 RECITALS 
  
 WHEREAS, immediately prior to the execution of this Agreement, the Company and Seller entered into an Asset Purchase Agreement of even date herewith (as
such agreement may hereafter be amended from time to time, the “Asset Agreement”), a copy of which is attached hereto as Exhibit B, pursuant to which the Company will purchase from Seller the Business Assets and assume

 WHEREAS, each Significant Holder beneficially owns that number of shares of
common stock, no par value, of the Company set forth opposite such Significant Holder’s name on Exhibit A hereto (such shares, together with any other voting securities of the Company beneficially owned (as defined below) by such
Significant Holder, whether heretofore or hereafter acquired, the “Company Shares”); 
  
 WHEREAS, as an inducement and a condition to entering into the Asset Agreement, the Company and Seller have requested that each Significant Holder agree,
and each Significant Holder hereby does agree, to enter into this Agreement; and 
  
 NOW, THEREFORE, in consideration of the foregoing and the mutual premises, representations, warranties, covenants and agreements contained herein, the parties hereto hereby agree as follows: 
  
 1. Definitions. 
  
 (a) “Issuance Proposal” means the Company’s
issuance of the Shares, the Warrant and the Warrant Shares (each as defined in the Asset Agreement) to Seller in accordance with the terms of the Asset Agreement. 
  
 (b) “Opt-Out Proposal” means the amendment to Buyer’s Code of Regulations to opt-out of the
Ohio Control Share Acquisition Act. 
  
 (c)
“Acquisition Proposal” means, with respect to the Company, any offer or proposal or public announcement of a proposal or plan, relating to any transaction or series of related transactions involving: (A) any purchase
from the Company or acquisition by any Person or “group” (as defined under Section 13(d) of the Exchange Act and the rules and regulations thereunder) of more than a fifteen percent (15%) interest in the total outstanding voting
securities of the Company or any of its subsidiaries, directly or indirectly, or any tender offer or exchange offer that if consummated would result in any Person or group beneficially owning fifteen percent (15%) or more of the total
outstanding voting securities of the Company or any of its subsidiaries, directly or indirectly, or any merger, consolidation, business combination or similar transaction involving the Company or any of its subsidiaries or (B) any sale, lease

 1 

 2. Voting Agreement. 
  
 (a) Each Significant Holder hereby agrees with the Company and Seller that, at any meeting of the Company’s
shareholders, however called (including at any adjournment or postponement thereof) and in any consensual action by the Company’s shareholders, each Significant Holder shall vote the Company Shares beneficially owned by such Significant Holder,
whether heretofore owned or hereafter acquired: (i) in favor of the Opt-Out Proposal, the Issuance Proposal and the other transactions contemplated by the Asset Agreement and in favor of any other matter that could reasonably be expected to
facilitate the consummation of the transactions contemplated by the Asset Agreement; and (ii) against (a) any Acquisition Proposal, (b) any change in a majority of the individuals who, as of the date hereof, constitute the
Company’s board of directors (a “Change in Directors”), or (c) any other action which is intended, or could reasonably be expected, to impede, interfere with, delay, postpone or materially adversely affect the
consummation of the transactions contemplated by the Asset Agreement (an “Adverse Transaction”). Each Significant Holder shall not enter into any agreement or understanding with any Person the effect of which would be
violative of the provisions and agreements contained herein. 
  
 (b) For purposes of this Agreement, a Significant Holder shall be deemed to “beneficially own” or to have acquired “beneficial ownership” of a security if such Significant Holder directly or
indirectly has such ownership, control or power to (i) vote or direct the voting with respect to such security, or (ii) dispose or to direct the disposition of such security. Company Shares beneficially owned by any Significant Holder
shall include securities beneficially owned by all other Persons with whom a Significant Holder would constitute a “group” as within the meaning of Section 13(d)(3) of the Exchange Act, other than parties to this Agreement.

  
 3. Irrevocable Proxy. 
  
 (a) Each Significant Holder hereby irrevocably (to the fullest extent
permitted by applicable Law) constitutes and appoints Seller, which shall act by and through Austin Tseng and Yao C.H. Chou (each, a “Proxy Holder”), or either of them, with full power of substitution and resubstitution, as
its true and lawful proxy and sole attorney-in-fact to vote at any meeting (and any adjournment or postponement thereof) of the Company’s shareholders and in any consensual action by the Company’s shareholders, and to exercise all
other voting and related rights with respect to (to the full extent that such Significant Holder is entitled to do so), all Company Shares beneficially owned by such Significant Holder as of the date of such meeting or the taking of any action:
(i) in favor of the approval of the Opt-Out Proposal, the Issuance Proposal and the other transactions contemplated by the Asset Agreement and in favor of any other matter that could reasonably be expected to facilitate the consummation of the
transactions contemplated by the Asset Agreement, and (ii) against any Acquisition Proposal, Change in Directors or Adverse Transaction. Such proxy shall be limited strictly to the power to vote the Company Shares in the manner set forth in the
preceding sentence and shall not extend to any other matters. 
  
 (b) The proxy and power of attorney granted herein shall be irrevocable (to the fullest extent permitted by applicable Law) during the term of this Agreement, shall be deemed to be coupled with an interest sufficient in law to support an
irrevocable proxy and, upon execution of this Agreement, shall revoke all prior proxies granted by any Significant Holder that conflict with the proxy granted herein. Significant Holder shall not grant any proxy to any Person which conflicts with
the proxy granted herein, and any attempt to do so shall be void. The power of attorney granted herein is a durable power of attorney and shall survive the death or incapacity of any Significant Holder. 
  
 (c) If any Significant Holder fails for any reason to vote his or her Company
Shares in accordance with the requirements of Section 2(a) hereof, then the Proxy Holder shall have the right to vote the Company Shares in accordance with the provisions of this Section 3. The vote of the Proxy Holder shall control in any
conflict between his or her vote of such Company Shares and a vote by any Significant Holder of such Company Shares. 
  
 4. Director and Officer Matters Excluded. Each of the Company and Seller hereby acknowledges and agrees that no provision of this Agreement shall
limit or otherwise restrict any Significant Holder with respect to any act 

  

 2 

 
or omission that such Significant Holder may undertake or authorize in his or her capacity as a director or officer of the Company, including, without
limitation, any board vote that such Significant Holder may make as a director of the Company with respect to any matter presented to the Company. 
  
 5. Other Covenants, Representations and Warranties. Each Significant Holder hereby severally and not jointly represents and warrants to the Company
and Seller as follows: 
  
 (a) Ownership of Company
Shares. As of the date hereof, each Significant Holder is the beneficial owner of the number of Company Shares set forth opposite such Significant Holder’s name on Exhibit A hereto (representing all Company Shares beneficially
owned by such Significant Holder), which Company Shares are free and clear of any liens, adverse claims, charges, security interests, pledges or options, proxies, voting trusts or any other encumbrances. With respect to each Significant Holder,
Exhibit A also sets forth all options, warrants and other derivative securities convertible into or exercisable for shares of Company capital stock held by such Significant Holder as of the date hereof. 
  
 (b) Power; Binding Agreement. Each Significant Holder has sole voting
power with respect to the matters set forth in Section 2(a) hereof with respect to all of his or her Company Shares—except in the cases of shared voting power noted in Exhibit A—with no limitations, qualifications or restrictions on
such rights. Each Significant Holder has the legal capacity, power and authority to enter into and perform all of its obligations under this Agreement. The execution, delivery and performance of this Agreement by such Significant Holder will not
violate any agreement or any court order to which such Significant Holder is a party or is subject including, without limitation, any voting agreement or voting trust. This Agreement has been duly and validly executed and delivered by each
Significant Holder. 
  
 (c) Restriction on Transfer, Proxies
and Non-Interference. Except as expressly contemplated by this Agreement, the Significant Holders shall not, directly or indirectly: (i) offer for sale, sell, transfer, tender, pledge, encumber, assign or otherwise dispose of, or enter into
any contract, option or other arrangement or understanding with respect to or consent to the offer for sale, sale, transfer, tender, pledge, encumbrance, assignment or other disposition of (any of the foregoing, a
“Transfer”), any or all of the Company Shares or any interest therein; (ii) grant any proxies or powers of attorney or deposit any Company Shares into a voting trust or enter into a voting agreement, in any such case
that conflicts with Significant Holder’s obligations hereunder, with respect to any Company Shares; or (iii) take any action that would make any representation or warranty of such Significant Holder contained herein untrue or incorrect or
have the effect of preventing or disabling Significant Holder from performing any of Significant Holder’s obligations under this Agreement. 
  
 (d) Permitted Transfers. Notwithstanding Section 5(c), each Significant Holder shall have the right to Transfer Company Shares (x) to the
extent the transferee shall, as a condition to such transfer, execute an agreement to be bound by the terms and conditions of this Agreement, which agreement must be countersigned and accepted by each of the Company and Seller, or (y) pursuant
to the terms of a Rule 10b5-1 trading plan adopted prior to the date of this Agreement. 
  
 (e) Stop Transfer. Each Significant Holder hereby covenants to the Company and Seller that such Significant Holder shall not request that the Company register the transfer (book-entry or otherwise) of any
certificate or uncertificated interest representing any Company Shares, unless such transfer is made in accordance with the terms of this Agreement. 
  
 (f) Quorum. Each Significant Holder further agrees that at any meeting of the Company shareholders, such holder shall, or shall cause the holder of
record on any applicable record date to, appear at such meeting or otherwise cause the Company Shares to be counted as present thereat for purposes of establishing a quorum. 
  
 (g) Disclosure. Each Significant Holder agrees to permit Company and Seller to publish and disclose in all
documents and schedules filed with the SEC, and any press release or other disclosure document that Company or Seller, in its sole discretion, determines to be necessary or desirable in connection with the 

  

 3 

 
transactions contemplated by the Asset Agreement, such Significant Holder’s identity and beneficial ownership of Company Shares and the nature of such
Significant Holder’s commitments, arrangements and understandings under this Agreement. 
  
 (h) Reliance by the Company and Seller. Each Significant Holder understands and acknowledges that the Company and Seller are entering into the Asset Agreement in reliance upon Significant Holder’s
execution and delivery of this Agreement and the accuracy of the representations and warranties made by such Significant Holder herein. 
  
 6. Company Shares. In the event of a stock dividend or distribution, or any change in the Company capital stock by reason of any stock dividend,
split-up, recapitalization, combination, exchange of shares or the like, the term “Company Shares” shall be deemed to refer to and include the Company Shares as well as all such stock dividends and distributions and any
shares into which or for which any or all of the Company Shares may be changed or exchanged. If so requested by Seller, Significant Holder agrees that the Company Shares shall bear a legend stating that such Company Shares are subject to this
Agreement. 
  
 7. Termination. This Agreement shall
terminate upon the earliest to occur of: (a) the termination of the Asset Agreement in accordance with its terms; provided, however, that in the event the Asset Purchase Agreement is terminated by Buyer pursuant to Section 7.1(g)
thereof, this Agreement shall remain in full force and effect for a period of six (6) months following the date of any such termination, and (b) the Closing Date. Upon the termination of this Agreement, this Agreement shall forthwith
become null and void, and there shall be no liability on the part of any party hereto, except (i) that the provisions of this Section 7 and the provisions of Section 9 shall survive the termination of this Agreement and
(ii) nothing herein shall relieve any party from liability for any willful breach hereof. 
  
 8. No Ownership Interest. Nothing contained in this Agreement shall be deemed to vest in Seller any direct or indirect ownership of any Company Shares. All rights, ownership and economic benefits of and
relating to the Company Shares shall remain vested in and belong to the respective Significant Holder. 
  
 9. Miscellaneous. 
  
 (a) Entire Agreement. This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes
all other prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof. 
  
 (b) Certain Events. Each Significant Holder agrees that this Agreement and the obligations hereunder shall attach to the Company Shares and shall
be binding upon any Person to which legal or beneficial ownership of any Company Shares shall pass, whether by operation of law or otherwise. Notwithstanding any transfer of Company Shares, the transferor shall remain liable for the performance of
all of its obligations under this Agreement. 
  
 (c)
Assignment. With respect to any Significant Holder, this Agreement shall not be assigned by operation of law or otherwise without the prior written consent of Seller; and with respect to the Company and Seller, this Agreement shall not be
assigned by operation of law or otherwise without the prior written consent of the other party; provided, however, that Seller may, in its sole discretion, assign its rights and obligations hereunder to any affiliate of Seller. Subject to the
foregoing, this Agreement and all of the provisions hereof shall be binding upon and insure to the benefit of the parties hereto and their respective successors and permitted assigns.

 (i) Other Remedies. Except as
otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any

as may be necessary to elect (and maintain in office) as a member of the Company’s Board, the Shareholder Designee. 
  
 (ii) Shareholder agrees to vote all Company Shares (x) at all annual or special meetings of the Company’s shareholders, however called
(including any postponement or adjournment thereof), and (y) by any consensual action of shareholders of the Company, in each case, in such a manner as may be necessary to elect (and maintain in office) as members of the Company’s Board,

of its affiliates (other than the Company), continues to hold Company Shares or the right to acquire Company Shares representing at least 5% of the Company’s issued outstanding capital stock, Shareholder shall have the right to designate a
representative (the “Board Observer”) to attend all meetings of the Board (whether telephonic or otherwise) in a non-voting observer capacity, and the Company shall give the Board Observer copies of all notices, minutes,
consents and other materials that it provides to its Directors (the “Materials”); provided, however, that the Board Observer and Shareholder shall agree to hold in confidence and trust all Materials so provided to the
same extent as if they were members of the Board; provided, further, that the Board Observer and Shareholder agree to share information gathered from the Materials or to share the Materials only with those directors, officers, employees,
agents or representatives of Shareholder on a need-to-know basis. 
  
 (b) Initial Board Observer; Change of Board Observer. Shareholder shall appoint Austin Tseng as its initial Board Observer. Shareholder, in its sole discretion, may from time to time change the Board Observer; provided,
however, that Shareholder agrees to use commercially reasonable efforts to limit the number of times the Board Observer is changed. Moreover, Shareholder agrees to provide reasonable notice to the Company of a change of its Board Observer prior
to the next scheduled meeting of the Board. 
  
 (c)
Company’s Right to Exclude Board Observer. The Company shall have the right to exclude the Board Observer from any meeting of the Board, or any portion thereof, or to refuse to give the Board Observer access to any Materials, (i) if
in the judgment of the Board, the matters to be discussed would impinge the attorney-client privilege, or (iii) a majority of the members of the Board vote to exclude such representative from a meeting, or any portion thereof, or from receiving
Materials, or any portion thereof. 
  
 (d) Expenses. The
Company shall pay all expenses reasonably incurred by either the Shareholder Designee or the Board Observer, but not both, in connection with such Shareholder Designee’s or Board
