            3.6. SEC REPORTS AND FILINGS. The Company has delivered to Purchaser
a complete and accurate copy (excluding copies of exhibits) of its Annual Report

did not at and as of the time they were filed (or, if amended or superseded by a
filing  prior to the date of this  Agreement,  then on the date of such  filing)

required  to be stated  therein  or  necessary  in order to make the  statements
therein,  in  light  of the  circumstances  under  which  they  were  made,  not
misleading.

            3.8.  TITLE TO PROPERTIES  AND ASSETS;  LIENS,  ETC. The Company has
good and marketable title to its properties and assets, including the properties
and assets  reflected  in the most  recent  balance  sheet  included  in the SEC
Documents,  and good title to its leasehold estates,  in each case subject to no
mortgage,  pledge,  lien,  lease,  encumbrance  or charge,  other than (a) those

encumbrances  which do not  materially  detract  from the value of the  property

those  that have  otherwise  arisen in the  ordinary  course  of  business.  All
facilities, machinery, equipment, fixtures, vehicles and other properties owned,

Company is in compliance  with all material terms of each lease to which it is a
party or is otherwise bound.

            3.9.  COMPLIANCE  WITH  OTHER  INSTRUMENTS.  The  Company  is not in
violation or default of any term of its Certificate of  Incorporation or Bylaws,
or of any provision of any mortgage, indenture, contract, agreement,  instrument
or  contract  to which  it is party or by which it is bound or of any  judgment,
decree,  order,  writ or, to its  knowledge,  any  statute,  rule or  regulation
applicable  to the  Company  which would  materially  and  adversely  affect the
business, assets, liabilities, financial condition or operations of the Company.
The execution,  delivery, and performance of and compliance with this Agreement,
the Notes and the Warrants, and the issuance and sale of the Securities pursuant
hereto and of the Warrant Shares,  will not, with or without the passage of time
or giving of notice,  result in any such material  violation,  or be in conflict
with or  constitute a default  under any such term, or result in the creation of
any mortgage,  pledge, lien, encumbrance or charge upon any of the properties or
assets of the Company or the suspension,  revocation,  impairment, forfeiture or
nonrenewal of any permit license,  authorization  or approval  applicable to the
Company, its business or operations or any of its assets or properties.

            3.10.   LITIGATION.   There  is  no  action,  suit,   proceeding  or
investigation  pending or to the  Company's  knowledge  currently  threatened in
writing against the Company that questions the validity of this Agreement or the
Warrants or the right of the Company to enter into any of such agreements, or to
consummate  the  transactions  contemplated  hereby or  thereby,  or which might
result, either individually or in the aggregate,  in any material adverse change
in the assets, condition or affairs of the Company, financially or otherwise, or
any change in the current  equity  ownership of the Company,  nor is the Company
aware that there is any basis for the foregoing.  Notwithstanding the foregoing,
in April 2004,  the Company filed a demand for  arbitration  against  Eclipse by
Fujitsu Ten for  numerous  breaches  of the  contract  signed by Eclipse.  These
breaches include  cancellation of the initial  non-cancelable  order,  breach of
implied  covenant of good faith and fair dealing,  and  misappropriation  of our
intellectual property,  confidential,  proprietary and trade secret information.
As of the date hereof, the arbitration remains pending.

            3.11. EMPLOYEES. The Company has no collective bargaining agreements
with any of its employees.  There is no labor union organizing  activity pending
or, to the Company's knowledge, threatened with respect to the Company.

            3.12.  COMPLIANCE WITH LAWS; PERMITS. To its knowledge,  the Company
is not in  violation  of any  applicable  statute,  rule,  regulation,  order or
restriction  of any domestic or foreign  government  or any  instrumentality  or
agency thereof in respect of the conduct of its business or the ownership of its
properties  which violation would  materially and adversely affect the business,
assets,  liabilities,  financial  condition or  operations  of the  Company.  No
governmental  orders,  permissions,  consents,  approvals or authorizations  are
required to be obtained and no  registrations or declarations are required to be
filed in connection  with the  execution and delivery of this  Agreement and the
issuance of the Securities or the Warrant  Shares,  except such as has been duly
and validly  obtained or filed, or with respect to any filings that must be made
after the  Closing,  as will be filed in a timely  manner.  The  Company has all
franchises,  permits,  licenses  and any  similar  authority  necessary  for the
conduct of its  business as now being  conducted  by it, the lack of which could
materially and adversely affect the business, properties, prospects or financial
condition  of the Company and  believes it can obtain,  without  undue burden or
expense,  any similar authority for the conduct of its business as planned to be
conducted.

      4. REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS.

the times Purchaser might propose.

                  4.2.2. ACQUISITION FOR OWN ACCOUNT. Purchaser is acquiring the
Securities  and the Warrant  Shares for  Purchaser's  own account for investment
only, and not with a view towards their distribution.

experience,  Purchaser  has  the  capacity  to  protect  its  own  interests  in
connection  with  the  transactions  contemplated  in this  Agreement.  Further,
Purchaser  is aware of no  publication  of any  advertisement  or other  general
solicitation in connection with the transactions contemplated in the Agreement.

                  4.2.4. ACCREDITED INVESTOR. Purchaser represents that it is an
accredited  investor  within the meaning of Section 501(a) of the Securities Act

conditions of this investment.

                  4.2.6.  RULE 144.  Purchaser  acknowledges and agrees that the
Securities,  and, if issued, the Warrant Shares must be held indefinitely unless
they are  subsequently  registered under the Securities Act or an exemption from
such  registration  is available.  Purchaser has been advised or is aware of the
provisions of Rule 144  promulgated  under the  Securities Act as in effect from
time to time,  which  permits  limited  resale of shares  purchased in a private
placement subject to the satisfaction of certain  conditions,  including,  among
other things:  the availability of certain current public  information about the
Company,  the resale occurring  following the required holding period under Rule
144 and the  number of shares  being  sold  during  any  three-month  period not

                  6.1.1.  If, at any time from  issuance  to June 30,  2007 (the
"EXERCISE  PERIOD"),  the Company  proposes to prepare and file any registration
statements  covering its Common Stock (in either case,  other than in connection
with a merger or  acquisition,  pursuant to Form S-8 or any  successor  form, or
pursuant  to any  other  form or  type  of  registration  in  which  Registrable
Securities (as defined below) cannot be appropriately  included)  (collectively,
the "Registration  Statements"),  it will give written notice as provided herein
at  least  thirty  (30)  days  prior to the  filing  of each  such  Registration
Statement to the then holders of the Warrants  ("HOLDER")  and/or Warrant Shares
of its intention to do so. If the Holders of the Warrants  and/or Warrant Shares
notify the Company  within  twenty (20) days after receipt of any such notice of
its or their desire to include the shares of Common Stock issuable upon exercise
of  the  Warrant  or  the  Warrant  Shares   (collectively,   the   "REGISTRABLE
SECURITIES") in such proposed registration  statement,  the Company shall afford
the Holders of the Warrant  and/or  Warrant  Shares the  opportunity to have any
such Registrable  Securities registered under such registration statement at the
Company's sole cost and expense.

                  6.1.2.  Notwithstanding  the  provisions  hereof,  the Company
shall  have the  right at any time  after it shall  have  given  written  notice
pursuant hereto  (irrespective of whether a written request for inclusion of any
such  securities  shall have been  made) to elect not to file any such  proposed
registration  statement,  or to withdraw  the same after the filing but prior to
the effective date thereof.

                  6.1.3.  Notwithstanding any other provision of this Section 6,
if the underwriter  managing such  registration  notifies the Holders in writing
that  market or economic  conditions  limit the amount of  securities  which may
reasonably be expected to be sold,  the Holders of such  Registrable  Securities
will be allowed to register their  Registrable  Securities pro rata based on the
number of shares of Registrable  Securities held by such Holders,  respectively.
No  Registrable  Securities  excluded  from the  underwriting  by  reason of the
underwriter's marketing limitation shall be included in such registration.

                  6.1.4.  Each Holder of Warrants and Warrant  Shares to be sold
pursuant to any  Registration  Statement  (each, a "DISTRIBUTING  HOLDER") shall
severally,  and not  jointly,  indemnify  and hold  harmless  the  Company,  its
officers and directors,  each underwriter and each person,  if any, who controls
the Company and such underwriter,  against any loss, claim,  damage,  expense or
liability,  joint or  several,  as  incurred,  to which  any of them may  become
subject  under the  Securities  Act or any other statute or at common law, in so
far as such loss,  claim,  damage,  expense or liability  (or actions in respect
thereof)  arises out of or is based upon any untrue  statement or alleged untrue
statement of any material fact contained in any such Registration Statement, any
preliminary  prospectus or final prospectus  contained therein, or any amendment
or supplement  thereto,  or any omission or alleged  omission to state therein a
material fact required to be stated  therein or necessary to make the statements
therein,  in  light  of the  circumstances  under  which  they  were  made,  not
misleading, in each case to the extent, but only to the extent, that such untrue
statement or alleged untrue  statement or omission or alleged  omission was made
in reliance upon and in  conformity  with written  information  furnished to the
Company  by  such  Distributing  Holder  specifically  for  use  therein.   Such
Distributing Holder shall reimburse the Company,  such underwriter and each such
officer,  director  or  controlling  person  for any  legal  or  other  expenses
reasonably incurred by any of them in connection with investigating or defending
any such liability, as incurred.  Notwithstanding the foregoing,  such indemnity
with respect to such  preliminary  prospectus or such final prospectus shall not
inure  to the  benefit  of the  Company,  its  officers  or  directors,  or such
underwriter (or such  controlling  person of the Company or the  underwriter) if
the  person  asserting  any such  loss,  claim,  damage,  expense  or  liability
purchased the securities that are the subject thereof and did not receive a copy
of the final  prospectus  (or the final  prospectus as then amended,  revised or
supplemented)  at or  prior to the  time  such  furnishing  is  required  by the
Securities  Act in any case where any such  untrue  statement  or  omission of a
material fact contained in the preliminary prospectus was corrected in the final
prospectus (or, if contained in the final prospectus, was subsequently corrected
by amendment, revision or supplement).

            6.2.  PUBLIC  OFFERING  LOCK-UP.   In  connection  with  any  public
registration  of this  Company's  securities,  the Holder (and any transferee of
Holder) agrees,  upon the request of the Company or the underwriter(s)  managing
such offering of the Company's securities,  not to sell, make any short sale of,
loan,  grant any  option  for the  purchase  of, or  otherwise  dispose  of this
Warrant,  any of the  shares of Common  Stock  issuable  upon  exercise  of this
Warrant   without   the  prior   written   consent  of  the   Company  and  such
underwriter(s),  as the case  may be,  for a period  of time  not to  exceed  on
hundred  eighty (180) days from the  effective  date of the  registration.  Upon
request by the Company,  Holder (and any  transferee of Holder)  agrees to enter
into any further  agreement in writing in a form reasonably  satisfactory to the
Company  and/or  such  underwriter(s).  The  Company  may  impose  stop-transfer
instructions   with  respect  to  the   securities   subject  to  the  foregoing
restrictions  until the end of said  180-day  period.  Any  shares  issued  upon
exercise of this  Warrant  shall bear an  appropriate  legend  referencing  this
lock-up provision.

      7. INTERCREDITOR AGREEMENT

      Each Note issued to a Purchaser is one of a duly authorized issue of Notes
of the Company  designated as its 12%  Subordinated  Promissory Notes limited in
aggregate principal amount to $1,000,000.  Each Purchaser understands and agrees
that a default is not an Event of  Default  (as  defined in the Note)  until the
holders  of at  least  25% in  aggregate  principal  amount  of the  Notes  then
outstanding  notify the Company of such default and the Company does not cure it
within  sixty (60) days after  receipt of such  notice,  which must  specify the
default,  demand that it be remedied and state that it is a "NOTICE OF DEFAULT."
If an Event of Default occurs and is continuing,  the Noteholder(s) by notice to
the Company,  may declare the principal of and accrued  interest on the Notes to
be due and payable immediately;  provided, however, that the holders of at least
51% in  aggregate  principal  amount of the Notes then  outstanding,  by written
notice  to  the  Company,  may  rescind  and  annul  such  declaration  and  its
consequences.

      The  Company  shall  only make  principal  reductions  pro rata  among the
Noteholders.  Likewise any Noteholder who receives any payments or proceeds from
any enforcement of a security  interest or any distribution in connection with a
bankruptcy,  liquidation,  reorganization,  dissolution,  winding-up  or similar
proceedings,  shall be  obligated  to pro rate  such  amounts  among  the  other
Noteholders of the series.

      8. MISCELLANEOUS.

by the laws of the State of  California  as such laws are applied to  agreements
between California residents entered into and performed entirely in California.

            8.2.  SURVIVAL.  The  representations,   warranties,  covenants  and
agreements made herein shall survive any investigation made by any Purchaser and
the  closing of the  transactions  contemplated  hereby.  All  statements  as to
factual matters contained in any certificate or other instrument delivered by or
on behalf of the Company  pursuant  hereto in connection  with the  transactions
contemplated  hereby shall be deemed to be representations and warranties by the
Company hereunder solely as of the date of such certificate or instrument.

            8.3. SUCCESSORS AND ASSIGNS.  Except as otherwise expressly provided
herein,  the  provisions  hereof  shall  inure to the benefit of, and be binding
upon,  the  successors,  assigns,  heirs,  executors and  administrators  of the
parties  hereto and shall  inure to the  benefit of and be  enforceable  by each
person who shall be a holder of the Securities from time to time.

            8.4. ENTIRE  AGREEMENT.  This Agreement,  the Note, the Exhibits and
Schedules hereto, the Warrants and the other documents delivered pursuant hereto
constitute the full and entire  understanding  and agreement between the parties
with regard to the subjects  hereof and no party shall be liable or bound to any
other in any manner by any representations, warranties, covenants and agreements
except as specifically set forth herein and therein.

            8.5.  SEVERABILITY.  In case any provision of the Agreement shall be
invalid, illegal or unenforceable,  the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

            8.6. AMENDMENT AND WAIVER.

                  8.6.1. This Agreement may be amended or modified only upon the
written consent of the Company and holders of at least  fifty-one  percent (51%)

                  8.6.2.  The  obligations  of the Company and the rights of the
holders of the Notes,  the Warrants and the Warrant  Shares under the  Agreement
may be waived only with the written consent of the holders of at least fifty-one
percent (51%) in the aggregate principal amount of the Notes outstanding.

            8.7. DELAYS OR OMISSIONS.  It is agreed that no delay or omission to
exercise  any right,  power or remedy  accruing  to any party,  upon any breach,
default or noncompliance by another party under this Agreement, shall impair any
such right,  power or remedy,  nor shall it be  construed  to be a waiver of any
such breach, default or noncompliance,  or any acquiescence therein, or of or in
any similar breach, default or noncompliance thereafter occurring. It is further
agreed that any waiver,  permit, consent or approval of any kind or character on
any  Purchaser's  part  of any  breach,  default  or  noncompliance  under  this
Agreement or any waiver on such party's part of any  provisions or conditions of
the  Agreement  must be in  writing  and shall be  effective  only to the extent
specifically  set  forth  in such  writing.  All  remedies,  either  under  this
Agreement,  or  otherwise  afforded to any party,  shall be  cumulative  and not
alternative.

            8.8. NOTICES.  All notices required or permitted  hereunder shall be

Company or Purchaser  may designate by ten (10) days advance  written  notice to
the other parties hereto.

            8.9.  EXPENSES.  Each party shall pay all costs and expenses that it
incurs with respect to the negotiation,  execution,  delivery and performance of
this Agreement,  the Notes and the Warrants.

            8.10.  ATTORNEYS'  FEES.  In the event  that any  dispute  among the
parties to this Agreement  should result in litigation,  the prevailing party in
such dispute shall be entitled to recover from the losing party all fees,  costs
and  expenses  of  enforcing  any right of such  prevailing  party under or with
respect to this Agreement,  including without  limitation,  such reasonable fees
and  expenses  of  attorneys  and  accountants,  which  shall  include,  without
limitation, all fees, costs and expenses of appeals.

            8.11.  TITLES  AND  SUBTITLES.   The  titles  of  the  sections  and
subsections  of the Agreement are for  convenience of reference only and are not
to be considered in construing this Agreement.

by the  Purchasers  through  June 30,  2004 in any  number of  counterparts,  by
facsimile,  or  both,  each of  which  shall  be an  original,  but all of which
together  shall  constitute  one  instrument.  Subsequent  sales  after  a first
Closing,  as  provided  in  Section  2.3,  shall be added to this  agreement  to
constitute one instrument binding on all parties thereto.

                                       8
<PAGE>

            8.13. BROKER'S FEES. No agent, broker,  investment banker, person or
firm acting on behalf of or under the  authority of such party hereto is or will
be entitled to any broker's or finder's fee or any other commission  directly or
indirectly in connection with the transactions  contemplated  herein. Each party
hereto further  agrees to indemnify  each other party for any claims,  losses or
expenses incurred by such other party as a result of the  representation in this

it is not relying upon any person, firm, or corporation,  other than the Company
and its officers and  directors,  in making its investment or decision to invest

NOTE SERIES 04-A

THIS NOTE HAS NOT BEEN  REGISTERED  UNDER THE UNITED  STATES  SECURITIES  ACT OF
1933,  AS AMENDED  (THE "ACT"),  OR UNDER ANY STATE  SECURITIES  LAWS,  AND IS A
"RESTRICTED  SECURITY"  AS THAT TERM IS DEFINED IN RULE 144 UNDER THE ACT.  THIS
NOTE MAY NOT BE  OFFERED,  SOLD,  TRANSFERRED,  PLEDGED OR  HYPOTHECATED  IN THE
ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR SUCH SECURITIES UNDER THE ACT
OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT AN EXEMPTION FROM SUCH
REGISTRATION IS AVAILABLE.

THIS NOTE IS SUBJECT  TO  CERTAIN  RESTRICTIONS  ON  TRANSFER  SET FORTH IN THAT
CERTAIN  12%  SUBORDINATED   PROMISSORY  NOTE  AND  WARRANT  PURCHASE  AGREEMENT
("PURCHASE  AGREEMENT")  THEREFOR  BETWEEN THE COMPANY AND THE  ORIGINAL  HOLDER
HEREOF.

                          (ALL AMOUNTS IN U.S. DOLLARS)

                              E.DIGITAL CORPORATION

                        12% SUBORDINATED PROMISSORY NOTE

               Note Date: _________________ US$_____________. 00

                             San Diego, California

      FOR  VALUE  RECEIVED,  e.Digital  Corporation,  the  undersigned  Delaware
corporation  (together with all successors,  the "COMPANY"),  hereby promises to
pay to the order of

         Payee:            _______________________________________
                           or his, her or its successors or assigns
                            (collectively, "NOTEHOLDER") at

         Address:

or at such other address or addresses as Noteholder may  subsequently  designate
in writing to the Company,  the  principal  sum of  ________________  and NO/100
Dollars ($______________.00), due and payable in one installment on July 1, 2005
("MATURITY  DATE"),  plus simple interest  thereon at the rate of twelve percent
(12.00%) per annum,  in lawful monies of the United States of America.  Interest
shall be paid in monthly  installments on or before the first day of each month,
computed on the basis of a 360 day year and a 30 day month. If the Maturity Date
should  fall on a  weekend  or  national  holiday,  payment  shall be due on the
following  business day. This Note is one of a duly authorized issue of Notes of
the Company  designated as its 12% Subordinated  Promissory Notes (herein called
the "NOTES"), limited in aggregate principal amount to $1,000,000.

      1. Any payment  shall be deemed  timely  made if  received  by  Noteholder
within  fifteen (15) calendar days of the due date.  Payments  received shall be
imputed  first to late or penalty  charges,  if any,  then due, next to interest
payments then due, and next to the remaining unpaid principal balance.

      An "EVENT OF DEFAULT"  occurs if (a) the Company does not make the payment
of interest or  principal of this Note when the same becomes due and payable and
such default shall  continue for a period of fifteen (15) calendar days, (b) the
Company  fails to comply with any of its other  agreements  in this Note that do
not otherwise have separate  remedies or provisions  and such failure  continues
for the period and after the notice  specified  below, (c) pursuant to or within
the meaning of any Bankruptcy Law (as  hereinafter  defined),  the Company:  (i)
commences a voluntary  case;  (ii)  consents to the entry of an order for relief
against it in an  involuntary  case;  (iii)  consents  to the  appointment  of a
Custodian (as hereinafter  defined) of it or for all or substantially all of its
property or (iv) makes a general  assignment for the benefit of its creditors or
(v) a court of  competent  jurisdiction  enters  an order or  decree  under  any
Bankruptcy  Law that:  (A) is for relief  against the Company in an  involuntary
case; (B) appoints a Custodian of the Company or for all or substantially all of
its  property or (C) orders the  liquidation  of the  Company,  and any order or
decree  remains  unstayed and in effect for a period of sixty (60) days. As used
herein,  the term  "BANKRUPTCY  LAW" means Title 11 of the United States Code or
any similar federal or state law for the relief of debtors. The term "CUSTODIAN"
means any receiver, trustee, assignee,  liquidator or similar official under any
Bankruptcy Law.

<PAGE>

         A default above is not an Event of Default until the holders of at
least 25% in aggregate principal amount of the Notes then outstanding notify the
Company of such default and the Company does not cure it within sixty (60) days
after receipt of such notice, which must specify the default, demand that it be
remedied and state that it is a "NOTICE OF DEFAULT." If an Event of Default
occurs and is continuing, the Noteholder hereof by notice to the Company, may
declare the principal of and accrued interest on this Note to be due and payable
immediately; provided, however, that the holders of at least 51% in aggregate
principal amount of the Notes then outstanding, by written notice to the
Company, may rescind and annul such declaration and its consequences.

      2. The Company may prepay this Note at any time and from time to time,  in
whole or in part,  without  the prior  written  agreement  of  Noteholder,  upon
payment of a prepayment  fee equal to thirty  days'  interest (on the portion of
principal that is being  prepaid).  Any prepayment of this Note shall be applied
first against any prepayment fee, then against accrued interest and then against
principal.  Upon  payment  in full of the  principal  amount  of this  Note  and
interest thereon, the Noteholder shall surrender this Note for cancellation. The
Company shall only make principal  reductions or prepayments  pro rata among the
Noteholders of this series. Likewise any Noteholder who receives any payments or
proceeds from any  enforcement  of a security  interest or any  distribution  in
connection  with  a  bankruptcy,   liquidation,   reorganization,   dissolution,
winding-up or similar  proceedings,  shall be obligated to pro rate such amounts
among the other Noteholders of this series as provided in the Purchase Agreement
between the Company and the original holder hereof.

      3. Relationships  between the Noteholder and each of the other Noteholders
shall be  determined  pursuant  to the  intercreditor  agreements  set  forth in
Section 7 of the 12% Subordinated Promissory Note and Warrant Purchase Agreement
of even date (the  "PURCHASE  AGREEMENT")  and Sections 1 and 2 herein on a pari
passu basis.

      4. This Note is being  issued in  conjunction  with  certain  warrants.  A
portion of the original issue price of this investment unit  (consisting of this
Note and its  associated  warrants) has been  allocated to these  warrants.  The
original issue price of this Note is therefore  less than its principal  amount.
Because the excess of the principal  amount of this Note over its original issue
price is less than (a)  one-quarter  of one  percent  of this  Note's  principal
amount (b) multiplied by the number of complete  years to this Note's  maturity,
this Note will not have "ORIGINAL  ISSUE DISCOUNT" as that phrase is defined for
United  States  income tax purposes.  Any  Noteholder  may contact the Company's
Chief Financial Officer,  Treasurer or Chief Accounting Officer at its principal
office (or such other address as the Company shall  subsequently  furnish to the
Noteholder) for further information concerning the computation of original issue
discount under the terms of this Note.

      5. In the event that the Company  shall offer shares of its capital  stock
("CAPITAL STOCK") (or securities convertible into shares of Capital Stock) on or
after  the  date  hereof  in  connection  with  an  equity  financing   ("EQUITY
FINANCING"),  the Noteholder shall have the right and option,  at any time prior
to the Maturity Date,  subject to and upon compliance with the provisions hereof
and the  terms and  provisions  of the  Equity  Offering  documents  (including,
without limitation, strict adherence to the closing dates set forth therein), to
convert the unpaid principal amount of the Note, the prepayment fee, if any, and
any accrued and unpaid  interest  (on an "ALL OR NONE BASIS") into shares of the
Capital Stock being offered.  The conversion price ("CONVERSION PRICE") shall be
equal to the offering  price (as defined in the Equity  Financing  documents) of
the capital stock in effect at the time of conversion.. In order to exercise the
conversion privilege,  the Noteholder shall surrender the Note to the Company at
its principal  office duly endorsed or  accompanied  by a written  instrument of
transfer duly executed by the  Noteholder,  accompanied by written notice to the
Company  stating that the  Noteholder  elects to convert the Note subject to the
provisions  hereof setting forth the name(s) in which the certificate for shares
of Capital Stock issuable upon such conversion  shall be issued.  As promptly as
practicable  after the  receipt  of such  notice and the  surrender  of the Note
aforesaid,  the Company shall issue and deliver to such holder a certificate for

                                       2

the number of full shares of Capital Stock issuable upon such  conversion.  Such
conversion shall be deemed to be effected at the time at which such notice shall
have been  received  by the  Company  and the Note shall  have been  surrendered
aforesaid,  and the person in whose name any  certificate  for shares of Capital
Stock shall be issuable upon such  conversion  shall be deemed to become on said
date the holder of record of the shares represented  thereby.  The Company shall
not be required to issue fractions of shares of Capital Stock upon conversion of
the Note. If any fractional interest in a share of Capital Stock would otherwise
be  deliverable  upon  conversion,  the Company shall  purchase such  fractional
interest  for an amount in cash  equal to the  Conversion  Price then in effect,
calculated to the nearest cent. Noteholder expressly  acknowledges that the sale
or  issuance  of  Capital  Stock  by  the  Company  pursuant  to  (i)  presently
outstanding  convertible  securities,  (ii) employee benefit plans,  (iii) stock
option  plans,   (iv)  mergers  or  acquisitions  and/  or  (v)  other  non-cash
transactions  shall not constitute an Equity  Financing for purposes  hereof and
shall not result in any conversion  right  hereunder.  Noteholder also expressly
acknowledges  that  the  Capital  Stock  that may be  issued  upon  exercise  of
Noteholder's conversion rights hereunder may bear a legend substantially similar
to the  legend  set forth on the Note  and/or  such  other  legend(s)  as may be
required pursuant to the terms of the Equity Financing.

      6.  The   indebtedness   evidenced  by  this  Note  is  hereby   expressly
subordinated, to the extent and in the manner hereinafter set forth, in right of
payment  to  the  prior  payment  in  full  of  all  of  the  Company's   Senior
Indebtedness,  as  hereinafter  defined;  provided,  however,  that the  maximum
aggregate amount of the Company's Senior  Indebtedness to which the indebtedness
evidenced  by this Note  shall be  subordinated  shall not  exceed  One  Million
Dollars  ($1,000,000).  The  Company  may,  however,  in its sole  and  absolute
discretion,  incur and/or have outstanding from time to time Senior Indebtedness
in excess of the amount stated in the immediately  preceding  sentence,  and the
existence  of  such  Senior  Indebtedness  shall  not  diminish  in any  way the
subordination of the indebtedness evidenced by this Note.

      As used in this  Note,  the  term  "SENIOR  INDEBTEDNESS"  shall  mean the
principal of and unpaid accrued interest on: (a) all indebtedness of the Company
to banks,  insurance companies or other financial institutions regularly engaged
in the  business of lending  money,  which is for money  borrowed by the Company
(whether or not secured and whether or not  existing as of the date of this Note
or hereafter  incurred);  (b) the 15% Unsecured  Promissory Note in the original
principal  amount of $750,000  issued by the Company on December  11,  2002,  as
amended (the "15%  UNSECURED  NOTE");  and (c) any such  indebtedness  issued in
exchange  for such Senior  Indebtedness,  or any  indebtedness  arising from the
satisfaction of such Senior Indebtedness by a guarantor.

      If there should occur any  receivership,  insolvency,  assignment  for the
benefit of creditors,  bankruptcy,  reorganization or arrangement with creditors
(whether or not pursuant to bankruptcy or other insolvency laws), sale of all or
substantially  all  of  the  assets,  dissolution,   liquidation  or  any  other
marshalling of the assets and liabilities of the Company,  or if this Note shall
be declared  due and payable  upon the  occurrence  of an event of default  with
respect  to any  Senior  Indebtedness,  then (a) no amount  shall be paid by the
Company in  respect of the  principal  of or  interest  on this Note at the time
outstanding,  unless  and  until  the  principal  and  interest  on  the  Senior
Indebtedness  then outstanding  shall be paid in full; and (b) no claim or proof
of claim shall be filed with the Company by or on behalf of the Noteholder  that
shall  assert any right to receive any  payments in respect of the  principal of
and  interest  on  this  Note,  except  subject  to the  payment  in full of the
principal of and interest on all of the Senior Indebtedness then outstanding. If
there occurs an event of default that has been  declared in writing with respect
to any  Senior  Indebtedness,  or in  the  instrument  under  which  any  Senior
Indebtedness is outstanding,  permitting the holder of such Senior  Indebtedness
to accelerate the maturity thereof, then, unless and until such event of default
shall have been cured and  waived or shall have  ceased to exist,  or all Senior
Indebtedness  shall have been paid in full,  no payment shall be made in respect
of the  principal  of or interest on this Note,  unless  within three (3) months
after the  happening  of such event of  default,  the  maturity  of such  Senior
Indebtedness shall not have been accelerated.

      Subject to the rights, if any, of the holders of Senior Indebtedness under
this  Section 6 to  receive  cash,  securities  and other  properties  otherwise
payable or deliverable to the  Noteholder,  nothing  contained in this Section 6
shall impair,  as between the Company and the Noteholder,  the obligation of the
Company,  subject to the terms and conditions  hereof,  to pay to the Noteholder
the  principal  hereof and  interest  hereon as and when the same become due and
payable,  or  shall  prevent  the  Noteholder,   upon  default  hereunder,  from
exercising  all rights,  powers and  remedies  otherwise  provided  herein or by
applicable law.

      Subject to the payment in full of all Senior  Indebtedness  and until this
Note shall be paid in full, the Noteholder  shall be subrogated to the rights of
the holders of Senior  Indebtedness  (to the extent of payments or distributions
previously  made  to  such  holders  of  Senior  Indebtedness  pursuant  to  the
provisions of this Section 6) to receive  payments or distributions of assets of
the  Company  applicable  to  the  Senior  Indebtedness.  No  such  payments  or
distributions  applicable  to the Senior  Indebtedness  shall,  as  between  the
Company and its creditors, other than the holders of Senior Indebtedness and the
Noteholder,  be deemed to be a payment  by the  Company to or on account of this
Note; and for the purposes of such subrogation,  no payments or distributions to
the holders of Senior  Indebtedness  to which the  Noteholder  would be entitled
except for the  provisions  of this Section 6 shall,  as between the Company and
its creditors, other than the holders of Senior Indebtedness and the Noteholder,
be  deemed  to be a  payment  by the  Company  to or on  account  of the  Senior
Indebtedness.

      By its  acceptance  of this Note,  the  Noteholder  agrees to execute  and
deliver such  documents as may be requested  from time to time by the Company or
the  lender of any  Senior  Indebtedness  in order to  implement  the  foregoing
provisions of this Section 6.

      7.  If  this  Note  becomes  worn,  defaced  or  mutilated  but  is  still
substantially intact and recognizable,  the Company or its agent may issue a new
Note in lieu hereof upon its  surrender.  Where the  Noteholder  claims that the
Note has been lost, destroyed or wrongfully taken, the Company shall issue a new
Note of like tenor in place of the original  Note if the  Noteholder so requests
by written  notice to the Company  together with an affidavit of the  Noteholder
setting forth the facts concerning such loss, destruction or wrongful taking and
such  other  information  in such form with such  proof or  verification  as the
Company  may  request.  The  Company  in  addition  may  require,  at  its  sole
discretion,  indemnification  and/or an indemnity bond in such amount and issued
by such surety as the Company deems satisfactory.

      8. If the  indebtedness  represented  by this Note or any part  thereof is
collected in bankruptcy,  receivership or other judicial  proceedings or if this
Note is placed in the hands of  attorneys  for  collection  after  default,  the
Company  agrees to pay,  in  addition  to the  principal  and  interest  payable
hereunder, reasonable attorneys' fees and costs incurred by the Noteholder.

      9. Any notice, demand,  consent or other communication  hereunder shall be
in writing  addressed to the Company at its principal  office or, in the case of
Noteholder, at Noteholder's address appearing above, or to such other address as
such party shall have  theretofore  furnished by like notice,  and either served
personally,  sent by express,  registered or certified first class mail, postage
prepaid,  sent by facsimile  transmission,  or delivered by reputable commercial
courier. Such notice shall be deemed given (a) when so personally delivered,  or
(b) if mailed as aforesaid, five (5) days after the same shall have been posted,
or (c) if sent by facsimile transmission, as soon as the sender receives written
or telephonic confirmation that the message has been received and such facsimile
is  followed  the same day by mailing by prepaid  first  class  mail,  or (d) if
delivered by commercial courier, upon receipt.

      10. The Company hereby waives present,  demand for performance,  notice of
non-performance,  protest, notice of protest and notice of dishonor. No delay on
the part of  Noteholder  in exercising  any right  hereunder  shall operate as a
waiver of such right or any other right.

      11. This Note shall be governed by and  construed in  accordance  with the
laws of the State of  California  applicable to contracts  between  residents of
such state entered into and to be performed entirely within such state.

      12. Each  provision of this Note shall be interpreted in such manner as to
be effective and valid under  applicable  law, but if any provision of this Note
is held to be  prohibited  by or invalid under  applicable  law, such  provision
shall be  ineffective  only to the  extent of such  prohibition  or  invalidity,
without invalidating the remainder of this Agreement.

      IN WITNESS WHEREOF, the undersigned Company has executed this Note and has
affixed hereto its corporate seal.
