         A.       Initiation of each Transaction

<PAGE>

                  terms and conditions. Payment terms on the Seller's Invoices
                  will be for a period not to exceed fifty two (52) days from
                  the date of the Seller's Pro-Forma Invoice. A Final Invoice
                  will substitute each Pro-Forma Invoice within a thirty five
                  (35) day period of time from the date the Pro-Forma Invoice
                  was issued. The Final Invoice is the invoice issued by the
                  Seller to the Buyer, subsequent to the Pro-Forma Invoice which
                  indicates the total amount of Goods actually delivered to the
                  Buyer within an agreed period of time and the amount due for
                  payment on the Invoice Due Date. The aggregate amount
                  outstanding at any point in time for all Qualified
                  Receivable(s) shall not exceed One Hundred Million U.S.
                  Dollars ($100,000,000).

         B.       SCTSC Notice of Qualified Receivable(s)

                  Subject at all times to SCTSC's full discretion as to whether
                  or not it shall choose to purchase any of the Qualified
                  Receivable(s), SCTSC may accept the Seller's Transaction
                  Confirmation in the form of Appendix "C-1", annexed, if the
                  Goods and terms covering the Qualified Receivable(s) are
                  acceptable to SCTSC and if it appears to SCTSC that all
                  conditions set forth in this Agreement have been met. SCTSC
                  shall evidence any such acceptance by returning a copy of the
                  Seller's Transaction Confirmation marked "Accepted on (date)
                  by (signature)" by telefax to the Seller.

         C.       Payment to the Seller

                  Upon purchase of the Qualified Receivable(s), SCTSC shall
                  thereupon make payment to the Seller for 90% of the total
                  value of the Pro-Forma Invoice less the discount fee, handling
                  fees and any other fees or expenses incurred due to SCTSC as
                  defined in Section 2 of this Agreement and remit the
                  difference to the Seller. Approximately thirty five (35) days
                  after Seller's issuance of the Pro-Forma Invoice, the Seller
                  will issue its Final Invoice to the Buyer. This Final Invoice
                  will replace the Pro-Forma Invoice. As a condition precedent
                  for SCTSC's payment, the Seller hereby sells, assigns and
                  transfers over to SCTSC its entire title and interest in and
                  right to receive payment for each Qualified Receivable, all
                  contract rights with respect thereto and all of the Seller's
                  rights to the Goods and property represented thereby.

         D.       Payment to SCTSC

                  The Buyer will be required to remit payment for the full
                  amount of the Final Invoice, in accordance with instructions
                  provided by the Seller as per Appendix "B" and as per each
                  Final Invoice, to Standard Chartered Bank, New York Branch
                  (the "Bank"), [*] (the "Account"). The Account will be subject
                  to a Blocked Account Agreement under which the Seller
                  authorizes the Bank to remit such funds credited to this
                  Account, from time to time to Standard Chartered Bank, New
                  York Branch, [*] in order to repay SCTSC for the amount paid
                  to the Seller for the Qualified Receivable(s) purchased. The
                  balance remaining in the Account after SCTSC has been repaid
                  in full shall be remitted to the Seller.

2.       FEES AND INTEREST

         A.       Arrangement Fee

                  Upon execution of this Agreement, the Seller will pay SCTSC a
                  non-refundable arrangement fee of Twenty Five Thousand U.S.
                  Dollars ($ 25,000) to cover the initial legal, structuring and
                  set up expenses of SCTSC.

         B.       Handling Fee

                  The Seller shall pay to SCTSC a handling fee ("Handling Fee")
                  on all Qualified Receivable(s) purchased by SCTSC hereunder in
                  a flat amount of Five Hundred U.S. Dollars ($ 500), on each of
                  the Seller's Pro-Forma Invoices purchased by SCTSC. Such
                  Handling Fee shall be deducted from any payment due to the
                  Seller.

         C.       Discount Fee

                  The Seller agrees to pay SCTSC a discount fee on the
                  outstanding Qualified Receivable(s) purchased calculated at
                  the applicable LIBOR (defined below) plus a spread of seventy
                  five basis point per annum (75 b.p. p.a.) (the "Discount
                  Fee"). The Discount Fee due by the Seller to SCTSC shall be
                  calculated on the aggregate face value of the Qualified
                  Receivable(s) purchased by SCTSC from the date payment was
                  made to the Seller to the Invoice Due Date, calculated on the
                  basis of a 360 actual day year. SCTSC will deduct the
                  applicable Discount Fee from its payment due to the Seller,
                  plus any and all other fees and incidental expenses incurred
                  or anticipated by SCTSC (including legal and other fees) in
                  obtaining payment from the Buyer. The Discount Fee as
                  specified above will apply for a period not to exceed the
                  Invoice Due Date for the Qualified Receivable(s) purchased.

                  LIBOR is defined as the rate per annum at which deposits in US
                  Dollars for the period comparable to the period from the date
                  SCTSC is to make payment to the Seller to the date payment is

                  Business Days (as defined herein) prior to the date when
                  payment is made by SCTSC to the Seller, provided, however,
                  that if the Bank cannot offer SCTSC a LIBOR rate calculated as
                  set forth above, the Seller agrees that the LIBOR rate shall
                  be defined as such other rate as the Bank shall determine as
                  its cost of funds.

                  A Business Day is defined as a day on which SCTSC and
                  commercial banks are open for business in New York, New York.

         D.       Excess Costs

                  Any Qualified Receivable(s) not paid on the Invoice Due Date
                  by Buyer shall be subject to a penalty to cover any excess
                  costs incurred by SCTSC as a result of any delay in the Buyer
                  making payment by the Invoice Due Date. The Seller shall have
                  the responsibility of collecting such excess costs from the
                  Buyer as well as the ultimate responsibility for payment of
                  SCTSC's excess costs. The Seller

                                    3 of 15
<PAGE>

                  hereby assigns and transfers to SCTSC all such amounts the
                  Seller shall receive in coverage of such excess costs. The
                  Seller shall set the penalty rate for such excess costs, but
                  it shall be no less than the Bank's applicable overnight
                  Reference Rate in effect from time to time plus a margin of
                  two percent per annum (2% p.a.) and shall be based on the face
                  amount of the Final Invoice from the Invoice Due Date until
                  full repayment thereof has been received by SCTSC from the
                  Buyer.

                  "Reference Rate" is defined as the rate established from time

                  a.m. New York time.

         E.       Mis-directed Payments

                  In the event of funds being forwarded in error by the Buyer
                  directly to another account of the Seller rather than to the
                  Account, the Seller undertakes to hold these funds in trust
                  for SCTSC and to immediately remit said payment to the Bank,
                  ABA Number 026002561, for the account of SCTSC, Account No.
                  3582-088476-001, Attention: Mr. Serafin J. Cabayan. The Seller
                  will pay SCTSC a rate of interest equal to the Bank's
                  applicable overnight Reference Rate plus three percent per
                  annum (3% p.a.) based on a 360 day year and the actual number
                  of days elapsed, for the period between receipt of payment by
                  the Seller and the date such funds are received in full by
                  SCTSC.

3.       ROLE AND RESPONSIBILITY OF THE SELLER

         A.       Relationship of Parties

                  Neither the Seller nor SCTSC shall be deemed a partner, agent,

                           contractual restriction binding on or affecting the
                           Seller and that the Buyer is a party with which the
                           Seller is permitted to transact business pursuant to
                           all applicable laws, regulations and rulings of both

                           business and, in particular, to the regulations of
                           the U.S. Treasury Department's Office of Foreign
                           Assets Control;

                  (vi)     to the best of its knowledge there exist no material
                           disputes or discrepancies outstanding between the
                           Seller and the Buyer relating to prior transactions
                           (except to the extent that the Seller advises SCTSC
                           of such a dispute and SCTSC chooses in its sole
                           discretion to waive such dispute or discrepancy
                           solely for the purpose of purchasing a Qualified
                           Receivable).

                  (vii)    each of the Qualified Receivable(s) is a legal,
                           binding and assignable by the Seller and is
                           enforceable in accordance with its respective terms.

                  (viii)   each of the Qualified Receivable(s) is or will be
                           unaltered and genuine and the Seller has exclusive
                           and unencumbered title to same.

                  (ix)     each of the Qualified Receivable(s) will not have
                           been sold, assigned, transferred or encumbered by a

                           indirectly, prior to its acceptance by SCTSC and this

                           do not conflict with any agreement binding on the
                           Seller.

                  (xi)     to the best of the Seller's knowledge, the Buyer has
                           not asserted any claim, defense or right of offset to
                           payment of the Qualified Receivable(s), nor does it
                           have grounds to make such assertions. However, if the
                           Seller learns of any such claim, defense or right of
                           offset, it will promptly notify SCTSC thereof in
                           writing.

                           transport documents, pipeline tickets, receipts or
                           nominations, truck or marine bill(s) of lading, as
                           may be required by SCTSC, is or will be unaltered and
                           genuine and the Seller has exclusive and unencumbered

                           claims, losses and expenses (including, but not
                           limited to legal fees) incurred or suffered by SCTSC
                           as a result of any transaction or as a result of the
                           Seller's breach of any representation or warranty
                           contained herein or the Seller's failure to comply
                           with any of the terms or conditions contained herein.

                  (xiv)    SCTSC is granted hereby a security interest in and a
                           right of set-off with respect to all Qualified
                           Receivable(s) which have been purchased by SCTSC and
                           in all contract rights and proceeds related thereto,
                           all as security for payment and performance of all of
                           the Seller's obligations

                           Receivable(s).

                  including but not limited to claims relating to the
                  performance (or nonperformance) of the Seller, the quality of
                  the Goods supplied, the contents of any shipments and/or any
                  damage or loss (economic or physical) suffered by the Buyer or
                  any other person arising out of the Goods supplied. The Seller
                  agrees to bear the full risk of defects in or due to the
                  nonconformity of the Goods. The Seller further agrees that it
                  shall hold SCTSC harmless and indemnify SCTSC from any and all
                  claims of the Buyer or any third party relating to any product
                  liability and/or damage claim of any party or person arising
                  from the non-performance of the Seller, from defects in the
                  Goods or injury or loss arising from the Goods. The Seller
                  further acknowledges that SCTSC shall be excused from
                  performing any obligations hereunder which are prevented or
                  delayed by any occurrence not within its effective control
                  including, without limitation, destruction or damage to the
                  Goods, strikes, floods, fire, accidents, Acts of God or any
                  governmental orders or regulations; provided, however, any
                  disruption of obligations to be performed by SCTSC due to the
                  date roll-over from 1999 to 2000 and the leap-year in 2000
                  shall not be deemed to excuse SCTSC from its obligations
                  hereunder.

         D.       On each date on which any amounts fall due for payment from
                  either SCTSC or the Seller under this Agreement for any
                  transaction, the party required to make such payment shall
                  effect such payment denominated in U.S. Dollars ("Dollars")

                  such funds as may at the time be customary in the City of New
                  York for settlement in the City of New York of banking
                  transactions in Dollars) to such account in the United States
                  of the other party as such party may designate to the other in
                  writing; or, where such amount is denominated in any other
                  currency, by payment in such other currency and in immediately
                  available funds (or in such funds as may at the time be
                  customary in the city of delivery of such funds for the
                  settlement in such city of international banking transactions)
                  to such account of the other party as shall be specified by it
                  in the Transaction Confirmation.

                  set-off or counterclaim and without deduction for or on

                  limited to duties, levies, sales or value added taxes and
                  imposts now or hereafter imposed. If the Buyer is required by
                  law to make any deduction or any withholding is required to be
                  made, the Seller shall ensure that the relevant payment shall
                  be increased to the extent necessary to ensure that, after the
                  making of such deduction or withholding, SCTSC receives (free
                  from any liability in respect of any such deduction or
                  withholding) a net sum equal to the sum which would have been
                  received and so retained had no such deduction or withholding
                  been made.

                  All payments relating to the transactions contemplated by this
                  Agreement shall be made free and clear of and without
                  deduction or withholding for any present or future taxes,
                  levies, imposts or duties imposed by any governmental
                  authority in any jurisdiction or by any political subdivision
                  or taxing authority thereof or therein. If any such taxes,
                  levies, imposts or duties are required to be withheld from any
                  payments made hereunder, the amounts so payable shall be
                  increased to the extent necessary to yield to SCTSC (after
                  deduction of all such taxes, levies, imposts or duties)
                  interest or any such other amounts as specified herein.

         G.       Assignment and Delegation

                  The parties hereto may assign this Agreement and their
                  respective rights, duties and obligations hereunder solely
                  upon the written consent of the other; provided, however, that
                  SCTSC may freely assign this Agreement and its rights, duties
                  and obligations to any entity within the Standard Chartered
                  Bank Group upon notice to the Seller, provided that such
                  assignment does not result in additional costs to the Seller.
                  The parties agree that this Agreement shall inure to the
                  benefit of any successor to the parties.

         H.       Agreement not Exclusive

                  The rights to indemnification and recourse to the Seller
                  provided to SCTSC under this Agreement shall be independent
                  of, and neither subject to nor in derogation of, any other
                  rights to which SCTSC may be entitled, including, without
                  limitation, any such rights which may be assertable under the
                  General Corporation Law of New York.

         I.       Severability

                  Any provision of this Agreement which is prohibited or
                  unenforceable in any jurisdiction shall not invalidate the
                  remaining provisions hereof, which shall remain in full force
                  and effect, and any such prohibition or unenforceability in
                  any jurisdiction shall not invalidate or render unenforceable
                  such provision in any other jurisdiction.

         J.       Disclaimer of Warranty

                  SCTSC does not make and shall not be deemed to have made any
                  representation or warranty of any kind in favor of the Buyer
                  or any other person, including without limitation: any
                  representation concerning the title of SCTSC to the Goods; any
                  representation that SCTSC is a manufacturer, merchant or
                  dealer in goods; any representation or warranty, express or
                  implied, as to the

                                    11 of 15
<PAGE>

                  merchantability, compliance with specifications, design,
                  operation, freedom from patent or trademark infringement,
                  absence of latent defects or fitness for use of the Goods; or
                  any other representations, express or implied, with respect to
                  the Goods. SCTSC shall not be liable for any consequential
                  damages.

          K.      Governing Law and Jurisdiction

                  This Agreement shall be governed and construed under the laws
                  of the State of New York. Each party hereby consents to the
                  non-exclusive jurisdiction of the Federal Court in the
                  Southern District of New York or the State Courts of New York
                  with respect to any suit, action or proceeding arising out of
                  this Agreement. The Seller specifically and unconditionally
                  waives any and all right to any trial before a jury in any
                  action connected with or arising under this Agreement or under
                  any transaction as contemplated herein. The Seller agrees to
                  waive any right to seek a change of venue once an action is
                  commenced in the U.S. District Court, Southern District of New
                  York or the Supreme Court of the State of New York.

IN WITNESS WHEREOF, the Seller and SCTSC have each caused this Agreement to be

                                     TO THE
