Attachment: Core Rationale & FAQs

From: Paul A. Jones

Dear GSB Employees,

We wanted to share some very important news with all our employees who have been such valued and supportive members of our bank family. Our holding company has entered into an agreement with First Busey Corporation, the holding company of Busey Bank, which will result in the combination of our financial institutions.

There will be a lot of information to share over the coming months, but at this time, we wanted to share the following important information:

1. The transaction is expected to be completed in the second quarter of 2021, subject to regulatory approval and the satisfaction of other customary closing conditions.

2. Busey Bank has acquired and integrated banks in many similar transactions, and we expect that the process will be completed in an efficient manner designed to minimize any disruption to banking services.

3. Paul Jones and John Diedrich plan to remain with the bank during the transition period of 6 to 8 months working as a team with Busey top management to assure a successful transition and incorporation of GSB into the Busey Bank family.

An important part of management’s leadership is the vision and planning for the future of our bank to serve the interests of our customers, our employees and the community we serve. During the last couple of years, the bank holding company has been carefully evaluating the best options for Glenview State Bank’s next decade of operation. It is essential to place our organization in a position to compete effectively in the market, grow the deposit base, increase loans and care for our employees. We also must position the bank to best serve, retain and grow our customer base.

Busey, like GSB, is one of the oldest Illinois-chartered banks. Busey Bank, which was founded in 1868, combines the benefits of a larger size bank, with assets of over $10 billion as of September 30, 2020, with the customer centric “Community Bank” approach to doing business. Senior management of GSB has great confidence in this combination. Reflecting this confidence, the bank holding company shareholders will hold a significant investment in the stock of Busey Bank’s holding company after the transaction is completed.

A goal of GSB senior management is to keep much of the GSB team together and we believe the Busey plan will help accomplish this goal. We will continue to maintain that “high touch” customer service, including having a live bank employee answer the phone and greet customers. We believe the combination with Busey Bank will also enable us to be an industry leader regarding the continuing implementation of new technologies. We believe we must adapt and implement these emerging technologies to prosper and remain a leader in our community.

We believe additional benefits to joining the Busey Bank family will become apparent once we join Busey Bank, including the following:

· Busey’s size and financial strength will enhance retail customer services in important areas such as mobile banking and online banking, enabling us to offer a greater breadth of financial services and products to our retail customers.

· As a part of Busey Bank, we will enhance our financial services and product offerings to our commercial accounts as well. In addition, we expect our customer lending limit will increase significantly. This will enable our commercial lending officers to target larger commercial accounts than in the past, and a broader number of market categories. This higher lending limit will also help us to retain commercial customers as they grow and require larger credit lines, revolvers and term loans.

· Our Trust department team has built the business to over $1 billion in assets under management. The combination with Busey will enable us to offer additional Trust and fiduciary products and services, and help us accelerate the growth of our trust business.

· While gaining the benefits of a larger scale by joining Busey, we will remain an Illinois-chartered bank with a community banking approach to business. In essence we will offer our customers the best of both worlds: scale and community banking services.

In joining Busey we will become part of one of the most dynamic banks headquartered in the State of Illinois. Busey Bank maintains over 50 banking centers stretching from Champaign-Urbana north to Chicago’s south, western and northern suburbs. The bank also maintains nearly 30 banking centers in the greater St. Louis area (Missouri and Illinois) and a branch in Carmel, Indiana. Finally, to better serve our snowbird customers, Busey Bank maintains four banking centers and a wealth management office in Southwest Florida.

We are confident that we have found a partner that shares the same philosophy of putting customers first AND supporting the communities it serves.

The timing of this announcement comes directly on the heels of our celebration of GSB’s 100-year anniversary. We are proud of this history of service, and look forward to continuing that legacy going forward with Busey Bank.

The complete rationale behind our strategic partnership with First Busey, key communication points, a link to an Integration Hub, where additional resources and information can be found, and a FAQ repository are included in the attachment.

There will be more information to come, including through a dedicated section of our web site at www.gsb.com and at www.busey.com/ourstory.

As always, we appreciate your support of true community banking; community banking that will remain intact for years to come.
