Item 4.  DESCRIPTION OF SECURITIES.

     Not applicable.


Item 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

     Not applicable.


Item 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Article IV of the Company's Amended and Restated Articles of
Incorporation provides that the personal liability of any director to the
Company or to its shareholders for monetary damages for any action taken or
any failure to take action, as a director, is eliminated to the fullest
extent permitted by Utah law.

     Article VI of the Company's Amended and Restated Articles of
Incorporation provides that the Company shall indemnify any person who is or
was a director, officer, employee or agent of the Company, or is or was
serving at the request of the Company as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise to the fullest extent permitted by the Utah
Revised Business Corporations Act (the "Corporation Act"), as the same may
hereafter be amended, or as permitted by law.

     Section 16-10a-902 ("Section 902") of the Corporation Act provides that
a corporation may indemnify any individual who was, is, or is threatened to
be made a named defendant or respondent (a "Party") in any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative and whether formal or informal (a
"Proceeding"), because he is or was a director of the corporation or, while a
director of the corporation, is or was serving at its request as a director,
officer, partner, trustee, employee, fiduciary or agent of another
corporation or other person or of an employee benefit plan (an "Indemnifiable
Director"), against any obligation incurred with respect to a Proceeding,
including any judgment, settlement, penalty, fine or reasonable expenses
(including attorneys' fees), incurred in the Proceeding if his conduct was in
good faith, he reasonably believed that his conduct was in, or not opposed
to, the best interests of the corporation, and, in the case of any criminal
Proceeding, he had no reasonable cause to believe his conduct was unlawful;
provided however, that, pursuant to Subsection 902(4), (i) indemnification
under Section 902 in connection with a Proceeding by or in the right of the
corporation is limited to payment of reasonable expenses (including
attorneys' fees) incurred in connection with the Proceeding and (ii) the
corporation may not indemnify an Indemnifiable Director in connection with a
Proceeding by or in the right of the corporation in which the Indemnifiable
Director was adjudged liable to the corporation, or in connection with any
other Proceeding charging that the Indemnifiable Director derived an improper
personal benefit, whether or not involving action in his official capacity,
in which Proceeding he was adjudged liable on the basis that he derived an
improper personal benefit.

     Section 16-10a-903 ("Section 903") of the Corporation Act provides that,
unless limited by its articles of incorporation, a corporation shall
indemnify an Indemnifiable Director who was successful, on the merits or
otherwise, in the defense of any Proceeding, or in the defense of any claim,
issue or matter in the Proceeding, to which he was a Party because he is or
was an Indemnifiable Director of the corporation, against reasonable expenses
(including attorneys' fees) incurred by him in connection with the Proceeding
or claim with respect to which he has been successful.

     In addition to the indemnification provided by Sections 902 and 903,
Section 16-10a-905 ("Section 905") of the Corporation Act provides that,
unless otherwise limited by a corporation's articles of incorporation, an
Indemnifiable Director may apply for indemnification to the court conducting
the Proceeding or to another court of competent jurisdiction.  On receipt of
an application and after giving any notice the court considers necessary, (i)
the court may order mandatory indemnification under Section 903, in which
case the court shall also order the corporation to pay the director's
reasonable expenses to obtain court-ordered indemnification, or (ii) upon the
court's

                                       3
<PAGE>

determination that the director is fairly and reasonably entitled to
indemnification in view of all the relevant circumstances and regardless of
whether the director met the applicable standard of conduct set forth in
Section 902 or was adjudged liable as described in Subsection 902(4), the
court may order indemnification as the court determines to be proper, except
that indemnification with respect to certain Proceedings resulting in a
director being found liable as described in Subsection 902(4) is limited to
reasonable expenses (including attorneys' fees) incurred by the director.

     Section 16-10a-904 ("Section 904") of the Corporation Act provides that
a corporation may pay for or reimburse the reasonable expenses (including
attorneys' fees) incurred by an Indemnifiable Director who is a Party to a
Proceeding in advance of the final disposition of the Proceeding if (i) the
director furnishes the corporation a written affirmation of his good faith
belief that he has met the applicable standard of conduct described in
Section 902, (ii) the director furnishes to the corporation a written
undertaking, executed personally or in his behalf, to repay the advance if it
is ultimately determined that he did not meet the required standard of
conduct, and (iii) a determination is made that the facts then known to those
making the determination would not preclude indemnification.

     Section 16-10a-907 of the Corporation Act provides that, unless a
corporation's articles of incorporation provide otherwise, (i) an officer of
the corporation is entitled to mandatory indemnification under Section 903
and is entitled to apply for court ordered indemnification under Section 905,
in each case to the same extent as an Indemnifiable Director, (ii) the
corporation may indemnify and advance expenses to an officer, employee,
fiduciary or agent of the corporation to the same extent as an Indemnifiable
Director, and (iii) a corporation may also indemnify and advance expenses to
an officer, employee, fiduciary or agent who is not an Indemnifiable Director
to a greater extent than the right of indemnification granted to
Indemnifiable Directors, if not inconsistent with public policy, and if
provided for by its articles of incorporation, bylaws, general or specific
action of its board of directors or contract.

     Indemnification may be granted pursuant to any other agreement, bylaw,
or vote of shareholders or directors.  The Company currently maintains no
policy of director's and officer's insurance for the benefit of the officers
and directors of the Company.  The foregoing description is necessarily
general and does not describe all details regarding the indemnification of
officers, directors or controlling persons of the Company.

Item 7.  EXEMPTION FROM REGISTRATION CLAIMED.

         Not applicable.


Item 8.  EXHIBITS.

         See the Exhibit Index on page 7.


Item 9.  UNDERTAKINGS.

         (a)  The undersigned Registrant hereby undertakes:

              (1)  To file, during any period in which offers or sales are being
         made of the securities registered hereby, 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 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;

                                       4
<PAGE>

                   (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 Registration Statement is on Form S-3 or Form S-8, and 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 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.

              (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 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 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.

     (2)  The Registrant's Quarterly Report on Form 10-Q for the quarter ended

          under the Securities Exchange Act of 1934, as amended (the "Exchange
          Act"), including any amendment or report filed under the Exchange Act
          for the purpose of updating such description.

     In addition, all documents subsequently filed by the Registrant pursuant
to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act, prior to the
filing of a post-effective amendment which indicates that all securities
offered have been sold or which deregisters all securities then remaining

Item 4.  DESCRIPTION OF SECURITIES.

     Not applicable.

Item 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

     Not applicable.

Item 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Article IV of the Company's Amended and Restated Articles of
Incorporation provides that the personal liability of any director to the
Company or to its shareholders for monetary damages for any action taken or
any failure to take action, as a director, is eliminated to the fullest
extent permitted by Utah law.

     Article VI of the Company's Amended and Restated Articles of
Incorporation provides that the Company shall indemnify any person who is or
was a director, officer, employee or agent of the Company, or is or was
serving at the request of the Company as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise to the fullest extent permitted by the Utah
Revised Business Corporations Act (the "Corporation Act"), as the same may
hereafter be amended, or as permitted by law.

     Section 16-10a-902 ("Section 902") of the Corporation Act provides that
a corporation may indemnify any individual who was, is, or is threatened to
be made a named defendant or respondent (a "Party") in any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative and whether formal or informal (a
"Proceeding"), because he is or was a director of the corporation or, while a
director of the corporation, is or was serving at its request as a director,
officer, partner, trustee, employee, fiduciary or agent of another
corporation or other person or of an employee benefit plan (an "Indemnifiable
Director"), against any obligation incurred with respect to a Proceeding,
including any judgment, settlement, penalty, fine or reasonable expenses
(including attorneys' fees), incurred in the Proceeding if his conduct was in
good faith, he reasonably believed that his conduct was in, or not opposed
to, the best interests of the corporation, and, in the case of any criminal
Proceeding, he had no reasonable cause to believe his conduct was unlawful;
provided however, that, pursuant to Subsection 902(4), (i) indemnification
under Section 902 in connection with a Proceeding by or in the right of the
corporation is limited to payment of reasonable expenses (including
attorneys' fees) incurred in connection with the Proceeding and (ii) the
corporation may not indemnify an Indemnifiable Director in connection with a
Proceeding by or in the right of the corporation in which the Indemnifiable
Director was adjudged liable to the corporation, or in connection with any
other Proceeding charging that the Indemnifiable Director derived an improper
personal benefit, whether or not involving action in his official capacity,
in which Proceeding he was adjudged liable on the basis that he derived an
improper personal benefit.

     Section 16-10a-903 ("Section 903") of the Corporation Act provides that,
unless limited by its articles of incorporation, a corporation shall
indemnify an Indemnifiable Director who was successful, on the merits or
otherwise, in the defense of any Proceeding, or in the defense of any claim,
issue or matter in the Proceeding, to which he was a Party because he is or
was an Indemnifiable Director of the corporation, against reasonable expenses
(including attorneys' fees) incurred by him in connection with the Proceeding
or claim with respect to which he has been successful.

     In addition to the indemnification provided by Sections 902 and 903,
Section 16-10a-905 ("Section 905") of the Corporation Act provides that,
unless otherwise limited by a corporation's articles of incorporation, an
Indemnifiable Director may apply for indemnification to the court conducting
the Proceeding or to another court of competent jurisdiction.  On receipt of
an application and after giving any notice the court considers necessary, (i)
the court may order mandatory indemnification under Section 903, in which
case the court shall also order the corporation to pay the director's
reasonable expenses to obtain court-ordered indemnification, or (ii) upon the
court's

                                       3
determination that the director is fairly and reasonably entitled to
indemnification in view of all the relevant circumstances and regardless of
whether the director met the applicable standard of conduct set forth in
Section 902 or was adjudged liable as described in Subsection 902(4), the
court may order indemnification as the court determines to be proper, except
that indemnification with respect to certain Proceedings resulting in a
director being found liable as described in Subsection 902(4) is limited to
reasonable expenses (including attorneys' fees) incurred by the director.

     Section 16-10a-904 ("Section 904") of the Corporation Act provides that
a corporation may pay for or reimburse the reasonable expenses (including
attorneys' fees) incurred by an Indemnifiable Director who is a Party to a
Proceeding in advance of the final disposition of the Proceeding if (i) the
director furnishes the corporation a written affirmation of his good faith
belief that he has met the applicable standard of conduct described in
Section 902, (ii) the director furnishes to the corporation a written
undertaking, executed personally or in his behalf, to repay the advance if it
is ultimately determined that he did not meet the required standard of
conduct, and (iii) a determination is made that the facts then known to those
making the determination would not preclude indemnification.

     Section 16-10a-907 of the Corporation Act provides that, unless a
corporation's articles of incorporation provide otherwise, (i) an officer of
the corporation is entitled to mandatory indemnification under Section 903
and is entitled to apply for court ordered indemnification under Section 905,
in each case to the same extent as an Indemnifiable Director, (ii) the
corporation may indemnify and advance expenses to an officer, employee,
fiduciary or agent of the corporation to the same extent as an Indemnifiable
Director, and (iii) a corporation may also indemnify and advance expenses to
an officer, employee, fiduciary or agent who is not an Indemnifiable Director
to a greater extent than the right of indemnification granted to
Indemnifiable Directors, if not inconsistent with public policy, and if
provided for by its articles of incorporation, bylaws, general or specific
action of its board of directors or contract.

     Indemnification may be granted pursuant to any other agreement, bylaw,
or vote of shareholders or directors.  The Company currently maintains no
policy of director's and officer's insurance for the benefit of the officers
and directors of the Company.  The foregoing description is necessarily
general and does not describe all details regarding the indemnification of
officers, directors or controlling persons of the Company.

Item 7.  EXEMPTION FROM REGISTRATION CLAIMED.

         Not applicable.

Item 8.  EXHIBITS.

         See the Exhibit Index on page 7.

Item 9.  UNDERTAKINGS.

         (a)  The undersigned Registrant hereby undertakes:

              (1)  To file, during any period in which offers or sales are being
         made of the securities registered hereby, 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 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;

                                       4
(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 Registration Statement is on Form S-3 or Form S-8, and 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 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.

              (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 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 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.
