6.4 Reporting Requirements. The Company will file with the SEC all reports required to be filed pursuant to the Exchange Act on a timely basis taking into account any and all extensions granted or permitted by the SEC, and refrain from terminating its status as an issuer required by the Exchange Act to file reports thereunder even if the Exchange Act or the rules or regulations thereunder would permit such termination.

(a) directly or indirectly declare or pay any dividends, other than (i) dividends with respect to its preferred stock, and (ii) as to the Subsidiaries only, dividends payable to the Company;

(b) liquidate, dissolve or effect a material reorganization; provided, that as to any Subsidiary, such Subsidiary may liquidate, dissolve or effect a material reorganization without need of obtaining the prior written consent of the Purchaser if such Subsidiary shall transfer all of its assets and liabilities either to the Company or to another Subsidiary that is a party to the Master Security Agreement, the Stock Pledge Agreement and the Subsidiary Guaranty; provided further that, notwithstanding the foregoing, a Core Subsidiary (as defined in the Master Security Agreement) shall not be permitted to transfer any of its assets to a Non-Core Subsidiary (as defined in the Master Security Agreement) without the consent of the Purchaser;

(c) become subject to (including, without limitation, by way of amendment to or modification of) any agreement or instrument which by its terms would (under any circumstances) restrict the Company’s right to perform the provisions of this Agreement or any Related Agreement to which the Company is a party, or would restrict any Subsidiary from performing its obligations under the Guaranty or any other Related Agreement to which such Subsidiary is a party;

(d) materially alter or change the scope of the business of the Company and its Subsidiaries taken as a whole;

The Company agrees to cooperate with the Purchaser in connection with all resales pursuant to Rule 144(d) and Rule 144(k) and provide legal opinions necessary to allow such resales provided the Company and its counsel receive reasonably requested representations from the selling Purchaser and broker, if any.

The Company will provide, at the Company’s expense, such other legal opinions in the future as are reasonably necessary for the conversion of the Convertible Note and exercise of the Warrant.

7. Covenants of the Purchaser.

The Purchaser covenants and agrees with the Company as follows:

7.1 Confidentiality.

7.3 No Shorting.

Purchaser may assign the Notes (or any portion thereof) or the Warrant, provided that the assignees of either Note or the Warrant agree in writing to be bound by the terms of and perform all of Purchaser’s obligations under this Agreement and the Related Agreements and such assignee provides evidence reasonably satisfactory to the Company demonstrating compliance with applicable securities laws, which shall include, without limitation, written certification from the assignee of its sophistication and status as an accredited investor under Regulation D of the Securities Act and a legal opinion from the transferor’s counsel that such transfer is exempt from the registration requirements of applicable securities laws. Purchaser or any assignee may not assign any of its rights or remedies under the Master Security Agreement, the Stock Pledge Agreement or the Subsidiary Guaranty to any person or entity other than a permitted assignee of either Note, and Purchaser may not assign any of its rights under the Registration Rights Agreement to any person or entity other than a permitted assignee of either Note or the Warrant. Purchaser or any assignee of either Note or the Warrant may not assign its rights hereunder or thereunder to a Competitor (as defined herein) of the Company, unless an Event of Default (as defined in either Note) has occurred and is continuing.

A “Competitor” shall mean any business entity that (i) is primarily engaged in providing similar products or services as the Company and from which such products and services the Company derived material revenues for the prior twelve (12) months, and (ii) does business in any U.S. state in which the Company has an established business. In the event there is more than one holder of the rights and obligations under the Note, then an agent for such holders shall be appointed by the then holder(s) of the majority principal amount outstanding under the Note for the sole purpose of dealing with the Company in connection with administrative matters relating to this Agreement and the Related Agreements, including in requesting waivers and consents. Unless such agent has authority from the holders to grant any such waiver, consent or to make any amendments to this Agreement, the Notes, the Subsidiary Guaranty, the Stock Pledge Agreement or the Master Security Agreement without the consent of the holders, all such grants of waivers, consents or amendments shall be made by such agent acting upon the consent of the holders of a majority in principal amount then outstanding except for (i) any modifications in the principal amount, rate of interest or fees payable under the Notes or any Related Agreement, (ii) postponements in any fixed payment date, (iii) releases or discharges of the Company or any Subsidiary of any obligation or releases of any collateral except as provided in this Agreement or the Related Agreements or (iv) any amendment to this Section 9.4, which shall be approved by all holders affected thereby.

9.8 Delays or Omissions. It is agreed that no delay or omission to exercise any right, power or remedy accruing to any party, upon any breach, default or noncompliance by another party under this Agreement or the Related Agreements, shall impair any such right, power or remedy, nor shall it be construed to be a waiver of any such breach, default or noncompliance, or any acquiescence therein, or of or in any similar breach, default or noncompliance thereafter occurring. All remedies, either under this Agreement, the Notes or the

Related Agreements, by law or otherwise afforded to any party, shall be cumulative and not alternative.

9.9 Notices. All notices required or permitted hereunder shall be in writing and shall be deemed effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed facsimile if sent during normal business hours of the recipient, if not, then on the next business day, (c) three (3) business days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt.

In the event of a settlement, each party shall bear its own fees, costs and expenses unless otherwise directed by a court of competent jurisdiction.

9.11 Titles and Subtitles. The titles of the sections and subsections of the Agreement are for convenience of reference only and are not to be considered in construing this Agreement.

9.12 Facsimile Signatures; Counterparts.

Any party delivering an executed counterpart of this Agreement by facsimile transmission shall deliver an original of such counterpart to the other party hereto within two (2) business days; provided, however, that the failure to so deliver any original counterpart shall not affect the validity or enforceability of this Agreement as against such party.

9.13 Broker’s Fees. Except as set forth on Schedule 9.13 hereof, Each party hereto represents and warrants that no agent, broker, investment banker, person or firm acting on behalf of or under the authority of such party hereto is or will be entitled to any broker’s or finder’s fee or any other commission directly or indirectly in connection with the transactions contemplated herein.
