               (2) All of the licenses and sublicenses and consent, royalty or other agreements concerning Intellectual Property which are necessary for the conduct of Company’s and each of its Subsidiaries’ respective businesses as currently conducted or as currently proposed to be conducted to which the Company or any Subsidiary is a party or by which any of their assets are bound (other than generally commercially available, non-custom, off-the-shelf software application programs having a retail acquisition price of less than $10,000 per license) (collectively, “License Agreements”) are valid and binding obligations of the Company or its Subsidiaries that are parties thereto and, to the Company’s knowledge, the other parties thereto, enforceable in accordance with their terms, except to the extent that enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or other similar laws affecting the enforcement of creditors’ rights generally, and neither the Company nor any of its Subsidiaries nor, to the Company’s knowledge, any other party thereto, is in material violation or breach of any such License Agreement, and no action or failure to act by the Company or any of its Subsidiaries constitutes (with or without due notice or lapse of time or both) a material default by the Company or any of its Subsidiaries thereunder.

               (3) The Company and its Subsidiaries own or have the valid right to use all of the Intellectual Property necessary for the conduct of the Company’s and each of its Subsidiaries’ businesses substantially as currently conducted or as currently proposed to be

-11-

conducted and for the ownership, maintenance and operation of the Company’s and its Subsidiaries’ properties and assets.

               (4) Except as set forth on Schedule 2(o), all Intellectual Property owned by the Company and its Subsidiaries that is necessary for the conduct of the Company’s and each of its Subsidiaries’ respective businesses as currently conducted or as currently proposed to be conducted is valid and enforceable and owned by them free and clear of all liens, encumbrances, adverse claims or obligations to license all such owned Intellectual Property, other than licenses entered into in the ordinary course of the Company’s and its Subsidiaries’ businesses. The Company and its Subsidiaries have a valid and enforceable right to use all other Intellectual Property that is necessary for the conduct of the Company’s and each of its Subsidiaries’ respective businesses as currently conducted or as currently proposed to be conducted. The Company and its Subsidiaries have the right to use all of the owned and licensed Intellectual Property which is necessary for the conduct of Company’s and each of its Subsidiaries’ respective businesses as currently conducted or as currently proposed to be conducted in all jurisdictions in which they conduct their businesses.

               (5) The Company and each of its Subsidiaries have taken reasonable steps to maintain, police and protect the Intellectual Property which it owns and which is necessary for the conduct of Company’s and each of its Subsidiaries’ respective businesses as currently conducted or as currently proposed to be conducted, including the execution of appropriate confidentiality agreements and intellectual property and work product assignments and releases. The conduct of the Company’s and its Subsidiaries’ businesses as currently conducted does not infringe or otherwise impair or conflict with (collectively, “Infringe” or “Infringement”) any Intellectual Property rights of any third party, and, to the Company’s knowledge, the Intellectual Property rights of the Company and its Subsidiaries that are necessary for the conduct of Company’s and each of its Subsidiaries’ respective businesses as currently conducted or as currently proposed to be conducted are not being infringed by any third party, except to the extent such Infringements do not have a Material Adverse Effect. Except as disclosed in the SEC Filings, there is no litigation or order pending or outstanding or, to the Company’s knowledge, threatened or imminent, that seeks to limit or challenge or that concerns the ownership, use, validity or enforceability of any Intellectual Property of the Company and its Subsidiaries and the Company’s and its Subsidiaries’ use of any Intellectual Property owned by a third party. Except as Disclosed in the SEC Filings, neither the Company nor any of the Subsidiaries has entered into any consent agreement, indemnification agreement, forbearance to sue or settlement agreement with respect to the validity of the Company’s or its Subsidiaries’ ownership or right to use its Intellectual Property and, to the best knowledge of the Company, there is no reasonable basis for any such claim to be successful.

               (6) The consummation of the transactions contemplated hereby will not result in the alteration, loss, impairment of or restriction on the Company’s or any of its Subsidiaries’ ownership or right to use any of the Intellectual Property (including, without limitation, property used pursuant to License Agreements) which is necessary for the conduct of Company’s and each of its Subsidiaries’ respective businesses as currently conducted or as currently proposed to be conducted.

          (q) Litigation. Except as disclosed in the SEC Filings and Schedule 2(q), there are no pending or, to the knowledge of the Company, threatened actions, suits, proceedings, inquiries or investigations against or affecting the Company, its Subsidiaries or any of its or their properties or their respective directors or officers in their capacities as such, except for actions, suits, proceedings, inquiries or investigations which could not reasonably be expected to have a Material Adverse Effect. To the best knowledge of the Company, after reasonable investigation, there are no facts which, if known by a potential claimant or Governmental Authority, could give rise to a claim or proceeding which, if asserted or conducted with results unfavorable to the Company or any of the Subsidiaries, could reasonably be expected to have a Material Adverse Effect.

          (r) Financial Statements. The financial statements included in each of the SEC Filings present fairly, in all material respects, the consolidated financial position of the Company as of the dates shown and its consolidated results of operations and cash flows for the periods shown, and such financial statements have been prepared in conformity with United States generally accepted accounting principles (“GAAP”) applied on a consistent basis (except as may be disclosed therein or in the notes thereto).

          (s) Insurance Coverage. The Company and each Subsidiary maintain in full force and effect insurance coverage that is customary for comparably situated companies for the

-13-

business being conducted and properties owned or leased by the Company and each Subsidiary. No default or event has occurred that could give rise to a default under any such policy.

          (t) Brokers and Finders.

          (u) No Directed Selling Efforts or General Solicitation. Neither the Company nor any person acting on its behalf has conducted any general solicitation or general advertising (as those terms are used in Rules 501 through 508 of the Securities Act (“Regulation D”)) in connection with the offer or sale of the Securities.

          (v) No Integrated Offering. Neither the Company nor any of its Affiliates (as defined below), nor any person acting on its or their behalf has, directly or indirectly, made any offers or sales of any Company security or solicited any offers to buy any security, under circumstances that would adversely affect reliance by the Company on Section 4(2) of the Securities Act for the exemption from registration for the offer and sale of the Securities hereunder. For purposes of this Agreement, “Affiliate” shall have the meaning as defined in Rule 12b-2 of the Exchange Act.

          (w) Questionable Payments. Neither the Company nor any of its Subsidiaries nor, to the Company’s knowledge, any of their respective current or former shareholders, directors, officers, employees, agents or other persons acting on behalf of the Company or any Subsidiary, has on behalf of the Company or any Subsidiary or in connection with their respective businesses: (a) used any corporate funds for unlawful contributions, gifts, entertainment or other unlawful expenses relating to political activity; (b) made any direct or indirect unlawful payments to any governmental officials or employees from corporate funds; (c) established or maintained any unlawful or unrecorded fund of corporate monies or other assets; (d) made any false or fictitious entries on the books and records of the Company or any Subsidiary; or (e) made any unlawful bribe, rebate, payoff, influence payment, kickback or other unlawful payment of any nature.

          (x) Disclosures. The information relating to or concerning the Company, set forth in this Agreement or provided to the Holders in connection with the transactions contemplated by the Transaction Documents do not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements contained therein, in light of the circumstances under which they were made, not misleading. To the Company’s knowledge, there is no fact that has specific application to the Issuers (other than general economic or industry conditions) and that could reasonably be expected to have a Material Adverse Effect that has not been set forth in the SEC Filings, this Agreement or the Disclosure Schedules.

          (y) Transactions with Affiliates. Except as disclosed on Schedule 2(y) or the SEC Filings, none of the officers or directors of the Company and, to the Company’s knowledge, none of the employees of the Company is presently a party to any transaction with the Company or a

          (z) Acknowledgment Regarding Holders’ Purchase of the Securities. The Company acknowledges and agrees that no Holder is acting as a financial advisor or fiduciary of the Company (or in any similar capacity) with respect to this Agreement or the transactions contemplated hereby, the relationship between the Company and each Holder is “arms-length” and any statement made by any Holder or any of its representatives or agents in connection with this Agreement and the transactions contemplated hereby is merely incidental to such Holder’s purchase of the Securities and has not been relied upon by the Company, its officers or directors in any way. The Company further acknowledges that the Company’s decision to enter into this Agreement has been based solely on an independent evaluation by the Company and its representatives.

          (aa) Takeover Statutes. No “fair price,” “moratorium,” “control share acquisition” or other similar anti-takeover statute or regulation (including Section 203 of the Delaware General Corporation Law (the “DGCL”)) or any anti-takeover provision in the Certificate of Incorporation or By-Laws is applicable to the execution of the Transaction Documents or the other transactions contemplated hereby. Assuming the accuracy of the Holders’ representations and warranties contained in Section 3, the Board of Directors of the Company has taken all action so that the Holders will not be prohibited from entering into a “business combination” with the Company as an “interested stockholder” (in each case as such term is used in Section 203 of the DGCL) as a result of the execution of this Agreement or the consummation of the Transaction Documents or other transactions contemplated hereby.

          (bb) Fraudulent Transfer. Immediately following the Closing, neither the Company nor its Subsidiaries shall be insolvent (as such term is defined in the Uniform Fraudulent Transfer Act) and no transfer of property is being made by any of the Company or any of the Subsidiaries in connection with the transactions contemplated by this Agreement or the other Transaction Documents with the intent to hinder, delay, or defraud either present or future creditors of any of the Company or any of its Subsidiaries.

     3. Holders’ Representations. In connection with the Holders’ acquisition of the Units, each of the Holders, severally but not jointly, represents to the Company the following:

The Holder is a validly existing corporation, limited partnership or limited liability company and has all requisite corporate, partnership or limited liability company power and authority to enter into and perform its obligations under this Agreement and the other Transaction Documents, and invest in the Securities.

          (b) Authorization. The execution, delivery and performance by the Holder of the Transaction Documents have been duly authorized and the Transaction Documents each constitute the valid and legally binding obligation of the Holder, enforceable against the Holder in accordance

-15-

with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability, relating to or affecting creditors’ rights generally.

          (c) No Conflict. The execution, delivery and performance of the Transaction Documents by the Holder do not and will not conflict with or result in a breach or violation of any of the terms and provisions of, constitute a default (or an event that with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration of obligations, impairment of rights or cancellation under (i) the limited partnership or limited liability company agreement, as the case may be, of the Holder, each as in effect on the date hereof or as hereafter amended, or (ii)(a) any statute, rule, regulation or order of any Governmental Authority, or (b) any material agreement, or instrument to which the Holder is a party or by which the Holder is bound or to which any of their respective assets or properties is subject.

          (d) Purchase Entirely for Own Account. The Securities to be received by the Holder hereunder will be acquired for the Holder’s own account, not as nominee or agent, and not with a view to the resale or distribution of any part thereof in violation of the Securities Act, and the Holder has no present intention of selling, granting any participation in, or otherwise distributing the same in violation of the Securities Act. The Holder is not a registered broker dealer or entity engaged in the business of being a broker dealer. Notwithstanding anything in this Section 3(d) to the contrary, by making the representations herein, the Holder does not agree to hold the Securities 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 a registration statement or an exemption from the registration requirements under the Securities Act.

          (e) Investment Experience. The Holder acknowledges that it can bear the economic risk and complete loss of its investment in the Securities and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment contemplated hereby.

          (f) Disclosure of Information. The Holder has had an opportunity to receive all information related to the Company that it has requested and to ask questions of and receive answers from the Company regarding the Company, its business and the terms and conditions of the sale of the Securities to be received by the Holder hereunder. The Holder acknowledges review of copies of the SEC Filings. Neither such inquiries nor any other due diligence investigation conducted by the Holder shall modify, amend or affect the Holder’s right to rely on the Company’s representations and warranties contained in this Agreement, except as expressly set forth herein.

          (g) Restricted Securities. The Holder acknowledges and understands that the Units, including the underlying Notes and the Shares constitute, and that the Redemption Warrants, any other convertible securities issuable in accordance with the terms of the Notes and the Conversion Shares, if issued, will constitute, “restricted securities” under the Securities Act and must be held indefinitely unless a registration statement under the Securities Act is effective with respect to the transfer of such securities or an exemption from such registration is available.

-16-

          (h) Legends. It is understood that until (i) the Securities have been transferred pursuant to Rule 144 under the Securities Act (“Rule 144”), (ii) the Securities may be transferred pursuant to Rule 144(k) under the Securities Act, or (iii) a registration statement under the Securities Act is effective relating to the transfer of such Securities, certificates evidencing the Notes, Common Shares, and, if issued, the Redemption Warrants, any other convertible securities issuable in accordance with the terms of the Notes and the Conversion Shares, may bear the following or a substantially similar legend:

          “THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY APPLICABLE STATE SECURITIES LAW AND MAY NOT BE TRANSFERRED UNLESS (I) THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES LAW WITH RESPECT THERETO, (II) PURSUANT TO RULE 144 OF THE SECURITIES ACT OR (III) UPON THE ADVICE OF COUNSEL REASONABLY ACCEPTABLE TO THE ISSUER, REGISTRATION UNDER THE SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES LAW IS NOT REQUIRED IN CONNECTION WITH SUCH TRANSFER”

          The Company agrees that the legend set forth above shall be removed and the Company shall issue a certificate without such legend to the holder of any Securities upon which it is stamped if (a) such Security may be transferred pursuant to an effective registration statement under the Securities Act; (b) such holder provides the Company with reasonable assurances that such Security can be transferred pursuant to Rule 144; or (c) such holder provides the Company with an opinion of counsel, in form, substance and scope customary for opinions of counsel in comparable transactions, to the effect that a sale or transfer of such Security may be made without registration under the Securities Act. In the event the above legend is removed from any Security and thereafter the effectiveness of a registration statement covering such Security is suspended or the Company determines that a supplement or amendment thereto is required by applicable securities laws, then upon reasonable advance written notice to the Holders, the Company may require that the above legend be placed on any such Security that cannot then be sold pursuant to an effective registration statement or pursuant to Rule 144 and the Holders shall cooperate in the replacement of such legend. Such legend shall thereafter be removed when such Security may again be transferred pursuant to an effective registration statement or pursuant to Rule 144.

          (i) Accredited Investor. The Holder is, and was at the time the Securities were offered to the Holder, an accredited investor as defined in Rule 501(a) of the Securities Act.

          (j) Brokers and Finders. No person will have, as a result of the transactions contemplated by this Agreement, any valid right, interest or claim against or upon the Company, any

          (k) Taxes. The Holder understands that the Holder’s investment in the Company may result in tax consequences.

               (2) Any sales, transfer and other similar Taxes and any recording and filing fees that may be imposed by reason of the issuance, sale, transfer and/or delivery of any Securities by the Issuers to the Holders shall be borne and paid by the Issuers.

          (b) Form D; Blue Sky Laws. The Company shall file with the Securities and Exchange Commission a Form D with respect to the Securities as required under Regulation D and provide a copy thereof to the Holders promptly after such filing. The Company shall, on or before the time of Closing, take such action as the Company shall reasonably determine is necessary to qualify the Securities for sale to the Holders pursuant to this Agreement under applicable securities or “blue sky” laws of the states of the United States or obtain exemption therefrom, and shall provide evidence of any such action so taken to the Holders on or prior to the time of Closing. Within two (2) business days after the time of Closing, the Company shall file a Form 8-K concerning this Agreement and the transactions contemplated hereby, which filing shall contain all material information relating to the Company and the transactions entered into herewith.

          (c) Reporting Status. So long as any Holder beneficially owns any of the Securities, the Company shall (i) timely file all reports required to be filed with the Securities and Exchange Commission (the “SEC”) pursuant to the Exchange Act, (ii) take such further action as any Holder may reasonably request to make available adequate current public information with respect to the Company meeting the current public information requirements of Rule 144(c) under the Securities Act, to the extent required to enable such Holder to sell Securities held by the Holder without registration under the Securities Act within the limitation of the exemptions provided by (A) Rule 144 under the Securities Act, as such Rule may be amended from time to time, or (B) any similar rule or regulation hereafter adopted by the SEC. The Company shall not terminate its status as an issuer required to file reports under the Exchange Act even if the Exchange Act or the rules and regulations thereunder would permit such termination. In addition, the Company shall take all actions necessary to meet the “registrant eligibility” requirements set forth in the general instructions

The Company will use its best efforts to continue the listing and trading of its Common Stock on the OTC Electronic Bulletin Board (the “Bulletin Board”) or on the NASDAQ National Market (“NNM”), the Nasdaq SmallCap Market (the “SmallCap Market”) the New York Stock Exchange (“NYSE”) or the American Stock Exchange (“AMEX”) and will comply in all respects with the reporting, filing and other obligations under the bylaws or rules of the National Association of Securities Dealers, Inc. (the “NASD”), such exchanges, or such electronic system, as applicable.

          (j) Legal Compliance. The Company shall conduct its business and the business of the Subsidiaries in compliance with all laws, ordinances or regulations of governmental entities applicable to such businesses, except where the failure to do so would not have a Material Adverse Effect.

          (a) Appointment of Collateral Agent. MHR Capital Partners LP (“MHR”) is hereby appointed to act on behalf of all the Holders as collateral agent (the “Collateral Agent”) under this Agreement and the Notes. The provisions of this Section 7 are solely for the benefit of Collateral Agent and the Holders and no other person shall have any rights as a third party beneficiary of any of the provisions hereof. In performing its functions and duties under this Agreement and the Notes, Collateral Agent shall act solely as agent of the Holders and does not assume and shall not be deemed to have assumed any obligation toward or relationship of agency or trust with or for the Issuers or any other person. The Collateral Agent shall have no duties or

-20-

responsibilities except for those expressly set forth in this Agreement and the Notes. The duties of the Collateral Agent shall be mechanical and administrative in nature and the Collateral Agent shall not have, or be deemed to have, by reason of this Agreement, any other Transaction Document or otherwise a fiduciary relationship in respect of any Holder. Except as expressly set forth in this Agreement and the Notes, the Collateral Agent shall not have any duty to disclose, and shall not be liable for failure to disclose, any information relating to any of the Issuers or any of their respective Subsidiaries that is communicated to or obtained by MHR or any of its Affiliates in any capacity. Neither the Collateral Agent nor any of its Affiliates nor any of their respective officers, directors, employees, agents or representatives shall be liable to any Holder for any action taken or omitted to be taken by it hereunder or under any other Transaction Document, or in connection herewith or therewith, except for damages caused by its or their own gross negligence or willful misconduct.

     If the Collateral Agent shall request instructions from the Holders holding a majority of the outstanding principal amount of the Notes (the “Required Holders”) or all affected Holders with respect to any act or action (including failure to act) in connection with this Agreement or the Notes, then the Collateral Agent shall be entitled to refrain from such act or taking such action unless and until such Collateral Agent shall have received instructions from the Required Holders or all affected Holders, as the case may be, and the Collateral Agent shall not incur liability to any person by reason of so refraining. The Collateral Agent shall be fully justified in failing or refusing to take any action hereunder or under the Notes (a) if such action would, in the opinion of the Collateral Agent, be contrary to law or the terms of this Agreement or the Notes, (b) if such action would, in the opinion of such Agent, expose the Collateral Agent to any liabilities under any environmental laws, rules or ordinances or (c) if the Collateral Agent shall not first be indemnified to its satisfaction against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. Without limiting the foregoing, no Holder shall have any right of action whatsoever against the Collateral Agent as a result of the Collateral Agent acting or refraining from acting hereunder or under the Notes in accordance with the instructions of Required Holders or all affected Holders, as applicable.

          (b) Collateral Agent’s Reliance, Etc. Neither the Collateral Agent nor any of its Affiliates nor any of their respective directors, officers, agents or employees shall be liable to any Holder for any action taken or omitted to be taken by it or them under or in connection with this Agreement or the Notes, except for damages caused by its or their own gross negligence or willful misconduct. Without limiting the generality of the foregoing, the Collateral Agent: (a) may treat the payee of any Note as the holder thereof until the Collateral Agent receives written notice of the assignment or transfer thereof signed by such payee and in form reasonably satisfactory to the Collateral Agent; (b) may consult with legal counsel, independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the advice of such counsel, accountants or experts; (c) makes no warranty or representation to any Holder and shall not be responsible to any Holder for any statements, warranties or representations made in or in connection with this Agreement or the Notes; (d) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of this Agreement or the Notes on the part of any of the Issuers or to inspect the Collateral (including the books and records) of any of the Issuers; (e) shall not be responsible to

-21-

any Holder for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or the Notes or any other instrument or document furnished pursuant hereto or thereto; and (f) shall incur no liability under or in respect of this Agreement or the Notes by acting upon any notice, consent, certificate or other instrument or writing (which may be by telecopy, telegram, cable or telex) believed by it to be genuine and signed or sent by the proper party or parties.

     (c) MHR and Affiliates. With respect to its or its Affiliates ownership of Notes, MHR shall have the same rights and powers under this Agreement and the Notes as any other Holder and may exercise the same as though it were not the Collateral Agent; and the term “Holder” or “Holders” shall, unless otherwise expressly indicated, include MHR in its individual capacity. Similarly, the fact that MHR acts as Collateral Agent shall not in any way impair the rights and powers under this Agreement or the Notes of any Holders who are Affiliates of MHR. MHR and its Affiliates may lend money to, invest in, and generally engage in any kind of business with, any of the Issuers, any of their Affiliates and any person who may do business with or own securities of any of the Issuers or any such Affiliate, all as if MHR were not the Collateral Agent and without any duty to account therefor to Holders.

     (d) Indemnification. The Holders agree to indemnify the Collateral Agent (to the extent not reimbursed by the Issuers and without limiting the obligations of Issuers hereunder), ratably according to their respective pro rata ownership of the principal amount of outstanding Notes, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against the Collateral Agent in any way relating to or arising out of this Agreement or the Notes or any action taken or omitted to be taken by the Collateral Agent in connection therewith; provided, that no Holder shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Collateral Agent’s gross negligence or willful misconduct. Without limiting the foregoing, each Holder agrees to reimburse the Collateral Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including reasonable counsel fees) incurred by the Collateral Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement and the Notes, to the extent that the Collateral Agent is not reimbursed for such expenses by the Issuers.

     (e) Successor Agents. The Collateral Agent may resign at any time by giving not less than five (5) days’ prior written notice thereof to the Holders. By a vote of the Required Holders, the Holders may remove the Collateral Agent at any time by giving not less than thirty (30) days’ prior written notice thereof to the Collateral Agent. Upon any such resignation or removal, the Required Holders shall have the right to appoint a successor Collateral Agent. If no successor Collateral Agent shall have been so appointed by the Required Holders and shall have accepted such appointment within such thirty (30) days or five (5) after the date of notice of resignation or removal was given, as applicable, then the Collateral Agent may, on behalf of the Holders, appoint a successor Collateral Agent, which shall be a Holder, if a Holder is willing to accept such

-22-

appointment. If no successor Collateral Agent has been appointed pursuant to the foregoing, within thirty (30) days or five (5) after the date of notice of resignation or removal was given, as applicable, such resignation or removal shall become effective and the Required Holders shall thereafter perform all the duties of such Collateral Agent hereunder until such time, if any, as the Required Holders appoint a successor Collateral Agent as provided above. Any successor Collateral Agent appointed by Required Holders hereunder shall be subject to the approval of the Issuers, such approval not to be unreasonably withheld or delayed; provided, that such approval shall not be required if a Default or an Event of Default has occurred and is continuing. Upon the acceptance of any appointment as Collateral Agent, as applicable, hereunder by a successor Collateral Agent, such successor Collateral Agent shall succeed to and become vested with all the rights, powers, privileges and duties of the resigning Collateral Agent. Upon the earlier of the acceptance of any appointment as Collateral Agent, hereunder by a successor Collateral Agent or the effective date of such Collateral Agent’s resignation or removal, such Collateral Agent shall be discharged from its duties and obligations under this Agreement and the Notes, except that any indemnity rights or other rights in favor of such Collateral Agent shall continue. After any Collateral Agent’s resignation or removal hereunder, the provisions of this Section 7 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was acting as such Collateral Agent under this Agreement and the Notes.

The rights of the Indemnified Parties under this Section 9(j) shall be in addition to (a) any cause of action or similar right of any Indemnified Party against the Company or other persons, or (b) any liabilities the Company or any of its Subsidiaries may be subject to pursuant to any applicable law.

               (2) Each Indemnified Party entitled to indemnification hereunder will (a) give prompt written notice to the Indemnifying Party of any claim with respect to which it seeks indemnification or contribution pursuant to this Agreement and (b) permit such Indemnifying Party to assume the defense of such claim with counsel selected by the Indemnifying Party and reasonably satisfactory to the Indemnified Party; provided, however, that any Indemnified Party entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party unless (x) the Indemnifying Party has agreed in writing to pay such fees and expenses, (y) the Indemnifying Party shall have failed to assume the defense of such claim within 20 days of delivery of the written notice of the Indemnified Party with respect to such claim or failed to

-25-

employ counsel selected by such Indemnifying party and reasonably satisfactory to such Indemnified Party or (z) in the reasonable judgment of such Indemnified Party, based upon advice of its counsel, a conflict of interest may exist between such Indemnified Party and the Indemnifying Party with respect to such claims (in which case, if the Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the defense of such claim on behalf of such Indemnified Party); provided, further, that an Indemnifying Party who is not entitled to, or elects not to, assume the defense of a claim on behalf of all Indemnified Parties shall not be obligated to pay the fees and expenses of more than one counsel (in addition to local counsel) for all Indemnified Parties. If the Indemnifying Party assumes the defense of the claim, it shall not be subject to any liability for any settlement or compromise made by the Indemnified Party without its consent (but such consent shall not be unreasonably withheld). In connection with any settlement negotiated by an Indemnifying Party, no Indemnifying Party shall, and no Indemnified Party shall be required by an Indemnifying Party to, (i) enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to the Indemnified Party of a release from all liability in respect to such claim or litigation (ii) enter into any settlement that attributes by its terms liability to the Indemnified Party, or (iii) consent to the entry of any judgment that does not include as a term thereof a full dismissal of the litigation or proceeding with prejudice. In addition, without the consent of the Indemnified Party (which consent will not be unreasonably withheld), no Indemnifying Party will be permitted to consent to entry of any judgment or enter into any settlement which provides for any action on the part of the Indemnified Party other than the payment of money damages which are to be paid in full by the Indemnifying Party. If an Indemnifying Party fails or elects not to assume the defense of a claim pursuant to clause (y) above, or is not entitled to assume or continue the defense of such claim pursuant to clause (z) above, the Indemnified Party shall have the right without prejudice to its right of indemnification hereunder to, in its discretion exercised in good faith and upon advice of counsel, to contest, defend and litigate such claim and may settle such claim, either before or after the initiation of litigation, at such time and upon such terms as the Indemnified Party deems fair and reasonable, provided that at least 10 days prior to any settlement, written notice of its intention to settle is given to the Indemnifying Party. If requested by the Indemnifying Party, the Indemnified Party agrees (at no expense to the Indemnified Party) to cooperate with the Indemnifying Party and its counsel in contesting any claim that the Indemnifying Party elects to contest.
