principal (or installment thereof) of, or interest on, any such Indebtedness,
the Lender will have the right, in its discretion, to pay such interest or
principal for the account of the Borrower and be reimbursed by the Borrower
therefor;

      (o) The Borrower will notify the Lender immediately if it becomes aware of
the occurrence of any Event of Default or of any fact, condition, or event that
only with the giving of notice or passage of time or both, could reasonably

of ERISA, (ii) terminate any pension plan (as defined in Section 3 of ERISA) in

payment when due of all amounts which, under the provisions of any pension plan

or modify any such existing plan for employees subject to ERISA, which plan or
modification provides any benefits based on past service, without the advance
consent of the Lender to the amount of the aggregate past service liability
thereby created; and

      (r) The Borrower will maintain all of its primary depository accounts with
the Lender.

                                    ARTICLE 8
                        THE LENDER'S RIGHTS AND REMEDIES

8.1   The Lender's Rights Upon Default

      Upon the occurrence of an Event of Default and at any time thereafter, the
Lender, without presentment, demand, notice, protest or advertisement of any
kind, will have the following rights.

8.2   Account Debtors

      Upon the occurrence of an Event of Default and at any time thereafter, (i)
the Lender may notify account debtors, at the Borrower's expense, that the
Collateral has been assigned to the Lender and that payments will be made
directly to the Lender, (ii) upon request of the Lender, the Borrower will
notify such account debtors that their accounts must be paid to the Lender,
(iii) at the request of the Lender, the Borrower will hold all checks, drafts,
cash and other remittances in trust for the Lender and deliver them in kind to
the Lender, and (iv) the Lender will 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 the Borrower.

8.3   Possession and Foreclosure of Collateral

      Upon the occurrence of an Event of Default and at any time thereafter, to
the extent that the Borrower could legally do so, the Lender may, in the
Lender's sole discretion (i) enter onto, occupy and use any premises owned by
the Borrower or in which the Borrower has any interest, (ii) take possession of
all Collateral, (iii) operate and use the Equipment, complete work in process
and sell Inventory without being liable to the Borrower on account of any
losses, damage or depreciation that may occur as a result thereof (so long as
the Lender acts in good faith), and (iv) lease or license the Collateral to any
Person for such purposes. In any event, the Lender may sell, lease, assign and
deliver the whole or any part of the Collateral, at public or private sale, for
cash, upon credit or for future delivery, at such prices and upon such terms as
the Lender deems advisable. The Lender may sell or lease Collateral alone or in
conjunction with other property, real or personal, and allocate the sale
proceeds or leases among the items of Collateral sold

                                       23
<PAGE>

without the necessity of the Collateral being present at any such sale, or in
view of prospective purchasers thereof. If notice of sale is legally required,
the Borrower agrees that ten (10) days written notice will be deemed reasonable.
Upon a public sale, the Lender may become the purchaser of the whole or any part
of the Collateral sold, discharged from all claims and free from any right of
redemption. In case of any such sale by the Lender of all or any of the
Collateral on credit, or for future delivery, such Collateral so sold may be
retained by the Lender until the selling price is paid by the purchaser. The
Lender will incur no liability in case of the failure of the purchaser to take
possession and pay for the Collateral so sold. In case of any such failure, the
said Collateral may be resold. Any Collateral remaining unsold after being
offered at public auction may be abandoned or disposed in a commercially
reasonable manner.

      In any event, at any time and from time to time the Lender may abandon the
Collateral or any part thereof in a commercially reasonable manner. The Borrower
agrees immediately upon demand to take possession of any and all abandoned
Collateral and to remove it from any location in the possession of or under the
control of the Lender.

8.4   Use of Intellectual Property

      Upon the occurrence of an Event of Default and at any time thereafter, the
Lender may (i) use all or any part of the Intellectual Property which the
Borrower now has or may hereafter acquire, and (ii) license such Intellectual
Property to third parties, seek registration of such Intellectual Property in
any state or nation or prosecute pending applications for patent, trademark, or
service marks in the Borrower's name in any state or nation.

8.5   Notification of Default to Third Parties

      Upon the occurrence of an Event of Default and at any time thereafter, the
Lender may notify the Borrower's suppliers, account debtors and other third
parties of the default and of any and all decisions made and actions taken by
the Lender with respect to this Agreement, the Obligations or the Collateral,
without liability of any kind, except for actions taken by the Lender in bad
faith or in a grossly negligent manner.

8.6   Assembly of Collateral

      Upon the occurrence of an Event of Default and at any time thereafter, the
Lender may require the Borrower to assemble the Collateral in a single location
at a place to be designated by the Lender and make the Collateral at all times
secure and available to the Lender.

8.7   Lien, Set-off.

      The Borrower hereby grants to the Lender, a lien, security interest and
right of setoff as security for the Obligations, upon and against all deposits,
credits, collateral and property, now or hereafter in the possession, custody,
safekeeping or control of the Lender. At any time, without demand or notice, the
Lender may set off the same or any part thereof and apply the same to any of the
Obligations even though unmatured and regardless of the adequacy of any other
collateral securing the Obligations. ANY AND ALL RIGHTS TO REQUIRE THE LENDER TO
EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH
SECURES THE OBLIGATIONS, PRIOR TO EXERCISING ITS

                                       24
<PAGE>

RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF THE
BORROWER, ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED.

8.8   Exercise of Other Remedies

      Upon the occurrence of any Event of Default and at any time thereafter,
the Lender may exercise the remedies of a Lender afforded by the Uniform
Commercial Code and other applicable law or by the terms of any agreement,
including the Collateral Documents, between the Borrower and the Lender.

8.9   Cumulative Rights and Remedies

      All rights and remedies of the Lender, whether provided for herein or in
other agreements, instruments or documents or conferred by law, are cumulative
and may be exercised alone or simultaneously.

                                    ARTICLE 9
                                ATTORNEY-IN-FACT

9.1   Attorney-In-Fact

      After the occurrence of an Event of Default, after the Lender determines,
in a commercially reasonable manner, that the Collateral is at risk, the
Borrower hereby irrevocably appoints the Lender, or its designee, as the
Borrower's true and lawful attorney-in-fact, with full power, as follows: (i) to
endorse the name of the Borrower on any assignments, notes, checks, drafts,
money orders, or other instruments of payment for Collateral; (ii) to sign or
endorse the name of the Borrower on any negotiable instrument, invoice, freight
or express bill, bill of lading, storage or warehouse receipts, drafts,
assignments, verifications and notices in connection with accounts; (iii) to
obtain, adjust, settle and cancel, in the Borrower's name, insurance policies
and to sign the Borrower's name on settlement checks or drafts; (iv) in the
Borrower's name, to do any act which this Agreement requires Borrower to do,
and, (v) to give notice to the United States Post Office to effect changes of
address so that mail addressed to the Borrower may be delivered directly to the
Lender. In exercising this power-of-attorney, the Lender will not be liable to
the extent that it acts in good faith, and does not act in a grossly negligent
manner.

                                   ARTICLE 10
                                  MISCELLANEOUS

10.1  Construction.

      The provisions of this Agreement will be in addition to those of the Note,
the Collateral Documents and any other guaranty, pledge or security agreement,
note, or other evidence of liability now or hereafter held by the Lender, all of
which will be construed as complementary to each other. Nothing herein contained
will prevent the Lender from enforcing any or all other guaranty, pledge or
security agreements, notes, or other evidences of liability in accordance with
their respective terms.

                                       25
<PAGE>

10.2  Further Assurance.

      From time to time, the Borrower will execute and deliver to the Lender
such additional documents and will provide such additional information as the
Lender may reasonably require to carry out the terms of this Agreement and be
informed of the status and affairs of the Borrower.

10.3  Enforcement and Waiver by the Lender.

      The Lender will have the right at all times to enforce the provisions of
this Agreement and the Collateral Documents in strict accordance with the terms
hereof and thereof, notwithstanding any conduct or custom on the part of the
Lender in refraining from so doing at any time or times. The failure of the
Lender at any time or times to enforce its rights under such provisions,
strictly in accordance with the same, will not be construed as having created a
custom in any way or manner contrary to specific provisions of this Agreement or
as having in any way or manner modified or waived the same. All rights and
remedies of the Lender are cumulative and concurrent and the exercise of one
right or remedy will not be deemed a waiver or release of any other right or
remedy.

10.4  Pledge to the Federal Reserve.

      The Lender may at any time pledge all or any portion of its rights under
this Agreement, the Notes and the Collateral Documents 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 enforcement thereof will release the
Lender from its obligations under such documents.

10.5  Usury Laws.

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

10.6  Expenses of the Lender.

                                       26
<PAGE>

      The Borrower will, on demand, reimburse the Lender for all reasonable
expenses, including the reasonable fees and expenses of legal counsel for the
Lender, incurred by the Lender in connection with the preparation,
administration, amendment, modification, or enforcement of this Agreement and
the Collateral Documents and the collection or attempted collection of any of
the Obligations.

10.7  Payments.

      All payments will be in lawful money of the United States in immediately
available funds.

by any applicable Laws, notice of any other action taken by the Lender; and

      (b) Releases the Lender and its officers, attorneys, agents, and employees

any of them except willful misconduct and bad faith or gross negligence.

10.10 Sale to Third Party.

      The Lender will have the unrestricted right at any time or from time to
time, and without any other party's consent, to assign all or any portion of its
rights and obligations hereunder to one or more banks or other financial

that they will 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 the Lender will
deem necessary to effect the foregoing. In addition, at the request of the
Lender and any such Assignee, the Borrower will issue one or more new promissory
notes in the same form as the existing promissory notes, as applicable, to any
such Assignee and, if the Lender has retained any of its rights and obligations
hereunder following such assignment to the Lender, which new promissory notes
will be issued in replacement of, but not in discharge of, the liability
evidenced by the promissory note held by the Lender prior to such assignment and
will reflect the amount of the respective commitments and loans held by such
Assignee and the Lender after giving, effect to such assignment. Upon the
execution and delivery of appropriate assignment documentation, amendments and
any other documentation required by the Lender in connection with such
assignment, and the payment by Assignee of the purchase price agreed to by the
Lender, and such Assignee, such Assignee will be a party to this Agreement and

connection herewith) to the extent that such rights and obligations have been
assigned by the Lender pursuant to the assignment documentation between the
Lender and such Assignee, and the Lender will be released from its obligations
hereunder and thereunder to a corresponding extent. The Borrower will not be
required to pay for the preparation of such new documents. The Lender will use
reasonable efforts to provide copies to the Borrower of any such assignment.

to grant to one or more banks or other financial institutions (each a

                          REVOLVING LINE OF CREDIT NOTE

$1,500,000.00                                           January 13, 2000
                                                        Worcester, Massachusetts

      FOR VALUE RECEIVED, INTRINSIX CORP., a Massachusetts corporation having
its principal place of business at 33 Lyman Street, Westborough, Massachusetts
01581 (the "Borrower") promises to pay to BANKBOSTON, N.A., a national bank
having an office at 100 Front Street, Worcester, Massachusetts 01608 (the
"Lender"), or order, at the Lender's place of business, the principal sum of ONE
MILLION FIVE HUNDRED THOUSAND AND 00/100 DOLLARS ($1,500,000.00), or so much as
may have been advanced to the Borrower and remains unpaid, in lawful money of
the United States of America in immediately available funds, with interest on
the unpaid balance hereof at the rates and in the manner hereafter provided.

      The unpaid principal of this Note from time to time outstanding shall bear
interest, payable monthly in arrears, computed on the basis of the actual number
of days elapsed over a year assumed to have 360 days, at a fluctuating annual
rate equal to the "Base Rate" plus one-half percent (0.50%). "Base Rate" means
the annual rate of interest announced from time to time by the Lender at its
head office as its Base Rate. Any change in the interest rate will become
effective without notice simultaneously with each change by the Lender in its
Base Rate. The Base Rate is a reference rate established by the Lender and does
not necessarily represent the lowest or best rate being charged to any customer.

      Interest shall be payable monthly in arrears, the first such payment of
interest to be due and payable on February 29, 2000 and thereafter on the last
day of each succeeding month. The entire indebtedness evidenced by this Note is
payable immediately upon the occurrence of an Event of Default and in any event
no later than May 31, 2001.

      The Borrower may borrow, repay (without penalty), and reborrow, the
principal hereunder from time to time in accordance with the terms of that
certain Loan and Security Agreement between the Borrower and the Lender of even
date herewith (the "Agreement"), provided that the outstanding principal balance
hereunder shall not exceed the Borrowing Base, as defined in the Agreement. The
proceeds of this Note will be disbursed, if at all, from time to time as set
forth in the Agreement. No advances will be made hereunder after the earlier to
occur of (i) May 31, 2001 or (ii) an Event of Default.

      To the extent that any payment is due on a day which is not a Business
Day, an adjustment will be made in accordance with the Modified Following
Business Day Convention so that the due date will be the first following
Business Day. A "Business Day" means a day on which commercial banks settle
payments in New York.

      Each payment made hereunder shall be applied first to interest then due on
the unpaid balance of principal and then to principal. If the entire amount of
any required principal and/or interest payment is not paid in full within ten
(10) days after the same is due, the Borrower shall

                                       1

pay to the Lender a late fee equal to five percent (5.00%) of the required
payment, excluding sums due after demand or upon acceleration.

      This Note is issued pursuant to the Agreement and is subject to all of the
terms and conditions contained in the Agreement. A default or an Event of
Default under the Agreement shall also constitute an Event of Default hereunder.
At its option, and at any time, after an Event of Default has occurred under the
Agreement or this Note, the Lender may declare all obligations of the Borrower
to the Lender, including without limitation all amounts hereunder, due and
payable as provided herein without further action of any kind, including without
notice, demand or presentment.

      Upon default, after demand, after maturity, after judgment has been
rendered on this Note, or upon the occurrence of an Event of Default, the unpaid
principal of all advances shall, at the option of the Lender, bear interest at a
rate which is four (4) percentage points per annum greater than that which would
otherwise be applicable.

      Any deposits or other sums at any time credited by or due from the Lender
to the Borrower, any endorser or guarantor hereof, may at all times be held and
treated as collateral for the payment of this Note and any and all other
liabilities (direct or indirect, absolute or contingent, sole, joint or several,
secured or unsecured, due or to become due, now existing or hereafter arising)
of any such maker to the holder. The Lender may apply or set-off such deposits
or other sums against such liabilities at any time.

      The Borrower and any guarantor hereby grant to the Lender, a lien,
security interest and right of setoff as security for this Note, upon and
against all deposits, credits, collateral and property, now or hereafter in the
possession, custody, safekeeping or control of the Lender. At any time, without
demand or notice, the Lender may set off the same or any part thereof and apply
the same to any of the Obligations (as defined in the Agreement), even though
unmatured and regardless of the adequacy of any other collateral securing the
Obligations. ANY AND ALL RIGHTS TO REQUIRE THE LENDER 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 THE BORROWER AND ANY GUARANTOR, ARE HEREBY KNOWINGLY,
VOLUNTARILY AND IRREVOCABLY WAIVED.

      The Borrower, guarantors, endorsers or other persons now or hereafter
liable for the payment of any of the indebtedness evidenced by this Note,
severally agree, by making, guaranteeing or endorsing this Note or by making any
agreement to pay any of the indebtedness evidenced by this Note, to waive
presentment for payment, protest and demand, notice of protest, demand and of
dishonor and nonpayment of this Note, and consent, on one or more occasions,
without notice of further assent (a) to the substitution, exchange or release of
the collateral securing this Note or any part thereof at any time, (b) to the
acceptance or release by the holder or holders hereof at any time of any
additional collateral or security for or other guarantors of this Note, (c) to
the modification or amendment, at any time and from time to time, of this Note,
the Agreement or any instrument securing this Note at the request of any person
liable thereon, (d) to the granting by the holder hereof of any extension of the
time for payment of this Note or for the performance of the agreements,
covenants and conditions contained in this Note, the

                                       2
<PAGE>

Agreement or any other instrument securing this Note, at the request of any
person liable thereon, and (e) to any and all forbearances and indulgences
whatsoever. Such consent shall not alter or diminish the liability of any
person.

      The Borrower agrees to pay all reasonable expenses or costs, including
attorneys' fees and costs of collection, which may be incurred by the holder
hereof in connection with the enforcement of any obligations hereunder or
representation with respect to bankruptcy or insolvency proceedings.

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

      The Lender may at any time pledge or assign all or any portion of the
Lender's rights under this Note and the other loan documents to a Federal
Reserve Bank, provided, however, that no such pledge or assignment shall release
the Lender from the Lender's obligations hereunder or any other loan document.

      The obligations of the Borrower hereunder are secured by all assets of the
Borrower as set forth in the Agreement.

      THE LENDER (BY ITS ACCEPTANCE HEREOF) AND THE BORROWER AGREE THAT THEY,
INCLUDING ANY ASSIGNEE OR SUCCESSOR OF THEM, SHALL NOT SEEK A JURY TRIAL IN ANY
LAWSUIT, PROCEEDING, COUNTERCLAIM, OR ANY OTHER LITIGATION PROCEDURE BASED UPON,
OR ARISING OUT OF, THIS NOTE, ANY RELATED INSTRUMENTS, ANY COLLATERAL OR THE
DEALINGS OR THE RELATIONSHIP BETWEEN THEM. THE LENDER AND THE BORROWER SHALL NOT
SEEK TO CONSOLIDATE ANY SUCH ACTION WITH ANY OTHER ACTION IN WHICH A JURY TRIAL
CANNOT BE OR HAS NOT BEEN WAIVED. THE PROVISIONS OF THIS PARAGRAPH HAVE BEEN
FULLY DISCUSSED BY THE LENDER AND THE BORROWER AND THESE PROVISIONS SHALL BE
SUBJECT TO NO EXCEPTIONS. THE LENDER AND THE BORROWER AGREE THAT THE PROVISIONS
OF THIS PARAGRAPH WILL BE FULLY ENFORCED IN ALL INSTANCES.

      Executed as a sealed instrument as of the 13th day of January, 2000.
