Issuer:  RMD Technologies, Inc.
Class of Stock: Common Stock
Issue Date:  January 27, 2006
Expiration Date:  January 27, 2009

     THIS WARRANT TO PURCHASE COMMON STOCK is being issued pursuant to
that certain Securities Purchase Agreement dated as of the date hereof
(the "Purchase Agreement") between RMD Technologies, Inc., a
California corporation (the "Company") and La Jolla Cove Investors,
Inc. ("Holder").

                               ARTICLE 1
                         DESCRIPTION OF WARRANTS

     1.1  Warrants.  The Company hereby grants to Holder the right
to purchase 10,000,000 shares of the Company's Common Stock (the
"Shares" or "Warrant Shares) at a price per share equal to the
Exercise price set forth in section 2.4 below. Holder will
simultaneously exercise a percentage of this Warrant that is equal to
the percentage of the Debenture being converted. The date that the
Holder issues a Conversion Notice under the Debenture is hereafter
referred to as the "Conversion Date."  Defined terms not defined
herein shall have the meanings ascribed to them in the Debenture or
the Securities Purchase Agreement.

     1.2  Requirement to Exercise.  Holder agrees that, beginning
in the first full calendar month after the Registration Statement is
declared effective, Holder will exercise at least 5% of the Warrants
per calendar month, provided that the Common Shares are available,
registered and freely tradable. If Holder exercises more than 5% of
the Warrants in any calendar month, the excess over 5% shall be
credited against the next month's minimum exercise amount. In the
event Holder does not exercise at least 5% of the Warrants in any
particular calendar month, Holder shall not be entitled to collect
interest on the Debenture for that month if the Company gives Holder
written notice, at least 5 business days prior to the end of the
month, of Holder's failure to exercise the minimum required amount for
that month.

     1.3  Expiration of Warrants.  This Warrant shall expire and
Holder shall no longer be able to purchase the Warrant Shares on the
Expiration Date.

                                ARTICLE 2
                                 EXERCISE

     2.1  Method of Exercise.  Holder may exercise this Warrant by
delivering a duly executed Warrant Notice of Exercise in substantially
the form attached as Appendix 1 to the principal office of the Company.

     2.2  Delivery of Certificate and New Warrant.  As promptly as
practicable after the receipt of the Warrant Notice of Exercise, but
in any event not more than two (2) Business Days after the Company's
receipt of the Warrant Notice of Exercise, the Company shall issue the
Shares and cause to be mailed for delivery by overnight courier, or if
a Registration Statement covering the Shares has been declared
effective by the SEC cause to be electronically transferred, to Holder
a certificate representing the Shares acquired and, if this Warrant
has not been fully exercised and has not expired, a new Warrant
substantially in the form of this Warrant representing the right to
acquire the portion of the Shares not so acquired.

     2.3  Replacement of Warrants.  On receipt of evidence
reasonably satisfactory to the Company of the loss, theft, destruction
or mutilation of this Warrant and, in the case of loss, theft or
destruction, on delivery of an indemnity agreement reasonably
satisfactory in form and amount to the Company or, in the case of
mutilation, or surrender and cancellation of this Warrant, the Company
at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

     2.4  Exercise Price.  The Exercise Price of this Warrant shall
be $1.00 per Share.

     2.5  Certain Exercise Limits.  For a period of one year after the
Closing Date, if and to the extent that, on any date, the holding by
the Holder of this Warrant would result in the Holder's being deemed
the beneficial owner of more than 9.9% of the then Outstanding shares
of Common Stock, then the Holder shall not have the right, and the
Company shall not have the obligation, to exercise any portion of this
Warrant, as shall cause Holder to be deemed the beneficial owner of
more than 9.9% of the then Outstanding shares of Common Stock.

                              ARTICLE 3
                       ADJUSTMENT TO THE SHARES

     The number of Shares purchasable upon the exercise of this
Warrant and the Exercise Price shall be subject to adjustment from
time to time upon the occurrence of certain events, as follows:

     3.1  Reclassification.  In case of any reclassification or
change of outstanding securities of the class issuable upon exercise
of this Warrant then, and in any such case, the Holder, upon the
exercise hereof at any time after the consummation of such
reclassification or change, shall be entitled to receive in lieu of
each Share theretofore issuable upon exercise of this Warrant, the
kind and amount of shares of stock, other securities, money and/or
property received upon such reclassification or change by a holder of
one Share.  The provisions of this Section 3.1 shall similarly apply
to successive reclassifications or changes.

     3.2  Subdivision or Combination of Shares.  If the Company at
any time while this Warrant remains outstanding and unexpired shall
subdivide or combine its Shares, the Exercise Price shall be
proportionately decreased in the case of a subdivision or increased in
the case of a combination.

     3.3  Stock Dividends.  If the Company, at any time while this
Warrant is outstanding shall pay a dividend with respect to its Shares
payable in Shares, or make any other distribution of Shares with
respect to Shares (except any distribution specifically provided for
in Section 3.1 and Section 3.2 above), then the Exercise Price shall
be adjusted, effective from and after the date of determination of
shareholders entitled to received such dividend or distribution, to
that price determined by multiplying the Exercise Price in effect
immediately prior to such date of determination by a fraction, (a) the
numerator of which shall be the total number of Shares outstanding
immediately prior to such dividend or distribution, and (b) the
denominator of which shall be the total number of Shares outstanding
immediately after such dividend or distribution.

     3.4  Non-Cash Dividends.  If the Company at any time while this
Warrant is outstanding shall pay a dividend with respect to Shares
payable in securities other than Shares or other non-cash property, or
make any other distribution of such securities or property with
respect to Shares (except any distribution specifically provided for
in Section 3.1 and Section 3.2 above), then this Warrant shall
represent the right to acquire upon exercise of this Warrant such
securities or property which a holder of Shares would have been
entitled to receive upon such dividend or distribution, without the
payment by the Holder of any additional consideration for such
securities or property.

     3.5  Effect of Reorganization and Asset Sales.  If any (i)
reorganization or reclassification of the Common Stock (ii)
consolidation or merger of the Company with or into another
corporation, or (iii) sale or all or substantially all of the
Company's operating assets to another corporation followed by a
liquidation of the Company (any such transaction shall be referred to
herein as an "Event"), is effected in such a way that holders of
common Stock are  entitled to receive securities and/or assets as a
result of their Common Stock ownership, the Holder, upon exercise of
this Warrant, shall be entitled to receive such shares of stock
securities or assets which the Holder would have received had it fully
exercised this Warrant on or prior the record date for such Event.
The Company shall not merge into or consolidate with another
corporation or sell all of its assets to another corporation for a
consideration consisting primarily of securities of such corporation,
unless the successor or acquiring corporation, as the case may be,
shall expressly assume the due and punctual observance and performance
of each and every covenant and condition of this Warrant to be
performed or observed by the Company and all of the obligations and
liabilities hereunder, subject to such modification as shall be
necessary to provide for adjustments which shall be as nearly
equivalent as practicable to the adjustments provided for in this
Section 2.  The foregoing provisions shall similarly apply to
successive mergers, consolidations or sales of assets.

     3.6  Adjustment of Number of Shares.  Upon each adjustment in
the Exercise Price, the number of Shares shall be adjusted, to the
nearest whole share, to the product obtained by multiplying the number
of Shares, purchasable immediately prior to such adjustment by a
fraction, the numerator of which shall be the Exercise Price
immediately prior to such adjustment and the denominator of which
shall be the Exercise Price immediately thereafter.

     3.7  No Impairment.  The Company shall not, by amendment of its
articles of incorporation or through a reorganization, transfer of
assets, consolidation, merger, dissolution, issue, or sale of
securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms to be observed or
performed under this Warrant by the Company, but shall at all times in
good faith assist in carrying out all of the provisions of this
Warrant and in taking all such action as may be reasonably necessary
or appropriate to protect Holder's rights hereunder against
impairment.  If the Company takes any action affecting its Common
Stock other than as described above that adversely affects Holder's
rights under this Warrant, the Exercise Price shall be adjusted
downward and the number of Shares issuable upon exercise of this
Warrant shall be adjusted upward in such a manner that the aggregate
Exercise Price of this Warrant is unchanged.

     3.8  Fractional Shares.  No fractional Shares shall be issuable
upon the exercise of this Warrant, and the number of Shares to be
issued shall be rounded down to the nearest whole Share.

     3.9  Certificate as to Adjustments.  Upon any adjustment of the
Exercise Price, the Company, at its expense, shall compute such
adjustment and furnish Holder with a certificate of its Chief
Financial Officer setting forth such adjustment and the facts upon
which such adjustment is based.  The Company shall, upon written
request, furnish Holder a certificate setting forth the Exercise Price
in effect upon the date thereof and the series of adjustments leading
to such Exercise Price.

     3.10  No Rights of Shareholders.  This Warrant does not entitle
Holder to any voting rights or any other rights as a shareholder of
the Company prior to the exercise of Holder's right to purchase Shares
as provided herein.

                               ARTICLE 4
             REPRESENTATIONS AND COVENANTS OF THE COMPANY

     4.1  Representations and Warranties.  The Company hereby
represents and warrants to Holder that all Shares which may be issued
upon the exercise of the purchase right represented by this Warrant,
shall, upon issuance, be duly authorized, validly issued, fully paid
and nonasessable, and free of any liens and encumbrances.

     4.2  Notice of Certain Events.  If the Company proposes at any
time (a) to declare any dividend or distribution upon its Common
Stock, whether in cash, property, stock, or other securities and
whether or not a regular cash dividend; (b) to offer for subscription
pro rata to the holders of any class or series of its stock any
additional shares of stock of any class or series or other rights; (c)
to effect any reclassification or recapitalization of Common Stock;
(d) to merge or consolidate with or into any other corporation, or
sell, lease, license, or convey all or substantially all of its
assets, or to liquidate, dissolve or wind up; or (e) offer holders of
registration rights the opportunity to participate in an underwritten
public offering of the Company's securities for cash, then, in
connection with each such event, the Company shall give Holder (1) at
least 20 days prior written notice of the date on which a record will
be taken for such dividend, distribution, or subscription rights (and
specifying the date on which the holders of Common Stock will be
entitled thereto) or for determining rights to vote, if any, in
respect of the matters referred to in (c) and (d) above; (2) in the
case of the matters referred to in (c) and (d) above at least 20 days
prior written notice of the date when the same will take place (and
specifying the date on which the holders of Common Stock will be
entitled to exchange their Common Stock for securities or other
property deliverable upon the occurrence of such event); and (3) in
the case of the matter referred to in (e) above, the same notice as is
given to the holders of such registration rights.

     4.3  Information Rights.  So long as Holder holds this Warrant
and/or any of the Shares, the Company shall deliver to Holder (a)
promptly after mailing, copies of all notices or other written
communications to the shareholders of the Company, (b) within ninety
(90) days of their availability, the annual audited financial
statements of the Company certified by independent public accountants
of recognized standing, and (c) within forty-five (45) days after the
end of each fiscal quarter or each fiscal year, the Company's
quarterly, unaudited financial statements.

     4.4  Reservation of Warrant Shares.  The Company has reserved
and will keep available, out of the authorized and unissued shares of
Common Stock, the full number of shares sufficient to provide for the
exercise of the rights of purchase represented by this Warrant.

     4.5  Registration Rights. If Holder exercises this Warrant and
purchases some or all of the Shares, Holder shall have the
Registration Rights set forth in that certain Registration Rights
Agreement executed concurrently therewith.

                               ARTICLE 5
           REPRESENTATIONS AND COVENANTS OF THE HOLDER

     5.1  Private Issue.  Holder understands (i) that the Shares
issuable upon exercise of Holder's rights contained in the Warrant are
not registered under the Act or qualified under applicable state
securities laws on the ground that the issuance contemplated by the
Warrant will be exempt from the registration and qualifications
requirements thereof, and (ii) that the Company's reliance on such
exemption is predicated on Holder's representations set forth in this
Article 5.

     5.2  Financial Risk.  Holder has such knowledge and experience
in financial and business matters as to be capable of evaluating the
merits and risks of its investment and has the ability to bear the
economic risks of its investment.

     5.3  Risk of No Registration.  Holder understands that if the
Company does not register with the Securities and Exchange Commission
pursuant to Section 12 of the Act, or file reports pursuant to Section
15(d), of the Securities Exchange Act of 1934 (the "1934 Act"), or if
a registration statement covering the securities under the Act is not
in effect when it desires to sell (i) the right to purchase Shares
pursuant to the Warrant, or (ii) the Shares issuable upon exercise of
the right to purchase, it may be required to hold such securities for
an indefinite period.

     5.4  Accredited Investor.  Holder is an "accredited investor,"
as such term is defined in Regulation D promulgated pursuant to the Act.

                               ARTICLE 6

reasonably satisfactory to the Company, as reasonably requested by the
Company). The Company shall not require Holder to provide an opinion
of counsel if the transfer is to an affiliate of Holder.

     6.3  Transfer Procedure.  Holder shall have the right without
the consent of the Company to transfer or assign in whole or in part
this Warrant and the Shares issuable upon exercise of this Warrant.
Holder agrees that unless there is in effect a registration statement
under the Act covering the proposed transfer of all or part of this
Warrant, prior to any such proposed transfer the Holder shall give

proposed transfer in reasonable detail and, if the company so
requests, shall be accompanied by an opinion of legal counsel, in a

provided that the Company will not require opinions of counsel for
transactions involving transfers to affiliates or pursuant to Rule 144
promulgated by the Securities and Exchange Commission under the act,
except in unusual circumstances.

in addition to the penalties assessable herein, to an injunction or
injunctions restraining, preventing or curing any breach of this
Warrant and to enforce specifically the terms and provisions hereof,
