ITEM 1.02(e) TERMINATION OF MATERIAL DEFINITIVE AGREEMENT.

On August 22, 2007, Quanta Capital Holdings Ltd. (the "Company") purchased all
of the outstanding floating rate capital securities (the "Trust Preferred
Securities") of (i) Quanta Capital Statutory Trust I, an affiliated Delaware
trust formed on December 21, 2004 (the "Trust I"), and (ii) Quanta Capital
Statutory Trust II, an affiliated Delaware trust formed on February 22, 2005
(the "Trust II" and together with Trust I, the "Trusts"), for an aggregate
purchase price of $54,454,666.67. The Company originally issued and sold
$60,000,000.00 of the Trust Preferred Securities in private placements.

The terms of the Trust Preferred Securities issued by Trust I and Trust II are
governed, respectively, by (i) an Amended and Restated Declaration of Trust
dated December 21, 2004 (the "Declaration I"), by and among the Company, as
sponsor, HSBC Bank USA, National Association, as a successor to Chase Manhattan
Bank USA, National Association, as institutional trustee (the "Institutional
Trustee"), HSBC Bank USA, National Association, as a successor to JPMorgan Chase
Bank, N.A., as Delaware trustee (the "Delaware Trustee"), trust administrators
named therein and the holders from time to time of beneficial interests in the
assets of the Trust I and (ii) an Amended and Restated Declaration of Trust
dated February 24, 2005 (the "Declaration II" and together with the Declaration
I, the "Declarations"), by and among the Company, as sponsor, the Institutional
Trustee, the Delaware Trustee, trust administrators named therein and the
holders from time to time of beneficial interests in the assets of the Trust II.
The Company agreed to guarantee the payment of, distributions and payments on,
liquidation or redemption of the Trust Preferred Securities, in each case to the
extent of funds held by the Trusts, pursuant to the Guarantee Agreements, dated
December 21, 2004 and February 24, 2005 (the "Guarantees"), each by and between
the Company and HSBC Bank USA, National Association, as a successor to JPMorgan
Chase Bank, N.A., as trustee (the "Trustee").

Trust I and Trust II used the proceeds from the sale of the Trust Preferred
Securities to purchase, respectively, (i) junior subordinated debt securities,
due March 15, 2035, in the principal amount of $40,000,000.00, issued by the
Company (the "Debentures I"), pursuant to an Indenture dated December 21, 2004
(the "Indenture I"), by and between the Company and the Trustee, and (ii) junior
subordinated debt securities, due June 15, 2035, in the principal amount of
$20,000,000.00, issued by the Company (the "Debentures II" and together with the
Debentures I, the "Debentures"), pursuant to an Indenture dated February 24,
2005 (the "Indenture II" and together with the Indenture I, the "Indentures"),
by and between the Company and the Trustee.

Following the purchase of the Trust Preferred Securities, the Company intends to
cancel the Trust Preferred Securities, dissolve the Trusts and terminate the
Declarations, the Guarantees, the Debentures and the Indentures.
