each of the Accounts and Contracts to observe and perform all the conditions and
obligations to be observed and performed by it thereunder, all in accordance
with the terms of any agreement giving rise to each such Account and in
accordance with and pursuant to the terms and provisions of each such Contract.
The Collateral Agent shall not have any obligation or liability under any
Account (or any agreement giving rise thereto) or under any Contract by reason
of or arising out of this Amended and Restated Security Agreement or the receipt
by the Collateral Agent of any payment relating to such Account or Contract
pursuant hereto, nor shall the Collateral Agent be obligated in any manner to

(or any agreement giving rise thereto) or under or pursuant to any Contract, to
make any payment, to make any inquiry as to the nature or the sufficiency of any
payment received by it or as to the sufficiency of any performance by any party
under any Account (or any agreement giving rise thereto) or under any Contract,

Agent and that payments in respect thereof shall be made directly to the

others communicate with account debtors on the Accounts and parties to the
Contracts to verify with them to its satisfaction the existence, amount and
terms of any Accounts or Contracts.

request and at the expense of the Grantor, the Grantor shall cause independent
public accountants or others satisfactory to the Collateral Agent to furnish to

after the occurrence and during the continuance of an Event of Default, any

received, duly indorsed by the Grantor to the Collateral Agent if required, in a
special collateral account maintained by the Collateral Agent, and, until so
turned over, shall be held by the Grantor in trust for the Collateral Agent,
segregated from other funds of the Grantor. Each deposit of any such Proceeds

hereinafter provided. At any time after the occurrence and during the
continuance of an Event of Default, at the Collateral Agent's election, the
Collateral Agent shall apply all or any part of the funds on deposit in said
special collateral account on account of the Obligations in such order as the
Collateral Agent may elect, and any part of such funds which the Collateral
Agent elects not so to apply and deems not required as collateral security for
the Obligations shall be paid over from time to time by the Collateral Agent to
the Grantor or to whomsoever may be lawfully entitled to receive the same. After
the occurrence and during the continuance of an Event of Default, at the
Collateral Agent's request, the Grantor shall deliver to the Collateral Agent

transactions which gave rise to the Accounts, including, without limitation, all

<PAGE>   8
      others except as permitted by the Amended and Restated Note Agreement. No
      security agreement, financing statement or other public notice with

      on all Collateral, which are, except as permitted by the Amended and

      all account debtors in respect of the Accounts will at such time be the
      correct amount actually owing by such account debtor or debtors
      thereunder. No amount payable to the Grantor under or in connection with
      any Account is evidenced by any Instrument or Chattel Paper which has not
      been delivered to the Collateral Agent. The place where the Grantor keeps
      its records concerning the Accounts is set forth on Schedule IV hereto.

            (d) Consents. No consent of any party (other than the Grantor) to

      documents and take such further action as the Collateral Agent may

      and powers herein granted, including, without limitation, the filing of
      any financing or continuation statements under the Uniform Commercial Code
      in effect in any such jurisdiction with respect to the Liens created

      jurisdiction. If any amount payable under or in connection with any of the
      Collateral shall be or become evidenced by any Instrument or Chattel
      Paper, such Instrument or Chattel Paper shall be immediately delivered to
      the Collateral Agent, duly endorsed in a manner satisfactory to the
      Collateral Agent, to be held as Collateral pursuant to this Amended and
      Restated Security Agreement.

            (b) Indemnification. The Grantor agrees to pay, and to save the

            (g) Limitations on Discounts, Compromises, Extensions of Accounts.
      Other than in the ordinary course of business as generally conducted by
      the Grantor over a period of time, the Grantor will not grant any
      extension of the time of payment of any of the Accounts, compromise,
      compound or settle the same for less than the full amount thereof,
      release, wholly or partially, any Person liable for the payment thereof,
      or allow any credit or discount whatsoever thereon, to the extent that the
      same, individually or in the aggregate, could have a material adverse
      effect on the business, properties, assets, liabilities, results of
      operations, condition (financial or other) or prospects of the Grantor.

            (h) Further Identification of Collateral. The Grantor will furnish
      to the Collateral Agent from time to time, statements and schedules
      further identifying and describing the Collateral and such other reports
      in connection with the Collateral as the Collateral Agent may reasonably
      request, all in reasonable detail.

            (i) Notices. The Grantor will advise the Collateral Agent promptly,
      in reasonable detail, (i) of any Lien (other than Liens created hereby or
      permitted under the Amended and Restated Note Agreement) on, or claim
      asserted against, any of the Collateral, (ii) of the opening by the
      Grantor of any bank or deposit account after the Closing Date, (iii) of
      any Account arising after the Closing Date with respect to which the
      obligor thereon is a Governmental Authority and (iv) of the occurrence of
      any other event which could reasonably be expected to have a material
      adverse effect on the aggregate value of the Collateral or on the Liens
      created hereunder.

            (j) Changes in Locations, Name, etc. The Grantor will not (i) change
      the location of its chief executive office/chief place of business from
      that specified in Section 4(g) or remove its books and records from the
      location specified in Section 4(c), (ii) permit any of the Inventory or
      Equipment to be kept at a location other than that specified in Section
      4(f) or (iii) change its name, identity or corporate structure to such an
      extent that any financing statement filed by the Collateral Agent in
      connection with this Amended and Restated Security Agreement would become
      misleading, unless it shall have given the Collateral Agent at least 30
      days' prior written notice thereof.

            (i) The Grantor (either itself or through licensees) will (a) employ
      each Copyright with appropriate copyright notice consistent with its past
      practice and (b) not knowingly (and not permit any licensee or sublicensee
      thereof knowingly to) do any act or knowingly omit to do any act whereby
      any Copyright or any portion of the Copyright may become invalidated.

          (ii) The Grantor will not (either itself or through licensees)

      portion of the Copyrights may become injected into the public domain.

         (iii) The Grantor shall notify the Collateral Agent immediately if it
      knows, or has reason to know, that any Copyright or any portion of the
      Copyrights may become injected into the public domain or of any adverse
      determination (including, without limitation, the institution of, or any
      such determination or development in, any court or tribunal in the United
      States or any other country) regarding the Grantor's ownership of any
      Copyright or any portion of the Copyrights.

          (iv) The Grantor will, with respect to any Copyright that the Grantor
      registers after the Closing Date or any Copyright License that the Grantor
      knowingly acquires after the Closing Date, promptly (i) take all actions
      necessary so that the Collateral Agent shall obtain a perfected security
      interest in such Copyright or Copyright License and (ii) provide to the
      Collateral Agent a revised Schedule I hereto listing all registered
      Copyright and all Copyright Licenses owned by the Grantor.

          (v) On each December 31 of each year following the Date of the Initial
      Closing (or, if the Collateral Agent so requests in writing, more often),
      the Grantor either itself or through any agent, employee, licensee or
      designee, shall provide to the Collateral Agent a document confirming the
      Collateral Agent's security interest in all Copyrights and Copyright
      Licenses acquired by the Grantor during the preceding calendar year. Upon
      request of the Collateral Agent, the Grantor shall execute and deliver any
      and all additional agreements, instruments, documents, and papers as the
      Collateral Agent may reasonably request to confirm the Collateral Agent's
      security interest in such Copyrights and Copyright Licenses, and the
      Grantor hereby constitutes the Collateral Agent its attorney-in-fact to
      file all such writings for the foregoing purposes, all lawful acts of such

<PAGE>   13
      being coupled with an interest is irrevocable until the Obligations are

      without limitation, filing of applications for renewal, where necessary.

         (vii) The Grantor will promptly notify the Collateral Agent of any
      infringement of any Copyright or any portion of the Copyrights of which it

            (i) The Grantor (either itself or through licensees) will, with
respect to each Trademark, (i) continue to use such Trademark to the extent
necessary to maintain such Trademark in full force free from any claim of
abandonment for non-use, if consistent with its overall business plan or if to
do otherwise would be an unsound commercial and business judgment, (ii) maintain
as in the past the quality of products and services offered under such
Trademark, (iii) employ such Trademark with the appropriate notice of
registration, (iv) not (and not permit any licensee or sublicensee thereof to)
do any act or knowingly omit to do any act whereby any Trademark may become
invalidated other than solely (x) through the discontinuance of the sale of
goods or the provision of services or (y) the abandonment of a Trademark where,
in each such case covered by (x) and (y) above, the Collateral Agent shall have
received not less than fifteen (15) days' prior written notice of any such
discontinuance or abandonment and the Grantor shall have acted in a manner
consistent with its overall business plan and the exercise of sound commercial
and business judgment. Nothing in this Amended and Restated Security Agreement
shall restrict the Grantor from adding new goods and services to its business
or, upon not less than fifteen (15) days' prior written notice to the Collateral
Agent and in a manner consistent with the Grantor's overall business plan and
the exercise of sound commercial and business judgment, discontinuing the
provision of goods or services and thereby abandoning any Trademark relating

          (ii) The Grantor will notify the Collateral Agent immediately if it
knows, or has reason to know, that any application or registration relating to
any Trademark may become abandoned, or of any adverse determination or
development (including, without limitation, the institution of, or any such
determination


                                       13
<PAGE>   14
or development in, any proceeding in the United States Patent and Trademark
Office or any court or tribunal in any country) regarding the Grantor's
ownership of any Trademark or its right to register the same or to keep and
maintain the same.

         (iii) The Grantor will, with respect to any Trademark that the Grantor
registers after the Closing Date or any Trademark License that the Grantor
acquires after the Closing Date, promptly (i) take all actions necessary so that
the Collateral Agent shall obtain a perfected security interest in such
Trademark or Trademark License and (ii) provide to the Collateral Agent a
revised Schedule II hereto listing all registered Trademarks and all Trademark
Licenses owned by the Grantor.

          (iv) On each December 31 of each year following the Date of the
Initial Closing (or, if the Collateral Agent so requests in writing, more
often), the Grantor either itself or through any agent, employee, licensee or
designee, shall provide to the Collateral Agent, a document confirming the
Collateral Agent's security interest in any Trademark with respect to which the
Grantor has filed an application for registration during the preceding calendar
year. Upon request of the Collateral Agent, the Grantor shall execute and
deliver any and all agreements, instruments, documents, and papers as the
Collateral Agent may request to evidence the Collateral Agent's security
interest in any Trademark and the goodwill and general intangibles of the
Grantor relating thereto or represented thereby, and the Grantor hereby
constitutes the Collateral Agent its attorney-in-fact to execute and file all
such writings for the foregoing purposes, all acts of such attorney being hereby
ratified and confirmed; such power being coupled with an interest is irrevocable
until the Obligations are paid in full.

           (v) The Grantor will take all reasonable and necessary steps,
including, without limitation, in any proceeding before the United States Patent
and Trademark office, or any similar office or agency in any other country or
any political subdivision thereof, to maintain and pursue each application (and
to obtain the relevant registration) and to maintain each registration of the
Trademarks, including, without limitation, filing of applications for renewal,
affidavits of use and affidavits of incontestability. Notwithstanding the
foregoing, the Grantor may decline to maintain and pursue each application and
decline to maintain each registration as aforesaid upon not less than fifteen
(15) days' prior written notice to the Collateral Agent and if so to decline is
consistent with the Grantor's overall business plan and is an exercise of sound
commercial and business judgment.

          (vi) In the event that any Trademark included in the Collateral is
infringed, misappropriated or diluted by a third party, the Grantor shall
promptly notify the Collateral Agent


                                       14
<PAGE>   15
after it learns thereof and shall promptly take all appropriate steps to stop
the infringement as are reasonably mutually agreed upon by the Grantor and the
Collateral Agent.

            (m) Patents

            (i) The Grantor will notify the Collateral Agent immediately if it
knows, of has reason to know, that any application relating to any Patent may
become abandoned or of any adverse determination or development (including,
without limitation, the institution of, or any such determination or development
in, any proceeding in the United States Patent and Trademark Office or any court
or tribunal in any country) regarding the Grantor's ownership of any Patent.

          (ii) The Grantor will, with respect to any Patent that the Grantor
obtains after the Date of the Initial Closing or any Patent License that the
Grantor acquires after the Date of the Initial Closing, promptly (i) take all
actions necessary so that the Collateral Agent shall obtain a perfected security
interest in such Patent or Patent License and (ii) provide to the Collateral
Agent a revised Schedule II hereto listing all Patents and all Patent Licenses
owned by the Grantor.

         (iii) On each December 31 of each year following the Date of the
Initial Closing (or, if the Collateral Agent so requests in writing, more
often), the Grantor either itself or through any agent, employee, licensee or
designee, shall provide to the Collateral Agent, a document confirming the
Collateral Agent's security interest in any Patent or Patent License which the
Grantor has obtained during the preceding calendar year. Upon request of the
Collateral Agent, the Grantor shall execute and deliver any and all agreements,
instruments, documents, and papers as the Collateral Agent may request to
evidence the Collateral Agent's security interest in such Patents or Patent
Licenses, and the Grantor hereby constitutes the Collateral Agent its
attorney-in-fact to execute and file all such writings for the foregoing
purposes, all acts of such attorney being hereby ratified and confirmed; such
power being coupled with an interest is irrevocable until the Obligations are
paid in full.

         (iv) The Grantor will take all reasonable and necessary steps,
including, without limitation, in any proceeding before the United States Patent
and Trademark office, or any similar office or agency in any other country or
any political subdivision thereof, to maintain and pursue each patent or
application for patent and to maintain each Patent, including, without
limitation, payment of maintenance fees. Notwithstanding the foregoing, the
Grantor may decline to maintain and pursue each patent and application for
patent and decline to maintain each Patent as aforesaid upon not less than
fifteen (15) days' prior written notice to the Collateral Agent and if so to
decline is


                                       15
<PAGE>   16
consistent with the Grantor's overall business plan and is an exercise of sound
commercial and business judgment.

        (v) In the event that any Patent included in the Collateral is infringed
by a third party, the Grantor shall promptly notify the Collateral Agent after
it learns thereof and shall promptly take all appropriate steps to stop the
infringement as are reasonably mutually agreed upon by the Grantor and the
Collateral Agent.

            (n) Patent Licenses

            The Grantor shall comply with its obligations under each of its
Patent License Agreements.

            6. Collateral Agent's Appointment as Attorney-in-Fact.

            (a) Powers. The Grantor hereby irrevocably constitutes and appoints
the Collateral Agent and any officer or agent thereof, with full power of
substitution, as its true and lawful attorney-in-fact with full irrevocable
power and authority in the place and stead of the Grantor and in the name of the
Grantor or in its own name, from time to time (in the Collateral Agent's
discretion) for the purpose of carrying out the terms of this Amended and
Restated Security Agreement, to take any and all appropriate action and to
execute any and all documents and instruments which may be necessary or
desirable to accomplish the purposes of this Amended and Restated Security
Agreement, and, without limiting the generality of the foregoing, the Grantor
hereby gives the Collateral Agent the power and right, on behalf of the Grantor,
without notice to or assent by the Grantor, except any notice required by law
referred to in Section 9 hereof, to do the following:

            (i) at any time when any Event of Default shall have occurred and is
      continuing, in the name of the Grantor or its own name, or otherwise, to
      take possession of and indorse and collect any checks, drafts, notes,
      acceptances or other instruments for the payment of moneys due under any
      Account, Instrument, General Intangible or Contract or with respect to any
      other Collateral and to file any claim or to take any other action or
      proceeding in any court of law or equity or otherwise deemed appropriate
      by the Collateral Agent for the purpose of collecting any and all such
      moneys due under any Account, Instrument, General Intangible or Contract
      or with respect to any other Collateral whenever payable;

          (ii) to pay or discharge taxes and Liens levied or placed on or
      threatened against the Collateral, to effect any repairs or any insurance
      called for by the terms of this


                                       16
<PAGE>   17
      Amended and Restated Security Agreement and to pay all or any part of the
      premiums therefor and the costs thereof; and

         (iii) upon the occurrence and during the continuance of any Event of
      Default, (A) to direct any party liable for any payment under any of the
      Collateral to make payment of any and all moneys due or to become due
      thereunder directly to the Collateral Agent or as the Collateral Agent
      shall direct; (B) to ask or demand for, collect, receive payment of and
      receipt for, any and all moneys, claims and other amounts due or to become
      due at any time in respect of or arising out of any Collateral; (C) to
      sign and indorse any invoices, freight or express bills, bills of lading,
      storage or warehouse receipts, drafts against debtors, assignments,
      verifications, notices and other documents in connection with any of the
      Collateral; (D) to commence and prosecute any suits, actions or
      proceedings at law or in equity in any court of competent jurisdiction to
      collect the Collateral or any thereof and to enforce any other right in
      respect of any Collateral; (E) to defend any suit, action or proceeding
      brought against the Grantor with respect to any Collateral; (F) to settle,
      compromise or adjust any suit, action or proceeding described in clause
      (E) above and, in connection therewith, to give such discharges or
      releases as the Collateral Agent may deem appropriate; (G) to assign any
      Copyright or Trademark (along with the goodwill of the business to which
      any such Copyright or Trademark pertains), throughout the world for such
      term or terms, on such conditions, and in such manner, as the Collateral
      Agent shall in its sole discretion determine; and (H) generally, to sell,
      transfer, pledge and make any agreement with respect to or otherwise deal
      with any of the Collateral as fully and completely as though the
      Collateral Agent were the absolute owner thereof for all purposes, and to
      do, at the Collateral Agent's option and the Grantor's expense, at any
      time, or from time to time, all acts and things which the Collateral Agent
      deems necessary to protect, preserve or realize upon the Collateral and
      the Collateral Agent's Liens thereon and to effect the intent of this
      Amended and Restated Security Agreement, all as fully and effectively as
      the Grantor might do.

The Grantor hereby ratifies all that said attorneys shall lawfully do or cause
to be done by virtue hereof. This power of attorney is a power coupled with an
interest and shall be irrevocable until the Obligations are paid in full.

            (b) Other Powers. The Grantor also authorizes the Collateral Agent,
at any time and from time to time, to execute, in connection with the sale
provided for in Section 9 hereof, any endorsements, assignments or other
instruments of conveyance or transfer with respect to the Collateral.


                                       17
<PAGE>   18
            (c) No Duty on Collateral Agent's Part. The powers conferred on the
Collateral Agent hereunder are solely to protect the Collateral Agent's
interests in the Collateral and shall not impose any duty upon the Collateral
Agent to exercise any such powers. The Collateral Agent shall be accountable
only for amounts that it actually receives as a result of the exercise of such
powers, and neither it nor any of its officers, directors, employees or agents
shall be responsible to the Grantor for any act or failure to act hereunder,
except for their own gross negligence or willful misconduct.

            7. Performance by Collateral Agent of Grantor's Obligations. If the
Grantor fails to perform or comply with any of its agreements contained herein
and the Collateral Agent, as provided for by the terms of this Amended and
Restated Security Agreement, shall itself perform or comply, or otherwise cause
performance or compliance, with such agreement, the expenses of the Collateral
Agent incurred in connection with such performance or compliance, together with
interest thereon at a rate per annum specified in the last sentence of the first
paragraph of the Notes, shall be payable by the Grantor to the Collateral Agent
on demand and shall constitute Obligations secured hereby.

            8. Proceeds. In addition to the rights of the Collateral Agent
specified in Section 3(d) with respect to payments of Accounts, it is agreed
that if an Event of Default shall occur and be continuing (a) all Proceeds
received by the Grantor consisting of cash, checks and other instruments shall
be held by the Grantor in trust for the Collateral Agent, segregated from other
funds of the Grantor, and shall, forthwith upon receipt by the Grantor, be
turned over to the Collateral Agent in the exact form received by the Grantor
(duly indorsed by the Grantor to the Collateral Agent, if required), and (b) any
and all such Proceeds received by the Collateral Agent (whether from the Grantor
or otherwise) may, in the sole discretion of the Collateral Agent, be held by
the Collateral Agent as collateral security for, and/or then or at any time
thereafter may be applied by the Collateral Agent against, the Obligations
(whether matured or unmatured), such application to be in such order as the
Collateral Agent shall elect. Any balance of such Proceeds remaining after the
Obligations shall have been paid in full shall have been terminated shall be
paid over to the Grantor or to whomsoever may be lawfully entitled to receive
the same.

            9. Remedies. If an Event of Default shall occur and be continuing,
the Collateral Agent may exercise, in addition to all other rights and remedies
granted to them in this Amended and Restated Security Agreement and in any other
instrument or agreement securing, evidencing or relating to the Obligations, all
rights and remedies of a secured party under the Code. Without limiting the
generality of the foregoing, the Collateral Agent, without demand of performance
or other demand, present-


                                       18
<PAGE>   19
ment, protest, advertisement or notice of any kind (except any notice required
by law referred to below) to or upon the Grantor or any other Person (all and
each of which demands, defenses, advertisements and notices are, to the extent
permitted by applicable law, hereby waived), may in such circumstances forthwith
collect, receive, appropriate and realize upon the Collateral, or any part
thereof, and/or may forthwith sell, lease, assign, give option or options to
purchase, or otherwise dispose of and deliver the Collateral or any part thereof
(or contract to do any of the foregoing), in one or more parcels at public or
private sale or sales, at any exchange, broker's board or office of the
Collateral Agent or elsewhere upon such terms and conditions as it may deem
advisable and at such prices as it may deem best, for cash or on credit or for
future delivery without assumption of any credit risk. The Collateral Agent
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 the whole or
any part of the Collateral so sold, free of any right or equity of redemption in
the Grantor, which right or equity is hereby waived, to the extent permitted by
applicable law, or released. The Grantor further agrees, at the Collateral
Agent's request, to assemble the Collateral and make it available to the
Collateral Agent at places which the Collateral Agent shall reasonably select,
whether at the Grantor's premises or elsewhere. The Collateral Agent shall apply
the net proceeds of any such collection, recovery, receipt, appropriation,
realization or sale, after deducting all costs and expenses of every kind
incurred therein or incidental to the care or safekeeping of any of the
Collateral or in any way relating to the Collateral or the rights of the
Collateral Agent hereunder, including, without limitation, reasonable attorneys'
fees and disbursements, to the payment in whole or in part of the Obligations,
in such order as the Collateral Agent may elect, and only after such application
and after the payment by the Collateral Agent of any other amount required by
any provision of law, including, without limitation, Section 9-504(1)(c) of the
Code, need the Collateral Agent account for the surplus, if any, to the Grantor.
To the extent permitted by applicable law, the Grantor waives all claims,
damages and demands it may acquire against the Collateral Agent arising out of
the exercise by them of any 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 10 days before such sale or
other disposition. The Grantor 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 Collateral Agent to collect such deficiency.

            In furtherance, but not in limitation of, the foregoing, if an Event
of Default shall occur and be continuing, the Grantor shall assign, license, or
sublicense, as requested by


                                       19
<PAGE>   20
Collateral Agent, any or all of the Patent Licenses to the Collateral Agent.

            10. Limitation on Duties Regarding Preservation of Collateral. The
Collateral Agent's sole duty with respect to the custody, safekeeping and
physical preservation of the Collateral in its possession, under Section 9-207
of the Code or otherwise, shall be to deal with it in the same manner as the
Collateral Agent deals with similar property for its own account. Neither the
Collateral Agent, 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 Grantor or
otherwise.

            11. Powers Coupled with an Interest. All authorizations and agencies
herein contained with respect to the Collateral are irrevocable and powers
coupled with an interest until the Obligations are indefeasibly paid in full.

            12. Severability. Any provision of this Amended and Restated
Security Agreement which is prohibited or unenforceable in any jurisdiction
shall, as to such jurisdiction, be ineffective to the extent of such prohibition
or unenforceability without invalidating the remaining provisions hereof, and
any such prohibition or unenforceability in any jurisdiction shall not
invalidate or render unenforceable such provision in any other jurisdiction.

            13. Paragraph Headings. The paragraph headings used in this Amended
and Restated Security Agreement are for convenience of reference only and are
not to affect the construction hereof or be taken into consideration in the
interpretation hereof.

            14. No Waiver; Cumulative Remedies. The Collateral Agent shall not
by any act (except by a written instrument pursuant to Section 15 hereof),
delay, indulgence, omission or otherwise be deemed to have waived any right or
remedy hereunder or to have acquiesced in any Default or Event of Default or in
any breach of any of the terms and conditions hereof. No failure to exercise,
nor any delay in exercising, on the part of the Collateral Agent, 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 Collateral Agent of any right or remedy hereunder on
any one occasion shall not be construed as a bar to any right or remedy which
the Collateral Agent would otherwise have on any future occasion. The rights and
remedies herein provided are cumulative, may be exercised


                                       20
<PAGE>   21
singly or concurrently and are not exclusive of any rights or remedies provided
by law.

            15. Waivers and Amendments; Successors and Assigns. None of the
terms or provisions of this Amended and Restated Security Agreement may be
waived, amended, supplemented or otherwise modified except by a written
instrument executed by the Grantor and the Collateral Agent, provided that any
provision of this Amended and Restated Security Agreement may be waived by the
Collateral Agent in a written letter or agreement executed by the Collateral
Agent or by facsimile transmission from the Collateral Agent. This Amended and
Restated Security Agreement shall be binding upon the successors and assigns of
the Grantor and shall inure to the benefit of the Collateral Agent and its
successors and assigns.

            16. Termination of Security Interest; Release of Collateral. (a)
Upon the repayment in full of all Obligations, the security interest granted in
the Collateral pursuant to this Agreement (the "Security Interest") shall
terminate and all rights to the Collateral shall revert to the Grantor.

            (b) Upon any such termination of the Security Interest or release of
Collateral pursuant to this Section , the Collateral Agent will, at the expense
of the Grantor, execute and deliver to the Grantor such documents as the Grantor
shall reasonably request to evidence the termination of the Security Interest
and deliver to the Grantor all Collateral so released then in its possession.

            17. Notices. All notices or other communications provided for
hereunder shall be in writing and sent by first class mail or nationwide
overnight delivery service, if to Grantor, addressed to it at 8140 Walnut Hill
Lane, Suite 1000, Dallas, Texas 75321, Attention: Michael G. Pate, or at such
other address as the Grantor shall have specified to the Collateral Agent in
