Item 1.01 Entry into a Material Definitive Agreement.

On April 1, 2016, Clean Diesel Technologies, Inc. (the “Company” or “CDTI”) executed a Promissory Note (the “Note”) and entered into an amendment to loan agreement (the “Agreement”) with Kanis S.A., one of the Company’s principal lenders and largest stockholders.

Pursuant to the terms of the Note, Kanis S.A. agreed to lend the Company $2,000,000 at a rate per annum equal to 8% and a maturity date of September 30, 2017. This Note shall bear no prepayment penalty.

Pursuant to the terms of the Agreement, the Company and Kanis S.A. agreed to amend certain prior loans and amendments aggregating a principal balance of $7,500,000 (collectively, the “Loan Agreements”), whereby Kanis S.A. agreed to amend the terms of the outstanding loans made to the Company, such that (i) Kanis S.A. shall have the right to convert the principal balance of the Loan Agreements and any accrued interest thereon at any time before payment by written notice exercising such optional right to convert the $7,500,000 principal balance and any accrued interest into the common stock of the Company at a conversion price equal to the lower of the closing price of CDTI on the date before the date of the Agreement or as of the date when Kanis S.A. sends written notice to the Company exercising its conversion right; and (ii) the Company shall have the right to mandatorily convert the $7,500,000 principal balance and any accrued interest into the common stock of CDTI upon the due date under the Loan Agreements or earlier upon the occurrence of a Liquidity Event at a conversion price equal to the lower of the closing price of CDTI as of the date immediately before the date of the Agreement or at a 25% discount to the Liquidity Event price. A Liquidity Event shall be defined as a strategic investment in CDTI or a public stock offering by CDTI. The Company may prepay the principal and any interest due on the Loan Agreements at any time before due date without penalty.
