Directors or Certain Officers; Election of Directors; Appointment of Certain

<P style="font-size: 10pt" align="left"><U>Discretionary Cash Bonus Awards</U>

<P style="font-size: 10pt" align="left">On September&nbsp;8, 2011, the Board
of Directors of Clean Diesel Technologies, Inc. (the &#147;Company&#148;)
approved upon recommendation of the Compensation
and Nominating Committee (the &#8220;Compensation Committee&#8221;)
the issuance of discretionary cash bonus awards to certain executive
officers, as well as other key employees, in recognition of their ongoing
contributions to the Company.

<P style="font-size: 10pt" align="left">In its deliberations concerning the
award of these bonuses, the Compensation Committee took into consideration the
fact that no cash payouts were made in early 2011 under any discretionary
incentive plans that employees were eligible for at such time due to the
Company&#8217;s financial condition at that time. The Compensation Committee
also considered that Catalytic Solutions, Inc. (&#8220;CSI&#8221;) similarly
did not pay any cash bonuses to its employees (who are now employees of the
Company) under the incentive plans for which such employees were eligible for
the period prior to the Company&#8217;s business combination with CSI.

<P style="font-size: 10pt" align="left">Charles F. Call, the Company&#8217;s
Chief Executive Officer (its principal executive officer and a named executive
officer), was awarded a discretionary cash bonus in the amount of $77,733.63.
Nikhil A. Mehta, the Company&#8217;s Chief Financial Officer and Treasurer (its
principal financial officer) was awarded a discretionary cash bonus in the
amount of $39,179.30.

<P style="font-size: 10pt" align="justify"><U>Restricted Share Unit Grant</U>

<P style="font-size: 10pt" align="justify">On September&nbsp;8, 2011, the Board
of Directors approved upon recommendation of the Compensation Committee the
grant of a restricted share unit (RSU)&nbsp;award under the Clean Diesel
Technologies, Inc. 1994 Incentive Plan, as amended (the &#8220;Plan&#8221;), to
Nikhil A. Mehta, Chief Financial Officer and Treasurer of the Company, in light
of his extra efforts in the Company&#8217;s July&nbsp;2011 public offering.

<P style="font-size: 10pt" align="justify">Pursuant to a Restricted Share Unit
Agreement entered into by and between the Company and Mr.&nbsp;Mehta, the award
of 13,334 shares will vest in full six (6)&nbsp;business days from the grant
date. Issuance of the shares of Company common stock underlying the RSU is
expected to occur on the vesting date. RSUs that have not vested at the time of
the grantee&#8217;s termination of service, for any or no reason, will be
forfeited.

<P style="font-size: 10pt" align="justify">The foregoing summary of the RSU
award does not purport to be complete and is qualified in its entirety by
reference to the form of Restricted Share Unit Agreement attached as
Exhibit&nbsp;10.1 to this Current Report on Form 8-K as well as to the Clean
Diesel Technologies, Inc. 1994 Incentive Plan, as amended, which is filed as
Exhibit&nbsp;10.2 to this Current Report on Form&nbsp;8-K.
