Exhibit 99.3

On behalf of all Opportunity Bank of Montana employees, I would like to personally welcome you to the Opportunity Bank family. We are excited for the opportunity to combine Ruby Valley Bank with our company! I would like to congratulate all of you for the great job you’ve done over the past several years. Your performance is the primary factor to making this transaction so attractive to us at Opportunity Bank!

Opportunity Bank of Montana has a long history of serving its customers as a local Montana-based community bank. I plan to meet with you to personally introduce myself. We will also be paying a welcome bonus to you shortly after the purchase closes, to thank you for staying with Ruby Valley Bank and coming on board with us.

I recognize that you will have questions over the next few days and weeks as we prepare for the closing of the transaction early next year. Please rest assured that your questions will be answered as much as possible in advance. We are committed to keeping you informed and communicating with you in a timely manner. Enclosed with this letter is a brief overview of some of the benefits provided to full time employees. I will be visiting with you, accompanied by some of my staff, to provide more detailed information about employment with Opportunity Bank of Montana, and the plan to have you become familiar with Opportunity Bank’s products and services, and our operating systems.

The management of both Ruby Valley Bank and Opportunity Bank of Montana are committed to making this as seamless a transition as possible. Please feel free to contact Alana Binde, our Human Resources Officer, if you have any benefits-related questions. Her phone number is 406-457-4015 and her email address is abinde@oppbank.com. Thank you, and welcome to Opportunity Bank of Montana. I look forward to working together with all of you to meet the banking needs of our Montana communities.
