the rights of the Collateral Agent in the Receivables.

Grantor, the Collateral Agent or any other Person, shall be paid by the Grantor.

                  SECTION 5.6. INSTRUMENTS. If any of the Receivables becomes
evidenced by an Instrument, the Grantor shall promptly notify the Collateral

              take any action which, in the reasonable opinion of the Collateral
              Agent, may be necessary or advisable in connection with any of the
              foregoing (the Contracts, together with all of the foregoing in
              this SECTION 6.1, the "CONTRACT RIGHTS");

PROVIDED, HOWEVER, that, unless an Event of Default shall have occurred and be
continuing, notwithstanding anything else herein to the contrary, the Grantor
may, subject to the terms and provisions of the U.S. Project Loan Agreement and
the Trinidad Project Loan Agreement, exclusively exercise all of its rights,
powers, privileges and remedies under the Contracts, other than the right to
receive monies due or to become due under the Contracts.

                  SECTION 6.2. FURTHER PROTECTION. Subject to the terms and
conditions of the Intercreditor Agreement, the Grantor warrants and forever
shall defend its title to the Contract Rights against the claims and demands of
any other Person, except those made pursuant to Permitted Liens, and hereby
grants the Collateral Agent full power and authority, upon the occurrence or
during the continuance of an Event of Default, to take all actions as the
Collateral Agent reasonably deems necessary or advisable to effectuate the
provisions set forth in this sentence.

                  SECTION 6.3. LIABILITIES UNDER RECEIVABLES AND CONTRACTS.
Anything herein to the contrary notwithstanding (including, without limitation,
the grant of any rights to the Collateral Agent), the Grantor shall remain
liable under this Agreement and each of the Receivables and Contracts to observe
and perform all the conditions and obligations to be observed and performed by
it thereunder and under or with respect to the Funding Company Security
Agreement Collateral, all in accordance with the terms of any agreement giving
rise to each such Receivable or Contract. Except as the parties hereto may
otherwise agree, the Collateral Agent shall not have any obligation or liability
under any Receivable (or any agreement giving rise thereto), Contract or with
respect to the Funding Company Security Agreement Collateral by reason of or
arising out of this Funding Company Security Agreement or the receipt by the
Collateral Agent of any payment relating to such Receivable or Contract pursuant
hereto, nor shall the Collateral Agent be obligated in any manner to perform any
of the obligations of the Grantor under or pursuant to any Receivable (or any
agreement giving rise thereto) or under or pursuant to any Contract, to make any
payment, to make any inquiry as to the nature or the

                                       17
<PAGE>

sufficiency of any payment received by it or as to the sufficiency of any
performance by any party under any Receivable (or any agreement giving rise
thereto) or under any Contract, to present or file any claim, to take any action
to enforce any performance or to collect the payment of any amounts which may
have been assigned to it or to which it may be entitled at any time or times.

                  SECTION 6.4. REMEDIES. Upon the occurrence of any Event of
Default, the Collateral Agent shall have the rights set forth in ARTICLE VII
hereof, and in addition may, subject to the terms of the Intercreditor Agreement
(i) enforce all remedies, rights, powers and privileges of the Grantor under any
or all of the Contracts, (ii) sell or assign any or all of the Contract Rights
which may be sold or assigned at public or private sale upon at least ten (10)
days' prior written notice and/or (iii) substitute itself or any nominee or
trustee in lieu of the Grantor as party to any of the Contracts and to notify
the obligor of any Contract Right (the Grantor hereby agreeing to deliver any
such notice at the request of the Collateral Agent) that all payments and
performance under the relevant Contract shall be made or rendered to the
Collateral Agent or such other Person as the Collateral Agent may designate.


                                   ARTICLE VII

                 REMEDIES UPON OCCURRENCE OF AN EVENT OF DEFAULT

                  SECTION 7.1. REMEDIES; OBTAINING THE FUNDING COMPANY SECURITY
AGREEMENT COLLATERAL UPON DEFAULT. (a) Subject to the terms of the Intercreditor
Agreement and the Trinidad Project Loan Agreement, upon the occurrence and
during the continuance of an Event of Default and after the expiration of any
applicable grace or cure periods, the Collateral Agent, acting pursuant to the
Intercreditor Agreement, shall be entitled to exercise all the rights and
remedies of a secured party under the Uniform Commercial Code as in effect in
any relevant jurisdiction and all rights now or hereafter existing under all
other Applicable Laws to enforce this Funding Company Security Agreement and the
Security Interest contained herein, and, in addition, subject to any Applicable
Laws then in effect, the Collateral Agent may, in addition to its other rights
and remedies hereunder, including without limitation under SECTION 7.2
(Remedies; Disposition of the Funding Company Security Agreement Collateral) and
SECTION 7.5 (Discontinuance of Proceedings) of this Funding Company Security
Agreement, and also the rights of the Collateral Agent under any of the Finance
Documents, do any of the following:

                  (i) personally, or by agents, trustees or attorneys,
immediately take possession of the Funding Company Security Agreement Collateral
or any part thereof, from the Grantor or any other Person who then has
possession of any part thereof with or without notice or process of law, and for
that purpose may enter upon the Grantor's

                                       18
<PAGE>

premises or such other Person's premises where any of the Funding Company
Security Agreement Collateral is located and remove the same and use in
connection with such removal any and all services, supplies, aids and other
facilities of the Grantor;

                  (ii) instruct the obligor or obligors of any agreement,
instrument or other obligation (including, without limitation, the Receivables
and the Contracts) constituting the Funding Company Security Agreement
Collateral to make any payment required by the terms of such instrument or
agreement directly to the Collateral Agent, PROVIDED that such agreement or
instrument permits such payment; and

                  (iii) take possession of the Funding Company Security
Agreement Collateral or any part thereof, by directing the Grantor in writing to
turn over the same to the Collateral Agent at the Site or, to the extent such
Funding Company Security Agreement Collateral may be moved, to deliver the same
to the Collateral Agent at any other place or places designated by the
Collateral Agent, in which event the Grantor shall, at its own expense, (A)
forthwith turn over the same to the Collateral Agent at one of the locations on
SCHEDULE 4.2 or at such other location as the Grantor may establish in
accordance with SECTION 4.2 (Location of Inventory and Equipment) or cause the
same to be moved to the place or places so designated by the Collateral Agent
and there delivered to the Collateral Agent, as the case may be; (B) store and
keep any Funding Company Security Agreement Collateral so turned over or
delivered to the Collateral Agent at one of the locations on SCHEDULE 4.2 or at
such other location as the Grantor may establish in accordance with SECTION 4.2
(Location of Inventory and Equipment) or at such place or places pending further
action by the Collateral Agent as provided in SECTION 7.2 (Remedies; Disposition
of the Funding Company Security Agreement Collateral) hereof; and (C) while the
Funding Company Security Agreement Collateral shall be so stored and kept,
provide such guards and maintenance services as shall be necessary to protect
the same and to preserve and maintain the Funding Company Security Agreement
Collateral in good condition.

                  (b) the Grantor's obligation to turn over or deliver the
Funding Company Security Agreement Collateral as set forth above is of the
essence of this Funding Company Security Agreement and, accordingly, upon
application to a court of equity having jurisdiction, the Collateral Agent shall
be entitled to obtain a decree requiring specific performance by the Grantor of
said obligation.

                  (c) when the Funding Company Security Agreement Collateral is
in the Collateral Agent's possession, (i) the Grantor shall pay (or reimburse
the Collateral Agent on demand for) all reasonable expenses (including the cost
of any insurance and payment of taxes or other charges and attorneys' fees of
the Collateral Agent) incurred in the custody, preservation, use or operation of
the Funding Company Security Agreement Collateral, and the obligation to
reimburse all such expenses shall be secured hereby, and

                                       19
<PAGE>

(ii) the risk of accidental loss or damage shall be on the Grantor to the extent
of any deficiency in any effective insurance coverage.

                  (d) the Grantor shall reimburse the Collateral Agent for all
its expenses in connection with the exercise of its rights hereunder, including,
without limitation, all reasonable attorneys' fees and legal expenses incurred
by the Collateral Agent. Expenses of retaking, holding, preparing for sale,
selling or the like shall include the reasonable attorneys' fees and legal
expenses of the Collateral Agent. All such expenses shall be secured hereby.

                  SECTION 7.2. REMEDIES; DISPOSITION OF THE FUNDING COMPANY
SECURITY AGREEMENT COLLATERAL. Any Funding Company Security Agreement Collateral
repossessed by the Collateral Agent under or pursuant to SECTION 7.1 (Remedies;
Obtaining the Funding Company Security Agreement Collateral upon Default) and
any other Funding Company Security Agreement Collateral, whether or not so
repossessed by the Collateral Agent, may, to the extent permitted by any
Contract terms governing such Funding Company Security Agreement Collateral and
subject to the Intercreditor Agreement, be sold, leased or otherwise disposed of
under one or more contracts or as an entirety, whether by public or private sale
and without the necessity of gathering at the place of sale; the property to be
sold, may be sold in such manner, at such time or times, at such place or places
and on such terms (whether cash or credit, and in the case of credit, without
assumption of future credit risk) as the Collateral Agent may, in compliance
with Applicable Laws, determine to be commercially reasonable. If any Funding
Company Security Agreement Collateral is sold by the Collateral Agent upon
credit or for future delivery, the Collateral Agent shall not be liable for the
failure of the purchaser to pay for the same and in such event the Collateral
Agent may resell the Funding Company Security Agreement Collateral. In no event
shall the Grantor be credited with any part of the proceeds of sale of any
Funding Company Security Agreement Collateral until cash payment thereof has
actually been received by the Collateral Agent. Any of the Funding Company
Security Agreement Collateral may be sold, leased or otherwise disposed of, or
options or contracts may be entered to do so, in the condition in which the same
existed when taken by the Collateral Agent or after any overhaul or repair which
the Collateral Agent shall determine to be commercially reasonable. Any such
disposition shall be made upon not less than ten (10) Business Days' written
notice to the Grantor specifying the time such disposition is to be made and, if
such disposition shall be a public sale, specifying the place of such sale. Any
such sale may be adjourned by announcement at the time and place fixed therefor,
and such sale may, without further notice, be made at the time and place to
which it was so adjourned. To the extent permitted by Applicable Laws, the
Collateral Agent may itself bid for and become the buyer of the Funding Company
Security Agreement Collateral or any item thereof offered for sale at a public
auction without accountability to the Grantor.

                  SECTION 7.3. WAIVER. (a) EXCEPT AS OTHERWISE PROVIDED IN THIS
FUNDING COMPANY SECURITY AGREEMENT, THE GRANTOR HEREBY WAIVES, TO THE EXTENT
PERMITTED BY APPLICABLE LAW, NOTICE OR JUDICIAL HEARING IN CONNECTION WITH THE
COLLATERAL AGENT'S TAKING POSSESSION OR THE FUNDING COMPANY SECURITY AGREEMENT
COLLATERAL AGENT'S DISPOSITION OF ANY OF THE COLLATERAL IN ACCORDANCE WITH THIS
AGREEMENT, INCLUDING, WITHOUT LIMITATION, ANY AND ALL PRIOR NOTICE AND HEARING
FOR ANY PREJUDGMENT REMEDY OR REMEDIES AND ANY SUCH RIGHT WHICH THE GRANTOR
WOULD OTHERWISE HAVE UNDER THE CONSTITUTION OR ANY STATUTE OF THE UNITED STATES
OR OF ANY STATE, AND THE GRANTOR HEREBY FURTHER WAIVES TO THE EXTENT PERMITTED
BY APPLICABLE LAWS:

                     (i) all damages occasioned by such taking of possession
                  except any damages which are finally judicially determined to
                  have been the direct result of the Collateral Agent's gross
                  negligence or wilful misconduct;

                     (ii) all other requirements as to the time, place and terms
                  of sale or other requirements with respect to the enforcement
                  of the Collateral Agent's rights hereunder;

                     (iii) demand of performance or other demand, notice of
                  intent to demand or accelerate, notice of acceleration,
                  presentment, protest, advertisement or notice of any kind to
                  or upon the Grantor or any other Person; and

                     (iv) all rights of redemption, appraisement, valuation,
                  stay, extension or moratorium now or hereafter in force under
                  any Applicable Laws in order to prevent or delay the
                  enforcement of this Funding Company Security Agreement or the
                  absolute sale of the Funding Company Security Agreement
                  Collateral or any portion thereof, and the Grantor, insofar as
                  it may now or hereafter lawfully do so, hereby waives the
                  benefit of such Applicable Laws.

                  (b) Without limiting the generality of the foregoing, the
Grantor hereby: (i) authorizes the Collateral Agent, in its sole discretion and
without notice to or demand upon the Grantor and without otherwise affecting the
obligations of the Grantor hereunder from time to time, to take and hold other
collateral granted to it by any other Person (in addition to the Funding Company
Security Agreement Collateral) for payment of any Obligations, or any part
thereof, and to exchange, enforce or release such other collateral or any part
thereof, and to accept and hold any endorsement or guarantee of payment of

                                       21
<PAGE>

the Obligations or any part thereof, and to release or substitute any endorser
or guarantor or any other Person granting security for or in any way obligated
upon any Obligations, or any part thereof; and (ii) waives and releases any and
all right to require the Collateral Agent to collect any of the Obligations from
any specific item or items of Funding Company Security Agreement Collateral or
from any other party liable as guarantor or in any other manner in respect of
any of the Obligations or from any collateral (other than the Funding Company
Security Agreement Collateral) for any of the Obligations.

                  (c) Any sale of, or the grant of options to purchase, or any
other realization upon, any Funding Company Security Agreement Collateral shall,
provided that it is done in accordance with Applicable Laws and this Funding
Company Security Agreement, operate to divest all right, title, interest, claim
and demand, either at law or in equity, of the Grantor therein and thereto, and
shall be a perpetual bar both at law and in equity against the Grantor and
against any and all Persons claiming or attempting to claim the Funding Company
Security Agreement Collateral so sold, optioned or realized upon, or any part
thereof, from, through and under the Grantor.

                  SECTION 7.4. NO WAIVER; REMEDIES CUMULATIVE. No failure or
delay on the part of the Collateral Agent in exercising any right, remedy, power
or privilege hereunder and no course of dealing between the Grantor and the
Collateral Agent shall operate as a waiver thereof; nor shall any single or
partial exercise of any right, power or privilege hereunder preclude any other
or further exercise thereof or the exercise of any other right, remedy, power or
privilege. A waiver by the Collateral Agent of any right or remedy hereunder on
any one occasion shall not be construed as a bar to any right or remedy which
the Collateral Agent would otherwise have on any future occasion. The rights and
remedies herein expressly provided are cumulative and may be exercised singly or
concurrently and as often and in such order as the Collateral Agent deems
expedient and are not exclusive of any rights or remedies which the Collateral
Agent would otherwise have whether by agreement or now or hereafter existing
under Applicable Laws. No notice to or demand on the Grantor in any case shall
entitle the Grantor to any other or further notice or demand in similar or other
circumstances or constitute a waiver of the rights of the Collateral Agent to
any other or future action in any circumstances without notice or demand.

                  SECTION 7.5. DISCONTINUANCE OF PROCEEDINGS. In case the
Collateral Agent, on behalf of the Secured Parties, shall have instituted any
proceeding to enforce any right, power or remedy under this Funding Company
Security Agreement by foreclosure, sale, entry or otherwise, and such proceeding
shall have been discontinued or abandoned for any reason or shall have been
determined adversely to the Collateral Agent, then, in every such case, subject
to the

                                       22
<PAGE>

terms of any final non-appealable judgment rendered in any such proceeding, the
Grantor, the Collateral Agent and any other holder of any of the Obligations
shall be restored to their former positions and rights hereunder with respect to
the Funding Company Security Agreement Collateral, subject to the Security
Interest created under this Funding Company Security Agreement, and all rights,
remedies and powers of the Collateral Agent shall continue as if no such
proceeding had been instituted.

                  SECTION 7.6. APPLICATION OF PROCEEDS; GRANTOR LIABLE FOR
DEFICIENCY. The Collateral Agent shall apply any proceeds from time to time held
by it and the net proceeds of any collection, recovery, receipt, appropriation,
realization or sale with respect to the Funding Company Security Agreement
Collateral in accordance with the Intercreditor Agreement. Any surplus remaining
after payment in full of all of the Obligations shall be paid over to the
Grantor or to whomever may be entitled to receive such surplus. The Grantor
shall be liable for any deficiency remaining after any application of funds
pursuant hereto.

effective without the prior written consent of the Collateral Agent, acting
pursuant to SECTION 2.1 of the Intercreditor Agreement, and none of the Funding

Termination Date.

or released.

                  SECTION 8.8. REINSTATEMENT. This Funding Company Security
Agreement shall continue to be effective or be reinstated, as the case may be,

reorganization of the Grantor or upon the appointment of any

                                       24
<PAGE>

intervenor or conservator of, or trustee or similar official for, the Grantor or
any substantial part of its assets, or upon the entry of an order by a
bankruptcy court avoiding payment of such amount, or otherwise, all as though
such payments had not been made.

                  SECTION 8.9. COUNTERPARTS. This Funding Company Security
Agreement may be executed in any number of counterparts, all of which, taken
together, shall constitute one and the same instrument and any of the parties
hereto may execute this Funding Company Security Agreement by signing any such
counterpart.

                  SECTION 8.10. GOVERNING LAW; SUBMISSION TO JURISDICTION. (i)
This Funding Company Security Agreement is a contract made under the laws of the
State of New York of the United States and shall for all purposes be governed by
and construed in accordance with the laws of such State without regard to the
conflict of law rules thereof (other than Section 5-1401 of the New York General
Obligations Law).

              (ii) Any legal action or proceeding against the Grantor with
respect to this Funding Company Security Agreement may be brought in the courts
of the State of New York in the County of New York or of the United States for
the Southern District of New York and, by execution and delivery of this
Agreement, the Grantor hereby irrevocably submits and accepts for itself and in
respect of its property, generally and unconditionally, the jurisdiction of the
aforesaid courts. The Grantor agrees that a judgment, after exhaustion of all
available appeals, in any such action or proceeding shall be conclusive and
binding upon the Grantor, and may be enforced in any other jurisdiction by a
suit upon such judgment, a certified copy of which shall be conclusive evidence
of the judgment. The Grantor hereby irrevocably designates, appoints and
empowers Corporation Service Company with offices on the date hereof at 375
Hudson Street, New York, New York 10014-3686, as its designee, appointee and
agent to receive, accept and acknowledge for and on its behalf, and in respect
of its property, service of any and all legal process, summons, notices and
documents which may be served in any such action or proceeding. If for any
reason such designee, appointee and agent shall cease to be available to act as
such, the Grantor agrees to designate a new designee, appointee and agent in New
York City on the terms and for the purposes of this provision satisfactory to
the Collateral Agent. The Grantor further irrevocably consents to the service of
process out of any of the aforementioned courts in any such action or proceeding
by the mailing of copies thereof by registered or certified mail, postage
prepaid, to the Grantor at its address referred to in SECTION 8.1 (Notices),
such service to become effective thirty (30) days after such mailing. Nothing
herein shall affect the right of the Collateral Agent to serve process in any
other manner permitted by law or to commence legal proceedings or otherwise
proceed against the Grantor in any other jurisdiction.

              (iii) The Grantor hereby irrevocably waives any objection which it
may now or hereafter have to the laying of venue of any of the aforesaid actions
or proceedings arising out of or in connection with this Funding Company
Security Agreement brought in the

                                       25
<PAGE>

courts referred to in clause (ii) above and hereby further irrevocably waives
and agrees not to plead or claim in any such court that any such action or
proceeding brought in any such court has been brought in an inconvenient forum.

              (iv) WITH REGARD TO THIS FUNDING COMPANY SECURITY AGREEMENT, THE
PARTIES HERETO HEREBY WAIVE THE RIGHT TO A TRIAL BY JURY.

                  SECTION 8.11. CONFLICT WITH INTERCREDITOR AGREEMENT. In case
of a conflict between any provision of this Funding Company Security Agreement
and any provision of the Intercreditor Agreement, the provisions of the
Intercreditor Agreement shall control. No such conflict shall be deemed to exist
merely because this Funding Company Security Agreement imposes greater
obligations on the Grantor than the Intercreditor Agreement.

                  SECTION 8.12. ENTIRE AGREEMENT. This Funding Company Security
Agreement, together with any other agreement executed in connection herewith, is
intended by the parties as a final expression of their agreement as to the

the terms and conditions thereof.

                  SECTION 8.13. COLLATERAL AGENT. The rights, duties, benefits,
privileges and protections provided to the Collateral Agent in accordance with
the terms of the Intercreditor Agreement or the Indenture, as applicable, are
expressly incorporated herein by reference thereto.

                  IN WITNESS WHEREOF, the parties hereto have caused this
Funding Company Security Agreement to be duly executed and delivered as a deed
by their duly authorized officers as of the date first above written.
