MINIMUM ADVERTISED PRICING POLICY

High Flow Fuel Systems, Inc., a California corporation, d/b/a Quantum Fuel Systems
(“Company”), has unilaterally adopted a minimum advertised price policy (the “Policy”) for all
of its products. The Company has determined that the Policy will protect the ability of
Company’s dealers, distributors and other re-sellers to compete competitively in the marketplace,
as well as protect the value and distinction of Company’s exceptional products and technology,
and the Company’s brand and reputation. The Policy is as follows:

1. Company has established a minimum advertised price (“MAP”) for all Company
products. The MAP for all Company products shall be listed on each Company price sheet for
distributors, dealers and re-sellers. MAP pricing is established by the Company for all Company
products and may be adjusted by Company at its sole discretion with or without notice.

2. It is a violation of this Policy if advertising of the product(s): (i) fails to display a
price equal to or greater than the MAP for the product as specified on the current Company price
list; or (ii) contains a price lower than the MAP set forth in the current Company price list. If
Company determines that a dealer, distributor or other re-seller has violated the Policy, Company
will attempt to notify the offending party (and any distributor who sells to the offending party) of
the violation and provide it with a timeframe in which the advertising must be brought into
compliance. If the offending party does not correct the violation within the time period
established by Company, Company may cease supplying the product(s) in question to the
offending party (and any distributor who sells to the offending party). Furthermore, use of
Company’s name, trademarks, logos, images, intellectual property, endorsements, marketing
materials and other documentation and information is conditioned on compliance with this
Policy.

3. This Policy applies to all forms of dealer advertising including mailings, catalogs,
displays at consumer exhibitions and shows, emails or other electronic messages to customers or
potential customers (except in direct response to a customer inquiry), and any and all other forms
of advertising media, including, without limitation, the Internet and any other electronic network.
Any price information relating to the Company’s products on an Internet website which can be
accessed directly through any hypertext link or by any other method which uses the hypertext
transfer protocol (http) is considered to be advertising for purposes of this Policy and must not
indicate that a price lower than the MAP is available at final checkout. Electronic mail sent in
direct response to a customer inquiry is not considered to be advertising.

4. This Policy only concerns advertised prices, and does not relate to actual sales
prices of any item. Further, this Policy applies equally to all Company distributors, dealers and
other re-sellers. It is the responsibility of each dealer, distributor and other re-seller to monitor
Company’s current price list for any changes and review all advertising before publication to
ensure compliance with the Policy. Violations of the Policy should be reported to Company via
email to operations@highflowfuel.com.

5. The foregoing is a statement of the Company’s unilateral policy and expresses the
terms upon which the Company will deal with its customers. This Policy may be modified by the
Company from time-to-time with or without notice. Company’s sales and customer service
personnel do not have the authority to modify or grant exceptions to the Policy. The Company
does not seek, nor will it accept, any agreement or understanding with respect to the prices that
Company distributors, dealers and re-sellers may advertise or charge at any time.

PLEASE REVIEW THIS POLICY CAREFULLY AND COMMUNICATE IT TO ALL
INDIVIDUALS WITHIN YOUR ORGANIZATION, AND IF APPLICABLE, TO ANY
DEALERS AND OTHER RE-SELLERS TO WHOM YOU DISTRIBUTE PRODUCTS.
IT GOVERNS CERTAIN CONDITIONS OF SALE FOR FUTURE ORDERS.
