in a manner he reasonably believed to be in or not opposed to the best interests
of the Corporation, and (b) with respect to any claim, issue, or matter as to
which such person shall have been adjudged to be liable to the Corporation by a
court of competent jurisdiction after exhaustion of all appeals therefrom, or
with respect to amounts paid in

                                       15

settlement to the Corporation, the court in which such action or suit was
brought shall determine upon application that, despite the adjudication of
liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses as the court shall
deem proper.

      5.3 EXTENT. A person named in Section 5.1 shall be indemnified by the
Corporation, if he satisfies the applicable standards of Section 5.2, against
expenses (including attorneys' fees), judgments, fines, and amounts paid in
settlement actually and reasonably incurred by the person in connection with the
proceeding, subject to the limitation of clause (ii)(b) of Section 5.2, if
applicable.

      5.4 DETERMINATION. A determination that a person has satisfied the
standard for indemnification under Section 5.2 and a determination as to
reasonableness of expenses may be made by a court or may be made: (i) by the
stockholders of the Corporation; (ii) by the Board of Directors by a majority of
a quorum consisting of Directors of the Corporation who at the time of the vote
are not parties to the proceeding; or (iii) if such a quorum of Directors cannot
be obtained, or, even if obtainable a quorum of disinterested Directors so
directs, by independent legal counsel selected by the Board of Directors, in a
written opinion.

      5.5 PRORATION. A determination under Section 5.4 may include a
determination that a person has met the standard as to some matters, but not as
to others, and may reasonably prorate amounts to be indemnified.

      5.6 ADVANCE PAYMENT. Expenses (including attorneys' fees) incurred by an
officer or director in defending any civil, criminal, administrative, or
investigative proceeding shall be paid by the Corporation as they are incurred
in advance of the final disposition of such proceeding, and without any of the
determinations specified in Section 5.4, upon receipt of an

                                       16

undertaking by or on behalf of such officer or director to repay such amount if
it is ultimately determined by a court of competent jurisdiction that such
officer or director is not entitled to be indemnified by the Corporation. Such
expenses incurred by other employees and agents may be so paid upon such terms
and conditions, if any, as the Board of Directors deems appropriate.

      5.7 NONEXCLUSIVE AND CONSISTENT. The indemnification and advancements of
expenses provided by this Article V shall not be exclusive of any other rights
to which a person may be entitled by law, the Articles of Incorporation of the
Corporation, these Bylaws, agreement, vote of stockholders or disinterested
Directors, or otherwise. It is not the intent of the Corporation that any
provision of this Article V be inconsistent with the requirements and
limitations provided in Section 78.751 of the Nevada General Corporation Law and
to the extent that any provision hereof conflicts with any such requirement or
limitation, the provisions of Section 78.751 shall govern.

      5.8 CONTINUATION. The indemnification and advance payments provided by
this Article V shall continue as to a person who has ceased to hold a position
named in Section 5.1 and shall inure to his heirs, executors, and
administrators.

      5.9 INSURANCE. The Corporation may purchase and maintain insurance or make
other financial arrangements on behalf of any person who holds or who has held
any position named in 5.1, 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 has the authority to indemnify him against such
liability under this Article V or Section 78.751 of the Nevada General
Corporation Law. The Board of Directors shall determine the terms and conditions
of the insurance or other arrangement and the identity of the insurer or other
person participating in

                                       17

an arrangement. No financial arrangement made pursuant to this Section 5.9 may
provide protection for a person adjudged by a court of competent jurisdiction,
after exhaustion of all appeals therefrom, to be liable for intentional
misconduct, fraud or a knowing violation of the law, except with respect to the
advancement of expenses or indemnification ordered by a court.

                                       VI
                            EXECUTION OF INSTRUMENTS

      6.1 AUTHORIZATION. The Board of Directors may, in its discretion,
determine the method and designate the signatory officer or officers, or other
person or persons to execute any corporate instrument or document, or to sign
the corporate name, without limitation, except where otherwise provided by law,
and such execution or signature shall be binding upon the Corporation.

                                       VII
                         ISSUANCE AND TRANSFER OF SHARES

      7.1 SHARE CERTIFICATES. The Corporation shall deliver certificates
representing all shares to which stockholders are entitled, which certificates
shall be in such form as the Board of Directors may provide. Each certificate
shall bear upon its face the statement that the Corporation is organized in
Nevada, the name in which it is issued, the number and class of shares and
series, if any, and the par value or a statement that the shares are without par
value. The certificates shall be signed by the President or a Vice President and
by the Treasurer or an Assistant Treasurer, or the Secretary or an Assistant
Secretary, which signatures may be in facsimile if the certificates are to be
countersigned by a transfer agent and a registrar (which may be the same
institution if such institution countersigns certificates in both capacities),
and

                                       18

the seal of the Corporation shall be affixed thereto. The certificates shall
contain on the faces or backs such recitations or references as are required by
law.

      7.2 REPLACEMENT OF CERTIFICATES. No new certificates shall be issued until
the former certificate for the shares represented thereby shall have been
surrendered and cancelled, except in the case of lost or destroyed certificates
for which the Board of Directors may order new certificates to be issued upon
such terms, conditions, and guaranties as the Board of Directors may see fit to
impose, including the filing of a sufficient indemnity bond.

      7.3 TRANSFER OF SHARES. Shares of the Corporation may be transferred by
endorsement by the signature of the owner, his agent, attorney, or legal
representative, and the delivery of the certificate. The transferee in any
transfer of shares shall be deemed to have full notice of and consent to the
Bylaws of the Corporation to the same extent as if he had signed a written
assent thereto.

      7.4 REASONABLE DOUBTS AS TO RIGHT TO TRANSFER. When a transfer of shares
is requested and there is reasonable doubt as to the right of the person seeking
the transfer, the Corporation or its transfer agent, before recording the
transfer of the shares on its books or issuing any certificate therefor, may
require from the person seeking the transfer reasonable proof of his right to
the transfer. If there remains a reasonable doubt of the right to the transfer,
the Corporation may refuse a transfer unless the person gives adequate security
or a bond of indemnity executed by a corporate surety or by two individual
sureties satisfactory to the Corporation as to form, amount, and responsibility
of sureties. The bond shall be conditioned to protect the Corporation, its
officers, transfer agents, and registrars, or any of them, against any loss,
damage, expense, or other liability to the owner of the shares by reason of the
recordation of the transfer or the issuance of a new certificate for shares.

                               RECORDS AND REPORTS

      8.1 BOOKS AND RECORDS. All books and records provided for by statute shall
be open to inspection of the stockholders from time to time and to the extent
expressly provided by statute, and not otherwise. The Directors may examine such
books and records at all reasonable times.

      8.2 FIXING RECORD DATES FOR MEETINGS. For the purpose of determining
stockholders entitled to notice of or to vote at any meeting of stockholders or
any adjournment thereof, the Board of Directors of the Corporation may fix a
record date, which record date shall not be more than sixty (60) days before the
date of such meeting. A determination of stockholders of record entitled to
notice of or to vote at a meeting of stockholders shall apply to any adjournment
of the meeting; provided, however, that the Board of Directors may fix a new
record date for the adjourned meeting.

      8.3 FIXING RECORD DATES FOR CONSENTS TO ACTION. Unless a record date shall
have previously been fixed, whenever action by stockholders is proposed to be
taken by consent in writing without a meeting of the stockholders, the Board of
Directors may fix a record date for the purpose of determining the stockholders
entitled to consent to that action.

      8.4 FIXING RECORD DATES FOR DISTRIBUTIONS AND OTHER PURPOSES. In order
that the Corporation may determine the stockholders entitled to receive payment
of any dividend or other distribution or allotment of any rights or the
stockholders entitled to exercise any rights in respect of any change,
conversion or exchange of stock, or the for the purpose of any other lawful
action, the Board of Directors may fix a record date.

                               AMENDMENT OF BYLAWS

      9.1 AMENDMENT OF BYLAWS. The stockholders may amend or repeal these
Bylaws, or adopt new bylaws. The Board of Directors may also amend or repeal
these Bylaws, or adopt new bylaws, unless the stockholders in amending,
repealing, or adopting a particular bylaw expressly provide that the Board of
Directors may not amend or repeal that bylaw.
