<p class=MsoNormal><b>Item 6.</b><b>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
Indemnification of Directors and Officers.</b></p>



<p class=MsoNormal style='text-autospace:none'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
PDC's <b>bylaws</b> contain provisions providing that
PDC shall indemnify any person who was or is a party or threatened to be made a
party to any threatened, pending or completed action or proceeding, whether
civil, criminal, administrative or investigative, by reason of the fact that he
or she is or was a director, officer, employee or other agent of PDC, or is or
was serving at the request of PDC as a director, officer, employee, or other
agent of another corporation, partnership, joint venture, trust, or other
enterprise, against expenses, judgments, fines, settlements and other amounts
actually and reasonably incurred in connection with that proceeding, if that
person acted in good faith and in a manner that person reasonably believed to
be in the best interests of PDC, and in actions by PDC with such care,
including reasonable inquiry, as an ordinarily prudent person in a like
position would use under similar circumstances, and, in the case of a criminal
proceeding, had no reasonable cause to believe the conduct of that person was
unlawful.</p>



<p class=MsoNormal style='text-autospace:none'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
To the extent that any director, officer, employee or other agent of PDC has
been successful on the merits in defense of any proceeding referred to in the
bylaws, that person shall be indemnified against expenses actually and
reasonably incurred by that person in connection with that proceeding.&nbsp;
Except as provided in the preceding sentence, any indemnification may be made
by PDC only if authorized in the specific case upon a determination that
indemnification of the director, officer, employee or other agent is proper in
the circumstances because that person has met the applicable standard of
conduct set forth in the bylaws by (a) a majority vote of a quorum consisting
of directors who are not parties to the proceeding; (b) approval by the
affirmative vote of a majority of the shares of PDC represented and voting at a
duly held meeting at which a quorum is present (which shares voting
affirmatively also constitute at least a majority of the required quorum); or
(c) the court in which the proceeding is or was pending, upon application made
by PDC or the subject person or the attorney or other person rendering the
services in connection with the defense, whether or not the application by the
subject person, attorney or other person is opposed by PDC.</p>



<p class=MsoNormal style='text-autospace:none'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
Expenses incurred in defending any proceeding may be advanced by PDC before the
final disposition of the proceeding upon receipt of an undertaking by or on
behalf of the director, officer, employee or other agent of PDC to repay the
amount of the advance unless it shall be determined ultimately that the subject
person is entitled to be indemnified as authorized by the bylaws.</p>



<p class=MsoNormal style='text-autospace:none'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
PDC's <b>Articles of Incorporation</b> provide that
no director or officer of PDC shall be personally liable to PDC or its
stockholders for monetary damages for breach of fiduciary duty as a director or
officer, except for liability for (i) an act or
omission that involves intentional misconduct, fraud or a knowing violation of
the law; (ii) an act or omission for which the liability of a director or
officer is expressly provided for by an applicable statute, including the
liability for payment of distributions in violation of Section 78.300 of the
Nevada Revised Statues; and (iii) any other act, omission, transaction or
breach of duty as to which any applicable statute, rule or regulation provides
that the liability of directors or officers may not be eliminated or limited.</p>

</b>Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling

the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable.&nbsp; 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 Act and
will be governed by the final adjudication of such issue.</p>

Exchange Act of 1934, as amended, prior to the filing of a post-effective

documents to be incorporated by reference into this Registration Statement and to
be part of this Registration Statement from the dates of filing such
documents.  Copies of these documents will not be filed with this
Registration Statement.  Any statement contained herein or in a document
incorporated or deemed to be incorporated by reference herein shall be deemed
to be modified or superseded for purposes of this Registration Statement to the
extent that such statement is modified or superseded by a subsequently filed

Registration Statement.  Any such statement so modified or superseded
shall not be deemed to constitute a part of this Registration Statement except
as so modified or superseded.

Item 6.
Indemnification of Directors and Officers.
PDC's
bylaws
contain provisions providing that
PDC shall indemnify any person who was or is a party or threatened to be made a
party to any threatened, pending or completed action or proceeding, whether
civil, criminal, administrative or investigative, by reason of the fact that he
or she is or was a director, officer, employee or other agent of PDC, or is or
was serving at the request of PDC as a director, officer, employee, or other
agent of another corporation, partnership, joint venture, trust, or other
enterprise, against expenses, judgments, fines, settlements and other amounts
actually and reasonably incurred in connection with that proceeding, if that
person acted in good faith and in a manner that person reasonably believed to
be in the best interests of PDC, and in actions by PDC with such care,
including reasonable inquiry, as an ordinarily prudent person in a like
position would use under similar circumstances, and, in the case of a criminal
proceeding, had no reasonable cause to believe the conduct of that person was
unlawful.
To the extent that any director, officer, employee or other agent of PDC has
been successful on the merits in defense of any proceeding referred to in the
bylaws, that person shall be indemnified against expenses actually and
reasonably incurred by that person in connection with that proceeding. 
Except as provided in the preceding sentence, any indemnification may be made
by PDC only if authorized in the specific case upon a determination that
indemnification of the director, officer, employee or other agent is proper in
the circumstances because that person has met the applicable standard of
conduct set forth in the bylaws by (a) a majority vote of a quorum consisting
of directors who are not parties to the proceeding; (b) approval by the
affirmative vote of a majority of the shares of PDC represented and voting at a
duly held meeting at which a quorum is present (which shares voting
affirmatively also constitute at least a majority of the required quorum); or
(c) the court in which the proceeding is or was pending, upon application made
by PDC or the subject person or the attorney or other person rendering the
services in connection with the defense, whether or not the application by the
subject person, attorney or other person is opposed by PDC.
Expenses incurred in defending any proceeding may be advanced by PDC before the
final disposition of the proceeding upon receipt of an undertaking by or on
behalf of the director, officer, employee or other agent of PDC to repay the
amount of the advance unless it shall be determined ultimately that the subject
person is entitled to be indemnified as authorized by the bylaws.
PDC's
Articles of Incorporation
provide that
no director or officer of PDC shall be personally liable to PDC or its
stockholders for monetary damages for breach of fiduciary duty as a director or
officer, except for liability for (i) an act or
omission that involves intentional misconduct, fraud or a knowing violation of
the law; (ii) an act or omission for which the liability of a director or
officer is expressly provided for by an applicable statute, including the
liability for payment of distributions in violation of Section 78.300 of the
Nevada Revised Statues; and (iii) any other act, omission, transaction or
breach of duty as to which any applicable statute, rule or regulation provides
that the liability of directors or officers may not be eliminated or limited.
Item 7.
Exemption from Registration Claimed.

Item 9.
Undertakings.
The undersigned hereby undertakes:
(1)        To file, during any period in
which offers or sales are being made, a post-effective amendment to this
registration statement:
(i)        
To include any prospectus required by section 10(a)(3)
of the Securities Act of 1933;
(ii)        To reflect in the prospectus any
facts or events arising after the effective date of the registration statement
(or the most recent post-effective amendment thereof) which, individually or in
the aggregate, represent a fundamental change in the information set forth in
the registration statement;
(iii)       To include any material information
with respect to the plan of distribution not previously disclosed in the
registration statement or any material change to such information in the
registration statement;
provided, however, that paragraph (1)(i) and (1)(ii) shall not apply
if the registration statement is on Form S-8, and if the information required
to be included in a post-effective amendment by those paragraphs is contained
in periodic reports filed with or furnished to the Commission by the registrant
pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934
that are incorporated by reference in the registration statement.
(2)        That, for the purpose of
determining any liability under the Securities Act of 1933, 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.
II-5
(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.
Filings Incorporating Subsequent
Exchange Act Documents by Reference
The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act
of 1934) 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.
Indemnification of Directors and
Officers
Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the 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 Act and
will be governed by the final adjudication of such issue.
