Article
I

Voting


Section
1.01        Seller Covenants to Vote. 



     


     

    




(a)               
During the term of this Agreement, the Seller hereby agrees to vote or cause to be voted, or consent or cause to be consented,
with respect to all matters submitted to a vote or consent, as the case may be, of the Company’s stockholders at any time
during the term of this Agreement, whether the matter is brought before any meeting of the stockholders of the Company however
called, proposed to be taken by written consent of the stockholders of the Company or otherwise, all of the shares of Company Common
Stock owned or held by the Seller, directly or indirectly (the “Seller Shares”), in accordance with the recommendations
or directions of the Company’s Board of Directors (the “Company Board”). For the avoidance of doubt, the
term “Seller Shares” shall include all shares of the Company Common Stock owned or held by the Seller, directly
or indirectly, as of the date hereof (after giving effect to the purchase and sale transaction contemplated by the Asset Purchase
Agreement) and all shares subsequently acquired by the Seller by any means, including, without limitation, upon exercise of any
stock option, warrant or similar purchase right.


(b)              
In furtherance of the voting agreement of the Seller contained in Section 1.01(a), the Seller hereby constitutes
and appoints as the proxy of the Seller, and hereby grants a power of attorney to, the Company and its designees, with full power
of substitution, with respect to all matters submitted to a vote or consent of the Company’s stockholders as contemplated
by Section 1.01(a). The proxy and power of attorney granted pursuant to the immediately preceding sentence is given in consideration
of the agreements and covenants of the parties in connection with the transactions contemplated by the Asset Purchase Agreement
and this Agreement, including the agreements to vote set forth in this Article I, and, as such, each is coupled with an
interest and shall be irrevocable unless and until this Agreement terminates pursuant to Article IV.


(c)               
The Seller hereby revokes any and all previous proxies or powers of attorney with respect to the Seller Shares and shall
not hereafter, unless and until this Agreement terminates pursuant to Article IV, purport to grant any other proxy or power
of attorney with respect to any of the Seller Shares, deposit any of the Seller Shares into a voting trust or enter into any agreement
(other than this Agreement), arrangement or understanding with any person or entity, directly or indirectly, to vote, grant any
proxy or give instructions with respect to the voting of any of the Seller Shares.


(d)              
The Company shall indemnify and hold harmless the Seller and each of his Indemnified Persons (as such term is defined in
the Asset Purchase Agreement, except that for purposes of this Agreement, none of the Company nor any subsidiary of the Company
shall be deemed an Indemnified Person of the Seller) from, against and in respect of any loss (excluding loss of value of the Seller
Shares), liability, claim, damage, cost, fine, deficiency, judgment, award, settlement and expense (including, without limitation,
interest, penalties, costs of investigation and defense and the reasonable fees and expenses of attorneys and experts) (collectively,
“Indemnifiable Expenses”) incurred directly by the Seller in connection with any claim asserted by an unaffiliated
third party against the Seller based upon the voting of the Seller Shares by: (i) such Seller under direction of the Company Board
pursuant to Section 1.01(a); or (ii) the 



    2 


     

    

Company or its designee pursuant to the proxy and power of attorney granted under Section
1.01(b).


Article
II

Transfer


Section
2.01        General Restrictions on Transfer
of Seller Shares.


(a)               
Except as otherwise expressly permitted pursuant to this Article II, the Seller shall not Transfer (as hereinafter
defined) any Seller Shares without the prior written consent of the Company Board, which consent may be granted or withheld in
the sole and absolute discretion of the Company Board.


(b)              
For all purposes of this Agreement, the term “Transfer” means, as a noun, any direct or indirect, voluntary
or involuntary transfer, sale, pledge, encumbrance, assignment, hypothecation, gift, or other disposition and, as a verb, to voluntarily
or involuntarily, directly or indirectly, transfer, sell, assign, pledge, encumber, hypothecate, give, or otherwise dispose of,
any of the Seller Shares.


Section
2.02        Permitted Transfers. The
Seller shall be free at any time (without the consent of the Company but, in the case of clauses (i) and (ii) of this sentence,
upon at least five business days advance written notice to the Company) to Transfer all or any portion of his Seller Shares: (i)
to a trust or estate, limited liability company, limited partnership or similar vehicle owned or controlled by such Seller; and
(ii) to Symmetric or the Company (whether pursuant to the provisions of this Article II or otherwise). Seller Shares may
also be Transferred upon such Seller’s death or involuntarily by operation of law. In addition, Seller Shares may be Transferred
pursuant to a merger, consolidation or other business combination involving Company Common Stock that has been approved by the
Company Board and otherwise in compliance with all applicable laws, rules and regulations. Notwithstanding the foregoing, in the
case of any Transfer permitted under this Section 2.02 (other than a permitted Transfer pursuant to the preceding sentence
or clause (ii) of this Section 2.02), it shall be a condition to such Transfer that such transferee agrees, by executing
a joinder agreement in substantially the form attached hereto as Exhibit A (y) to be bound by this Agreement as a Seller
with respect to all of the Seller Shares Transferred to such transferee, and (z) that all of the Seller Shares Transferred to such
transferee remain subject to this Agreement and all of the terms, conditions and restrictions hereof as Seller Shares.


Section
2.03        Right of First Refusal.


(a)               
If, following the one year anniversary of the date hereof, the Seller (an “Offering Stockholder”) receives
a bona fide offer (the “Offer”) from any unaffiliated third party (a “Third Party Purchaser”)
to purchase any or all of the Seller Shares 



    3 


     

    

owned by such Seller (the “Offered Shares”) and the Offering Stockholder
desires to Transfer the Offered Shares to the Third Party Purchaser pursuant to such Offer, then the Offering Stockholder must
first make an offering of the Offered Shares to the Company in accordance with the provisions of this Section 2.03.


(b)              
The Offering Stockholder shall, within five business days after receipt of the Offer from the Third Party Purchaser, give
written notice (the “Offering Stockholder Notice”) to the Company stating that it has received a bona fide offer
from a Third Party Purchaser and specifying:


(i)                
the number of Offered Shares proposed to be Transferred by the Offering Stockholder;


(ii)              
the identity of the Third Party Purchaser;


(iii)            
the per share purchase price and the other material terms and conditions of the Transfer, including a description of any
non-cash consideration in sufficient detail to permit the valuation thereof; and


(iv)            
the proposed date, time and location of the closing of the Transfer, which shall not be less than 60 days from the date
of the Offering Stockholder Notice. The Offering Stockholder Notice shall constitute the Offering Stockholder's offer to Transfer
the Offered Shares to the Company, which offer shall be irrevocable for the ROFR Notice Period (as hereinafter defined).


(c)               
Upon receipt of the Offering Stockholder Notice, the Company shall have thirty days (the “ROFR Notice Period”)
to elect, in its sole discretion, to purchase all, but not less than all, of the Offered Shares on the terms specified in the Offering
Stockholder Notice (subject to the right of the Company pursuant to Section 2.03(e) below to pay the purchase price solely
in cash), by delivering a written notice of such election (a “ROFR Notice”) to the Offering Stockholder. Any
ROFR Notice shall be binding upon delivery and irrevocable by the Company.


(d)              
If the Company elects to purchase all, but not less than all, of the Offered Shares pursuant to this Section 2.03,
the Company and the Offering Stockholder shall take all actions as may be reasonably necessary to consummate the purchase and sale
of such Offered Shares, including entering into agreements and delivering certificates and instruments and consents as may be deemed
necessary or appropriate, and making all payments in connection therewith, within 30 days after delivery of the ROFR Notice (or
if such 30 day period expires during a period in which “insiders” of the Company are prohibited from purchasing or
selling securities of the Company and such prohibition applies to the exercise of the Company’s rights hereunder, within
10 days following the expiration of such restricted period). Notwithstanding anything to the contrary contained herein, if all
or any portion of the consideration proposed to be paid by the Third Party Purchaser for the Offered Shares as set forth in the
Offering Stockholder Notice is other than cash, the Company shall have the option exercisable in its sole discretion by specifying
the same in the ROFR Notice to pay the purchase price solely in cash, in 



    4 


     

    

which case the fair market value of the proposed non-cash
consideration shall be determined in good faith by the disinterested members of the Company Board. All cash payments shall be paid
by wire transfer of immediately available funds to an account designated in writing by the Offering Stockholder to the Company.


(e)               
If the Company does not elect in an ROFR Notice delivered during the ROFR Notice Period to purchase all, but not less than
all, of the Offered Shares, (i) the Company shall be deemed to have waived their rights to purchase the Offered Shares under this
Section 2.03, and (ii) the Offering Stockholder may, during the 60-day period immediately following the expiration of the
ROFR Notice Period and subject to Section 2.03(g), Transfer to the Third Party Purchaser all but not less than all of the
Offered Shares on terms and conditions no more favorable to the Third Party Purchaser than those set forth in the Offering Stockholder
Notice. If the Offering Stockholder does not Transfer the Offered Shares within such period, the rights provided under this Section
2.03 shall be deemed to be revived and the Offered Shares shall not be Transferred to the Third Party Purchaser or otherwise
pursuant to this Section 2.03 unless the Offering Stockholder sends a new Offering Stockholder Notice in accordance with,
and otherwise complies with, this Section 2.03.


(f)               
Notwithstanding anything to the contrary contained herein, it shall be a condition to any Transfer of Offered Shares pursuant
to this Section 2.03 that the Third Party Purchaser to whom or which the Offered Shares are Transferred agrees, by executing
a joinder agreement in substantially the form attached hereto as Exhibit A, (i) to be bound by this Agreement as a Seller
with respect to all of the Offered Shares Transferred to such Third Party Purchaser, and (ii) that all of the Offered Shares Transferred
to such Third Party Purchaser remain subject to this Agreement and all of the terms, conditions and restrictions hereof as Seller
Shares.


Section
2.04        Tag-Along Rights.


(a)               
If Symmetric elects to sell (either in a single or a series of related transactions) shares representing 25% or more of
the shares (collectively the “Symmetric Shares”) of Common Stock owned by Symmetric and Nahmad (such shares
desired to be so Transferred, the “Transferor Shares”)) to an unaffiliated third party (a “Tag Buyer”),
then, at least 30 days prior to the date upon which Symmetric intends to consummate such Transfer, Symmetric shall give written
notice thereof which notice shall set forth the consideration to be paid by the Tag Buyer, and the other material terms and conditions
of such transaction (such notice, the “Transferor Notice”). Each Seller shall have the right (the “Tag-Along
Right”) to sell to the Tag Buyer, at such Seller’s option, the percentage of his Seller Shares equal to the percentage
of the Transferor Shares being Transferred in the transaction compared to all of Symmetric Shares owned by Symmetric at that time
(the “Ratable Percentage Shares”), on the same terms and conditions, including price, upon which Symmetric is
Transferring the Transferor Shares. Each Seller shall have 30 days following receipt of the Transferor Notice to elect to sell
all or a portion of the 



    5 


     

    

Seller’s Ratable Percentage Shares. The failure of the Seller to notify Symmetric of its election
of the Tag-Along Right within such 30 day period shall be deemed to constitute a waiver of the Seller’s Tag-Along Right with
respect to such Transfer. If the Tag Buyer is unwilling to purchase the Transferor Shares and all of the Seller Shares desired
to be sold by the Seller if he is exercising the Tag-Along Right, then, at Symmetric’s sole option, either (i) the transaction
shall not be consummated or (ii) each of the Transferor Shares and the Seller Shares desired to be sold in the transaction by Seller
exercising the Tag-Along Right shall be ratably reduced to equal an amount of shares determined by multiplying the Transferor Shares
or the applicable Seller Shares, as the case may be, by a fraction, the numerator of which is the total number of shares which
the Tag Buyer agrees to purchase in the transaction and the denominator of which is the total number of Transferor Shares and Seller
Shares desired to be sold in the transaction.


(b)              
Each Seller who exercises the Tag-Along Right shall take such actions as reasonably necessary to consummate the applicable
transaction, including, without limitation, to execute and deliver a definitive purchase and sale (or other similar) agreement,
in substantially the same form and substance as the definitive agreement executed and delivered by Symmetric; provided, that (A)
the representations and warranties relating specifically to the Seller if participating in the transaction shall be made only by
the Seller and any indemnification provided by the Seller participating in the transaction with respect to the Company, if any,
shall be based on the shares being Transferred by each of them vis a vis all of the shares in the Company being Transferred
in the transaction, on a several, not joint, basis, (B) the Seller shall not be required to provide any indemnity in such transaction
that provides for liability to such Seller in excess of the amount of proceeds actually received by the Seller in such transaction,
and (C), each of Symmetric and the Seller participating in the transaction shall bear its or his pro rata share of the costs of
the transactions based on the net proceeds to be received by each such person in connection with the transaction to the extent
such costs are incurred for the benefit of persons selling shares in the transaction and are not paid by the Tag Buyer.


(c)               
Symmetric shall have 120 days following the date of the Transferor Notice in which to consummate a transaction subject to
this Section 2.04 on the terms set forth in the Transferor Notice (which 120-day period shall be extended for a reasonable
time to the extent reasonably necessary to obtain any regulatory approvals or if necessary to enable Symmetric and the Seller as
an insider of the Company to engage in a transaction in the securities of the Company). If at the end of such period, Symmetric
has not completed the transaction other than as a result of any action or inaction by a Seller in breach of this Agreement, Symmetric
may not then effect a transaction subject to this Section 2.04 without again fully complying with the provisions of this
Section 2.04.
