      (1) A record  shareholder may assert  dissenters'  rights as to fewer than

person and causes the  corporation  to receive  written notice which states such
dissent and the name, address,  and federal taxpayer  identification  number, if
any, of each person on whose behalf the record shareholder  asserts  dissenters'
rights.  The  rights  of a record  shareholder  under  this  subsection  (1) are
determined as if the shares as to which the record shareholder  dissents and the
other shares of the record shareholder were registered in the names of different
shareholders.

      (2) A  beneficial  shareholder  may  assert  dissenters'  rights as to the
shares held on the beneficial shareholder's behalf only if:

record shareholder's  written consent to the dissent not later than the time the
beneficial shareholder asserts dissenters' rights; and

      (b)  The  beneficial  shareholder  dissents  with  respect  to all  shares
beneficially owned by the beneficial shareholder.

      (3) The corporation may require that, when a record  shareholder  dissents
with respect to the shares held by any one or more beneficial shareholders, each
such beneficial  shareholder must certify to the corporation that the beneficial
shareholder  and the record  shareholder  or record  shareholders  of all shares
owned beneficially by the beneficial  shareholder have asserted,  or will timely
assert,  dissenters'  rights  as to all  such  shares  as to  which  there is no
limitation on the ability to exercise  dissenters'  rights. Any such requirement
shall be stated in the dissenters' notice given pursuant to section 7-113-203.

                                       3

title, would have been required to be given to shareholders  entitled to vote on
the  proposed  action  if the  proposed  action  were  submitted  to a vote at a
shareholders' meeting. Failure to give notice as provided by this subsection (2)

to  shareholders  of  the  terms  of  the  proposed  corporate  action  creating
dissenters'  rights under section  7-113-102 and state that the dissenter  shall
certify in writing,  in or with the  dissenter's  payment  demand under  section
7-113-204,  whether  or not  the  dissenter  (or  the  person  on  whose  behalf
dissenters'  rights are asserted)  acquired  beneficial  ownership of the shares
before  that  date.  With  respect to any  dissenter  who does not so certify in
writing,  in or with the payment  demand,  that the  dissenter  or the person on
whose  behalf the  dissenter  asserts  dissenters'  rights  acquired  beneficial
ownership of the shares before such date, the corporation may, in lieu of making
the payment  provided in section  7-113-206,  offer to make such  payment if the
dissenter agrees to accept it in full satisfaction of the demand.

      (2) An offer to make payment  under  subsection  (1) of this section shall
include or be accompanied by the information required by section 7-113-206 (2).

      (1) A  dissenter  may give  notice to the  corporation  in  writing of the
dissenter's  estimate  of the fair  value of the  dissenter's  shares and of the
amount of interest due and may demand payment of such estimate, less any payment
made under section  7-113-206,  or reject the corporation's  offer under section
7-113-208  and demand  payment of the fair value of the shares and interest due,
if:

      (a) The dissenter believes that the amount paid under section 7-113-206 or
offered  under  section  7-113-208  is less than the fair value of the shares or
that the interest due was incorrectly calculated;

                                       7


      (b) The corporation  fails to make payment under section  7-113-206 within

the  transfer  restrictions  imposed on  uncertificated  shares as  required  by
section 7-113-207 (1).

      (2) A  dissenter  waives the right to demand  payment  under this  section
unless the dissenter  causes the  corporation to receive the notice  required by
subsection (1) of this section within thirty days after the corporation  made or
offered payment for the dissenter's shares.

                          JUDICIAL APPRAISAL OF SHARES

      7-113-301. COURT ACTION.

      (1) If a demand for payment under section  7-113-209  remains  unresolved,
the  corporation  may,  within sixty days after  receiving  the payment  demand,
commence a proceeding  and petition the court to determine the fair value of the
shares and accrued interest. If the corporation does not commence the proceeding
within the sixty-day period, it shall pay to each dissenter whose demand remains
unresolved the amount demanded.

      (2) The corporation shall commence the proceeding  described in subsection
(1) of this section in the district  court of the county in this state where the
corporation's  principal  office  is  located  or,  if  the  corporation  has no
principal office in this state, in the district court of the county in which its
registered  office is  located.  If the  corporation  is a  foreign  corporation
without a registered  office,  it shall  commence the  proceeding  in the county
where the registered  office of the domestic  corporation  merged into, or whose
shares were acquired by, the foreign corporation was located.

      (3) The corporation shall make all dissenters, whether or not residents of
this state, whose demands remain unresolved parties to the proceeding  commenced
under  subsection (2) of this section as in an action against their shares,  and
all  parties  shall  be  served  with a copy of the  petition.  Service  on each
dissenter  shall be by  registered or certified  mail, to the address  stated in
such dissenter's  payment demand, or if no such address is stated in the payment
demand, at the address shown on the corporation's current record of shareholders
for the record  shareholder  holding the dissenter's  shares,  or as provided by
law.

      (4) The  jurisdiction  of the court in which the  proceeding  is commenced
under  subsection  (2) of this section is plenary and  exclusive.  The court may
appoint one or more persons as  appraisers  to receive  evidence and recommend a
decision on the question of fair value. The appraisers have the powers described
in the order  appointing them, or in any amendment to such order. The parties to
the  proceeding  are entitled to the same  discovery  rights as parties in other
civil proceedings.

      (5)  Each  dissenter  made a  party  to  the  proceeding  commenced  under
subsection  (2) of this section is entitled to judgment for the amount,  if any,
by which  the  court  finds  the  fair  value of the  dissenter's  shares,  plus
interest,  exceeds  the amount paid by the  corporation,  or for the fair value,
plus interest,  of the dissenter's  shares for which the corporation  elected to
withhold payment under section 7-113-208.

      7-113-302. COURT COSTS AND COUNSEL FEES.

      (1) The court in an appraisal proceeding commenced under section 7-113-301
shall  determine  all  costs  of  the   proceeding,   including  the  reasonable
compensation and expenses of appraisers  appointed by the court. The court shall
assess the costs against the corporation; except that the court may assess costs
against all or some of the dissenters,  in amounts the court finds equitable, to
the extent the court finds the dissenters acted arbitrarily, vexatiously, or not
in good faith in demanding payment under section 7-113-209.

      (2) The court may also assess the fees and expenses of counsel and experts
for the respective parties, in amounts the court finds equitable:

      (a) Against the  corporation  and in favor of any  dissenters if the court
finds the corporation did not substantially comply with the requirements of part
2 of this article; or

      (b) Against either the corporation or one or more dissenters,  in favor of
any other  party,  if the court finds that the party  against  whom the fees and
expenses are assessed acted arbitrarily,  vexatiously, or not in good faith with
respect to the rights provided by this article.

      (3) If the court finds that the services of counsel for any dissenter were
of substantial benefit to other dissenters similarly situated, and that the fees
for those services should not be assessed against the corporation, the court may
award to said counsel  reasonable  fees to be paid out of the amounts awarded to
the dissenters who were benefitted.
