<P STYLE="margin-top:0px;margin-bottom:0px; margin-left:4%"><FONT FACE="Times New Roman" SIZE="2" COLOR="#000000">packages were mailed to home addresses. So if you think you have eligible options and you
didn&#146;t receive a package, you need to contact us quickly at 800-7-QUANTA&#151;that&#146;s 800-778-2682, and we&#146;ll mail a new package to you. </FONT></P><P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P><P
STYLE="margin-top:0px;margin-bottom:0px; margin-left:4%"><FONT FACE="Times New Roman" SIZE="2" COLOR="#000000">First, I&#146;m going to cover what this exchange offer is intended to do. As most of you know, many of the options you received have an
exercise price that is higher than the current market price of the stock. For example, if you have an option with an exercise price of $10, that&#146;s a lot higher than the current market price, which is about $3.15. Quanta management was concerned
that the options were not achieving their intended purpose, which is to incent employees. With that in mind, management recommended this stock option exchange program to the board of directors and the board approved the recommendation. </FONT></P><P
STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P><P STYLE="margin-top:0px;margin-bottom:0px; margin-left:4%"><FONT FACE="Times New Roman" SIZE="2" COLOR="#000000">By making this offer, we are hoping to provide a more
meaningful performance incentive to current employees by aligning the employee&#146;s interests with those of the shareholders and motivating employees to build shareholder value going forward. This is a completely voluntary program. You do not have
to participate in it. </FONT></P><P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P><P STYLE="margin-top:0px;margin-bottom:0px; margin-left:4%"><FONT FACE="Times New Roman" SIZE="2" COLOR="#000000">The exchange offer allows
eligible employees who choose to participate to exchange options with a exercise price of $10 or higher for shares of restricted stock. For every 2.24 option shares you exchange, you will receive one share of restricted stock. For example, if you
hold an eligible option to purchase 1,000 shares of stock and you choose to exchange this option, you&#146;ll receive 446 shares of restricted stock. </FONT></P><P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P><P
STYLE="margin-top:0px;margin-bottom:0px; margin-left:4%"><FONT FACE="Times New Roman" SIZE="2" COLOR="#000000">With that as background, now we&#146;re going to turn to some of the most frequently asked questions that we&#146;ve gotten since we
started the exchange offer. </FONT></P><P STYLE="margin-top:0px;margin-bottom:-6px"><FONT SIZE="1">&nbsp;</FONT></P><P STYLE="margin-top:0px;margin-bottom:0px; margin-left:4%"><FONT FACE="Times New Roman" SIZE="2" COLOR="#000000">The first question:
who can participate in the offer? Only individuals who are and remain employees or consultants on the date of the offer, which was January 21st, and on the exchange </FONT></P>

<HR  SIZE="3" COLOR="#999999" WIDTH="100%" ALIGN="CENTER">
<P STYLE="margin-top:0px;margin-bottom:0px; margin-left:4%"><FONT FACE="Times New Roman" SIZE="2" COLOR="#000000">date, which we expect to be February 28th, and who have not received a grant of stock
options in the six months prior to the offer date, can participate in the offer. Any option holders who are not employees or consultants on those dates, or who received a grant of stock options during the six months prior to January 21st, 2003, are
not eligible to participate in the offer. </FONT></P><P STYLE="margin-top:0px;margin-bottom:-6px"><FONT SIZE="1">&nbsp;</FONT></P><P STYLE="margin-top:0px;margin-bottom:0px; margin-left:4%"><FONT FACE="Times New Roman" SIZE="2"
COLOR="#000000">Second question: what is the difference between stock options and restricted stock? Stock options give you the right to purchase shares of our common stock at an established exercise price. Until you exercise the option and purchase
the shares, you don&#146;t actually own any stock. Unlike stock options, when you receive restricted stock, you become a holder of record of actual shares of Quanta&#146;s common stock without any need to exercise options or pay an exercise price.
However, until the shares of restricted stock vest, they remain subject to forfeiture and transfer, and other restrictions, which will be set forth in your restricted stock award. </FONT></P><P STYLE="margin-top:0px;margin-bottom:-6px"><FONT
SIZE="1">&nbsp;</FONT></P><P STYLE="margin-top:0px;margin-bottom:0px; margin-left:4%"><FONT FACE="Times New Roman" SIZE="2" COLOR="#000000">Question number three: what are the restrictions on the restricted stock? The restrictions on the restricted
stock you receive in the offer are contained in your restricted stock award. Generally, the shares of restricted stock may not be sold, transferred, assigned, pledged, or otherwise encumbered or disposed of until the shares vest. If and when your
shares of restricted stock vest, they will be released to you after you satisfy applicable withholding tax obligations. </FONT></P><P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P><P
STYLE="margin-top:0px;margin-bottom:0px; margin-left:4%"><FONT FACE="Times New Roman" SIZE="2" COLOR="#000000">When they&#146;re released to you, the shares will be unrestricted shares free and clear to sell. After the shares of restricted stock
vest, the restrictions on those vested shares are gone, those shares are yours to keep regardless of whether you remain employed by Quanta, or a Quanta subsidiary, after the vesting date. </FONT></P><P STYLE="margin-top:0px;margin-bottom:0px"><FONT
SIZE="1">&nbsp;</FONT></P><P STYLE="margin-top:0px;margin-bottom:0px; margin-left:4%"><FONT FACE="Times New Roman" SIZE="2" COLOR="#000000">When will I forfeit the restricted stock I receive in this tender offer? Generally, you&#146;ll forfeit
restricted stock if your continuous service as a Quanta employee or consultant is interrupted or terminated before the restricted stock vests. However, upon a change in control of Quanta, or if </FONT></P>

FACE="Times New Roman" SIZE="2" COLOR="#000000">Next question: isn&#146;t there a 90-day interruption of service exception to the break in continuous service? No. The 2001 stock incentive plan does not provide for a 90-day interruption of service,
although certain events, like an approved leave of absence or intercompany transfers, are determined not to constitute a break in continuous service. </FONT></P><P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P><P
