Capitalized terms used but not otherwise defined herein shall have the meanings given to such terms in the Merger Agreement (as defined below).

WHEREAS, in order to induce Parent, Geranium Merger Sub I, Inc., a Michigan corporation and a direct, wholly owned Subsidiary of Parent (“Merger Sub Inc.”), and Geranium Merger Sub II, LLC, a Michigan limited liability company and a direct, wholly owned Subsidiary of Parent (“Merger Sub LLC”), to enter into an Agreement and Plan of Merger, dated as of the date hereof (the “Merger Agreement”), with the Company, Parent has requested each Shareholder, and each Shareholder has agreed, to enter into this Agreement with respect to the number of shares of Company Class A Common Stock and Company Class B Common Stock (collectively, the “Shares”) that such Shareholder beneficially owns as of the date hereof and are set forth next to such Shareholder’s name on Schedule A hereto (together with such additional Shares or voting securities of which such Shareholder acquires record or beneficial ownership after the date hereof, such Shareholder’s “Subject Shares”).

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, hereby agree as follows:

Article 1
Grant of Proxy; Voting Agreement

Section 1.01.    Voting Agreement. Beginning on the date hereof until the Expiration Date, each Shareholder hereby irrevocably and unconditionally agrees that at any meeting of the shareholders of the Company, however called, and at any adjournment thereof, at which the Merger Agreement (or any amended version thereof) or the transactions contemplated thereby are submitted for the consideration and vote of the shareholders of the Company, and in connection with any written consent of the shareholders of the Company, or in any other circumstance in which the vote, consent or other approval of the shareholders of the Company is sought, each Shareholder shall, in each case to the fullest extent that its Subject Shares are entitled to vote thereon or consent thereto, (a) appear at such meeting or otherwise cause its Subject Shares to be counted as present thereat for purposes of calculating a quorum, and (b) vote (or cause to be voted), in person or by proxy, or, if applicable, deliver (or cause to be delivered) a written consent with respect to all Subject Shares that such Shareholder is entitled to vote at the time of any vote or action by written consent (i) in favor of the approval and adoption (as applicable) of the Merger Agreement and the transactions contemplated thereby, including the First Merger, (ii) in favor of any proposal to adjourn a meeting of the shareholders of the Company to solicit

additional proxies in favor of the approval and adoption (as applicable) of the Merger Agreement and the transactions contemplated thereby, including the First Merger, and (iii) against any (1) Company Acquisition Proposal, (2) reorganization, recapitalization, liquidation or winding-up of the Company or any other extraordinary transaction involving the Company, (3) action or agreement the consummation of which would reasonably be expected to, individually or in the aggregate, impair in any material respect the ability of the Company to perform its obligations under the Merger Agreement or consummate the Mergers, or prevent or materially delay the consummation of any of the Mergers and the other transactions contemplated by the Merger Agreement and (4) any action or agreement that would reasonably be expected to result in a material breach or violation of any covenant, representation or warranty or any other obligation of such Shareholder contained in this Agreement. Nothing contained in this Agreement shall require any Shareholder (or shall entitle any proxy of any Shareholder) to convert, exercise or exchange any shares of Company Class B Common Stock in order to obtain any shares of Company Class A Common Stock.

Section 1.02.    Irrevocable Proxy. Each Shareholder hereby revokes any and all previous proxies granted with respect to its Subject Shares (and such Shareholder hereby represents that any such prior proxy is revocable), other than proxies granted solely with respect to Routine Matters (as defined below). By entering into this Agreement, such Shareholder hereby grants a proxy appointing Parent as such Shareholder’s attorney-in-fact and proxy, with full power of substitution, for and in such Shareholder’s name with respect to the Subject Shares, effective as of the date hereof and continuing until the Expiration Date, to vote, express consent or dissent, or otherwise to utilize such voting power solely as contemplated by ‎Section 1.01 above; provided that Parent shall provide at least twenty-four (24) hours’ notice prior to exercising the proxy granted by such Shareholder under this Section ‎1.02 to the extent Parent intends to exercise such proxy within five (5) Business Days of the mailing of the Joint Proxy Statement. The proxy granted by such Shareholder pursuant to this Section ‎1.02 is irrevocable and is granted in consideration of Parent entering into this Agreement and the Merger Agreement and incurring certain related fees and expenses. The proxy granted by such Shareholder shall automatically be revoked upon the Expiration Date. Each Shareholder hereby ratifies and confirms all actions that the proxy appointed hereunder may lawfully do or cause to be done in accordance with this Section ‎1.02. Each Shareholder intends this proxy to be irrevocable and unconditional during the term of this Agreement and coupled with an interest and will take such further action or execute such other instruments as may be reasonably necessary to effect the intent of this proxy. Each Shareholder hereby agrees not to grant any proxy or enter into any voting trust or other agreement or arrangement with respect to the voting of any Subject Shares during the term of this Agreement (except for a Permitted Transfer), other than the granting of proxies to vote Subject Shares with respect to the election of directors, ratification of the appointment of the Company’s auditors at the Company’s annual meeting or special meeting of shareholders, and other routine matters at the Company’s annual meeting or any special meeting, in either case, solely to the extent such matters are not (i) inconsistent with the obligations contemplated by the Merger Agreement or this Agreement or (ii) related to the transactions contemplated by the Merger Agreement or this Agreement (collectively, “Routine Matters”). Any attempt by such Shareholder to grant a proxy, vote, consent or express dissent with respect to (or

otherwise to utilize the voting power of) its Subject Shares in a manner inconsistent with the proxy granted pursuant to this Section ‎1.02 shall be null and void ab initio.

The execution, delivery and performance by such Shareholder of this Agreement and the consummation by such Shareholder of the transactions contemplated hereby are within the organizational or individual powers of such Shareholder and have been duly authorized by all necessary action on the part of such Shareholder. This Agreement constitutes a legal, valid and binding Agreement of such Shareholder, enforceable against such Shareholder in accordance with its terms, subject to applicable bankruptcy, insolvency (including all Laws related to fraudulent transfers), reorganization, moratorium or other similar Laws, now or hereafter in effect, affecting creditors’ rights and remedies generally and the remedies of specific performance and injunctive and other forms of equitable relief that may be subject to equitable defenses and to the discretion of the court before which any Proceeding therefor may be brought (the “Enforceability Exceptions”).

Other than as provided in the Merger Agreement and except for any filings by such Shareholder with the SEC, the execution, delivery and performance by such Shareholder of this Agreement do not require any action by or in respect of, or any notice, report or other filing by such Shareholder with or to, or any consent, registration, approval, permit or authorization from, any Governmental Authority, other than any actions or filings the absence of which would not reasonably be expected to, individually or in the aggregate, prevent or materially delay or impair or otherwise adversely impact such Shareholder’s ability to perform its obligations hereunder.

Except for this Agreement, such Shareholder represents that such Shareholder has not (i) taken any action that would or would reasonably be expected to (A) violate or conflict with such Shareholder’s covenants and obligations under this Agreement, (B) make any representation or warranty of such Shareholder set forth in this Agreement untrue or incorrect or (C) have the effect of preventing or disabling such Shareholder from performing any of its obligations under this Agreement or (ii) granted any proxies or powers of attorney, or any other authorization or consent with respect to any of the Subject Shares with respect to the matters set forth in Section ‎1.01.

Section 2.08.    Finder’s Fees.

Article 4
Covenants of Shareholders

Each Shareholder hereby covenants and agrees that:

A “Permitted Transfer” shall mean a Transfer to a Permitted Person so long as, in the case of subclause (A) and (B)(1) thereof, such Transfer is done for estate planning purposes, would not reasonably be expected to, individually or in the aggregate, prevent or materially delay or impair or otherwise adversely impact in any material respect such Shareholder’s (and transferee Shareholder’s) ability to perform its obligations hereunder and the transferee of such Subject Shares evidences in a writing in form and substance reasonably satisfactory to Parent such transferee’s agreement to be bound by and subject to the terms and provisions hereof to the same effect as the transferring Shareholder, and upon such transfer shall be deemed a Shareholder hereunder. Such Shareholder hereby agrees that this Agreement and the obligations hereunder shall attach to such Shareholder’s Subject Shares and shall be binding upon any Person to which legal or beneficial ownership shall pass, whether by operation of law or otherwise, including its successors or permitted assigns, and if any involuntary Transfer of any of such Shareholder’s Subject Shares shall occur (including a sale by such Shareholder’s trustee in any bankruptcy, or a sale to a purchaser at any creditor’s or court sale), the transferee (which term, as used herein, shall include any and all transferees and subsequent transferees of the initial transferee) shall take and hold such Shareholder’s Subject Shares subject to all of the restrictions, liabilities and rights under this Agreement as such Shareholder for all purposes hereunder. Each Shareholder hereby agrees not to request that the Company register the transfer of any certificate or uncertificated interest representing any or all of the Subject Shares and each Shareholder

authorizes the Company to impose stop orders to prevent the Transfer of any of such Shareholder’s Subject Shares in violation of this Agreement.

contemplated thereby, and such Shareholder hereby agrees to take all actions necessary to opt out of any class in any class action relating to the foregoing; provided that the foregoing shall not limit any actions taken by any Shareholder in response to any claims of the nature described in the foregoing clause (B) commenced against such Shareholder, its Affiliates or its Representatives; provided, further, that the foregoing shall not restrict any Shareholder from enforcing such Shareholder’s rights under this Agreement.

Each of the parties hereto hereby, with respect to any legal claim or Proceeding arising out of this Agreement or the transactions contemplated by this Agreement, (i) expressly and irrevocably submits, for itself and with respect to its property, generally and unconditionally, to the exclusive jurisdiction of the Delaware Court of Chancery and any appellate court therefrom within the State of Delaware (or, if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware), (ii) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such courts, (iii) agrees that it will not bring any claim or Proceeding relating to this Agreement or the transactions contemplated by this Agreement except in

such courts and (iv) irrevocably waives, to the fullest extent it may legally and effectively do so, and agrees not to assert, by way of motion or as a defense, counterclaim or otherwise, any objection which it may now or hereafter have to the laying of venue of any claim or Proceeding arising out of or relating to this Agreement. Notwithstanding the foregoing, each of the parties agrees that a final and non-appealable judgment in any Proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. Each party irrevocably consents to the service of process in any claim or Proceeding with respect to this Agreement and the transactions contemplated by this Agreement or for recognition and enforcement of any judgment in respect hereof brought by any other party hereto made by mailing copies thereof by registered or certified United States mail, postage prepaid, return receipt requested, to its address as specified in or pursuant to Section ‎5.04 and such service of process shall be sufficient to confer personal jurisdiction over such party in such claim or Proceeding and shall otherwise constitute effective and binding service in every respect.

Section 5.11.    WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY KNOWINGLY, INTENTIONALLY, AND VOLUNTARILY WAIVES TO THE FULLEST EXTENT PERMITTED BY LAW ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED IN CONTRACT, TORT OR OTHERWISE) BETWEEN THEM ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE ACTIONS OF ANY OTHER PARTY IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT HEREOF.

Section 5.12.    Counterparts This Agreement may be executed in multiple counterparts, all of which shall together be considered one and the same agreement. Delivery of an executed signature page to this Agreement by electronic transmission shall be as effective as delivery of a manually signed counterpart of this Agreement.

Section 5.13.    Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

Section 5.14.    Specific Performance. The parties hereto agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that any party hereto does not perform the provisions of this Agreement (including failing to take such actions as are required of it hereunder to consummate this Agreement) in accordance with its specified terms or otherwise breach such provisions. Accordingly, the parties hereto acknowledge and agree that, prior to any termination of this Agreement in accordance with Section ‎5.06, the parties shall be entitled to an injunction, specific performance and other equitable relief to prevent breaches of this

Agreement and to enforce specifically the terms and provisions hereof, in addition to any other remedy to which they are entitled at law or in equity. Each of the parties agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief on the basis that any other party has an adequate remedy at law or that any award of specific performance is not an appropriate remedy for any reason at law or in equity. Any party seeking an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement shall not be required to provide any bond or other security in connection with any such order or injunction.

Section 5.15.    Non-Recourse.

Without limiting the rights of any party against the other parties hereto, in no event shall any party or any of its Affiliates seek to enforce this Agreement against, make any claims for breach of this Agreement against, or seek to recover monetary damages for breach of this Agreement from, any Non-Recourse Party.
