         (d)62.2 Collateral Agent shall not be required to exercise any

applicable Investor Document following receipt by Collateral Agent from any
Secured Party of a Notice of Default (as hereinafter defined) and may (or shall
within thirty (30) days (or such shorter period as is acceptable to the
Collateral Agent), following receipt of written notice from a Secured Party
directing Collateral Agent to exercise commercially reasonable remedies under
the applicable Investor Documents and applicable law, commence exercising its
right and remedies under the applicable Investor Documents or otherwise

the "Required Secured Parties") with respect to any such action. For purposes
hereof, the term "Notice of Default" means a notice delivered by a Secured Party
to Collateral Agent stating that an Event of Default under and as defined in any
Investor Document has occurred and is continuing beyond any applicable cure or
grace period. Notwithstanding the provisions of this Section 2 (d) and anything
else to the contrary in the Investor Documents (but subject to the immediately
following proviso), in the event that prior to the March 31, 2006, there shall
occur and be continuing an Event of Default pursuant to any Laurus Preference
Obligation or any 2004 Laurus Document which shall, as a result thereof, result
in an Event of Default under, and as defined in, the Laurus Defined Obligations
or the 2005 Laurus Documents (a "Cross Default") and Laurus shall deliver a
Notice of Default in respect of the Laurus Defined Obligations as a result of a
Cross Default (a "Cross Default Notice of Default"), the Collateral Agent shall
not have any right, power or authority, without first being in receipt of the
approval of each of the Required Sands Creditors and the Required Laurus
Creditors, to accelerate, liquidate, sell or otherwise act in respect of the
Shared Collateral (each, a "Remedial Action") for the purpose of obtaining the
payment of the Laurus Obligations (it being understood that nothing contained in
this sentence shall affect in any respect any right of Collateral Agent to take
any Remedial Action following the provision of a Notice of Default by Laurus as
a result of the occurrence of any Event of Default (other than a Cross Default)
under, or in respect of, any 2005 Laurus Document); provided that,
notwithstanding anything to the contrary contained in this sentence, (I) in the
event that a Cross Default Notice of Default is delivered on or after September
30, 2005 and prior to December 31, 2005, Laurus may take Remedial Actions to
collect up to 15% of any amounts received for the benefit of the Collateral
Agent on or after September 30, 2005 and prior to December 31, 2005 by the
Lockbox Bank (as defined in the 2005 Laurus Master Security Agreement) in any
Lockbox (as defined in the 2005 Laurus Master Security Agreement) and (II) in
the event that a Cross Default Notice of Default is delivered on or after
December 31, 2005 and prior to March 31, 2006, Laurus may take Remedial Actions
to collect up to 30% of any amounts received for the benefit of the Collateral
Agent on or after December 31, 2005 and prior to March 31, 2006 by the Lockbox
Bank in any Lockbox (as defined in the 2005 Laurus Master Security Agreement).
Any such collections pursuant to the immediately preceding proviso shall be
solely applied by the Collateral Agent to the reduction of the Laurus Preference
Obligations and shall not, cumulatively, exceed an amount equal to the Laurus
Collateral Preference Amount.

Subsidiary or any other Person. Collateral Agent shall have no duties or
responsibilities except for those expressly set forth in this Agreement. The

for failure to disclose, any information relating to Issuer or any Subsidiary
that is communicated to or obtained by Collateral Agent or any of its affiliates
in any capacity.

         (f)62.4 If Collateral Agent shall request instructions from any Secured
Party with respect to any act or action (including failure to act) in connection
with this Agreement or any other Investor Document, Collateral Agent shall be
entitled to refrain from such act or taking such action unless and until
Collateral Agent shall have received instructions from such Secured Party and
Collateral Agent shall not incur liability to any Person by reason of so
refraining. Collateral Agent shall be fully justified in failing or refusing to
take any action hereunder or under any other Investor Document (i) if such
action would, in the opinion of Collateral Agent, be contrary to law or the
terms of this Agreement or any other Investor Document or (ii) if 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 Secured
Party shall have any right of action whatsoever against Collateral Agent as a
result of Collateral Agent's acting or refraining from acting hereunder or under
any other Investor Document in accordance with the instructions of the Secured
Parties.

         (g)62.5 Anything in this Agreement or any other Investor Document to
the contrary notwithstanding, each Secured Party hereby agrees with each other
Secured Party that no Secured Party shall take any action to protect or enforce
its rights arising out of the Investor Documents (including exercising any
rights of setoff) without first obtaining the prior written consent of
Collateral Agent and the Required Secured Parties, it being the intent of the
Secured Parties that any such action to protect or enforce rights under the
Investor Documents shall be taken in concert and at the direction or with the
consent of Collateral Agent or Required Secured Parties, as applicable.

         (h)62.6 The powers conferred on the Collateral Agent hereunder are
solely to protect the interest of the Secured Parties (including, without
limitation, the Collateral Agent in its individual Secured Party capacity) in
the Shared Collateral and, except as expressly set forth in the preceding clause
(d), shall not impose any duty upon the Collateral Agent to exercise any such
powers. Except for the safe custody of any Shared Collateral in its possession
and the accounting for moneys actually received by it hereunder, the Collateral
Agent shall have no duty as to any Shared Collateral, whether or not the
Collateral Agent or any Secured Party has or is deemed to have knowledge of such
matters, or as to the taking of any necessary steps to preserve the rights
against any parties or any other rights pertaining to any Shared Collateral.

         (i)62.7 The Issuer and each Subsidiary hereby consent and agree, upon
request by the Collateral Agent, to execute and deliver such agreements,
instruments and documents as the Collateral Agent may deem desirable to create,
preserve and/or release the liens and security interests in the Shared
Collateral, including any release in connection with any sale, transfer or other
disposition of the Shared Collateral or any part thereof in accordance with any
Investor Document), or for application thereof pursuant to the terms of the
Investor Documents.

         SECTION 3.63. Collateral Agent's Reliance. Etc. Neither the Collateral
Agent nor any of its directors, officers, partners, managers, members, agents or
employees shall be liable for any action taken or omitted to be taken by it or

decision). Without limiting the generality of the foregoing, the Collateral

Investor Document by acting upon any notice, consent, certificate or other

party or parties.

         SECTION 4.64. The Collateral Agent in Its Individual Capacity. With
respect to the Obligations owing to it under the Investor Documents, the
Collateral Agent in its individual capacity as a Secured Party shall have the
same rights and powers, and have the same obligations, under the Investor
Documents as any other Secured Party and may exercise the same as though it were
not the Collateral Agent; and the term Secured Party shall, unless otherwise
expressly indicated, include Laurus or such other Person, or any other Person
serving as the Collateral Agent in its individual capacity. Laurus, or any other
Person serving as the Collateral Agent, and its affiliates may accept deposits
from, lend money to, act as trustee under indentures of, accept other business
engagements from and generally engage in any kind of business with any Loan
Party, any of its subsidiaries and any Person who may do business with or own

other Person were not the Collateral Agent and without any duty to account to
any Loan Party.

may resign at any time as Collateral Agent under this Agreement by giving
written notice thereof to the Secured Parties. Following any such resignation,

such resignation. Upon any such resignation under this Agreement, the Secured
Parties shall have the right to appoint a successor Collateral Agent under this
Agreement. If no successor Collateral Agent shall have been so appointed by the
Secured Parties, and shall have accepted such appointment, within 30 days after

rights, powers, discretion, privileges and duties of the retiring Collateral
Agent and the retiring Collateral Agent shall be discharged from its duties and
obligations under this Agreement without any other or further act or deed on the
part of such former Collateral Agent. After any retiring Collateral Agent's
resignation hereunder as Collateral Agent, the provisions of this Agreement

realization upon, any of the Shared Collateral, (iii) the exercise or
enforcement of any of the rights of the Collateral Agent or any Secured Party
hereunder or under any other Investor Document, or (iv) the failure by the
Issuer or any of its Subsidiaries to perform or observe any of the provisions
hereof. The Issuer and its Subsidiaries hereby acknowledge that all such

ACTIONS MAY BE BROUGHT BY THE SECURED PARTIES IN ANY STATE OR FEDERAL COURT OF
COMPETENT JURISDICTION AND THE ISSUER (ON ITS BEHALF AND ON BEHALF OF ITS
SUBSIDIARIES) IRREVOCABLY SUBMITS TO THE JURISDICTION OF SUCH STATE AND FEDERAL
COURTS AND IRREVOCABLY WAIVES ANY CLAIM OR DEFENSE OF INCONVENIENT FORUM OR LACK
OF PERSONAL JURISDICTION IN SUCH FORUM OR RIGHT OF REMOVAL OR RIGHT TO JURY
TRIAL UNDER ANY APPLICABLE LAW OR DECISION OR OTHERWISE. SERVICE OF ANY NOTICE,
