 Asset Sale Proposal, the Advisory Compensation Proposal, and
the Adjournment Proposal in accordance with the recommendations of our board.

You may change or revoke your previously submitted
proxy at any time before the Special Meeting or, if you attend the Special Meeting virtually, at the Special Meeting before the polls
close.

If you hold your shares as a record holder, you
may change or revoke your proxy in any one of the following ways:

| ● | By re-voting at a subsequent time by Internet or by telephone as instructed                                                           
 above;                                                                                                                                |
| ● | By signing a new proxy card with a date later than your previously                                                                    
 delivered proxy and submitting it as instructed above;                                                                                |
| ● | By delivering a signed revocation letter to the following address:                                                                    
 P.O. BOX 8016, Cary, NC 27512-9903 c/o Mediant Communications; or                                                                     |
| ● | By attending the Special Meeting and voting virtually. Attending the                                                                  
 Special Meeting virtually will not in and of itself revoke a previously submitted proxy. You must specifically request at the Special 
 Meeting that it be revoked by voting at the Special Meeting.                                                                          |

Your latest-dated proxy card, Internet, or telephone
vote is the one that is counted.

If your shares are held in the name of a bank,
broker, or other nominee, you may change your voting instructions by following the instructions of your bank, broker, or other nominee.

Adjournments

The Asset Purchase Agreement permits us, under
certain limited circumstances described below, to postpone or adjourn the Special Meeting without the Buyer’s prior consent, provided,
however, that we may do so only after consultation with the Buyer.

Specifically, we are permitted to postpone or
adjourn the Special Meeting if:

| ● | a quorum is not present 
 at the Special Meeting; |

| ● | we have not received                                             
 a sufficient number of votes to approve the Asset Sale Proposal; |

| ● | our board determines                                                                         
 in good faith that a postponement or adjournment is necessary to comply with applicable laws 
 or regulations in connection with the approval of the Asset Sale Proposal; or                |

| ● | the SEC directs us to                    
 postpone or adjourn the Special Meeting. |

Any adjournment will allow stockholders of record
who have already sent in proxies to revoke them at any time prior to their use at the Special Meeting, as adjourned. See “Proposal 3: Adjournment Proposal”
