each year, commencing August 15, 2001 at the rate of 7-3/4% per annum, until the
principal hereof is paid or made available for payment; provided, that in the
                                                        --------
event of a Non-Registration Event (as defined in the Registration Rights
Agreement dated as of February 27, 2001 by and among the Company and the initial
purchasers identified therein) with respect to the Securities of this series,
additional interest will accrue on such Securities at an annual rate of .25% for
the first 90-day period immediately following the occurrence of a Non-
Registration Event, and such annual rate will increase by an additional .25%
with respect to each subsequent 90-day period until all Non-Registration Events

from and including the date on which any such Non-Registration Event shall occur
to but excluding the date on which all such Non-Registration Events have been
cured. The Company will pay such additional interest on each Interest Payment
Date. Such additional interest will be in addition to any other interest payable
from time to time with respect to the Securities of this series. Interest shall
be computed on the basis of a 360-day year of twelve 30-day months. The interest
so payable, and punctually paid or duly provided for, on any Interest Payment

this Security (or one or more Predecessor Securities) is registered at the close
of business on the Regular Record Date for such interest, which shall be the
February 1 or August 1 (whether or not a Business Day), as the case may be, next
preceding such Interest Payment Date. Any such interest not so punctually paid
or duly provided for will forthwith cease to be payable to the Holder on such
Regular Record Date and may either be paid to the Person in whose name this
Security (or one or more Predecessor Securities) is registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest to
be fixed by the Trustee, notice whereof shall be given to Holders of Securities
of this series not less than 10 days prior to such Special Record Date, or be
paid at any time in any other lawful manner not inconsistent with the
requirements of any securities exchange on which the Securities of this series
may be listed, and upon such notice as may be required by such exchange, all as
more fully provided in said Indenture.

     Payment of the principal of (and premium, if any) and any such interest on
this Security will be made in immediately available funds at the office or
agency of the Company maintained for that purpose in the Borough of Manhattan,

provided, however, that at the option of the Company payment of interest may be
made by wire transfer in immediately available funds to an account maintained by
the person entitled thereto as specified in the Security Register.

     Reference is hereby made to the further provisions of this Security set
forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

obligatory for any purpose.

                             [REVERSE OF SECURITY]

     This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or more
series under an Indenture, dated as of October 15, 1994 (herein called the
"Indenture", which term shall have the meaning assigned to it in such
instrument), between the Company and The Chase Manhattan Bank, as Trustee
(herein called the "Trustee", which term includes any successor trustee under
the Indenture), and reference is hereby made to the Indenture for a statement of
the respective rights, limitations of rights, duties and immunities thereunder
of the Company, the Trustee and the Holders of the Securities and of the terms
upon which the Securities are and are to be authenticated and delivered. This
Security is one of the series designated on the face hereof. The Securities are
unsecured general obligations of the Company.

     The Securities of this series are subject to redemption upon not less than
30 days notice by mail, as a whole or in part, at the election of the Company at
a Redemption Price equal to the greater of (a) the principal amount of the
Securities being redeemed plus accrued and unpaid interest to the Redemption
Date or (2) the Make-Whole Amount for the Securities being redeemed.

     As used in this Security:

          "Adjusted Treasury Rate" means, with respect to any Redemption Date,
     (i) the yield, under the heading which represents the average for the
     immediately preceding week, appearing in the most recently published
     statistical release designated "H.15 (519)" or any successor publication
     which is published weekly by the Board of Governors of the Federal Reserve
     System and which establishes yields on actively traded United States
     Treasury securities adjusted to constant maturity under the caption
     "Treasury Constant Maturities," for the maturity corresponding to the
     Comparable Treasury Issue (if no maturity is within three months before or
     after the remaining term of the Securities being redeemed, yields for the
     two published maturities most closely corresponding to the Comparable
     Treasury Issue shall be determined and the Adjusted Treasury Rate shall be
     interpolated or extrapolated from such yields on a straight line basis,
     rounding to the nearest month) or (ii) if such release (or any successor
     release) is not published during the week preceding the calculation date or
     does not contain such yields, the rate per year equal to the semi-annual
     equivalent yield to maturity of the Comparable Treasury Issue (expressed as
     a percentage of its principal amount) equal to the Comparable Treasury
     Price for such Redemption Date, in each case calculated on the third
     Business Day preceding the Redemption Date, plus .30%.

          "Comparable Treasury Issue" means the United States Treasury security
     selected by the Quotation Agent as having a maturity comparable to the
     remaining term from the Redemption Date to the Stated Maturity of the
     principal amount of the Securities being redeemed that would be utilized,
     at the

                                       4
<PAGE>

     time of selection and in accordance with customary financial practice, in
     pricing new issues of corporate debt securities of comparable maturity to
     the remaining term of this Security.

          "Comparable Treasury Price" means, with respect to any Redemption
     Date, if clause (ii) of the Adjusted Treasury Rate is applicable, the
     average of three, or such lesser number as is obtained by the Trustee,
     Reference Treasury Dealer Quotations for such Redemption Date.

          "Make Whole Amount" means the sum, as determined by a Quotation
     Agent, of the present values of the principal amount of the Securities to
     be redeemed, together with scheduled payments of interest (exclusive of
     interest to the Redemption Rate) from the Redemption Date to the Stated
     Maturity of the principal amount of the Securities being redeemed, in each
     case discounted to the Redemption Date on a semi-annual basis, assuming a
     360-day year consisting of twelve 30-day months, at the Adjusted Treasury
     Rate, plus accrued interest on the principal amount of the Securities being
     redeemed to the Redemption Date.

          "Quotation Agent" means the Reference Treasury Dealer selected by the
     Trustee after consultation with the Company.

          "Reference Treasury Dealer" means any of Chase Securities Inc. and
     Credit Suisse First Boston Corporation, and their respective successors and
     assigns, and one other nationally recognized investment banking firm
     selected by the Company that is a primary U.S. Government securities
     dealer.

          "Reference Treasury Dealer Quotations" means, with respect to each
     Reference Treasury Dealer and any Redemption Date, the average, as
     determined by the Trustee, of the bid and asked prices for the Comparable
     Treasury Issue, expressed in each case as a percentage of its principal
     amount, quoted in writing to the Trustee by such Reference Treasury Dealer
     at 5:00 p.m., New York City time, on the third Business Day preceding such
     Redemption Date.

     In the event of redemption of this Security in part only, a new Security or
Securities of this series and of like tenor for the unredeemed portion hereof
will be issued in the name of the Holder hereof upon the cancellation hereof.

     The Indenture contains provisions for defeasance at any time of the entire
indebtedness of this Security or certain restrictive covenants and Events of
Default with respect to this Security, in each case upon compliance with certain
conditions set forth in the Indenture.

     If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture.

                                       5
<PAGE>

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of a majority in principal amount of the securities at
the time Outstanding of each series to be affected. The Indenture also contains
provisions permitting the Holders of specified percentages in principal amount
of the Securities of each series at the time Outstanding, on behalf of the
Holders of all Securities of such series, to waive compliance by the Company
with certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the Holder of
this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security issued upon the registration
of transfer hereof or in exchange herefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Security.

     As provided in and subject to the provisions of the Indenture, the Holder
of this Security shall not have the right to institute any proceeding with
respect to the Indenture or for the appointment of a receiver or trustee or for
any other remedy thereunder, unless such Holder shall have previously given the
Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of
Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee
shall not have received from the Holders of a majority in principal amount of
Securities of this series at the time Outstanding a direction inconsistent with
such request, and shall have failed to institute any such proceeding, for 60
days after receipt of such notice, request and offer of indemnity. The foregoing
shall not apply to any suit instituted by the Holder of this Security for the
enforcement of any payment of principal hereof or any premium or interest hereon
on or after the respective due dates expressed herein.

     No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and any premium and interest
on this Security at the times, place and rate, and in the coin or currency,
herein prescribed.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Security is registrable in the Security Register,
upon surrender of this Security for registration of transfer at the office or
agency of the Company in any place where the principal of and any premium and
interest on this Security are payable, duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Securities of this series
and of like tenor, of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

                                       6
<PAGE>

     The Securities of this series are issuable only in registered form without
coupons in denominations of $1,000 and any integral multiple thereof. As
provided in the Indenture and subject to certain limitations therein set forth,
Securities of this series are exchangeable for a like aggregate principal amount
of Securities of this series and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.

     No service charge shall be made for any such registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

     Prior to due presentment of this Security for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this Security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

     All terms used in this Security which are defined in the Indenture shall
have the meanings assigned to them in the Indenture.

Credit Suisse First Boston Corporation
Chase Securities Inc.
 As Representatives of the Several Initial Purchasers,
 c/o Credit Suisse First Boston Corporation
     Eleven Madison Avenue
     New York, New York 10010-3629

Dear Sirs:

     Northrop Grumman Corporation, a Delaware corporation (the "Company"),
proposes to issue and sell to the several initial purchasers named in Schedule I
hereto (collectively, the "Initial Purchasers"), upon the terms set forth in a
purchase agreement of even date herewith (the "Purchase Agreement"), U.S.
$750,000,000 aggregate principal amount of its 7 1/8% Series A Notes due 2011
(the "Notes") and U.S. $750,000,000 aggregate principal amount of its 7 3/4%
Series A Debentures due 2031 (the "Debentures," and together with the Notes, the
"Initial Securities").  Upon consummation of the Merger (as defined in the
Purchase Agreement), NNG, Inc., a Delaware corporation ("NNG"), and Litton
Industries, Inc., a Delaware corporation ("Litton"), will execute guarantees
(the "Guarantees") with respect to the Securities (as defined below) (each of
Litton and NNG, a "Guarantor" and, collectively, the "Guarantors").  The Initial
Securities will be issued pursuant to an Indenture, dated as of October 15, 1994
among the Company and The Chase Manhattan Bank, as trustee (the "Trustee"), as
supplemented by an Officers' Certificate dated as of February 22, 2001
(collectively, the "Indenture").  As an inducement to the Initial Purchasers to
enter into the Purchase Agreement, the Company agrees with the Initial
Purchasers (and the Guarantors who will, upon consummation of the Merger, become
parties hereto, will so agree as to their Guarantees of the Securities (as
defined below)), for the benefit of the Initial Purchasers and the holders of
the Securities (collectively the "Holders"), as

                                       1
<PAGE>

follows (references below to the "Company" shall be deemed to include the
Guarantors upon the date of the consummation of the Merger):

     1.  Registered Exchange Offer.  Unless not permitted by applicable law
(after the Company has complied with the ultimate paragraph of this Section 1),
the Company shall prepare and, not later than 120 days (such 120th day being a
"Filing Deadline") after the date on which the Initial Purchasers purchase the
Initial Securities pursuant to the Purchase Agreement (the "Closing Date"), file
with the Securities and Exchange Commission (the "Commission") a registration
statement (the "Exchange Offer Registration Statement") on an appropriate form
under the Securities Act of 1933, as amended (the "Securities Act"), with
respect to a proposed offer (the "Registered Exchange Offer") to the Holders of
Transfer Restricted Securities (as defined in Section 6 hereof), who are not
prohibited by any law or policy of the Commission from participating in the
Registered Exchange Offer, to issue and deliver to such Holders, in exchange for
the Initial Securities, a like aggregate principal amount of debt securities of
the Company issued under the Indenture, identical in all material respects to
the Initial Securities and registered under the Securities Act (the "Exchange
Securities," which term shall include the Guarantees thereof).  The Company
shall use its best efforts to (i) cause such Exchange Offer Registration
Statement to become effective under the Securities Act within 180 days after the
Closing Date (such 180th day being an "Effectiveness Deadline")  and (ii)  keep
the Exchange Offer Registration Statement effective for not less than 30 days
(or longer, if required by applicable law) after the date notice of the
Registered Exchange Offer is mailed to the Holders (such period being called the
"Exchange Offer Registration Period").  The date notice of the Registered
Exchange Offer is mailed to the Holders shall be called the "commencement" of
the Registered Exchange Offer.

     If the Company commences the Registered Exchange Offer, the Company (i)
will be entitled to consummate the Registered Exchange Offer 30 days after such
commencement (provided that the Company has accepted all the Initial Securities
theretofore validly tendered in accordance with the terms of the Registered
Exchange Offer) and (ii) will be required to consummate the Registered Exchange
Offer no later than 40 days after the date on which the Exchange Offer
Registration Statement is declared effective (such 40th day being the
"Consummation Deadline").

     Following the declaration of the effectiveness of the Exchange Offer
Registration Statement, the Company shall promptly commence the Registered
Exchange Offer, it being the objective of such Registered Exchange Offer to
enable each Holder of Transfer Restricted Securities electing to exchange the
Initial Securities for Exchange Securities (assuming that such Holder is not an
affiliate of the Company within the meaning of the Securities Act, acquires the
Exchange Securities in the ordinary course of such Holder's business and has no
arrangements with any person to participate in the distribution of the Exchange
Securities and is not prohibited by any law or policy of the Commission from
participating in the Registered Exchange Offer) to trade such Exchange
Securities from and after their receipt without any limitations or restrictions
under the Securities Act and

                                       2
<PAGE>

without material restrictions under the securities laws of the several states of
the United States.

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

     The Company shall use its best efforts to keep the Exchange Offer
Registration Statement effective and to amend and supplement the prospectus
contained therein, in order to permit such prospectus to be lawfully delivered
by all persons subject to the prospectus delivery requirements of the Securities
Act for such period of time as such persons must comply with such requirements
in order to resell the Exchange Securities; provided, however, that (i) in the
                                            --------  -------
case where such prospectus and any amendment or supplement thereto must be
delivered by an Exchanging Dealer or an Initial Purchaser, such period shall be
the lesser of 180 days and the date on which all Exchanging Dealers and the
Initial Purchasers have sold all Exchange Securities held by them (unless such
period is extended pursuant to Section 3(j) below or a Shelf Registration
Statement is applicable and useable) and (ii) the Company shall make such
prospectus and any amendment or supplement thereto available to any broker-
dealer for use in connection with any resale of any Exchange Securities for a
period of not less than 180 days after the consummation of the Registered
Exchange Offer (the "Expiration Date").

     If, upon consummation of the Registered Exchange Offer, any Initial
Purchaser holds Initial Securities acquired by it as part of its initial
distribution, the Company, simultaneously with the delivery of the Exchange
Securities pursuant to the Registered Exchange Offer, shall issue and deliver to
such Initial Purchaser upon the written request of such Initial Purchaser, in
exchange (the "Private Exchange") for the Initial Securities held by such
Initial Purchaser, a like principal amount of debt securities of the Company
issued under the Indenture and identical in all material respects to the Initial
Securities (the "Private Exchange Securities," which term shall include the
Guarantees thereof).  The Initial Securities, the Exchange Securities and the
Private Exchange Securities, and the Guarantees thereof, are herein collectively
called the "Securities."

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

                                       3
<PAGE>

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

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

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

          (d) permit Holders to withdraw tendered Initial Securities at any time
     prior to the close of business, New York time, on the last business day on
     which the Registered Exchange Offer shall remain open; and

          (e) otherwise comply with all applicable laws.

     As soon as practicable after the close of the Registered Exchange Offer or
the Private Exchange, as the case may be, the Company shall:

          (x) accept for exchange all the Initial Securities validly tendered
     and not withdrawn pursuant to the Registered Exchange Offer or the Private
     Exchange;

          (y) deliver to the Trustee for cancellation all the Initial Securities
     so accepted for exchange; and

          (z) cause the Trustee to authenticate and deliver promptly to each
     Holder of Initial Securities, Exchange Securities or Private Exchange
     Securities, as the case may be, equal in principal amount to the Initial
     Securities of such Holder so accepted for exchange.

     The Indenture provides that the Exchange Securities will not be subject to
the transfer restrictions set forth in the Indenture and that all the holders of
the Notes or the Debentures, as the case may be, will vote and consent together
on all matters as one class and that none of the holders of the Notes or the
Debentures, as the case may be, will have the right to vote or consent as a
class separate from one another on any matter.

     Interest on each Exchange Security and Private Exchange Security issued
pursuant to the Registered Exchange Offer or in the Private Exchange will accrue
from the last interest payment date on which interest was duly paid on the
Initial Securities surrendered in exchange therefor or, if no interest has been
paid on the Initial Securities, from the date of original issue of the Initial
Securities.  Holders whose Initial Securities are accepted for

                                       4

exchange will be deemed to have waived the right to receive any interest accrued
on such exchanged securities.

     Each Holder participating in the Registered Exchange Offer shall be
required to represent to the Company that at the time of the consummation of the
Registered Exchange Offer (i) any Exchange Securities 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 Initial Securities or the Exchange Securities within the
meaning of the Securities Act, (iii) such Holder is not an "affiliate," as
defined in Rule 405 of the Securities Act, of the Company or if it is an
affiliate, such Holder will comply with the registration and prospectus delivery
requirements of the Securities Act to the extent applicable, (iv) if such Holder
is not a broker-dealer, that it is not engaged in, and does not intend to engage
in, the distribution of the Exchange Securities and (v) if such Holder is a
broker-dealer, that it will receive Exchange Securities for its own account in
exchange for Initial Securities that were acquired as a result of market-making
activities or other trading activities and that it will deliver a prospectus in
connection with any resale of such Exchange Securities.

     Notwithstanding any other provisions hereof, the Company will ensure that
(i) any Exchange Offer Registration Statement and any amendment thereto and any
prospectus forming part thereof and any supplement thereto complies in all
material respects with the Securities Act and the rules and regulations
thereunder, (ii) any Exchange Offer Registration Statement and any amendment
thereto does not, when it becomes effective, contain an untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading and (iii) any prospectus
forming part of any Exchange Offer Registration Statement, and any supplement to
such prospectus, does not include an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

     If following the date hereof there has been announced a change in
Commission policy with respect to exchange offers that in the reasonable opinion
of counsel to the Company raises a substantial question as to whether the
Registered Exchange Offer is permitted by applicable federal law, the Company
will seek a no-action letter or other favorable decision from the Commission
allowing the Company to consummate the Registered Exchange Offer.  The Company
will pursue the issuance of such a decision to the Commission staff level.  In
connection with the foregoing, the Company will take all such other actions as
may be requested by the Commission or otherwise required in connection with the
issuance of such decision, including without limitation (i) participating in
telephonic conferences with the Commission, (ii) delivering to the Commission
staff an analysis prepared by counsel to the Company setting forth the legal
bases, if any, upon which such counsel has concluded that the Registered
Exchange Offer should be permitted and (iii) diligently pursuing a resolution
(which need not be favorable) by the Commission staff.

     2.  Shelf Registration.  If, (i) because of any change in law or in
applicable interpretations thereof by the staff of the Commission, the Company
is not permitted to effect a Registered Exchange Offer, as contemplated by
Section 1 hereof, (ii) the Registered Exchange Offer is not consummated by the
220th day after the Closing Date, (iii) any Initial Purchaser so requests within
20 business days following the consummation of the Registered Exchange Offer
with respect to the Initial Securities (or the Private Exchange Securities) not
eligible to be exchanged for Exchange Securities in the Registered Exchange
Offer and held by it following consummation of the Registered Exchange Offer or
(iv) any Holder is not eligible to participate in the Registered Exchange Offer
or, in the case of any Holder that participates in the Registered Exchange
Offer, such Holder does not receive freely tradeable Exchange Securities on the
date of the exchange and any such Holder so requests within 20 business days
following the consummation of the Registered Exchange Offer, the Company shall
take the following actions (the date on which any of the conditions described in
the foregoing clauses (i) through (iv) occur, including in the case of clauses
(iii) or (iv) the receipt of the required notice, being a "Trigger Date"):

          (a)  The Company shall promptly  (but in no event more than 30 days
     after the Trigger Date (such 30th day being a "Filing Deadline")) file with
     the Commission and thereafter use its best efforts to cause to be declared
     effective no later than 150 days after the Trigger Date (such 150th day
     being an "Effectiveness Deadline") a registration statement (the "Shelf
     Registration Statement" and, together with the Exchange Offer Registration
     Statement, a "Registration Statement") on an appropriate form under the
     Securities Act relating to the offer and sale of the Transfer Restricted
     Securities by the Holders thereof from time to time in accordance with the
     methods of distribution set forth in the Shelf Registration Statement and
     Rule 415 under the Securities Act (hereinafter, the "Shelf Registration");
     provided, however, that no Holder (other than an Initial Purchaser) shall
     --------  -------
     be entitled to have the Securities held by it covered by such Shelf
     Registration Statement unless such Holder agrees in writing to be bound by
     all the provisions of this Agreement applicable to such Holder.

          (b)  The Company shall use its best efforts to keep the Shelf
     Registration Statement continuously effective in order to permit the
     prospectus included therein to be lawfully delivered by the Holders of the
     relevant Securities, for a period of two years (or for such longer period
     if extended pursuant to Section 3(j) below) from the date of its
     effectiveness or such shorter period that will terminate when all the
     Securities covered by the Shelf Registration Statement (i) have been sold
     pursuant thereto or (ii) are saleable without registration under the
     Securities Act pursuant to Rule 144(k) or any successor statute (the "Shelf
     Registration  Period").  The Company shall be deemed not to have used its
     best efforts to keep the Shelf Registration Statement effective during the
     requisite period if it voluntarily takes any action that would result in
     Holders of Securities covered

                                       6
<PAGE>

     thereby not being able to offer and sell such Securities during that
     period, unless such action is required by applicable law.

          (c)  Notwithstanding any other provisions of this Agreement to the
     contrary, the Company shall cause the Shelf Registration Statement and the
     related prospectus and any amendment or supplement thereto, as of the
     effective date of the Shelf Registration Statement, amendment or
     supplement, (i) to comply in all material respects with the applicable
     requirements of the Securities Act and the rules and regulations of the
     Commission and (ii) not to contain any untrue statement of a material fact
     or omit to state a material fact required to be stated therein or necessary
     in order to make the statements therein, in light of the circumstances
     under which they were made, not misleading.

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

          (a)  The Company shall (i) furnish to each Initial Purchaser, prior to
     the filing thereof with the Commission, a copy of the Registration
     Statement and each amendment thereof and each supplement, if any, to the
     prospectus included therein and, in the event that an Initial Purchaser is
     participating in the Registered Exchange Offer or the Shelf Registration
     Statement, the Company shall use its best efforts to reflect in each such
     document, when so filed with the Commission, such comments as such Initial
     Purchaser reasonably may propose; (ii) include the information set forth in
     Annex A hereto on the cover, in Annex B hereto in the "Exchange Offer
     Procedures" section and the "Purpose of the Exchange Offer" section and in
     Annex C hereto in the "Plan of Distribution" section of the prospectus
     forming a part of the Exchange Offer Registration Statement and include the
     information set forth in Annex D hereto in the Letter of Transmittal
     delivered pursuant to the Registered Exchange Offer; (iii) if requested by
     an Initial Purchaser, include the information required by Items 507 or 508
     of Regulation S-K under the Securities Act, as applicable, in the
     prospectus forming a part of the Shelf Registration Statement; (iv) include
     within the prospectus contained in the Exchange Offer Registration
     Statement a section entitled "Plan of Distribution," reasonably acceptable
     to the Initial Purchasers, which shall contain a summary statement of the
     positions taken or policies made by the staff of the Commission with
     respect to the potential "underwriter" status of any broker-dealer that is
     the beneficial owner (as defined in Rule 13d-3 under the Securities
     Exchange Act of 1934, as amended (the "Exchange Act")) of Exchange
     Securities received by such broker-dealer in the Registered Exchange Offer
     (a "Participating Broker-Dealer"), whether such positions or policies have
     been publicly disseminated by the staff of the Commission or such positions
     or policies, in the reasonable judgment of the Initial Purchasers based
     upon advice of counsel (which may be in-house counsel), represent the
     prevailing views of the staff of the Commission; and (v) in the case of a
     Shelf Registration Statement, include the names of the

                                       7
<PAGE>

     Holders who propose to sell Securities pursuant to the Shelf Registration
     Statement as selling security holders.

          (b)  The Company shall give written notice to the Initial Purchasers,
     the Holders of the Securities included within the coverage of the
     Registration Statement and any Participating Broker-Dealer from whom the
     Company has received prior written notice that it will be a Participating
     Broker-Dealer in the Registered Exchange Offer (which notice pursuant to
     clauses (ii)-(v) hereof shall be accompanied by an instruction to suspend
     the use of the prospectus until the requisite changes have been made):

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

               (ii) of any request by the Commission for amendments or
          supplements to the Registration Statement or the prospectus included
          therein or for additional information;

               (iii) of the issuance by the Commission of any stop order
          suspending the effectiveness of the Registration Statement or the
          initiation of any proceedings for that purpose;

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

               (v) of the happening of any event that requires the Company to
          make changes in the Registration Statement or the prospectus in order
          that the Registration Statement or the prospectus do not contain an
          untrue statement of a material fact nor omit to state a material fact
          required to be stated therein or necessary to make the statements
          therein (in the case of the prospectus, in light of the circumstances
          under which they were made) not misleading.

          (c)  The Company shall make every reasonable effort to obtain the
     withdrawal at the earliest possible time, of any order suspending the
     effectiveness of the Registration Statement.

          (d)  The Company shall furnish to each Holder of Securities included
     within the coverage of the Shelf Registration, without charge, at least one
     copy of the Shelf Registration Statement and any post-effective amendment
     thereto, including financial statements and schedules, and, if the Holder
     so requests in writing, all exhibits thereto (including those, if any,
     incorporated by reference).

                                       8
<PAGE>

          (e)  The Company shall deliver to each Exchanging Dealer and each
     Initial Purchaser, and to any other Holder who so requests, without charge,
     at least one copy of the Exchange Offer Registration Statement and any
     post-effective amendment thereto, including financial statements and
     schedules, and, if any Initial Purchaser or any such Holder requests, all
     exhibits thereto (including those, if any, incorporated by reference).

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

          (g)  The Company shall deliver to each Initial Purchaser, any
     Exchanging Dealer, any Participating Broker-Dealer and such other persons
     required to deliver a prospectus following the Registered Exchange Offer,
     without charge, as many copies of the final prospectus included in the
     Exchange Offer Registration Statement and any amendment or supplement
     thereto as such persons may reasonably request.  The Company consents,
     subject to the provisions of this Agreement, to the use of the prospectus
     or any amendment or supplement thereto by any Initial Purchaser, if
     necessary, any Participating Broker-Dealer and such other persons required
     to deliver a prospectus following the Registered Exchange Offer in
     connection with the offering and sale of the Exchange Securities covered by
     the prospectus, or any amendment or supplement thereto, included in such
     Exchange Offer Registration Statement.

          (h)  Prior to any public offering of the Securities pursuant to any
     Registration Statement the Company shall register or qualify or cooperate
     with the Holders of the Securities included therein and their respective
     counsel in connection with the registration or qualification of the
     Securities for offer and sale under the securities or "blue sky" laws of
     such states of the United States as any Holder of the Securities reasonably
     requests in writing and do any and all other acts or things necessary or
     advisable to enable the offer and sale in such jurisdictions of the
     Securities covered by such Registration Statement; provided, however, that
                                                        --------  -------
     the Company shall not be required to (i) qualify generally to do business
     in any jurisdiction where it is not then so qualified or (ii) take any
     action which would subject it to general service of process or to taxation
     in any jurisdiction where it is not then so subject.

                                       9
<PAGE>

          (i)  The Company shall cooperate with the Holders of the Securities to
     facilitate the timely preparation and delivery of certificates representing
     the Securities to be sold pursuant to any Registration Statement free of
     any restrictive legends and in such denominations and registered in such
     names as the Holders may request a reasonable period of time prior to sales
     of the Securities pursuant to such Registration Statement.

          (j)  Upon the occurrence of any event contemplated by paragraphs (ii)
     through (v) of Section 3(b) above during the period for which the Company
     is required to maintain an effective Registration Statement, the Company
     shall promptly prepare and file a post-effective amendment to the
     Registration Statement or a supplement to the related prospectus and any
     other required document so that, as thereafter delivered to Holders of the
     Securities or purchasers of Securities, the prospectus will not contain an
     untrue statement of a material fact or omit to state any material fact
     required to be stated therein or necessary to make the statements therein,
     in light of the circumstances under which they were made, not misleading.
     If the Company notifies the Initial Purchasers, the Holders of the
     Securities and any known Participating Broker-Dealer in accordance with
     paragraphs (ii) through (v) of Section 3(b) above to suspend the use of the
     prospectus until the requisite changes to the prospectus have been made,
     then the Initial Purchasers, the Holders of the Securities and any such
     Participating Broker-Dealers shall suspend use of such prospectus, and the
     period of effectiveness of the Shelf Registration Statement provided for in
     Section 2(b) above and the Exchange Offer Registration Statement provided
     for in Section 1 above shall each be extended by the number of days from
     and including the date of the giving of such notice to and including the
     date when the Initial Purchasers, the Holders of the Securities and any
     known Participating Broker-Dealer shall have received such amended or
     supplemented prospectus pursuant to this Section 3(j).

          (k)  Not later than the effective date of the applicable Registration
     Statement, the Company will provide a CUSIP number for the Initial
     Securities, the Exchange Securities or the Private Exchange Securities, as
     the case may be, and provide the applicable trustee with printed
     certificates for the Initial Securities, the Exchange Securities or the
     Private Exchange Securities, as the case may be, in a form eligible for
     deposit with The Depository Trust Company.

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

                                       10
<PAGE>

     Company's first fiscal quarter commencing after the effective date of the
     Registration Statement, which statement shall cover such 12-month period.

          (m)  The Company shall cause the Indenture to be qualified under the
     Trust Indenture Act of 1939, as amended, in a timely manner and containing
     such changes, if any, as shall be necessary for such qualification.  In the
     event that such qualification would require the appointment of a new
     trustee under the Indenture, the Company shall appoint a new trustee
     thereunder pursuant to the applicable provisions of the Indenture.

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

          (o)  The Company shall enter into such customary agreements
     (including, if requested, an underwriting agreement in customary form) and
     take all such other action, if any, as any Holder of the Securities shall
     reasonably request in order to facilitate the disposition of the Securities
     pursuant to any Shelf Registration.

          (p)  In the case of any Shelf Registration, the Company shall (i) make
     reasonably available for inspection by the Holders of the Securities, any
     underwriter participating in any disposition pursuant to the Shelf
     Registration Statement and any attorney, accountant or other agent retained
     by the Holders of the Securities or any such underwriter all relevant
     financial and other records, pertinent corporate documents and properties
     of the Company and (ii) cause the Company's officers, directors, employees,
     accountants and auditors to supply all relevant information reasonably
     requested by the Holders of the Securities or any such underwriter,
     attorney, accountant or agent in connection with the Shelf Registration
     Statement, in each case, as shall be reasonably necessary to enable such
     persons, to conduct a reasonable investigation within the meaning of
     Section 11 of the Securities Act (collectively, "Company Information");
                                                      -------------------
     provided, however, that if the Company determines that any requested
     --------  -------
     Company Information is confidential, such Company Information shall not be
     disclosed unless the requesting party signs a confidentiality agreement in
     customary form and otherwise reasonably satisfactory to the Company (it
     being understood that such confidentiality agreement shall not include any
     "standstill" or similar contractual restriction on the purchase, sale or
     voting of securities of the Company unrelated to compliance with the anti-
     fraud provisions of the federal securities laws); and provided, further,
                                                           --------  -------
     that the Company shall not be obligated to disclose any Company Information
     that it is not legally permitted to disclose by operation

                                       11
<PAGE>

     of government regulation or similar requirement, including, without
     limitation, by operation of national security classification; and provided,
                                                                       --------
     further, that the foregoing inspection and information gathering shall be
     -------
     coordinated on behalf of the Initial Purchasers by you and on behalf of the
     other parties, by one counsel designated by and on behalf of such other
     parties as described in Section 4 hereof.

          (q)  In the case of any Shelf Registration, the Company, if requested
     by any Holder of Securities covered thereby, shall cause (i) its counsel to
     deliver an opinion and updates thereof relating to the Securities in
     customary form (which may include limitations and qualifications similar to
     those set forth in the opinion given by counsel to the Company pursuant to
     Section 6(d) of the Purchase Agreement) addressed to such Holders and the
     managing underwriters, if any, thereof and dated, in the case of the
     initial opinion, the effective date of such Shelf Registration Statement
     (it being agreed that the matters to be covered by such opinion shall
     include, without limitation, the due incorporation and good standing of the
     Company and its subsidiaries; the qualification of the Company and its
     subsidiaries to transact business as foreign corporations; the due
     authorization, execution and delivery of the relevant agreement of the type
     referred to in Section 3(o) hereof; the due authorization, execution,
     authentication and issuance, and the validity and enforceability, of the
     applicable Securities; the absence of material legal or governmental
     proceedings involving the Company and its subsidiaries; the absence of
     governmental approvals required to be obtained in connection with the Shelf
     Registration Statement, the offering and sale of the applicable Securities,
     or any agreement of the type referred to in Section 3(o) hereof; the
     compliance as to form of such Shelf Registration Statement and any
     documents incorporated by reference therein and of the Indenture with the
     requirements of the Securities Act and the Trust Indenture Act,
     respectively; and, as of the date of the opinion and as of the effective
     date of the Shelf Registration Statement or most recent post-effective
     amendment thereto, as the case may be, the absence from such Shelf
     Registration Statement and the prospectus included therein, as then amended
     or supplemented, and from any documents incorporated by reference therein
     of an untrue statement of a material fact or the omission to state therein
     a material fact required to be stated therein or necessary to make the
     statements therein not misleading (in the case of any such documents, in
     the light of the circumstances existing at the time that such documents
     were filed with the Commission under the Exchange Act)); (ii) its officers
     to execute and deliver all customary documents and certificates and updates
     thereof requested by any underwriters of the applicable Securities and
     (iii) its independent public accountants and the independent public
     accountants with respect to any other entity for which financial
     information is provided in the Shelf Registration Statement to provide to
     the selling Holders of the applicable Securities and any underwriter
     therefor a comfort letter in customary form and covering matters of the
     type customarily covered in comfort letters in connection with primary
     underwritten offerings, subject to receipt of appropriate documentation as
     contemplated, and only if permitted, by Statement of Auditing Standards No.

                                       12
<PAGE>

          (r)  In the case of the Registered Exchange Offer, if requested by any
     Initial Purchaser or any known Participating Broker-Dealer, the Company
     shall cause (i) its counsel to deliver to such Initial Purchaser or such
     Participating Broker-Dealer a signed opinion in the form set forth in
     Section 6(d) and (e) of the Purchase Agreement with such changes as are
     customary in connection with the preparation of a Registration Statement
     and (ii) its independent public accountants and the independent public
     accountants with respect to any other entity for which financial
     information is provided in the Registration Statement to deliver to such
     Initial Purchaser or such Participating Broker-Dealer a comfort letter, in
     customary form, meeting the requirements as to the substance thereof as set
     forth in Section 6(a) and (b) of the Purchase Agreement, with appropriate
     date changes.

          (s)   If a Registered Exchange Offer or a Private Exchange is to be
     consummated, upon delivery of the Initial Securities by Holders to the
     Company (or to such other Person as directed by the Company) in exchange
     for the Exchange Securities or the Private Exchange Securities, as the case
     may be, the Company shall mark, or cause to be marked, on the Initial
     Securities so exchanged that such Initial Securities are being canceled in
     exchange for the Exchange Securities or the Private Exchange Securities, as
     the case may be; in no event shall the Initial Securities be marked as paid
     or otherwise satisfied.

          (t)  The Company will use its best efforts to (a) if the Initial
     Securities have been rated prior to the initial sale of such Initial
     Securities, confirm such ratings will apply to the Securities covered by a
     Registration Statement, or (b) if the Initial Securities were not
     previously rated, cause the Securities covered by a Registration Statement
     to be rated with the appropriate rating agencies, if so requested by
     Holders of a majority in aggregate principal amount of Securities covered
     by such Registration Statement, or by the managing underwriters, if any.

          (u)  In the event that any broker-dealer registered under the Exchange
     Act shall underwrite any Securities or participate as a member of an
     underwriting syndicate or selling group or "assist in the distribution"
     (within the meaning of the Conduct Rules (the "Rules") of the National
     Association of Securities Dealers, Inc. ("NASD")) thereof, whether as a
     Holder of such Securities or as an underwriter, a placement or sales agent
     or a broker or dealer in respect thereof, or otherwise, the Company will
     assist such broker-dealer in complying with the requirements of such Rules,
     including, without limitation, by (i) if such Rules, including Rule 2720,
     shall so require, engaging a "qualified independent underwriter" (as
     defined in Rule 2720) to participate in the preparation of the Registration
     Statement relating to such Securities, to exercise usual standards of due
     diligence in respect thereto and, if any portion of the offering
     contemplated by such Registration Statement is an underwritten offering or
     is made through a placement or sales agent, to recommend the yield of such
     Securities, (ii) indemnifying any such qualified independent underwriter to
     the extent of the

                                       13
<PAGE>

     indemnification of underwriters provided in Section 5 hereof and (iii)
     providing such information to such broker-dealer as may be required in
     order for such broker-dealer to comply with the requirements of the Rules.

          (v)  The Company shall use its best efforts to take all other steps
     necessary to effect the registration of the Securities covered by a
     Registration Statement contemplated hereby.

     4.  Registration Expenses.  (a) All expenses incident to the Company's
performance of and compliance with this Agreement, other than underwriting
discounts and commissions of selling Holders, if any, will be borne by the
Company, regardless of whether a Registration Statement is ever filed or becomes
effective, including without limitation;

          (i)  all registration and filing fees and expenses;

          (ii) all fees and expenses of compliance with federal securities and
     state "blue sky" or securities laws;

          (iii) all expenses of printing (including printing certificates for
     the Securities to be issued in the Registered Exchange Offer and the
     Private Exchange and printing of prospectuses), messenger and delivery
     services and telephone;

          (iv) all fees and disbursements of counsel for the Company;

          (v) all application and filing fees in connection with listing the
     Exchange Securities on a national securities exchange or automated
     quotation system pursuant to the requirements hereof; and

          (vi) all fees and disbursements of independent certified public
     accountants of the Company (including the expenses of any special audit and
     comfort letters required by or incident to such performance).

The Company will bear its internal expenses (including, without limitation, all
salaries and expenses of its officers and employees performing legal or
accounting duties), the expenses of any annual audit and the fees and expenses
of any person, including special experts, retained by the Company.

     (b)  In connection with any Registration Statement required by this
Agreement, the Company will reimburse the Initial Purchasers and the Holders of
Transfer Restricted Securities who are tendering Initial Securities in the
Registered Exchange Offer and/or selling or reselling Securities pursuant to the
"Plan of Distribution" contained in the Exchange Offer Registration Statement or
the Shelf Registration Statement, as applicable, for the reasonable fees and
disbursements of not more than one counsel, who shall be Latham & Watkins, Los
Angeles unless another firm shall be chosen by the Holders of a

                                       14
<PAGE>

majority in principal amount of the Transfer Restricted Securities for whose
benefit such Registration Statement is being prepared.

     5.  Indemnification.  (a)  The Company agrees to indemnify and hold
harmless each Holder of the Securities, any Participating Broker-Dealer and each
person, if any, who controls such Holder or such Participating Broker-Dealer
within the meaning of the Securities Act or the Exchange Act (each Holder, any
Participating Broker-Dealer and such controlling persons are referred to
collectively as the "Indemnified Parties") from and against any losses, claims,
damages or liabilities, joint or several, or any actions in respect thereof
(including, but not limited to, any losses, claims, damages, liabilities or
actions relating to purchases and sales of the Securities) to which each
Indemnified Party may become subject under the Securities Act, the Exchange Act
or otherwise, insofar as such losses, claims, damages, liabilities or actions
arise out of or are based upon any untrue statement or alleged untrue statement
of a material fact contained in a Registration Statement or prospectus or in any
amendment or supplement thereto or in any preliminary prospectus relating to a
Shelf Registration, or arise out of, or are based upon, the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and shall reimburse, as
incurred, the Indemnified Parties for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability or action in respect thereof; provided, however, that
                                                       --------  -------
(i) the Company shall not be liable in any such case to the extent that such
loss, claim, damage or liability arises out of or is based upon any untrue
statement or alleged untrue statement or omission or alleged omission made in a
Registration Statement or prospectus or in any amendment or supplement thereto
or in any preliminary prospectus relating to a Shelf Registration in reliance
upon and in conformity with written information pertaining to such Holder and
furnished to the Company by or on behalf of such Holder specifically for
inclusion therein and (ii) with respect to any untrue statement or omission or
alleged untrue statement or omission made in any preliminary prospectus relating
to a Shelf Registration Statement, the indemnity agreement contained in this
subsection (a) shall not inure to the benefit of any Holder or Participating
Broker-Dealer from whom the person asserting any such losses, claims, damages or
liabilities purchased the Securities concerned, to the extent that a prospectus
relating to such Securities was required to be delivered by such Holder or
Participating Broker-Dealer under the Securities Act in connection with such
purchase and any such loss, claim, damage or liability of such Holder or
Participating Broker-Dealer results from the fact that there was not sent or
given to such person, at or prior to the written confirmation of the sale of
such Securities to such person, a copy of the final prospectus if the Company
had previously furnished copies thereof to such Holder or Participating Broker-
Dealer; provided further, however, that this indemnity agreement will be in
        -------- -------  -------
addition to any liability which the Company may otherwise have to such
Indemnified Party.  The Company shall also indemnify underwriters, their
officers and directors and each person who controls such underwriters within the
meaning of the Securities Act or the Exchange Act to the same extent as provided
above with respect to the indemnification of the Holders of the Securities if
requested by such Holders.

                                       15
<PAGE>

     (b)  Each Holder of the Securities, severally and not jointly, will
indemnify and hold harmless the Company and each person, if any, who controls
the Company within the meaning of the Securities Act or the Exchange Act from
and against any losses, claims, damages or liabilities or any actions in respect
thereof, to which the Company or any such controlling person may become subject
under the Securities Act, the Exchange Act or otherwise, insofar as such losses,
claims, damages, liabilities or actions arise out of or are based upon any
untrue statement or alleged untrue statement of a material fact contained in a
Registration Statement or prospectus or in any amendment or supplement thereto
or in any preliminary prospectus relating to a Shelf Registration, or arise out
of or are based upon the omission or alleged omission to state therein a
material fact necessary to make the statements therein not misleading, but in
each case only to the extent that the untrue statement or omission or alleged
untrue statement or omission was made in reliance upon and in conformity with
written information pertaining to such Holder and furnished to the Company by or
on behalf of such Holder specifically for inclusion therein; and, subject to the
limitation set forth immediately preceding this clause, shall reimburse, as
incurred, the Company for any legal or other expenses reasonably incurred by the
Company or any such controlling person in connection with investigating or
defending any loss, claim, damage, liability or action in respect thereof.  This
indemnity agreement will be in addition to any liability which such Holder may
otherwise have to the Company or any of its controlling persons.

     (c)  Promptly after receipt by an indemnified party under this Section 5 of
notice of the commencement of any action or proceeding (including a governmental
investigation), such indemnified party will, if a claim in respect thereof is to
be made against the indemnifying party under this Section 5, notify the
indemnifying party of the commencement thereof; but the omission so to notify
the indemnifying party will not, in any event, relieve the indemnifying party
from any obligations to any indemnified party other than the indemnification
obligation provided in paragraph (a) or (b) above.  In case any such action is
brought against any indemnified party, and it notifies the indemnifying party of
the commencement thereof, the indemnifying party will be entitled to participate
therein and, to the extent that it may wish, jointly with any other indemnifying
party similarly notified, to assume the defense thereof, with counsel reasonably
satisfactory to such indemnified party (who shall not, except with the consent
of the indemnified party, be counsel to the indemnifying party), and after
notice from the indemnifying party to such indemnified party of its election so
to assume the defense thereof the indemnifying party will not be liable to such
indemnified party under this Section 5 for any legal or other expenses, other
than reasonable costs of investigation, subsequently incurred by such
indemnified party in connection with the defense thereof.  No indemnifying party
shall, without the prior written consent of the indemnified party, effect any
settlement of any pending or threatened action in respect of which any
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party unless such settlement includes an
unconditional release of such indemnified party from all liability on any claims
that are the subject matter of such action, and does not include a statement as
to or an admission of fault, culpability or a failure to act by or on behalf of
any indemnified party.

                                       16
<PAGE>

     (d)  If the indemnification provided for in this Section 5 is unavailable
or insufficient to hold harmless an indemnified party under subsections (a) or
(b) above, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of the losses, claims, damages or
liabilities (or actions in respect thereof) referred to in subsection (a) or (b)
above (i) in such proportion as is appropriate to reflect the relative benefits
received by the indemnifying party or parties on the one hand and the
indemnified party on the other from the sale of the Securities, or (ii) if the
allocation provided by the foregoing clause (i) is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative
benefits referred to in clause (i) above but also the relative fault of the
indemnifying party or parties on the one hand and the indemnified party on the
other in connection with the statements or omissions that resulted in such
losses, claims, damages or liabilities (or actions in respect thereof) as well
as any other relevant equitable considerations.  The relative fault of the
parties shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
on the one hand or such Holder or such other indemnified party, as the case may
be, on the other, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The amount paid by an indemnified party as a result of the losses, claims,
damages or liabilities referred to in the first sentence of this subsection (d)
shall be deemed to include any legal or other expenses reasonably incurred by
such indemnified party in connection with investigating or defending any action
or claim which is the subject of this subsection (d).  Notwithstanding any other
provision of this Section 5(d), the Holders of the Securities shall not be
required to contribute any amount in excess of the amount by which the net
proceeds received by such Holders from the sale of the Securities pursuant to a
Registration Statement exceeds the amount of damages which such Holders have
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 Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.  For purposes of this paragraph (d), each person,
if any, who controls such indemnified party within the meaning of the Securities
Act or the Exchange Act shall have the same rights to contribution as such
indemnified party and each person, if any, who controls the Company within the
meaning of the Securities Act or the Exchange Act shall have the same rights to
contribution as the Company.

     (e)  The agreements contained in this Section 5 shall survive the sale of
the Securities pursuant to a Registration Statement and shall remain in full
force and effect, regardless of any termination or cancellation of this
Agreement or any investigation made by or on behalf of any indemnified party.

     6.  Additional Interest Under Certain Circumstances.  (a)  Additional
interest (the "Additional Interest") with respect to the Securities shall be
assessed as follows if any

                                       17
<PAGE>

of the following events occur (each such event in clauses (i) through (iv) below
being herein called a "Non-Registration Event"):

     (i)  any Registration Statement required by this Agreement is not filed
          with the Commission on or prior to the applicable Filing Deadline;

     (ii) any Registration Statement required by this Agreement is  not declared
          effective by the Commission on or prior to the applicable
          Effectiveness Deadline;

    (iii) the Registered Exchange Offer has not been consummated on or prior
          to the Consummation Deadline; or

     (iv) except as provided in Section 6(b) below, any Registration Statement
          required by this Agreement has been declared effective by the
          Commission but (A) such Registration Statement thereafter ceases to be
          effective or (B) such Registration Statement or the related prospectus
          ceases to be usable in connection with resales of Transfer Restricted
          Securities during the periods specified herein because either (1) any
          event occurs as a result of which the related prospectus forming part
          of such Registration Statement would include any untrue statement of a
          material fact or omit to state any material fact necessary to make the
          statements therein in the light of the circumstances under which they
          were made not misleading, or (2) it shall be necessary to amend such
          Registration Statement or supplement the related prospectus, to comply
          with the Securities Act or the Exchange Act or the respective rules
          thereunder.

Each of the foregoing will constitute a Non-Registration Event whatever the
reason for any such event and whether it is voluntary or involuntary or is
beyond the control of the Company or pursuant to operation of law or as a result
of any action or inaction by the Commission.

     Additional Interest shall accrue on the Securities over and above the
interest set forth in the title of the Securities from and including the date on
which any such Non-Registration Event shall occur to but excluding the date on
which all such Non-Registration Events have been cured, at a rate of 0.25% per
annum (the "Additional Interest Rate") for the first 90-day period immediately
following the occurrence of such Non-Registration Event.  The Additional
Interest Rate shall increase by an additional 0.25% per annum with respect to
each subsequent 90-day period until all Non-Registration Events have been cured,
up to a maximum Additional Interest Rate of 1.0% per annum.

     (b)  A Non-Registration Event referred to in Section 6(a)(iv) hereof shall
be deemed not to have occurred and be continuing in relation to a Shelf
Registration Statement or the related prospectus if (i) such Non-Registration
Event has occurred solely

                                       18
<PAGE>

as a result of (x) the filing of a post-effective amendment to such Shelf
Registration Statement to incorporate annual audited financial information with
respect to the Company where such post-effective amendment is not yet effective
and needs to be declared effective to permit Holders to use the related
prospectus or (y) other material events, with respect to the Company that would
need to be described in such Shelf Registration Statement or the related
prospectus and (ii) in the case of clause (y), the Company is proceeding
promptly and in good faith to amend or supplement such Shelf Registration
Statement and related prospectus to describe such events; provided, however,
                                                          --------  -------
that in any case if such Non-Registration Event occurs for a continuous period
in excess of 30 days, Additional Interest shall be payable in accordance with
the above paragraph from the day such Non-Registration Event occurs until such
Non-Registration Event is cured.

     (c)  Any amounts of Additional Interest due pursuant to Section 6(a) will
be payable in cash on the regular interest payment dates with respect to the
Securities.  The amount of Additional Interest will be determined by multiplying
the applicable Additional Interest Rate by the principal amount of the
Securities and further multiplied by a fraction, the numerator of which is the
number of days such Additional Interest Rate was applicable during such period
(determined on the basis of a 360-day year comprised of twelve 30-day months),
and the denominator of which is 360.

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

     7.  Rules 144 and 144A.  The Company shall use its best efforts to file the
reports required to be filed by it under the Securities Act and the Exchange Act
in a timely manner and, if at any time the Company is not required to file such
reports, it will, upon the request of any Holder of Securities, make publicly
available other information so long as necessary to permit sales of their
securities pursuant to Rules 144 and 144A.  The Company covenants that it will
take such further action as any Holder of Securities may reasonably request, all
to the extent required from time to time to enable such Holder to sell
Securities without registration under the Securities Act within the limitation
of the exemptions provided by Rules 144 and 144A (including the requirements of
Rule 144A(d)(4)).  The Company will provide a copy of this Agreement to
prospective purchasers of Initial Securities identified to the Company by the
Initial Purchasers upon request.  Upon the request of any Holder of Initial
Securities, the Company shall deliver

                                       19
<PAGE>

to such Holder a written statement as to whether it has complied with such
requirements. Notwithstanding the foregoing, nothing in this Section 7 shall be
deemed to require the Company to register any of its securities pursuant to the
Exchange Act.

     8.  Underwritten Registrations.  If any of the Transfer Restricted
Securities covered by any Shelf Registration are to be sold in an underwritten
offering, the investment banker or investment bankers and manager or managers
that will administer the offering ("Managing Underwriters") will be selected by
the Holders of a majority in aggregate principal amount of such Transfer
Restricted Securities to be included in such offering.

     No person may participate in any underwritten registration hereunder unless
such person (i) agrees to sell such person's Transfer Restricted Securities on
the basis reasonably provided in any underwriting arrangements approved by the
persons entitled hereunder to approve such arrangements and (ii) completes and
executes all questionnaires, powers of attorney, indemnities, underwriting
agreements and other documents reasonably required under the terms of such
underwriting arrangements.

     9.  Miscellaneous.

     (a)  Remedies.  The Company acknowledges and agrees that any failure by the
Company to comply with its obligations under Section 1 and 2 hereof may result
in material irreparable injury to the Initial Purchasers 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, the Initial Purchasers or any Holder may obtain such relief as may be
required to specifically enforce the Company's obligations under Sections 1 and
2 hereof.  The Company further agrees to waive the defense in any action for
specific performance that a remedy at law would be adequate.

     (b)  No Inconsistent Agreements.  The Company will not on or after the date
of this Agreement enter into any agreement with respect to its securities that
is inconsistent with the rights granted to the Holders 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 securities under any
agreement in effect on the date hereof.

     (c)  Amendments and Waivers.  The provisions of this Agreement with respect
to any series of Securities may not be amended, modified or supplemented, and
waivers or consents to departures from the provisions hereof may not be given,
except by the Company and the written consent of the Holders of a majority in
principal amount of the series of Securities affected by such amendment,
modification, supplement, waiver or consents.

in every other respect and of the remaining provisions contained herein shall
not be affected or impaired thereby.

     (k)  Securities Held by the Company.  Whenever the consent or approval of
Holders of a specified percentage of principal amount of Securities is required
hereunder, Securities held by the Company or its Affiliates (other than
subsequent Holders of Securities if such subsequent Holders are deemed to be
Affiliates solely by reason of their

                                       22
<PAGE>

holdings of such Securities) shall not be counted in determining whether such

     (l)  Agent for Service; Submission to Jurisdiction; Waiver of Immunities.
By the execution and delivery of this Agreement, the Company (i) acknowledges

agent upon which process may be served in any suit or proceeding arising out of
or relating to this Agreement that may be instituted in any federal or state
court in the State of New York or brought under federal or state securities
laws, and acknowledges that CT Corporation System has accepted such designation,
(ii) submits to the nonexclusive jurisdiction of any such court in any such suit
or proceeding, and (iii) agrees that service of process upon CT Corporation
System and written notice of said service to the Company shall be deemed in
every respect effective service of process upon it in any such suit or
proceeding.  The Company further agrees to take any and all action, including
the execution and filing of any and all such documents and instruments, as may
be necessary to continue such designation and appointment of CT Corporation
System in full force and effect so long as any of the Securities shall be
outstanding.  To the extent that the Company may acquire any immunity from
jurisdiction of any court or from any legal process (whether through service of
notice, attachment prior to judgment, attachment in aid of execution, execution
or otherwise) with respect to itself or its property, it hereby irrevocably
waives such immunity in respect of this Agreement, to the fullest extent
permitted by law.

     (m)  No Interpretation Against Drafter.   This Agreement is the product of
negotiations between the parties hereto represented by counsel and such parties
agree that no rule of construction relating to interpretation against the

                                                            ANNEX A

   Each broker-dealer that receives Exchange Securities for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Securities.  The
Letter of Transmittal states that by so acknowledging and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.  This Prospectus, as it
may be amended or supplemented from time to time, may be used by a broker-dealer
in connection with resales of Exchange Securities received in exchange for
Initial Securities where such Initial Securities were acquired by such broker-
dealer as a result of market-making activities or other trading activities.  The
Company has agreed that, for a period of 180 days after the Expiration Date (as
defined herein), it will make this Prospectus available to any broker-dealer for
use in connection with any such resale.  See "Plan of Distribution."

                                                            ANNEX B

   Each broker-dealer that receives Exchange Securities for its own account in
exchange for Initial Securities, where such Initial Securities were acquired by
such broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such Exchange Securities.  See "Plan of Distribution."

                                                            ANNEX C

                              PLAN OF DISTRIBUTION

   Each broker-dealer that receives Exchange Securities for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Securities.  This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of Exchange Securities received in
exchange for Initial Securities where such Initial Securities were acquired as a
result of market-making activities or other trading activities.  The Company has
agreed that, for a period of 180 days after the Expiration Date, it will make
this prospectus, as amended or supplemented, available to any broker-dealer for
use in connection with any such resale.  In addition, until _______________,
2001, all dealers effecting transactions in the Exchange Securities may be
required to deliver a prospectus./(1)/

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

appear on the back cover page of the Exchange Offer prospectus.

   For a period of 180 days after the Expiration Date the Company will promptly
send additional copies of this Prospectus and any amendment or supplement to
this Prospectus to any broker-dealer that requests such documents in the Letter
of Transmittal.  The Company has agreed to pay all expenses incident to the
Exchange Offer (including the expenses of one counsel for the Holders of the
Securities) other than commissions or concessions of any brokers or dealers and
will indemnify the Holders of the Securities (including any broker-dealers)
against certain liabilities, including liabilities under the Securities Act.
