EXHIBIT C

SUMMARY OF RIGHTS TO PURCHASE

PREFERRED STOCK

On March 23, 1998, the Board of Directors of Perceptron, Inc. (the "Company") declared a dividend distribution of one Right for each outstanding share of Common Stock, $.01 par value (the "Common Stock"), of the Company.  The distribution was paid to the Company's shareholders of record on April 6, 1998 (the "Record Date") on April 8, 1998.

Effective August 20, 2018, August 20, 2015 and March 17, 2008, the Board of Directors of the Company amended the Rights.  This Summary describes the terms of the Rights, as amended.  Each Right entitles the registered holder to purchase from the Company one one-hundredth of a share of Series A Preferred Stock, no par value (the "Preferred Stock") at a price of $73.00 per one one-hundredth of a share (the "Purchase Price"), subject to adjustment.  The description and terms of the Rights are set forth in a First Amended and Restated Rights Agreement (the "Rights Agreement") between the Company and American Stock Transfer & Trust Company, LLC as Rights Agent, as amended on August 20, 2018 (the "Rights Agent").

Until the earlier to occur of (i) ten business days following a public announcement that a person or group of affiliated or associated persons (an "Acquiring Person") acquired, or obtained the right to acquire, beneficial ownership of 20% or more of the outstanding shares of the Common Stock (such public announcement date being the "Shares Acquisition Date") (or, if pursuant to a Permitted Offer (as defined below) such later date as fixed by the Board of Directors) or (ii) ten business days (or such later date as may be determined by the Board of Directors prior to such time as any person becomes an Acquiring Person) following the commencement or announcement of an intention to commence a tender offer or exchange offer by any person if, upon consummation thereof, such person would be an Acquiring Person, other than as a result of a Permitted Offer (as defined below), (the earlier of such dates being called the "Distribution Date"), the Rights are, with respect to any of the Common Stock certificates outstanding as of April 6, 1998, evidenced by such Common Stock certificate.  The Rights Agreement provides that, until the Distribution Date, the Rights will be transferred with and only with the Common Stock.  Until the Distribution Date (or earlier redemption, exchange or expiration of the Rights), new Common Stock certificates issued after April 6, 1998 upon transfer or new issuance of the Common Stock will contain a notation incorporating the Rights Agreement by reference.  Until the Distribution Date (or earlier redemption, exchange or expiration of the Rights), the surrender for transfer of any of the Common Stock certificates outstanding as of April 6, 1998 or issued thereafter will also constitute the transfer of the Rights associated with the Common Stock represented by such certificate.

As soon as practicable following the Distribution Date, separate certificates evidencing the Rights ("Right Certificates") will  be mailed to holders of record of the Common Stock as of the close of business on the Distribution Date and such separate Right Certificates alone will evidence the Rights.  Subject to certain adjustments as may be required by the Rights Agreement, the Company will issue one Right with each new share of Common Stock issued until the Distribution Date so that all shares will have attached Rights.  No person shall be deemed to be an Acquiring Person on account of shares of Common Stock beneficially owned by

C-1

such person on March 23, 1998 unless thereafter they become the beneficial owner of any additional shares of Common Stock.

The Rights are not exercisable until the Distribution Date, and, if later, the expiration of the Company's right to redeem the Rights.  The Rights will expire on August 20, 2021, or, if earlier, the final adjournment of the Company's 2018 annual meeting of shareholders, if shareholder approval of the Rights Agreement, as amended by the First Amendment to the First Amended and Restated Rights Agreement dated August 20, 2018, has not been obtained, unless earlier redeemed or called for exchange by the Company as described below or their earlier expiration upon the consummation of certain transactions as described below.

The Preferred Stock will be nonredeemable and will be junior to any other class of preferred stock.  Each share of Preferred Stock will be entitled to receive when, as and if declared, a quarterly dividend equal to the greater of $1.00 or 100 times the per share value of any dividend (other than stock dividends) declared on the Common Stock since the immediately preceding quarterly dividend payment date.  In the event of liquidation, the holders of the Preferred Stock generally will be entitled to receive a liquidation payment in an amount equal to $100.00 per share of Preferred Stock plus all accrued and unpaid dividends thereon, and, after the holders of Common Stock have received a liquidation payment in an amount equal to $1.00 per share, holders of the Preferred Stock and the Common Stock shall receive their ratable and proportionate share of the remaining assets to be distributed, with the holders of Preferred Stock entitled to receive an aggregate per share amount equal to 100 times the aggregate amount to be distributed per share to holders of shares of Common Stock.  Each share of Preferred Stock will be entitled to 100 votes per share voting together with the Common Stock.  In the event of any merger, consolidation or other transaction in which the Common Stock is exchanged, each share of Preferred Stock will be entitled to receive 100 times the amount received per share of Common Stock.  The rights of the Preferred Stock as to dividends, voting and liquidation preferences are protected by anti-dilution provisions.

The Purchase Price payable, and the number of shares of the Preferred Stock or other securities or property issuable, upon exercise of the Rights are subject to adjustment from time to time to prevent dilution (i) in the event of a stock dividend on, or a subdivision, combination or reclassification of the Preferred Stock; (ii) upon the grant to holders of the Preferred Stock of certain rights or warrants to subscribe for shares of the Preferred Stock or convertible securities at less than the current market price of the Preferred Stock; or (iii) upon the distribution to holders of the Preferred Stock of evidences of indebtedness or assets (excluding regular periodic cash dividends out of earnings or retained earnings at a rate not in excess of 125% of the rate of the last cash dividend theretofore paid or a dividend paid in the Preferred Stock) or of subscription rights or warrants (other than those referred to above).  With certain exceptions, no adjustment in the Purchase Price will be required until cumulative adjustments require an adjustment of at least 1% in such Purchase Price.

Prior to a Triggering Event, fractional shares of the Preferred Stock will not be issued (other than fractions which are integral multiples of one one-hundredths of a share of Preferred Stock) and, in lieu thereof, an adjustment in cash will be made equal to the same fraction of the current market value of one one-hundredth of a share of Preferred Stock.  Following the occurrence of a Triggering Event, the Company shall not be required to issue fractions of shares

C-2

of Common Stock and, in lieu thereof, an adjustment in cash will be made equal to the same fraction of the current market value of one share of Common Stock.

In the event that (i) the Company were the surviving corporation in a merger or other combination with an Acquiring Person or affiliated or associated persons of an Acquiring Person and its Common Stock were not changed or exchanged; or (ii) an Acquiring Person engages in one of a number of self-dealing transactions specified in the Rights Agreement; or (iii) in certain circumstances, an Acquiring Person becomes the beneficial owner of 20% or more of the outstanding shares of Common Stock (except pursuant to a tender or exchange offer for all outstanding shares at a price and on terms determined by a majority of the Board of Directors, prior to the consummation of the offer, after receiving advice from an investment banking firm selected by a majority of the Board of Directors, to be a price that is fair to shareholders and in the best interests of the Company and its shareholders (a "Permitted Offer")), or (iv) during such time as there is an Acquiring Person, there shall occur certain failures to pay, or reductions in, dividends on outstanding common or preferred stock of the Company or a recapitalization of the Company which has the effect of increasing the Acquiring Person's proportionate share of the outstanding Common Stock by more than 1%, then proper provision shall be made so that each holder of a Right, other than Rights that were or are beneficially owned by the Acquiring Person (which will thereafter be void), shall thereafter have the right to receive upon exercise that number of shares of the Common Stock (or, in certain circumstances, a combination of cash, other property, Preferred Stock, Common Stock and/or other securities) having a market value of two times the exercise price of the Right.

Following the Distribution Date, in the event (i) that the Company were acquired in a merger or other business combination transaction in connection with which the Company is not the continuing or surviving corporation or in which all or a part of the Common Stock shall be changed into or exchanged for stock or other securities of any other Person or cash or any other property (other than certain mergers and combinations with an Acquiring Person who becomes such in a Permitted Offer if the price per share of Common Stock offered in such transaction is no less than the price per share of Common Stock paid to all holders in the Permitted Offer tender or exchange offer and the form of consideration being offered in such transaction is the same as the form of consideration paid in the Permitted Offer tender or exchange offer (a "Permitted Combination")); or (ii) that 50% or more of the Company's assets or earning power were sold, then proper provision shall be made so that each holder of a Right, other than Rights that were or are beneficially owned by the Acquiring Person (which will thereafter be void), shall thereafter have the right to receive, upon the exercise thereof at the then current exercise price of the Right, that number of shares of common stock of the Acquiring Person which at the time of such transaction would have a market value of two times the exercise price of the Right.  Upon the consummation of a Permitted Combination, all rights shall expire.  Each of the events described in this paragraph constitutes a "Triggering Event" under the Rights Agreement.

At any time after any Person becomes an Acquiring Person but prior to the time such Acquiring Person has acquired 50% or more of the outstanding Common Stock, the Board may cause shareholders to exchange all or part of their Rights for shares of Common Stock or Preferred Stock at a ratio of one share of Common Stock or one one-hundredth of a share of Preferred Stock per Right, subject to adjustment.  As soon as the Board has determined to make such exchange, the Rights may no longer be exercised.

C-3

At any time prior to a person or group of affiliated or associated persons becoming an Acquiring Person (or, if pursuant to a Permitted Offer (as defined below) such later date as fixed by the Board of Directors), the Board of Directors of the Company may redeem the Rights in whole, but not in part, at a price of $.001 per Right (the "Redemption Price").  Thereafter, the Company's right of redemption may be reinstated, prior to a Triggering Event, (i) if an Acquiring Person reduces his beneficial ownership to less than 20% of the outstanding shares of Common Stock in a transaction or series of transactions not involving the Company; and (ii) there are no other Persons, immediately following the event described in clause (i), who are Acquiring Persons.  Additionally, the Board of Directors may at any time prior to the occurrence of a Triggering Event, redeem the then outstanding Rights in whole, but not in part, at the Redemption Price, if such redemption is in connection with the consummation of a merger or other business combination involving the Company but not involving an Acquiring Person or its Affiliates or Associates which is determined to be in the best interests of the Company and its shareholders by the Board of Directors.

However, in the event the Company receives a Qualified Offer (as defined below), the Rights may be redeemed by way of shareholder action taken at a special meeting of shareholders called for the purpose of voting on a resolution accepting the Qualified Offer and authorizing the redemption of the Rights pursuant to the provisions of the Agreement. The special meeting must be held within 90 business days after the Company receives a request from shareholders to hold such a meeting.  The request from shareholders must be received by the Company not earlier than 60 business days and not later than 80 business days following the commencement of the Qualified Offer and must be executed by holders of not less than 10% of the outstanding Common Stock (excluding the Acquiring Person and its affiliates and associates).  If a resolution to redeem the Rights is approved by holders of a majority of the outstanding Common Stock (excluding the Acquiring Person and its affiliates and associates) at the special meeting (or if the special meeting is not held on or before the 90th business day after receipt of the request for a meeting or such later date at which an acquisition agreement approved by the Board is voted on by shareholders), it will become effective immediately prior to the consummation of any Qualified Offer consummated within 60 days after the earlier of the special meeting or the 90th business day after receipt of a request for a special meeting of shareholders. A "Qualified Offer" is a tender offer for all outstanding Common Stock not already beneficially owned by the person making the offer that meets all of the following conditions:

C-4

C-5

Immediately upon the action of the Board of Directors of the Company electing to redeem the Rights, the Company shall make announcement thereof, and upon such election, the right to exercise the Rights will terminate and the only right of the holders of Rights will be to receive the Redemption Price.  At the effective time of a redemption in connection with the calling of a special meeting of shareholders in connection with a Qualified Offer, the right to exercise the Rights shall terminate and the only right of holders of the Rights will be to receive the Redemption Price.

Until a Right is exercised, the holder thereof, as such, will have no rights as a shareholder of the Company, including, without limitation, the right to vote or to receive dividends.

The Rights Agreement may be amended without shareholder approval prior to the Distribution Date at the Board of Directors' discretion.  After the Distribution Date, the Board of Directors generally may amend the Rights Agreement without the consent of the Rights holders to cure any ambiguity, correct defects or inconsistencies, shorten or lengthen time periods or supplement or change any other provision which shall not adversely affect the Rights holders; provided that the lengthening of any time period is for the purpose of protecting, enhancing or clarifying the rights of, and/or for the benefit of the holders of the Rights (other than the Acquiring Person and its affiliated and associated persons).  However, if the Rights are not then redeemable, the Board may not lengthen a time period relating to when the Rights may be redeemed.

A copy of the Rights Agreement, as amended, has been filed with the Securities and Exchange Commission as an Exhibit to the report on Form 8-K filed on August 20, 2018, and as an Exhibit to Form 8-A/A, dated August 20, 2018.  A copy of the Rights Agreement is available free of charge from the Company.  This summary description of the Rights does not purport to be complete and is qualified in its entirety by reference to the Rights Agreement, which is hereby incorporated herein by reference.
