                          REGISTRATION RIGHTS AGREEMENT

      Registration  Rights  Agreement,  dated  as of  February  12,  2004  (this
"AGREEMENT"),  by and among Auto Data Network, Inc., a Delaware corporation (the
"COMPANY"), and the Purchasers (as defined below).

                              W I T N E S S E T H :

      WHEREAS, the Company is offering (the "OFFERING") an aggregate of up to 3,
947,368 shares (subject to increase by exercise of an overallotment option to an
aggregate of up to 4,342,105 shares,  and to further increase to an aggregate of
up to 5,514,474 shares in the event of exercise of preemptive  rights by certain
holders of the Company's  securities) of its Series B Preferred Stock, par value
$.001 per share (the "SERIES B PREFERRED STOCK"), convertible into shares of the
Company's  Common Stock,  together with  Warrants (the  "WARRANTS")  to purchase
shares of the  Common  Stock  (the  securities  offered  in the  Offering  being
sometimes hereinafter referred to as the "SECURITIES");

      WHEREAS,  the Company  desires to issue and sell to the persons  listed on
Schedule  A,  attached  hereto  (each  a  "PURCHASER,"  and  collectively,   the
"PURCHASERS"),  the Securities as set forth in one or more  Securities  Purchase
Agreements  entered  into or to be entered  into by and  between the Company and
each Purchaser (the "SECURITIES PURCHASE AGREEMENT");

      WHEREAS,  the Company and the Purchasers have entered or will have entered
into a Securities Purchase Agreement;

      WHEREAS,   it  is  a  condition  precedent  to  the  consummation  of  the
transactions  contemplated by the Securities Purchase Agreement that the Company
provide for the rights set forth in this Agreement; and

      WHEREAS,  certain  terms used in this  Agreement  are defined in Section 3
hereof.

      NOW, THEREFORE,  in consideration of the foregoing premises and the mutual
covenants and agreements hereinafter contained,  and for other good and valuable
consideration,  the receipt and  sufficiency  of which are hereby  acknowledged,
intending to be legally bound, the parties hereto hereby agree as follows:

      1. Registration Rights.

1.1 Required Registration.  The Company shall use its reasonable best efforts to
prepare  and file with the SEC within  ninety  (90) days  following  the Initial
Closing Date (as such term is defined in the Securities  Purchase  Agreement) or
the termination of the Offering, if no final Closing (as such term is defined in
the Securities  Purchase  Agreement) is held, as the case may be, a registration
statement on Form SB-1 or successor form or another form selected by the Company
that is  available  to it under  the  Securities  Act  which  conforms  with all
applicable  rules and regulations (the "REQUIRED  REGISTRATION  STATEMENT") with
respect to all the

<PAGE>

Registrable Securities  beneficially owned by the Purchasers following the final
Closing (as such term is defined in the Securities Purchase Agreement) to permit
the  offer  and  re-sale  from time to time of such  Registrable  Securities  in
accordance  with the methods of  distribution  provided by the  Purchasers.  The
Company shall use its reasonable best efforts to cause the Required Registration
Statement to become effective as promptly as reasonably practicable  thereafter,
and in any  event no later  than  June  30,  2004.  The  Company  shall  use its
reasonable   best  efforts  to  keep  such   Required   Registration   Statement
continuously  effective (the "EFFECTIVE  PERIOD") for a period of one year after
the Required Registration Statement first becomes effective plus whatever period
of time as shall equal any period,  if any, during such one year period in which
the Company was not current with its reporting  requirements  under the Exchange
Act. In the event that (X) the Company does not use its reasonable  best efforts
to file within the later to occur of (a) 90 days  following the Initial  Closing
Date  or (b) 45 days  following  the  final  Closing,  or (Y)  the  registration
statement is not declared effective within 120 days following the final Closing,
the Company shall incur a penalty for every subsequent 30 day period  thereafter
(but with no  doubling  of the  penalty  if both  conditions  are not met).  The
penalty for each such 30 day period shall  consist of  additional  Warrants (the
"PENALTY WARRANTS"),  on the same terms and conditions as the Warrants initially
issued in this  Offering.  The number of Penalty  Warrants to be issued for each
such 30 day period shall consist,  in the aggregate,  of that number of Warrants
as would entitle the holders of Shares, in the aggregate,  to purchase shares of
Common Stock equal to 2% of the Common Stock into which the Shares are initially
convertible (subject to adjustment for stock splits, reclassification of shares,
etc.).  The Penalty  Warrants  shall be payable to the holders of the Shares pro
rata in accordance with their  percentage  interest in the  outstanding  Shares.
Notwithstanding  the  foregoing,  in no event shall the Company be  obligated to
issue Penalty Warrants which, in the aggregate,  would equal or exceed either of
the following numbers of Penalty  Warrants:  (A) that number of Penalty Warrants
which would entitle the holders of Shares, in the aggregate,  to purchase shares
of Common Stock equal to more than 24% of the Common Stock into which the Shares
are   initially   convertible   (subject  to   adjustments   for  stock  splits,
reclassification  of shares,  etc.) or (B) that number of Penalty Warrants which
would  entitle  the  holders of Shares,  in the  aggregate,  to purchase so many
shares of Common Stock as to require  shareholder  approval for such issuance or
for the  Offering  as a  whole,  either  under  applicable  corporate  law,  the
Company's  certificate of incorporation or bylaws,  or the rules of any exchange
or other trading  market on which the Company's  securities are now or hereafter
traded.

            To the extent that the Registrable Securities are not sold under the
Required  Registration  Statement,  the Purchasers  shall have the  registration
rights as enumerated in Sections 1.2, 1.3 and 1.4.

            1.2 Demand Registrations.

            (a) Requests for Registration. Subject to Sections 1.2(b) and 1.2(e)
below,  the Purchasers  holding at least 33% of the Registrable  Securities (the
"INITIATING  HOLDERS")  may at any time after the  completion  of the  Effective
Period,  or if the Required  Registration  Statement has not been  effective for
more than ninety (90) days immediately preceding any request under

                                      -2-
<PAGE>

this Section  1.2(a),  request  registration  under the Securities Act of all or
part of their Registrable Securities on Form S-1, Form S-2, or, if available, on
Form S-3, or any successor  form of  registration;  provided that the Initiating
Holders  (together  with all  other  holders  of  Registrable  Securities  to be
included in such  registration)  propose to sell  Registrable  Securities to the
public of the  greater  of (i) an  aggregate  price  (calculated  based upon the
Market  Price  of the  Registrable  Securities  on the  date  of  filing  of the
Registration  Statement  with  respect to such  Registrable  Securities)  to the
public  of at least  $1,000,000,  or (ii) at least  25% of the then  outstanding
Registrable  Securities  or, if less than (i) or (ii),  then (iii) the remaining
Registrable Securities.  Each such registration request shall specify the number
of Registrable  Securities  requested to be registered and if the offering is to
be an  underwritten  offering.  Within ten (10) days  after  receipt of any such
request, the Company will give written notice of such requested  registration to
all other  holders of  Registrable  Securities  and,  subject to the  provisions
hereof,  will  include in such  registration  all  Registrable  Securities  with
respect to which the Company has received written requests for inclusion therein
within fifteen (15) days after the holder's  receipt of the Company's  notice. A
registration requested pursuant to this Section 1.2(a) are referred to herein as
a "DEMAND REGISTRATION."

            (b) Number of  Registrations.  The  Purchasers  and their  permitted
transferees  are  entitled  to  request  two (2)  Demand  Registrations,  in the
aggregate;  provided  that if the  Company is  eligible  to file a  registration
statement  on Form  S-3,  then  the  Initiating  Holders  shall  not  request  a
registration  on Form S-1. The Company shall use its reasonable  best efforts to
cause any such Demand  Registration  to become  effective  promptly,  and in any
event no later than one  hundred  (100) days after it  receives a request  under
Section 1.2(a) hereof; provided, that such one hundred (100) day period shall be
reduced to sixty (60) days if the Company is filing a Registration  Statement on
Form S-3.  Except as provided in Section 1.2(c) below, a registration  shall not
constitute  a Demand  Registration  until it has become  effective  and  remains
continuously  effective  for the  lesser  of (i) the  period  during  which  all
Registrable  Securities  registered in the Demand Registration are sold and (ii)
105 days; provided,  however,  that a registration shall not constitute a Demand
Registration if (x) after such Demand  Registration has become  effective,  such
registration  or  the  related  offer,   sale  or  distribution  of  Registrable
Securities thereunder is interfered with by any stop order,  injunction or other
order or  requirement of the SEC or other  governmental  agency or court for any
reason not attributable to the Initiating  Holders and such  interference is not
thereafter  eliminated  or (y)  the  conditions  specified  in the  underwriting
agreement,  if any, entered into in connection with such Demand Registration are
not  satisfied  or waived,  other than by reason of a failure by the  Initiating
Holders.

            (c)  Withdrawal.  If a  holder  of  Registrable  Securities  (each a
"DESIGNATED  HOLDER"  and  collectively,  the  "DESIGNATED  HOLDERS")  sends the
Company  a  written  request  for  inclusion  of part or all of such  Designated
Holder's Registrable Securities in a registration,  such Designated Holder shall
not be entitled to withdraw  or revoke such  request  without the prior  written
consent of the Company unless the Designated  Holders  reimburse the Company for
the  registration  expenses  set forth in Section  1.6(s)  with  respect to such
Demand Registration. If the Designated Holders fail to reimburse the Company for
such registration expenses, including, but

                                      -3-
<PAGE>

not limited to legal and accounting expenses, within thirty (30) days of receipt
of notice of such  registration  expenses,  then such request shall constitute a
Demand Registration,  unless such withdrawal or revocation was due to a material
adverse change to the Company.

            (d) Priority in Demand Registrations. If a Demand Registration is an
underwritten  offering  and the  managing  underwriters  advise  the  Company in
writing  that in their  opinion  the number of  Registrable  Securities  and, if
permitted hereunder, other securities requested to be included in such offering,
exceeds the number of Registrable Securities and other securities, if any, which
can be sold therein without materially and adversely affecting the marketability
of the offering (the "OFFERING QUANTITY"), then the Company will include in such
registration securities in the following priority:

                  (i) First,  for a demand made by the Initiating  Holders,  all
      Registrable  Securities owned by the Initiating  Holders and the number of
      shares to be offered for the account of all other Designated Holders,  pro
      rata,  based on the  amount of  Registrable  Securities  held by each such
      holder and the amount of Registrable  Securities held by all such holders,
      on an as converted basis. To the extent more than 22.5% of the Registrable
      Securities,  so requested to be registered by the  Initiating  Holders and
      the other  Designated  Holders are  excluded  from an offering  under this
      Section 1.2(d) (a "RELOAD Event"),  then the Designated Holders shall have
      the right to one additional Demand  Registration under, and subject to the
      limitations  of, Section 3.1 upon the occurrence of each Reload Event (but
      in no event  shall the  number of Demand  Registrations  pursuant  to this
      Agreement exceed a total of three Demand Registrations).

                  (ii)  Second,  the  number  of shares  to be  offered  for the
      account of the Company.

                  (iii)  Third,  to the extent (and only to the extent) that the
      Offering Quantity exceeds the aggregate amount of securities to be sold in
      clauses (i) and (ii),  the Company will include in such  registration  any
      other  Registrable  Securities  requested to be included in such offering,
      and if the  number  of such  other  holders'  securities  requested  to be
      included  exceeds the Offering  Quantity,  then the Company  shall include
      only  each  such  requesting  holder's  pro  rata  share  of the  Offering
      Quantity,  based on the amount of securities held by such holder, on an as
      converted  basis;  provided,  that no shares under  clauses (ii) and (iii)
      shall be included on the holder's first Demand Registration on Form S-3.

            (e)  Restrictions on Demand  Registrations.  The Company will not be
obligated to effect any Demand  Registration within 120 days after the effective
date of a previous Demand  Registration  or other  registration of securities of
the Company  (other than a shelf  registration  under Rule 415 of the Securities
Act or a  Registration  Statement on Form S-8) for the account of the Initiating
Holders (so long as at least two-thirds of the Registrable  Securities requested
to be included in such registration by the Initiating  Holders were included) or
any other Designated  Holder (so long as they had the opportunity to participate
in such  registration  and at least  two-thirds  of the  Registrable  Securities
requested to be included in such  registration  by the

                                      -4-
<PAGE>

Designated  Holders  were  included).  Such  120-day  period shall be reduced to
seventy five (75) days, if less than  two-thirds of the  Registrable  Securities
requested to be registered are included in such registration.  In addition,  the
Company will not be obligated to effect more than one Demand Registration within
a nine (9) month period.

            (f)  Selection  of   Underwriters.   In  connection  with  a  Demand
Registration that is an underwritten  offering, at the request of the Initiating
Holders  or  otherwise,   the  Company  shall  select  a  nationally  recognized
investment banking firm to administer the offering, such selection to be subject
to  the  approval  of  the  Initiating  Holders  which  approval  shall  not  be
unreasonably withheld.

            1.3 Form S-3  Registration.  If the  Company is eligible to use Form
S-3 under the Securities Act (or any similar  successor  form) and shall receive
from a Purchaser and its permitted  transferees (the "S-3 INITIATING HOLDERS") a
written  request or requests that the Company effect a registration on such Form
S-3,  including without  limitation,  pursuant to Rule 415 of the Securities Act
and any related  qualification  or compliance with respect to all or part of the
Registrable  Securities  owned by the S-3  Initiating  Holders and its permitted
transferees (provided,  that the S-3 Initiating Holders registering  Registrable
Securities in such registration  (together with all other holders of Registrable
Securities  to  be  included  in  such  registration)   propose  to  sell  their
Registrable  Securities at an aggregate price  (calculated based upon the Market
Price of the  Registrable  Securities on the date of filing of the Form S-3 with
respect  to  such  Registrable  Securities)  to  the  public  of  no  less  than
$1,000,000),  the Company shall (i) promptly give written notice of the proposed
registration,  and any related qualification or compliance, to all other holders
of Registrable Securities; and (ii) as soon as practicable,  use reasonable best
efforts to file and effect such  registration  and all such  qualifications  and
compliances  as may be so requested and as would permit or  facilitate  the sale
and  distribution  of all or such portion of the  Registrable  Securities as are
specified in such request,  together with all or such portion of the Registrable
Securities  of any other holder in the group of holders  joining in such request
as is specified in a written  request  given within  fifteen (15) days after the
holder's  receipt of such  written  notice  from the  Company.  No  registration
requested by any S-3  Initiating  Holders  pursuant to this Section 1.3 shall be
deemed a registration pursuant to Sections 1.1 or 1.2.

            1.4 Piggyback Registrations.

            (a) Right to  Piggyback.  Whenever the Company  proposes to register
any of its securities  under the Securities Act (other than pursuant to a Demand
Registration,  a registration  pursuant to Section 1.3 or a registration on Form
S-4 or S-8 or any successor or similar  forms) and the  registration  form to be
used may be used for the registration of Registrable Securities,  whether or not
for sale for its own account,  the Company will give prompt  written notice (but
in no event less than twenty five (25) days before the anticipated  filing date)
to all holders of  Registrable  Securities,  and such notice shall  describe the
proposed  registration  and distribution and offer to all holders of Registrable
Securities the  opportunity to register the number of Registrable  Securities as
each such holder may request. The Company will include in

                                      -5-
<PAGE>

such  registration all Registrable  Securities with respect to which the Company
has received  written  requests for inclusion  therein  within fifteen (15) days
after the holders' receipt of the Company's notice (a "PIGGYBACK REGISTRATION").

            (b) Reasonable  Efforts.  The Company shall use all reasonable  best
efforts  to  cause  the  managing  underwriter  or  underwriters  of a  proposed
underwritten  offering  to permit the  Registrable  Securities  requested  to be
included  in a  Piggyback  Registration  to be  included  on the same  terms and
conditions as any similar securities of the Company or any other security holder
included therein and to permit the sale or other disposition of such Registrable
Securities in accordance with the intended method of distribution thereof.

            (c)  Withdrawal.  Any  Designated  Holder  shall  have the  right to
withdraw  its  request  for  inclusion  of  its  Registrable  Securities  in any
Registration  Statement pursuant to this Section 1.4 by giving written notice to
the  Company of its  request to  withdraw;  provided,  that in the event of such
withdrawal (other than pursuant to Section 1.4(f) hereof,  the Company shall not
be required to reimburse  such holder for the fees and  expenses  referred to in
Section 1.6(s) hereof incurred by such holder prior to such  withdrawal,  unless
such withdrawal was due to a material adverse change to the Company. The Company
may withdraw a Piggyback  Registration  at any time prior to the time it becomes
effective.

            (d) Priority in  Registrations.  If a Piggyback  Registration  is an
underwritten  primary  registration  on behalf of the Company,  and the managing
underwriters  advise the  Company in writing  (with a copy to each party  hereto
requesting  registration  of Registrable  Securities)  that in their opinion the
number of Registrable  Securities  requested to be included on a secondary basis
in such  registration  exceeds  the  number  which can be sold in such  offering
without materially and adversely  affecting the marketability of such primary or
secondary  offering (the  "COMPANY  OFFERING  QUANTITY"),  then the Company will
include in such registration securities in the following priority:

                  (i) First, the Company will include the securities the Company
      proposes to sell.

                  (ii)  Second,   the  Company  will  include  all   Registrable
      Securities  requested to be included by any Designated  Holder, and if the
      number of such  Designated  Holders'  securities  requested to be included
      exceeds the Company Offering Quantity, then the Company shall include only
      each such  requesting  Designated  Holders'  pro rata  share of the shares
      available  for  registration  by the  Purchaser,  based on the  amount  of
      securities held by such holder, on an as converted basis.

            (e) Cutback.  If, as a result of the  proration  provisions  of this
Section  1.4,  any  Designated  Holders  shall not be  entitled  to include  all
Registrable  Securities in a Piggyback Registration that such Designated Holders
has  requested to be included,  such holder may elect to withdraw his request to
include  Registrable  Securities in such  registration  but the Company shall be
required  to  reimburse  such  holder for the fees and  expenses  referred to in
Section 1.7(b) hereof incurred by such holder prior to such withdrawal.

                                      -6-

            1.5 Holdback Agreements.

            (a) To the extent not  inconsistent  with  applicable  law, upon the
request of the Company or, in the case of an underwritten  public offering,  the
underwriters  managing such underwritten  offering of the Company's  securities,
each holder of Registrable  Securities  who owns at least 5% of the  outstanding
capital  stock of the  Company  on an  "as-converted"  basis or is an officer or
director of the Company will not effect any public sale or  distribution  (other
than those included in the  registration)  of any securities of the Company,  or
any  securities,   options  or  rights   convertible  into  or  exchangeable  or
exercisable  for such  securities  during the seven days prior to and the ninety
(90) -day period  beginning on such  effective  date,  unless (in the case of an
underwritten  public  offering) the managing  underwriters  otherwise agree to a
shorter  period of time.  Notwithstanding  the foregoing,  no Designated  Holder
shall be  required to enter into any such "lock up"  agreement  unless and until
all of the Company's  executive  officers and directors  execute identical "lock
up" agreements  and the Company uses  commercially  reasonable  efforts to cause
each  holder  of more  than  5% of its  outstanding  capital  stock  to  execute
identical  "lock up" agreements.  Neither the Company nor the underwriter  shall
amend,  terminate or waive a "lock up" agreement unless each "lock up" agreement
with a  Designated  Holder is also  amended  or  waived  in a similar  manner or
terminated, as the case may be.

            (b) The Company shall have the right at any time to require that the
Designated Holders of Registrable  Securities suspend further open market offers
and sales of Registrable  Securities pursuant to a Registration  Statement filed
hereunder whenever in the reasonable  judgment of the Company after consultation
with  counsel  there is or may be in  existence a Changing  Event (as defined in
Section 1.6(e)). The Company will give the Designated Holders notice of any such
suspension  and will use all  reasonable  best efforts to minimize the length of
such suspension.

            (c) The Company agrees not to effect any public sale or distribution
of any of its securities,  or any securities convertible into or exchangeable or
exercisable for such securities (except pursuant to registrations on Form S-4 or
S-8 or any successor thereto), during the period beginning on the effective date
of any  Registration  Statement in which the  Designated  Holders of Registrable
Securities are  participating and ending on the earlier of (i) the date on which
all Registrable  Securities  registered on such Registration  Statement are sold
and (ii)  forty  five (45) days after the  effective  date of such  Registration
Statement (except securities covered by such Registration Statement).

            1.6 Registration Procedures. Whenever any Registrable Securities are
required to be  registered  pursuant  to this  Agreement,  the Company  will use
reasonable  best  efforts  to  effect  the  registration  and  the  sale of such
Registrable  Securities in accordance  with the intended  methods of disposition
thereof, and pursuant thereto the Company will as expeditiously as possible:

            (a) prepare and file with the SEC on any form,  if not so  otherwise
provided for, for which the Company qualifies,  as soon as practicable after the
end of the period  within which  requests for  registration  may be given to the
Company, a Registration Statement with

                                      -7-
<PAGE>

respect to the offer and sale of such Registrable  Securities and thereafter use
reasonable best efforts to cause such Registration Statement to become effective
and remain  effective  until the  completion  of the  distribution  contemplated
thereby or the required time period under this  Agreement,  whichever is shorter
(and before filing such Registration Statement,  the Company will furnish to the
counsel  selected  by the holders of a majority  of the  Registrable  Securities
initiating such Registration  Statement copies of all such documents proposed to
be filed);  provided,  however,  that the Company may postpone for not more than
sixty (60) calendar days the filing or  effectiveness  of a Demand  Registration
Statement if the Board of Directors, in its good faith judgment, determines that
such registration could reasonably be expected to have a material adverse effect
on the Company and its stockholders including,  but not limited to, any proposal
or plan by the Company to engage in any acquisition of assets (other than in the
ordinary  course of  business)  or any merger,  consolidation,  tender  offer or
similar  transaction  then under  consideration  (in which event, the Designated
Holders  shall be entitled  to withdraw  such  request,  and if such  request is
withdrawn  such  registration  will  not  count  as a  Demand  Registration)  by
delivering written notice to the Designated  Holders who requested  inclusion of
Registrable  Securities in such  Registration  Statement of its determination to
postpone such Registration  Statement;  provided,  further, that (i) the Company
shall not  disclose any  information  that could be deemed  material  non-public
information to any holder of Registrable  Securities  included in a Registration
Statement that is subject to such postponement, (ii) in no event may the Company
postpone a filing  requested  hereunder more than twice in any twelve (12) month
period;  provided,  that any two postponements must be at least three (3) months
apart; provided,  further, that the Company shall delay the effectiveness of any
Demand  Registration  Statement  if the SEC rules and  regulations  prohibit the
Company from declaring a Registration  Statement effective because its financial
statements  are stale at a time when its fiscal year has ended or it has made an
acquisition  reportable under Item 2 of Form 8-K or any other similar  situation
until the  earliest  time in which the SEC would  allow the Company to declare a
Registration  Statement  effective  (provided  that the  Company  shall  use its
reasonable  best efforts to cure any such  situation as soon as possible so that
the Registration Statement can be made effective at the earliest possible time);

            (b) prepare and file with the SEC such amendments and supplements to
such Registration  Statement and the prospectus used in connection  therewith as
may be  necessary to keep such  Registration  Statement  effective  for a period
provided for in the  applicable  Section  above,  or if not so  provided,  for a
period of twelve (12) (for a registration pursuant to Rule 415 of the Securities
Act) or, if such  Registration  Statement  relates to an underwritten  offering,
such period as in the opinion of counsel for the  underwriters  a prospectus  is
required  by law  to be  delivered  in  connection  with  sales  of  Registrable
Securities  by an  underwriter  or dealer or (ii)  such  shorter  period as will
terminate when all of the securities covered by such Registration Statement have
been disposed of in accordance  with the intended  methods of disposition by the
seller or sellers thereof set forth in such  Registration  Statement (but in any
event  not  before  the  expiration  of any  longer  period  required  under the
Securities  Act),  and to comply with the  provisions of the Securities Act with
respect  to the  disposition  of all  securities  covered  by such  Registration
Statement  until such time as all of such  securities  have been  disposed of in
accordance  with the intended  methods of  disposition  by the seller or sellers
thereof set forth in

                                      -8-

<PAGE>

Holders  (which shall be designated by a majority in interest of the  Designated
Holders of Registrable Securities participating in the proposed sale pursuant to
the Registration  Statement in question);  provided,  however,  that the Company

            1.7 Indemnification.

            (a) The  Company  agrees  to  indemnify  and hold  harmless,  to the
fullest extent  permitted by law, each holder of Registrable  Securities and its
general or limited partners, officers,  directors, members, managers, employees,
advisors,   representatives,    agents   and   Affiliates   (collectively,   the
"REPRESENTATIVES")  from  and  against  any  loss,  claim,  damage,   liability,
attorney's  fees,  cost or expense and costs and expenses of  investigating  and
defending any such claim (collectively, the "LOSSES"), joint or several, and any
action in respect thereof to which such holder of Registrable  Securities or its
Representatives  may  become  subject  under the  Securities  Act or  otherwise,
insofar  as such  Losses  (or  actions  or  proceedings,  whether  commenced  or
threatened, in respect thereto) arise out of or are based upon (i) any untrue or
alleged  untrue  statement  of a material  fact  contained  in any  Registration
Statement,  prospectus or preliminary or summary  prospectus or any amendment or
supplement  thereto or (ii) any omission or alleged  omission to state therein a
material fact required to be stated  therein or necessary to make the statements
therein not  misleading,  and the Company  shall  reimburse  each such holder of
Registrable  Securities  and its  Representatives  for any  legal  or any  other
expenses  incurred by them in  connection  with  investigating  or  defending or
preparing  to defend  against  any such Loss,  action or  proceeding;  provided,
however,  that the  Company  shall  not be  liable  to any such  holder or other
indemnitee  in any such  case to the  extent  that any such  Loss (or  action or
proceeding,  whether commenced or threatened,  in respect thereof) arises out of
or is based upon an untrue  statement or alleged untrue statement or omission or
alleged omission,  made in such Registration  Statement,  any such prospectus or
preliminary  or summary  prospectus or any amendment or supplement  thereto,  in
reliance  upon,  and  in  conformity  with,  written  information  prepared  and
furnished  to the  Company  by such  holder  of  Registrable  Securities  or its
Representatives  expressly  for use  therein  or by  failure  of such  holder of
Registrable  Securities  to  deliver  a copy of the  Registration  Statement  or
prospectus  or any  amendments  or  supplements  thereto  after the  Company has
furnished  such holder of  Registrable  Securities  with a sufficient  number of
copies of the same. In connection  with an  underwritten  offering,  the Company
will indemnify such  underwriters,  their officers and directors and each Person
who controls such underwriters (within the meaning of the Securities Act) to the
same extent as provided above with respect to the indemnification of the holders
of Registrable Securities.

            (b) In  connection  with any  Registration  Statement  in which  the
holders of Registrable  Securities are participating pursuant to this Agreement,
the holders of  Registrable  Securities  will  furnish to the Company in writing
such information as the Company  reasonably  requests for use in connection with
any such  Registration  Statement  or  prospectus  and,  to the  fullest  extent
permitted by law, each such holder of Registrable Securities will indemnify and

                                      -12-
<PAGE>

hold harmless the Company and its  Representatives  from and against any Losses,
severally  but not  jointly,  and any  action in  respect  thereof  to which the
Company and its  Representatives  may become subject under the Securities Act or
otherwise, insofar as such Losses (or actions or proceedings,  whether commenced
or  threatened,  in  respect  thereof)  arise out of or are  based  upon (i) the
purchase or sale of Registrable  Securities  during a suspension as set forth in
Section  1.5(b) after  written  receipt of notice of such  suspension,  (ii) any
untrue  or  alleged  untrue  statement  of a  material  fact  contained  in  the
Registration  Statement,  prospectus or preliminary or summary prospectus or any
amendment or supplement  thereto, or (iii) any omission or alleged omission of a
material fact required to be stated  therein or necessary to make the statements
therein not misleading,  but, with respect to clauses (ii) and (iii) above, only
to  the  extent  that  such  untrue  statement  or  omission  is  made  in  such
Registration Statement, any such prospectus or preliminary or summary prospectus
or any amendment or supplement  thereto, in reliance upon and in conformity with
written  information  prepared  and  furnished  to the Company by such holder of
Registrable Securities expressly for use therein or by failure of such holder of
Registrable  Securities  to  deliver  a copy of the  Registration  Statement  or
prospectus  or any  amendments  or  supplements  thereto  after the  Company has
furnished  such holder of  Registrable  Securities  with a sufficient  number of
copies of the same, and such holder of Registrable Securities will reimburse the
Company and each  Representative for any legal or any other expenses incurred by
them in  connection  with  investigating  or  defending  or  preparing to defend
against any such Loss, action or proceeding; provided, however, that such holder
of  Registrable  Securities  shall not be liable in any such case to the  extent
that prior to the filing of any such  Registration  Statement or  prospectus  or
amendment or  supplement  thereto,  such holder of  Registrable  Securities  has
furnished  in  writing  to the  Company  information  expressly  for use in such
Registration  Statement or prospectus  or any  amendment or  supplement  thereto
which corrected or made not misleading  information  previously furnished to the
Company;  provided,  further,  however, that the obligation to indemnify will be
individual to each such holder of Registrable  Securities and will be limited to
the net amount of proceeds  received by such  holder of  Registrable  Securities
from the sale of Registrable Securities pursuant to such Registration Statement.

            (c)  Promptly  after  receipt  by any  Person  in  respect  of which
indemnity may be sought  pursuant to Section  1.7(a) or 1.7(b) (an  "INDEMNIFIED
PARTY")  of  notice  of  any  claim  or the  commencement  of  any  action,  the
Indemnified Party shall, if a claim in respect thereof is to be made against the
Person  against whom such  indemnity  may be sought (an  "INDEMNIFYING  PARTY"),
promptly  notify  the  Indemnifying  Party  in  writing  of  the  claim  or  the
commencement  of  such  action;   provided,  that  the  failure  to  notify  the
Indemnifying  Party shall not relieve the Indemnifying  Party from any liability
which it may have to an Indemnified Party otherwise than under Section 1.7(a) or
1.7(b) except to the extent of any actual prejudice resulting therefrom.  If any
such claim or action shall be brought against an Indemnified Party, and it shall
notify the Indemnifying Party thereof,  the Indemnifying Party shall be entitled
to  participate  therein,  and, to the extent that it wishes,  jointly  with any
other similarly notified  Indemnifying Party, to assume the defense thereof with
counsel reasonably  satisfactory to the Indemnified Party. After notice from the
Indemnifying  Party to the  Indemnified  Party of its  election  to  assume  the
defense of such claim or action,  the Indemnifying  Party shall not be liable to
the Indemnified Party for any

                                      -13-
<PAGE>

legal  or other  expenses  subsequently  incurred  by the  Indemnified  Party in
connection   with  the  defense   thereof   other  than   reasonable   costs  of
investigation;  provided,  that the  Indemnified  Party  shall have the right to
employ   separate   counsel  to  represent   the   Indemnified   Party  and  its
Representatives  who may be subject  to  liability  arising  out of any claim in
respect of which  indemnity may be sought by the  Indemnified  Party against the
Indemnifying  Party,  but the fees and expenses of such counsel shall be for the
account of such  Indemnified  Party  unless (i) the  Indemnifying  Party and the
Indemnified Party shall have mutually agreed to the retention of such counsel or
(ii) in the written opinion of counsel to such Indemnified Party, representation
of both  parties by the same  counsel  would be  inappropriate  due to actual or
potential conflicts of interest between them, it being understood, however, that
the  Indemnifying  Party  shall not,  in  connection  with any one such claim or
action or separate but substantially similar or related claims or actions in the
same jurisdiction  arising out of the same general allegations or circumstances,
be liable for the fees and expenses of more than one separate  firm of attorneys
(together  with  appropriate  local  counsel)  at any time  for all  Indemnified
Parties.  No Indemnifying Party shall,  without the prior written consent of the
Indemnified  Party,  effect any settlement of any claim or pending or threatened
proceeding  in  respect of which the  Indemnified  Party is or could have been a
party and indemnity could have been sought hereunder by such Indemnified  Party,
unless such settlement  includes an  unconditional  release of such  Indemnified
Party from all liability  arising out of such claim or proceeding other than the
payment  of  monetary  damages  by  the  Indemnifying  Party  on  behalf  of the
Indemnified Party.  Whether or not the defense of any claim or action is assumed
by the Indemnifying  Party, such  Indemnifying  Party will not be subject to any
liability for any settlement made without its consent, which consent will not be
unreasonably withheld.

            (d) If the  indemnification  provided  for in  this  Section  1.7 is
unavailable  to the  Indemnified  Parties in respect of any Losses  referred  to
herein,  then each Indemnifying  Party, in lieu of indemnifying such Indemnified
Party,  shall contribute to the amount paid or payable by such Indemnified Party
as a result of such Losses in such  proportion as is  appropriate to reflect the
relative benefits received by the Company on the one hand and the holders of the
Registrable  Securities  on the  other  from  the  offering  of the  Registrable
Securities,  or if such  allocation is not permitted by applicable  law, in such
proportion as is appropriate to reflect not only the relative  benefits but also
the  relative  fault  of the  Company  on the one hand  and the  holders  of the
Registrable  Securities  on the  other  in  connection  with the  statements  or
omissions which resulted in such Losses, as well as any other relevant equitable
considerations.  The  relative  fault of the Company on the one hand and of each
holder  of the  Registrable  Securities  on the  other  shall be  determined  by
reference to, among other things, whether any action taken, including any untrue
or alleged  untrue  statement  of a material  fact,  or the  omission or alleged
omission to state a material fact relates to information supplied by such party,
and  the  parties'  relative  intent,  knowledge,   access  to  information  and
opportunity to correct or prevent such statement or omission.

            The Company and the holders of the Registrable Securities agree that
it would not be just and  equitable  if  contribution  pursuant to this  Section
1.7(d)  were  determined  by pro  rata  allocation  or by any  other  method  of
allocation which does not take account of the equitable  considerations referred
to in the immediately preceding paragraph. The amount paid or payable

                                      -14-
<PAGE>

by an Indemnified Party as a result of the Losses referred to in the immediately
preceding  paragraph shall be deemed to include,  subject to the limitations set
forth above, any legal or other expenses reasonably incurred by such Indemnified
Party in connection  with  investigating  or defending any such action or claim.
Notwithstanding the provisions of this Section 1.7, no holder of the Registrable
Securities shall be required to contribute any amount in excess of the amount by
which the total price at which the  Registrable  Securities  of such holder were
offered to the public  exceeds  the amount of any Losses  which such  holder has
otherwise paid by reason of such untrue or alleged untrue  statement or omission
or alleged omission.  No Person guilty of fraudulent  misrepresentation  (within
the  meaning of  Section  11(f) of the  Securities  Act)  shall be  entitled  to
contribution   from  any  Person   who  was  not   guilty  of  such   fraudulent
misrepresentation.  Each holder's  obligations  to  contribute  pursuant to this
Section  1.7 is several in the  proportion  that the  proceeds  of the  offering
received  by such  holder  of the  Registrable  Securities  bears  to the  total
proceeds  of  the  offering  received  by all  the  holders  of the  Registrable
Securities and not joint.

            1.8 Participation in Underwritten Registrations.

            (a) No Person may participate in any registration hereunder which is
underwritten  unless such Person (i) agrees to sell such Person's  securities on
the basis provided in any  underwriting  arrangements  approved by the Person or
Persons  entitled  hereunder to approve such  arrangements  (including,  without
limitation,  pursuant to the terms of any  over-allotment or "green shoe" option
requested  by  the  managing  underwriter(s),  provided,  that  each  holder  of
Registrable  Securities  shall not be  required  to sell more than the number of
Registrable  Securities that such holder has requested the Company to include in
any registration) and (ii) completes and executes all questionnaires,  powers of
attorney,  indemnities,  underwriting  agreements and other documents reasonably
required under the terms of such underwriting arrangements and this Agreement.

            (b) Each Person that is participating in any registration  hereunder
agrees that, upon receipt of any notice from the Company of the happening of any
event of the kind described in Section 1.6(e) above,  such Person will forthwith
discontinue  the  disposition  of its  Registrable  Securities  pursuant  to the
Registration   Statement  until  such  Person's  receipt  of  the  copies  of  a
supplemented or amended prospectus as contemplated by such Section 1.6(e).

            1.9 Current Public  Information.  The Company covenants that it will
file all  reports  required to be filed by it under the  Securities  Act and the
Exchange Act and the rules and regulations  adopted by the SEC  thereunder,  and
will use  reasonable  best efforts to take such further  action as the Purchaser
may  reasonably  request,  all to the extent  required  to enable the holders of
Registrable  Securities to sell Registrable  Securities  pursuant to Rule 144 or
Rule 144A  adopted by the SEC under the  Securities  Act or any similar  rule or
regulation  hereafter adopted by the SEC. The Company shall, upon the request of
a Designated Holder, deliver to such Designated Holder a written statement as to
whether it has complied with such requirements.

and  conditions  of  the  Securities  Purchase  Agreement,  the  Certificate  of

            2.2 Transferees.  Any transferee to whom rights under this Agreement

obligations  imposed upon the Purchaser  under this Agreement to the same extent
as if such transferee were a Purchaser hereunder.

            2.3  Subsequent  Transferees.   A  transferee  to  whom  rights  are

Securities and shall be appropriately adjusted for any stock dividends,  splits,
reverse splits, combinations, recapitalizations and the like occurring after the
date hereof. The Company shall cause any successor or assign (whether by merger,

enter into any agreement  with respect to its  securities  that is  inconsistent
with the  rights  granted  to the  Purchasers  in this  Agreement  or grant  any
additional  registration  rights to any Person or with respect to any securities
which are not Registrable Securities which are prior in right to or inconsistent
with the rights granted in this Agreement.  The Purchasers expressly acknowledge
and agree that the Company has granted  registration rights to holders of Series
A-1  Preferred  Stock and Series A-2  Preferred  Stock  which are  substantially
identical to those granted to the Purchasers,  that such registration rights are
permitted under this Section 4.2, and that holders of such  registration  rights

Registrable Securities then in existence.

            4.3  Severability.   Whenever  possible,   each  provision  of  this

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 such provision or the remaining provisions of this
Agreement.

Dear Bruce:

      RE: Amendment "A" to Letter Agreement dated June 20, 2003
          -----------------------------------------------------

Hemoxymed, Inc. ("Company") and Equity Communications, LLC ("EC") entered into a
written agreement by letter dated June 20, 2003 (the "Letter Agreement"). A true
and accurate copy of the Letter Agreement is attached hereto as Exhibit "A" and
incorporated herein for all purposes.

The Company has subsequently changed its name to Applied NeuroSolutions.

Pursuant to the Letter Agreement, The Company has delivered to EC Common Stock
Purchase Warrant No. ANS-A-1 ("Warrant Document") on November 12, 2003.

Applied NeuroSolutions and EC now are desirous of amending the Letter Agreement
as set forth below, for valuable consideration, the receipt of which is hereby
acknowledged.

The provisions of paragraph number 3 are deleted and replaced with the
following, as set forth herein below:

       3.)    In addition to the compensation described in paragraph one above,
              Applied NeuroSolutions agrees to grant to EC and/or its assigns a
              warrant (the "Warrant") to purchase one million (1,000,000) of its
              common shares, at a price of twenty cents ($.20) per share, as
              compensation for services rendered.

       (3a)   The Warrant shall be fully vested on or before December 31, 2003.

       (3b)   The Warrant shall be exercisable at any time until it expires on
              September 2, 2008.

              shares underlying the Warrant in its next registration statement,
              which is expected to be submitted on or before March 31, 2003

their entirety except as otherwise provided for herein above.

The above amendments are agreed to modify the Letter Agreement. There are not
