**** IMPORTANT REMINDER ****

The Special Meeting to Approve the Merger with Consolidated Communications is on October 8th

PLEASE TAKE ACTION AND VOTE TODAY

Dear Enventis Shareholder:

On the date that this letter was mailed, your shares are still unvoted and we have been endeavoring to reach you regarding Enventis’ upcoming Special Meeting on October 8, 2014 and time is running short.

The proposals you are being asked to vote upon are very important to your investment. Failure to submit a proxy or vote in person will have the same effect as a vote AGAINST approval of the Merger Agreement with Consolidated and the transactions contemplated thereby.

Should shareholders fail to approve the Merger, it could adversely affect Enventis' stock price,
which was anticipated to reflect an assumption that the Merger would be completed.

The proposals are fully discussed in the Proxy Statement which you should have already received. The fastest way to have your vote counted is to vote by telephone or Internet, instructions for which are included with this letter.

THE COMPANY URGES YOU TO VOTE AS SOON AS POSSIBLE.

If you need help voting, please call Morrow & Co., our proxy solicitor, at 1-888-681-0976.

Thank you for your attention to this very important matter.
