SECTION 1

PREEMPTIVE RIGHTS

1.1 Preemptive Rights. Subject to the restrictions on preemptive rights contained in Section 1.2 below, prior to the consummation of any proposed issuance or sale by the Corporation of any shares of its capital stock including any treasury shares (e.g., authorized but unissued shares), such shares shall first be offered (on the same terms and conditions as so proposed to be issued or sold) to the Shareholders in proportion to their respective holdings, all as more fully set forth below:

(a) Said terms and conditions shall be communicated in writing to each Shareholder at their address appearing on the books of this Corporation, together with a statement of their rights hereunder.

(b) Each Shareholder shall have the option to acquire their proportion (i.e., a fraction, the numerator of which is the number of shares held by such Shareholder prior to the new issuance and the denominator of which is the total number of issued and outstanding shares held by all Shareholders prior to the new issuance) of the capital stock so proposed to be issued or sold, on the same terms and conditions. Such option shall be exercised by delivery of written notice of exercise to the principal office or statutory agent of this Corporation within ten (10) business days after receipt of the communication referred to in Section 1.1(a) above. An option may be exercised as to all shares subject thereto or in part.

(c) In the event any Shareholder shall fail or decline to exercise his preemptive option as aforesaid, such Shareholder’s proportion of said capital stock may be acquired by the Shareholders who have exercised their options up to a number of shares in proportion to the number of shares subject to their options. Such option shall be exercised by delivery of written notice of exercise to the principal office or statutory agent of this Corporation within ten (10) business days after receipt of a communication from the Corporation as to the availability of such shares. The option may be exercised as to all shares subject thereto or in part.

(d) Any acquisition of capital stock pursuant to the preemptive rights conferred by this provision shall be closed on or before the date which is the later of (i) thirty (30) business days after receipt by the Corporation of the last written notice of exercise given pursuant to Section 1.1(b) or Section 1.1(c) above, or (ii) the date of the proposed issuance giving rise to such rights, as set forth in the notice given pursuant to Section 1.1(a) above. In the event the Corporation has not sold such capital stock within such time periods, the Corporation shall not thereafter issue or sell any shares of capital stock without first again offering such shares of capital stock to the Shareholders in accordance with the procedures set forth in this Section 1.1.

1.2 Restrictions on Preemptive Rights. All preemptive rights under Section 1.1 above shall be subject to the following limitations and restrictions:

(a) Such preemptive rights shall apply to the issuance of capital stock by any subsidiary or to be formed subsidiary of the Corporation unless such subsidiary or to be formed subsidiary is issuing the capital stock in connection with the Corporation entering into a joint venture arrangement or other strategic relationship whose sole purpose is to further the business of the Corporation.

(b) Such preemptive rights shall not apply to (i) the Corporation’s issuance of any Non-Voting Common Stock or issuance of any Common Stock upon the conversion of any Non-Voting Common Stock or Preferred Stock, (ii) the issuance of any of the Corporation’s capital stock, or options therefor, pursuant to an Award (as defined in the Corporation’s 2013 Equity Award Plan) granted under the Corporation’s 2013 Equity Award Plan and/or (iii) any subsequently approved equity compensation plan approved by a majority of the directors of the Corporation who are not officers or employees of the Corporation and the issuance of any of the Corporation’s capital stock, or options therefore, granted under such plan.

Xxxx, Xxxxx Xxxxx, Xxx Xxxxxx (or their respective heirs described in Section 2.2(b)) and B&V will cause such Shareholder’s director to execute a confidentiality agreement with the Corporation.

Tender shall be made by giving notice of tender to the Corporation and to the other Shareholders. The notice shall state the number of shares to be transferred, the name and address of the person giving the notice and of the transferee, and the nature of the transfer.

5.3 Acceptance by Corporation. Within twenty (20) days following the giving of a notice of tender, the Corporation may accept the tender and purchase all or any part of the shares tendered.

5.4 Acceptance by Shareholders. If the Corporation fails to exercise its option to purchase all or any part of the shares tendered, the other Shareholders may accept the tender and purchase the shares not purchased by the Corporation. The other Shareholders may accept the tender at any time within twenty (20) days following the expiration of the period for the Corporation’s acceptance of the tender.

5.5 Additional Acceptances by Shareholders. The other Shareholders shall have the right to accept the tender and purchase the tendered shares in the same ratio as the number of shares of the Corporation owned by each of them bears to the number of shares of the Corporation owned by all of them. If any of the other Shareholders does not elect to purchase the shares allocated to such Shareholder, any of the other Shareholders shall, within ten (10) days following the expiration of the period for the other Shareholders’ acceptance of the tender, have the right to accept the tender and purchase all or any part of the remaining shares tendered. If more than one of the other Shareholders elect to purchase the remaining shares, such Shareholders shall have the right to purchase the shares in the same ratio as the number of shares of the Corporation owned by each of them bears to the number of shares of the Corporation owned by all of them, or on any other basis that they may agree upon.

5.6 Purchase of All Shares Required. Notwithstanding any other provision of this Agreement, no acceptance of tender shall be effective unless the tender is accepted by the Corporation or by one or more of the other Shareholders as to all shares tendered.

5.7 Notice of Acceptance. A tender shall be accepted by giving notice of acceptance to the party giving notice of the tender.

5.8 Nonacceptance of Tender. If a tender is not accepted, the shares subject to the tender may be transferred as permitted in Section 4.2 of this Agreement. If such transfer is not consummated within the time period in Section 4.2(d), the right provided under this Section 5 shall be deemed to be revived and the shares subject to the tender shall not be transferred until this Section 5 is complied with.

SECTION 6

PURCHASE PRICE AND TERMS OF PAYMENT

6.1 Proposed Sale of Shares. If shares are to be purchased by the Corporation or other Shareholders pursuant to a tender because the Shareholder-transferor intends to sell the shares by voluntary sale to a third party, the purchase price shall be the price for which the Shareholder-transferor intends to sell the shares plus ten percent (10%). Unless the Shareholder-transferor agrees otherwise, the Corporation or other Shareholders, as the case may be, shall purchase the shares upon the terms the Shareholder-transferor intends to sell the shares.

SECTION 7

TAG ALONG RIGHTS

7.1 Tag Along Right of Sale When Majority Interest Is Being Purchased. If any Shareholder-transferor(s) serves a tender notice in accordance with Section 5 of this Agreement in connection with a Bona Fide Offer which provides for a sale, the completion of which would result in the ownership by the offeror(s) of a majority of the shares of the Corporation, and should any of the other Shareholders decide they wish to sell their shares to the offeror(s) on the same terms and conditions as contained in the Bona Fide Offer, then the Shareholder-transferor(s) serving the tender notice shall not be entitled to sell, transfer or otherwise dispose of their shares unless the offeror(s) purchase at the same time and on the same terms and conditions all of the shares of the other Shareholders who so desire to sell their shares.

7.2 Tag Along Acceptance / Rejection. Any Shareholder having the right to have his shares purchased pursuant to Sections 7.1 shall accept or reject this right by delivering to the Shareholder-transferor(s) and the offeror(s) written notice of his intentions within the time period prescribed under Section 5.4. Failure to deliver the required notice of acceptance or rejection within the time period specified in the preceding sentence shall be deemed to be a rejection of the purchase offer. If any Shareholder accepts the right to have his shares purchased pursuant to Section 7.1, then:

(a) Such Shareholder shall negotiate in good faith with the offeror(s) to consummate the transaction contemplated by the applicable tender notice and the Shareholder’s acceptance of his right to have his shares purchased pursuant to Section 7.1;

(b) Any representations and warranties made by such Shareholder (and any liabilities resulting therefrom) pertaining to the consummation of the aforementioned transaction will be several; and

(c) The consummation of the aforementioned transaction will occur on or before the date which is the later of (i) the closing date specified in the tender notice given under Section 5 (unless waived by the parties thereto) or (ii) 180 days after the tender notice is given under Section 5.
