Item 6.           Indemnification of Directors and Officers.

         Nevada law provides that Nevada corporations may include in their
articles of incorporation provisions eliminating or limiting the personal
liability of their directors and officers in shareholder actions brought to
obtain damages for alleged breaches of fiduciary duties, as long as the alleged
acts or omissions did not involve intentional misconduct, fraud, a knowing
violation of law or payment of dividends in violation of the Nevada statutes.
Nevada law also allows Nevada corporations to include in their articles of
incorporation or bylaws provisions to the effect that expenses of officers and
directors incurred in defending a civil or criminal action must be paid by the
corporation as they are incurred, subject to an undertaking on behalf of the
director or officer to repay such expenses if it is ultimately determined by a
court of competent jurisdiction that such officer or director is not entitled to
be indemnified by the corporation because he or she did not act in good faith
and in a manner reasonably believed to be in or not opposed to the best
interests of the corporation.


         The respective articles of incorporation of the Company and its Nevada
subsidiaries provide that a director or officer of such company shall not be
personally liable to such company or its shareholders for damages for any breach
of fiduciary duty as a director or officer, except for liability for (a) acts or
omissions which involve intentional misconduct, fraud or a knowing violation of
law, or (b) the payment of distributions in violation of Nevada Revised Statutes
("NRS") Section 78.300. In addition, NRS Section 78.751 and Article VII of the
bylaws of each of such companies, under certain circumstances, provide for the
indemnification of the officers and directors of such company against
liabilities they may incur in such capacities. A summary of the circumstances in
which such indemnification is provided for is set forth in the following
paragraph, but such summary is qualified in its entirety by reference to Article
VII of the bylaws of such company.


         In general, any director or officer of the Company or its Nevada
subsidiaries (each, an "Indemnitee") who was or is a party to, or is threatened
to be made a party to, or is otherwise involved in any threatened, pending or
completed action or suit (including, without limitation, an action, suit or
proceeding by or in the right of such company), whether civil, criminal,
administrative or investigative (a "Proceeding") by reason of the fact that the
Indemnitee is or was a director or officer of such company or is or was serving
in any capacity at the request of such company as a director, officer, employee,
agent, partner or fiduciary of, or in any other capacity for, another
corporation or any partnership, joint venture, trust or other enterprise shall
be indemnified and held harmless by such company for actions taken by the
Indemnitee and for all omissions to the full extent permitted by Nevada law
against all expense, liability and loss (including, without limitation,
attorneys' fees, judgments, fines, taxes, penalties and amounts paid or to be
paid in settlement) reasonably incurred or suffered by the Indemnitee in
connection with any Proceeding. The rights to indemnification specifically
include the right to reimbursement from such company for all reasonable costs
and expenses incurred in connection with the Proceeding and indemnification
continues as to an Indemnitee who has ceased to be a director or officer. The
board of directors may include employees and other persons as though they were
Indemnitees. The rights to indemnification are not exclusive of any other rights
that any person may have by law, agreement or otherwise.

         The respective bylaws of the Company and its Nevada subsidiaries
provide that such company may purchase and maintain insurance or make other
financial arrangements on behalf of any person who otherwise qualifies as an
Indemnitee under the foregoing provisions. Other financial arrangements to
assist the Indemnitee are also permitted, such as the creation of a trust fund,
the establishment of a program of self-insurance, the securing of such company's
obligation of indemnification by granting a security interest or other lien on
any assets (including cash) of such company and the establishment of a letter of
credit, guarantee or surety.

         The respective bylaws and articles of incorporation of the Company's
Colorado subsidiaries provide that those companies shall, to the full extent
permitted by the Colorado Business Corporation Act ("CBCA"), indemnify all of
their directors and officers. Sections 7-109-101 to 7-109-110 of the CBCA
provide in part that a corporation shall have the power to indemnify any person
who was or is a party, or is threatened to be made a party, to any threatened,
pending or completed action, suit or proceedings (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 other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceedings if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and with respect to any criminal action
or proceedings, had no reasonable cause to believe his conduct was unlawful.
Similar indemnity is authorized for such persons against expenses (including
attorneys' fees) actually and reasonably incurred in defense or settlement of
any threatened, pending or completed action or suit by or in the right of the
corporation, if such person acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the corporation, and
provided further that (unless a court of competent jurisdiction otherwise
provides) such person shall not have been adjudged liable to the corporation.
Any such indemnification may be made only as authorized in each specific case
upon a determination by the shareholders or disinterested directors that
indemnification is proper because the indemnitee has met the applicable standard
of conduct. The indemnitee is presumed to be entitled to indemnification and the
corporation has the burden of proof to overcome that presumption. Where an
officer or a director is successful on the merits or otherwise in the defense of
any action referred to above, the corporation must indemnify him or her against
the expenses which such officer or director actually or reasonably incurred.


         Additionally, the respective articles of incorporation and bylaws of
the Company's Colorado subsidiaries provide for mandatory indemnification of
directors to the fullest extent permitted by Colorado law. This provision does
not eliminate the liability of a director for (a) a breach of the director's
duty of loyalty to the corporation or its shareholders; (b) acts or omissions by
the director not in good faith or which involve intentional misconduct or a
knowing violation of law; (c) liability arising under Section 7-108-403 of the
CBCA (relating to distributions to shareholders in violation of the CBCA); or
(d) any transaction from which the director derived an improper personal
benefit.

                           (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. Notwithstanding the foregoing,

                                    provided, however, that paragraphs (a)(1)(i)
                                    and (a)(1)(ii) do not apply if the
                                    information required to be included in a
                                    post-effective amendment by those paragraphs

                                    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 a new
                           registration statement relating to the securities
                           offered therein, and the offering of such securities
                           at that time shall be deemed the initial bona fide
                           offering thereof.

                  (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
                  of 1933, each filing of the registrant's annual report
                  pursuant to Section 13(a) or Section 15(d) of the Securities
                  Exchange Act of 1934 that is incorporated by reference in this
                  Registration Statement shall be deemed a new registration
                  statement relating to the securities offered therein, and the
                  offering of such securities at that time shall be deemed the
                  initial bona fide offering thereof.


         (c)      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 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.

                                   SIGNATURES

         Pursuant to the requirements of the Securities Act of 1933, the
registrant hereby certifies that it has reasonable grounds to believe that it

duly authorized, in the City of Las Vegas, State of Nevada, on July 1, 2005.
