The Borrower agrees to execute and deliver such
instruments, documents, certificates, opinions, assurances, and actions as the Bank may request, to effect the purpose of the transaction described in this commitment letter. The Banks obligation to make the loan shall be subject to receipt by
the Bank of properly executed documents in form and substance satisfactory to the Bank and Banks counsel. All proceedings, agreements, instruments, documents, and other matters relating to the making of the loan, and all other transactions
herein contemplated, shall be satisfactory to the Bank and to Banks counsel. While our mutual efforts will be directed toward the closing of this transaction, we may require that the transaction be restructured or otherwise
modified.

This commitment is
issued in reliance on, and the validity and binding effect of this commitment shall be subject to, the accuracy of all information, representations, schedules, and other materials or data submitted by the Borrower on the Borrowers financial
standing and the financial standing of the principals of the Borrower as set forth in the financial statements and other information submitted by the Borrower to the Bank and in reliance on the Borrowers statements as to the value of the
Collateral and its intended usage, all of which is deemed material. Any misrepresentation of a material fact, whether intentional or otherwise, made prior to issuance of this commitment or any change of any material fact (in the business, assets,
operations, or conditions, financial or otherwise, of Borrower and/or any other party guarantying or pledging collateral on behalf of the Borrower) after the issuance hereof shall, at the Banks sole option, render this commitment void without
further notice to the Borrower. In such event, the Bank, at its sole option, may elect not to close the loan.

If the terms of this loan are satisfactory, please
sign, date and return the enclosed copy of this letter in the envelope provided. This commitment is effective for thirty (30) days from the date of this letter. This offer will expire if we have not closed the loan within ninety (90) days of the
commitment letter date. If you have any questions or desire clarification on the conditions, please give me a call at (724) 465-1430.

This commitment cannot be assigned to any other
party without the express written consent of S&T Bank.

I appreciate the opportunity to be of service to
you and look forward to a mutually beneficial relationship.
