Item 6. Indemnification of Directors and Officers

     Subsection 1 of Section 78.7502 of the Nevada General  Corporation Law (the
"Nevada  Law")  empowers a  corporation  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 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 he 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 proceeding if he is not liable pursuant to Section 78.138 of the
Nevada Law or 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 proceeding, had no reasonable cause to believe
his conduct was unlawful.  Section 78.128 of the Nevada Law provides that,  with
certain  exceptions,  a director  or officer is not  individually  liable to the
corporation  or its  stockholders  for any  damages  as a  result  of any act or
failure to act in his capacity as a director or officer unless it is proven that
(i) his act or failure to act constituted a breach of his fiduciary  duties as a
director or officer,  and (ii) his breach of those duties  involved  intentional
misconduct, fraud or a knowing violation of the law.

     Subsection 2 of Section  78.7502  empowers a  corporation  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  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,
including amounts paid in settlement and attorneys' fees actually and reasonably
incurred by him in  connection  with the defense or settlement of such action or
suit if he acted under similar standards,  except that no indemnification may be
made in respect of any claim, issue or matter as to which such person shall have
been  adjudged  by a  court  of  competent  jurisdiction  to be  liable  to  the
corporation  or for amounts paid in  settlement to the  corporation,  unless and
only to the  extent  that the court in which  such  action  or suit was  brought
determines that,  despite the  adjudication of liability,  such person is fairly
and  reasonably  entitled  to  indemnity  for such  expenses  as the court deems
proper.

     Section 78.7502  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  subsections  (1) and (2),  or in the defense of any
claim,  issue  or  matter  therein,  he shall be  indemnified  against  expenses
(including   attorneys'  fees)  actually  and  reasonably  incurred  by  him  in
connection  therewith.  Section  78.751  of the  Nevada  Law  provides  that the
indemnification provided for by Section 78.7502 shall not be deemed exclusive or
exclude any other rights to which the indemnified party may be entitled and that
the scope of indemnification shall continue as to directors, officers, employees
or agents who have ceased to hold such positions,  and to their heirs, executors
and administrators. Section 78.752 of the Nevada Law empowers the corporation to
purchase and maintain  insurance on behalf of a director,  officer,  employee or
agent of the corporation  against any liability asserted against him or incurred
by him in any such  capacity or arising out of his status as such whether or not
the corporation  would have the power to indemnify him against such  liabilities
under Section 78.7502.

     Section 4.10 of the Bylaws of the Company provides for  indemnification  of
its officers and directors,  substantially  identical in scope to that permitted
under the above  Sections of the Nevada  Law.  The Bylaws  provide,  pursuant to
Subsection 2 of Section  78.751,  that the  expenses of officers  and  directors
incurred in defending any action, suit or proceeding, whether civil or criminal,
must be paid by the corporation as they are incurred and in advance of the final
disposition  of the action,  suit or proceeding,  upon delivery,  if required by
Nevada  law,  of an  undertaking  by or on behalf of the  director or officer to
repay all  amounts so  advanced  if it is  ultimately  determined  by a court of
competent  jurisdiction  that the  officer or  director  is not  entitled  to be
indemnified  by the  corporation.  The Company also enters into  indemnification
agreements  consistent  with  Nevada  law  with  certain  of its  directors  and
officers.  


Item 7. Exemption from Registration Claimed

     Not applicable.


Item 8. Exhibits

     See the attached  Exhibit Index at page 9, which is incorporated  herein by
reference.  

Item 9. Undertakings

     (a)  The undersigned registrant 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;

               (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 the
          aggregate, represent a fundamental change in the information set forth
          in this Registration Statement; and

               (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 (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 is contained in periodic  reports filed with or furnished
     to the Commission by the registrant  pursuant to Section 13 or 15(d) of the
     Exchange  Act that  are  incorporated  by  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. 

          (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 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  this  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.  

     (h) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, executive officers and controlling persons of
the  registrant  pursuant  to the  provisions  described  in  Item 6  above,  or
otherwise, the registrant has been advised that in the opinion of the 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,  the  Registrant
certifies  that it has  reasonable  grounds to believe  that it meets all of the
requirements  for  filing  on  Form  S-8 and  has  duly  caused  this  Form  S-8
Registration Statement to be signed on its behalf by the undersigned,  thereunto
duly  authorized,  in the  City of  Reno,  State of  Nevada,  on March 8,  2005.
