Debtor and for other good and valuable consideration,  and  as security for the
performance by Debtor of its obligations under the Notes and  as  security  for
the repayment of the Loans and all other sums due from Debtor to Lender arising
under  the  Loan  Agreement,  and  any  other  agreement  between or among them
inclusive  of  the  items and matters described as "Obligations"  in  the  Loan
Agreement (collectively,  the  "Obligations"),  Debtor,  for  good and valuable
consideration,  receipt of which is acknowledged, has agreed to  grant  to  the

Agreement, Collateral shall not include  any  personal property which is, or at
the time of a Debtor's acquisition thereof is or  becomes subject to a purchase
money  mortgage  or other purchase money lien or security  interest  (including

            (C)   All Receivables as defined in the Loan Agreement.

      3.3   The Lender is hereby  specifically  authorized,  after the Maturity
Date  (defined  in the Notes) accelerated or otherwise, or after  an  Event  of
Default (as defined  herein)  and the expiration of any applicable cure period,
to transfer any Collateral into  the name of the Lender and to take any and all
action  deemed advisable to the Lender  to  remove  any  transfer  restrictions
affecting the Collateral.

4.    Perfection of Security Interest.

      4.1   Debtor  shall  prepare,  execute  and  deliver  to the Lender UCC-1
Financing Statements.  The Lender is instructed to prepare and file at Debtor's
cost and expense, financing statements in such jurisdictions  deemed  advisable
to the Lender, including but not limited to the States of Nevada and Texas.

      4.2   The Debtor shall promptly deliver to Lender, upon Lender's request,
stock certificates representing all of the shares of outstanding capital  stock
of the Debtor (the "Securities").  All such certificates shall be held by or on
behalf  of  Lender  pursuant hereto and shall be delivered in suitable form for
transfer by delivery,  or  shall be accompanied by duly executed instruments of
transfer or assignment or undated  stock  powers executed in blank, all in form
and substance satisfactory to Lender.

      4.3      All other certificates and instruments  constituting  Collateral
from time to time required to be pledged to Lender pursuant to the terms hereof
(the "Additional  Collateral")  shall  be  delivered  to  Lender  promptly upon
receipt  thereof  by  or  on  behalf  of  Debtor.   All  such  certificates and
instruments shall be held by or on behalf of Lender pursuant hereto  and  shall
be delivered in suitable form for transfer by delivery, or shall be accompanied
by  duly executed instruments of transfer or assignment or undated stock powers
executed  in  blank,  all in form and substance satisfactory to Lender.  If any
Collateral  consists  of  uncertificated  securities,  unless  the  immediately
following sentence is applicable  thereto,  Debtor  shall  cause Lender (or its
custodian, nominee or other designee) to become the registered  holder thereof,
or  cause  each  issuer  of  such securities to agree that it will comply  with
instructions originated by Lender  with  respect  to  such  securities  without
further   consent   by   Debtor.    If  any  Collateral  consists  of  security
entitlements, Debtor shall transfer such  security  entitlements  to Lender (or
its  custodian,  nominee  or other designee) or cause the applicable securities
intermediary to agree that  it  will  comply  with entitlement orders by Lender
without further consent by Debtor.

      4.4   Within  five  (5)  days  after  the receipt  by  a  Debtor  of  any
Additional Collateral, a Pledge Amendment, duly  executed  by  such  Debtor, in
substantially  the  form  of  Annex  I hereto (a "Pledge Amendment"), shall  be
delivered  to Lender in respect of the  Additional  Collateral  to  be  pledged
pursuant to  this  Agreement.  Debtor  hereby  authorizes Lender to attach each
Pledge  Amendment  to  this  Agreement  and  agrees that  all  certificates  or
instruments listed on any Pledge Amendment delivered  to  Lender  shall for all
purposes hereunder constitute Collateral.

      4.5   If  Debtor shall receive, by virtue of Debtor being or having  been
an owner of any Collateral,  any  (i)  stock  certificate  (including,  without
limitation,  any  certificate representing a stock dividend or distribution  in
connection with any increase or reduction of capital, reclassification, merger,
consolidation, sale  of assets, combination of shares, stock split, spin-off or
split-off), promissory  note or other instrument, (ii) option or right, whether
as an addition to, substitution  for,  or  in  exchange for, any Collateral, or
otherwise, (iii) dividends payable in cash (except  such dividends permitted to
be retained by Debtor pursuant to Section 5.2 hereof) or in securities or other
property or (iv) dividends or other distributions in  connection with a partial
or  total  liquidation  or  dissolution or in connection with  a  reduction  of
capital, capital surplus or paid-in  surplus,  Debtor  shall receive such stock
certificate,   promissory   note,   instrument,  option,  right,   payment   or
distribution  in trust for the benefit  of  Lender,  shall  segregate  it  from
Debtor's other  property and shall deliver it forthwith to Lender, in the exact
form received, with  any  necessary endorsement and/or appropriate stock powers
duly executed in blank, to  be  held  by  Lender  as  Collateral and as further
collateral security for the Obligations.

5.    Distribution.

      5.1   So long as an Event of Default or a Default (as defined in the Loan
Agreement)  does  not exist, Debtor shall be entitled to  exercise  all  voting
power pertaining to  any  of  the  Collateral,  provided  such  exercise is not
contrary to the interests of the Lender and does not impair the Collateral.

      5.2.  At any time an Event of Default exists or has occurred,  all rights
of  Debtor,  upon  notice  given  by  Lender,  to exercise the voting power and
receive payments, which it would otherwise be entitled  to  pursuant to Section
5.1, shall cease and all such rights shall thereupon become vested  in  Lender,
which  shall  thereupon  have  the sole right to exercise such voting power and
receive such payments.

      5.3   All dividends, distributions, interest and other payments which are
received by Debtor contrary to the  provisions of Section 5.2 shall be received
in trust for the benefit of Lender as  security  and  Collateral for payment of
the Obligations shall be segregated from other funds of  Debtor,  and  shall be
forthwith paid over to Lender as Collateral in the exact form received with any
necessary  endorsement  and/or appropriate stock powers duly executed in blank,
to be held by Lender as Collateral  and  as further collateral security for the
Obligations.

6.    Further Action By Debtor; Covenants and Warranties.

      6.1   Lender at all times shall have a perfected security interest in the
Collateral, the Securities, Additional Collateral (the "Perfected Collateral").
Debtor has and will continue to have full title to the Collateral free from any
liens,  leases, encumbrances, judgments or  other  claims.   Lender's  security
interest in the Collateral constitutes and will continue to constitute a first,
prior and  indefeasible  security  interest in favor of Lender.  Debtor will do
all acts and things, and will execute  and file all instruments (including, but
not  limited  to,  security  agreements,  financing   statements,  continuation
statements,  etc.)  reasonably requested by Lender to establish,  maintain  and
continue the perfected security interest of Lender in the Perfected Collateral,
and  will promptly on  demand,  pay  all  costs  and  expenses  of  filing  and
recording,  including  the costs of any searches reasonably deemed necessary by
Lender from time to time  to  establish  and  determine  the  validity  and the
continuing priority of the security interest of Lender, and also pay all  other
claims and charges that, in the opinion of Lender, exercised in good faith, are
reasonably  likely  to  materially  prejudice,  imperil or otherwise affect the
Collateral or Lender's security interests therein.

      6.2   Other than in the ordinary course of  business,  for fair value and
in cash, and except for Collateral which is substituted by assets  of identical
or  greater  value (with the consent of the Lender) or which is inconsequential
in value, Debtor  will  not  sell,  transfer,  assign  or pledge those items of
Collateral  (or  allow  any  such  items to be sold, transferred,  assigned  or
pledged), without the prior written  consent of Lender other than a transfer of
the Collateral to a wholly-owned United  States formed and located wholly-owned
subsidiary or to another Debtor on prior notice  to  Lender,  and  provided the
Collateral remains subject to the security interest herein described.  Although
Proceeds  of  Collateral  are  covered  by  this  Agreement, this shall not  be
construed to mean that Lender consents to any sale of the Collateral, except as
provided herein.  Sales of Collateral in the ordinary  course of business shall
be  free of the security interest of Lender and Lender shall  promptly  execute
such   documents   (including   without  limitation  releases  and  termination
statements) as may be required by Debtor to evidence or effectuate the same.

      6.3   Debtor will, at all reasonable  times during regular business hours
and  upon  reasonable  notice,  allow Lender or its  representatives  free  and
complete access to the Collateral and all of such Debtor's records which in any
way relate to the Collateral, for  such  inspection  and  examination as Lender
reasonably deems necessary.

      6.4   Debtor, at its sole cost and expense, will protect  and defend this
Security  Agreement, all of the rights of Lender hereunder, and the  Collateral
against the claims and demands of all other persons.

      6.5   Debtor  will promptly notify Lender of any levy, distraint or other
seizure by legal process or otherwise of any part of the Collateral, and of any
threatened or filed claims  or proceedings that are reasonably likely to affect
or impair any of the rights of  Lender  under  this  Security  Agreement in any
material respect.

      6.6   Debtor,  at  its  own  expense, will obtain and maintain  in  force
insurance policies covering losses or damage to those items of Collateral which
constitute physical personal property,  which  insurance  shall be of the types
customarily  insured  against  by  companies  in the same or similar  business,
similarly  situated,  in  such amounts (with such  deductible  amounts)  as  is
customary for such companies under the same or similar circumstances, similarly
situated.  Debtor shall make  the  Lender a loss payee thereon to the extent of
its  interest  in  the Collateral. Lender  is  hereby  irrevocably  (until  the
Obligations are paid  in  full)  appointed Debtor's attorney-in-fact to endorse
any check or draft that may be payable  to  such  Debtor  so  that  Lender  may
collect  the  proceeds payable for any loss under such insurance.  The proceeds
of such insurance,  less  any  costs and expenses incurred or paid by Lender in
the collection thereof, shall be  applied  either toward the cost of the repair
or replacement of the items damaged or destroyed,  or  on  account  of any sums
secured hereby, whether or not then due or payable.

      6.7   Lender  may,  at its option, and without any obligation to  do  so,
pay, perform and discharge any and all amounts, costs, expenses and liabilities
herein agreed to be paid or  performed  by Debtor.  Upon Debtor's failure to do
so,  all  amounts expended by Lender in so  doing  shall  become  part  of  the
Obligations  secured hereby, and shall be immediately due and payable by Debtor
to Lender upon demand and shall bear interest at the lesser of 15% per annum or
the highest legal amount from the dates of such expenditures until paid.

      6.8   Upon  the  request  of Lender, Debtor will furnish to Lender within
five (5) business days thereafter, or to any proposed assignee of this Security
Agreement, a written statement in  form reasonably satisfactory to Lender, duly
acknowledged, certifying the amount of the principal and interest and any other
sum then owing under the Obligations,  whether  to  its  knowledge  any claims,
offsets  or  defenses  exist  against  the Obligations or against this Security
Agreement, or any of the terms and provisions  of any other agreement of Debtor
securing the Obligations.  In connection with any  assignment by Lender of this
Security  Agreement,  Debtor  hereby  agrees  to cause the  insurance  policies
required  hereby  to  be carried by Debtor, if any,  to  be  endorsed  in  form
satisfactory to Lender  or to such assignee, with loss payable clauses in favor
of such assignee, and to  cause  such  endorsements  to  be delivered to Lender
within ten (10) calendar days after request therefor by Lender.

      6.9   Debtor   will,   at  its  own  expense,  make,  execute,   endorse,
acknowledge, file and/or deliver to the Lender from time to time such vouchers,
invoices,   schedules,   confirmatory   assignments,   conveyances,   financing
statements, transfer endorsements,  powers  of  attorney, certificates, reports
and other reasonable assurances or instruments and  take further steps relating
to the Collateral and other property or rights covered by the security interest
hereby granted, as the Lender may reasonably require  to  perfect  its security
interest hereunder.

      6.10  Debtor  represents  and  warrants  that  it  is the true and lawful
exclusive   owner  of  the  Collateral,  free  and  clear  of  any  liens   and
encumbrances.

      6.11  Debtor  hereby  agrees  not to divest itself of any right under the
Collateral except as permitted herein  absent  prior  written  approval  of the
Lender.

      6.12  Debtor  shall  cause  each Subsidiary of Debtor in existence on the
date hereof and each Subsidiary not  in existence on the date hereof to execute
and deliver to Lender promptly and in  any  event  within  10  days  after  the
formation,  acquisition or change in status thereof (A) a guaranty guaranteeing
the Obligations and (B) if requested by Lender, a security and pledge agreement
substantially  in  the  form  of  this Agreement together with (x) certificates
evidencing all of the capital stock  of each Subsidiary of and any entity owned
by such Subsidiary, (y) undated stock  powers executed in blank with signatures
guaranteed, and (z) such opinion of counsel  and  such approving certificate of
such Subsidiary as Lender may reasonably request in  respect  of complying with
any legend on any such certificate or any other matter relating  to such shares
and (C) such other agreements, instruments, approvals, legal opinions  or other
documents reasonably requested by Lender in order to create, perfect, establish
the first priority of or otherwise protect any lien purported to be covered  by
any  such  pledge and security agreement or otherwise to effect the intent that
all property  and  assets  of  such  Subsidiary shall become Collateral for the
Obligations.  For purposes of this Agreement,  "Subsidiary" means, with respect
to  any entity at any date, any corporation, limited  or  general  partnership,
limited  liability  company, trust, estate, association, joint venture or other
business entity) of which  more  than  50% of (A) the outstanding capital stock
having (in the absence of contingencies)  ordinary  voting  power  to  elect  a
majority  of  the  board  of  directors  or other managing body of such entity,
(B) in the case of a partnership or limited  liability company, the interest in
the  capital or profits of such partnership or  limited  liability  company  or
(C) in the case of a trust, estate, association, joint venture or other entity,
the beneficial  interest  in  such  trust,  estate, association or other entity
business  is, at the time of determination, owned  or  controlled  directly  or
indirectly  through one or more intermediaries, by such entity.  As of the date
of this Agreement,  Debtor  has no Subsidiaries.  Debtor will promptly complete
and deliver to lender Annex I hereto upon the acquisition of each Subsidiary.

7.    Power of Attorney.

      At any time an Event of  Default  exists  or  has occurred, Debtor hereby
irrevocably constitutes and appoints the Lender as the true and lawful attorney
of  Debtor, with full power of substitution, in the place  and  stead  of  such
Debtor  and  in  the name of such Debtor or otherwise, at any time or times, in
the discretion of  the Lender, to take any action and to execute any instrument
or document which the  Lender may deem necessary or advisable to accomplish the
purposes of this Agreement.  This power of attorney is coupled with an interest
and is irrevocable until the Obligations are indefeasibly satisfied.

8.    Performance By The Lender.

      If a Debtor fails  to  perform  any material covenant, agreement, duty or
obligation  of such Debtor under this Agreement,  the  Lender  may,  after  any
applicable cure  period, at any time or times in its discretion, take action to
effect performance  of  such obligation.  All reasonable expenses of the Lender
incurred in connection with  the  foregoing  authorization  shall be payable by
Debtor as provided in Paragraph 12.1 hereof.  No discretionary right, remedy or
power granted to the Lender under any part of this Agreement shall be deemed to
impose  any  obligation  whatsoever  on  the Lender with respect thereto,  such
rights, remedies and powers being solely for the protection of the Lender.

9.    Event of Default.

      An event of default ("Event of Default") shall be deemed to have occurred
hereunder upon the occurrence of any event  of default as defined and described
in this Agreement, in the Notes, the Loan Agreement, Transaction Documents, and
any other agreement to which Debtor and Lender  are  parties.    Upon and after
any Event of Default, after the applicable cure period, if any, any  or  all of
the  Obligations shall become immediately due and payable at the option of  the
Lender,  and the Lender may dispose of Collateral as provided below.  A default
by Debtor  of  any  of its material obligations pursuant to this Agreement, the
Loan Agreement and such other agreements shall be an Event of Default hereunder
and an "Event of Default" as defined in the Loan Agreement.

10.   Disposition of Collateral.

      Upon and after any Event of Default which is then continuing,

      10.1  The Lender  may  exercise its rights with respect to each and every
component of the Collateral, without  regard  to  the  existence  of  any other
security or source of payment for the Obligations.  In addition to other rights
and remedies provided for herein or otherwise available to it, the Lender shall
have  all  of  the rights and remedies of a lender on default under the Uniform
Commercial Code then in effect in the State of New York.

      10.2  If any  notice  to  Debtor  of  the  sale  or  other disposition of
Collateral  is required by then applicable law, five business  (5)  days  prior
written notice  (which  Debtor agree is reasonable notice within the meaning of
Section 9.612(a) of the Uniform  Commercial  Code)  shall be given to Debtor of
the time and place of any sale of Collateral which Debtor  hereby  agree may be
by private sale.  The rights granted in this Section are in addition to any and
all rights available to Lender under the Uniform Commercial Code.

      10.3  The Lender is authorized, at any such sale, if the Lender  deems it
advisable to do so, in order to comply with any applicable securities laws,  to
restrict  the  prospective  bidders or purchasers to persons who will represent
and agree, among other things,  that  they  are  purchasing  the Collateral for
their  own  account for investment, and not with a view to the distribution  or
resale thereof,  or otherwise to restrict such sale in such other manner as the
Lender deems advisable  to  ensure such compliance.  Sales made subject to such
restrictions shall be deemed  to  have  been  made in a commercially reasonable
manner.

      10.4  All  proceeds  received  by the Lender  in  respect  of  any  sale,
collection or other enforcement or disposition  of Collateral, shall be applied
(after  deduction of any amounts payable to the Lender  pursuant  to  Paragraph
12.1 hereof)  against  the  Obligations.   Upon indefeasible payment in full of
all Obligations, Debtor shall  be  entitled  to  the  return of all Collateral,
including  cash,  which  has  not been used or applied toward  the  payment  of
Obligations or used or applied  to  any and all costs or expenses of the Lender
incurred in connection with the liquidation  of  the Collateral (unless another
person  is  legally entitled thereto).  Any assignment  of  Collateral  by  the
Lender to Debtor  shall  be  without  representation  or warranty of any nature
whatsoever and wholly without recourse.  To the extent  allowed  by law, Lender
may purchase the Collateral and pay for such purchase by offsetting  up to such
Lender's portion of the purchase price with sums owed to such Lender by  Debtor
arising under the Obligations or any other source.

11.   Waiver of Automatic Stay.   Debtor acknowledges and agrees that should  a
proceeding  under  any  bankruptcy or insolvency law be commenced by or against
Debtor, or if any of the Collateral should become the subject of any bankruptcy
or insolvency proceeding,  then  the  Lender should be entitled to, among other
relief to which the Lender may be entitled  under  the  Loan  Agreement and any
other agreement to which the Debtor and Lender are parties, (collectively "Loan
Documents")  and/or applicable law, an order from the court granting  immediate
relief from the  automatic stay pursuant to 11 U.S.C. Section 362 to permit the
Lender to exercise  all  of  its  rights  and  remedies  pursuant  to  the Loan
Documents  and/or  applicable law.  Debtor EXPRESSLY WAIVES THE BENEFIT OF  THE
AUTOMATIC STAY IMPOSED BY 11 U.S.C. SECTION 362.  FURTHERMORE, Debtor EXPRESSLY
ACKNOWLEDGES AND AGREES  THAT  NEITHER  11  U.S.C.  SECTION  362  NOR ANY OTHER
SECTION  OF  THE  BANKRUPTCY CODE OR OTHER STATUTE OR RULE (INCLUDING,  WITHOUT
LIMITATION, 11 U.S.C.  SECTION 105) SHALL STAY, INTERDICT, CONDITION, REDUCE OR
INHIBIT IN ANY WAY THE ABILITY  OF  THE LENDER TO ENFORCE ANY OF ITS RIGHTS AND
REMEDIES  UNDER  THE  LOAN  DOCUMENTS AND/OR  APPLICABLE  LAW.   Debtor  hereby
consents to any motion for relief from stay which may be filed by the Lender in
any bankruptcy or insolvency  proceeding  initiated  by  or against Debtor, and
further agrees not to file any opposition to any motion for  relief  from  stay
filed  by  the  Lender.   Debtor  represents, acknowledges and agrees that this
provision is a specific and material  aspect  of  this  Agreement, and that the
Lender would not agree to the terms of this Agreement if this waiver were not a
part  of  this Agreement.  Debtor further represents, acknowledges  and  agrees
that this waiver is knowingly, intelligently and voluntarily made, that neither
the Lender  nor  any  person  acting  on  behalf  of  the  Lender  has made any
representations to induce this waiver, that Debtor has been represented (or has
had the opportunity to be represented) in the signing of this Agreement  and in
the  making of this waiver by independent legal counsel selected by Debtor  and
that Debtor  has  had  the  opportunity  to  discuss  this waiver with counsel.
Debtor further agrees that any bankruptcy or insolvency proceeding initiated by
Debtor will only be brought in the Federal Court within  the  Southern District
of New York.

12.   Miscellaneous.

      12.1  Expenses.  Debtor shall pay to the Lender, on demand, the amount of
any  and  all  reasonable  expenses, including, without limitation,  attorneys'
fees,  legal  expenses  and brokers'  fees,  which  the  Lender  may  incur  in
connection with (a) sale,  collection  or  other  enforcement or disposition of
Collateral; (b) exercise or enforcement of any the  rights,  remedies or powers
of  the Lender hereunder or with respect to any or all of the Obligations  upon
breach  or  threatened  breach; or (c) failure by Debtor to perform and observe
any agreements of Debtor contained herein which are performed by the Lender.

      12.2  Waivers, Amendment  and  Remedies.   No  course  of  dealing by the
Lender  and  no  failure  by the Lender to exercise, or delay by the Lender  in
exercising, any right, remedy  or  power  hereunder  shall  operate as a waiver
thereof, and no single or partial exercise thereof shall preclude  any other or
further exercise thereof or the exercise of any other right, remedy or power of
the  Lender.   No  amendment,  modification or waiver of any provision of  this
Agreement and no consent to any  departure  by  Debtor therefrom, shall, in any
event, be effective unless contained in a writing  signed  by  the  Lender, and
then  such  waiver  or consent shall be effective only in the specific instance
and for the specific  purpose for which given.  The rights, remedies and powers
of  the  Lender,  not only  hereunder,  but  also  under  any  instruments  and
agreements evidencing  or securing the Obligations and under applicable law are
cumulative, and may be exercised  by the Lender from time to time in such order
as the Lender may elect.

      12.3  Notices.   All  notices  or  other  communications  given  or  made
hereunder  shall be in writing and shall  be  personally  delivered  or  deemed
