BUSINESS DEVELOPMENT COMPANY OF RHODE ISLAND, a Rhode Island corporation with
its principal place of business at 40 Westminster Street, Suite 702, Providence,
Rhode Island 02903 (the "Lender"), and NETWORK SIX, INC., a Rhode Island
corporation with its principal address at 475 Kilvert Street, Warwick, Rhode

            I. GENERAL TERMS

            Section 1.01. Loan:

            The Borrower agrees to borrow from the Lender the principal sum of
up to Two Hundred Fifty Thousand Dollars ($250,000) on a term basis (the
"Loan"), and the Lender has agreed to make the Loan to the Borrower, subject to
all the terms and conditions of this Agreement.

            Section 1.02. Note:

            The Loan shall be evidenced by the Borrower's $250,000 Term

Note is hereby incorporated herein by reference and made a part hereof.

            Section 1.03. Prepayment.

            Subject to the provisions hereof, the Borrower may prepay the
principal of the Note, in whole at any time, or in part, as long as any
prepayment is equal to at least 5% of any outstanding principal balance from
time to time, and tendered on any principal payment date upon not less than ten
(10) business days prior written notice to the Lender. Each such notice shall
specify the prepayment date and the principal amount of the Note to be prepaid.
If prepayment is made on

the Note at any time between the date hereof and five (5) years from the date
hereof, the prepayment penalty shall be equal to five percent (5%) of the
prepaid amount.

            All prepayments shall be applied to the payment of installments of
principal of the Note in the inverse order of maturity thereof. Each prepayment
shall be accompanied by the interest accrued on the principal amount so prepaid
through the date of prepayment.

            Section 1.04. Use of Proceeds:

            The proceeds of the Loan shall be used to hire additional marketing

Loan proceeds shall not be used for any other purpose including the financing of
legal expenses.

            Section 1.05. Security for the Note:

            The Note and the Borrower's obligations thereunder shall be secured
by:

            (a) a second (behind only a senior lender's lien on accounts
receivable and work-in-process and other senior liens set forth on Exhibit C
hereto) priority security interest (shared on a pari passu basis with the Small
Business Loan Fund Corp. ("SBLFC")) in all of the tangible and intangible
personal property of the Borrower pursuant to the terms of a Security Agreement
of even date (the "Security Agreement");

            (b) reserved.

            All agreements and instruments described in this Section 1.05,
together with any and all other agreements and instruments heretofore or
hereafter securing the Note, are sometimes hereinafter


                                        2
<PAGE>

referred to collectively as the "Security Documents" and individually as a
"Security Document".

            Section 1.06. Loan Commitment Deferred Fee:

            The Borrower, subject to the terms and conditions of this Agreement
and of the Note, shall pay to the Lender a loan commitment deferred fee of
Twenty-Five Thousand Dollars ($25,000) (the "Deferred Fee") in five (5)
consecutive annual payments, each in the sum of Five Thousand Dollars ($5,000),
beginning on the 1st day of September, 1999, and payable on the same day of each
successive year or the next business day thereafter, with a final payment being
due and payable on September 1, 2003; provided, however, that if the Borrower
prepays the principal of the Note in whole at any time, then the Deferred Fee
shall be due and payable immediately upon such prepayment. Further, the Borrower
agrees that the Deferred Fee, if not paid when due, shall bear interest at the
rate provided for in the Note on the entire unpaid balance of the Deferred Fee,
and shall in all events be secured by the lien of the Security Agreement.

            II. REPRESENTATIONS AND WARRANTIES

            The Borrower represents and warrants to the Lender (which
representations and warranties shall survive the delivery of the Note and the
making of the Loan) that:

            Section 2.01. The Borrower has heretofore furnished to the Lender a
balance sheet of the Borrower and profit and loss and surplus statements of the

prepared in accordance with generally accepted principles of accounting ("GAAP")
applied on a basis consistent with that of preceding periods and are complete
and correct and fairly present the financial condition of the Borrower as at
said dates, and the results of its operations for the year or other period ended
on said dates. To the best of the Borrower's knowledge and belief, the Borrower
has no contingent obligations, liabilities for taxes or unusual forward or
long-term commitments except as in the foregoing financial statements
specifically mentioned. Since the date(s) of said financial statements, there
has been no material adverse change in the financial condition of the Borrower,
nor any material decrease in sales or order backlog, and since that date no
dividends or other distributions on common stock have been paid or made to the
stockholders of the Borrower except as may be otherwise stated in a letter of
the Borrower to the Lender dated the date of this Agreement and acknowledged in
writing by the Lender.

now being conducted and is qualified to do business in every jurisdiction where
to Borrower's knowledge such qualification is necessary and (c) has the
corporate power to execute and deliver, and perform its obligations under this
Agreement, the Note and the Security Documents.

            Section 2.03. The execution and delivery and performance by the
Borrower of its obligations under this Agreement, the Note and each of the
Security Documents have been duly authorized by all requisite corporate action
and will not violate any provision of law, any order of any court or other
agency of government, the corporate charter or by-laws of the Borrower or any
indenture, agreement or other instrument to which it is a party, or by which it
is bound, or be in conflict with, result in a breach of, or constitute (with due
notice or lapse of time or both) a default under, or except as may be provided
by this Agreement, result in the creation or imposition of any lien, charge or
encumbrance of any nature whatsoever upon any of the property or assets of the
Borrower pursuant to, any such indenture, agreement or instrument. The Borrower
is not required to obtain any consent, approval or authorization from, or to

performance of this Agreement, the Note or the Security Documents.

            Section 2.04. Except as previously disclosed in writing to Lender,
there is no action, suit or proceeding at law or in equity or by or before any
governmental instrumentality or other agency now pending or, to the knowledge of
the Borrower, threatened against or affecting the Borrower which, if adversely
determined, would have a material adverse effect on the business, operations,
properties, assets or condition, financial or otherwise, of the Borrower.

            Section 2.05. The Borrower is not a party to any agreement or
instrument or subject to any charter or other corporate restriction materially
adversely affecting its business, properties or assets, operations or
conditions, financial or otherwise, other than has been previously disclosed to
the Lender. The Borrower is not in default in the performance, observance or
fulfillment of any of the obligations, covenants or conditions contained in any
agreement or instrument to which it is a party, other than as previously
disclosed in writing to the Lender.

            Section 2.06. The Borrower has good title to all of its properties
and assets, free and clear of all mortgages, security interests, restrictions,
liens and encumbrances of any kind, except liens permitted hereunder and
restrictions, easements and minor irregularities in title which do not and will
not materially interfere with the occupation, use and enjoyment by the Borrower
of such properties and assets in the normal course of its business as presently
conducted or materially impair the value of such properties and assets for the
purpose of such business.

            Section 2.07. Any borrowings made by the Borrower under this
Agreement do not and will not render the Borrower insolvent; the Borrower is not
contemplating either the filing of a petition by it under any state or federal

has not been disclosed to the Lender which materially affects adversely, nor as
far as the Borrower can foresee, will materially affect adversely the property,
business, operations or condition (financial or otherwise) of the Borrower.

            Section 2.09. The Borrower is not an "investment company", or a

            Section 2.11. The Borrower does not have a pension, profit sharing
or other similar plan providing for a program of deferred compensation to any

herewith and acknowledged by the Lender in writing. With respect to such
plan(s), if any, Borrower covenants and agrees to cause to be paid when due all
amounts necessary to fund in accordance with its terms all such plan(s) and will
take no action


                                        7
<PAGE>

            Section 5.01. Incur, create, assume, become or be liable in any
manner with respect to, or permit to exist, any indebtedness or liability,

            In each case of happening of any of the following events (each of
which is herein and in the Note sometimes called an "Event of Default"):

            (a) any representation or warranty made herein, or in any report,

for more than ten (10) days after the date when the same shall become due and

                                       21
<PAGE>

than to the Lender), if the effect of such default is to accelerate the maturity
of such indebtedness or to permit the holder thereof to cause such indebtedness
to become due prior to the stated maturity thereof, or if any indebtedness of
the Borrower in excess of $50,000 (other than to the Lender and other than the
Hawaii Litigation as set forth in Section 5.02(c) hereof) is not paid, when due

<PAGE>

petition seeking reorganization of the Borrower or appointing a receiver,
trustee, custodian or liquidator of the Borrower of all or a substantial part of
the assets of the Borrower, and such order, judgment or decree shall continue
unstayed and in effect for any period of thirty (30) days;

            (h) final judgment for the payment of money in excess of an
aggregate of Fifty Thousand Dollars ($50,000) shall be rendered against the
Borrower, and the same shall remain undischarged for a period of thirty (30)

       writing of such successor within ten (10) days of such appointment;

       then and in every such Event of Default and at any time thereafter during
       the continuance of such event, the Note and any and all other
       indebtedness of the Borrower to the Lender, shall immediately become due
       and payable, both as to principal and interest, without presentment,
       demand, protest or notice of any kind, all of which are hereby expressly
       waived, anything contained herein or in the Note or other evidence of
       such indebtedness to the contrary notwithstanding.

and then such waiver or consent shall be effective only in the specific
instance, and for the purpose, for which given. No notice to, or demand, on the
Borrower, in any case, shall entitle the Borrower to any other or future notice

            Section 7.05. Neither any failure nor any delay on the part of the
Lender in exercising any right, power or privilege hereunder, or under the Note,

                              TERM PROMISSORY NOTE

$250,000.00                                             Providence, Rhode Island
                                                        September 21, 1998

            FOR VALUE RECEIVED, NETWORK SIX, INC., a Rhode Island corporation
with its principal office at 475 Kilvert Street, Warwick, Rhode Island 02886
(herein called the "Maker"), hereby promises to pay to the order of BUSINESS
DEVELOPMENT COMPANY OF RHODE ISLAND, a Rhode Island corporation (herein called
the "Payee"), at its office located at 40 Westminster Street, Suite 702,
Providence, Rhode Island 02903, the principal sum of Two Hundred Fifty Thousand
and 00/100 Dollars ($250,000.00), with interest at the effective rate of ten and
one-quarter percent (10.25%) per annum (the "Interest Rate"). Principal payments
shall be made in fifty-nine (59) consecutive monthly payments ("Installments")
in the sum of Four Thousand One Hundred Sixty-Seven and 00/100 Dollars
($4,167.00), beginning on the 1st day of November, 1998, and payable on the same
day of each successive month or the next business day, and with a sixtieth
(60th) Installment being equal to the remaining unpaid principal plus accrued
interest being due and payable on October 1, 2003.

            Interest on the unpaid principal balance shall be payable monthly,
beginning on the 1st day of November, 1998, and continuing on the same day of
each successive month or the next business day thereafter if such day is not a
business day until the principal has been repaid in full. Each monthly
Installment shall be applied first to the payment of accrued interest owing to
the date received and the remainder to the reduction of principal.
<PAGE>

            Monthly Installments shall be automatically debited on each due date
from the Maker's operating checking account with the bank or financial
institution with which the Maker maintains its accounts.

            Interest shall be calculated and payable whether before or after
maturity of this Note. Interest shall be calculated on the basis of a year
consisting of three hundred sixty (360) days counting the actual number of days
elapsed.

            All past due Installments, or any portion thereof, not paid when
due, if permitted by law, shall bear interest from such due date at the Interest
Rate plus three hundred (300) basis points per annum ("Default Rate"). During
the existence of any Event of Default, as defined in the hereinbelow referenced
Loan Agreement, and after acceleration of this Note by the holder hereof, the
entire unpaid balance of principal and interest of this Note shall bear interest
at the Default Rate.

            If the Maker fails to pay any Installment due hereunder when such
Installment is due and payable, whether at the due date thereof or due to
acceleration or otherwise, a late fee equal to five percent (5.0%) of the
overdue payment shall be immediately due and payable with respect to each late
Installment by the Maker to the Payee hereunder.

            This Note is the "Note" referred to in that certain Term Loan
Agreement of even date herewith between the Payee and the Maker (the "Loan
Agreement") and is subject to optional prepayments and to acceleration of the
maturity hereof, all as provided in said Loan Agreement, which is hereby
incorporated by reference herein and made a


                                       2
<PAGE>

part hereof. This Note, including but not limited to amounts owed pursuant to
the principal balance and interest, is secured, inter alia, by certain "Security
Documents" referred to in said Loan Agreement, and is entitled to the benefits
thereof.

            In case an Event of Default, as defined in said Loan Agreement,
shall occur and be continuing, this Note, including the principal balance and
all interest accrued hereon and thereon, shall at the option of the holder of
this Note become due and payable in the manner and with the effect provided in
said Loan Agreement.

            In the event that the holder of this Note shall exercise or endeavor
to exercise any of its remedies hereunder or under said Loan Agreement or any
agreements securing this Note, the Maker shall pay all reasonable costs and
expenses incurred in connection therewith, including without limitation,
reasonable attorneys' fees, and the holder hereof may take judgment for all such
amounts in addition to all other sums due hereunder.

            The Maker hereby waives presentment, dishonor, protest and demand,
diligence, notice of protest, demand and of dishonor, and any other notice
otherwise required to be given under the law in connection with the delivery,
acceptance, performance, default, enforcement or collection of this Note, and
expressly agrees that this Note or any payment hereunder may be extended or
subordinated, by forbearance or otherwise, from time to time, without in any way
affecting the liability of the Maker. No consent or waiver by the holder hereof
with respect to any action or failure to act which, without such consent or
waiver, would constitute a breach of any


                                        3
<PAGE>

provision of this Note, shall be valid and binding unless in writing and signed
by both the Maker and the holder hereof.

            All agreements between the Maker and the Payee 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 the Payee for the use, forbearance or
detention of the indebtedness evidenced hereby exceed the maximum permissible
interest rate 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. If, from any circumstance whatsoever, fulfillment of any
provision hereof or of the Loan Agreement or of any agreements securing this
Note at the time performance of such provision shall be due, shall involve
transcending the limit of validity prescribed by law, then ipso facto, the
obligation to be fulfilled shall be reduced to the limit of such validity, and
if from any circumstance the Payee 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 the Maker and the Payee.

            This Note shall be construed in accordance with and governed by the
laws of the State of Rhode Island, except to the extent that such laws are
superseded by Federal enactments.

                              TERM PROMISSORY NOTE

$250,000.00                                       Providence, Rhode Island
                                                  September 21, 1998

            FOR VALUE RECEIVED, NETWORK SIX, INC., a Rhode Island corporation
with its principal office at 475 Kilvert Street, Warwick, Rhode Island 02886
(herein called the "Maker"), hereby promises to pay to the order of BUSINESS
DEVELOPMENT COMPANY OF RHODE ISLAND, a Rhode Island corporation (herein called
the "Payee"), at its office located at 40 Westminster Street, Suite 702,
Providence, Rhode Island 02903, the principal sum of Two Hundred Fifty Thousand
and 00/100 Dollars ($250,000.00), with interest at the effective rate of ten and
one-quarter percent (10.25%) per annum (the "Interest Rate"). Principal payments
shall be made in fifty-nine (59) consecutive monthly payments ("Installments")
in the sum of Four Thousand One Hundred Sixty-Seven and 00/100 Dollars
($4,167.00), beginning on the 1st day of November, 1998, and payable on the same
day of each successive month or the next business day, and with a sixtieth
(60th) Installment being equal to the remaining unpaid principal plus accrued
interest being due and payable on October 1, 2003.

      Interest on the unpaid principal balance shall be payable monthly,
beginning on the 1st day of November, 1998, and continuing on the same day of
each successive month or the next business day thereafter if such day is not a
business day until the principal has been repaid in full. Each monthly
Installment shall be applied first to the payment of accrued interest owing to
the date received and the remainder to the reduction of principal.
<PAGE>

            Monthly Installments shall be automatically debited on each due date
from the Maker's operating checking account with the bank or financial
institution with which the Maker maintains its accounts.

            Interest shall be calculated and payable whether before or after
maturity of this Note. Interest shall be calculated on the basis of a year
consisting of three hundred sixty (360) days counting the actual number of days
elapsed.

            All past due Installments, or any portion thereof, not paid when
due, if permitted by law, shall bear interest from such due date at the Interest
Rate plus three hundred (300) basis points per annum ("Default Rate"). During
the existence of any Event of Default, as defined in the hereinbelow referenced
Loan Agreement, and after acceleration of this Note by the holder hereof, the
entire unpaid balance of principal and interest of this Note shall bear interest
at the Default Rate.

            If the Maker fails to pay any Installment due hereunder when such
Installment is due and payable, whether at the due date thereof or due to
acceleration or otherwise, a late fee equal to five percent (5.0%) of the
overdue payment shall be immediately due and payable with respect to each late
Installment by the Maker to the Payee hereunder.

            This Note is the "Note" referred to in that certain Term Loan
Agreement of even date herewith between the Payee and the Maker (the "Loan
Agreement") and is subject to optional prepayments and to acceleration of the
maturity hereof, all as provided in said Loan Agreement, which is hereby
incorporated by reference herein and made a


                                        2
<PAGE>

part hereof. This Note, including but not limited to amounts owed pursuant to
the principal balance and interest, is secured, inter alia, by certain "Security
Documents" referred to in said Loan Agreement, and is entitled to the benefits
thereof.

            In case an Event of Default, as defined in said Loan Agreement,
shall occur and be continuing, this Note, including the principal balance and
all interest accrued hereon and thereon, shall at the option of the holder of
this Note become due and payable in the manner and with the effect provided in
said Loan Agreement.

            In the event that the holder of this Note shall exercise or endeavor
to exercise any of its remedies hereunder or under said Loan Agreement or any
agreements securing this Note, the Maker shall pay all reasonable costs and
expenses incurred in connection therewith, including without limitation,
reasonable attorneys' fees, and the holder hereof may take judgment for all such
amounts in addition to all other sums due hereunder.

            The Maker hereby waives presentment, dishonor, protest and demand,
diligence, notice of protest, demand and of dishonor, and any other notice
otherwise required to be given under the law in connection with the delivery,
acceptance, performance, default, enforcement or collection of this Note, and
expressly agrees that this Note or any payment hereunder may be extended or
subordinated, by forbearance or otherwise, from time to time, without in any way
affecting the liability of the Maker. No consent or waiver by the holder hereof
with respect to any action or failure to act which, without such consent or
waiver, would constitute a breach of any


                                        3
<PAGE>

provision of this Note, shall be valid and binding unless in writing and signed
by both the Maker and the holder hereof.

            All agreements between the Maker and the Payee 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 the Payee for the use, forbearance or
detention of the indebtedness evidenced hereby exceed the maximum permissible
interest rate 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. If, from any circumstance whatsoever, fulfillment of any
provision hereof or of the Loan Agreement or of any agreements securing this
Note at the time performance of such provision shall be due, shall involve
transcending the limit of validity prescribed by law, then ipso facto, the
obligation to be fulfilled shall be reduced to the limit of such validity, and
if from any circumstance the Payee 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 the Maker and the Payee.

            This Note shall be construed in accordance with and governed by the
laws of the State of Rhode Island, except to the extent that such laws are
superseded by Federal enactments.

CLAIM, OR COUNTERCLAIM, WHETHER IN CONTRACT OR TORT, AT LAW OR IN EQUITY,
ARISING OUT OF OR IN ANY WAY RELATED TO THIS NOTE.

            IN WITNESS WHEREOF, the Maker has caused this Note to be executed by
its duly authorized officer as of the day and year first above written.

extent that such taxes, assessments and charges shall be contested in good faith

or ordinance.

      Section 6. Records Relating to Collateral.

      The Debtor will keep its records concerning the Collateral, including the
Customer Receivables and all chattel paper included in the Customer Receivables,
at its office at 475 Kilvert Street,

<PAGE>

Warwick, Rhode Island, or at such other place or places of business as the
Secured Party may approve in writing. The Debtor will hold and preserve such
records and chattel paper and will permit representatives of the Secured Party
at any time during normal business hours upon reasonable notice to examine and
inspect the Collateral and to make abstracts from such records and chattel
paper, and will furnish to the Secured Party such information and reports
regarding the Collateral as the Secured Party may from time to time reasonably

      Section 7. Collections with Respect to Customer Receivables

      Subject to the rights of senior lien holders, the Debtor will, at its
expense, and subject at all times to the Secured Party's right following the
occurrence and during the continuation of an Event of Default to give directions
and instructions:

            (i) endeavor to collect or cause to be collected from customers
      indebted on Customer Receivables, as and when due, any and all amounts,
      including interest, owing under or on account of each Customer Receivable;
      and

            (ii) take or cause to be taken such appropriate action to repossess
      goods, the sale or rental of which gave rise to any Customer Receivable,
      or to enforce any rights or liens under Customer Receivables, as the
      Debtor or the Secured Party may deem proper, and in the name of the
      Debtor, or the Secured Party, as the Secured Party may deem proper;


                                        7
<PAGE>

provided that (x) the Debtor will use its best judgment to protect the interests
of the Secured Party and (y) the Debtor shall not be required under this Section
7 to take any action which would be contrary to any applicable law or court
order or inconsistent with the requirements of any senior lien holder. Subject
to the rights of senior lien holders, the Debtor shall, at the request of the
Secured Party following the occurrence of an Event of Default, notify the
account debtors of the Security Interests of the Secured Party in any of the
Customer Receivables and the Secured Party may itself at any such time so notify
account debtors. The Secured Party shall have full power at any time after such
notice to collect, compromise, endorse, sell or otherwise deal with any or all
outstanding Customer Receivables or the proceeds thereof in the name of either
the Secured Party or the Debtor. In the event that, after notice to any account
debtors to pay the Secured Party, Debtor receives any payment on a Customer
Receivable, any such payments shall be held by Debtor in trust for Secured Party
and immediately turned over to Secured Party as aforesaid.

      Section 8. General Authority.

      The Debtor hereby irrevocably appoints the Secured Party the Debtor's true
and lawful attorney, with full power of substitution, in the name of the Debtor,
the Secured Party or otherwise, for the sole use and benefit of the Secured
Party,


                                        8
<PAGE>

but at the Debtor's expense, to the extent permitted by law to exercise, at any
time and from time to time after any Event of Default has occurred and is
continuing, all or any of the following powers with respect to all or any of the
Collateral (which power shall be in addition and supplemental to any powers,
rights and remedies of the Secured Party described herein):

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

            (ii) to receive, take, endorse, assign and deliver any and all
      checks, notes, drafts, documents and other negotiable and non-negotiable
      instruments and chattel paper taken or received by the Secured Party in
      connection therewith,

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

            (iv) to sell, transfer, assign or otherwise deal in or with the same
      or the proceeds or avails thereof or the related goods securing the
      Customer Receivables, as fully and effectually as if the Secured Party
      were the absolute owner thereof,

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


                                        9
<PAGE>

            (vi) to discharge any taxes, liens, security interests or other
      encumbrances at any time placed thereon;

provided that the Secured Party shall give the Debtor not less then ten (10)
days' prior written notice of the time and place of any sale or other intended
disposition of any of the Collateral, except any Collateral which is perishable
or threatens to decline speedily in value or is of the type customarily sold on
a recognized market. The Secured Party and the Debtor agree that such notice
constitutes "reasonable notification" within the meaning of Section 9-504(3) of
the Uniform Commercial Code.

      Section 9. Events of Default.

      The Debtor shall be in default under this Security Agreement upon the
occurrence of any one of the following events (herein referred to as an "Event
of Default"):

            (a) default by the Debtor in the due observance or performance of
      any covenant or agreement contained herein or breach by the Debtor of any
      representation or warranty herein contained and such non-observance or
      non-performance shall have continued for more than twenty (20) days after
      written notice thereof by the Secured Party to the Debtor;

            (b) any default in the payment when due, after any applicable grace
      period of the principal of, or interest on, any Obligations; or

            (c) the occurrence of any event of default, after any applicable
      grace period, under the provisions of the Loan


                                       10
<PAGE>

      Agreement or any agreements now or hereafter securing the Note.

      Section 10. Remedies Upon Event of Default

      If any Event of Default shall have occurred, the Secured Party may
exercise all the rights and remedies of a Secured Party under the Uniform
Commercial Code (whether or not the Uniform Commercial Code is in effect in the
jurisdiction where such rights and remedies are exercised) and, in addition, the
Secured Party may, without being required to give any notice, except as herein
provided or as may be required by mandatory provisions of law, (i) apply the
cash, if any, then held by it as Collateral in the manner specified in Section
12, and (ii) if there shall be no such cash or if such cash shall be
insufficient to pay all the Obligations in full, sell the Collateral, or any
part thereof, at public or private sale or at any broker's board or on any
securities exchange, for cash, upon credit or for future delivery, and at such
price or prices as the Secured Party may reasonably deem satisfactory. The
Secured Party may require the Debtor to assemble all or any part of the
Collateral and make it available to the Secured Party at a place to be
designated by the Secured Party which is reasonably convenient. Any holder of an
Obligation may be the purchaser of any or all of the Collateral so sold at any
public sale (or, if the Collateral is of a type customarily sold in a recognized
market or is of a type which is


                                       11
<PAGE>

the subject of widely distributed standard price quotations, at any private
sale) and thereafter hold the same, absolutely, free from any right or claim of
whatsoever kind. Upon any such sale the Secured Party shall have the right to
deliver, assign and transfer to the purchaser thereof the Collateral so sold.
Each purchaser at any such sale shall hold the Collateral so sold absolutely,
free from any claim or right of whatsoever kind, including any equity or right
of redemption of the Debtor. Debtor to the extent permitted by law hereby
specifically waives all rights of redemption, stay or appraisal which it has or
may have under any rule of law or statute now existing or hereafter adopted. At
any such sale the Collateral may be sold in one lot as an entirety or in
separate parcels, as the Secured Party may determine. The Secured Party shall
not be obligated to make such sale pursuant to any such notice. The Secured
Party may, without notice or publication, adjourn any public or private sale or
cause the same to be adjourned from time to time by announcement at the time and
place fixed for the sale, and such sale may be made at any time or place to
which the same may be adjourned. In case of any sale of all or any part of the
Collateral on credit or for future delivery, the Collateral so sold may be
retained by the Secured Party until the selling price is paid by the purchaser
thereof, but the Secured Party shall not incur any liability in case of the
failure of such purchaser to take up and pay for the Collateral so sold and, in
case of any such failure, such Collateral may again be sold upon like notice.
The Secured


                                       12
<PAGE>

Party, instead of exercising the power of sale herein conferred upon it, may
proceed by a suit or suits at law or in equity to foreclose the Security
Interests and sell the Collateral, or any portion thereof, under a judgment or
decree of a court or courts of competent jurisdiction.

      Section 11. Right of Secured Party to Use and Operate Tangible
      Collateral, Etc.

      Upon the occurrence and during the continuation of an Event of Default, to
the extent permitted by law, the Secured Party shall have the right and power to
take possession of all or any part of the Tangible Collateral, and to exclude
the Debtor and all persons claiming under the Debtor wholly or partly therefrom,
and thereafter to hold, store, and/or use, operate, manage and control the same.
Upon any such taking of possession, the Secured Party may, from time to time, at
the expense of the Debtor, make all such repairs, replacements, alterations,
additions and improvements to and of the Tangible Collateral as the Secured
Party may deem proper. In such case, the Secured Party shall have the right to
manage and control the Tangible Collateral and to carry on the business and to
exercise all rights and powers of the Debtor in respect thereto as the Secured
Party shall deem best, including the right to enter into any and all such
agreements with respect to the leasing and/or operation of the Tangible
Collateral or any part thereof as the Secured Party may see fit; and the Secured
Party shall be entitled to collect and receive all rents, issues, profits, fees,
revenues


                                       13
<PAGE>

and other income of the same and every part thereof. Such rents, issues,
profits, fees, revenues and other income shall be applied to pay the expenses of
holding and operating the Tangible Collateral and of conducting the business
thereof, and of all maintenance, repairs, replacements, alterations, additions
and improvements, and to make all payments which the Secured Party may be
required or may elect to make, if any, for taxes, assessments, insurance and
other charges upon the Tangible Collateral or any part thereof, and all other
payments which the Secured Party may be required or authorized to make under any
provision of this Security Agreement (including reasonable legal costs and
attorney's fees). The remainder of such rents, issues, profits, fees, revenues
and other income shall be applied to the payment of the Obligations in such
order or priority as the Secured Party shall determine (subject to the
provisions of Section 12 hereof) and, unless otherwise provided by law or by a
court of competent jurisdiction, any surplus shall be paid over to the Debtor.

      Section 12. Application of Collateral and Proceeds.

      The proceeds of any sale of, or other realization upon, all or any part of
the Collateral shall be applied in the following order of priorities:

            (a) first, to pay the expenses of such sale or other realization,
      including reasonable commission to the Secured Party's agent, and any
      other unreimbursed expenses for which


                                       14
<PAGE>

      the Secured Party is to be reimbursed pursuant to Section 13 as the
      Secured Party in its sole discretion reasonably exercised shall determine;

            (b) second, to the payment of the Obligations in such other manner
      as the Secured Party, in its sole discretion, shall determine; and

            (c) finally, to pay to the Debtor, or its successors or assigns, or
      to a court of competent jurisdiction, or as directed by a court of
      competent jurisdiction, and surplus then remaining from such proceeds.

      Section 13. Expenses: Secured Party's Lien.

      The Debtor will forthwith upon demand pay to the Secured Party:

            (i) the amount of any taxes which the Secured Party may have been
      required to pay by reason of the Security Interests (including any
      applicable transfer taxes) or to free any of the Collateral from any lien
      thereon, excepting senior liens and liens set forth on Exhibit C to the
      Loan Agreement, and

            (ii) the amount of any and all reasonable out-of-pocket expenses,
      including the reasonable fees and disbursements of its counsel and of any
      agents not regularly in its employ, which the Secured Party reasonably may
      incur in connection with (w) the preparation and administration of this
      Security Agreement, (x) the collection, sale or other


                                       15
<PAGE>

      disposition of any of the Collateral, (y) the exercise by the Secured
      Party of any of the powers conferred upon it hereunder, or (z) any default
      on the Debtor's part hereunder.

      Section 14. Termination of Security Interests; Release of Collateral.

      Upon the repayment and performance in full of all the Obligations, the
Security Interests shall terminate and all rights to the Collateral shall revert
to the Debtor. Upon any such termination of the Security Interests or release of
Collateral, the Secured Party will, at the Debtor's expense to the extent
permitted by law, execute and deliver to the Debtor such documents as the Debtor
shall reasonably request to evidence the termination of the Security Interests
or the release of such Collateral, as the same may be.

      Section 15. Notices

      All notices, communications and distributions hereunder shall be given or
made to the parties as set forth in the Loan Agreement.

      Section 16. Waivers, Non-Exclusive Remedies.

      No failure on the part of the Secured Party to exercise, and no delay in
exercising, and no course of dealing with respect to, any right, power or remedy
under this Security Agreement shall operate as a waiver thereof; nor shall any
single or partial


                                       16
<PAGE>

exercise by the Secured Party of any right, power or remedy under this Security
Agreement preclude any other right, power or remedy. The remedies in this
Security Agreement are cumulative and are not exclusive of any other remedies
provided by law. The Debtor and the Secured Party each also waives trial by jury
in any action brought on or with respect to this Security Agreement.

      Section 17. Changes in Writing.

      Neither this Security Agreement nor any provision hereof may be changed,
waived, discharged or terminated orally but only by a statement in writing
signed by the party against which enforcement of the change, waiver, discharge
or termination is sought.

      Section 18. Rhode Island Law; Meaning of Terms.

      This Security Agreement shall be construed in accordance with and governed
by the laws of the State of Rhode Island, except as otherwise required by
mandatory provisions of law and except to the extent that remedies provided by
the laws of any State other than Rhode Island are governed by the laws of said
State. Unless otherwise defined herein, or unless the context otherwise
requires, all terms used herein which are defined in the Rhode Island Uniform
Commercial Code have the meanings therein stated.


                                       17
<PAGE>

      Section 19. Separability.

      If any provision hereof is invalid or unenforceable in any jurisdiction,
the other provisions hereof shall remain in full force and effect in such
jurisdiction and shall be liberally construed in favor of the Secured Party.

      Section 20. Headings.

      The headings in this Security Agreement are for the purposes of reference
