         THIS REGISTRATION RIGHTS AGREEMENT (this "Agreement") is made as of May
7, 2004, by and between Critical Home Care, Inc., a Nevada corporation (the
"Company"), and John E. Elliott, II and Lawrence R. Kuhnert (individually a
"Shareholder" and collectively the "Shareholders").

         WHEREAS, the Company, the Shareholders and certain others entered into
an Agreement and Plan of Merger dated May 7, 2004, to be effective May 10, 2004,
(the "Merger Agreement"), providing for certain transactions which when
consummated, will result in the issuance by the Company to the Shareholders, of
certain of the Company's issued and outstanding, voting, $.001 par value, common
stock as follows:

         John E. Elliott, II        12,780,000 Shares

         Lawrence R. Kuhnert        8,520,000 Shares

         John E. Elliott, II        600,000 Warrant Shares

         Lawrence R. Kuhnert        400,000 Warrant Shares

(collectively, the "Shares"). The Shares will be evidenced by certificates
and/or other instruments to be prepared after the date of this Agreement. The
Shareholders may further identify the Shares covered by this Agreement by
delivering a writing to the Company, identifying the Shares by certificate
number.

         WHEREAS, pursuant to Article 2.4(e) of the Merger Agreement, the
Company is obligated to cause the Shares to be registered for resale with the
United States Securities and Exchange Commission (the "SEC"), in accordance with
the Securities Act of 1933 (the "Act") and any and all applicable states, in
accordance with the securities laws of such states (the "Blue Sky Laws").

         WHEREAS, the parties desire to enter into this Agreement to provide for
the registration of the Shares.

         NOW, THEREFORE, in consideration of the promises and the mutual
agreements and covenants herein contained, the parties hereto agree as follows:

         1.       Registration. The Company shall register with the SEC the
Shares for public sale by the Shareholders, in their discretion, either in the
public market or in negotiated transactions from time to time under the Act and
any applicable Blue Sky Laws (the "Registration"). The Registration (and
registration statement) shall be made effective on or before November 7, 2004
and shall thereafter, be made and kept continuously effective for so long as the
Shareholders shall hold any of the Shares.
<PAGE>

         2. Registration Procedures. The Shareholders shall furnish to the
Company such information regarding them, the Shares held by them, the intended
method of their disposition of the Shares, and such information as the Company
shall reasonably request and as shall be legally required, in connection with
the Registration of the Shares.

         The Company shall:

                  (a) prepare and file with the SEC, a registration statement on
         the appropriate form prescribed by the SEC and cause such registration
         statement to become effective on or before November 7, 2004. The
         Registration (including any amendments or supplements thereto and
         prospectuses contained therein) shall not contain any 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, in light
         of the circumstances in which they were made, not misleading;

                  (b) prepare and file with the SEC, such amendments,
         post-effective amendments and supplements to such registration
         statement and any documents required to be incorporated by reference
         therein as may be necessary to keep the registration statement
         effective until the distribution of Shares shall have been completed;
         cause the prospectus to be supplemented by any required prospectus
         supplement, and as so supplemented to be filed pursuant to Rule 424
         under the Act (or any successor rule); and comply with the provisions
         of the Act applicable to it with respect to the disposition of the
         Shares covered by such registration statement during the applicable
         period in accordance with the intended methods of disposition of the
         Shares being sold by the Shareholders, set forth in such registration
         statement or supplement to the prospectus. In the case of amendments
         and supplements to the Registration that are required to be filed
         pursuant to this Agreement (including pursuant to this Section 3(b)) by
         reason of the Company filing a report on Form 10-KSB, Form 10-QSB or
         Form 8-K or any analogous report under the Securities Exchange Act of
         1934, as amended (the "Exchange Act"), the Company shall file such
         amendments or supplements with the SEC on the same day or as soon as
         practicably thereafter on which the Exchange Act report is filed that
         created the requirement for the Company to amend or supplement the
         Registration;

                  (c) furnish to each Shareholder at least one (1) conformed
         copy of the registration statement and any post-effective amendment
         thereto, upon request, and such number of copies of the prospectus
         (including each preliminary prospectus) and any amendments or
         supplements thereto, and any exhibits or documents incorporated by
         reference therein as the Shareholders or underwriter or underwriters,
         if any, may reasonably request in order to facilitate the disposition
         of the Shares being sold by the Shareholders;

                  (d) on or prior to the date on which the registration
         statement is declared effective, to register or qualify, and to
         cooperate with the Shareholders, the underwriter or underwriters, if
         any, and their counsel in connection with the registration or
         qualification of the Shares covered by the registration statement for

                                       2
<PAGE>

         offer and sale under the Act or Blue Sky Laws of each state and other
         jurisdiction of the United States as the Shareholders or underwriter or
         underwriters, if any, may request (considering the nature or size of
         the offering and the expense and time involved in such qualification or
         registration), and to do any and all other acts or things which may be
         necessary or advisable to enable the disposition in all such
         jurisdictions of the Shares covered by the applicable registration
         statement;

                  (e) cause the Shares covered by the registration statement to
         be registered with or approved by such other governmental agencies or
         authorities within the United States, including, without limitation,
         any filing required to be made by the underwriter or underwriters, if
         any, with a stock market, exchange or quotation service (such as New
         York Stock Exchange, American Stock Exchange, NASDAQ, OTCBB or Pink
         Sheets Service), as may be necessary to enable the seller or sellers
         thereof or the underwriter or underwriters, if any, to consummate the
         disposition of the Shares;

                  (f) prior to the effective date of a registration statement
         covering the Shares (i) cooperate with the holders of the Shares to
         provide certificates for the Shares in a form eligible for deposit with
         The Depository Trust Company and (ii) provide a CUSIP number for the
         Shares to be offered;

                  (g) provide a transfer agent and registrar for all such Shares
         not later than the effective date of the first registration statement
         relating to the Shares and co-operate to make certificates promptly
         available;

                  (h) list or have included for trading the Shares on any stock
         exchange or interdealer quotation system upon which other securities of
         the Company of the same class are listed or included for trading; and

                  (i) enter into customary underwriting and other agreements and
         obtain cold comfort letters and/or legal opinion letters in customary
         form as may be requested by any underwriter or the Shareholders.

                  (j) notify each seller of such Shares, at any time when a
         prospectus relating thereto is required to be delivered under the Act,
         of the happening of any event as a result of which the prospectus
         included in such registration statement contains an untrue statement of
         a material fact or omits any fact necessary to make the statements
         therein not misleading, and, at the request of any such seller, the
         Company shall promptly prepare a supplement or amendment to such
         prospectus and/or registration statement so that, as thereafter
         delivered to the purchasers of such Shares, such prospectus shall not
         contain an untrue statement of a material fact or omit to state any
         fact necessary to make the statements therein not misleading;

                  (k) make available for inspection by any seller of Shares, any
         underwriter participating in any disposition pursuant to such
         registration statement and any attorney, accountant or other agent
         retained by any such seller

                                       3
<PAGE>

         or underwriter, all financial and other records, pertinent corporate
         documents and properties of the Company, and cause the Company's
         officers, directors, employees and independent accountants to supply
         all information reasonably requested by any such seller, underwriter,
         attorney, accountant or agent in connection with such registration
         statement;

                  (l) otherwise use its best efforts to comply with all
         applicable rules and regulations of the SEC, and make available to its
         security holders, as soon as reasonably practicable, an earnings
         statement covering the period of at least twelve months beginning with
         the first day of the Company's first full calendar quarter after the
         effective date of the registration statement, which earnings statement
         shall satisfy the provisions of Section 11(a) of the Act and Rule 158
         thereunder;

                  (m) in the event of the issuance of any stop order suspending
         the effectiveness of a registration statement, or of any order
         suspending or preventing the use of any related prospectus or
         suspending the qualification of any securities included in such
         registration statement for sale in any jurisdiction, the Company shall
         notify the Shareholders thereof and use its best efforts promptly to
         obtain the withdrawal of such order;

                  (n) The Company shall hold in confidence and not make any
         disclosure of information concerning a Shareholder provided to the
         Company unless (i) disclosure of such information is necessary to
         comply with Federal or state securities laws, (ii) the disclosure of
         such information is necessary to avoid or correct a misstatement or
         omission in the Registration, (iii) the release of such information is
         ordered pursuant to a subpoena or other final, non-appealable order
         from a court or governmental body of competent jurisdiction, or (iv)
         such information has been made generally available to the public other
         than by disclosure in violation of this Agreement or any other
         agreement. The Company agrees that it shall, upon learning that
         disclosure of such information concerning a Shareholder is sought in or
         by a court or governmental body of competent jurisdiction or through
         other means, give prompt written notice to such Shareholder and allow
         such Shareholder, at the Shareholder's expense, to undertake
         appropriate action to prevent disclosure of, or to obtain a protective
         order for, such information; and

                  (o) use its best efforts to cause its management to
         participate fully in the sale process, including, without limitation,
         the preparation of the registration statement and the preparation and
         presentation of any "road shows," whether domestic or international.

         3.       Registration Expenses. The Company shall bear and pay all
expenses in connection with the Registration, including, without limitation, the
expenses of preparing any registration statement; SEC and state "blue sky"
filing, registration and qualification fees and expenses; fees and expenses
associated with filings required to be made with the NASD; fees and expenses of
counsel for the Company, independent public accountants

<PAGE>

(including, without limitation, the cost of providing any legal opinions or
"cold comfort" letters); underwriters and other persons retained by the Company,
fees and expenses and disbursements of counsel for the Shareholders.

         4.       Indemnification.

                  (a) To the fullest extent permitted by law, the Company will,
         and hereby does, indemnify, hold harmless and defend each Shareholder
         who holds such Shares, against any losses, claims, damages,
         liabilities, judgments, fines, penalties, charges, costs, attorneys'
         fees, amounts paid in settlement or expenses, joint or several
         (collectively, "Losses"), incurred in investigating, preparing or
         defending any action, claim, suit, inquiry, proceeding, investigation
         or appeal taken from the foregoing by or before any court or
         governmental, administrative or other regulatory agency or body or the
         SEC, whether pending or threatened, whether or not an indemnified party
         is or may be a party thereto to which any of them may become subject
         insofar as such Losses (or actions or proceedings, whether commenced or
         threatened, in respect thereof) arise out of or are based upon: (i) any
         untrue statement or alleged untrue statement of a material fact in the
         Registration or any post-effective amendment thereto or in any filing
         made in connection with the qualification of the offering under the
         securities or other "blue sky" laws of any jurisdiction in which Shares
         are offered, or the omission or alleged omission to state a material
         fact required to be stated therein or necessary to make the statements
         therein not misleading, (ii) any untrue statement or alleged untrue
         statement of a material fact contained in any preliminary prospectus if
         used prior to the effective date of such Registration, or contained in
         the final prospectus (as amended or supplemented, if the Company files
         any amendment thereof or supplement thereto with the SEC) or the
         omission or alleged omission to state therein any material fact
         necessary to make the statements made therein, in light of the
         circumstances under which the statements therein were made, not
         misleading, (iii) any violation or alleged violation by the Company of
         the Act, the Exchange Act, any other law, including, without
         limitation, any state securities law, or any rule or regulation
         thereunder relating to the offer or sale of the Shares pursuant to the
         Registration or (iv) any material violation of this Agreement. The
         indemnification provided for under this Agreement shall remain in full
         force and effect regardless of any investigation made by or on behalf
         of the indemnified party or any officer, director or controlling person
         of such indemnified party and shall survive the transfer of Shares.
         This indemnification shall also be given by the Company with respect to
         any required registration or other qualification of Shares under any
         federal or state law or regulation of any governmental authority other
         than the Act. The indemnification required by this Section 4 shall be
         made by periodic payments of the amount thereof during the course of
         the investigation or defense, as and when bills are received or Losses
         are incurred. The provisions of this Section 4 shall be in addition to
         any other rights to indemnification or contribution which a Shareholder
         may have pursuant to law, equity, contract or otherwise.

                                       5
<PAGE>

                  (b) If the indemnity and reimbursement obligation provided for
         in any paragraph of this Section 4 is unavailable or insufficient to
         hold harmless a Shareholder in respect of any Losses (or actions or
         proceedings in respect thereof) referred to therein, then the Company
         shall contribute to the amount paid or payable by the Shareholder as a
         result of such Losses (or actions or proceedings in respect thereof) in
         such proportion as is appropriate to reflect the relative fault of the
         Company on the one hand and the Shareholder on the other hand in
         connection with statements or omissions which resulted in such Losses,
         as well as any other relevant equitable considerations. The relative
         fault shall be determined by reference to, among other things, whether
         the untrue or alleged untrue statement of a material fact or the
         omission or alleged omission to state a material fact relates to
         information supplied by the Company or the Shareholder and the parties'
         relative intent, knowledge, access to information and opportunity to
         correct or prevent such untrue statement or omission. The parties
         hereto agree that it would not be just and equitable if contributions
         pursuant to this paragraph were to be determined by pro rata allocation
         or by any other method of allocation which does not take account of the
         equitable considerations referred to in the first sentence of this
         paragraph. The amount paid by a Shareholder as a result of the Losses
         referred to in the first sentence of this paragraph shall be deemed to
         include any legal and other expenses reasonably incurred by such
         Shareholder in connection with investigation or defending any Loss
         which is the subject of this paragraph. No Shareholder guilty of
         fraudulent misrepresentation (within the meaning of Section 11(f) of
         the Act) shall be entitled to contribution from the Company if the
         Company was not guilty of such fraudulent misrepresentation.

         5.       Miscellaneous.

                  (a) Mutual Rights of the Shareholders. Each, every and all of
         the rights provided in this Agreement to the Shareholders and further,
         each, every and all of the obligations of the Company, shall be
         extended to each Shareholder individually or the Shareholders
         collectively, as the Shareholders may elect.

                  (b) No Inconsistent Agreements. The Company shall not
         hereafter enter into any agreement with respect to its securities that
         is inconsistent with or violates the rights granted to the
         Shareholders.

                  (c) Adjustments Affecting Shares. The Company shall not take
         any action, or permit any change to occur, with respect to its
         securities which would materially and adversely affect the ability of
         the Shareholders to include the Shares in a registration undertaken
         pursuant to this Agreement or which would materially and adversely
         affect the marketability of the Shares in any such registration
         (including, without limitation, effecting a stock split or a
         combination of shares).

                  (d) Remedies. Any Shareholder having rights under any
         provision of this Agreement shall be entitled to enforce such rights
         specifically to recover damages caused by reason of any breach of any
         provision of this Agreement and

                                       6
<PAGE>

         to exercise all other rights granted by law. Remedies available
         specifically hereunder are cumulative with each other and with all
         other remedies available at law and not specifically precluded hereby.
         The parties hereto agree and acknowledge that money damages may not be
         an adequate remedy for any breach of the provisions of this Agreement
         and that any party may in its sole discretion apply to any court of law
         or equity of competent jurisdiction (without posting any bond or other
         security) for specific performance and for other injunctive relief in
         order to enforce or prevent violation of the provisions of this
         Agreement.

                  (e) Amendments and Waivers. Except as otherwise provided
         herein, the provisions of this Agreement may be amended or waived only
         upon the prior written consent of the Company and the Shareholders.

                  (f) Successors and Assigns. All covenants and agreements in
         this Agreement by or on behalf of any of the parties hereto shall bind
         and inure to the benefit of the respective successors and assigns of
         the parties hereto whether so expressed or not, including, without
         limitation, any corporation or other entity into which the Company may
         be merged or converted. In addition, whether or not any express
         assignment has been made, the provisions of this Agreement which are
         for the benefit of the Shareholders are also for the benefit of, and
         enforceable by, any subsequent holder of the Shareholders.

                  (g) Severability. Whenever possible, each provision of this
         Agreement shall be interpreted in such manner as to be effective and
         valid under applicable law, but if any provision of this Agreement is
         held to be prohibited by or invalid under applicable law, such
         provision shall be ineffective only to the extent of such prohibition
         or invalidity, without invalidating the remainder of this Agreement.

                  (h) Counterparts. This Agreement may be executed
         simultaneously in two or more counterparts, any one of which need not
         contain the signatures of more than one party, but all such
         counterparts taken together shall constitute one and the same
         Agreement.

                  (i) Descriptive Headings. The descriptive headings of this
         Agreement are inserted for convenience only and do not constitute a
         part of this Agreement.

                  (j) Notices. All notices, demands or other communications to
         be given or delivered under or by reason of the provisions of this
         Agreement shall be in writing and shall be deemed to have been given
         when delivered personally to the recipient, sent to the recipient by
         reputable overnight courier service (charges prepaid), or sent via
         facsimile to the recipient accompanied by a certified registered

                  (k) GOVERNING LAW, JURY TRIAL AND JURISDICTION. ALL ISSUES AND
         QUESTIONS CONCERNING THE CONSTRUCTION, VALIDITY, INTERPRETATION AND
         ENFORCEMENT OF THIS AGREEMENT AND THE EXHIBITS AND SCHEDULES HERETO
         SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE
         STATE OF MICHIGAN, WITHOUT GIVING EFFECT TO ANY CHOICE OF LAW OR
         CONFLICT OF LAW RULES OR PROVISIONS (WHETHER OF THE STATE OF MICHIGAN
         OR ANY OTHER JURISDICTION) THAT WOULD CAUSE THE APPLICATION OF THE LAWS
         OF ANY JURISDICTION OTHER THAN THE STATE OF MICHIGAN. THE PARTIES
         HERETO SUBMIT TO THE NON-EXCLUSIVE JURISDICTION OF THE COURTS OF
         MICHIGAN.

                  (l) No Strict Construction. The parties hereto have
         participated jointly in the negotiation and drafting of this Agreement.
         In the event an ambiguity or question of intent or interpretation
         arises, this Agreement shall be construed as if drafted jointly by the
         parties hereto, and no presumption or burden of proof shall arise
         favoring or disfavoring any party by virtue of the authorship of any of
         the provisions of this Agreement.

                  (m) Transfer. Prior to transferring any Shares to any person,
         the Shareholder transferring such Shares will cause the prospective
         transferee to execute and deliver to the Company (for itself and as the
         agent of the other members), a counterpart to this Agreement pursuant
         to which the prospective transferee agrees to be bound by this
         Agreement to the same extent as the person transferring such Shares
         with respect to the Shares so transferred.

                  (n) Entire Agreement. Except as otherwise expressly set forth
         herein, this Agreement and the other agreements referred to herein
         embodies the complete agreement and understanding among the parties
         hereto with respect to the subject matter hereof and supersedes and
         preempts any prior understandings, agreements or representations by or
         among the parties, written or oral, which may have related to the
         subject matter hereof in any way.

notice to Payor to convert all of the outstanding principal, accrued , but unpaid interest and any other amounts owing under this

    9.     Registration Rights.    If at any time  the Payor proposes to register any of its securities under the
Securities Act in connection with the offering of such securities by the Payor (including, without limitation the
    registration of
securities in connection with the sale of 32,980,000 shares in Payor’s Regulation D Private Placement) or holders of such
securities (except pursuant to a registration statement filed on Form S-4 or on Form S-8 or such other forms as shall be prescribed
under the Securities Act for the same purposes or for any exchange offer) (a “Piggyback Registration”), the Payor shall
at such time promptly provide Payee written notice of its intention so to do.  Upon the written request of Payee given within
ten (10) days after providing of any such notice by the Payor, the Payor shall
    use reasonable efforts to 

5

	cause to be registered
under the Securities Act all of the Conversion Shares currently held or potentially held following a conversion by the Payee.   If the Payor in its sole discretion decides a Piggyback Registration shall be underwritten, the Payor
shall have sole discretion in the selection of any underwriter or underwriters to manage such Piggyback Registration.  If the managing underwriter or underwriters of a Piggyback Registration advise the Payor
in writing that in its or their opinion the number of registrable securities proposed to be sold in such Piggyback Registration
exceeds the number which can be sold, or adversely affects the price at which the registrable securities are to be sold in such
offering, the Payor will include in such registration only the securities, if any, which, in the opinion of such underwriter or
underwriters, can be sold in such offering or which will not adversely affect the price thereof.  In the event that the
contemplated distribution does not involve an underwritten offering, the determination that the inclusion of such registrable
securities shall adversely affect the price or the number of securities which may be sold in such offering shall be made by the
Payor in its reasonable judgment upon advice and consultation with a nationally recognized investment banker.  The securities
so included in such Piggyback Registration shall be apportioned pro rata among the securities that the Payor and any holder
proposes to sell, according to the total number of securities requested for inclusion by all such parties, or in such other
proportions as shall mutually be agreed to among the Payor and such holders.   It shall be a condition precedent to the
obligations of the Payor and any underwriter or underwriters to take any action pursuant to this Section 9, that the Payee
participating in any Piggyback Registration shall furnish to the Payor such information regarding it, the Conversion Shares held by
it, the intended method of disposition of such Conversion Shares, and such agreements regarding indemnification, disposition of
such securities and the other matters referred to in this Section 9, as the Payor shall reasonably request and as shall be required
in connection with the action to be taken by the Payor. 
	
    10.	
    Security Interest.   Payor and ArcadiaRx hereby grant to the Payee a continuing security
interest to the fullest extent permitted by law in all the tangible and intangible property of the Payor and ArcadiaRx now owned or
hereafter acquired and all products and proceeds therefrom including, without limitation, all accounts, goods, inventory,
equipment, fixtures, payment intangibles and general intangibles. 
	
    11.	
    Subordination.  This Note is subordinated in right of payment to Indebtedness (hereinafter defined), which includes any
principal of, premium, if any, or interest on indebtedness of Payor except Indebtedness which by its terms is not superior in right
of payment to the Note’s. For the purposes of this Note, the term “Indebtedness” shall mean all existing and
future indebtedness incurred in the ordinary course of business, including, but not limited to (1) bank debt of Payor, (2) any
lease, chattel mortgage, and conditional sales financing secured by Payor’s property and equipment; and, (3) any amendment,
renewal, extension or refunding of any such debt.  Each noteholder by accepting a Note agrees to this subordination and
authorizes Payor to give it effect.
	
    12.	
    Restriction on Transfer.  This Note has been acquired for investment, and neither this Note nor any of the Conversion
Shares issuable pursuant to a conversion pursuant to Section 8 herein have been registered under the securities laws of the United
States of America or any state thereof.  Accordingly, no interest in this Note may be offered for sale, sold or transferred in
the absence of registration and qualification of this Note or the Conversion Shares, as the case may be, under applicable federal
and state securities laws or an opinion of counsel of Payee reasonably satisfactory to Payor that such registration and
qualification are not required. 

6

	13.	
    Miscellaneous.
	 	
    13.1	The headings of the various paragraphs of this Note are for convenience of reference only and shall in no way modify any
of the terms or provisions of this Note.
	 	
    13.2	All notices required or permitted
    to be given hereunder shall be in writing and shall be deemed to have been duly given
when personally delivered or sent by registered or certified mail (return receipt requested, postage prepaid), facsimile
transmission or overnight courier to the address of the intended recipient as set forth in the preamble to this Note or at such
other address as the intended recipient shall have hereafter given to the other party hereto pursuant to the provisions of this
Note.
	 	
    13.3	This Note and the obligations of Payor and the rights of Payee shall be governed by and construed in accordance with the
substantive laws of the State of New York without giving effect to the choice of laws rules thereof.
