      reimburse such Persons as have actually supplied labor, materials or
      services in connection with or incidental to construction of the DSN
      Plant, or to reimburse Borrower in the event Borrower shall have
      already paid such Persons.  In no event shall Lender be required to
      disburse any amount which, in Lender's reasonable opinion, will
      either (i) reduce the total undisbursed amount of the Loan below the
      amount necessary to pay for the balance of the work, labor and
      materials necessary fully to complete construction of the DSN Plant
      in accordance with the Plans and Specifications, or (ii) reduce the
      undisbursed amount of Loan proceeds allocated to the cost category
      described in any paragraph contained in the Disbursement Schedule
      below the amount which Lender reasonably deems sufficient to pay in
      full the costs to which such amount is allocated.  In the event any
      amount in a cost category of the Disbursement Schedule is deficient,
      and Borrower has not made alternative payment arrangements for the
      costs in question, then upon ten (10) days' written notice from
      Lender, Borrower shall furnish Lender with paid invoices, bills and
      receipts indicating that Borrower has paid, from Borrower's own
      funds, for the costs of completing the construction of the DSN Plant
      or the costs in the cost category in question, as the case may be, in
      a sufficient amount to make the undisbursed amount of the Loan or the
      undisbursed portion thereof under the cost category in question
      sufficient to pay for the entire balance of the costs of completing
      the construction of the DSN Plant or the entire balance of the costs
      in such cost category, but only if such work has been performed and
      materials have been provided.
  
                  (e)   Limitations on Disbursements.  Disbursements of
      Loan proceeds shall be made by Lender only to defray costs actually
      incurred by Borrower and in accordance with the Disbursement
      Schedule.  Disbursements on account of the direct costs of
      constructing the DSN Plant shall be limited to the lesser of (i) the
      actual cost to Borrower of work and labor performed on the DSN Plant
      and materials incorporated into the DSN Plant or suitably stored at
      the DSN Plant Location or (ii) the actual value (as determined by
      Lender in its reasonable discretion) of said work and labor performed
      and materials stored; disbursements on account of indirect or "soft"
      costs relating to the construction of the DSN Plant, the Loan, the
      preparation of the Plans and Specifications, and all of the other
      transactions contemplated hereby shall be limited to the actual
      amounts of such costs as indicated by invoices, statements, vouchers,
      receipts or other written evidence satisfactory to Lender.
  
                  (f)   Continuation and Date-Down Endorsements.  After
      recordation of the Leasehold Mortgage and as a condition precedent to
      each disbursement under the Loan after the initial advance, Borrower
      shall, at its own cost and expense, deliver or cause to be delivered
      to Lender from time to time such continuation and date-down
      endorsements to be attached to the Title Policy in form and substance
      satisfactory to Lender, as Lender deems necessary to insure the
      priority of the Leasehold Mortgage as a valid first priority lien on
      the DSN Plant Location and the DSN Plant as of the date of and
      including the amount covered by each such disbursement, and Borrower
      agrees to furnish to the title insurer such surveys and other
      information as are reasonably required by Lender or the title insurer
      to enable the title insurer to issue such endorsements to Lender.
  
                  (g)   Change Orders.  Borrower shall not permit any
      amendments or modifications of the Plans and Specifications, the
      Construction Contract or any subcontracts, or the performance of any
      work pursuant to such amendments or modifications, which individually
      exceed $250,000 or, when added to the cumulative amount of all net
      increases in the prices payable under the Construction Contract and
      all such subcontracts resulting from all such amendments and
      modifications theretofore permitted by Borrower, would result in a
      net increase in the total price payable under all such subcontracts
      in excess of $750,000.
  
                  (h)   Other General Conditions.  No Request for Advance
      will include (i) any amounts previously disbursed hereunder, (ii) any
      costs not approved, certified or verified as provided above,
      (iii) any costs for which payment reimbursement was previously
      requested by Borrower and for which proof of payment has been
      requested but not yet received by Lender, and/or (iv) any real estate
      taxes, mechanics' liens, security interests, claims or other charges
      against the Collateral, or any interest, fees or other costs which
      Borrower may have failed to pay in accordance with this Agreement or
      the other Loan Documents.  If Lender considers that its best interest
      and the best interest of the completion of the construction lies in
      accelerating the amounts to be advanced hereunder, it shall be
      entitled to do so, and no such advance shall be deemed to be a waiver
      of any condition contained herein.
  
            Section 2.3  Repayment of the Loan.  The Borrower promises to
  repay the Loan as follows:
  
                        (a)   During the Construction Period, monthly

      provided, however, that if the Construction Period ends on the DSN
      Plant Completion Date, then the Loan shall be converted to a term
      Loan and shall be extended for a period (the "Term Out Period")
      commencing on the day immediately succeeding the last day of the
      Construction Period and ending on the date which is eight-four (84)
      months after such date, subject to the following terms and
      conditions:
  
             (i)        no uncured Default has occurred and is
            continuing, and no material adverse change in the business,
            financial condition or operations of Borrower, any Guarantor or
            EDC shall have occurred;
            
                      (ii)        any undisbursed Loan proceeds existing

            Borrower shall have no further right to request or receive any
            further disbursements of Loan proceeds, provided, that this
            limitation shall not apply if Borrower demonstrates to Lender
            that additional conforming costs and expenses have been
            incurred in connection with the DSN Plant and Lender approves
            such additional costs and expenses for payment from such
            undisbursed Loan Proceeds prior to the commencement of the Term
            Out Period;
            
                      (iii)       Lender shall have determined, based
            upon an appraisal of the DSN Plant conducted at Borrower's sole
            expense by an independent appraiser selected by Lender, that
            the Fair Market Value of the DSN Plant and the Equipment equals
            or exceeds the outstanding principal balance of the Loan.  This
            shall be performed and completed not later than January 1,
            1995;
            
                      (iv)        LSB and certain of its subsidiaries
            shall have entered into a new $75,000,000 credit facility with
            BankAmerica Business Credit or affiliate thereof on terms and
            conditions reasonably acceptable to Lender;
            
                       (v)        commencing on the first day of the
            first month which begins not less than 31 days after the last
            day of the Construction Period and thereafter on the first day
            of each subsequent month, Borrower shall pay to Lender during
            the Term Out Period in eighty-four (84) consecutive, equal
            monthly payments of principal and interest, calculated by fully
            amortizing the outstanding principal balance of the Loan as of
            the commencement of the Term Out Period over an 84-month period
            at the applicable interest rate set forth in Section 2.4; and 
            
                      (vi)        the principal balance outstanding under
            the Note, and all accrued and unpaid interest not sooner paid
            when due under the Note, and all other Obligations of Borrower
            owing under any and all of the Loan Documents, shall due and
            payable in full on the last day of the Term Out Period.
            
                        (c)   In the event the Loan is not converted to a
      term Loan because Borrower has chosen to finance the DSN Plant with a
      lender other than Lender, not due to any default by Lender, then in
      addition to all other sums owing on the date on which the
      Construction Period ends, Borrower shall pay to Bank a termination
      fee equal to five percent (5%) of the outstanding principal balance
      of the Loan as of the date on which the Construction Period ends.
  
  The Borrower's obligation to pay all amounts payable hereunder is absolute
  and unconditional and shall not be affected by any circumstance of any
  character whatsoever, including (i) any setoff, counterclaim, recoupment,
  defense, abatement or reduction or any right which the Borrower may have
  against the Lender, the manufacturer or supplier of any of the Equipment or
  anyone else for any reason whatsoever; (ii) the invalidity, enforceability
  or disaffirmance of this Agreement or any other Loan Document related
  hereto; or (iii) the prohibition of or interference with the use or
  possession-by the Borrower of all or any part of the DSN Plant Location or
  the Equipment, for any reason whatsoever.
  
            Section 2.4  Interest Charges.  During the Construction Period,
  the outstanding principal balance of the Loan shall bear interest at a rate
  per annum equal to the Libor Rate plus 3.10%.  During the Term Out Period,
  the outstanding principal balance of the Loan shall bear interest at a per
  annum rate equal to the Treasury Rate plus 2.70%.  In each instance,
  interest shall be calculated on the basis of a 360-day year consisting of
  twelve 30-day months.
  
            Section 2.5  Late Charge Rate.  In the event the Borrower fails
  to pay any amount hereunder when due, the amount due shall bear charges
  thereon calculated at the Late Charge Rate.  At any time when any Event of
  Default has occurred, irrespective of any cure periods, and continues for
  over ten (10) days, the Borrower will pay interest on the Loan at the Late
  Charge Rate.
  
            Section 2.6  Maximum Interest.  In no event shall the interest
  charged with respect to the Obligations exceed the maximum amount permitted
  under applicable law.  Notwithstanding anything to the contrary herein or
  elsewhere, if at any time the rate of interest called for hereunder or
  under the Note or other Loan Document (the "Stated Rate") exceeds the
  highest rate of interest permissible under any applicable law (the "Maximum
  Lawful Rate"), then for so long as the Maximum Lawful Rate would be so
  exceeded, the rate of interest payable shall be equal to the Maximum Lawful
  Rate; provided, however, that if at any time thereafter the Stated Rate is
  less than the Maximum Lawful Rate, the Borrower shall, to the extent
  permitted by law, continue to pay interest at the Maximum Lawful Rate until
  such time as the total interest received by the Lender is equal to the
  total interest which the Lender would have received had the Stated Rate
  been (but for the operation of this provision) the interest rate payable. 
  Thereafter, the interest rate payable shall be the Stated Rate unless and
  until the Stated Rate again exceeds the Maximum Lawful Rate, in which event
  this provision shall again apply.
  
            Section 2.7  Expenses.  The Borrower agrees to pay on demand
  all reasonable out of pocket costs and expenses (including reasonable
  legal, appraisal, accounting, auditing and similar fees) incurred at any
  time, before or after the Obligations are paid in full, in connection with
  (i) the enforcement, attempted enforcement, amendment or termination of
  this Agreement or any of the other Loan Documents, the performance of any
  of the Borrower's duties under this Agreement and the other Loan Documents
  or any exercise by Lender of its rights and remedies under this Agreement
  or any other of the Loan Documents, including in connection with a
  reorganization or bankruptcy reorganization of the Borrower or any
  Affiliate; (ii) the filing or recordation of all documents or instruments
  relating to the Collateral; (iii) realizing upon or protecting any
  Collateral and enforcing and collecting any Obligations or guaranty
  thereof; and (iv) any Default or Event of Default.  The Borrower also
  agrees to reimburse the Lender, on the Funding Date, for its legal fees for
  outside counsel plus any appraisal fees, recording and search fees and
  related expenses, including travel and other out of pocket expenses of the
  Lender's agents and its counsel, incurred by it in connection with the
  preparation, negotiation, execution, closing and delivery of the Loan
  Documents.
  
            Section 2.8  Prepayment.  No prepayment of the Loan shall be
  permitted during the Construction Period or prior to the date which is
  forty-two (42) months after the date on which the Term Out Period begins. 
  Thereafter, provided no Default has occurred and is continuing, the
  Borrower may prepay the Loan in whole, but not in part, on the first day of
  any month, upon at least thirty (30) Business Days' prior written notice to
  the Lender.  Such prepayment of the Loan shall be accompanied by the
  payment of all principal, all accrued but unpaid interest on the Loan to
  the date of prepayment and all outstanding and unpaid costs, fees and
  expenses.  In addition, the prepayment of the Loan shall be made with a
  prepayment fee in an amount equal to the greater of (a) two percent (2.0%)
  of the outstanding principal balance of the Loan being prepaid, or (b) the
  excess, if any, of (i) the present value of the principal and interest
  payments which would have been payable during the remainder of the Term Out
  Period in the absence of the prepayment, using a discount rate equal to one
  percent (1.0%) plus the yield to maturity, as of the Third Business Day
  prior to the date on which the prepayment is made, on U.S. Treasury
  Securities having a remaining term to maturity closest to the remaining
  average life of the Loan, as such yield to maturity is reported on page 5
  ("U.S. Treasury and Money Markets") of the information ordinarily provided
  by Telerate Systems Incorporated, over (ii) the principal amount being
  prepaid.
  
            Section 2.9  Conditions of Lending.  The obligation of the
  Lender to make the initial and any subsequent advance under the Loan is
  subject to the prior satisfaction (or waiver in writing and signed by

  those Permitted Liens and those liens which by law are accorded a first
  priority, the Borrower shall take all action necessary to grant the Lender
  a valid first priority lien on and security interest in all Collateral on
  the Funding Date, and to maintain at all times the validity,

  thereof, or be negligent in the care and use thereof and will make all
  necessary replacements thereof and repairs thereto.  The Borrower shall
  promptly inform the Lender of any material additions to such Equipment and
  of any material loss, damage, or destruction of such Equipment.  The
  Borrower will not permit any Equipment to become a fixture to any real
  property or an accession to any other personal property, unless the Lender
  has a first priority perfected Security Interest in such real or personal
  property or has been provided with such waivers or consents as the Lender
  may reasonably require.  The Borrower shall, promptly upon the Lender's
  request, deliver to Lender any and all evidence of ownership of such
  Equipment.
  
            Section 4.2  No Lender Liability.  The Lender shall have no
  duty of care with respect to any Collateral unless and until it takes the
  same into its own possession or control.  The Lender shall be deemed to
  have satisfied its duty of due care with respect to Collateral in its
  custody and control if it accords to such Collateral treatment
  substantially equal to the treatment the Lender accords its own property,
  or if the Lender takes such action with respect to the Collateral as the
  Borrower requests in writing, but no failure to comply with any such
  request nor any omission to do any such act requested by the Borrower shall
  be presumptively deemed, from that failure or omission, an absence of
  reasonable care.  The Lender shall not be responsible or liable for any
  shortage, discrepancy, damage, loss or destruction of any part of the
  Collateral wherever the same may be located and regardless of the cause
  thereof, unless caused by the Lender's gross negligence or willful
  misconduct.  The Lender does not, by anything contained herein or in any
  other Loan Document or otherwise, assume any obligation of the Borrower
  under the Ground Lease, the Ground Sublease, or the DSN Plant Equipment
  Lease or any other contract or agreement assigned to Lender or in which
  Lender is granted a security interest, and the Lender shall not be
  responsible in any way for the performance by the Borrower of any of the
  terms and conditions thereof.

      and proper manner, will comply with and conform to all governmental
      laws, rules and regulations relating thereto, and will cause the
      Equipment to be operated properly or in substantial accordance with
      the manufacturer's or supplier's instructions or manuals and only by
      competent and duly qualified personnel.
  
                  (b)   The Borrower shall not move any of the Equipment
      from the DSN Plant Location without the prior written consent of CIT.
  
                  (c)   Upon Lender's written request and at the Borrower's
      sole expense, the Borrower shall attach to each item of Equipment a
      notice satisfactory to Lender disclosing Lender's security interest
      in such item of Equipment.

  limitation any stockholders, trustees or holders of Indebtedness of the
  Borrower), is required in connection with such authorization, execution,
  delivery and performance by the Borrower or the consummation of the
  transactions contemplated hereby or thereby.  Such Loan Documents have been
  duly authorized, executed and delivered by or on behalf of the Borrower,
  and constitute the legal, valid and binding Obligations of the Borrower and

  terms.

  and delivered by or on behalf of such Guarantor, and constitutes the legal
  valid and binding obligations of such Guarantor and is enforceable against

  notice of default under the Lease or the Equipment Lease (as applicable)
  which default has not been waived or cured.
  
            Section 5.6  Title to the DSN Plant and Equipment; Security
  Interest.  Except for the Security Interest and Permitted Liens and all

  Equipment Lease, the Borrower has good, and merchantable title to the DSN
  Plant and all Equipment and other Collateral, and neither the DSN Plant nor
  any of such Equipment nor any other Collateral is or will be subject to any
  Lien.   The provisions of the Loan Documents create legal, valid and
  enforceable security interests in and liens on the DSN Plant and all
  Equipment and other Collateral, and the Loan Documents and such UCC and
  real property filings create a perfected and continuing first priority
  security interest upon the DSN Plant and all the Equipment and other

  Borrower and all third parties.

  equal to the greater of the full replacement value thereof, or 100% of the
  outstanding balance of the Loan.  The Borrower shall also maintain
  (a) builder's all risk completed value hazard insurance covering 100% of
  the replacement cost of the DSN Plant and Equipment during the course of
  construction in the event of fire, lightning, windstorm, earthquake,

  risk" policies in the area where the DSN Plant is located (including loss
  by flood if the DSN Plant is located in an area designated as subject to
  the danger of flood); (b) product liability insurance in an amount
  customary for the businesses conducted by the Borrower; and (c) general
  public liability insurance in an amount satisfactory to Lender, but in no

  maintain workers' compensation insurance in accordance with Borrower's and
  EDC's usual practices.  Each insurance policy shall be endorsed in favor of
  the Lender as additional loss payee in form and substance satisfactory to
  the Lender, and provide that any proceeds payable thereunder will be paid
  to the Borrower and the Lender as their interest may appear.  Each policy
  shall provide that if such insurance is cancelled for any reason
  whatsoever, or if any substantial change is made in the coverage which
  affects the Lender, or if such insurance is allowed to lapse for nonpayment
  of premium, such cancellation, change or lapse shall not be effective as to
  the Lender until 30 days after receipt by the Lender of written notice from
  the carrier thereof.  The Borrower hereby directs all insurers under such
  policies to pay all proceeds with respect to losses of Collateral to
  the Borrower and to Lender.  With respect to occurrences giving rise to
  insurance proceeds paid with respect to losses, the Lender shall, so long
  as no uncured Default exists, release such proceeds to the Borrower after
  receipt of evidence of satisfactory repair, replacement or reconstruction
  of the assets subject to such casualty.

  all material respects with all applicable laws and duly observe all valid
  requirements of all applicable governmental authorities, including all

  or dispute any taxes, assessments or impositions in good faith, so long as
  such contest or dispute does not result in the creation or incurring of any
  liens against the Lender's Collateral and the Borrower maintains adequate
  reserves as required under GAAP for the satisfaction of the disputed tax,
  assessment or imposition.
  
            Section 6.7  Litigation.  Except as disclosed in the
  Environmental Disclosure Documents referred to in Section 5.14, promptly

  Plant Location or any of the Collateral, if:  (i) the outcome of such
  litigation, proceeding, counterclaim, or investigation would materially and
  adversely affect the Collateral or the finances or operations of Borrower
  or EDC; or (ii) such litigation, proceeding, counterclaim, or investigation

  counterclaim, or investigation as the Lender shall request.

      with respect to the DSN Plant are subject to an Environmental Lien.

  eliminate any cure period for such Default.

  during the continuance of any Event of Default:
  
                  (a)   The Lender may declare all the Obligations not
      otherwise due to be forthwith due and payable, (provided that, in the
      case of the occurrence of any Event of Default described in
      Sections 8.l(i) or (j), all the Obligations shall forthwith become
      due and payable without such declaration) whereupon the unpaid amount
      of the Obligations (including any applicable prepayment penalty)
      shall become immediately due and payable without presentment, demand,
      protest or notice of any kind, all of which are hereby expressly
      waived.  Upon such acceleration, Lender shall not be obligated to

                  (b)   Notwithstanding the foregoing in Section 8.2(a) but

      (3) days of such Notice.  The effect as an Event of Default of any
      other event described in Section 8.1 may be waived by Lender in
      writing.
  
                  (c)   In addition to all other rights provided herein or
      at law, the Lender shall have all of the rights and remedies of a
      secured party under the UCC and all of the rights and remedies
      granted under each of the Loan Documents.  At any time when an Event
      of Default has occurred and is continuing, the Lender may enter any
      premises where the Collateral is located, take physical possession of
      the Collateral or any part thereof, and maintain such possession on
      the Borrower' premises or remove any or all of the Collateral to such
      other place or places as the Lender desires in its sole discretion. 
      If the Lender exercises its right to take possession of any
      Collateral upon the occurrence and during the continuance of any
      Event of Default, the Borrower, upon the Lender's demand, will
      assemble the Collateral and at the Lender's option, make it available
      to the Lender at the Borrower' premises at which it is located or
      deliver it to such place or places as the Lender directs.  The
      Borrower hereby waives to the full extent permitted by law all rights
      to notice and hearing prior to the Lender's exercise of its rights to
      take possession of the Collateral without judicial process or to
      replevy, claim and deliver, attach or levy upon the Collateral ex
      parte.  The Lender shall not be under any obligation to marshall any
      assets in favor of the Borrower or any other party or against or in
      payment of any or all of the Obligations.
  
                  (d)   The Lender may sell and deliver any or all of the
      Collateral at public or private sale, for cash, upon credit or
      otherwise, at such prices and upon such terms as the Lender, in its
      sole discretion, deems advisable, all in accordance with the
      applicable provisions of the UCC including the standard of commercial
      reasonableness.
  
                  (e)   The requirement of reasonable notice with respect
      to a disposition of the Collateral shall be met if such notice is
      mailed both by regular and certified mail, postage prepaid to the
      Borrower at the address as set forth herein at least ten days before
      the time of the event of which notice is being given.  Subject to the
      provisions of any applicable Loan Document or law governing the
      enforcement of liens or security interests, the Lender may be the
      purchaser at any public sale, and to the extent permitted by
      applicable law, at any private sale, free from any right of
      redemption, which the Borrower also waives.
  
                  (f)   The Proceeds of any sale of any of the Collateral
      shall be applied first to all costs and expenses of sale, including
      attorneys' fees, and second to the payment (in whatever order the
      Lender elects) of all of the Obligations.  The Lender will return any
      excess Proceeds to the Borrower, subject to the claims of any other
      parties with an interest in the Collateral or the Proceeds, and the
      Borrower shall remain liable to the Lender for any deficiency.  If
      any Collateral is sold by the Lender upon credit or for future
      delivery, the Lender shall not be liable for the failure of the
      purchaser to pay for such Collateral, and in such event the Lender
      may resell the same.
  
                  (g)   The Lender may exercise any right or remedy it may
      have at law or in equity with respect to the Obligations or the
      subject matter of this Agreement.  The rights and remedies provided
      for herein are cumulative and not exclusive of any other of such
      rights and remedies or any other rights or remedies provided by law.
  
                  (h)   Upon any Default, and during any applicable cure
      period, Lender shall not be obligated to make any further advances or
      Loans to Borrower.

            Section 9.1  Survival.  All agreements, representations and
  warranties contained in this Agreement or made in writing by or on behalf
  of the Borrower in connection with the transactions contemplated hereby
  shall survive the execution and delivery of this Agreement, notwithstanding
  any investigation at any time made by the Lender.
  
            Section 9.2  Waiver of Notices.  No notice to or demand on the
  Borrower which the Lender is not required hereunder or by law to give but
  nevertheless may elect to give shall entitle the Borrower to any other or
  further notice or demand in the same, similar or other circumstances.
  
            Section 9.3  Assignment.  The provisions of this Agreement
  shall be binding upon and inure to the benefit of the respective successors
  and assigns of the parties hereto; provided, however, that no interest
  herein may be assigned by the Borrower without the prior written consent of
  the Lender.  The rights and benefits of the Lender hereunder shall, if the
  Lender so agrees, inure to any party acquiring any interest in the
  Obligations or any part thereof.  In the event of any such assignment by
  the Lender, the Borrower agrees that such assignment by the Lender shall be
  free from any set-off, counterclaim defense or other claim that any such
  Borrower may have against such assignee, without waiving any claim such
  Borrower may have against the Lender.  The terms "Lender" and "Borrower" as
  used herein shall include the respective successors and assigns of such
  parties.
  
            Section 9.4  Complete Agreement Modification.  This Agreement
  is intended by the Borrower and the Lender to be the final, complete and
  exclusive expression of the agreement between them and supersedes all prior
  agreements and understandings regarding the DSN Plant.  No modification,
  rescission, waiver, release or amendment of any provision of this Agreement
  shall be made, except by a written agreement signed by the Borrower and a
  duly authorized officer of the Lender.
  
            Section 9.5  Applicable Law.  This Agreement and the Loan
  Documents (except to the extent, if any, expressly provided to the contrary
  in any Loan Document) shall be governed by, construed, applied and enforced
  in accordance with the laws of the State of New York.
  
            Section 9.6  Indemnification.
  
                  (a)   If after receipt of any payment of all or any part
      of the Obligations, the Lender is for any reason compelled to
      surrender such payment to any person or entity, because such payment
      is determined to be void or voidable as a preference, impermissible
      setoff, or a diversion of trust funds, or for any other reason,
      Borrower's Obligations under the Note shall continue in full force
      and the Borrower shall indemnify and hold the Lender harmless for,
      the amount of such payment surrendered.  The provisions of this
      Section shall be and remain effective notwithstanding any contrary
      action which may have been taken by the Lender in reliance upon such
      payment, and any such contrary action so taken shall be without
      prejudice to the Lender's rights under this Section and shall be
      deemed to have been conditioned upon such payment having become final
      and irrevocable.  The provisions of this Section shall survive the
      termination of this Agreement.
  
                  (b)   The Borrower hereby indemnifies and holds the
      Lender, and its directors, officers, agents, employees and counsel,
      harmless from and against any and all losses, liabilities, damages,
      injuries, costs, expenses and claims of any and every kind (except
      claims brought by the Borrower against the Lender for breach of this
      Agreement of the Loan Documents) including without limitation, court
      costs and attorneys' fees imposed on or incurred by or asserted
      against any of them, whether direct, indirect or consequential
      arising out of or by reason of any litigation, investigations,
      claims, or proceedings whether based on any federal, state or local
      laws or other statutes or regulations commenced or threatened, which
      arise out of or are in any way based upon the negotiation,
      preparation, execution, delivery, enforcement, performance or
      administration of this Agreement or any other Loan Document, or any
      undertaking or proceeding relating to any of the transactions
      contemplated hereby or by any act, omission to act, event or
      transaction related or attended thereto, except this indemnification
      shall not apply to any losses, liabilities, damages, injuries, costs,
      expenses and claims caused by the gross negligence or willful
      misconduct of Lender.
  
                  (c)   The Borrower hereby indemnifies the Lender and
      agrees to hold the Lender harmless from and against any and all
      losses, liabilities, damages, injuries, costs, expenses and claims of
      any and every kind whatsoever (including, without limitation, court
      costs and attorneys' fees) which at any time or from time to time may
      be paid, incurred or suffered by, or asserted against the Lender for,
      with respect to, or as a direct result of the violation by the
      Borrower of the Environmental Laws or any laws or regulations
      relating to Hazardous Substance, treatment, storage, disposal,
      generation and transportation, air, water and noise pollution, soil
      or ground or water contamination, the handling, storage or release
      into the environment of Hazardous Substance, or with respect to, or
      as a direct or indirect result of the presence on or under, or the
      escape, seepage, leakage, spillage, discharge, emission or release
      from, properties utilized by the Borrower or EDC with respect to the
      DSN Plant in the conduct of their respective business into or upon
      any land, the atmosphere, or any watercourse, body of water or
      wetland, of any Hazardous Substance (including, without limitation,
      any losses, liabilities, damages, injuries, costs, expenses or claims
      asserted or arising under the Environmental Laws).
  
                  (d)   Without limiting any of the foregoing, if, by
      reason of any suit or proceeding of any kind, nature or description
      against the Borrower, which, in the Lender's sole discretion makes it
      advisable for the Lender to seek counsel for protection and
      preservation of its Liens, security or assets or to defend its own
      interest, such reasonable expenses and counsel fees shall be allowed
      to the Lender.  The foregoing indemnity shall survive the payment of
      the Obligations and the termination of this Agreement.  All of the
      foregoing costs and expenses shall be part of the Obligations and
      secured by the Collateral.
  
            Section 9.7  Stamp or other Tax.  Should any stamp, excise,
  sales, use or other tax, including mortgage, conveyance, deed, intangible
  or recording taxes become payable in respect of this Agreement, or any
  other Loan Document, any Obligations, or any Collateral, or any
  modification hereof or thereof, the Borrower shall pay the same (including
  interest and penalties, if any) and shall hold the Lender harmless with
  respect thereto, except for income taxes of Lender as a result thereof.
  
            Section 9.8  Captions.  The captions of the various sections of
  this Agreement have been inserted only for purposes of convenience; such
  captions are not a part of this Agreement and shall not be deemed in any
  manner to modify, explain, enlarge or restrict any provision hereof.
  
            Section 9.9  Notices.  All notices or other communications
  which are required or permitted hereunder to be given to any party shall be
  in writing and shall be deemed sufficiently delivered if delivered
  personally or by registered or certified mail, return receipt requested, or
  by nationally recognized overnight delivery service, to the address set
  forth below or to such other address as each party may designate for itself
  by like notice.  Such notice or communication shall be deemed to have been

  Any such notice, demand, or request shall be deemed given upon receipt,
  refusal of delivery or return for failure to be called for.
  
            Section 9.10  No Waiver, Lender Performance.  No course of
  dealing between the Borrower and the Lender and no delay or omission by the
  Lender in exercising any right or remedy hereunder or under any other Loan
  Document or with respect to any Obligations shall operate as a waiver
  thereof or of any other right or remedy, and no single or partial exercise
  thereof shall preclude any other or further exercise thereof or the
  exercise of any other right or remedy.  All rights and remedies of the
  Lender hereunder or under any other Loan Document shall be cumulative. 
  Upon the failure of the Borrower to perform any of its duties under this
  Agreement the Lender may, but shall not be obligated to, perform any or all
  such duties and the Borrower will upon demand reimburse the Lender for all
  reasonable costs, fees and expenses incurred in connection therewith.
  
            Section 9.11  Evidence of Obligations; Admissibility of
  Lender's Books and Records.  The Borrower agrees that the Lender's books
  and records showing the Obligations shall be admissible in any action or
  proceeding arising herefrom.
  
            Section 9.12  No Liability for Brokers.  The Borrower covenant
  and agree that the Lender shall have no liability for, and the Borrower
  hereby indemnifies and holds the Lender harmless against, any brokerage fee
  or finder's fee or other commission, or claim therefor, arising in
  connection with the transactions contemplated by this Agreement.
  
            Section 9.13  Further Assurances.  The Borrower shall, at its
  expense, do, execute and delivery such further acts and documents as the
  Lender from time to time reasonably requires for the assuring and
  confirming to the Lender of the rights created or intended to be created
  hereunder, or for carrying out the intention or facilitating the
  performance of the terms of any Loan Document or for assuring the validity,
  perfection, priority or enforceability of any Lien under any Loan Document.
  
            Section 9.14  Counterparts.  This Agreement and the other Loan
  Documents may be executed by the parties hereto and thereto in any number
  of separate counterparts, each of which when so executed and delivered
  shall be an original, but all such counterparts shall together constitute
  but one and the same instrument.
  
            Section 9.15  Notice of Breach by Lender.  Borrower agrees to
  give the Lender notice of any action or inaction by Lender or any agent or
  attorney of the Lender in connection with this Agreement, any other Loan
  Document, or the Obligations of Borrower under this Agreement or any other
  Loan Document that may be actionable against Lender or any agent or
  attorney of Lender or a defense to payment of any Obligations of Borrower
  under this Agreement or any other Loan Document, for any reason, including
  commission of a tort or violation of any contractual duty or duty implied
  by law.  Borrower agrees, to the fullest extent that it may lawfully do so,
  that unless such notice is given promptly (and in any event within fifteen
  (15) days after Borrower has knowledge, or with the exercise of reasonable
  diligence could have had knowledge, of any such action or inaction),
  Borrower shall not assert, and Borrower shall be deemed to have waived, any
  claim or defense arising therefrom to the extent that the Lender could have
  mitigated such claim or defense after receipt of such notice.
  
            Section 9.16  Time.  Time is of the essence.
  
            Section 9.17  Exhibits.  Exhibits "A", "B", "C", "D" and "E"
  attached hereto are incorporated herein by this reference.
  
            Section 9.18  Authorization to Date, Complete Blanks and
  Correct Errors.  The Borrower hereby irrevocably authorizes Lender and
  Lender's agents, representatives and employees to date, complete any blank
  spaces contained in, and to correct any errors appearing in, this
  Agreement, the other Loan Documents or in any other document relating
  hereto or thereto.
  
            Section 9.19  No Oral Agreements; Entire Agreement.  ORAL
  AGREEMENTS OR COMMITMENTS TO LOAN MONEY, EXTEND CREDIT OR TO FORBEAR FROM
  ENFORCING REPAYMENT OF A DEBT, INCLUDING PROMISES TO EXTEND OR RENEW SUCH
  DEBT, ARE NOT ENFORCEABLE.  TO PROTECT BORROWER AND LENDER FROM

  EXCLUSIVE STATEMENT OF THE AGREEMENTS BETWEEN BORROWER AND LENDER, EXCEPT

  DISTRICT OF NEW YORK, AS LENDER MAY ELECT, AND BY EXECUTION AND DELIVERY OF
  THIS AGREEMENT, BORROWER HEREBY IRREVOCABLY ACCEPTS AND SUBMITS TO, FOR
  ITSELF AND IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE
  NONEXCLUSIVE JURISDICTION OF ANY SUCH COURT, AND TO ALL PROCEEDINGS IN SUCH
  COURTS.  BORROWER IRREVOCABLY CONSENTS TO SERVICE OF ANY SUMMONS AND/OR
  LEGAL PROCESS BY REGISTERED OR CERTIFIED UNITED STATES AIR MAIL, POSTAGE
  PREPAID, TO BORROWER AT THE ADDRESS SET FORTH IN SECTION 9.9 HEREOF, SUCH
  METHOD OF SERVICE TO CONSTITUTE, IN EVERY RESPECT, SUFFICIENT AND EFFECTIVE
  SERVICE OF PROCESS IN ANY SUCH LEGAL ACTION OR PROCEEDING.  NOTHING IN THIS
  AGREEMENT SHALL AFFECT THE RIGHT TO SERVICE OF PROCESS OF PROCESS IN ANY
  OTHER MANNER PERMITTED BY LAW OR LIMIT THE RIGHT OF LENDER TO BRING
  ACTIONS, SUITS OR PROCEEDINGS IN THE COURTS OF ANY OTHER JURISDICTION. 
  BORROWER FURTHER AGREES THAT FINAL JUDGMENT AGAINST IT IN ANY SUCH LEGAL
  ACTION, SUIT OR PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN ANY
  OTHER JURISDICTION, WITHIN OR OUTSIDE THE UNITED STATES OF AMERICA, BY SUIT
  ON THE JUDGMENT, A CERTIFIED OR EXEMPLIFIED COPY OF WHICH SHALL BE
  CONCLUSIVE EVIDENCE OF THE FACT AND THE AMOUNT OF LIABILITY.
  
            Section 9.21  Waiver of Trial by Jury.  THE PARTIES TO THIS
  AGREEMENT ACKNOWLEDGE THAT JURY TRIALS OFTEN ENTAIL ADDITIONAL EXPENSES AND
  DELAYS NOT OCCASIONED BY NONJURY TRIALS.  THE PARTIES TO THIS AGREEMENT
