Balqon Corporation, a California corporation (the “Company”), for value
received, hereby promises to pay to ELECTRIC MOTORSPORTS, LLC or its registered
assigns (“Holder”), the sum of
One Hundred Thousand Dollars ($ 100,000) on the terms and conditions set forth
hereinafter. Payment for all amounts due hereunder shall be made by mail to the
registered address of Holder.




This Note has been issued to Holder in connection with an asset purchase
agreement (the “APA”), pursuant
to which the Company is purchasing the assets of ELECTRIC MOTORSPORTS, LLC. This
Note is the note referenced therein and is subject to the provisions of that
agreement, including, without limitation, the provisions related to holdback
rights in the APA.




The following
is a statement of the rights of Holder of this Promissory Note (the “Note”) and the
conditions to which this Note is subject, and to which Holder hereof, by the
acceptance of this Note, agrees:




1. Maturity; Partial
Prepayment. The principal hereof and any unpaid accrued interest hereon,
as set forth below, shall be due and payable on the earlier to occur of: (i) Six
Months (“Maturity
Date”); and (iii) when declared due and payable by Holder upon the
occurrence of an Event of Default (as defined below).




2. Interest. The Company
shall pay interest at the rate of the lower
of (i) the Prime Rate published in the Wall Street Journal on the date closest
to the date of this Note; or (ii) the maximum allowable rate under applicable
laws (such rate, the “Interest Rate”) on
the principal of this Note outstanding during the period beginning on the date
of this Note and ending on the date that the principal amount of this Note is
repaid in full. Interest shall be calculated on the basis of a 360-day year for
the actual number of days elapsed. Interest accruing on this Note shall be due
and payable at the Maturity Date or upon the occurrence of an Event of Default.
The Company shall pay the interest due on this Note by delivering to Holder cash
equal to the outstanding principal amount of the Note plus any due and unpaid
interest. If there occurs an acceleration or prepayment of the Note prior to the
Maturity Date in accordance with the terms hereof, all interest due and payable
at such time on the principal amount due shall be paid in full. All payments
hereunder are to be applied first to reasonable costs and fees referred to
herein, second to the payment of accrued interest, and the remaining balance to
the payment of principal.




3. Events of Default. If
any of the events specified in this Section 3 shall occur (herein individually
referred to as an “Event of Default”),
Holder may, so long as such condition exists, declare the entire principal and
unpaid accrued interest hereon immediately due and payable, by notice in writing
to the Company:




1

Default in the payment of the principal or unpaid accrued interest of this Note
when due and payable after written notice and an opportunity to cure such
breach; or




(b)
The institution by the Company of proceedings to be adjudicated as bankrupt or
insolvent, or the consent by it to institution of bankruptcy or insolvency
proceedings against it or the filing by it of a petition or answer or consent
seeking reorganization or release under the Federal Bankruptcy Act, or any other
applicable Federal or state law, or the consent by it to the filing of any such
petition or the appointment of a receiver, liquidator, assignee, trustee or
other similar official of the Company, or of any substantial part of its
property, or the making by it of an assignment for the benefit of creditors, or
the taking of corporate action by the Company in furtherance of any such action;
or




(c)
If, within sixty (60) calendar days after the commencement of an action against
the Company, without the consent or acquiescence of the Company (and service of
process in connection therewith on the Company) seeking any bankruptcy,
insolvency, reorganization, liquidation, dissolution or similar relief under any
present or future statute, law or regulation, such action shall not have been
resolved in favor of the Company or all orders or proceedings thereunder
affecting the operations or the business of the Company stayed, or if the stay
of any such order or proceeding shall thereafter be set aside, or if, within
sixty (60) calendar days after the appointment without the consent or
acquiescence of the Company of any trustee, receiver or liquidator of the
Company or of all or any substantial part of the properties of the Company, such
appointment shall not have been vacated; or

Event of Default, Holder in his sole and absolute discretion shall have the
right to declare all unpaid interest and principal immediately due and payable
and exercise all other legal rights in connection therewith.
