As a result of Michael J. Murphy's resignation from his position as Chairman of
the Office of Strategic Innovation and as a member and as Deputy Chairman of the
Board of Directors on July 25, 2006 described in Item 5.02 of this report,
Quanta Capital Holdings Ltd.'s (the "Company") and Mr. Murphy's obligations
under the Employment Agreement dated as of July 17, 2003, between the Company
and Mr. Murphy, as amended by Amendment No. 1 to Employment Agreement dated as
of March 18, 2005 (collectively, the "Employment Agreement") were terminated. On
July 25, 2006, the Company and Mr. Murphy entered into a Separation Agreement
and General Release (the "Separation and Release Agreement") which provides,
among other things, for the payment of $2,000,000 to Mr. Murphy and legal fees
of $25,000 incurred by Mr. Murphy in connection with his separation to Mr.
Murphy's attorney. The Company will make these payments to Mr. Murphy in a lump
sum, less applicable federal, state and local taxes, and other deductions,
within ten days of the Separation and Release Agreement. Additionally, if the
Company signs a letter of intent, or other document to the same effect, for a
transaction that would constitute a "change of control" (as defined in the
Employment Agreement), within 90 days of the Separation and Release Agreement,
and that transaction is thereafter consummated, then the Company must pay Mr.
Murphy the amount he is due pursuant to Section 5.03 of the Employment
Agreement, less the $2,000,000 payment described above.

In connection with the appointment of Susan Fleming Cabrera as a director of the
Company (as more fully described under Item 5.02 of this report), the
Compensation Committee of the Company granted Ms. Cabrera options to purchase
25,000 common shares at an exercise price of $2.30 per share. These options vest
in equal installments over four years and have a 10 year term.

ITEM 1.02  TERMINATION OF A MATERIAL DEFINITIVE AGREEMENT.

On July 25, 2006, in connection with entering into the Separation and Release
Agreement, the Company and Mr. Murphy terminated their respective obligations
under the Employment Agreement. The Separation and Release Agreement provides
for the payments to Mr. Murphy as described in Item 1.01 of this report.
