             TO PURCHASE [       ] SHARES OF COMMON STOCK OF

                   HAWAIIAN NATURAL WATER COMPANY, INC.

          THIS CERTIFIES that, for value received, [          } or his assigns
(collectively, the "Holder"), is entitled, upon the terms and subject to the
conditions hereinafter set forth, at any time after October 1, 1999 (the
"Initial Exercise Date") and on or prior to the close of business on September

purchase from HAWAIIAN NATURAL WATER COMPANY, INC., a corporation incorporated
in Hawaii (the "Company"), up to [                                    (       )
shares (the "Warrant Shares") of Common Stock, no par value per share, of the
Company (the "Common Stock").  The purchase price of one share of Common Stock
(the "Exercise Price") under this Warrant shall be One Dollar ($1.00). The
Exercise Price and the number of shares for which the Warrant is exercisable
shall be subject to adjustment as provided herein. This Warrant is being issued
in connection with that certain Subscription Agreement between the Holder and
the Company dated as of September   , 1999 (the "Purchase Agreement") and is
subject to its terms and conditions.  In the event of any conflict between the
terms of this Warrant and the Purchase Agreement, the Purchase Agreement shall
control.

          1.   TITLE OF WARRANT.  Prior to the expiration hereof and subject
to compliance with applicable laws, this Warrant and all rights hereunder are
transferable, in whole or in part, at the office or agency of the Company by
the holder hereof in person or by duly authorized attorney, upon surrender of
this Warrant together with the Assignment Form annexed hereto properly
endorsed.

<PAGE>

          2.   AUTHORIZATION OF SHARES.  The Company covenants that all
shares of Common Stock which may be issued upon the exercise of rights
represented by this Warrant will, upon exercise of the rights represented by
this Warrant, be duly authorized, validly issued, fully paid and
nonassessable and free from all taxes, liens and charges in respect of the
issue thereof (other than taxes in respect of any transfer occurring
contemporaneously with such issue).

          3.   EXERCISE OF WARRANT.  Except as provided in Section 4 herein,
exercise of the purchase rights represented by this Warrant may be made at
any time or times on or after the Initial Exercise Date, and before the close
of business on the Termination Date, by the delivery of the Notice of
Exercise Form annexed hereto duly executed, at the office of the Company (or
such other office or agency of the Company as it may designate by notice in
writing to the registered holder hereof at the address of such holder
appearing on the books of the Company) and upon payment to the Company of the
Exercise Price for the shares thereby purchased by wire transfer or cashier's
check drawn on a United States bank, the Holder shall be entitled to receive
a certificate for the number of shares of Common Stock so purchased.
Certificates for shares purchased hereunder shall be delivered to the holder
hereof promptly after the date on which this Warrant shall have been
exercised as aforesaid. This Warrant shall be deemed to have been exercised
and such certificate or certificates shall be deemed to have been issued, and
 the Holder or any other person so designated to be named therein shall be
deemed to have become a holder of record of such shares for all purposes, as
of the date the Warrant has been exercised by payment to the Company of the
Exercise Price and all taxes required to be paid by Holder, if any, pursuant
to Section 5 prior to the issuance of such shares, have been paid.

          4.   NO FRACTIONAL SHARES OR SCRIP.  No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant.  As to any fraction of a share which the Holder would otherwise be
entitled to purchase upon such exercise, the Company shall pay a cash
adjustment in respect of such final fraction in an amount equal to the
Exercise Price.

          5.   CHARGES, TAXES AND EXPENSES.  Issuance of certificates for
shares of Common Stock upon the exercise of this Warrant shall be made
without charge to the Holder for any issue or transfer tax or other
incidental expense in respect of the issuance of such certificate, all of
which taxes and expenses shall be paid by the Company, and such certificates
shall be issued in the name of the holder of this Warrant or in such name or
names as may be directed by the holder of this Warrant; provided, however,
that in the event certificates for shares of Common Stock are to be issued in
a name other than the name of the holder of this Warrant, this Warrant when
surrendered for exercise shall be accompanied by the Assignment Form attached
hereto duly executed by the Holder, and the Company may require, as a
condition thereto, the payment of a sum sufficient to reimburse it for any
transfer tax incidental thereto.

          6.   CLOSING OF BOOKS.  The Company will not close its shareholder
books or records in any manner which prevents the timely exercise of this
Warrant.

<PAGE>

          7.   TRANSFER, DIVISION AND COMBINATION.  (a) Subject to compliance
with any applicable securities laws, transfer of this Warrant and all rights
hereunder, in whole or in part, shall be registered on the books of the
Company to be maintained for such purpose, upon surrender of this Warrant at
the principal office of the Company, together with a written assignment of
this Warrant substantially in the form attached hereto duly executed by the
Holder or its agent or attorney and funds sufficient to pay any transfer
taxes payable upon the making of such transfer.  Upon such surrender and, if
required, such payment, the Company shall execute and deliver a new Warrant
or Warrants in the name of the assignee or assignees and in the denomination
specified in such instrument of assignment, and shall issue to the assignor a
new Warrant evidencing the portion of this Warrant not so assigned, and this
Warrant shall promptly be cancelled.  A Warrant, if properly assigned, may be
exercised by a new holder for the purchase of shares of Common Stock without
having a new Warrant issued.

               (b)  This Warrant may be divided or combined with other
Warrants upon presentation hereof at the aforesaid office of the Company,
together with a written notice specifying the names and denominations in
which new Warrants are to be issued, signed by the Holder or its agent or
attorney.  Subject to compliance with Section 7(a), as to any transfer which
may be involved in such division or combination, the Company shall execute
and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants
to be divided or combined in accordance with such notice.

               (c)  The Company agrees to maintain, at its aforesaid office,
books for the registration and the registration of transfer of the Warrants.

          8.   NO RIGHTS AS SHAREHOLDER UNTIL EXERCISE.  This Warrant does
not entitle the holder hereof to any voting rights or other rights as a
shareholder of the Company prior to the exercise hereof.  Upon the surrender
of this Warrant and the payment of the aggregate Exercise Price, the Warrant
Shares so purchased shall be and be deemed to be issued to the Holder as the
record owner of such shares as of the close of business on the later of the
date of such surrender or payment.

          9.   LOSS, THEFT, DESTRUCTION OR MUTILATION OF WARRANT.  The
Company represents and warrants that upon receipt by the Company of evidence
reasonably satisfactory to it of the loss, theft, destruction or mutilation
of this Warrant certificate or any stock certificate relating to the Warrant
Shares, and in case of loss, theft or destruction, of indemnity or security
reasonably satisfactory to it, and upon surrender and cancellation of such
Warrant or stock certificate, if mutilated, the Company will make and deliver
a new Warrant or stock certificate of like tenor and dated as of such
cancellation, in lieu of such Warrant or stock certificate.

          10.  SATURDAYS, SUNDAYS, HOLIDAYS, ETC.  If the last or appointed
day for the taking of any action or the expiration of any right required or
granted herein shall be a Saturday, Sunday or a legal holiday, then such
action may be taken or such right may be exercised on the next succeeding day
not a Saturday, Sunday or legal holiday.

<PAGE>

          11.  ADJUSTMENTS OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES.
(a) STOCK SPLITS, ETC. The number and kind of securities purchasable upon the
exercise of this Warrant and the Exercise Price shall be subject to
adjustment from time to time upon the happening of any of the following.  In
case the Company shall (i) pay a dividend in shares of Common Stock or make a
distribution in shares of Common Stock to holders of its outstanding Common
Stock, (ii) subdivide its outstanding shares of Common Stock into a greater
number of shares of Common Stock, (iii) combine its outstanding shares of
Common Stock into a smaller number of shares of Common Stock or (iv) issue
any shares of its capital stock in a reclassification of the Common Stock,
then the number of Warrant Shares purchasable upon exercise of this Warrant
immediately prior thereto shall be adjusted so that the holder of this
Warrant shall be entitled to receive the kind and number of Warrant Shares or
other securities of the Company which he would have owned or have been
entitled to receive had such Warrant been exercised in advance thereof.  Upon
each such adjustment of the kind and number of Warrant Shares or other
securities of the Company which are purchasable hereunder, the holder of this
Warrant shall thereafter be entitled to purchase the number of Warrant Shares
or other securities resulting from such adjustment at an Exercise Price per
such Warrant Share or other security obtained by multiplying the Exercise
Price in effect immediately prior to such adjustment by the number of Warrant
Shares purchasable pursuant hereto immediately prior to such adjustment and
dividing by the number of Warrant Shares or other securities of the Company
resulting from such adjustment.  An adjustment made pursuant to this
paragraph shall become effective immediately after the effective date of such
event retroactive to the record date, if any, for such event.

               (b)  REORGANIZATION, RECLASSIFICATION, MERGER, CONSOLIDATION
OR DISPOSITION OF ASSETS.  In case the Company shall reorganize its capital,
reclassify its capital stock, consolidate or merge with or into another
corporation (where the Company is not the surviving corporation or where
there is a change in or distribution with respect to the Common Stock of the
Company), or sell, transfer or otherwise dispose of all or substantially all
its property, assets or business to another corporation and, pursuant to the
terms of such reorganization, reclassification, merger, consolidation or
disposition of assets, shares of common stock of the successor or acquiring
corporation, or any cash, shares of stock or other securities or property of
any nature whatsoever (including warrants or other subscription or purchase
rights) in addition to or in lieu of common stock of the successor or
acquiring corporation ("Other Property"), are to be received by or
distributed to the holders of Common Stock of the Company, then the Holder
shall have the right thereafter to receive, upon exercise of this Warrant,
the number of shares of common stock of the successor or acquiring
corporation or of the Company, if it is the surviving corporation, and Other
Property receivable upon or as a result of such reorganization,
reclassification, merger, consolidation or disposition of assets by a holder
of the number of shares of Common Stock for which this Warrant is exercisable
immediately prior to such event.  In case of any such reorganization,
reclassification, merger, consolidation or disposition of assets, the
successor or acquiring corporation (if other than the Company) shall
expressly assume the due and punctual observance and performance of each and
every covenant and condition of this Warrant to be performed and observed by
the Company and all the obligations and liabilities hereunder, subject to
such modifications as may be deemed appropriate (as determined by resolution
of the Board of Directors of the Company) in order to provide for adjustments
of shares of Common Stock for which this Warrant is exercisable which shall
be as nearly

<PAGE>

equivalent as practicable to the adjustments provided for in this Section 11.
For purposes of this Section 11, "common stock of the successor or acquiring
corporation" shall include stock of such corporation of any class which is
not preferred as to dividends or assets over any other class of stock of such
corporation and which is not subject to redemption and shall also include any
evidences of indebtedness, shares of stock or other securities which are
convertible into or exchangeable for any such stock, either immediately or
upon the arrival of a specified date or the happening of a specified event
and any warrants or other rights to subscribe for or purchase any such stock.
The foregoing provisions of this Section 11 shall similarly apply to
successive reorganizations, reclassifications, mergers, consolidations or
disposition of assets.

          12.  VOLUNTARY ADJUSTMENT BY THE COMPANY.  The Company may at any
time during the term of this Warrant, reduce the then current Exercise Price
to any amount and for any period of time deemed appropriate by the Board of
Directors of the Company.

          13.  NOTICE OF ADJUSTMENT.  Whenever the number of Warrant Shares
or number or kind of securities or other property purchasable upon the
exercise of this Warrant or the Exercise Price is adjusted, as herein
provided, the Company shall promptly mail by registered or certified mail,
return receipt requested, to the Holder notice of such adjustment or
adjustments setting forth the number of Warrant Shares (and other securities
or property) purchasable upon the exercise of this Warrant and the Exercise
Price of such Warrant Shares (and other securities or property) after such
adjustment, setting forth a brief statement of the facts requiring such
adjustment and setting forth the computation by which such adjustment was
made.  Such notice, in absence of manifest error, shall be conclusive
evidence of the correctness of such adjustment.

          14.  NOTICE OF CORPORATE ACTION.  If at any time:

               (a)  the Company shall take a record of the holders of its
Common Stock for the purpose of entitling them to receive a dividend or other
distribution, or any right to subscribe for or purchase any evidences of its
indebtedness, any shares of stock of any class or any other securities or
property, or to receive any other right, or

               (b)  there shall be any capital reorganization of the Company,
any reclassification or recapitalization of the capital stock of the Company
or any consolidation or merger of the Company with, or any sale, transfer or
other disposition of all or substantially all the property, assets or
business of the Company to, another corporation or,

               (c)  there shall be a voluntary or involuntary dissolution,
liquidation or winding up of the Company;

then, in any one or more of such cases, the Company shall give to the Holder
(i) at least five (5) business days' prior written notice of the date on
which a record date shall be selected for such dividend, distribution or
right or for determining rights to vote in respect of any such
reorganization, reclassification, merger, consolidation, sale, transfer,
disposition, liquidation or winding up, and (ii) in the case of any such
reorganization, reclassification, merger,

<PAGE>

consolidation, sale, transfer, disposition, dissolution, liquidation or
winding up, at least five (5) business days' prior written notice of the date
when the same shall take place.  Such notice in accordance with the foregoing
clause also shall specify (i) the date on which any such record is to be
taken for the purpose of such dividend, distribution or right, the date on
which the holders of Common Stock shall be entitled to any such dividend,
distribution or right, and the amount and character thereof, and (ii) the
date on which any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, dissolution, liquidation or
winding up is to take place and the time, if any such time is to be fixed, as
of which the holders of Common Stock shall be entitled to exchange their
shares of Common Stock for securities or other property deliverable upon such
disposition, dissolution, liquidation or winding up.  Each such written
notice shall be sufficiently given if addressed to the Holder at the last
address of the Holder appearing on the books of the Company and delivered in
accordance with Section 16(d).

          15.  AUTHORIZED SHARES.  The Company covenants that during the
period the Warrant is outstanding, it will reserve from its authorized and
unissued Common Stock a sufficient number of shares to provide for the
issuance of the Warrant Shares upon the exercise of any purchase rights under
this Warrant.  The Company further covenants that its issuance of this
Warrant shall constitute full authority to its officers who are charged with
the duty of executing stock certificates to execute and issue the necessary
certificates for the Warrant Shares upon the exercise of the purchase rights
under this Warrant.  The Company will take all such reasonable action as may
be necessary to assure that such Warrant Shares may be issued as provided
herein without violation of any applicable law or regulation, or of any
requirements of Nasdaq or any domestic securities exchange upon which the
Common Stock may be listed.

                    The Company shall not by any action, including, without
limitation, amending its certificate of incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue
or sale of securities or any other voluntary action, avoid or seek to avoid
the observance or performance of any of the terms of this Warrant, but will
at all times in good faith assist in the carrying out of all such terms and
in the taking of all such actions as may be necessary or appropriate to
protect the rights of the Holder against impairment.  Without limiting the
generality of the foregoing, the Company will (a) not increase the par value
of any shares of Common Stock receivable upon the exercise of this Warrant
above the amount payable therefor upon such exercise immediately prior to
such increase in par value, (b) take all such action as may be necessary or
appropriate in order that the Company may validly and legally issue fully
paid and nonassessable shares of Common Stock upon the exercise of this
Warrant, and (c) use its best efforts to obtain all such authorizations,
exemptions or consents from any public regulatory body having jurisdiction
thereof as may be necessary to enable the Company to perform its obligations
under this Warrant.

                    Before taking any action which would cause an adjustment
reducing the current Exercise Price below the then par value, if any, of the
shares of Common Stock issuable upon exercise of the Warrants, the Company
shall take any corporate action which may be necessary in order that the
Company may validly and legally issue fully paid and non-assessable shares of
such Common Stock at such adjusted Exercise Price.

<PAGE>

                    Before taking any action which would result in an
adjustment in the number of shares of Common Stock for which this Warrant is
exercisable or in the Exercise Price, the Company shall obtain all such
authorizations or exemptions thereof, or consents thereto, as may be
necessary from any public regulatory body or bodies having jurisdiction
thereof.

          16.  REDEMPTION.  This Warrant may be redeemed, at the option of
the Company, in whole or in part, at any time, upon thirty (30) days' prior
written notice to the Holder (the "Redemption Notice"), in the event that the
average closing bid price of the Common Stock, as reported by Nasdaq (or any
national or regional stock exchange on which the Common Stock may then be
listed) for a period of ten (10) trading days immediately preceding the
delivery date of the Redemption Notice, is at least 200% of the then exercise
price of this Warrant, as adjusted as provided above.  The redemption price
shall be $.05, multiplied by the number of Warrant Shares with respect to
which the Redemption Notice applies (the "Redemption Price").  This Warrant
shall be fully exercisable by the Holder until the date fixed for redemption
(the "Redemption Date").  On and after the Redemption Date, the Holder shall
have no rights with respect to that portion of this Warrant called for
redemption, except the right to receive the Redemption price, upon surrender
of this Warrant.

          17.  MISCELLANEOUS.

               (a)  JURISDICTION. This Warrant shall be binding upon any
successors or assigns of the Company.  This Warrant shall constitute a
contract under the laws of Hawaii,  without regard to its conflict of law,
principles or rules, and be subject to arbitration pursuant to the terms set
forth in the Agreement.

               (b)  RESTRICTIONS.  The Holder acknowledges that the Warrant
Shares acquired upon the exercise of this Warrant, if not registered, will
have restrictions upon resale imposed by state and federal securities laws
and by the Agreement.

               (c)  NONWAIVER AND EXPENSES.  No course of dealing or any
delay or failure to exercise any right hereunder on the part of the Holder
shall operate as a waiver of such right or otherwise prejudice the Holder's
rights, powers or remedies, notwithstanding all rights hereunder terminate on
the Termination Date.  If the Company fails to make, when due, any payments
provided for hereunder, or fails to comply with any other provision of this
Warrant, the Company shall pay to the Holder such amounts as shall be
sufficient to cover any costs and expenses including, but not limited to,
reasonable attorneys' fees, including those of appellate proceedings,
incurred by the Holder in collecting any amounts due pursuant hereto or in
otherwise enforcing any of its rights, powers or remedies hereunder.

<PAGE>

               (d)  NOTICES.  Any notice, request or other document required
or permitted to be given or delivered to the Holder by the Company shall be
delivered in accordance with the notice provisions of the Agreement.

               (e)  LIMITATION OF LIABILITY.  No provision hereof, in the
absence of affirmative action by the Holder to purchase shares of Common
Stock, and no enumeration herein of the rights or privileges of the Holder,
shall give rise to any liability of the Holder for the purchase price of any
Common Stock or as a stockholder of the Company, whether such liability is
asserted by the Company or by creditors of the Company.

               (f)  REMEDIES.  The Holder, in addition to being entitled to
exercise all rights granted by law, including recovery of damages, will be
entitled to specific performance of its rights under this Warrant.  The
Company agrees that monetary damages would not be adequate compensation for
any loss incurred by reason of a breach by it of the provisions of this
Warrant and hereby agrees to waive the defense in any action for specific
performance that a remedy at law would be adequate.

               (g)  SUCCESSORS AND ASSIGNS.  Subject to applicable securities
laws, this Warrant and the rights and obligations evidenced hereby shall
inure to the benefit of and be binding upon the successors of the Company and
the successors and permitted assigns of the Holder.  The provisions of this
Warrant are intended to be for the benefit of all Holders from time to time
of this Warrant and shall be enforceable by any such Holder or holder of
Warrant Stock.

               (h)  COOPERATION.  The Company shall cooperate with the Holder
in supplying such information as may be reasonably necessary for the Holder
to complete and file any information reporting forms presently or hereafter
required by the Commission as a condition to the availability of an exemption
from the Securities Act for the sale of any Warrant or Restricted Common
Stock.

               (i)  INDEMNIFICATION.  The Company agrees to indemnify and
hold harmless the Holder from and against any liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, claims, costs,
attorneys' fees, expenses and disbursements of any kind which may be imposed
upon, incurred by or asserted against the Holder in any manner relating to or
arising out of any failure by the Company to perform or observe in any
material respect any of its covenants, agreements, undertakings or
obligations set forth in this Warrant; PROVIDED, HOWEVER, that the Company
will not be liable hereunder to the extent that any liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, claims, costs,
attorneys' fees, expenses or disbursements are found in a final
non-appealable judgment by a court to have resulted from the Holder's
negligence, bad faith or willful misconduct in its capacity as a stockholder
or warrantholder of the Company.

               (j)  AMENDMENT.  This Warrant may be modified or amended or
the provisions hereof waived with the written consent of the Company and the
Holder.

<PAGE>

               (k)  SEVERABILITY.  Wherever possible, each provision of this
Warrant shall be interpreted in such manner as to be effective and valid
under applicable law, but if any provision of this Warrant shall be
prohibited by or invalid under applicable law, such provision shall be
ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provisions or the remaining provisions of
this Warrant.

               (l)  HEADINGS.  The headings used in this Warrant are for the
convenience of reference only and shall not, for any purpose, be deemed a
part of this Warrant.

               IN WITNESS WHEREOF, the Company has caused this Warrant to be
executed by its officer thereunto duly authorized.
