FOR VALUE RECEIVED, KAIRE HOLDINGS INCORPORATED, a Delaware corporation

Three Hundred Thousand Dollars ($300,000.00), with simple interest accruing at

                                   ARTICLE I

<PAGE>

                                  ARTICLE II

                               CONVERSION RIGHTS

     The Holder shall have the right to convert the principal amount and
interest due under this Note into Shares of the Borrower's Common Stock as set
forth below.

     2.1. Conversion into the Borrower's Common Stock.
          -------------------------------------------

          (a) The Holder shall have the right from and after the issuance of
this Note and then at any time until this Note is fully paid, to convert any
outstanding and unpaid principal portion of this Note, and/or at the Holder's
election, the interest accrued on the Note, (the date of giving of such notice
of conversion being a "Conversion Date") into fully paid and nonassessable
shares of common stock of Borrower as such stock exists on the date of issuance
of this Note, or any shares of capital stock of Borrower into which such stock
shall hereafter be changed or reclassified (the "Common Stock") at the
conversion price as defined in Section 2.1(b) hereof (the "Conversion Price"),
determined as provided herein.  Upon delivery to the Company of a Notice of
Conversion as described in Section 9 of the subscription agreement entered into
between the Company and Holder relating to this Note (the "Subscription
Agreement") of the Holder's written request for conversion, Borrower shall issue
and deliver to the Holder within three business days from the Conversion Date
that number of shares of Common Stock for the portion of the Note converted in
accordance with the foregoing.  At the election of the Holder, the Company will
deliver accrued but unpaid interest on the Note through the Conversion Date
directly to the Holder on or before the Delivery Date (as defined in the
Subscription Agreement).  The number of shares of Common Stock to be issued upon
each conversion of this Note shall be determined by dividing that portion of the
principal (and interest, at the election of the Holder) of the Note to be
converted, by the Conversion Price.

          (b) Subject to adjustment as provided in Section 2.1(c) hereof, the
Conversion Price per share shall be the lower of (i) eighty percent (80%) of the
average of the three lowest closing prices for the Common Stock on the NASD OTC
Bulletin Board, NASDAQ SmallCap Market, NASDAQ National Market System, American
Stock Exchange, or New York Stock Exchange (whichever of the foregoing is at the
time the principal trading exchange or market for the Common Stock, the
"Principal Market"), or if not then trading on a Principal Market, such other
principal market or exchange where the Common Stock is listed or traded for the
thirty (30) trading days prior to but not including the Closing Date (as defined
in the Subscription Agreement) in connection with which this Note is issued
("Maximum Base Price"); or (ii) eighty percent (80%) percent of the average of
the three lowest closing prices for the Common Stock on the Principal Market, or
on any securities exchange or other securities market on which the Common Stock
is then being listed or traded, for the sixty (60) trading days prior to but not
including the Conversion Date.

          (c) The Maximum Base Price described in Section 2.1(b)(i) above and
number and kind of shares or other securities to be issued upon conversion
determined pursuant to Section 2.1(a) and 2.1(b), shall be subject to adjustment
from time to time upon the happening of certain events while this conversion
right remains outstanding, as follows:

              A.  Merger, Sale of Assets, etc. If the Borrower at any time shall
consolidate with or merge into or sell or convey all or substantially all its
assets to any other corporation, this Note, as to the unpaid principal portion
thereof and accrued interest thereon, shall thereafter be deemed to evidence the
right to purchase such number and kind of shares or other securities and
property as would have been issuable or

                                       2
<PAGE>

distributable on account of such consolidation, merger, sale or conveyance, upon
or with respect to the securities subject to the conversion or purchase right
immediately prior to such consolidation, merger, sale or conveyance. The
foregoing provision shall similarly apply to successive transactions of a
similar nature by any such successor or purchaser. Without limiting the
generality of the foregoing, the anti-dilution provisions of this Section shall
apply to such securities of such successor or purchaser after any such
consolidation, merger, sale or conveyance.

              B.  Reclassification, etc.  If the Borrower at any time shall, by
reclassification or otherwise, change the Common Stock into the same or a
different number of securities of any class or classes, this Note, as to the
unpaid principal portion thereof and accrued interest thereon, shall thereafter
be deemed to evidence the right to purchase an adjusted number of such
securities and kind of securities as would have been issuable as the result of
such change with respect to the Common Stock immediately prior to such
reclassification or other change.

              C.  Stock Splits, Combinations and Dividends.  If the shares of
Common Stock are subdivided or combined into a greater or smaller number of
shares of Common Stock, or if a dividend is paid on the Common Stock in shares
of Common Stock, the Conversion Price shall be proportionately reduced in case
of subdivision of shares or stock dividend or proportionately increased in the
case of combination of shares, in each such case by the ratio which the total
number of shares of Common Stock outstanding immediately after such event bears
to the total number of shares of Common Stock outstanding immediately prior to
such event.

              D.  Share Issuance.  Subject to the provisions of this Section, if
the Borrower at any time shall issue any shares of Common Stock prior to the
conversion of the entire principal amount of the Note (otherwise than as: (i)
provided in Sections 2.1(c)A, 2.1(c)B or 2.1(c)C or this subparagraph D; (ii)
pursuant to options, warrants, or other obligations to issue shares, outstanding
on the date hereof as described in the Reports and Other Written Information, as
such terms are defined in the Subscription Agreement (which agreement is
incorporated herein by this reference); or (iii) Excepted Issuances, as defined
in Section 12 of the Subscription Agreement; ((i), (ii) and (iii) above, are
hereinafter referred to as the "Existing Option Obligations") for a
consideration less than the Conversion Price that would be in effect at the time
of such issue, then, and thereafter successively upon each such issue, the
Conversion Price shall be reduced as follows: (i) the number of shares of Common
Stock outstanding immediately prior to such issue shall be multiplied by the
Conversion Price in effect at the time of such issue and the product shall be
added to the aggregate consideration, if any, received by the Borrower upon such
issue of additional shares of Common Stock; and (ii) the sum so obtained shall
be divided by the number of shares of Common Stock outstanding immediately after
such issue. The resulting quotient shall be the adjusted conversion price.
Except for the Existing Option Obligations, for purposes of this adjustment, the
issuance of any security of the Borrower carrying the right to convert such
security into shares of Common Stock or of any warrant, right or option to
purchase Common Stock shall result in an adjustment to the Conversion Price upon
the issuance of shares of Common Stock upon exercise of such conversion or
purchase rights.

          (d) During the period the conversion right exists, Borrower will
reserve from its authorized and unissued Common Stock a sufficient number of
shares to provide for the issuance of Common

                                       3
<PAGE>

Stock upon the full conversion of this Note. Borrower represents that upon
issuance, such shares will be duly and validly issued, fully paid and non-
assessable. Borrower agrees that its issuance of this Note shall constitute full
authority to its officers, agents, and transfer agents who are charged with the
duty of executing and issuing stock certificates to execute and issue the
necessary certificates for shares of Common Stock upon the conversion of this
Note.

     2.2  Method of Conversion.  This Note may be converted by the Holder
          --------------------
in whole or in part as described in Section 2.1(a) hereof and the Subscription
Agreement.  Upon partial conversion of this Note, a new Note containing the same
date and provisions of this Note shall, at the request of the Holder, be issued
by the Borrower to the Holder for the principal balance of this Note and
interest which shall not have been converted or paid.


                                  ARTICLE III

                               EVENT OF DEFAULT

Default") shall, at the option of the Holder hereof, make all sums of principal
and interest then remaining unpaid hereon and all other amounts payable

writing its continuing obligation to afford to such holder any rights to which

the provisions of this Warrant. If the holder shall fail to make any such

to afford to such holder any such rights.

     1.6. Trustee for Warrant Holders. In the event that a bank or trust

name for the account of the Company or such successor person as may be entitled
thereto, all amounts otherwise payable to the Company or such successor, as the
case may be, on exercise of this Warrant pursuant to this Section 1.

     2.1  Delivery of Stock Certificates, etc. on Exercise. The Company agrees
          ------------------------------------------------
that the shares of Common Stock purchased upon exercise of this Warrant shall be
deemed to be issued to the holder hereof as the record owner of such shares as
of the close of business on the date on which this Warrant shall have been
surrendered and payment made for such shares as aforesaid. As soon as
practicable after the exercise of this Warrant in full or in part, and in any
event within 7 days thereafter, the Company at its expense (including the
payment by it of any applicable issue taxes) will cause to be issued in the name
of and delivered to the holder hereof, or as such holder (upon payment by such
holder of any applicable transfer taxes) may direct in compliance with
applicable Securities Laws, a certificate or certificates for the number of duly
and validly issued, fully paid and nonassessable shares of Common Stock (or
Other Securities) to which such holder shall be entitled on such exercise, plus,
in lieu of any fractional share to which such holder would otherwise be
entitled, cash equal to such fraction multiplied by the then Fair Market Value
of one full share, together with any other stock or other securities and
property (including cash, where applicable) to which such holder is entitled
upon such exercise pursuant to Section 1 or otherwise.

     2.2. Cashless Exercise.
          ------------------

          (a) Payment may be made either in (i) cash or by certified or official
bank check payable to the order of the Company equal to the applicable aggregate
Purchase Price, (ii) by delivery of Warrants, Common Stock and/or Common Stock
receivable upon exercise of the Warrants in accordance with Section (b) below,
or (iii) by a combination of any of the foregoing methods, for the number of
Common Shares specified in such form (as such exercise number shall be adjusted
to reflect any adjustment in the total number of shares of Common Stock issuable
to the holder per the terms of this Warrant) and the holder shall thereupon be
entitled to receive the number of duly authorized, validly issued, fully-paid
and non-assessable shares of Common Stock (or Other Securities) determined as
provided herein.

          (b) Notwithstanding any provisions herein to the contrary, if the Fair
Market Value of one share of Common Stock is greater than the Purchase Price (at
the date of calculation as set forth below), in lieu of exercising this Warrant
for cash, upon consent of the Company, the holder may elect to receive shares
equal to the value (as determined below) of this Warrant (or the portion thereof
being cancelled) by surrender of this Warrant at the principal office of the
Company together with the properly endorsed Subscription Form in which event the
Company shall issue to the holder a number of shares of Common Stock computed
using the following formula:

                 X=Y (A-B)
                    ---
                                                        A
                                                       ---

          Where  X=  the number of shares of Common Stock to be issued to the
                     holder

                 Y=  the number of shares of Common Stock purchasable under the
                     Warrant or, if only a portion of the Warrant is being
                     exercised, the portion of the Warrant being exercised (at
                     the date of such calculation)

                 A=  the Fair Market Value of one share of the Company's Common
                     Stock (at the date of such calculation)

                 B=  Purchase Price (as adjusted to the date of such
                     calculation)

     3.   Adjustment for Reorganization, Consolidation, Merger, etc.
          ---------------------------------------------------------

          3.1. Reorganization, Consolidation, Merger, etc. In case at any time
               ------------------------------------------
or from time to time, the Company shall (a) effect a reorganization, (b)
consolidate with or merge into any other person, or (c) transfer all or
substantially all of its properties or assets to any other person under any plan
or arrangement contemplating the dissolution of the Company, then, in each such
case, as a condition to the consummation of such a transaction, proper and
adequate provision shall be made by the Company whereby the holder of this
Warrant, on the exercise hereof as provided in Section 1 at any time after the
consummation of such reorganization, consolidation or merger or the effective
date of such dissolution, as the case may be, shall receive, in lieu of the
Common Stock (or Other Securities) issuable on such exercise prior to such
consummation or such effective date, the stock and other securities and property
(including cash) to which such holder would have been entitled upon such
consummation or in connection with such dissolution, as the case may be, if such
holder had so exercised this Warrant, immediately prior thereto, all subject to
further adjustment thereafter as provided in Section 4.

          3.2. Dissolution. In the event of any dissolution of the Company
               -----------
following the transfer of all or substantially all of its properties or assets,
the Company, prior to such dissolution, shall at its expense deliver or cause to
be delivered the stock and other securities and property (including cash, where
applicable) receivable by the holders of the Warrants after the effective date
of such dissolution pursuant to this Section 3 to a bank or trust company having
its principal office in New York, NY, as trustee for the holder or holders of
the Warrants.

          3.3. Continuation of Terms. Upon any reorganization, consolidation,
               ---------------------
merger or transfer (and any dissolution following any transfer) referred to in
this Section 3, this Warrant shall continue in full force and effect and the
terms hereof shall be applicable to the shares of stock and other securities and
property receivable on the exercise of this Warrant after the consummation of
such reorganization, consolidation or merger or the effective date of
dissolution following any such transfer, as the case may be, and shall be
binding upon the issuer of any such stock or other securities, including, in the
case of any such transfer, the person acquiring all or substantially all of the
properties or assets of the Company, whether or not such person shall have
expressly assumed the terms of this Warrant as provided in Section 4.  In the
event this Warrant does not continue in full force and effect after the
consummation of the transaction described in this Section 3, then only in such
event will the Company's securities and property (including cash, where
applicable) receivable by the holders of the Warrants be delivered to the
Trustee as contemplated by Section 3.2.

          3.4. Share Issuance.   Except for the Excepted Issuances as described
               --------------
in Section 11 of the Subscription Agreement, if the Company at any time shall
issue any shares of Common Stock prior to the complete exercise of this Warrant
for a consideration less than the Purchase Price that would be in effect at the
time of such issue, then, and thereafter successively upon each such issue, the
Purchase Price shall be reduced as follows: (i) the number of shares of Common
Stock outstanding immediately prior to such issue shall be multiplied by the
Purchase Price in effect at the time of such issue and the product shall be
added to the aggregate consideration, if any, received by the Company upon such
issue of additional shares of Common Stock; and (ii) the sum so obtained shall
be divided by the number of shares of Common Stock outstanding immediately after
such issue.  The resulting quotient shall be the adjusted Purchase Price.  For
purposes of this adjustment, the issuance of any security of the Company
carrying the right to convert such security into shares of Common Stock or of
any warrant, right or option to purchase Common Stock shall result in an
adjustment to the Purchase Price upon the issuance of shares of Common Stock
upon exercise of such conversion or purchase rights.

                                       12
<PAGE>

     4.   Extraordinary Events Regarding Common Stock. In the event that the
          -------------------------------------------
Company shall (a) issue additional shares of the Common Stock as a dividend or
other distribution on outstanding Common Stock, (b) subdivide its outstanding
shares of Common Stock, or (c) combine its outstanding shares of the Common
Stock into a smaller number of shares of the Common Stock, then, in each such
event, the Purchase Price shall, simultaneously with the happening of such
event, be adjusted by multiplying the then Purchase Price by a fraction, the
numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to such event and the denominator of which shall be the number
of shares of Common Stock outstanding immediately after such event, and the
product so obtained shall thereafter be the Purchase Price then in effect. The
Purchase Price, as so adjusted, shall be readjusted in the same manner upon the
happening of any successive event or events described herein in this Section 4.
The number of shares of Common Stock that the holder of this Warrant shall
thereafter, on the exercise hereof as provided in Section 1, be entitled to
receive shall be increased to a number determined by multiplying the number of
shares of Common Stock that would otherwise (but for the provisions of this
Section 4) be issuable on such exercise by a fraction of which (a) the numerator
is the Purchase Price that would otherwise (but for the provisions of this
Section 4) be in effect, and (b) the denominator is the Purchase Price in effect
on the date of such exercise.

     5.   Certificate as to Adjustments. In each case of any adjustment or
          -----------------------------
readjustment in the shares of Common Stock (or Other Securities) issuable on the
exercise of the Warrants, the Company at its expense will promptly cause its
Chief Financial Officer or other appropriate designee to compute such adjustment
or readjustment in accordance with the terms of the Warrant and prepare a
certificate setting forth such adjustment or readjustment and showing in detail
the facts upon which such adjustment or readjustment is based, including a
statement of (a) the consideration received or receivable by the Company for any
additional shares of Common Stock (or Other Securities) issued or sold or deemed
to have been issued or sold, (b) the number of shares of Common Stock (or Other
Securities) outstanding or deemed to be outstanding, and (c) the Purchase Price
and the number of shares of Common Stock to be received upon exercise of this
Warrant, in effect immediately prior to such adjustment or readjustment and as
adjusted or readjusted as provided in this Warrant. The Company will forthwith
mail a copy of each such certificate to the holder of the Warrant and any
Warrant agent of the Company (appointed pursuant to Section 11 hereof).

     6.   Reservation of Stock, etc. Issuable on Exercise of Warrant; Financial
          ---------------------------------------------------------------------
Statements. The Company will at all times reserve and keep available, solely for
----------
issuance and delivery on the exercise of the Warrants, all shares of Common
Stock (or Other Securities) from time to time issuable on the exercise of the
Warrant.  This Warrant entitles the holder hereof to receive copies of all
financial and other information distributed or required to be distributed to the
holders of the Company's Common Stock.

     7.   Assignment; Exchange of Warrant. Subject to compliance with applicable
          -------------------------------
Securities laws, this Warrant, and the rights evidenced hereby, may be
transferred by any registered holder hereof (a "Transferor") with respect to any
or all of the Shares. On the surrender for exchange of this Warrant, with the
Transferor's endorsement in the form of Exhibit B attached hereto (the
Transferor Endorsement Form") and together with evidence reasonably satisfactory
to the Company demonstrating compliance with applicable Securities Laws, the
Company at its expense but with payment by the Transferor of any applicable
transfer taxes) will issue and deliver to or on the order of the Transferor
thereof a new Warrant or Warrants of like tenor, in the name of the Transferor
and/or the transferee(s) specified in such Transferor Endorsement Form (each a
"Transferee"), calling in the aggregate on the face or faces thereof for the
number of shares of Common Stock called for on the face or faces of the Warrant
so surrendered by the Transferor.

     8.   Replacement of Warrant. On receipt of evidence reasonably satisfactory
          ----------------------
to the Company of the loss, theft, destruction or mutilation of this Warrant
and, in the case of any such loss, theft or destruction of this

                                       13
<PAGE>

Warrant, on delivery of an indemnity agreement or security reasonably
satisfactory in form and amount to the Company or, in the case of any such
mutilation, on surrender and cancellation of this Warrant, the Company at its
expense will execute and deliver, in lieu thereof, a new Warrant of like tenor.

     9.   Subscription Agreement.  This Warrant is issued pursuant to a
          ----------------------
Subscription Agreement entered into by the Company and Subscribers of the
Company's 8% Convertible Notes at or prior to the issue date of this Warrant.
The terms of the Subscription Agreement are incorporated herein by this
reference.

     10.  Maximum Exercise.   The Holder shall not be entitled to exercise this
          ----------------
Warrant on an exercise date, in connection with that number of shares of Common
Stock which would be in excess of the sum of (i) the number of shares of Common
Stock beneficially owned by the Holder and its affiliates on an exercise date,
and (ii) the number of shares of Common Stock issuable upon the exercise of this
Warrant with respect to which the determination of this proviso is being made on
an exercise date, which would result in beneficial ownership by the Holder and
its affiliates of more than 4.99% of the outstanding shares of Common Stock of
the Company on such date.  For the purposes of the proviso to the immediately
preceding sentence, beneficial ownership shall be determined in accordance with
Section 13(d) of the Securities Exchange Act of 1934, as amended, and Regulation
13d-3 thereunder.  Subject to the foregoing, the Holder shall not be limited to
aggregate exercises which would result in the issuance of more than 4.99%.  The
restriction described in this paragraph may be revoked upon an Event of Default
under the Note.  The Holder may allocate which of the equity of the Company
deemed beneficially owned by the Subscriber shall be included in the 4.99%
amount described above and which shall be allocated to the excess above 4.99%.

     11.  Warrant Agent.  The Company may, by written notice to the each holder
          -------------
of the Warrant, appoint an agent for the purpose of issuing Common Stock (or
Other Securities) on the exercise of this Warrant pursuant to Section 1,
exchanging this Warrant pursuant to Section 7, and replacing this Warrant
pursuant to Section 8, or any of the foregoing, and thereafter any such
issuance, exchange or replacement, as the case may be, shall be made at such
office by such agent.

     12.  Transfer on the Company's Books.  Until this Warrant is transferred on
          -------------------------------
the books of the Company, the Company may treat the registered holder hereof as
the absolute owner hereof for all purposes, notwithstanding any notice to the
contrary.

     13.  Notices, etc.  All notices and other communications from the Company
          ------------
to the holder of this Warrant shall be mailed by first class registered or
certified mail, postage prepaid, at such address as may have been furnished to
the Company in writing by such holder or, until any such holder furnishes to the
Company an address, then to, and at the address of, the last holder of this
Warrant who has so furnished an address to the Company.

     14.  Miscellaneous. This Warrant and any term hereof may be changed,
          -------------
waived, discharged or terminated only by an instrument in writing signed by the
party against which enforcement of such change, waiver, discharge or termination
is sought. This Warrant shall be construed and enforced in accordance with and
governed by the laws of New York.  Any dispute relating to this Warrant shall be
adjudicated in New York State.  The headings in this Warrant are for purposes of
reference only, and shall not limit or otherwise affect any of the terms hereof.
The invalidity or unenforceability of any provision hereof shall in no way
affect the validity or enforceability of any other provision.
