Dear Fellow Shareholder,


The AIRT Group is currently the largest shareholder of Insignia. We have been long-term investors going back to 2013. Our goal is to maximize shareholder value for all Insignia investors and we are excited about the future.


I am writing you today because we need your help. We have a proposal on the ballot that needs the voting support of our fellow investors. Proposal #6 deals with a unique and uncommon Minnesota state statute that prevents shareholders who own more than 20% of the outstanding shares from voting their shares over that 20% limit. We strongly believe in good corporate governance and that voting rights should match the economic interest that an investor has in a company. Unfortunately, that is not the case currently at Insignia and we need your support so that we may vote our full share position. By voting on Proposal #6 on the enclosed proxy card, you will help ensure that ALL Insignia shareholders have the same voting rights – i.e., one share one vote.


Please vote FOR proposal #6 today!!


Please keep in mind that we are not seeking to take control of the company. Voting for our proposal will not cost you anything and it does not dilute your share position. Your rights and shareholdings will NOT be impacted. You would be simply allowing us to have the ability to vote our full position. In addition, we have agreed with Insignia that we will not increase our share position above 33-1/3% for a period of two years.


The concept that one share should equal one vote is democratic and good corporate governance. Like you, we have purchased all of our shares in the market. We took the same investment risks that our fellow investors chose when buying shares in Insignia and we are here for the long-term. As I mentioned before, we are not seeking to take control of the company. We believe that there is real value in Insignia and that together, over time, all of us as shareholders can help unlock shareholder value.


I thank you for your time and consideration. Please vote FOR proposal #6 today. If you have any questions please contact our proxy advisor Alliance Advisors toll free at: 833-795-8496.



Best Regards,

/s/ Nicholas J. Swenson
