ITEM 4. DESCRIPTION OF SECURITIES

         Not Applicable.

ITEM 5. INTEREST OF NAMED EXPERTS AND COUNSEL

         None.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Section 7-109-102 of the Colorado Business Corporation Act, or the
CBCA, provides that a company may indemnify a person who was, is or is
threatened to be made a named defendant or respondant in any threatened, pending
or completed action, suit or proceeding, whether civil, criminal, administrative
or investigative and whether formal or informal (a "proceeding"), because the
person is or was a director, against liability incurred in the proceeding if the
person conducted himself or herself in good faith; and the person reasonably
believed, in the case of conduct in an official capacity with the company, that
his or her conduct was in the company's best interests, and in all other cases,
that his or her conduct was at least not opposed to the company's best
interests; and in the case of any criminal proceeding, the person had no
reasonable cause to believe his or her conduct was unlawful. A company may not
indemnify a director in connection with a proceeding by or in the right of the
company in which the director was adjudged liable to the company or in
connection with any other proceeding charging that the director derived an
improper personal benefit, whether or not involving action in an official
capacity, in which



                                      -2-




proceeding the director was adjudged liable on the basis that he or she derived
an improper personal benefit. Unless limited by its articles of incorporation,
Section 7-109-103 of the CBCA states that a company shall indemnify a person who
was wholly successful, on the merits or otherwise, in the defense of any
proceeding to which the person was a party because the person is or was a
director against reasonable expenses (including attorneys' fees) incurred in
connection with the proceeding. Unless otherwise provided in a company's
articles of incorporation, Section 7-109-107 of the CBCA states that an officer
is entitled to mandatory indemnification under Section 7-109-103 of the CBCA.
Section 7-109-107 also states that unless provided in its articles of
incorporation, a company may indemnify an officer, employee, fiduciary or agent
of the company to the same extent as a director.

         The Company's Articles of Incorporation provide that the Company may
and shall indemnify each director, officer and any employee or agent of the
Company, his heirs, executors and administrators, against any and all expenses
or liability reasonably incurred by him in connection with any action, suit or
proceeding to which he may be a party by reason of his being or having been a
director, officer, employee or agent of the Company to the full extent required
or permitted by the CBCA, as amended.

         Article XIII of the Company's Amended and Restated Bylaws states that
the Company may indemnify against liability incurred in any proceeding an
individual who was, is or is threatened to be made a named defendant or
respondant in any proceeding because he is or was a director if he conducted
himself in good faith; he reasonably believed, in the case of conduct in his
official capacity with the Company, that his conduct was in the Company's best
interests, or in all other cases, that his conduct was at least not opposed to
the Company's best interests; and in the case of any criminal proceeding, he had
no reasonable cause to believe his conduct was unlawful. The Company may not
indemnify a director in connection with a proceeding by or in the right of the
Company in which the director was adjudged liable to the Company or in
connection with any proceeding charging improper personal benefit to the
director, whether or not involving action in his official capacity, in which he
was adjudged liable on the basis that personal benefit was improperly received
by him. The Company shall indemnify a person who is or was a director or officer
of the Company and who was wholly successful, on the merits or otherwise, in
defense of any proceeding to which he was a party against reasonable expenses
incurred by him in connection with the proceeding.

         Under the sections of the CBCA and the Company's Bylaws, a "director"
includes an individual who is or was a director of a company or an individual
who, while a director of a company, is or was serving at the company's request
as a director, an officer, an agent, an associate, an employee, a fiduciary, a
manger, a member, a partner, a promoter or a trustee of, or to hold any similar
position with, another domestic or foreign corporation or other person or of an
employee benefit plan.

         The Company may purchase and maintain insurance on behalf of an
individual who is or was a director, officer, employee, fiduciary or agent of
the Company and who, while a director, officer, employee, fiduciary or agent of
the Company, is or was serving at the request of the Company as a director,
officer, partner, trustee, employee, fiduciary or agent of any other foreign or
domestic company or of any partnership, joint venture, trust, other enterprise
or employee benefit plan against any liability asserted against or incurred by
him in any such capacity or arising out of his status as such, whether or not
the Company would have the power to indemnify him against such liability under
the provisions of Article XIII of the Company's Bylaws. The Company currently
maintains a $1,000,000 insurance policy that covers directors' and officers'
liability.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to our directors, officers and controlling persons pursuant
to the foregoing provisions, or otherwise, we have been advised that in the
opinion of the SEC such indemnification is against public policy as expressed in
the Securities Act and is, therefore, unenforceable.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED

         None.

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 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, any
         increase or decrease in volume of securities offered (if the total
         dollar value of securities offered would not exceed that which was
         registered) and any deviation from the low or high end of the estimated
         maximum offering range may be reflected in the form of prospectus filed
         with the Commission pursuant to Rule 424(b) if, in the aggregate, the
         changes in volume and price represent no more than a 20% change in the
         maximum aggregate offering price set forth in the "Calculation of
         Registration Fee" table in the effective 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 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 with or furnished to the Commission by the Registrant
pursuant to Section 13 or Section 15(d) of the Exchange Act that are
incorporated by reference in the 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.



                                      -4-




         (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 Section 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 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 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 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.
