemed
true and correct absent manifest error. Without limiting the foregoing, the
Borrower shall pay to the Lender a "yield maintenance fee" in an amount computed
as follows: The current rate for United States Treasury securities (bills on a
discounted basis shall be converted to a bond equivalent) with a maturity date
closest to the term of the then applicable Interest Period as to which the
prepayment is made, shall be subtracted from the LIBOR Rate in effect at the
time of prepayment. If the result is zero or a negative number, there shall be
no yield maintenance fee. If the result is a positive number, then the resulting
percentage shall be multiplied by the amount of the principal balance being
prepaid. The resulting amount shall be divided by 360 and multiplied by the
number of days remaining in the term of the then applicable Interest Period as
to which the prepayment is made. Said amount shall be reduced to present value
calculated by using the above referenced United States Treasury securities rate
and the number of days remaining in the term of the then applicable Interest
Period as to which prepayment is made. The resulting amount shall be the yield
maintenance fee due to the Lender upon payment of a LIBOR Loan. If by reason of
an Event of Default, the Lender elects to declare the Notes to be immediately
due and payable, then any yield maintenance fee with respect to a LIBOR Loan
shall become due and payable in the same manner as though the Borrower had
exercised such right of prepayment.

      2.9. Computation of Interest and Fees. Interest and all fees payable
hereunder shall be computed daily on the basis of a year of 360 days and paid
for the actual number of days for which due. If the due date for any payment of
principal is extended by operation of law, interest and fees shall be payable
for such extended time. If any payment required by this Agreement becomes due on
a day that is not a Business Day such payment may be made on the next succeeding
Business Day (subject to the definition of the term "Interest Period"), and such
extension shall be included in computing interest and fees in connection with
such payment.

      2.10. Changed Circumstances; Illegality.

            (a) Notwithstanding any other provision of this Agreement, in the
      event that:

            (i) on any date on which the LIBOR Rate would otherwise be set the
      Lender shall have determined in good faith (which determination shall be
      final and conclusive) that adequate and fair means do not exist for
      ascertaining the LIBOR Rate, or

            (ii) at any time the Lender shall have determined in its reasonable
      good faith judgment (which determination shall be final and conclusive)
      that:

                                      -21-
<PAGE>

            (A) the making or continuation of or conversion of any Loan to a
      LIBOR Loan has been made impracticable or unlawful by (1) the occurrence
      of a contingency that materially and adversely affects the interbank LIBOR
      market or (2) compliance by the 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

            (B) the LIBOR Rate shall no longer represent the effective cost to
      the Lender for U.S. dollar deposits in the interbank market for deposits
      in which it regularly participates;

then, and in any such event, the Lender shall forthwith so notify the Borrower
thereof. Until the Lender notifies the Borrower that the circumstances giving
rise to such notice no longer apply, the obligation of the Lender to allow
selection by the Borrower of the Type of Loan affected by the contingencies
described in this Section (herein called "Affected Loans") shall be suspended.
If, at the time the Lender so notifies the Borrower, the Borrower has previously
given the Lender a Notice of Borrowing or Conversion with respect to one or more
Affected Loans but such Loans have not yet gone into effect, such notification
shall be deemed to be a request for Prime Rate Loans.

            (b) In the event of a determination of illegality pursuant to
subsection (a)(ii)(A) above, the Borrower shall, with respect to the outstanding
Affected Loans, prepay the same, together with interest thereon and any amounts
required to be paid pursuant to Section 2.9, on such date as shall be specified
in such notice (which shall not be earlier than the date such notice is given)
and may, subject to the conditions of this Agreement, borrow a Loan of another
Type in accordance with Section 2.1 hereof by giving a Notice of Borrowing or
Conversion pursuant to Section 2.3 hereof.

      2.11. Increased Costs. In case any change made after the Closing Date in
any law, regulation, treaty or official directive or the interpretation or
application thereof by any court or by any governmental authority charged with
the administration thereof or the compliance with any guideline or request of
any central bank or other governmental authority (whether or not having the
force of law):

            (i) subjects the Lender to any tax with respect to payments of
      principal or interest or any other amounts payable hereunder by the
      Borrower or otherwise with respect to the transactions contemplated hereby
      (except for taxes on the overall net income of the Lender imposed by the
      United States of America or any political subdivision thereof), or

            (ii) imposes, modifies or deems applicable any deposit insurance,
      reserve, special deposit or similar requirement against assets held by, or
      deposits in or for the account of, or loans by, the Lender (other than
      such requirements as are already included in the determination of the
      LIBOR Rate), or

                                      -22-
<PAGE>

            (iii) imposes upon the Lender any other condition with respect to
      its obligations or performance under this Agreement or in respect of any
      Letter of Credit,

and the result of any of the foregoing is to increase the cost to the Lender,
reduce the income receivable by the Lender or impose any expense upon the Lender
with respect to any Loans or its obligations under this Agreement or in respect
of any Letter of Credit, the Lender shall notify the Borrower thereof. The
Borrower agrees to pay to the Lender the amount of such increase in cost,
reduction in income or additional expense as and when such cost, reduction or
expense is incurred or determined, upon presentation by the Lender of a
statement in the amount and setting forth in reasonable detail the Lender's
calculation thereof and the assumptions upon which such calculation was based,
which statement shall be deemed true and correct absent manifest error, provided
however, if the Lender fails to give to notify the Borrower within 90 days
following the date such increase in cost, reduction in income or additional
expense is incurred or determined by the Lender, the Borrower shall not be
liable for any such increase in cost, reduction in income or additional expense
arising before the date of the Lender's notification thereof.

      2.12. Capital Requirements. If after the date hereof the Lender determines
that (i) the adoption of or change in any law, rule, regulation or guideline
regarding capital requirements for banks or bank holding companies, or any
change in the interpretation or application thereof by any governmental
authority charged with the administration thereof, or (ii) compliance by the
Lender or its parent bank holding company with any guideline, request or
directive of any such entity regarding capital adequacy (whether or not having
the force of law), has the effect of reducing the return on the Lender's or such
holding company's capital as a consequence of the Lender's Commitment to make
Loans hereunder or its obligations in respect of any Letter of Credit to a level
below that which the Lender or such holding company could have achieved but for
such adoption, change or compliance (taking into consideration the Lender's or
such holding company's then existing policies with respect to capital adequacy
and assuming the full utilization of such entity's capital) by any amount deemed
by the Lender to be material, then the Lender shall notify the Borrower thereof.
The Borrower agrees to pay to the Lender the amount of such reduction of return
on capital as and when such reduction is determined, payable within 90 days
after presentation by the Lender of a statement in the amount and setting forth
in reasonable detail the Lender's calculation thereof and the assumptions upon
which such calculation was based (which statement shall be deemed true and
correct absent manifest error) unless within such 90 day period the Borrower
shall have prepaid in full all Obligations to the Lender, in which event no
amount shall be payable to the Lender under this Section. In determining such
amount, the Lender may use any reasonable averaging and attribution methods.

                                  SECTION IIA

                                LETTERS OF CREDIT

      2A.1 Issuance. Upon the terms and subject to the conditions hereof, the
Issuing Bank, in reliance upon the representations and warranties of the
Borrower contained herein, agrees to issue letters of credit (the "Letters of
Credit") for the account of the Borrower in such form as may be requested from
time to time by the Borrower and agreed to by the Issuing Bank, provided

                                      -23-
<PAGE>

that the Maximum Drawing Amount (after giving effect to all requested Letters of
Credit) shall not at any time exceed the Letter of Credit Sublimit, provided,
further that the Total Revolving Credit Outstandings (after giving effect to all
requested Revolving Credit Loans and Letters of Credit) shall not at any time
exceed the lesser of (x) the Borrowing Base and (y) the Revolving Credit
Commitment, and provided further that no Letter of Credit shall have an
expiration date later than the Revolving Credit Maturity Date. At least three
(3) Business Days prior to the proposed issuance date of any Letter of Credit,
the Borrower shall deliver to the Issuing Bank a Letter of Credit Application
setting forth the Maximum Drawing Amount of all Letters of Credit (including the
requested Letter of Credit), the requested language of the requested Letter of
Credit and such other information as the Issuing Bank shall require. Each
request for the issuance of a Letter of Credit hereunder shall constitute a
representation and warranty by the Borrower that the conditions set forth in
Sections 3.1 and 3.2 have been satisfied as of the date of such request. The
letters of credit listed on Schedule 2 shall be deemed for all purposes to be
Letters of Credit issued for the account of the Borrower by the Issuing Bank
pursuant to this Section 2A.1.

      2A.2 Reimbursement Obligation of the Borrower. In order to induce the
Issuing Bank to issue, extend and renew each Letter of Credit, the Borrower
hereby agrees to reimburse or pay to the Lender, for the account of the Issuing
Bank or, as the case may be, the Lender, with respect to each Letter of Credit
issued, extended or renewed by the Issuing Bank hereunder as follows:

            (a) on each date that any draft presented under any Letter of Credit
is honored by the Issuing Bank or the Issuing Bank otherwise makes payment with
respect thereto, (i) the amount paid by the Issuing Bank under or with respect
to such Letter of Credit, and (ii) the amount of any taxes, fees, charges or
other costs and expenses whatsoever incurred by the Issuing Bank or the Lender
in connection with any payment made by the Issuing Bank under, or with respect
to, such Letter of Credit; and

            (b) upon the Revolving Credit Maturity Date or the acceleration of
the Reimbursement Obligations pursuant to Section 8, an amount equal to 110% of
the then Maximum Drawing Amount of all Letters of Credit, which amount shall be
held by the Issuing Bank as cash collateral for all Reimbursement Obligations.

Each such payment shall be made to the Lender at its head office in immediately
available funds. Interest on any and all amounts remaining unpaid by the
Borrower under this Section 2A.2 at any time from the date such amounts become
due and payable (whether as stated in this Section 2A.2, by acceleration or
otherwise) until payment in full (whether before or after judgment) shall be
payable to the Lender, for the account of Issuing Bank or (as the case may be)
the Lender, on demand at a rate per annum equal to 4% above the interest rate
applicable to Prime Rate Loans at the time in the absence of an Event of
Default.

      2A.3 Letter of Credit Payments. If any draft shall be presented or other
demand for payment shall be made under any Letter of Credit, the Issuing Bank
shall notify the Borrower 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. The responsibility of the Issuing

                                      -24-
<PAGE>

Bank to the Borrower shall be only to determine that the documents (including
each draft) delivered under each Letter of Credit in connection with such
presentment shall be in conformity with such Letter of Credit in accordance with
the standards set forth in the Issuing Bank's Letter of Credit Application. On
the date that such draft is paid or other payment is made by the Issuing Bank,
the Issuing Bank shall promptly notify the Lender of the amount of any unpaid
Reimbursement Obligation. All such unpaid Reimbursement Obligations with respect
to Letters of Credit shall be deemed to be Revolving Credit Loans.

      2A.4  Obligations Absolute.

            (a) The Borrower's Reimbursement Obligations shall be absolute and
unconditional under any and all circumstances and irrespective of the occurrence
of any Default or Event of Default or any condition precedent whatsoever or any
set off, counterclaim or defense to payment which the Borrower may have or have
had against the Issuing Bank, the Lender or any beneficiary of a Letter of
Credit. The Borrower further agrees that the Issuing Bank and the Lender shall
not be responsible for, and the Borrower's Reimbursement Obligations shall not
be affected by, among other things, the validity or genuineness of documents or
of any endorsements thereon, even if such documents should in fact prove to be
in any or all respects invalid, fraudulent or forged, or any dispute between or
among the Borrower, the beneficiary of any Letter of Credit or any financing
institution or other party to which any Letter of Credit may be transferred or
any claims or defenses whatsoever of the Borrower, against the beneficiary of
any Letter of Credit or any such transferee.

            (b) The Issuing Bank and the Lender shall not be liable for any
error, omission, interruption or delay in transmission, dispatch or delivery of
any message or advice, however transmitted, in connection with any Letter of
Credit. The Borrower agrees that any action taken or omitted by the Issuing Bank
or the Lender under or in connection with each Letter of Credit and the related
drafts and documents, if done in good faith, shall be binding upon the Borrower
and shall not result in any liability on the part of the Issuing Bank or the
Lender to the Borrower.

            (b) Nothing contained in Sections 2A.4(a) or (b) shall constitute a
forfeiture of any cause of action the Borrower may have against the Lender or
the Issuing Bank.

      2A.5 Reliance by the Issuing Bank and the Lender. To the extent not
inconsistent with Section 2A.4, the Issuing Bank and the Lender shall be

letter, cablegram, telegram, telecopy, telex or teletype message, statement,
order or other document believed by it to be genuine and correct and to have
been signed, sent or made by the proper Person or Persons and upon advice and
statements of legal counsel, independent accountants and other experts selected
by the Issuing Bank or the Lender.

                                  SECTION IV.

                         REPRESENTATIONS AND WARRANTIES

      In order to induce the Lender and the Issuing Bank to enter into this
Agreement and to make Loans and to issue Letters of Credit hereunder, the
Borrower represents and warrants to the Lender and the Issuing Bank that except
as set forth on Exhibit C attached hereto:

      4.1. Organization; Qualification; Business.

            (a) Each of the Borrower and its Subsidiaries (all of which are
listed in Exhibit C attached hereto), except for the Inactive Subsidiaries, (i)
is a corporation duly organized, validly existing and in good standing under the
laws of its jurisdiction of formation, (ii) has all requisite power to own its
property and conduct its business as now conducted and as presently contemplated
and (iii) is duly qualified and in good standing as a foreign corporation and is
duly authorized to do business in each jurisdiction (all of which are listed on
Exhibit C attached hereto) where the nature of its properties or business
requires such qualification, except where the failure to be so qualified would
not have a material adverse effect on the business, financial condition, assets
or properties of the Borrower or of the Borrower and its Subsidiaries taken as a
whole.

            (b) Since the date of the Initial Financial Statement, the Borrower
has continued to engage in substantially the same business as that in which it
was then engaged and is engaged in no unrelated business except as otherwise
expressly permitted by this Agreement.

      4.2. Corporate Authority. The execution, delivery and performance of the
Loan Documents and the transactions contemplated thereby are within the power
and authority of the Borrower and have been authorized by all necessary
corporate proceedings, and do not and will not (a) contravene any provision of
the Certificate of Incorporation or By-laws of the Borrower or any law, rule or
regulation applicable to the Borrower, (b) contravene any provision of, or
constitute an event of default or event that, but for the requirement that time
elapse or notice be given, or both, would constitute an event of default under,
any other material agreement, instrument, order or undertaking binding on the
Borrower, or (c) result in or require the imposition of any Encumbrance on any
of the properties, assets or rights of the Borrower, except in favor of the
Lender and the Issuing Bank.

      4.3. Valid Obligations. The Loan Documents and all of their respective
terms and provisions are the legal, valid and binding obligations of the
Borrower, enforceable in accordance with their respective 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 of injunctive relief is subject to the
discretion of the court before which any proceeding therefor may be brought. The
Security Documents have effectively created in favor of the Lender legal, valid
and enforceable security interests in the Collateral and such security interests
are fully perfected first priority security interests junior only to Permitted
Encumbrances.

                                      -29-
<PAGE>

      4.4. Consents or Approvals. The execution, delivery and performance of the
Loan Documents and the transactions contemplated herein do not require any
approval or consent of, or filing or registration with, any governmental or
other agency or authority, or any other Person (including without limitation any
lessor or lessee of Borrower's properties), except under or as contemplated by
the Security Documents.

      4.5. Title to Properties; Absence of Encumbrances. Each of the Borrower
and the Guarantors has good and marketable title to all of the properties,
assets and rights of every name and nature now purported to be owned by it, and
good and valid leasehold title to all of the properties, assets and rights of
every name and nature now purported to be leased by it, including, without
limitation, such properties, assets and rights as are reflected in the Initial
Financial Statement (except such properties, assets or rights as have been
disposed of in the ordinary course of business since the date thereof or as
otherwise expressly permitted by this Agreement), free from all Encumbrances
except Permitted Encumbrances, and, except as so disclosed, free from all
defects of title that might materially adversely affect such properties, assets
or rights, or Borrower's or the Guarantors' operations conducted with respect
thereto, taken as a whole, provided, however, the foregoing representation shall
not apply to the Banyan Intellectual Property. All material leases under which
Borrower or the Guarantors is the lessor or lessee are in full force and effect
and there are no existing defaults or events that with the giving of notice or
passage of time or both could ripen into defaults by either party thereunder
which defaults, individually or in the aggregate, might have a material adverse
effect on the Borrower. No third parties possess any rights with respect to any
of Borrower's or the Guarantors owned or leased properties, the exercise of
which would have a material adverse effect on the Borrower or the Guarantors or
their respective operations, taken as a whole. All real property, if any, owned
or leased by the Borrower is described in Exhibit C hereto.

      4.6. Financial Statements. The Borrower has furnished to the Lender (x)
its consolidated balance sheet as of December 31, 1999 and its consolidated
statement of income, changes in stockholders' equity and cash flow for the
fiscal year then ended, and related footnotes, audited and certified by the
Borrower's Accountants and (y) its consolidating balance sheet as of December
31, 1999 and its consolidating statement of income, changes in stockholders'
equity and cash flow for the fiscal year then ended certified by its chief
financial officer. The Borrower has also furnished to the Lender its unaudited
consolidated and consolidating balance sheet as of June 30, 2000 and its
unaudited consolidated and consolidating statements of income, changes in
stockholders' equity and cash flow for the 6 months then ended (the "Initial
Financial Statement"), certified by the principal financial officer of the
Borrower, subject to normal, recurring year-end adjustments that shall not in
the aggregate be material in amount. All such financial statements were prepared
in accordance with GAAP applied on a consistent basis throughout the periods
specified and present fairly the financial position of the Borrower and its
Subsidiaries as of such dates and the results of the operations of the Borrower
and its Subsidiaries for such periods. At the date hereof, the Borrower has no
Indebtedness or other material liabilities, debts or obligations, whether
accrued, absolute, contingent or otherwise, and whether due or to become due,
including, but not limited to, liabilities or obligations on account of taxes or
other governmental charges, that are not set forth on the Initial Financial
Statement or on Exhibit C hereto.

                                      -30-
<PAGE>

      4.7. Changes. Since the date of the Initial Financial Statement, there
have been no material changes in the assets, liabilities, financial condition,
business or prospects of the Borrower or any of its Subsidiaries other than
changes in the ordinary course of business or as expressly permitted by this
Agreement, the effect of which has not, in the aggregate, been materially
adverse to the Borrower and its Subsidiaries taken as a whole.

      4.8. Solvency. The Borrower has and, after giving effect to the Loans,
will have, assets (both tangible and intangible) having a fair saleable value in
excess of the amount required to pay the probable liability on its then-existing
debts (whether matured or unmatured, liquidated or unliquidated, fixed or
contingent); the Borrower has and will have access to adequate capital for the
conduct of its business and the discharge of its debts incurred in connection
therewith as such debts mature; the Borrower was not insolvent immediately prior
to the making of the Loans and immediately after giving effect thereto, the
Borrower will not be insolvent.

      4.9. Defaults. As of the date of this Agreement, no Default exists.

      4.10. Taxes. The Borrower and its Subsidiaries have filed all (i) federal
and state and, (ii) except where the failure to file any such return would not
have a material adverse effect on the business of the Borrower and its
Subsidiaries taken as a whole, all other tax returns required to be filed, and
all taxes, assessments and other governmental charges due from any of them have
been fully paid, except for such taxes, assessments or charges that are being
contested in good faith by appropriate proceedings and with respect to which (a)
adequate reserves have been established and are being maintained in accordance
with GAAP and (b) no lien has been filed to secure such taxes, assessments or
charges. All such contests at the date hereof are described on Exhibit C hereto.
The Borrower and its Subsidiaries have not executed any waiver that would have
the effect of extending the applicable statute of limitations in respect of tax
liabilities. Except as disclosed on Exhibit C, the foreign, federal and state
income tax returns of the Borrower and its domestic Subsidiaries, and to the
best of the Borrower's knowledge the foreign Subsidiaries, have not been audited
or otherwise examined by any foreign, federal or state taxing authority and
there are no outstanding deficiencies with respect to such audited returns which
have not been satisfied within 10 Business Days of the assessment of such
deficiency. The Borrower and its Subsidiaries have established on their books
reserves adequate for the payment of all federal, state and other tax
liabilities.

      4.11. Litigation. There is no litigation, arbitration, proceeding or
investigation pending, or, to the knowledge of the Borrower's or any
Subsidiary's officers, threatened, against the Borrower or any Subsidiary that,
if adversely determined, may reasonably be expected to result in a material
judgment not fully covered by insurance, may reasonably be expected to result in
a forfeiture of all or any substantial part of the property of the Borrower or
its Subsidiaries, or may reasonably be expected to have a material adverse
effect on the assets, business or prospects of the Borrower and its Subsidiaries
taken as a whole.

      4.12. Subsidiaries. All the Subsidiaries of the Borrower are listed on
Exhibit C hereto. The Borrower or a Subsidiary of the Borrower is the owner,
free and clear of all Encumbrances, of all of the issued and outstanding stock
or other equity interest of each Subsidiary. All shares of such stock or other
equity interest have been validly issued and are fully paid and

                                      -31-
<PAGE>

nonassessable, and no rights to subscribe to any additional shares have been
granted, and no options, warrants or similar rights are outstanding.

      4.13. Investment Company Act. Neither the Borrower nor any of its
Subsidiaries is subject to regulation under the Investment Company Act of 1940,
as amended.

      4.14. Compliance. The Borrower and each of the Guarantors have all
necessary permits, approvals, authorizations, consents, variances, licenses,
franchises, registrations and other rights and privileges (including patents,
trademarks, trade names and copyrights) to allow them to own and operate their
respective businesses and properties without any violation of laws, regulations,
authorizations and orders of public authorities (including without limitation
Environmental Laws) or the rights of others except to the extent that any such
violation would not have a material adverse effect on the business, financial
condition or operation of the Borrower and its Subsidiaries taken as a whole;
and the Borrower and each Subsidiary are duly authorized, qualified and licensed
under, and Borrower, its Subsidiaries and all real properties owned or leased by
them are in compliance with, all applicable laws, regulations, authorizations
and orders of public authorities, including, without limitation, Environmental
Laws, except to the extent that any such failure to be so authorized, qualified,
licensed or in compliance would not have a material adverse effect on the
business, financial condition or operation of the Borrower and its Subsidiaries
taken as a whole. The Borrower and each Subsidiary have performed all
obligations required to be performed by it under, and is not in default under or
in violation of, its Certificate of Incorporation or By-laws or any other
material agreement, lease, mortgage, note, bond, indenture, license or other
instrument or undertaking to which it is a party or by which any of it or any of
its properties are bound, except for violations none of which, either
individually or in the aggregate, would have any material adverse effect on the
business, condition (financial or otherwise) or assets of the Borrower and its
Subsidiaries taken as a whole.

      4.15. ERISA. The Borrower and its ERISA Affiliates are in compliance in
all material respects with ERISA and the provisions of the Code and the
regulations and published interpretations thereunder applicable to the Plans. No
ERISA Event has occurred or is reasonably expected to occur, including by reason
of the consummation of the transactions contemplated by this Agreement that,
when taken together with all other such ERISA Events, could reasonably be
expected to result in material liability to the Borrower or any of its ERISA
Affiliates. None of the Plans had any "unfunded benefit liabilities" (within the
meaning of Section 4001(a)(18) of ERISA) as of the last annual valuation dates
applicable thereto.

      4.16. Environmental Matters.

            (a) The Borrower and each of its Subsidiaries have obtained all
permits, licenses and other authorizations which are required under all
Environmental Laws, except to the extent failure to have any such permit,
license or authorization would not have a material adverse effect on the
business, financial condition or operations of the Borrower or any of its
Subsidiaries. The Borrower and each of its Subsidiaries are in compliance with
the terms and conditions of all such permits, licenses and authorizations, and
are also in compliance with all applicable orders, decrees, judgments and
injunctions, issued, entered, promulgated or approved under any Environmental
Law, except to the extent failure to comply would not have a material

                                      -32-
<PAGE>

adverse effect on the business, financial condition or operations of the
Borrower and its Subsidiaries taken as a whole.

            (b) No written notice, notification, demand, request for
information, citation, summons or order has been issued and is outstanding, no
complaint has been filed, no penalty has been assessed and no investigation or
review is pending or, to the best of the Borrower's knowledge, threatened by any
governmental or other entity (i) with respect to any alleged failure by the
Borrower or any of its Subsidiaries to have any permit, license or authorization
required under any Environmental Law in connection with the conduct of its
business or to comply with any Environmental Laws, or (ii) alleging any
liability on the part of the Borrower or any Subsidiary under any Environmental
Law regarding the presence of any Hazardous Material at, on or under any
property now or previously owned, leased or used by the Borrower or any of its
Subsidiaries or any other location to which Hazardous Materials from such
property had been transported or at which they have been disposed of, except to
the extent failure to comply would not have a material adverse effect on the
business, financial condition or operations of the Borrower and its Subsidiaries
taken as a whole.

            (c) No material oral or written notification of a release of a
Hazardous Material has been filed by or on behalf of the Borrower or any of its
Subsidiaries, and to the best of the Borrower's knowledge, no property now or
previously owned, leased or used by the Borrower or any of its Subsidiaries is
listed or, proposed for listing on the National Priorities List under the
Comprehensive Environmental Response, Compensation and Liability Act of 1980, as
amended, or on any similar state list of sites requiring investigation or
clean-up.

            (d) To the best of the Borrower's knowledge, there are no
Encumbrances arising under or pursuant to any Environmental Law on any of the
real property or properties owned, leased or used by the Borrower or any of its
Subsidiaries and no governmental actions have been taken or, to the best of the
Borrower's knowledge, are in process which could subject any of such properties
to such liens or Encumbrances or, as a result of which the Borrower or any of
its Subsidiaries would be required to place any notice or restriction relating
to the presence of Hazardous Materials at any property owned by it in any deed
to such property.

            (e) Neither the Borrower nor any of its Subsidiaries nor, to the
best knowledge of the Borrower without investigation, any previous owner,
tenant, occupant or user of any property owned, leased or used by the Borrower
or any of its Subsidiaries has (i) engaged in or permitted any operations or
activities upon or any use or occupancy of such property, or any portion
thereof, for the handling, manufacture, treatment, storage, use, generation,
release, discharge, refining, dumping or disposal of any Hazardous Materials on,
under, in or about such property, except to the extent commonly used in
day-to-day operations of such property and in such case only in compliance in
all material respects with all Environmental Laws, or (ii) transported any
Hazardous Materials to, from or across such property except to the extent
commonly used in day-to-day operations of such property and, in such case, in
compliance in all material respects with, all Environmental Laws; nor to the
best knowledge of the Borrower without investigation have any Hazardous
Materials migrated from other properties upon, about or beneath such property,
nor, to the best knowledge of the Borrower, are any Hazardous Materials
presently deposited, stored or otherwise located on, under, in or about such
property

                                      -33-
<PAGE>

except to the extent commonly used in day-to-day operations of such property
and, in such case, in compliance in all material respects with all Environmental
Laws.

      4.17. Restrictions on the Borrower. Neither the Borrower nor any of its
Subsidiaries is party to or bound by any contract, agreement or instrument, nor
subject to any charter or other corporate restriction which will, under current
or foreseeable conditions, materially and adversely affect the business,
property, assets, operations or conditions, financial or otherwise of the
Borrower and its Subsidiaries taken as a whole.

      4.18. Labor Relations. There is (i) no unfair labor practice complaint
pending against the Borrower or any of its Subsidiaries or, to the best
knowledge of the Borrower, threatened, before the National Labor Relations
Board, and no grievance or arbitration proceeding arising out of or under any
collective bargaining agreement is so pending against the Borrower or any of its
Subsidiaries or, to the best knowledge of the Borrower, threatened, except for
such complaints, grievances and arbitration proceedings which, if adversely
decided, would not have a material and adverse effect on the condition

Borrower or any of its Subsidiaries, (ii) no strike, labor dispute, slowdown or
stoppage pending against the Borrower or any of its Subsidiaries or, to the best

      4.19. Margin Rules. The Borrower does not own or have any present
intention of purchasing or carrying, and no portion of any Loan shall be used

terms are used in Regulations T, U or X of the Board of Governors of the Federal
Reserve System.

      4.20. Disclosure. No representation or warranty made by the Borrower in
any Loan Document and no document or information furnished to the Lender by or
on behalf of or at the request of the Borrower in connection with any of the
transactions contemplated by the Loan Documents contains any untrue statement of

Property under the agreements disclosed pursuant to paragraph (d) below and

and software that is generally commercially available, the Borrower is not
obligated to pay any royalties or other compensation to any third party in

<PAGE>

respect to all Collateral.

                                  SECTION IX.

                          ASSIGNMENT AND PARTICIPATION

      9.1.  Assignment.

            (a) Fleet shall have the right to assign at any time all or any
portion of its Commitment hereunder and its interests in the risk relating to
any Loans in an amount equal to or greater than $1,000,000 to other banks or
financial institutions (each an "Assignee") provided that if no Default or Event
of Default shall have occurred and be continuing, each Assignee which is not an
Affiliate of Fleet or a Federal Reserve Bank shall be subject to prior approval
by the Borrower (such approval not to be unreasonably withheld or delayed). Each
Assignee shall execute and deliver to Fleet and the Borrower a joinder
agreement. Upon the execution and delivery of such joinder agreement, (a) such
Assignee shall, on the date and to the extent provided in such joinder
agreement, become a "Lender" party to this Agreement and the other Loan
Documents for all purposes of this Agreement and the other Loan Documents and
shall have all rights and obligations of a "Lender" with a Commitment as set
forth in such joinder agreement, and Fleet shall, on the date and to the extent
provided in such joinder agreement, be released prospectively from its
obligations hereunder and under the other Loan Documents to a

                                      -49-
<PAGE>

corresponding extent (and, in the case of an assignment covering all of the
remaining portion of Fleet's rights and obligations under this Agreement, Fleet
shall cease to be a party hereto but shall continue to be entitled to the
benefits of Section 10.3 and to any fees accrued for its account hereunder and
not yet paid); (b) the assigning Lender, if it holds any Notes, shall promptly
surrender such Notes to the Borrower for cancellation, provided that if Fleet
has retained any Commitment, the Borrower shall execute and deliver to Fleet new
Notes in the amount of its retained Commitment; (c) the Borrower shall issue to
such Assignee Notes in the amount of such Assignee's Commitment, dated the
Closing Date or such other date as may be specified by such Assignee and
otherwise completed in substantially the form of Exhibit A; (d) this Agreement
shall be deemed appropriately amended to reflect (i) the status of such Assignee
as a party hereto and (ii) the status and rights of the Lenders hereunder; and
(e) the Borrower shall take such action as Fleet may reasonably request to
perfect any security interests or mortgages in favor of the Lenders.

            (b) If the Assignee, or any Participant pursuant to Section 9.2
hereof, is organized under the laws of a jurisdiction other than the United
States or any state thereof, such Assignee shall execute and deliver to the
Borrower, simultaneously with or prior to such Assignee's execution and delivery
of the counterpart joinder described above in Section 9.1(a), and such
Participant shall execute and deliver to the Lender, a United States Internal
Revenue Service Form W-8ECI or W-8BEN (or any successor form), appropriately
completed, wherein such Assignee or Participant claims entitlement to complete
exemption from United States Federal Withholding Tax on all interest payments
hereunder and all fees payable pursuant to any of the Loan Documents. The
Borrower shall not be required to pay any increased amount to any Assignee or
other Lender on account of taxes to the extent such taxes would not have been
payable if the Assignee or Participant had furnished one of the Forms referenced
in this Section 9.1(b) unless the failure to furnish such a Form results from
(i) a condition or event affecting the Borrower or an act or failure to act of
the Borrower or (ii) the adoption of or change in any law, rule, regulation or
guideline affecting such Assignee or Participant occurring (x) after the date on
which any such Assignee executes and delivers the counterpart joinder, or (y)
after the date such Assignee shall otherwise comply with the provisions of
Section 9.1(a), or (z) after the date a Participant is granted its
participation.

            (c) The Lender may at any time pledge all or any portion of its
rights under the Loan Documents including any portion of this Note to any of the
twelve (12) Federal Reserve Banks organized under Section 4 of the Federal
Reserve Act, 12 U.S.C. Section 341. No such pledge or assignment or enforcement
thereof shall release the Lender from its obligations under any of the Loan
Documents.

      9.2. Participations. The Lender shall have the unrestricted right to grant
participations to one or more banks or other financial institutions (each a
"Participant") in all or any part of any Loans owing to the Lender and the Note
held by the Lender. The Lender shall retain the sole right to approve, without
the consent of any Participant, any amendment, modification or waiver of any
provision of the Loan Documents, provided that the documents evidencing any such
participation may provide that, except with the consent of such Participant, the
Lender will not consent to (a) the reduction in or forgiveness of the stated
principal of or rate of interest on or commitment fee with respect to the
portion of any Loan subject to such participation, (b) the

                                      -50-
<PAGE>

extension or postponement of any stated date fixed for payment of principal or
interest or commitment fee with respect to the portion of any Loan subject to
such participation, (c) the waiver or reduction of any right to indemnification
of the Lender hereunder, or (d) except as otherwise permitted hereunder, the
release of any Collateral. Notwithstanding the foregoing, no participation shall
operate to increase the total Commitments hereunder or otherwise alter the
substantive terms of this Agreement. In the event of any such sale by the Lender
of participating interests to a Participant, the Lender's obligations under this
Agreement shall remain unchanged, the Lender shall remain solely responsible for
the performance thereof, the Lender shall remain the holder of such Note for all
purposes under this Agreement and the Borrower shall continue to deal solely and
directly with the Lender in connection with the Lender's rights and obligations
under this Agreement.

<PAGE>

transactions contemplated by, associated with or ancillary to this Agreement,
the other Loan Documents or any other documents executed or delivered in
connection herewith or therewith, all as the same may be amended from time to
time, or with respect to any Letters of Credit, whether or not all or part of

ultimately consummated. In any investigation, proceeding or litigation, or the

Obligation remains outstanding and unpaid or the Lender has any obligation to
make any Loans hereunder or the Issuing Bank has any obligation to issue any
Letter of Credit. All statements contained in any certificate or other writing
delivered by or on behalf of the Borrower pursuant hereto or in connection with
the transactions contemplated hereby shall constitute representations and
warranties by the Borrower hereunder.

      10.5. Set-Off. The Borrower hereby grants to the Lender, a lien, security
interest and right of setoff as security for all liabilities and obligations to
the Lender, whether now existing or hereafter arising, upon and against all
deposits, credits, collateral and property, now or hereafter in the possession,
custody, safekeeping or control of the Lender or any entity under the control of
FleetBoston Financial Corporation and its successors and assigns, or in transit
to any of them. At any time following the occurrence of an Event of Default,
without demand or notice (any such notice being expressly waived by the
Borrower), the Lender may set off the same or any part thereof and apply the
same to any liability or obligation of the undersigned even though unmatured and
regardless of the adequacy of any other collateral securing the Loan. ANY AND
ALL RIGHTS TO REQUIRE THE LENDER TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT
TO ANY OTHER COLLATERAL WHICH SECURES THE LOAN, PRIOR TO EXERCISING THE RIGHT OF
SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF THE BORROWER
ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED.

      10.6. No Waivers. No failure or delay by the Lender or the Issuing Bank in
exercising any right, power or privilege hereunder, under the Notes or under any
other Loan Document shall operate as a waiver thereof; nor shall any single or
partial exercise thereof preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. No waiver

                                      -53-
<PAGE>

shall extend to or affect any Obligation not expressly waived or impair any
right consequent thereon. No course of dealing or omission on the part of the
Lender or the Issuing Bank in exercising any right shall operate as a waiver
thereof or otherwise be prejudicial thereto. No notice to or demand upon the
Borrower shall entitle the Borrower to other or further notice or demand in
similar or other circumstances. The rights and remedies herein and in the Notes
and the other Loan Documents are cumulative and not exclusive of any rights or
remedies otherwise provided by agreement or law.

      10.7. Amendments, Waivers, etc. Neither this Agreement nor the Notes nor
any other Loan Document nor any provision hereof or thereof may be amended,
waived, discharged or terminated except by a written instrument signed by the
Lender and, with respect to Letters of Credit, the Issuing Bank, and also, in
the case of amendments, by the Borrower.

      10.8. Binding Effect of Agreement. This Agreement shall be binding upon
and inure to the benefit of the Borrower, the Lender, the Issuing Bank and their
respective successors and assigns; provided that the Borrower may not assign or
transfer its rights or obligations hereunder.

      10.9. Captions; Counterparts. The captions in this Agreement are for
convenience of reference only and shall not define or limit the provisions
hereof. This Agreement and any amendment hereof may be executed in several
counterparts and by each party on a separate counterpart, each of which when so
executed and delivered shall be an original, but all of which together shall
constitute one instrument. In proving this Agreement it shall not be necessary
to produce or account for more than one such counterpart signed by the party
against whom enforcement is sought.

      10.10. Entire Agreement, Etc. The Loan Documents and any other documents
executed in connection herewith or therewith express the entire understanding of
the parties with respect to the transactions contemplated hereby and supersede
all prior agreements (including the Commitment Letter dated September 15, 2000
between Lender and the Borrower) with respect to the subject matter hereof,
except for the letter agreement dated September 15, 2000, between the Borrower
and Lender with respect to fees payable to Lender, which letter agreement shall
continue in full force and effect and shall not be superseded by any of the Loan
Documents.

      10.11. Waiver of Jury Trial. THE BORROWER AND THE LENDER MUTUALLY HEREBY
KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE THE RIGHT TO TRIAL BY JURY IN
RESPECT OF ANY CLAIM BASED HEREON, ARISING OUT OF, UNDER OR IN CONNECTION WITH
THIS AGREEMENT OR ANY OTHER LOAN DOCUMENTS CONTEMPLATED TO BE EXECUTED IN
CONNECTION HEREWITH OR ANY COURSE OF CONDUCT, COURSE OF DEALINGS, STATEMENTS
(WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY PARTY, INCLUDING, WITHOUT
LIMITATION, ANY COURSE OF CONDUCT, COURSE OF DEALINGS, STATEMENTS OR ACTIONS OF
THE LENDER RELATING TO THE ADMINISTRATION OF THE LOAN OR THE ENFORCEMENT OF THE
LOAN DOCUMENTS, AND AGREE THAT NEITHER PARTY WILL SEEK TO CONSOLIDATE ANY SUCH
ACTION WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT BE OR HAS NOT BEEN
WAIVED. EXCEPT AS PROHIBITED BY LAW, EACH OF THE BORROWER AND THE LENDER

                                      -54-
<PAGE>

HEREBY WAIVES ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY LITIGATION ANY
SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES OTHER THAN,
OR IN ADDITION TO, ACTUAL DAMAGES. THE BORROWER CERTIFIES THAT NO
REPRESENTATIVE, AGENT OR ATTORNEY OF THE LENDER HAS REPRESENTED, EXPRESSLY OR
OTHERWISE, THAT THE LENDER WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO
ENFORCE THE FOREGOING WAIVERS. THE WAIVERS AND CERTIFICATIONS CONTAINED HEREIN
CONSTITUTE A MATERIAL INDUCEMENT FOR THE LENDER TO ENTER INTO THIS AGREEMENT AND
THE OTHER LOAN DOCUMENTS TO WHICH EACH IS A PARTY AND TO MAKE THE LOAN.

      10.12. Governing Law. THIS AGREEMENT AND EACH OF THE OTHER LOAN DOCUMENTS
ARE CONTRACTS UNDER THE LAWS OF THE COMMONWEALTH OF MASSACHUSETTS AND SHALL FOR
ALL PURPOSES BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF SAID
COMMONWEALTH (EXCLUDING THE LAWS APPLICABLE TO CONFLICTS OR CHOICE OF LAW). THE
BORROWER CONSENTS TO THE JURISDICTION OF ANY OF THE FEDERAL OR STATE COURTS
LOCATED IN SUFFOLK COUNTY IN THE COMMONWEALTH OF MASSACHUSETTS IN CONNECTION
WITH ANY SUIT TO ENFORCE THE RIGHTS OF THE LENDER UNDER THIS AGREEMENT OR ANY OF
THE OTHER LOAN DOCUMENTS. THE BORROWER IRREVOCABLY WAIVES ANY OBJECTION WHICH IT
MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUCH ACTION BROUGHT IN
THE COURTS REFERRED TO IN THE PRECEDING SENTENCE AND IRREVOCABLY WAIVES AND
AGREES NOT TO PLEAD OR CLAIM IN ANY SUCH ACTION THAT SUCH ACTION HAS BEEN
BROUGHT IN AN INCONVENIENT FORUM.

      10.13. Severability. The provisions of this Agreement are severable and if
any one clause or provision hereof shall be held invalid or unenforceable in
whole or in part in any jurisdiction, then such invalidity or unenforceability
shall affect only such clause or provision, or part thereof, in such
jurisdiction, and shall not in any manner affect such clause or provision in any
other jurisdiction, or any other clause or provision of this Agreement in any
jurisdiction.

      10.14. Replacement of Lost Notes. Upon receipt of an affidavit of an
officer of the Lender as to the loss, theft, destruction or mutilation of the
Notes or any other Security Document which is not of public record, and , in the
case of any such loss, theft, destruction or mutilation, upon cancellation of
such Notes or other Security Document and proper indemnification of the Borrower
by the Lender, the Borrower will issue, in lieu thereof, a replacement note or
other security document in the same principal amount thereof or otherwise of
like tenor.

      10.15. Confidentiality. The Lender will maintain the confidentiality of
any non-public information relating to the Borrower which has been identified in
writing as confidential on the information itself or otherwise, including
without limitation, any information obtained pursuant to Section 5.5, (the

prevent the unauthorized disclosure of the Confidential Information to third
parties. Confidential Information shall not include information that either: (a)
is in the public domain or in the knowledge or possession of the Lender when
disclosed to the Lender, or becomes part of the public domain after disclosure
to the Lender through no fault of the Lender; or (b) is disclosed to the Lender
by a third party, provided the Lender does not have actual knowledge that such
third party is prohibited from disclosing such information. The terms of this
Section shall not apply to disclosure of Confidential Information by the Lender

SECTION 3. The Security Interests

      (a) In order to secure the full and punctual payment of the Secured
Obligations in accordance with the terms thereof, the Borrower hereby, assigns,
pledges and grants to the Lender a continuing security interest and lien in and
to all right, title and interest of the Borrower in the following property,
other than Excluded Property, whether now owned or existing or hereafter
acquired or arising and regardless of where located (all being collectively
referred to as the "Collateral"):

            (i)   Accounts;

            (ii)  Inventory;

            (iii) General Intangibles;

            (iv)  Documents;

            (v)   Instruments;

            (vi)  Investment Property;

            (vii) Equipment;

            (viii) Fixtures;

            (ix) All books and records (including, without limitation, customer
      lists, marketing information, credit files, price lists, operating
      records, vendor and supplier price lists, sales literature, computer
      programs, printouts and other computer materials and records) of the
      Borrower pertaining to any of the Collateral;

            (x) All other property of the Borrower of every kind and
      description, tangible and intangible, and

            (xi) All Proceeds of, attachments or accessions to, or substitutions
      for all or any of the Collateral described in Clauses (i) through (x)
      hereof,

provided however, that the foregoing security interest shall not include a
security interest in any Collateral comprised of Intellectual Property of the
Borrower or any of its Subsidiaries (the "Intellectual Property Collateral") if
the granting of the security interest therein by the Borrower to the Lender is
prohibited by any requirement of law or by the terms and provisions of the
written agreement, document or instrument creating or evidencing such
Intellectual Property Collateral or rights related thereto and provided further,
that if and when the prohibition which prevents the granting by the Borrower to
the Lender of a security interest in such Intellectual

                                        5

<PAGE>

Property Collateral is removed or otherwise terminated, the Lender will be
deemed to have, and at all times from and after the date hereof to have had, a
security interest in such Intellectual Property Collateral, as the case may be,
and that, notwithstanding anything set forth herein to the contrary, the Lender
will be deemed to have, and at all times from and after the date hereof to have
had, a security interest in the proceeds of such Intellectual Property
Collateral.

      (b) The Security Interests are granted as security only and shall not
subject the Lender to, or transfer or in any way affect on modify, any
obligation or liability of the Borrower with respect to any of the Collateral in
any transaction in connection therewith

Section 4: Further Assurances, Covenants

      The Borrower covenants as follows:

      (a) The Borrower will not change (i) the location of its principal place
of business, or the location of its chief executive office or its federal tax
identification number, or (ii) the locations where it keeps or holds any
Collateral or records relating thereto from the applicable locations described
in the perfection certificate delivered by the Borrower to the Lender, or (iii)
its name, idenity or corporate structure in any manner, in each case without
giving the Lender thirty (30) day prior written notice thereof. In the event of
any such change, the Borrower shall, at its cost and expense, cooperate with the
Lender and cause to be filed or recorded additional financing statements,
amendments or supplements to existing financing statements, continuation
statements or other documents required to be recorded or filed in order to
perfect and protect the Security Interest. The Borrower shall not, in any event,
make any change if such change would cause the Security Interests in any
Collateral to lapse or cease to be perfected.

      (b) The, Borrower will, from time to time, at its expense, execute,
deliver, file and record any statement, assignment, instrument, document,
agreement or other paper and take any other action (including, without
limitation, collateral assignments of trademarks, copyright mortgages and any
filings of financing or continuation statements under the UCC) that the Lender
may from time to time reasonably determine to be necessary or desirable in order
to create, preserve, upgrade in rank (to the extent required hereby), perfect,
confirm or validate the Security Interests or to enable the Lender to obtain the
full benefits of this Agreement, or to enable the Lender to exercise and enforce
any of its rights, powers and remedies hereunder with respect to any of the
Collateral. At the request of the Lender, the Borrower will use reasonable
efforts to obtain the consent of any Person that is necessary or desirable to
effect the pledge hereunder of any right, title, claims and benefits now owned
or hereafter acquired by the Borrower in and to any Gneral Intangible. To the
extent permitted by law, the Borrower hereby authorizes the Lender to execute
and file financing statements or continuation statements without the Borrower's
signature appearing thereon. The Borrower agrees that a carbon, photographic or
other reproduction of this Agreement or of a financing statement is sufficient
as a financing statement. The Borrower shall pay the costs of, or incidental to,
any recording or filing of any financing or continuation statements concerning
the Collateral.

      (c) If any Collateral is at any time in the possession or control of any
warehouseman, bailee or of the Borrower's agents or processors, the Borrower
shall, upon the request of the Lender, notify such warehouseman, bailee, agent
or processor of the Security Interests created

                                        6

<PAGE>

hereby and to hold all such Collateral for the Lender's account subject to the
Lender's instructions.

      (d) The Borrower shall keep complete and accurate books and records
relating to the Collateral.

      (e) The Borrower will promptly deliver and pledge each Instrument to the
Lender, appropriately endorsed to the Lender without recourse, provided that so
long as no Event of Default shall have occurred and be continuing, the Borrower
may retain for collection in the ordinary course any Instruments received by
them in the ordinary course of business and the Lender shall, promptly upon
request of the Borrower, make appropriate arrangements for making any other
Instrument pledged by the Borrower available to it for purposes of presentation,
collection or renewal (any such arrangement to be effected, to the extent deemed
appropriate to the Lender, against trust receipt or like document).

      (f) The Borrower shall use its best efforts to cause to be collected from
its account debtors, as and when due, any and all amounts owing under or on
account of each Account (including, without limitation, Accounts which are
delinquent, such Accounts to be collected in accordance with lawful collection
procedures and the Borrower's standard procedures) and apply forthwith upon
receipt thereof all such amounts as are so collected to the outstanding balance
of such Account, except that, unless an Event of Default has occurred and is
continuing and the Lender is exercising its rights hereunder to collect
Accounts, the Borrower may allow in the ordinary course of business as
adjustments to amounts owing under its Accounts (i) an extension or renewal of
the time or times of payment, or settlement for less than the total unpaid
balance, which the Borrower finds appropriate in accordance with prudent
business judgment and (ii) a refund or credit due as a result of returned or
damaged merchandise, all in accordance with the Borrower's ordinary course of
business consistent with their historical collection practices. The costs and
expenses (including, without limitation, attorney's fees) of collection, whether
incurred by the Borrower or the Lender, shall be borne by the Borrower.

      (g) Upon the occurrence and during the continuance of any Event of
Default, upon the request of the Lender, the Borrower will promptly notify (and
the Borrower hereby authorizes the Lender so to notify) each account debtor in
respect of any Account or Instrument that such Collateral has been assigned to
the Lender hereunder, and that any payments due or to become due in respect of
such Collateral are to be made directly to the Lender or any designee specified
by the Lender. Following such request of the Lender, the Borrower shall hold all
proceeds from collection of Accounts as trustee for the Lender (without
commingling the same with other funds of the Borrower) and shall turn the same
over to the Lender immediately upon receipt in the identical form received (duly
endorsed by the Borrower to the Lender, if required). The Lender shall apply the
proceeds of such collections received by it to the Secured Obligations in
accordance with Section 8 of this Agreement. The application of the proceeds of
such collections shall be conditional upon the final payment in cash of the
items so collected. If any item is not so paid or the Lender is required for any
reason to return any payment made, the Lender may reverse any credit given in
respect of such item.

      (h) Without the prior written consent of the Lender, the Borrower will not
(i) sell, lease, exchange, assign or otherwise dispose of, or grant any option
with respect to, any

                                        7

<PAGE>

Collateral other than as permitted under Section 7.4 of the Credit Agreement
and, in the case of any such permitted sale or exchange, the Security Interests
created hereby in such item (but not in any Proceeds arising from such sale or
exchange) shall cease immediately without any further action on the part of the
Lender, provided, however, that at the request of the Borrower, the Lender shall
execute and deliver such UCC-3 termination statements and other documents as may
be required to release such Security Interests in such item; or (ii) create,
incur or suffer to exist any Lien with respect to any Collateral, except for
Permitted Liens and the Security Interests.

      (i) The Borrower will keep each item of Equipment in good order and repair
(with allowance for ordinary wear and tear) and will not use the same in
violation of law or any policy of insurance thereon.

      (j) The Borrower shall, (i) not later than the date of the first advance
under the Credit Agreement, in the case of Equipment now owned constituting
goods in which a security interest is perfected by a notation on the certificate
of title or similar evidence of the ownership of such goods (other than
Equipment in which the Borrower has granted Permitted Liens), (a) having a value
in excess of $100,000 or (b) having a value in excess of $50,000, if the
aggregate of such items owned by the Borrower at any time is greater than
$100,000, and (ii) within 10 days of acquiring any other similar Equipment
(other than Equipment in which the Borrower has granted Permitted Liens) (x)
having a value in excess of $ 100,000 or (y) having a value in excess of
$50,000, if the aggregate of all such items owned by the Borrower at any time is
greater than $100,000, deliver to the Lender any and all certificates of title,
applications for title or similar evidence of ownership of such Equipment and
shall cause the Lender to be named as lienholder on any such certificate of
title or other evidence of ownership. The Borrower shall not permit any
additions to the Equipment to become a fixture to real estate other than real
estate in which the Lender has been granted a first priority Lien.

      (k) The Borrower will, promptly upon request, provide to the Lender all
information and evidence it may reasonably request concerning the Collateral to
the extent such information and evidence is in the Borrower's possession
(including without limitation, the names, addresses, face value, and date of
invoices for each debtor obligated on each Account) to enable the Lender to
enforce the provisions of this Agreement and, to the extent that any such
information or evidence is not in the possession of the Borrower, the Borrower
shall make such reasonable efforts as may be required to obtain such information
or evidence.

SECTION 5. General Authority

      The Borrower hereby irrevocably appoints the Lender its true and lawful
attorney, with full power of substitution, in the name of the Borrower, the
Lender, or otherwise, for the sole use and benefit of the Lender, but at the
Borrower's expense, to the extent permitted by law to exercise, at any time and
from time to time while an Event of Default has occurred and is continuing, all
or any of the following powers with respect to all or any of the Collateral:

                  (a) to endorse the Borrower's name on any checks, notes,
            acceptances, money orders, drafts, filings or other forms of payment
            or security that may come into the Lender's possession,

                                        8

<PAGE>

                  (b) to demand, sue for, collect, receive and give acquittance
            for any and all monies due or to become due thereon or by virtue
            thereof,

                  (c) to settle, compromise, compound, prosecute or defend any
            action or proceeding with respect thereto,

                  (d) to sell, transfer, assign or otherwise deal in or with the
            same or the proceeds or avails thereof, as fully and effectually as
            if the Lender were the absolute owner thereof, and

                  (e) to extend the time of payment of any or all thereof and to
            make any allowance and other adjustments with reference thereto.

SECTION 6. Remedies upon Event of Default

      (a) If any Event of Default has occurred and is continuing, the Lender may
exercise all rights of a secured party under the UCC (whether or not in effect
in the jurisdiction where such rights are exercised) and, in addition, the
Lender may, without being required to give any notice, except as herein provided
or as may be required by law, sell the Collateral or any part thereof at public
or private sale, for cash, upon credit or for future delivery, and at such price
or prices as the Lender may deem satisfactory. The Lender may be the purchaser
of any or all of the Collateral so sold at any public sale (or, if the
Collateral is of a type customarily sold in a recognized market or is of a type
which is the subject of widely distributed standard price quotations, at any
private sale) and thereafter hold the same, absolutely, free from any right or
claim of whatsoever kind. The Lender shall give the Company not less than ten
days' prior written notice of the time and place of any sale or other intended
disposition of any of the Collateral, except any Collateral which is perishable
or threatens to decline speedily in value or is of a type customarily sold on a
recognized market. The Company agrees that such notice constitutes "reasonable
notification" within the meaning of Section 9-504(3) of the UCC. The Company
will execute and deliver such documents and take such other action as the Lender
deems necessary or advisable in order that any such sale may be made in
compliance with law. The Borrower will execute and deliver such documents and
take such other action as the Lender deems necessary or advisable in order that
any such sale may be made in compliance with law. Upon any such sale the Lender
shall have the right to deliver, assign and transfer to the purchaser thereof
the Collateral so sold. Each purchaser at any such sale shall hold the
Collateral so sold to it absolutely, free from any claim or right of whatsoever
kind, including any equity or right of redemption of the Borrower, and the
Borrower, to the extent permitted by law, hereby specifically waives all rights
of redemption, stay or appraisal which it has or may have under any law now
existing or hereafter adopted. The notice (if any) of such sale required by
Section 5 shall (A) in case of a public sale, state the time and place fixed for
such sale, and (B) in the case of a private sale, state the day after which such
sale may be consummated. Any such public sale shall be held at such time or
times within ordinary business hours and at such place or places as the Lender
may fix in the notice of such sale. At any such sale the Collateral may be sold
in one lot as an entirety or in separate parcels, as the Lender may determine.
The Lender shall not be obligated to make any such sale pursuant to any such
notice. The Lender may, without notice or publication, adjourn any public or
private sale or cause the same to be adjourned from time to time by announcement
at the time and place fixed for the sale, and such sale may be made at any

                                        9

<PAGE>

time or place to which the same may be so adjourned. In case of any sale of all
or any part of the Collateral on credit or for future delivery, the Collateral
so sold may be retained by the Lender until the selling price is paid by the
purchaser thereof, but the Lender shall not incur any liability in case of the
failure of such purchaser to take up and pay for the Collateral so sold and, in
case of any such failure, such Collateral may again be sold upon like notice.
The Lender, instead of exercising the power of sale herein conferred upon it,
may proceed by a suit or suits at law or in equity to foreclose the Security
Interests and sell the Collateral, or any portion thereof, under a judgment or
decree of a court or courts of competent jurisdiction.

      (b) For the purpose of enforcing any and all rights and remedies under
this Agrement the Lender may (i) require the Borrower to, and the Borrower
agrees that it will, at its expense and upon the request of the Lender,
forthwith assemble all or any part of the Collateral as directed by the Lender
and make it available at a place designated by the Lender which is, in its
opinion, reasonably convenient to the Lender, whether at the premises of the
Borrower or otherwise, (ii) to the extent permitted by applicable law, enter,
with or without process of law and without breach of the peace, any premises
where any of the Collateral is or may be located, and without charge or
liability to it or any Lender, seize and remove such Collateral from such
premises, (iii) have access to and use the Borrower's books and records relating
to the Collateral and (iv) prior to the disposition of the Collateral, store or
transfer it without charge in or by means of any storage or transportation
facility owned or leased by the Borrower, process, repair or recondition it or
otherwise prepare it for disposition in any manner and to the extent the Lender
deems appropriate to preserve and enhance its value and, in connection with such
preparation and disposition, use, as a licensee (or if no decline in the value
of the Collateral would result, otherwise) without charge any trademark, trade
name, copyright, patent or technical process used by the Borrower.

SECTION 7. Limitation on Duty of Lender in Respect of Collateral

      Beyond the safe custody thereof in accordance with applicable law, the
Lender shall have no duty as to any Collateral in its possession or control or
in the possession or control of any agent or bailee or any income thereon or as
to the preservation of rights against prior parties or any other rights
pertaining thereto. The Lender shall be deemed to have exercised reasonable care
in the custody and preservation of the Collateral in its possession if the
Collateral is accorded treatment substantially equal to that which it accords
its own property of like nature, arid shall not be liable or responsible for any
loss or damage to any of the Collateral, or for any diminution in the value
thereof, by reason of the act or omission of any warehouseman, carrier,
forwarding agency, consignee or other agent or bailee selected by the Lender in
good faith and in the absence of gross negligence.

SECTION 8. Application of Proceeds

      Upon the occurrence and during the continuance of an Event of Default, the
proceeds of any sale of, or other realization upon, all or any part of the
Collateral shall be applied by the Lender in the following order of priorities:

            first, to payment of the expenses of such sale or other realization,
      including reasonable compensation to the Lender and its agents and counsel
      in connection

                                       10

<PAGE>

      therewith, and all expenses, liabilities and advances incurred or made by
      the Lender in connection therewith, and any other unreimbursed expenses
      for which the Lender is to be reimbursed pursuant to the Credit Agreement
      or Section 9 hereof and unpaid fees owing to the Lender under the Credit
      Agreement;

            second, to the payment of accrued but unpaid interest on the Secured
      Obligations;

            third, to the payment of unpaid principal of the Secured
      Obligations;

            fourth, to the payment of all other Secured Obligations, until all
      Secured Obligations shall have been paid in full; and

            finally, to payment to the Borrowers or their respective successors
      or assigns, or as a court of competent jurisdiction may direct, of any
      surplus then remaining from such proceeds.

The Lender may make distributions hereunder in cash or in kind or in any
combination thereof.

SECTION 9. Expenses

      In the event that the Borrower fails to comply with the provisions of the
Credit Agreement or this Agreement, such that the value of any Collateral or the
validity, perfection, rank or value of any Security Interest is thereby
diminished or potentially diminished or put at risk, the Lender may effect such
compliance on behalf of the Borrower, and the Borrower shall reimburse the
Lender for the costs thereof within two Business Days of demand therefor. All
insurance expenses and all reasonable expenses of protecting, storing,
warehousing, appraising, insuring, handling, maintaining, and shipping the
Collateral, any and all excise, property, sales, and use taxes imposed by any
state, federal, or local authority on any of the Collateral, or in respect of
the sale or other disposition thereof, shall be borne and paid by the Borrower;
and if the Borrower fails to promptly pay any portion thereof when due, the
Lender may, at its option, but shall not be required to, pay the same and
charge the Borrower's account therefor, and the Borrower agrees to reimburse the
Lender therefor on demand. All sums so paid or incurred by the Lender for any of
the foregoing and any and all other sums for which the Borrower may become
liable hereunder and all reasonable costs and expenses (including attorneys'
fees, legal expenses and court costs) reasonably incurred by the Lender in
enforcing or protecting the Security Interests or any of their rights or
remedies under this Agreement, shall, together with interest thereon until paid
at the rate applicable to advances made under the Credit Agreement, be
additional Secured Obligations hereunder.

SECTION 10. Termination of Security Interests

      Upon the payment in full of all Secured Obligations and termination of the
Commitments, the Security Interests shall terminate and all rights to the
Collateral shall revert to the Borrower, and this Security Agreement shall
terminate and no longer be of any force and effect. After the termination of the
Security Interests pursuant to the preceding sentence and at the request of the
Borrower, the Lender shall take such action and execute and deliver to the
Borrower such UCC-3 termination statements and such other instruments as may be
required to release the Security Interests and return to the Borrower any
Collateral in its possession. If, after

                                       11

<PAGE>

the Security Interests are terminated, payment, or any part thereof, of any of
the Secured Obligations is rescinded or must otherwise be restored or returned
by the Lender upon the insolvency, bankruptcy, dissolution, liquidation or
reorganization of the Borrower or upon or as a result of the appointment of a
receiver, intervenor or conservator of, or trustee or similar officer for, the
Borrower or any substantial part of its property, or otherwise, the Security
Interests and all rights of the Lender to the Collateral shall be reinstated,
all as though such payments had not been made.

SECTION 11. Notices

      All notices, approvals, requests, demands and other communications
hereunder shall be given in accordance with the Credit Agreement.

SECTION 12. Waivers, Non-Exclusive Remedies

      No failure on the part of the Lender to exercise, and no delay in
exercising and no course of dealing with respect to, any right under the Credit
Agreement or this Agreement shall operate as a waiver thereof; nor shall any
single or partial exercise by the Lender of any right under the Credit Agreement
or this Agreement preclude any other or further exercise thereof or the exercise
of any other right. The rights in this Agreement and the Credit Agreement are
cumulative and are not exclusive of any other remedies provided by law.

SECTION 13. Successors and Assigns

      This Agreement is for the benefit of, and be enforceable by, the Lender,
and its successors and assigns, and in the event of an assignment of all or any
of the Secured Obligations, the rights, hereunder, to the extent applicable to
the indebtedness so assigned, may be transferred with such indebtedness. This
Agreement shall be binding on the Borrower and their respective successors and
assigns.

SECTION 14. Changes in Writings

      Neither this Agreement nor any provision hereof may be changed, waived,
discharged or terminated orally, but only in writing signed by the Borrower and
the Lender.

DOCUMENTS AND TO MAKE THE LOAN.

      SECTION 19. Revised Article 9 of the Uniform Commercial Code. The parties
acknowledge and agree to the following provisions of this Agreement in
anticipation of the possible application, in one or more jurisdictions, to the
transactions contemplated hereby of the revised Article 9 of the UCC in the form
or substantially in the form approved by the American Law Institute and the
National Conference of Commissioners on Uniform State Law contained in the 1999
official text of Revised Article 9 ("Revised Article 9").

      In applying the law of any jurisdiction in which Revised Article 9 is in
effect, the Collateral shall be and included all assets of the Borrower, whether
or not within the scope of Revised Article 9 with the exception of the Excluded
Property. The collateral shall include, without limitation, the following
categories of assets (as defined in Revised Article 9) belonging to the Borrower
or in which the Borrower has any rights: goods (including inventory, equipment
and any accessions thereto), instruments (including promissory notes),
documents, accounts, chattel paper (whether tangible or electronic), deposit
accounts, letter-of-credit rights (whether or not the letter of credit is
evidenced by writing), commercial tort claims, securities and all other
investment property, general intangibles (including payment intangibles and
software), supporting obligations and any and all proceeds thereof, wherever
located, whether now owned and hereafter acquired. If the Borrower shall at any
time, whether or not Revised Article 9 is in effect in any particular
jurisdiction, acquire a commercial tort claim, as defined in Revised Article 9,
the Borrower shall immediately notify the Lender in a writing signed by the
Borrower of the brief details thereof and grant to the Lender in such writing a
security interest therein and in the proceeds thereof, all upon the terms of
this Agreement, with such writing to be in form and substance satisfactory to
