<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Change of Control Agreements provide each executive party thereto with specified severance
payments if the executive&#146;s employment is terminated following a change of control of Quanta. These
agreements are supplemental to other employments agreements that generally govern the employment
relationship between Quanta and its executives.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;At a meeting held on December&nbsp;2, 2004, the Board of Directors of Quanta determined that it
would be in the best interests of the shareholders of Quanta to terminate the Change of Control
Agreements. On December&nbsp;9, 2004, Quanta delivered notice of termination of the Change of Control
Agreements to each of the executive parties thereto. The Change of Control Agreements provide
that, on each anniversary of the execution date thereof, they shall be renewed for an additional
three-year term unless Quanta provides notice to the executive, within 60&nbsp;days prior to the
anniversary date, that the term of the agreement will not be so extended. Accordingly, as a result
of the termination notices, the Change of Control Agreements will terminate on March&nbsp;13, 2007.
