<PAGE>

Section 1.2, Holder shall also deliver to the Company a check for the aggregate
Exercise Price for the Shares being purchased.

            1.2. Conversion Right. In lieu of exercising this Warrant as
specified in Section 1.1, Holder may from time to time convert this Warrant, in
whole or in part, into a number of Shares determined as follows:

                     X = Y (A-B)/A
          where
                     X = the number of Shares to be issued to the Holder

                     Y = the number of Shares with respect to which this
                     Warrant is being exercised

                     A = the Fair Market Value (as determined pursuant to
                     Section 1.3 below) of one Share

                     B = the Exercise Price

            1.3. Fair Market Value.

                  1.3.1. If shares of Common Stock are traded on a nationally
recognized securities exchange or over the counter market, the fair market value

                  1.3.2. If shares of Common Stock are not traded on a
nationally recognized securities exchange or over the counter market, the Board
of Directors of the Company shall determine the fair market value of a share of
Common Stock in its reasonable good faith judgment.

            1.4. Delivery of Certrficate and New Warrant. Promptly after Holder
exercises or converts this Warrant, the Company shall deliver to Holder

"Acquisition" means any sale, transfer, exclusive license, or other disposition
of all or substantially all of the assets of the Company, or any acquisition,

equity securities of the surviving or successor entity immediately following the
transaction.

                  1.6.2. In connection with, and upon the closing of, any
Acquisition (other than an Acquisition in which the consideration received by
the Company's stockholders consists solely of cash), and as a condition
precedent thereto, the successor or surviving entity shall assume the
obligations of this Warrant, and this Warrant thereafter shall be exercisable
for the same kind and amount of securities and other property as would be
payable for the Shares issuable upon exercise of the unexercised portion of this
Warrant as if such Shares were outstanding on the record date for the
Acquisition and subsequent closing. The Exercise Price shall be adjusted such
that the product of (i) the Exercise Price in effect immediately prior to the
closing of such Acquisition, and (ii) the number of Shares then issuable upon
exercise of this Warrant, equals the product of (i) the number of shares or
other securities or property for which this Warrant shall be exercisable
immediately following the closing of such Acquisition, and (ii) the Exercise
Price in effect immediately following the closing of such Acquisition, and the
Exercise Price and number and class of Shares shall continue to be subject to
adjustment from time to time in accordance with the provisions hereof.

ARTICLE 2. ADJUSTMENTS TO THE SHARES.

            2.1. Stock Dividends, Splits, Etc. If the Company declares or pays a
dividend on the outstanding shares of Common Stock, payable in Common Stock or
other securities, or subdivides the outstanding Common Stock into a greater
amount of Common Stock, then upon exercise of this Warrant, for each Share
acquired, Holder shall receive, without cost to Holder, the total number and
kind of securities to which Holder would have been entitled had Holder owned the
Shares of record as of the date the dividend or subdivision occurred.

            2.2. Reclassification, Exchange or Substitution. Upon any
reclassification, exchange, substitution, or other event that results in a
change of the number and/or class of the securities issuable upon exercise or
conversion of this Warrant, Holder shall be entitled to receive, upon exercise
or conversion of this Warrant, the number and kind of securities and property
that Holder would have received for the Shares if this Warrant had been
exercised immediately before such reclassification, exchange, substitution, or
other event. The Company or its successor shall promptly issue to Holder a new
Warrant for such new securities or other property. The new Warrant shall provide
for adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article 2 including, without limitation,
adjustments to the Exercise Price and to the number of securities or property
issuable upon

                                      -4-
<PAGE>

exercise of the new Warrant. The provisions of this Section 2.2 shall similarly
apply to successive reclassifications, exchanges, substitutions, or other
events.

            2.3. Adjustments for Combinations, Etc. If the outstanding shares of
Common Stock are combined or consolidated, by reclassification or otherwise,
into a lesser number of shares, the Exercise Price shall be proportionately
increased and the number of Shares shall be proportionately decreased.

            2.4. No Impairment. The Company shall not, by amendment of its
Certificate of Incorporation or by-laws, or through a reorganization, transfer
of assets, consolidation, merger, dissolution, issue, or sale of securities or
any other voluntary action, avoid or seek to avoid the observance or performance
of any of the terms to be observed or performed under this Warrant by the
Company, but shall at all times in good faith assist in carrying out of all the
provisions of this Article 2 and in taking all such action as may be necessary
or appropriate to protect Holder's rights under this Article against impairment.

            2.5. Adjustments for Diluting Issuances.

      (a) Weighted Average Adjustment. If the Company issues Additional Common
Shares after the Issue Date and the consideration per Additional Common Share
(determined pursuant to subsection (i) below) is less than the Exercise Price in
effect immediately before such Issue (a "Diluting Issuance"), the Exercise Price
shall be reduced, concurrently with such Issue, to a price (calculated to the
nearest hundredth of a cent) determined by multiplying the Exercise Price by a
fraction.

            (i) the numerator of which is the number of shares of Common Stock
outstanding immediately before such Issue plus the number of shares of Common
Stock that the aggregate consideration received by the Company for the
Additional Common Shares would purchase at the Exercise Price in effect
immediately before such Issue, and

            (ii) the denominator of which is the number of shares of Common
Stock outstanding immediately before such Issue plus the number of such
Additional Common Shares.

      (b) Adjustment to Number of Shares. Upon each adjustment of the Exercise
Price, the number of Shares issuable upon exercise of the Warrant shall be
increased to equal the quotient obtained by dividing (a) the product resulting
from multiplying (i) the number of Shares issuable upon exercise of the Warrant
and (ii) the Exercise Price, in each case as in effect immediately before such
adjustment, by (b) the adjusted Exercise Price.

      (c) Securities Deemed Outstanding. For the purpose of this Section 2.5,
all securities issuable upon exercise of any outstanding Convertible Securities
or Options, warrants, or other rights to acquire securities of the Company shall
be deemed to be outstanding.

                                      -5-
<PAGE>

      (d) No Adjustment for Issuances Following Deemed Issuances. No adjustment
to the Exercise Price shall be made upon the exercise of Options or conversion
of Convertible Securities.

      (e) Adjustment Following Changes in Terms of Options or Convertible
Securities. If the consideration payable to, or the amount of Common Stock
Issuable by, the Company increases or decreases, respectively, pursuant to the
terms of any outstanding Options or Convertible Securities, the Exercise Price
shall be recomputed to reflect such increase or decrease. The recomputation
shall be made as of the time of the Issuance of the Options or Convertible
Securities. Any changes in the Exercise Price that occurred after such Issuance
because other Additional Common Shares were Issued or deemed Issued shall also
be recomputed.

      (f) Recomputation Upon Expiration of Options or Convertible Securities.
The Exercise Price computed upon the original Issue of any Options or
Convertible Securities, and any subsequent adjustments based thereon, shall be
recomputed when any Options or rights of conversion under Convertible Securities
expire without having been exercised. In the case of Convertible Securities or
Options for Common Stock, the Exercise Price shall be recomputed as if the only
Additional Common Shares Issued were the shares of Common Stock actually Issued
upon the exercise of such Securities, if any, and as if the only consideration
received therefor was the consideration actually received upon the Issue,
exercise or conversion of the Options or Convertible Securities. In the case of
Options for Convertible Securities, the Exercise Price shall be recomputed as if
the only Convertible Securities Issued were the Convertible Securities actually
Issued upon the exercise thereof, if any, and as if the only consideration
received therefor was the consideration actually received by the Company
(determined pursuant to subsection (i)), if any, upon the Issue of the Options
for the Convertible Securities.

      (g) Limit on Readjustments. No readjustment of the Exercise Price pursuant
to Sections (e) or (f) shall increase the Exercise Price by more than the amount
of any decrease made in respect of the Issue of any Options or Convertible
Securities with respect to which such readjustment is made.

      (h) 30 Day Options. In the case of any Options that expire by their terms
not more than 30 days after the date of Issue thereof, no adjustment of the
Exercise Price shall be made until the expiration or exercise of such Options.

      (i) Computation of Consideration. The consideration received by the
Company for the Issue of any Additional Common Shares shall be computed as
follows.

            (i) Cash. shall be valued at the amount of cash received by the
Company, excluding amounts paid or payable for accrued interest or accrued
dividends.

                                      -6-
<PAGE>

            (ii) Property. Property other than cash shall be computed at the
fair market value thereof at the time of the Issue as determined in good faith
by the Board of Directors of the Company.

            (iii) Mixed Consideration. The consideration for Additional Common
Shares Issued together with other property of the Company for consideration that
covers both shall be determined in good faith by the Board of Directors.

            (iv) Options and Convertible Securities. The consideration per
Additional Common Share for Options and Convertible Securities shall be
determined by dividing.

                  (x) the total amount, if any, received or receivable by the
Company for the Issue of the Options or Convertible Securities, plus the minimum
amount of additional consideration (as set forth in the instruments relating
thereto, without regard to any provision contained therein for a subsequent
adjustment of such consideration) payable to the Company upon exercise of the
Options or conversion of the Convertible Securities, by

                  (y) the maximum amount of Common Stock (as set forth in the
instruments relating thereto, without regard to any provision contained therein
for a subsequent adjustment of such number) ultimately issuable upon the
exercise of such Options or the conversion of such Convertible Securities.

      (j) Deemed Issuance of Additional Common Shares. The shares of Common
Stock ultimately issuable upon exercise of an Option (including the shares of
Common Stock ultimately issuable upon conversion or exercise of a Convertible
Security issuable pursuant to an Option) are deemed to be Issued when the Option
is Issued. The shares of Common Stock ultimately issuable upon conversion or
exercise of a Convertible Security (other than a Convertible Security Issued
pursuant to an Option) shall be deemed Issued upon Issuance of the Convertible
Security. The maximum amount of Common Stock issuable is determined without
regard to any future adjustments permitted under the instrument creating the
Options or Convertible Securities.

            2.6. Fractional Shares. No fractional Shares shall be issuable upon
exercise or conversion of the Warrant and the number of Shares to be issued
shall be rounded down to the nearest whole Share. If a fractional Share interest
arises upon any exercise or conversion of this Warrant, the Company shall
eliminate such fractional Share interest by paying Holder an amount computed by
multiplying such fractional interest by the Fair Market Value (determined in
accordance with Section 1.3 above) of one Share.

            2.7. Certificate as to Adjustments. Upon each adjustment of the
Exercise Price, number of Shares or class of security for which this Warrant is
exercisable, the Company at its expense shall promptly compute such adjustment,
and furnish Holder with a certificate of

                                      -7-
<PAGE>

its chief financial officer setting forth such adjustment and the facts upon
which such adjustment is based. The Company shall, upon written request, furnish
Holder a certificate setting forth the Exercise Price, number of Shares and
class of security for which this Warrant is exercisable in effect upon the date
thereof and the series of adjustments leading to such Exercise Price, number of
Shares and class of security.

                                       -4-
<PAGE>

the aggregate principal amount of all loans outstanding and the requested loan
does not exceed the lesser of (i) if the amount outstanding under the Line of
Credit exceeds Six Million Dollars ($6,000,000 00), the Borrowing Base (as
defined below), or (ii) the Credit Limit (as defined below), Bank shall make
such requested loan, provided that there has not occurred and is continuing an
Event of Default or an event which, with notice or the lapse of time or both,
would constitute an Event of Default.

            (b) All loans shall bear interest and at the option of the Bank
shall be evidenced by and repayable in accordance with a revolving note drawn to
the order of Bank substantially the form of Exhibit 1 hereto (the "Master
Note"), as the same may hereafter be amended, supplemented or restated from time
to time and any note or notes issued in substitution therefor, but in the
absence of the Note shall be conclusively evidenced by Bank's records of loans
and repayments.

            Interest, net of those loans (if any) which bear interest calculated
by reference to LIBOR (as defined below), will be charged to Borrower at a
fluctuating rate which is the daily equivalent to a rate equal to the aggregate
of (x) the Prime Rate, minus (y) one (1.0%) percent per annum, or at such other
rate agreed on from time to time by the parties, upon any balance owing to Bank
at the close of each day and shall be payable (i) on the first day of each month
in arrears, (ii) on termination of this Agreement pursuant to Section 23 hereof,
(iii) on acceleration of the time for payment of the Obligations pursuant to
Section 18 hereof, and (iv) on the date the Obligations are paid in full. The
rate of interest payable by Borrower shall be changed effective as of that date
in which a change in the Prime Rate becomes effective. Interest shall be
computed on the basis of the actual number of days elapsed over a year of three
hundred sixty (360) days. The term "Prime Rate" as used herein and in any
supplement and amendment hereto shall mean the per annum rate of interest
announced from time to time by Bank, as its Prime Rate (or if Bank ceases to
announce a rate so designated, any similar successor rate designated by Bank),
it being understood that such rate is a reference rate and not necessarily the
lowest rate of interest charged by Bank. Interest shall be payable in lawful
money of the United States of America to Bank, or as Bank shall direct, without
set-off, deduction or counterclaim monthly, in arrears, on the first day of each
month, commencing on the first day of the month next succeeding the date hereof.

            Interest, net of those loans (if any) which bear interest calculated
by reference to the Prime Rate, will be charged to Borrower at a rate which is
the equivalent to the LIBOR Interest Rate (as defined below) plus Applicable
Margin (as defined below).

            (c) The term "Borrowing Base" as used herein shall mean the sum of
the following:

                  (i) Eighty (80%) percent, to be increased to ninety (90%)
      percent for any Qualified Accounts backed by letters of credit in form and
      substance, and from institutions, reasonably satisfactory to the Bank, of
      the unpaid face amount of Qualified Accounts (as defined below) or such
      other percentage thereof as may from time to time be fixed by Bank upon at
      least five (5) Business Days prior notice to Borrower, if Bank determines
      in its

                                       -5-
<PAGE>

      reasonable judgment that there has been a change in circumstances relating
      to any or all Accounts from those circumstances in existence on or prior
      to the date hereof, PLUS

                  (ii) the lesser of (A) Seven Million Five Hundred Thousand
      ($7,500,000.00) Dollars, or (B) sixty (60%) percent of the cost or market
      value, whichever is lower, of all Eligible Inventory (as defined below)
      consisting of finished goods inventory, or such other percentages of
      Eligible Inventory as may from time to time be fixed by Bank upon at least
      five (5) Business Days prior notice to Borrower, if Bank determines in its
      reasonable judgment that there has been a change in circumstances relating
      to any or all such Inventory from those circumstances in existence on or
      prior to the date hereof, MINUS

                  (iii) one hundred (100%) percent of the aggregate amount then
      undrawn on all Letters of Credit and acceptances issued pursuant to this
      Agreement for the account of the Borrower

but in no event shall the sum of all loans plus the sum of the aggregate amount
undrawn on all Letters of Credit and acceptances be in excess of the Credit
Limit.

            (d) The term "Credit Limit" as used herein shall mean an amount
equal to Twenty Million ($20,000,000.00) Dollars minus the amount then
outstanding under the Term Note (as defined below).

            (e) Borrower hereby authorizes and directs Bank, in Bank's sole
discretion (provided, however, Bank shall have no obligation to do so) (i) to
pay accrued interest as the same becomes due and payable pursuant to this
Agreement or pursuant to any note or other agreement between Borrower and Bank,
and to treat the same as a loan to Borrower, which shall be added to Borrower's
loan balance pursuant to this Agreement, (ii) to charge any amount due and
payable by Borrower to Bank hereunder to any of Borrower's accounts under the
control of Bank, or (iii) during the existence of an Event of Default, apply the
proceeds of Collateral, including, without limitation, payments on Accounts and
other payments from sales or lease of Inventory and any other funds to the
payment of such items. Bank shall promptly notify Borrower of any such charges
or applications.

            (f) The Borrowing Base formula set forth above is intended solely
for monitoring purposes. The making of loans, advances, and credits by Bank to
the Borrower in excess of the above described Borrowing Base formula is for the
benefit of the Borrower and does not affect the obligations of Borrower
hereunder, all such loans constitute Obligations and must be repaid by Borrower
in accordance with the terms of this Agreement.

            (g) At the request of the Borrower, and upon the execution of letter
of credit documentation reasonably satisfactory to Bank, up to Three Million
Dollars ($3,000,000.00) in the aggregate at any one time, and, if applicable,
within the limits of the Borrowing Base, as then computed and also within the
limits of the Credit Limit as then computed, shall issue letters of credit from
time to time by Bank for the account of the Borrower (collectively "Letters of
Credit"). The

                                       -6-
<PAGE>

Letters of Credit shall be on terms mutually acceptable to Bank and Borrower,
and unless otherwise agreed by the Bank, no Letter of Credit shall have an
expiration date later than the sooner to occur of (i) twelve (12) months from
the date of issuance of the subject Letter of Credit, or (ii) the Termination
Date. A loan in an amount equal to any amount paid by Bank under a Letter of
Credit shall be deemed made to Borrower, without request therefor, promptly upon
any payment by Bank on such Letter of Credit. In connection with the issuance of
any Letter of Credit, Borrower shall pay to Bank one and one-quarter (1.25%)
percent of the face amount of such Letter of Credit plus transaction fees at the
customary rates charged by Bank and all other normal and customary fees charged
by Bank Borrower hereby authorizes and directs Bank, in Bank's sole discretion
(provided, however, Bank shall have no obligation to do so) to pay all such fees
and costs as the same become due and payable and to treat the same as a loan to
Borrower, which shall be added to Borrower's loan balance pursuant to this
Agreement. For purposes of computing the Credit Limit, all Letters of Credit
shall be deemed to be loans.

            (h) Borrower shall pay to Bank the principal amount of all loans as
follows:

                  (i) Borrowing Base Exceeded. Whenever the outstanding
      principal balance of all loans exceed the Borrowing Base, Borrower shall
      promptly pay to Bank the excess of the outstanding principal balance of
      the loans over the Borrowing Base.

                  (ii) Payment in Full on Termination. On termination of this
      Agreement, pursuant to Section 23 or acceleration of the obligations
      pursuant to Section 18, Borrower shall pay to Bank the entire outstanding
      principal balance of all loans and shall deliver to Bank cash collateral
      in an amount equal to the aggregate of (A) amounts then undrawn on all
      outstanding Letters of Credit issued pursuant to this Agreement for the
      account of the Borrower, and (B) the amount of all outstanding acceptances
      issued pursuant to this Agreement.

            (i) Bank may, at any time and from time to time, in its reasonable
judgment upon at least five (5) Business Days prior notice to Borrower establish
reserves against the Accounts and/or the Inventory of the Borrower. The amount
of such reserves shall be subtracted from Qualified Accounts or Eligible
Inventory, as applicable, when calculating the amount of the Borrowing Base.

      6. EQUIPMENT LOAN.

Credit Limit and (II) the then outstanding balance under

                                       -7-
<PAGE>

the Line of Credit, or (ii) Two Million ($2,000,000.00) Dollars (the "Equipment

                        limitation, any purchase invoices, evidencing the
                        Borrower's intended use of the proceeds, and

                        Default existing.

collected or received in connection with the Obligations or in any communication
by Bank or any other person to the Borrower or any other person, or in the event
all or part of the principal of the Obligations or interest thereon shall be
prepaid or accelerated, so that under any of such circumstances or under any
other circumstance whatsoever the amount of interest contracted for, charged,
taken, collected, reserved, or received on the amount of principal actually
outstanding from time to time under this Agreement shall exceed the maximum
amount of interest permitted by applicable usury laws, if any, then in any such
event it is agreed as follows (i) the provisions of this paragraph shall govern
and control, (ii) neither the Borrower nor any other person or entity now or
hereafter liable for the payment of the Obligations shall be obligated to pay
the amount of such interest to the extent such interest is in excess of the
maximum amount of interest permitted by applicable usury laws, if any, (iii) any
such excess which is or has been received notwithstanding this paragraph shall
be credited against the then unpaid principal balance hereof or, if the
Obligations have been or would be paid in full by such credit, refunded to the
Borrower, and (iv) the provisions of this Agreement and the other documents or
instruments executed in connection herewith, and any communication to the
Borrower, shall immediately be deemed reformed and such excess interest reduced,
without the necessity of executing any other document, to the maximum lawful
rate allowed under applicable laws as now or hereafter construed by courts
having jurisdiction

period of the full term of the Obligations, including all prior and subsequent
renewals and extensions, all interest at any time contracted for, charged,
taken, collected, reserved or received. The terms of this paragraph shall be

a Prime Rate Loan into a LIBOR Rate Loan, unless Bank shall have received from
the Borrower a request for such LIBOR Rate Loan, in the form of Exhibit 4
annexed hereto (herein a "Notice of Borrowing"). By delivering a borrowing
request (i.e., Notice of Borrowing) to the Bank on or before 10:00 a.m., New
York time, on a Business Day, the Borrower may from time to time irrevocably
request, on not less than two nor more than five Business Days' notice, that a
LIBOR Rate Loan be made in a minimum amount of Two Hundred Fifty Thousand
($250,000.00) Dollars and integral multiples of One Hundred Thousand
($100,000.00) Dollars. On the terms and subject to the conditions of this
Agreement, each LIBOR Rate Loan shall be made available to the Borrower no later
than 11:00 a.m. New York time on the first day of the applicable. Interest
Period by deposit to the account of the Borrower as shall have been specified in
its borrowing request.

            (d) After receipt from the Borrower of any Notice of Borrowing which
requests a LIBOR Rate Loan, Bank shall determine if it is able to make such
LIBOR Rate Loan (or if it is unable to do so for reasons described in this
section only) and will notify the Borrower upon confirmation of its ability to
do so. If Bank determines in good faith that, by reason of circumstances
affecting the Interbank Market, adequate and reasonable methods do not exist for
ascertaining the LIBOR Rate which would otherwise be applicable to such LIBOR
Rate Loan, then Bank shall so notify the Borrower on or before 4:00 p.m. on the
Business Day prior to the Borrowing Date specified in the Notice of Borrowing,
and in such event, Bank shall not be obligated to make such LIBOR Rate Loan and
the Notice of Borrowing shall be deemed to have been withdrawn by the Borrower
with Bank's consent and substituted with a request for a Prime Rate Loan in an
amount equal to the requested LIBOR Rate Loan.

            (e) By delivering a continuation/conversion notice to the Bank on or
before 10:00 a.m., New York time, on a Business Day, the Borrower may from time
to time irrevocably elect, on not less than two nor more than five Business
Days' notice, that all, or any portion in an aggregate minimum amount of Two
Hundred Fifty Thousand ($250,000.00) Dollars and integral multiples of One
Hundred Thousand ($100,000.00) of any LIBOR Rate Loan be converted on the last
day of an Interest Period into a LIBOR Rate Loan with a different Interest
Period, or continued on the last day of an Interest Period as a LIBOR Rate Loan
with a similar Interest Period, provided, however, that no portion of the
outstanding principal amount of any LIBOR Rate Loans may be converted to, or
continued as, LIBOR Rate Loans when any default or Event of Default has occurred
and is continuing, and no portion of the outstanding principal amount of any
LIBOR Rate Loans may be converted to, LIBOR Rate Loans of a different duration
if such LIBOR Rate Loans relate to any Hedging Obligations. In the absence of
delivery of a continuation/conversion notice with respect to any LIBOR Rate Loan
at least two Business Days before the last day of the then current Interest

                                      -12-
<PAGE>

Period with respect thereto, such LIBOR Rate Loan shall, on such last day,
automatically convert to a loan that accrues interest by reference to the Prime
Rate.

            (f) Except as otherwise provided herein, any Notice of Borrowing
which requests a LIBOR Rate Loan shall be irrevocable and binding upon the
Borrower. In the event the Borrower fails to borrow the LIBOR Rate Loan
requested on the Borrowing Date specified in such Notice of Borrowing, the
Borrower shall indemnify Bank against any and all losses and expenses incurred
by Bank by reason of such failure including, without limiting the generality of
the foregoing, all losses and expenses incurred by reason of the liquidation,
disposition or reemployment of deposits or other funds acquired by Bank to fund
such LIBOR Rate Loan.

            (g) Interest on the outstanding principal amount of each LIBOR Rate
Loan shall accrue during the Interest Period applicable thereto at a rate equal
to the sum of the LIBOR Lending Rate for such Interest Period plus the
Applicable Margin thereto and be payable on each Interest Payment Date.

            (h) LIBOR Rate Loans shall mature and become payable in full on the
last day of the Interest Period relating to such LIBOR Rate Loan. Upon maturity,
a LIBOR Rate Loan may be continued for an additional Interest Period or may be
converted to a Prime Rate Loan, as set forth above.

            (i) LIBOR Rate Loans may be prepaid on the terms and conditions set
forth herein For LIBOR Rate Loans in connection with which the Borrower has or
may incur Hedging Obligations, additional obligations may be associated with
prepayment in accordance with the terms and conditions of the applicable Hedging
Contracts. The Borrower shall give the Bank, no later than 10:00 a.m., New York
City time, at least four (4) Business Days notice of any proposed prepayment of
any LIBOR Rate Loans, specifying the proposed date of payment of such LIBOR Rate
Loans, and the principal amount to be paid. Each partial prepayment of the
principal amount of LIBOR Rate Loans shall be in an integral multiple of Fifty
Thousand ($50,000.00) Dollars and accompanied by the payment of all charges
outstanding on such LIBOR Rate Loans and of all accrued interest on the
principal repaid to the date of payment. Borrower acknowledges that prepayment
or acceleration of a LIBOR Rate Loan during an Interest Period shall result in
the Bank incurring additional costs, expenses and/or liabilities and that it is
extremely difficult and unpractical to ascertain the extent of such costs,
expenses and/or liabilities. Therefore, all full or partial prepayments of LIBOR
Rate Loans shall be accompanied by, and the Borrower hereby promises to pay, on
each date a LIBOR Rate Loan is prepaid or the date all sums payable hereunder
become due and payable, by acceleration or otherwise, in addition to all other
sums then owing, an amount ("LIBOR Rate Loan Prepayment Fee") determined by the
Bank pursuant to the following formula:

            (i) the then 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 end of the
                Interest Period as to which prepayment is made, subtracted from

                                      -13-
<PAGE>

            (ii) the LIBOR Lending Rate plus the Applicable Margin applicable to
                 the LIBOR Rate Loan being prepaid.

            If the result of this calculation is zero or a negative number, then
there shall be no LIBOR Rate Loan Prepayment Fee. If the result of this
calculation is a positive number, then the resulting percentage shall be
multiplied by

            (iii) the amount of the LIBOR Rate Loan being prepaid.

            The resulting amount shall be divided by

            (iv) 360

            and multiplied by

            (v) the number of days remaining in the Interest Period as to which
                the prepayment is being made.

            Said amount shall be reduced to present value calculated by using
the referenced United States Treasury securities rate and the number of days
remaining on the Interest Period for the LIBOR Rate Loan being prepaid.

            The resulting amount of these calculations shall be the LIBOR Rate
Loan Prepayment Fee.

            (j) If the Bank shall determine (which determination shall, upon
notice thereof to the Borrower be conclusive and binding on the Borrower) that
the introduction of or any change in or in the interpretation of any law, rule,
regulation or guideline (whether or not having the force of law), makes it
unlawful, or any central bank or other governmental authority asserts that it is
unlawful, for the Bank to make, continue or maintain any LIBOR Rate Loan as, or
to convert any loan into, a LIBOR Rate Loan of a certain duration, the
obligations of the Bank to make, continue, maintain or convert into any such
LIBOR Rate Loans shall, upon such determination, forthwith be suspended until
the Bank shall notify the Borrower that the circumstances causing such
suspension no longer exist, and all LIBOR Rate Loans of such type shall
automatically convert into Pnme Rate Loans at the end of the then current
Interest Periods with respect thereto or sooner, if required by such law or
assertion.

            (k) If, due to payments made by the Borrower pursuant to this
Agreement or due to the acceleration of the Obligations or due to any other
reason, Bank receives payments of principal of any LIBOR Rate Loan prior to the
Maturity Date for such LIBOR Rate Loan, the Borrower shall, upon demand by Bank,
pay to Bank any amounts required to compensate Bank for any additional losses,
costs or expenses which it may reasonably incur as a result of such payment,
including, without limitation, any loss, costs or expenses incurred by reason of
the liquidation or reemployment.

                                      -14-
<PAGE>

of deposits or other funds acquired by Bank to fund or maintain such LIBOR Rate
Loans

            (l)   If the Bank shall have determined that

            (i)   US dollar deposits in the relevant amount and for the relevant
                  Interest Period are not available to the Bank in the London
                  Interbank Market,

            (ii)  by reason of circumstances affecting the Bank in the London
                  Interbank Market, adequate means do not exist for ascertaining
                  the LIBOR Rate applicable hereunder to LIBOR Rate Loans of any
                  duration, or

            (iii) the LIBOR Rate no longer adequately reflects the Bank's cost
                  of funding loans.

            Then, upon notice from the Bank to the Borrower, the obligations of
the Bank to make or continue any loans as, or to convert any loans into, LIBOR
Rate Loans of such duration shall forthwith be suspended until the Bank shall
notify the Borrower that the circumstances causing such suspension no longer
exist.

            (m) In addition to the LIBOR Rate Loan Prepayment Fee, the Borrower
agrees to reimburse the Bank (without duplication) for any increase in the cost
to the Bank, or reduction in the amount of any sum receivable by the Bank, in
respect, or as a result of,

            (i)   any conversion or repayment or prepayment of the principal
                  amount of any LIBOR Rate Loans on a date other than the
                  scheduled last day of the Interest Period applicable thereto,

            (ii)  any loans not being made as LIBOR Rate Loans in accordance
                  with the borrowing request thereof,

            (iii) any LIBOR Rate Loans not being continued as, or converted
                  into, LIBOR Rate Loans in accordance with the
                  continuation/conversion notice thereof, or

            (iv)  any costs associated with marking to market any Hedging
                  Obligations that (in the reasonable determination of the Bank)
                  are required to be terminated as a result of any conversion,
                  repayment or prepayment of the principal amount of any LIBOR
                  Rate Loan on a date other than the scheduled last day of the
                  Interest Period applicable thereto,

            The Bank shall promptly notify the Borrower in writing of the
occurrence of any such event, such notice to state, in reasonable detail, the
reasons therefor and the additional amount required fully to compensate the Bank
for such increased cost or reduced amount. Such additional

                                      -15-
<PAGE>

amounts shall be payable by the Borrower to the Bank within five days of its
receipt of such notice, and such notice shall, in the absence of manifest error,
be conclusive and binding on the Borrower. The Borrower understands, agrees and
acknowledges the following (a) the Bank does not have any obligation to
purchase, sell and/or match funds in connection with the use of LIBOR Rate as a
basis for calculating the rate of interest on a LIBOR Rate Loan, (b) the LIBOR
Rate may be used merely as a reference in determining such rate, and (c) the
Borrower has accepted the LIBOR Rate as a reasonable and fair basis for
calculating such rate, the LIBOR Rate Prepayment Fee, and other funding losses
incurred by the Bank. Borrower further agrees to pay the LIBOR Rate Prepayment
Fee and other funding losses, if any, whether or not the Bank elects to
purchase, sell and/or match funds.

            (n) If on or after the date hereof the adoption of any applicable
law, rule or regulation or guideline (whether or not having the force of law),
or any change therein, or any change in the interpretation or administration
thereof by any governmental authority, central bank or comparable agency charged
with the interpretation or administration thereof, or compliance by the Bank
with any request or directive (whether or not having the force of law) of any
such authority, central bank or comparable agency:

            (i)   shall subject the Bank to any tax, duty or other charge with
                  respect to its LIBOR Rate Loans or its obligation to make
                  LIBOR Rate Loans, or shall change the basis of taxation of
                  payments to the Bank of the principal of or interest on its
                  LIBOR Rate Loans or any other amounts due under this Agreement
                  in respect of its LIBOR Rate Loans or its obligation to make
                  LIBOR Rate Loans (except for the introduction of, or change in
                  the rate of, tax on the overall net income of the Bank or
                  franchise taxes, imposed by the jurisdiction (or any political
                  subdivision or taxing authority thereof) under the laws of
                  which the Bank is organized or in which the Bank's principal
                  executive office is located), or

            (ii)  shall impose, modify or deem applicable any reserve, special
                  deposit or similar requirement (including, without limitation,
                  any such requirement imposed by the Board of Governors of the
                  Federal Reserve System of the United States) against assets
                  of, deposits with or for the account of, or credit extended
                  by, the Bank or shall impose on the Bank or on the London
                  Interbank Market any other condition affecting its LIBOR Rate
                  Loans or its obligation to make LIBOR Rate Loans,

and the result of any of the foregoing is to increase the cost to the Bank of
making or maintaining any LIBOR Rate Loan, or to reduce the amount of any sum
received or receivable by the Bank under this Agreement with respect thereto, by
an amount deemed by the Bank to be material, then the Bank shall notify the
Borrower thereof within a reasonable time after the occurrence thereof and,
within fifteen (15) days after demand by the Bank, the Borrower shall pay to the
Bank such additional amount or amounts as will compensate the Bank for such
increased cost or reduction.

                                      -16-
<PAGE>

            (o) All payments by the Borrower of principal of, and interest on,
the LIBOR Rate Loans and all other amounts payable hereunder shall be made free
and clear of and without deduction for any present or future income, excise,
stamp or franchise taxes and other taxes, fees, duties, withholdings or other
charges of any nature whatsoever imposed by any taxing authority, but excluding
franchise taxes and taxes imposed on or measured by the Bank's net income or
receipts (such non-excluded items being called "Taxes"). In the event that any
withholding or deduction from any payment to be made by the Borrower hereunder
is required in respect of any Taxes pursuant to any applicable law, rule or
regulation, then the Borrower will:

            (i)   pay directly to the relevant authority the full amount
                  required to be so withheld or deducted,

            (ii)  promptly forward to the Bank an official receipt or other
                  documentation reasonably satisfactory to the Bank evidencing
                  such payment to such authority, and

            (iii) pay to the Bank such additional amount or amounts as is
                  necessary to ensure that the net amount actually received by
                  the Bank will equal the full amount the Bank would have
                  received had no such withholding or deduction been required.

            Moreover, if any Taxes are directly asserted against the Bank with
respect to any payment received by the Bank hereunder, the Bank may pay such
Taxes and the Borrower will promptly pay such additional amount (including any
penalties, interest or expenses) as is necessary in order that the net amount
received by the Bank after the payment of such Taxes (including any Taxes on
such additional amount) shall equal the amount the Bank would have received had
not such Taxes been asserted.

            If the Borrower fails to pay any Taxes when due to the appropriate
taxing authority or fails to remit to the Bank the required receipts or other
required documentary evidence, the Borrower shall indemnify the Bank for any
incremental Taxes, interest or penalties that may become payable by the Bank as
a result of any such failure.

            (p) Notwithstanding anything to the contrary contained herein, Bank
and Borrower agree that after the occurrence of an Event of Default which is
continuing, Borrower shall not request and Bank will not make LIBOR Rate Loan.

            (q) Without derogating from any rights of the Bank, Borrower shall
pay a late charge equal to five (5%) percent of any amounts not paid when due.

            (s) All payments shall be applied first to the payment of all fees,
expenses and other amounts due to the Bank (excluding principal and interest),
then to accrued interest, and the balance on account of outstanding principal,
provided, however, that after an Event of Default, payments will be applied to
the obligations of Borrower to Bank as Bank determines in its sole discretion.

      8 DEFINITION OF QUALIFIED ACCOUNT The term "Qualified Account", as used
herein, means an Account owing to Borrower which met the following
specifications at the time it came into existence and continues to meet the same
until it is collected in full, unless otherwise agreed by the Bank and the

the invoice thereof.

            (b) The Account arose from the performance of services or an
outright sale of goods by Borrower, such goods have been shipped to the account
debtor, and Borrower has possession of, or has delivered to Bank, shipping and
delivery receipts evidencing such shipment.

            (c) The Account is not subject to any prior assignment, claim, lien,
or security interest, and Borrower will not make any further assignment thereof
or create any further security interest therein, nor permit Borrower's rights
therein to be reached by attachment, levy, garnishment or other judicial
process.

            (d) The Account is not subject to set-off, credit, allowance or
adjustment by the account debtor, except discount allowed for prompt payment and
the account debtor has not complained as to his liability thereon and has not
returned any of the goods from the sale of which the Account arose.

            (e) The Account arose in the ordinary course of Borrower's business
and did not arise from the performance of services or a sale of goods to a
supplier or employee of the Borrower.

            (f) No notice of bankruptcy or insolvency of the account debtor has
been received by or is known to the Borrower.

            (g) The Account is not owed by an account debtor whose principal
place of business is outside the United States of America, which are not
supported by credit insurance in form and substance reasonably satisfactory to
the Bank.

            (h) The Account is not owed by an entity which is a parent,
brother/sister, subsidiary or affiliate of Borrower.

                                      -18-
<PAGE>

            (i) The account debtor is not located in the State of New Jersey or
in the State of Minnesota (or any other state that requires an entity to file a
business activity report or similar document in order to bring suit or otherwise
enforce its remedies against an account debtor in the courts or through any
judicial process of such state), unless (i) Borrower has filed and shall file
all legally required Notice of Business Activities Reports with the New Jersey
Division of Taxation or the Minnesota Department of Revenue, as the case may be,
or (ii) Borrower is exempt from such filing requirement.

            (j) The Account when aggregated with all of the Accounts of that
account debtor does not exceed fifty (50%) percent of the then aggregate of
Qualified Accounts.

completion of the order therefor.

            (n) Bank has not notified Borrower that Bank, in accordance with its
normal credit policies, has deemed the Account to be unacceptable for any
reason.

PROVIDED THAT if at any time fifty (50%) percent or more of the aggregate amount
of the Accounts due from any account debtor are unpaid in whole or in part more
than ninety (90) days from the respective dates of invoice, from and after such
time none of the Accounts (then existing or hereafter arising) due from such
account debtor shall be deemed to be Qualified Accounts until such time as all
Accounts due from such account debtor are (as a result of actual payments
received thereon) no more than ninety (90) days from the date of invoice,
Accounts payable by Borrower to an account debtor shall be netted against
Accounts due from such account debtor and the difference (if positive) shall
constitute Qualified Accounts from such account debtor for purposes of
determining the Borrowing Base (notwithstanding paragraph (d) above),
characterization of any Account due from an account debtor as a Qualified
Account shall not be deemed a determination by Bank as to its actual value nor
in any way obligate Bank to accept any Account subsequently arising from such
account debtor to be, or to continue to deem such Account to be, a Qualified
Account, it is Borrower's responsibility to determine the creditworthiness of
account debtors and all risks concerning the same and collection of Accounts are
with Borrower, and all Accounts whether or not Qualified Accounts constitute
Collateral.

      9 DEFINITION OF ELIGIBLE INVENTORY The term "ELIGIBLE INVENTORY", AS used

Borrower in accordance with the Federal Fair Labor Standards Act of 1938, as
amended, and all rules, regulations and orders promulgated thereunder, not
stored with a bailee, warehouseman or similar party unless Bank has given its
prior written consent thereto and Borrower has caused each such bailee,
warehouseman or similar party to issue and deliver to Bank warehouse receipts in
Bank's name for such Inventory, and have not been designated by Bank (with
notice thereof to Borrower), in accordance with its normal credit policies, as
unacceptable for any reason by notice to Borrower.

      12    CAPITAL ADEQUACY

            If any change in, or the introduction, adoption, effectiveness,

directive, guideline, decision or request (whether or not having the force of
law) of any court, central bank, regulator or other governmental authority
affects or would affect the amount of capital required or expected to be
maintained by the Bank, or person controlling the Bank, and the Bank determines
(in its sole and absolute discretion) that the rate of return on its or such
controlling person's capital as a consequence of its commitments or the loans
made by the Bank is reduced to a level below that which the Bank or such
controlling person could have achieved but for the occurrence of any such
circumstance, then, in any such case, the Bank shall notify the Borrower thereof
within a reasonable time after the occurrence thereof and upon such notice from
time to time by the Bank to the Borrower, the Borrower shall promptly pay
directly to the Bank additional amounts sufficient to compensate the Bank or
such controlling person for such reduction in rate of return. A statement of the
Bank as to any such additional amount or amounts (including calculations thereof
in reasonable detail) shall, in the absence of manifest error, be conclusive and
binding on the Borrower. In determining such amount, the Bank may use any method
of averaging and attribution that it (in its sole and absolute discretion) shall
deem applicable.

      13    COLLECTIONS, SET OFF, DEPOSIT ACCOUNTS, NOTICE OF ASSIGNMENT,
            EXPENSES, POWER OF ATTORNEY

            (a) Borrower will promptly, upon receipt of all checks, drafts, cash
and other remittances in payment of any Inventory sold or in payment or on
account of Borrower's accounts, contracts, contract rights, notes, bills,
drafts, acceptances, general intangibles, chooses in action and all other forms
of obligations, deliver the same to Bank accompanied by a remittance report in
form specified by Bank. Said proceeds shall be delivered to Bank in the same
form received except for the endorsement of Borrower where necessary to permit
collection of items, which endorsement Borrower agrees to make Bank will credit
(conditional upon final collection) all such payments against the principal or
interest of any loans secured hereby. The order and method of such application
shall be in the sole discretion of Bank and any portion of such funds which Bank
elects not to so apply shall be paid over from time to time by Bank to Borrower
Bank will at all times have the right to require Borrower (i) to enter into a
lockbox arrangement with Bank for the collection of such remittances and
payments, or (ii) to maintain its deposit accounts at Bank or, in the
alternative, at another financial institution which has agreed to accept drafts
drawn on it by Bank under a written depository transfer agreement with Bank and
to block Borrower's account and waive its rights as against such account.
Notwithstanding anything contained to the contrary herein, said proceeds shall
not be applied to the principal of any LIBOR Rate Loan(s), until all Prime Rate
Loans have been paid in full. As used in this section, "business day(s)" shall
mean any day which is neither a Saturday, Sunday nor holiday on which commercial
banks are authorized or required to be closed in Boston, Massachusetts.

            (b) Borrower or any guarantor hereby grant to Bank a lien, security
interest and right of setoff as security for all liabilities and Obligations to
Bank, 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 Bank or any entity in the control of Bank of America
Corporation, or in transit to any of them. At any time during an Event of
Default, without demand or notice, Bank may set off the same or any part thereof
and apply the same to any liability or Obligation of Borrower or any guarantor
even though unmatured and regardless of the adequacy of any other collateral
securing the Obligations. ANY AND ALL RIGHTS TO REQUIRE BANK TO EXERCISE ITS
RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH SECURES THE
OBLIGATIONS, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH
DEPOSITS, CREDITS OR OTHER PROPERTY OF BORROWER OR ANY GUARANTOR, ARE HEREBY
KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED.

            (c) Bank shall be Borrower's main bank of deposit. Borrower shall
maintain aggregate collected funds on deposit with the Bank of at least Two
Million ($2,000,000.00) Dollars. Borrower shall maintain with the Bank at least
fifty (50%) percent of their invested assets. For each deposit account that
Borrower at any time opens or maintains, Borrower shall, at Bank's reasonable
request and option, pursuant to an agreement in form and substance reasonably
satisfactory to Bank, either (i) cause the depositary bank to agree to comply at
any time with instructions from Bank to

                                      -23-
<PAGE>

such depositary bank directing the disposition of funds from time to time
credited to such deposit account, without further consent of Borrower, or (ii)
arrange for Bank to become the customer of the depositary bank with respect to
the deposit account, with Borrower being permitted, only with the consent of
Bank, to exercise rights to withdraw funds from such deposit account. Bank
agrees with Borrower that Bank shall not give any such instructions or withhold
any withdrawal rights from Borrower, unless an Event of Default has occurred and
is continuing, or, after giving effect to any withdrawal not otherwise permitted
by this Agreement would occur. The provisions of this paragraph shall not apply
to (i) any deposit account for which Borrower, the depositary bank and Bank have
entered into a cash collateral agreement specially negotiated among Borrower,
the depositary bank and Bank for the specific purpose set forth therein, or (ii)
deposit accounts specially and exclusively used for payroll, payroll taxes and
other employee wage and benefit payments to or for the benefit of Borrower's
salaried employees.

            (d) Bank may at any time, after the occurrence and during the
continuance of an Event of Default or an event which, with notice or the passage
of time or both, would constitute an Event of Default, notify account debtors
that Collateral has been assigned to Bank and that payments shall be made
directly to or as directed by Bank. Upon request of Bank at any such time,
Borrower will so notify such account debtors and will indicate on all billings
to such account debtors that their Accounts must be paid directly to or as
directed by Bank. At any such time, Bank shall have full power to collect,
compromise, endorse, sell or otherwise deal with the Collateral or proceeds
thereof in its own name or in the name of Borrower.

            (e) Borrower shall pay to Bank on demand any and all reasonable
counsel fees and other expenses reasonably incurred by Bank in connection with
the preparation, interpretation, enforcement, administration or amendment of
this Agreement, or of any documents relating thereto, (provided that Bank's
counsel fees in connection with the preparation of this Agreement and all
documents relating thereto shall not exceed $10,000.00) and any and all
expenses, including, but not limited to, a collection charge on all Accounts
collected, all attorneys' fees and expenses, and all other expenses of like or
unlike nature which may be expended by Bank to obtain or enforce payment of any
Account either as against the account debtor, Borrower, or any guarantor or
surety of Borrower or in the prosecution or defense of any action or concerning
any matter growing out of or connected with the subject matter of this
Agreement, the Obligations or the Collateral or any of Bank's rights or
interests therein or thereto, including, without limiting the generality of the
foregoing, any counsel fees or expenses incurred in any bankruptcy or insolvency
proceedings and all costs and expenses incurred or paid by Bank in connection
with the administration, supervision, protection or realization on any security
held by Bank for the debt secured hereby, whether such security was granted by
Borrower or by any other person primarily or secondarily liable (with or without
recourse) with respect to such debt, and all costs and expenses incurred by Bank
in connection with the defense, settlement or satisfaction of any action, claim
or demand asserted against Bank in connection with the debt secured hereby, all
of which amounts shall be considered advances to protect Bank's security, and
shall be secured hereby. At its option, and without limiting any other rights or
remedies, Bank may at any time pay or discharge any taxes, liens, security
interests or other encumbrances at any time levied against or placed on any of
the Collateral, and

                                      -24-
<PAGE>

may procure and pay any premiums on any insurance required to be carried by
Borrower, and provide for the maintenance and preservation of any of the
Collateral, and otherwise take any action reasonably deemed necessary to Bank to
protect its security, and all amounts expended by Bank in connection with any of
the foregoing matters, including reasonable attorneys' fees, shall be considered
obligations of Borrower and shall be secured hereby.

            (f) Borrower does hereby make, constitute and appoint any officer or
agent of Bank as Borrower's true and lawful attorney-in-fact, with power during
an Event of Default to endorse the name of Borrower or any of Borrower's
officers or agents upon any notes, checks, drafts, money orders, or other
instruments of payment (including payments payable under any policy of insurance
on the Collateral) or Collateral that may come into possession of Bank in full
or part payment of any amounts owing to Bank, to sign and endorse the name of
Borrower or any of Borrower's officers or agents upon any invoice, freight or
express bill, bill of lading, storage or warehouse receipts, drafts against
debtors, assignments, verifications and notices in connection with Accounts, and
any instrument or documents relating thereto or to Borrower's rights therein, to
give written notice to such office and officials of the United States Post
Office to effect such change or changes of address so that all mail addressed to
Borrower may be delivered directly to Bank, granting upon Borrower's said
attorney full power to do any and all things necessary to be done in and about
the premises as fully and effectually as Borrower might or could do, and hereby
ratifying all that said attorney shall lawfully do or cause to be done by virtue
hereof. Neither Bank nor the attorney shall be liable for any acts or omissions
nor for any error of judgment or mistake, except for their gross negligence or
willful misconduct. This power of attorney shall be irrevocable for the term of
this Agreement and all transactions hereunder and thereafter as long as Borrower
may be indebted to Bank.

      14 FINANCING STATEMENTS. At the request of Bank, Borrower will join with
Bank in executing one or more Financing Statements pursuant to the Uniform
Commercial Code or other notices appropriate under applicable law in form
reasonably satisfactory to Bank and will pay the cost of filing the same in all
public offices wherever filing is deemed by Bank to be necessary or desirable. A

at any time and from time to time to file in any Uniform Commercial Code
jurisdiction any initial financing statements and amendments thereto that (a)
indicate the Collateral (i) as all assets of Borrower other than Intellectual

      16    GENERAL AGREEMENTS OF BORROWER

            (a) Borrower agrees to keep all the Collateral insured with coverage
and in amounts not less than that usually carried by one engaged in a like
business and in any event not less than that reasonably required by Bank with
loss payable to Bank and Borrower, as their interests may appear (provided that
so long as no Event of Default exists, any amounts received by Bank shall be
promptly forwarded to Borrower), hereby appointing Bank as attorney for Borrower
during an Event of Default in obtaining, adjusting, settling and canceling such
insurance and endorsing any drafts. As further assurance for the payment and
performance of the Obligations, Borrower hereby assigns to Bank all sums,
including returns of unearned premiums, which may become payable during an Event
of Default under any policy of insurance on the Collateral and Borrower hereby
directs each insurance company issuing any such policy to make payment of such
sums directly to Bank.

            (b) Bank or its agents have the right to inspect the Collateral and
all records pertaining thereto at intervals to be determined by Bank during
Borrower's regular business hours upon reasonable prior notice but without
notice any time while an Event of Default exists and without hindrance or delay.
Bank shall also have the right to obtain from time to time upon its reasonable
request at the sole cost and expense of Borrower an appraisal of the Collateral
by an appraiser reasonably acceptable to Bank.

                                      -27-

            (c) Although, as above set forth, Bank has a continuing security
interest in all of Borrower's Collateral and in the proceeds thereof, Borrower
will at all times maintain as the minimum security hereunder a Borrowing Base
not less than the aggregate unpaid principal of all loans made hereunder and if
Borrower fails to do so, Borrower will promptly make the necessary reduction in
the unpaid principal amount of said loans so that the loans outstanding
hereunder do not in the aggregate exceed the Borrowing Base.

            (d) Borrower will at all times keep accurate and complete records of
Borrower's Inventory, Accounts and other Collateral, and Bank, or any of its
agents, shall have the right to call at Borrower's place or places of business
at intervals to be determined by Bank during Borrower's regular business hours
upon reasonable prior notice but without notice any time while an Event of
Default exists, and without hindrance or delay, to inspect, audit, check, and
make extracts from any copies of the books, records, journals, orders, receipts,
correspondence which relate to Borrower's Accounts, and other Collateral or
other transactions, between the parties thereto and the general financial
condition of Borrower and Bank may remove any of such records temporarily for
the purpose of having copies made thereof. Borrower shall pay to Bank all
reasonable audit fees (not to exceed $5,000.00 in any calendar year, absent an
Event of Default which is continuing), plus all travel and other expenses
incurred in connection with any such audit.

            (e) Borrower will maintain a standard and modern system of
accounting which enables Borrower to produce financial statements in accordance
with generally accepted accounting principles and maintain records pertaining to
the Collateral that contain information as from time to time may be reasonably
requested by Bank.

            (f) Borrower will maintain its corporate existence in good standing
and comply with all laws and regulations of the United States or of any state or
states thereof or of any political subdivision thereof, or of any governmental
authority which may be applicable to it or to its business.

            (g) Borrower will pay all real and personal property taxes,
assessments and charges and all franchises, income, unemployment, old age
benefits, withholding, sales and other taxes assessed against it, or payable by
it at such times and in such manner as to prevent any penalty from accruing or
any lien or charge from attaching to its property.

            (h) After consultation with Borrower, Bank may in its own name or in
the name of others communicate with account debtors in order to verify with them
to Bank's reasonable satisfaction the existence, amount and terms of any
Accounts.

            (i) This Agreement may but need not be supplemented by separate
assignments of Accounts and if such assignments are given the rights and
security interests given thereby shall be in addition to and not in limitation
of the rights and security interests given by this Agreement.

            (j) If any of Borrower's Accounts arise out of contracts with the
United States or

                                      -28-
<PAGE>

any department, agency, or instrumentality thereof, Borrower will promptly
notify Bank thereof in writing and while an Event of Default exists execute any
instruments and take any steps required by Bank in order that all monies due and
to become due under such contracts shall be assigned to Bank and notice thereof
given to the Government under the Federal Assignment of Claims Act.

            (k) If any of Borrower's Accounts should be evidenced by promissory
notes, trade acceptances, or other instruments for the payment of money,
Borrower will promptly deliver same to Bank, appropriately endorsed to Bank's
order and, regardless of the form of such endorsement, Borrower hereby waives
presentment, demand, notice of dishonor, protest and notice of protest and all
other notices with respect thereto.

            (l) If any goods are at any time in the possession of a bailee,
Borrower shall promptly notify Bank thereof and, if reasonably requested by
Bank, shall promptly obtain an acknowledgment from the bailee, in form and
substance reasonably satisfactory to Bank, that the bailee holds such Collateral
for the benefit of Bank and shall act upon the instructions of Bank, without the
further consent of Borrower, during an Event of Default. Bank agrees with
Borrower that Bank shall not give any such instructions unless an Event of
Default has occurred and is continuing or would occur after taking into account
any action by Borrower with respect to the bailee.

            (m) If Borrower is at any time a beneficiary under a letter of
credit now or hereafter issued in favor of Borrower, Borrower shall promptly
notify Bank thereof and, at the reasonable request and option of Bank, Borrower
shall, pursuant to an agreement in form and substance reasonably satisfactory to
Bank, either (i) arrange for the issuer and any confirmer of such letter of
credit to consent to an assignment to Bank of the proceeds of any drawing under
the letter of credit, or (ii) arrange for Bank to become the transferee
beneficiary of the letter of credit, with Bank agreeing, in each case, that the
proceeds of any drawing under the letter of credit are to be applied in the same
manner as any other payment on an Account.

            (n) If Borrower shall at any time hold or acquire a commercial tort
claim, Borrower shall promptly notify Bank in a writing signed by Borrower of
the brief details thereof and grant to Bank 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 reasonably satisfactory to Bank.

            (o) Borrower will promptly pay when due all taxes and assessments
upon the Collateral or for its use or operation or upon this Agreement, or upon
any note or notes evidencing the Obligations, and will, at the reasonable
request of Bank, promptly furnish Bank the receipted bills therefor. At its
option, Bank may discharge taxes, liens or security interests or other
encumbrances at any time levied or placed on the Collateral, may pay for
insurance on the Collateral and may pay for the maintenance and preservation of
the Collateral. Borrower agrees to reimburse Bank on demand for any payments
made, or any expenses incurred by Bank pursuant to the foregoing authorization,
and upon failure of the Borrower so to reimburse Bank, any such sums paid

                                      -29-
<PAGE>

or advanced by Bank shall be deemed secured by the Collateral and constitute
part of the Obligations.

            (p) Borrower will promptly notify Bank upon receipt of notification
of any potential or known release of hazardous materials, hazardous waste,
hazardous or toxic substance or oil from any site operated by Borrower or of the
incurrence of any expense or loss in connection therewith or with the Borrower's
obtaining knowledge of any investigation, action or the incurrence of any
expense or loss by any governmental authority in connection with the assessment,
containment or removal of any hazardous material or oil for which expense or
loss the Borrower may be liable. As used herein, the terms "hazardous waste,"
"hazardous or toxic substance," "hazardous material" or "oil" shall have the
same meanings as defined and used in any of the following (the "Acts") the
Comprehensive Environmental Response, Compensation and Liability Act of 1980, 42
USC Sections 9601-9657, as amended by the Superfund Accounts and Reauthorization
Act of 1986, the Federal Resource Conservation and Recovery Act, 42 USC Sections
6901 et seq, the Hazardous Materials Transportation Act, 49 USC Sections 1801 et
seq, the Toxic Substances Control Act, 15 USC Sections 2601 et seq, the Federal
Water Pollution Control Act, 33 USC Sections 1251 et seq, the Clean Air Act, 42
USC Sections 741 et seq, the Clean Water Act, 33 USC Section 701, the Safe
Drinking Water Act, 42 USC Sections 300(f)-300(j), M.G.L.A.c 21E (Massachusetts
Oil and Hazardous Material Release Prevention Act), M.G.L.A.c 21C (Massachusetts
Hazardous Waste Management Act), and/or the regulations adopted and publications
promulgated pursuant to any of the Acts, as the same may be amended from time to
time.

            (q) Except for Bank's gross negligence or willful misconduct or
failure to comply with this Agreement, Borrower will indemnify and save Bank
harmless from all loss, costs, damage, liability or expenses (including, without
limitation, court costs and reasonable attorneys' fees) that Bank may sustain or
incur by reason of defending or protecting this security interest or the
priority thereof or enforcing the Obligations, or in the prosecution or defense
of any action or proceeding concerning any matter growing out of or in
connection with this Agreement and/or any other documents now or hereafter
executed in connection with this Agreement and/or the Obligations and/or the
Collateral. This indemnity shall survive the repayment of the Obligations and
the termination of Bank's agreement to make loans available to Borrower and the
termination of this Agreement.

            (r) Upon the reasonable request of Bank, Borrower will furnish to
Bank, from time to time, within five (5) days after the accrual in accordance
with applicable law of Borrower's obligation to make deposits for F.I.C.A. and
withholding taxes and/or sales taxes, proof reasonably satisfactory to Bank that
such deposits have been made as required.

            (s) Should Borrower fail to make any of such deposits or furnish
such proof then Bank may, in its sole and absolute discretion, (a) make any of
such deposits or any part thereof, (b) pay such taxes, or any part thereof, or
(c) set-up such reserves as Bank, in its judgment, shall deem necessary to
satisfy the liability for such taxes. Each amount so deposited or paid shall
constitute an advance under the terms hereof, repayable on demand with interest,
as provided herein, and secured

                                      -30-
<PAGE>

by all Collateral and any other property at any time pledged by Borrower with
Bank. Nothing herein shall be deemed to obligate Bank to make any such deposit
or payment or set-up such reserve and the making of one or more of such deposits
or payments or the setting-up of such reserve shall not constitute (i) an
agreement on Bank's part to take any further or similar action, or (ii) a waiver
of any default by Borrower under the terms hereof.

            (t) All advances by Bank to Borrower under this Agreement and under
any other agreement constitute one general revolving fluctuating loan, and all
indebtedness of Borrower to Bank under this and under any other agreement
constitute one general Obligation. Each advance to Borrower hereunder or
otherwise shall be made upon the security of all of the Collateral held and to
be held by Bank. It is distinctly understood and agreed that all of the rights
of Bank contained in this Agreement shall likewise apply, insofar as applicable,
to any modification of or supplement to this Agreement and to any other
agreements between Bank and Borrower. Any default of this Agreement by Borrower
shall constitute, likewise, a default by Borrower of any other existing
agreement with Bank, and any default by Borrower of any other agreement with
Bank shall constitute a default of this Agreement. The entire Obligation of
Borrower to Bank shall become due and payable upon termination of this
Agreement.

            (u) Borrower hereby grants to Bank for a term to commence on the
date of this Agreement and continuing thereafter until all debts and Obligations
of any kind or character owing from Borrower to Bank are fully paid and
discharged, the right to use all premises or places of business which Borrower
presently has or may hereafter have and where any of the Collateral may be
located, at a total rental for the entire period of $ 1.00 Bank agrees not to
exercise the rights granted in this paragraph unless and until Bank determines
to exercise its rights against the Collateral.

            (v) Borrower will, at its expense, upon the reasonable request of
Bank promptly and duly execute and deliver such documents and assurances and
take such actions as may be necessary or desirable or as Bank may reasonably
request in order to correct any defect, error or omission which may at any time
be discovered or to more effectively carry out the intent and purpose of this
Agreement and to establish, perfect and protect Bank's security interest, rights
and remedies created or intended to be created hereunder. Without limiting the
generality of the above, Borrower will join with Bank in executing financing and
continuation statements pursuant to the Uniform Commercial Code or other notices
appropriate under applicable Federal or state law in form reasonably
satisfactory to Bank and filing the same in all public offices and jurisdictions
wherever and whenever reasonably requested by Bank.

            (w) Borrower shall perform any and all further steps reasonably
requested by Bank to perfect Bank's security interest in Inventory, such as
leasing warehouses to Bank or its designee, placing and maintaining signs,
appointing custodians, maintaining stock records and transferring Inventory to
warehouses. A physical listing of all Inventory, wherever located, shall be
taken by Borrower at least annually and whenever requested by Bank if one or
more of the Events of Default exist.

                                      -31-
<PAGE>

            (x) Borrower hereby grants to Bank for a term to commence on the
date of this Agreement and continuing thereafter until all debts and Obligations
of any kind or character owed to Bank are fully paid and discharged, a
non-exclusive irrevocable royalty-free license in connection with Bank's
exercise of its rights hereunder, to use, apply or affix any trademark, trade
name logo or the like and to use any patents, in which the Borrower now or
hereafter has rights, which license may be used by Bank upon and after the
occurrence of any one or more of the Events of Default, provided, however, that
such use by Bank shall be suspended if such Events of Default are cured.

more of the following events (herein, "Events of Default"), Bank may decline to
make any or all further loans or issue Letters of Credit hereunder or under any
other agreements with Borrower, any and all Obligations of the Borrower to Bank
shall become immediately due and payable, at the option of Bank and without
notice or demand. The occurrence and continuance of any such Event of Default
shall also constitute, without notice or demand, a default under all other

by the Borrower, whether such agreements, instruments, or papers now exist or
hereafter arise, namely.

      be contested by the Borrower.

                  (xxiv) Any of the following events occur or exist with respect
      to the Borrower or any ERISA affiliate (A) any "prohibited transaction"
      (as defined in Section 406 of ERISA or Section 4975 of the Internal
      Revenue Code) involving any Plan, (B) any "reportable event" (as defined
      in Section 4043 of ERISA and the regulations issued under such Section)

      ERISA of a notice of intent to terminate any Plan or the termination of

      events or conditions, if any, could in the opinion of Bank subject the
      Borrower to any tax, penalty, or other liability to a Plan, a
      Multiemployer Plan, the PBGC, or otherwise.

                  Upon the occurrence and during the continuance of an Event of
      Default, Bank may declare any obligation Bank may have hereunder to be
      cancelled, declare all Obligations of Borrower to be due and payable and
      proceed to enforce payment of the Obligations and to exercise any and all
      of the rights and remedies afforded to Bank by the Uniform Commercial Code
      or under the terms of this Agreement or otherwise. In addition, upon the
      occurrence and during the continuance of an Event of Default, if Bank
      proceeds to enforce payment of the Obligations, Borrower shall be
      obligated to deliver to Bank cash collateral in an amount equal to the
      aggregate amounts then undrawn on all outstanding Letters of Credit or
      acceptances issued or guaranteed by Bank for the account of Borrower, and
      Bank may proceed to enforce payment of the same and to exercise all rights
      and remedies afforded to Bank by the Uniform Commercial Code or under the
      terms of this Agreement or otherwise. Upon the occurrence of, and during
      the continuance of, an Event of Default, the Borrower, as additional
      compensation to the Bank for its increased credit risk, promises to pay
      interest on all Obligations (including, without limitation, principal,
      whether or not past due, past due interest and any other amounts past due
      under this Agreement) at a per annum rate of five (5%) percent greater
      than the rate of interest then specified in Section 7 of this Agreement.

                                      -38-
<PAGE>

            (b) Upon the filing of any complaint, application, or petition by or
against the Borrower initiating any matter in which the Borrower is or may be
granted any relief from the debts of the Borrower pursuant to the Bankruptcy
Code, Bank's obligation hereunder shall be canceled immediately, automatically,
and without notice, and all Obligations of the Borrower then outstanding shall
become immediately due and payable without presentation, demand, or notice of
any kind to the Borrower, provided, however, it shall not be an Event of Default
hereunder if any such complaint is filed against the Borrower which is being
diligently contested by Borrower until the earlier of (i) the entry of an order
for relief, or (ii) sixty (60) days without the dismissal of such complaint.

            (c) Any sale or other disposition of the Collateral may be at public
or private sale upon such terms and in such manner as the Bank deems advisable,
having due regard to compliance with any statute or regulation which might
affect, limit or apply to the Bank's disposition of the Collateral. The Bank may
conduct any such sale or other disposition of the Collateral upon the Borrower's
premises. Unless the Collateral is perishable or threatens to decline speedily
in value, or is of a type customarily sold on a recognized market (in which
event the Bank shall provide the Borrower with such notice as may be practicable
under the circumstances), the Bank shall give the Borrower at least the greater
of the minimum notice required by law or ten (10) days prior written notice of
the date, time and place of any proposed public sale, and of the date after
which any private sale or other disposition of the Collateral may be made. The
Bank may purchase the Collateral, or any portion of it at any public sale.

            (d) If the Bank sells any of the Collateral on credit, the Borrower
will be credited only with payments actually made by the purchaser of such
Collateral and received by the Bank. If the purchaser fails to pay for the
Collateral, the Bank may re-sell the Collateral and the Borrower shall be
credited with the proceeds of the sale.

            (e) In connection with the Bank's exercise of the Bank's rights
after the occurrence and during the continuance of an Event of Default, the
Bank, in accordance with applicable law, peaceably may enter upon, occupy and
use any premises owned or occupied by the Borrower, and may exclude the Borrower
from such premises or portion thereof as may have been so entered upon,
occupied, or used by the Bank. The Bank shall not be required to remove any of
the Collateral from any such premises upon the Bank's taking possession thereof,
and may render any Collateral unusable to the Borrower. In no event shall the
Bank be liable to the Borrower for use or occupancy by the Bank of any premises
pursuant to this Agreement.

            (f) Upon the occurrence and during the continuance of any Event of
Default, the Bank may require the Borrower to assemble the Collateral and make
it available to the Bank at the Borrower's sole risk and expense at a place or
places which are reasonably convenient to both the Bank and the Borrower.

      19. STANDARDS FOR EXERCISING REMEDIES. To the extent that applicable law
imposes duties on Bank to exercise remedies in a commercially reasonable manner,
Borrower

                                      -39-
<PAGE>

acknowledges and agrees that it is not commercially unreasonable for Bank (a) to
fail to incur expenses reasonably deemed significant by Bank to prepare
Collateral for disposition or otherwise to complete raw material or work in
process into finished goods or other finished products for disposition, (b) to
fail to obtain third party consents for access to Collateral to be disposed of,
or to obtain or, if not required by other law, to fail to obtain governmental or
third party consents for the collection or disposition of Collateral to be
collected or disposed of, (c) to fail to exercise collection remedies against
account debtors or other persons obligated on Collateral or to remove liens or
encumbrances on or any adverse claims against Collateral, (d) to exercise
collection remedies against account debtors and other persons obligated on
Collateral directly or through the use of collection agencies and other
collection specialists, (e) to advertise dispositions of Collateral through
publications or media of general circulation, whether or not the Collateral is
of a specialized nature, (f) to contact other persons, whether or not in the
same business as Borrower, for expressions of interest in acquiring all or any
portion of the Collateral, (g) to hire one or more professional auctioneers to
assist in the disposition of Collateral, whether or not the Collateral is of a
specialized nature, (h) to dispose of the Collateral by utilizing Internet sites
that provide for the auction of assets of the types included in the Collateral
or that have the reasonable capability of doing so, or that match buyers and
sellers of assets, (i) to dispose of assets in wholesale rather than retail
markets, (j) to disclaim disposition warranties specifically to disclaim any
warranties of title or the like, (k) to purchase insurance or credit
enhancements to insure Bank against risks of loss, collection or disposition of
Collateral or to provide to Bank a guaranteed return from the collection or
disposition of Collateral, or (l) to the extent deemed appropriate by Bank, to
obtain the services of other brokers, investment bankers, consultants and other
professionals to assist Bank in the collection or disposition of any of the
Collateral Borrower acknowledges that the purpose of this section is to provide
non-exhaustive indications of what actions or omissions by Bank would not be
commercially unreasonable in Bank's exercise of remedies against the Collateral
and that other actions or omissions by Bank shall not be deemed commercially
unreasonable solely on account of not being indicated in this section. Without
limitation upon the foregoing, nothing contained in this section shall be
construed to grant any rights to Borrower or to impose any duties on Bank that
would not have been granted or imposed by this Agreement or by applicable law in
the absence of this section.

      20. PROCESSING AND SALES OF INVENTORY. So long as Borrower is not in
default hereunder, Borrower shall have the right, in the regular course of
business, to process and sell Borrower's Inventory, and, except for any
interests in the proceeds thereof, such sale shall be free and clear of the
security interest granted to the Bank hereunder. A sale in the ordinary course
of business shall not include a transfer in total or partial satisfaction of a
debt.

      21. WAIVER OF JURY TRIAL. BORROWER AND BANK EACH HEREBY KNOWINGLY,
VOLUNTARILY AND INTENTIONALLY WAIVES ANY RIGHT IT MAY HAVE OR HEREAFTER HAVE TO
A TRIAL BY JURY IN RESPECT OF ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR
RELATING TO THIS AGREEMENT. Borrower hereby certifies that neither Bank nor any
of its representatives, agents or counsel has represented, expressly or
otherwise, that Bank would not, in the event of any such suit, action or
proceeding, seek to enforce this waiver of right to trial by jury. Borrower
acknowledges that Bank has been induced to

                                      -40-

<PAGE>

enter into this Agreement by, among other things, this waiver. Borrower
acknowledges that it has read the provisions of this Agreement and in
particular, this section, has consulted legal counsel, understands the right it
is granting in this Agreement and is waiving in this section in particular, and
makes the above waiver knowingly, voluntarily and intentionally.

      22. CONSENT TO JURISDICTION. Borrower and Bank agree that any action or
proceeding to enforce or arising out of this Agreement may be commenced in any
court of the Commonwealth of Massachusetts sitting in the counties of Suffolk or
Middlesex, or in the District Court of the United States for the District of
Massachusetts, and Borrower waives personal service of process and agrees that a
summons and complaint commencing an action or proceeding in any such court shall
be properly served and confer personal jurisdiction if served by registered or
certified mail to Borrower, or as otherwise provided by the laws of the
Commonwealth of Massachusetts or the United States of America.

      23. TERMINATION.

            (a) Unless renewed in writing, this Agreement solely as it relates
to the Line of Credit shall terminate on May 26, 2007 (the "TERMINATION DATE"),
and all Obligations as they relate to the Line of Credit shall be due and
payable in full without presentation, demand, or further notice of any kind,
whether or not all or any part of the Obligations is otherwise due and payable
pursuant to the agreement or instrument evidencing same. Bank may terminate this
Agreement immediately and without notice upon the occurrence and during the
continuance of an Event of Default. Notwithstanding the foregoing or anything in
this Agreement or elsewhere to the contrary, the security interest, Bank's
rights and remedies hereunder and Borrower's obligations and liabilities
hereunder shall survive any termination of this Agreement and shall remain in
full force and effect until all of the Obligations outstanding, or contracted or
committed for (whether or not outstanding), shall be finally and irrevocably
paid in full, and shall thereupon terminate. No Collateral shall be released or
financing statement terminated until such final and irrevocable payment in full
of the Obligations, as described in the preceding sentence, whereupon all
Collateral shall be released and the Bank shall take all action reasonably
requested by the Borrower to terminate or authorize the termination of all
financing statements and comparable documents.

            (b) In the event that Bank continues to make loans under the Line of
Credit after the Termination Date without a written extension of such
Termination Date or after the occurrence of and during the continuance of an
Event of Default, all such loans (i) shall be made in the sole and absolute
discretion of Bank, and (ii) shall, together with all other Obligations, be
payable thereafter ON DEMAND.

      24. ARBITRATION.

            (a) Except to the extent expressly provided below, any Dispute (as
defined below) shall, upon the request of either party, be determined by binding
arbitration in accordance with the Federal Arbitration Act, Title 9, United
States Code (or if not applicable, the applicable state law),

                                      -41-

<PAGE>

the applicable rules for arbitration of disputes of the Judicial and Mediation
Service ("JAMS") and the "Special Rules" set forth below "Dispute" means any
controversy, claim or dispute between or among the parties to this Loan
Agreement, including any controversy, claim or dispute arising out of or
relating to (a) this Loan Agreement, (b) any other Loan Documents, (c) any
related agreements or instruments, or (d) the transaction contemplated herein or
therein (including any claim based on or arising from an alleged personal injury
or business tort). In the event of any inconsistency, the Special Rules shall
control. The filing of a court action is not intended to constitute a waiver of
the right of Borrower, Guarantor or Bank, including the suing party, thereafter
to require submittal of the Dispute to arbitration. Any party to this Loan
Agreement may bring an action, including a summary or expedited proceeding, to
compel arbitration of any Dispute in any court having jurisdiction over such
action. For the purposes of this dispute resolution provision only, the terms
"party" and "parties" shall include any parent corporation, subsidiary or
affiliate of Bank involved in the servicing, management or administration of any
obligation described in or evidenced by this Loan Agreement, together with the
officers, employees, successors and assigns of each of the foregoing.

            (b) (i) The arbitration shall be conducted in Boston, Massachusetts.

                (ii) The arbitration shall be administered by JAMS, who will
                appoint an arbitrator, if JAMS is unable or legally precluded
                from administering the arbitration, then the American
                Arbitration Association will serve. All Disputes shall be
                determined by one arbitrator, however, if the amount in
                controversy in a Dispute exceeds Five Million Dollars
                ($5,000,000), upon the request of any party, the Dispute shall
                be decided by three arbitrators (for purposes of this Loan
                Agreement, referred to collectively as the "arbitrator").

                (iii) All arbitration hearings will be commenced within ninety
                (90) days of the demand for arbitration and completed within
                ninety (90) days from the date of commencement, provided,
                however, that upon a showing of good cause, the arbitrator shall
                be permitted to extend the commencement of such hearing for up
                to an additional sixty (60) days.

                (iv) The judgment and the award, if any, of the arbitrator shall
                be issued within thirty (30) days of the close of the hearing.
                The arbitrator shall provide a concise written statement setting
                forth the reasons for the judgment and for the award, if any.
                The arbitration award, if any, may be submitted to any court
                having jurisdiction to be confirmed and enforced, and such
                confirmation and enforcement shall not be subject to
                arbitration.

                (v) The arbitrator will have the authority to decide whether any
                Dispute is barred by the statute of limitations and, if so, to
                dismiss the arbitration on that basis. For purposes of the
                application of the statute of limitations, the service on JAMS
                under applicable JAMS rules of a notice of Disputes is the
                equivalent of the filing of a lawsuit.

                (vi) Any dispute concerning this arbitration provision,
                including any such dispute as to the validity or enforceability
                of this provision, or whether a

                                      -42-

<PAGE>

                Dispute is arbitrable, shall be determined by the arbitrator.

                (vii) The arbitrator shall have the power to award legal fees
                and costs pursuant to the terms of this Loan Agreement.

      (c) Nothing in this Loan Agreement shall be deemed to (i) limit the
applicability of any otherwise applicable statutes of limitation and any waivers
contained in this Loan Agreement, or (ii) apply to or limit the right of Bank
(A) to exercise self help remedies such as (but not limited to) setoff, or (B)
to foreclose judicially or nonjudicially against any real or personal property
collateral, or to exercise judicial or nonjudicial power of sale rights, (C) to
obtain from a court provisional or ancillary remedies such as (but not limited
to) injunctive relief, writ of possession, prejudgment attachment, or the
appointment of a receiver, or (D) to pursue rights against a party to this Loan
Agreement in a third-party proceeding in any action brought against Bank in a
state, federal or international court, tribunal or hearing body (including
actions in specialty courts, such as bankruptcy and patent courts). Bank may
exercise the rights set forth in clauses (A) through (D), inclusive, before,
during or after the pendency of any arbitration proceeding brought pursuant to
this Loan Agreement. Neither the exercise of self help remedies nor the
institution or maintenance of an action for foreclosure or provisional or
ancillary remedies shall constitute a waiver of the right of any party,
including the claimant in any such action, to arbitrate the merits of the
Dispute occasioning resort to such remedies. No provision in the Loan Documents
regarding submission to jurisdiction and/or venue in any court is intended or
shall be construed to be in derogation of the provisions in any Loan Document
for arbitration of any Dispute.

      (d) If there is any conflict between the terms, conditions and provisions
of this Section and those of any other provision or agreement for arbitration or
dispute resolution, the terms, conditions and provisions of this Section shall
prevail as to any Dispute arising out of or relating to (i) this Loan Agreement,
(ii) any other Loan Document, (iii) any related agreements or instruments, or
(iv) the transaction contemplated herein or therein (including any claim based
on or arising from an alleged personal injury or business tort). In any other
situation, if the resolution of a given Dispute is specifically governed by
another provision or agreement for arbitration or dispute resolution, the other
provision or agreement shall prevail with respect to said Dispute.

      (e) By agreeing to this Section, the parties irrevocably and voluntarily
waive any right they may have to a trial by jury in respect of any Dispute.

      25. MISCELLANEOUS.

            (a) No delay or omission on the part of Bank in exercising any
rights shall operate as a waiver of such right or any other right. Waiver on any
one occasion shall not be construed as a bar to or waiver of any right or remedy
on any future occasion. All Bank's rights and remedies, whether evidenced hereby
or by any other agreement, instrument or paper, shall be cumulative and may be
exercised singularly or concurrently.

            (b) Bank is authorized to make loans under the terms of this
Agreement upon the

                                      -43-

<PAGE>

request, either written or oral, in the name of Borrower or any authorized
person whose name appears at the end of this Agreement or of any of the
following named person, or persons from time to time, holding the following
offices of Borrower, President, Treasurer and such other officers and authorized
signatories as may from time to time be set forth in separate resolutions. Any
request for a loan which is not accompanied by a Notice of Borrowing shall be
deemed a request for a Prime Rate Loan.

            (c) This Agreement shall bind and inure to the benefit of the
respective successors and assigns of each of the parties hereto, provided,
however, that Borrower may not assign this Agreement or any rights or duties
hereunder without Bank's prior written consent and any prohibited assignment
shall be absolutely void. No consent to an assignment by Bank shall release
Borrower from its Obligations. Bank may assign this Agreement and its rights and
duties hereunder and no consent or approval by Borrower is required in
connection with any such assignment. Bank reserves the right to sell, assign,
transfer, negotiate or grant participations in all or any part of, or any
interest in Bank's rights and benefits hereunder. In connection with any
assignment or participation, Bank may disclose all documents and information
which Bank now or hereafter may have relating to Borrower or Borrower's
business. To the extent that Bank assigns its rights and obligations hereunder
to another party, Bank thereafter shall be released from such assigned
obligations to Borrower and such assignment shall effect a novation between
Borrower and such other party.

            (d) Borrower agrees that any and all loans made by Bank to Borrower
or for its account under this Agreement shall be conclusively deemed to have
been authorized by Borrower and to have been made pursuant to duly authorized
requests therefor on its behalf.

            (e) Unless otherwise defined in this Agreement, capitalized words
shall have the meanings set forth in the Uniform Commercial Code as in effect in
the Commonwealth of Massachusetts as of the date of this Agreement.

            (f) Paragraph and section headings used in this Agreement are for
convenience only, and shall not effect the construction of this Agreement. If
one or more provisions of this Agreement (or the application thereof) shall be
invalid, illegal or unenforceable in any respect in any jurisdiction, the same
shall not, invalidate or render illegal or unenforceable such provision (or its
application) in any other jurisdiction or any other provision of this Agreement
(or its application). This Agreement is the entire agreement of the parties with
respect to the subject matter hereof and supersedes any prior written or verbal
communications or instruments relating thereto.

            (g) Unless otherwise provided in this Agreement, all notices or
demands by any party relating to this Agreement or any other loan document shall
be in writing and (except for financial statements and other informational
documents which may be sent by first-class mail, postage prepaid) shall be
personally delivered or sent by registered or certified mail (postage prepaid,
return receipt requested), overnight courier, or telefacsimile to Borrower or to
Bank, as the case may be, at its address set forth below.

      For value received, the undersigned, iRobot Corporation, a Delaware
corporation (the "BORROWER"), hereby promises to pay on May 26, 2007 to the
order of Fleet National Bank, a Bank of America company (the "BANK"), at its
main office in Boston, Massachusetts, or at any other place designated at any
time by the holder hereof, in lawful money of the United States of America and
in immediately available funds, the principal sum of Twenty Million
($20,000,000.00) Dollars, or, if less, the aggregate unpaid principal amount of
all loans made by the Bank to the Borrower under the Loan Agreement (defined
below) together with interest on the principal amount hereunder remaining unpaid
from time to time, computed on the basis of the actual number of days elapsed
and a 360-day year, from the date hereof until this Note is fully paid at the
rate(s) from time to time in effect under the Loan and Security Agreement of
even date herewith (the "Loan Agreement") by and between the Bank and the
Borrower. The principal hereof and interest accruing thereon shall be due and
payable as provided in the Loan Agreement. This Note may be prepaid only in
accordance with the Loan Agreement.

      This Note is issued pursuant, and is subject, to the Loan Agreement, which
provides, among other things, for acceleration hereof. This Note is the "Note"
referred to in the Loan Agreement.

      Bank shall have the option of imposing, and Borrower shall pay upon
billing therefor, an interest rate which is five (5%) percent per annum above
the interest rate otherwise payable ("Default Rate") (a) during any Event of
Default, unless and until the Event of Default is waived by Bank and (b) after
the Termination Date.

      Borrower shall pay, upon billing therefor, a "Late Charge" equal to five
(5%) percent of the amount of any payment of principal, other than principal due
at the Termination Date, interest, or both, which is not paid when due. Late
charges are (a) payable in addition to, and not in limitation of, the Default
Rate, (b) intended to compensate Bank for administrative and processing costs
incident to late payments, (c) are not interest, and (d) shall not be subject to
refund or rebate or credited against any other amount due.

      This Note is secured, among other things, pursuant to the Loan Agreement,
and may now or hereafter be secured by one or more other security agreements,
mortgages, deeds of trust, assignments or other instruments or agreements.

      The Borrower hereby agrees to pay all costs of collection, including
reasonable attorneys' fees and legal expenses in the event this Note is not paid
when due, whether or not legal proceedings are commenced.

<PAGE>

      Presentment or other demand for payment, notice of dishonor and protest
are expressly waived.

      Bank may at any time pledge or assign 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 Bank from its obligations under any of the Loan Documents.

      Upon receipt of an affidavit and indemnity of an officer of Bank as to the
loss, theft, destruction or mutilation of the Note or any other security
document which is not of public record, and, in the case of such loss, theft,
destruction or mutilation, upon cancellation of such Note or other security
document, Borrower will issue, in lieu thereof, a replacement note or other
security document in the same principal amount thereof and otherwise of like
tenor.

      This Note is intended by the parties as the final, complete and exclusive
statement of the transactions evidenced by this Note. All prior or
contemporaneous promises, agreements and understandings, whether oral or
written, are deemed to be superceded by this Note and no party is relaying on
any promise, agreement or understanding not set forth in this Note. This Note

$2,000,000.00                                              Boston, Massachusetts
                                                                    May 26, 2005

1.    Promise To Pay.

      FOR VALUE RECEIVED, iRobot Corporation, a Delaware corporation having an
address at 63 South Avenue, Burlington, Massachusetts 01803 ("Borrower")
promises to pay to the order of FLEET NATIONAL BANK, a Bank of America company,
a national banking association, having an address at 100 Federal Street, Boston,
Massachusetts 02110 ("Lender"), the principal sum of TWO MILLION ($2,000,000.00)
DOLLARS, with interest thereon, or on the amount thereof from time to time
outstanding, to be computed, as hereinafter provided, on each advance from the
date of its disbursement until such principal sum shall be fully paid. Interest
shall be payable in installments as set forth in Section 4 below. The total
principal sum, or the amount thereof outstanding, together with any accrued but
unpaid interest, shall be due and payable in full on May 26, 2012 ("Maturity
Date"), which term is further defined in, and is subject to acceleration in
accordance with, the Loan and Security Agreement (the "Loan Agreement") between
Borrower and Lender dated as of even date as may be amended from time to time.
Any amounts repaid by the Borrower may not be reborrowed.

2.    Loan Agreement.

      This Note is issued pursuant to the terms, provisions and conditions of
the Loan Agreement and evidences the Equipment Term Loan made pursuant thereto.
Capitalized terms used herein which are not otherwise specifically defined shall
have the same meaning herein as in the Loan Agreement.

3.    Interest Rates.

      3.1. Borrower's Options. Principal amounts outstanding under this Note
      shall bear interest at the following rates, at Borrower's selection,
      subject to the conditions and limitations provided for in this Note (i)
      Prime Rate or (ii) LIBOR Based Rate.

      3.1.1. Selection To Be Made. Borrower shall select, and thereafter may
      change the selection of, the applicable interest rate, from the
      alternatives otherwise provided for in this Note, by giving Lender a
      Notice of Rate Selection (i) prior to the initial Loan Advance, (ii) prior
      to the end of each Interest Period applicable to a LIBOR Rate Loan or (iii
      ) on any Business Day on which Borrower desires to convert an outstanding
      Prime Rate Loan to a LIBOR Rate Loan, provided, however, if an Event of
      Default exists, Borrower's right to select interest rate options other
      than ones based upon the Prime Rate shall cease.

      3.1.2. Notice. A "Notice of Rate Selection" shall be a written notice,
      given by cable, tested telex, telecopier (with authorized signature), or
      by telephone if immediately confirmed by such a written notice, from an
      authorized representative of Borrower which (i) is irrevocable, (ii) is
      received by Lender not later than 10:00 o'clock A.M. Boston time (a) if a
      LIBOR Based Rate is selected, at least three (3) Business Days prior to
      the first day of the Interest Period to which such selection is to apply,
      or (b) if a Prime Rate Loan is selected, on

<PAGE>

      option, sets forth the aggregate principal amount(s) to which such
      interest rate option(s) shall apply and the Interest Period(s) applicable
      to each LIBOR Rate Loan.

      3.1.3. If No Notice. If Borrower fails to select an interest rate option
      in accordance with the foregoing prior to the closing date hereof, or
      prior to the last day of the applicable Interest Period of an outstanding
      LIBOR Rate Loan, or if a LIBOR Rate Loan is not available, any loan made
      shall be deemed to be a Prime Rate Loan, and on the last day of the
      applicable Interest Period all outstanding principal amounts shall be
      deemed converted to a Prime Rate Loan.

      3.3. Telephonic Notice. Without any way limiting Borrower's obligation to
      confirm in writing any telephonic notice, Lender may act without liability
      upon the basis of telephonic notice reasonably believed by Lender to be
      from Borrower prior to receipt of written confirmation. In each case
      Borrower hereby waives the right to dispute Lender's record of the terms
      of such telephonic Notice of Rate Selection in the absence of manifest
      error.

      3.4. Limits On Options, One Selection Per Month. Each LIBOR Rate Loan
      shall be in a minimum amount of $250,000.00. At no time shall there be
      outstanding a total of more than five (5) LIBOR Rate Loans combined at any
      time. If Borrower shall make more than one (1) interest rate selection in
      any thirty (30) day period, excluding conversions of outstanding advances
      made at the end of an applicable Interest Period of any previously
      outstanding LIBOR Rate Loan, Lender may impose and Borrower shall pay a
      reasonable processing fee for each such additional selection.

4.    Payment of Interest and Principal.

      4.1. Payment and Calculation of Interest. All interest on Prime Rate Loans
      shall be (a) payable in arrears on the first day of each month commencing
      on June 1, 2005 and on the same day of each month thereafter until the
      principal together with all interest and other charges payable with
      respect to the Loan shall be fully paid, and (b) calculated on the basis
      of a 360 day year and the actual number of days elapsed. Each change in
      the Prime Rate shall simultaneously change the Prime Rate payable under
      this Note. Interest at the LIBOR Based Rate shall be computed from and
      including the first day of the applicable Interest Period to, but
      excluding, the last day thereof and shall be payable in arrears for any
      LIBOR Based Rate having an Interest Period of three months or less, the
      last Business Day of such Interest Period, and as to any LIBOR Based Rate
      having an Interest Period longer than three months, each Business Day
      which is three months, or a whole multiple thereof, after the first day of
      such Interest Period and the last day of such Interest Period.

      4.2. Principal. Principal shall be payable on the first day of each month
      commencing on June 1, 2007 and on the same day of each month thereafter in
      59 monthly consecutive principal installments of each equal to the
      Principal Repayment Amount with the entire outstanding principal balance
      and all other interest, expenses and charges due and payable in full upon
      Maturity.

      4.3. Prepayment. The Loan or any portion thereof may be prepaid in full or
      in part at any time upon one (1) day's prior written notice to the holder
      of this Note without premium or penalty with respect to Prime Rate Loans
      and, with respect to LIBOR Rate Loans subject to applicable provisions of
      Sections 4.10 and 4.11 hereof. Any partial prepayment of principal shall
      first be applied to any installment of principal then due and then be
      applied to the

<PAGE>

      principal due in the reverse order of maturity, and no such partial
      prepayment shall relieve Borrower of the obligation to pay each subsequent
      installment of principal when due.

      4.4 Maturity. At Maturity all accrued interest, principal and other
      charges due with respect to the Loan shall be due and payable in full and
      the principal balance and such other charges, but not unpaid interest,
      shall continue to bear interest at the Default Rate until so paid.

      4.5 Method of Payment, Date of Credit. All payments of interest, principal
      and fees shall be made in immediately available funds, without
      counterclaim or set off and free and clear of, and without any deduction
      or withholding for, any taxes or other payments (a) by direct charge to an
      account of Borrower maintained with Lender (or the then holder of the
      Loan), or (b) by wire transfer to Lender or (c) by check payable to Lender
      and delivered to Lender at 100 Federal Street, Boston, Massachusetts, or
      (d) to such other bank or address as the holder of the Loan may designate
      in a written notice to Borrower. Payments shall be credited on the
      Business Day on which immediately available funds are received prior to
      one o'clock P.M. Eastern Time, payments received after one o'clock P.M.
      Eastern Time shall be credited to the Loan on the next Business Day.
      Payments which are by check, which Lender may at its option accept or
      reject, or which are not in the form of immediately available funds shall
      not be credited to the Loan until such funds become immediately available
      to Lender, and, with respect to payments by check, such credit shall be
      provisional until the item is finally paid by the payor bank.

      4.6 Billings. Lender may submit billings reflecting payments due, however,
      any changes in the interest rate which occur between the date of billing
      and the due date may be reflected in the billing for a subsequent month.
      Neither the failure of Lender to submit a billing nor any error in any
      such billing shall excuse Borrower from the obligation to make full
      payment of all Borrower's payment obligations when due but Borrower shall
      not be in default if Borrower pays in full the amount billed in good
      faith.

      4.7 Application of Payments. All payments shall be applied first to the
      payment of all fees, expenses and other amounts due to the Lender (other
      than principal and interest), then to accrued interest, and thereafter to
      outstanding principal, provided, however, after the occurrence of any
      Default which is continuing or any Event of Default, payments will be
      applied to the Obligations of Borrower in such order and manner as Lender
      determines in its sole discretion.

      4.8 Default Rate. Lender shall have the option of imposing, and Borrower
      shall pay upon billing therefor, an interest rate which is five percent
      (5%) per annum above the interest rate otherwise payable ("Default Rate")
      (a) following any Event of Default, unless and until the Event of Default
      is waived by Lender, and (b) after Maturity.

      4.9 Late Charges. Borrower shall pay, upon billing therefor, a "Late
      Charge" equal to five percent (5%) of the amount of any payment of
      principal, other than principal due at Maturity, interest, or both, which
      is not paid when the due date thereof. Late charges are (a) payable in
      addition to, and not in limitation of, the Default Rate, (b) intended to
      compensate Lender for administrative and processing costs incident to late
      payments, (c) are not interest, and (d) shall not be subject to refund or
      rebate or credited against any other amount due.

<PAGE>

      4.10 Calculation of Yield Maintenance.

            (i) Borrower may prepay a LIBOR Rate Loan only upon at least three
      (3) Business Days prior written notice to Lender (which notice shall be
      irrevocable), and any such prepayment shall occur only on the last day of
      the Interest Period for such LIBOR Rate Loan. Borrower shall pay to
      Lender, upon request of Lender, such amount or amounts as shall be
      sufficient (in the reasonable opinion of Lender) to compensate it for any
      loss, cost or expense incurred as a result of (i) any payment of a LIBOR
      Rate Loan on a date other than the last day of the Interest Period for
      such Loan, (ii) any failure by Borrower to borrow a LIBOR Rate Loan on the
      date specified by Borrower's written notice, (iii) any failure by Borrower
      to pay a LIBOR Rate Loan on the date for payment specified in Borrower's
      written notice Without limiting the foregoing, Borrower shall pay to
      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 chosen pursuant to the LIBOR Rate Election as to which
      the prepayment is made, shall be subtracted from the LIBOR Based 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 chosen pursuant to the LIBOR Rate Election as to which the prepayment
      is made. Said amount shall be reduced to present value calculated by using
      the above referenced term chosen pursuant to the LIBOR Rate Election as to
      which prepayment is made. The resulting amount shall be the yield
      maintenance fee due to Lender upon the prepayment of a LIBOR Rate Loan.
      Each reference in this paragraph to "LIBOR Rate Election" shall mean the
      election by Borrower of the LIBOR Based Rate. If by reason of an Event of
      Default, Lender elects to declare the note to be immediately due and
      payable, then any yield maintenance fee with respect to a LIBOR Rate Loan
      shall become due and payable in the same manner as though Borrower had
      exercised such right of prepayment.

            (ii) The foregoing yield maintenance fees shall be payable in
      respect of all prepayments of principal whether voluntary or involuntary
      including, without limitation, prepayments made upon acceleration of the
      Loan, or application of insurance or eminent domain proceeds.

            (iii) Once written notice of intention to prepay is given, the Loan,
      or the applicable portion thereof, shall become due and payable in full on
      the date specified in the notice of prepayment and the failure to so
      prepay the loan on such date, together with any applicable yield
      maintenance fees, shall constitute an Event of Default.

            (iv) If during an Event of Default Lender elects to declare the Loan
      to be immediately due and payable, then any yield maintenance fee with
      respect to the Loan shall become due and payable in the same manner as
      though Borrower had exercised such right of prepayment.

      4.11 Make Whole Provision. Without duplication of any yield maintenance
      fee payable under Section 4.10, Borrower shall pay to Lender, immediately
      upon request and notwithstanding contrary provisions contained in any of
      the Loan Documents, such amounts as shall, in the conclusive judgment of
      Lender (in the absence of manifest error), compensate Lender for the loss,
      cost or expense which it may reasonably incur as a result of

      (i) any payment or prepayment, under any circumstances whatsoever, whether
      voluntary or involuntary, of all or any portion of a LIBOR Rate Loan on a
      date other than the last day of the applicable Interest Period of a LIBOR
      Rate Loan, or (ii) the conversion, for any reason whatsoever, whether
      voluntary or involuntary, of any LIBOR Rate Loan to a Prime Rate Loan on a
      date other than the last day of the applicable Interest Period. Such
      amounts payable by Borrower shall be equal to any administrative costs
      actually incurred plus any amounts required to compensate for any loss,
      cost or expense incurred by reason of the liquidation or re-employment of
      deposits or other funds acquired by Lender to fund or maintain a LIBOR
      Rate Loan.

      occurrence thereof and Borrower from time to time shall, upon written
      demand by Lender, pay Lender additional amounts sufficient to indemnify
      Lender against the increased cost. A certificate as to the amount of the

      the absence of manifest error, shall be conclusive and binding for all
      purposes.

      6.2 Illegality. Notwithstanding any other provision of this Note, if the
      introduction of or change in or in the interpretation of any law, treaty,
      statute, regulation or interpretation thereof shall make it unlawful, or

      guideline or otherwise, that it is unlawful, for Lender to make or
      maintain LIBOR Rate Loans or to continue to fund or maintain LIBOR Rate
      Loans then, on written notice thereof and demand by Lender to Borrower,
      (a) the obligation of Lender to make LIBOR Rate Loans and to convert or
      continue any Loan Advances as LIBOR Rate Loans shall terminate and (b)
      Borrower shall convert all principal outstanding under this Note into
      Prime Rate Loans.

      Based Rate and the maintenance of Loan Advances at such rate shall be
      subject to the following additional terms and conditions:

            (i) Availability. If, before or after Borrower has selected to take
      or maintain a LIBOR Rate Loan Lender notifies Borrower that

                  (a) dollar deposits in the amount and for the maturity
      requested are not available to Lender in the London interbank market at
      the rate specified in the definition of LIBOR Rate set forth above, or

<PAGE>

                  (b) reasonable means do not exist for Lender to determine the
      LIBOR Rate for the amounts and maturity requested, then the principal
      which would have been a LIBOR Rate Loan shall be a Prime Rate Loan.

            (ii) Payments Net of Taxes. All payments and prepayments of
      principal and interest under this Note shall be made net of any taxes and
      costs resulting from having principal outstanding at or computed with
      reference to a LIBOR Based Rate. Without limiting the generality of the
      preceding obligation, illustrations of such taxes and costs are taxes, or
      the withholding of amounts for taxes, of any nature whatsoever including
      income, excise, interest equalization taxes (other than United States or
      state income taxes) as well as all levies, imposts, duties or fees whether
      now in existence or as the result of a change in or promulgation of any
      treaty, statute, regulation, or interpretation thereof or any directive
      guideline or otherwise by a central bank or fiscal authority (whether or
      not having the force of law) or a change in the basis of, or the time of
      payment of, such taxes and other amounts resulting therefrom.

      6.4. Prime Rate Loans. Each Prime Rate Loan shall continue as a Prime Rate
      Loan until Maturity of the Loan, unless sooner converted, in whole or in
      part, to a LIBOR Rate Loan, subject to the limitations and conditions set
      forth in this Note.

      6.5. Conversion of Other Advances. At the end of each applicable Interest
      Period, the applicable LIBOR Rate Loan shall be converted to a Prime Rate
      Loan unless Borrower selects another option in accordance with the
      provisions of this Note.

7.    Acceleration, Event of Default.

      Upon the occurrence and during the continuance of any one or more of the
Events of Default, any and all liabilities of the Borrower to the Lender shall
become immediately due and payable, at the option of the Lender and without
notice or demand. The occurrence of any Event of Default shall also constitute,
without notice or demand, a default under all other agreements between the
Lender, and the Borrower and instruments and papers given the Lender by the
Borrower, whether such agreements, instruments, or papers now exist or hereafter
arise.

8.    Certain Waivers, Consents and Agreements.

      Each and every party liable hereon or for the indebtedness evidenced
hereby whether as maker, endorser, guarantor, surety or otherwise hereby (a)
waives presentment, demand, protest, suretyship defenses and defenses in the
nature thereof, (b) waives any defenses based upon and specifically assents to
any and all extensions and postponements of the time for payment, changes in
terms and conditions and all other indulgences and forbearances which may be
granted by the holder to any party now or hereafter liable hereunder or for the
indebtedness evidenced hereby, (c) agrees to any substitution, exchange,
release, surrender or other delivery of any security or collateral now or
hereafter held hereunder or any of the other Loan Documents, and to the addition
or release of any other party or person primarily or secondarily liable, (d)
agrees that if any security or collateral given to secure this Note or the
indebtedness evidenced hereby or to secure any of the obligations set forth or
referred to in any of the Loan Documents, shall be found to be unenforceable in
full or to any extent, or if Lender or any other party shall fail to duly
perfect or protect such collateral, the same shall not relieve or release any
party liable hereon or thereon nor vitiate any other security or collateral
given for any obligations evidenced hereby or thereby, (e) agrees to pay all
costs and expenses reasonably incurred by Lender or any
<PAGE>

other holder of this Note in connection with the indebtedness evidenced hereby,
including, without limitation, all attorneys' fees and costs, for the
implementation of the Loan, the collection of the indebtedness evidenced hereby
and the enforcement of rights and remedies hereunder or under the other Loan
Documents, whether or not suit is instituted, and (f) consents to all of the
terms and conditions contained in this Note, and all other instruments now or
hereafter executed evidencing or governing all or any portion of the security or
collateral for this Note or any one or more of the Loan Documents.

9.     Delay Not A Bar.

      No delay or omission on the part of the holder in exercising any right
hereunder or any right under any instrument or agreement now or hereafter
executed in connection herewith, or any agreement or instrument which is given
or may be given to secure the indebtedness evidenced hereby or any other
agreement now or hereafter executed in connection herewith or therewith shall
operate as a waiver of any such right or of any other right of such holder, nor
shall any delay, omission or waiver on any one occasion be deemed to be a bar to
or waiver of the same or of any other right on any future occasion.

10.    Partial Invalidity.

      The invalidity or unenforceability of any provision hereof, of the Loan
Documents, or of any other instrument, agreement or document now or hereafter
executed in connection with the Loan made pursuant hereto and thereto shall not
impair or vitiate any other provision of any of such instruments, agreements and
documents, all of which provisions shall be enforceable to the fullest extent
now or hereafter permitted by law.

11.    Compliance With Usury Laws.

      All agreements between Borrower, each Guarantor and Lender are hereby
expressly limited so that in no contingency or event whatsoever, whether by
reason of acceleration of maturity of the indebtedness evidenced hereby or
otherwise, shall the amount paid or agreed to be paid to Lender for the use or
the forbearance of the indebtedness evidenced hereby exceed the maximum
permissible under applicable law. As used herein, 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 Note 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
Borrower and Lender in the execution, delivery and acceptance of this Note 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
performance of such provision shall be due, shall involve transcending the limit
of validity prescribed by applicable law, then the obligation to be fulfilled
shall automatically be reduced to the limit of such validity, and if under or
from any circumstances whatsoever 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
evidenced hereby and not to the payment of interest. This provision shall
control every other provision of all agreements between Borrower, the Guarantor
and Lender.

12.    Security.

<PAGE>

      THIS NOTE OR ANY OF THE OTHER LOAN DOCUMENTS MAY BE BROUGHT IN THE COURTS
      OF THE COMMONWEALTH OF MASSACHUSETTS OR ANY FEDERAL COURT SITTING THEREIN
      AND CONSENTS TO THE NONEXCLUSIVE JURISDICTION OF SUCH COURT AND SERVICE OF
      PROCESS IN ANY SUCH SUIT BEING MADE UPON BORROWER BY MAIL AT THE ADDRESS
      SET FORTH IN THE LOAN AGREEMENT. BORROWER HEREBY WAIVES ANY OBJECTION THAT
      IT MAY NOW OR HEREAFTER HAVE TO THE VENUE OF ANY SUCH SUIT OR ANY SUCH
      COURT OR THAT SUCH SUIT IS BROUGHT IN AN INCONVENIENT FORUM.

      INCLUDING, WITHOUT LIMITATION, ANY COURSE OF CONDUCT, COURSE OF DEALINGS,
      STATEMENTS OR ACTIONS OF LENDER RELATING TO THE ADMINISTRATION OF THE LOAN

      OR RECOVER IN ANY LITIGATION ANY SPECIAL, EXEMPLARY, PUNITIVE OR
      CONSEQUENTIAL DAMAGES OR ANY DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL

or assignment or enforcement thereof shall release Lender from its obligations
under any of the Loan Documents.

19.   General Rights of Assignment and Participation. Lender shall have the
unrestricted right at any time or from time to time, and without Borrower's or
any Guarantor's consent, to assign all or any portion of its rights and

execute, or cause to be executed, such documents, including without limitation,
amendments to this Agreement and to any other documents, instruments and
agreements executed in connection herewith as Lender shall deem necessary to
effect the foregoing. In addition, at the request of Lender and any such
Assignee, Borrower shall issue one or more new promissory notes, as applicable,
to any such Assignee and, if Lender has retained any of its rights and
obligations hereunder following such assignment, to Lender, which new promissory
notes shall be issued in replacement of, but not in discharge of, the liability
evidenced by the promissory note held by Lender prior to such assignment and
shall reflect the amount of the respective commitments and loans held by such
Assignee and Lender after giving effect to such assignment. Upon the execution
and delivery of appropriate assignment documentation, amendments and any other
documentation required by Lender in connection with such assignment and the
payment by Assignee of the purchase price agreed to by Lender, and such
Assignee, such Assignee shall be a party to this Agreement and shall have all of
the rights and obligations of Lender hereunder (and under any and all other
guaranties, documents, instruments and agreements executed in connection
herewith) to the extent that such rights and obligations have been assigned by
Lender pursuant to the assignment documentation between Lender and such
Assignee, and Lender shall

<PAGE>

be released from its obligations hereunder and thereunder to a corresponding
extent. Lender may furnish any information concerning Borrower, Guarantor or the
collateral in its possession from time to time to prospective Assignees,
provided that Lender require any such prospective Assignees to agree in writing
to maintain the confidentiality of such information.

      Lender shall have the unrestricted right at any time and from time to
time, and without the consent of or notice to Borrower or any Guarantor, to
grant to one or more banks or other financial institutions (each, a
"Participant") participating interests in Lender's obligation to lend hereunder
and/or any or all of the loans held by Lender hereunder. In the event of any
such grant by Lender of a participating interest to a Participant, whether or
not upon notice to Borrower, Lender shall remain responsible for the performance
of its obligations hereunder and Borrower shall continue to deal solely and
directly with Lender in connection with Lender's rights and obligations
hereunder. Lender may furnish any information concerning Borrower in its
possession from time to time to prospective Participants, provided that Lender
shall require any such prospective Participant to agree in writing to maintain
the confidentiality of such information.

20.   Replacement Note. Upon receipt of an affidavit and indemnity of an officer
of Lender as to the loss, theft, destruction or mutilation of the Note 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 Note or
other security document, Borrower will issue, in lieu thereof, a replacement
note or other security document in the same principal amount thereof and
otherwise of like tenor.

21.   Integration. This Note is intended by the parties as the final, complete
and exclusive statement of the transactions evidenced by this Note. All prior or
contemporaneous promises, agreements and understandings, whether oral or
written, are deemed to be superceded by this Note and no party is relaying on
any promise, agreement or understanding not set forth in this Note. This Note
may not be amended or modified except by a written instrument describing such
amendment or modification executed by Borrower and Lender.

22.   Use of Proceeds. No portion of the proceeds of the Loan shall be used, in
whole or in part, for the purpose of purchasing or carrying any "margin stock"
as such term is defined in Regulation U of the Board of Governors of the Federal
Reserve System.

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