This Executive Order is based on emission testing XL Hybrids, Inc. conducted with the
XL3 Hybrid System. The Air Resources Board reserves the right to conduct additional
emission tests in the future. If such test results demonstrate that the XL3 Hybrid
System adversely affects emissions, this Executive Order may be rescinded. Further, if
such test results or other evidence provides the Air Resources Board with reasons to
suspect that the XL3 Hybrid System will affect the durability of the emission control
system, XL Hybrids, Inc. shall be required to submit durability data to show that the
durability of the vehicle emission control system is not, in fact, affected and/or that the
add—on or modified parts demonstrate adequate durability.

XL Hybrids Inc. shall collect On—Board Diagnostic II (OBDII) mode $09 data upon
installation of the Hybrid System and again after approximately 6 months of customer
use for at least 5 vehicles from the 2016 model year to be provided within one year of
the first date of sale of the Hybrid System. If the mode $09 data demonstrate that the
XL3 Hybrid System does not comply with the minimum in—use monitor performance
rates specified in 13 CCR 1968.2, this Executive Order may be rescinded.

This Executive Order is valid provided that installation instructions for the XL3 Hybrid
System do not recommend tuning the vehicles to specifications different from those of
the vehicle manufacturer.

Changes made to the design or operating conditions of the XL3 Hybrid System, as
exempt by the Air Resources Board, which adversely affect the performance of the
vehicle‘s emission control system, shall invalidate this Executive Order.

Marketing of the XL3 Hybrid System using identification other than that shown in this
Executive Order or for an application other than that listed in this Executive Order shall
be prohibited unless prior approval is obtained from the Air Resources Board.

Exemption of the XL3 Hybrid System shall not be construed as exemption to sell, offer
for sale, or advertise any component of the system as an individual device.

This Executive Order shall not apply to any XL3 Hybrid System advertised, or offered
for sale, sold with, or installed on a motor vehicle prior to or concurrent with transfer to
an ultimate purchaser.

Order. The Executive Order may be revoked only after a ten—day written notice of
intention to revoke the Executive Order, in which period the holder of the Executive
Order may request in writing a hearing to contest the proposed revocation. If a hearing
is requested, it shall be held within ten days of receipt of the request, and the Executive
