     FOR VALUE RECEIVED, the receipt and sufficiency of which is hereby
acknowledged, Pinnacle Oil International, Inc., a Nevada corporation, (the
"Maker"), hereby promises to pay to George Liszicasz, or order (the "Holder"),
- ------                                                               ------   
at the address designated below on the signature page of this note, or such
other address as the Holder may from time-to-time designate by written notice to
the Maker, the principal sum described below as the "principal amount", together
with interest thereon, in the manner and at the times provided below and subject
to the terms and conditions described herein.

     (a)  PRINCIPAL AMOUNT.
          ---------------- 

          The Principal Amount shall be the amount advanced and received by
Maker as of the date hereof, or Five Hundred Thousand and No/100 Dollars
($500,000), or such principal amount as shall be outstanding from time to time
(the "Principal Amount").
      ----------------   

     2.   INTEREST.
          -------- 

          Subject to the provisions of this Section and Section 7, of this note,
interest on the Principal Amount from time-to-time remaining unpaid shall accrue
at the rate of twelve percent (12%) per annum.  Interest shall be computed on
the basis of a three hundred sixty (360) day year and a thirty (30) day month.

          Notwithstanding the foregoing, in the event the Maker and/or any
surety, guarantor or endorser of this note is in default under this note, the
described interest rate shall, subject to the terms of Section 7 of this note,
accrue from the date of such default until the balance of the Principal Amount,
accrued and unpaid interest, late charges and all other indebtedness under this
note is fully repaid, at a rate equal to the lesser of (i) the maximum legal
rate permitted at law; or (ii) the rate of fourteen percent (14%) per annum.

     3.   PAYMENT OF PRINCIPAL AND INTEREST.
          --------------------------------- 

          Subject to prior prepayment, acceleration or conversion in accordance
with the terms of this note, the Principal Amount, accrued and unpaid interest
on the Principal Amount and all other indebtedness under this note shall be due
and payable one year after the date hereof (the "Maturity Date").

                                       1

 
          Notwithstanding the foregoing, the Maker shall have the right to
prepay any portion of the Principal Amount in whole or in part (together with
any accrued and unpaid interest through the date of prepayment, plus any other
amounts due under this note), or to convert this note pursuant to Section 6,
without prepayment penalty or premium.

          Whenever any payment required under the terms of this note shall be
stated to be due on a day other than a business day, such payment shall be made
on the next succeeding business day, and such extension of time shall in such
case be included in the computation of payment of interest.

     4.   MANNER OF PAYMENTS/CREDITING OF PAYMENTS.
          ---------------------------------------- 

          Payments of any amount required hereunder shall be made solely in
lawful money of Canada, and shall be credited first against accrued but unpaid
late charges, if any, then against accrued but unpaid interest, if any, and then
against the unpaid balance of the Principal Amount.  If any payments are made by
check, such payments must be delivered to the Holder in sufficient time to allow
the funds to become same day funds on or before the due date for such payment.

     5.   NO OFFSET.
          --------- 

          The Maker shall make all payments required under this note without
offset regardless of any defense, setoff, claim, cause of action, counterclaim,
or cross-claim, whether liquidated or unliquidated, which the Maker may have or
claim to have against the Holder, whether or not related to this note
(collectively, "Claims"), and no portion of the indebtedness evidenced by this
                ------                                                        
note or any payment shall be or be deemed to be offset or compensated by all or
any part of such Claims.  The Maker waives, to the fullest extent permitted by
applicable law, the protection or benefits of any statement, code, or judicial
decision which conflicts with the terms of this Section.

6.        CONVERSION
          ----------
          
          (a) Holder's Election to Convert. The Holder may elect, at any time
              ----------------------------
prior to the Maturity Date, by provision of written notice of conversion to the
Maker delivered with surrender of this note to the Maker on or before the
Maturity Date, to convert the then outstanding principal amount of this note or
any portion thereof, plus any accrued but unpaid interest on this note, into
Common Shares of the Maker, at a conversion price of $4.07 per Common Share.

          (b) Maker's Election to Convert. If Holder has not converted the
              ---------------------------
Indebtedness prior to the earlier of the Maturity Date or the date of
Maker's listing on NASDAQ, the Maker shall, by provision of written notice
of conversion to the Holder on or before the 

                                       2

 
Maturity Date, to convert the then outstanding principal amount of this note or
any portion thereof, plus any accrued but unpaid interest on this note, into
Common Shares of the Maker, to be issued to the Holder. The number of Common
Shares to be issued to Holder shall be calculated by dividing the total
indebtedness as of such date (including any unpaid interest, late charges, costs
or expenses) by a price equal to $2.72 per Common Share.

          (c) Covenants Of Company The Maker makes the following covenants to
              --------------------
the Holder, each of which is deemed to be a separate covenant:

              (i)   Until this note is repaid or converted, the Maker shall not,
without the consent of the Holder, declare or make any dividend or other
distributions to shareholders of Maker.

              (ii)  The Maker will at all times keep true and complete books or
record and accounts in accordance with generally accepted accounting principles
and practices.

              (iii) The Maker will at all times cause to be done all things
necessary to preserve and keep in full force and effect its corporate existence,
rights and franchises; provided, however, that nothing in this Section shall
require the Company to maintain, preserve or renew any right or franchise which
in the opinion of the Board of Directors of the Company is not necessary or
desirable in the conduct of the business of the Company, in the exercise of
their reasonable business judgment.


     7.   LATE CHARGE.
          ----------- 

          If any payment of the Principal Amount and/or interest thereon (a
"Delinquent Payment") is not received by the Holder when due, a late charge the
 ------------------
("Late Charge") equal to six percent (6%) of the Delinquent Payment may be
  -----------
charged by the Holder for the purpose of defraying expenses incurred by the
Holder. In light of all of the circumstances existing on the date of this note,
the parties agree that the Late Charge represents a fair and reasonable estimate
of the costs that will be sustained by the Holder upon any failure by the Maker
to make timely payment. The parties further agree that the amount of actual
damages incurred by the Maker would be costly, inconvenient and extremely
difficult and impractical to prove. The Late Charge shall be paid without
prejudice to the Holder's right to collect any other amounts provided for under
this note, or to declare a default under this note, or from exercising any of
the other rights and remedies available to the Holder.


     8.   ACCELERATION UPON DEFAULT.
          ------------------------- 

          At the option of the Holder, all or any part of the indebtedness of
the Maker shall immediately become due and payable, irrespective of any agreed
maturity, upon the happening of 

                                       3

 
any of the following events of default (each, an "Event of Default"):
                                                  ----------------
          (a) If any part of the Principal Amount and/or interest thereon and/or
Late Charges under this note are not paid when due;

          (b) If any of the following events occurs, it shall constitute an
Event of Default under this note:


               (i)     If the Maker shall breach any non-monetary condition or

               (ii)    If the Maker shall make an assignment for the benefit of
creditors;

               (iii)   If a custodian, trustee, receiver, or agent is appointed
or takes possession of substantially all of the property of the Maker;

               (iv)    If the Maker becomes insolvent as that term is defined in
Section 101(26) of Title 11 of the United States Code;

               (v)     If the Maker shall (A) file a voluntary petition under
the Bankruptcy Code, or (B) otherwise file any petition or apply to any tribunal
for appointment of a custodian, trustee, receiver, or agent of the Maker, or
commence any proceeding related to the Maker under any bankruptcy or
reorganization statute, or under any arrangement, insolvency, readjustment of
debt, dissolution, or liquidation law of any jurisdiction, whether now or
hereafter in effect;

               (vi)    If any involuntary petition is filed against the Maker
under the Bankruptcy Code and such petition is not dismissed by the Bankruptcy
Court within thirty (30) days of the date of filing;

               (vii)   If any petition or application of the type described
above is filed against the Maker, or any proceeding of the type described above
is commenced, and either: (A) the Maker, by any act, indicates his approval
thereof, consent thereto, or acquiescence therein; or (B) an order is entered
appointing any such custodian, trustee, receiver, or agent, adjudicating the
Maker bankrupt or insolvent, or approving such petition or application in any
such proceeding, and any such order remains in effect for more than thirty (30)
days;
 
               (viii)  If any attachment, execution, or other writ is levied on
substantially all of the assets of the Maker and remains in effect for more than
fifteen (15) days; or

               (ix)    If, without the prior written consent of Holder any of

sells or hypothecates twenty-five percent (25%) or more of the Maker's gross
assets based on book value; or the Maker distributes to its shareholders twenty-
five percent (25%) or more of its gross assets based on book value.

being cured, the Maker shall be entitled to a grace period of thirty (30) days
following written notice of such event of default to cure such default, and
further provided, that if such event of default is of such character as to
- ------- --------                                                          
reasonably require more than thirty (30) days to cure, and the Maker has
promptly commenced to cure said default within the thirty (30) day period and
uses reasonable diligence thereafter in curing such default, then the thirty
(30) day period shall be reasonably extended.
