To our valued partners,

First and foremost, the health and safety of our employees, customers, and everyone that is part of our
TVI family is our top priority. We are diligently taking all the necessary precautions to keep everyone
protected during this time.

As it stands, our office and warehouse are open and operating as usual. Our factory is up and running as
usual. Material pick up is still available, and our shipping capabilities are continuing. Should this need to
change, our organization is fully prepared to serve our customers without disruption. Over the past year,
we have invested in technology that allows our staff to work off site if necessary. All phone messages are
sent directly to our email, so that we can respond. Now more than ever, these advances will allow us to
continue to meet the needs of our partners as we always have.

Our commitment to providing the best support to our customers and partners remains unchanged, but if
there is any way we could better serve you, please let us know.

We are sending our sincerest wishes for good health during this time.

Mark Creyer
Vice President Sales and Marketing
