Lenders (which representations and warranties  will  survive  the  creation  and
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.


                                   ARTICLE IV

                            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  Louisiana  and  Texas 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  Parish  Clerk  of  Bienville
Parish,  Louisiana  and  of  the  Secretary  of  State  of  Texas.   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
financing statement or other public notices or recordings,

                                      -7-

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(a)(ix),
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.

    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)  With respect to Collateral located in any jurisdiction:

         (i)    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.

         (ii)   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.

         (iii)  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

                                      -12-

    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  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.

         (iv)   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.

         (v)    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.

         (vi)   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.

         (vii)  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;

                                      -13-

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

         (viii) 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.

         (ix)   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.

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

    (b)  With respect to any Collateral located in  Louisiana,  Secured  Party's
rights shall also include the following:

         (i)    Secured  Party,  at  its  option,  may  declare  all Obligations
    immediately  due  and  payable  or   performable  and  Secured  Party  shall
    thereupon, in addition to the rights and remedies provided in this  Security
    Agreement  or  in  any other instrument or document executed by Debtor, have
    all the rights and remedies of  a "secured party" under Louisiana Commercial
    Laws (La. R.S. 10:9-101 et seq.) and under  all  other  applicable  laws  of
    Louisiana  or any other state having jurisdiction.  Secured Party shall have
    the right to sell,  transfer  or  otherwise  dispose  of  any and all of the
    Collateral and to apply the proceeds thereof toward payment  of  all  costs,
    expenses,  attorney's  fees  and  legal expenses thereby incurred by Secured
    Party and toward payment and performance of the

                                      -14-

    Obligations in such order or manner  as Secured Party may elect.  Unless the
    Collateral threatens to decline speedily in value, Secured Party shall  send
    Debtor  reasonable notice of the time and place of any public sale or of the
    time after which any private sale or  the disposition thereof is to be made.
    The requirement of sending a reasonable notice shall be met if  such  notice
    is  mailed,  postage  prepaid,  to  Debtor  at  the address set forth on the
    signature page hereof at least  fifteen  (15)  days  before the time of such
    sale or  disposition.   All  expenses  of  retaking,  holding,  maintaining,
    preparing  for  sale,  selling  and  the  like,  including  Secured  Party's
    reasonable  attorney's  fees and legal expenses, shall constitute additional
    Obligations of Debtor and shall be  immediately due and payable, and payment
    of the same shall be secured  by  and  entitled  to  the  benefits  of  this
    Security Agreement.  If the proceeds of any sale or other lawful disposition
    of  the  Collateral  by  Secured  Party  are  insufficient  to fully pay the
    Obligations, then Debtor shall pay or cause to be paid any deficiency.

         (ii)   Debtor agrees that, in the event any proceedings are taken under
    this Security Agreement by way  of  executory  process or otherwise, any and
    all declarations of fact made by authentic act before a notary public and in
    the presence of two witnesses by person declaring that such facts lie within
    his knowledge shall constitute authentic evidence of such facts for purposes
    of executory process, and in connection with any such action to foreclose or
    otherwise realize upon the Collateral.

         (iii)  Debtor expressly waives:

              (A)  The benefit of appraisement provided for  in  Articles  2332,
         2336,  2723, 2724, Louisiana Code of Civil Procedure and all other laws
         conferring such benefits.

              (B)  The demand and three  days'  delay  accorded by Articles 2639
         and 2721, Louisiana Code of Civil Procedure.

              (C)  The three days' delay provided by  Articles  2331  and  2722,
         Louisiana Code of Civil Procedure.

              (D)  The  benefit  of  the other provisions of Articles 2331, 2722
         and 2723, Louisiana Code of Civil Procedure; Debtor expressly agrees to
         the immediate seizure of the Collateral in the event of suit hereon.

         (iv)   Debtor does further confess judgment  for the full amount of the
    Obligations in principal, interest, attorneys' fees and all other costs  and
    charges  and does consent and agree that upon the occurrence of any Event of
    Default, Secured Party may cause all of the Collateral to be seized and sold
    under executory or any other legal process, at the option of Secured Party.

                                      -15-

         (v)    Notwithstanding  anything  to  the  contrary  contained  in this
    Article VI or elsewhere in this Security Agreement,  the  Obligations  shall
    immediately   become   fully  due,  payable,  performable,  satisfiable  and
    dischargeable without the necessity of further action on the part of Secured
    Party, and Debtor hereby expressly  waives  any required notice of intent to
    accelerate the Obligations and notice of acceleration of the Obligations.

    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.

    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

                                      -16-

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 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

                                      -17-

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,  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

                                      -18-

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 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
change statement filed or  registered  or  verification  statement issued at any
time in respect of this Security Agreement.
