Item 6.  Indemnification of Directors and Officers.

(a)  Bylaws and Articles of Incorporation

The Company's Bylaws provide that the Company shall indemnify any and all
persons who may serve or who have served at any time as directors or officers,
or who at the request of the Board of Directors of the Company may serve or at
any time have served as directors or officers of another corporation in which
the Company at such time owned or may own shares of stock or of which it was or
may be a creditor, and their respective heirs, administrators, successors and
assigns, against any and all expenses, including amounts paid upon judgments,
counsel fees and amounts paid in settlement (before or after suit is commenced),
actually and necessarily incurred by such persons in connection with the defense
or settlement of any claim, action, suit or proceeding in which they, or any of
them, are made parties, or a party, or which may be asserted against them or any
of them, by reason of being or having been directors or officers or a director
or officer of the Company, or of such other corporation, except in relation to
matters as to which any such director or officer or former director or officer
or person shall be adjudged in any action, suit or proceeding to be liable for
his own negligence or misconduct in the performance of his duty.  Such
indemnification shall be in addition to any other rights to which those
indemnified may be entitled under any law, by-law, amendment, vote of
stockholders or otherwise.

The Company's Articles of Incorporation provide that no director shall be
personally liable to the Company or any shareholder for monetary damages for
breach of fiduciary duty as a director, except for any matter in respect of
which such director shall be liable under Section 17-16-834 of the Wyoming
Business Company Act (the "WBCA") or any amendment thereto or successor
provision thereto, or shall be liable by reason that, in addition to any and all
other requirements for such liability, he (i) shall have breached his duty of
loyalty to the Company or its shareholders, (ii) shall not have acted in good
faith or, in failing to act, shall not have acted in good faith, (iii) shall
have acted in a manner involving intentional misconduct or a knowing violation
of law or, in failing to act, shall have acted in a manner involving intentional
misconduct or a knowing violation of law, (iv) shall have derived an improper
personal benefit, or (v) shall have voted for or assented to a distribution made
in violation of  Section 17-16-640 of the WBCA or the Articles of the Company if
it is established that he did not perform his duties in compliance with Section
17-16-830 of the WBCA.

(b)  Wyoming Business Corporation Act

The WBCA includes the following provisions:

17-16-850.  Subarticle definitions.

  (a)  In this subarticle:

         (i)   "Corporation" includes any domestic or foreign predecessor entity
         of a corporation in a merger;

         (ii)  "Director" or "officer" means an individual who is or was a
         director or officer, respectively, of a corporation or who, while a
         director or officer of the corporation, is or was serving at the
         corporation's request as a director, officer, partner, trustee,
         employee or agent of another domestic or foreign corporation,
         partnership, joint venture, trust, employee benefit plan or other
         entity. A director or officer is considered to be serving an employee
         benefit plan at the corporation's request if his duties to the
         corporation also impose duties on, or otherwise involve services by,
         him to the plan or to participants in or beneficiaries of the plan.
         "Director" or
                                     II-2
<PAGE>

         "officer" includes, unless the context requires otherwise, the estate
         or personal representative of a director or officer;

         (iii) "Disinterested director" means a director who, at the time of a
         vote referred to in W.S. 17-16-853(c) or a vote or selection referred
         to in W.S. 17-16-855(b) or (c), is not:

               (A)  A party to the proceeding; or

               (B)  An individual having a familial, financial, professional or
               employment relationship with the director whose indemnification
               or advance for expenses is the subject of the decision being
               made, which relationship would, in the circumstances, reasonably
               be expected to exert an influence on the director's judgment when
               voting on the decision being made.

         (iv)  "Expenses" includes counsel fees;

         (v)   "Liability" means the obligation to pay a judgment, settlement,
         penalty, fine (including an excise tax assessed with respect to an
         employee benefit plan), or reasonable expenses incurred with respect to
         a proceeding;

         (vi)  "Party" means an individual who was, is or is threatened to be
         made, a defendant or respondent in a proceeding;

         (vii) "Proceeding" means any threatened, pending or completed action,
         suit or proceeding, whether civil, criminal, administrative,
         arbitrative or investigative and whether formal or informal.

17-16-851.  Authority to indemnify.

  (a)  Except as otherwise provided in this section, a corporation may indemnify
an individual who is a party to a proceeding because he is a director against
liability incurred in the proceeding if:

         (i)   He conducted himself in good faith; and

         (ii)  He reasonably believed that his conduct was in or at least not
         opposed to the corporation's best interests; and

         (iii) In the case of any criminal proceeding, he had no reasonable
         cause to believe his conduct was unlawful; or

         (iv)  He engaged in conduct for which broader indemnification has been
         made permissible or obligatory under a provision of the articles of
         incorporation, as authorized by W.S. 17-16-202(b)(v).

  (b)  A director's conduct with respect to an employee benefit plan for a
purpose he reasonably believed to be in the interests of the participants in and
beneficiaries of the plan is conduct that satisfies the requirement of paragraph
(a)(ii) of this section.

                                     II-3
<PAGE>

  (c)  The termination of a proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere or its equivalent, is not, of
itself, determinative that the director did not meet the standard of conduct
described in this section.

  (d)  Unless ordered by a court under W.S. 17-16-854(a)(iii), a corporation may
not indemnify a director under this section:

       (i)   In connection with a proceeding by or in the right of the
       corporation, except for reasonable expenses incurred in connection with
       the proceeding if it is determined that the director has met the
       standard of conduct under subsection (a) of this section; or

       (ii)  In connection with any proceeding with respect to conduct for
       which he was adjudged liable on the basis that he received a financial
       benefit to which he was not entitled.

  (e)  Repealed By Laws 1997, ch. 190, (S) 3.

17-16-852.  Mandatory indemnification.

A corporation shall indemnify a director who was wholly  successful, on the
merits or otherwise, in the defense of any  proceeding to which he was a party
because he was a director of  the corporation against reasonable expenses
incurred by him in connection with the proceeding.

17-16-853.  Advance for expenses.

  (a)  A corporation may, before final disposition of a proceeding, advance
funds to pay for or reimburse the reasonable expenses incurred by a director who
is a party to a proceeding because he is a director if he delivers to the
corporation:

         (i)   A written affirmation of his good faith belief that he has met
         the standard of conduct described in W.S. 17-16-851 or that the
         proceeding involves conduct for which liability has been eliminated
         under a provision of the articles of incorporation as authorized by
         W.S. 17-16-202(b)(iv); and

        (ii)   His written undertaking to repay any funds advanced if he is not
        entitled to mandatory indemnification under W.S.17-16-852 and it is
        ultimately determined that he has not met the standard of conduct
        described in W.S. 17-16-851.

        (iii)  Repealed By Laws 1997, ch. 190, (S) 3.

  (b)   The undertaking required by paragraph (a)(ii) of this section shall be
an unlimited general obligation of the director but need not be secured and may
be accepted without reference to the financial ability of the director to make
repayment.

  (c)  Authorizations under this section shall be made:

         (i)   By the board of directors:

                 (A)  If there are two (2) or more disinterested directors, by a
                 majority vote of all the disinterested directors (a majority of
                 whom shall for such purpose constitute a quorum) or

                                     II-4
<PAGE>

                 by a majority of the members of a committee of two (2) or more
                 disinterested directors appointed by such a vote; or

                 (B)  If there are fewer than two (2) disinterested directors,
                 by the vote necessary for action by the board in accordance
                 with W.S. 17-16-824(c), in which authorization directors who do
                 not qualify as disinterested directors may participate; or

         (ii)  By the shareholders, but shares owned by or voted under the
         control of a director who at the time does not qualify as a
         disinterested director may not be voted on the authorization.

17-16-854. Court-ordered indemnification and advance for expenses.

  (a)  A director who is a party to a proceeding because he is a director may
apply for indemnification or an advance for expenses to the court conducting the
proceeding or to another court of competent jurisdiction.  After receipt of an
application and after giving any notice it considers necessary, the court shall:

         (i)   Order indemnification if the court determines that the director
         is entitled to mandatory indemnification under W.S. 17-16-852;

         (ii)  Order indemnification or advance for expenses if the court
         determines that the director is entitled to indemnification or advance
         for expenses pursuant to a provision authorized by W.S.17-16-858(a); or

         (iii) Order indemnification or advance for expenses if the court
         determines, in view of all the relevant circumstances, that it is fair
         and reasonable:

               (A)  To indemnify the director; or

               (B)  To advance expenses to the director, even if he has not met
               the standard of conduct set forth in W.S. 17-16-851(a), failed to
               comply with W.S. 17-16-853 or was adjudged liable in a proceeding
               referred to in W.S. 17-16-851(d)(i) or (ii), but if he was
               adjudged so liable his indemnification shall be limited to
               reasonable expenses incurred in connection with the proceeding.

  (b)  If the court determines that the director is entitled to indemnification
under paragraph (a)(i) of this section or to indemnification or advance for
expenses under paragraph (a)(ii) of this section, it shall also order the
corporation to pay the director's reasonable expenses incurred in connection
with obtaining court-ordered indemnification or advance for expenses.  If the
court determines that the director is entitled to indemnification or advance for
expenses under paragraph (a)(iii) of this section, it may also order the
corporation to pay the director's reasonable expenses to obtain court-ordered
indemnification or advance for expenses.

17-16-855.  Determination and authorization of indemnification.

  (a)  A corporation may not indemnify a director under W.S. 17-16-851 unless
authorized for a specific proceeding after a determination has been made that
indemnification of the director is permissible because he has met the standard
of conduct set forth in W.S. 17-16-851.

  (b)  The determination shall be made:

                                     II-5
<PAGE>

         (i)   If there are two (2) or more disinterested directors, by the
         board of directors by majority vote of all the disinterested directors
         (a majority of whom shall for such purpose constitute a quorum), or by
         a majority of the members of a committee of two (2) or more
         disinterested directors appointed by such a vote;

         (ii)  Repealed By Laws 1997, ch. 190, (S) 3.

         (iii) By special legal counsel:

                 (A)  Selected in the manner prescribed in paragraph (i) of this
                 subsection; or

                 (B)  If there are fewer than two (2) disinterested directors,
                 selected by the board of directors (in which selection
                 directors who do not qualify as disinterested directors may
                 participate); or

         (iv)  By the shareholders, but shares owned by or voted under the
         control of a director who at the time does not qualify as a
         disinterested director may not be voted on the determination.

  (c)  Authorization of indemnification shall be made in the same manner as the
determination that indemnification is permissible, except that if there are
fewer than two (2) disinterested directors, authorization of indemnification
shall be made by those entitled under paragraph (b)(iii) of this section to
select special legal counsel.



17-16-856.  Officers.

  (a)  A corporation may indemnify and advance expenses under this subarticle to
an officer of the corporation who is a party to a proceeding because he is an
officer of the corporation:

         (i)   To the same extent as a director; and

         (ii)  If he is an officer but not a director, to such further extent as
         may be provided by the articles of incorporation, the bylaws, a
         resolution of the board of directors or contract, except for:

                 (A)  Liability in connection with a proceeding by or in the
                 right of the corporation other than for reasonable expenses
                 incurred in connection with the proceeding; or

                 (B)  Liability arising out of conduct that constitutes:

                         (I)   Receipt by him of a financial benefit to which he
                         is not entitled;

                         (II)  An intentional infliction of harm on the
                         corporation or the shareholders; or

                         (III) An intentional violation of criminal law.

         (iii)  A corporation may also indemnify and advance expenses to a
         current or former officer, employee or agent who is not a director to
         the extent, consistent with public policy, that may be

                                     II-6
<PAGE>

         provided by its articles of incorporation, bylaws, general or specific
         action of its board of directors or contract.

  (b)  The provisions of paragraph (a)(ii) of this section shall apply to an
officer who is also a director if the basis on which he is made a party to the
proceeding is an act or omission solely as an officer.

  (c)  An officer of a corporation who is not a director is entitled to
mandatory indemnification under W.S. 17-16-852, and may apply to a court under
W.S. 17-16-854 for indemnification or an advance for expenses, in each case to
the same extent to which a director may be entitled to indemnification or
advance for expenses under those provisions.

17-16-857.  Insurance.

A corporation may purchase and maintain insurance on behalf of an individual who
is a director or officer of the corporation, or who, while a director or officer
of the corporation, serves at the corporation's request as a director, officer,
partner, trustee, employee or agent of another domestic or foreign corporation,
partnership, joint venture, trust, employee benefit plan or other entity,
against liability asserted against or incurred by him in that capacity or
arising from his status as a director or officer whether or not the corporation
would have power to indemnify or advance expenses to him against the same
liability under this subarticle.


17-16-858.  Variation by corporate action; application of subarticle.

  (a)  A corporation may, by a provision in its articles of incorporation or
bylaws or in a resolution adopted or a contract approved by its board of

giving rise to a proceeding to provide indemnification in accordance with
W.S.17-16-851 or advance funds to pay for or reimburse expenses in accordance

Item 9.  Undertakings

  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 hereof) which, individually or in the aggregate, represent
  a fundamental change in the information set forth in the 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 (1)(i) and (1)(ii) shall 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 section 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 herein, 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.

  (4)  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 that is incorporated by reference in this
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

  (5)  To deliver or cause to be delivered with the prospectus, to each person
to whom the prospectus is sent or given, the latest annual report to security
holders that is incorporated by reference in the prospectus and furnished
pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 promulgated
under the Exchange Act; and, where interim financial information required to be
presented by Article 3 of Regulation S-X is not set forth in the prospectus, to
deliver, or cause to be delivered to each person to whom the prospectus is sent
or given, the latest quarterly report that is specifically incorporated by
reference in the prospectus to provide such interim financial information.

  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 foregoing provisions, 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

                                     II-9
<PAGE>

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.
