2.1     Revolving Credit Loans.

        (a)     Drawdowns.  The Bank  agrees,  on the terms and  conditions  set
                forth  herein  and upon at least  two (2)  Banking  Days'  prior
                notice from UPET,  to make  Revolving  Credit Loans  jointly and
                severally  available  to Borrowers  in the  aggregate  principal
                amount not at any time  exceeding  the  lesser of the  Borrowing
                Base, as determined in subsection  (c) below,  or  US$4,233,000.
                The notice from UPET shall specify whether the Revolving  Credit
                Loan is to be a Prime  Rate Loan or a LIBOR  Loan,  the  Drawing
                Date of the Loan and the  account at the Bank of a  Borrower  to
                which  the  Loan  is to be  credited  and  shall  include  or be
                accompanied   by  a   certificate   setting  forth  the  current
                calculation of the Borrowing Base.

        (b)     Repayment.  Borrowers  shall have the right to repay in whole or
                in part without  penalty or premium Prime Rate Revolving  Credit
                Loans at any  time and  LIBOR  Revolving  Credit  Loans on LIBOR
                Determination  Dates for the LIBOR Revolving  Credit Loans being
                repaid.  Any such  repayments of a LIBOR  Revolving  Credit Loan
                also shall be upon at least two (2) Banking Days prior notice to
                the Bank.  Borrowers  shall have the right prior to the Maturity
                Date, or one (1) month prior to the Maturity Date in the case of
                a LIBOR  Revolving  Credit Loan, to reborrow as provided in this
                Section 2.1,  provided,  that, all outstanding  Revolving Credit
                Loans shall be due and  payable  jointly  and  severally  by the
                Borrowers on the  Maturity  Date.  If at any time the  aggregate
                principal amount of outstanding  Revolving Credit Loans shall be
                greater than the Borrowing  Base,  Borrowers  immediately  shall
                repay Revolving  Credit Loans in an amount  sufficient to reduce
                the aggregate  principal amount of outstanding  Revolving Credit
                Loans  to less  than the  Borrowing  Base.  Repayments  shall be
                accompanied by payment of accrued  interest on the amount repaid
                to the date of repayment  and, in the case of any repayment of a
                LIBOR  Revolving  Credit  Loan on a date  other  than its  LIBOR
                Determination Date, any amount required by Section 4.4 hereof.

        (c)     Borrowing Base. Until the first anniversary of the Closing Date,
                the Borrowing  Base for  Revolving  Credit Loans shall be at any
                time an  amount  equal  to the sum of  eighty  percent  (80%) of
                Borrowers'  eligible  accounts  receivable  plus eighty  percent
                (80%) of Borrowers' eligible inventory. Thereafter the Borrowing
                Base for  Revolving  Credit Loans shall be at any time an amount
                equal to the sum of eighty percent (80%) of Borrowers'  eligible
                accounts  receivable  plus seventy  percent  (70%) of Borrowers'
                eligible inventory. Eligible accounts receivable are non-related
                accounts of any borrower (i.e.,  accounts due from parties not a
                Borrower or affiliated  with any Borrower),  for which there are
                no contra accounts,  that are outstanding for up to 60 days from
                due date and otherwise  complying with the  representations  and
                warranties  and  other  terms  and  conditions  of the  Security
                Agreements.  Any account  with more than 50% of its balance past
                due more than 60 days will be deemed ineligible in its entirety.
                Eligible  inventory is inventory of any Borrower  complying with
                the   representations   and   warranties  and  other  terms  and
                conditions of the Security Agreements and excludes the amount of
                any reserve, for obsolescence or otherwise,  placed against such
                inventory on the financial  statements  of  Borrowers.  The Bank
                retains the right from time to time to  establish  standards  of
                eligibility  and reserves  against  availability in its sole but
                reasonable discretion.

2.2     Mortgage  Loan.  The Bank agrees,  on the terms and conditions set forth
        herein,  to make the Mortgage Loan to Borrowers in the principal  amount
        of  US$8,300,000  on the  Closing  Date.  The  Mortgage  Loan  shall  be
        repayable  jointly and severally by Borrowers in monthly level principal
        and  interest  payments  based  upon a fifteen  (15)  year  amortization
        schedule  (readjusted  upon any change in interest  rate to reflect such
        change in interest  rate) and a balloon  payment on the Maturity Date of
        all amounts then  outstanding  under the Mortgage Loan.  Notwithstanding
        the  foregoing,  in no event shall the principal  amount of the Mortgage
        Loan exceed eighty  percent  (80%) of the  appraised  value of the Owned
        Real Properties as set forth in the appraisals described in Article IX.

2.3     Term  Loan.  The Bank  agrees,  on the  terms and  conditions  set forth
        herein,  to make the Term Loan to Borrowers in the  principal  amount of
        US$10,467,000  on the  Closing  Date.  The Term Loan shall be  repayable
        jointly and severally by Borrowers  beginning thirteen (13) months after
        the Closing Date in equal monthly  principal  payments  based upon a six
        (6) year  amortization  schedule  and a balloon  payment on the Maturity
        Date  of  all   amounts   then   outstanding   under   the  Term   Loan.
        Notwithstanding  the foregoing or any other  conflicting or inconsistent
        provision herein, if the original  principal amount of the Mortgage Loan
        is less than  US$8,300,000,  the original  principal  amount of the Term
        Loan, at the option of UPET, may be increased by up to US$750,000 of the
        amount of such reduction in the Mortgage Loan, provided,  however,  that
        the aggregate  principal  amounts of the Mortgage Loan and the Term Loan
        shall not exceed US$18,767,000.

2.4     Interest.  Borrowers  jointly and  severally  shall pay  interest on the
        unpaid principal amount of the Loans from the date made available by the
        Bank to a Borrower until maturity as follows:

        (a)     Revolving Credit Loans shall bear interest at the option of UPET
                at rates per annum  equal to (i) the sum of Prime  Rate plus one
                percent  (1.0%)  or (ii)  the  sum of  three  and  seven-eighths
                percent  (3.875%) plus LIBOR. Any change in the Prime Rate shall
                take effect  immediately  with respect to interest on Prime Rate
                Revolving Credit Loans. Any Prime Rate Revolving Credit Loan may
                be  converted  into a LIBOR  Revolving  Credit Loan upon two (2)
                Banking  Days  prior  notice  by UPET  to the  Bank.  Any  LIBOR
                Revolving   Credit   Loan  may  be   converted   on  any   LIBOR
                Determination  Date for such LIBOR Revolving  Credit Loan into a
                Prime Rate Revolving Credit Loan upon two (2) Banking Days prior
                notice by UPET to the Bank.

        (b)     The Mortgage  Loan shall bear  interest at the option of UPET at
                rates per annum  equal to (i) the sum of Prime Rate plus one and
                one-eighths  percent  (1.125%)  or (ii) the sum of four  percent
                (4.0%) plus LIBOR.  At least two (2) Banking  Days prior to each
                six (6) month anniversary of the Closing Date, UPET shall advise
                the Bank whether the interest  rate on the Mortgage Loan for the
                following six (6) month period shall be computed with  reference
                to the Prime  Rate in effect on the first day of such  following
                six (6) month period or LIBOR for such  following  six (6) month
                period. If the Prime Rate option is selected,  the interest rate
                for the  entire  six (6) month  period  shall be based  upon the
                Prime  Rate in  effect  on the  first  day of the six (6)  month
                period.

        (c)     The Term Loan shall bear  interest  at a rate per annum equal to
                the sum of Prime Rate plus three percent  (3.0%).  Any change in
                the Prime Rate shall take effect immediately.

        (d)     All interest shall be computed on the basis of the actual number
                of days  elapsed in a 360 day year and shall be payable  monthly
                in arrears and on payment in full of the Loans.  Borrowers agree
                that any amount of  principal  of any of the  Loans,  and to the
                extent  permitted by law  interest,  that is not paid on its due
                date (whether at stated maturity,  by acceleration or otherwise)
                shall bear  interest  from such due date until paid in full at a
                rate per annum equal to the rate provided in (a) - (c) above, as
                the case may be, plus five percent  (5.0%),  provided  that such
                interest  rate  shall not at any time  exceed the  maximum  rate
                allowed by law. Default interest shall be payable on demand.

2.5     Prepayment of the Mortgage Loan and the Term Loan.

        (a)     Mandatory Prepayments.

                (i) The net cash proceeds  from the sale of any non-real  estate
                assets (other than (1) sales of inventory in the ordinary course
                of business,  (2) sales of assets to the extent the proceeds are
                applied  to the  repair or  replacement  of  Collateral  and (3)
                immaterial  sales not exceeding  US$50,000 in any fiscal year of
                Borrowers)  of any of the  Borrowers  shall be used to repay the
                Term Loan.  Any remaining  excess  proceeds from the sale of any
                non-real  estate  assets after payment in full of the Term Loan,
                shall  be  applied  first to the  Mortgage  Loan and then to the
                Revolving  Credit  Facility.  Prepayments  under this subsection
                shall  be due  within  ten  (10)  days of  receipt  of any  cash
                proceeds.

                (ii) The net  cash  proceeds  from  the sale of any real  estate
                assets  of any of the  Borrowers  shall  be  used to  repay  the
                Mortgage Loan. Any remaining excess proceeds for the sale of any
                real estate,  after  application to the Mortgage Loan,  shall be
                applied  first to the Term  Loan and then the  Revolving  Credit
                Facility.  Prepayments under this subsection shall be due within
                ten (10) days of receipt of any cash proceeds.

                (iii) Fifty percent  (50%) of the cash proceeds  received by any
                Borrower  from the issuance of debt  securities by any Borrower,
                net of all costs and  expenses  associated  with the issuance of
                such  debt  securities,  shall  be  used  to  reduce  Borrowers'
                obligations first under the Term Loan, second under the Mortgage
                Loan and third under the Revolving Credit Facility.  Prepayments
                under  this  subsection  shall  be due  within  five (5) days of
                receipt of any cash proceeds.

                (iv) Twenty-five  percent (25%) of the cash proceeds received by
                any  Borrower  from the  issuance  of equity  securities  by any
                Borrower  net of all  costs  and  expenses  associated  with the
                issuance  of such  equity  securities,  shall be used to  reduce
                Borrowers'  obligations  first under the Term Loan, second under
                the Mortgage Loan and third under the Revolving Credit Facility.
                Prepayments  under this subsection  shall be due within five (5)
                days of receipt of any cash proceeds.

                (v) The  Term  Loan  shall  be  prepaid  by an  amount  equal to
                twenty-five percent (25%) of UPET's consolidated net income plus
                depreciation and  amortization  (during the period under review)
                minus principal payments made and net cash capital  expenditures
                (during the period under  review),  all  computed in  accordance
                with GAAP. The  calculations  and prepayments  shall be effected
                for the six  months  prior  to each  fiscal  year  and for  each
                intervening six month period and for any "short" fiscal year due
                to a change  in  UPET's  fiscal  year,  provided  that the first
                period to which this  subsection is applicable  shall be the six
                month  period  ending  June 30,  2000 or the end of the  "short"
                fiscal year if a change in UPET's  fiscal  year occurs  prior to
                June 30, 2000.  Prepayments  under this subsection  shall be due
                within ninety (90) days of the end of a fiscal year for a period
                under review  ending on a fiscal year end and within  forty-five
                (45) days of the end of any intervening period under review.

                (vi) Any partial prepayments shall be applied to installments of
                principal  due in the  inverse  order  of  their  maturity.  Any
                mandatory  prepayment  of a LIBOR  Loan on a date other than its
                LIBOR  Determination Date may, at the Bank's sole option, (A) be
                held as cash  collateral  until  such  LIBOR  Loan's  next LIBOR
                Determination  Date and  applied as a  prepayment  on such LIBOR
                Determination Date or (B) be applied  immediately by the Bank as
                a prepayment,  but without Borrowers incurring any liability for
                any  indemnity  payment  of any  amount  otherwise  required  by
                Section 4.4 hereof.

        (b)     Voluntary  Prepayments.  Borrowers  shall have the right, on any
                Banking  Day,  to prepay the  Mortgage  Loan or the Term Loan or
                both in whole  or in part,  provided  that any  prepayment  of a
                LIBOR Loan on a day other than a LIBOR  Determination  Date with
                respect  thereto  shall be  subject  to  payment  of any  amount
                required by Section 4.4 hereof. Any partial prepayments shall be
                in the amount of US$100,000 or an integral  multiple thereof and
                shall be applied to installments of principal due in the inverse
                order of their maturity.

        (c)     Exit Fee. Any  prepayment  shall be accompanied by prepayment of
                accrued interest on the amount prepaid.  Subsequent to 18 months
                from  the  Closing  Date,  an Exit  Fee  shall  be  payable  for
                prepayments of the Mortgage Loan or the Term Loan or both, other
                than pursuant to Subsection 2.5(a) (v), in amounts equal to

                (i)  the  amount  prepaid  divided  by (A) the  total  principal
                amounts of the Mortgage  Loan and the Term Loan  outstanding  18
                months   after  the   Closing   Date  less  (B)  the   principal
                amortization  amounts  scheduled to be paid from 18 months after
                the Closing Date to the Maturity Date

                multiplied by

                (ii) US$350,000,

                provided,  however,  that if prepayments of the Mortgage Loan or
                the Term Loan or both have  occurred  within 18 months  from the
                Closing  Date,  the  US$350,000  amount set forth above shall be
                reduced by the percentage that such prepayments within 18 months
                of the Closing Date bear to the total original principal amounts
                of the Mortgage Loan and the Term Loan.

2.6     Payments.  All  payments  hereunder  shall  be made  without  setoff  or
        counterclaim   and  shall  be  made  through  demand  deposit   accounts
        maintained  by each  Borrower at the Bank's Main Office,  3750 N.W. 87th
        Avenue, Miami, Florida 33178, U.S.A., (or at such other branch or office
        of the Bank as the  Bank may from  time to time  specify  by  notice  to
        UPET).

2.7     Withholding and Taxes.

        (a)     All amounts  payable  under this  Agreement  or under any of the
                other  Documents  shall be made without  set-off or counterclaim
                and clear of and without  deduction  for any and all present and
                future   taxes,   levies,    imposts,    deductions,    charges,
                withholdings,   contributions,  services,  surcharges,  exchange
                commissions,  penalties and all liabilities with respect thereto
                imposed by any  governmental  or taxing  authority  (other  than
                income or  franchise  taxes  based on or measured by the overall
                net income or capital of the Bank  imposed by the United  States
                of  America  or the State of  Florida),  including  any stamp or
                other taxes, registration fees or other duties, levies, imposts,
                notarial  fees or other  charges  of any  nature  whatsoever  by
                whomsoever  imposed with respect to the preparation,  execution,
                delivery,  registration,  performance  and  enforcement  of this
                Agreement  and  any  of  the  other   Documents   (collectively,
                "Taxes").  Borrowers  agree  to  cause  all  Taxes to be paid on
                behalf  of the Bank  directly  to the  appropriate  Governmental
                Authority.  If for any  reason  Borrowers  are  prohibited  from
                paying any Taxes on behalf of the Bank,  then all payments  made
                on or in  respect  of this  Agreement  including  payments  made
                pursuant to this  Section,  shall be  increased  so that,  after
                provisions for such Taxes, including Taxes on such increase, the
                amounts  received  by the Bank will equal the  amounts  the Bank
                would have  received if no Taxes were due on such  payments.  If
                any of the amounts referred to in this Section are paid by or on
                behalf of the Bank, the Bank shall promptly so notify  Borrowers
                and Borrowers shall,  upon demand,  promptly  indemnify the Bank
                for such  payments,  together with any  interest,  penalties and
                expenses in connection  therewith,  plus interest thereon at the
                rate specified in Section 2.4(c) hereof.

        (b)     If,  at any time  and for any  reason  there is a change  in the
                basis of taxation of payments in respect of this  Agreement or a
                Loan  (except  for  changes in taxes  based upon or  measured by
                income or capital of the Bank or the Bank's franchise taxes) and
                the  result  thereof  is to  increase  the  cost to the  Bank of
                maintaining the Loans of to reduce any amount  receivable  under
                this Agreement, then Borrowers shall promptly pay the Bank, upon
                its demand,  any additional  amount  necessary to compensate the
                Bank for such increased cost or reduced amount receivable.

        (c)     Borrower  shall  provide the Bank with  original  tax  receipts,
                notarized copies of tax receipts, or such other documentation as
                will prove  payment of tax in a court of law  applying  the U.S.
                Federal  Rules of  Evidence,  for all  Taxes  paid by  Borrowers
                pursuant to this Section.  Borrower  shall deliver such receipts
                or other  documentation to the Bank within 30 days after the due
                date for the related Tax.

        (d)     The Bank shall upon request  provide  reasonable  assistance  to
                Borrowers  for the purpose of  establishing  any reduction in or
                exemption from deduction or withholding or any liability for any
                Taxes or avoiding or mitigating  such increased costs or reduced
                amounts  receivable,  such assistance in the case of Taxes to be
                limited  to the  timely  provision  of  properly  completed  and
                executed  documentation  sufficient to establish to the relevant
                taxing   authorities   the  entitlement  to  such  reduction  or
                exemption.

        (e)     The  obligations  of Borrowers  under this Section shall survive
                the payment in full or  principal  and interest on the Loans and
                the cancellation of the Notes and any of the other Documents.

                         ARTICLE III: EXPENSES AND FEES

3.1     Structuring  Fees.  Borrower  shall pay to the Bank on the Closing  Date
        Structuring Fees equal to (a) 1.5% flat, or US$63,495,  on the Revolving
        Credit Loan  Commitment,  (b) 1.5% flat, or US$124,500,  on the Mortgage
        Loan Commitment and (c) 7.7577625% flat, or US$812,005, on the Term Loan
        Commitment.  The nonrefundable  US$500,000 fee paid upon delivery of the
        September  27, 1999  commitment  letter for this Loan  Agreement and the
        US$50,000  paid  upon  acceptance  of such  commitment  letter  shall be
        applied  to the total  amount of the  Structuring  Fees.  The Bank shall
        deduct such  balance of the  Structuring  Fees from the  proceeds of the
        Revolving Credit Loans.

3.2     Expenses.  Borrowers  shall  pay to the  Bank all  documentation  costs,
        filing and search fees,  title  insurance  premiums and other  expenses,
        including  reasonable  legal fees of counsel  to the Bank,  incurred  in
        connection with the preparation of the Documents.  The Bank shall deduct
        such amounts from the proceeds of the Revolving Credit Loans.

3.3     Future  Expenses.  Borrowers  shall pay on demand,  whether any Event of
        Default  hereunder  shall have  occurred and  regardless  of whether any
        proceeding  to enforce  the same shall have been  commenced,  the Bank's
        standard  loan fees as set from  time to time by  notice  to the  Bank's
        customers  generally,  all costs and  expenses  of the Bank,  including,
        without  limitation,  all fees and disbursements of counsel to the Bank,
        incurred in connection with the enforcement of the Documents,  including
        any  appeals,  any  waivers or consents  in  connection  herewith or the
        preparation of any amendment to or modification of the Documents.

                   ARTICLE IV: YIELD PROTECTION AND ILLEGALITY

4.1     Inability to  Determine  Interest  Rate.  In the event that prior to the
        first day of any LIBOR Interest Period:

        (a)     the Bank shall have  determined  (which  determination  shall be
                conclusive  and  binding  upon  Borrowers)  that,  by  reason of
                circumstances   affecting  the  relevant  market,  adequate  and
                reasonable  means do not exist for  ascertaining  LIBOR for such
                LIBOR Interest Period, or

        (b)     the Bank  determines that the LIBOR rate for such LIBOR Interest
                Period will not  adequately  and fairly  reflect the cost to the
                Bank (as conclusively  certified by the Bank) of maintaining the
                relevant LIBOR Loan during such LIBOR Interest Period,

        the Bank shall give notice  thereof to UPET as soon as  practicable.  If
        such notice is given, the Loans shall remain or shall be converted to on
        the first day of such LIBOR Interest  Period,  as the case may be, Prime
        Rate Loans.

4.2     Illegality.  Notwithstanding  any other provision  herein, if any change
        after the date hereof in any Requirement of Law or in the interpretation
        or  application  thereof  shall make it unlawful for the Bank to make or
        maintain the LIBOR Loans as contemplated  by this  Agreement,  the LIBOR
        Loans shall be converted  automatically  to Prime Rate Loans on the last
        day of the then  current  LIBOR  Interest  Period or within such earlier
        period as  required by law.  If any such  conversion  of the LIBOR Loans
        occurs on a day  which is not a LIBOR  Determination  Date with  respect
        thereto, Borrowers shall pay to the Bank such amounts, if any, as may be
        required  pursuant to Section 4.4 unless such  illegality was due to the
        fault of the Bank.

4.3     Requirements of Law.

        (a)     In the  event  that any  change  after  the date  hereof  in any
                Requirement  of  Law  or in the  interpretation  or  application
                thereof or  compliance by the Bank with any request or directive
                (whether or not having the force of law) from any  central  bank
                or other  Governmental  Authority  made  subsequent  to the date
                hereof:

                (i)     shall  impose,  modify or hold  applicable  any reserve,
                        special deposit, compulsory loans or similar requirement
                        against assets held by, deposits or other liabilities in
                        or  for  the  account  of  LIBOR  Loans,  or  any  other
                        acquisition of funds by, any office of the Bank which is
                        not otherwise included in the determination of the LIBOR
                        hereunder; or

                (ii)    shall impose on the Bank any other condition;

                and the result of any of the  foregoing  is to increase the cost
                to the Bank, by an amount which the Bank deems in its reasonable
                judgment to be material,  of  maintaining  the LIBOR Loans or to
                reduce any amount receivable  hereunder in respect thereof then,
                in any case,  Borrowers  shall  promptly pay the Bank,  upon its
                demand,  any additional amounts necessary to compensate the Bank
                for such  increased cost or reduced  amount  receivable.  If the
                Bank becomes  entitled to claim any additional  amounts pursuant
                to this  subsection,  it shall promptly notify UPET of the event
                by reason of which it has become so entitled.  A certificate  as
                to any additional  amounts  payable  pursuant to this subsection
                setting forth the calculation  thereof in reasonable  detail (as
                determined by the Bank in its reasonable  discretion)  submitted
                by the  Bank to UPET  shall  be  conclusive  in the  absence  of
                manifest  error.  This covenant shall survive the termination of
                the Loans  and the  payment  of the Notes and all other  amounts
                payable hereunder.

        (b)     In the event that the Bank shall have determined that any change
                in any Requirement of Law regarding  capital  adequacy or in the
                interpretation or application  thereof or compliance by the Bank
                or any  corporation  controlling  the Bank with any  request  or
                directive  regarding capital adequacy (whether or not having the
                force of law) from any Governmental Authority made subsequent to
                the date hereof  does or shall have the effect of  reducing  the
                rate of return on the  Bank's  capital as a  consequence  of its
                LIBOR obligations hereunder to a level below that which the Bank
                or such  corporation  could have achieved but for such change or
                compliance   (taking  into  consideration  the  Bank's  or  such
                corporation's  policies with respect to capital  adequacy) by an
                amount deemed by the Bank,  in its  reasonable  judgment,  to be
                material,  then from time to time,  after submission by the bank
                to UPET of a written  request  therefor,  Borrowers shall pay to
                the Bank such  additional  amount or amounts as will  compensate
                the Bank for such reduction.  A certificate as to any additional
                amount  payable  pursuant to this  subsection  setting forth the
                calculation  thereof in reasonable  detail (as determined by the
                Bank in its  reasonable  discretion) to UPET shall be conclusive
                in the absence of manifest error.

        (c)     Upon request by the Bank, from time to time, Borrowers shall pay
                the cost of all Eurocurrency Reserve Requirements  applicable to
                the LIBOR Loans.  If the Bank is or becomes  entitled to receive
                payments  in  respect  of  Eurocurrency   Reserve   Requirements
                pursuant  to this  subsection,  it shall  promptly  notify  UPET
                thereof.  A  certificate  as to the amount of such  Eurocurrency
                Reserve  Requirements  setting forth the calculation  thereof in
                reasonable  detail (as  determined by the Bank in its reasonable
                discretion) submitted by the Bank to UPET shall be conclusive in
                the absence of manifest  error.  This covenant shall survive the
                termination  of this  Agreement and the payment of the Loans and
                all other amounts payable hereunder.

        (d)     If requested by UPET,  payments  required under this Section 4.3
                may be made in equal monthly installments over the twelve months
                following  notice by the Bank to UPET  pursuant to this  Section
                4.3.

        (e)     If payments are required  under this Section 4.3,  Borrowers may
                convert  the LIBOR  Loans so  affected  into  Prime  Rate  Loans
                subject to Section 4.4.

4.4     Indemnity.  Borrowers  agree to indemnify  the Bank and to hold the Bank
        harmless from any loss or expense which the Bank may sustain or incur as
        a consequence  of (a) default by any Borrower in payment when due of the
        principal  amount  of or  interest  on a  LIBOR  Loan,  (b)  default  by
        Borrowers in making any  prepayment  on a LIBOR Loan after  Borrowers or
        UPET have given a notice  thereof in accordance  with the  provisions of
        this  Agreement  or (c) the making of a payment,  conversion  to a Prime
        Rate Loan or  prepayment  of a LIBOR  Loan on a day which is not a LIBOR
        Determination Date with respect thereto, including,  without limitation,
        in each case, any such loss or expense arising from the  reemployment of
        funds  obtained  by the  Bank or from  fees  payable  to  terminate  the
        deposits from which such funds were  obtained.  Payments  required under
        this Section 4.4 shall be made within ten (10) days after notice thereof
        by the Bank. A certificate as to any additional  amount payable pursuant
        to this Section 4.4 setting forth the calculation  thereof in reasonable
        detail (as determined by the Bank in its reasonable  discretion) to UPET
        shall be  conclusive  in the absence of manifest  error.  This  covenant
        shall  survive  the  payment  of the Loans or the  Notes,  and all other
        amounts payable hereunder.

                    ARTICLE V: REPRESENTATIONS AND WARRANTIES

                Borrowers represent and warrant to the Bank that:

        of its incorporation, has the corporate power to own its property and to
        carry on its  business  as now being  conducted,  is duly  qualified  to
        engage in business and is in good standing as a foreign  corporation  in
        each  jurisdiction in which the character of the properties  owned by it
        or the  transaction of its business makes such  qualification  necessary
        (except where the failure to obtain such qualification does not have any
        material adverse effect on the Borrowers) and has full power,  authority
        and legal right to incur the Indebtedness and other obligations provided
        for in the Documents to which it is a party,  to execute and deliver the
        Documents  to which it is a party and to perform  and  observe the terms
        and provisions hereof and thereof. This Agreement  constitutes,  and the
        Notes when  executed and  delivered  for value will  constitute,  legal,
        valid  and  binding   obligations  of  Borrowers,   enforceable  against
        Borrowers  in  accordance  with their  respective  terms,  except as the
        foregoing   may  be  limited  by  applicable   bankruptcy,   insolvency,
        reorganization,  moratorium or similar laws affecting  enforceability of
        creditors' rights generally at the time in effect (regardless of whether
        enforcement is sought in equity or law).

5.2     Corporate Authorizations. The execution, delivery and performance of the
        Documents and the borrowing  hereunder have been duly  authorized by all
        necessary action on the part of Borrowers including, without limitation,
        the  authorization  of all partners or Boards of Directors of Borrowers,
        and all necessary  approvals of  Governmental  Authorities in connection
        therewith have been received.

5.3     Absence of  Restrictions.  The  execution,  delivery and  performance by
        Borrowers of the Documents  and the  borrowings  hereunder  will not (i)
        violate any  provision of law or the  charters or by-laws of  Borrowers,
        (ii) violate, be in conflict with, result in a breach of or constitute a
        default  under  any  order  of  any  court,  arbitrational  tribunal  or
        Governmental  Authority  or  under  any  material  mortgage,  indenture,
        contract,  undertaking  or other  agreement  to which any  Borrower is a
        party or by which  any  Borrower  or any of its  properties,  assets  or
        revenues  is bound,  (iii)  violate any  governmental  or agency rule or
        regulation  (including,  without limitation,  Regulations U and X of the
        Board of Governors of the Federal Reserve System of the United States of
        America) or (iv) result in the  creation or  imposition  of any security
        interest,  lien,  charge or other  encumbrance of any nature  whatsoever
        upon  any  of  its  properties,   assets  or  revenues,  other  than  as
        contemplated herein.

5.4     Financial  Position and Statements.  The financial  statements listed in
        Schedule 5.4, together with supporting schedules and notes, of Borrowers
        delivered  to the Bank have been  prepared in  accordance  with GAAP and
        correctly  set  forth  in all  material  respects  Borrower's  financial
        position  as at or for the  periods  shown  therein  and show all  known
        material liabilities, direct or contingent, as of such dates. Except for
        the payment of the expenses of the transactions  contemplated hereby and
        by the Merger  Plan,  there  have been no  material  adverse  changes in
        Borrowers'  financial  position  since  the date of the  latest  of such
        financial statements.

5.5     Litigation.  Except as provided in Schedule  5.5,  there are no material
        actions,  suits,  proceedings  or claims  pending  against or materially
        affecting  any Borrower  which,  if adversely  determined,  would have a
        material  adverse effect on the financial  condition or business of such
        Borrower.

5.6     Bankruptcy Plan.

        (a)     Bankruptcy  Approvals.  Each  of the  Borrowers,  to the  extent
                applicable,  has obtained all necessary and requisite authority,
                consents and approvals of the United States Bankruptcy Court for
                the District of Delaware (the "Bankruptcy Court") in the Chapter
                11 bankruptcy  proceedings styled United Petroleum  Corporation,

                and  consummate  the  transactions  contemplated  in  this  Loan
                Agreement and in the Merger Plan, including, without limitation,
                incurring of the indebtedness and granting of the liens provided
                for herein.

        (b)     Effectiveness of Plan. The Second Amended Plan of Reorganization
                for UPET (the "Plan") and the Order  Confirming the Amended Plan
                by  the  Bankruptcy  Court  (the  "Confirmation  Order")  in the
                Bankruptcy  Proceedings  (1) are in full force and effect,  have
                not been  withdrawn,  modified or amended as of the date hereof,
                and are enforceable in accordance with their  respective  terms,
                (2) are not the  subject of any motion  for  reconsideration  or
                rehearing,  whether under Rules 59 or 60 of the Federal Rules of
                Civil Procedure or otherwise, and (3) are not the subject of any
                appeal,  extension of time for appeal,  stay  pending  appeal or
                similar pleading.

        (c)     Effective   Date.  All  of  the  conditions   precedent  to  the
                occurrence  of the  Effective  Date,  as  defined  in the  Plan,
                including  as set  forth in  Section  13.1 and 13.2  thereof  or
                otherwise,  have  been  satisfied  as of the  date  hereof.  The
                Effective  Date,  as  defined  in  the  Plan,  and  all  of  the
                transactions  or events  described  in Section 8.17 of the Plan,
                including substantial consummation of the Plan, have occurred as
                of the  date  hereof  or  will  occur  simultaneously  with  the
                consummation of the  transactions  contemplated  under this Loan
                Agreement.

        (d)     Compliance  With  Plan.  Each of the  Borrowers,  to the  extent
                applicable, has fully complied with all of the provisions of the
                Plan,  and the Order and the United  States  Bankruptcy  Code in
                connection with the transactions  contemplated herein, including
                the incurrence of the indebtedness herein or the granting of the
                liens provided for herein. To the extent applicable, no Borrower
                is in default of the Plan,  the Order or the  provisions  of the
                United States Bankruptcy Code or will be in default thereof as a
                result of the transactions  contemplated  herein,  including the
                incurrence  of the  indebtedness  herein or the  granting of the
                liens provided for herein.

        (e)     Reasonably  Equivalent Value. Each of the Borrowers has received
                reasonably  equivalent  value in exchange  for the  indebtedness
                incurred under this Loan Agreement and in exchange for the liens
                granted pursuant hereto.  Each of the Borrowers is solvent as of
                the date  hereof and will not be made  insolvent  as a result of
                the  transactions   contemplated  hereunder,  the  term  solvent
                meaning that each Borrower's property,  at a fair valuation,  is
                greater than the sum of its debts,  including  the  indebtedness
                being  incurred  hereunder.  Each of the Borrowers  does not and
                will not, as a result of the transactions hereunder,  have or be
                left with an  unreasonably  small  capital with which to conduct
                its  business.  Each of the Borrowers do not intend to incur and
                will  not  incur,  including  as a  result  of the  transactions
                contemplated   hereunder,   debts  that  would  be  beyond  such
                Borrower's ability to pay as they matured.

        (f)     Notice.  Each of the Borrowers,  to the extent  applicable,  has
                provided,  or  caused  to be  provided,  proper  notice  of  the
                Bankruptcy  Proceedings  and the related claims bar date therein
                to  all  known  and  suspected  creditors,  whether  secured  or
                unsecured,  liquidated  or  unliquidated,  contingent  or fixed,
                priority or  non-priority  or disputed or  undisputed,  and that
                each Borrower, to the extent applicable, has fully complied with
                the  provisions  of that certain Order of the  Bankruptcy  Court

                and Manner of Notice of Bar Date,  dated  February 17, 1999 (the
                "Bar Date  Order").  No  Borrower  is aware of, or has reason or
                basis to be aware of, any  claimant or creditor or UPET that has
                not received  proper notice of the Bar Date Order, or the claims
                bar date contained therein.

5.7     Title to Properties;  No Liens.  Except as provided in Schedule  5.7(a),
        Borrowers  have  good and  marketable  title to all of their  respective
        properties and assets and,  except as provided in Schedule  5.7(b) or as
        permitted or required by the provisions hereof,  none of the properties,
        assets and  revenues of  Borrowers  are subject to any  mortgage,  lien,
        security interest,  pledge or other charge or encumbrance or any similar
        arrangement of any kind.

        filed,  or caused to be filed,  all tax returns which are required to be
        filed by any of them,  and have  paid or  caused to be paid all taxes as
        shown on such returns or on any  assessment  received by any of them, to
        the extent that such taxes have become due.

5.9     Agreements.  Except as provided in Schedule 5.9, none of Borrowers is in
        default,  in any manner which would  materially and adversely affect any

        or otherwise),  in the performance,  observance or fulfillment of any of
        the obligations,  covenants or conditions  contained in any agreement or
        instrument  to  which  it is a  party  or by  which  it or  any  of  its
        properties, assets or revenues is bound.

        Borrowers in connection  with the  negotiation  and  preparation of this
        Agreement  are correct and taken as a whole do not contain any omissions

        Compliant with respect to its computers, computer systems and codes.

5.12    Year 2000 Indemnity.  Borrowers  hereby  indemnify the Bank and hold the

        representations  and  warranties  made herein or otherwise in writing by
        Borrowers in connection  herewith being incorrect,  false or misleading.
        This covenant shall survive the payment of the Loans and cancellation of
        the Notes, and all other amounts payable hereunder.

        Assignment or spreader shall be in recordable form and shall be recorded
        in the  appropriate  public  or land  records  simultaneously  with  the
        recording of a short form or memorandum of such  additional  Lease;  and
        (b) either  cause any such  additional  Lease to include  the  following
        provisions  or  obtain  the  landlord's  specific  consent  to the  Bank
        containing the following provisions:

        (i) that the  tenant's  interest in the Lease is freely  assignable  and
        that  the  landlord's   consent  is  not  required  for  the  collateral
        assignment  or other  pledge of the  tenant's  interest  in the lease to
        tenant's lender (the "Leasehold Mortgagee");

        (ii) that the  landlord  agrees  that any and all liens of the  landlord
        against the  Collateral  for the payment of rent,  whether  statutory or
        otherwise,  are  automatically  subject and  subordinate to the security
        interest  in the  Collateral  granted  by the  tenant  in  favor  of the
        Leasehold Mortgagee;

        (iii) that a short form or memorandum  of the Lease in  recordable  form
        shall  be  executed  by  the  parties  and  promptly   recorded  in  the
        appropriate public or land records;

        (iv) that the Lease shall not be subordinate  to any mortgage  placed on
        the  landlord's  interest in the lease  premises  unless the  landlord's
        lender enters into a  non-disturbance  agreement with the tenant in form
        satisfactory to the tenant;

        (v) that the  landlord  agrees  (A) not to amend or modify  the Lease or
        accept a  surrender  of the  Lease  without  the  Leasehold  Mortgagee's
        written consent, which shall not be unreasonably withheld; (B) to notify
        the  Leasehold  Mortgagee  in  writing  if the  tenant  fails to pay the
        required  rent when due or otherwise  commits a default  under the Lease
        that would entitle the landlord to terminate the Lease;  (C) to accept a
        cure of the tenant's default of offered by the Leasehold Mortgage within
        30 days after the landlord's written notice to the Leasehold  Mortgagee;
        and  (D) to  accept  the  Leasehold  Mortgagee  or its  designee  as the
        landlord's  new  tenant  under  the  Lease  if the  Leasehold  Mortgagee
        exercises its rights against the tenant under its collateral  assignment
        of the Lease,  provided that the tenant's  defaults  under the Lease are
        cured and the new tenant assumes the Lease; and

        (vi) that the landlord consents and agrees that the Leasehold  Mortgagee
        shall have the right to enter the lease premises where the Collateral is
        located for the purpose of removing,  selling or otherwise  dealing with
        the  Collateral;   provided  that  the  Leasehold   Mortgagee  shall  be
        responsible  for  any  cost  of  repair  of  physical  injury  (but  not
        diminution of value)  caused by any such removal.  Even if the Leasehold
        Mortgagee  or its designee  does not elect to cure the tenant's  default
        and assume the Lease as landlord's new tenant as described  above,  then
        the Leasehold  Mortgagee shall nevertheless have up to 30 days after the
        landlord's  notice of default in which to remove the Collateral from the
        lease  premises,  provided  that  the  Leasehold  Mortgagee  pays to the
        landlord on demand all rent accruing  under the Lease from the date such
        notice is received until the Collateral is removed.

        respects  with all  statutes,  rules,  regulations,  guidelines or other
        requirements  having the force of law which now or at any time hereafter
        may be  applicable  to any of  Borrowers,  provided  that a Borrower may
        defer  observation  and  compliance  with  requirements  as to  which it
        contests  the  validity  or  application  thereof  in good  faith and by
        appropriate  proceedings  if such  deferral does not  materially  hinder
        Borrowers operations.

6.13    Obtain Approvals.  Promptly obtain each consent, license,  authorization
        or approval and make each filing or  registration  which hereafter shall
        be either  necessary or desirable to enable each Borrower to comply with
        its obligations hereunder,  and promptly furnish evidence thereof to the
        Bank.

        event within fifteen (15) days after becoming aware of the occurrence of

                lease,  or by which any  obligation  for the payment of borrowed
                money is created, if the effect of such default is to cause such

                more than  thirty  (30) days  unless  during  such  period  such
                judgment shall be effectively stayed, on appeal or otherwise; or

                property  or any order for relief is entered  with  respect to a
                Borrower  under any  bankruptcy  code or any  similar law of any
                jurisdiction and the same shall remain undischarged for a period
                of sixty (60) days; or

        (g)     Condemnation. All or a substantial part of a Borrower's property
                is condemned,  seized or otherwise  appropriated,  or custody of
                such property is assumed by any Governmental  Authority or court
                or  other  Person  purporting  to act  under  the  authority  of
                government of any jurisdiction,  or a Borrower is prevented from
                exercising  normal control over all or a substantial part of its
                property and such  default is not remedied  within 30 days after
                it occurs; or

        (h)     Change of  Control.  Mr.  Jose Bared  disposes of shares of UPET
                which the Bank, after  consultation with UPET,  determines to be
                adverse to the best  interest  of  Borrowers  or Mr.  Jose Bared
                ceases to be the Chief Executive Officer of UPET and UPET Group,
                and the Bank after consultation with UPET determines such action
                to be adverse to the best interest of Borrowers; or

        (i)     Enforceability.  This Agreement, or any provision hereof, at any
                time  after  its  execution  and  delivery  and for  any  reason
                whatsoever  ceases  to be in full  force and  effect,  valid and
                enforceable  both in the  jurisdictions  in which the  Borrowers
                operate and in the State of Florida,  or  Borrowers  at any time
                fail to agree that this Agreement and all provisions  hereof are
                in full force and effect,  valid,  and  enforceable  both in the
                jurisdictions in which the Borrowers operate and in the State of
                Florida;

        then the Bank by notice to UPET may declare the entire unpaid  principal
amount of the  Loans to be  immediately  due and  payable  without  presentment,
demand,  protest or other notice of any kind, all of which are hereby  expressly
waived.

10.2    Exercise of Rights.  Upon the  occurrence  of an Event of Default and at
        any  time  thereafter,  the  Bank  shall  have  the  right  in its  sole
        discretion  to determine  which  rights,  security,  liens,  guarantees,
        security  interests  or  remedies  it  shall  retain,  pursue,  release,
        subordinate, modify or take any other action with respect to, without in
        any way  modifying or  affecting  any of the other of them or any of its
        rights  hereunder.  Notwithstanding  any other rights which the Bank may
        have under applicable law and hereunder, Borrowers agree that, should at
        any time an Event of Default occur or be continuing, the Bank shall have
        the right to apply (including, without limitation, by way of setoff) any
        of Borrowers' property held by, or thereafter coming into possession of,
        the Bank (including,  without limitation, deposit account balances) to a
        reduction of Indebtedness of Borrowers to the Bank.

                            ARTICLE XI: MISCELLANEOUS

11.1    Notices.  Except as otherwise  specified herein, all notices,  requests,
        demands or other  communications to or upon the parties hereto under the
        Documents shall be deemed to have been duly given or made when delivered
        in  writing  (including  telecommunications)  to the party to which such
        notice,  request, demand or other communication is required or permitted
        to be given or made under this  Agreement,  at the address or  facsimile
        number set forth opposite the name of such party on the signature  lines
        set forth below,  or at such other  address or  facsimile  number as the
        parties  hereto may hereafter  specify to the other in writing.  Written
        notices shall be deemed  delivered  upon receipt if delivered by hand or
        five Business Days after mailing.  Notices  provided by any of the other
        means referred to above shall be deemed delivered upon receipt.

11.2    Waiver of Rights. No failure to exercise and no delay in exercising,  on
        the part of the Bank, any right,  power or privilege under the Documents
        shall  operate  as a waiver  thereof,  nor shall any  single or  partial
        exercise  thereof  preclude any other or further exercise thereof or the
        exercise of any other right, power or privilege.

11.3    Cumulative   Remedies,   Conflicts.   Each  of  the  Documents  and  the
        obligations of Borrowers hereunder and thereunder are in addition to and
        not in substitution for any other obligations or security  interests now
        or  hereafter  held by the Bank and shall not operate as a merger of any
        contract  or debt or suspend  the  fulfillment  of or affect the rights,
        remedies  or powers of the Bank in  respect of any  obligation  or other
        security interest held by it for the fulfillment thereof. The rights and
        remedies  provided in the Documents are  cumulative and not exclusive of
        any other  rights or remedies  provided by law. If any  conflict  exists
        between  the terms of this  Agreement  and the terms of any of the other
        Documents to which UPET, UPET Group, F.S. Stores, F.S. Gas, F.S. Non-Gas
        or REWJB Gas are parties, the terms of this Agreement shall control.

11.4    Successors;  Governing  Law.  This  Agreement  shall be binding upon and
        inure to the benefit of  Borrowers  and the Bank,  and their  respective
        successors  and  assigns,  except that none of  Borrowers  may assign or
        transfer its rights  hereunder  without the prior written consent of the
        Bank.  This  Agreement  shall be governed by and construed in accordance
        with the laws of the State of Florida.

11.5    Consent to Jurisdiction; Process Agent.

        (a) Borrowers hereby irrevocably submit to the nonexclusive jurisdiction
        of any Florida  State or Federal  court  sitting in  Miami-Dade  County,
        Florida in any action or  proceeding  arising out of or relating to this
        Agreement  and the other  Documents,  and Borrowers  hereby  irrevocably
        agrees  that all claims in respect of such action or  proceeding  may be
        heard and  determined  in such  Florida  State or  Federal  court.  Each
        Borrower hereby  irrevocably  appoints CT  Corporation,  1200 South Pine
        Island Road,  Plantation,  Florida  33324,  its  successors or any other
        person acting on behalf of such person ("Process  Agent"),  as its agent
        and  attorney-in-fact to receive on its behalf of its property,  service
        of copies of the summons and  complaint  and any other process which may
        be served in any such action or proceeding.  Such service may be made by
        mailing or  delivering  a copy of such  process to a Borrower in care of
        the Process Agent at the Process Agent's address set forth above or such
        other  address as the Process  Agent shall  designate  in writing to the
        Bank, and each Borrower  hereby  irrevocably  authorizes and directs the
        Process Agent to accept such service on its behalf.

        (b) Borrowers hereby  irrevocably  waive any objection which any of them
        may now or hereafter have to the laying of venue of any suit,  action or
        proceeding  arising out of or relating to this Agreement  brought in any
        Florida State or Federal court  sitting in Miami-Dade  County,  Florida,
        and  hereby  further  irrevocably  waives  any claim that any such suit,
        action or  proceeding  brought in any such court has been  brought in an
        inconvenient forum.

        (c) Nothing in this  Section  11.5 shall affect the right of the Bank to
        serve legal  process in any other manner  permitted by law or affect the
        right of the Bank to bring any action or proceeding against Borrowers or
        their property in the courts of other jurisdictions.

11.6    Currency  Conversion.   This  is  a  credit  transaction  in  which  the
        specification  of Dollars is of the  essence,  and Dollars  shall be the
        currency  of account  in all  events.  The  payment  obligations  of the
        Borrowers  under this  Agreement  and the other  Documents  shall not be
        discharged  by an amount paid in another  currency or in another  place,
        whether  pursuant  to a judgment  or  otherwise,  to the extent that the
        amount so paid on  conversion  to  Dollars  in  accordance  with  normal
        banking  procedures  does not yield the amount of Dollars due hereunder.
        Notwithstanding  the  foregoing,  if for the  purpose  of  obtaining  or
        enforcing  judgment  in any court it is  necessary  to convert a sum due
        hereunder in Dollars into another currency (the "Second Currency"),  the
        rate of  exchange  which  shall  be  applied  shall  be that at which in
        accordance  with  normal  banking  procedures  the Bank  could  purchase
        Dollars with the Second  currency on the Business Day preceding  that on
        which final  judgment is given.  If payment of any sum due  hereunder is
        made to or  received  by the Bank,  whether by  judicial  judgment  (and
        notwithstanding  the rate of  exchange  actually  applied in giving such
        judgment), or otherwise, in a Second Currency, the obligations hereunder
        of Borrowers  shall be discharged only in the net amount of Dollars that
        on the Business Day following receipt by the Bank of any sum adjudicated
        to be due in a Second  Currency,  the recipient in  accordance  with its
        normal bank procedures is able to lawfully  purchase with such amount of
        Second  Currency.  To the extent  that the Bank is not able to  purchase
        sufficient  Dollars with such amount of Second Currency to discharge the
        Dollar obligations to the Bank, the obligations of Borrowers to the Bank
        shall not be discharged with respect to such  difference,  and Borrowers
        agrees that any such undischarged  amount will be due as a separate debt
        and shall not be affected by payment of or judgment  being  obtained for
        any other sums due under or in respect of this Agreement.  To the extent
        that the Bank is able to  purchase an amount in Dollars in excess of the
        amount  necessary to discharge such Dollar  obligations,  the Bank shall
        promptly remit such excess to Borrowers.

11.7    Amendments.  The terms of this Agreement may not be amended, modified or
        waived except by written agreement between Borrowers and the Bank.

11.8    Usury. Anything herein to the contrary notwithstanding,  the obligations
        of  Borrowers to pay interest  shall be subject to the  limitation  that
        payment of interest  shall not be required to the extent that receipt of
        such payment by the Bank would be contrary to the  provisions of any law
        applicable to the Bank  limiting the maximum rate of interest  which may
        be charged or collected by the Bank.

11.9    Survival of Agreements. All covenants,  agreements,  representations and
        warranties made herein and in the certificates delivered pursuant hereto
        shall survive the making by the Bank of the credit  herein  contemplated
        and shall  continue  in full force and effect so long as such  credit is
        outstanding and unpaid.

11.10   Severability.  Any provision hereof which is prohibited or unenforceable
        shall  be  ineffective  only  to  the  extent  of  such  prohibition  or
        unenforceability without invalidating the remaining provisions hereof.

11.11   Descriptive Headings. The captions in this Agreement are for convenience
        of reference only and shall not define or limit the provisions hereof.

11.12   Waiver of Trial by Jury. BORROWERS AND BANK EACH HEREBY WAIVES ITS RIGHT
        TO TRIAL BY JURY IN ANY LITIGATION  BASED HEREON OR ARISING OUT OF OR IN
        CONNECTION WITH ANY AGREEMENT, DOCUMENT OR INSTRUMENT OR ANY TRANSACTION
        CONTEMPLATED HEREBY.

11.13   Confidentiality.  The Bank  agrees  (on behalf of itself and each of its
        Affiliates, directors, officers, employees, and representatives) to keep
        confidential,  in accordance  with its customary  procedures of handling
        confidential  information of the same nature and in accordance with safe
        and sound banking practices,  any non-public  information supplied to it
        by Borrowers or any of their  Subsidiaries  pursuant to this  Agreement;
        provided, however, that nothing herein shall limit the disclosure of any
        such information (i) to the extent required by statute, rule, regulation
        or  judicial  process,  (ii) to  counsel  for  the  Bank so long as such
        counsel confirms it shall keep the non-public  information  confidential
        in accordance with these provisions,  (iii) to bank examiners,  auditors
        or  accountants  or to any other  regulatory  agency or body with proper
        authority  (including  non-governmental  regulatory agencies or bodies),
        (iv) in  connection  with any  litigation  to which  the Bank is a party
        where  disclosure of such  information is, in the opinion of counsel for
        the Bank,  necessary or advisable in connection with any action,  claim,
        suit or  proceeding,  directly or  indirectly,  involving or potentially
        involving  the Bank and  arising  out of,  based  upon,  relating  to or
        involving this Agreement or any Note, or any  transactions  contemplated
        hereby or arising  hereunder,  (v) to any assignee or participant of the
        Bank's rights  hereunder,  so long as such assignee or participant first
        acknowledges  that it is bound by the  provisions of this Section 10.13,
        or (vi) to any credit agency that rates the  financial  condition of the
        Bank or the claims paying ability of the Bank or the financial condition
        of any Borrower. To the extent disclosure is required under clauses (i),
        (iii) and (iv) above,  the Bank  agrees to use its best  efforts to give
        the Borrower prompt prior notice thereof if allowed by law.

        IN WITNESS WHEREOF,  the parties hereto have caused this Agreement to be
executed by their duly authorized officers as of the date first written above.
