The execution, delivery and performance of this Agreement and the Distribution Agreement by the Company and the consummation by the Company of the transactions contemplated hereby and thereby do not and will not (a) violate any provision of the Company’s Restated Articles of Incorporation or Bylaws, each as amended to date, (b) constitute a default (or an event which with notice or lapse of time or both would become a default) under, result in the creation of any lien upon any of the property or assets of the Company or the Subsidiary, or give to others any rights of termination, amendment, acceleration or cancellation (with or without notice, lapse of time or both) of, any agreement, credit facility, debt or other instrument to which the Company or the Subsidiary is a party or by which the Company’s or the Subsidiary’s property or assets are bound, or (c) result in a violation of any federal, state, local or foreign statute, rule, regulation, order, judgment or decree (including federal and state securities laws and regulations) applicable to the Company or the Subsidiary or by which any property or asset of the Company or the Subsidiary is bound or affected, except in the case of clauses (b) and (c) for such as would not, individually or in the aggregate, have or reasonably be expected to have a Material Adverse Effect.

3.5 Governmental Approvals The Company is not required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or governmental agency in order for it to execute or deliver this Agreement or the Distribution Agreement or perform any of its obligations under this Agreement or the Distribution Agreement (other than the filing of Form D, a Form 8-K and a Form 10-Q with the SEC (as hereinafter defined), any notices, filings, consents and approvals which may be required to be made by the Company under applicable state securities laws, rules or regulations, and the filing of notice of issuance of the Shares with the NASDAQ Stock Market, prior to or subsequent to the Closing, and in the case of the Distribution Agreement, approvals and notices in connection with the construction of a new facility and to federal regulators (a) necessary to conduct the Company’s business in the ordinary course, or (b) that would be required in the operation of the Company’s business in the absence of the Distribution Agreement).

The Company has reserved from its duly authorized capital stock the number of Shares to be issued under this Agreement.

3.7 Capitalization. The authorized capital stock of the Company is as set forth in the Company SEC Documents.

The issuance and sale of the Shares will not obligate the Company to issue shares of Common Stock or other securities to any Person (other than the Purchaser) and will not result in a right of any holder of Company securities to adjust the exercise, conversion, exchange or reset price under any of such securities.

satisfactory to the Company, to the effect that such sale or transfer is exempt from the registration requirements of the Securities Act.

The shares represented by this certificate have not been registered under the Securities Act of 1933, as amended, and may not be offered, sold or otherwise transferred, pledged or hypothecated unless and until such shares are registered under such Securities Act or an opinion of counsel satisfactory to the Company is obtained to the effect that such registration is not required. Such shares are also subject to a restriction on transfer contained in an Investment Agreement, dated as of October 2, 2014. A copy of the Investment Agreement is available at the Company’s principal executive offices.

The Company shall remove the legend from the certificates representing any Restricted Shares at the request of the holder thereof at such time as they are sold pursuant to an effective registration statement under the Securities Act or an exemption from the registration requirements of the Securities Act.

(ii) engage, or become a participant, in any “solicitation” of “proxies” (as such terms are defined in Regulation 14A under the Exchange Act) or consents to vote any shares of Common Stock;

(v) publicly disclose any intention, plan or arrangement inconsistent with the foregoing; or

(vi) advise, assist or encourage any other Persons in connection with any of the foregoing or to do any of the foregoing.

(b) The obligations of the Purchaser under Section 7.2(a) shall terminate in the event (i) any bona fide third party tender or exchange offer is publicly announced and commenced by any Person other than the Purchaser or an Affiliate of the Purchaser for at least 50% of the outstanding shares of Common Stock that is conditioned upon the offeror receiving tenders for at least 50% of the outstanding shares of Common Stock, or (ii) the Company enters into any agreement to merge or enter into a statutory share exchange with any Person other than the Purchaser or an Affiliate of the Purchaser following the closing of which the Common Stock would cease to be registered under the Exchange Act. All of the provisions of Section 7.2(a) shall be reinstated and shall apply in full force according to their terms in the event that: (A) if the provisions of Section 7.2(a) shall have terminated as the result of clause (i), and such tender or exchange offer (as originally made or as amended or modified) shall have terminated without acquisition by the Offeror of at least 50% of the outstanding shares of Common Stock; or (B) if the provisions of Section 7.2(a) shall have terminated as a result of clause (ii), such merger or share exchange agreement shall have been terminated prior to its closing. Upon reinstatement of the provisions of Section 7.2(a), the provisions of this Section 7.2(b) shall continue to govern in the event that any of the events described in this Section 7.2(b) shall subsequently occur.

(c) Except as otherwise provided in Section 7.2(b), the covenants in this Section 7.2 shall remain in effect until the earlier of (i) the expiration or termination of the Distribution Agreement, or (ii) one year following the receipt of notice from Purchaser that neither it nor any of its Affiliates own, beneficially or of record, the Shares.

7.3 Indemnification.

(a) The Company shall indemnify, defend and hold harmless the Purchaser and its officers, directors, employees and agents from and against and in respect of, and shall compensate and reimburse the foregoing persons for, all losses, deficiencies, damages, expenses, liabilities, claims, assessments and judgments (regardless of whether or not such losses, deficiencies, damages, expenses, liabilities, claims, assessments and judgments involve or relate to a third party claim, and shall include consequential damages, diminution in value and reasonable costs and attorneys’ fees and other expenses arising out of any claim, or the defense or investigation thereof, made with respect to any of the foregoing) (collectively, the “Indemnifiable Expenses”) incurred or suffered by the Purchaser and its officers, directors, employees or agents arising out of, based upon or resulting from any breach by the Company of any of the Company’s representations or warranties set forth in Section 3 of this Agreement.

(b) The Purchaser shall indemnify and hold harmless the Company and its officers, directors, employees and agents from and against and in respect of any Indemnifiable Expenses incurred or suffered by the Company or its officers, directors, employees and agents arising out of, based upon or resulting from any breach by the Purchaser of the Purchaser’s representations or warranties set forth in Section 4 of this Agreement.

(c) Notwithstanding any other provision in this Agreement to the contrary, neither party shall in any event be liable on account of any indemnification obligation set forth in this Section 7.3 for any punitive damages, and such damages shall not constitute Indemnifiable Expenses, except to the extent such damages are awarded to a third party in connection with a third party claim made against any person or entity entitled to indemnification under this Section 7.3.

(d) The representations and warranties contained in Sections 3 and 4 of this Agreement shall survive the Closing for 24 months, except for the representations and warranties in Sections 3.1, 3.2, 3.3, 3.5, 3.6, 3.7, 3.19, 3.23, 3.26, 4.1, 4.2, 4.7, 4.8, 4.9, 4.10 and 4.11, which shall survive until the relevant statute of limitations has run.

(e) Indemnification pursuant to this Section 7.2 shall not preclude any party from exercising any other remedies they may have under this Agreement, applicable law or otherwise.
