payment of the Obligations) that:

    Section 3.01   First  Priority Security Interest.  The grant of the security
interest in the Collateral pursuant  to  this Security Agreement creates a valid
and perfected first priority security interest in  the  Collateral,  enforceable
against Debtor and all third parties and securing payment of the Obligations.

    Section 3.02   No Filings By Third Parties.  No financing statement or other
public  notice  or  recording  covering  the Collateral is on file in any public
office (other than any financing  statement  or other public notice or recording
naming Secured Party as the secured party therein), and Debtor will not  execute
any  such financing statement or other public notice or recording so long as any
of the Obligations are outstanding.

    Section 3.03   No Name Changes.  Debtor  has  not, during the preceding five
years, entered into  any  contract,  agreement,  security  instrument  or  other
document  using  a  name other than, or been known by or otherwise used any name
other than, the name used by Debtor herein.

    Section 3.04   Location of Debtor  and Collateral.  Debtor's chief executive
office and Debtor's records concerning the Collateral are located at the address
or location set forth on the signature page hereof.  The Collateral  is  located
at  such  address  or at the location(s), if any, specified in Exhibit A hereto.
Any Collateral not at such  location(s)  nevertheless remains subject to Secured
Party's security interest.

    Section 3.05   Collateral.  All statements or other information provided  by
Debtor  to  Secured  Party,  any  Issuing Bank or any Lender with respect to the
Collateral is or (in  the  case  of  subsequently furnished information) will be
when provided correct and complete in all material respects.   The  delivery  at
any  time  by  Debtor to Secured Party of additional Collateral or of additional
descriptions of Collateral shall constitute a representation and warranty by

                                      -4-

Debtor to Secured Party  hereunder  that  the  representations and warranties of
this Article III are correct insofar as they would pertain to such Collateral or
the descriptions thereof.

    Section 3.06   Accounts.

    (a)  Each Account represents the  genuine,  valid  and  legally  enforceable
indebtedness  of  an Account Debtor arising from the sale, lease or rendition by
Debtor of goods or  services  and  is  not  and  will  not  be subject to contra
accounts, set-offs, defenses, counterclaims, allowances  or  adjustments  (other
than  discounts  for  prompt  payment  shown  on  the invoice), or objections or
complaints by the Account Debtor  concerning  its  liability on the Account; and
any goods, the sale of which gave rise to an Account, have not been returned  or
rejected  by  the  Account  Debtor  or  lost  or damaged prior to receipt by the
Account Debtor.

    (b)  The amount shown as to each Account on Debtor's books is or will be the
true and undisputed amount  owing  and  unpaid  thereon.  Except as disclosed in
writing to Secured Party, each  Account  arose  or  shall  have  arisen  in  the
ordinary course of Debtor's business; provided, however, that any Accounts which
arose  or hereafter arise outside the ordinary course of Debtor's business shall
nevertheless be included as part of  the Collateral.  Debtor has no knowledge of
any bankruptcy, insolvency or other  action  affecting  creditors'  rights  with
respect to any Account Debtor.

    (c)  Except  as  disclosed  in  writing  to  Secured  Party, each invoice or
agreement evidencing the Accounts is or will be due and payable not more than 90
days from the date thereof; provided, however,  that any Accounts not so due and
payable shall nevertheless be included as part of the Collateral.

    Section 3.07   Delivery of Documents or Letters of Credit.  With respect  to
any  Inventory  or other Collateral covered by one or more certificates of title
or other documents evidencing ownership  or possession thereof, and with respect
to any Accounts or other Collateral supported by letters of credit, each of such
certificates, documents or letters of credit has been delivered to Secured Party
(provided, however, that all  certificates,  documents  and  letters  of  credit
referred to in Section 1.02 shall be subject to the security interest created by
this  Security Agreement irrespective of whether or not such delivery shall have
been made).

    Section 3.08   Ownership  of  Collateral;  Encumbrances;  Valid  and Binding
Agreement.  Debtor is the legal and beneficial owner of the Collateral free  and
clear  of  any adverse claim, lien, security interest, option or other charge or
encumbrance except for the  security  interest  created  by this Agreement or as
permitted by the  Credit  Agreement,  and  Debtor  has  full  right,  power  and
authority  to  assign and grant a security interest in the Collateral to Secured
Party.  This Agreement  constitutes  a  legal,  valid  and binding obligation of
Debtor enforceable against Debtor in accordance with its terms.  The  execution,
delivery  and  performance  of  this Agreement will not violate the terms of any
contract, agreement, law,  regulation,  order,  injunction,  judgment, decree or
writ to which Debtor is subject and does not require the consent or approval  of
any other Person.

                                      -5-

    Section 3.09   No  Required Consent.  No authorization, consent, approval or
other action by, and no notice to  or filing with, any governmental authority or
regulatory body (other than the filing of financing statements) is required  for
(i)  the  due  execution,  delivery and performance by Debtor of this Agreement,
(ii) the grant by Debtor  of  the  security  interest granted by this Agreement,
(iii) the perfection of such security interest or (iv) the exercise  by  Secured
Party of its rights and remedies under this Agreement.

                            Covenants and Agreements

    Debtor  covenants and agrees that so long as any part of the Obligations are
outstanding:

    Section 4.01   Change in Location of Collateral or Debtor.  Debtor will give
Secured Party 30 days' prior written notice of (i) any change in location of the
Collateral to a jurisdiction  other  than  Texas,  Alaska, California, Oregon or
Washington and which would cause the Secured Party  to  be  unperfected  in  the
Collateral,  (ii)  the  opening  or closing of any place of Debtor's business or
(iii) any change in the location of Debtor's chief executive office or address.

    Section 4.02   Documents; Collateral  in  Possession  of  Third Parties.  If
certificates of title or other documents evidencing ownership or  possession  of
the  Collateral  are  issued  or  outstanding,  Debtor  will  cause the security
interest of Secured Party to be  properly noted thereon and will, forthwith upon
receipt, deliver same to Secured Party.  If any Collateral is at any time in the
possession  or  control  of  any  warehouseman,  bailee,  agent  or  independent
contractor, Debtor shall notify such Person of Secured Party's security interest
in such Collateral.  Upon Secured Party's request,  Debtor  shall  instruct  any
such  Person  to hold all such Collateral for Secured Party's account subject to
Debtor's instructions, or, if an  Event  of Default shall have occurred, subject
to Secured Party's instructions.

    Section 4.03   Delivery of Letters  of  Credit  and  Instruments;  Proceeds.
Debtor will deliver each letter of credit, if any, included in the Collateral to
Secured  Party,  in  each  case  forthwith upon receipt by or for the account of
Debtor.  If any Account becomes evidenced by a promissory note, trade acceptance
or any other instrument for the payment of money (other than checks or drafts in
payment of Accounts collected by Debtor in the ordinary course of business prior
to notification by Secured  Party  under  Section 5.04), Debtor will immediately
deliver such instrument to  Secured  Party  appropriately  endorsed  to  Secured
Party,  as  collateral  assignee  and,  regardless  of  the form of presentment,
demand, notice of dishonor, protest and  notice of protest with respect thereto,
Debtor will remain liable thereon until such instrument is paid in full.  Except
as permitted by Sections 4.03, 4.08 and 4.09, Debtor  will  deliver  to  Secured
Party all proceeds from the sale or other disposition of the Collateral promptly
upon  receipt.   If  chattel  paper,  documents  or  instruments are received as
proceeds, which are required to  be  delivered  to  Secured Party, they will be,
immediately upon receipt, properly endorsed or assigned and delivered to Secured
Party as Collateral.

                                      -6-

    Section 4.04   Sale, Disposition or Encumbrance of Collateral.   Except  (i)
as  permitted  by  Section  4.08,  or (ii) with the prior written consent of the
Majority Lenders, Debtor will not in any  way encumber any of the Collateral (or
permit or suffer any of the Collateral to be encumbered) or sell, assign,  lend,
rent,  lease  or otherwise dispose of or transfer any of the Collateral to or in
favor of any Person other than Secured Party.

    Section 4.05   Intentionally left blank.

    Section 4.06   Records and Information.

    (a)  Debtor shall  keep  accurate  and  complete  records  of the Collateral
(including proceeds).  These records shall reflect complete and  accurate  stock
records  of  the  Inventory and all facts concerning each Account.  Debtor shall
conduct a physical count of  the  Inventory  at  such intervals as Secured Party
requests and promptly supply Secured Party with a copy of such count accompanied
by a report of the value (valued at the lower of cost or market  value)  of  the
Inventory.   Secured  Party may at any time have access to, examine, audit, make
extracts from and inspect without hindrance or delay Debtor's records, files and
the Collateral.

    (b)  Debtor will promptly furnish such information as Secured Party may from
time to time reasonably request regarding (i) the business, affairs or financial
condition of Debtor or (ii) the Collateral or Secured Party's rights or remedies
with respect thereto.  Any balance  sheets  or financial statements requested by
Secured Party pursuant to  this  Section  4.06(b)  shall  conform  to  generally
accepted accounting principles.

    (c)  Debtor   recognizes   that   financing  statements  pertaining  to  the
Collateral will be filed with the  offices  of  the Secretary of State of Texas,
the  Alaska  Department  of  Natural  Resources,  the  Secretary  of  State   of
California,  the Secretary of State of Oregon and the Department of Licensing of
the State of Washington.  Debtor  will  immediately  notify Secured Party of any
condition or event that may change the proper location for  the  filing  of  any
financing  statements  or  other  public notice or recordings for the purpose of
perfecting  a  security  interest  in  the  Collateral.   Without  limiting  the
generality of the foregoing, Debtor will (i) immediately notify Secured Party of
any change to a jurisdiction other  than  as  represented in Section 3.04 (A) in
the location of Debtor's chief executive office or chief place of business,  (B)
in  the  location  of  the  office where Debtor keeps its records concerning the
Accounts, or (C) in  the  "location"  of  Debtor  within  the meaning of Section
9-103(c) of the Code; (ii) immediately notify Secured Party of any change in the
location of the Collateral to any jurisdiction other than the States  of  Texas,
Alaska, California, Oregon and Washington; and (ii) notify Secured Party 30 days
prior  to  any  change  in Debtor's name, identity or corporate structure or Tax
Identification Number.  In  any  notice  furnished  pursuant  to this paragraph,
Debtor will expressly state  that  the  notice  is  required  by  this  Security
Agreement  and  contains  facts  that  will or may require additional filings of
financing statements or other notices  for  the purpose of continuing perfection
of Secured Party's security interest in the Collateral.   Debtor  will  promptly
provide  written  notice  to  Secured  Party of all information which in any way
relates to  or  affects  the  Collateral  generally,  Secured  Party's rights or
remedies with respect thereto, the filing of any

                                      -7-

financing statement or other public notices or recordings, or the  delivery  and
possession  of  items  of  Collateral  for  the purpose of perfecting a security
interest in the Collateral.

    Section 4.07   Further  Assurances.   Upon  the  request  of  Secured Party,
Debtor shall (at Debtor's expense) execute and  deliver  all  such  assignments,
certificates,   financing   statements  or  other  documents  and  give  further
assurances and do all  other  acts  and  things  as Secured Party may reasonably
request to perfect Secured Party's interest in the  Collateral  or  to  protect,
enforce or otherwise effect Secured Party's rights and remedies hereunder.

    Section 4.08   Inventory.   Unless  an  Event of Default has occurred and is
continuing and after any applicable notice  and cure periods provided for in the
Credit Agreement, Debtor  may  use  the  Inventory  in  any  lawful  manner  not
inconsistent  with  this  Security  Agreement  and  with  the terms of insurance
thereon and may sell, lease or  otherwise  dispose  of its Inventory for cash or
terms in the ordinary course of business, and Debtor may retain the proceeds  of
such  sales,  leases  or other dispositions (subject to Section 4.03 and Section
4.09); provided, however, the Inventory  shall remain in Debtor's possession and
control at all times prior to sale,  lease  or  other  disposition  at  Debtor's
address  set  forth  in Section 3.04.  Debtor shall bear any risk of loss of the
Inventory.  Debtor shall not use any  item of Inventory in a manner inconsistent
with the holding thereof for sale, lease or other disposition  in  the  ordinary
course  of business or in contravention of the terms of any agreement.  Upon the
occurrence and continuance of an Event  of Default and after any applicable cure
period, Debtor shall immediately deliver to Secured Party any  checks,  cash  or
other  forms  of payment which Debtor receives in connection with any Inventory,
appropriately endorsed.

    Section 4.09   Accounts.

    (a)  Prior to notification by  Secured  Party  under Section 6.02(i), Debtor
will collect the Accounts in the ordinary course of its business and may  retain
the proceeds of such collections (subject to Section 4.03).

    (b)  Debtor  shall  immediately notify Secured Party in writing in the event
that any representation given in Article  III with respect to any Account ceases
to be true and correct in all material respects; such  notice  specifying  other
representation(s) that cease to be true and correct and the action, if any, that
Debtor proposes to take with respect thereto.

    (c)  Debtor will not modify, extend or substitute any contract, the terms of
which  shall  at  any time have given rise to an Account, except in the ordinary
course of business or with the  prior  written consent of Secured Party.  Debtor
will not re-date any invoice or sale or make sales with an extended payment date
beyond that customary in the industry, and in no  event  longer  than  90  days.
Debtor  shall  not  adjust,  settle, discount or compromise any of the Accounts,
except in the ordinary course of  business, as permitted by the Credit Agreement
or with the prior written consent of Secured Party.

                                      -8-

    (d)  Debtor will duly perform or cause  to  be  performed  all  of  Debtor's
obligations  with  respect  to the Accounts and the underlying sales of goods or
other transactions giving rise to the Accounts.

    Section 4.10   Condition of Collateral.  Debtor will maintain all Collateral
in good condition  and  in  accordance  with  industry  standards and practices.
Debtor will not misuse, abuse, waste, destroy or  endanger  the  Collateral  nor
allow  it to be used in any manner other than its intended use.  Debtor will not
use any Collateral in violation of any Governmental Requirement, or suffer it to
be so used.

    Section 4.11   Collateral Separate and Distinct.   Debtor shall at all times
keep the Collateral, including proceeds, or cause it to be  kept  (when  in  the
possession  of  warehousemen,  bailees, agents, independent contractors or other
third parties), separate and  distinct  from  other Property; provided, however,
proceeds of the Collateral may be kept in various concentration accounts of  the
Parent or the Guarantors.

    Section 4.12   Change in Debtor's Name  or Corporate Structure.  Debtor will
not change  its  name,  identity  or  corporate  structure  (including,  without
limitation,  any  merger,  consolidation  or  sale  of  substantially all of its
assets) without notifying Secured Party  of  such  change in writing at least 30
days prior to the effective date of such change.  Without  the  express  written
consent  of Secured Party, however, Debtor will not engage in any other business
or transaction under any name other than Debtor's name hereunder.

         (a)  obtain, adjust, sell and cancel any insurance with respect to  the
    Collateral  and  endorse  any draft drawn by insurers of the Collateral, and
    Secured Party may apply any proceeds  or unearned premiums of such insurance
    to the Obligations (whether or not due); and

                                      -9-

         (b)  take any  action  and  to  execute  any  assignment,  certificate,
    financing  statement,  notification,  document  or  instrument which Secured
    Party may deem necessary  or  advisable  to  accomplish the purposes of this
    Security Agreement, including, without limitation, to receive,  endorse  and
    collect  all  instruments made payable to Debtor representing any payment or
    other distribution in respect of the  Collateral  or any part thereof and to
    give full discharge for the same.

    Section 5.02   Transfer of Collateral.  Secured Party may  transfer  any  or
all  of  the Obligations, and upon any such transfer, Secured Party may transfer
its interest in any  or  all  of  the  Collateral  and shall be fully discharged
thereafter from all liability therefor.  Any transferee of the Collateral  shall
be vested with all rights, powers and remedies of Secured Party hereunder.

    Section 5.03   Purchase Money Financing.   To  the  extent  that the Lenders
have advanced or will advance funds to or for the account of  Debtor  to  enable
Debtor  to  purchase or otherwise acquire specific types or items of Collateral,
the Lenders may at their option pay  such  funds (i) directly to the Person from
whom Debtor will make such purchase or acquire such rights or (ii) to Debtor, in
which case Debtor covenants  promptly  to  pay  the  same  to  such  Person  and
forthwith furnish to Secured Party, on request, evidence satisfactory to Secured
Party  that  such  payment  has  been made from the funds so provided by Secured
Party for such payment.

    Section 5.04   Proceeds.  If so requested  by  Debtor, any payments received
by Secured Party on the Accounts or as proceeds of other Collateral  shall  upon
final   collection   by  Secured  Party  be  credited  towards  payment  of  the
Obligations.   In  the  absence  of  such  request  from  Debtor,  and  until so
requested, Secured Party may hold such collected  payments  as  cash  Collateral
(and  Secured  Party  may at any time place a hold or freeze on all or a part of
any deposit account of Debtor  containing  deposits  of  such payments up to the
amount of such deposits).

    Section 5.05   Discharge Encumbrances.   Secured  Party  may, at its option,
discharge any taxes, Liens, security interests or other encumbrances at any time
levied or placed on the Collateral, may pay for insurance on the Collateral  and
may  pay  for the maintenance and preservation of the Collateral.  Debtor agrees
to reimburse Secured Party upon demand for any payment so made, plus interest on
the portion thereof from time to time  remaining unpaid from the date of Secured
Party's demand at the rate for overdue  principal  and  interest  set  forth  in
Section 2.06(c) of the Credit Agreement.

    Section 5.06   Disclaimer of Certain Duties.

    (a)  The  powers conferred upon Secured Party by this Security Agreement are
to protect the interest of Secured  Party,  the Issuing Banks and the Lenders in
the Collateral and shall not impose any duty upon  Secured  Party,  the  Issuing
Banks  or  any  Lender  to  exercise any such powers.  Debtor hereby agrees that
Secured  Party,  the  Issuing Banks and the Lenders shall not be liable for, nor
shall the indebtedness evidenced by the Obligations be diminished by,

                                      -10-

Secured  Party's  delay  or  failure  to  collect  upon,  foreclose,  sell, take
possession of or otherwise obtain value for the Collateral.

    (b)  Except  as  provided  in  the  Credit Agreement, Secured Party shall be
under no duty whatsoever to  make  or  give any presentment, notice of dishonor,
protest, demand for performance, notice of non-performance, notice of intent  to
accelerate, notice of acceleration, or other notice or demand in connection with
any  Collateral  or  the Obligations, or to take any steps necessary to preserve
any rights against any Obligor, Account Debtor or other Person.

    Section 5.07   Modification of  Obligations;  Other Security.  Debtor waives
(i) any and all notice of  acceptance,  creation,  modification,  rearrangement,
renewal or extension for any period of any instrument executed by any Obligor in
connection with the Obligations and (ii) any defense of any Obligor by reason of
disability,  lack of authorization, cessation of the liability of any Obligor or
for any other reason.  Debtor authorizes Secured Party, without notice or demand
and without any  reservation  of  rights  against  Debtor  and without affecting
Debtor's liability hereunder or on the Obligations, from time  to  time  to  (x)
take  and  hold  other  Property, other than the Collateral, as security for the
Obligations, and  exchange,  enforce,  waive  and  release  any  or  all  of the
Collateral, (y) apply the Collateral in the manner permitted  by  this  Security
Agreement  and  (z)  renew,  extend for any period, accelerate, amend or modify,
supplement, enforce, compromise, settle, waive or release the obligations of any
Obligor or any instrument or agreement of  such other Person with respect to any
or all of the Obligations or Collateral.

    Section 5.08   Waiver of Notice; Demand and Presentment;  etc.   Except  for
any notice required under the Credit Agreement, Debtor hereby waives any demand,
notice  of  default,  notice of acceleration of the maturity of the Obligations,
notice of intent to  accelerate  the  maturity  of the Obligations, presentment,
protest and notice of dishonor as to  any  action  taken  by  Secured  Party  in
connection  with this Security Agreement, or any instrument or document.  Debtor
waives any right of marshaling in respect  of any and all Collateral, and waives
any right to require Secured Party, any Issuing Bank or any  Lender  to  proceed
against  any  Obligor, Account Debtor or other Person, exhaust any Collateral or
enforce any other remedy which Secured Party, any Issuing Bank or any Lender now
has or may hereafter have against any Obligor or other Person.

    Section 5.09   Non-judicial Enforcement.  To  the  fullest extent allowed by
applicable law, Secured Party may enforce its  rights  hereunder  without  prior
judicial process or judicial hearing, and to the fullest extent permitted by law
Debtor  expressly  waives any and all legal rights which might otherwise require
Secured Party to enforce its rights by judicial process.

                                      -11-

                                   ARTICLE VI

                               Events of Default

    Section 6.01   Events of  Default.   An  Event  of  Default under the Credit
Agreement shall constitute an "Event of Default" under this Security Agreement.

    Section 6.02   Remedies.  Upon the occurrence and during the continuance  of
any Event of Default, Secured Party may take any or all of the following actions
without  notice  (except  where expressly required under the Credit Agreement or
below) or demand to Debtor:

         (a)  Declare  all  or  part   of   the  indebtedness  pursuant  to  the
    Obligations immediately due and payable and enforce payment of the  same  by
    Debtor or any Obligor.

         (b)  Take  possession  of the Collateral, or at Secured Party's request
    Debtor  shall,  at  Debtor's  cost,  assemble  the  Collateral  and  make it
    available at a location to be specified by Secured Party which is reasonably
    convenient to Debtor and Secured Party.  In any event, Debtor shall bear the
    risk of accidental  loss  or  damage  to  or  diminution  in  value  of  the
    Collateral, and Secured Party shall have no liability whatsoever for failure
    to obtain or maintain insurance, nor to determine whether any insurance ever
    in force is adequate as to amount or as to risk insured.

         (c)  Sell or lease, in one or more  sales  or leases and in one or more
    parcels, or otherwise dispose of any or all of the Collateral  in  its  then
    condition  or  in  any other commercially reasonable manner as Secured Party
    may elect, in a public  or  private  transaction,  at any location as deemed
    reasonable  by  Secured  Party  (including,  without  limitation,   Debtor's
    premises), either for cash or credit or for future delivery at such price as
    Secured  Party may deem fair, and (unless prohibited by the Code, as adopted
    in any applicable  jurisdiction)  Secured  Party,  any  Issuing  Bank or any
    Lender may be the purchaser of any or all Collateral so sold and  may  apply
    upon  the  purchase price therefor any Obligations secured hereby.  Any such
    sale or transfer by Secured Party  either  to  itself or to any other Person
    shall be absolutely free from any claim of right by  Debtor,  including  any
    equity  or  right  of  redemption, stay or appraisal which Debtor has or may
    have under any rule of law,  regulation or statute now existing or hereafter
    adopted.  Upon any such sale or transfer, Secured Party shall have the right
    to deliver, assign and transfer to the purchaser or transferee  thereof  the
    Collateral  so  sold  or  transferred.   It  shall not be necessary that the
    Collateral or any part thereof be  present  at the location of any such sale
    or transfer.  Secured Party may, at its discretion,  provide  for  a  public
    sale,  and  any  such public sale shall be held at such time or times within
    ordinary business hours and at such place or places as Secured Party may fix
    in the notice of such sale.   Secured  Party  shall not be obligated to make
    any sale pursuant to any such notice.  Secured Party may, without notice  or
    publication,  adjourn any public or private sale by announcement at any time
    and place fixed for such sale,  and  such  sale  may  be made at any time or
    place to which the same may be so adjourned.   In  the  event  any  sale  or
    transfer hereunder is not

                                      -12-

    completed  or  is  defective  in  the opinion of Secured Party, such sale or
    transfer shall  not  exhaust  the  rights  of  Secured  Party hereunder, and
    Secured Party shall have the right to cause one or more subsequent sales  or
    transfers  to be made hereunder.  In the event that any of the Collateral is
    sold or transferred on credit,  or  to  be  held by Secured Party for future
    delivery to a purchaser or transferee, the Collateral so sold or transferred
    may be  retained  by  Secured  Party  until  the  purchase  price  or  other
    consideration  is  paid  by  the purchaser or transferee thereof, but in the
    event that such purchaser or transferee  fails  to pay for the Collateral so
    sold or transferred or to take delivery thereof, neither Secured Party,  any
    Issuing  Bank  nor  any  Lender  shall  incur  any  liability  in connection
    therewith.  If only part of the  Collateral is sold or transferred such that
    the Obligations remain outstanding (in whole or in  part),  Secured  Party's
    rights  and  remedies  hereunder shall not be exhausted, waived or modified,
    and Secured Party is specifically  empowered  to make one or more successive
    sales or transfers until all the Collateral shall be sold or transferred and
    all the Obligations are paid.  In the event that Secured Party elects not to
    sell the Collateral, Secured Party retains its rights to lease or  otherwise
    dispose  of  or  utilize  the Collateral or any part or parts thereof in any
    manner authorized or  permitted  by  law  or  in  equity,  and  to apply the
    proceeds of the same towards payment of the  Obligations.   Each  and  every
    method of disposition of the Collateral described in this Section 6.02(c) or
    in Section 6.02(f) shall constitute disposition in a commercially reasonable
    manner.

         (d)  Take  possession  of all books and records of Debtor pertaining to
    the Collateral.  Secured Party shall  have  the  authority to enter upon any
    real or immoveable property or improvements thereon in order to  obtain  any
    such  books  or  records,  or any Collateral located thereon, and remove the
    same therefrom without liability.

         (e)  Apply  proceeds  of  the  disposition  of  the  Collateral  to the
    Obligations in any manner elected by Secured Party and permitted by the Code
    or otherwise permitted by law or in equity.  Such application  may  include,
    without  limitation, the reasonable expenses of retaking, holding, preparing
    for sale or other disposition, and  the reasonable attorneys' fees and legal
    expenses incurred by Secured Party, the Issuing Banks and the Lenders.

         (f)  Appoint any Person as agent to perform any act or  acts  necessary
    or  incident  to  any  sale  or transfer by Secured Party of the Collateral.
    Additionally,  any  sale  or  transfer  hereunder  may  be  conducted  by an
    auctioneer or any officer or agent of Secured Party.

         (g)  Apply and set-off (i) any deposits of Debtor now or hereafter held
    by Secured Party, the Issuing Banks and the  Lenders;  (ii)  all  claims  of
    Debtor  against  Secured  Party,  now or hereafter existing; (iii) any other
    Property, rights or interests of  Debtor  which  come into the possession or
    custody or under the control of Secured Party; and (iv) the proceeds of  any
    of  the  foregoing  as if the same were included in the Collateral.  Secured
    Party agrees to notify Debtor promptly after any such set-off or

                                      -13-

    application; provided, however, the  failure  of  Secured  Party to give any
    notice shall not affect the validity of such set-off or application.

         (h)  With respect to the Collateral, receive, change  the  address  for
    delivery,  open  and  dispose  of  mail addressed to Debtor, and to execute,
    assign and endorse  negotiable  and  other  instruments  for  the payment of
    money, documents of title or other evidences of payment, shipment or storage
    for any form of Collateral on behalf of and in the name of Debtor.

         (i)  Notify or require  Debtor  to  notify  Account  Debtors  that  the
    Accounts have been assigned to Secured Party and direct such Account Debtors
    to  make  payments on the Accounts directly to Secured Party.  To the extent
    Secured Party does not so elect, Debtor shall continue to collect and retain
    the Accounts.  Secured Party or its  designee  shall also have the right, in
    its own name or in the name of Debtor, to do any of the following:   (i)  to
    demand,  collect,  receipt  for,  settle,  compromise  any amounts due, give
    acquittances for, prosecute or defend any action which may be in relation to
    any monies due or to become  due  by  virtue of, the Accounts; (ii) to sell,
    transfer or assign or otherwise deal in the Accounts or the proceeds thereof
    or the related goods, as fully and effectively as if Secured Party were  the
    absolute  owner  thereof;  (iii) to extend the time of payment of any of the
    Accounts, to grant waivers and  make  any allowance or other adjustment with
    reference thereto; (iv) to endorse the name of Debtor on  notes,  checks  or
    other  evidences  of payments on Collateral that may come into possession of
    Secured Party; (v)  to  take  control  of  cash  and  other  proceeds of any
    Collateral; (vi) to sign the name of Debtor on any invoice or bill of lading
    relating to any Collateral, or any drafts against Account Debtors  or  other
    persons  making  payment with respect to Collateral; (vii) to send a request
    for verification of Accounts to  any  Account  Debtor;  and (viii) to do all
    other acts and things necessary to carry out the intent of this Agreement.

         (j)  Exercise all other rights and remedies  permitted  by  law  or  in
    equity.

    Section 6.03   Liability   for Deficiency.  If any sale or other disposition
of Collateral by Secured  Party  or  any  Issuing  Bank  or  any other action of
Secured Party, any Issuing Bank or any Lender hereunder results in reduction  of
the  Obligations,  such  action  will  not  release Debtor from its liability to
Secured Party, the Issuing  Banks  and  the  Lenders for any unpaid Obligations,
including costs, charges and expenses incurred in the liquidation of Collateral,
together with interest thereon, and  the  same  shall  be  immediately  due  and
payable  to  Secured Party at Secured Party's address set forth on the signature
page of this Security Agreement.

    Section 6.04   Reasonable Notice.  If  any  applicable  provision of any law
requires Secured Party any Issuing Bank or any Lender to give reasonable  notice
of  any  sale  or disposition or other action, Debtor hereby agrees that fifteen
(15) days' prior  written  notice  shall  constitute  reasonable notice thereof.
Such notice, in the case of public sale, shall state the time  and  place  fixed
for  such  sale and, in the case of private sale, the time after which such sale
is to be made.

                                      -14-

    Section 6.05   Account Debtors.   Any  payment  or  settlement of an Account
made by an Account Debtor will be, to the extent  of  such  payment  or  to  the
extent  provided  under such settlement, a release, discharge and acquittance of
the Account Debtor with  respect  to  such  Account,  and  Debtor shall take any
action as may be required by Secured Party in connection therewith.  No  Account
Debtor  on  any Account will ever be bound to make inquiry as to the termination
of this Agreement or the rights of  Secured Party to act hereunder, but shall be
fully protected by Debtor in making payment directly to Secured Party.


                                  ARTICLE VIII

                                 Miscellaneous

    Section 7.01   Notices.  Any notice required or permitted to be given  under
or  in connection with this Security Agreement shall be given in accordance with
the notice provisions of the Guaranty Agreement.

    Section 7.02   Amendments and Waivers.   Secured Party's, any Issuing Bank's
or any Lender's acceptance of partial or delinquent payments or any forbearance,
failure or delay by the Secured Party in exercising any right, power  or  remedy
hereunder  shall  not  be  deemed  a  waiver  of any obligation of Debtor or any
Obligor, or of any  right,  power  or  remedy  of  Secured Party; and no partial
exercise of any right, power or remedy  shall  preclude  any  other  or  further
exercise thereof.  Secured Party may remedy any Event of Default hereunder or in
connection  with  the  Obligations  without  waiving  the  Event  of  Default so
remedied.  Debtor hereby agrees that if Secured  Party agrees to a waiver of any
provision hereunder, or an exchange of or release  of  the  Collateral,  or  the
addition  or  release  of  any  Obligor,  any such action shall not constitute a
waiver of  any  of  Secured  Party's  other  rights  or  of Debtor's obligations
hereunder.  This Security Agreement may be amended only by the manner set  forth
in  Section  9.02  of  the Credit Agreement by an instrument in writing executed
jointly by Debtor and Secured  Party  and  may be supplemented only by documents
delivered or to be delivered in accordance with the express terms hereof.

    Section 7.03   Copy  as  Financing  Statement.    A   photocopy   or   other
reproduction  of this Security Agreement or any financing statement covering the
Collateral is sufficient as a  financing  statement,  and  the same may be filed
with any appropriate filing authority for  the  purpose  of  perfecting  Secured
Party's security interest in the Collateral.

    Section 7.04   Possession  of  Collateral.  Secured Party shall be deemed to
have possession of any Collateral in transit  to  it or set apart for it (or, in
either case, any of its agents, affiliates or correspondents).

    Section 7.05   Redelivery  of  Collateral.   If  any  sale  or  transfer  of
Collateral by Secured Party results in full satisfaction of the Obligations, and
after such sale or transfer and discharge there remains a surplus  of  proceeds,
Secured Party will deliver to Debtor such excess proceeds

                                      -15-

in  a  commercially  reasonable  time;  provided,  however, that neither Secured
Party, any Issuing Bank nor any Lender shall be liable for any interest, cost or
expense in connection with any delay in delivering such proceeds to Debtor.

    Section 7.06   Governing Law; Jurisdiction.  This Security Agreement and the
security interest granted  hereby  shall  be  construed  in  accordance with and
governed by the laws of the State of Texas (except to the extent that  the  laws
of  any  other  jurisdiction  govern the perfection and priority of the security
interests granted  hereby).   Debtor  consents  to  and  submits  to in personam
jurisdiction and venue in the state district and county  courts  of  the  county
wherein  Secured  Party's  offices  are  located at the address specified on the
signature page hereof,  and  in  the  Federal  District  Courts  of the district
wherein  such  offices  of  Secured  Party  are  located.   This  submission  to
jurisdiction is nonexclusive and does not preclude Secured  Party,  any  Issuing
Bank  or any Lender from obtaining jurisdiction over Debtor or the Collateral in
any court otherwise having jurisdiction.

    Section 7.07   Cumulative and Other Rights.  The rights, powers and remedies
of Secured Party hereunder are  in  addition  to all rights, powers and remedies
given by law or in equity.  The exercise by Secured Party, any Issuing  Bank  or
any  Lender  of  any one or more of the rights, powers and remedies herein shall
not be  construed  as  a  waiver  of  any  other  rights,  powers  and remedies,
including, without limitation, any other rights  of  set-off.   If  any  of  the
Obligations  are given in renewal, extension for any period or rearrangement, or
applied toward the payment of debt secured  by any lien, Secured Party shall be,
and is hereby, subrogated  to  all  the  rights,  titles,  interests  and  liens
securing the debt so renewed, extended, rearranged or paid.

    Section 7.08   Subrogation.   Until  the Obligations have been paid in full,
Debtor hereby waives any claim,  right  or  remedy  which Debtor may now have or
hereafter acquire  against  the  Company  which  arises  out  of  this  Security
Agreement  or  from  the  performance  by  Debtor  hereunder,  including without
limitation,  any  claim,   remedy   or   right  of  subrogation,  reimbursement,
exoneration, indemnification, or participation  in  any  such  claim,  right  or
remedy   of   any   other   Person   against  the  Company;  provided,  however,
notwithstanding the foregoing, Debtor  reserves  its  rights of contribution and
reimbursement, if any, from any Obligor.  Until the Obligations have  been  paid
in  full,  Debtor  further waives any benefit of any right to participate in any
security now or hereafter held  by  Secured  Party, the Issuing Banks and/or the
Lenders.

    Section 7.09   Continuing Security Agreement.

    (a)  This  Security  Agreement  shall  constitute  a   continuing   security
agreement,  and  all  representations  and  warranties, covenants and agreements
shall, as applicable, apply  to  all  future  as  well as existing transactions.
Provisions of this Security Agreement, unless they are by their terms exclusive,
shall be in addition to other agreements between the parties.

    (b)  Except as may be expressly applicable  pursuant to Section 9.505 of the
Code, no action taken or omission to act by Secured Party, the Issuing Banks  or
the Lenders hereunder,

                                      -16-

including,  without limitation, any action taken or inaction pursuant to Section
6.02,  shall  be  deemed  to  constitute   a  retention  of  the  Collateral  in
satisfaction of the Obligations or otherwise to be in full satisfaction  of  the
Obligations,  and  the  Obligations shall remain in full force and effect, until
Secured Party, the Issuing  Banks  and  the  Lenders shall have applied payments
(including,  without  limitation,  collections  from  Collateral)  towards   the
Obligations in the full amount then outstanding or until such subsequent time as
is hereinafter provided in subsection (c) below.

    (c)  To  the  extent that any payments on the Obligations or proceeds of the
Collateral  are  subsequently   invalidated,   declared   to  be  fraudulent  or
preferential, set aside or required  to  be  repaid  to  a  trustee,  debtor  in
possession,  receiver  or  other  Person under any bankruptcy law, common law or
equitable cause, then  to  such  extent  the  Obligations  so satisfied shall be
revived and continue as if such payment or proceeds had  not  been  received  by
Secured  Party,  the  Issuing  Banks  or  the  Lenders, and Secured Party's, the
Issuing Banks' and the Lenders'  security interests, rights, powers and remedies
hereunder shall continue in full force and effect.  In such event, this Security
Agreement shall be automatically reinstated if it shall  theretofore  have  been
terminated pursuant to Section 7.10.

    (d)  In  the  event  that the Obligations are structured such that there are
times when no Indebtedness  is  owing  thereunder, this Security Agreement shall
remain valid and in full force and effect  as  to  all  subsequent  indebtedness
included  in  the  Obligations,  provided  Secured  Party has not in the interim
period  executed  a  written  release   or  termination  statement  or  returned
possession of or reassigned the Collateral to Debtor.

    Section 7.10   Termination.  The grant of a security interest hereunder  and
all  of  Secured Party's, the Issuing Banks' and the Lenders' rights, powers and
remedies in connection therewith  shall  remain  in  full force and effect until
Secured Party has retransferred and delivered all Collateral in  its  possession
to  Debtor,  and  executed  a  written  release  or  termination  statement  and
reassigned  to  Debtor without recourse or warranty any remaining Collateral and
all rights conveyed hereby.  Upon  the  complete  payment of the Obligations and
the compliance by Debtor with  all  covenants  and  agreements  hereof,  Secured
Party,  at the written request and expense of Debtor, will release, reassign and
transfer the Collateral to Debtor and  declare  this Security Agreement to be of
no further force or effect.  Notwithstanding the foregoing,  the  provisions  of
Section 7.09(c) shall survive the termination of this Security Agreement.

    Section 7.11   Counterparts,  Effectiveness.  This Security Agreement may be
executed in two or more  counterparts.   Each counterpart is deemed an original,
but all such counterparts taken together constitute one and the same instrument.
This Security Agreement becomes effective upon the execution  hereof  by  Debtor
and  delivery  of the same to Secured Party, and it is not necessary for Secured
Party, the Issuing Banks  or  any  Lender  to  execute  any acceptance hereof or
otherwise signify or express its acceptance hereof.

    Section 7.12   Headings Descriptive.  All titles or  headings  to  articles,
sections,  subsections  or  other  divisions  of  this Security Agreement or the
exhibits hereto are only for the

                                      -17-

convenience of the parties and  shall  not  be  construed  to have any effect or
meaning  with  respect  to  the  other  content  of  such  articles,   sections,
subsections  or  other divisions, such other content being controlling as to the
agreement between the parties hereto.

    Section 7.13   Delivery  of  Copy/Waiver.   The  Debtor  hereby acknowledges
receiving a copy of this Security Agreement.  The Debtor waives  all  rights  to
receive  from  the  Secured Party a copy of any financing statement or financing
