                        WARRANT TO PURCHASE COMMON STOCK
                                       OF
                           INTEGRAL TECHNOLOGIES, INC.

THIS CERTIFIES that Swartz Private Equity, LLC or any subsequent holder hereof
pursuant to Section 8 hereof ("Holder"), has the right to purchase from INTEGRAL
TECHNOLOGIES, INC., a Nevada corporation (the "Company"), up to 495,000 fully
paid and nonassessable shares of the Company's common stock, $.001 par value per
share ("Common Stock"), subject to adjustment as provided herein, at a price
equal to the Exercise Price as defined in Section 3 below, at any time beginning
on the Date of Issuance (defined below) and ending at 5:00 p.m., New York, New
York time the date that is five (5) years after the Date of Issuance (the

     Holder agrees with the Company that this Warrant to Purchase Common Stock
of the Company (this "Warrant") is issued and all rights hereunder shall be held
subject to all of the conditions, limitations and provisions set forth herein.

     1. Date of Issuance and Term.

This Warrant shall be deemed to be issued on December 13, 1999 ("Date of
Issuance"). The term of this Warrant is five (5) years from the Date of
Issuance.

     Of this Warrant to purchase four hundred ninety five thousand (495,000)
shares of Common Stock of the Company, the Warrant is exercisable as to one
hundred sixty-five thousand (165,000) shares of Common Stock of the Company
after the ten (10) business day document review period, as the same may be
extended by mutual consent of the Company and the Holder (the "Review Period")
referenced in the Equity Line Letter of Agreement dated on or about December 13,
1999, between Holder and Company (the "Letter of Agreement") has ended, shall be
further exercisable as to the an additional one hundred sixty-five thousand
(165,000) shares of Common Stock of the Company upon the execution of all
Closing Documents (as defined in the Letter of Agreement) and shall be further
exercisable as to the remaining one hundred sixty-five thousand (165,000) shares
of Common Stock of the Company upon the sooner of (i) the date that is six (6)
months from December 13, 1999 or (ii) the date of the effectiveness of Company's
registration statement (the "Registration Statement") to be filed pursuant to
the Closing Documents.



<PAGE>   2





Anything in this Warrant to the contrary notwithstanding, if the Company
delivers written notice to Swartz Private Equity, LLC prior to the expiration of
the Review Period that the legal documents for the transaction are unacceptable
and the Company wishes to terminate the transaction, Holder shall return this
Warrant to the Company and all of Holder's rights under this Warrant shall be
null and void and of no effect.

     2. Exercise.

     (a) Manner of Exercise. During the Exercise Period, this Warrant may be
exercised as to all or any lesser number of full shares of Common Stock covered
hereby (the "Warrant Shares") upon surrender of this Warrant, with the Exercise
Form attached hereto as Exhibit A (the "Exercise Form") duly completed and
executed, together with the full Exercise Price (as defined below) for each
share of Common Stock as to which this Warrant is exercised, at the office of
the Company, Attention: William S. Robinson, Chairman and CEO, Integral
Technologies, Inc., 1070 West Pender Street, Suite 3, Vancouver, BC V6E 2N7;
Telephone: (604) 685-9933, Facsimile: (604) 685-6794, or at such other office or
agency as the Company may designate in writing, by overnight mail, with an
advance copy of the Exercise Form sent to the Company and its Transfer Agent by
facsimile (such surrender and payment of the Exercise Price hereinafter called
the "Exercise of this Warrant").

     (b) Date of Exercise. The "Date of Exercise" of the Warrant shall be
defined as the date that the advance copy of the completed and executed Exercise
Form is sent by facsimile to the Company, provided that the original Warrant and
Exercise Form are received by the Company as soon as practicable thereafter.
Alternatively, the Date of Exercise shall be defined as the date the original
Exercise Form is received by the Company, if Holder has not sent advance notice
by facsimile.

     (c) Cancellation of Warrant. This Warrant shall be canceled upon the
Exercise of this Warrant, and, as soon as practical after the Date of Exercise,
Holder shall be entitled to receive Common Stock for the number of shares
purchased upon such Exercise of this Warrant, and if this Warrant is not
exercised in full, Holder shall be entitled to receive a new Warrant (containing
terms identical to this Warrant) representing any unexercised portion of this
Warrant in addition to such Common Stock.

     (d) Holder of Record. Each person in whose name any Warrant for shares of
Common Stock is issued shall, for all purposes, be deemed to be the Holder of
record of such shares on the Date of Exercise of this Warrant, irrespective of
the date of delivery of the Common Stock purchased upon the Exercise of this
Warrant. Nothing in this Warrant shall be construed as conferring upon Holder
any rights as a stockholder of the Company.

     3. Payment of Warrant Exercise Price.

The Exercise Price per share ("Exercise Price") shall initially equal $1.306
(the "Initial Exercise Price"). If the lowest Closing Price for the Company's
Common Stock for the five (5) trading days immediately preceding the date, if
any, that the Company and Swartz Private Equity, LLC enter into an Investment
Agreement ("Investment Agreement") pursuant to the Letter of Agreement (the
"Market Price at Closing") is less than the Initial Exercise Price, the Exercise
Price shall be reset to equal the Market Price at Closing, or, if the Date of
Exercise is more than six (6) months after the Date of Issuance, the Exercise
Price shall be reset to equal the lesser of (i) the Exercise Price then in
effect, or (ii) the "Lowest Reset Price," as that term is defined below. The
Company shall calculate a "Reset Price" on each six-month anniversary date of
the Date of


                                       2

<PAGE>   3



Issuance which shall equal one hundred percent (100%) of the lowest Closing
Price of the Company's Common Stock for the five (5) trading days ending on such
six-month anniversary date of the Date of Issuance. The "Lowest Reset Price"
shall equal the lowest Reset Price determined on any six-month anniversary date
of the Date of Issuance preceding the Date of Exercise, taking into account, as
appropriate, any adjustments made pursuant to Section 5 hereof.

Payment of the Exercise Price may be made by either of the following, or a
combination thereof, at the election of Holder:

     (i) Cash Exercise: cash, bank or cashiers check or wire transfer; or

     (ii) Cashless Exercise: The Holder, at its option, may exercise this
Warrant in a cashless exercise transaction under this subsection (ii) if and
only if, on the Date of Exercise, there is not then in effect a current
registration statement that covers the resale of the shares of Common Stock to
be issued upon exercise of this Warrant. In order to effect a Cashless Exercise,
the Holder shall surrender of this Warrant at the principal office of the
Company together with notice of cashless election, in which event the Company
shall issue 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 Holder.

       Y = the number of shares of Common Stock for which this Warrant is being
exercised.

       A = the Market Price of one (1) share of Common Stock (for purposes of
this Section 3 (ii) the "Market Price" shall be defined as the average Closing
Price of the Common Stock for the five (5) trading days prior to the Date of
Exercise of this Warrant (the "Average Closing Price"), as reported by the
O.T.C. Bulletin Board, National Association of Securities Dealers Automated
Quotation System ("Nasdaq") Small Cap Market, or if the Common Stock is not
traded on the Nasdaq Small Cap Market, the Average Closing Price in any other
over-the-counter market; provided, however, that if the Common Stock is listed
on a stock exchange, the Market Price shall be the Average Closing Price on such
exchange for the five (5) trading days prior to the date of exercise of the
Warrants. If the Common Stock is/was not traded during the five (5) trading days
prior to the Date of Exercise, then the closing price for the last publicly
traded day shall be deemed to be the closing price for any and all (if
applicable) days during such five (5) trading day period.

       B = the Exercise Price.

     For purposes hereof, the term "Closing Price" shall mean the closing price
on the the Nasdaq Small Cap Market, the National Market System ("NMS" ), the New
York Stock Exchange, or the O.T.C. Bulletin Board, or if no longer traded on the
Nasdaq Small Cap Market, the National Market System ("NMS"), the New York Stock
Exchange, or the O.T.C. Bulletin Board, the "Closing Price" shall equal the
closing price on the principal national securities exchange or the
over-the-counter system on which the Common Stock is so traded and, if not
available, the mean of the high and low prices on the principal national
securities exchange on which the Common Stock is so traded.

     For purposes of Rule 144 and sub-section (d)(3)(ii) thereof, it is
intended, understood and acknowledged that the Common Stock issuable upon
exercise of this Warrant in a cashless exercise transaction shall be deemed to
have been acquired at the time this Warrant was issued. Moreover, it is
intended, understood and acknowledged that the holding period for the Common
Stock issuable upon exercise of this Warrant in a cashless exercise transaction
shall be deemed to have commenced on the date this Warrant was issued.

     4. Transfer and Registration.

     (a) Transfer Rights. Subject to the provisions of Section 8 of this
Warrant, this Warrant may be transferred on the books of the Company, in whole
or in part, in person or by attorney, upon surrender of this Warrant properly
completed and endorsed. This Warrant shall be canceled upon such surrender and,
as soon as practicable thereafter, the person to whom such transfer is made
shall be entitled to receive a new Warrant or Warrants as to the portion of this
Warrant transferred, and Holder shall be entitled to receive a new Warrant as to
the portion hereof retained.

     (b) Registrable Securities. In addition to any other registration rights of
the Holder, if the Common Stock issuable upon exercise of this Warrant is not
registered for resale at the time the Company proposes to register (including
for this purpose a registration effected by the Company for stockholders other
than the Holders) any of its Common Stock under the Act (other than a
registration relating solely for the sale of securities to participants in a
Company stock plan or a registration on Form S-4 promulgated under the Act or
any successor or similar form registering stock issuable upon a
reclassification, upon a business combination involving an exchange of
securities or upon an exchange offer for securities of the issuer or another
entity)

     (a "Piggyback Registration Statement"), the Company shall cause to be
included in such Piggyback Registration Statement ("Piggyback Registration") all
of the Common Stock issuable upon the exercise of this Warrant ("Registrable
Securities") to the extent such inclusion does not violate the registration
rights of any other securityholder of the Company granted prior to the date
hereof. Nothing herein shall prevent the Company from withdrawing or abandoning
the Piggyback Registration Statement prior to its effectiveness.

     (c) Limitation on Obligations to Register under a Piggyback Registration.
In the case of a Piggyback Registration pursuant to an underwritten public
offering by the Company, if the managing underwriter determines and advises in
writing that the inclusion in the registration statement of all Registrable
Securities proposed to be included would interfere with the successful marketing
of the securities proposed to be registered by the Company, then the number of
such Registrable Securities to be included in the Piggyback Registration
Statement, to the extent such Registrable Securities may be included in such
Piggyback Registration Statement, shall be allocated among all Holders who had
requested Piggyback Registration pursuant to the terms hereof, in the proportion
that the number of Registrable Securities which each such Holder seeks to
register bears to the total number of Registrable Securities sought to be
included by all Holders. If required by the managing underwriter of such an
underwritten public offering, the Holders shall enter into a reasonable
agreement limiting the number of Registrable Securities to be included in such
Piggyback Registration Statement and the terms, if any, regarding the future
sale of such Registrable Securities.

     5. Anti-Dilution Adjustments.

     (a) Stock Dividend. If the Company shall at any time declare a dividend
payable in shares of Common Stock, then Holder, upon Exercise of this Warrant
after the record date for the determination of holders of Common Stock entitled
to receive such dividend, shall be entitled to receive upon Exercise of this
Warrant, in addition to the number of shares of Common Stock as to which this
Warrant is exercised, such additional shares of Common Stock as such Holder
would have received had this Warrant been exercised immediately prior to such
record date and the Exercise Price will be proportionately adjusted.

     (b) Recapitalization or Reclassification.

         (i) Stock Split. If the Company shall at any time effect a
recapitalization, reclassification or other similar transaction of such
character that the shares of Common Stock shall be changed into or become
exchangeable for a larger number of shares (a "Stock Split"), then upon the
effective date thereof, the number of shares of Common Stock which Holder shall
be entitled to purchase upon Exercise of this Warrant shall be increased in
direct proportion to the increase in the number of shares of Common Stock by
reason of such recapitalization, reclassification or similar transaction, and
the Exercise Price shall be proportionally decreased.

         (ii) Reverse Stock Split. If the Company shall at any time effect a
recapitalization, reclassification or other similar transaction of such
character that the shares of Common Stock shall be changed into or become
exchangeable for a smaller number of shares (a "Reverse Stock Split"), then upon
the effective date thereof, the number of shares of Common Stock which Holder
shall be entitled to purchase upon Exercise of this Warrant shall be
proportionately decreased and the Exercise Price shall be proportionally
increased. The Company shall give Holder the same notice it provides to holders
of Common Stock of any transaction described in this Section 5(b).

     (c) Distributions. If the Company shall at any time distribute for no
consideration to holders of Common Stock cash, evidences of indebtedness or
other securities or assets (other than cash dividends or distributions payable
out of earned surplus or net profits for the current or preceding years) then,
in any such case, Holder shall be entitled to receive, upon Exercise of this
Warrant, with respect to each share of Common Stock issuable upon such exercise,
the amount of cash or evidences of indebtedness or other securities or assets
which Holder would have been entitled to receive with respect to each such share
of Common Stock as a result of the happening of such event had this Warrant been
exercised immediately prior to the record date or other date fixing shareholders
to be affected by such event (the "Determination Date") or, in lieu thereof, if
the Board of Directors of the Company should so determine at the time of such
distribution, a reduced Exercise Price determined by multiplying the Exercise
Price on the Determination Date by a fraction, the numerator of which is the
result of such Exercise Price reduced by the value of such distribution
applicable to one share of Common Stock (such value to be determined by the
Board of Directors of the Company in its discretion) and the denominator of
which is such Exercise Price.

     (d) Notice of Consolidation or Merger. In the event of a merger,
consolidation, exchange of shares, recapitalization, reorganization, or other
similar event, as a result of which shares of Common Stock shall be changed into
the same or a different number of shares of the same or another class or classes
of stock or securities or other assets of the Company or another entity or there
is a sale of all or substantially all the Company's assets (a "Corporate
Change"), then this Warrant shall be exercisable into such class and type of
securities or other assets as Holder would have received had



                                       5

<PAGE>   6



Holder exercised this Warrant immediately prior to such Corporate Change;
provided, however, that Company may not affect any Corporate Change unless it
first shall have given thirty (30) days notice to Holder hereof of any Corporate
Change.

     (e) Exercise Price Adjusted. As used in this Warrant, the term "Exercise
Price" shall mean the purchase puce per share specified in Section 3 of this
Warrant, until the occurrence of an event stated in subsection (a), (b) or (c)
of this Section 5, and thereafter shall mean said price as adjusted from time to
time in accordance with the provisions of said subsection. No such adjustment
under this Section 5 shall be made unless such adjustment would change the
Exercise Price at the time by $.O1 or more; provided, however, that all
adjustments not so made shall be deferred and made when the aggregate thereof
would change the Exercise Price at the time by $.O1 or more.

     (f)  Adjustments: Additional Shares, Securities or Assets. In the event
          that at any time, as a result of an adjustment made pursuant to this
          Section 5, Holder shall, upon Exercise of this Warrant, become
          entitled to receive shares and/or other securities or assets (other
          than Common Stock) then, wherever appropriate, all references herein
          to shares of Common Stock shall be deemed to refer to and include such
          shares and/or other securities or assets; and thereafter the number of
          such shares and/or other securities or assets shall be subject to
          adjustment from time to time in a manner and upon terms as nearly
          equivalent as practicable to the provisions of this Section 5.

     6. Fractional Interests.

         No fractional shares or scrip representing fractional shares shall be
issuable upon the Exercise of this Warrant, but on Exercise of this Warrant,
Holder may purchase only a whole number of shares of Common Stock. If, on
Exercise of this Warrant, Holder would be entitled to a fractional share of
Common Stock or a right to acquire a fractional share of Common Stock, such
fractional share shall be disregarded and the number of shares of Common Stock
issuable upon exercise shall be the next higher number of shares.

     7. Reservation of Shares.

         The Company shall at all times reserve for issuance such number of
authorized and unissued shares of Common Stock (or other securities substituted
therefor as herein above provided) as shall be sufficient for the Exercise of
this Warrant and payment of the Exercise Price. The Company covenants and agrees
that upon the Exercise of this Warrant, all shares of Common Stock issuable upon
such exercise shall be duly and validly issued, fully paid, nonassessable and
not subject to preemptive rights, rights of first refusal or similar rights of
any person or entity.

     8. Restrictions on Transfer.

     (a) Registration or Exemption Required. This Warrant has been issued in a
transaction exempt from the registration requirements of the Act by virtue of
Regulation D and exempt from state registration under applicable state laws. The
Warrant and the Common Stock issuable upon the Exercise of this Warrant may not
be pledged, transferred, sold or assigned except pursuant to an effective
registration statement or unless the Company has received an opinion from the
Company's counsel to the effect that such registration is not required, or the
Holder has furnished to the Company an opinion of the Holder's counsel, which
counsel shall be reasonably satisfactory to the Company, to the effect that such
registration is not required; the transfer complies with any applicable state
securities laws; and, if no registration covering the resale of the Warrant
Shares is effective at the time the Warrant Shares are issued, the Holder
consents


                                       6


<PAGE>   7



to a legend being placed on certificates for the Warrant Shares stating that the
securities have not been registered under the Securities Act and referring to
such restrictions on transferability and sale.

     (b) Assignment. If Holder can provide the Company with reasonably
satisfactory evidence that the conditions of (a) above regarding registration or
exemption have been satisfied, Holder may sell, transfer, assign, pledge or
otherwise dispose of this Warrant, in whole or in part. Holder shall deliver a
written notice to Company, substantially in the form of the Assignment attached
hereto as Exhibit B, indicating the person or persons to whom the Warrant shall
be assigned and the respective number of warrants to be assigned to each
assignee. The Company shall effect the assignment within ten (10) days, and
shall deliver to the assignee(s) designated by Holder a Warrant or Warrants of
like tenor and terms for the appropriate number of shares.

     9. Benefits of this Warrant.

         Nothing in this Warrant shall be construed to confer upon any person
other than the Company and Holder any legal or equitable right, remedy or claim
under this Warrant and this Warrant shall be for the sole and exclusive benefit
of the Company and Holder.

     10. Applicable Law.

         This Warrant is issued under and shall for all purposes be governed by
and construed in accordance with the laws of the state of Nevada, without giving
effect to conflict of law provisions thereof.

     11. Loss of Warrant.

         Upon receipt by the Company of evidence of the loss, theft, destruction
or mutilation of this Warrant, and (in the case of loss, theft or destruction)
of indemnity or security reasonably satisfactory to the Company, and upon
surrender and cancellation of this Warrant, if mutilated, the Company shall
execute and deliver a new Warrant of like tenor and date.

     12. Notice or Demands.

Notices or demands pursuant to this Warrant to be given or made by Holder to or
on the Company shall be sufficiently given or made if sent by certified or
registered mail, return receipt requested, postage prepaid, and addressed, until
