INTRODUCTION
This Registration Statement on Form S-8
is filed by Electro Sensors, Inc., a Minnesota corporation, ("ELSE" or the "Company") to register 600,000
shares of its common stock issuable under its 2013 Equity Incentive Plan.
PART I
Pursuant to the note to Part I of Form
S-8, the information required by Items 1 and 2 of Form S-8 is not filed as a part of this Registration Statement.
PART II
Item 3.  Incorporation of Documents by Reference.
The following documents filed with the
Securities and Exchange Commission are hereby incorporated by reference:
(a)
The Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2015;
(b)
The Company's Definitive Proxy Statement filed March 14, 2016 for the 2016 Annual Meeting
of Shareholders;
(c)
The Company's Form 8-K dated April 20, 2016; and
(d)
All other reports filed pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act
since the end of the year ended December 31, 2015.
All documents subsequently filed by the
Company pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Securities Exchange Act of 1934 prior to the completion or termination
of this offering of shares of Common Stock will be deemed to be incorporated by reference in this Registration Statement and to
be a part hereof from the date of filing of such documents.
Item 4.  Description of Securities.
Common Stock
Under its Restated Articles of Incorporation,
the Company has authorized 10,000,000 shares of its common stock $0.10 par value.
Each share of common stock is entitled
to one vote on all matters submitted to a vote of the shareholders. Shareholders do not have cumulative voting rights. The absence
of cumulative voting rights generally means that the holders of a majority of the outstanding shares of common stock can elect
all the directors then standing for election.
Each share of common stock has an equal
and ratable right to receive dividends legally declared by the Board of Directors out of any funds legally available for the payment
for dividends. In the event of Company liquidation, dissolution or winding up, after satisfaction of amounts payable to creditors,
holders of common stock are entitled to share ratably, on a per share basis, in the assets available for distribution to the shareholders.
Holders of common stock are not entitled
to subscription or preemptive rights. All outstanding shares of common stock when issued in connection with the terms of the 2013
Equity Incentive Plan will be validly issued, fully paid and nonassessable.
The current transfer agent for the common
stock is American Stock Transfer & Trust Company.
Item 5.  Interests of Named Experts and Counsel.
Not applicable.
Item 6.  Indemnification of Directors and Officers.
Section 302A.521 of the Minnesota Statutes
and Article 5 of the Company's Amended and Restated Bylaws require, among other things, the indemnification of any person
made or threatened to be made a party to a proceeding by reason of acts or omissions performed in the person's official capacity
as an officer, director, employee or agent of the Company against judgments, penalties and fines (including attorneys' fees)
if the person is not otherwise indemnified, acted in good faith, received no improper benefit, reasonably believed that such conduct
was in the best interests of the Company, and, in the case of criminal proceedings, had no reason to believe the conduct was unlawful.
In addition, Section 302A.521, subd. 3, of the Minnesota Statutes requires payment by the Company, upon written request, of reasonable
expenses in advance of final disposition in certain instances if a decision as to required indemnification is made by a disinterested
majority of the Board of Directors present at a meeting at which a disinterested quorum is present, or by a designated committee
of the Board, by special legal counsel, by the shareholders or by a court. The Company also maintains insurance to assist in funding
indemnification of directors and officers for certain liabilities.
Item 7.  Exemption from Registration Claimed.
Not applicable.
Item 8.  Exhibits.
