We conducted our reviews in accordance with the standards of the PCAOB.
A review of condensed consolidated interim financial statements consists principally of applying analytical procedures and making inquiries
of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance
with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a
whole. Accordingly, we do not express such an opinion.
