Subscription Certificates evidencing a like number of Rights to be issued to
the Registered Holder. Any Registered Holder desiring to split-up, combine,
or exchange one or more Subscription Certificates shall make such request in
writing delivered to the Subscription Agent and shall surrender with such
written request properly endorsed Subscription Certificates to be so

participant in a recognized signature guarantee program. Upon any such
split-up, combination or exchange of a Subscription Certificate, the
Subscription Agent shall countersign and deliver to the Registered Holder a
Subscription Certificate or Subscription Certificates as so requested.

         7.       EXERCISE.  Rights may be exercised at any time during the
Offering Period upon the terms and conditions set forth in the Prospectus and
in this Agreement.

                  (a) Rights may be exercised by completing and executing the
exercise portion of the Subscription Certificate and delivering it to the
Subscription Agent along with payment of the Subscription Price for the
aggregate number of Common Shares subscribed prior to 5:00 p.m. Eastern
Standard Time on the Expiration Date.

                  (b) A subscription will be accepted by the Subscription
Agent if, prior to 5:00 p.m. Eastern Standard Time on the Expiration Date,
the Subscription Agent has received full payment for the Common Shares and a
notice of guaranteed delivery guaranteeing delivery of a properly completed
and executed Subscription Certificate. The Subscription Agent will not honor
a notice of guaranteed delivery unless a properly completed and executed
Subscription Certificate

<PAGE>

is received by the Subscription Agent by the close of business on the third
business day after the Expiration Date.

                  (c) The Subscription Price shall be paid in United States
dollars, by: (i) bank draft drawn upon a United States bank or a postal,
telegraphic or express money order payable to the Subscription Agent or (ii)
wire transfer of funds to the account maintained by the Subscription Agent
for such purpose: ___________________ Bank, ABA No. ____________, A/C
__________________.

                  (d) Once a Registered Holder has exercised Rights, such
exercise may not be revoked or rescinded.

                  (e) If a Registered Holder does not specify the number of
Rights being exercised on the Subscription Certificate, or if the payment by
the Registered Holder is not sufficient to pay the total purchase price for
all of the Common Shares that the Registered Holder indicated on the
Subscription Certificate, the Registered Holder will be deemed to have
exercised the maximum number of Rights that could be exercised for the amount
of the payment that it delivered to the Subscription Agent.

                  (f) If the Registered Holder's payment exceeds the
Subscription Price for all the Rights shown on its Subscription Certificate,
its payment will be applied, until depleted, to subscribe for Common Shares
in the following order: (i) to subscribe for the number of Common Shares, if
any, that such Registered Holder indicated on the Subscription Certificate
that it wished to purchase through its Basic Rights; (ii) to subscribe for
Common Shares until its Basic Rights have been fully exercised and (iii) to
subscribe for additional Common Shares pursuant to such Registered Holder's
Over-subscription Rights. Any excess payment remaining after the foregoing
allocation will be returned to the Registered Holder as soon as practicable
by mail, without interest or deduction.

         8.       OVER-SUBSCRIPTION RIGHTS. Common Shares not sold by the
Company through the exercise of Basic Rights will be offered, by means of
Over-subscription Rights, to the Registered Holders who have exercised all of
their Basic Rights. Registered Holders such as broker-dealers, banks, and
other professional intermediaries who hold shares on behalf of clients, may
participate in exercising the Over-subscription Rights for the client if the
client fully exercises all Basic Rights.

         All subscriptions pursuant to the exercise of Over-subscription
Rights will be fulfilled out of the Common Shares not required to satisfy the
Basic Rights which are exercised. If the Common Shares are not sufficient to
satisfy all subscriptions pursuant to the Over-subscription Rights, the
available Common Shares will be allotted PRO RATA among those Registered
Holders who exercised the Over-subscription Rights; provided, however, that
if such PRO RATA allocation results in any Registered Holder being allocated
a greater number of Common Shares than such Registered Holder subscribed for
pursuant to the exercise of such Registered Holder's Over-subscription
Rights, then such Registered Holder will be allocated only such number of
Common Shares as such Registered Holder subscribed for and the remaining
Common Shares will be allocated among all other Registered Holders exercising
Over-subscription Rights; provided further, however, that if all

                                       -5-

<PAGE>

available shares are not so allocated, the remaining available shares will be
allocated among those Registered Holders of Rights whose exercise of
Over-subscription Rights has not been fully satisfied, again based on the
number of rights evidenced by such Registered Holders' respective
Subscription Certificates.

         9.       POWER OF ATTORNEY. The Company hereby constitutes and
appoints the Subscription Agent as the Company's true and lawful attorney
in-fact, with full power in such capacity to endorse, deposit, negotiate, and
invest on behalf and for the account of the Company any checks, draft, wire
transfers or other payments received by the Subscription Agent as a payment
of the Subscription Price upon the exercise of Basic Rights and
Over-subscription Rights.

         10.      ESCROW AND INVESTMENT FUNDS.  The Subscription Agent shall:

                  (a) Maintain a record of the date and amount of each
payment of the Subscription Price received upon the exercise of Rights

address of the Registered Holder by whom or on whose behalf such payment was
made.

                  (b) Aggregate all payments received upon the exercise of
Basic Rights and deposit such payments in one or more interest bearing bank

designated by the Company, as soon as practicable after receipt of such
payments.

                  (c) Aggregate all payments received upon the exercise of
Over-subscription Rights and deposit such payments in one or more interest
bearing bank accounts, or invest such payments in Treasury bills or other
investments designated by the Company, as soon as practicable after receipt
of such payments.

                  (d) Retain the first $2,000.00 in interest paid in respect
of the bank accounts or other investments described in (b) and (c) above (in
addition to compensation for its services pursuant to Section 19) and pay to
the Company, in accordance with the provisions of Section 11, below, an
amount equal to all such interest in excess of $2,000.00.

                  (e) Keep payments received upon the exercise of Basic
Rights separate from payments received upon the exercise of the
Over-subscription Rights.

                  (f) Keep all funds deposited and invested in accounts in
the name of the  Company.

                  (g) Return as promptly as practicable to the Registered
Holder who made such payment, any payment of the Subscription Price not
accepted by the Company for any reason.

Basic Rights and the Over-subscription Rights to the Registered Holders as
soon as practicable after the Expiration Date provided that the Company shall
have provided such certificates for Common Shares to the Subscription Agent.

         14.      VALIDITY AND FORM OF SUBSCRIPTIONS. All questions
concerning the timeliness, validity, form and eligibility of any exercise of
Rights will be determined by the Company, whose determination will be final
and binding. The Company in its sole discretion may waive any defect or
irregularity, or may permit any defect or irregularity to be corrected,
within such time as the Company may determine, or the Company may reject, in
whole or in part, the purported exercise of any Right. Neither the Company
nor the Subscription Agent will be under any duty or obligation to give any
notification or to permit the cure of any defect or irregularity in
connection with the submission of any Subscription Certificate, the exercise
or attempt to exercise any Right, or the payment of the Subscription Price.
Subscriptions through the exercise of Rights will not be deemed to have been
received or accepted by the Company until all irregularities or defects have
been waived by the Company or cured to the satisfaction of, and within the
time allotted by, the Company in its sole discretion. The Subscription Agent
will promptly notify the Company in writing of all defects in the exercise of
any Rights. Subscription Certificates and funds received by the Subscription
Agent that are not properly executed or submitted, and as to which all
irregularities have not been timely waived or cured, shall be returned by the
Subscription Agent to the Registered Holder who submitted such Subscription
Certificate and/or payment.

         15.      AMENDMENT, EXTENSION OR TERMINATION OF THE RIGHTS OFFER.

Shares for which Registered Holders have subscribed pursuant to the

<PAGE>

exercise of Rights; (b) extend the Expiration Date to a later date; or (c)
amend or modify the terms of the Rights. If the Company amends the terms of
the Rights, an amended Prospectus will be distributed to holders of record of

holders of Rights who exercised their Rights prior to such amendment or
within four business days after the mailing of the amended Prospectus will be
given the opportunity to confirm the exercise of their Rights by executing
and delivering a consent form on or prior to the Expiration Date, as the same
may be extended or amended.

         16.      LOSS OR MUTILATION. Upon receipt by the Company and the
Subscription Agent of evidence, satisfactory to them, of the ownership and
loss, theft, destruction or mutilation of any Subscription Certificate, and

such reasonable charges, as the Company or the Subscription Agent may
prescribe.

         17.      LIABILITY OF SUBSCRIPTION AGENT. The Subscription Agent
shall not, by issuing and delivering Subscription Certificates or stock

issued upon the exercise of Rights are fully paid and nonassessable. The
Subscription Agent shall not be: (i) liable for any statement of fact made or
contained in this Agreement or in the Prospectus or in any documents prepared
by the Company in connection with the offer of Common Shares through the
Rights; (ii) liable for any action taken, suffered or omitted by it in

harmless the Subscription Agent from and against any and all losses, expenses
and liabilities, including judgments, costs and reasonable attorneys' fees,
