SSN-002), in the aggregate outstanding principal amount of $3,000,000 (of which principal amount $1,000,000 shall be paid by the Company to Longview pursuant to the Securities Purchase Agreement (as defined below)), issued by the Company (each an “Old Note” and, together, the “Old Notes”), and a warrant to purchase 4,958,678 shares of Common Stock (as defined below) (the “Old Warrant” and, together with the North Texas Shares, the North Texas Note and the Old Notes, each an “Exchanged Security” and, collectively, the “Exchanged Securities”).

▇. ▇▇▇▇▇▇▇ wishes to acquire from the Company, and the Company wishes to issue to Marquis, on the Closing Date (as defined in Section 1(b)), upon the terms and conditions stated in this Agreement, (i) an unsecured subordinated promissory note, in the form attached as Exhibit A, in an original aggregate principal amount of $9,440,000 (such note, together with any promissory note or other securities issued in exchange or substitution therefor or replacement thereof, and as any of the same may be amended, supplemented, restated or modified and in effect from time to time, the “Marquis Note”) and (ii) a warrant, in the form attached as Exhibit B, to acquire 1,000,000 shares (subject to adjustment) of the Company’s common stock, par value $0.001 per share (“Common Stock”), at an initial exercise price per share of $0.01 (such warrant, together with any warrant or other securities issued in exchange or substitution therefor or replacement thereof, and as any of the same may be amended, supplemented, restated or modified and in effect from time to time, being referred to as the “Warrant”; and the shares of Common Stock issuable from time to time upon exercise of the Warrant being referred to as the “Warrant Shares”), in exchange for the North Texas Shares and the North Texas Note.

E.

F. Contemporaneously with the closing of the purchase and sale of the Sub Notes and the Warrant (the “Closing”), the Company will execute and deliver a Securities Purchase Agreement, in the form attached as Exhibit C (as the same may be amended, supplemented, restated or modified and in effect from time to time, the “Securities Purchase Agreement” and, together with each of the documents and agreements entered into pursuant thereto, the “Securities Purchase Documents”), pursuant to which the Company shall sell to Marquis and any other purchasers named therein, and Marquis and any other purchasers named therein shall purchase from the Company, senior secured promissory notes issued by the Company (the “Senior Notes”) and warrants to acquire 1,050,000 shares of Common Stock, upon the terms and conditions stated in the Securities Purchase Documents, the proceeds of such sale to be used in part to pay $1,000,000 in principal of the Old Notes.

G. Contemporaneously with the Closing, each of the Subsidiaries will execute and deliver a Guaranty, in the form attached hereto as Exhibit D (as the same may be amended, supplemented, restated or modified and in effect from time to time, together, the “Guaranty”), pursuant to which the Subsidiaries will agree to guaranty certain obligations of the Company (the guarantees under the Guaranty, including any such guarantee added after the Closing, being referred to herein as the “Guarantees”).

H. Contemporaneously with the Closing, the Company, North Texas, Marquis and Longview will execute and deliver a Subordination Agreement in the form attached as Exhibit E (as the same may be amended, supplemented, restated or modified and in effect from time to time, together, the “Subordination Agreement”), pursuant to which the parties thereto shall agree, among other things, that interest may be paid on the Sub Notes (as defined in the Securities Exchange Agreement) only so long as there is no event of default under the Senior Notes, but no payments of principal may be made on the Sub Notes (except in the form of junior securities) until the Senior Notes have been repaid in full.

The Closing shall occur on the Closing Date at the offices of ▇▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ LLP, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇, or at such other place as the Company and Marquis may designate in writing. As used in this Agreement, “Business Day” means any day other than Saturday, Sunday or other day on which commercial banks in the New York City are authorized or required by law to remain closed.

2. BUYER REPRESENTATIONS AND WARRANTIES.

Each Buyer, individually and not jointly and severally, represents and warrants, as of the date of this Agreement and the Closing Date, with respect to only itself, that:

a. Investment Purpose. Such Buyer (i) is acquiring the Sub Notes (along with the related Guarantees) and the Warrant acquired by such Buyer hereunder, (ii) upon any exercise of the Warrant, will acquire the Warrant Shares issuable upon such exercise thereof, and (iii) upon any exercise of the Investor Share Option (as defined in each of the Sub Notes), will acquire the shares of Common Stock issuable upon such exercise thereof (the “Option Shares” and, collectively with the Sub Notes, the Guarantees, the Warrant and the Warrant Shares, the “Securities”) for its own account and not with a view towards, or for resale in connection with, the public sale or distribution thereof, except pursuant to sales registered under, or exempted from the registration requirements of, the 1933 Act; provided, however, that by making the representations herein, such Buyer does not agree to hold any of the Securities acquired by it for any minimum or other specific term and reserves the right to dispose of the Securities at any time in accordance with or pursuant to an effective registration statement or an exemption from registration under the 1933 Act.

b. Accredited Investor Status. Such Buyer is an “accredited investor” as that term is defined in Rule 501(a) of Regulation D.

c. Reliance on Exemptions. Such Buyer understands that the Securities are being offered and sold to it in reliance on specific exemptions from the registration requirements of the securities laws and that the Company is relying in part upon the truth and accuracy of, and such Buyer’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of such Buyer set forth herein in order to determine the availability of such exemptions and the eligibility of such Buyer to acquire the Securities. For purposes hereof, “securities laws” means the securities laws, legislation and regulations of, and the instruments, policies, rules, orders, codes, notices and interpretation notes of, the securities regulatory authorities (including the SEC) of the United States and any applicable states and other jurisdictions.

d. Information. Such Buyer and its advisors, if any, have been furnished with all materials relating to the business, finances and operations of the Company and the Subsidiaries and materials relating to the offer and sale of the Securities that have been requested by such Buyer. Such Buyer and its advisors, if any, have been afforded the opportunity to ask questions of the Company. Neither such inquiries nor any other due diligence investigations conducted by such Buyer or its advisors, if any, or its representatives shall modify, amend or affect such Buyer’s right to rely on the Company’s representations and warranties contained in Section 3 below or contained in any of the other Transaction Documents. Such Buyer understands that its investment in the Securities involves a high degree of risk. Such Buyer has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of the Securities.

e. No Governmental Review. Such Buyer understands that no Governmental Entity has passed on or made any recommendation or endorsement of the Securities or the fairness or suitability of an investment in the Securities nor have such authorities passed upon or endorsed the merits of the offering of the Securities. As used in this Agreement, “Governmental Entity” means the government of the United States or any other nation, or any political subdivision thereof, whether state, provincial or local, or any agency (including any self-regulatory agency or organization), authority, instrumentality, regulatory body, court, central bank or other entity exercising executive, legislative, judicial, taxing, regulatory or administration powers or functions of or pertaining to government over the Company or any of the Subsidiaries, or any of their respective properties, assets or undertakings.

f. Transfer or Resale. Such Buyer understands that: (i) the Securities have not been and are not being registered under the 1933 Act or any other securities laws, and may not be offered for sale, sold, assigned or transferred unless (A) subsequently registered thereunder, (B) such Buyer shall have delivered to the Company an opinion of counsel, in a generally acceptable form, to the effect that such Securities to be sold, assigned or transferred may be sold, assigned or transferred pursuant to an exemption from such registration, or (C) such Buyer provides the Company with reasonable assurance that such Securities can be sold, assigned or transferred pursuant to Rule 144 promulgated under the 1933 Act, as amended (or a successor rule thereto) (“Rule 144”); (ii) any sale of the Securities made in reliance on Rule 144 may be made only in accordance with the terms of Rule 144, and further, if Rule 144 is not applicable, any resale of the Securities under circumstances in which the seller (or the Person through whom the sale is made) may be deemed to be an underwriter (as that term is defined in the ▇▇▇▇ ▇▇▇) may require compliance with some other exemption under the 1933 Act or any other securities laws; and (iii) neither the Company nor any other Person is under any obligation to register the Securities under the 1933 Act or any other securities laws. Notwithstanding the foregoing, the Securities may be pledged in connection with a bona fide margin account or other loan or financing arrangement secured by the Securities. As used in this Agreement, “Person” means an individual, a limited liability company, a partnership, a joint venture, a corporation, a trust, an unincorporated organization or a Governmental Entity or any other legal entity.

g. Legends. Such Buyer understands that the certificates or other instruments representing the Securities, except as set forth below, shall bear a restrictive legend in the following form (the “1933 Act Legend”) (and a stop-transfer order may be placed against transfer of such certificates):

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS OR (B) AN OPINION OF COUNSEL, IN A GENERALLY ACCEPTABLE FORM, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR APPLICABLE STATE SECURITIES LAWS OR (II) UNLESS SOLD PURSUANT TO RULE 144 UNDER SAID ACT. NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.

Upon the written request to the Company of a holder of a certificate or other instrument representing any Securities, the 1933 Act Legend shall be removed and the Company shall issue a certificate without the 1933 Act Legend to the holder of the Securities upon which it is stamped, if (i) such Securities are registered for resale under the 1933 Act, (ii) in connection with a sale transaction, such holder provides the Company with an opinion of counsel, in a generally acceptable form, to the effect that a public sale, assignment or transfer of the Securities may be made without registration under the 1933 Act, (iii) such holder provides the Company with reasonable assurances that the Securities can be sold pursuant to Rule 144 without compliance with Rule 144(e) or Rule 144(f) (or successors thereto), (iv) such holder provides the Company reasonable assurances that the Securities have been or are being sold pursuant to Rule 144, or (v) such holder certifies, on or after the date that is six (6) months after the date on which such holder acquired the Securities (or is deemed to have acquired the Securities under Rule 144), that such holder is not an “affiliate” of the Company (as defined in Rule 144). Any Option Shares issued pursuant to the Investor Share Option on or after the date that is six (6) months after the Closing Date to any Buyer that certifies that such Buyer is not an affiliate of the Company, as defined in Rule 144, shall be issued without the 1933 Act Legend. The Company shall be responsible for the fees of its transfer agent and all of The Depository Trust Company (the “DTC”) fees associated with such issuance. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the holders of the Securities. Accordingly, the Company acknowledges that the remedy at law for a breach of its obligations under this Section 3(g) will be inadequate and agrees that, in the event of a breach or threatened breach of this Section 3(g), such holder shall be entitled, in addition to all other available remedies, to an injunctive order and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing economic loss and without any bond or other security being required.

h. Authorization; Enforcement; Validity. Such Buyer is a validly existing limited partnership and has the requisite limited partnership power and authority to purchase the Securities pursuant to this Agreement. This Agreement has been duly and validly authorized, executed and delivered on behalf of such Buyer and is the valid and binding agreement of such Buyer enforceable against such Buyer in accordance with its terms. Each of the Transaction Documents and the other documents entered into and executed by such Buyer in connection with the transactions contemplated hereby and thereby as of the Closing will have been duly and validly authorized, executed and delivered on behalf of such Buyer as of the Closing Date, and will constitute valid and binding agreements of such Buyer, enforceable against such Buyer in accordance with their respective terms.

i. Residency and Offices. Such Buyer is a resident of that jurisdiction specified below its name and address on the Schedule of Buyers.

j. Title to Units. Such Buyer immediately prior to Closing will have good and marketable title to each of the Exchanged Securities owned by it, free and clear of any Liens. There are no preemptive, conversion, subscription or other rights, options, warrants or agreements granted or issued by, or binding upon, such Buyer for the purchase or acquisition of any of the Exchanged Securities. Upon delivery to the Company by such Buyer of the Exchanged Securities owned by it, good and marketable title to such Exchanged Securities (in the case of the Old Warrant, only with respect to 3,000,000 shares of Common Stock subject thereto) will be sold, assigned, conveyed, transferred and delivered to the Company, free and clear of all Liens.

k. No Conflict. Neither the execution and delivery of this Agreement or any Transaction Document by such Buyer nor the performance by such Buyer of the transactions contemplated hereby or thereby will, directly or indirectly, contravene, conflict with, or result in (with or without notice or lapse of time) a violation or breach of any of the Exchanged Securities owned by it, or give any Person the right (with or without notice or lapse of time) to declare a default or exercise any remedy under, or to accelerate the maturity or performance of, or to cancel, terminate, modify, withdraw or suspend any of the Exchanged Securities owned by it.

2A. MARQUIS REPRESENTATIONS AND WARRANTIES REGARDING NORTH TEXAS.

Other than with respect to the entities listed on Schedule 3(a), the Company does not directly or indirectly own any security or beneficial ownership interest, in any other Person (including through joint venture or partnership agreements) or have any interest in any other Person. Each of the Company and the Subsidiaries is a corporation, limited liability company, partnership or other entity and is duly organized or formed and validly existing in good standing under the laws of the jurisdiction in which it is incorporated or organized and has the requisite corporate, partnership, limited liability company or other organizational power and authority to own its properties and to carry on its business as now being conducted and as proposed to be conducted by the Company and the Subsidiaries. Each of the Company and the Subsidiaries is duly qualified to do business and is in good standing in every jurisdiction in which its ownership of property or the nature of the business conducted makes such qualification necessary, except to the extent that the failure to be so qualified or be in good standing could not have and could not be, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

To the extent that the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities that is permissible under applicable law.

b. Promptly after receipt by an Indemnitee under this Section 8 of notice of the commencement of any action or proceeding (including any governmental action or proceeding) involving any Indemnified Liabilities, such Indemnitee shall, if any claim for Indemnified Liabilities in respect thereof is to be made against the Company under this Section 8, deliver to the Company a written notice of the commencement thereof, and the Company shall have the right to participate in, and, to the extent the Company so desires, to assume control of the defense thereof with counsel mutually satisfactory to the Company and the Indemnitee, as the case may be. In any such proceeding, any Indemnitee may retain its own counsel, but, except as provided in the following sentence, the fees and expenses of that counsel will be at the expense of that Indemnitee, as the case may be, unless (i) the Company and the Indemnitee, as applicable, shall have mutually agreed to the retention of that counsel, (ii) the Company does not assume the defense of such proceeding in a timely manner or (iii) in the reasonable opinion of counsel retained by the Company, the representation by such counsel for the Indemnitee and the Company would be inappropriate due to actual or potential differing interests between such Indemnitee and any other party represented by such counsel in such proceeding. The Company shall pay reasonable fees for only one separate legal counsel (plus any local counsel) for the Investors, and such legal counsel shall be selected by Investors holding at least 2/3 in interest of the outstanding Sub Notes (or, if no Sub Notes are outstanding, of the outstanding Warrant). The Indemnitee shall cooperate fully with the Company in connection with any negotiation or defense of any such action by the Company and shall furnish to the Company all information reasonably available to the Indemnitee which relates to such action. The Company shall keep the Indemnitee fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. The Company shall not be liable for any settlement of any action, claim or proceeding effected without its prior written consent; provided, however, that the Company shall not unreasonably withhold, delay or condition its consent. The Company shall not, without the prior written consent of the Indemnitee, consent to entry of any judgment or enter into any settlement or other compromise with respect to any pending or threatened action or claim in respect of which indemnification or contribution may be or has been sought hereunder (whether or not the Indemnitee is an actual or potential party to such action or claim) which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnitee of a release from all liability in respect to such litigation and such settlement shall not include any admission as to fault on the part of the Indemnitee. Following indemnification as provided for hereunder, the Company shall be subrogated to all rights of the Indemnitee with respect to all third parties, firms or corporations relating to the matter for which indemnification has been made. The failure to deliver written notice to the Company within a reasonable time of the commencement of any such action shall not relieve such Company of any liability to the Indemnitee under this Section 8, except to the extent that the Company is prejudiced in its ability to defend such action.

c. The indemnification required by this Section 8 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or Indemnified Liabilities are incurred.

d. The indemnity agreements contained herein shall be in addition to (i) any cause of action or similar right of the Indemnitee against the Company or others, and (ii) any liabilities the Company may be subject to pursuant to the law.

9. GOVERNING LAW; MISCELLANEOUS.

a. Governing Law; Jurisdiction; Jury Trial. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the New York City, borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address for such notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof.

b. Counterparts. This Agreement and any amendments hereto may be executed and delivered in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original, but all of which taken together shall constitute one and the same agreement, and shall become effective when counterparts have been signed by each party hereto and delivered to the other parties hereto, it being understood that all parties need not sign the same counterpart. In the event that any signature to this Agreement or any amendment hereto is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof. At the request of any party each other party shall promptly re-execute an original form of this Agreement or any amendment hereto and deliver the same to the other party. No party hereto shall raise the use of a facsimile machine or e-mail delivery of a “.pdf” format data file to deliver a signature to this Agreement or any amendment hereto or the fact that such signature was transmitted or communicated through the use of a facsimile machine or e-mail delivery of a “.pdf” format data file as a defense to the formation or enforceability of a contract, and each party hereto forever waives any such defense.

c. Headings. The headings of this Agreement are for convenience of reference and shall not form part of, or affect the interpretation of, this Agreement.

d. Severability. If any provision of this Agreement shall be invalid or unenforceable in any jurisdiction, such invalidity or unenforceability shall not affect the validity or enforceability of the remainder of this Agreement in that jurisdiction or the validity or enforceability of any provision of this Agreement in any other jurisdiction.

e. Entire Agreement; Amendments.

Any such amendment shall bind all holders of the Notes and the Warrant. No such amendment shall be effective to the extent that it applies to less than all of the Notes or Warrant then outstanding.

or at such other address and/or facsimile number and/or to the attention of such other person as the recipient party has specified by written notice to the other party at least five (5) Business Days prior to the effectiveness of such change. Written confirmation of receipt (A) given by the recipient of such notice, consent, waiver or other communication, (B) mechanically or electronically generated by the sender’s facsimile machine containing the time, date, recipient facsimile number and an image of the first page of such transmission or (C) provided by a nationally recognized overnight delivery service shall be rebuttable evidence of personal service, receipt by facsimile or deposit with a nationally recognized overnight delivery service in accordance with clause (i), (ii) or (iii) above, respectively.

g. Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their respective successors and assigns, including any purchasers of the Securities. The Company shall not assign this Agreement or any rights or obligations hereunder without the prior written consent of the holders of at least two-thirds (2/3) of the aggregate principal of the Sub Notes then outstanding, including by merger or consolidation. Buyers may assign some or all of their rights hereunder without the consent of the Company; provided, however, that any such assignment shall not release a Buyer from its obligations hereunder unless such obligations are assumed by such assignee (as evidenced in writing) and the Company has consented to such assignment and assumption, which consent shall not be unreasonably withheld. Notwithstanding anything to the contrary contained in the Transaction Documents, Buyers shall be entitled to pledge the Securities in connection with a bona fide margin account or other loan or financing arrangement secured by the Securities.

h. No Third Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective permitted successors and assigns and, to the extent provided in Section 8 hereof, each Indemnitee, and is not for the benefit of, nor may any provision hereof be enforced by, any other Person.

i. Survival. Unless this Agreement is terminated under Section 9(k), the representations and warranties of the Company and Buyers contained in Sections 2 and 3, the agreements and covenants set forth in Sections 4, 5 and 9, and the indemnification and contribution provisions set forth in Section 8, shall survive the Closing. The Company acknowledges and agrees that the provisions of Section 15 of the Sub Notes shall survive the redemption, repayment or surrender of such Sub Notes.

j. Further Assurances. Each party shall do and perform, or cause to be done and performed, all such further acts and things, and shall execute and deliver all such other agreements, certificates, instruments and documents, as the other party may reasonably request in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated hereby.

k. Termination. In the event that the Closing shall not have occurred on or before the third Business Day following the date of this Agreement due to the Company’s or Buyers’ failure to satisfy the conditions set forth in Sections 6 and 7 above (and the nonbreaching party’s failure to waive such unsatisfied condition(s)), the nonbreaching party (i.e., the Company in the case of a breach by a Buyer, and any Buyer in the case of a breach by the Company) shall have the option to terminate this Agreement with respect to such breaching party at the close of business on such date without liability of any party to any other party; provided, however, that if this Agreement is terminated pursuant to this Section 9(k), the Company shall be obligated to pay each Buyer (so long as such Buyer is not a breaching party) its transaction fees and reimbursement amounts as set forth in Section 4(i) as if such Buyer had purchased the Sub Notes (and in the case of Marquis, the Warrant).

l. No Strict Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party.

m. Remedies. Buyers and each holder of the Securities shall have all rights and remedies set forth in the Transaction Documents and all rights and remedies that Buyers and holders have been granted at any time under any other agreement or contract and all of the rights that Buyers and holders have under any law. Any Person having any rights under any provision of this Agreement shall be entitled to enforce such rights specifically (without any requirement to post a bond or other security or prove actual damages, which requirements each of the parties waives to the fullest extent permitted by Law), to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law.

n. Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) the Transaction Documents, whenever a Buyer exercises a right, election, demand or option under a Transaction Document and the Company or any of the Subsidiaries does not timely perform its related obligations within the periods therein provided, then such Buyer may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights.

o. Payment Set Aside. To the extent that the Company or any of the Subsidiaries makes a payment or payments to a Buyer pursuant to this Agreement, the Sub Notes, the Guaranty or any other Transaction Document or a Buyer enforces or exercises its rights hereunder or thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company or any of the Subsidiaries, by a trustee, receiver or any other Person under any law (including any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

p. Transfer Agent Instructions. The Company shall issue irrevocable instructions to its transfer agent in the form attached hereto as Exhibit F (the “Irrevocable Transfer Agent Instructions”), and any subsequent transfer agent, to issue certificates or credit shares to the applicable balance accounts at DTC, registered in the name of each Buyer or its nominee(s), for Warrant Shares upon exercise of the Warrant or Option Shares upon exercise of the Investor Share Option (as applicable), in such amounts as specified from time to time by each Buyer to the Company. On or before November 14, 2008, the Company shall deliver to each Buyer a fully executed copy of the Irrevocable Transfer Agent Instructions (including execution by the Company’s transfer agent). The Company warrants that no instruction other than the Irrevocable Transfer Agent Instructions referred to in this Section 9(p) and stop transfer instructions to give effect to Section 2(g) will be given by the Company to its transfer agent and that the Securities shall otherwise be freely transferable on the books and records of the Company as and to the extent provided in this Agreement. If any Buyer provides the Company with an opinion of counsel, in a generally acceptable form, to the effect that a public sale, assignment or transfer of the Securities may be made without registration under the 1933 Act or such Buyer provides the Company with reasonable assurance that the Securities can be sold pursuant to Rule 144 without any restriction as to the number of securities acquired as of a particular date that can then be immediately sold, the Company shall permit the transfer and, in the case of the Warrant Shares or the Option Shares, promptly instruct its transfer agent to issue one or more certificates or credit shares to the applicable balance accounts at DTC in such name and in such denominations as specified by such Buyer and without any restrictive legend. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to each Buyer by vitiating the intent and purpose of the transactions contemplated hereby. Accordingly, the Company acknowledges that the remedy at law for a breach of its obligations under this Section 9(p) will be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section 9(p), that each Buyer shall be entitled, in addition to all other available remedies, to an injunctive order and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing economic loss and without any bond or other security being required.

q. Interpretative Matters. Unless the context otherwise requires, (a) all references to Sections, Schedules or Exhibits are to Sections, Schedules or Exhibits contained in or attached to this Agreement, (b) each accounting term not otherwise defined in this Agreement has the meaning assigned to it in accordance with GAAP, (c) words in the singular or plural include the singular and plural and pronouns stated in either the masculine, the feminine or neuter gender shall include the masculine, feminine and neuter, and (d) the use of the word “including” in this Agreement shall be by way of example rather than limitation. All references herein and in each of the other Transaction Documents to “dollars” or “$” shall mean the lawful money of the United States of America.

r. Independent Nature of the Buyers. The obligations of each Buyer hereunder are several and not joint with the obligations of any other Buyer, and no Buyer shall be responsible in any way for the performance of the obligations of any other Buyer hereunder. Each Buyer shall be responsible only for its own representations, warranties, agreements and covenants hereunder. The decision of each Buyer to acquire the Securities pursuant to this Agreement has been made by such Buyer independently of any other Buyer and independently of any information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Company or any of the Subsidiaries which may have been made or given by any other Buyer or by any agent or employee of any other Buyer, and no Buyer or any of its agents or employees shall have any liability to any other Buyer (or any other Person or entity) relating to or arising from any such information, materials, statements or opinions. Nothing contained herein, and no action taken by any Buyer pursuant hereto or thereto, shall be deemed to constitute the Buyers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Buyers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated hereby. Each Buyer shall be entitled to independently protect and enforce its rights, including the rights arising out of this Agreement, the Bridge Notes and the other Transaction Documents, and it shall not be necessary for any other Buyer to be joined as an additional party in any proceeding for such purpose.

s. Waiver of Old Warrant Anti-Dilution Provisions. Longview hereby waives any adjustment to the Warrant Exercise Price (as defined in the Old Warrant (and in the New Longview Warrant)), or to the number of shares of Common Stock issuable upon exercise of the Old Warrant (or of the New Longview Warrant), pursuant to Section 8 of the Old Warrant (or of the New Longview Warrant), solely to the extent that such adjustment would directly result from the Company’s issuance of the Warrant, the Warrant Shares, the Sub Notes, the Option Shares, the Warrants (as defined in the Securities Purchase Agreement), the Warrant Shares (as defined in the Securities Purchase Agreement), the Override Exchange Shares or the Conversion Shares, all in accordance with the terms and conditions set forth in this Agreement, the Securities Purchase Agreement, the Warrants and the Sub Notes.

IN WITNESS WHEREOF, Buyers and the Company have caused this Securities Exchange Agreement to be duly executed as of the date first written above.
