ARTICLE VI
THE COLLATERAL AGENT

Section 6.01. No Implied Duty. The Collateral Agent shall not have any
duties or responsibilities except those expressly assumed by it in this
Agreement and the other Collateral Documents and shall not be required to take
any action which is contrary to applicable law or any provision of this
Agreement or the other Collateral Documents. Where the Collateral Agent is
permitted but not required to take any action pursuant to any Collateral
Document, the Collateral Agent may take any such action but shall have no
obligation to take any such action without the direction of the Directing
Noteholders and the Collateral Agent shall not be liable to any party for not
taking such action if the Directing Noteholders have not directed the Collateral
Agent to take such action. The Collateral Agent makes no representation as to
the existence, validity, value, genuineness, perfection, priority or the
collectibility of any security or other document or other instrument held by or
delivered to the Collateral Agent. The Collateral Agent shall not be called upon
to advise any party as to the wisdom in taking or refraining to take any action
with respect to the Collateral.

Section 6.02. Appointment of Co-Agents and Sub-Agents. The Collateral
Agent may employ agents and appoint sub-agents or co-collateral agents as it
determines appropriate in the performance of its duties hereunder. The
Collateral Agent will exercise reasonable care in selecting any such agent,
sub-agent or co-collateral agent but shall not otherwise be responsible or
liable for any act or omission of any such agent, sub-agent or co-collateral
agent.

Section 6.03. Other Agreements. The Collateral Agent has accepted and
is bound by the Collateral Documents delivered to it as of the date of this
Agreement and listed on Schedule 2.02 and, subject to Section 7.01(b) and this
Article VI, shall accept and be bound by all Collateral Documents delivered to
it at any time after the date of this Agreement. The Collateral Agent shall not
otherwise be bound by, or obligated to take cognizance of the provisions of, any
agreement to which it is not a party, including the Indenture. The Collateral
Agent shall not be responsible for compliance with the terms of any Note
Document by any Loan Party and shall have no duty to monitor any such
compliance.

Section 6.04. Solicitation of Instructions. The Collateral Agent may
at any time solicit confirmatory instructions, including from the Directing
Noteholders or an order of a court of competent jurisdiction, as to any action
which it may be requested or required to take, or which it may propose to take,
in the performance of any of its obligations under this Agreement.

Section 6.05. Limitation of Liability. The Collateral Agent shall not
be responsible or liable for any action taken or omitted to be taken by it
hereunder or under any Collateral Document, except for its own gross negligence
or willful misconduct.

Section 6.06. Documents in Satisfactory Form. The Collateral Agent
shall be entitled to require that all agreements, certificates, opinions,
instruments and other documents at any time submitted to it, including those
expressly provided for in this Agreement, be delivered to it in a form and upon
substantive provisions reasonably satisfactory to it.

Section 6.07. Entitled to Rely. The Collateral Agent may rely
conclusively upon any certificate, notice or other document (including any
electronic transmission) reasonably believed by it to be genuine and correct and
to have been signed or sent by or on behalf of the proper Person or Persons and
need not investigate any fact or matter stated in any such document. The
Collateral Agent may seek and rely upon any judicial order or judgment, upon any
advice, opinion or statement of legal counsel, independent consultants and other
experts selected by it in good faith and upon any certification, instruction,
notice or other writing delivered to it by any Loan Party in compliance with the
provisions of this Agreement or delivered to it by the Trustee as to the
Noteholders whose action or consent is required for an instruction of Directing
Noteholders, without being required to determine the authenticity thereof or the
correctness of any fact stated therein or the propriety or validity of service
thereof. The Collateral Agent may act in reliance upon any instrument comporting
with the provisions of this Agreement or any signature reasonably believed by it
to be genuine and may assume that any Person purporting to give notice or
receipt or advice or make any statement or execute any document in connection
with the provisions hereof has been duly authorized to do so. To the extent an
officers' certificate or an opinion of counsel is required or permitted under
this Agreement to be delivered to the Collateral Agent in respect of any matter,
the Collateral Agent may rely conclusively on such officers' certificate or
opinion of counsel as to such matter. The Collateral Agent may request an
opinion of counsel, a certificate of a Responsible Officer, or both, at any time
when it is required or requested to take any action (other than pursuant to
Sections 2.04, 3,02, 5.01, and 6.03 hereof or any similar provision of any
Collateral Document) hereunder or under any Collateral Document stating that
such action is permitted or authorized pursuant to the terms hereof and of the
Note Documents and that all conditions precedent to the taking of such action
have been complied with and the Collateral Agent may rely conclusively on such
officer's certificate or opinion of counsel with respect thereto.

Section 6.08. Events of Default. The Collateral Agent shall not be
required to inquire as to the occurrence or absence of any Event of Default
under the Indenture or any other Note Document and shall not be affected by or
required to act upon any notice or knowledge as to the occurrence of any Event
of Default unless and until it receives a notice pursuant to Section 4.02.

Section 6.09. Actions by Collateral Agent. As to any matter not
expressly provided for by this Agreement, the Collateral Agent shall act or
refrain from acting as directed by the Directing Noteholders and shall be fully
protected in doing so.

Section 6.10. Security or Indemnity in Favor of the Collateral Agent.
The Collateral Agent shall not be required to advance or expend any funds or
otherwise incur any financial liability in the performance of its duties or the
exercise of its powers or rights hereunder unless it has been provided with
security or indemnity which it, in its discretion, deems sufficient against any
and all liability or expense which may be incurred by it by reason of taking or
continuing to take such action. The Loan Parties hereby jointly and severally
agree to provide

such security or indemnity to the Collateral Agent promptly upon request by the
Collateral Agent therefor.

Section 6.11. Resignation or Removal of the Collateral Agent. Subject
to the appointment of a successor Collateral Agent as provided in Section 6.12
and the acceptance of such appointment by the successor Collateral Agent, (i)
the Collateral Agent may resign at any time by giving not less than 45 days'
notice of resignation to the Trustee and InSight, and (ii) the Collateral Agent
may be removed at any time, with or without cause, pursuant to the instructions
of the Directing Noteholders.

Section 6.12. Appointment of Successor Collateral Agent. Upon any such
resignation or removal, a successor Collateral Agent may be appointed by the
Trustee or by the instructions of the Directing Noteholders with the consent of
InSight. If no successor Collateral Agent shall have been so appointed and shall
have accepted such appointment within 45 days after the predecessor Collateral
Agent gave notice of resignation or was removed, the retiring Collateral Agent
may appoint a successor Collateral Agent, or petition a court of competent
jurisdiction for appointment of a successor Collateral Agent, which shall be a
bank or trust company (i) authorized to exercise corporate trust powers, (ii)

and obligations hereunder, and

(ii) the predecessor Collateral Agent, upon payment of all amounts
owed to it, shall promptly transfer all Collateral within its possession or
control to the possession or control of the successor Collateral Agent and
shall execute and deliver such notices, instructions and assignments as may
be necessary or desirable or reasonably requested by the successor
Collateral Agent to transfer to the successor Collateral Agent all Liens,
interests, rights, powers and remedies of the predecessor Collateral Agent
in respect of the Collateral or under the Collateral Documents. Thereafter
the predecessor Collateral Agent shall remain entitled to enforce the

of all present and future holders of Note Obligations, duly created, enforceable
and perfected first priority Liens (subject only to Permitted Liens (as defined

perfect, protect, assure or enforce the Liens and benefits intended to be

substitution, to execute, acknowledge and deliver such security documents,
instruments, certificates, notices and other documents and, subject to the
provisions of the Collateral Documents, take such other actions in the name,
