and SANJAY MODY ("Mody"), on behalf of himself and as agent for the benefit of
Earl Anderson (collectively, the "Co-Pledgors" and each a "Co-Pledgor"), for the
benefit of TWINKLE INTERNATIONAL FZE, an United Arab Emirates company
("Pledgee"), and THELEN REID & PRIEST LLP, a California limited liability
partnership, as Agent ("Agent").

                                   WITNESSETH

         WHEREAS, Distinctive Devices, Inc., a Delaware corporation ("DDI"), and
the Pledgee have entered into a Note Purchase Agreement, dated the date hereof
(the "Purchase Agreement"), in which the Pledgee has agreed to loan (the "Loan")
to DDI the principal amount of US$4,000,000 pursuant to an Unsecured Promissory
Note (the "Note");

         WHEREAS, the Co-Pledgors and Earl Anderson ("Anderson") are executive
officers and directors of DDI and its wholly-owned subsidiary galaxis technology
ag, a German corporation, and hold options (the "Options") to purchase shares of
DDI Common Stock, $.001 par value ("Common Stock"), pursuant to option
agreements (the "Option Agreements"), as set forth on Schedule A hereto;

         WHEREAS, to induce the Pledgee to enter into the Purchase Agreement and
to make the Loan, each Co-Pledgor is willing to pledge the Pledged Collateral
(defined below) in furtherance of the obligations of DDI under the Note,
pursuant to the terms specified herein;

         WHEREAS, Anderson has pledged and delivered his Option Agreement, with
its respective Notice of Assignment duly executed in favor of the Pledgee, to
the Agent, with the intention that it constitute part of the Pledged Collateral,
and has asked Mody to act as his agent under this Agreement, and accordingly,
Mody shall make the representations, warranties and covenants contained herein
on Anderson's behalf, with respect to his portion of the Pledged Collateral; and

         WHEREAS, the Co-Pledgors have a direct interest in the financial
affairs and well being of DDI and its subsidiaries and will benefit from the
Loan contemplated by the Purchase Agreement, and accordingly, each Co-Pledgor
desires to execute and deliver this Agreement;

         NOW, THEREFORE, in consideration of the foregoing and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Co-Pledgors and Pledgee hereby agree as follows:

         1.  Pledge and Grant of Security Interests.
             --------------------------------------

             1.1  Grant. Each of the Co-Pledgors hereby pledges, assigns,
hypothecates and transfers to Pledgee, its successors and assigns, for the
benefit of Pledgee, his respective Option Agreement representing the respective
Options, together with a Notice of Assignment duly executed in favor of the
Pledgee ("Pledged Collateral"), as collateral security for the payment or other
satisfaction by DDI of its indebtedness (the "DDI Indebtedness") under the Note.





             1.2  Delivery. Each Co-Pledgor shall deliver or cause to be
delivered to the Agent his portion of the Pledged Collateral.

         2.  Obligations Unconditional. The obligations of the Co-Pledgors under
this Agreement, which are limited solely to the Pledged Collateral, shall be
absolute and unconditional and shall remain in full force and effect until the
DDI Indebtedness shall have been paid in full or otherwise satisfied. Such
obligations of the Co-Pledgors shall not be affected, modified or impaired by
any statement of facts or by the happening from time to time of any event, such
as modification or extension of the Note, whether or not such event shall occur
with notice to, or the consent of, any of the Co-Pledgors.

         3.  Waiver of Co-Pledgors. Each of the Co-Pledgors hereby waives notice
of the issuance of the Note. Each of the Co-Pledgors also waives presentment,
demand for payment, protest and notice of nonpayment or dishonor and all other
notices and demands whatsoever relating to the Note, other than notice of an
Event of Default thereunder and notices as required by this Agreement.

         4.  Use of Collateral. Prior to payment in full of the Note, each
Co-Pledgor shall be entitled to exercise the Options, in whole or in part, with
respect to the Pledged Collateral. In the event a Co-Pledgor exercises the
Options, in whole or in part, he shall cause DDI to deliver the certificates for
the shares of DDI Common Stock issued upon such exercise to the Agent to be held
as additional Pledged Interests under this Agreement.

         5.  Representations and Warranties. To induce the Pledgee to make the
Loan and enter into this Agreement, and for other good and valuable
consideration, each Co-Pledgor hereby represents and warrants to with the
Pledgee that:

             (a) he has full legal power and authority to enter into this
Agreement and to perform his obligations herein;

             (b) this Agreement constitutes the legal, valid and binding
obligation of such Co-Pledgor, enforceable in accordance with its terms, except
as such enforceability may be affected by bankruptcy, insolvency, moratorium or
similar laws affecting the enforcement of creditors' rights generally and by
general principles of equity (regardless of whether enforcement is sough in a
proceeding in equity or at law);

             (c) the execution, delivery and performance of this Agreement does
not and will not violate or contravene any agreement, commitment, arrangement or
instrument to which, as of any date, he is a party; and

             (d) he is the exclusive legal and beneficial owner of his Option
Agreement, free and clear of all claims, liens, security interests and other
encumbrances, other than restrictions on transfer under the Securities Act of
1933, as amended, with respect to the Options and the underlying shares of
Common Stock ("Option Shares").


                                       2



         6.  Co-Pledgors' Covenants.
             ----------------------

             6.1  No Other Pledges. Each Co-Pledgor covenants and agrees that he
will not create, incur or permit to exist any pledge, lien, mortgage,
hypothecation, security interest, charge, option or any other encumbrance with
respect to any of his portion of the Pledged Collateral, or any of such
Co-Pledgor's Option Shares, or any proceeds thereof, prior to the satisfaction
of the Note.

             6.2  No Transfer. Each Co-Pledgor covenants and agrees that he will
not transfer, assign, hypothecate, encumber, pledge or otherwise alienate his
portion of the Pledged Collateral, or enter into any agreement with respect to
the foregoing, including, without limitation, any of such Co-Pledgor's Option
Shares, prior to satisfaction of the Note.

             6.3  Further Assurance. Each Co-Pledgor covenants and agrees that
he will, upon the reasonable request of the Pledgee, execute and deliver all
such instruments and agreements as may be necessary or appropriate to give
effect to his obligations under this Agreement.

         7.  Rights and Remedies upon Default. The Pledgee shall have the
following rights and remedies:

             7.1  Rights. If any Event of Default under the Note shall occur,
and is still continuing for five (5) Business Days (a "Business Day" being any
weekday, not otherwise a bank holiday in New York City), which has not been
otherwise waived in writing, the Pledgee shall notify ("Default Notice") each
Co-Pledgor and the Agent in writing of such Event of Default and its intention
to obtain the transfer of the Pledged Collateral. If no notice objecting to the
Event of Default or the transfer of the Pledged Collateral ("Notice of
Objection"), made in good faith, is received by both the Agent and the Pledgee,
from any of the Co-Pledgors within seven (7) Business Days from the date each
such Default Notice is received by the respective Co-Pledgors, the Agent shall
deliver to the Pledgee the Pledged Collateral. The Agent shall have no duty to
sell or otherwise realize the Pledged Collateral. If any Notice of Objection is
received that objects to the transfer of all or a portion of the Pledged
Collateral pursuant to this Section 7, the Agent shall retain that portion of
the Pledged Collateral specified in any such Notice of Objection, until such
objection is resolved (a) through a final resolution and agreement among the
Co-Pledgors and the Pledgee indicated by a joint written instruction of the
Co-Pledgors and the Pledgee to the Agent, or (b) in a final unappealable order
of a court of competent jurisdiction. Notwithstanding anything in this Agreement
to the contrary, the Pledgee understands that upon an Event of Default by DDI
under the Note, the Pledged Collateral shall represent the Pledgee's only
recourse against the Co-Pledgors (including Anderson) in respect of this
Agreement and the Note, as the Pledgee shall have no recourse against any
Co-Pledgor (including Anderson) for an obligation or claim arising out of or
based upon the Agreement other than as to the Pledged Collateral.

             7.2  Application of Pledged Collateral. The Options and the Option
Shares, if any, received by the Pledgee pursuant to this Agreement shall be
applied to the DDI Indebtedness, valued as agreed between the Pledgee and DDI.
This Agreement is entered into by the Co-Pledgors for the benefit of the
Pledgee, and its successors and assigns, as the Pledgee of the Note and may be


                                       3



enforced by any subsequent Pledgee of the Note in accordance with the provisions
of this Agreement. This Agreement shall not be deemed to create any right in, or
to be in whole or in part for the benefit of, any person other than such
Pledgee, the Co-Pledgors, DDI and their respective successors, assigns, heirs
and administrators.

         8.  Release of Pledged Collateral. Upon payment in full and satisfac-
tion of the Note, the Pledgee shall promptly take all action necessary to
terminate the security interest in the Pledged Collateral, and the Agent shall
deliver to each Co-Pledgor his portion of the Pledged Collateral, including
returning Anderson his portion of the Pledged Collateral.

         9.  Agent. Acceptance by the Agent of its duties under this Agreement
is subject to the following terms and conditions, which the parties to this
Agreement hereby agree shall govern and control the rights, duties and
immunities of the Agent:

             (a)  the duties and obligations of the Agent shall be determined
solely by the express provisions of this Agreement (except and to the extent
otherwise expressly provided herein) and the Agent shall not be bound by the
provisions of any other agreement;

             (b)  notwithstanding anything to the contrary herein, the duties
and obligations of the Agent hereunder shall extent only to the delivery of the
Pledged Collateral pursuant to Sections 7.1 and 8 above and such duties and
obligations will terminate upon such delivery;

             (c)  the Agent shall not be responsible for any failure or
inability of the parties to this Agreement, or of anyone else, to deliver any of
the Pledged Collateral, including Option Shares which may become Pledged
Collateral, or other property to the Agent or otherwise to honor any of the
provisions of this Agreement;

             (d)  the Agent shall be fully protected in acting on and relying
upon any written notice, direction, request, waiver, consent, receipt or other
paper or document which the Agent in good faith believes to be genuine and to
have been signed or presented by the proper party or parties from time to time;

             (e)  the Agent shall not be liable for any error of judgment, or
for any act done or step taken or omitted by it in good faith or for any mistake
in fact or law, or for anything which it may do or refrain from doing in
connection herewith, except its own willful misconduct or gross negligence;

             (f)  the Agent may seek the advice of legal counsel in the event of
any dispute or question as to the construction of any of the provisions of this
Agreement or its duties hereunder, and it shall incur no liability and shall be
fully protected in respect of any action taken, omitted or suffered by it in
good faith in accordance with the written opinion of such counsel; and

             (g)  in the event of ambiguity in the provisions governing the
Note, the Pledged Collateral or this Agreement or uncertainty on the part of the
Agent as to how to proceed, such that the Agent, in its sole and absolute
judgment, deems it necessary for its protection so to do, the Agent may refrain
from taking any action other than to retain custody of the Pledged Collateral


                                       4



deposited hereunder until it shall have received joint written instructions
signed by the Pledgee and each Co-Pledgor in accordance with the provisions of
this Agreement.

         10. Resignation or Removal of Agent.
             -------------------------------

             10.1  The Agent may resign at any time by giving thirty (30) days'
written notice thereof to the Pledgee and each Co-Pledgor. Within thirty (30)
days after receiving such notice, the Pledgee and each Co-Pledgor shall appoint
a successor escrow agent (the "Successor Agent") at which time the Agent shall
deliver the Pledged Collateral to the Successor Agent. After appointment of the
Successor Agent and delivery of the Pledged Collateral by the Agent to the
Successor Agent, the Agent shall have no further duties or responsibilities in
connection herewith.

             10.2  The Pledgee and each Co-Pledgor, acting jointly, may remove
the Agent upon written notice to the Agent stating such removal and designating
a Successor Agent, and, upon delivery of the Pledged Collateral to the Successor
Agent, the Agent shall thereupon be discharged from all obligations under this
Agreement and shall have no further duties or responsibilities in connection
herewith.

             10.3  If after thirty (30) days from the date of delivery of its
written notice of intent to resign, or of the parties joint notice of removal,
the Agent has not received a written designation of a Successor Agent, the
Escrow Agent's sole responsibility shall be in its sole discretion either to
retain custody of the Pledged Collateral, or to apply to a court of competent
jurisdiction for appointment of a Successor Agent and after such appointment to
have no further duties or responsibilities in connection herewith.

             10.4  The Pledgee acknowledges that the Agent is acting as legal
counsel to DDI and to the Co-Pledgors. The Pledgee does not object to the
representation of DDI and the Co-Pledgors by the Agent.

         11. Indemnity. The Pledgee and each Co-Pledgor will, jointly and
severally, keep the Agent harmless and will indemnify the Agent to the fullest
extent permitted by law against any claim, action, suit or demand, which may be
brought or made against the Agent and any of its partners, employees or agents
(each an "Indemnified Party") in connection with the performance by the Agent in
its role as Agent in accordance with the terms of this Agreement and will pay
any reasonable cost and expense (including without limitation reasonable
attorneys' fees payable in advance) incurred by an Indemnified Party in
connection with this indemnity, as and when incurred, except to the extent (if
any) for matters arising out of the gross negligence or intentional misconduct
of the Agent.

         12. Expenses. Unless otherwise indicated in this Agreement, the Pledgee

disposition without the Pledgee's written consent shall be void. All of the


                                       5



rights, privileges, remedies and options given to Pledgee under this Agreement
and the Note shall inure to the benefit of any successors and assigns, and all
