                      JACOBSON RESONANCE ENTERPRISES, INC.

                                     WARRANT
                                     -------

                            Dated: December 18, 2001

     JACOBSON RESONANCE ENTERPRISES, INC. a corporation organized under the laws
of the State of Nevada (the "Company"), hereby certifies that, for value
received from TECINVEST SERVICES, INC. ("Holder"), is entitled, subject to the
terms set forth below, to purchase from the Company up to a total of Five
Hundred Thousand (500,000) shares of Common Stock, $.001 par value per share
(the "Common Stock"), of the Company (each such share, a "Warrant Share" and all
such shares, the "Warrant Shares") at an exercise price equal to the lesser of
(a) 110% of the average closing bid price for the five (5) Trading Days
immediately preceding, but not including, December 18, 2001 or (b) the closing
bid price on the 180th calendar day following December 18, 2001, (or the next
Trading Day if such date is not a Trading Day) or (c) the closing bid price on
the 365th calendar day following December 18, 2001, (or the next Trading Day if
such date is not a Trading Day) (as adjusted from time to time as provided in
Section 8, the "Exercise Price"). The Warrant will be immediately exercisable on
a cash or cashless basis, and may be exercised anytime after its issuance. This
Warrant will expire on the fourth (4th) anniversary of its issuance (the
"Expiration Date"), and is subject to the following terms and conditions:

     1. Registration of Warrant.  The Company shall register this Warrant, upon
records to be maintained by the Company for that purpose (the "Warrant
Register"), in the name of the record Holder hereof from time to time. The
Company may deem and treat the registered Holder of this Warrant as the absolute
owner hereof for the purpose of any exercise hereof or any distribution to the
Holder, and for all other purposes, and the Company shall not be affected by
notice to the contrary.

     2. Registration of Transfers and Exchanges.

     (a) The Company shall register the transfer of any portion of this Warrant
in the Warrant Register, upon surrender of this Warrant to the Transfer Agent or
to the Company at the office specified in or pursuant to Section 3(b). Upon any
such registration or transfer, a new warrant to purchase Common Stock, in
substantially the form of this Warrant (any such new warrant, a "New Warrant"),
evidencing the portion of this Warrant so transferred shall be issued to the
transferee and a New Warrant evidencing the remaining portion of this Warrant
not so transferred, if any, shall be issued to the transferring Holder. The
acceptance of the New Warrant by the transferee thereof shall be deemed the
acceptance of such transferee of all of the rights and obligations of a holder
of a Warrant.

     (b) This Warrant is exchangeable, upon the surrender hereof by the Holder
to the office of the Company specified in or pursuant to Section 3(b) for one or
more New Warrants, evidencing in the aggregate the right to purchase the number
of Warrant Shares which may then be purchased hereunder. Any such New Warrant
will be dated the date of such exchange.

     3. Duration and Exercise of Warrants.

     (a) This Warrant shall be exercisable by the registered Holder on any
business day before 5:00 P.M., New York City time, at any time and from time to
time on or after the date hereof to and including the Expiration Date. At 5:00
P.M., New York City time on the Expiration Date, the portion of this Warrant not
exercised prior thereto shall be and become void and of no value. Prior to the
Expiration Date, the Company may not call or otherwise redeem this Warrant
without the prior written consent of the Holder.

     (b) Subject to Sections 2(b), 6 and 10, upon surrender of this Warrant,
with the Form of Election to Purchase attached hereto duly completed and signed,
to the Company at its address for notice set forth in Section 12 and upon
payment of the Exercise Price multiplied by the number of Warrant Shares that
the Holder intends to purchase hereunder, in the manner provided hereunder, all
as specified by the Holder in the Form of Election to Purchase, the Company
shall promptly (but in no event later than 3 business days after the Date of
Exercise (as defined herein)) issue or cause to be issued and cause to be
delivered to or upon the written order of the Holder and in such name or names
as the Holder may designate, a certificate for the Warrant Shares issuable upon
such exercise, free of restrictive legends except (i) either in the event that a
registration statement covering the resale of the Warrant Shares and naming the
Holder as a selling stockholder thereunder is not then effective or the Warrant
Shares are not freely transferable without volume restrictions pursuant to Rule
144(k) promulgated under the Securities Act of 1933, as amended (the "Securities
Act"), or (ii) if this Warrant shall have been issued pursuant to a written
agreement between the original Holder and the Company, as required by such
agreement. Any person so designated by the Holder to receive Warrant Shares
shall be deemed to have become holder of record of such Warrant Shares as of the
Date of Exercise (as defined in this subsection) of this Warrant.
     A "Date of Exercise" means the date on which the Company shall have
received (i) this Warrant (or any New Warrant, as applicable), with the Form of
Election to Purchase attached hereto (or attached to such New Warrant)
appropriately completed and duly signed, and (ii) payment of the Exercise Price
for the number of Warrant Shares so indicated by the holder hereof to be
purchased.

     (c) This Warrant shall be exercisable, either in its entirety or, from time
to time, for a portion of the number of Warrant Shares. If less than all of the
Warrant Shares which may be purchased under this Warrant are exercised at any
time, the Company shall issue or cause to be issued, at its expense, a New
Warrant evidencing the right to purchase the remaining number of Warrant Shares
for which no exercise has been evidenced by this Warrant.
     In the event the Common Stock representing the Warrant Shares is not
delivered per the written instructions of the Purchaser, within 10 (ten)
business days after the Notice of Election and Warrant is received by the
Company (the "Delivery Date"), then in such event the Company shall pay to
Holder one-half percent (0.5%) in cash, of the dollar value of the Warrant
Shares to be issued per each day after the Delivery Date that the Warrant Shares
are not delivered.
     The Company acknowledges that its failure to deliver the Warrant Shares by
the Delivery Date will cause the Holder to suffer damages in an amount that will
be difficult to ascertain. Accordingly, the parties agree that it is appropriate
to include in this Warrant a provision for liquidated damages. The parties
acknowledge and agree that the liquidated damages provision set forth in this
section represents the parties' good faith effort to quantify such damages and,
as such, agree that the form and amount of such liquidated damages are
reasonable and will not constitute a penalty. The payment of liquidated damages
shall not relieve the Company from its obligations to deliver the Common Stock
pursuant to the terms of this Warrant.
     To the extent that the failure of the Company to issue the Common Stock
pursuant to this Section is due to the unavailability of authorized but unissued
shares of Common Stock, the provisions of this Section 3 shall not apply but
instead the provisions of Section 7 shall apply.
     The Company shall make any payments incurred under this Section 3 in
immediately available funds within ten (10) business days from the date of
issuance of the applicable Warrant Shares. Nothing herein shall limit Holder's
right to pursue actual damages or cancel the Notice of Election for the
Company's failure to issue and deliver Common Stock to the Holder within ten
(10) business days following the Delivery Date.

     4.  Piggyback Registration Rights. During the term of this Warrant, the
Company may not file any registration statement with the Securities and Exchange
Commission (other than registration statements of the Company filed on Form S-8
or Form S-4, each as promulgated under the Securities Act, pursuant to which the
Company is registering securities pursuant to a Company employee benefit plan or
pursuant to a merger, acquisition or similar transaction including supplements
thereto, but not additionally filed registration statements in respect of such
securities) at any time when there is not an effective registration statement
covering the resale of the Warrant Shares and naming the Holder as a selling
stockholder thereunder (unless the Warrant Shares are otherwise freely
transferable without volume restrictions pursuant to Rule 144(k) promulgated
under the Act), unless the Company provides the Holder with not less than twenty
(20) calendar days notice of its intention to file such registration statement
and provides the Holder the option to include any or all of the applicable
Warrant Shares therein. The piggyback registration rights granted to the Holder
pursuant to this Section shall continue until all of the Holder's Warrant Shares
have been sold in accordance with an effective registration statement or upon
the Expiration Date. The Company will pay all registration expenses in
connection therewith.

     5.  Payment of Taxes.  The Company will pay all documentary stamp taxes
attributable to the issuance of Warrant Shares upon the exercise of this
Warrant; provided, however, that the Company shall not be required to pay any
tax which may be payable in respect of any transfer involved in the registration
of any certificates for Warrant Shares or Warrants in a name other than that of
the Holder. The Holder shall be responsible for all other tax liability that may
arise as a result of holding or transferring this Warrant or receiving Warrant
Shares upon exercise hereof.

     6. Replacement of Warrant.  If this Warrant is mutilated, lost, stolen or
destroyed, the Company shall issue or cause to be issued in exchange and
substitution for and upon cancellation hereof, or in lieu of and substitution
for this Warrant, a New Warrant, but only upon receipt of evidence reasonably
satisfactory to the Company of such loss, theft or destruction and indemnity, if
requested, satisfactory to it. Applicants for a New Warrant under such
circumstances shall also comply with such other reasonable regulations and
procedures and pay such other reasonable charges as the Company may prescribe.

     7. Reservation of Warrant Shares. The Company covenants that it will at all
times reserve and keep available out of the aggregate of its authorized but
unissued Common Stock, solely for the purpose of enabling it to issue Warrant
Shares upon exercise of this Warrant as herein provided, the number of Warrant
Shares which are then issuable and deliverable upon the exercise of this entire
Warrant, free from preemptive rights or any other actual contingent purchase
rights of persons other than the Holder (taking into account the adjustments and
restrictions of Section 8). The Company covenants that all Warrant Shares that
shall be so issuable and deliverable shall, upon issuance and the payment of the
applicable Exercise Price in accordance with the terms hereof, be duly and
validly authorized, issued and fully paid and nonassessable. In the event the
Company fails to have sufficient authorized but unissued Common Stock to allow
for the issuance of Warrant Shares upon the exercise of the Warrant the Company
shall be liable for liquidated damages in the amount of 2% interest per thirty
calendar day period on the value of the Warrant Shares based on the closing bid
price of the Company's Common Stock on the business day prior to the Company's
receipt of its Election to Purchase. The damages shall accrue until the Common
Stock is issued.
     The Company acknowledges that its failure to reserve a sufficient number of
Warrant Shares as required in this Section 7, will cause the Holder to suffer
damages in an amount that will be difficult to ascertain. Accordingly, the
parties agree that it is appropriate to include in this Warrant a provision for
liquidated damages. The parties acknowledge and agree that the liquidated
damages provision set forth in this section represents the parties' good faith
effort to quantify such damages and, as such, agree that the form and amount of
such liquidated damages are reasonable and will not constitute a penalty. The
payment of liquidated damages shall not relieve the Company from its obligations
to deliver the Common Stock pursuant to the terms of this Warrant.
     It is the intention of the parties that interest payable under any of the
terms of this Warrant shall not exceed the maximum amount permitted under any
applicable law. If a law, which applies to this Warrant which sets the maximum
interest amount, is finally interpreted so that the interest in connection with
this Warrant exceeds the permitted limits, then: (1) any such interest shall be
reduced by the amount necessary to reduce the interest to the permitted limit;
and (2) any sums already collected (if any) from the Company which exceed the
permitted limits will be refunded to the Company. The Holder may choose to make
this refund by reducing the amount that the Company owes under this Warrant or
by making a direct payment to the Company. If a refund reduces the amount that
the Company owes the Holder, the reduction will be treated as a partial payment.
In case any provision of this Warrant is held by a court of competent
jurisdiction to be excessive in scope or otherwise invalid or unenforceable,
such provision shall be adjusted rather than voided, if possible, so that it is
enforceable to the maximum extent possible, and the validity and enforceability
of the remaining provisions of this Warrant will not in any way be affected or
impaired thereby.

     8. Certain Adjustments.  The Exercise Price and number of Warrant Shares
issuable upon exercise of this Warrant are subject to adjustment from time to
time as set forth in this Section 8; provided, that there shall be no adjustment
in the number of Warrant Shares issuable upon exercise of this Warrant upon any
adjustment of the Exercise Price pursuant to paragraph (d) of this Section 8.
Upon each such adjustment of the Exercise Price pursuant to this Section 8, the
Holder shall thereafter prior to the Expiration Date be entitled to purchase, at
the Exercise Price resulting from such adjustment, the number of Warrant Shares
obtained by multiplying the Exercise Price in effect immediately prior to such
adjustment by the number of Warrant Shares issuable upon exercise of this
Warrant immediately prior to such adjustment and dividing the product thereof by
the Exercise Price resulting from such adjustment.

     (a) If the Company, at any time while this Warrant is outstanding, (i)
shall pay a stock dividend (except scheduled dividends paid on outstanding
preferred stock as of the date hereof which contain a stated dividend rate) or
otherwise make a distribution or distributions on shares of its Common Stock or
on any other class of capital stock and not the Common Stock payable in shares
of Common Stock, (ii) subdivide outstanding shares of Common Stock into a larger
number of shares, or (iii) combine outstanding shares of Common Stock into a
smaller number of shares, the Exercise Price shall be multiplied by a fraction
of which the numerator shall be the number of shares of Common Stock (excluding
treasury shares, if any) outstanding before such event and of which the
denominator shall be the number of shares of Common Stock (excluding treasury
shares, if any) outstanding after such event. Any adjustment made pursuant to
this Section shall become effective immediately after the record date for the
determination of stockholders entitled to receive such dividend or distribution
and shall become effective immediately after the effective date in the case of a
subdivision or combination, and shall apply to successive subdivisions and
combinations.

     (b) In case of any reclassification of the Common Stock, any consolidation
or merger of the Company with or into another person, the sale or transfer of
all or substantially all of the assets of the Company or any compulsory share
exchange pursuant to which the Common Stock is converted into other securities,
cash or property, then the Holder shall have the right thereafter to exercise
this Warrant only into the shares of stock and other securities and property
receivable upon or deemed to be held by holders of Common Stock following such
reclassification, consolidation, merger, sale, transfer or share exchange, and
the Holder shall be entitled upon such event to receive such amount of
securities or property equal to the amount of Warrant Shares such Holder would
have been entitled to had such Holder exercised this Warrant immediately prior
to such reclassification, consolidation, merger, sale, transfer or share
exchange. The terms of any such consolidation, merger, sale, transfer or share
exchange shall include such terms so as to continue to give to the Holder the
right to receive the securities or property set forth in this Section 9(b) upon
any exercise following any such reclassification, consolidation, merger, sale,
transfer or share exchange.

     (c) If the Company, at any time while this Warrant is outstanding, shall
distribute to all holders of Common Stock (and not to holders of this Warrant)
evidences of its indebtedness or assets or rights or warrants to subscribe for
or purchase any security (excluding those referred to in Sections 8(a), (b) and
(d)), then in each such case the Exercise Price shall be determined by
multiplying the Exercise Price in effect immediately prior to the record date
fixed for determination of stockholders entitled to receive such distribution by
a fraction of which the denominator shall be the Exercise Price determined as of
the record date mentioned above, and of which the numerator shall be such
Exercise Price on such record date less the then fair market value at such
record date of the portion of such assets or evidence of indebtedness so
distributed applicable to one outstanding share of Common Stock as determined by
the Company's  independent  certified public accountants that regularly examines
the financial statements of the Company (an "Appraiser").

     (d) If, at any time while this Warrant is outstanding, the Company shall
issue or cause to be issued rights or warrants to acquire or otherwise sell or
distribute shares of Common Stock for a consideration per share less than the
Exercise Price then in effect, except for (i) the granting of options or
warrants to employees, officers, directors and the issuance of shares upon
exercise of options granted, under any stock option plan heretofore or
hereinafter duly adopted by the Company; (ii) shares issued upon exercise of any
currently outstanding warrants or options and upon conversion of any currently
outstanding convertible debenture or (iii) shares issued pursuant to the
Investment Agreement then, forthwith upon such issue or sale, the Exercise Price
shall be reduced to the price (calculated to the nearest cent) determined by
multiplying the Exercise Price in effect immediately prior thereto by a
fraction, the numerator of which shall be the sum of (i) the number of shares of
Common Stock outstanding immediately prior to such issuance, and (ii) the number
of shares of Common Stock which the aggregate consideration received (or to be
received, assuming exercise or conversion in full of such rights, warrants and
convertible securities) for the issuance of such additional shares of Common
Stock would purchase at the Exercise Price, and the denominator of which shall
be the sum of the number of shares of Common Stock outstanding immediately after
the issuance of such additional shares. Such adjustment shall be made
successively whenever such an issuance is made.

     (e) For the purposes of this Section 8, the following clauses shall also be
applicable:

     (i) Record Date.  In case the Company shall take a record of the holders of
its Common Stock for the purpose of entitling them (A) to receive a dividend or
other distribution payable in Common Stock or in securities convertible or
exchangeable into shares of Common Stock, or (B) to subscribe for or purchase
Common Stock or securities convertible or exchangeable into shares of Common
Stock, then such record date shall be deemed to be the date of the issue or sale
of the shares of Common Stock deemed to have been issued or sold upon the
declaration of such dividend or the making of such other distribution or the
date of the granting of such right of subscription or purchase, as the case may
be.

     (ii) Treasury Shares.  The number of shares of Common Stock outstanding at
any given time shall not include shares owned or held by or for the account of
the Company, and the disposition of any such shares shall be considered an issue
or sale of Common Stock.

     (f) All calculations under this Section 8 shall be made to the nearest cent
or the nearest 1/100th of a share, as the case may be.

     (g) Whenever the Exercise Price is adjusted pursuant to Section 8(c) above,
the Holder, after receipt of the determination by the Appraiser, shall have the
right to select an additional appraiser (which shall be a nationally recognized
accounting firm), in which case the adjustment shall be equal to the average of
the adjustments recommended by each of the Appraiser and such appraiser. The
Holder shall promptly mail or cause to be mailed to the Company, a notice
setting forth the Exercise Price after such adjustment and setting forth a brief
statement of the facts requiring such adjustment. Such adjustment shall become
effective immediately after the record date mentioned above.

     (h) If:

          (i)  the Company shall declare a dividend (or any other distribution)
               on its Common Stock; or

          (ii) the Company shall declare a special nonrecurring cash dividend on
               or a redemption of its Common Stock; or

          (iii)the Company shall authorize the granting to all holders of the
               Common Stock rights or warrants to subscribe for or purchase any
               shares of capital stock of any class or of any rights; or

          (iv) the approval of any stockholders of the Company shall be required
               in connection with any reclassification of the Common Stock of
               the Company, any consolidation or merger to which the Company is
               a party, any sale or transfer of all or substantially all of the
               assets of the Company, or any compulsory share exchange whereby
               the Common Stock is converted into other securities, cash or
               property; or

          (v)  the Company shall authorize the voluntary dissolution,
               liquidation or winding up of the affairs of the Company,

then the Company shall cause to be mailed to each Holder at their last addresses
as they shall appear upon the Warrant Register, at least 30 calendar days prior
to the applicable record or effective date hereinafter specified, a notice
stating (x) the date on which a record is to be taken for the purpose of such
dividend, distribution, redemption, rights or warrants, or if a record is not to
be taken, the date as of which the holders of Common Stock of record to be
entitled to such dividend, distributions, redemption, rights or warrants are to
be determined or (y) the date on which such reclassification, consolidation,
merger, sale, transfer or share exchange is expected to become effective or
close, and the date as of which it is expected that holders of Common Stock of
record shall be entitled to exchange their shares of Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer, share exchange, dissolution, liquidation
or winding up; provided, however, that the failure to mail such notice or any
defect therein or in the mailing thereof shall not affect the validity of the
corporate action required to be specified in such notice.

     9. Payment of Exercise Price. Payment of Exercise Price. The Holder may pay
the Exercise Price in one of the following manners:

     (a)  Cash Exercise.  The Holder shall deliver immediately available funds;
          or

     (b)  Cashless Exercise.  The Holder shall surrender this Warrant to the
Company together with a notice of cashless exercise, in which event the Company
shall issue to the Holder the number of Warrant Shares determined as follows:

                  X = Y (A-B)/A
     where:
                  X = the number of Warrant Shares to be issued to the Holder.

                  Y = the number of Warrant Shares with respect to which this
                  Warrant is being exercised.
                  A = the closing bid price of the Common Stock for the trading
                  day  immediately prior to the Date of Exercise.

                  B = the Exercise Price.

For purposes of Rule 144 promulgated under the Securities Act, it is intended,
understood and acknowledged that the Warrant Shares issued in a cashless
exercise transaction shall be deemed to have been acquired by the Holder, and
the holding period for the Warrant Shares shall be deemed to have been
commenced, on the issue date.

     (c) The Holder is limited in the amount of this Warrant it may exercise. In
no event shall the Holder be entitled to exercise any amount of this Warrant in
excess of that amount upon exercise of which the sum of (1) the number of shares
of Common Stock beneficially owned (as such term is defined under Section 13(d)
and Rule 13d-3 of the Securities Exchange Act of 1934 (the 1934 Act")) by the
Holder, and (2) the number of Warrant Shares issuable upon the exercise of any
Warrants then owned by Holder, would result in beneficial ownership by the
Holder of more than 4.99% of the outstanding shares of Common Stock of the
Company, as determined in accordance with Rule13d-1(j). Furthermore, the Company
shall not process any exercise that would result in beneficial ownership by the
Holder of more than 4.99% of the outstanding shares of Common Stock of the
Company.

     10. Fractional Shares. The Company shall not be required to issue or cause
to be issued fractional Warrant Shares on the exercise of this Warrant. The
number of full Warrant Shares which shall be issuable upon the exercise of this
Warrant shall be computed on the basis of the aggregate number of Warrant Shares
purchasable on exercise of this Warrant so presented. If any fraction of a
Warrant Share would, except for the provisions of this Section 10, be issuable
on the exercise of this Warrant, the Company shall pay an amount in cash equal
to the Exercise Price multiplied by such fraction.

     11.  Notices.  Any and all notices or other communications or deliveries
hereunder shall be in writing and shall be deemed given and effective on the
earliest of (i) the date of transmission, if such notice or communication is
delivered via facsimile at the facsimile telephone number specified in this
Section prior to 5:00 p.m. (New York City time) on a business day, (ii) the
business day after the date of transmission, if such notice or communication is
delivered via facsimile at the facsimile telephone number specified in this
Section later than 5:00 p.m. (New York City time) on any date and earlier than
11:59 p.m. (New York City time) on such date, (iii) the business day following
the date of mailing, if sent by nationally recognized overnight courier service,
or (iv) upon actual receipt by the party to whom such notice is required to be
given. The addresses for such communications shall be: (i) if to the Company,
to, Jacobson Resonance Enterprises, Inc., Attention Frank A. Chaviano, COO, 8200
Jog Road, Suite 100, Boynton Beach, Florida 33437, Telephone: 561-752-4141 or
(ii) if to the Holder, to the Holder at the address or facsimile number
appearing on the Warrant Register or such other address or facsimile number as
the Holder may provide to the Company in accordance with this Section 11.

     12.  Warrant Agent.  The Company shall serve as warrant agent under this
Warrant. Upon thirty (30) days' notice to the Holder, the Company may appoint a
new warrant agent. Any corporation into which the Company or any new warrant
agent may be merged or any corporation resulting from any consolidation to which
the Company or any new warrant agent shall be a party or any corporation to
which the Company or any new warrant agent transfers substantially all of its
corporate trust or shareholders services business shall be a successor warrant
agent under this Warrant without any further act. Any such successor warrant
agent shall promptly cause notice of its succession as warrant agent to be
mailed (by first class mail, postage prepaid) to the Holder at the Holder's last
address as shown on the Warrant Register.

     13. Miscellaneous.

        (a) This Warrant shall not be assignable.  This Warrant may be amended
only in writing signed by the Company and the Holder.

        (b)  Subject to Section 13(a), above, nothing in this Warrant shall be
construed to give to any person or corporation other than the Company and the
Holder any legal or equitable right, remedy or cause under this Warrant. This
Warrant shall inure to the sole and exclusive benefit of the Company and the
Holder.

        (c) This Warrant shall be governed by and construed and enforced in
accordance with the laws of the State of Florida without regard to the
principles of conflicts of law thereof. The Company and the Holder hereby
irrevocably submit to the exclusive jurisdiction of the state and federal courts
sitting in the State of Florida, for the adjudication of any dispute hereunder
or in connection herewith or with any transaction contemplated hereby or
discussed herein, and hereby irrevocably waives, and agrees not to assert in any
suit, action or proceeding, any claim that it is not personally subject to the
jurisdiction of any such court, or that such suit, action or proceeding is
improper. Each of the Company and the Holder hereby irrevocably waives personal
service of process and consents to process being served in any such suit, action
or proceeding by receiving a copy thereof sent to the Company at the address in
effect for notices to it under this instrument and agrees that such service
shall constitute good and sufficient service of process and notice thereof.
Nothing contained herein shall be deemed to limit in any way any right to serve
process in any manner permitted by law.

        (d) The headings herein are for convenience only, do not constitute a
part of this Warrant and shall not be deemed to limit or affect any of the
provisions hereof.

        (e) In case any one or more of the provisions of this Warrant shall be
invalid or unenforceable in any respect, the validity and enforceability of the
remaining terms and provisions of this Warrant shall not in any way be affected
or impaired thereby and the parties will attempt in good faith to agree upon a
valid and enforceable provision which shall be a commercially reasonable
substitute therefor, and upon so agreeing, shall incorporate such substitute
provision in this Warrant.

     IN WITNESS WHEREOF, the Company has caused this Warrant to be duly executed
by its authorized officer as of the date first indicated above.

                          FORM OF ELECTION TO PURCHASE

(To be executed by the Holder to exercise the right to purchase shares of Common
Stock under the foregoing Warrant)

To: Jacobson Resonance Enterprises, Inc.

     In accordance with the Warrant enclosed with this Form of Election to
