     EIGHTH: TRANSACTIONS WITH INTERESTED DIRECTORS AND OFFICERS. None of the
directors or officers of this Corporation shall, in the absence of fraud, be
disqualified by his office from contracting, leasing, or otherwise dealing with
this Corporation, either as a vendor, lessor, purchaser, or otherwise, of which
he shall be a member or in which he may have a pecuniary interest in any manner
be disqualified from doing business with the Corporation. No director or
officer, nor any firm, association or corporation or with which he is connected
as aforesaid shall be liable to account to this Corporation or its stockholders
for any profit realized by him from or through any such contract, lease or
transaction, it being the express intent and purpose of this Article to permit
this Corporation to buy or lease from, sell to or otherwise deal with
partnerships, firms or corporations of which the directors and officers are
affiliated or in which they or any of them may have a pecuniary interest, and
the contracts or leases of this Corporation, in the absence of fraud, shall not
be void or voidable or affected in any manner by reason of any such membership.
Common or interested directors may be counted in determining the presence of a
quorum at a meeting of the Board of Directors or a committee thereof which
authorizes, approves, or ratifies such contract or transaction. Nothing shall
prevent an officer or director from being directly or indirectly involved in a
business enterprise that is in the same or similar line of business of that of
the Corporation.

     NINTH: INDEMNIFICATION.

          1. The Corporation may 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,
     fiduciary, or agent of the Corporation or is or was serving at the request
     of the Corporation as a director, officer, employee, fiduciary or agent of
     another corporation, partnership, joint venture, trust, or other
     enterprise, against expenses (including attorney fees), judgments, fines,
     and amounts paid in settlement actually and reasonably incurred by him in
     connection with such action, suit, or proceeding, if he acted in good faith
     and in a manner he reasonably believed to be in 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. The termination of
     any action, suit, or proceeding by judgment, order, settlement, or
     conviction or upon a plea of nolo contendere or its equivalent shall not

<PAGE>

     of itself create a presumption that the person did not act in good faith
     and in a manner which he reasonably believed to be in the best interests of
     the Corporation and with respect to any criminal action or proceeding, had
     reasonable cause to believe his conduct was unlawful.

          2. The Corporation may 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 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, fiduciary or agent of
     another corporation, partnership, joint venture, trust or other enterprise
     against expenses (including attorney fees) actually and reasonably incurred
     by him in connection with the defense or settlement of such action or suit
     if he acted in good faith and in a manner he reasonably believed to be in
     the best interests of the Corporation; but no indemnification shall be made
     in respect of any claim, issue, or matter as to which such person has been
     adjudged to be liable for negligence or misconduct in the performance of
     his duty to the Corporation unless and only to the extent that the court in
     which such action or suit was brought determines upon application that,
     despite the adjudication of liability, but in view of all circumstances of
     the case, such person is fairly and reasonably entitled to indemnification
     for such expenses which such court deems proper.

          3. To the extent that a director, officer, employee, fiduciary or
     agent of a corporation has been successful on the merits in defense of any
     action, suit, or proceeding referred to in (1) or (2) or this Article Ninth
     or in defense of any claim, issue or matter therein, he shall be
     indemnified against expenses (including attorney fees) actually and
     reasonably incurred by him in connection therewith.

          4. Any indemnification under (1) or (2) of this Article Nine (unless
     ordered by a court) and as distinguished from (3) of this Article shall be
     made by the Corporation only as authorized in the specific case upon a
     determination that indemnification of the director, officer, employee,
     fiduciary or agent is proper in the circumstances because he has met the
     applicable standard of conduct set forth in (1) or (2) above. Such
     determination shall be made by the Board of Directors by a majority vote of
     a quorum consisting of directors who were not parties to such action, suit,
     or proceeding, or, if such a quorum is not obtainable, if a quorum of
     disinterested directors so directs, by independent legal counsel in a
     written opinion, or by the stockholders.

          5. Expenses (including attorney fees) incurred in defending a civil or
     criminal action, suit, or proceeding may be paid by the Corporation in
     advance of the final disposition of such action, suit, or proceeding as
     authorized in (3) or (4) above, upon receipt of an undertaking by or on
     behalf of the director, officer, employee, fiduciary or agent to repay such
     amount unless it is ultimately determined that he is entitled to be
     indemnified by the Corporation as authorized in this Article Nine.

          6. The indemnification provided by this Article Nine shall not be
     deemed exclusive of any other rights to which those indemnified may be
     entitled under any bylaw, agreement, vote of stockholders or disinterested
     directors, or otherwise, and any procedure provided for by any of the
     foregoing, both as to action in his official capacity and as to action in
     another capacity while holding such office, and shall continue as to a
     person who has ceased to be a director, officer, employee, fiduciary or
     agent and shall inure to the benefit of heirs, executors, and
     administrators of such a person.

<PAGE>

          7. The Corporation may purchase and maintain insurance on behalf of
     any person who is or was a director, officer, employee, fiduciary or agent
     of the Corporation, or who is or was serving at the request of the
     Corporation as a director, officer, employee, fiduciary or agent of another
     corporation, partnership, joint venture, trust, or other enterprise against
     any liability asserted against him and 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 liability under provisions of
     this Article Nine.

          8. Anything herein to the contrary notwithstanding, to the fullest
     extent permitted by the Colorado Business Corporation Act, as the same
     exists or may hereafter be amended, a director or officer of this
     Corporation shall not be liable to the Corporation or its stockholders for
     monetary damages for breach of fiduciary duty as a director or officer.

     TENTH: LOCATIONS OF MEETINGS. The Board of Directors and stockholders of
this Corporation shall have the right to hold their meetings outside of the
State of Colorado when deemed most convenient or to the best interests of the
Corporation.

     ELEVENTH: REGISTERED AGENT. The name of the Corporation's Registered Agent
and the street address in Colorado for such Registered Agent where service of

     TWELFTH: DISPOSITION OF CORPORATE ASSETS. The Board of Directors may at any
meeting, by a majority vote, sell, lease, exchange, and/or convey all of its
property and assets, including its good will and/or its corporate franchises,
upon such terms and conditions and for such consideration or considerations as
the Board of Directors in their sole discretion deem expedient and for the best
interest of the Corporation and said consideration or considerations may consist
in whole or in part of shares of stock and/or securities of any other
corporation or corporations; provided, however, in all such cases the
affirmative vote of the holders of a majority of the Common Stock of said
Corporation then issued and outstanding shall be voted in ratification of the
Board of Directors action, said vote to be taken at a special stockholders'
meeting of the Corporation, duly called for that purpose. Nothing herein shall
be construed to limit the power of the Board of Directors of the Corporation and
said Board shall have power in its sole discretion to sell, lease, exchange
and/or convey such parts or parcels of land or personal property or assets as
the Board of Directors determine are no longer necessary or expedient to be held
by the Corporation. It is, however, specifically understood that the Board of
Directors may at their discretion create a lien or mortgage on any or all of the
assets of the Corporation in order to borrow money should the Board of Directors
feel that it is necessary for the conduct of the business.

     THIRTEENTH: ACCESS TO CORPORATIONS BOOKS AND RECORDS BY STOCKHOLDERS.
Stockholders shall at all times have the right to examine the books of the
Corporation except as limited by these Articles of Incorporation. Such
examination as hereinafter provided shall be made only by the shareholder in
person, and no extract from the books or

records of the Corporation shall be permitted to be made by any shareholder(s)
of the Corporation. Such shareholder shall give assurance in writing
satisfactory to the Board of Directors that he does not desire the information
required or to be obtained by such inspection for the purpose of communicating
the same to others who are not stockholders and, further, that he will not
directly or indirectly disclose the Company's business or affairs to any person
or persons whomsoever.

No information in regard to the business or operations of the Corporation and no
copy of, or extract from, any of the books or records of the Corporation shall
be furnished to any person by any officer or director of the Corporation except
by direction and/or approval by the Board of Directors. Stockholders desiring
information in regard to the business or operations of the Corporation, or
desiring to make inspection of the books or records, shall first make
application in writing to the Board of Directors stating the specific purpose of
the application, the particular information desired and the books and records
required for that purpose by such shareholder before such examination, and shall
further satisfy the Board of Directors that said application is made in good
faith and that said examination will not be detrimental to the interests of the
Corporation.

     FOURTEENTH: REGISTERED HOLDER OF SHARES TREATED AS OWNER THEREOF. The
Corporation shall be entitled to treat the registered holder of any shares of
the Corporation as the owner thereof for all purposes, including all rights
deriving from such shares, and the Corporation shall not be bound to recognize
any equitable or other claim to, or interest in, such shares or rights deriving
from such shares on the part of any other person including without limiting the
generality hereof, a purchaser, assignee or transferee of such shares or rights
deriving from such shares, unless and until such other person becomes the
registered holder of such shares, whether or not the Corporation shall have
either actual or constructive notice of the claimed interest of such other
person. By way of example and not of limitation, until such other person has
become the registered holder of such shares, he shall not be entitled: to
receive notice of the meetings of the stockholders; to vote at such meetings; to
examine a list of the stockholders; to be paid dividends or other sums payable
to stockholders; or to own, enjoy and exercise any other rights deriving from
such shares against the Corporation.

     FIFTEENTH: CONTROL OVER BYLAWS. The Board of Directors shall have the power
to make and amend such prudential Bylaws as they deem proper and not
inconsistent with the Constitution or the laws of the United States or of this
State for the management of the property of this Corporation, the regulation and
government of its affairs, and for the certification and transfer of its stock.
