We may solicit offers to purchase securities directly
from the public from time to time. We may also designate agents from time to time to solicit offers to purchase securities from the public
on our behalf. The prospectus supplement relating to any particular offering of securities will name any agents designated to solicit
offers, and will include information about any commissions we may pay the agents, in that offering. Agents may be deemed to be “underwriters”
as that term is defined in the Securities Act.

From time to time, we and the selling shareholders
may sell securities to one or more dealers acting as principals. The dealers, who may be deemed to be “underwriters” as that
term is defined in the Securities Act, may then resell those securities to the public.

We and the selling shareholders may sell securities
from time to time to one or more underwriters, who would purchase the securities as principal for resale to the public, either on a firm-commitment
or best-efforts basis. If we or the selling shareholders sell securities to underwriters, we and the selling shareholders may execute
an underwriting agreement with them at the time of sale and will name them in the applicable prospectus supplement. In connection with
those sales, underwriters may be deemed to have received compensation from us or the selling shareholders in the form of underwriting
discounts or commissions and may also receive commissions from purchasers of the securities for whom they may act as agents. Underwriters
may resell the securities to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions
from the underwriters and/or commissions from purchasers for whom they may act as agents. The applicable prospectus supplement will include
any required information about underwriting compensation we or the selling shareholders pay to underwriters, and any discounts, concessions
or commissions underwriters allow to participating dealers, in connection with an offering of securities.

If we offer securities in a subscription rights
offering to our existing security holders, we may enter into a standby underwriting agreement with dealers, acting as standby underwriters.
We may pay the standby underwriters a commitment fee for the securities they commit to purchase on a standby basis. If we do not enter
into a standby underwriting arrangement, we may retain a dealer-manager to manage a subscription rights offering for us.
