(a)     The Company is a corporation duly incorporated, validly existing and in good standing under the Laws of the State of Delaware and has the requisite corporate power to carry on its business as presently conducted. The Company is duly qualified to do business as a foreign entity and in good standing in each state or country, if any, in which failure to be so qualified would, individually or in the aggregate, have or reasonably be expected to have a Material Adverse Effect.

(b)     The Company has the requisite corporate power and authority to execute, deliver and perform its obligations under the Transaction Documents and all other instruments, documents and agreements contemplated or required by the provisions of any of the Transaction Documents to be executed, delivered or carried out by the Company hereunder.

(c)     This Agreement constitutes the legal, valid and binding obligation of the Company, enforceable in accordance with its terms, and the execution, delivery and performance of this Agreement by the Company does not and will not conflict with, violate or cause a breach of any Contract to which the Company is a party or any Order to which the Company is subject.

(d)     Schedule 2(d) attached hereto sets forth, a true, complete and correct listing, as of the business day immediately preceding the date of the Closing or the date of the Subsequent Closing (as applicable), of all of the Company’s outstanding (i) shares of Common Stock and (ii) securities convertible into or exchangeable for shares of Common Stock (the “Derivative Securities”), including the applicable exercise price of such Derivative Securities, other than any Derivative Securities issued as director compensation or pursuant to the Company’s Amended and Restated Equity-Based Compensation Plan or the Company’s 2011 Employee Stock Purchase Plan (the “Management Equity”). Except as set forth in Schedule 2(d) and except for any Management Equity, the Company has no other outstanding equity securities.

(e)     (i) As of its respective filing date, each Form 10-K (or, if applicable, Form 10-K/A) and Form 10-Q (or, if applicable, Form 10-Q/A) required to be filed by the Company with the SEC prior to the Closing or the Subsequent Closing, as applicable (such filings, together, the “Company SEC Documents”), complied in all material respects with the applicable requirements of the 1933 Act, the 1934 Act, and the Sarbanes-Oxley Act of 2002, as the case may be, including, in each case, the rules and regulations promulgated thereunder.

(ii)     Except to the extent that information contained in the Company SEC Documents has been revised or superseded by a document the Company subsequently filed with the SEC, the Company SEC Documents do not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

(iii)     The financial statements (including the related notes thereto) included in the Company SEC Documents comply as to form in all material respects with applicable accounting requirements and the published rules and regulations of the SEC with respect thereto, have been prepared in accordance with GAAP applied on a consistent basis during the periods involved (except as may be indicated in the notes thereto) and fairly present in all material respects the consolidated financial position of the Company and its Subsidiaries as of the dates thereof and their respective consolidated results of operations and cash flows for the periods then ended, all in accordance with GAAP and the applicable rules and regulations promulgated by the SEC. Since the date of the most recently filed Company SEC Documents, the Company has not made any change in the accounting practices or policies applied in the preparation of its financial statements, except as required by GAAP, the rules of the SEC or policy or applicable Law.

(iv)     Subsequent to the filing of the Company SEC Documents with the SEC, there has been no material and adverse change or development, or event involving such a prospective change, in the condition, business, properties or results of operations of the Company and its Subsidiaries.

(f)     Subject to the accuracy of the Purchasers’ representations and warranties in Section 3, the offer and sale of the Purchased Securities by the Company to each Purchaser pursuant to and in the manner contemplated by this Agreement will be exempt from the registration requirements of the 1933 Act.

(g)     The Company agrees and acknowledges that the Purchased Securities to be acquired by LSGC Holdings III LLC or any of its Affiliates pursuant to this Agreement are subject to the Registration Rights Agreement and that all Conversion Shares issuable to such Purchasers shall be deemed “Registrable Securities” pursuant to the Registration Rights Agreement.

(h)     Except to the extent waived or otherwise cured in accordance with the terms thereof, the Company has complied in all material respects with the covenants set forth in (i) that certain Term Loan Agreement by and among the Company, the lenders party thereto, and Medley Capital Corporation, as administrative agent for the lenders party thereto, as amended from time to time, and (ii) that certain Loan and Security Agreement by and among the Company, BioLogical Illumination, LLC, the financial institutions from time to time party thereto as lenders, and ACF FINCO I LP, as assignee of FCC, LLC (d/b/a First Capital), as amended from time to time (collectively, the “Debt Facilities”).

3.      Purchaser Representations and Warranties. Each Purchaser, severally and not jointly, hereby represents and warrants with respect to itself to the Company as follows:

(a)     Such Purchaser has the full power and authority to execute and deliver this Agreement and to perform all of its obligations hereunder and thereunder, and to purchase, acquire and accept delivery of the Purchased Securities.

(b)     The Purchased Securities are being acquired for such Purchaser’s own account and not with a view to, or intention of, distribution thereof in violation of the 1933 Act, or any applicable state securities Laws.

(c)     Such Purchaser is knowledgeable in financial matters and is able to evaluate the risks and benefits of an investment in the Purchased Securities. Such Purchaser understands and acknowledges that such investment is a speculative venture, involves a high degree of risk and is subject to complete risk of loss. Such Purchaser has carefully considered and has, to the extent such Purchaser deems necessary, discussed with such Purchaser’s professional legal, tax, accounting and financial advisers the suitability of its investment in the Purchased Securities.

(d)     Such Purchaser is able to bear the economic risk of its investment in the Purchased Securities for an indefinite period of time because the Purchased Securities have not been registered under the 1933 Act and, therefore, cannot be sold unless subsequently registered under the 1933 Act or an exemption from such registration is available. Such Purchaser (i) understands and acknowledges that the Purchased Securities being issued to such Purchaser have not been registered under the 1933 Act, nor under the securities Laws of any state, nor under the Laws of any other country, and (ii) recognizes that no public agency has passed upon the accuracy or adequacy of any information provided to such Purchaser or the fairness of the terms of its investment in the Purchased Securities.

(e)     Such Purchaser has had an opportunity to ask questions and receive answers concerning the terms and conditions of the offering of the Purchased Securities and has had full access to such other information concerning the Company as has been requested.

(f)     This Agreement constitutes the legal, valid and binding obligation of such Purchaser, enforceable against such Purchaser in accordance with its terms, and the execution, delivery and performance of this Agreement by such Purchaser does not and will not conflict with, violate or cause a breach of any Contract to which such Purchaser is a party or any Order to which such Purchaser is subject.

(g)     Such Purchaser became aware of the offering of the Purchased Securities other than by means of general advertising or general solicitation.

(h)     Such Purchaser is an “accredited investor” as that term is defined under the 1933 Act and Regulation D promulgated thereunder, as amended by Section 413 of the Private Fund Investment Advisers Registration Act of 2010 and any applicable rules or regulations or interpretations thereof promulgated by the SEC or its staff.

(i)     Such Purchaser acknowledges that the certificates for the Purchased Shares will contain a legend substantially as follows:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR THE SECURITIES LAWS OF ANY STATE. THE SECURITIES MAY NOT BE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT AND APPLICABLE STATE SECURITIES LAWS OR PURSUANT TO AN APPLICABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF SUCH ACT AND SUCH LAWS.”

Subject to any lock-up or other similar agreement that may apply to the Purchased Shares as may be specifically agreed to with an applicable Purchaser, the requirement that the Purchased Shares contain the legend set forth above shall cease and terminate when such shares are transferred pursuant to Rule 144 promulgated under the 1933 Act. Upon the consummation of an event described in the immediately preceding sentence, the Company, upon surrender of certificates containing such legend, shall, at its own expense (without the need for any opinion of counsel for a Purchaser), deliver to the holder of any such securities as to which the requirement for such legend shall have terminated, one or more new certificates evidencing such securities not bearing such legend.

(j)     Each Purchaser holding 20% or more of the Company’s voting equity securities (as used in Rule 506(d)(1) of the 1933 Act) represents that neither (i) such Purchaser, (ii) any of its directors, executive officers, other officers that may serve as a director or officer of any company in which it invests, general partners or managing members, nor (iii) any beneficial owner of the Company’s voting equity securities (in accordance with Rule 506(d) of the 1933 Act) held by such Purchaser is subject to any Disqualification Event, except for Disqualification Events covered by Rule 506(d)(2) or (d)(3) under the 1933 Act and disclosed reasonably in advance of the Closing in writing in reasonable detail to the Company.

4.      Additional Agreements.

(a)     Purchaser Covenant. Each Purchaser agrees, severally and not jointly, not to make any sale, transfer or other disposition of the Purchased Securities in violation of the 1933 Act, the 1934 Act, the rules and regulations promulgated thereunder or any applicable securities Laws.

(b)     Tax Provision. The Company and each Purchaser intend that for U.S. federal, state and local income tax purposes, the Purchased Securities will be treated as equity.

(c)     Terms of the Preferred Shares. Each of the parties hereto acknowledges that the Series J Preferred Shares shall have the powers, preferences and rights, and be subject to the qualifications, limitations or restrictions set forth in the Series J Certificate of Designation.

(d)     Certain Actions. Promptly following the date hereof, the Company shall take all actions required to promptly prepare and file any required notice of exempt offering of securities, including a Form D, with the SEC pursuant to the 1933 Act and/or other comparable form with state securities regulators with respect to any applicable “blue sky” laws, in each such case, with respect to the transactions contemplated hereby.

(e)      U.S. Real Property Holding Corporation Status.
