have been no “reportable events” (as such term is defined in section 4043 of ERISA) with respect to any multiemployer plan that could result in the termination of such multiemployer plan and give rise to a liability of the Company or any ERISA Affiliate in respect thereof except for such “reportable events” that, in the aggregate for all such “reportable events,” would not reasonably be expected to have a Material Adverse Effect. Neither the Company nor any of its Subsidiaries has incurred or expects to incur liability under Sections 412 or 4971 of the Code, including the regulations and published interpretations thereunder; and each “pension plan” for which the Company would have any liability that is intended to be qualified under Section 401(a) of the Code has been determined by the Internal Revenue Service to be so qualified and nothing has occurred, whether by action or by failure to act, which could reasonably be expected to cause the loss of such qualification.

3.21 No Undisclosed Liabilities. There are no material liabilities of the Company or any of its Subsidiaries, other than liabilities incurred in the ordinary course of business consistent with past practice since September 30, 2005, or which in the aggregate would not reasonably be expected to result in a Material Adverse Effect.

3.31 Securities Laws. Subject to the accuracy of the Purchasers’ representations and warranties set forth in Section 4 below and an Investor Questionnaire executed and delivered by each Purchaser to the Company, such Investor Questionnaire in the form attached hereto as Exhibit A, the offer, sale and issuance of the Shares and the Warrants, and issuance of Warrant Shares, as provided in this Agreement and the Warrants, is and is intended to be (a) exempt from the registration requirements of the Securities Act pursuant to Section 4(2) thereof and Regulation D promulgated thereunder, and (b) exempt from registration or qualification requirements of applicable state securities laws (together, the “Securities Laws Exemptions”). Neither the Company or its Subsidiaries nor anyone acting on its or their behalf has taken any action that would cause the loss of such exemptions.

3.32 No Integrated Offering. Neither the Company, nor any Affiliate of the Company, nor any Person acting on its or their behalf has, directly or indirectly, engaged in any form of general solicitation or general advertising with respect to any security or made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would cause the offering or issuance of the Shares, the Warrants or any Warrant Shares pursuant to this Agreement and the Warrants to be integrated with prior offerings by the Company for purposes of the Securities Act which would cause the exemptions from SEC registration upon which the Company is relying for the offering or issuance of the Shares, the Warrants or any Warrant Shares pursuant to this Agreement to be unavailable, or would cause any applicable state securities laws exemptions or any applicable stockholder approval provisions exemptions, including, without limitation, under the rules and regulations of any national securities exchange or automated quotation system on which any of the securities of the Company are listed or designated to be unavailable, nor will the Company take any action or steps that would cause the offering or issuance of the Shares, the Warrants or any Warrant Shares pursuant to this Agreement and the Warrants to be integrated with other offerings.

3.33 Interested Stockholder. To the knowledge of the Company, each Purchaser is not an “interested stockholder” (as defined in Nevada Revised Statute 78.423) of the Company as of the Closing Date, nor will a Purchaser be deemed an “interested stockholder” as a result of the consummation of the transactions contemplated herein, and the restrictions on “combinations” (as defined in Nevada Revised Statute 78.416) set forth in Nevada Revised Statute 78.438 do not apply to the transactions contemplated hereby. The Board of Directors of the Company has approved the issuance to each Purchaser of the Warrant Shares issuable upon exercise of the Warrants, and the restrictions on “combinations” set forth in Nevada Revised Statute 78.438 will not apply to any exercise of the Warrants by a Purchaser.

3.34 Application of Takeover Protections. The Company and the Board have taken all necessary action, if any, in order to render inapplicable any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or other similar anti-takeover provision under the Company’s charter documents or the laws of its state of incorporation that is or could become applicable to the Purchasers as a result of the Purchasers and the Company fulfilling their obligations or exercising their rights under this Agreement, the Warrants and the Registration Rights Agreement, including without limitation the Company’s issuance of the Shares and the Purchasers’ ownership of the Shares.

3.35 Solvency. Based on the consolidated financial condition of the Company and its Subsidiaries as of the date hereof, (i) the fair saleable value of the Company’s assets exceeds the amount that will be required to be paid on or in respect of the Company’s existing debts and other liabilities (including known and contingent liabilities) as they mature; (ii) the Company’s assets do not constitute unreasonably small capital to carry on its business for the current fiscal year as now conducted and as proposed to be conducted, including its capital needs taking into account the particular capital requirements of the business conducted by the Company, projected capital requirements and capital availability thereof; and (iii) the current cash flow of the Company, together with the proceeds the Company would receive were it to liquidate all of its assets, after taking into account all anticipated uses of the cash, would be sufficient to pay all amounts on or in respect of its debts when such amounts are required to be paid. The Company has no present intention to incur debts beyond its ability to pay such debts as they mature (taking into account the timing and amounts of cash to be payable on or in respect of its debt).

3.36 Disclosure. Neither this Agreement, the Registration Rights Agreement, the Warrants, the Offering Memorandum, nor any other statements or certificates made or delivered in connection herewith or therewith, when taken as a whole, contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements contained herein or therein not misleading in light of the circumstances under which they were made.

4. Representations and Warranties of the Purchasers. In order to induce the Company to enter into this Agreement and to sell the Shares and the Warrants, each Purchaser represents and warrants, severally (as to such Purchaser only) and not jointly, as of the Closing Date, all of which shall survive the execution and delivery of this Agreement and the purchase of the Shares:

4.1 Authorization. All corporate, partnership or limited liability company action on the part of such Purchaser necessary for the authorization, execution, delivery and performance of this Agreement and the Registration Rights Agreement, and the consummation of the transactions contemplated herein and therein, has been taken. When executed and delivered by such Purchaser, each of this Agreement and the Registration Rights Agreement will constitute the legal, valid and binding obligation of such Purchaser, enforceable against such Purchaser in accordance with its terms, except as such may be limited by bankruptcy, insolvency, reorganization or other laws affecting creditors’ rights generally and by general equitable principles. Such Purchaser has all requisite corporate, partnership or limited liability company power and authority to enter into each of this Agreement and the Registration Rights Agreement, and to carry out and perform its obligations under the terms hereof and thereof.

4.2 Purchase Entirely for Own Account. Such Purchaser is acquiring the Shares and Warrants for its own account and not for resale or with a view to any resale, fractionalization, division, or distribution thereof in violation of the Securities Act. Such Purchaser has no contract, undertaking, agreement, understanding or arrangement with any person to sell, transfer, or pledge to any person any part or all of the Shares, Warrants or Warrant Shares which such Purchaser is acquiring, or any interest therein, and has no present plans to enter into the same (other than margin security agreements with a registered broker-dealer in the ordinary course of business). The Shares and Warrants were offered or sold to such Purchaser by means of a direct solicitation by the Company and one or both of the Placement Agents.

4.3 Investor Status; Etc. Such Purchaser certifies and represents to the Company that (i) it is an “accredited investor” as defined in Rule 501 of Regulation D promulgated under the Securities Act and was not organized for the purpose of acquiring any of the Shares or the Warrants and (ii) such Purchaser’s Investor Questionnaire is complete and correct. Such Purchaser’s financial condition is such that it is able to bear the risk of holding the Shares for an indefinite period of time and the risk of loss of its entire investment. Such Purchaser has sufficient knowledge and experience in investing in companies similar to the Company so as to be able to evaluate the risks and merits of its investment in the Company. Such Purchaser fully understands that the Shares, Warrants and Warrant Shares are speculative investments which involve a high degree of risk of loss of such Purchaser’s entire investment. No Person, other than the Company, the placement agent or their authorized representatives, has offered the Shares and Warrants to such Purchaser.

4.4 Securities Not Registered. Such Purchaser understands that none of the Shares, the Warrants nor the Warrant Shares have been registered under the Securities Act, by reason of their issuance by the Company in a transaction exempt from the registration requirements of the Securities Act, and that each of such securities must continue to be held by such Purchaser unless a subsequent disposition thereof is registered under the Securities Act or is exempt from such registration. Such Purchaser understands that the exemptions from registration

afforded by Rule 144 (the provisions of which are known to it) promulgated under the Securities Act depend on the satisfaction of various conditions, and that, if applicable, Rule 144 may afford the basis for sales only in limited amounts. Such Purchaser has had an opportunity to ask questions of and receive answers from the management and authorized representatives of the Company, and to review any other relevant documents and records concerning the business of the Company and the terms and conditions of this investment, and that any such questions have been answered to such Purchaser’s full satisfaction. Such Purchaser understands that no federal or state agency has passed upon or made any recommendation or endorsement of an investment in the Shares or Warrants.

4.5 No Violation. Neither the execution, delivery and performance by such Purchaser of this Agreement and the Registration Rights Agreement nor compliance with the terms and provisions hereof and thereof by such Purchaser (a) will contravene any applicable provision of any law, statute, rule, regulation, order, writ, injunction or decree of any court or Governmental Authority, except as would not have a material adverse effect on such Purchaser’s ability to consummate the transactions contemplated hereby; or (b) will violate any provision of the organizational documents of such Purchaser, except as would not have a material adverse effect on such Purchaser’s ability to consummate the transactions contemplated hereby.

4.6 Brokers. Such Purchaser has not retained, utilized or been represented by any broker or finder in connection with the transactions contemplated by this Agreement.

All consents, approvals, orders and authorizations required on the part of such Purchaser in connection with the execution, delivery or performance of this Agreement and the consummation of the transactions contemplated herein have been obtained and are effective as of the date hereof.

4.8 Disclosure of Information. Such Purchaser has relied on its own examination of the Company, including the merits and risks involved in making an investment decision with respect to the Shares and Warrants. Such Purchaser believes it has received all the information it considers necessary or appropriate for deciding whether to purchase the Shares and Warrants. Such Purchaser further acknowledges that it has reviewed the Offering Memorandum and that it has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of the Shares and Warrants and the business, properties, prospects and financial condition of the Company. The foregoing does not, however, limit or modify the representations and warranties of the Company set forth in Article III of this Agreement or the rights of the Purchasers to rely thereon.

4.9 Short Sales and Confidentiality Prior to The Date Hereof. During the last thirty (30) days prior to the date hereof, neither such Purchaser nor any Affiliate of such Purchaser, foreign or domestic, has, directly or indirectly, effected or agreed to effect any Short Sale, whether or not against the box, established any “put equivalent position” (as defined in Rule 16a-1(h) under the Exchange Act) with respect to the Common Stock, borrowed or pre-borrowed any shares of Common Stock, or granted any other right (including, without limitation, any put or call option) with respect to the Common Stock or with respect to any security that includes, relates to or derived any significant part of its value from the Common Stock or otherwise sought to hedge its position in the Securities (each, a “Prohibited Transaction”).

Notwithstanding the foregoing, (i) in the case of a Purchaser and/or its Affiliates that is, individually or collectively, a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Purchaser’s or Affiliates assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of such Purchaser’s or Affiliates assets, the representation set forth above shall only apply with respect to the portion of assets managed by the portfolio managers that have knowledge about the financing transaction contemplated by this Agreement and (ii) in the case of LB I Group Inc., the representation set forth in this Section 4.9 shall only apply with respect to the Equity Strategies Group - Opportunity Fund of Xxxxxx Brothers Holdings Inc. and not to any other persons, affiliates or affiliated or associated business units thereof. Such Purchaser has maintained the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction) other than to other Persons that are a party to this Agreement.

Such Purchaser is not itself, or is not otherwise an affiliate of, a broker-dealer registered pursuant to Section 15 of the Exchange Act; provided, however, that if such Purchaser is itself, or is otherwise an affiliate of, a broker-dealer, then such Purchaser, at the time of purchase of the Shares, did not have any direct or indirect agreements or understandings with any Person to distribute the Shares. For purposes of the preceding sentence, an affiliate of a broker-dealer is any Person that, directly or indirectly, through one or more intermediaries, controls, is controlled by, or is under common control with, a broker-dealer, and does not include any individuals employed by such broker-dealer or its affiliates.

exemption from registration under the Securities Act (including sales permitted pursuant to Rule 144) and applicable state securities laws, so long as the transferee (other than in sales permitted pursuant to Rule 144) agrees in a written instrument in form and substance reasonably satisfactory to the Company to be bound by the terms and provisions of this Agreement as if, and to the fullest extent as, such Purchaser). If the Company requests an opinion of counsel for such transferor that the proposed transfer may be effected without registration of such Shares, the Warrants or the Warrant Shares under the Securities Act (including sales permitted pursuant to Rule 144), such transferor shall not be entitled to effect such transfer unless and until the Company receives such an opinion of counsel (which counsel and opinion shall each be reasonably satisfactory to the Company).

(b) Prior to the earliest to occur of (A) the termination of this Agreement, (B) the Effective Date or (C) the Mandatory Effective Date, such Purchaser shall not, and shall cause its Affiliates not to, engage, directly or indirectly, in (i) a Prohibited Transaction or (ii) any sale, assignment, pledge, hypothecation, put, call, or other transfer of any of the shares of Common Stock, warrants or other securities of the Company acquired hereunder (except as collateral security for a margin agreement with a registered broker-dealer entered into in the ordinary course of business). Notwithstanding the foregoing, (x) in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Purchaser’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of such Purchaser’s assets, the covenant set forth above shall only apply with respect to the portion of assets managed by the portfolio managers that have knowledge about the financing transaction contemplated by this Agreement and (y) in the case of LB I Group Inc., this Section 6.1(b) shall only apply with respect to the Equity Strategies Group - Opportunity Fund of Xxxxxx Brothers Holdings Inc. and not to any other persons, affiliates or affiliated or associated business units thereof. Each Purchaser further understands and acknowledges severally (as to itself only) and not jointly that the Staff of the SEC has publicly stated the position in Item 65, Section A, of the Manual of Publicly Available Telephone Interpretations, dated July 1997, that securities underlying a short position are deemed to be sold at the time such short position is established and, therefore, according to the SEC, the use by a Purchaser of Shares or Warrant Shares to cover a short position is a violation of Section 5 of the Securities Act unless such Shares or Warrant Shares, as the case may be, are not restricted under the Securities Act at the time such short position is established.

(c) Any transfer or purported transfer of the Shares in violation of this Section 6.1 or Section 6.2 shall be void. The Company shall not register any transfer of the Shares in violation of this Section 6.1 or Section 6.2. The Company may, and may instruct any transfer agent for the Company, to place such stop transfer orders as may be required on the transfer books of the Company in order to ensure compliance with the provisions of this Section 6.1 and Section 6.2.

6.2 Legends.

(a) To the extent applicable, each certificate or other document evidencing the Shares, the Warrants or the Warrant Shares shall be endorsed with the legend set forth below, and each Purchaser covenants that, except to the extent such restrictions are waived by the

Company, it shall not transfer the securities represented by any such certificate without complying with the restrictions on transfer described in this Agreement and the legends endorsed on such certificate:

[NEITHER] THIS SECURITY [NOR THE SECURITIES INTO WHICH THIS SECURITY IS [EXERCISABLE] [CONVERTIBLE]] HAS BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY. IN ADDITION, THE TRANSFER HEREOF IS SUBJECT TO VARIOUS AGREEMENTS CONTAINED IN A SECURITIES PURCHASE AGREEMENT DATED OCTOBER 19, 2006. A COPY OF SUCH AGREEMENT WILL BE PROVIDED TO THE HOLDER UPON REQUEST. THIS SECURITY AND THE SECURITIES ISSUABLE UPON [EXERCISE] [CONVERSION] OF THIS SECURITY MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN SECURED BY SUCH SECURITIES.

The Company acknowledges and agrees that a Purchaser may from time to time pledge pursuant to a bona fide margin agreement with a registered broker-dealer or grant a security interest in some or all of the securities to a financial institution that is an “accredited investor” as defined in Rule 501(a) under the Securities Act and who agrees to be bound by the provisions of this Agreement and the Registration Rights Agreement and, if required under the terms of such arrangement, such Purchaser may transfer pledged or secured securities to the pledgees or secured parties. Such a pledge or transfer would not be subject to approval of the Company and no legal opinion of legal counsel of the pledgee, secured party or pledgor shall be required in connection therewith. Further, no notice shall be required of such pledge. At the appropriate Purchaser’s expense, the Company will execute and deliver such reasonable documentation as a pledgee or secured party of Company securities may reasonably request in connection with a pledge or transfer of the securities, including, if the securities are subject to registration pursuant to the Registration Rights Agreement, the preparation and filing of any required prospectus supplement under Rule 424(b)(3) under the Securities Act or other applicable provision of the Securities Act to appropriately amend the list of selling stockholders thereunder.

(b) The Company agrees, upon a Purchaser’s reasonable request, to reissue certificates representing any of the Shares or Warrant Shares, without the legend set forth in Section 6.2(a) above (i) when a registration statement (including the Mandatory Registration Statement to be filed pursuant to the Registration Rights Agreement) providing for the resale of such Shares and Warrant Shares is declared effective under the Securities Act, (ii) following any sale of such Shares or Warrant Shares pursuant to Rule 144 (assuming the transferor is not an Affiliate of the Company), (iii) if such Shares or Warrant Shares are eligible for sale under Rule

144(k) (to the extent that such Purchaser provides a certification or legal opinion to the Company to that effect), or (iv) if such legend is not required under applicable requirements of the Securities Act (including controlling judicial interpretations and pronouncements issued by the SEC). Following the Effective Date or at such earlier time as a legend is no longer required for the Shares or the Warrant Shares, the Company will, promptly following the delivery by a Purchaser to the Company or the Company’s transfer agent of a legended certificate representing such Shares or Warrant Shares, deliver or cause to be delivered to such Purchaser a certificate representing such Shares or Warrant Shares that is free from all restrictive legends. The restrictions on transfer contained in this Section 6.1 shall be in addition to, and not by way of limitation of, any other restrictions on transfer contained in any other section of this Agreement. Whenever a certificate representing the Shares or Warrant Shares is required to be issued to a Purchaser without a legend, in lieu of delivering physical certificates representing the Shares or Warrant Shares, provided the Company’s transfer agent is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer program, the Company shall cause its transfer agent to electronically transmit the Shares or Warrant Shares to a Purchaser in accordance with any written instructions provided by such Purchaser by crediting the account of such Purchaser’s Prime Broker with DTC through its Deposit Withdrawal Agent Commission (“DWAC”) system (to the extent not inconsistent with any provisions of this Agreement).

(c) Each Purchaser, severally and not jointly with the other Purchasers, agrees that the removal of the restrictive legend from certificates representing securities as set forth in this Section 6.2 is predicated upon the Company’s reliance that the Purchaser will sell any securities pursuant to either the registration requirements of the Securities Act, including any applicable prospectus delivery requirements, or an exemption therefrom, and that if securities are sold pursuant to a registration statement, they will be sold in compliance with the plan of distribution set forth therein.

6.3 Publicity. Except to the extent required by applicable laws, rules, regulations or stock exchange requirements, the Company, its Subsidiaries and their Affiliates shall not, without the written consent of the Majority Purchasers, make any public announcement or issue any press release with respect to the transactions contemplated by this Agreement; provided that the Company, each of its Subsidiaries and their respective Affiliates shall not, without the prior written consent of the Purchaser, disclose or publish the name of such Purchaser in any such press release or public announcement. Except to the extent required by applicable laws, rules, regulations or stock exchange requirements, the Purchasers and their Affiliates shall not, without the written consent of the Company make any public announcement or issue any press release with respect to the transactions contemplated by this Agreement. In no event will either (i) the Company, its Subsidiaries or any of their Affiliates or (ii) any Purchaser or any of its Affiliates make any public announcement or issue any press release with respect to the transactions contemplated by this Agreement without consulting with the Company, on the one hand, and Tejas Securities Group, Inc. and RBC Capital Markets, as co-placement agents, on the other hand, to the extent possible, as to the content of such public announcement or press release. Notwithstanding the foregoing, the parties agree that the Company shall issue a press release in the form of Exhibit F hereto promptly following (and in no event more than 24 hours after) the Closing and, on or before 9:00 a.m., New York time, on the first trading day following the Closing Date, the Company shall file a Current Report on Form 8-K describing the terms of

the transactions contemplated by this Agreement, the Warrants and the Registration Rights Agreement in the form required by the Exchange Act, and attaching the material transaction documents (including, without limitation, this Agreement (and all schedules to this Agreement) and the Registration Rights Agreement) as exhibits to such filing (including all attachments, the “8-K Filing”). From and after the filing of the 8-K Filing with the SEC, the Company shall use commercially reasonable efforts to assure that, and shall cause each of its Subsidiaries and each of their respective officers, directors, employees and agents to use commercially reasonable efforts to assure that, no Purchaser shall be in possession of any material, nonpublic information received from the Company, any of its Subsidiaries or any of its respective officers, directors, employees or agents, that is not disclosed in the 8-K Filing. The Company shall not, and shall cause each of its Subsidiaries and each of their respective officers, directors, employees and agents, not to, provide any Purchaser with any material nonpublic information regarding the Company or any of its Subsidiaries from and after the filing of the 8-K Filing with the SEC without the express written consent of such Purchaser; provided that the Company shall not be responsible for any information obtained by any Purchaser or any Inspector (as defined in the Registration Rights Agreement) as a result of such Purchaser’s exercise of its inspection rights under the Registration Rights Agreement; and provided further that in the event the Company or any of its Subsidiaries provides any information to a Purchaser under the Registration Rights Agreement and the Company reasonably believes that such information represents material nonpublic information, the Company (a) shall prior to such disclosure to any Purchaser notify such Purchaser of such belief and shall not provide such information to any Purchaser which does not expressly consent to receive such information and (b) to the extent any Purchaser determines not to receive such information, the Company shall be deemed not to be in breach of the original obligation to provide such information. In the event of a breach of the foregoing covenant by the Company, any of its Subsidiaries, or any of its or their respective officers, directors, employees and agents, in addition to any other remedy provided herein or in the Registration Rights Agreement, a Purchaser shall have the right to make a public disclosure, in the form of a press release, public advertisement or otherwise, of such material non-public information without the prior approval by the Company, its Subsidiaries, or any of its or their respective officers, directors, employees or agents; provided that the Purchaser will provide to the Company two (2) Business Days’ advance notice prior to such disclosure, and shall refrain from making such disclosure if the Company makes such disclosure during such two-day period. No Purchaser shall have any liability to the Company, its Subsidiaries, or any of its or their respective officers, directors, employees, shareholders or agents for any such disclosure made in compliance with this Section 6.3.

6.4 Use of Proceeds. The Company covenants and agrees that the proceeds from the sale of the Shares shall be used by the Company for the purposes described in the Offering Memorandum.

6.5 Integration. The Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Shares or Warrants in a manner that would require the registration under the Securities Act of the sale of the Shares to the Purchasers.

6.6 Reservation of Common Stock for Issuance; Listing of Shares. The Company agrees to reserve from its duly authorized capital stock the total number of shares of

Common Stock issuable upon execution of this Agreement and exercise of the Warrants. The Company agrees that at any time while its shares of Common Stock are listed on NASDAQ or any other securities exchange, that it will use commercially reasonable efforts to promptly list and qualify the Shares and Warrant Shares for trading on NASDAQ or such other securities exchange.

6.7 Actions with respect to Securities Laws Exemptions. Neither the Company nor anyone acting on its behalf shall take any action that would cause the loss of any Securities Laws Exemptions.

6.8 Restrictions on Certain Stock Issuances or Registrations. The Company agrees that prior to the effectiveness of the Mandatory Registration Statement (as defined in the Registration Rights Agreement), the Company shall not (i) issue any shares of Common Stock, or securities convertible into or exercisable for shares of Common Stock, that could be eligible for sale without restriction under the Securities Act prior to the effectiveness of the Mandatory Registration Statement (as defined in the Registration Rights Agreement), or (ii) grant any registration rights after the date hereof to any other Person that would entitle such Person to have the sale of securities held by such Person registered under the Securities Act by the Company under a registration statement that is declared effective prior to the effectiveness of the Mandatory Registration Statement, provided, that this Section 6.8 shall not be deemed to restrict the ability of the Company to (a) issue shares of Common Stock upon the exercise or conversion of any options, warrants, convertible debt instruments or other contingent securities outstanding on the date hereof or (b) issue shares of Common Stock, options or warrants to employees, directors or consultants of the Company.

6.9 Listing. After the Closing Date, the Company shall use commercially reasonable efforts to have the Shares and Warrant Shares listed on the Nasdaq Capital Market.

6.10 Equal Treatment of Purchasers. No consideration shall be offered or paid to any person to amend or consent to a waiver or modification of any provision of this Agreement, the Warrants or the Registration Rights Agreement unless the same consideration is also offered to all of the parties to this Agreement, the Warrants and the Registration Rights Agreement. For clarification purposes, this provision constitutes a separate right granted to each Purchaser by the Company and negotiated separately by each Purchaser, and is intended to treat the Purchasers as a class and shall not in any way be construed as the Purchasers acting in concert or as a group with respect to the purchase, disposition or voting of the Shares or otherwise.

7. Indemnification.

7.1 By the Company. The Company, without limitation as to time, agrees to indemnify, defend and hold harmless each Purchaser and its Affiliates and their respective officers, directors, agents, employees, subsidiaries, partners, members, investment advisers and controlling persons (collectively, the “Purchaser Indemnitees”) to the fullest extent permitted by law from and against any and all claims, losses, liabilities, damages, deficiencies, judgments, assessments, fines, settlements, costs or expenses (including interest, penalties and reasonable fees, disbursements and other charges of counsel) (collectively, “Losses”) based upon, arising out of or otherwise in respect of or relating to any breach by the Company of any representation,

warranty, covenant or agreement of the Company contained in this Agreement, the Warrants or in the Registration Rights Agreement.
