the date set forth on the signature page hereof by and between InforMedix
Holdings, Inc. a Nevada corporation (the "Company"), and the undersigned

      In consideration of the mutual representations, warranties, covenants and
agreements contained herein and for other good and valuable consideration, the
receipt and adequacy of which are hereby acknowledged, the parties hereto agree
as follows:

                                    ARTICLE I
                              TERMS OF THE OFFERING

      1.8   The Company is offering (the "Offering") to the undersigned Investor
            and all other existing holders of Warrants ("MA Warrants")
            originally issued to Meyers Associates, L.P. ("MA"), in connection
            with the 2004 Private Placement of the Company's securities
            ("Warrantholders") shares of Common Stock, $.001 par value ("Common
            Stock") of the Company. The Offering shall terminate at 11:59 p.m.
            Eastern Time on February 24, 2005 (the "Termination Date"), unless
            mutually extended by the Company and Meyers Associates L.P., its
            financial consultant and advisor. The Offering is being made only to
            Investors who qualify as "accredited investors" as such term is
            defined in Rule 501 of Regulation D under the Securities Act of
            1933, as amended (the "Securities Act"). The shares of Common Stock
            issuable upon the exchange of the MA Warrants are collectively
            referred to herein as the "Securities."

            Subject to the terms and conditions of this Agreement, the Investor
            desires to exchange (the "Exchange Offer") all MA Warrants owned by
            the Investor and the Company desires to issue to the Investor, the
            number of shares of Common Stock set forth upon the signature page
            hereof (the "Securities") at an exchange rate (the "Exchange Rate")
            set forth therein, and on the other terms and conditions set forth
            in this Agreement.

      1.9   The undersigned, Investor intending to be legally bound, hereby
            irrevocably subscribes to exchange all MA Warrants owned by the
            Investor as set forth on the signature page hereof, as calculated
            below, for Shares of Common Stock equal to 45% of the shares of
            Common Stock otherwise issuable upon exercise of the MA Warrants
            currently held by the Investor. By way of example, each Unit
            issuable upon exercise of the MA Warrants consists of 135,136 shares
            of Common Stock, Class A Warrants to purchase 135,136 shares of
            Common Stock and Class B Warrants to purchase 67,568 shares of
            Common Stock, or an aggregate of 337,840 shares of Common Stock per
            Unit multiplied by 45%, or an Exchange Rate of 152,028 shares of
            Common Stock issuable for each Unit issuable upon exercise of the MA
            Warrants. Investors will only be eligible to participate in this
            offering to the extent that they surrender 100% of all MA Warrants
            held. This Offering will be made on a "best efforts" basis. However,
            at least 70% of all of MA Warrants must be exchanged before there
            will be a Closing. However, there shall be no partial participation.
            Investors that hold fractional units shall be permitted to
            participate proportionately by multiplying the respective numbers
            for one full Unit by the fraction held.

      1.10  An executed and properly completed copy of this Agreement together
            with the other documents set forth above under "Subscription
            Instructions" should be delivered, to Meyers Associates, L.P.
            ("MA"), 45 Broadway, New York, New York 10006, Attention: Bruce
            Meyers.

      1.11  If this Agreement is accepted by the Company, in whole or in part,
            and subject to the conditions set forth in Section 2.2 of this
            Agreement, the Company shall issue the Common Stock subscribed for
            hereby, dated the date of closing of the Offering of such Agreement

<PAGE>

            (the "Closing") and return to the Investor a fully executed copy of
            this Agreement. The Investor hereby authorizes and directs the
            Company to deliver certificates representing the Securities to be
            issued to such Investor pursuant to this Agreement to the Escrow
            Agent unless otherwise notified by the Investor that he is
            exercising his registration rights.

      1.12  The undersigned may not withdraw this subscription or any amount,
            paid pursuant thereto, except as otherwise provided below.

      1.13  If the Investor is not a United States person, such Investor hereby
            represents that it has satisfied itself as to the full observance of
            the laws of its jurisdiction in connection with any invitation to
            subscribe for the Securities or any use of this Agreement, including
            (i) the legal requirements within its jurisdiction for the purchase
            of the Securities, (ii) any foreign exchange restrictions applicable
            to such purchase, (iii) any governmental or other consents that may
            need to be obtained, and (iv) the income tax and other tax
            consequences, if any, that may be relevant to the purchase, holding,
            redemption, sale or transfer of the Securities. Such Investor's
            subscription and payment for, and his or her continued beneficial
            ownership of the Securities, will not violate any applicable
            securities or other laws of the Investor's jurisdiction.


                                   ARTICLE II
                              EXCHANGE OF WARRANTS

      In consideration of the mutual promises contained herein and other good
and valuable consideration, receipt of which is hereby acknowledged, the parties
of this Agreement agree as follows:

      2.4   Exchange Offer. Subject to the terms and conditions of this
            Agreement:

            (v)   Each Investor agrees to purchase at the Closing (as defined
                  below) and the Company agrees to sell and issue to each
                  Investor at the Closing that aggregate number of shares of
                  Common Stock set forth opposite such Investor's name on the
                  signature page hereof as shall be equal to 45% of the shares
                  of Common Stock underlying all MA Warrants held by the
                  undersigned Investor. An Investor will only be eligible to
                  participate in this Offering to the extent he exchanges 100%
                  of all MA Warrants owned. There shall be no partial exchange
                  of MA Warrants. Investors that hold fractional MA Warrants
                  shall be permitted to participate proportionately.

            (vi)  Upon the Exchange Offer and the Closing occurring, the shares
                  of Common Stock issued shall be delivered to the Company's
                  Securities Counsel, Robinson & Cole LLP to act as escrow agent
                  (the "Escrow Agent"). These shares have been previously
                  registered with the Securities and Exchange Commission (the
                  "SEC"). However, these shares will only become free trading
                  upon filing of a new registration statement (the "Registration
                  Statement"), describing this Offering, which the Company shall
                  do within ten days of the Closing. These shares of Common
                  Stock held in escrow shall be released upon the effective date
                  of the registration statement or sooner if the Investor
                  request such shares and waives his registration rights and
                  elects to receive restricted Common Stock.

            (vii) The undersigned agrees to forfeit all rights, title and
                  interest to, and surrender all MA Warrants owned, in exchange
                  for the Securities set forth in subparagraph (i) above.

            (viii) By way of example, for each MA Warrant issued pursuant to the
                  InforMedix Private Placement Memorandum dated October 20, 2003
                  ("2003-2004 InforMedix Private Placement"), an Investor
                  received a warrant to purchase 135,136 shares of common stock,
                  135,136 Class A Warrants exercisable into 135,136 shares of
                  common stock at $.44 per share, and 135,136 Class B Warrants

<PAGE>

                  exercisable into 67,568 shares of common stock at $.56 per
                  share. Under the terms of this Agreement, an Investor holding
                  one MA Warrant to purchase one Unit consisting of an aggregate
                  of 337,840 shares of Common Stock would surrender his MA
                  Warrant and the Company would issue the Investor an aggregate
                  of 152,028 shares of restricted common stock (the
                  "Securities") as consideration for the Exchange Rate for one
                  MA Warrant. All shares of restricted Common Stock shall be
                  delivered to the Escrow Agent and held in escrow until
                  registered on the Registration Statement as described in
                  Article VII below.

      2.5   Conditions of Offering. It is understood and agreed that this
            Agreement is made subject to the following terms and conditions:

            (v)   The Company and MA shall have the right to accept or reject
                  this Agreement in whole. Unless this subscription is accepted
                  in whole by the Company prior to the Termination Date, this
                  Agreement shall be deemed rejected in whole. Agreements
                  accepted in whole by the Company shall be irrevocable, except
                  as otherwise provided by law. Agreements need not be accepted
                  in the order received.

            (vi)  At the date of the Closing, MA shall have been furnished with
                  such information, documents, certificates, and opinions as it
                  may reasonably require to evidence the accuracy, completeness,
                  or satisfaction of the representations, warranties, covenants,
                  agreements, and conditions herein contained or as it otherwise
                  may reasonably request.

            (vii) The Investor acknowledges that the Company may, in its sole
                  and absolute discretion, reduce the Investor's Exchange Offer
                  for Securities to any number of MA Warrants that does not
                  exceed the number of MA Warrants set forth on the signature
                  page hereof, or that the Company may reject the Investor's
                  subscription in its entirety, in each case without prior
                  notice to or consent by the Investor. Upon acceptance of the
                  Investor's Exchange Offer for Securities, the Company shall
                  issue the Securities to the Investor at the Exchange Rate,
                  subject to the terms and conditions of this Agreement. The
                  Closing of the Offering is set forth in Section 2.3 hereof.
                  The Company and the Investor shall each bear their own
                  expenses in connection with the Offering.

            (viii) The Company and the Investors agree that warrant exchanges by
                  officers, directors, their affiliates and other insiders may
                  be made in this Offering.

      2.6   Closing; Deliver.

            (iv)  The "Closing" shall mean such date, after all the conditions
                  precedent in Section 2.2 and Article V are fulfilled or waived
                  in writing, as the case may be, prior to the Termination Date
                  (the "Initial Closing"). On each Closing, exchange of the
                  Warrants shall take place at such time and place as the
                  Company and the Investors mutually agree upon, orally or in
                  writing. The Investors shall not be liable to any party,
                  including, but not limited to, the Company, in the event any
                  Closing does not take place owing to the conditions set out in
                  Section 2.2 and Article V not being fulfilled or waived as the
                  case may be.

            (v)   At each Closing, the Company shall deliver to the Escrow Agent
                  the relevant Securities to be purchased by each Investor at
                  the Closing against delivery of counterpart signature pages to
                  this Agreement and the relevant MA Warrant Certificate, with
                  the executed Assignment Form.

            (vi)  The Securities will be delivered to the Escrow Agent
                  simultaneously with each Closing unless contrary instructions
                  are received form the Investor and the Company. As described
                  in Section 2.1 above, the Securities will be held in escrow
                  with the Escrow Agent until such time as the shares of Common
                  stock are registered on the Registration Statement.
                  Notwithstanding the foregoing, at any time an Investor may
                  elect to waive his registration rights and receive his

<PAGE>

                  securities from the Company or the Escrow Agent. Delivery of
                  the Securities to be issued to each Investor shall be made by
                  the Company following the effective date of the applicable
                  Registration Statement by delivery to the Investor of
                  certificates for the total number of Securities to be issued
                  to the Investor hereunder registered in the name of the
                  Investor or such other person as the Investor may have
                  designated. This Agreement shall terminate and be of no
                  further force and effect if the Initial Closing does not occur
                  on or before February 25, 2005 unless extended by mutual
                  consent of the Company and MA.


                                   ARTICLE III
                   REPRESENTATION AND WARRANTIES OF INVESTORS

           Each Investor represents and warrants to the Company that:

      3.26  Such Investor has full power and authority to enter into this
            Agreement. This Agreement, when executed and delivered by the
            Investor, will constitute a valid and legally binding obligation of
            the Investor, enforceable in accordance with its terms, except as
            limited by applicable bankruptcy, insolvency, reorganization,
            moratorium, fraudulent conveyance, and any other laws of general
            application affecting enforcement of creditors' rights generally,
            and as limited by laws relating to the availability of a specific
            performance, injunctive relief, or other equitable remedies.

      3.27  This Agreement is made with the Investor in reliance upon the
            Investor's representation to the Company, which by the Investor's
            execution of this Agreement, the Investor hereby confirms, that the
            Securities to be acquired by the Investor will be acquired for
            investment for the Investor's own account, not as a nominee or
            agent, and not with a view to the resale or distribution of any part
            thereof as at the date of this Agreement, and that the Investor has
            no present intention of selling, granting any participation in, or
            otherwise distributing the same. By executing this Agreement, the
            Investor further represents that the Investor does not presently
            have any contract, undertaking, agreement or arrangement with any
            person to sell, transfer or grant participations to such person or
            to any third person, with respect to any of the Securities. The
            Investor has not been formed for the specific purpose of acquiring
            any of the Securities.

      3.28  The Investor acknowledges receipt and careful review of this
            Agreement and all exhibits thereto and other documents furnished in
            connection with this transaction (collectively, the "Offering
            Documents") and hereby represents that he has been furnished by the
            Company during the course of this transaction with all information
            regarding the Company which he has requested or desires to know; and
            that such information and documents have, in his opinion, afforded
            the Investor with all of the same information that would be provided
            him in a registration statement filed under the Act; that he has
            been afforded the opportunity to ask questions of and receive
            answers from duly authorized officers or other representatives of
            the Company concerning the terms and conditions of the offering, and
            any additional information which he had requested.

      3.29  The Investor recognizes that the purchase of Securities involves a
            high degree of risk in that (i) an investment in the Company is
            highly speculative and only Investors who can afford the loss of
            their entire investment should consider investing in the Company and
            the Securities; (ii) he may not be able to liquidate his investment;
            (iii) transferability of the Securities is extremely limited; and
            (iv) an Investor could suffer the loss of his entire investment, as
            well as other risk factors as more fully set forth herein.

      3.30  The Investor represents and warrants that he is still an "accredited
            investor" as such term in defined in Rule 501 of Regulation D
            promulgated under the Act, as indicated by his prior responses to
            the Purchaser Questionnaire and Statement ("Purchaser
            Questionnaire"), and that he is able to bear the economic risk of an
            investment in the Securities. The Investor further represents and
            warrants that the information furnished in the Purchaser
            Questionnaire remains accurate and complete in all material
            respects.

<PAGE>

      3.31  The Investor acknowledges that he has prior investment experience,
            including investment in non-listed and non-registered securities, or
            he has employed the services of an investment advisor, attorney or
            accountant to read all of the documents furnished or made available
            by the Company both to him and to all other prospective Investors in
            the Securities and to evaluate the merits and risks of such an
            investment on his behalf, and that he recognizes the highly
            speculative nature of this investment.

      3.32  The Investor acknowledges that this offering of Securities may
            involve tax consequences and that the contents of the Offering
            Documents do not contain tax advice or information. The Investor
            acknowledges that he must retain his own professional advisors to
            evaluate the tax and other consequences of an investment in the
            Securities. The Investor acknowledges that he has had an opportunity
            to consult with counsel of his choice and that he must retain his
            own legal advisor. The Investor has not relied on the Company, it
            officers, directors, or professional advisors for advise as to such
            consequences.

      3.33  The Investor acknowledges that this Offering has not been reviewed
            by the SEC because of the Company's representations that this is
            intended to be a nonpublic offering pursuant to Sections 4(2), 4(6)
            or 3(b) of the Act and Rule 506 of Regulation D promulgated
            thereunder. The Investor represents that the Securities are is being
            purchased for his own account, for investment and not with a view
            to, or for resale in connection with, their distribution within the
            meaning of the Act. The Investor agrees that he will not sell or
            otherwise transfer the Securities unless it is registered under the
            Act or unless an exemption from such registration is available.

      3.34  The Investor understands that, except as set forth in Article VII,
            the Securities have not been, and will not be, registered under the
            Act, by reason of a specific exemption from the registration
            provisions of the Act which depends upon, among other things, the
            bona fide nature of the investment intent and the accuracy of the
            Investor's representations as expressed herein. In this connection,
            the Investor understands that it is the position of the SEC that the
            statutory basis for such exemption would not be present if his
            representation merely meant that his present intention was to hold
            such securities for a short period, such as the capital gains period
            of tax statutes, for a deferred sale, for a market rise, assuming
            that a market develops, or for any other fixed period. The Investor
            realizes that, in the view of the SEC, a purchase now with an intent
            to resell would represent a purchase with an intent inconsistent
            with his representation to the Company, and the SEC might regard
            such a sale or disposition as a deferred sale to which such
            exemptions are not available.

            The Investor understands that the Securities are "restricted
            securities" under applicable U.S. federal and state securities laws
            and that, pursuant to these laws, the Investor must hold the
            Securities indefinitely unless they are registered with the SEC and
            qualified by state authorities, or an exemption from such
            registration and qualification requirements is available. The
            Investor acknowledges that the Company has no obligation to register
            or qualify the Securities for resale other than as set forth in
            Article VII herein and as set forth in Exhibit V attached hereto.
            The Investor further acknowledges that if an exemption from
            registration or qualification is available, it may be conditioned on
            various requirements including, but not limited to, the time and
            manner of sale, the holding period for the Securities, and on
            requirements relating to the Company which are outside of the
            Investor's control, and which the Company is under no obligation and
            may not be able to satisfy.

      3.35  The Investor understands that no public market now exists for the
            Warrants and only a limited market for the underlying Common Stock.

      3.36  The Investor understands that the Securities, and any securities
            issued in respect thereof or exchange therefor, may bear one or all
            of the following legends:

<PAGE>

            (i) "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
            REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN ACQUIRED
            FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE
            SALE OR DISTRIBUTION THEREOF. NO SUCH SALE OR DISTRIBUTION MAY BE
            EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO
            OR AN OPINION OF COUNSEL IN A FORM SATISFACTORY TO THE COMPANY THAT
            SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933."

            (ii) Any legend required by the Blue Sky laws of any state to the
            extent such laws are applicable to the shares represented by the
            certificate so legended.

      3.37  The Investor understands that Rule 144 ("Rule 144") promulgated
            under the Act requires, among other conditions, a one-year holding
            period prior to the resale (in limited amounts) of securities
            acquired in a non-public offering without having to satisfy the
            registration requirements under the Act. The Investor understands
            that the Company makes no representation or warranty regarding its
            fulfillment in the future of any reporting requirements under the
            Securities Exchange Act of 1934, as amended (the "Exchange Act"), or
            its dissemination to the public of any current financial or other
            information concerning the Company, as is required by Rule 144 as
            one of the conditions of its availability. The Investor understands
            and hereby acknowledges that the Company is under no obligation to
            register the Securities under the Act, with the exception of certain
            registration rights set forth in Article VII herein. The Investor
            consents that the Company may, if it desires, permit the transfer of
            the Securities out of his name only when his request for transfer is
            accompanied by an opinion of counsel reasonably satisfactory to the
            Company that neither the sale nor the proposed transfer results in a
            violation of the Act or any applicable state "blue sky" laws
            (collectively "Securities Laws"). The Investor agrees to hold the
            Company and its directors, officers and controlling persons and
            their respective heirs, representatives, successors and assigns
            harmless and to indemnify them against all liabilities, costs and
            expenses incurred by them as a result of any misrepresentation made
            by him contained herein or in the Purchaser Questionnaire or any
            sale or distribution by the undersigned Investor in violation of any
            Securities Laws.

      3.38  The Investor understands that the Company will review this Agreement
            and the Purchaser Questionnaire and otherwise review the financial
            standing of the Investor, and it is agreed that the Company reserves
            the unrestricted right to reject or limit any subscription.

      3.39  The Investor hereby represents that the address of Investor
            furnished by him at the end of this Agreement is the undersigned's
            principal residence if he is an individual or its principal business

            the Investor is at least 21 years of age and legally competent to
            execute this Agreement.

      3.40  The Investor acknowledges that if he is a Registered Representative
            of an NASD member firm, he must give such firm the notice required
            by the NASD's Rules of Fair Practice, receipt of which must be
            acknowledged by such firm on the signature page hereof.

      3.41  The Investor acknowledges that at such time, if ever, as the
            Securities are registered, sales of such securities will be subject
            to state securities laws, including those of states which may
            require any securities sold therein to be sold through a registered
            broker-dealer or in reliance upon an exemption from registration.

      3.42  Investor hereby agrees that prior to the Closing Date of this
            Offering, he will not sell short any shares of the Company's Common
            Stock or otherwise sell any shares of the Company's Common Stock

            consummated by the delivery of the Company's shares borrowed by or
            from the Investor or his affiliates.

                                   ARTICLE IV
                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

            The Company hereby represents and warrants to each Investor on the
            date hereof and at the Closing Date. The Company is a corporation
            duly organized, validly existing and in good standing under the laws
            of the State of Nevada and has all requisite corporate power and

<PAGE>

            authority to carry on its business as now conducted and as proposed
            to be conducted. The Company is duly qualified to transact business
            and is in good standing in each jurisdiction in which the failure so
            to qualify would have a material adverse effect on its business or
            properties.

      4.10  This Agreement, the Registration Rights Agreement, the Warrants, and
            the stock issuable upon exchange of the Warrants, have been duly
            authorized by the Board of Directors of the Company and its
            shareholders. This Agreement and the Registration Rights Agreement,
            shall constitute valid and legally binding obligations of the
            Company, enforceable against the Company in accordance with their
            respective terms except as limited by applicable bankruptcy,
            insolvency, reorganization, moratorium, fraudulent conveyance, and
            other laws of general application affecting enforcement of
            creditors' rights generally, and as limited by laws relating to the
            availability of specific performance, injunctive relief, or other
            equitable remedies. 4.11 The execution, delivery and performance of
            this Agreement by the Company will have been duly approved by the
            Board of Directors of the Company and all other actions required to
            authorize and effect the offer and sale of the Securities contained
            herein will have been duly taken and approved.

      4.12  The Securities have been duly and validly authorized and when issued
            and paid for in accordance with the terms hereof, will be duly and
            validly issued, fully paid and non-assessable and will not be issued
            in violation of any preemptive or other rights of stockholders known
            to the Company except that with respect to any Warrants not
            exchanged the Company makes no representation or warranty as to the
            effect of this Offering on the anti-dilution provisions of the
            currently issued and outstanding Warrants.

      4.13  The Company has obtained, or is in the process of obtaining, all
            licenses, permits and other governmental authorizations necessary to
            the conduct of its business; such licenses, permits and other
            governmental authorizations obtained are in full force and effect;
            and the Company is in all material respects complying therewith.

      4.14  The Company knows of no pending or threatened legal or governmental
            proceedings to which the Company is a party, which could materially
            adversely affect the business, property, financial condition or
            operations of the Company.

      4.15  The Company is not in violation of or default under, nor will the
            execution and delivery of this Agreement, the issuance of the
            Securities, and the incurrence of the obligations herein and therein
            set forth and the consummation of the transactions herein or therein
            contemplated, result in a violation of, or constitute a default
            under, the Company's articles of incorporation or by-laws, any
            material obligations, agreement, covenant or condition contained in
            any bond, debenture, note or other evidence of indebtedness or in
            any material contract, indenture, mortgage, loan agreement, lease,
            joint venture or other agreement or instrument to which the Company
            is a party or by which it or any of its properties may be bound or
            any material order, rule, regulation, writ, injunction, or decree of
            any government, governmental instrumentality or court, domestic or
            foreign. 4.16 The authorized capital stock of the Company consists
            of 4,500,000 shares of preferred stock, par value $.001 per share
            (the "Preferred Stock"), and 80,000,000 shares of Common Stock, par
            value $.001 per share. There are no outstanding shares of Preferred
            Stock. Each outstanding share of Common Stock is duly authorized,
            validly issued, fully paid and non assessable. Except as set forth
            in the Company's filings with the SEC there are no options, warrants
            or other derivative securities, voting trusts or other agreements or
            understandings to which the Company is a party with respect to the
            transfer, voting, issuance, purchase, redemption, repurchase or
            registration of the capital stock of the Company. The Company does
            not own or have any contract to acquire, any equity securities or
            other securities of any person or any, direct or indirect, equity or
            ownership interest in any other business.

      4.17  Except for a Form D filing with the SEC and any required blue sky
            filings, no consent, authorization, approval, order, license,
            certificate or permit of or from, or declaration or filing with, any

            are subject is required for the execution, delivery or performance
            by the Company of this Agreement, or the execution, issuance, sale

                                  ARTICLE VIII

                                  RISK FACTORS

An investment in the securities offered hereby is highly speculative and
involves a high degree of risk and should be made only by investors who can
afford to lose their entire investment. Prospective Investors, prior to making
any investment decision should carefully consider along with other matters
referred to herein the following risk factors.

Risks Relating to Our Financial Condition

Need for proceeds of this Offering.

As of December 20, 2004, we had cash of approximately $15,000 on hand.
Subsequent thereof, we raised approximately $454,000 for the exchange offer with
investors in our 2004 Private Placement for which the MA Warrants were issued.
We require the proceeds from the Exercise Offer plus additional financing to
implement the stated business plan attached as Exhibit A to this Memorandum.
Management can give no assurance that we will obtain sufficient funds to fully
implement the business plan, or that implementation of such business plan will
result in InforMedix's profitability. If we are unable to complete other
financing, we may have to curtail or suspend our operations, and you could lose
your entire investment in our company.

If InforMedix continues to incur negative cash flow from its operations, it may
exhaust our capital resources.

No net positive cash flow has been generated from InforMedix's operations since
its inception. InforMedix has been primarily a development stage company, to
date, and has invested the majority of its resources in the R&D of the product
and its patents, with minimal investment for the commercialization of its
product. InforMedix had a net loss of $1,820,503 for the nine months ended
September 30, 2004; a net loss of $1,949,621 on zero sales for the year ended
December 31, 2003; a net loss of $2,265,677 on net sales of $22,759 for the year
ended December 31, 2002; and a cumulative loss from inception through September
30, 2004, of $15,780,865.

InforMedix has funded its operating activities primarily through sales of equity
securities to its founders, individual accredited investors, corporate
investors, private investment lenders and equity issued for services in the
amount of approximately $16,238,000 as of September 30, 2004. In addition, from
inception to December 31, 2002, InforMedix borrowed $725,000 from its Chief

<PAGE>

Executive Officer, directors and private investors all of which has been
converted into equity, an additional $65,000 in 2003, and completed a $400,000
debt bridge financing in September 2003. Between December 2003 and February
2004, we raised an additional $5.0 million under the Equity Offering which was
then terminated. InforMedix anticipates negative cash flow from operations to
continue for some time. We do not anticipate that this form of shareholder and
executive officer funding will continue. Accordingly, we can give no assurance
that we will be able to operate profitably or be able to produce positive cash
flow from operations in the future. Our efforts to operate profitably and obtain
positive cash flow from operations will depend on, among other things:

      o     Developing the InforMedix brand, marketing and other promotional
            activities of he Med-e Monitor System;
      o     Expanding general and administrative functions to support growth
            that may occur; and
      o     Establishing and developing relationships in the healthcare
            industry, particularly with pharmaceutical and biotechnology
            manufacturers, contract research organization (CROs) and academic
            research centers.

Qualified financial statements based on operating losses and a capital deficit
question InforMedix's ability to continue in business.

InforMedix's accountants issued a qualified report on our financial statements
as at and for the year ended December 31, 2003. The report states that
InforMedix is currently in the development stage and there is no guarantee
whether the Company will be able to generate enough revenue and/or raise capital
to support current operations and expand sales. This raises substantial doubt
about InforMedix's ability to continue as a going concern. See "Independent
Auditor' Report" and "Note 13 of Notes to InforMedix Consolidated Financial
Statements" included in the Annual Report on Form 10-K for December 31, 2003,
attached as Exhibit C to this Memorandum.

If we fail to establish the Med-e Monitor System brand or to attract repeat
customers, InforMedix may not be able to increase its revenues sufficiently to
fund its operations.

We must develop, establish and strengthen the InforMedix brand for the Med-e
Monitor System, particularly because of the early stage of our development and
the highly competitive nature of our business. If we fail to establish the Med-e
Monitor System brand, we will be at a competitive disadvantage and may lose the
opportunity to obtain, and thereafter maintain, a sufficient number of
customers. The development of the Med-e Monitor System brand will depend largely
on the success of InforMedix's marketing efforts and its ability to provide
consistent, high quality customer experiences. We cannot be certain that the
Med-e Monitor System brand promotion activities will be successful, or will
result in increased revenues. If increased revenues are achieved, there can be
no assurance that these revenues will be sufficient to offset the expenditures
incurred in establishing the Med-e Monitor System brand.

InforMedix is obligated to comply with government regulation and its failure to
do so could result in significant liability and curtailment or suspension of
operations.

The technology used in the monitoring of clinical drug trial protocols is
regulated by the Food and Drug Administration (FDA). No FDA approval is required
for the Med-eMonitor System and the FDA currently does not require the
documentation of regulatory compliance. However, if in the future the FDA
requires InforMedix to document regulatory compliance and it fails to do so,
because of a lack of funds, or otherwise, the Company may be required to curtail
or suspend its operations.

We will lack business diversification.

As a result of our limited resources, the prospects for our initial success will
be entirely dependent upon the future performance of a single product and a
single business. Unlike certain entities that have the resources to consummate
several business combinations or entities operating in multiple industries or
multiple segments of a single industry, we will not have the resources to
diversify our operations or benefit from the possible spreading of risks or
offsetting of losses.

We were recently organized and went public and have a limited operating history
upon which you can base an investment decision.

<PAGE>

We were organized on January 27, 1997, completed our reverse merger and became a
public company in May 2003, and have a limited operating history upon which you
can make an investment decision, or upon which we can accurately forecast future
sales. You should, therefore, consider us subject to all of the business risks
associated with a new business. The likelihood of our success must be considered
in light of the expenses, difficulties and delays frequently encountered in
connection with the formation and initial operations of a new and unproven
business.

Offering Risks

Discretion in use of funds.

InforMedix anticipates applying the net proceeds of this Offering solely for
working capital purposes and not for debt repayment. We have no material
restrictions on our use of the proceeds from the sale of the Securities. As
such, management of InforMedix shall have broad discretion, subject to their
fiduciary duties, in the application of the proceeds from the sale of the
Securities. See "Use of Proceeds."

No minimum commitment.

The Offering is being made on a "best efforts" rather than a "firm commitment"
basis, and no assurance can be given that any number of Warrants will be
exchanged. Accordingly, the Company may receive only nominal proceeds, and need
additional financing immediately thereafter.

Securities Risks

InforMedix's CEO, President and directors may have the ability to control almost
all matters of the Company.

The officers and directors of InforMedix and their affiliates, beneficially own
approximately 14% of the issued and outstanding shares of common stock of
InforMedix prior to this Offering. Therefore, management will have significant
influence over the election of InforMedix's directors and to control the outcome
of other issues submitted to stockholders of InforMedix. This includes their
ability to amend the Certificate of Incorporation, approve a merger or
consolidation of InforMedix with another company or approve the sale of all or
substantially all of the assets of InforMedix without the agreement of the
warrantholders who exercise warrants offered hereby.

Restrictions on transferability will prevent investors in this Offering from
selling the securities offered hereby.

This Offering of the Securities is being made pursuant to Sections 4(2) and 4(6)
of the Securities Act and Rule 506 of Regulation D promulgated under the
Securities Act, solely to Accredited Investors who are existing Warrantholders
of the Company. The shares of Common Stock underlying the Warrants have been
registered under the Securities Act; however, a post-effective amendment
describing this Offering must be declared effective before the Securities can be
sold, transferred, pledged, assigned, hypothecated or otherwise disposed of
under the Securities Act and such state laws, unless in the opinion of counsel
satisfactory to InforMedix, any such sale, transfer, assignment, pledge or
hypothecation will not violate the registration requirements under the
Securities Act or state securities laws. As a result, an investor must bear the
economic risk of an investment in InforMedix for an indefinite period of time.

If we do not keep our existing registration statement current, you will not be
able to receive registered stock under this Offering.

We must file a post-effective amendment to our existing registration statement
with the SEC or file a second registration statement covering the shares of
Common stock issuable in exchange for the Warrants surrendered under this
Offering in order for you to have registered Common Stock. We may not be able to

<PAGE>

maintain a registration statement in effect throughout the period during which
you wish to sell Securities. Maintaining an effective registration statement
requires substantial continuing expenses for legal and accounting fees and we
cannot guarantee our ability to keep the registration statement effective.

Your resale of Securities you acquire in this Offering may be limited.

The sale of Securities may only be made in the states where the initial
warrantholders reside. We have been unable to obtain registration for the
issuance of the underlying securities and/or the resale of the underlying
securities in the state where you live during the period when the Warrants are
exercisable. Therefore, you cannot sell securities issuable to you in this
Offering unless either (a) the securities issuable upon exchange of the Warrants
are registered in your state or (b) an exemption from registration is available.
We may not be able to qualify the resale of the Securities, in your state.

Preferred Stock as an anti-takeover device.

InforMedix is authorized to issue 4,500,000 shares of preferred stock, $.001 par
value. The preferred stock may be issued in series from time to time with such
designation, voting and other rights, preferences and limitations as the Board
of Directors of InforMedix may determine by resolution. Unless the nature of a
particular transaction and applicable statutes require such approval, the Board
of Directors has the authority to issue these shares without shareholder
approval subject to approval of the holders of the Preferred Stock. The issuance
of preferred stock may have the effect of delaying or preventing a change in
control of InforMedix without any further action by shareholders.

Interests of Financial Advisor in InforMedix; Possible Restriction on "Marketing
Making" Activities in InforMedix's Securities; Illiquidity.

Including shares underlying presently exercisable warrants, MA, our Financial
Advisor and Placement Agent for the 2005-2004 Private Placement and its
principals beneficially own, in the aggregate, 10,279,862 shares of Common
Stock, or approximately 30.9% of the outstanding shares. Notwithstanding the
foregoing, MA has entered into a Voting Agreement with us dated August 21, 2003,
pursuant to which the Placement Agent gave Management of InforMedix a voting
proxy over all of its shares on all matters for generally one year from the last
closing of this Offering in March 2004. Such interests should be considered by
potential investors when evaluating an investment in the Units because a
potential conflict of interest may exist.

Limited Transferability of Securities; Lack of Trading Market.

Purchasers of the Securities offered hereby must be aware of the long-term
nature of their investment and be able to bear the economic risks of their
investment for an indefinite period of time. The right of any Investor to sell,
transfer, pledge or otherwise dispose of the Securities included therein will be
limited by the Securities Act and state securities laws and the regulations
promulgated thereunder. Accordingly, under the Securities Act, the shares of
Common Stock may not be resold unless a registration statement is filed and
becomes effective or an exemption from registration is available. Although the
shares of Common Stock underlying the Warrants have been registered with the
SEC, a PE Amendment needs to be filed to describe this Offering within 10 days
following the Final Closing and/or a new Registration Statement covering the
additional shares of Common Stock received upon exchange of the Warrants, there
can be no assurance that any registration statement covering such securities
will become effective. Further, even if a registration does become effective,
there can be no assurance that a liquid market for the Common Stock will be
sustained. Rule 144 promulgated under the Securities Act requires, among other
conditions, a one-year holding period prior to the resale (in limited amounts)
of securities acquired in a non-public offering without having to satisfy the
registration requirements of the Securities Act. There can be no assurance that
we will fulfill in the future any reporting requirements under the Exchange Act,
or disseminate to the public any current financial or other information
concerning InforMedix, as required by Rule 144 as one of the conditions of its
availability.

Difficulty of Trading and Obtaining Quotations for Common Stock.

InforMedix's Common Stock is currently quoted on the NASD's Over-the-Counter
Bulletin Board ("OTCBB") under the symbol "IFMX." Our Common Stock is not

<PAGE>

actively traded, and the bid and asked prices for our Common Stock have
fluctuated significantly. As a result, an investor may find it difficult to
dispose of, or to obtain accurate quotations of the price of, our securities.
This severely limits the liquidity of the Common Stock, and would likely have a
material adverse effect on the market price of the Common Stock and on our
ability to raise additional capital.

Penny Stock regulation is expected to adversely affect the market for the
Company's securities.

The trading of the our Common Stock is currently subject to Rule 15g-9
promulgated under the Securities Exchange Act of 1934 (the "Exchange Act"), as
amended for non-Nasdaq and non-exchange listed securities. Under such rule,
brokers-dealers who recommend such securities to persons other than established
customers and accredited investors must make a special written suitability
determination for the purchaser and receive the purchaser's written agreement to
a transaction prior to sale. Securities are exempt from this rule if the market
price is at least $5.00 per share.

The Commission has adopted regulations that generally define a "penny stock" to
be an equity security that has a market price of less than $5.00 per share or an
exercise price of less than $5.00 per share subject to certain exceptions. Such
exceptions include equity securities listed on Nasdaq and equity securities
issued by an Company that has (i) net tangible assets of at least $2,000,000, if
such Company has been in continuous operation for more than three years, or (ii)
net tangible assets of at least $5,000,000, if such Company has been in
continuous operation for less than three years, or (iii) average revenue of at
least $6,000,000 for the preceding three years. Unless an exception is
available, the regulations require the delivery, prior to any transaction
involving a penny stock, of a risk disclosure schedule explaining the penny
stock market and the risks associated therewith.

Our Common Stock is currently a penny stock as defined in the Exchange Act and
as such, the market liquidity for the Common Stock is limited to the ability of
broker-dealers to sell Common Stock in compliance with the above-mentioned
disclosure requirements.

Risk Factors Affecting InforMedix's Business Operations.

      InforMedix could be subject to fines, facility shutdowns and possible
exclusion from participation in providing information technology services to
clinical drug trade if it fails to comply with the laws and regulations
applicable to its business or if those laws and regulations change.

InforMedix is subject to regulations such as compliance and record-keeping
requirements under the Health Insurance Portability and Accountability Act
(HIPAA) and the Food, Drug and Cosmetic Act. In addition, the provision of
services, pharmaceuticals and equipment is subject to strict licensing and
safety requirements. If InforMedix is deemed to have violated these laws and
regulations, InforMedix could be subject to fines and/or facility shutdowns.
Government officials and the public will continue to debate healthcare reform.
Changes in healthcare law, new interpretations of existing laws, or changes in
payment methodology for pharmaceuticals may have a dramatic effect on
InforMedix's business and results of operations.

Continued pressure could reduce InforMedix's margins and limit InforMedix's
ability to maintain or increase its market share.

Certain competitors of InforMedix may have or may obtain significantly greater
financial and marketing resources than InforMedix. As a result, InforMedix could
encounter increased competition in the future that may increase pricing pressure
and limit its ability to maintain or increase its market share.

If we lost the services of Dr. Bruce Kehr, InforMedix's CEO, or Randy Dulin,
InforMedix's Senior Vice President of Business Development and Operations, we
might not be able to execute InforMedix's current business in accordance with
our current plans.

InforMedix's future success depends significantly on the skills, experience and
efforts of its chief executive officer, Dr. Bruce Kehr, and its Senior Vice
President of Business Development and Operations, Randy Dulin, and other key

<PAGE>

personnel. These individuals would be difficult to replace. Dr. Kehr or Mr.
Dulin have developed, and are engaged in carrying out, InforMedix's strategic
business plan. The loss of the services of Dr. Kehr or Mr. Dulin could seriously
harm InforMedix's ability to implement its strategy. A failure to implement
InforMedix's business strategy could result in the cessation of InforMedix's
operations which would have a material adverse effect on our company and on your
investment.

If InforMedix is unable to adequately protect or enforce its rights to its
intellectual property, InforMedix may lose valuable rights, experience reduced
market share, if any, or incur costly litigation to protect such rights.

InforMedix generally requires its employees, consultants, advisors and
collaborators to execute appropriate confidentiality agreements with it. These
agreements typically provide that all materials and confidential information
developed or made known to the individual during the course of the individual's
relationship with InforMedix is to be kept confidential and not disclosed to
third parties except in specific circumstances. These agreements may be
breached, and in some instances, InforMedix may not have an appropriate remedy
available for breach of the agreements. Furthermore, InforMedix's competitors
may independently develop substantial equivalent proprietary information and
techniques, reverse engineer information and techniques, or otherwise gain
access to InforMedix's proprietary technology. In addition, the laws of some
foreign countries may not protect proprietary rights to the same extent as U.S.
law. InforMedix may be unable to meaningfully protect its rights in trade
secrets, technical know-how and other non-patented technology.

InforMedix may have to resort to litigation to protect its rights for certain
intellectual property, or to determine their scope, validity or enforceability.
Enforcing or defending InforMedix's rights is expensive and may distract
management from its development of the business if not properly managed. Such
efforts may not prove successful. There is always a risk that patents, if
issued, may be subsequently invalidated, either in whole or in part, and this
could diminish or extinguish protection for any technology InforMedix may
license. Any failure to enforce or protect InforMedix's rights could cause it to
lose the ability to exclude others from using its technology to develop or sell
competing products.

InforMedix may be sued by third parties who claim that InforMedix's product
infringes on their intellectual property rights. Defending an infringement
lawsuit is costly and InforMedix may not have adequate resources to defend. Any
settlement or judgment against us could harm our future prospects.

InforMedix may be exposed to future litigation by third parties based on claims
that its technology, product or activity infringes on the intellectual property
rights of others or that InforMedix has misappropriated the trade secrets of
others. This risk is compounded by the fact that the validity and breadth of
claims covered in technology patents in general and the breadth and scope of
trade secret protection involves complex legal and factual questions for which
important legal principles are unresolved. Any litigation or claims against
InforMedix, whether or not valid, could result in substantial costs, could place
a significant strain on InforMedix's financial and managerial resources, and
could harm InforMedix's reputation. In addition, intellectual property
litigation or claims could force InforMedix to do one or more of the following:

      o     Cease selling, incorporating or using any of InforMedix's technology
            and/or product that incorporates the challenged ntellectual
            property, which could adversely affect InforMedix's revenue;

      o     Obtain a license from the holder of the infringed intellectual
            property right, which may be costly or may not be available on
            reasonable terms, if at all; or

      o     Redesign InforMedix's product, which would be costly and time
            consuming.

We may not be able to manufacture our planned product in sufficient quantities
at an acceptable cost, or at all, which could harm our future prospects.

InforMedix is in the initial phase of product commercialization. InforMedix does
not presently own any manufacturing facilities. Accordingly, if InforMedix's
planned product becomes available for widespread sale, we may not be able to
arrange for the manufacture of our planned product in sufficient quantities at
an acceptable cost, or at all, which could materially adversely affect
InforMedix's future prospects.

<PAGE>

The market for InforMedix's planned product is rapidly changing and competitive.
New products may be developed by others which could impair our ability to
develop, grow or maintain our business and be competitive.

InforMedix's industry is subject to substantial technological change.
Developments by others may render InforMedix's technology and planned product
noncompetitive or obsolete, or it may be unable to keep pace with technological
developments or other market factors. Competition from other companies,
universities, government research organizations and others diversifying into the
field is intense and is expected to increase. Many of these entities have
significantly greater research and development capabilities and budgets than
InforMedix does, as well as substantially more marketing, manufacturing,
financial and managerial resources. These entities could represent significant
competition for InforMedix. InforMedix is a development-stage enterprise and as
such its resources are limited and it may experience technical challenges
inherent in developing its technology. Competitors have developed or are in the
process of developing technologies that are, or in the future may be, the basis
for competition.

InforMedix's planned product could be exposed to significant product liability
claims which could be time consuming and costly to defend, divert management
attention and adversely affect InforMedix's ability to obtain and maintain
insurance coverage. If InforMedix incurred a material liability for which it is
not adequately insured, it might be rendered insolvent.

The testing, manufacture, marketing and sale of InforMedix's planned product
will involve an inherent risk that product liability claims will be asserted
against it. We currently have a general liability policy with an annual
aggregate limit of $1 million with a $1 million limit per occurrence and product
liability insurance with an aggregate limit of $1 million. This insurance may
prove inadequate to cover claims and/or litigation costs. Product liability
claims or other claims related to InforMedix's planned product, regardless of
their outcome, could require us to spend significant time and money in
litigation or to pay significant settlement amounts or judgments. Any successful
product liability or other claim may prevent InforMedix from obtaining adequate
liability insurance in the future on commercially desirable or reasonable terms.
In addition, product liability coverage may cease to be available in sufficient
amounts or at an acceptable cost. Any inability to obtain sufficient insurance
coverage at an acceptable cost or otherwise to protect against potential product
liability claims could prevent or inhibit the sale of InforMedix's planned
product.

InforMedix faces the risk of liability resulting from claims made directly by
patients. InforMedix currently has property, general liability and product
liability insurance in amounts that we believe to be adequate, but InforMedix
can give no assurance that such insurance will remain available at a reasonable
price or that any insurance policy would offer coverage sufficient to meet any
liability arising as a result of a claim. We can give no assurance that
InforMedix will be able to obtain or maintain adequate insurance on reasonable
terms or that, if obtained, such insurance will be sufficient to protect against
such potential liability or at a reasonable cost. The obligation to pay any
substantial liability claim could render InforMedix insolvent and could force it
to curtail suspend operations, which would have a material adverse effect on our
company and your investment in our company.

      9.19  It is agreed that a waiver by either party of a breach of any
            provision of this Agreement shall not operate, or be construed, as a
            waiver of any subsequent breach by that same party.

      9.20  The parties agree to execute and deliver all such further documents,
            agreements and instruments and take such other and further action as

                                    ARTICLE X
                 DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

      Statements in this Agreement are certain statements which are not
historical or current fact and constitute "forward-looking statements" within
the meaning of such term in Section 27A of the Securities Act of 1933 and
Section 21E of the Securities Exchange Act of 1934. Such forward-looking
statements involve known and unknown risks, uncertainties and other factors that
could cause the actual financial or operating results of the Company to be
materially different from the historical results or from any future results
expressed or implied by such forward-looking statement. Such forward-looking
statements are based on our best estimates of future results, performance or
achievements, based on current conditions and the most recent results of the
Company. In addition to statements which explicitly describe such risks and
uncertainties, readers are urged to consider statements labeled with the terms
"may," "will," "potential," "opportunity," "believes," "belief," "expects,"
"intends," "estimates," " anticipates" or "plans" to be uncertain and
forward-looking. The forward-looking statements contained herein are also
subject generally to other risks and uncertainties that are described from time
to time in the Company's reports and registration statements filed with the
Securities and Exchange Commission. Consequently, all of the forward-looking
statements made in this Agreement are qualified by these cautionary statements
and there can be no assurance that the actual results anticipated by the Company
will be realized or, even if substantially realized, that they will have the
expected consequences to or effects on the Company or its business or
operations.
