                                SECURITY INTEREST

         Section 1.01 Grant of Security Interest.

         To secure the payment, observance and performance of the Secured
Obligations, the Pledgor hereby mortgages, pledges and assigns the Collateral to
the Secured Party, and grants to the Secured Party a continuing security
interest in, and a continuing lien upon, the Collateral.

         Section 1.02 Validity and Priority of Security Interest.

         The Pledgor agrees that (a) the Security Interest shall at all times be
valid, perfected and enforceable against the Pledgor and all third parties, in
accordance with the terms hereof, as security for the Secured Obligations, and
(b) the Collateral shall not at any time be subject to any Lien, other than a
Permitted Lien, that is prior to, on a parity with or junior to such Security
Interest, except that, unless a Termination Event exists, this Section 1.02
shall not require the continuation of the perfection of the Security Interest in
Ordinary Distributions that the Pledgor shall, and does, cause the Depositary
Agent to receive and retain pursuant to Section 1.06(a).

         Section 1.03 Maintenance of Status of Security Interest, Collateral and
Rights.

                  (a) Required Action.

                  The Pledgor shall take all actions, including the action
specified on Schedule 1.03, that may be necessary or desirable, or that the
Secured Party may request, so as at all times (i) to maintain the validity,
perfection, enforceability and priority of the Security Interest in the
Collateral in conformity with the requirements of Section 1.02, (ii) to protect
and preserve the Collateral and (iii) to protect and preserve, and to enable the
exercise or enforcement of, the rights of the Secured Party therein and
hereunder and under the other Collateral Documents.

                  (b) Authorized Action.

                  The Secured Party is hereby authorized to file one or more
financing or continuation statements or amendments thereto without the signature
of or in the name of the Pledgor (and the Secured Party shall give notice to the
Pledgor promptly after taking such actions; provided that



                                       1
   7
failure to give such notice shall not affect any rights or remedies hereunder).
A carbon, photographic or other reproduction of this Agreement or of any
financing statement filed in connection with this Agreement shall be sufficient
as a financing statement.

         Section 1.04 Evidence of Status of Security Interest.

         The Pledgor shall from time to time, upon the reasonable request of the
Secured Party, deliver to the Secured Party (a) such file search reports from
such Uniform Commercial Code and other filing and recording offices and (b) such
opinions of counsel relating to the Collateral, the attachment and perfection of
the Security Interest and otherwise to this Agreement, as the Secured Party may
request.

         Section 1.05 Pledgor Remains Obligated; Secured Party Not Obligated.

         The grant by the Pledgor to the Secured Party of the Security Interest
shall not (a) relieve the Pledgor of any Liability to any Person under or in
respect of any of the Collateral or (b) impose on the Secured Party any such
Liability or any Liability for any act or omission on the part of the Pledgor
relative thereto.

         Section 1.06 Pledgor's Limited Rights to Proceeds and Other Collateral.

         (a) The Pledgor shall, unless a Termination Event is continuing, cause
the Depository Agent to receive, and unless a Termination Event is continuing,
retain (A) all Account Proceeds and Ordinary Distributions and (B) proceeds of
insurance required to be maintained pursuant to Section 2.04 that aggregate less
than $1,000,000, but only to the extent such insurance proceeds are to be
applied to restore or replace the property damaged. Proceeds of insurance,
required to be maintained pursuant to Section 2.04, that aggregate at least
$1,000,000, shall be held by the Secured Party as Collateral and, unless a
Termination Event is continuing, shall be paid over to the Pledgor from time to
time to be applied to restore or replace property damaged. Any balance of such
proceeds of insurance not used to restore or replace the property damaged shall
be held by the Secured Party as Collateral. Unless an Event of Default is
continuing all instruments, chattel paper, securities, letters of credit and
documents that are Collateral shall be made available to the Pledgor upon
request for purposes of presentation, collection or renewal.

         (b) Subject to the Pledgor's rights under Section 1.06(a) and, prior to
a Termination Event, the rights of the Depository Agent under the Depositary
Agreement, the Secured Party shall be entitled to receive and retain all
proceeds of Collateral, including Extraordinary Distributions. Subject to its
rights under Section 1.06(a), the Pledgor shall cause the Depositary to receive
and hold all proceeds of Collateral in trust for the Secured Party, not
commingle the same with other funds or property and, immediately deliver the
same or cause the same to be delivered in the exact form received, together with
any necessary endorsements, to the Secured Party.

                                                                    May 11, 1999

Morgan Stanley & Co. Incorporated
Credit Suisse First Boston Corporation
CIBC World Markets Corp.
c/o Morgan Stanley & Co. Incorporated
1585 Broadway
New York, NY 10036

Dear Sirs and Mesdames:

      AES Eastern Energy, L.P., a Delaware limited partnership (the "Company"),
proposes to issue and sell jointly and severally to Morgan Stanley & Co.
Incorporated, Credit Suisse First Boston Corporation and CIBC World Markets
Corp. (collectively, the "Initial Purchasers"), on the terms set forth in a
purchase agreement of even date herewith (the "Purchase Agreement"),
$282,000,000 aggregate principal amount of Pass Through Certificates, Series
1999-A and $268,000,000 aggregate principal amount of Pass Through Certificates,
Series 1999-B (collectively, the "Certificates"). The Certificates will be
issued pursuant to two Pass Through Trust Agreements, each dated as of May 1,
1999 (the "Pass Through Trust Agreements") between the Company and Bankers Trust
Company, a New York banking corporation, as Pass Through Trustee (the
"Trustee").

      As an inducement to the Initial Purchasers to enter into the Purchase
Agreement and in satisfaction of a condition to the Initial Purchasers'
obligations thereunder, the Company agrees with the Initial Purchasers, for the
benefit of the registered holders of the Certificates (including, without
limitation, the Initial Purchasers) and the Exchange Certificates (as defined
below) (collectively, the "Holders"), as follows:

            Registered Exchange Offer.

      The Company shall prepare and file with the Securities and Exchange
Commission (the "Commission") a registration statement (the "Exchange Offer
Registration Statement") on an appropriate form under the Securities Act of
1933, as amended (the "Securities Act"), with respect to an offer (the
"Registered Exchange Offer") to the Holders of Transfer Restricted Certificates
(as defined in Section 6(d) hereof), who are not prohibited by any law or policy
of the Commission from participating in the Registered Exchange Offer, to issue
and deliver to such Holders, in exchange for the Certificates of each series, a
like aggregate principal amount of pass through trust certificates (the
"Exchange Certificates") of the Company issued under the Pass Through Trust
Agreements and identical in all material respects to the Certificates of that
series and that will be registered under the Securities Act. The Company shall
use its best efforts to cause the Exchange Offer Registration Statement to
become effective under the Securities Act within 150 days after the date of
original issue of the Certificates and shall keep the Exchange


   43


Offer Registration Statement effective for not less than 30 days (or longer, if
required by applicable law) after the date on which notice of the Registered
Exchange Offer is mailed to the Holders (that period being called the "Exchange
Offer Registration Period").

      If the Company effects the Registered Exchange Offer, the Company will be
entitled to close the Registered Exchange Offer at the close of business on the
30th day after the commencement thereof if the Company has accepted all the
Certificates validly tendered by such 30th day in accordance with the terms of
the Registered Exchange Offer.

      Following the declaration of the effectiveness of the Exchange Offer
Registration Statement, the Company shall promptly commence the Registered
Exchange Offer, it being the objective of the Registered Exchange Offer to
enable each Holder of Transfer Restricted Certificates electing to exchange
those Transfer Restricted Certificates for Exchange Certificates (assuming that
Holder is not an affiliate of the Company within the meaning of the Securities
Act, acquires the Exchange Certificates in the ordinary course of that Holder's
business and has no arrangement with any person to participate in the
distribution of the Exchange Certificates, and is not prohibited by any law or
policy of the Commission from participating in the Registered Exchange Offer) to
trade those Exchange Certificates from and after their receipt without any
limitations or restrictions under the Securities Act and without material
restrictions under the securities laws of the several states of the United
States. In connection with the Registered Exchange Offer, the Company shall use
its best efforts to consummate the Registered Exchange Offer and shall comply
with the applicable requirements of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), and other applicable laws and regulations in
connection with the Registered Exchange Offer; provided, however, that if there
are fewer than 300 holders of record of the Certificates at the beginning of the
calendar year 2000, the Company currently contemplates suspending its Exchange
Act reporting obligations early in calendar year 2000 (if such condition is not
met at the beginning of calendar year 2000, the Company would suspend its
reporting obligations at the beginning of the first year in which such condition
is met).

      The Company acknowledges that, pursuant to current interpretations by the
Commission's staff of Section 5 of the Securities Act, in the absence of an
applicable exemption therefrom, (a) each Holder that is a broker-dealer electing
to exchange Certificates, acquired for its own account as a result of
market-making activities or other trading activities, for Exchange Certificates
(an "Exchanging Dealer"), is required to deliver a prospectus containing the
information set forth in Annex A hereto on the cover, in Annex B hereto in the
"Exchange Offer Procedures" section and the "Purpose of the Exchange Offer"
section, and in Annex C hereto in the "Plan of Distribution" section, in
connection with a sale of any such Exchange Certificates received by that
Exchanging Dealer pursuant to the Registered Exchange Offer, and (b) if the
Initial Purchasers are permitted to and elect to sell Exchange Certificates
acquired in exchange for Certificates constituting any portion of an unsold
allotment, they are required to deliver a prospectus containing the information
required by Item 507 or 508 of Regulation S-K under the Securities Act, as
applicable, in connection with that sale.

      The Company shall include in the prospectus contained in the Exchange
Offer Registration Statement a section titled "Plan of Distribution," reasonably
acceptable to the Initial Purchasers, that contains a summary statement of the
positions taken or policies made by the staff of the


                                       2
   44


Commission with respect to the potential "underwriter" status of any
broker-dealer that is the beneficial owner (as defined in Rule 13d-3 under the
Exchange Act) of Exchange Certificates received by that broker-dealer in the
Registered Exchange Offer (a "Participating Broker-Dealer"), whether those
positions or policies have been publicly disseminated by the staff of the
Commission or, in the reasonable judgment of the Initial Purchasers based on
advice of counsel (which may be in-house counsel), represent the prevailing
views of the staff of the Commission.

      The Company shall use its best efforts to keep the Exchange Offer
Registration Statement effective and to amend and supplement the prospectus
contained therein, in order to permit that prospectus to be lawfully delivered
by the Initial Purchasers and all Exchanging Dealers subject to the prospectus
delivery requirements of the Securities Act, and shall make that prospectus
available to the Initial Purchasers and those Exchanging Dealers for such period
of time after the consummation of the Registered Exchange Offer as those persons
must comply with those requirements in order to resell the Exchange
Certificates; however, that period shall not exceed 120 days (unless extended
pursuant to Section 3(j) below), and those persons are not authorized by the
Company to deliver and shall not deliver any such prospectus after the
expiration of that period in connection with the resales contemplated by this
paragraph.

      The Company shall make available for a period of 120 days after the
consummation of the Registered Exchange Offer a copy of the prospectus, and any
amendment or supplement thereto, forming part of the Exchange Offer Registration
Statement, to any broker-dealer for use in connection with any resale of any
Exchange Certificates. The Certificates and the Exchange Certificates are herein
collectively called the "Securities."

      In connection with the Registered Exchange Offer, the Company shall:

                  mail to each Holder a copy of the prospectus forming part of
      the Exchange Offer Registration Statement, together with an appropriate
      letter of transmittal and related documents;

                  keep the Registered Exchange Offer open for not less than 30
      days (or longer, if required by applicable law) after the date notice
      thereof is mailed to the Holders;

                  utilize the services of a depositary for the Registered
      Exchange Offer with an address in the Borough of Manhattan, The City of
      New York, which may be the Trustee or an affiliate of the Trustee;

                  permit Holders to withdraw tendered Certificates at any time
      prior to the close of business, New York time, on the last business day on
      which the Registered Exchange Offer remains open; and

                  otherwise comply in all material respects with all
      applicable laws.

            As soon as practicable after the close of the Registered Exchange
      Offer, the Company shall:


                                       3
   45


                  accept for exchange all the Certificates validly tendered
      and not withdrawn pursuant to the Registered Exchange Offer;

                  deliver, or cause to be delivered, to the Trustee for
      cancellation all the Certificates so accepted for exchange; and

                  issue, and cause the Trustee to authenticate and deliver
      promptly to each Holder of the Certificates of either series, Exchange
      Certificates of the same series, equal in principal amount to the
      Certificates of that series of that Holder so accepted for exchange.

      The Pass Through Trust Agreements will provide that the Exchange
Certificates will not be subject to the transfer restrictions set forth in the
Pass Through Trust Agreements and that the Certificates and the Exchange
Certificates will vote and consent together on all matters as one class and not
as separate classes on any matter.

      Interest on each Exchange Certificate issued pursuant to the Registered
Exchange Offer will accrue from the last interest payment date on which interest
was paid on the Certificates surrendered in exchange therefor or, if no interest
has been paid on those Certificates, from the date of original issue of those
Certificates.

      Each Holder participating in the Registered Exchange Offer will be
required to represent to the Company at the time of the consummation of the
Registered Exchange Offer:

            (a) that any Exchange Certificate received by that Holder will be
      acquired in the ordinary course of business;

            (b) that the Holder will have no arrangement or understanding with
      any person to participate in the distribution of the Certificates or the
      Exchange Certificates within the meaning of the Securities Act;

            (c) that the Holder is not an "affiliate," as defined in Rule 405 of
      the Securities Act, of the Company or if it is an affiliate, that Holder
      will comply with the registration and prospectus delivery requirements of
      the Securities Act to the extent applicable;

            (d) if that Holder is not a broker-dealer, that it is not engaged
      in, and does not intend to engage in, any distribution of the Exchange
      Certificates; and

            (e) if that Holder is a broker-dealer, that it will receive Exchange
      Certificates for its own account in exchange for Certificates that were
      acquired as a result of market-making activities or other trading
      activities and that it will deliver a prospectus in connection with any
      resale of those Exchange Certificates.

      Notwithstanding any other provision hereof, the Company will ensure that
(a) any Exchange Offer Registration Statement and any amendment thereto and any
prospectus forming part thereof and any supplement thereto complies in all
material respects with the Securities Act and the rules and regulations
thereunder, (b) any Exchange Offer Registration Statement and any


                                       4
   46


amendment thereto will not, when it becomes effective, contain an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, and (c) any prospectus
forming part of any Exchange Offer Registration Statement, and any supplement to
that prospectus, at the time of issuance will not include an untrue statement of
a material fact or omit to state a material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading; provided, however,
that with respect to clauses (b) and (c), the Company will not be liable for
written information relating to any Holder or Initial Purchaser furnished to the
Company by or on behalf of such Holder or Initial Purchaser specifically for
inclusion therein.

            Shelf Registration.

      If (a) the Company determines that a Registered Exchange Offer, as
contemplated by Section 1 hereof, is not available or may not be consummated as
soon as practicable after the last date the Registered Exchange Offer is open
because it would violate applicable law or the applicable interpretations of the
staff of the Commission, (b) the Registered Exchange Offer is not consummated
within 180 days after the date of original issue of the Transfer Restricted
Certificates, (c) the Initial Purchasers of the Transfer Restricted Certificates
so request with respect to the securities not eligible to be exchanged for
Exchange Certificates in the Registered Exchange Offer and held by them
following consummation of the Registered Exchange Offer, or (d) any Holder
(other than an Exchanging Dealer) is not eligible to participate in the
Registered Exchange Offer, or any Holder (other than an Exchanging Dealer) that
participates in the Registered Exchange Offer does not receive freely tradeable
Exchange Certificates on the date of the exchange for validly tendered (and not
withdrawn) Transfer Restricted Certificates:

                    The Company shall use its reasonable best efforts to prepare
      and file, as promptly as practicable, with the Commission and thereafter
      to cause to be declared effective a registration statement (the "Shelf
      Registration Statement" and, together with the Exchange Offer Registration
      Statement, a "Registration Statement") on an appropriate form under the
      Securities Act relating to the offer and sale of the Transfer Restricted
      Certificates, by the Holders thereof from time to time in accordance with
      the methods of distribution set forth in the Shelf Registration Statement
      and Rule 415 under the Securities Act (hereinafter, the "Shelf
      Registration"), but no Holder (other than the Initial Purchasers) is
      entitled to have any Transfer Restricted Certificates held by it covered
      by that Shelf Registration Statement unless that Holder agrees in writing
      to be bound by all the provisions of this Agreement applicable to that
      Holder; and provided, however, that with respect to Exchange Certificates
      which are attributable to Certificates constituting any portion of an
      unsold allotment held by an Initial Purchaser, the Company may, if
      permitted by current interpretations of the Commission's staff and, in the
      opinion of the Company's counsel, sufficient to cause the Exchange
      Certificates to be freely tradeable by such Initial Purchaser, file a
      post-effective amendment to the Exchange Offer Registration Statement
      containing the information required by Items 507 and 508 of Regulation
      S-K, as applicable, in satisfaction of its obligations under this
      subsection with respect thereto, and any such Exchange Offer Registration
      Statement, as so amended, shall be referred to


                                       5
   47


      herein as, and governed by the provisions herein applicable to, a Shelf
      Registration Statement.

                    The Company shall use all reasonable efforts to keep the
      Shelf Registration Statement continuously effective in order to permit the
      prospectus included therein to be lawfully delivered by the Holders of the
      relevant Securities, until the earlier of (A) the end of the period
      referred to in Rule 144(k) under the Securities Act after the original
      issue date of the Certificates expires (or the end of such longer period
      as may result from an extension pursuant to Section 3(j) below), provided
      that, if this clause (A) is relied upon, counsel to the Company shall have
      delivered to Morgan Stanley and Co. Incorporated, an opinion to the effect
      that the Certificates included in such Shelf Registration Statement will
      thereafter be freely tradeable by the Holders thereof without restriction,
      and (B) the date on which all the Securities covered by the Shelf
      Registration Statement have been sold pursuant thereto. Such period is
      hereinafter referred to as the "Shelf Registration Period."

                    Notwithstanding any provision of this Agreement to the
      contrary, the Company shall cause the Shelf Registration Statement and the
      related prospectus and any amendment or supplement thereto, as of the
      effective date of the Shelf Registration Statement, amendment or
      supplement, (A) to comply in all material respects with the applicable
      requirements of the Securities Act and the rules and regulations of the
      Commission and (B) not to contain any untrue statement of a material fact
      or omit to state a material fact required to be stated therein or
      necessary in order to make the statements therein, in light of the
      circumstances under which they were made, not misleading; provided,
      however, that with respect to clause (B), the Company will not be liable
      for written information relating to any Holder or Initial Purchaser
      furnished to the Company by or on behalf of such Holder or Initial
      Purchaser specifically for inclusion therein.

            Registration Procedures.

      In connection with any Shelf Registration contemplated by Section 2 hereof
and, to the extent applicable, any Registered Exchange Offer contemplated by
Section 1 hereof, the following provisions shall apply:

                The Company shall (i) furnish to the Initial Purchasers, prior
to the filing thereof with the Commission, a copy of the Registration Statement
and each amendment thereof and each supplement, if any, to the prospectus
included therein and shall not file any such Registration Statement or amendment
thereto or any prospectus or any supplement thereto (including any document
that, upon filing, would be incorporated or deemed to be incorporated by
reference therein and any amendment to any such document other than documents
required to be filed pursuant to the Exchange Act) to which the Initial
Purchasers shall reasonably object, except for any Registration Statement or
amendment thereto or prospectus or supplement thereto (a copy of which has been
previously furnished to the Initial Purchasers and their counsel (and, in the
case of a Shelf Registration Statement, the Holders and their counsel)) which
counsel to the Company has advised the Company in writing is required to be
filed, notwithstanding any such objection, in order to comply with applicable
law, (ii) include information substantially to the


                                       6
   48


effect set forth (A) in Annex A hereto on the cover, (B) in Annex B hereto in
the "Exchange Offer Procedures" section and the "Purpose of the Exchange Offer"
section, (C) in Annex C hereto in the "Plan of Distribution" section, of the
prospectus forming a part of the Exchange Offer Registration Statement, and (D)
include the information set forth in Annex D hereto in the Letter of Transmittal
delivered in connection with the Registered Exchange Offer, (iii) to the extent
required by law or interpretation of the staff of the Commission, if requested
by the Initial Purchasers, include the information required by Item 507 or 508
of Regulation S-K under the Securities Act, as applicable, in the prospectus
forming a part of the Exchange Offer Registration Statement, and (iv) to the
extent required by law or interpretation of the staff of the Commission, in the
case of a Shelf Registration Statement, include the names of the Holders who
propose to sell Securities pursuant to the Shelf Registration Statement as
selling securityholders.

                The Company shall notify promptly the Initial Purchasers, the
Holders and any Participating Broker-Dealer from whom the Company has received
prior written notice stating that it will be a Participating Broker-Dealer in
the Registered Exchange Offer (which notice pursuant to clauses (ii) through (v)
hereof shall be accompanied by an instruction to suspend the use of the
prospectus until the requisite changes have been made) and, if requested by the
Initial Purchasers, the Holders or any such Participating Broker-Dealer, confirm
such notice in writing:

                    when the Registration Statement or any amendment thereto has
      been filed with the Commission and when the Registration Statement or any
      post-effective amendment thereto has become effective;

                    of any request by the Commission for an amendment or
      supplement to the Registration Statement or the prospectus included
      therein or for additional information;

                    of the issuance by the Commission of any stop order
      suspending the effectiveness of the Registration Statement or the
      initiation of any proceeding for that purpose;

                    of the receipt by the Company or its legal counsel of any
      notification with respect to the suspension of the qualification of the
      Securities for sale in any jurisdiction or the initiation or threatening
      of any proceeding for that purpose;

                    of the happening of any event that requires the Company to
      make changes in the Registration Statement or the prospectus in order that
      the Registration Statement or the prospectus does not contain an untrue
      statement of a material fact or omit to state a material fact required to
      be stated therein or necessary to make the statements therein, in light of
      the circumstances under which they were made, not misleading; and

                    of any determination by the Company that a post-effective
      amendment to a Registration Statement would be appropriate.


                                       7
   49


                The Company shall make every reasonable effort to prevent the
issuance, and if issued to obtain the withdrawal at the earliest possible time,
of any order suspending the effectiveness of the Registration Statement and
shall provide prompt written notice to the Initial Purchasers and each Holder of
the withdrawal of any such order.

                The Company shall furnish to each Holder of Securities included
in the Shelf Registration, without charge, at least one conformed copy of the
Shelf Registration Statement and any post-effective amendment thereto, including
financial statements and schedules (without documents incorporated therein by
reference or exhibits thereto, unless a Holder so requests in writing).

                The Company shall deliver to the Initial Purchasers, and to any
other Holder that so requests, without charge, at least one conformed copy of
the Exchange Offer Registration Statement and any post-effective amendment
thereto, including financial statements and schedules (without documents
incorporated therein by reference or exhibits thereto, unless any such Holder or
the Initial Purchasers so request in writing).

                The Company shall deliver to each Holder of Securities included
in the Shelf Registration, without charge, as many copies of the prospectus
(including each preliminary prospectus) included in the Shelf Registration
Statement and any amendment or supplement thereto as that Holder may reasonably
request during the Shelf Registration Period. The Company consents, subject to
the provisions of this Agreement, to the use of the prospectus or any amendment
or supplement thereto by each of the selling Holders of the Securities in
connection with the offering and sale of the Securities covered by, and as
contemplated by, the prospectus, or any amendment or supplement thereto,
included in the Shelf Registration Statement.

                The Company shall deliver to each Initial Purchaser, any
Participating Broker-Dealer and any Exchanging Dealer, without charge, as many
copies of the final prospectus included in the Exchange Offer Registration
Statement and any amendment or supplement thereto as that person or entity may
reasonably request, during a period not exceeding 120 days following the
consummation of the Registered Exchange Offer. The Company consents, subject to
the provisions of this Agreement, to the use of the prospectus or any amendment
or supplement thereto by the Initial Purchasers, if necessary, any Participating
Broker-Dealer and any Exchanging Dealer and such other persons as may be
required to deliver a prospectus following the Registered Exchange Offer in
connection with the offering and sale of the Exchange Certificates covered by
the prospectus, or any amendment or supplement thereto, included in the Exchange
Offer Registration Statement, but no such person or entity is authorized by the
Company to deliver and no such person or entity shall deliver any such
prospectus after the expiration of the period referred to in the immediately
preceding sentence, in connection with any resale contemplated by this
paragraph.

                Prior to any public offering of Securities pursuant to any
Registration Statement, the Company shall use its reasonable best efforts to
register or qualify or cooperate with the Holders of the Securities included
therein and their respective counsel in connection with the registration or
qualification of the Securities for offer and sale under the securities or Blue
Sky


                                       8

laws of such states of the United States as any Holder of the Securities
reasonably requests in writing and shall do any and all other acts or things
necessary or advisable to enable that Holder to offer and sell in such
jurisdictions the Securities covered by that Registration Statement owned by
that Holder, but the Company is not required to (i) qualify generally or as a
foreign corporation to do business in any jurisdiction where it is not then so
qualified or (ii) take any action which would subject it to general service of
process or to taxation in any jurisdiction where it is not then so subject.

                The Company shall cooperate with the Holders of the Securities
to facilitate the timely preparation and delivery of certificates representing
the Securities to be sold pursuant to any Shelf Registration Statement free of
any restrictive legend and in such denominations (consistent with the provisions
of the Pass Through Trust Agreements) and registered in such names as the
Holders may request at least two business days prior to closing of any sale of
the Securities pursuant to such Shelf Registration Statement.

                If any event contemplated by paragraphs (ii) through (vi) of
Section 3(b) above occurs during the period in which the Company is required to
maintain an effective Registration Statement, the Company shall promptly prepare
and file a post-effective amendment to the Registration Statement or a
supplement to the related prospectus and any other required document so that, as
thereafter delivered to Holders of the Certificates or purchasers of Securities,
the prospectus will not contain an untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances under which they were
made, not misleading. If the Company notifies the Initial Purchasers, the
Holders of the Securities and any known Participating Broker-Dealer in
accordance with paragraphs (ii) through (vi) of Section 3(b) above to suspend
the use of the prospectus until the requisite changes to the prospectus have
been made, then the Initial Purchasers, the Holders of the Securities and any
such Participating Broker-Dealer shall suspend use of that prospectus until the
Company has amended or supplemented the prospectus to correct that misstatement
or omission, and the period of effectiveness of the Shelf Registration Statement
provided for in Section 2(b) above and the Exchange Offer Registration Statement
provided for in Section 1 above shall each be extended by the number of days
from and including the date of the giving of that notice to and including the
date when the Initial Purchasers, the Holders of the Securities and any known
Participating Broker-Dealer shall have received that amended or supplemented
prospectus pursuant to this Section 3(j), but the minimum time period before the
Company is entitled to close the Registered Exchange Offer will be extended only
to the extent required by the Commission. Each Initial Purchaser, Holder and
Participating Broker-Dealer agrees that on receipt of any such notice from the
Company it will not distribute copies of the prospectus that are the subject of
that notice and will retain those copies in its files.

                Not later than the effective date of the applicable Registration
Statement, the Company will obtain a CUSIP number for each series of the
Transfer Restricted Certificates or the Exchange Certificates, as the case may
be, and provide the Trustee with printed certificates for the Certificates or
the Exchange Certificates, as the case may be, in a form eligible for deposit
with The Depository Trust Company.

   51


                The Company will comply with all rules and regulations of the
Commission to the extent and so long as they are applicable to the Registered
Exchange Offer or the Shelf Registration and will make generally available to
its security holders (or otherwise provide in accordance with Section 11(a) of
the Securities Act) an earnings statement satisfying the provisions of Section
11(a) of the Securities Act, no later than 45 days after the end of the 12-month
period (or 90 days, if that period is a fiscal year) that begins with the first
month of the Company's first fiscal quarter commencing after the effective date
of the Registration Statement, which statement will cover that 12-month period.

                The Company shall cause the Pass Through Trust Agreements (and,
if necessary, the Lease Indentures (as defined pursuant to Section 1.1 of the
Pass Through Trust Agreements)) to be qualified under the Trust Indenture Act of
1939, as amended, in a timely manner and to contain any changes that are
necessary for that qualification. If that qualification would require the
appointment of a new trustee under either Pass Through Trust Agreement or any of
the Lease Indentures, the Company shall appoint a new trustee thereunder
pursuant to the applicable provisions thereof. If required by the Commission,
the Company will also register the Lessor Notes issued pursuant to the Lease
Indentures.

                The Company will require each Holder of Securities to be sold
pursuant to any Shelf Registration Statement to furnish to the Company such
information regarding that Holder and the distribution of the Securities as the
Company may from time to time reasonably request for inclusion in the Shelf
Registration Statement, and to provide comments on the Shelf Registration
Statement, and the Company may exclude from that registration the Securities of
any Holder that unreasonably fails to furnish that information and those
comments within a reasonable time after receiving that request.

                In the case of any Shelf Registration, the Company shall enter
into such customary agreements (including, if requested, an underwriting
agreement in customary form) and take all such other action, if any, as the
Holders of a majority of the Securities being sold shall reasonably request in
order to facilitate the disposition of the Securities pursuant to that Shelf
Registration.

                In the case of any Shelf Registration, the Company shall make
available for inspection by a representative of the Holders of Securities being
sold, their counsel and an accountant retained by those Holders, in a manner
designed to permit underwriters to satisfy their due diligence investigation
under the Securities Act, all financial and other records, pertinent corporate
documents and properties of the Company customarily inspected by underwriters in
primary underwritten offerings and shall cause the officers, directors and
employees of the Company and its subsidiaries to supply all information
reasonably requested by, and customarily supplied in connection with primary
underwritten offerings to, any such representative, attorney or accountant in
connection with that registration, but any records, information or documents
that are designated by the Company as confidential at the time of delivery
thereof shall be kept confidential by those persons, unless (i) those records,
information or documents are in the public domain or otherwise publicly
available, (ii) disclosure of those records, information or documents is
required by a court or administrative order or (iii) disclosure of those
records, information or


                                       10
   52


documents, in the written opinion of counsel to those persons, is otherwise
required by law (including, without limitation, pursuant to the Securities Act).

                In the case of any Shelf Registration, the Company, if requested
by any Holder of Securities covered thereby, shall: (i) cause its counsel to
deliver an opinion and updates thereof relating to the Securities in customary
form addressed to the selling Holder and the managing underwriters, if any,
covering matters customarily covered in opinions requested in underwritten
offerings; (ii) cause its officers to execute and deliver such documents and
certificates and updates thereof as may be reasonably requested by any
underwriter of the applicable Securities, and which are customarily delivered in
underwritten offerings, to evidence the continued validity of the
representations and warranties of the Company made pursuant to, and to evidence
compliance with any customary conditions contained in, an underwriting
agreement; and (iii) cause its independent public accountants to provide to the
selling Holders of the applicable Securities (and any underwriter therefor) a
comfort letter in customary form and covering matters of the type customarily
covered in comfort letters in connection with primary underwritten offerings,
subject to receipt of appropriate documentation as contemplated, and only if
permitted, by Statement of Auditing Standards No. 72.

                If a Registered Exchange Offer is to be consummated, upon
delivery of the Certificates by Holders to the Company (or to any other Person
designated by the Company) in exchange for the Exchange Certificates, the
Company shall mark, or caused to be marked, on the Certificates so exchanged
that those Certificates are being canceled in exchange for the Exchange
Certificates, and in no event shall the Certificates be marked as paid or
otherwise satisfied.

                If any broker-dealer registered under the Exchange Act
underwrites any Securities or participates as a member of an underwriting
syndicate or selling group or "assists in the distribution" (within the meaning
of the Conduct Rules of the National Association of Securities Dealers, Inc.
("NASD")) thereof, whether as a Holder of those Securities or as an underwriter,
a placement or sales agent or a broker or dealer in respect thereof, or
otherwise, the Company shall assist such broker-dealer in complying with the
requirements of those Rules and By-Laws, including by (i) if those Rules,
including Rule 2720, shall so require, engaging a "qualified independent
underwriter" (as defined in Rule 2720) to participate in the preparation of the
Registration Statement relating to those Securities, to exercise usual standards
of due diligence in respect thereto and, if any portion of the offering
contemplated by that Registration Statement is an underwritten offering or is
made through a placement or sales agent, to recommend the yield of such
Securities, (ii) indemnifying any such qualified independent underwriter to the
extent of the indemnification of underwriters provided in Section 5 hereof, and
(iii) providing such information to that broker-dealer as may be required in
order for that broker-dealer to comply with the requirements of the Conduct
Rules of the NASD.

            Registration Expenses.

      The Company shall pay all fees and expenses incident to the performance of
or compliance with this Agreement by the Company including, without limitation:
(a) all Commission, stock exchange or NASD registration and filing fees; (b) all
fees and expenses incurred in connection with compliance with state securities
or Blue Sky laws (including reasonable fees and


                                       11
   53


disbursements of counsel for any underwriters or holders in connection with Blue
Sky qualification of any of the Securities); (c) all out of pocket expenses of
any persons in preparing or assisting in preparing, word processing, printing
and distributing any Registration Statement, any prospectus, any amendment or
supplement to either thereof, any underwriting agreement, securities sales
agreement or other document relating to the performance of and compliance with
this Agreement; (d) all rating agency fees; and (e) the fees and disbursements
of counsel for the Company and, in the event of a Shelf Registration, the
reasonable fees and disbursements of one firm of counsel designated by the
Holders of a majority in principal amount of the Securities covered thereby and
of the independent public accountants of the Company, including the expense of
any special audit or "cold comfort" letter required by or incident to that
performance and compliance, but excluding fees and expenses of counsel to the
underwriters and underwriting discounts and commissions and transfer taxes, if
any, relating to the sale or disposition of Securities by a Holder.

            Indemnification.

            The Company agrees to indemnify and hold harmless each Holder of
Securities, any Participating Broker-Dealer, and each person, if any, who
controls that Holder or Participating Broker-Dealer within the meaning of either
Section 15 of the Securities Act or Section 20 of the Exchange Act, or is under
common control with, or is controlled by, that Holder or Participating
Broker-Dealer, from and against any and all losses, claims, damages and
liabilities (including, without limitation, any legal or other expenses
reasonably incurred in connection with defending or investigating any such
action or claim) caused by any untrue statement or alleged untrue statement of a
material fact contained in a Registration Statement or the related prospectus
(as amended or supplemented if the Company shall have furnished any amendment or
supplement thereto), or caused by any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading, except insofar as such losses, claims, damages or liabilities
are caused by any such untrue statement or omission or alleged untrue statement
or omission based on information relating to that Holder or Participating
Broker-Dealer furnished to the Company in writing by that Holder or
Participating Broker-Dealer expressly for use therein, but the foregoing
indemnity in respect of any prospectus will not inure to the benefit of any
Holder or Participating Broker-Dealer from whom the person asserting any such
losses, claims, damages or liabilities purchased Securities, or any person
controlling or affiliated with that Holder or Participating Broker-Dealer, if a
copy of an amendment or supplement to the prospectus (furnished by the Company
on a timely basis) was not sent or given by or on behalf of that Holder or
Participating Broker-Dealer to that person, if required by law so to have been
delivered, at or prior to the written confirmation of the sale of the Securities
to that person, and if such amendment or supplement would have cured the defect
giving rise to that loss, claim, damage or liability.

                Each Participating Broker-Dealer and Holder of Securities,
severally and not jointly, agrees to indemnify and hold harmless the Company,
other selling Holders and Participating Broker-Dealers, directors of the
Company, the officers of the Company who sign a Registration Statement and each
person, if any, who controls the Company or any selling Holder or Participating
Broker-Dealer, within the meaning of either Section 15 of the Securities Act or


                                       12
   54


Section 20 of the Exchange Act to the same extent as the foregoing indemnity
from the Company to that Holder or Participating Broker-Dealer, but only with
reference to information relating to that Holder furnished to the Company in
writing by that Holder or Participating Broker-Dealer expressly for use in a
Registration Statement, any preliminary prospectus, prospectus or any amendment
or supplement to any thereof.

                If any proceeding (including any governmental investigation) is
instituted involving any person in respect of which indemnity may be sought
pursuant to either paragraph (a) or (b) above, that person (the "indemnified
party") shall promptly notify the person against whom that indemnity may be
sought (the "indemnifying party") in writing and the indemnifying party, upon
request of the indemnified party, shall retain counsel reasonably satisfactory
to the indemnified party to represent the indemnified party and any others the
indemnifying party may designate in that proceeding and shall pay the fees and
expenses of that counsel related to that proceeding. In any such proceeding, any
indemnified party may retain its own counsel, but the fees and expenses of that
counsel will be at the expense of that indemnified party unless (i) the
indemnifying party and the indemnified party shall have mutually agreed to the
retention of that counsel, or (ii) the named parties to any such proceeding
(including any impleaded parties) include both the indemnifying party and the
indemnified party and representation of both parties by the same counsel would
be inappropriate because of actual or potential differing interests between
them. It is understood that the indemnifying party shall not, in respect of the
legal expenses of any indemnified party in connection with any proceeding or
related proceedings in the same jurisdiction, be liable for the fees and
expenses of more than one separate firm (in addition to any local counsel) for
all such indemnified parties and that all such fees and expenses shall be
reimbursed as they are incurred. If an indemnified party includes (x) the
Initial Purchasers or such controlling persons of the Initial Purchasers, that
firm will be designated in writing by Morgan Stanley & Co. Incorporated; or (y)
Holders of Securities (other than the Initial Purchasers) or controlling persons
of those Holders, that firm will be designated in writing by the Holders of a
majority in aggregate principal amount of those Securities. In all other cases,
the Company will designate that firm. The indemnifying party will not be liable
for any settlement of any proceeding effected without its written consent, but
if settled with that consent or if there be a final judgment for the plaintiff,
the indemnifying party agrees to indemnify the indemnified party from and
against any loss or liability by reason of that settlement or judgment.
Notwithstanding the foregoing sentence, if at any time an indemnified party has
requested an indemnifying party to reimburse the indemnified party for fees and
expenses of counsel as contemplated by the second and third sentences of this
paragraph, the indemnifying party agrees that it will be liable for any
settlement of any proceeding effected without its written consent if (i) that
settlement is entered into more than 45 days after receipt by the indemnifying
party of the aforesaid request and (ii) the indemnifying party shall not have
reimbursed the indemnified party in accordance with that request prior to the
date of that settlement. No indemnifying party may, without the prior written
consent of the indemnified party, effect any settlement of any pending or
threatened proceeding in respect of which any indemnified party is or could have
been a party and indemnity could have been sought hereunder by that indemnified
party, unless that settlement includes an unconditional release of that
indemnified party from all liability on claims that are the subject matter of
that proceeding.


                                       13
   55


                To the extent the indemnification provided for in paragraph (a)
or (b) of this Section 5 is unavailable to an indemnified party or insufficient
in respect of any losses, claims, damages or liabilities referred to therein,
then each indemnifying party under that paragraph, in lieu of indemnifying that
indemnified party thereunder, shall contribute to the amount paid or payable by
that indemnified party as a result of those losses, claims, damages or
liabilities in such proportion as is appropriate to reflect the relative fault
of the indemnifying party or parties, on the one hand, and the indemnified party
or parties, on the other hand, in connection with the statements or omissions
that resulted in those losses, claims, damages or liabilities, as well as any
other relevant equitable considerations. The relative fault of the parties shall
be determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company or by that
Holder, Participating Broker-Dealer or other party and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
that statement or omission. The Holders' and Participating Broker-Dealers'
respective obligations to contribute pursuant to this Section 5 are several in
proportion to the respective amount of Certificates they have purchased, not
joint.

                The Company, each Participating Broker-Dealer and each Holder
agree that it would not be just or equitable if contribution pursuant to this
Section 5 were determined by pro rata allocation or by any other method of
allocation that does not take account of the equitable considerations referred
to in subsection (d) of this Section 5. The amount paid or payable by an
indemnified party as a result of the losses, claims, damages and liabilities
referred to in subsection (d) above is deemed to include, subject to the
limitations set forth above, any legal or other expenses reasonably incurred by
that indemnified party in connection with investigating or defending any such
action or claim. Notwithstanding the provisions of this Section 5, no Holder of
Securities is required to contribute any amount in excess of the amount by which
the total price at which the Securities sold by that Holder pursuant to a
Registration Statement were sold exceeds the amount of any damages that Holder
has otherwise been required to pay by reason of that untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act) is
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation.

                The indemnity and contribution provisions contained in this
Section 5 will remain operative and in full force and effect regardless of (i)
any termination of this Agreement, (ii) any investigation made by or on behalf
of any Holder or Participating Broker-Dealer or any person controlling that
Holder or Participating Broker-Dealer or by or on behalf of the Company, its
officers or directors or any person controlling the Company, and (iii) the sale
of the Securities. The remedies provided for in this Section 5 are not exclusive
and do not limit any rights or remedies that may otherwise be available to any
indemnified party at law or in equity.

            Additional Interest Under Certain Circumstances.

            Additional interest (the "Additional Interest") with respect to the
Securities will be assessed as follows if any of the following events occurs
(each event identified in clause (i) or (ii) below, a "Failure to Register"):


                                       14
   56


                  (i) If the Registered Exchange Offer is not consummated or a
      Shelf Registration Statement is not declared effective by the Commission
      on or prior to 180 days after the original issue date of the Certificates;
      or

                  (ii) If, after the 180th day after the Closing Date, and after
      any Shelf Registration Statement is declared effective, (A) such Shelf
      Registration Statement thereafter ceases to be effective during the Shelf
      Registration Period; or (B) such Shelf Registration Statement or the
      related prospectus ceases to be usable in connection with resales of
      Transfer Restricted Notes during the Shelf Registration Period (except as
      permitted in paragraph (b) of this Section 6) because either (1) any event
      occurs as a result of which the related prospectus forming part of such
      Shelf Registration Statement would include any untrue statement of a
      material fact or omit to state any material fact necessary to make the
      statements therein in the light of the circumstances under which they were
      made not misleading, or (2) it shall be necessary to amend such Shelf
      Registration Statement, or supplement the related prospectus, to comply
      with the Securities Act or the Exchange Act or the respective rules
      thereunder.

            Additional Interest shall accrue on the Transfer Restricted
Certificates of each series over and above the interest set forth in the title
of the Certificates of that series from and including the date on which any such
Failure to Register shall occur to but excluding the date on which all such
Failures to Register have been cured, at a rate of 0.50% per annum.

                A Failure to Register referred to in Section 6(a)(ii) is deemed
not to be continuing in relation to a Shelf Registration Statement or the
related prospectus if (i) that Failure to Register has occurred solely as a
result of (x) the filing of a post-effective amendment to such Shelf
Registration Statement to incorporate annual audited financial information with
respect to the Company, when such post-effective amendment is not yet effective
and needs to be declared effective to permit Holders to use the related
prospectus or (y) the occurrence of other material events or developments with
respect to the Company or its Affiliates that would need to be described in such
Shelf Registration Statement or the related prospectus, and (ii) in the case of
clause (y), the Company is proceeding promptly and in good faith to amend or
supplement such Shelf Registration Statement and related prospectus to describe
those events or, in the case of material developments that the Company
determines in good faith must remain confidential for business reasons, the
Company is proceeding promptly and in good faith to take such steps as are
necessary so that those developments need no longer remain confidential, but in
any case, if any Failure to Register (including any referred to in clause (x) or
(y), above) continues for a period in excess of 45 days, Additional Interest
will be payable in accordance with the above paragraph from the day following
the last day of that 45-day period until the date on which that Failure to
Register is cured.

                Any Additional Interest payable will be payable on the regular
interest payment dates with respect to the Certificates, in the same manner as
the manner in which regular interest is payable. The amount of Additional
Interest for any period will be determined by multiplying the applicable
Additional Interest rate by the principal amount of the applicable Certificates,
multiplied by a fraction, the numerator of which is the number of days that
Additional


                                       15
   57


Interest rate was applicable during that period (determined on the basis of a
360-day year comprised of twelve 30-day months), and the denominator of which is
360.

                "Transfer Restricted Certificate" means each Certificate until:
(i) the date on which that Certificate has been exchanged by a person other than
a broker-dealer for a freely transferable Exchange Certificate in the Registered
Exchange Offer; (ii) following the exchange by a broker-dealer in the Registered
Exchange Offer of a Transfer Restricted Certificate for an Exchange Certificate,
the date on which that Exchange Certificate is sold to a purchaser who receives
from that broker-dealer on or prior to the date of that sale a copy of the
prospectus constituting part of the Exchange Offer Registration Statement; (iii)
the date on which that Certificate has been effectively registered under the
Securities Act and disposed of in accordance with the Shelf Registration
Statement; or (iv) the date on which that Certificate is distributed to the
public pursuant to Rule 144 under the Securities Act or becomes freely tradeable
pursuant to Rule 144(k) under the Securities Act.

            Rules 144 and 144A.

      Subject to the proviso to the last sentence of the third paragraph of
Section 1, the Company shall use its best efforts to file the reports required
to be filed by it under the Securities Act and the Exchange Act in a timely
manner. If at any time the Company is not required to file those reports, it
will, upon the request of any Holder of Transfer Restricted Certificates, make
publicly available other information so long as is necessary to permit sales of
Securities pursuant to Rules 144 and 144A and otherwise as required by the Pass
Through Trust Agreements. The Company covenants that it will take such further
action as any Holder of Transfer Restricted Certificates may reasonably request,
all to the extent required from time to time to enable that Holder to sell
Transfer Restricted Certificates without registration under the Securities Act
within the limitation of the exemptions provided by Rules 144 and 144A
(including the requirements of Rule 144A(d)(4)). Upon request by an Initial
Purchaser, the Company will provide a copy of this Agreement to prospective
purchasers of Certificates identified to the Company by that Initial Purchaser.
Upon the request of any Holder of Transfer Restricted Certificates, the Company
shall deliver to that Holder a written statement as to whether it has complied
with those requirements. Notwithstanding the foregoing, nothing in this Section
7 requires the Company to register any of its securities under the Exchange Act.

            Underwritten Registrations.

      If any of the Transfer Restricted Certificates covered by any Shelf
Registration are to be sold in an underwritten offering, the investment banker
or investment bankers and manager or managers that will administer the offering
("Managing Underwriters") will be selected by the Holders of a majority in
aggregate principal amount of the Transfer Restricted Certificates included in
that offering, but the Managing Underwriters must be reasonably satisfactory to
the Company.

      No person may participate in any underwritten registration hereunder
unless that person (a) agrees to sell that person's Transfer Restricted
Certificates on the basis reasonably provided in any underwriting arrangements
approved by the persons entitled hereunder to approve those


                                       16
   58


arrangements, and (b) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of those underwriting arrangements.

            Miscellaneous.

            Amendments and Waivers.

            The provisions of this Agreement may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, except by the Company and the written consent of the Holders
of a majority in principal amount of the Securities affected thereby.

            Notices.

            All statements, requests, notices and agreements hereunder shall be

                No Inconsistent Agreements.

            The Company has not, as of the date hereof, entered into, nor will
it, on or after the date hereof, enter into, any agreement with respect to the
Securities that is inconsistent with the rights granted to the Holders herein or
that otherwise conflicts with this Agreement.

            This Agreement may be executed in any number of counterparts and by
the parties hereto in separate counterparts, each of which when so executed will
constitute an original and all of which taken together will constitute one and
the same agreement.

                Governing Law.

            This Agreement is governed by, and is to be construed in accordance
with, the laws of the State of New York without regard to principles of
conflicts of law.

                Severability.

            If any one or more of the provisions contained herein, or the
application thereof in any circumstance, is held invalid, illegal or
unenforceable, the validity, legality and enforceability of any such provision
in every other respect and of the remaining provisions contained herein is not
affected or impaired thereby.

                Securities Held by the Company.

            Whenever the consent or approval of Holders of a specified
percentage of principal amount of Securities is required hereunder, Securities
held by the Company or its affiliates will not be counted in determining whether
that consent or approval was given by the Holders of that required percentage.

agreement, please sign and return to the Company a counterpart hereof, whereupon
this instrument, along with all counterparts, will become a binding agreement

      Each broker-dealer that receives Exchange Certificates for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Certificates. The
Letter of Transmittal states that by so acknowledging and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act. This Prospectus, as it
may be amended or supplemented from time to time, may be used by a broker-dealer
in connection with resales of Exchange Certificates received in exchange for
Existing Certificates where such Existing Certificates were acquired by such
broker-dealer as a result of market-making activities or other trading
activities. The Company has agreed that, for a period of 120 days after the
consummation of the Exchange Offer, it will make this Prospectus available to
any broker-dealer for use in connection with any such resale. See "Plan of

                              PLAN OF DISTRIBUTION

      Each broker-dealer that receives Exchange Certificates for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of those Exchange Certificates. This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of Exchange Certificates received
in exchange for Certificates when those Certificates were acquired as a result
of market making activities or other trading activities. The Company has agreed
that, for a period of 120 days after the consummation of the Exchange Offer, it
will make this prospectus, as amended or supplemented, available to any
broker-dealer for use in connection with any such resale. In addition, until
_____________, all dealers effecting transactions in the Exchange Certificates
may be required to deliver a prospectus.(1)

      The Company will not receive any proceeds from any sale of Exchange
Certificates by broker-dealers. Exchange Certificates received by any
broker-dealer for its own account pursuant to the Exchange Offer may be sold
from time to time in one or more transactions in the over-the-counter market, in
negotiated transactions, through the writing of options on the Exchange
Certificates or a combination of those methods of resale, at market prices
prevailing at the time of resale or at prices related to those prevailing market
prices or negotiated prices. Any such resale may be made directly to purchasers
or to or through brokers or dealers who may receive compensation in the form of
commissions or concessions from any such broker-dealer or the purchasers of any
such Exchange Certificates. Any broker-dealer that resells Exchange Certificates
that were received by it for its own account pursuant to the Exchange Offer and
any broker or dealer that participates in a distribution of those Exchange
Certificates may be deemed to be an "underwriter" within the meaning of the
Securities Act and any profit on any such resale of Exchange Certificates and
any commission or concessions received by any such person may be deemed to be
underwriting compensation under the Securities Act. The Letter of Transmittal
states that, by acknowledging that it will deliver and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.

      For a period of 120 days after the Expiration Date the Company will
promptly send additional copies of this Prospectus, and any amendment or
supplement to this Prospectus, to any broker-dealer that requests those
documents in the Letter of Transmittal. The Company has agreed to pay all
expenses incident to the Exchange Offer other than commissions or concessions of
any broker or dealer and transfer taxes, if any, and will indemnify the Holders
of the Securities (including any broker-dealer) against certain liabilities,
including liabilities under the Securities Act.



(1) In addition, the legend required by Item 502(b) of Regulation S-K will
    appear on the back cover page of the Exchange Offer prospectus.
