            2. Registration Under the 1933 Act. (a) To the extent not prohibited
by any applicable law or applicable interpretation of the Staff of the SEC, the
Company shall use its reasonable best efforts (i) to cause to be filed with the
SEC an Exchange Offer Registration Statement covering the offer to the Holders
to exchange all of the Registrable Certificates for Exchange Certificates, (ii)
to have the Exchange Offer Registration Statement declared effective and (iii)
to have such Registration Statement remain effective until the closing of the
Exchange Offer. The Exchange Offer Registration Statement may also include the

The Company shall commence the Exchange Offer promptly after the Exchange Offer
Registration Statement has been declared effective by the SEC and use its
reasonable best efforts to have the Exchange Offer consummated not later than
the date that is 270 days (or, if such date is not a business day, the first
business day thereafter) after October 4, 2001. The Company shall, or shall
cause the Trustee to, commence the Exchange Offer by mailing the related
exchange offer Prospectus and accompanying documents to each Holder stating, in
addition to such other disclosures as are required by applicable law:

            (i) that the Exchange Offer is being made pursuant to this
      Registration Rights Agreement and that all Registrable Certificates
      validly tendered will be accepted for exchange;

            (ii) the dates of acceptance for exchange (which shall be a period
      of at least 30 days (or such shorter period as allowed by applicable law
      or SEC rules and interpretations) from the date such notice is mailed)
      (the "Exchange Dates");

            (iii) that any Registrable Certificate not tendered will remain
      outstanding and continue to accrue interest, but will not retain any
      rights under this Registration Rights Agreement;

                                       5
<PAGE>
            (iv) that Holders electing to have a Registrable Certificate
      exchanged pursuant to the Exchange Offer will be required to surrender
      such Registrable Certificate, together with the enclosed letters of
      transmittal, to the institution and at the address specified in the notice
      prior to the close of business on the last Exchange Date; and

            (v) that Holders will be entitled to withdraw their election, not
      later than the close of business on the last Exchange Date, by sending to
      the institution and at the address specified in the notice, a telegram,
      telex, facsimile transmission or letter setting forth the name of such
      Holder, the principal amount and class of Registrable Certificates
      delivered for exchange, and a statement that such Holder is withdrawing
      his election to have such Certificates exchanged.

            As soon as practicable after the last Exchange Date, the Company
shall or shall cause the Trustee to:

            (i) accept for exchange Registrable Certificates or portions thereof
      tendered and not validly withdrawn pursuant to the Exchange Offer; and

            (ii) deliver, or cause to be delivered, to the Trustee for
      cancellation all Registrable Certificates or portions thereof so accepted
      for exchange by the Company, and issue, and cause the Trustee to promptly
      authenticate and mail to each Holder, Exchange Certificates equal in
      principal amount to the principal amount of the Registrable Certificates
      surrendered by such Holder.

The Company shall use its reasonable best efforts to complete the Exchange Offer
as provided above and shall comply with the applicable requirements of the 1933
Act, the 1934 Act and other applicable laws, rules and regulations in connection
with the Exchange Offer. The Exchange Offer shall not be subject to any
conditions, other than that the Exchange Offer does not violate applicable law
or any applicable interpretation of the Staff of the SEC. The Company shall
inform the Placement Agents of the names and addresses of the Holders to whom
the Exchange Offer is made, and the Placement Agents shall have the right,
subject to applicable law, to contact such Holders and otherwise facilitate the
tender of Registrable Certificates in the Exchange Offer.

            Each Holder participating in the Exchange Offer shall be required to
represent to the Company at or prior to the consummation of the Exchange Offer
that (i) any Exchange Certificates received by such Holder will be acquired in
the ordinary course of business, (ii) such Holder will have no arrangements or
understanding with any person to participate in the distribution of the Class C
Certificates or the Exchange Certificates within the meaning of the 1933 Act,
and (iii) such Holder is not an "affiliate," as defined in Rule 405 of the 1933
Act, of the Company or any Trustee, nor a broker-dealer tendering Class C
Certificates acquired directly from the Company or any Trust for its own
account. If such Holder is a broker-dealer, it will be required to represent
that the Class C Certificates were acquired as a result of market-marking
activities or other trading activities and that it will deliver a prospectus in
connection with any resale of such Exchange Certificates. Each such Holder,
whether or not it is a broker-dealer,

                                       6
<PAGE>
shall also represent that it is not acting on behalf of any person that could
not truthfully make any of the foregoing representations contained in this
paragraph.

            Upon consummation of the Exchange Offer in accordance with this
Section 2(a), the provisions of this Agreement shall continue to apply (to the
extent applicable) solely with respect to Registrable Certificates held by the
Placement Agents or any Participating Broker-Dealers (as defined in Section
4(a)) as provided in (and subject to) Section 2(b)(ii), and the Company shall
have no further obligation to register Class C Certificates (other than such
Registrable Certificates of the Placement Agents and Participating
Broker-Dealers) pursuant to Section 2(b) of this Agreement.

            (b) In the event that (i) the Company determines that the Exchange
Offer Registration provided for in Section 2(a) above is not available or may
not be consummated as soon as practicable after the last Exchange Date because
it would violate applicable law or the applicable interpretations of the Staff
of the SEC, or (ii) the Exchange Offer has been completed and in the opinion of
counsel for the Placement Agents a Registration Statement must be filed and a
Prospectus must be delivered by the Placement Agents in connection with any
primary offering or sale of Registrable Certificates, the Company shall use its
reasonable best efforts to cause to be filed as soon as practicable after such
determination, date or notice of such opinion of counsel is given to the
Company, as the case may be, a Shelf Registration Statement providing for the
sale by the Holders of all of the Registrable Certificates (in the case of
clause (i) above) or by the Placement Agents (in the case of clause (ii) above)
and to have such Shelf Registration Statement declared effective by the SEC. In
the event the Company is required to file a Shelf Registration Statement solely
as a result of the matters referred to in clause (ii) of the preceding sentence,
the Company shall use its reasonable best efforts to file and have declared
effective by the SEC both an Exchange Offer Registration Statement pursuant to
Section 2(a) with respect to all Registrable Certificates and a Shelf
Registration Statement (which may be a combined Registration Statement with the
Exchange Offer Registration Statement) with respect to offers and sales of
Registrable Certificates held by the Placement Agents after completion of the
Exchange Offer. The Company agrees to use its reasonable best efforts to keep
the Shelf Registration Statement continuously effective for a period of two
years after its effective date with respect to the Registrable Certificates or
such shorter period that will terminate when all of the Registrable Certificates
covered by the Shelf Registration Statement have been sold pursuant to the Shelf
Registration Statement or may be freely sold pursuant to Rule 144(k) under the
1933 Act. The Company further agrees to supplement or amend the Shelf
Registration Statement if required by the rules, regulations or instructions
applicable to the registration form used by the Company for such Shelf
Registration Statement or by the 1933 Act or by any other rules and regulations
thereunder for shelf registration or if reasonably requested by a Holder with
respect to information relating to such Holder, and to use its best efforts to
cause any such amendment to become effective and such Shelf Registration
Statement to become usable as soon as thereafter practicable. The Company agrees
to furnish to the Holders of Registrable Certificates copies of any such
supplement or amendment promptly after its being used or filed with the SEC.

            (c) The Company shall pay all Registration Expenses in connection
with the registration pursuant to Section 2(a) or Section 2(b). Each Holder
shall pay all underwriting

                                       7
<PAGE>
discounts and commissions and transfer taxes, if any, relating to the sale or
disposition of such Holder's Registrable Certificates pursuant to the Shelf
Registration Statement.

            (d) An Exchange Offer Registration Statement pursuant to Section
2(a) hereof or a Shelf Registration Statement pursuant to Section 2(b) hereof
will not be deemed to have become effective unless it has been declared
effective by the SEC; provided, however, that if, after it has been declared
effective, the offering of Registrable Certificates pursuant to a Shelf
Registration Statement is interfered with by any stop order, injunction or other
order or requirement of the SEC or any other governmental agency or court, such
Shelf Registration Statement will be deemed not to have become effective during
the period of such interference until the offering of Registrable Certificates
pursuant to such Registration Statement may legally resume. In the event that
neither the consummation of the Exchange Offer nor the declaration by the SEC of
a Shelf Registration to be effective (each a "Registration Event") occurs on or
prior to the 270th day (or, if such 270th day is not a business day, the first
business day thereafter) after October 4, 2001, the interest rate per annum
borne by the Series C Equipment Notes shall be increased by 0.50%, effective
from and including such 270th day (or, if such 270th day is not a business day,
the first business day thereafter), to but excluding the date on which a
Registration Event occurs provided that if, to permit additional Holders of
Class C Certificates (who have notified the Company in writing its intention to
participate in the Exchange Offer) to participate in the Exchange Offer, the
length of such Exchange Offer is extended beyond such 270th day (or, if such
270th day is not a business day, the first business day thereafter), the
interest rate shall not be increased if the Exchange Offer is consummated within
60 days of such extension. In the event that the Shelf Registration Statement
required to be effective pursuant to Section 2(b) hereof ceases to be effective
at any time during the period specified by Section 2(b) hereof for more than 60
days, whether or not consecutive, during any 12-month period, the interest rate
borne by the Series C Equipment Notes shall be increased by 0.50% per annum from
the 61st day of the applicable 12-month period such Shelf Registration Statement
ceases to be effective until such time as the Shelf Registration Statement again
becomes effective.

            (e) Without limiting the remedies available to the Placement Agents
and the Holders, the Company acknowledges that any failure by the Company to
comply with its obligations under Section 2(a) and Section 2(b) hereof may
result in material irreparable injury to the Placement Agents or the Holders for
which there is no adequate remedy at law, that it will not be possible to
measure damages for such injuries precisely and that, in the event of any such
failure, each Placement Agent or any Holder may obtain such relief as may be
required to specifically enforce the Company's obligations under Section 2(a)
and Section 2(b) hereof.

            3. Registration Procedures. In connection with the obligations of
the Company with respect to the Registration Statements pursuant to Section 2(a)
and Section 2(b) hereof, the Company shall as reasonably expeditiously as
possible:

            (a) prepare and file with the SEC a Registration Statement on the
      appropriate form under the 1933 Act, which form (x) shall be selected by
      the Company, (y) shall, in the case of a Shelf Registration, be available
      for the sale of the Registrable Certificates by

                                       8
<PAGE>
      the selling Holders thereof and (z) shall comply as to form in all
      material respects with the requirements of the applicable form and include
      all financial statements required by the SEC to be filed therewith, and
      use its best efforts to cause such Registration Statement to become
      effective and remain effective in accordance with Section 2 hereof;

            (b) prepare and file with the SEC such amendments and post-effective
      amendments to each Registration Statement as may be necessary to (x) keep
      such Registration Statement effective for the applicable period under this
      Agreement, (y) cause each Prospectus to be supplemented by any required
      prospectus supplement and, as so supplemented, to be filed pursuant to
      Rule 424 under the 1933 Act and (z) keep each Prospectus current during
      the period described under Section 4(3) and Rule 174 under the 1933 Act
      that is applicable to transactions by brokers or dealers with respect to
      the Registrable Certificates or Exchange Certificates;

            (c) in the case of a Shelf Registration, furnish to each Holder of
      Registrable Certificates, to counsel for the Placement Agents, to counsel
      for the Holders and to each Underwriter of an Underwritten Offering of
      Registrable Certificates, if any, and each such Underwriter's Counsel,
      without charge, as many copies of each Prospectus, including each
      preliminary Prospectus, and any amendment or supplement thereto and such
      other documents as such Holder or Underwriter may reasonably request, in
      order to facilitate the public sale or other disposition of the
      Registrable Certificates; and the Company consents to the use of such
      Prospectus and any amendment or supplement thereto in accordance with
      applicable law by each of the selling Holders of Registrable Certificates
      and any such Underwriters in connection with the offering and sale of the
      Registrable Certificates covered by and in the manner described in such
      Prospectus or any amendment or supplement thereto in accordance with
      applicable law;

            (d) use its reasonable best efforts to register or qualify the
      Registrable Certificates under all applicable state securities or "blue
      sky" laws of such jurisdictions as any Holder of Registrable Certificates
      covered by a Registration Statement shall reasonably request in writing by
      the time the applicable Registration Statement is declared effective by
      the SEC, to cooperate with such Holders in connection with any filings
      required to be made with the National Association of Securities Dealers,
      Inc. and do any and all other acts and things which may be reasonably
      necessary or advisable to enable such Holder to consummate the disposition
      in each such jurisdiction of such Registrable Certificates owned by such
      Holder; provided, however, that the Company shall not be required to (i)
      qualify as a foreign corporation or as a dealer in securities in any
      jurisdiction where it would not otherwise be required to qualify but for
      this Section 3(d), (ii) file any general consent to service of process or
      (iii) subject itself to taxation in any such jurisdiction if it is not so
      subject;

            (e) in the case of a Shelf Registration, notify each Holder of
      Registrable Certificates, counsel for the Holders and counsel for the
      Placement Agents promptly and, if requested by any such Holder or counsel,
      confirm such advice in writing, (i) when a Registration Statement has
      become effective and when any post-effective amendment thereto has been
      filed and becomes effective, (ii) of any request by the SEC or any state

                                       9
<PAGE>
      securities authority for amendments and supplements to a Registration
      Statement and Prospectus or for material additional information after the
      Registration Statement has become effective, (iii) of the issuance by the
      SEC or any state securities authority of any stop order suspending the
      effectiveness of a Registration Statement or the initiation of any
      proceedings for that purpose, (iv) if, between the effective date of a
      Registration Statement and the closing of any sale of Registrable
      Certificates covered thereby, the representations and warranties of the
      Company contained in any underwriting agreement, securities sales
      agreement or other similar agreement, if any, relating to the offering
      cease to be true and correct in all material respects or if the Company
      receives any notification with respect to the suspension of the
      qualification of the Registrable Certificates for sale in any jurisdiction
      or the initiation of any proceeding for such purpose, (v) of the happening
      of any event during the period a Shelf Registration Statement is effective
      which makes any statement made in such Registration Statement or the
      related Prospectus untrue in any material respect or which requires the
      making of any changes in such Registration Statement or Prospectus in
      order to make the statements therein (in the case of the Prospectus, in
      light of the circumstances under which they were made) not misleading and
      (vi) of any determination by the Company that a post-effective amendment
      to a Registration Statement would be appropriate;

            (f) make every reasonable effort to obtain the withdrawal of any
      order suspending the effectiveness of a Registration Statement at the
      earliest possible moment and provide immediate notice to each Holder of
      the withdrawal of any such order;

            (g) in the case of a Shelf Registration, furnish to each Holder of
      Registrable Certificates, without charge, at least one conformed copy of
      each Registration Statement and any post-effective amendment thereto
      (without documents incorporated therein by reference or exhibits thereto,
      unless requested);

            (h) in the case of a Shelf Registration, cooperate with the selling
      Holders of Registrable Certificates to facilitate the timely preparation
      and delivery of certificates representing Registrable Certificates to be
      sold and not bearing any restrictive legends and enable such Registrable
      Certificates to be in such denominations (consistent with the provisions
      of the Pass Through Trust Agreement) and registered in such names as the
      selling Holders may reasonably request at least two business days prior to
      the closing of any sale of Registrable Certificates;

            (i) in the case of a Shelf Registration, upon the occurrence of any
      event contemplated by Section 3(e)(v) hereof, use its best efforts to
      prepare and file with the SEC a supplement or post-effective amendment to
      a Registration Statement or the related Prospectus or any document
      incorporated therein by reference or file any other required document so
      that, as thereafter delivered to the purchasers of the Registrable
      Certificates, such Prospectus will not contain any untrue statement of a
      material fact or omit to state a material fact necessary to make the
      statements therein, in light of the circumstances under which they were
      made, not misleading. The Company agrees to notify the Holders to suspend
      use of the Prospectus as promptly as practicable after the occurrence of
      such an

                                       10
<PAGE>
      event, and the Holders hereby agree to suspend use of the Prospectus until
      the Company has amended or supplemented the Prospectus to correct such
      misstatement or omission;

            (j) a reasonable time prior to the filing of any Registration
      Statement, any Prospectus, any amendment to a Registration Statement or
      amendment or supplement to a Prospectus or any document which is to be
      incorporated by reference into a Registration Statement or a Prospectus
      after initial filing of a Registration Statement, provide copies of such
      document to the Placement Agents and their counsel (and, in the case of a
      Shelf Registration Statement, the Holders and their counsel) and make such
      of the representatives of the Company as shall be reasonably requested by
      the Placement Agents or their counsel (and, in the case of a Shelf
      Registration Statement, the Holders or their counsel) available for
      discussion of such document, and shall not at any time file or make any
      amendment to the Registration Statement, any Prospectus or any amendment
      of or supplement to a Registration Statement or a Prospectus or any
      document which is to be incorporated by reference into a Registration
      Statement or a Prospectus, of which the Placement Agents and their counsel
      (and, in the case of a Shelf Registration Statement, the Holders and their
      counsel) shall not have previously been advised and furnished a copy or to
      which the Placement Agents or their counsel (and, in the case of a
      Registration Statement, the Holders or their counsel) shall object;

            (k) obtain a CUSIP number for all Exchange Certificates or
      Registrable Certificates, as the case may be, not later than the effective
      date of a Registration Statement;

            (l) cause the Pass Through Trust Agreement to be qualified under the
      Trust Indenture Act of 1939, as amended (the "TIA") in connection with the
      registration of the Exchange Certificates or Registrable Certificates, as
      the case may be, cooperate with the Trustee and the Holders to effect such
      changes to the Pass Through Trust Agreement as may be required for the
      Pass Through Trust Agreement to be so qualified in accordance with the
      terms of the TIA and execute, and use its best efforts to cause the
      Trustee to execute, all documents as may be required to effect such
      changes, and all other forms and documents required to be filed with the
      SEC to enable the Pass Through Trust Agreement to be so qualified in a
      timely manner;

            (m) in the case of a Shelf Registration, upon execution of customary
      confidentiality agreements reasonably satisfactory to the Company and its
      counsel, (other than a Placement Agent) make available for inspection by a
      representative of the Holders of the Registrable Certificates, any
      Underwriter participating in any disposition pursuant to such Shelf
      Registration Statement, and attorneys and accountants designated by the
      Holders, at reasonable times and in a reasonable manner, all financial and
      other records, pertinent documents and properties of the Company, and
      cause the respective officers, directors and employees of the Company to
      supply all information reasonably requested by any such representative,
      Underwriter, attorney or accountant in connection with a Shelf
      Registration Statement as shall be necessary to enable such persons to
      conduct a reasonable investigation within the meaning of Section 11 of the
      1933 Act;

                                       11
<PAGE>
            (n) use its reasonable best efforts to cause the Exchange
      Certificates or Registrable Certificates, as the case may be, to be rated
      by two nationally recognized statistical rating organizations (as such
      term is defined in Rule 436(g)(2) under the 1933 Act);

            (o) if reasonably requested by any Holder of Registrable
      Certificates covered by a Registration Statement, (i) promptly incorporate
      in a Prospectus supplement or post-effective amendment such information
      with respect to such Holder as such Holder reasonably requests to be
      included therein and (ii) make all required filings of such Prospectus
      supplement or such post-effective amendment as soon as the Company has
      received notification of the matters to be incorporated in such filing;
      and

            (p) in the case of a Shelf Registration, enter into such customary
      agreements and take all such other actions in connection therewith
      (including those requested by the Holders of a majority of the Registrable
      Certificates being sold) in order to expedite or facilitate the
      disposition of such Registrable Certificates including, but not limited
      to, an Underwritten Offering and in such connection, (i) to the extent
      possible, make such representations and warranties to the Holders and any
      Underwriters of such Registrable Certificates with respect to the business
      of the Company and its subsidiaries, the Registration Statement,
      Prospectus and documents incorporated by reference or deemed incorporated
      by reference therein, if any, in each case, in form, substance and scope
      as are customarily made by issuers to underwriters in underwritten
      offerings and confirm the same if and when requested, (ii) obtain opinions
      of counsel to the Company (which counsel and opinions, in form, scope and
      substance, shall be reasonably satisfactory to the Holders of a majority
      in principal amount of Registrable Certificates being sold and such
      Underwriters and their respective counsel) addressed to each selling
      Holder and Underwriter of Registrable Certificates, covering the matters
      customarily covered in opinions requested in underwritten offerings, (iii)
      obtain "cold comfort" letters from the independent certified public
      accountants of the Company (and, if necessary, any other certified public
      accountant of any subsidiary of the Company, or of any business acquired
      by the Company for which financial statements and financial data are or
      are required to be included in the Registration Statement) addressed to
      each selling Holder and Underwriter of Registrable Certificates, such
      letters to be in customary form and covering matters of the type
      customarily covered in "cold comfort" letters in connection with
      underwritten offerings, and (iv) deliver such documents and certificates
      as may be reasonably requested by the Holders of a majority in principal
      amount of the Registrable Certificates being sold or the Underwriters, and
      which are customarily delivered in underwritten offerings, to evidence the
      continued validity of the representations and warranties of the Company
      made pursuant to clause (i) above and to evidence compliance with any
      customary conditions contained in an underwriting agreement.

            In the case of a Shelf Registration Statement, the Company may
require each Holder of Registrable Certificates to furnish to the Company such
information regarding the Holder and the proposed distribution by such Holder of
such Registrable Certificates as the Company may from time to time reasonably
request in writing. The Company may exclude from

                                       12
<PAGE>
such registration the Registrable Certificates of any Holder who fails to
furnish such information within a reasonable time after receiving such request.

            In the case of a Shelf Registration Statement, each Holder agrees
that, upon receipt of any notice from the Company of the happening of any event
of the kind described in Section 3(e)(v) hereof, such Holder will forthwith
discontinue disposition of Registrable Certificates pursuant to a Shelf
Registration Statement until such Holder's receipt of the copies of the
supplemented or amended Prospectus contemplated by Section 3(i) hereof, and, if
so directed by the Company, such Holder will deliver to the Company (at the
Company's expense) all copies in its possession, other than permanent file
copies then in such Holder's possession, of the Prospectus covering such
Registrable Certificates current at the time of receipt of such notice. If the
Company shall give any such notice to suspend the disposition of Registrable
Certificates pursuant to a Registration Statement, the Company shall extend the
period during which the Registration Statement shall be maintained effective
pursuant to this Agreement by the number of days during the period from and
including the date of the giving of such notice to and including the date when
the Holders shall have received copies of the supplemented or amended Prospectus
necessary to resume such dispositions.

            The Holders of Registrable Certificates covered by a Shelf
Registration Statement who desire to do so may sell such Registrable
Certificates in an Underwritten Offering. In any such Underwritten Offering, the
investment banker or investment bankers and manager or managers (the
"Underwriters") that will administer the offering will be selected by the
Majority Holders of the Registrable Certificates included in such offering,
subject to the consent of the Company (which shall not be unreasonably
withheld).

            4. Participation of Broker-Dealers in Exchange Offer. (a) The Staff
of the SEC has taken the position that any broker-dealer that receives Exchange
Certificates for its own account in the Exchange Offer in exchange for Class C
Certificates that were acquired by such broker-dealer as a result of market
making or other trading activities (a "Participating Broker-Dealer") may be
deemed to be an "underwriter" within the meaning of the 1933 Act and must
deliver a prospectus meeting the requirements of the 1933 Act in connection with
any resale of such Exchange Certificates. No Participating Broker-Dealers other
than the Placement Agents and persons who have obtained the Company's prior
written consent to act as a market maker shall have any rights as Participating
Broker-Dealers under this Agreement.

            The Company understands that it is the Staff's position that if the
Prospectus contained in the Exchange Offer Registration Statement includes a
plan of distribution containing a statement to the above effect and the means by
which Participating Broker-Dealers may resell the Exchange Certificates, without
naming the Participating Broker-Dealers or specifying the amount of Exchange
Certificates owned by them, such Prospectus may be delivered by Participating
Broker-Dealers to satisfy their prospectus delivery obligation under the 1933
Act in connection with resales of Exchange Certificates for their own accounts,
so long as the Prospectus otherwise meets the requirements of the 1933 Act.

                                       13
<PAGE>
            (b) In light of Section 4(a) above, notwithstanding the other
provisions of this Agreement, the Company agrees that the provisions of this
Agreement as they relate to a Shelf Registration shall also apply to the
Exchange Offer Registration to the extent, and with such reasonable
modifications thereto as may be reasonably requested by the Placement Agents or
by one or more Participating Broker-Dealers, in each case as provided in clause
(ii) below, in order to expedite or facilitate the disposition of any Exchange
Certificates by Participating Broker-Dealers consistent with the positions of
the Staff recited in Section 4(a) above; provided that:

            (i) the Company shall not be required to amend or supplement the
      Prospectus contained in the Exchange Offer Registration Statement, as
      would otherwise be contemplated by Section 3(i), for a period exceeding 90
      days after the last Exchange Date (as such period may be discontinued and
      extended pursuant to the penultimate paragraph of Section 3 of this
      Agreement) and Participating Broker-Dealers shall not be authorized by the
      Company to deliver and shall not deliver such Prospectus after such period
      in connection with the resales contemplated by this Section 4; and

            (ii) the application of the Shelf Registration procedures set forth
      in Section 3 of this Agreement to an Exchange Offer Registration, to the
      extent not required by the positions of the Staff of the SEC or the 1933
      Act and the rules and regulations thereunder, will be in conformity with
      the reasonable request to the Company by the Placement Agents or with the
      reasonable request in writing to the Company by one or more broker-dealers
      who certify to the Placement Agents and the Company in writing that they
      anticipate that they will be Participating Broker-Dealers in accordance
      with Section 4(a); provided that in connection with such application of
      the Shelf Registration procedures set forth in Section 3 to an Exchange
      Offer Registration, the Company shall be obligated (x) to deal only with
      one entity representing the Participating Broker-Dealers, which shall be
      Morgan Stanley unless it elects not to act as such representative, (y) to
      pay the fees and expenses of only one counsel representing the
      Participating Broker-Dealers, which shall be counsel to the Placement
      Agents unless such counsel elects not to so act, and (z) to cause to be
      delivered only one, if any, "cold comfort" letter with respect to the
      Prospectus in the form existing on the last Exchange Date and with respect
      to each subsequent amendment or supplement, if any, effected during the
      period specified in clause (i) above.

            (c) The Placement Agents shall have no liability to the Company or
any Holder with respect to any request that it may make pursuant to Section 4(b)
above.

            5. Indemnification and Contribution. (a) The Company agrees to
indemnify and hold harmless the Placement Agents, each Holder and each Person,
if any, who controls any Placement Agent or any Holder within the meaning of
either Section 15 of the 1933 Act or Section 20 of the 1934 Act, or is under
common control with, or is controlled by, any Placement Agent or any Holder,
from and against all losses, claims, damages and liabilities (including, without
limitation, any legal or other expenses reasonably incurred by the Placement
Agent, any such Holder or any such controlling or affiliated Person in
connection with defending or

                                       14
<PAGE>
investigating any such action or claim) caused by any untrue statement or
alleged untrue statement of a material fact contained in any Registration
Statement (or any amendment thereto) pursuant to which Exchange Certificates or
Registrable Certificates were registered under the 1933 Act, including all
documents incorporated therein by reference, 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 not misleading, or caused by any
untrue statement or alleged untrue statement of a material fact contained in any
Prospectus (as amended or supplemented if the Company shall have furnished any
amendments or supplements thereto), or caused by any omission or alleged
omission to state therein a material fact 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
upon information relating to the Placement Agents or any Holder furnished to the
Company in writing through Morgan Stanley or any selling Holder expressly for
use therein provided, however, that the foregoing indemnity agreement shall not
inure to the benefit of any Holder to the extent that any such losses, claims,
damages or liabilities result from the fact that such Holder sold securities to
a person to whom there was not sent or given by or on behalf of such Holder (if
required by law so to have been delivered) a copy of the final Prospectus (in
the case of any preliminary Prospectus) or a prospectus amendment or supplement
(in the case of any Prospectus) at or prior to the written confirmation of the
sale of the Registrable Certificates to such person if the Company had
previously furnished copies thereof to such Holder and such untrue statement or
omission or alleged untrue statement or omission was corrected in such final
Prospectus or prospectus amendment or supplement, nor shall this indemnity
agreement inure to the benefit of any Holder from whom the person asserting any
such losses, claims, damages or liabilities purchased the Registrable
Certificates concerned if at the time of such purchase such Holder had received
written notice from the Company that the use of such Prospectus, amendment,
supplement or preliminary Prospectus was suspended as provided in the
penultimate paragraph of Section 3. In connection with any Underwritten Offering
permitted by Section 3, the Company will also indemnify the Underwriters, if
any, selling brokers, dealers and similar securities industry professionals
participating in the distribution, their officers and directors and each Person
who controls such Persons (within the meaning of the 1933 Act and the 1934 Act)
to the same extent as provided above with respect to the indemnification of the
Holders, if requested in connection with any Registration Statement.

            (b) Each Holder agrees, severally and not jointly, to indemnify and
hold harmless the Company, the Placement Agents and the other selling Holders
and each of their respective directors, officers who sign the Registration
Statement and each Person, if any, who controls the Company, any Placement Agent
and any other selling Holder within the meaning of either Section 15 of the 1933
Act or Section 20 of the 1934 Act to the same extent as the foregoing indemnity
from the Company to the Placement Agents and the Holders, but only with
reference to information relating to such Holder furnished to the Company in
writing by such Holder expressly for use in any Registration Statement (or any
amendment thereto) or any Prospectus (or any amendment or supplement thereto).

                                       15
<PAGE>
            (c) In case any proceeding (including any governmental
investigation) shall be instituted involving any Person in respect of which
indemnity may be sought pursuant to either of paragraph (a) or paragraph (b)
above, such Person (the "indemnified party") shall promptly notify the Person
against whom such 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 such
proceeding and shall pay the fees and disbursements of such counsel related to
such proceeding. In any such proceeding, any indemnified party shall have the
right to retain its own counsel, but the fees and expenses of such counsel shall
be at the expense of such indemnified party unless (i) the indemnifying party
and the indemnified party shall have mutually agreed to the retention of such
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
due to actual or potential differing interests between them. It is understood
that the indemnifying party shall not, in connection with any proceeding or
related proceedings in the same jurisdiction, be liable for (a) the fees and
expenses of more than one separate firm (in addition to any local counsel) for
the Placement Agents and all Persons, if any, who control any Placement Agent
within the meaning of either Section 15 of the 1933 Act or Section 20 of the
1934 Act, (b) the fees and expenses of more than one separate firm (in addition
to any local counsel) for the Company, its directors, its officers who sign the
Registration Statement and each Person, if any, who controls the Company within
the meaning of either such Section and (c) the fees and expenses of more than
one separate firm (in addition to any local counsel) for all Holders and all
Persons, if any, who control any Holders within the meaning of either such
Section, and that all such fees and expenses shall be reimbursed as they are
incurred. In such case involving the Placement Agents and Persons who control
the Placement Agents, such firm shall be designated in writing by Morgan
Stanley. In such case involving the Holders and such Persons who control
Holders, such firm shall be designated in writing by the Majority Holders. In
all other cases, such firm shall be designated by the Company. The indemnifying
party shall not be liable for any settlement of any proceeding effected without
its written consent (which consent shall not be unreasonably withheld) but, if
settled with such 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 such settlement or judgment. Notwithstanding
the foregoing sentence, if at any time an indemnified party shall have 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 shall be liable for any settlement of any
proceeding effected without its written consent if (i) such settlement is
entered into more than 90 days after receipt by such indemnifying party of the
aforesaid request and (ii) such indemnifying party shall not have reimbursed the
indemnified party for such fees and expenses of counsel in accordance with such
request prior to the date of such settlement. No indemnifying party shall,
without the prior written consent of the indemnified party, effect any
settlement of any pending or threatened proceeding in respect of which such
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party (which consent shall not be
unreasonably withheld),

                                       16
<PAGE>
unless such settlement includes an unconditional release of such indemnified
party from all liability on claims that are the subject matter of such
proceeding.

            (d) If the indemnification provided for in paragraph (a) or
paragraph (b) of this Section 5 is unavailable to an indemnified party or
insufficient in respect of any losses, claims, damages or liabilities, then each
indemnifying party under such paragraph, in lieu of indemnifying such
indemnified party thereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such 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 of the indemnified
party or parties on the other hand in connection with the statements or
omissions that resulted in such losses, claims, damages or liabilities, as well
as any other relevant equitable considerations. The relative fault of the
Company and the Holders 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 the Holders and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The Holders' respective obligations to contribute
pursuant to this Section 5(d) are several in proportion to the respective
principle amount of Registrable Certificates of such Holder that were registered
pursuant to a Registration Statement.

            (e) The Company 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 paragraph (d) above. The amount paid
or payable by an indemnified party as a result of the losses, claims, damages
and liabilities referred to in paragraph (d) above shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
Section 5, no Holder shall be required to indemnify or contribute any amount in
excess of the amount by which the total price at which Registrable Certificates
were sold by such Holder exceeds the amount of any damages that such Holder has
otherwise been required to pay by reason of such 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 1933 Act) shall be
entitled to contribution from any Person who was not guilty of such fraudulent
misrepresentation. The remedies provided for in this Section 5 are not exclusive
and shall not limit any rights or remedies which may otherwise be available to
any indemnified party at law or in equity.

            The indemnity and contribution provisions contained in this Section
5 shall 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
the Placement Agents, any Holder or any person controlling any Placement Agent
or any Holder, or by or on behalf of the Company, its officers or directors or
any person controlling the Company, (iii) acceptance of any of the Exchange
Certificates and (iv) any sale of Registrable Certificates pursuant to a Shelf
Registration Statement.

                                       17
<PAGE>
            6. Miscellaneous. (a) No Inconsistent Agreements. The Company has
not entered into, and on or after the date of this Agreement will not enter
into, any agreement that is inconsistent with the rights granted to the Holders
of Registrable Certificates in this Agreement or otherwise conflicts with the
provisions hereof. The rights granted to the Holders hereunder do not in any way
conflict with and are not inconsistent with the rights granted to the holders of
the Company's other issued and outstanding securities under any such agreements.

            (b) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given unless the Company has obtained the written consent of Holders
of at least a majority in aggregate principal amount of the outstanding
Registrable Certificates affected by such amendment, modification, supplement,
waiver or consent; provided, however, that no amendment, modification,
supplement, waiver or consents to any departure from the provisions of Section 5
hereof shall be effective as against any Holder of Registrable Certificates
unless consented to in writing by such Holder.

            (c) Notices. All notices and other communications provided for or

      (the "Exchange Dates");

      outstanding and continue to accrue interest, but will not retain any
      rights under this Registration Rights Agreement;

                                       5
<PAGE>
            (iv) that Holders electing to have a Registrable Certificate
      exchanged pursuant to the Exchange Offer will be required to surrender
      such Registrable Certificate, together with the enclosed letters of
      transmittal, to the institution and at the address specified in the notice
      prior to the close of business on the last Exchange Date; and

            (v) that Holders will be entitled to withdraw their election, not
      later than the close of business on the last Exchange Date, by sending to
      the institution and at the address specified in the notice, a telegram,
      telex, facsimile transmission or letter setting forth the name of such
      Holder, the principal amount and class of Registrable Certificates
      delivered for exchange, and a statement that such Holder is withdrawing
      his election to have such Certificates exchanged.

            As soon as practicable after the last Exchange Date, the Company
shall or shall cause the Trustee to:

            (i) accept for exchange Registrable Certificates or portions thereof
      tendered and not validly withdrawn pursuant to the Exchange Offer; and

            (ii) deliver, or cause to be delivered, to the Trustee for
      cancellation all Registrable Certificates or portions thereof so accepted
      for exchange by the Company, and issue, and cause the Trustee to promptly
      authenticate and mail to each Holder, Exchange Certificates equal in
      principal amount to the principal amount of the Registrable Certificates
      surrendered by such Holder.

The Company shall use its reasonable best efforts to complete the Exchange Offer
as provided above and shall comply with the applicable requirements of the 1933
Act, the 1934 Act and other applicable laws, rules and regulations in connection
with the Exchange Offer. The Exchange Offer shall not be subject to any
conditions, other than that the Exchange Offer does not violate applicable law
or any applicable interpretation of the Staff of the SEC. The Company shall
inform the Placement Agents of the names and addresses of the Holders to whom
the Exchange Offer is made, and the Placement Agents shall have the right,
subject to applicable law, to contact such Holders and otherwise facilitate the
tender of Registrable Certificates in the Exchange Offer.

            Each Holder participating in the Exchange Offer shall be required to
represent to the Company at or prior to the consummation of the Exchange Offer
that (i) any Exchange Certificates received by such Holder will be acquired in
the ordinary course of business, (ii) such Holder will have no arrangements or
understanding with any person to participate in the distribution of the Class D
Certificates or the Exchange Certificates within the meaning of the 1933 Act,
and (iii) such Holder is not an "affiliate," as defined in Rule 405 of the 1933
Act, of the Company or any Trustee, nor a broker-dealer tendering Class D
Certificates acquired directly from the Company or any Trust for its own
account. If such Holder is a broker-dealer, it will be required to represent
that the Class D Certificates 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 such Exchange Certificates. Each such Holder,
whether or not it is a broker-dealer,

                                       6
<PAGE>
shall also represent that it is not acting on behalf of any person that could
not truthfully make any of the foregoing representations contained in this
paragraph.

            Upon consummation of the Exchange Offer in accordance with this
Section 2(a), the provisions of this Agreement shall continue to apply (to the
extent applicable) solely with respect to Registrable Certificates held by the
Placement Agents or any Participating Broker-Dealers (as defined in Section
4(a)) as provided in (and subject to) Section 2(b)(ii), and the Company shall
have no further obligation to register Class D Certificates (other than such
Registrable Certificates of the Placement Agents and Participating
Broker-Dealers) pursuant to Section 2(b) of this Agreement.

            (b) In the event that (i) the Company determines that the Exchange
Offer Registration provided for in Section 2(a) above is not available or may
not be consummated as soon as practicable after the last Exchange Date because
it would violate applicable law or the applicable interpretations of the Staff
of the SEC, or (ii) the Exchange Offer has been completed and in the opinion of
counsel for the Placement Agents a Registration Statement must be filed and a
Prospectus must be delivered by the Placement Agents in connection with any
primary offering or sale of Registrable Certificates, the Company shall use its
reasonable best efforts to cause to be filed as soon as practicable after such
determination, date or notice of such opinion of counsel is given to the
Company, as the case may be, a Shelf Registration Statement providing for the
sale by the Holders of all of the Registrable Certificates (in the case of
clause (i) above) or by the Placement Agents (in the case of clause (ii) above)
and to have such Shelf Registration Statement declared effective by the SEC. In
the event the Company is required to file a Shelf Registration Statement solely
as a result of the matters referred to in clause (ii) of the preceding sentence,
the Company shall use its reasonable best efforts to file and have declared
effective by the SEC both an Exchange Offer Registration Statement pursuant to
Section 2(a) with respect to all Registrable Certificates and a Shelf
Registration Statement (which may be a combined Registration Statement with the
Exchange Offer Registration Statement) with respect to offers and sales of
Registrable Certificates held by the Placement Agents after completion of the
Exchange Offer. The Company agrees to use its reasonable best efforts to keep
the Shelf Registration Statement continuously effective for a period of two
years after its effective date with respect to the Registrable Certificates or
such shorter period that will terminate when all of the Registrable Certificates
covered by the Shelf Registration Statement have been sold pursuant to the Shelf
Registration Statement or may be freely sold pursuant to Rule 144(k) under the
1933 Act. The Company further agrees to supplement or amend the Shelf
Registration Statement if required by the rules, regulations or instructions
applicable to the registration form used by the Company for such Shelf
Registration Statement or by the 1933 Act or by any other rules and regulations
thereunder for shelf registration or if reasonably requested by a Holder with
respect to information relating to such Holder, and to use its best efforts to
cause any such amendment to become effective and such Shelf Registration
Statement to become usable as soon as thereafter practicable. The Company agrees
to furnish to the Holders of Registrable Certificates copies of any such
supplement or amendment promptly after its being used or filed with the SEC.

            (c) The Company shall pay all Registration Expenses in connection
with the registration pursuant to Section 2(a) or Section 2(b). Each Holder
shall pay all underwriting

discounts and commissions and transfer taxes, if any, relating to the sale or
disposition of such Holder's Registrable Certificates pursuant to the Shelf
Registration Statement.

            (d) An Exchange Offer Registration Statement pursuant to Section
2(a) hereof or a Shelf Registration Statement pursuant to Section 2(b) hereof
will not be deemed to have become effective unless it has been declared
effective by the SEC; provided, however, that if, after it has been declared
effective, the offering of Registrable Certificates pursuant to a Shelf
Registration Statement is interfered with by any stop order, injunction or other
order or requirement of the SEC or any other governmental agency or court, such
Shelf Registration Statement will be deemed not to have become effective during
the period of such interference until the offering of Registrable Certificates
pursuant to such Registration Statement may legally resume. In the event that
neither the consummation of the Exchange Offer nor the declaration by the SEC of
a Shelf Registration to be effective (each a "Registration Event") occurs on or
prior to the 270th day (or, if such 270th day is not a business day, the first
business day thereafter) after October 4, 2001, the interest rate per annum
borne by the Series D Equipment Notes shall be increased by 0.50%, effective
from and including such 270th day (or, if such 270th day is not a business day,
the first business day thereafter), to but excluding the date on which a
Registration Event occurs provided that if, to permit additional Holders of
Class D Certificates (who have notified the Company in writing its intention to
participate in the Exchange Offer) to participate in the Exchange Offer, the
length of such Exchange Offer is extended beyond such 270th day (or, if such
270th day is not a business day, the first business day thereafter), the
interest rate shall not be increased if the Exchange Offer is consummated within
60 days of such extension. In the event that the Shelf Registration Statement
required to be effective pursuant to Section 2(b) hereof ceases to be effective
at any time during the period specified by Section 2(b) hereof for more than 60
days, whether or not consecutive, during any 12-month period, the interest rate
borne by the Series D Equipment Notes shall be increased by 0.50% per annum from
the 61st day of the applicable 12-month period such Shelf Registration Statement
ceases to be effective until such time as the Shelf Registration Statement again
becomes effective.

            (e) Without limiting the remedies available to the Placement Agents
and the Holders, the Company acknowledges that any failure by the Company to
comply with its obligations under Section 2(a) and Section 2(b) hereof may
result in material irreparable injury to the Placement Agents or the Holders for
which there is no adequate remedy at law, that it will not be possible to
measure damages for such injuries precisely and that, in the event of any such
failure, each Placement Agent or any Holder may obtain such relief as may be
required to specifically enforce the Company's obligations under Section 2(a)
and Section 2(b) hereof.

            3. Registration Procedures. In connection with the obligations of
the Company with respect to the Registration Statements pursuant to Section 2(a)
and Section 2(b) hereof, the Company shall as reasonably expeditiously as
possible:

            (a) prepare and file with the SEC a Registration Statement on the
      appropriate form under the 1933 Act, which form (x) shall be selected by
      the Company, (y) shall, in the case of a Shelf Registration, be available
      for the sale of the Registrable Certificates by the selling Holders
      thereof and (z) shall comply as to form in all material respects with

                                       8
<PAGE>
      the requirements of the applicable form and include all financial
      statements required by the SEC to be filed therewith, and use its best
      efforts to cause such Registration Statement to become effective and
      remain effective in accordance with Section 2 hereof;

            (b) prepare and file with the SEC such amendments and post-effective
      amendments to each Registration Statement as may be necessary to (x) keep
      such Registration Statement effective for the applicable period under this
      Agreement, (y) cause each Prospectus to be supplemented by any required
      prospectus supplement and, as so supplemented, to be filed pursuant to
      Rule 424 under the 1933 Act and (z) keep each Prospectus current during
      the period described under Section 4(3) and Rule 174 under the 1933 Act
      that is applicable to transactions by brokers or dealers with respect to
      the Registrable Certificates or Exchange Certificates;

            (c) in the case of a Shelf Registration, furnish to each Holder of
      Registrable Certificates, to counsel for the Placement Agents, to counsel
      for the Holders and to each Underwriter of an Underwritten Offering of
      Registrable Certificates, if any, and each such Underwriter's Counsel,
      without charge, as many copies of each Prospectus, including each
      preliminary Prospectus, and any amendment or supplement thereto and such
      other documents as such Holder or Underwriter may reasonably request, in
      order to facilitate the public sale or other disposition of the
      Registrable Certificates; and the Company consents to the use of such
      Prospectus and any amendment or supplement thereto in accordance with
      applicable law by each of the selling Holders of Registrable Certificates
      and any such Underwriters in connection with the offering and sale of the
      Registrable Certificates covered by and in the manner described in such
      Prospectus or any amendment or supplement thereto in accordance with
      applicable law;

            (d) use its reasonable best efforts to register or qualify the
      Registrable Certificates under all applicable state securities or "blue
      sky" laws of such jurisdictions as any Holder of Registrable Certificates
      covered by a Registration Statement shall reasonably request in writing by
      the time the applicable Registration Statement is declared effective by
      the SEC, to cooperate with such Holders in connection with any filings
      required to be made with the National Association of Securities Dealers,
      Inc. and do any and all other acts and things which may be reasonably
      necessary or advisable to enable such Holder to consummate the disposition
      in each such jurisdiction of such Registrable Certificates owned by such
      Holder; provided, however, that the Company shall not be required to (i)
      qualify as a foreign corporation or as a dealer in securities in any
      jurisdiction where it would not otherwise be required to qualify but for
      this Section 3(d), (ii) file any general consent to service of process or
      (iii) subject itself to taxation in any such jurisdiction if it is not so
      subject;

            (e) in the case of a Shelf Registration, notify each Holder of
      Registrable Certificates, counsel for the Holders and counsel for the
      Placement Agents promptly and, if requested by any such Holder or counsel,
      confirm such advice in writing, (i) when a Registration Statement has
      become effective and when any post-effective amendment thereto has been
      filed and becomes effective, (ii) of any request by the SEC or any state

                                       9
<PAGE>
      securities authority for amendments and supplements to a Registration
      Statement and Prospectus or for material additional information after the
      Registration Statement has become effective, (iii) of the issuance by the
      SEC or any state securities authority of any stop order suspending the
      effectiveness of a Registration Statement or the initiation of any
      proceedings for that purpose, (iv) if, between the effective date of a
      Registration Statement and the closing of any sale of Registrable
      Certificates covered thereby, the representations and warranties of the
      Company contained in any underwriting agreement, securities sales
      agreement or other similar agreement, if any, relating to the offering
      cease to be true and correct in all material respects or if the Company
      receives any notification with respect to the suspension of the
      qualification of the Registrable Certificates for sale in any jurisdiction
      or the initiation of any proceeding for such purpose, (v) of the happening
      of any event during the period a Shelf Registration Statement is effective
      which makes any statement made in such Registration Statement or the
      related Prospectus untrue in any material respect or which requires the
      making of any changes in such Registration Statement or Prospectus in
      order to make the statements therein (in the case of the Prospectus, in
      light of the circumstances under which they were made) not misleading and
      (vi) of any determination by the Company that a post-effective amendment
      to a Registration Statement would be appropriate;

            (f) make every reasonable effort to obtain the withdrawal of any
      order suspending the effectiveness of a Registration Statement at the
      earliest possible moment and provide immediate notice to each Holder of
      the withdrawal of any such order;

            (g) in the case of a Shelf Registration, furnish to each Holder of
      Registrable Certificates, without charge, at least one conformed copy of
      each Registration Statement and any post-effective amendment thereto
      (without documents incorporated therein by reference or exhibits thereto,
      unless requested);

            (h) in the case of a Shelf Registration, cooperate with the selling
      Holders of Registrable Certificates to facilitate the timely preparation
      and delivery of certificates representing Registrable Certificates to be
      sold and not bearing any restrictive legends and enable such Registrable
      Certificates to be in such denominations (consistent with the provisions
      of the Pass Through Trust Agreement) and registered in such names as the
      selling Holders may reasonably request at least two business days prior to
      the closing of any sale of Registrable Certificates;

            (i) in the case of a Shelf Registration, upon the occurrence of any
      event contemplated by Section 3(e)(v) hereof, use its best efforts to
      prepare and file with the SEC a supplement or post-effective amendment to
      a Registration Statement or the related Prospectus or any document
      incorporated therein by reference or file any other required document so
      that, as thereafter delivered to the purchasers of the Registrable
      Certificates, such Prospectus will not contain any untrue statement of a
      material fact or omit to state a material fact necessary to make the
      statements therein, in light of the circumstances under which they were
      made, not misleading. The Company agrees to notify the Holders to suspend
      use of the Prospectus as promptly as practicable after the occurrence of
      such an

                                       10
<PAGE>
      event, and the Holders hereby agree to suspend use of the Prospectus until
      the Company has amended or supplemented the Prospectus to correct such
      misstatement or omission;

            (j) a reasonable time prior to the filing of any Registration
      Statement, any Prospectus, any amendment to a Registration Statement or
      amendment or supplement to a Prospectus or any document which is to be
      incorporated by reference into a Registration Statement or a Prospectus
      after initial filing of a Registration Statement, provide copies of such
      document to the Placement Agents and their counsel (and, in the case of a
      Shelf Registration Statement, the Holders and their counsel) and make such
      of the representatives of the Company as shall be reasonably requested by
      the Placement Agents or their counsel (and, in the case of a Shelf
      Registration Statement, the Holders or their counsel) available for
      discussion of such document, and shall not at any time file or make any
      amendment to the Registration Statement, any Prospectus or any amendment
      of or supplement to a Registration Statement or a Prospectus or any
      document which is to be incorporated by reference into a Registration
      Statement or a Prospectus, of which the Placement Agents and their counsel
      (and, in the case of a Shelf Registration Statement, the Holders and their
      counsel) shall not have previously been advised and furnished a copy or to
      which the Placement Agents or their counsel (and, in the case of a
      Registration Statement, the Holders or their counsel) shall object;

            (k) obtain a CUSIP number for all Exchange Certificates or
      Registrable Certificates, as the case may be, not later than the effective
      date of a Registration Statement;

            (l) cause the Pass Through Trust Agreement to be qualified under the
      Trust Indenture Act of 1939, as amended (the "TIA") in connection with the
      registration of the Exchange Certificates or Registrable Certificates, as
      the case may be, cooperate with the Trustee and the Holders to effect such
      changes to the Pass Through Trust Agreement as may be required for the
      Pass Through Trust Agreement to be so qualified in accordance with the
      terms of the TIA and execute, and use its best efforts to cause the
      Trustee to execute, all documents as may be required to effect such
      changes, and all other forms and documents required to be filed with the
      SEC to enable the Pass Through Trust Agreement to be so qualified in a
      timely manner;

            (m) in the case of a Shelf Registration, upon execution of customary
      confidentiality agreements reasonably satisfactory to the Company and its
      counsel, (other than a Placement Agent) make available for inspection by a
      representative of the Holders of the Registrable Certificates, any
      Underwriter participating in any disposition pursuant to such Shelf
      Registration Statement, and attorneys and accountants designated by the
      Holders, at reasonable times and in a reasonable manner, all financial and
      other records, pertinent documents and properties of the Company, and
      cause the respective officers, directors and employees of the Company to
      supply all information reasonably requested by any such representative,
      Underwriter, attorney or accountant in connection with a Shelf
      Registration Statement as shall be necessary to enable such persons to
      conduct a reasonable investigation within the meaning of Section 11 of the
      1933 Act;

                                       11
<PAGE>
            (n) use its reasonable best efforts to cause the Exchange
      Certificates or Registrable Certificates, as the case may be, to be rated
      by two nationally recognized statistical rating organizations (as such
      term is defined in Rule 436(g)(2) under the 1933 Act);

            (o) if reasonably requested by any Holder of Registrable
      Certificates covered by a Registration Statement, (i) promptly incorporate
      in a Prospectus supplement or post-effective amendment such information
      with respect to such Holder as such Holder reasonably requests to be
      included therein and (ii) make all required filings of such Prospectus
      supplement or such post-effective amendment as soon as the Company has
      received notification of the matters to be incorporated in such filing;
      and

            (p) in the case of a Shelf Registration, enter into such customary
      agreements and take all such other actions in connection therewith
      (including those requested by the Holders of a majority of the Registrable
      Certificates being sold) in order to expedite or facilitate the
      disposition of such Registrable Certificates including, but not limited
      to, an Underwritten Offering and in such connection, (i) to the extent
      possible, make such representations and warranties to the Holders and any
      Underwriters of such Registrable Certificates with respect to the business
      of the Company and its subsidiaries, the Registration Statement,
      Prospectus and documents incorporated by reference or deemed incorporated
      by reference therein, if any, in each case, in form, substance and scope
      as are customarily made by issuers to underwriters in underwritten
      offerings and confirm the same if and when requested, (ii) obtain opinions
      of counsel to the Company (which counsel and opinions, in form, scope and
      substance, shall be reasonably satisfactory to the Holders of a majority
      in principal amount of Registrable Certificates being sold and such
      Underwriters and their respective counsel) addressed to each selling
      Holder and Underwriter of Registrable Certificates, covering the matters
      customarily covered in opinions requested in underwritten offerings, (iii)
      obtain "cold comfort" letters from the independent certified public
      accountants of the Company (and, if necessary, any other certified public
      accountant of any subsidiary of the Company, or of any business acquired
      by the Company for which financial statements and financial data are or
      are required to be included in the Registration Statement) addressed to
      each selling Holder and Underwriter of Registrable Certificates, such
      letters to be in customary form and covering matters of the type
      customarily covered in "cold comfort" letters in connection with
      underwritten offerings, and (iv) deliver such documents and certificates
      as may be reasonably requested by the Holders of a majority in principal
      amount of the Registrable Certificates being sold or the Underwriters, and
      which are customarily delivered in underwritten offerings, to evidence the
      continued validity of the representations and warranties of the Company
      made pursuant to clause (i) above and to evidence compliance with any
      customary conditions contained in an underwriting agreement.

            In the case of a Shelf Registration Statement, the Company may
require each Holder of Registrable Certificates to furnish to the Company such
information regarding the Holder and the proposed distribution by such Holder of
such Registrable Certificates as the Company may from time to time reasonably
request in writing. The Company may exclude from

                                       12
<PAGE>
such registration the Registrable Certificates of any Holder who fails to
furnish such information within a reasonable time after receiving such request.

            In the case of a Shelf Registration Statement, each Holder agrees
that, upon receipt of any notice from the Company of the happening of any event
of the kind described in Section 3(e)(v) hereof, such Holder will forthwith
discontinue disposition of Registrable Certificates pursuant to a Shelf
Registration Statement until such Holder's receipt of the copies of the
supplemented or amended Prospectus contemplated by Section 3(i) hereof, and, if
so directed by the Company, such Holder will deliver to the Company (at the
Company's expense) all copies in its possession, other than permanent file
copies then in such Holder's possession, of the Prospectus covering such
Registrable Certificates current at the time of receipt of such notice. If the
Company shall give any such notice to suspend the disposition of Registrable
Certificates pursuant to a Registration Statement, the Company shall extend the
period during which the Registration Statement shall be maintained effective
pursuant to this Agreement by the number of days during the period from and
including the date of the giving of such notice to and including the date when
the Holders shall have received copies of the supplemented or amended Prospectus
necessary to resume such dispositions.

            The Holders of Registrable Certificates covered by a Shelf
Registration Statement who desire to do so may sell such Registrable
Certificates in an Underwritten Offering. In any such Underwritten Offering, the
investment banker or investment bankers and manager or managers (the
"Underwriters") that will administer the offering will be selected by the
Majority Holders of the Registrable Certificates included in such offering,
subject to the consent of the Company (which shall not be unreasonably
withheld).

            4. Participation of Broker-Dealers in Exchange Offer. (a) The Staff
of the SEC has taken the position that any broker-dealer that receives Exchange
Certificates for its own account in the Exchange Offer in exchange for Class D
Certificates that were acquired by such broker-dealer as a result of market
making or other trading activities (a "Participating Broker-Dealer") may be
deemed to be an "underwriter" within the meaning of the 1933 Act and must
deliver a prospectus meeting the requirements of the 1933 Act in connection with
any resale of such Exchange Certificates. No Participating Broker-Dealers other
than the Placement Agents and persons who have obtained the Company's prior
written consent to act as a market maker shall have any rights as Participating
Broker-Dealers under this Agreement.

            The Company understands that it is the Staff's position that if the
Prospectus contained in the Exchange Offer Registration Statement includes a
plan of distribution containing a statement to the above effect and the means by
which Participating Broker-Dealers may resell the Exchange Certificates, without
naming the Participating Broker-Dealers or specifying the amount of Exchange
Certificates owned by them, such Prospectus may be delivered by Participating
Broker-Dealers to satisfy their prospectus delivery obligation under the 1933
Act in connection with resales of Exchange Certificates for their own accounts,
so long as the Prospectus otherwise meets the requirements of the 1933 Act.

                                       13
<PAGE>
            (b) In light of Section 4(a) above, notwithstanding the other
provisions of this Agreement, the Company agrees that the provisions of this
Agreement as they relate to a Shelf Registration shall also apply to the
Exchange Offer Registration to the extent, and with such reasonable
modifications thereto as may be reasonably requested by the Placement Agents or
by one or more Participating Broker-Dealers, in each case as provided in clause
(ii) below, in order to expedite or facilitate the disposition of any Exchange
Certificates by Participating Broker-Dealers consistent with the positions of
the Staff recited in Section 4(a) above; provided that:

            (i) the Company shall not be required to amend or supplement the
      Prospectus contained in the Exchange Offer Registration Statement, as
      would otherwise be contemplated by Section 3(i), for a period exceeding 90
      days after the last Exchange Date (as such period may be discontinued and
      extended pursuant to the penultimate paragraph of Section 3 of this
      Agreement) and Participating Broker-Dealers shall not be authorized by the
      Company to deliver and shall not deliver such Prospectus after such period
      in connection with the resales contemplated by this Section 4; and

            (ii) the application of the Shelf Registration procedures set forth
      in Section 3 of this Agreement to an Exchange Offer Registration, to the
      extent not required by the positions of the Staff of the SEC or the 1933
      Act and the rules and regulations thereunder, will be in conformity with
      the reasonable request to the Company by the Placement Agents or with the
      reasonable request in writing to the Company by one or more broker-dealers
      who certify to the Placement Agents and the Company in writing that they
      anticipate that they will be Participating Broker-Dealers in accordance
      with Section 4(a); provided that in connection with such application of
      the Shelf Registration procedures set forth in Section 3 to an Exchange
      Offer Registration, the Company shall be obligated (x) to deal only with
      one entity representing the Participating Broker-Dealers, which shall be
      Morgan Stanley unless it elects not to act as such representative, (y) to
      pay the fees and expenses of only one counsel representing the
      Participating Broker-Dealers, which shall be counsel to the Placement
      Agents unless such counsel elects not to so act, and (z) to cause to be
      delivered only one, if any, "cold comfort" letter with respect to the
      Prospectus in the form existing on the last Exchange Date and with respect
      to each subsequent amendment or supplement, if any, effected during the
      period specified in clause (i) above.

            (c) The Placement Agents shall have no liability to the Company or
any Holder with respect to any request that it may make pursuant to Section 4(b)
above.

            5. Indemnification and Contribution. (a) The Company agrees to
indemnify and hold harmless the Placement Agents, each Holder and each Person,
if any, who controls any Placement Agent or any Holder within the meaning of
either Section 15 of the 1933 Act or Section 20 of the 1934 Act, or is under
common control with, or is controlled by, any Placement Agent or any Holder,
from and against all losses, claims, damages and liabilities (including, without
limitation, any legal or other expenses reasonably incurred by the Placement
Agent, any such Holder or any such controlling or affiliated Person in
connection with defending or

                                       14
<PAGE>
investigating any such action or claim) caused by any untrue statement or
alleged untrue statement of a material fact contained in any Registration
Statement (or any amendment thereto) pursuant to which Exchange Certificates or
Registrable Certificates were registered under the 1933 Act, including all
documents incorporated therein by reference, 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 not misleading, or caused by any
untrue statement or alleged untrue statement of a material fact contained in any
Prospectus (as amended or supplemented if the Company shall have furnished any
amendments or supplements thereto), or caused by any omission or alleged
omission to state therein a material fact 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
upon information relating to the Placement Agents or any Holder furnished to the
Company in writing through Morgan Stanley or any selling Holder expressly for
use therein provided, however, that the foregoing indemnity agreement shall not
inure to the benefit of any Holder to the extent that any such losses, claims,
damages or liabilities result from the fact that such Holder sold securities to
a person to whom there was not sent or given by or on behalf of such Holder (if
required by law so to have been delivered) a copy of the final Prospectus (in
the case of any preliminary Prospectus) or a prospectus amendment or supplement
(in the case of any Prospectus) at or prior to the written confirmation of the
sale of the Registrable Certificates to such person if the Company had
previously furnished copies thereof to such Holder and such untrue statement or
omission or alleged untrue statement or omission was corrected in such final
Prospectus or prospectus amendment or supplement, nor shall this indemnity
agreement inure to the benefit of any Holder from whom the person asserting any
such losses, claims, damages or liabilities purchased the Registrable
Certificates concerned if at the time of such purchase such Holder had received
written notice from the Company that the use of such Prospectus, amendment,
supplement or preliminary Prospectus was suspended as provided in the
penultimate paragraph of Section 3. In connection with any Underwritten Offering
permitted by Section 3, the Company will also indemnify the Underwriters, if
any, selling brokers, dealers and similar securities industry professionals
participating in the distribution, their officers and directors and each Person
who controls such Persons (within the meaning of the 1933 Act and the 1934 Act)
to the same extent as provided above with respect to the indemnification of the
Holders, if requested in connection with any Registration Statement.

            (b) Each Holder agrees, severally and not jointly, to indemnify and
hold harmless the Company, the Placement Agents and the other selling Holders
and each of their respective directors, officers who sign the Registration
Statement and each Person, if any, who controls the Company, any Placement Agent
and any other selling Holder within the meaning of either Section 15 of the 1933
Act or Section 20 of the 1934 Act to the same extent as the foregoing indemnity
from the Company to the Placement Agents and the Holders, but only with
reference to information relating to such Holder furnished to the Company in
writing by such Holder expressly for use in any Registration Statement (or any
amendment thereto) or any Prospectus (or any amendment or supplement thereto).

                                       15
<PAGE>
            (c) In case any proceeding (including any governmental
investigation) shall be instituted involving any Person in respect of which
indemnity may be sought pursuant to either of paragraph (a) or paragraph (b)
above, such Person (the "indemnified party") shall promptly notify the Person
against whom such 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 such
proceeding and shall pay the fees and disbursements of such counsel related to
such proceeding. In any such proceeding, any indemnified party shall have the
right to retain its own counsel, but the fees and expenses of such counsel shall
be at the expense of such indemnified party unless (i) the indemnifying party
and the indemnified party shall have mutually agreed to the retention of such
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
due to actual or potential differing interests between them. It is understood
that the indemnifying party shall not, in connection with any proceeding or
related proceedings in the same jurisdiction, be liable for (a) the fees and
expenses of more than one separate firm (in addition to any local counsel) for
the Placement Agents and all Persons, if any, who control any Placement Agent
within the meaning of either Section 15 of the 1933 Act or Section 20 of the
1934 Act, (b) the fees and expenses of more than one separate firm (in addition
to any local counsel) for the Company, its directors, its officers who sign the
Registration Statement and each Person, if any, who controls the Company within
the meaning of either such Section and (c) the fees and expenses of more than
one separate firm (in addition to any local counsel) for all Holders and all
Persons, if any, who control any Holders within the meaning of either such
Section, and that all such fees and expenses shall be reimbursed as they are
incurred. In such case involving the Placement Agents and Persons who control
the Placement Agents, such firm shall be designated in writing by Morgan
Stanley. In such case involving the Holders and such Persons who control
Holders, such firm shall be designated in writing by the Majority Holders. In
all other cases, such firm shall be designated by the Company. The indemnifying
party shall not be liable for any settlement of any proceeding effected without
its written consent (which consent shall not be unreasonably withheld) but, if
settled with such 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 such settlement or judgment. Notwithstanding
the foregoing sentence, if at any time an indemnified party shall have 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 shall be liable for any settlement of any
proceeding effected without its written consent if (i) such settlement is
entered into more than 90 days after receipt by such indemnifying party of the
aforesaid request and (ii) such indemnifying party shall not have reimbursed the
indemnified party for such fees and expenses of counsel in accordance with such
request prior to the date of such settlement. No indemnifying party shall,
without the prior written consent of the indemnified party, effect any
settlement of any pending or threatened proceeding in respect of which such
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party (which consent shall not be
unreasonably withheld),

                                       16

unless such settlement includes an unconditional release of such indemnified
party from all liability on claims that are the subject matter of such
proceeding.

            (d) If the indemnification provided for in paragraph (a) or
paragraph (b) of this Section 5 is unavailable to an indemnified party or
insufficient in respect of any losses, claims, damages or liabilities, then each
indemnifying party under such paragraph, in lieu of indemnifying such
indemnified party thereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such 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 of the indemnified
party or parties on the other hand in connection with the statements or
omissions that resulted in such losses, claims, damages or liabilities, as well
as any other relevant equitable considerations. The relative fault of the
Company and the Holders 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 the Holders and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The Holders' respective obligations to contribute
pursuant to this Section 5(d) are several in proportion to the respective
principle amount of Registrable Certificates of such Holder that were registered
pursuant to a Registration Statement.

            (e) The Company 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 paragraph (d) above. The amount paid
or payable by an indemnified party as a result of the losses, claims, damages
and liabilities referred to in paragraph (d) above shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
Section 5, no Holder shall be required to indemnify or contribute any amount in
excess of the amount by which the total price at which Registrable Certificates
were sold by such Holder exceeds the amount of any damages that such Holder has
otherwise been required to pay by reason of such 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 1933 Act) shall be
entitled to contribution from any Person who was not guilty of such fraudulent
misrepresentation. The remedies provided for in this Section 5 are not exclusive
and shall not limit any rights or remedies which may otherwise be available to
any indemnified party at law or in equity.

            The indemnity and contribution provisions contained in this Section
5 shall 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
the Placement Agents, any Holder or any person controlling any Placement Agent
or any Holder, or by or on behalf of the Company, its officers or directors or
any person controlling the Company, (iii) acceptance of any of the Exchange
Certificates and (iv) any sale of Registrable Certificates pursuant to a Shelf
Registration Statement.

                                       17

            6. Miscellaneous. (a) No Inconsistent Agreements. The Company has
not entered into, and on or after the date of this Agreement will not enter
into, any agreement that is inconsistent with the rights granted to the Holders
of Registrable Certificates in this Agreement or otherwise conflicts with the
provisions hereof. The rights granted to the Holders hereunder do not in any way
conflict with and are not inconsistent with the rights granted to the holders of
the Company's other issued and outstanding securities under any such agreements.

            (b) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given unless the Company has obtained the written consent of Holders
of at least a majority in aggregate principal amount of the outstanding
Registrable Certificates affected by such amendment, modification, supplement,
waiver or consent; provided, however, that no amendment, modification,
supplement, waiver or consents to any departure from the provisions of Section 5
hereof shall be effective as against any Holder of Registrable Certificates
unless consented to in writing by such Holder.

            (c) Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, registered
first-class mail, telex, telecopier, or any courier guaranteeing overnight
delivery (i) if to a Holder, at the most current address given by such Holder to
the Company by means of a notice given in accordance with the provisions of this
Section 6(c), which address initially is, with respect to the Placement Agents,
the address set forth in the Placement Agreement, and (ii) if to the Company,
initially at the Company's address set forth in the Placement Agreement and
thereafter at such other address, notice of which is given in accordance with
the provisions of this Section 6(c).

            All such notices and communications shall be deemed to have been
duly given: at the time delivered by hand, if personally delivered; five
business days after being deposited in the mail, postage prepaid, if mailed;
when answered back, if telexed; when receipt is acknowledged, if telecopied; and
on the next business day if timely delivered to an air courier guaranteeing
overnight delivery.

            Copies of all such notices, demands, or other communications shall
be concurrently delivered by the person giving the same to the Trustee, at the
address specified in the Pass Through Trust Agreement.

            (d) Successors and Assigns. This Agreement shall inure to the
benefit of and be binding upon the successors, assigns and transferees of each
of the parties, including, without limitation and without the need for an
express assignment, subsequent Holders; provided that nothing herein shall be
deemed to permit any assignment, transfer or other disposition of Registrable
Certificates in violation of the terms of the Placement Agreement or the Pass
Through Trust Agreement. If any transferee of any Holder shall acquire
Registrable Certificates, in any manner, whether by operation of law or
otherwise, such Registrable Certificates shall be held subject to all of the
terms of this Agreement, and by taking and holding such Registrable
Certificates, such Person shall be conclusively deemed to have agreed to be
bound by and to perform all of the terms and provisions of this Agreement and
such Person shall be entitled to

                                       18
<PAGE>
receive the benefits hereof. The Placement Agents (in their capacity as
Placement Agents) shall have no liability or obligation to the Company with
respect to any failure by any other Holder to comply with, or any breach by any
other Holder of, any of the obligations of such other Holder under this
Agreement.

            (e) Purchases and Sales of Certificates. The Company shall not, and
shall use its best efforts to cause its affiliates (as defined in Rule 405 under
the 1933 Act) to not, purchase and then resell or otherwise transfer any Class D
Certificates prior to consummation of the Exchange Offer or a Shelf Registration
Statement being declared effective.

            (f) Third Party Beneficiary. The Holders shall be third party
beneficiaries to the agreements made hereunder and shall have the right to
enforce such agreements directly to the extent they deem such enforcement
necessary or advisable to protect their rights hereunder.

            (g) Counterparts. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

            (h) Headings. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

            (i) Governing Law. This Agreement shall be governed by and construed
in accordance with the laws of the State of New York.

            (j) Severability. In the event that 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 shall not be affected or impaired thereby.

            (k) Trustee. The Trustee shall take such action as may be reasonably
requested by the Company in connection with the Company satisfying its
obligations arising under this Agreement.

                                       19
