                           ---------------------------

         This Investors' Rights Agreement (this "Agreement") is made and entered
into as of August 12, 2004, by and among LoyaltyPoint, Inc., a Delaware
corporation (the "Company"), and the persons and entities listed on Exhibit A
attached hereto (the "Investors").

         A. The Investors have agreed to purchase from the Company, and the
Company has agreed to sell to the Investors, shares of the Company's Series B
Preferred Stock (the "Series B Stock") and warrants to purchase Common Stock
(the "Warrants") on the terms and conditions set forth in that certain Series B
Preferred Stock and Common Stock Warrants Purchase Agreement, dated of even date
herewith by and among the Company and the Investors, as amended from time to
time (the "Series B Agreement").

         B. The Series B Agreement provides that the Investors shall be granted
certain information rights, registration rights, rights of first refusal and
rights to participate in public offerings, all as more fully set forth herein.

         NOW, THEREFORE, in consideration of the foregoing recitals and the
mutual promises hereinafter set forth and for other good and valuable
consideration, intending to be legally bound hereby the parties hereto agree as
follows:

1. INFORMATION RIGHTS. The Company covenants and agrees that, commencing on the
date of this Agreement, it shall furnish to each Investor, but only to the
extent requested by such Investor, audited annual financial statements and
unaudited quarterly financial statements. Any financial statements provided
under this Section 1 shall be prepared on a consolidated basis and in compliance
with generally accepted accounting principles, and shall include, at a minimum,
a balance sheet, statement of income and statement of cash flows. To the extent
requested by an Investor, the Company shall also furnish to such Investor as
soon as practicable and in any event no later than thirty (30) days after the
close of each fiscal year of the Company, an annual operating plan and budget,
prepared on a monthly basis, for the next immediate fiscal year, and, within a
reasonable time of its preparation, any amendments to the annual budget. The
Company shall permit each Investor, at such Investor's expense, to visit and
inspect the Company's properties, to examine its books of account and records
and to discuss the Company's affairs, finances and accounts with its officers,
all at such reasonable times as may be requested by such Investor; provided,
however, the Investor shall notify the Company in advance of the time and place
of any intended inspection and the Investor shall be entitled to not more than
twelve (12) inspections in any twelve-month period.

2. REGISTRATION RIGHTS.

          2.1 Definitions. For purposes of this Section 2:

          (a) Registration. The terms "register," "registration" and
"registered" refer to a registration effected by preparing and filing a
registration statement in compliance with the Securities Act, and the
declaration or ordering of effectiveness of such registration statement.

          (b) Registrable Securities. The term "Registrable Securities" means:

<PAGE>

               (1) any shares Common Stock of the Company (the "Common Stock")
issued or issuable upon the conversion of any shares of Series B Stock issued
under the Series B Agreement or issued or issuable upon exercise of the Warrants
that are now owned or may hereafter be acquired by any Investor or any
Investor's permitted successors and assigns;

               (2) any shares of Common Stock issued (or issuable upon the
conversion or exercise of any warrant, right or other security which is issued)
(i) as a dividend or other distribution to the shares described above, (ii) upon
any stock split, stock dividend, recapitalization or similar event, or (iii)
otherwise issued or issuable with respect to the shares described above;
excluding in all cases, however, any Registrable Securities sold by a person in
a transaction in which rights under this Section 2 are not assigned in
accordance with this Agreement or any Registrable Securities with respect to
which, pursuant to Section 2.10 hereof, the holders are no longer entitled to
registration rights pursuant to Sections 2.2, 2.3 or 2.4 hereof.

          (c) Registrable Securities Then Outstanding. The number of shares of
"Registrable Securities then outstanding" shall mean the number of shares of
Common Stock which are Registrable Securities that are then (1) issued and
outstanding or (2) issuable pursuant to the exercise or conversion of then
outstanding and then exercisable and qualifying options, warrants or convertible
securities.

          (d) Holder. The term "Holder" means any person owning of record
Registrable Securities or any assignee of record of such Registrable Securities
to whom rights set forth herein have been duly assigned in accordance with this
Agreement; provided, however, that for purposes of this Agreement, a record
holder of shares of Series B Stock convertible into such Registrable Securities
and/or Warrants exercisable for Registrable Securities shall be deemed to be the
Holder of such Registrable Securities.

          (e) Form S-3. The term "Form S-3" means such form under the Securities
Act as is in effect on the date hereof or any successor registration form under
the Securities Act of 1933 ("Securities Act") subsequently adopted by the SEC
that permits inclusion or incorporation of substantial information by reference
to other documents filed by the Company with the SEC.

          (f) SEC. The term "SEC" or "Commission" means the U.S. Securities and
Exchange Commission.

2.2 DEMAND REGISTRATION.

          (a) Request by Holders. If the Company shall receive a written request
from the Holders of a majority of the Registrable Securities then outstanding
that the Company file a registration statement under the Securities Act covering
the registration of Registrable Securities pursuant to this Section 2.2, then
the Company shall, within twenty (20) days after the receipt of such written
request, give written notice of such request (the "Request Notice") to all
Holders, and effect, as soon as practicable, the registration under the
Securities Act of all Registrable Securities which Holders request to be
registered and included in such registration by written notice given by such
Holders to the Company within twenty (20) days after receipt of the Request
Notice, subject only to the limitations of this Section 2; provided that

                                       2
<PAGE>

the Registrable Securities requested by all Holders to be registered pursuant to
such request must have an anticipated aggregate public offering price (before
any underwriting discounts and commissions) of not less than Three Million
Dollars ($3,000,000).

          (b) Underwriting. If the Holders initiating the registration request
under this Section 2.2 (the "INITIATING HOLDERS") intend to distribute the
Registrable Securities covered by their request by means of an underwriting,
then they shall so advise the Company as a part of their request made pursuant
to this Section 2.2 and the Company shall include such information in the
written notice referred to in subsection 2.2(a). In such event, the right of any
Holder to include his, her, or its Registrable Securities in such registration
shall be conditioned upon such Holder's participation in such underwriting and
the inclusion of such Holder's Registrable Securities in the underwriting
(unless otherwise mutually agreed by a majority in interest of the Initiating
Holders and such Holder) to the extent provided herein. All Holders proposing to
distribute their securities through such underwriting shall enter into an
underwriting agreement in customary form with the managing underwriter or
underwriters selected for such underwriting by a majority in interest of the
Initiating Holders. Notwithstanding any other provision of this Section 2.2, if
the underwriter(s) advise(s) the Company in writing that marketing factors
require a limitation of the number of securities to be underwritten then the
Company shall so advise all Holders of Registrable Securities that would
otherwise be registered and underwritten pursuant hereto, and the number of
Registrable Securities that may be included in the underwriting shall be reduced
as required by the underwriter(s) and allocated among the Holders of Registrable
Securities on a pro rata basis according to the number of Registrable Securities
then outstanding held by each Holder requesting registration (including the
Initiating Holders); provided, however, that the number of shares of Registrable
Securities to be included in such underwriting and registration shall not be
reduced unless all other securities of the Company are first entirely excluded
from the underwriting and registration. Any Registrable Securities excluded and
withdrawn from such underwriting shall be withdrawn from the registration.

          (c) Maximum Number of Demand Registrations. The Company is obligated
to effect only one (1) such registrations pursuant to this Section 2.2.

          (d) Deferral. Notwithstanding the foregoing, if the Company shall
furnish to Holders requesting the filing of a registration statement pursuant to
this Section 2.2, a certificate signed by the President or Chief Executive
Officer of the Company stating that in the good faith judgment of the Board of
Directors of the Company, it would be seriously detrimental to the Company and
its shareholders for such registration statement to be filed or declared
effective and it is therefore essential to defer the filing of such registration
statement or the registration process, as the case may be, then the Company
shall have the right to defer such filing or delay the registration process for
a period of not more than ninety (90) days after receipt of the request of the
Initiating Holders; provided, however, that the Company may not utilize this
right more than once in any twelve (12) month period.

          (e) Expenses. All expenses incurred in connection with a registration
pursuant to this Section 2.2, including without limitation all registration and
qualification fees, printers' and accounting fees, fees and disbursements of
counsel for the Company, and the reasonable fees and disbursements of one
counsel for the selling Holders (but excluding

                                       3
<PAGE>

underwriters' discounts and commissions), shall be borne by the Company. Each
Holder participating in a registration pursuant to this Section 2.2 shall bear
such Holder's proportionate share (based on the number of shares sold by such
Holder over the total number of shares included in such registration at the time
it is declared effective) of all discounts, commissions or other amounts payable
to underwriters or brokers in connection with such offering. Notwithstanding the
foregoing, the Company shall not be required to pay for any expenses of any
registration proceeding begun pursuant to this Section 2.2 if the registration
request is subsequently withdrawn at the request of the Holders of a majority of
the Registrable Securities to be registered, unless the Holders of a majority of
the Registrable Securities then outstanding agree to forfeit their right to one
(1) demand registration pursuant to this Section 2.2 (in which case such right
shall be forfeited by all Holders of Registrable Securities); provided, further,
however, that if at the time of such withdrawal, the Holders have learned of a
material adverse change in the condition, business, or prospects of the Company
not known to the Holders at the time of their request for such registration and
have withdrawn their request for registration with reasonable promptness after
learning of such material adverse change, then the Holders shall not be required
to pay any of such expenses and shall retain their demand registration rights
pursuant to this Section 2.2.

          2.3 PIGGYBACK REGISTRATIONS. The Company shall notify all Holders of
Registrable Securities in writing at least thirty (30) days prior to filing any
registration statement under the Securities Act for purposes of effecting a
public offering of securities of the Company (including, but not limited to,
registration statements relating to secondary offerings of securities of the
Company, but excluding registration statements relating to any registration
under Section 2.2 or Section 2.4 of this Agreement or to any employee benefit
plan or a corporate reorganization or other transaction covered by Rule 145
promulgated under the Securities Act, or a registration on any registration form
which does not permit secondary sales or does not include substantially the same
information as would be required to be included in a registration statement
covering the sale of Registrable Securities,) and will afford each such Holder
an opportunity to include in such registration statement all or any part of the
Registrable Securities then held by such Holder. Each Holder desiring to include
in any such registration statement all or any part of the Registrable Securities
held by such Holder shall, within twenty (20) days after receipt of the
above-described notice from the Company, so notify the Company in writing, and
in such notice shall inform the Company of the number of Registrable Securities
such Holder wishes to include in such registration statement. If a Holder
decides not to include all of its Registrable Securities in any registration
statement thereafter filed by the Company, such Holder shall nevertheless
continue to have the right to include any Registrable Securities in any
subsequent registration statement or registration statements as may be filed by
the Company with respect to offerings of its securities, all upon the terms and
conditions set forth herein.

          (a) Underwriting. If a registration statement under which the Company
gives notice under this Section 2.3 is for an underwritten offering, then the
Company shall so advise the Holders of Registrable Securities. In such event,
the right of any such Holder's Registrable Securities to be included in a
registration pursuant to this Section 2.3 shall be conditioned upon such
Holder's participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting to the extent provided herein. All
Holders proposing to distribute their Registrable Securities through such
underwriting shall enter into an underwriting agreement in customary form with
the managing underwriter or underwriter(s)

                                       4
<PAGE>

selected for such underwriting. Notwithstanding any other provision of this
Agreement, if the managing underwriter determine(s) in good faith that marketing
factors require a limitation of the number of shares to be underwritten, then
the managing underwriter(s) may exclude shares (including Registrable
Securities) from the registration and the underwriting, and the number of shares
that may be included in the registration and the underwriting shall be
allocated, first, to the Company, and second to Holders requesting inclusion of
their Registrable Securities in such registration statement on a pro rata basis
based on the number of Registrable Securities each such Holder has requested to
be included in the registration; provided however, that the right of the
underwriters to exclude shares (including Registrable Securities) from the
registration and underwriting as described above shall be restricted so that:
(i) the number of Registrable Securities included in any such registration is
not reduced below thirty percent (30%) of the shares included in the
registration, and (ii) all shares that are not either being sold for the account
of the Company or Registrable Securities shall first be excluded from such
registration and underwriting before any Registrable Securities are so excluded.
If any Holder disapproves of the terms of any such underwriting, such Holder may
elect to withdraw therefrom by written notice, given in accordance with Section
6.1 hereof, to the Company and the underwriter, delivered at least twenty (20)
days prior to the effective date of the registration statement. Any Registrable
Securities excluded or withdrawn from such underwriting shall be excluded and
withdrawn from the registration. For any Holder that is a partnership or
corporation, the partners, retired partners and shareholders of such Holder, or
the estates and family members of any such partners and retired partners and any
trusts for the benefit of any of the foregoing persons shall be deemed to be a
single "Holder," and any pro rata reduction with respect to such "Holder" shall
be based upon the aggregate amount of shares carrying registration rights owned
by all entities and individuals included in such "Holder," as defined in this
sentence.

          (b) Expenses. All expenses incurred in connection with a registration
pursuant to this Section 2.3, including without limitation all registration and
qualification fees, printers' and accounting fees, fees and disbursements of
counsel for the Company, and the reasonable fees and disbursements of one
counsel for the selling Holders (but excluding underwriters' discounts and
commissions), shall be borne by the Company. Each Holder participating in a
registration pursuant to this Section 2.3 shall bear such Holder's proportionate
share (based on the number of shares sold by such Holder over the total number
of shares included in such registration at the time it goes effective) of all
discounts, commissions or other amounts payable to underwriters or brokers in
connection with such offering.

     2.4 FORM S-3 REGISTRATION. In case the Company shall receive from any
Holder or Holders of at least thirty percent (30%) of Registrable Securities
then outstanding a written request or requests that the Company effect a
registration on Form S-3 and any related qualification or compliance with
respect to all or a part of the Registrable Securities owned by such Holder or
Holders, then the Company will do the following:

          (a) Notice. Promptly give written notice of the proposed registration
and the Holder's or Holders' request therefor, and any related qualification or
compliance, to all other Holders of Registrable Securities.

          (b) Registration. As soon as practicable, effect such registration and
all such qualifications and compliances as may be so requested and as would
permit or facilitate

                                       5
<PAGE>

the sale and distribution of all or such portion of such Holder's or Holders'
Registrable Securities as are specified in such request, together with all or
such portion of the Registrable Securities of any other Holder or Holders
joining in such request as are specified in a written request given within
twenty (20) days after receipt of such written notice from the Company;
provided, however, that the Company shall not be obligated to effect any such
registration, qualification or compliance pursuant to this Section 2.4:

               (1) if Form S-3 is not available for such offering;

               (2) if the Holders, together with the holders of any other
securities of the Company entitled to inclusion in such registration, propose to
sell Registrable Securities and such other securities (if any) at an aggregate
price to the public of less than Three Million Dollars ($3,000,000);

               (3) if the Company shall furnish to the Holders a certificate
signed by the President or Chief Executive Officer of the Company stating that
in the good faith judgment of the Board of Directors of the Company, it would be
seriously detrimental to the Company and its shareholders for such Form S-3
Registration to be effected at such time or declared effective, in which event
the Company shall have the right to defer the filing or the registration
process, as the case may be, of the Form S-3 registration statement no more than
once during any twelve (12) month period for a period of not more than ninety
(90) days after receipt of the request of the Holder or Holders under this
Section 2.4;

               (4) if the Company has, within the twelve (12) month period
preceding the date of such request, already effected two (2) registrations on
Form S-3 for the Holders pursuant to this Section 2.4; or

               (5) in any particular jurisdiction in which the Company would be
required to qualify to do business or to execute a general consent to service of
process in effecting such registration, qualification or compliance.
Notwithstanding the foregoing provisions of this clause (5), the Company shall
not be required to register or qualify the Registrable Securities in any
jurisdiction that imposes a merit review or fairness approach in connection with
federally registered offerings unless the Registrable Securities proposed to be
sold would be "covered securities" under Section 18 of the Securities Act.

          (c) Expenses. Subject to the foregoing, the Company shall file a Form
S-3 registration statement covering the Registrable Securities and other
securities so requested to be registered pursuant to this Section 2.4 as soon as
practicable after receipt of the request or requests of the Holders for such
registration. The Company shall pay all expenses incurred in connection with
each registration requested pursuant to this Section 2.4 in any twelve-month
period, (excluding underwriters' or brokers' discounts and commissions),
including without limitation all filing, registration and qualification,
printers' and accounting fees and the reasonable fees and disbursements of one
(1) counsel for the selling Holder or Holders and counsel for the Company;
provided, however, that the Company shall only be obligated to pay the
reasonable fees and disbursements of one (1) counsel for the selling Holder or
Holders for the first registration effected pursuant to this Section 2.4 in a
particular twelve-month period. Each Holder participating in a registration
pursuant to this Section 2.4 shall bear

                                       6
<PAGE>

such Holder's proportionate share (based on the number of shares sold by such
Holder over the total number of shares included in such registration at the time
it goes effective) of all discounts, commissions or other amounts payable to
underwriters or brokers in connection with such offering and the fees and
disbursements of any counsel for the participating Holders (in the case of any
second registration effected pursuant to this Section 2.4 in a particular
twelve-month).

               (d) Not Demand Registration. Form S-3 registrations shall not be
deemed to be demand registrations as described in Section 2.2 above.

     2.5 OBLIGATIONS OF THE COMPANY. Whenever required to effect the
registration of any Registrable Securities under this Agreement, the Company
shall, subject to the terms hereof, as expeditiously as reasonably possible:

               (a) Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use reasonable efforts to cause such
registration statement to become effective, and, upon the request of the Holders
of a majority of the Registrable Securities registered thereunder, keep such
registration statement effective until the earlier of: (i) the sale of the
registrable securities registered thereunder or (ii) one hundred twenty (120)
days from the effective date of the registration statement;

               (b) Prepare and file with the SEC such amendments and supplements
to such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Securities Act with respect to the disposition of all securities covered by such
registration statement.

               (c) Furnish to the Holders such number of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Securities Act, and such other documents as they may reasonably request in order
to facilitate the disposition of the Registrable Securities owned by them that
are included in such registration.

               (d) Use reasonable efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by the Holders,
provided that the Company shall not be required in connection therewith or as a
condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions. Notwithstanding the
foregoing provisions of this clause (5), the Company shall not be required to
register or qualify the Registrable Securities in any jurisdiction that imposes
a merit review or fairness approach in connection with federally registered
offerings unless the Registrable Securities proposed to be sold would be
"covered securities" under Section 18 of the Securities Act.

               (e) In the event of any underwritten public offering, enter into
and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing underwriter(s) of such offering. Each Holder
participating in such underwriting hereby agrees to also enter into and perform
its obligations under such an agreement.

               (f) Notify each Holder of Registrable Securities covered by such
registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event
as a result of which the prospectus

                                       7
<PAGE>

included in such registration statement, as then in effect, includes an untrue
statement of a material fact or omits to state a material fact required to be
stated therein or necessary to make the statements therein not misleading in the
light of the circumstances then existing and at the request of any such Holder,
prepare promptly and furnish to such Holder a reasonable number of copies of a
supplement to or an amendment of such prospectus as may be necessary so that, as
thereafter delivered to the purchaser of such shares, such prospectus shall not
include an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading or incomplete in the light of the circumstances then existing.

               (g) Furnish, at the request of any Holder requesting registration
of Registrable Securities, on the date that such Registrable Securities are
delivered to the underwriters for sale, if such securities are being sold
through underwriters, or, if such securities are not being sold through
underwriters, on the date that the registration statement with respect to such
securities becomes effective: (1) an opinion, dated as of such date, of the
counsel representing the Company for the purposes of such registration, in form
and substance as is customarily given to underwriters in an underwritten public
offering and reasonably satisfactory to a majority in interest of the Holders
requesting registration, addressed to the underwriters, if any, and to the
Holders requesting registration of Registrable Securities and (2) if such
securities are being sold through underwriters, a "comfort" letter dated as of
such date, from the independent certified public accountants of the Company, in
form and substance as is customarily given by independent certified public
accountants to underwriters in an underwritten public offering and reasonably
satisfactory to a majority in interest of the Holders requesting registration,
addressed to the underwriters, if any, and to the Holders requesting
registration of Registrable Securities.

               (h) Make available for inspection by any Holder participating in
such registration, any underwriter participating in any disposition pursuant to
such registration, and any attorney or accountant retained by any such Holder or
underwriter, all financial and other records, pertinent corporate documents and
properties of the Company, and cause the Company's officers and directors to
supply all information reasonably requested by any such Holder, underwriter,
attorney or accountant in connection with such registration statement; provided,
however, that such Holder, underwriter, attorney or accountant shall agree to
hold in confidence and trust all information so provided.

               (i) In the event that, in the reasonable judgment of the Company,
it is advisable to suspend use of a prospectus included in an effective
registration statement due to pending material developments or other events that
have not yet been publicly disclosed and as to which the Company reasonably
believes public disclosure would be detrimental to the Company and its
stockholders, the Company shall notify all Holders participating in the offering
to such effect, and, upon receipt of such notice, each such Holder shall
immediately discontinue any sales of Registrable Securities pursuant to such
registration statement until such Holder has received copies of a supplemental
or amended prospectus or until such Holder is advised in writing by the Company
that the then current prospectus may be used and has received copies of any
additional or supplemental filings that are incorporated or deemed incorporated
by reference in such prospectus. Notwithstanding anything to the contrary
herein, the Company shall not exercise its rights under this Section 2.5(i) to
suspend sales of Registrable Securities for a period

                                       8
<PAGE>

in excess of 30 days consecutively or 60 days in any 365-day period, and any
such suspension shall extend the Company's obligations under this Section 2.5 on
a day-for-day basis.

     2.6 FURNISH INFORMATION. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to Sections 2.2, 2.3 or
2.4 that the selling Holders shall furnish to the Company such information
regarding themselves, the Registrable Securities held by them, and the intended
method of disposition of such securities as shall be required to timely effect
the registration of their Registrable Securities.

     2.7 DELAY OF REGISTRATION. No Holder shall have any right to obtain or seek
an injunction restraining or otherwise delaying any such registration as the
result of any controversy that might arise with respect to the interpretation or
implementation of this Section 2.

     2.8 INDEMNIFICATION. In the event any Registrable Securities are included
in a registration statement under Sections 2.2, 2.3 or 2.4:

          (a) By the Company. To the extent permitted by law, the Company will
indemnify and hold harmless each Holder, each of its current and former
officers, directors, partners, members, managers and each person controlling
such Holder, any underwriter (as defined in the Securities Act) for such Holder
and each person, if any, who controls such Holder or underwriter within the
meaning of the Securities Act or the Securities Exchange Act of 1934, as
amended, (the "Exchange Act"), against any losses, claims, damages, or
liabilities (joint or several) to which they may become subject under the
Securities Act, the Exchange Act or other federal or state law, insofar as such
losses, claims, damages, or liabilities (or actions in respect thereof) arise
out of or are based upon any of the following statements, omissions or
violations (collectively, the "Violations" and, individually, a "Violation"):

               (1) any untrue statement or alleged untrue statement of a
material fact contained in such registration statement, including any
preliminary prospectus or final prospectus contained therein or any amendments
or supplements thereto; or

               (2) the omission or alleged omission to state therein a material
fact required to be stated therein, or necessary to make the statements therein
not misleading; or

               (3) any violation or alleged violation by the Company of the
Securities Act, the Exchange Act, any federal or state securities law or any
rule or regulation promulgated under the Securities Act, the Exchange Act or any
federal or state securities law in connection with the offering covered by such
registration statement.

The Company will reimburse each such Holder, officer, director, partner, member,
manager, underwriter or controlling person for any legal or other expenses
reasonably incurred by them, within three months after a request for
reimbursement has been received by the Company, in connection with investigating
or defending any such loss, claim, damage, liability or action; provided
however, that the indemnity agreement contained in this subsection 2.8(a) shall
not apply to amounts paid in settlement of any such loss, claim, damage,
liability or action if such settlement is effected without the consent of the
Company (which consent shall not be unreasonably withheld), nor shall the
Company be liable in any such case for any such loss,

                                       9
<PAGE>

claim, damage, liability or action to the extent that it arises out of or is
based upon a Violation which occurs in reliance upon and in conformity with
written information furnished expressly for use in connection with such
registration by such Holder, partner, officer, director, underwriter, manager,
member or controlling person of such Holder.

          (b) By Selling Holders. To the extent permitted by law, each selling
Holder will indemnify and hold harmless the Company, each of its directors, each
of its officers who have signed the registration statement, each person, if any,
who controls the Company within the meaning of the Securities Act, any
underwriter and any other Holder selling securities under such registration
statement or any of such other Holder's partners, members, managers, directors
or officers or any person who controls such Holder within the meaning of the
Securities Act or the Exchange Act, against any losses, claims, damages or
liabilities (joint or several) to which the Company or any such director,
officer, controlling person, underwriter or other such Holder, partner, member,
manager, director, officer or controlling person of such other Holder may become
subject under the Securities Act, the Exchange Act or other federal or state
law, insofar as such losses, claims, damages or liabilities (or actions in
respect thereto) arise out of or are based upon any Violation, in each case to
the extent (and only to the extent) that such Violation occurs in reliance upon
and in conformity with written information furnished by such Holder expressly
for use in connection with such registration. Each such Holder will reimburse
any legal or other expenses reasonably incurred by the Company or any such
director, officer, controlling person, underwriter or other Holder, partner,
member, manager, officer, director or controlling person of such other Holder in
connection with investigating or defending any such loss, claim, damage,
liability or action; within three months after a request for reimbursement has
been received by the indemnifying Holder, provided, however, that the indemnity
agreement contained in this subsection 2.8(b) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the Holder, which consent shall
not be unreasonably withheld; and provided further, that the total amounts
payable in indemnity by a Holder under this Section 2.8(b) in respect of any
Violation shall not exceed the net proceeds received by such Holder in the
registered offering out of which such Violation arises.

          (c) Notice. Promptly after receipt by an indemnified party under this
Section 2.8 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 2.8, deliver to
the indemnifying party a written notice of the commencement thereof. The
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the fees and expenses to be paid
by the indemnifying party, if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual
or potential conflict of interests between such indemnified party and any other
party represented by such counsel in such proceeding. The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if prejudicial to its ability to defend such
action, shall relieve such indemnifying party of any liability to the
indemnified party under this Section 2.8, but the omission so to deliver written
notice to the indemnifying party

                                       10
<PAGE>

will not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 2.8.

          (d) Defect Eliminated in Final Prospectus. The foregoing indemnity
agreements of the Company and Holders are subject to the condition that, insofar
as they relate to any Violation made in a preliminary prospectus but eliminated
or remedied in the amended prospectus on file with the SEC at the time the
registration statement in question becomes effective or the amended prospectus
filed with the SEC pursuant to SEC Rule 424(b) (the "Final Prospectus"), such
indemnity agreement shall not inure to the benefit of any person if a copy of
the Final Prospectus was furnished to the indemnified party and was not
furnished to the person asserting the loss, liability, claim or damage at or
prior to the time such action is required by the Securities Act.

          (e) Contribution. If the indemnification provided for in this Section
2.8 is held by a court of competent jurisdiction to be unavailable to an
indemnified party with respect to any loss, liability, claim, damage or expense
referred to herein, then the indemnifying party, in lieu of indemnifying the
indemnified party, shall contribute to the amount paid or payable by such
indemnified party with respect to such loss, liability, claim, damage or expense
in the proportion that is appropriate to reflect the relative fault of the
indemnifying party and the indemnified party in connection with the statements
or omissions that resulted in such loss, liability, claim, damage or expense, as
well as any other relevant equitable considerations. The relative fault of the
indemnifying party and the indemnified party shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of
material fact or the omission to state a material fact relates to information
supplied by the indemnifying party or by the indemnified party, and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission. In any such case, (A) no such Holder will be
required to contribute any amount in excess of the public offering price of all
such Registrable Securities offered and sold by such Holder pursuant to such
registration statement; and (B) no person or entity guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
will be entitled to contribution from any person or entity who was not guilty of
such fraudulent misrepresentation.

          (f) Conflict with Underwriting Agreement. Notwithstanding the
foregoing, to the extent that the provisions on indemnification and contribution
contained in the underwriting agreement entered into in connection with the
underwritten public offering are in conflict with the foregoing provisions, the
provisions in the underwriting agreement will control.

          (g) Survival. The obligations of the Company and Holders under this
Section 2.8 shall survive the completion of any offering of Registrable
Securities in a registration statement, and otherwise.

     2.9 RULE 144 REPORTING. With a view to making available the benefits of
certain rules and regulations of the Commission which may at any time permit the
sale of the Registrable Securities to the public without registration, the
Company agrees to:

          (a) Make and keep public information available, as those terms are
understood and defined in Rule 144 under the Securities Act;

                                       11
<PAGE>

          (b) File with the Commission in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange Act;
and

          (c) So long as a Holder owns any Registrable Securities, to furnish to
the Holder forthwith upon request a written statement by the Company as to its
compliance with the reporting requirements of said Rule 144, and of the
Securities Act and the Exchange Act, a copy of the most recent annual or
quarterly report of the Company, and such other reports and documents of the
Company as a Holder may reasonably request in availing itself of any rule or
regulation of the Commission allowing a Holder to sell any such securities
without registration.

          2.10 TERMINATION OF THE COMPANY'S OBLIGATIONS. The Company shall have
no obligations pursuant to Sections 2.2 through 2.4 with respect to: (a) any
request or requests for registration made by any Holder after the fifth
anniversary of the date of this Agreement; or (b) any Registrable Securities
proposed to be sold by a Holder in a registration pursuant to Section 2.2, 2.3
or 2.4 which may be sold in a three (3) month period without registration under
the Securities Act pursuant to Rule 144 under the Securities Act.

          2.11 LIMITATIONS ON SUBSEQUENT REGISTRATION RIGHTS. From and after the
date of this Agreement, the Company shall not, without the prior written consent
of the Holders of a majority of the Registrable Securities then outstanding,
enter into any agreement with any holder or prospective holder of any securities
of the Company that would grant registration rights with respect to such
securities, unless such registration rights are subordinate in every respect to
the registration rights of the Holders hereunder.

     3. RIGHT OF FIRST REFUSAL.

          3.1 GENERAL. Each Holder and any party to whom such Holder's rights
under this Section 3 have been duly assigned in accordance with Section 5.1(a)
(each such Holder or assignee being hereinafter referred to as a "RIGHTS
HOLDER") has the right of first refusal to purchase such Rights Holder's Pro
Rata Share (as defined below), of all (or any part) of any "New Securities" (as
defined in Section 3.2) that the Company may from time to time issue after the
date of this Agreement. A Rights Holder's "PRO RATA SHARE" for purposes of this
right of first refusal is the ratio of (a) the number of Registrable Securities
as to which such Rights Holder is the Holder, to (b) a number of shares of
Common Stock equal to the sum of (1) the total number of shares of Common Stock
then outstanding plus (2) the total number of shares of Common Stock into which
all then outstanding shares of Preferred Stock of the Company are then
convertible.

          3.2 NEW SECURITIES. "NEW SECURITIES" shall mean any Common Stock or
Preferred Stock of the Company, whether now authorized or not, and rights,
options or warrants to purchase such Common Stock or Preferred Stock, and
securities of any type whatsoever that are, or may become, convertible or
exchangeable into such Common Stock or Preferred Stock; provided, however, that
the term "New Securities" does not include:

               (a) shares of Common Stock issued or issuable upon conversion of
the outstanding shares of all the series of the Preferred Stock;

                                       12
<PAGE>

               (b) shares of Common Stock (or options, warrants or rights
therefor) granted or issued hereafter to employees, officers, directors,
contractors, consultants or advisers to, the Company or any Subsidiary pursuant
to the Company's current Equity Incentive Plan or the Company's new equity
incentive plan to be implemented in 2004;

               (c) up to 1,000,000 shares of the Company's Common Stock or
Preferred Stock (and/or options or warrants therefor) issued or issuable to
equipment lessors, service providers or lenders under arrangements approved by
the Company's Board of Directors ("Board");

               (d) any shares of Common Stock issued upon the exercise of the
Warrants;

               (e) any shares of Common Stock issued upon the conversion of the
Series B Stock issued pursuant to the Series B Agreement;

               (f) shares of Common Stock or Preferred Stock issuable upon
exercise of any options, warrants or rights to purchase any securities of the
Company outstanding as of the date of this Agreement, subject to adjustments
pursuant to the terms thereof, and any securities issuable upon the conversion
thereof;

               (g) shares of the Company's Common Stock or Preferred Stock
issued in connection with any stock split or stock dividend or recapitalization;

               (h) any securities issued in a public offering by the Company
pursuant to an effective registration statement filed under the Securities Act;

               (i) any securities issued by the Company in connection with any
acquisition of any business or assets , whether through an asset purchase, share
exchange, merger consolidation or other form of acquisition, in each case, if
approved by the Board; and

               (j) any capital stock issued by an issuer in connection with a
merger in which the Company is not the surviving entity, if approved by the
Board and shareholders of the Company.

          3.3 PROCEDURES. In the event that the Company proposes to undertake an
issuance of New Securities, it shall give to each Rights Holder a written notice
of its intention to issue New Securities (the "NOTICE"), describing the type of
New Securities and the price and the general terms upon which the Company
proposes to issue such New Securities given in accordance with Section 6.1
hereof. Each Rights Holder shall have twenty (20) days from the date such Notice
is effective, as determined pursuant to Section 6.1 hereof based upon the manner
or method of notice, to agree in writing to purchase such Rights Holder's Pro
Rata Share of such New Securities for the price and upon the general terms
specified in the Notice by giving written notice to the Company and stating
therein the quantity of New Securities to be purchased (not to exceed such
Rights Holder's Pro Rata Share). If any Rights Holder fails to so agree in
writing within such twenty (20) day period to purchase such Rights Holder's full
Pro Rata Share of an offering of New Securities (a "NONPURCHASING HOLDER"), then
such Nonpurchasing Holder shall forfeit the right hereunder to purchase that
part of his Pro Rata Share of such New

                                       13
<PAGE>

Securities that he, she or it did not so agree to purchase and the Company shall
promptly give each Rights Holder who has timely agreed to purchase his full Pro
Rata Share of such offering of New Securities (a "PURCHASING HOLDER") written
notice of the failure of any Nonpurchasing Holder to purchase such Nonpurchasing
Rights Holder's full Pro Rata Share of such offering of New Securities (the
"OVERALLOTMENT NOTICE"). Each Purchasing Holder shall have a right of
overallotment such that such Purchasing Holder may agree to purchase a portion
of the Nonpurchasing Holders' unpurchased Pro Rata Shares of such offering on a
pro rata basis according to the relative Pro Rata Shares of the Purchasing
Rights Holders, at any time within ten (10) days after receiving the
Overallotment Notice.

          3.4 FAILURE TO EXERCISE. In the event that the Rights Holders fail to
exercise in full the right of first refusal within such twenty (20) plus ten
(10) day period, then the Company shall have sixty (60) days thereafter to sell
the New Securities with respect to which the Rights Holders' rights of first
refusal hereunder were not exercised, at a price and upon general terms not more
favorable in any respect to the purchasers thereof than specified in the
Company's Notice to the Rights Holders. In the event that the Company has not
issued and sold the New Securities within such sixty (60) day period, then the
Company shall not thereafter issue or sell any New Securities without again
first offering such New Securities to the Rights Holders pursuant to this
Section 3.

          3.5 TERMINATION. This right of first refusal shall terminate on the
earlier of: (i) such time as the Holders hold less than twenty-five percent
(25%) of the Series B Stock initially issued pursuant to the Series B Agreement
(or the Common Stock issued on conversion thereof) or (ii) the seventh
anniversary of this Agreement.

     4. PUBLIC OFFERING PARTICIPATION RIGHTS.

          4.1 PUBLIC OFFERING. In connection with a public offering by the
Company pursuant to an effective registration statement filed under the
Securities Act (a "Public Offering"), the Company shall, within a reasonable
period of time preceding the consummation of the Public Offering, offer each
Holder the opportunity to purchase all or a portion of such Holder's Pro Rata
Share of the securities to be sold in the Public Offering, on the same terms and
conditions on which the securities offered in the Public Offering are being
offered to the public. The foregoing shall apply to each Public Offering
occurring after the date of this Agreement.

          4.2 PRIVATE PLACEMENT. Notwithstanding the foregoing, in the event
that the Company is advised by the SEC, the National Association of Securities
Dealers, Inc., The Nasdaq Stock Market, Inc. or any other regulatory body, or
any of their staffs, that the offering or sale of the such securities to the
Holders as described above in Sections 4.1 is contrary to any federal or state
securities laws or the rules or regulations of the SEC, the National Association
of Securities Dealers, Inc., The Nasdaq Stock Market, Inc. or any other
regulatory body, then the Company shall offer to the Holders the right to
purchase in a separate private placement (which may be conducted, in whole or in
part, concurrently with the Public Offering) a number of the type securities
that are to be issued in the Public Offering that is equal to such Holders' Pro
Rata Share of the number of securities to be issued in the Public Offering, at
the per share public offering price of the securities in such Public Offering
(before excluding underwriters' discounts and commissions).

                                       14
<PAGE>

          4.3 COMPLIANCE. All offers to be made to the Holders under this
Section 4 shall be conducted in compliance with all federal and state securities
laws and regulations, including, without limitation, Rule 134 of the Securities
Act, and all applicable rules, regulations and policies of the SEC, the National
Association of Securities Dealers, Inc., The Nasdaq Stock Market, Inc., any
exchange on which the Company's shares are to be listed, or any other regulatory
body.

          4.4 THIS AGREEMENT NOT AN OFFER. This Agreement does not constitute an
offer to sell securities of the Company. Any offering of the Company's
securities in a Public Offering will only be made pursuant to a prospectus filed
with the SEC.

     5. ASSIGNMENT AND AMENDMENT.

          5.1 ASSIGNMENT. The information rights of a Holder under Section 1
hereof, the registration rights of a Holder under Section 2 hereof, the rights
of first refusal of a Rights Holder under Section 3 hereof, and the Public
Offering participation rights of a Holder under Section 4 hereof may be assigned
only to a party who acquires at least 25,000 shares of Series B Stock and/or
Warrants representing the right to purchase at least 25,000 shares of Common
Stock and/or an equivalent number (on an as-converted basis) of Registrable
Securities issued upon conversion or exercise thereof; provided, however, that,
that any such assignee shall receive such assigned rights subject to all the
terms and conditions of this Agreement, including without limitation the
provisions of this Section 5. Assignments may be made obtaining the minimum
number of shares of Registrable Securities noted above if the assignment is to a
current or retired partner or member, affiliate, shareholder, parent, child or
spouse of the Holder or to the Holder's estate. No assignment of the foregoing
rights shall be deemed to have been made unless expressly evidenced in writing.

          5.2 AMENDMENT AND WAIVER OF RIGHTS. Any provision of this Agreement
may be amended and the observance thereof may be waived (either generally or in
a particular instance and either retroactively or prospectively), only with the
written consent of the Company and Investors (and/or any of their permitted
successors or assigns) holding shares of Series B Stock and/or Conversion Stock
representing and/or convertible into a majority of all the Investors' Shares (as
defined below). Any amendment or waiver effected in accordance with this Section
5.2 shall be binding upon each Investor, each Holder, each permitted successor
or assignee of such Investor or Holder and the Company.

     6. GENERAL PROVISIONS.

          6.1 NOTICES. Any and all notices required or permitted to be given to
a party pursuant to the provisions of this Agreement will be in writing and will
be effective and deemed to provide such party sufficient notice under this
Agreement on the earliest of the following: (i) at the time of personal
delivery, if delivery is in person; (ii) one (1) business day after deposit with
an express overnight courier for United States deliveries, or two (2) business
days after such deposit for deliveries outside of the United States, with proof
of delivery from the courier requested; or (iii) three (3) business days after
deposit in the United States mail by certified mail (return receipt requested)
for United States deliveries.

                                       15
<PAGE>

               All notices for delivery outside the United States will be sent
by express courier. All notices not delivered personally will be sent with
postage and/or other charges prepaid and properly addressed to the party to be
notified at the address as follows, or at such other address as such other party
may designate by one of the indicated means of notice herein to the other
parties hereto as follows:

               (a) if to an Investor, at such Investor's respective address as
set forth on Exhibit A hereto.

               (b) if to the Company, marked "Attention: Chief Executive
Officer", at 3885 Crestwood Parkway, Suite 550, Duluth, GA 30096.

     6.2 ENTIRE AGREEMENT. This Agreement and the documents referred to herein,
together with all the Exhibits hereto, constitute the entire agreement and
understanding of the parties with respect to the subject matter of this
Agreement, and supersede any and all prior understandings and agreements,
whether oral or written, between or among the parties hereto with respect to the
specific subject matter hereof.

     6.3 GOVERNING LAW. This Agreement will be governed by and construed in
accordance with the laws of the State of Delaware, without giving effect to that
body of laws pertaining to conflict of laws.

     6.4 SEVERABILITY. If any provision of this Agreement is determined by any
court or arbitrator of competent jurisdiction to be invalid, illegal or
unenforceable in any respect, such provision will be enforced to the maximum
extent possible given the intent of the parties hereto. If such clause or
provision cannot be so enforced, such provision shall be stricken from this
Agreement and the remainder of this Agreement shall be enforced as if such
invalid, illegal or unenforceable clause or provision had (to the extent not
enforceable) never been contained in this Agreement. Notwithstanding the
forgoing, if the value of this Agreement based upon the substantial benefit of
the bargain for any party is materially impaired, which determination as made by
the presiding court or arbitrator of competent jurisdiction shall be binding,
then both parties agree to substitute such provision(s) through good faith
negotiations.

     6.5 THIRD PARTIES. Nothing in this Agreement, express or implied, is
intended to confer upon any person, other than the parties hereto and their
successors and assigns, any rights or remedies under or by reason of this
Agreement.

     6.6 SUCCESSORS AND ASSIGNS. Subject to the provisions of Section 5.1, this
Agreement, and the rights and obligations of the parties hereunder, will be
binding upon and inure to the benefit of their respective successors, assigns,
heirs, executors, administrators and legal representatives.

     6.7 TITLES AND HEADINGS. The titles, captions and headings of this
Agreement are included for ease of reference only and will be disregarded in
interpreting or construing this Agreement. Unless otherwise specifically stated,
all references herein to "sections" and "exhibits" will mean "sections" and
"exhibits" to this Agreement.

                                       16
<PAGE>

     6.8 COUNTERPARTS. This Agreement may be executed in any number of
counterparts, each of which when so executed and delivered will be deemed an
original, and all of which together shall constitute one and the same agreement.

     6.9 COSTS AND ATTORNEYS' FEES. In the event that any action, suit or other
proceeding is instituted concerning or arising out of this Agreement or any
transaction contemplated hereunder, the prevailing party shall recover all of
such party's costs and attorneys' fees incurred in each such action, suit or
other proceeding, including any and all appeals or petitions therefrom.

     6.10 ADJUSTMENTS FOR STOCK SPLITS, ETC. Wherever in this Agreement there is
a reference to a specific number of shares of Common Stock or Preferred Stock of
the Company of any class or series, then, upon the occurrence of any
subdivision, combination or stock dividend of such class or series of stock, the
specific number of shares so referenced in this Agreement shall automatically be
proportionally adjusted to reflect the affect on the outstanding shares of such
class or series of stock by such subdivision, combination or stock dividend.

     6.11 FURTHER ASSURANCES. The parties agree to execute such further
documents and instruments and to take such further actions as may be reasonably
necessary to carry out the purposes and intent of this Agreement.

We have agreed to the following features of a plan to repay Minnetronix payables
currently carried on ProUroCare's books:

      o     Two-Thirds of accrued interest on the payables will be paid in stock
            of ProUroCare Medical at $2.00 per share conversion. This represents
            $88,882 exchanged for 44,441 shares. The common stock will be
            registered under the current SB-2 filing and is expected to be
            effective in November. At such time, the shares will have no
            restrictions and will be freely tradeable. The balance of interest
            to be paid in cash upfront is $44,441.

      o     25% of outstanding principal shall be paid in cash upfront. This
            amount is $80,538.

      o     The remaining principal balance of $241,613 shall be paid in monthly
            installments on a 6% note over 12 months ($20,794.77/month) or
            within 30 days of closing on a minimum of $2million round of
            financing, whichever is earlier. (SEE ATTACHED NOTE)

      o     A cash deposit of $200,000 shall be made to Minnetronix which shall
            be held in reserve and applied to new development expenses incurred
            from time to time forward. New project expenses incurred shall be
            billed to ProUroCare Inc. and paid monthly with the deposit to be
            applied only if a payment is missed. The balance of the deposit
            shall be applied to the last mutually agreed upon expenses of the
            project.

            If you are in agreement with the terms, please sign and fax back to
me.

                                             $241,613.00
         Principal Amount:
                                             Twelve (12) months
         Term:

         Monthly Payments:                   $20,794.77

         Interest Rate:                      6.0% per annum

INTEREST RATE. Interest shall accrue on the unpaid principal based on 30-day
months and a 360 day year.

PAYMENT TERMS. This Note is due and payable in twelve (12) equal monthly
payments of principal and interest of $20,794.77. The first such payment due and
payable on the 1st day of November, 2004, and a like installment shall be due
and payable on the same day of each succeeding month thereafter until October 1,
2005 (the "Final Scheduled Payment Date").

ACCELERATION OF REPAYMENT. If Borrower closes on a round of financing with gross
proceeds greater than or equal to $2,000,000, the remaining principal balance
and accrued interest thereon shall become due and payable within 30 days of such
closing.

BORROWER'S PRE-PAYMENT RIGHT. Borrower reserves the right to prepay this Note in
whole or in part, prior to maturity, without penalty.

PLACE FOR PAYMENT. Borrower promises to pay to the order of Payee at the place
for payment and according to the terms for payment the principal amount plus
interest at the rates stated above. All unpaid amounts shall be due by the Final
Scheduled Payment Date.

DEFAULT AND ACCELERATION CLAUSE. If Borrower defaults in the payment of this
Note or in the performance of any obligation, and the default continues after
Payee gives Borrower notice of the default and the time within which it must be
cured, as may be required by law or written agreement, then Payee may declare
the unpaid principal balance and earned interest on this Note immediately due.
Borrower and each surety, endorser, and guarantor waive all demands for payment,
presentation for payment, notices of intentions to accelerate maturity, notices
of acceleration of maturity, protests, and notices of protest, to the extent
permitted by law. Failure by Borrower to remit any payment by the 15th day
following the date that such payment is due entitles the Payee hereof to declare
the entire principal and accrued interest immediately due and payable. Payee's
forbearance in enforcing a right or remedy as set forth herein shall not be
deemed a waiver of said right or remedy for a subsequent cause, breach or
default of the Borrower's obligations herein.
