ProLung, Inc. Releases Communication Urging
Stockholders Not to Respond to Consent Solicitation by Steven C. Eror

Salt Lake City, UT, August 15, 2018 – ProLung, Inc. (“ProLung” or the “Company”) today released a communication urging stockholders not to respond to the consent solicitation by Steven C. Eror. The Company announced that stockholders will soon receive consent revocation materials and a GOLD consent revocation card from the Company, which they can use to decline or revoke consent to the actions proposed by Mr. Eror. The complete text of the Company’s letter to stockholders follows:

On August 6, 2018, Steven C. Eror, along with other parties acting in concert with Mr. Eror, filed with the U.S. Securities and Exchange Commission (the “SEC”) a preliminary consent statement on Schedule 14A, purporting to ask you, the owners of ProLung, to approve certain amendments to the Company’s First Amended & Restated Bylaws (the “Bylaws”) related to the size and composition of the Company’s Board of Directors (the “Board”) and to elect up to eight individuals nominated by Mr. Eror, including Mr. Eror himself, to the Board effective immediately. Mr. Eror’s consent solicitation is aimed at taking control of the Company. As a result, you may receive consent solicitation materials from Mr. Eror seeking your written consent to take these actions. We note that you may have also previously received materials from Mr. Eror in connection with this consent solicitation that have not, to date, been publicly filed with the SEC as required by applicable federal securities laws and regulations.

YOUR BOARD OF DIRECTORS VIGOROUSLY OPPOSES MR. EROR’S
ATTEMPT TO TAKE CONTROL OF THE BOARD AND THE COMPANY

WE STRONGLY URGE YOU NOT TO SIGN OR RETURN ANY CONSENT
CARD THAT YOU MAY RECEIVE FROM MR. EROR AND TO WAIT FOR THE GOLD CONSENT REVOCATION CARD FROM THE COMPANY

We believe that the election of Mr. Eror to the Board, along with his hand-selected group of seven nominees, would be highly detrimental to the Company and our stockholders. As previously announced, on June 27, 2018, the Company terminated Steven C. Eror as Chief Executive Officer of the Company for cause, and Mr. Eror subsequently resigned from the Board. This termination was the result of an investigation conducted by the Audit Committee of the Board, which was initiated after the Chairman of our Audit Committee received a number of confidential communications from employees identifying concerns of various types associated with Mr. Eror in his position as Chief Executive Officer. Based on evidence gathered during this investigation, the Board voted to terminate Mr. Eror’s employment for cause.

Soon, the Company will file with the SEC and send you a consent revocation statement, an accompanying GOLD consent revocation card and other communications, which will explain in more detail the Board’s reasons for terminating Mr. Eror’s employment as CEO of the Company and for opposing Mr. Eror’s attempt to gain control of the Company. Your Board recommends that you carefully review the Company’s consent revocation statement when it becomes available and all other communications that we will be sending to you regarding this matter.

We strongly urge you to WAIT for the consent revocation statement and GOLD consent revocation card from the Company. In the meantime, your Board urges you to take NO ACTION in regard to the consent solicitation conducted by Mr. Eror and others. In particular, your Board recommends that you do NOT sign or return any consent card that has been or may be sent to you by or on behalf of Mr. Eror, including any consents that you may have received that have not been filed with the SEC. If you have previously signed and returned a consent card, you can revoke it by signing, dating and returning the GOLD consent revocation card that will accompany the Company’s consent revocation statement.
