   THE COMMITTEE TO RESTORE STOCKHOLDER VALUE AND INTEGRITY FOR CLEAN DIESEL
        OUTRAGED BY CLEAN DIESEL TECHNOLOGIES' REFUSAL TO TAKE QUESTIONS

Bridgeport, CT - (October x, 2010) - The Committee to Restore Stockholder Value
and Integrity for Clean Diesel (the "Committee") is outraged by the refusal of
Clean Diesel Technologies, Inc. (the "Company") management to take more than one
question from investors or stockholders during its conference call earlier today
to discuss the Company's proposed merger with Catalytic Solutions, Inc.

While the Company on October 4, 2010, announced that the purpose of today's call
was "to review the terms of the transaction and benefits that the combination of
Clean Diesel and Catalytic Solutions will provide to our stockholders," the
Committee believes Clean Diesel failed to do so in any meaningful way.
Management had indicated the call would be limited to 50 minutes, but despite
numerous attempts by members of the Committee, who are also Clean Diesel
stockholders, to ask questions, the call was ended after less than 20 minutes
and after answering only one investor question.

The Committee believes Clean Diesel stockholders are entitled to know the
details of the planned merger with Catalytic Solutions, Inc ("CSI") well in
advance of the October 12, 2010 Annual Meeting at which they are expected to
vote on measures, such as the required reverse stock split, that would enable
the merger to occur.  To advance that belief, members of the Committee were
prepared to ask the following questions:

-    Can you please explain how the relative CDT and CSI valuations from
     Houlihan which Clean Diesel paid for were ignored by the Company, and why
     the current Board believes it best to dilute beyond those recommendations?
     And further, can you explain why the final ownership ratio for Clean Diesel
     and CSI shareholders in the new company, 36/64, was more similar to CSI's
     original bargaining position of 30/70 than to Clean Diesel's of 50/50?

-    What determination has Clean Diesel received from NASDAQ regarding a
     continued NASDAQ listing for the proposed merged company? Would you
     consummate the merger without a NASDAQ listing?

-    Can you explain why the Chairman of Clean Diesel is being paid by the
     stockholders to be Chairman, and also being paid in excess of $800,000 to
     merge with any company, much less a company which has never been profitable
     and is cash flow negative?

-    Can you please inform us how the 4 million warrants issued to the CSI
     investors and advisors can compel cash from the company, and at what price
     this can be done (this statement was buried in footnotes to the pro
     formas)?

-    Why would any Clean Diesel stockholder decide to assume a $21 million
     potential legal liability on behalf of another company when the outcome is


     uncertain and why was this contingent liability not considered a material
     adverse change upon initial disclosure to Clean Diesel in July?

-    We need help understanding the gains CSI recognized from TKK, a related
     party - how did the $5 million agreed in February 2008 become $7.5 million
     in December 2008 followed by another $3.9 million in December 2009?

-    There has been a valid demand made for a Special Meeting to replace the
     existing Board with a new Board; why has this not been announced as a
     material event on a Form 8-K and why does the Company refuse to honor the
     requests of the stockholders?

With the Annual Meeting scheduled to be held two U.S. business days from today,
Clean Diesel stockholders still do not have the answers to these and other
questions.  The Committee believes that is unacceptable and reinforces the
Committee's goal of removing the current self-serving Board of Clean Diesel and
electing the Committee's slate of independent Director nominees.  The
Committee's demands and actions on behalf of Clean Diesel stockholders are
intended to advance the best interests of stockholders.

THE COMMITTEE TO RESTORE STOCKHOLDER VALUE AND INTEGRITY FOR CLEAN DIESEL IS
PROVIDING THE FOREGOING INFORMATION TO STOCKHOLDERS PRIOR TO FILING OF A
DEFINITIVE PROXY STATEMENT PURSUANT TO RULE 14A-12.  WE ARE NOT CURRENTLY ASKING
