the Secured Parties. Each of  the Secured Parties agrees that any Secured Parties acting

	3. 	 	 Representations
and Warranties.    The Debtor hereby represents and warrants to the Secured Party
that:







                
(a)    Ownership of Collateral.    The Debtor is the legal and beneficial
owner of the Collateral (or, in the case of after-acquired Collateral, at the
time the Debtor acquires rights in the Collateral, will be the legal and
beneficial owner thereof). Except for the Security Interest granted to the
Secured Party pursuant to this Agreement, the Debtor has rights in or the power
to transfer the Collateral free and clear of any adverse Lien, security interest
or encumbrance except as created by this Security Interest, except for Permitted
Liens. Except for the financing statements listed in
Schedule 3, no financing statements covering any Collateral
or any proceeds thereof are on file in any public office (other than filings
listing the Secured Party as the secured party).



                
(b)    Valid Security Interest.    The Security Interest granted pursuant to
this Agreement will constitute a valid and continuing first priority, perfected
security interest in favor of the Secured Party in the Collateral for which
perfection is governed by the UCC or filing with the United States Copyright
Office or United States Patent and Trademark Office. Such Security Interest will
be prior to all other Liens on the Collateral, except for Permitted Liens.



                
(c)    Organization and Good Standing.    The Debtor has been duly
incorporated, and is validly existing and in good standing, under the laws of
the State of Delaware.

Debtor’s state of organization is Delaware and the Debtor’s exact
legal name as it appears in the official filings in the State of Delaware is as
set forth in the first paragraph of this Agreement. The Debtor has only one
jurisdiction of organization.



                
(e)    Location of Equipment and Inventory.    All Equipment and Inventory
are (i) located at the locations indicated on Schedule 4
(ii) in transit to such locations or (iii) in transit to a third party
purchaser which will become obligated on a Receivable to the Debtor upon
receipt. Except for Equipment and Inventory referred to in clauses (ii) and
(iii) of the preceding sentence, the Debtor has exclusive possession and control
of the Inventory and Equipment.



                
(g)    Delivery of Items.    Schedule 5 lists all
Instruments (other than checks received in the ordinary course of business),
letter-of-credit rights, Electronic Chattel paper and Chattel Paper of the
Debtor as of the date hereof. The Debtor has delivered to the Secured Party,
together with all necessary stock powers, endorsements, assignments and other
necessary instruments of transfer, the originals of all Receivables consisting

securities owned directly by the Debtor.

(h)    Receivables.    Each Receivable is genuine and enforceable
against the party obligated to pay the same (an “Account
Debtor”) free from any right of rescission, defense, setoff or
discount.



                
(i)    Insurance.    Each insurance policy maintained by the Debtor is
validly existing and is in full force and effect. The Debtor is not in default
in any material respect under the provisions of any insurance policy, and there
are no facts which, with the giving of notice or passage of time (or both),
would result in such a default under any material provision of any such
insurance policy. Set forth in Schedule 6 is a complete and
accurate list of the insurance of the Debtor in effect on the date of this
Agreement covering fire, public liability, property damage and worker’s
compensation, showing as of such date, (i) the type of insurance carried,
(ii) the name of the insurance carrier, and (iii) the amount of each
type of insurance carried.



                
(j)    This Agreement is effective to create a valid and continuing Lien upon the
Collateral. All action by the Debtor necessary to protect and perfect such Lien
on each item of the Collateral has been duly taken.



	4. 	 	 Covenants.    The
Debtor covenants and agrees with the Secured Party  that, from and after the date of this
Agreement until the Obligations are paid  in full:







                
(a)    Other Liens.    Except for the Security Interest and Permitted Liens,
the Debtor has rights in or the power to transfer the Collateral and its title
and will be able to do so hereafter free from any adverse Lien, security
interest or encumbrance, and the Debtor will defend the Collateral against the
claims and demands of all persons at any time claiming the same or any interest
therein.



                
(b)    Further Documentation.    At any time and from time to time, upon the
written request of the Secured Party, and at the sole expense of the Debtor, the
Debtor will promptly and duly authenticate and deliver such further instruments
and documents and take such further action as the Secured Party may reasonably
request for the purpose of obtaining or preserving the full benefits of
this Agreement and of the rights and powers herein granted including, without
limitation, filing any financing or continuation statements under the UCC in
effect with respect to the Liens created hereby. The Debtor also hereby
authorizes the Secured Party to file any such financing, amendment or
continuation statement without the authentication of the Debtor to the extent
permitted by applicable law. A reproduction of this Agreement shall be
sufficient as a financing statement (or as an exhibit to a financing statement
on form UCC-1) for filing in any jurisdiction.



                
(c)    Indemnification.    The Debtor agrees to defend, indemnify and hold
harmless the Secured Party against any and all liabilities, costs and expenses

any delay in paying, any and all excise, sales or other taxes which may be

(f)    Compliance with Laws, etc.    The Debtor (i) will comply with
all laws, rules, regulations and orders of any governmental authority applicable
to any part of the Collateral or to the operation of the Debtor’s

rule or obligation or order of any governmental authority, or any policy of
insurance covering the Collateral; provided,

law, rule, regulation or order; in any reasonable manner which does not, in the
reasonable opinion of the Secured Party, adversely affect the Secured
Party’s rights or the priority of its Liens on the Collateral.



                
(g)    Payment of Obligations.    The Debtor will pay promptly when due all

pursuant to Section 9313(c) of the UCC.



                
(s)    Letters of Credit.    If the Debtor is or becomes the beneficiary of
a letter of credit, the Debtor shall promptly, and in any event within two
business days after becoming a beneficiary, notify the Secured Party thereof and
enter into a tri-party agreement with the Secured Party and the issuer or
confirmation bank with respect to such Letter of Credit Rights assigning such
Letter of Credit Rights to the Secured Party and directing all payments
thereunder to the Secured Party, all in form and substance satisfactory to the
Secured Party.





-11-














                
(t)    Electronic Chattel Paper.    The Debtor shall take all steps
reasonably necessary to grant the Secured Party control of all Electronic
Chattel Paper in accordance with the UCC and all “transferable
records” as defined in each of the Uniform Electronic Transactions Act and
the Electronic Signatures in Global and National Commerce Act.



                
(u)    Intellectual Property Matters.    The Debtor shall notify the
Secured Party immediately if it knows or has reason to know (i) that any
application or registration relating to any of its Intellectual Property that is
material to the operation of its business may become abandoned or dedicated, or
(ii) of any adverse determination or development (including the institution of,
or any such determination or development in, any proceeding in the United States
Patent and Trademark Office, the United States Copyright Office or any court)
regarding the Debtor’s ownership of any Intellectual Property that is
material to the operation of its business, its right to register the same, or to
keep and maintain the same.



                
(v)    Intellectual Property Applications.    In no event shall the Debtor,
either itself or through any agent, employee, licensee or designee, file an
application for the registration of any patent, trademark or copyright with the
United States Patent and Trademark Office, the United States Copyright Office or
any similar office or agency without giving the Secured Party prior written
notice thereof, and, upon request of the Secured Party, the Debtor shall execute
and deliver any and all security documents as the Secured Party may request to
evidence the Secured Party’s Lien on such Intellectual Property and the
general intangibles of the Debtor relating thereto or represented thereby. The
Debtor hereby authorizes the Secured Party to amend this Agreement (without any
further action or consent from the Debtor) to include any such patent, trademark
or copyright as Collateral hereunder.



                
(w)    Intellectual Property Abandonment.    The Debtor shall take all
actions reasonably necessary or requested by the Secured Party to maintain and
pursue each application, to obtain the relevant registration and to maintain the
registration of its Intellectual Property, including the filing of applications
for renewal, affidavits of use, affidavits of noncontestability and opposition
and interference and cancellation proceedings.



                
(x)    Protection of Intellectual Property.    In the event that any of the Debtor's
Intellectual Property is infringed upon, or misappropriated or diluted by a third party, the Debtor shall notify
the Secured Party promptly after the Debtor learns thereof.  The Debtor shall, unless the Secured Party shall
determine that such Intellectual Property is in no way material to the conduct of its business or operations,
promptly sue for, and seek recovery of any and all damages resulting from such infringement, misappropriation or
dilution, and shall take such other actions as the Secured Party shall deem necessary under the circumstances to
protect such Intellectual Property.



                
(y)    Chattel Paper.    The Debtor shall type, print or stamp conspicuously
on the face of all original copies of all Collateral consisting of Chattel Paper
and Documents not in the possession of the Secured Party having a value in
excess of $100,000 a legend satisfactory to the Secured Party indicating
that such Chattel Paper is subject to the security interest granted hereby.





-12-














                
(z)    Limitation on Filing of Financing Statements.    The Debtor
acknowledges that it is not authorized to file any financing statement or
amendment or termination statement with respect to any financing statement
without the prior written consent of the Secured Party and agrees that it will
not do so without the prior written consent of the Secured Party, subject to the
Debtor’s rights under Section 9509(d)(2) of the UCC.



	5. 	 	 Event
of Default; the Secured Party’s Appointment as  Attorney-in-Fact.







                
(a)    Event of Default.    For purposes of this Agreement, the occurrence
of any one of the following events (each, an “Event of
Default”) shall constitute a default hereunder and under the Notes or
any of the other Credit Documents:



                       
(i)      The Debtor's failure to pay or discharge the Obligations in full in accordance
with the terms of the Notes or any of the other Credit Documents;


                       
(ii)     A breach of any representation or warranty made by the Debtor under this
Agreement, the Notes or any of the other Credit Documents as of the date thereof or any
other document or instrument entered into between the Debtor and the Secured
Party in connection herewith.


                       
(iii)    The Debtor's failure to observe or perform any other covenant, obligation,
condition or agreement contained in this Agreement, the Notes or any of the other Credit
Documents and such failure shall continue for 10 days after the earlier of (i)
the Debtor’s written acknowledgement of such failure and (ii) written
notice by the Secured Party to the Debtor of such failure.


                       
(iv)    The insolvency of the Debtor, the commission of any act of bankruptcy by the
Debtor, the execution by the Debtor of a general assignment for the benefit of
creditors, the filing by or against the Debtor of a petition in bankruptcy or
any petition for relief under the federal bankruptcy act or the continuation of
such petition without dismissal for a period of 90 days or more, or the
appointment of a receiver or trustee to take possession of the property or
assets of the Debtor.



                       
(v)     A default shall occur under the Notes or any of the other Credit Documents, or
any other agreement entered into between the Debtor and the Secured Party in
connection herewith.



                
(b)    Powers.    The Debtor hereby appoints the Secured Party and any
officer or agent of the Secured Party, with full power of substitution, as its
attorney-in-fact with full irrevocable power and authority in the place of the
Debtor and in the name of the Debtor or its own name, from time to time in the
Secured Party’s discretion so long as an Event of Default has occurred and
is continuing, for the purpose of carrying out the terms of this Agreement, to
take any appropriate action and to authenticate any instrument which may be
necessary or desirable to accomplish the purposes of this Agreement. Without
limiting the foregoing, so long as an Event of Default has occurred and is
continuing, the Secured Party shall have the right, without notice to, or the
consent of, the Debtor, to do any of the following on the Debtor’s behalf:





-13-














                       
(i)      to pay or discharge any taxes or Liens levied or placed on or threatened
against the Collateral;



                       
(ii)     to direct any party liable for any payment under any of the Collateral to make
payment of any and all amounts due or to become due thereunder directly to the Secured Party or as the Secured
Party directs;



                       
(iii)     to ask for or demand, collect, and receive payment of and receipt for, any
payments due or to become due at any time in respect of or arising out of any Collateral;



                       
(iv)     to commence and prosecute any suits, actions or proceedings at law or in
equity in any court of competent jurisdiction to enforce any right in respect of any Collateral;



                       
(v)      to defend any suit, action or proceeding brought against the Debtor with
respect to any Collateral;



                       
(vi)     to settle, compromise or adjust any suit, action or proceeding described in
subsection (v) above and to give such discharges or releases in connection therewith as the Secured Party may
deem appropriate;



                       
(vii)     to assign any patent right included in the Collateral of the Debtor (along
with the goodwill of the business to which any such patent right pertains),
throughout the world for such term or terms, on such conditions, and in such
manner, as the Secured Party shall in its sole discretion determine; and



                       
(viii)    generally, to sell, transfer, pledge and make any agreement with respect to or
otherwise deal with any of the Collateral and to take, at the Secured Party’s option
and the Debtor’s expense, any actions which the Secured Party deems
necessary to protect, preserve or realize upon the Collateral and the Secured
Party’s Liens on the Collateral and to carry out the intent of this
Agreement, in each case to the same extent as if the Secured Party were the
absolute owner of the Collateral for all purposes.



                The
Debtor hereby ratifies whatever actions the Secured Party shall lawfully do or
cause to be done in accordance with this Section 5. This power of attorney shall
be a power coupled with an interest and shall be irrevocable.



                
(c)    No Duty on the Secured Party’s Part.    The powers conferred on
the Secured Party by this Section 5 are solely to protect the Secured
Party’s interests in the Collateral and shall not impose any duty upon it
to exercise any such powers. The Secured Party shall be accountable only for
amounts that it actually receives as a result of the exercise of such powers,
and neither the Secured Party nor any of its officers, directors, employees or
agents shall, in the absence of willful misconduct or gross negligence, be
responsible to the Debtor for any act or failure to act pursuant to this Section
5.



     6.           
Performance by the Secured Party of the Debtor’s Obligations.    
If the Debtor fails to perform or comply with any of its agreements or covenants
contained in this Agreement and the Secured Party performs or complies, or
otherwise causes performance or compliance,




-14-













with such
agreement or covenant in  accordance with the terms of this Agreement, then the expenses
of the Secured  Party incurred in connection with such performance or compliance shall be
payable by the Debtor to the Secured Party on demand and shall constitute
Obligations secured by this Agreement. 



     7.           
Remedies.    If an Event of Default has occurred and is continuing,
the Secured Party may exercise, in addition to all other rights and remedies
granted to it in this Agreement and in any other instrument or agreement
relating to the Obligations, all rights and remedies of a secured party under
the UCC. Without limiting the foregoing, the Secured Party, without demand of
performance or other demand, presentment, protest, advertisement or notice of
any kind (except any notice required by law) to or upon the Debtor or any other
person (all of which demands, defenses, advertisements and notices are hereby
waived), may in such circumstances collect, receive, appropriate and realize
upon any or all of the Collateral, and/or may sell, lease, assign, give an
option or options to purchase, or otherwise dispose of and deliver any or all of
the Collateral (or contract to do any of the foregoing), in one or more parcels
at a public or private sale or sales, at any exchange, broker’s board or
office of the Secured Party or elsewhere upon such terms and conditions as the
Secured Party may deem advisable, for cash or on credit or for future delivery
without assumption of any credit risk. The Secured Party shall have the right
upon any such public sale or sales and, to the extent permitted by law, upon any
such private sale or sales, to purchase all or any part of the Collateral so
sold, free of any right or equity of redemption in the Debtor, which right or
equity is hereby waived or released. The Secured Party shall apply the net
proceeds of any such collection, recovery, receipt, appropriation, realization
or sale, after deducting all reasonable expenses incurred therein or in
connection with the care or safekeeping of any of the Collateral or in any way
relating to the Collateral or the rights of the Secured Party under this
Agreement (including, without limitation, reasonable attorneys’ fees and
expenses) to the payment in whole or in part of the Obligations, in such order
as the Secured Party may elect, and only after such application and after the
payment by the Secured Party of any other amount required by any provision of
law, need the Secured Party account for the surplus, if any, to the Debtor. To
the extent permitted by applicable law, the Debtor waives all claims, damages
and demands it may acquire against the Secured Party arising out of the exercise
by the Secured Party of any of its rights hereunder. If any notice of a proposed
sale or other disposition of Collateral shall be required by law, such notice
shall be deemed reasonable and proper if given at least ten days before such
sale or other disposition. The Debtor shall remain liable for any deficiency if
the proceeds of any sale or other disposition of the Collateral are insufficient
to pay the Obligations and the fees and disbursements of any attorneys employed
by the Secured Party to collect such deficiency.



     8.           
Limitation on Duties Regarding Preservation of Collateral.    The
Secured Party’s sole duty with respect to the custody, safekeeping and
preservation of the Collateral, under Section 9207 of the UCC or otherwise,
shall be to deal with it in the same manner as the Secured Party deals with
similar property for its own account. Neither the Secured Party nor any of its
directors, officers, employees or agents shall be liable for failure to demand,
collect or realize upon all or any part of the Collateral or for any delay in
doing so or shall be under any obligation to sell or otherwise dispose of any
Collateral upon the request of the Debtor or otherwise.





-15-













     9.           
Powers Coupled with an Interest.    All authorizations and agencies
contained in this Agreement with respect to the Collateral are irrevocable and
are powers coupled with an interest.



     10.         
No Waiver; Cumulative Remedies.    The Secured Party shall not by any
act (except by a written instrument pursuant to Section 12(a) hereof),
delay, indulgence, omission or otherwise be deemed to have waived any right or
remedy hereunder or to have acquiesced in any default under the Notes or any of
the other Credit Documents or in any breach of any of the terms and conditions
of this Agreement. No failure to exercise, nor any delay in exercising, on the
part of the Secured Party, any right, power or privilege hereunder shall operate
as a waiver thereof. No single or partial exercise of any right, power or
privilege hereunder shall preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. A waiver by the Secured Party
of any right or remedy under this Agreement on any one occasion shall not be
construed as a bar to any right or remedy which the Secured Party would
otherwise have on any subsequent occasion. The rights and remedies provided in
this Agreement are cumulative, may be exercised singly or concurrently and are
not exclusive of any rights or remedies provided by law.



     11.         
Termination of Security Interest.    Upon satisfaction of the
Debtor’s obligations pursuant to the Notes, the security interest granted
herein shall terminate and all rights to the Collateral shall revert to the
Debtor. Upon any such termination, the Secured Party shall authenticate and
deliver to the Debtor such documents as the Debtor may reasonably request to
evidence such termination.



     12.         Miscellaneous.



                 
(a)    Amendments and Waivers.    Any term of this Agreement may be amended with the written
consent of the Debtor and of Secured Parties holding a majority in interest of
the principal amount of Notes outstanding. Notwithstanding the foregoing or any
other provision of this Agreement, no amendment or waiver that adversely affects
a Secured Party in a manner different from all of the Secured Parties may be
effected without the written consent of such Secured Party. Any amendment or
waiver effected in accordance with this Section 12(a) shall be binding upon
the parties and their respective successors and assigns.



                 
(b)    Transfer; Successors and Assigns.    The terms and
conditions of this Agreement shall be binding upon the Debtor and its successors
and assigns, as well as all persons who become bound as a debtor to this
Agreement and inure to the benefit of the Secured Party and its successors and
assigns. Nothing in this Agreement, express or implied, is intended to confer
upon any party other than the parties hereto or their respective successors and
assigns any rights, remedies, obligations or liabilities under or by reason
of this Agreement, except as expressly provided in this Agreement.



                 
(c)    Governing Law.    This Agreement and all acts and transactions
pursuant hereto and the rights and obligations of the parties hereto shall be
governed, construed and interpreted in accordance with the laws of the State of
California, without giving effect to principles of conflicts of law.





-16-













                 
(d)    Counterparts.    This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original and all of which
together shall constitute one instrument.



                 
(e)    Titles and Subtitles.    The titles and subtitles used in this
Agreement are used for convenience only and are not to be considered in
construing or interpreting this Agreement.



                 
(f)    Notices.    Any notice required or permitted by this Agreement shall
be in writing and shall be deemed sufficient upon receipt, when delivered
personally or by courier, overnight delivery service or confirmed facsimile, or
48 hours after being deposited in the U.S. mail as certified or registered mail
with postage prepaid, if such notice is addressed to the party to be notified at
such party’s address or facsimile number as set forth below or as
subsequently modified by written notice.



                 
(h)    Payments Free of Taxes, Etc.    All payments made by the
Debtor under this Agreement shall be made by the Debtor free and clear of and
without deduction for any and all present and future taxes, levies, charges,
deductions and withholdings. In addition, the Debtor shall pay upon demand any
stamp or other taxes, levies or charges of any jurisdiction with respect to the
execution, delivery, registration, performance and enforcement of this
Agreement. Upon request by the Secured Party, the Debtor shall furnish evidence
satisfactory to the Secured Party that all requisite authorizations and
approvals by, and notices to and filings with, governmental authorities and
regulatory bodies have been obtained and made and that all requisite taxes,
levies and charges have been paid.



                 
(i)    Severability.    If one or more provisions of this Agreement are held
to be unenforceable under applicable law, the parties agree to renegotiate such
provision in good faith, in order to maintain the economic position enjoyed by
each party as close as possible to that under the provision rendered
unenforceable. In the event that the parties cannot reach a mutually agreeable
and enforceable replacement for such provision, then (i) such provision
shall be excluded from this Agreement, (ii) the balance of the Agreement
shall be interpreted as if such provision were so excluded and (iii) the
balance of the Agreement shall be enforceable in accordance with its terms.



                 
(j)    Entire Agreement.    This Agreement, and the documents referred to
herein constitute the entire agreement between the parties hereto pertaining to
the subject matter hereof, and any and all other written or oral agreements
existing between the parties hereto concerning such subject matter are expressly
canceled.



                 
(k)    Amendment and Restatement.    Effective upon execution of this
Agreement by Debtor, Optel LLC, and Optel Capital, the Fifth Amended and
Restated Security Agreement by and among Debtor, Optel LLC, and Optel Capital
dated as of December 10, 2003, is hereby amended and restated in its entirety to
read as set forth in this Agreement.
