                             STOCK PLEDGE AGREEMENT


         This Stock Pledge  Agreement  (this  "Agreement"),  dated as of May 28,
2004, among Laurus Master Fund, Ltd. (the "Pledgee"),  Pacific Biometrics, Inc.,
a Delaware corporation (the "Pledgor").

                                   BACKGROUND

         The Company has entered into a Securities Purchase Agreement,  dated as
of May 28, 2004 (as amended,  modified,  restated or  supplemented  from time to
time,  the  "Securities  Purchase  Agreement"),  pursuant  to which the  Pledgee
provides or will provide certain financial accommodations to the Company.

         In order to induce the  Pledgee to provide or  continue  to provide the
financial  accommodations  described in the Securities Purchase Agreement,  each
Pledgor  has agreed to pledge and grant a security  interest  in the  collateral
described herein to the Pledgee on the terms and conditions set forth herein.

         NOW, THEREFORE, in consideration of the premises and for other good and
valuable consideration the receipt of which is hereby acknowledged,  the parties
hereto agree as follows:

         1.  Defined  Terms.  All  capitalized  terms used herein  which are not
defined  shall  have  the  meanings  given  to them in the  Securities  Purchase
Agreement.

         2.  Pledge  and Grant of  Security  Interest.  To  secure  the full and
punctual  payment  and  performance  of (the  following  clauses  (a)  and  (b),
collectively,  the  "Indebtedness")  (a) the  obligations  under the  Securities
Purchase  Agreement  and the Related  Agreements  referred to in the  Securities
Purchase   Agreement  (the  Securities   Purchase   Agreement  and  the  Related
Agreements, as each may be amended, restated,  modified and/or supplemented from
time to time,  collectively,  the "Documents")  and (b) all other  indebtedness,
obligations  and liabilities of each Pledgor to the Pledgee whether now existing
or hereafter arising, direct or indirect,  liquidated or unliquidated,  absolute
or contingent,  due or not due and whether under,  pursuant to or evidenced by a
note, agreement,  guaranty,  instrument or otherwise (in each case, irrespective
of the genuineness, validity, regularity or enforceability of such Indebtedness,
or of any  instrument  evidencing any of the  Indebtedness  or of any collateral
therefor or of the existence or extent of such  collateral,  and irrespective of
the  allowability,  allowance or  disallowance of any or all of such in any case
commenced  by or  against  any  Pledgor  under  Title 11,  United  States  Code,
including,  without limitation,  obligations or indebtedness of each Pledgor for
post-petition interest,  fees, costs and charges that would have accrued or been
added to the Indebtedness  but for the commencement of such case),  each Pledgor
hereby pledges, assigns, hypothecates,  transfers and grants a security interest
to Pledgee in all of the following (the "Collateral"):

                                      -1-

     (a)  the  shares of stock  set  forth on  Schedule  A  annexed  hereto  and
          expressly made a part hereof  (together with any additional  shares of
          stock or other  equity  interests  acquired  by  Pledgor in such named
          entities,  the "Pledged  Stock"),  the  certificates  representing the
          Pledged Stock and all dividends,  cash, instruments and other property
          or  proceeds  from  time to time  received,  receivable  or  otherwise
          distributed in respect of or in exchange for any or all of the Pledged
          Stock;

     (b)  all  additional  shares of stock of any issuer (each,  an "Issuer") of
          the Pledged Stock from time to time acquired by Pledgor in any manner,
          including,  without  limitation,  stock dividends or a distribution in
          connection    with   any    increase   or    reduction   of   capital,
          reclassification,  merger, consolidation,  sale of assets, combination
          of shares,  stock split,  spin-off or split-off (which shares shall be
          deemed  to  be  part  of  the   Collateral),   and  the   certificates
          representing  such  additional  shares,   and  all  dividends,   cash,
          instruments and other property or proceeds from time to time received,
          receivable or otherwise  distributed  in respect of or in exchange for
          any or all of such shares; and

     (c)  all options and rights,  whether as an addition to, in substitution of
          or in exchange for any shares of any Pledged Stock and all  dividends,
          cash,  instruments  and other  property or proceeds  from time to time
          received,  receivable  or  otherwise  distributed  in respect of or in
          exchange for any or all such options and rights.

     (d)  upon  the   irrevocable   payment  in  full  of  all  obligations  and
          liabilities  of the Company with respect to the Note,  this  Agreement
          shall  terminate and be of no further  force or effect.  Laurus hereby
          agrees to file the  appropriate  financing  statements  and take other
          reasonable  action  required  to effect such  termination  and release
          promptly after receipt of such payment.


     (e)  In  addition,  upon the  release of Laurus'  security  interest in the
          assets of PBI Technology  Inc.  pursuant to and in accordance with the
          terms of the Master Security  Agreement,  Laurus' security interest in
          the stock of PBI Technology Inc. shall also be automatically  released
          from the  Collateral  granted to Laurus  hereunder  and  Laurus  shall
          promptly  return to the Company the stock  certificate  (together with
          all stock  powers  and  endorsements)  and any other  Collateral  with
          respect to the stock of PBI Technology Inc.



         3. Delivery of Collateral.  All certificates representing or evidencing
the  Pledged  Stock  shall be  delivered  to and held by or on behalf of Pledgee
pursuant  hereto  and  shall be  accompanied  by duly  executed  instruments  of
transfer or  assignment  in blank,  all in form and  substance  satisfactory  to
Pledgee.  Pledgor  hereby  authorizes  the Issuer  upon demand by the Pledgee to
deliver  any  certificates,   instruments  or  other  distributions   issued  in
connection with the Collateral  directly to the Pledgee, in each case to be held
by the  Pledgee,  subject  to the terms  hereof.  Upon an Event of  Default  (as
defined  below) under the Note that has occurred  and is  continuing  beyond any
applicable grace period,  the Pledgee shall have the right,  during such time in

                                      -2-
<PAGE>

its discretion and with seven (7) days prior notice to the Pledgor,  to transfer
to or to register in the name of the Pledgee or any of its  nominees  any or all
of the Pledged Stock. In addition, the Pledgee shall have the right at such time
to exchange certificates or instruments representing or evidencing Pledged Stock
for certificates or instruments of smaller or larger denominations.

         4.  Representations  and Warranties of Pledgor.  Pledgor represents and
warrants to the Pledgee (which representations and warranties shall be deemed to
continue to be made until all of the Indebtedness has been paid in full and each
Document and each agreement and instrument entered into in connection  therewith
has been irrevocably terminated) that:

     (a)  the execution,  delivery and  performance by Pledgor of this Agreement
          and the pledge of the Collateral  hereunder do not and will not result
          in any violation of any  agreement,  indenture,  instrument,  license,
          judgment, decree, order, law, statute, ordinance or other governmental
          rule or regulation applicable to Pledgor;

     (b)  this Agreement constitutes the legal, valid, and binding obligation of
          Pledgor  enforceable  against  Pledgor  in  accordance  with its terms
          except  as  limited   by   bankruptcy,   insolvency,   reorganization,
          moratorium or similar law relating to or affecting the  enforcement of
          creditors' rights generally;

     (c)  (i) all  Pledged  Stock  owned by Pledgor  is set forth on  Schedule A
          hereto and (ii)  Pledgor is the  direct and  beneficial  owner of each
          share of the Pledged Stock;

     (d)  all of the  shares of the  Pledged  Stock  have been duly  authorized,
          validly issued and are fully paid and nonassessable;

     (e)  no consent or approval of any person, corporation,  governmental body,
          regulatory  authority or other entity, is or will be necessary for (i)
          the execution,  delivery and performance of this  Agreement,  (ii) the
          exercise by the Pledgee of any rights with  respect to the  Collateral
          or (iii) the  pledge  and  assignment  of, and the grant of a security
          interest in, the Collateral hereunder;

     (f)  there  are  no  pending  or,  to  the  best  of  Pledgor's  knowledge,
          threatened  actions or  proceedings  before any court,  judicial body,
          administrative  agency or arbitrator  which may  materially  adversely
          affect the Collateral;

     (g)  Pledgor  has the  requisite  power and  authority  to enter  into this
          Agreement  and to pledge and assign the  Collateral  to the Pledgee in
          accordance with the terms of this Agreement.

     (h)  Subject to the Pledgors' disclosures on Schedule 4.9 of the Securities
          Purchase  Agreement  Pledgor  owns  each item of the  Collateral  and,
          except  for the  pledge  and  security  interest  granted  to  Pledgee
          hereunder,  the Collateral shall be, immediately following the closing
          of the transactions  contemplated by the Documents,  free and clear of
          any  other   security   interest,   pledge,   claim,   lien,   charge,
          hypothecation,    assignment,   offset   or   encumbrance   whatsoever
          (collectively, "Liens").

                                      -3-
<PAGE>

     (i)  there are no  restrictions  on transfer of the Pledged Stock contained
          in  the  certificate  of   incorporation  or  by-laws  (or  equivalent
          organizational  documents)  of the Issuer or otherwise  which have not
          otherwise  been  enforceably  and  legally  waived  by  the  necessary
          parties.

     (j)  none of the Pledged Stock has been issued or  transferred in violation
          of the securities registration,  securities disclosure or similar laws
          of any jurisdiction to which such issuance or transfer may be subject.

     (k)  the  pledge  and  assignment  of the  Collateral  and the  grant  of a
          security  interest under this Agreement vest in the Pledgee all rights
          of Pledgor in the Collateral as contemplated by this Agreement.

     (l)  The Pledged Stock constitutes one hundred percent (100%) of the issued
          and outstanding shares of capital stock of each Issuer.

         5. Covenants.  Pledgor covenants that, until the Indebtedness  shall be
satisfied in full and each Document and each  agreement and  instrument  entered
into in connection therewith is irrevocably terminated:

     (a)  Pledgor will not sell, assign, transfer,  convey, or otherwise dispose
          of its rights in or to the  Collateral  or any interest  therein;  nor
          will any Pledgor create,  incur or permit to exist any Lien whatsoever
          with respect to any of the  Collateral  or the proceeds  thereof other
          than that created hereby.

     (b)  Pledgor  will,  at its  expense,  defend  Pledgee's  right,  title and
          security  interest in and to the Collateral  against the claims of any
          other party.

     (c)  Pledgor  shall at any time,  and from time to time,  upon the  written
          request of Pledgee,  execute and deliver such further documents and do
          such  further  acts and things as Pledgee  may  reasonably  request in
          order to effect the purposes of this Agreement including,  but without
          limitation,  delivering to Pledgee upon the  occurrence of an Event of
          Default  irrevocable  proxies  in respect  of the  Collateral  in form
          satisfactory  to  Pledgee.  Until  receipt  thereof,  upon an Event of
          Default  that has  occurred and is  continuing  beyond any  applicable
          grace period,  this  Agreement  shall  constitute  Pledgor's  proxy to
          Pledgee  or  its  nominee  to  vote  all  shares  of  Collateral  then
          registered in each Pledgor's name.

     (d)  No  Pledgor  will  consent  to or  approve  the  issuance  of (i)  any
          additional  shares  of any  class of  capital  stock  or other  equity
          interests of the Issuer;  or (ii) any  securities  convertible  either
          voluntarily by the holder thereof or automatically upon the occurrence
          or  nonoccurrence  of any event or condition  into, or any  securities
          exchangeable for, any such shares, unless, in either case, such shares
          are pledged as Collateral pursuant to this Agreement.

         6. Voting Rights and Dividends.

                                      -4-
<PAGE>

     (a)  Prior to an Event of Default  (and the  expiration  of any  applicable
          cure period pertaining  thereto) Pledgor shall (i) be entitled to vote
          the  Collateral,  (ii) be  entitled  to  give  consents,  waivers  and
          ratification  in respect of the  Collateral,  and (iii) be entitled to
          collect and receive for its own use cash  dividends  legally  declared
          available for distribution, on the Collateral.

     (b)  In addition to the Pledgee's  rights and remedies set forth in Section
          8 hereof,  in case an Event of  Default  shall  have  occurred  and be
          continuing,  beyond any applicable cure period,  the Pledgee shall (i)
          be entitled to vote the Collateral, (ii) be entitled to give consents,
          waivers and  ratifications  in respect of the Collateral (each Pledgor
          hereby irrevocably  constituting and appointing the Pledgee, with full
          power of substitution,  the proxy and attorney-in-fact of each Pledgor
          for such  purposes)  and (iii) be  entitled to collect and receive for
          its own use cash dividends paid on the Collateral. No Pledgor shall be
          permitted to exercise or refrain from  exercising any voting rights or
          other  powers if, in the  reasonable  judgment  of the  Pledgee,  such
          action  would  have a  material  adverse  effect  on the  value of the
          Collateral  or any part thereof;  and,  provided,  further,  that each
          Pledgor  shall  give at least  five (5)  days'  written  notice of the
          manner in which such Pledgor  intends to exercise,  or the reasons for
          refraining  from  exercising,  any voting rights or other powers other
          than with respect to any election of directors and voting with respect
          to any  incidental  matters.  Following the  occurrence of an Event of
          Default,  all dividends and all other  distributions in respect of any
          of the  Collateral,  shall  be  delivered  to the  Pledgee  to hold as
          Collateral and shall, if received by any Pledgor, be received in trust
          for the benefit of the Pledgee,  be segregated from the other property
          or funds of any  other  Pledgor,  and be  forthwith  delivered  to the
          Pledgee  as  Collateral  in the same  form as so  received  (with  any
          necessary endorsement).

         7.  Event of  Default.  An Event of  Default  shall be  deemed  to have
occurred  and may be declared by the Pledgee  upon the  happening  of any of the
following events:

     (a)  An "Event of  Default"  under any  Document or any  agreement  or note
          related to any Document  shall have occurred and be continuing  beyond
          any applicable cure period;

     (b)  Any  portion of the  Collateral  is  subjected  to levy of  execution,
          attachment, distraint or other judicial process; or any portion of the
          Collateral  is the subject of a claim (other than by the Pledgee) of a
          Lien or other right or interest in or to the  Collateral and such levy
          or claim  shall not be cured,  disputed  or stayed  within a period of
          forty four (44) days after the occurrence thereof; or


         8.  Remedies.  In case an Event of Default  shall have  occurred and be
declared by the Pledgee, the Pledgee may:

                                      -5-
<PAGE>

     (a)  Transfer any or all of the Collateral  into its name, or into the name
          of its nominee or nominees;

     (b)  Exercise  all  corporate   rights  with  respect  to  the   Collateral
          including,  without  limitation,  all rights of conversion,  exchange,
          subscription or any other rights,  privileges or options pertaining to
          any shares of the Collateral as if it were the absolute owner thereof,
          including,  but  without  limitation,  the right to  exchange,  at its
          discretion,   any  or  all  of  the   Collateral   upon  the   merger,
          consolidation, reorganization,  recapitalization or other readjustment
          of the  Issuer  thereof,  or upon the  exercise  by the  Issuer of any
          right,  privilege or option pertaining to any of the Collateral,  and,
          in  connection  therewith,  to deposit  and deliver any and all of the
          Collateral with any committee,  depository,  transfer agent, registrar
          or other  designated  agent upon such terms and  conditions  as it may
          determine,  all  without  liability  except to  account  for  property
          actually received by it; and

     (c)  Subject to any requirement of applicable law, sell, assign and deliver
          the whole or,  from time to time,  any part of the  Collateral  at the
          time held by the Pledgee,  at any private  sale or at public  auction,
          with or without demand,  advertisement  or notice of the time or place
          of sale or  adjournment  thereof or otherwise (all of which are hereby
          waived, except such notice as is required by applicable law and cannot
          be waived),  for cash or credit or for other property for immediate or
          future delivery, and for such price or prices and on such terms as the
          Pledgee in its sole discretion may determine, or as may be required by
          applicable law.

         Pledgor  hereby  waives  and  releases  any and all  right or equity of
redemption,  whether before or after sale  hereunder.  At any such sale,  unless
prohibited by applicable  law, the Pledgee may bid for and purchase the whole or
any  part of the  Collateral  so sold  free  from any such  right or  equity  of
redemption.  All moneys received by the Pledgee  hereunder  whether upon sale of
the Collateral or any part thereof or otherwise shall be held by the Pledgee and
applied by it as provided in Section 10 hereof.  No failure or delay on the part
of the Pledgee in exercising any rights  hereunder  shall operate as a waiver of
any such  rights  nor shall any single or partial  exercise  of any such  rights
preclude  any other or future  exercise  thereof  or the  exercise  of any other
rights  hereunder.  The  Pledgee  shall  have no duty  as to the  collection  or
protection  of  the  Collateral  or  any  income  thereon  nor  any  duty  as to
preservation  of any  rights  pertaining  thereto,  except to apply the funds in
accordance with the requirements of Section 10 hereof.  The Pledgee may exercise
its rights  with  respect to property  held  hereunder  without  resort to other
security for or sources of reimbursement  for the  Indebtedness.  In addition to
the foregoing,  Pledgee shall have all of the rights, remedies and privileges of
a secured party under the Uniform  Commercial Code of New York regardless of the
jurisdiction in which enforcement hereof is sought.


         9. Private Sale.  Pledgor  recognizes that the Pledgee may be unable to
effect (or to do so only after delay which would adversely affect the value that
might be  realized  from  the  Collateral)  a public  sale of all or part of the
Collateral by reason of certain  prohibitions  contained in the Securities  Act,
and may be  compelled  to resort to one or more  private  sales to a  restricted
group of purchasers who will be obliged to agree, among other things, to acquire
such Collateral for their own account, for investment and not with a view to the

                                      -6-
<PAGE>

distribution or resale thereof. Pledgor agrees that any such private sale may be
at prices and on terms less favorable to the seller than if sold at public sales
and that such private sales shall be deemed to have been made in a  commercially
reasonable  manner.  Pledgor  agrees that the Pledgee has no obligation to delay
sale of any  Collateral for the period of time necessary to permit the Issuer to
register the Collateral for public sale under the Securities Act.

         10.  Proceeds  of  Sale.  The  proceeds  of any  collection,  recovery,
receipt,  appropriation,  realization or sale of the Collateral shall be applied
by the Pledgee as follows:

     (a)  First, to the payment of all costs, reasonable expenses and charges of
          the  Pledgee  and to the  reimbursement  of the  Pledgee for the prior
          payment of such costs,  reasonable  expenses  and charges  incurred in
          connection with the care and safekeeping of the Collateral (including,
          without  limitation,  the reasonable expenses of any sale or any other
          disposition  of any of the  Collateral),  the  expenses of any taking,
          attorneys' fees and reasonable  expenses,  court costs, any other fees
          or expenses  incurred or  expenditures  or advances made by Pledgee in
          the  protection,  enforcement  or exercise  of its  rights,  powers or
          remedies hereunder;

     (b)  Second,  to the payment of the  Indebtedness,  in whole or in part, in
          such order as the Pledgee may elect,  whether or not such Indebtedness
          is then due;

     (c)  Third,  to such  persons,  firms,  corporations  or other  entities as
          required by applicable  law  including,  without  limitation,  Section
          9-504(1)(c) of the UCC; and

     (d)  Fourth,  to the extent of any  surplus to the Pledgor or as a court of
          competent jurisdiction may direct.

         In the event that the proceeds of any  collection,  recovery,  receipt,
appropriation, realization or sale are insufficient to satisfy the Indebtedness,
Pledgor  shall be  liable  for the  deficiency  plus the  costs  and fees of any
attorneys employed by Pledgee to collect such deficiency.

         11. Waiver of Marshaling. Pledgor hereby waives any right to compel any
marshaling of any of the Collateral.

         12. No Waiver.  Any and all of the Pledgee's rights with respect to the
Liens granted under this Agreement shall continue unimpaired,  and Pledgor shall
be and remain obligated in accordance with the terms hereof, notwithstanding (a)
the bankruptcy,  insolvency or reorganization of any Pledgor, (b) the release or
substitution  of any item of the  Collateral  at any time,  or of any  rights or
interests therein, or (c) any delay,  extension of time, renewal,  compromise or
other indulgence granted by the Pledgee in reference to any of the Indebtedness.
Each Pledgor  hereby  waives all notice of any such delay,  extension,  release,
substitution, renewal, compromise or other indulgence, and hereby consents to be
bound hereby as fully and  effectively  as if such Pledgor had expressly  agreed
thereto in advance.  No delay or extension of time by the Pledgee in  exercising
any power of sale, option or other right or remedy hereunder,  and no failure by
the Pledgee to give notice or make demand, shall constitute a waiver thereof, or
limit,  impair or prejudice the Pledgee's  right to take any action  against any
Pledgor or to  exercise  any other  power of sale,  option or any other right or
remedy.

                                      -7-

         13.  Expenses.  The Collateral  shall secure,  and Pledgor shall pay to
Pledgee  on  demand,  from time to time,  all  reasonable  costs  and  expenses,
(including but not limited to, reasonable  attorneys' fees and costs, taxes, and
all transfer,  recording,  filing and other  charges) of, or incidental  to, the
custody,  care,  transfer,   administration  of  the  Collateral  or  any  other
collateral,   or  in  any  way  relating  to  the  enforcement,   protection  or
preservation  of the rights or remedies of the Pledgee  under this  Agreement or
with respect to any of the Indebtedness.

         14. The  Pledgee  Appointed  Attorney-In-Fact  and  Performance  by the
Pledgee. Upon the occurrence of an Event of Default,  Pledgor hereby irrevocably
constitutes  and  appoints  the  Pledgee  as  such  Pledgor's  true  and  lawful
attorney-in-fact,  with full power of substitution,  to execute, acknowledge and
deliver any instruments and to do in such Pledgor's name,  place and stead,  all
such  acts,  things  and  deeds  for and on  behalf  of and in the  name of such
Pledgor,  which such  Pledgor  could or might do or which the  Pledgee  may deem
necessary, desirable or convenient to accomplish the purposes of this Agreement,
including,  without  limitation,  to execute such  instruments  of assignment or
transfer or orders and to register,  convey or otherwise  transfer  title to the
Collateral  into the Pledgee's  name.  Pledgor hereby  ratifies and confirms all
that said  attorney-in-fact may so do and hereby declares this power of attorney
to be coupled with an interest and irrevocable.  If Pledgor fails to perform any
agreement herein contained,  the Pledgee may itself perform or cause performance
thereof,  and any costs and  expenses  of the  Pledgee  incurred  in  connection
therewith shall be paid by the Pledgor as provided in Section 10 hereof.

         15. Waivers.

     (a)  EACH PARTY HERETO HEREBY  EXPRESSLY  WAIVES ANY RIGHT TO TRIAL BY JURY
          OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (A) ARISING UNDER THIS
          AGREEMENT OR ANY OTHER INSTRUMENT,  DOCUMENT OR AGREEMENT  EXECUTED OR

          NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR
          TORT OR  OTHERWISE  AND EACH PARTY HERETO  HEREBY  AGREES AND CONSENTS
          THAT ANY CLAIM, DEMAND,  ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY
          COURT  TRIAL  WITHOUT A JURY,  AND THAT ANY PARTY MAY FILE AN ORIGINAL
          COUNTERPART  OR A COPY OF THIS  SECTION  WITH  ANY  COURT  AS  WRITTEN
          EVIDENCE  OF THE  CONSENT  OF EACH PARTY TO THE WAIVER OF ITS RIGHT TO
          TRIAL BY JURY.

         16.  Recapture.  Notwithstanding  anything  to  the  contrary  in  this
Agreement,  if the  Pledgee  receives  any payment or payments on account of the
Indebtedness,  which  payment or payments or any part  thereof are  subsequently
invalidated,  declared  to be  fraudulent  or  preferential,  set  aside  and/or
required  to be repaid to a  trustee,  receiver,  or any other  party  under the

          law, such provision shall be deemed  inoperative to the extent that it
          may conflict therewith and shall be deemed modified to conform to such

          shall constitute one and the same agreement.  Any signature  delivered
