THIS DEBENTURE AND THE SHARES OF COMMON STOCK UNDERLYING THIS DEBENTURE
(COLLECTIVELY, THE "SECURITIES") HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED, ASSIGNED OR OTHERWISE

No.  1                                                        US $ 400,000.
Dated:  December 27, 2001

                           DISTINCTIVE DEVICES, INC.
                           10% CONVERTIBLE DEBENTURE

   FOR VALUE RECEIVED, Distinctive Devices, Inc., a New York corporation (the
"Company"), hereby promises to pay to the order of LINK ASSETS LIMITED, a
limited liability company under the laws of the Isle of Jersey, the registered
holder hereof (the "Holder"), the principal sum of Four Hundred Thousand US
Dollars (US $400,000) five (5) years from the date hereof (the "Maturity Date")
and to pay interest on the principal sum outstanding, at the rate of ten percent
(10%) per annum, semi-annually on the last day of June and December, commencing
June 30, 2002 until maturity or otherwise satisfied in full.  All interest will
be paid to the person in whose name this Debenture (or one or more predecessor
Debentures) is registered on the records of the Company regarding registration
and transfers of the Debentures (the "Debenture Register"), provided, however,
that the Company's obligation to a transferee of this Debenture arises only if
such transfer, sale or other disposition is made in accordance with the terms
and conditions of the Subscription Agreement executed by the original Holder.
Subject to the provisions herein, the principal of, and interest on, this
Debenture are payable at the address last appearing on the Debenture Register of
the Company as designated in writing by the Holder from time to time.

   This Debenture is one of a duly authorized issue of up to $2,400,000 in
principal amount of Debentures of the Company, designated as 10% Convertible
Debenture (hereinafter the "Debentures"). The Debentures were initially issued
as part of a private placement by the Company of up to 600,000 units (the
"Units") pursuant to the terms of a Subscription Agreement, among the Company
and the original Holders.  Each Unit consisted of (i) $4.00 principal amount of
Debentures and (ii) shares of Common Stock, $.05 par value, of the Company (the
"Common Stock").

   This Debenture is subject to the following additional provisions:

    1.     Exchanges.  This Debenture is exchangeable for an equal aggregate
principal amount of Debentures of different authorized denominations, as
requested by the Holder surrendering the same.  No service charge will be made
for such registration or transfer or exchange.

    2.     Transfer.  This Debenture has been issued subject to investment
representations of the original Holder hereof and may be transferred or
exchanged only in compliance with the Securities Act of 1933, as amended (the
"Securities Act"), and other applicable state and foreign securities laws.  The
Holder shall send the form of Assignment attached hereto as Exhibit A duly
executed with the Debenture to the Company.  In the event of any proposed
transfer of this Debenture or issue of shares of Common Stock upon conversion
hereof to a person other than the Holder, the Company may require, prior to
issuance of a new Debenture or the shares of Common Stock in the name of such
other person, that it receive reasonable transfer documentation, including
opinions, that the issuance of the Debenture or the shares of Common Stock in
such other name does not and will not cause a violation of the Securities Act or
any applicable state or foreign securities laws.  Prior to due presentment for
transfer or conversion of this Debenture, the Company and any agent of the
Company may treat the person in whose name this Debenture is duly registered on
the Company's Debenture Register as the owner hereof for the purpose of
receiving payment as herein provided and for all other purposes, whether or not
this Debenture be overdue, and neither the Company nor any such agent shall be
affected by notice to the contrary.

   3.     Conversion.

     3.01 Right to Convert.  The Holder of this Debenture is entitled, at his
option, to convert at any time commencing upon the date hereof and continuing
until the Debenture is repaid in full or as provided in Article 4 herein, all or
part of the then outstanding principal amount of this Debenture into shares of
Common Stock of the Company (the "Conversion Shares"), at a conversion price for
each share of Common Stock (the "Conversion Price") based upon the year from
initial issuance during which the Company receives the notice of conversion (the
"Conversion Notice"), as set forth below, subject to adjustment pursuant to
Section 5 hereof:


                      Year                   Conversion Price Per Share
                      ----                   --------------------------

                      First                  $0.25
                      Second                 $0.37 1/2
                      Third                  $0.50
                      Fourth                 $0.62 1/2
                      Fifth                  $0.75

Unpaid interest, if any, accrued or accruing from the date of issuance to the
Conversion Date (as defined) shall, at the option of the Company, be paid in
cash or shares of Common Stock upon conversion at the then Conversion Price.  No
fraction of shares or certificate representing fractions of shares will be
issued on conversion, but the number of shares issuable shall be rounded to the
nearest whole share.

     3.02 Notice of Conversion.  Conversion shall be effectuated by surrendering
the Debentures to be converted to the Company with the form of Conversion Notice
attached hereto as Exhibit B, executed by the Holder of the Debenture evidencing
the Holder's intention to convert this Debenture.  The date on which notice of
conversion is duly given (the "Conversion Date") shall be deemed to be the date
on which the Holder has delivered this Debenture, with a duly executed
Conversion Notice, to the Company.  As soon as practicable after receipt of the
aforementioned documents, the Company shall issue and deliver to the Holder (or
such other person designated in the Conversion Notice), a certificate or
certificates for the full number of shares of Common Stock issuable upon the
conversion.

     3.03 Partial Conversion.  If less than the entire principal amount of this
Debenture is to be converted, upon the conversion the Company shall issue a new
Debenture to the Holder in a principal amount equal to unconverted principal
amount of this Debenture when converted.

     3.04 Reservation of Shares.  The Company shall reserve out of its
authorized but unissued shares of Common Stock (or shares held in treasury)
enough shares of Common Stock to permit the conversion of this Debenture upon
shareholder approval of an increase in the number of authorized shares of Common
Stock.  All shares of Common Stock which may be issued upon conversion of this
Debenture shall be validly issued, fully paid and non-assessable.

   4.     Redemption.

     4.01 Right to Redeem.  The Company shall have the right to redeem this
Debenture at any time, in whole or in part, commencing one (1) year from the
date hereof, at a redemption price (the "Redemption Price"), (expressed in
percentages of the principal amount) set forth below, plus accrued and unpaid
interest to the redemption date (the "Redemption Date").  If redeemed during the
periods indicated below, the applicable redemption percentage would be:

                      Year                   Percentage
                      ----                   ----------

                      Second                 105.00%
                      Third                  103.75%
                      Fourth                 102.50%
                      Fifth                  101.25%

     4.02 Notice of Prepayment.  Notice of prepayment of this Debenture shall be
given to the Holder at his address as specified in the Debenture Register at
least fifteen (15) days prior to the date fixed for such prepayment.  The notice
of redemption shall state (i) the Redemption Date, (ii) the Redemption Price,
(iii) the Conversion Price and the date that the right to convert would
terminate, and (iv) the place where the Debenture is to be surrendered for
redemption.  Upon notice of prepayment being given as aforesaid, the Company
covenants and agrees that it will pay on the Redemption Date the amount payable
on the redemption together with all accrued and unpaid interest thereon.

     4.03 Debenture to Become Due on Date Called for Redemption.  If this
Debenture is called for redemption, then this Debenture shall become due and
payable on the Redemption Date stated in such notice and shall cease to bear
interest on and after such Date, and the only right of the Holder will be to
receive the Redemption Price, unless, upon presentation, the Company shall fail
to redeem this Debenture.

     4.04 Partial Redemption.  If less than the principal amount of all
outstanding Debentures are to be redeemed, the redemption shall be pro rata on
each Debenture equal to the percentage the aggregate redemption amount
(excluding accrued and unpaid interest) bears to the aggregate principal amount
of all outstanding Debentures.  Upon surrender of this Debenture upon a partial
redemption, the Company shall issue a new Debenture to the Holder in a principal
amount equal to the unredeemed principal amount of this Debenture when
surrendered.

   5.     Anti-dilution.

     5.01 Adjustment.  The Conversion Price shall be subject to adjustment from
time to time as follows:

     (a)   If the number of shares of Common Stock outstanding at any time after
the date hereof is increased by a stock dividend or other distribution of
securities to the Company's stockholders without consideration (other than a
distribution of rights to purchase securities for cash) payable in shares of
Common Stock or by a subdivision or split-up of shares of Common Stock, then,
immediately following the record date fixed for the determination of holders of
Common Stock entitled to receive such stock dividend, said other distribution,
subdivision or split-up, the number of Conversion Shares and the Conversion
Price of this Debenture shall be appropriately adjusted so that the number of
Conversion Shares shall be increased and the Conversion Price decreased in
proportion to such increase of outstanding shares.

     (b)   If the number of shares of Common Stock outstanding at any time after
the date hereof is decreased by a combination or reverse stock split of the
outstanding shares of Common Stock, then, immediately following the record date
for such combination or reverse split, the number of Conversion Shares and the
Conversion Price of this Debenture shall be appropriately adjusted so the number
of Conversion Shares shall be decreased and the Conversion Price shall be
increased in proportion to such decrease in outstanding shares.

     5.02 Determination.  Any adjustment required by Section 5.01 shall be made
by the Company which adjustment shall be conclusive to the Holder.  Upon a
determination of an adjustment pursuant to this Section, the Company shall send
notice to the Holder specifying the new number of Conversion Shares and the
Conversion Price, and the reason and calculation for the adjustment.

     5.03 Consolidation, Merger and Sale of Assets.  If the Company merges or
consolidates with another corporation or sells or transfers all or substantially
all of its assets to another person and the holders of the Common Stock are
entitled to receive stock, securities or property in respect of or in exchange
for Common Stock, then as a condition of such merger, consolidation, sale or
transfer, the Company and any such successor, purchaser or transferee shall
amend this Debenture to provide that it may thereafter be converted on the terms
and subject to the conditions set forth above into the kind and amount of stock,
securities or property receivable upon such merger, consolidation, sale or
transfer by a holder of the number of shares of Common Stock into which this
Debenture might have been converted immediately before such merger,
consolidation, sale or transfer, subject to adjustments which shall be as nearly
equivalent as may be practicable.  In the event of any proposed merger,
consolidation or sale or transfer of all or substantially all of the assets of
the Company (a "Sale"), the Holder hereof shall receive notice from the Company
of such Sale at least fifteen (15) days prior to the proposed effective date of
the Sale.  The notice shall disclose the Holder's rights in respect of such
Sale, and have the right to convert by delivering a Notice of Conversion to the
Company prior to the effective date of the Sale.

   6.     Subordination.

     6.01 Senior Indebtedness.  The rights of the Holder hereof to the principal
sum or portion of principal, and the interest due on this Debenture are and
shall remain subject and subordinate to the prior payment of the principal of
(and premium and fees, if any) and interest on (i) all existing or future
obligations of the Company for money borrowed from any bank, trust company or
other financial institution engaged in the business of lending money, and (ii)
any modifications, renewals, extensions or refundings of the foregoing
(hereinafter called the "Senior Indebtedness").

     6.02 Effect of Subordination.  Upon receivership, insolvency, assignment
for the benefit of creditors (whether or not pursuant to bankruptcy or other
insolvency laws), sale of all or substantially all of the assets and liabilities
of the Company, (i) no amount shall be paid by the Company in respect of the
principal of or interest on this Debenture at the time outstanding, unless and
until the principal of and interest on the Senior Indebtedness then outstanding
shall have been paid in full, and (ii) no claim or proof of claim shall be filed
with the Company by or on behalf of the Holder of this Debenture which shall
assert any right to receive any payments in respect of the principal of and
interest on this Debenture, except subject to the payment in full of the
principal of and interest on all of the Senior Indebtedness then outstanding.

     6.03 Rights of Holder.  No provision of this Debenture shall alter or
impair the obligation of the Company, which is absolute and unconditional, to
pay the principal of, and interest on, this Debenture at the time, place, and
rate, and in the coin or currency, herein prescribed, nor shall anything herein
prevent the Holder from exercising all remedies otherwise permitted to him by
applicable law or hereunder upon the occurrence of any Event of Default, subject
to the rights, if any, of the holders of Senior Indebtedness.  The Holder shall
be entitled to assume that no event which would give rise to subordination under
this Section 6 has occurred unless the Company or any holder of Senior
Indebtedness shall have given notice to the Holder or the Holder has otherwise
received notice of such event.  This Debenture is unsecured.  This Debenture and
all other Debentures now or hereafter issued of similar terms are direct
obligations of the Company.  This Debenture ranks equally with all other
Debentures included in the Units, and shall be senior to any other indebtedness
of the Company (including trade debt) other than the Senior Indebtedness.

   7.     Securities Laws.  The Holder of the Debenture, by acceptance hereof,
agrees that this Debenture is being acquired for investment and that such Holder
will not offer, sell or otherwise dispose of this Debenture or the Conversion
Shares except under circumstances which will not result in a violation of the
Securities Act or any applicable state Blue Sky or foreign laws or similar laws
relating to the sale of securities.  If at the time of the conversion of this
Debenture no registration statement under the Securities Act with respect to the
Conversion Shares is in effect, the Holder will make such representations and
warranties as were made in the Subscription Agreement regarding his acquisition
of the Conversion Shares.

   8.     Event of Default.

     8.01 Events.  The existence of any one or more of the following events
shall constitute an "Event of Default":

     (a)   the Company shall fail to pay within thirty (30) days of the due date
           any sum due in respect of principal or interest thereon in respect of
           this Debenture or any of the other Debentures included in the Units,
           whether at maturity, by redemption or otherwise; or

     (b)   the Company shall fail to perform or observe, in any material
           respect, any other covenant, term, provision, condition, agreement or
           obligation of the Company under this Debenture and such failure shall
           continue uncured for a period of thirty (30) days after notice from
           the Holder of such failure; or

      (c)  the Company shall fail to perform or observe, in any material
           respect, any covenant, term, provision, condition, agreement or
           obligation of the Company under any Senior Indebtedness and the
           holder thereof has demanded acceleration of the principal amount of
           such Senior Indebtedness, and such demand for acceleration shall not
           have been waived or rescinded; or

      (d)   the Company shall (i) admit in writing its inability to pay its
            debts generally as they mature; (ii) make an assignment for the
            benefit of creditors or commence proceedings for its dissolution; or
            (iii) apply for or consent to the appointment of a trustee,
            liquidator or receiver for its or for a substantial part of its
            property or business; or

      (e)   a trustee, liquidator or receiver shall be appointed for the Company
            or for a substantial part of its property or business without its
            consent and shall not be discharged within ninety (90) days after
            such appointment; or

      (f)   any governmental agency or any court of competent jurisdiction at
            the instance of any governmental agency shall assume custody or
            control of the whole or any substantial portion of the properties or
            assets of the Company and shall not be dismissed within ninety (90)
            days thereafter; or

      (g)   proceedings for bankruptcy, reorganization, insolvency or
            liquidation proceedings or other relief under any bankruptcy law or
            any law for the relief of debtors shall be instituted by or against
            the Company and, if instituted against the Company, shall not be
            dismissed within ninety (90) days after such institution or the
            Company shall by any action or answer approve of, consent to, or
            acquiesce in any such proceedings or admit the material allegations
            of, or default in answering a petition filed in any such proceeding.

     8.02 Remedies.  Upon the occurrence and continuation of an Event of
Default, unless such Event of Default shall have been waived in writing by the
Holder (which waiver shall not be deemed to be a waiver of any subsequent
default) the holders of not less than a majority of the principal amount of
Debentures then outstanding may, by written notice to the Company, declare the
Debenture immediately due and payable, without presentment, demand, protest or
notice of any kind, anything herein or in any other Debenture to the contrary
notwithstanding, and thereafter the Holder may immediately, and without
expiration of any period of grace, enforce any and all of the Holder's rights
and remedies provided herein or any other rights or remedies afforded by law,
subject to Section 6 hereof regarding subordination.

   9.     Benefits.  This Debenture shall be binding upon the Company and its
successors and assigns and shall inure to the benefit of the Holder and his
heirs, administrators, successors and assigns, provided that the Holder may
transfer all or part of the unpaid principal amount of this Debenture to a
member of his immediate family, to a trust of which the Holder or a member of
his immediate family is the beneficiary, or to a corporation or other entity
wholly-owned by the Holder.

   10.     Amendments and Waivers.

     10.01 Consent.  With the written consent of the holders of at least a
majority of the then aggregate principal amount of the outstanding Debentures,
any covenant, agreement or condition of the Debentures may be waived by the
holders (either generally or in a particular instance and either retroactively
or prospectively), or such holders and the Company may from time to time enter
into agreements for the purpose of amending any covenant, agreement or condition
of the Debentures or changing in any manner the rights of the Holders; provided,
however:

     (a)   no such amendment or waiver shall (i) change the stated maturity of
           this Debenture or reduce the interest rate, or reduce the amount of
           the principal hereof, or (ii) adversely, as to the Holder, change or
           modify the terms under which this Debenture may be converted pursuant
           to Section 3 hereof, or (iii) reduce the percentage of holders of
           Debentures required to approve any such amendment or effectuate any
           such waiver, without the consent of all of the holders of Debentures
           then outstanding; and

     (b)   no such waiver shall extend or effect any obligation not expressly
           waived or impair any right consequent thereon.

     10.02 Application.  Any such amendment or waiver shall apply equally to all
holders of Debentures, including the Holder, and shall be binding upon them,
upon each future Holder and upon the Company, whether or not such Debenture
shall have been marked to indicate such amendment or waiver, but any Debenture
issued thereafter shall bear a notation referring to any such amendment or
continuing waiver.

   11.     Notices.  All communications and notices provided for herein shall be
