    THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A RIGHT OF FIRST REFUSAL OPTION IN FAVOR OF THE CORPORATION AND/OR ITS ASSIGNEE(S), AS PROVIDED IN THE BYLAWS OF THE CORPORATION.

    

    

    THE SALE, PLEDGE, HYPOTHECATION OR TRANSFER OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO THE TERMS AND CONDITIONS OF A STOCKHOLDERS AGREEMENT AMONG THE CORPORATION AND ITS
      STOCKHOLDERS.  COPIES OF SUCH AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE CORPORATION.

    

    

    (b)          During the term of this Agreement, the Company shall not remove, and shall not permit to be removed (upon registration of transfer, re-issuance of
      otherwise), the Legend from any such certificate and shall place or cause to be placed such legend on any new certificate issued to represent Shares theretofore represented by a certificate bearing such legend.  The Stockholders agree that the
      Company shall instruct its transfer agent to impose transfer restrictions on the shares represented by certificates bearing the Legend to enforce the provisions of this Agreement and the Company agrees to promptly do so.

    

    

    (c)          In the event of any issuance of Shares after the Effective Date to any of the Stockholders (including, without limitation, in connection with any
      stock split, stock dividend, recapitalization, reorganization, or the like), such Shares shall become subject to this Agreement and shall be endorsed with the Legend.

    

    

    (d)          The foregoing legend shall be removed only upon termination of this Agreement.

    

    

    3.          INTENTIONALLY OMMITTED.

    

    

    4.          VOTING.

    

    

    4.1          General.  The Stockholders each agree to hold all
      their Shares (including, without limitation, all shares of the Common Stock now held or issuable upon conversion of any convertible Preferred Stock) subject to, and to vote their Shares in accordance with, the provisions of this Section 4.

    

    

    
      5

      
        


    

    4.2          Manner of Voting.  The voting of shares pursuant to
      this Agreement may be effected in person, by proxy, by written consent, or in any other manner permitted by applicable law.  All of the Stockholders agree to execute any written consents required to perform the obligations of this Agreement, and the
      Company agrees at the request of any party entitled to designate Directors (as defined below) to call a special meeting of the Stockholders for the purpose of electing Directors as provided herein.

    

    

    4.3          Board Size.  At all regular or special meetings of the stockholders of the
      Company following the Effective Date, each of the Stockholders shall vote all of their respective Shares held by them (or the holders thereof shall consent pursuant to an action by written consent of the holders of capital stock of the Company) so as
      to ensure that the size and composition of the Board is as directed by the then current Board (each a “Director” and, collectively, the “Directors”).  The initial size of the Board shall be three (3) Directors and may be increased to up to five (5) Directors by the then current Board.

    

    

    4.4          Election of Directors.  On all matters relating to the election of the Directors, the Stockholders agree to vote all Shares held by them (or the holders thereof shall consent pursuant to an action by written consent of the holders of
      capital stock of the Company) so as to elect initially the following Directors: Alan Meyer and Mina Sooch; and thereafter the nominees recommended by the then current Board.

    

    

    4.5          Failure to Designate a Director.  In the
      absence of any designation from the Persons or groups with the right to designate a Director as specified above, the Director previously designated by them and then serving shall be reelected if still eligible to serve as provided herein.

    

    

    4.6          No Liability for Election of Designated Director.  No party, nor any Affiliate
      of any such party, shall have any liability as a result of nominating or designating a person for election as a Director for any act or omission by such person in his or her capacity as a Director, nor shall any party have any liability as a result
      of voting for any such person in accordance with the provisions of this Agreement.  None of the parties hereto and no officer, director, stockholder, partner, employee or agent of any party makes any representation or warranty as to the fitness or
      competence of the nominee of any party hereunder to serve on the Board by virtue of such party’s execution of this Agreement or by the act of such party in voting for such nominee pursuant to this Agreement.

    

    

    4.7          Drag-Along Right.

    

    

    (a)          In the event that the Board and those Stockholders holding a majority in interest of the outstanding capital stock of the Company vote to approve
      a Change in Control, then each Stockholder hereby agrees:

    

    

    (i)          if such Change in Control requires stockholder approval, with respect to all Shares that such Stockholder owns or over which such Stockholder
      otherwise exercises voting power, to vote (i) all such Shares in favor of, and adopt, such Change in Control (together with any related amendment to the Certificate required in order to implement such Change in Control), and (ii) in opposition to any
      and all other proposals that could reasonably be expected to delay or impair the ability of the Company to consummate such Change in Control;

    

    

    
      6

      
        


    

    (ii)          if such Change in Control is to be effected by sale of Company capital stock to a third party (a “Stock Sale”), to sell the same proportion of shares of capital stock of the Company beneficially held by such Stockholder as is being sold by all other holders of Company capital stock and, except as permitted in Section 4.7(b),
      on the same terms and conditions as holders of the same class or series of Company capital stock are so selling;

    

    

    (iii)          to execute and deliver all related documentation and take such other action in support of the Change in Control as shall reasonably be
      requested by the Company in order to carry out the terms and provisions of this Section 4.7, including, without limitation, executing and delivering instruments of conveyance and transfer, and any purchase agreement, merger agreement,
      indemnity agreement, escrow agreement, exchange agreement, consent, waiver, governmental filing, share certificates duly endorsed for transfer (free and clear of impermissible liens, claims and encumbrances) and any similar or related documents;

    

    

    (iv)          not to deposit, and to cause their Affiliates not to deposit, except as provided in this Agreement, any Shares owned by such Stockholder or its
      Affiliate in a voting trust or subject any Shares to any arrangement or agreement with respect to the voting of such Shares, unless specifically requested to do so by the acquirer in connection with the Change in Control;

    

    

    (v)          not to assert or exercise any dissenters’ rights or rights of appraisal under applicable law at any time with respect to such Change in Control;
      and

    

    

    (vi)          if the consideration to be paid in exchange for the Shares in any Change in Control includes any securities and due receipt thereof by any
      Stockholder would require under applicable law (A) the registration or qualification of such securities or of any person as a broker or dealer or agent with respect to such securities, or (B) the provision to any Stockholder of any information other
      than such information as a prudent issuer would generally furnish in an offering made solely to “accredited investors” as defined in Regulation D, as promulgated under the Securities Act, the Company may cause to be paid to any such Stockholder in
      lieu thereof, against surrender of the Shares which would have otherwise been sold by such Stockholder, an amount in cash equal to the fair value (as determined in good faith by the Company) of the securities which such Stockholder would otherwise
      receive as of the date of the issuance of such securities in exchange for such Stockholder’s Shares.

    

    

    (b)          Notwithstanding the foregoing Section 4.7(a), no Stockholder will be required to comply with such section in connection with any proposed
      Change in Control unless:

    

    

    (i)          any representations and warranties to be made by such Stockholder in connection with such proposed Change in Control are limited to
      representations and warranties related to authority, ownership and the ability to convey title to such Stockholder’s Shares, including, without limitation, representations and warranties that (A) the Stockholder holds all right, title and interest in
      and to the Shares such Stockholder purports to hold, free and clear of all liens and encumbrances, (B) the obligations of the Stockholder in connection with the proposed Change in Control have been duly authorized, if applicable, (C) the documents to
      be entered into by the Stockholder have been duly executed by the Stockholder and delivered to the acquirer and are enforceable against the Stockholder in accordance with their respective terms, and (D) neither the execution and delivery of documents
      to be entered into in connection with such proposed Change in Control, nor the performance of the Stockholder’s obligations thereunder, will cause a breach or violation of the terms of any agreement, law or judgment, order or decree of any court or
      governmental agency;

    

    

    
      7

      
        


    

    (ii)          the Stockholder shall not be liable for the inaccuracy of any representation or warranty made by any other Person in connection with such
      proposed Change in Control, other than the Company (except to the extent that funds may be paid in proportion to the amount of consideration to be received by such Stockholder out of an escrow established to cover breach of representations,
      warranties and covenants of the Company as well as breach by any Stockholder of any of identical representations, warranties and covenants provided by all Stockholders);

    

    

    (iii)          the liability for indemnification, if any, of such Stockholder in such proposed Change in Control and for the inaccuracy of any representations
      and warranties made by the Company in connection with such proposed Change in Control, is several and not joint with any other Person (except to the extent that funds may be paid out of an escrow established to cover breach of representations,
      warranties and covenants of the Company as well as breach by any Stockholder of any of identical representations, warranties and covenants provided by all Stockholders), and is pro rata in proportion to the amount of consideration paid to such
      Stockholder in connection with such proposed Change in Control (in accordance with the provisions of the Certificate);

    

    

    (iv)          the Stockholder’s liability shall be limited to such Stockholder’s applicable share (determined based on the respective proceeds payable to each
      Stockholder in connection with such proposed Change in Control in accordance with the provisions of the Certificate) of a negotiated aggregate indemnification amount that applies equally to all Stockholders but that in no event exceeds the amount of
      consideration otherwise payable to such Stockholder in connection with such proposed Change in Control, except with respect to claims related to fraud, intentional misrepresentation or willful misconduct by such Stockholder, the liability for which
      need not be limited as to such Stockholder;

    

    

    (v)          upon the consummation of such proposed Change in Control, (A) each holder of each class or series of the Company’s capital stock will receive the
      same form of consideration for their shares of such class or series as is received by other holders in respect of their shares of such same class or series of stock, (B) each holder of a series of Preferred Stock will receive the same amount of
      consideration per share of such series of Preferred Stock as is received by other holders in respect of their shares of Preferred Stock of such same series, (C) each holder of the Common Stock will receive the same amount of consideration per share
      of such Common Stock as is received by other holders in respect of their shares of the Common Stock, and (D) the aggregate consideration receivable by all holders of the Preferred Stock and Common Stock shall be allocated among the holders of the
      Preferred Stock and Common Stock on the basis of the relative liquidation preferences, if any, set forth in the Certificate in connection with a liquidation or a Change in Control, as applicable; and

    

    

    
      8

      
        


    

    (vi)          subject to the foregoing subsection (v), requiring the same form of consideration to be available to the holders of any single class or series
      of capital stock, if any holders of any capital stock of the Company are given an option as to the form and amount of consideration to be received as a result of such proposed Change in Control, all holders of such capital stock will be given the
      same option.

    

    

    4.8          Irrevocable Proxy.  Each Stockholder hereby constitutes and appoints the
      Secretary and each Assistant Secretary of the Company, with full power of substitution, as the proxies of the party with respect to the matters set forth herein, including without limitation, election of the Directors in accordance with Section
        4.4 and the drag-along provisions of Section 4.7, and hereby authorizes each of them to represent and to vote, if and only if the party (a) fails to vote or (b) attempts to vote (whether by proxy, in person or by written consent), in a
      manner which is inconsistent with the terms of this Agreement, all of such party’s Shares in accordance with such sections.  The proxy granted pursuant to the immediately preceding sentence is given in consideration of the agreements and covenants of
      the Company and the parties in connection with the transactions contemplated by this Agreement and, as such, is coupled with an interest and shall be irrevocable unless and until this Agreement terminates or expires pursuant to Section 6.5. 
      Each Stockholder hereby revokes any and all previous proxies with respect to the Shares and shall not hereafter, unless and until this Agreement terminates or expires pursuant to Section 6.5, purport to grant any other proxy or power of
      attorney with respect to any of the Shares, deposit any of the Shares into a voting trust or enter into any agreement (other than this Agreement), arrangement or understanding with any person, directly or indirectly, to vote, grant any proxy or give
      instructions with respect to the voting of any of the Shares, in each case, with respect to any of the matters set forth herein.

    

    

    4.9          Additional Shares. 

    

    

    (a)          In the event that after the Effective Date, the Company enters into an agreement with any Person to issue shares of capital stock to such Person,
      following which such Person shall hold Shares, then the Company shall cause such Person, as a condition precedent to entering into such agreement, to become a party to this Agreement by executing an Adoption Agreement in the form attached to this
      Agreement as Exhibit 1 (the “Adoption Agreement”), agreeing to be bound by and subject to the terms of this Agreement as a Stockholder
      and thereafter such person shall be deemed a Stockholder for all purposes under this Agreement.

    

    

    (b)          In the event that subsequent to the Effective Date any shares or other securities are issued on, or in exchange for, any of a Stockholder’s Shares
      by reason of any stock dividend, stock split, combination of shares, reclassification or the like, such shares or securities shall be deemed to be Shares for purposes of this Agreement.

    

    

    5.          MARKET STAND-OFF.

    

    

    5.1          Market Stand-Off.    Each Stockholder agrees not to
      sell, dispose of, transfer, make any short sale of, or grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, any Equity Securities, during the one hundred and eighty (180) day
      period following the effective date of the Company’s first firm commitment underwritten public offering of its Common Stock (or such shorter or longer period as the underwriters or the Company shall request in order to facilitate compliance with
      FINRA Rule 2711 or NYSE Member Rule 472 or any successor or similar rule or regulation) (the “Lock Up Period”); provided, however, that nothing contained in this Section 5 shall
      prevent the exercise of any repurchase rights of the Company for such Equity Securities during the Lock Up Period.  Each Stockholder agrees to execute and deliver such other agreements as may be reasonably requested by the Company and/or the managing
      underwriters that are consistent with the foregoing or that are necessary to give further effect to the foregoing provision.  In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to a
      Stockholder’s Equity Securities until the end of such period. The underwriters of the Company’s stock are intended third party beneficiaries of this Section 5 and shall have the right, power and authority to enforce the provisions hereof as
      though they were a party to this Agreement.

    

    

    
      9

      
        


    

    6.          MISCELLANEOUS.

    

    

    6.1          Ownership.  Each Stockholder represents and warrants
      to the other Stockholders and the Company that:

    

    

    (a)          such Stockholder now owns the Stockholder’s Shares, free and clear of liens or encumbrances, and has not, prior to or on the Effective Date,
      executed or delivered any proxy or entered into any other voting agreement or similar arrangement other than one which has expired or terminated prior to the Effective Date;

    

    

    (b)          such Stockholder has full power and capacity to execute, deliver and perform this Agreement, which has been duly executed and delivered by, and
      evidences the valid and binding obligation of, such Stockholder enforceable in accordance with its terms; and

    

    

    (c)          such Stockholder is, or, at the time of purchase of the interests in the Merging LLC, was, an “accredited investor” within the meaning of Rule 501
      of Regulation D, as promulgated under the Securities Act or is an executive officer or director of the Company and in such capacity is sufficiently familiar with the affairs of the Company to evaluate the risks and merits of owning shares of the
      Company.

    

    

    6.2          Further Action.  If and whenever a Stockholder’s
      Shares are sold, the Stockholder or the personal representative of the Stockholder shall do all things and execute and deliver all documents and make all transfers, and cause any transferee of the Stockholder Shares to do all things and execute and
      deliver all documents, as may be necessary to consummate such sale consistent with this Agreement.

    

    

    6.3          Specific Performance.  The parties hereto hereby
      declare that it is impossible to measure in money the damages which will accrue to a party hereto or to their heirs, personal representatives, or assigns by reason of a failure to perform any of the obligations under this Agreement and agree that the
      terms of this Agreement shall be specifically enforceable.  If any party hereto or his heirs, personal representatives, or assigns institutes any action or proceeding to specifically enforce the provisions hereof, any person against whom such action
      or proceeding is brought hereby waives the claim or defense therein that such party or such personal representative has an adequate remedy at law, and such person shall not offer in any such action or proceeding the claim or defense that such remedy
      at law exists.

    

    

    
      10

      
        


    

    6.4          Remedies Cumulative.  All remedies, either under this Agreement or by law or
      otherwise afforded to any party, shall be cumulative and not alternative.

    

    

    6.5          Termination.  Except as otherwise provided in this Agreement, and specifically
      except for the obligations set forth in Section 5 hereof which shall survive any termination of this pursuant to subsections (a) and (b) below, this Agreement shall continue in full force and effect from the Effective Date through the earliest of the
      following dates, on which date it shall terminate in its entirety:

    

    

    (a)          the date of the closing of the Initial Offering;

    

    

    (b)          the date of the closing of a Change in Control; or

    

    

    (c)          the date upon which the parties hereto terminate this Agreement by written consent of the Company and the holders of at least a majority of the
      outstanding shares of capital stock of the Company subject to this Agreement.

    

    

    6.6          Governing Law; Venue; Waiver of Jury Trial.  This Agreement shall be governed
      by and construed in accordance with the laws of the State of Delaware, without regard to its principles of conflicts of laws.  Each of the parties hereto irrevocably submits to the exclusive jurisdiction of the courts of the State of Michigan and any
      United States District Court in the State of Michigan for the purpose of any suit, action, proceeding or judgment relating to or arising out of this Agreement and the transactions contemplated hereby.  Service of process in connection with any such
      suit, action or proceeding may be served on each party hereto anywhere in the world by the same methods as are specified for the giving of notices under this Agreement.  Each of the parties hereto irrevocably consents to the jurisdiction of any such
      court in any such suit, action or proceeding and to the laying of venue in such court.  Each party hereto irrevocably waives any objection to the laying of venue of any such suit, action or proceeding brought in such courts and irrevocably waives any
      claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum.  EACH OF THE PARTIES HERETO WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS AGREEMENT AND
      REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER.

    

    

    6.7          Successors and Assigns.  Except as otherwise expressly provided herein, the
      provisions hereof shall inure to the benefit of, and be binding upon, the successors, assigns, heirs, executors, and administrators of the parties hereto and shall inure to the benefit of and be enforceable by each person who shall be a holder of
      Shares from time to time and become a party to this Agreement.

    

    

    6.8          Transfers.  As


      a condition precedent to the Company’s recognizing any transferee or assignee of any Shares to any Person, such Person shall agree in writing to be subject to each of the terms of this Agreement by executing and delivering an Adoption Agreement. 
      Upon the execution and delivery of an Adoption Agreement by any transferee, such transferee shall be deemed to be a party hereto as if such transferee were the transferor and such transferee’s signature appeared on the signature pages of this
      Agreement and shall be deemed to be a Stockholder.  The Company shall not permit the transfer of the Shares subject to this Agreement on its books or issue a new certificate representing any such Shares unless and until such transferee shall have
      complied with the terms of Section 2.1.  Each certificate representing the Shares subject to this Agreement if issued on or after the Effective Date shall be endorsed by the Company with the legend set forth in Section 2.5.

    

    

    
      11

      
        


    

    6.9          Entire Agreement.  This Agreement, the Exhibits and Schedules hereto and the
      other documents delivered pursuant thereto constitute the full and entire understanding and agreement between the parties with regard to the subjects hereof and no party shall be liable or bound to any other in any manner by any representations,
      warranties, covenants and agreements except as specifically set forth herein and therein; provided, however, that in the event of a conflict between the terms of this Agreement and any of those certain Restricted Stock Purchase Agreements entered
      into by and between the Company and certain of the Stockholders (the “RSAs”),

      the terms of the RSAs shall control.

    

    

    6.10          Prior Agreement.  Those Stockholders party to the Ocularis LLC Agreement, representing a majority
      in interest of the ownership of the Merging LLC, desire that this Agreement shall effectively amend and restate the Ocularis LLC Agreement, and that following the effective time of the Merger, each Stockholder who was a member of the Merging LLC
      shall be deemed to be party to this Agreement, in so far as such Stockholder would be bound by the provisions of the Ocularis LLC Agreement prior to the effective time of the Merger.

    

    

    6.11          Severability.  In the event one or more of the provisions of this Agreement
      should, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality, or unenforceability shall not affect any other provisions of this Agreement, and this Agreement shall be construed as if such
      invalid, illegal or unenforceable provision had never been contained herein.

    

    

    6.12          Amendment and Waiver.

    

    

    (a)          Except as otherwise expressly provided herein, this Agreement may be amended or modified only upon the written consent of the Company and the
      holders of at least a majority of the outstanding shares of capital stock of the Company subject to this Agreement. Any such amendment or modification effected in accordance with this Section 6.11(a) shall be binding on all stockholders of
      the Company, even if they do not execute such consent.

    

    

    (b)          Any party hereto may waive compliance with any agreements, covenants or conditions for the benefit of such party contained herein.  Any agreement
      on the part of a party hereto to any such waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party.

    

    

    (c)          Except as otherwise expressly provided, the obligations of the Company and the rights of the Stockholders under this Agreement may be waived with
      respect to all stockholders of the Company (either generally or in a particular instance and either retroactively or prospectively) only with the written consent of the Company and the holders of at least a majority of the outstanding shares of
      capital stock of the Company subject to this Agreement.  Any such waiver effected in accordance with this Section 6.11(c) shall be binding on all stockholders of the Company, even if they do not execute such consent.  Each Stockholder
      acknowledges that by the operation of this Section 6.11(c), holders of at least a majority of the outstanding capital stock of the Company subject to this Agreement will have the right and power to diminish or eliminate all rights of any
      Stockholder under this Agreement.

    

    

    
      12

      
        


    

    (d)          For the purposes of determining the Stockholders entitled to vote or exercise any rights hereunder, the Company shall be entitled to rely solely
      on the list of record holders of its stock as maintained by or on behalf of the Company.

    

    

    6.13          Delays or Omissions.  It is agreed that no delay or omission to exercise any
      right, power, or remedy accruing to any Stockholder, upon any breach, default or noncompliance of the Company under this Agreement shall impair any such right, power, or remedy, nor shall it be construed to be a waiver of any such breach, default or
      noncompliance, or any acquiescence therein, or of any similar breach, default or noncompliance thereafter occurring.  It is further agreed that any waiver, permit, consent, or approval of any kind or character on any Stockholder’s part of any breach,
      default or noncompliance under the Agreement or any waiver on such Stockholder’s part of any provisions or conditions of this Agreement must be in writing and shall be effective only to the extent specifically set forth in such writing.  All
      remedies, either under this Agreement, by law, or otherwise afforded to the Stockholders, shall be cumulative and not alternative.

    

    

    6.14          Notices.  All notices required or permitted hereunder shall be in writing and
      shall be deemed effectively given: (a) upon personal delivery to the party to be notified; (b) when sent by confirmed electronic mail or facsimile if sent during normal business hours of the recipient; if not, then on the next business day; (c) five
