                     INSTRUMENT OF ASSUMPTION OF LIABILITIES

      This Instrument of Assumption of Liabilities dated as of December 29, 1999
is made by Intrinsix Canada Co., a Nova Scotia unlimited company (the "Buyer"),
in favor of Telexis Corp., a corporation continued under the laws of Canada (the
"Seller"). All capitalized words and terms used in this Instrument of Assumption
of Liabilities and not defined herein shall have the respective meanings
ascribed to them in the Asset Purchase Agreement dated as of December 29, 1999,
among the Seller and the Buyer (the "Agreement").

      WHEREAS, pursuant to the Agreement, the Seller has agreed to sell,
transfer, convey, assign and deliver to the Buyer substantially all of the
assets and business associated with the Seller's Business referred to in the
Agreement; and

      WHEREAS, in partial consideration therefor, the Agreement requires the
Buyer to assume certain of the liabilities of the Seller;

      NOW, THEREFORE, in consideration of the mutual promises set forth in the
Agreement and other good and valuable consideration, the receipt of which is
hereby acknowledged, the Buyer hereby agrees as follows:

      1. The Buyer hereby assumes and agrees to perform, pay and discharge all
of the Assumed Liabilities.

      2. Notwithstanding the foregoing, the Buyer does not assume or agree to
perform, pay or discharge, and the Seller shall remain unconditionally liable
for, all obligations, liabilities and commitments, fixed or contingent, of the
Seller other than the Assumed Liabilities.

      3. Nothing contained herein shall require the Buyer to perform, pay or
discharge any liability, obligation or commitment expressly assumed by the Buyer
herein so long as the Buyer in good faith contests or causes to be contested the
amount or validity thereof, subject, however, to the provisions of Paragraph 6
below.

      4. Nothing herein shall be deemed to deprive the Buyer of any defenses,
set-offs or counterclaims which the Seller may have had or which the Buyer shall
have with respect to any of the obligations, liabilities and commitments hereby
assumed (the "Defenses and Claims"). The Seller hereby transfers, conveys and
assigns to the Buyer all Defenses and Claims and agrees to cooperate with the
Buyer to maintain, secure, perfect and enforce such Defenses and Claims,
including the signing of any documents, the giving of any testimony or the
taking of any such other action as is reasonably requested by the Buyer in
connection with such Defenses and Claims.

      5. It is expressly understood and agreed that all liabilities, obligations
and commitments not assumed hereunder by the Buyer pursuant to Paragraph 1 above
shall remain the sole obligation of the Seller and its respective successors and
assigns.
<PAGE>

      6. The Buyer agrees to indemnify and hold harmless the Seller from and
against all claims, damages, losses, liabilities, costs and expenses, including
without limitation reasonable attorneys' fees, with respect to the failure of
the Buyer to pay, discharge or otherwise satisfy or perform, when due, the
liabilities, obligations and commitments hereby assumed by the Buyer.

      7. The Buyer, by its execution of this Instrument of Assumption of
Liabilities, and the Seller, by its acceptance of this Instrument of Assumption
of Liabilities, each hereby acknowledges and agrees that neither the
representations and warranties nor the rights, obligations or remedies of either
party under the Agreement shall be deemed to be enlarged, modified or altered in
any way by such execution and acceptance of this instrument.

      IN WITNESS WHEREOF, the Buyer and the Seller have caused this instrument
to be duly executed under seal as of the date first above written.

     using the Shared Facility, to vehicles or their contents or any other
     property on them, for any damage to property entrusted to its or their

          the Licensee's property under which any person other than the Licensee
          attempts to take or occupy any of the Licensee's rights under this
          license, and the execution or attachment is not set aside, vacated,
          discharged or bonded within fifteen days after it issues, or

     (e)  the Licensee attempts to execute a bulk sale or remove the bulk of its
          fixtures from the Shared Facility,

     this license may at the option of the Licensor be cancelled, whether the
     term has commenced or any moneys have been prepaid or not, by delivering to
     the Licensee notice to that effect, and upon such delivery this license
     shall cease, but without prejudice to any rights of the Licensor which had
     accrued before the cancellation.

     right contained in the lease, or shall request that the Licensor relocate

          to an appropriate adjustment in the license fee);

     (b)  the Licensor shall provide at its expense leasehold improvements in
          the Relocated Premises to a standard equal to the leasehold
          improvements in the Shared Facility;

     (c)  the Licensor shall pay for the actual, reasonable, direct moving costs
          of the Licensee from the Shared Facility to the Relocated Premises;
          and

          shall be amended and the Relocated Premises shall deemed to be the
          Shared Facility;

          of receiving notice of such intended relocation) to terminate this
          License as of the date of the intended relocation; and

          of the Shared Facility designated as the Intrinsix Premises as set
          forth in Schedule C attached hereto.

     The Licensor acknowledges that relocation of the Licensee would cause
     disruption to the business of the Licensee, and accordingly, the Licensor
     will use reasonable efforts (not involving the expenditure of money) to
     avoid such relocation including, if practical, providing the Licensee with
     an opportunity to negotiate a lease of the Shared Facility with the
     Landlord.

     acknowledge that;

     (a)  the license has been freely negotiated by both parties; and

     (b)  that in any controversy, dispute or contest over the meaning,
          interpretation, validity or enforceability of this license or of any
          of its terms and conditions, there shall be no inference, presumption
          or conclusion drawn whatsoever against either party by virtue of that
          party having drafted this license or any portion thereof.

(7)  ASSIGNMENT BY LICENSOR.  In the event of the assignment, sale, lease or
     sublease by the Licensor of its interest in the Premises or the portion of
     it containing the Shared Facility or the assignment by the Licensor of this
     license or any interest of

     Any Party may give any notice, request, demand, claim or other
     communication hereunder using any other means (including personal delivery,
     expedited courier, messenger service, telecopy, telex, ordinary mail or
     electronic mail), but no such notice, request, demand, claim or other

     Party or Parties notice in the manner herein set forth.

(9)  SUBORDINATION OF LICENSE.  This license is subject and subordinate to all
     mortgages, deeds of trust, or security interests which may now or at any
     time after it takes effect affect the license in whole or in part or the
     Licensor's interest in the Shared Facility in whole or in part, and whether
     any such mortgages, deeds of trust, or security interests shall affect only
     the license or the Licensor's interest in the Shared Facility or shall
     affect other premises as well, and the Licensee shall at any time upon
     notice from the Licensor become a licensee of a mortgagee or trustee under
     any such mortgage or deed of trust upon the same terms and

                                      -8-
<PAGE>

     conditions as are herein set forth. This license shall also be subject and
     subordinate to all renewals, modifications, consolidations, replacements
     and extensions of any mortgages, deeds of trust, or security interests and
     in confirmation of such subordination the Licensee shall execute promptly
     upon request by the Licensor all certificates, instruments of postponement
     or other instruments which may from time to time be requested, to give
     effect thereto.

(10) CONTINUANCE OF LICENSE.  If the Licensee continues to exercise the license
     granted after the expiration of its term without objection by the Licensor
     and without any written agreement providing otherwise, it shall be deemed
     to be a licensee from month to month terminable on 30 days written notice,
     and subject to the provisions of this license in so far as the same are
     applicable (including fees), but it shall be lawful for the Licensor to
     cancel and determine the license granted by delivering to the Licensee
     notice to that effect, and upon delivery of such notice the license shall
     cease without prejudice to any rights of the Licensor under this license
     accrued before the cancellation.

(11) ACCESS TO SHARED FACILITY --  Each Party covenants and agrees that it will
     not (and will instruct all of its employees, agents and representatives who
     have access to the Shared Facility not to):

     (i)   interfere with the business or property of each Party, except as
           expressly provided;

     (ii)  disclose any confidential information which was made available to it
           as a result of its access to the Shared Facility pursuant to this
           Agreement or

     (iii) make any material alterations to the Facility without the prior
           written consent of the other Party.

     Either Party will be entitled to an injunction, restraining order or other
     equitable relief from any court of competent jurisdiction in the event of
     any breach by the other of this proviso. The rights and remedies provided
     by this proviso are cumulative and in addition to any other rights and
     remedies either Party may have at law or equity.

(12) NON-WAIVER OF DEFAULT.  The waiver or acquiescence by the Licensor or the
     Licensee of or in any breach by the other party of any covenant or
     condition shall not be deemed to be a waiver of the covenant or condition
     or any subsequent or other breach of any covenant or condition of this
     license.

(13) SEVERABILITY.  Any term or provision of this License that is invalid or
     unenforceable in any situation in Ontario shall not affect the validity or
     enforceability of the remaining terms and provisions hereof or the validity
     or enforceability of the offending term or provision in any other situation
     or in any other jurisdiction.  If the final judgment of a court of
     competent jurisdiction declares that any term or provision hereof is
     invalid or unenforceable, the Parties agree that the court making the
     determination of invalidity or unenforceability shall have the power to
     reduce the scope, duration or area of the term or provision, to delete
     specific words or phrases, or to replace any invalid or unenforceable term
     or provision with a term or provision that is valid and

                                      -9-
<PAGE>

     enforceable and that comes closest to expressing the intention of the
     invalid or unenforceable term or provision, and this License shall be
     enforceable as so modified after the expiration of the time within which
     the judgment may be appealed.

(14) AREA - The Licensor and the Licensee acknowledge that the Shared Facility
     has an area of approximately 10,808.5 rentable square feet and that the
     Premises contain an area of approximately 44,416.2 rentable square feet,
     and accordingly (subject to adjustment in area pursuant to the provisions
     of Lease) unless otherwise provided herein, the fee payable to the Licensor
     by the Licensee shall be 12.1673% of the total occupancy costs payable by
     the Licensor in connection with the Premises.

(15) INTEREST --  In the event that either of the Parties defaults in its
     obligation to make any payment hereunder, the defaulting Party shall pay
     the other Party interest at the prime rate in effect from time to time at
     the Royal Bank of Canada for Canadian dollar loans, plus two percent.

(16) Renewal - Provided that the Licensee is not in default in the performance
     of its obligations under this License, the Licensee shall have the option
     (to be exercised no later than September 20, 2000) of renewing this license
     for a period of one year upon the same terms and conditions as are
     contained herein, save and except for this right of renewal.

(17) Waiver of Subrogation -  In the event of damage to the property of the
     Licensor or the Licensee from fire, lightning, explosion and all perils
     defined in a standard policy of fire insurance and additional perils, the
     parties agree to look solely to their respective insurers, and each party
     hereby waives any right of subrogation which their respective insurers may
     have against the other party, whether or not such damage results from the
     negligence or other fault of the other party, its servants, agents, or
     contractors.

(18) ALLOCATION OF SPACE -  Unless otherwise agreed, the Licensor and the
     Licensee shall have exclusive use of those portions of the Shared Facility
     designated as "Telexis Premises" and "Intrinsix Premises" respectively on
     Schedule C attached hereto, and shall each have free access to the portion
     of the Shared Facility designated as "Common Premises" thereon.

(19) LAW.  This License Agreement shall be governed by the laws of the Province
     of Ontario.

(20) HEADINGS.  The section headings contained in this License are inserted for
     convenience only and shall not affect in any way the meaning or
     interpretation of this Agreement.

building or any part of it or any tenant or any Licensee in it shall be
increased by reason of the Licensee's use of the Shared Facility, the Licensee
shall indemnify the Licensor from all costs, charges and expenses imposed upon
the Licensor as a result thereof.
