<DIV align="left" style="font-size: 10pt; margin-top: 6pt">corporation may indemnify any person who was or is a party or is threatened to be made a party to
any threatened, pending or completed action, suitor proceeding, whether civil, criminal,
administrative or investigative (other than an action by or in the right of the corporation) by
reason of the fact that such person is or was a director, officer, employee or agent of the
corporation or is or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation or enterprise, against expenses, judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in connection with such
action, suit or proceeding if he or she acted in good faith and in a manner he or she reasonably
believed to be in or not opposed to the best interests of the corporation, and, with respect to
any criminal action or proceeding, had no cause to believe his or her conduct was unlawful.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;145(b) of the DGCL provides that a Delaware corporation may indemnify any person who
was or is a party or is threatened to be made a party to any threatened, pending or completed
action or suit by or in the right of the corporation to procure a judgment in its favor by reason
of the fact that such person acted in any of the capacities set forth above, against expenses
actually and reasonably incurred by such person in connection with the defense or settlement of
such action or suit if he or she acted under similar standards to those set forth above, except
that no indemnification may be made with respect to any claim, issue or matter as to which such
person shall have been adjudged to be liable to the corporation unless and only to the extent that
the court in which such action or suit was brought shall determine that despite the adjudication of
liability, but in view of all the circumstances of the case, such person is fairly and reasonably
entitled to be indemnified for such expenses which the court shall deem proper.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;145 of the DGCL further provides that, to the extent a director or officer of a
corporation has been successful in the defense of any action, suit or proceeding referred to in
subsection (a)&nbsp;and (b)&nbsp;or in the defense of any claim, issue or matter therein, he shall be
indemnified against expenses actually and reasonably inclined by him in connection therewith; that
indemnification provided for by Section&nbsp;145 of the DGCL shall not be deemed exclusive of any other
rights to which the indemnified party may be entitled; and that the corporation may purchase and
maintain insurance on behalf of a director or officer of the corporation against any liability
asserted against such officer or director and incurred by him or her in any such capacity or
arising out of his or her status as such, whether or not the corporation would have the power to
indemnify him or her against such liabilities under Section&nbsp;145 of the DGCL.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Article&nbsp;Tenth of the registrant&#146;s Restated Certificate of Incorporation and Article&nbsp;Seven of
the registrant&#146;s Amended and Restated Bylaws contain provisions for indemnification of directors
and officers and for the advancements of expenses to any director or officer to the fullest extent
permitted by Delaware law. Additionally, Article&nbsp;Eleventh of the registrant&#146;s Restated Certificate
of Incorporation provides that no director shall be liable to the registrant or its stockholders
for monetary damages for breach of fiduciary duty as a director to the fullest extent permitted by
Delaware law.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Article&nbsp;Seven of the registrant&#146;s Amended and Restated Bylaws permits the registrant to
purchase insurance for directors and officers against liability for expenses, judgments or
settlements, whether or not the registrant would have the power to indemnify such persons against
such liabilities. The registrant has director and officer insurance in place for its directors
and officers.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In addition, the registrant has entered into Indemnity Agreements with its directors and
executive officers. The form of Indemnity Agreement entered into with each director and officer
was previously filed with the SEC as Exhibit&nbsp;10.1 to the registrant&#146;s Current Report on Form 8-K
filed on May&nbsp;31, 2005. The registrant&#146;s board of directors may from time to time authorize Quanta
to enter into additional indemnity agreements with other of its future directors and officers
utilizing the same form of Indemnity Agreement.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Indemnity Agreements generally provide that the registrant will, to the extent permitted
by applicable law, indemnify and hold harmless each indemnitee that is, or is threatened to be
made, a party to any civil, criminal or administrative proceeding against all expenses, judgments,
fines, penalties and amounts paid in settlement actually and reasonably incurred by the indemnitee
in connection with any such proceeding. The Indemnity Agreements provide the indemnitee with
indemnification rights in connection with third-party proceedings and proceedings brought by or in
the right of the registrant. In addition, the Indemnity Agreements provide for the advancement of
expenses incurred by the indemnitee in connection with any covered proceeding to the fullest
extent permitted by applicable law. The Indemnity Agreements also provide that if the
indemnification rights provided for therein are unavailable for any reason, the registrant will
pay, in the first

registered) and any deviation from the low or high end of the estimated maximum range may be
reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the

registrant has been advised that in the opinion of the SEC such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by the registrant of
expenses incurred or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final adjudication of such
issue.

any criminal action or proceeding, had no cause to believe his or her conduct was unlawful.
Section 145(b) of the DGCL provides that a Delaware corporation may indemnify any person who
was or is a party or is threatened to be made a party to any threatened, pending or completed
action or suit by or in the right of the corporation to procure a judgment in its favor by reason
of the fact that such person acted in any of the capacities set forth above, against expenses
actually and reasonably incurred by such person in connection with the defense or settlement of
such action or suit if he or she acted under similar standards to those set forth above, except
that no indemnification may be made with respect to any claim, issue or matter as to which such
person shall have been adjudged to be liable to the corporation unless and only to the extent that
the court in which such action or suit was brought shall determine that despite the adjudication of
liability, but in view of all the circumstances of the case, such person is fairly and reasonably
entitled to be indemnified for such expenses which the court shall deem proper.
Section 145 of the DGCL further provides that, to the extent a director or officer of a
corporation has been successful in the defense of any action, suit or proceeding referred to in
subsection (a) and (b) or in the defense of any claim, issue or matter therein, he shall be
indemnified against expenses actually and reasonably inclined by him in connection therewith; that
indemnification provided for by Section 145 of the DGCL shall not be deemed exclusive of any other
rights to which the indemnified party may be entitled; and that the corporation may purchase and
maintain insurance on behalf of a director or officer of the corporation against any liability
asserted against such officer or director and incurred by him or her in any such capacity or
arising out of his or her status as such, whether or not the corporation would have the power to
indemnify him or her against such liabilities under Section 145 of the DGCL.
Article Tenth of the registrant's Restated Certificate of Incorporation and Article Seven of
the registrant's Amended and Restated Bylaws contain provisions for indemnification of directors
and officers and for the advancements of expenses to any director or officer to the fullest extent
permitted by Delaware law. Additionally, Article Eleventh of the registrant's Restated Certificate
of Incorporation provides that no director shall be liable to the registrant or its stockholders
for monetary damages for breach of fiduciary duty as a director to the fullest extent permitted by
Delaware law.
Article Seven of the registrant's Amended and Restated Bylaws permits the registrant to
purchase insurance for directors and officers against liability for expenses, judgments or
settlements, whether or not the registrant would have the power to indemnify such persons against
such liabilities. The registrant has director and officer insurance in place for its directors
and officers.
In addition, the registrant has entered into Indemnity Agreements with its directors and
executive officers. The form of Indemnity Agreement entered into with each director and officer
was previously filed with the SEC as Exhibit 10.1 to the registrant's Current Report on Form 8-K
filed on May 31, 2005. The registrant's board of directors may from time to time authorize Quanta
to enter into additional indemnity agreements with other of its future directors and officers
utilizing the same form of Indemnity Agreement.
The Indemnity Agreements generally provide that the registrant will, to the extent permitted
by applicable law, indemnify and hold harmless each indemnitee that is, or is threatened to be
made, a party to any civil, criminal or administrative proceeding against all expenses, judgments,
fines, penalties and amounts paid in settlement actually and reasonably incurred by the indemnitee
in connection with any such proceeding. The Indemnity Agreements provide the indemnitee with
indemnification rights in connection with third-party proceedings and proceedings brought by or in
the right of the registrant. In addition, the Indemnity Agreements provide for the advancement of
expenses incurred by the indemnitee in connection with any covered proceeding to the fullest
extent permitted by applicable law. The Indemnity Agreements also provide that if the
indemnification rights provided for therein are unavailable for any reason, the registrant will
pay, in the first
II-3
Table of Contents
instance, the entire amount incurred by the indemnitee in connection with any covered proceeding
and waives and relinquishes any right of contribution it may have against the indemnitee.
The rights provided by the Indemnity Agreements are in addition to any other rights to
indemnification or advancement of expenses to which the indemnitee may be entitled under applicable
law, the registrant's Restated Certificate of Incorporation or Amended and Restated Bylaws, or
otherwise.
The above description of the Indemnity Agreements is subject to, and is qualified in its
entirety by reference to, all the provisions of the form of Indemnity Agreement, previously filed
as Exhibit 10.1 to the registrant's Current Report on Form 8-K filed on May 31, 2005.

Item 9. Undertakings
A. The undersigned registrant hereby undertakes: (1) to file, during any period in which
offers or sales are being made pursuant to this registration statement, a post-effective amendment
to this registration statement: (i) to include any prospectus required by Section 10(a)(3) of the
Securities Act; (ii) to reflect in the prospectus any facts or events arising after the effective
date of this registration statement (or the most recent post-effective amendment thereof) which,
individually or in aggregate, represent a fundamental change in the information set forth in this
registration statement. Notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the total dollar value of securities offered would not exceed that which is
registered) and any deviation from the low or high end of the estimated maximum range may be
reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the
aggregate, the changes in volume and price represent no more than 20 percent change in the maximum
aggregate offering price set forth in "Calculation of Registration Fee" table in the effective
registration statement; (iii) to include any material information with respect to the plan of
distribution not previously disclosed in this registration statement or any material change to such
information in this registration statement; provided, however, that paragraphs (i) and (ii) above
do not apply if the information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the registrant pursuant to Section 13 or 15(d)
of the Exchange Act that are incorporated by
II-4
Table of Contents
reference in this registration statement; (2) that, for the purpose of determining any
liability under the Securities Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering thereof; and (3) to
remove from registration by means of a post-effective amendment any of the securities being
registered which remain unsold at the termination of the offering.
B. The undersigned registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the registrant's annual report pursuant to
Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the registration statement shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such securities at that
time shall be deemed to be the initial bona fide offering thereof.
C. Insofar as indemnification for liabilities arising under the Securities Act may be
permitted to directors, officers and controlling persons of the registrant pursuant to the
provisions described under "Item 6—Indemnification of Directors and Officers", or otherwise, the
registrant has been advised that in the opinion of the SEC such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by the registrant of
expenses incurred or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final adjudication of such
issue.
