Dear Burling Bank Clients –

We are pleased to share an exciting status update regarding the pending purchase transaction of
Burling Bank by LevelField Financial, Inc. that has been awaiting regulatory approval. The Illinois banking
regulator has conditionally approved LevelField’s acquisition and change of control of Burling Bank, and
we expect the transaction to be completed in the coming weeks once all closing conditions have been
satisfied.

As previously noted, Burling’s leadership, staff, location, products, and services will remain in place as a
part of the combined offering with LevelField. Importantly, you will enjoy the same exceptional banking
experience that the Burling team has worked hard to deliver to you for more than three decades.

The future of banking is evolving rapidly, and it’s imperative that Burling continues to embrace
innovation and emerging opportunities in order to remain relevant and provide sustained value to our
client base. By partnering with LevelField, we believe the combined entity secures our desire to give
Burling clients the best of both worlds – reliable traditional banking alongside new products and services
in emerging markets, including digital assets.

As the center of trust, we feel that a regulated bank can provide the necessary transparency and
stability that is often missing in new marketplaces, including digital assets. Further, our long history in
the financial exchange community provides a unique opportunity to take a leadership role and
contribute needed industry knowledge and regulatory experience.

It’s been thirty-six years since David Goldberg founded Burling Bank as a boutique bank for the trading
community. While much has changed since then, much remains the same: treat your clients well,
reward your staff, embrace new opportunities, and always conduct yourself and your business with
integrity.

Your relationship with Burling is central to our success and we welcome the opportunity to address any
questions that you may have. Please feel free to contact us and we’ll arrange a time to speak.
On behalf of every member of the Burling team, we appreciate your continued confidence and look
forward to a promising future together.

With gratitude,
