      ($5,000,000).

2.    BORROWER'S  NOTES.  The  indebtedness  shall be evidenced by the following
      credit facilities:

      2.1   Term Note I.  Promissory Note of even date herewith in the principal
            face  amount  of  THREE  MILLION  FIVE  HUNDRED   THOUSAND   DOLLARS
            ($3,500,000.00) ("Term Note I"), which will be in form and substance
            and payable on the terms  approved by Lender.  Interest only will be
            paid monthly on the 15th day of each month  commencing May 15, 2003,
            and ending on August 15, 2003. Thereafter, the Borrower will make 31
            equal  monthly  payments  on the 15th day of each month in an amount
            sufficient to fully  amortize  principal and interest on Term Note I
            over 72 months. Term Note I shall mature and become due on April 15,
            2006, at which time, the Borrower will make a balloon payment of the
            entire  outstanding  principal  balance  together  with all  accrued
            interest and other charges, if any.

      2.2   Term Note II. Promissory Note of even date herewith in the principal
            face amount of FIVE HUNDRED  THOUSAND DOLLARS  ($500,000.00)  ("Term

            15, 2004. Term Note II shall mature and become due on the earlier of
            receipt by the Borrower of proceeds from the Private  Offering in an
            amount equal to or greater  than  $1,000,000  or April 15, 2004.  At
            maturity,  the Borrower  will pay the entire  outstanding  principal
            balance  together with all accrued  interest and other  charges,  if
            any.

      2.3   Revolving  Line of Credit.  The Lender will  provide the  Borrower a
            revolving line of credit as follows:

            2.3.1 Note.  Promissory  Note of even date herewith in the principal
                  face  amount  of  ONE  MILLION  DOLLARS  ($1,000,000.00)  (the
                  "Revolving  Note"),  which will be in form and  substance  and
                  payable on the terms  approved by Lender.  It is  specifically
                  agreed that the  aggregate of advances made during the term of
                  the Revolving Note may exceed the face amount thereof, but the
                  unpaid  principal  balance due on the Revolving  Note will not
                  exceed the lesser of (i) the Borrowing  Base; or (ii) the face
                  amount of the Revolving Note.

                                      -2-
<PAGE>

            2.3.2 Advances. Advances under the Revolving Note will be limited to
                  the Borrowing  Base. The Borrowing Base shall be determined on
                  a  monthly  basis  upon the  submission  of a signed  "Monthly
                  Borrowing Base  Certificate" in form acceptable to the Lender.
                  Each Monthly Borrowing Base Certificate will be supported by a
                  current   accounts    receivable   aging,   and   such   other
                  documentation  that may  reasonably  required by the Lender to
                  determine  the  Borrowing  Base.  After  determination  of the
                  Borrowing  Base  for any  given  month,  Borrower  may  obtain
                  advances by submitting an "Advance Request" in form acceptable
                  to the Lender.

            2.3.3 Maturity.  Notwithstanding anything herein to the contrary the
                  Revolving Note will mature and become fully due and payable on
                  April 15, 2004.

      2.4   Interest.  Interest  on each of Term  Note I,  Term  Note II and the
            Revolving  Note will be paid at the interest rate equal to the Prime
            Rate plus two percent (2 %) per annum, adjusted on each day on which
            a change in the Prime Rate  occurs  (the  "Interest  Rate").  "Prime
            Rate" means the prime rate as published in the "Money Rates Section"
            of the Wall Street Journal, which rate is not necessarily the lowest
            rate of  interest  charged by the Lender.  All  interest on the Term
            Note will be  calculated  for the actual number of days elapsed at a
            per diem charge based on a year consisting of 360 days.

      2.5   Notation of Advances. The Lender shall have the right (acting at its
            sole  discretion  with or without the consent of the Borrower)  from
            time make  notations  of advances by it to the Borrower and payments
            to it by the Borrower on any liability ledger records  maintained by
            or for the Lender as to  indebtedness  of Borrower,  and such ledger
            shall be  presumed  correct  until the  contrary is  established  by
            Borrower.  Upon  demand  by the  Lender  at any time or from time to
            time,  the  Borrower  will  confirm and admit by signed  writing the
            exact  amount  of  indebtedness  for  principal  and  interest  then
            outstanding   under  this  Agreement.   Any  billing   statement  or
            accounting  rendered by or for the Lender  shall be  conclusive  and
            fully  binding  on  Borrower  unless  specific   written  notice  of
            exception is given to the Lender by Borrower within thirty (30) days
            thereafter.

      2.6   Authority  to  Request  Advances.  The  Lender may make loans in any
            amount  and in any  manner  requested  orally or in  writing  by any
            officer  or  agent  of  the  Borrower  or by any  person  reasonably
            believed  by the Lender to be an  officer or agent of the  Borrower.
            Loan proceeds may be disbursed by deposit in any deposit  account of
            the Borrower, by an instrument payable to Borrower.

      2.7   Prepayment. The Borrower may prepay Term Note I, Term Note II or the
            Revolving  Note  at any  time,  without  premium  or  penalty.  Each
            prepayment  will be applied by the  Lender  first to the  payment of
            unpaid fees and expenses,  then to accrued interest on the Revolving
            Note  and  then to the  payment  of  principal.  If at any  time the
            aggregate  outstanding  principal  balance  of the  debt  under  the
            Revolving  Note exceeds the then amount of the Borrowing  Base,  the
            Borrower shall  immediately,  without  notice or demand,  prepay the
            Revolving Note in an amount equal to the excess.

                                      -3-

      2.8   Use of  Proceeds.  The  Borrower  will use the proceeds of all loans
            under this  Agreement  solely for  lawful and  authorized  corporate
            purposes in furtherance of the business  presently  conducted by the
            Borrower.

      2.9   Lending  Restrictions.  Notwithstanding  any other provision of this
            Agreement or the other Loan  Documents,  any advance herein provided
            for  will not be  required  to be made by the  Lender:  (a) if after
            making such  advance,  the Lender  would,  as determined in the sole
            discretion of the Lender,  exercised in good faith,  be in violation
            of any regulatory  requirements  imposed by any branch of government
            of the United  States of America  or any state  thereof;  (b) if any
            event of Default has occurred and has not been cured by the Borrower
            or waived by the Lender;  (c) if,  since the Closing  Date and up to
            the date of the advance  request,  any  litigation  or  governmental
            proceeding has been instituted  against the Borrower,  the Guarantor
            or any of the Collateral,  which, if decided adversely, will, in the
            reasonable  opinion of the  Lender,  adversely  affect to a material
            extent,  the  financial  condition  or  continued  operation  of the
            Borrower;  or (d) if,  since the Closing  Date and up to the date of
            the  advance  request,  any  loss,  destruction,  liens,  claims  or
            encumbrances  against  any of the  Collateral  (other  than those in
            favor of the Lender) have occurred,  been made or filed and have not
            been removed or settled to the satisfaction of the Lender.

            Term Note I, term  Note II and the  Revolving  Note and Term Note I,

            conducted by each of them and representing amounts then invoiced and

                  notification  repudiating  such  obligation or asserting  that

                  stated in the  invoice,  not more than  thirty  (30) days have

                  debtor is not satisfactory to the Lender for any reason; and

            4.1.6 The account  debtor is not an entity in which the  Borrower or

                  (90)  days  is  attributable  to an  isolated  dispute  over a
                  specific invoice.

            the Revolving Note and then to principal balance.

            notice to such  effect  shall  have been  given by the Lender to the
            Borrower or the Guarantors; or any such plan shall be terminated, or

11.   REMEDIES.  On the  occurrence  of an event of  Default  which has not been
      timely  cured,  the Lender may terminate  all  Indebtedness  of the Lender
      under the Loan Documents, including, without limitation, any obligation to
      make advances under the Revolver,  and may exercise any one or more of the
      following options:

      11.1  Termination  of Lender  Obligations.  The Lender may  terminate  the
            obligations of the Lender under this Agreement.

      11.2  Acceleration.  The Lender may declare the Indebtedness  evidenced to
            be  immediately  due and  payable,  and the same shall  thereupon be
            immediately due and payable,  without notice or presentment or other
            demand, and the Lender thereupon may exercise and enforce all rights
            and remedies available to it to collect the Indebtedness;

      11.3  Selective Enforcement. In the event the Lender elects to selectively
            and  successively  enforce the Lender's rights under any one or more
            of the instruments securing payment of the Indebtedness, such action
            will not be  deemed a  waiver  or  discharge  of any  other  lien or
            encumbrance  securing payment of the Indebtedness until such time as
            the Lender has been paid in full all sums advanced by the Lender;

      11.4  Waiver of Event of  Default.  The Lender may,  by an  instrument  in
            writing  signed by the Lender,  waive any event of Default  that has
            occurred and any of the  consequences of such event of Default;  and
            in such event,  the Lender,  the Borrower and the Guarantors will be
            restored  to  their   respective   former   positions,   rights  and
            Indebtedness  under  the Loan  Documents.  Any event of  Default  so
            waived will, for all purposes of this  Agreement,  be deemed to have
            been cured and not to be continuing,  but no such waiver will extend
            to  any   subsequent  or  other  event  of  Default  or  impair  any
            consequence of such subsequent or other event of Default. The rights
            and remedies of the Lender shall be  cumulative  and the exercise or
            enforcement  of any one right or remedy shall neither be a condition
            to nor bar the exercise and enforcement of any other;

      11.5  Performance  by Lender.  In the event the Borrower or the Guarantors
            fail to cure any Default in the time  provided  by the  Lender,  the
            Lender  will at any  time  thereafter  have the  right  (but not the
            obligation)  to pay any claim or lien (whether  prior or subordinate
            to liens held by the Lender)  affecting the  Collateral  and to take
            possession   of  the   Collateral  in  such  manner  as  the  Lender
            determines.  The Borrower and the  Guarantors  hereby  authorize the
            Lender to increase  the  indebtedness  owing by the  Borrower to the
            Lender by the cost of satisfying  claims  against the Collateral and
            the cost of  repossession of the Collateral and agrees that the Loan
            Documents  will evidence and secure payment of such costs whether or
            not the total  funds  advanced  exceed  the face  amount of the Loan
            Documents;

      11.6  Cumulative  Remedies.  No  failure  on the  part  of the  Lender  to
            exercise and no delay in exercising any right hereunder will operate
            as a waiver thereof,  nor will any single or partial exercise by the

                                      -17-

<PAGE>

            Lender of any right hereunder preclude any other or further right of
            exercise  thereof or the exercise of any other  right.  The remedies
            herein provided are cumulative and not alternative; and

      11.7  Setoff.  Regardless of the adequacy of any other  Collateral held by
            the Lender,  any deposits or other sums  credited by or due from the
            Lender to the  Borrower or any of the  Guarantors  will at all times
            constitute  collateral  security for all of the  Indebtedness of the
            Borrower and the  Guarantors  and may be set off against any and all
            liabilities,  direct or indirect,  absolute or contingent, due or to
            become due, now existing or  hereafter  arising,  of the Borrower or
            the  Guarantors to the Lender.  The rights granted by this paragraph
            will be in addition to the rights of the Lender under any  statutory
            lien.

12.   RELEASE.  Borrower and Guarantors  hereby  jointly and severally  release,
      acquit and forever  discharge  the Lender and the  Lender's  subsidiaries,
      affiliates,   officers,   directors,   shareholders,   agents,  employees,
      servants, attorneys and representatives,  as well as the respective heirs,
      personal  representatives,  successors  and assigns of any and all of them
      (hereafter collectively called the "Released Lender Parties") from any and
      all claims,  demands,  debts, actions, causes of action, suits, contracts,
      agreements,  obligations, accounts, defenses, offsets against indebtedness
      and  liabilities  of any kind or character  whatsoever,  known or unknown,
      suspected  or  unsuspected,  in contract or in tort,  at law or in equity,
      including without implied  limitation,  such claims and defenses as fraud,
      mistake,  duress and usury,  which the Borrower or Guarantor ever had, now
      have, or might hereafter have against the Released Lender Parties, jointly
      or severally,  for or by reason of any matter,  cause or thing  whatsoever
      occurring prior to the date of this  Agreement,  whether or not related in
      whole or in part,  directly or indirectly to the Borrower's or Guarantor's
      indebtedness.  In  addition,  the  Borrower  and  Guarantor  agree  not to
      commence,  join  in,  prosecute  or  participate  in  any  suit  or  other
      proceeding  in a position  which is adverse to any of the Released  Lender
      Parties arising directly or indirectly from any of the foregoing matters.

13.   MISCELLANEOUS. It is further agreed as follows:

      13.1  Recitals.  The recitals are hereby acknowledged by the parties to be
            true and correct and are adopted and incorporated herein as material
            terms of this Agreement.

      13.2  Fees.   In  partial   consideration   of  the  extension  of  credit
            contemplated  under this  Agreement,  the Borrower  shall pay to the
            Lender  origination  fees in the  amount  of  1.5%  of the  original
            principal  balances of Term Note I and the Revolving Note and of .5%
            of the  original  principal  balance of Term Note II.  The  Borrower
            shall  also pay a fee of  $5,000  in  partial  consideration  of the
            Lender's  waiver of financial  covenant  defaults in connection with
            the Prior  Loan  Documents  and of the  Lender's  consent  to future
            distributions.

                                      -18-

<PAGE>

      13.3  Hold  Harmless.  The  Borrower  and the  Guarantors  hereby agree to
            indemnify  and hold the Lender  harmless from all  liability,  loss,
            damage or expense,  including  reasonable  attorney's fees,  whether
            incurred under  retainer,  salary or otherwise,  that the Lender may
            incur in good faith in  compliance  with or the  enforcement  of the
            terms of this Agreement or any of the Loan Documents.

      13.4  Expenses.  The Borrower will pay all reasonable  expenses (including
            legal expenses and attorney's fees) of every kind resulting from any
            future modification or enforcement of the Loan Documents.

      13.5  Supersession.  It is agreed and understood between the Borrower, the
            Guarantors  and the Lender that:  (a) except to the extent the Prior
            Loans Documents are amended  hereby,  the Prior Loans will remain in
            full force and effect;  (b) the Borrower and Guarantor hereby adopt,
            confirm  and  reaffirm  each  and  every  promise,   representation,
            warranty and covenant set forth in each of the Prior Loan  Documents
            as fully as if each of such matters  were  restated and set forth in
            this  Agreement;  and (c) the execution of this  Agreement  will not
            discharge, interrupt, impair, abate or otherwise modify the priority
            or the validity of any lien or security interest securing payment of
            the indebtedness evidenced by the Prior Loan Documents.

      13.6  Notices.  All notices,  requests and demands will be served by first
            class or express mail, postage prepaid, or sent by telex,  telegram,

            a written  notice to the other  parties.  Notices  will be deemed to
            have been given on the date notice is sent by rapid  transmission or
            three  business  days after  notice is placed in the mail,  properly
            addressed, postage prepaid.

      13.7  Construction.  Nothing contained in this Agreement will be construed
            to  constitute  the Lender as a joint  venturer with the Borrower or
            the  Guarantors  or to  constitute a  partnership.  The  descriptive
            headings of the  paragraphs of this  Agreement  are for  convenience
            only and are not to be used in the  construction  of the  content of
            this   Agreement.   This  Agreement  may  be  executed  in  multiple
            counterparts,  each of which will be an original instrument, but all
            of which will constitute one agreement.

      13.8  Venue.  This  Agreement  and  the  documents  issued  hereunder  are
            executed  and  delivered  as an  incident  to a lending  transaction
            negotiated and to be performed in Tulsa, Tulsa County, Oklahoma. The
            Loan  Documents are intended to constitute a contract made under the
            laws of the State of Oklahoma and to be construed in accordance with
            the internal laws of said state.  The Borrower,  the  Guarantors and
            the  Lender  hereby  waive  all   objections   and  consent  to  the
            jurisdiction  and venue of any state or  federal  court  sitting  in
            Tulsa County, Oklahoma.

<PAGE>

      13.9  Severability. In case any one or more of the provisions contained in
            the Loan Documents  should be invalid,  illegal or  unenforceable in
            any  respect  in  any  jurisdiction,   the  validity,  legality  and
            enforceability  of such provision or provisions  will not in any way
            be affected or impaired thereby in any other  jurisdiction;  and the
            validity,  legality and  enforceability of the remaining  provisions
            contained  herein and  therein  will not in any way be  affected  or
            impaired thereby.

      13.10 No Oral  Modification.  This Agreement may not be amended,  altered,
            modified or changed  verbally,  but only by an  agreement in writing
            signed by the  party  against  whom  enforcement  of any  amendment,
            waiver, change, modification or discharge is sought.

      13.11 Extension of Loan Term. It is understood that the Lender is under no
            obligation to extend the term of this Agreement  beyond the maturity
            of any of the notes and that any such  extension will be made at the
            Lender's sole  discretion.  Any such  extension will be evidenced by
            the  acceptance  by the Lender of a  promissory  note  renewing  and
            extending  the  time  of  payment  of  any  of the  notes  on  terms
            acceptable to the Lender.

                                      -20-

<PAGE>

      13.12 No  Waiver.  No  advance  of loan  proceeds  under  any of the  Loan
            Documents  will  constitute a waiver of any of the  representations,
            warranties,   conditions   or  covenants  of  the  Borrower  or  the
            Guarantors  under the Loan  Documents.  In the event the Borrower or
            the  Guarantors  are unable to satisfy any  warranty,  condition  or
            covenant  contained  in the  Loan  Documents,  no  advance  of  loan
            proceeds will  preclude the Lender from  thereafter  declaring  such
            inability to be an event of Default.

      13.13 Exclusive Benefit.  All provisions of the Loan Documents are for the
            sole and  exclusive  benefit of the  Lender,  the  Borrower  and the
            Guarantors  and no  other  person  will  have  standing  to  require
            satisfaction of the provisions thereof or be entitled to assume that
            advances thereunder will not be made by the Lender in the absence of
            strict compliance with the provisions of the Loan Documents. Any and
            all  provisions of the Loan Documents may be waived by the Lender in
            whole  or in part at any  time if,  in the  sole  discretion  of the
            Lender, it is advisable to do so.

      13.14 Application of Loan Proceeds. The Lender may apply the loan proceeds
            under  Term  Note  I,  Term  Note  II or the  Revolving  Note to the
            satisfaction of any condition,  warranty or covenant of the Borrower
            under any of the Loan Documents, and any proceeds so applied will be
            considered as a part of the loan proceeds  advanced  under Term Note
            I, Term Note II or the  Revolving  Note will be  secured by the Loan
            Documents.

      13.15 Binding Effect. This Agreement will be binding on the Borrower,  the
            Guarantors and their successors and permitted assigns and will inure
            to the  benefit  of the  Lender  and  the  Lender's  successors  and
            assigns.

      13.16 Counterparts.   This   Agreement   may  be   executed   in  multiple
            counterparts,  each of which will be an original instrument, but all
            of which will constitute one agreement.

     IN WITNESS WHEREOF,  the Borrower,  the Guarantors and the Lender have duly
executed this Agreement effective the date first above written.

Flemming  and  Stuart  are  currently  indebted  to the Lender by virtue of that
certain Amended and Restated Loan Agreement  effective as of April 30, 2003 (the
"Existing Debt");

      WHEREAS, the Existing Debt and agreements thereto are evidenced by various
loan agreements,  promissory notes,  security  agreements,  guaranties and other
instruments and agreements (collectively, the "Existing Loan Documents");

      WHREREAS,  additional  borrowing  is needed for working  capital and other
expenses;

      NOW,  THEREFORE,  in  consideration of the mutual  agreements  between the
parties and the funds to be advanced to the Borrower, it is agreed as follows:

1.    LENDING  AGREEMENT.  Subject to the terms and conditions  hereinafter  set
      forth,  Lender  agrees to lend to  Industries  and Shumate the amounts set
      forth below.

2.    TERM NOTE.  Industries will execute and deliver to the Lender a Promissory
      Note of even date  herewith in the  principal  face amount of FIVE HUNDRED
      FIFTY THOUSAND DOLLARS  ($550,000.00) (the "Industries Note"),  which will
      be in form and substance and payable on the terms approved by Lender.  The
      Industries Note shall mature and become due on December 15, 2003, at which
      time,  the  Borrower  will pay the entire  outstanding  principal  balance
      together with all accrued interest and other charges, if any.

3.    SHUMATE  REVOLVER.  The Lender  will  provide  Shumate  and  Industries  a
      revolving line of credit as follows:

      3.1   Note.  Promissory  Note of even date herewith in the principal  face
            amount of FIVE HUNDRED FIFTY  THOUSAND  DOLLARS  ($550,000.00)  (the
            "Shumate Note"),  which will be in form and substance and payable on
            the terms  approved by Lender.  It is  specifically  agreed that the
            aggregate  of advances  made during the term of the Shumate Note may
            exceed the face amount thereof, but the unpaid principal balance due

                                      -1-
<PAGE>

            on the Shumate Note will not exceed the lesser of (i) the  Borrowing
            Base; or (ii) the face amount of the Shumate Note.

      3.2   Advances.  Advances  under the  Shumate  Note will be limited to the
            Borrowing  Base.  The  Borrowing  Base  shall  be  determined  twice
            monthly,  on the  15th  day of each  month  and the last day of each
            month,   on  submission  of  a  signed   "Monthly   Borrowing   Base
            Certificate"  in the same  form as  provided  by the  Existing  Loan
            Documents. Each Monthly Borrowing Base Certificate will be supported
            by a current accounts receivable aging, and such other documentation
            that  may  reasonably  required  by  the  Lender  to  determine  the
            Borrowing Base.  After  determination  of the Borrowing Base for any
            given month,  Borrower may obtain advances by submitting an "Advance
            Request" in the form required by the Existing Loan Documents.

      3.3   Maturity.  Notwithstanding  anything  herein  to  the  contrary  the
            Shumate Note will mature and become fully due and payable on October
            28, 2004.

4.    INTEREST. Interest on the Industries Note and the Shumate Revolver will be
      paid at the  interest  rate equal to the Prime Rate plus two percent (2 %)
      per annum, adjusted on each day on which a change in the Prime Rate occurs
      (the "Interest  Rate").  "Prime Rate" means the prime rate as published in
      the "Money Rates  Section" of the Wall Street  Journal,  which rate is not
      necessarily  the  lowest  rate of  interest  charged  by the  Lender.  All
      interest on the Term Note will be calculated for the actual number of days
      elapsed at a per diem charge based on a year consisting of 360 days.

5.    RECOURSE.  The indebtedness  will be full recourse to the Borrower and the
      Guarantors.

6.    BORROWING  BASE.  "Borrowing  Base"  means,  as of any given date,  eighty

      Receivable of Shumate subject to the following:

      6.1   "Trade  Accounts  Receivable"  means,  as of  any  given  date,  all
            accounts  receivable  of Shumate  (which shall be excluded  from the
            Borrowing Base under the Existing Loan Documents) for goods sold and
            delivered and services rendered by Shumate in the ordinary course of
            the business  presently  conducted by Shumate  representing  amounts
            then invoiced and due and owing. A Trade Account Receivable shall be
            an "Eligible Trade Account Receivable", and shall be included in the
            Borrowing  Base, only if and so long as it meets each and all of the
            following requirements:

            6.1.1 It is a valid,  genuine  and legally  enforceable  obligation,
                  subject  to no  defense,  set  off  or  counter-claim,  of the
                  account debtor or other obligor named herein or in the records
                  of Shumate pertaining  thereto,  and that Shumate has received
                  from the  account  debtor or other  obligor  any  notification
                  repudiating  such obligation or asserting that such obligation
                  is subject to any defense, set off or counterclaim; and

                                      -2-
<PAGE>

            6.1.2 It is owned by Shumate free and clear of all interests, liens,
                  attachments,  encumbrances  and security  interests except the
                  security interests granted to the Lender; and

            6.1.3 The Account  debtor or other  obligor is located in the United
                  States; and

            6.1.4 Not more than ninety (90) days have expired  since the date of
                  invoice;  or, if the Lender in its sole discretion  accepts as
                  eligible  a Trade  Account  Receivable  which is due on a date
                  stated in the  invoice,  not more than  thirty  (30) days have
                  expired since the date stated; and

            6.1.5 Shumate  has not  received  notice  from the  Lender  that the
                  credit of the account debtor is not satisfactory to the Lender
                  for any reason; and

            6.1.6 The account debtor is not an entity in which Shumate or any of
                  the guarantors has a controlling interest; and

            6.1.7 Eligible  Trade  Accounts  Receivable  shall not  include  any
                  account  receivable  of the same account  debtor to Shumate in
                  excess of fifteen  percent  (15%) of the then  Eligible  Trade
                  Accounts Receivable calculated after ineligible accounts; and

            6.1.8 The entire receivable of one account debtor becomes ineligible
                  if more than ten percent (10%) of the total due is over ninety
                  (90) days past due,  unless the ten percent  (10%) over ninety
                  (90)  days  is  attributable  to an  isolated  dispute  over a
                  specific invoice.

      6.2   The value of Inventory used in determining  the Borrowing Base shall
            equal the value of raw material  plus the value of finished  product
            and shall not include the value of any work in progress.
