     Liens, contraventions, violations or conflicts which could not reasonably

                                       2
<PAGE>

          (e) This Agreement has been duly executed and delivered by Funding
     Company and constitutes the legal, valid and binding obligation of Funding
     Company, enforceable against Funding Company in accordance with its terms

     insolvency, fraudulent conveyance, reorganization, moratorium and other
     similar laws of general applicability affecting the enforcement of
     creditors' rights generally and (ii) is subject to applicable general
     principles of equity and the effect of public policy (regardless of whether
     enforceability is considered in a proceeding in law or equity).

         (f) Funding Company is the sole beneficial owner of the U.S. Project
     Note Collateral and no Lien exists or will exist upon the U.S. Project Note
     Collateral at any time (and no right or option to acquire the same exists

     security interest created by this Agreement constitutes, upon delivery of
     the U.S. Project Note Collateral to, and holding by, the Collateral Agent
     for the benefit of itself and the other Secured Parties, a first priority
     perfected pledge and security interest in and to all of the U.S. Project
     Note Collateral.

     Section 3. COLLATERAL. As collateral security for the prompt payment in
full and performance when due (whether at stated maturity, by acceleration or
otherwise) of any and all of the Secured Obligations now existing or hereafter
arising, and howsoever evidenced, Funding Company hereby pledges, assigns,
hypothecates, transfers, delivers and grants to the Collateral Agent for the
benefit of the Secured Parties, a Lien on and security interest in all of
Funding Company's rights, title and interests in and to the following property,
whether now existing or hereafter coming into existence (all being collectively
referred to herein as the "U.S. PROJECT NOTE COLLATERAL"):

         (a) the U.S. Project Note, including without limitation (i) all rights
     of Funding Company to receive moneys due and to become due under or
     pursuant to the U.S. Project Note, (ii) all rights of Funding Company to
     receive proceeds of insurance, payment and/or performance bond, indemnity,
     warranty or guaranty with respect to the U.S. Project Note, (iii) all
     claims of Funding Company for damages arising out of or for breach of or
     default under the U.S. Project Note and (iv) any security interest in the
     Depository Accounts granted to Funding Company by the U.S. Guarantors to
     secure payments due under the U.S. Project Note; and

         (b) to the extent not included in the foregoing, all proceeds of and to
     any of the property of Funding Company described in the preceding clause
     (a) and, to the extent related to any property described in said clause or
     such proceeds, all books, correspondence, credit files, invoices and other
     papers.


                                       3
<PAGE>

Notwithstanding anything herein to the contrary, for purposes of this Agreement,
Funding Company agrees that it shall not be considered a Secured Party hereunder
and the amounts owed to it by the U.S. Guarantors shall not be considered
Secured Obligations.

     Section 4. FURTHER ASSURANCES; REMEDIES. In furtherance of the grant of the
pledge and security interest pursuant to SECTION 3 hereof, Funding Company
hereby agrees with the Collateral Agent and each other Secured Party as follows:

     4.1 DELIVERY AND OTHER PERFECTION.  Funding Company shall:

         (a) if any of the property required to be pledged or assigned by
     Funding Company under SECTION 3 hereof is received by Funding Company
     forthwith either (i) transfer and deliver to the Collateral Agent such
     property so received by Funding Company (endorsed in blank and accompanied
     by such instruments of assignment and transfer as the Collateral Agent may
     reasonably request) all of which thereafter shall be held by the Collateral
     Agent, pursuant to the terms of this Agreement and the Intercreditor
     Agreement, as part of the U.S. Project Note Collateral or (ii) take such
     other action as the Collateral Agent may reasonably request as is necessary
     or appropriate to duly record the Lien created hereunder in such property
     in said SECTION 3 hereof;

         (b) give, execute, deliver, file and/or record any financing statement,
     notice, instrument, document, agreement or other papers that may be
     necessary or desirable to create, preserve or validate the pledge and
     security interest granted pursuant hereto or to enable the Collateral Agent
     to exercise and enforce its rights hereunder with respect to such pledge
     and security interest, including, without limitation, causing any or all of
     the U.S. Project Note Collateral to be transferred of record into the name
     of the Collateral Agent or its nominee (and the Collateral Agent agrees
     that if any U.S. Project Note Collateral is transferred into its name or
     the name of its nominee, the Collateral Agent will thereafter promptly give
     to Funding Company, copies of any notices and communications received by it
     with respect to the U.S. Project Note Collateral).

         (c) keep full and accurate books and records relating to the U.S.
     Project Note Collateral, and stamp or otherwise mark such books and records
     in such manner as the Collateral Agent may reasonably require in order to
     reflect the security interests granted by this Agreement; and

         (d) permit representatives of the Collateral Agent, at the expense of
     Funding Company and upon five (5) days written notice, at any time during
     normal business hours to inspect and make abstracts from its books and
     records pertaining to the U.S. Project Note Collateral.


                                       4
<PAGE>


     4.2 OTHER FINANCING STATEMENTS AND LIENS.

         (a) Other than with respect to Permitted Liens, Funding Company shall
     not file or suffer to be on file, or authorize or permit to be filed or to
     be on file, in any jurisdiction, any financing statement or like instrument
     with respect to the U.S. Project Note Collateral in which the Collateral
     Agent is not named as the sole secured party for the benefit of itself and
     the other Secured Parties.

         (b) Funding Company hereby authorizes the Collateral Agent to file one
     or more financing statements, and amendments thereto, relating to all or
     any part of the U.S. Project Note Collateral without the signature of
     Funding Company where permitted by Applicable Law if necessary or
     appropriate to perfect the Liens granted hereunder. Copies of such
     statement or amendment thereto shall promptly be delivered to Funding
     Company.

     4.3 PRESERVATION OF RIGHTS. The Collateral Agent shall not be required to
take steps necessary to preserve any rights against prior parties to any of the
U.S. Project Note Collateral, including, without limitation, making
determinations as to whether, when and how to perfect a security interest in the
U.S. Project Note Collateral.

     4.4 U.S. PROJECT NOTE COLLATERAL.

         (a) So long as no Trigger Event shall have occurred and be continuing,
     Funding Company shall have the right to exercise all rights and powers of
     ownership pertaining to the U.S. Project Note Collateral; PROVIDED that
     Funding Company agrees that it will not exercise such rights and powers in
     any manner that is inconsistent with the terms of this Agreement or any
     other Finance Document and the Collateral Agent shall execute and deliver
     to Funding Company or cause to be executed and delivered to Funding Company
     all such powers of attorney and other orders, and all such instruments,
     without recourse, as Funding Company may reasonably request for the purpose
     of enabling Funding Company to exercise the rights and powers that it is
     entitled to exercise pursuant to this SECTION 4.4(a).

         (b) If any Trigger Event shall have occurred and be continuing, then so
     long as such Trigger Event shall continue, all payments and other
     distributions in respect of the U.S. Project Note Collateral shall be paid
     directly to the Collateral Agent and retained by it as part of the U.S.
     Project Note Collateral, subject to the terms of this Agreement, and if the
     Collateral Agent shall so request in writing, Funding Company agrees to
     execute and deliver to the Collateral Agent appropriate additional orders
     and documents to that end; PROVIDED that if such Trigger Event is cured,
     any such payment or distribution theretofore paid to the Collateral Agent
     shall, upon request of Funding Company (except to the extent


                                       5
<PAGE>

     theretofore applied to the Secured Obligations), be returned by the
     Collateral Agent to Funding Company.

         (c) After the occurrence and during the continuance of any Trigger
     Event, Funding Company shall not take any action to revoke, amend or
     supersede any instructions delivered by the Collateral Agent on behalf of
     Funding Company to the Guarantors or the Bond Trustee directing the
     Guarantors or the Bond Trustee to make payments or other distributions
     payable to Funding Company directly to the Collateral Agent.

         (d) The exercise by the Collateral Agent of its rights hereunder shall
     not constitute an election by the Collateral Agent to retain the U.S.
     Project Note Collateral in satisfaction of the Secured Obligations or
     affect the Collateral Agent's rights to any other collateral or against
     Funding Company or any other Person.

     4.5 EVENTS OF DEFAULT. Subject to the Intercreditor Agreement, upon the
occurrence and during the continuance of a Trigger Event.

         (a) the Collateral Agent shall have all of the rights and remedies with
     respect to the U.S. Project Note Collateral of a secured party under the
     Uniform Commercial Code (whether or not said code is in effect in the
     jurisdiction where the rights and remedies are asserted) and such
     additional rights and remedies to which a secured party is entitled under
     the Laws in effect in any jurisdiction where any rights and remedies
     hereunder may be asserted including, without limitation, the right, to the
     maximum extent permitted by Applicable Law, to exercise all voting,
     consensual and other powers of ownership pertaining to the U.S. Project
     Note Collateral as if the Collateral Agent were the sole and absolute owner
     thereof (and Funding Company agrees to take all such action as may be
     appropriate to give effect to such right);

         (b) the Collateral Agent in its sole discretion may, in its name or in
     the name of Funding Company or otherwise, demand, sue for, collect or
     receive any money or property at any time payable or receivable on account
     of or in exchange for any of the U.S. Project Note Collateral, but shall be
     under no obligation to do so; and

         (c) the Collateral Agent may, upon ten (10) Business Days prior written
     notice to Funding Company of the time and place, with respect to the U.S.
     Project Note Collateral or any part thereof, sell, lease, assign or
     otherwise dispose of all or any part of such U.S. Project Note Collateral,
     at such place or places as the Collateral Agent reasonably deems best, and
     for cash or for credit or for future delivery (without thereby assuming any
     credit risk), at public or private sale, without demand of performance or
     notice of intention to effect any such disposition

                                       6
<PAGE>

     or of the time or place thereof (except such notice as is required above or
     by Applicable Law and cannot be waived), and the Collateral Agent or anyone
     else may be the purchaser, lessee, assignee or recipient of any or all of
     the U.S. Project Note Collateral so disposed of at any public sale (or, to
     the extent permitted by Applicable Law, at any private sale) and thereafter
     hold the same absolutely, free from any claim or right of whatsoever kind,
     including any right of equity or redemption (statutory or otherwise), of
     Funding Company, any such demand, notice and right or equity being hereby
     expressly waived and released. The Collateral Agent may, without notice or
     publication, adjourn any public or private sale or cause the same to be
     adjourned from time to time by announcement at the time and place fixed for
     the sale, and such sale may be made at any time or place to which the sale
     may be so adjourned. The proceeds of each collection, sale or other
     disposition under this SECTION 4.5 shall be applied in accordance with
     SECTION 4.9 hereof.

Funding Company recognizes that, by reason of certain prohibitions contained in
the Securities Act and applicable state securities laws, the Collateral Agent
may be compelled, with respect to any sale of all or any part of the U.S.
Project Note Collateral, to limit purchasers to those who will agree, among
other things, to acquire the U.S. Project Note Collateral for their own account,
for investment purposes only and not with a view to the distribution or resale
thereof. Funding Company acknowledges that any such private sales may be at
prices and on terms less favorable to the Collateral Agent than those obtainable
by the Collateral Agent through a public sale without such restrictions, and,
notwithstanding such circumstances, agrees that any such private sale shall be
deemed to have been made in a commercially reasonable manner and that the
Collateral Agent shall have no obligation to engage in public sales and no
obligation to delay the sale of any of the U.S. Project Note Collateral for the
period of time necessary for Funding Company or any issuer thereof to register
it for public sale.

     4.6 DEFICIENCY. If the proceeds of sale, collection or other realization of
or upon the U.S. Project Note Collateral pursuant to SECTION 4.5 hereof are
insufficient to cover the reasonable costs and expenses of such realization and
the payment in full of the Secured Obligations, Funding Company shall, subject
to SECTION 4.18, remain liable for any deficiency.

     4.7 REMOVALS. Without at least thirty (30) days' prior written notice to
the Collateral Agent, Funding Company shall not (i) maintain any of its books
and records with respect to the U.S. Project Note Collateral at any office or
maintain its principal place of business at any place other than at the address
indicated in SECTION 5.2 hereof or (ii) change its corporate name, or the name
under which it does business, from the name shown on the signature pages hereto.

                                       7
<PAGE>

     4.8 PRIVATE SALE. The Collateral Agent shall not incur any liability as a
result of the sale of the U.S. Project Note Collateral, or any part thereof, at
any private sale pursuant to SECTION 4.5 hereof conducted in a commercially
reasonable manner. To the extent permitted by Applicable Law, Funding Company
hereby waives any claims against the Collateral Agent arising by reason of the
fact that the price at which the U.S. Project Note Collateral may have been sold
at a private sale was less than the price that might have been obtained at a
public sale or was less than the aggregate amount of the Secured Obligations
even if the Collateral Agent accepts the first offer received and does not offer
such U.S. Project Note Collateral to more than one offeree.

     4.9 APPLICATION OF PROCEEDS. Except as otherwise expressly provided in the
Intercreditor Agreement, the proceeds of any collection, sale or other
realization of all or any part of the U.S. Project Note Collateral pursuant
hereto, and any other cash at the time held by the Collateral Agent under this
SECTION 4, shall, after the occurrence and during the continuance of a Trigger
Event, be applied by the Collateral Agent in accordance with SECTION 4.3 of the
Intercreditor Agreement.

     As used in this SECTION 4, "PROCEEDS" of U.S. Project Note Collateral shall
mean cash, securities and other property realized in respect of, and
distributions in-kind of, U.S. Project Note Collateral, including any thereof
received under any reorganization, liquidation or adjustment of debt of Funding
Company, or any issuer or obligor on any of the U.S. Project Note Collateral.

     4.10 ATTORNEY-IN-FACT. Without limiting any rights or powers granted by
this Agreement to the Collateral Agent while no Event of Default has occurred
and is continuing, upon the occurrence and during the continuance of any Event
of Default, the Collateral Agent is hereby appointed the attorney-in-fact of
Funding Company for the purpose of carrying out the provisions of this SECTION 4
and taking any action and executing any instruments that the Collateral Agent
may deem necessary or advisable to accomplish the purposes hereof, which
appointment as attorney-in-fact is irrevocable and coupled with an interest.
Without limiting the generality of the foregoing, so long as the Collateral
Agent shall be entitled under this SECTION 4 to make collections in respect of
the U.S. Project Note Collateral, the Collateral Agent shall have the right and
power (subject to the Intercreditor Agreement and Depositary Agreements) to
receive, endorse and collect all instruments made payable to the order of
Funding Company representing any dividend, payment or other distribution in
respect of the U.S. Project Note Collateral or any part thereof and to give full
discharge for the same.

     4.11 PERFECTION. Prior to or concurrently with the execution and delivery
of this Agreement, Funding Company shall deliver to the Collateral Agent the
U.S. Project Note accompanied by undated bond powers duly executed in blank.


                                       8
<PAGE>


     4.12 SECURITY INTEREST ABSOLUTE. All the rights of the Collateral Agent
hereunder and the Security Interest and all obligations of Funding Company
hereunder shall be absolute and unconditional irrespective of:

         (a) any lack of validity or enforceability of any of the Transaction
     Documents or any other agreement or instrument relating thereto;

         (b) any change in the time, manner or place of payment of, or in any
     other term of, all or any of the Secured Obligations, or any other
     amendment or waiver or any consent to any departure from any of the
     Transaction Documents;

         (c) any exchange or release of any U.S. Project Note Collateral or any
     other collateral, or the non-perfection of any Security Interest, or any

provisions hereof shall remain in full force and effect in such jurisdiction and
shall be liberally construed in favor of the Collateral Agent in order to carry
out the intentions of the parties hereto as nearly as may be possible and (ii)
