June 25,
2003 


Credit
Suisse First Boston LLC

Eleven Madison Avenue

New York, New York 10010-3629 


Dear
Sirs: 


        MSW
Energy Holdings LLC, a Delaware limited liability company ("MSW Energy"), and MSW Energy Finance Co., Inc., a Delaware
corporation ("MSW Finance" and, together with MSW Energy, the "Issuers") propose to issue and sell to
Credit Suisse First Boston LLC (the "Initial Purchaser"), upon the terms set forth in a purchase agreement, dated as of June 11, 2003 (the
"Purchase Agreement"), $200,000,000 aggregate principal amount of its 81/2% Senior Secured Notes due 2010 (the
"Initial Securities") to be guaranteed by Duke Energy Hudson LLC (the "Guarantor"), upon its acquisition
by MSW (collectively with the Issuers, the "Company"). The Initial Securities will be issued pursuant to an Indenture, dated as of June 25, 2003
(the "Indenture"), among the Issuers, the Guarantor and Wells Fargo Bank Minnesota, National Association, as trustee (the
"Trustee"). As an inducement to the Initial Purchaser to enter into the Purchase Agreement, the Company agrees with the Initial Purchaser, for the
benefit of the Initial Purchaser and the holders of the Securities (as defined below) (collectively the "Holders"), as follows: 


        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 90 days (such 90th day being a "Filing Deadline")
after the date on which the Initial Purchaser purchases 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"). The Company shall use its commercially reasonable 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"). 


        If
the Company commences the Registered Exchange Offer, the Company (i) will be entitled to consummate the Registered Exchange Offer 30 business 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 30 business days after the date on which the Exchange Offer Registration Statement is declared effective (such 30th business day being the
"Consummation Deadline"). 





 



        Following
the declaration of the effectiveness of the Exchange Offer Registration Statement, the Company shall as soon as practicable 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 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) if the
Initial Purchaser elects to sell Securities (as defined below) acquired in exchange for Initial Securities constituting any portion of an unsold allotment, the Initial Purchaser 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 commercially reasonable 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 the Initial Purchaser, such period shall be the lesser of 180 days and the date on which all Exchanging Dealers and
the Initial Purchaser have sold all Exchange Securities held by them (unless such period is extended pursuant to Section 3(j) below) 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; provided further, that during such period the Company may suspend the availability of the Exchange Offer Registration Statement, without being required to pay any
Additional Interest, upon written notice to the Initial Purchaser, the Holders of Transfer Restricted Securities and each Exchanging Dealer (which notice shall be accompanied by an instruction to
suspend the use of any prospectus), for 60 days in any calendar year (each such period, a "Suspension Period") if there is a possible
acquisition, business combination, other similar transaction, business development, or event involving the Company that would require the disclosure thereof in the Exchange Offer Registration
Statement and the Company reasonably determines in the exercise of its good faith judgment that such disclosure, at such time, would have a material adverse effect on the business, operations or
prospects of the Company; provided that such written notice will be sufficient if it only refers to this paragraph and provides notice that a Suspension Period has occurred and instructs the recipient
not to use any prospectus until further notice. 


        If,
upon consummation of the Registered Exchange Offer, the 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 the 


2





 

Initial
Purchaser upon the written request of the Initial Purchaser, in exchange (the "Private Exchange") for the Initial Securities held by the 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"). The Initial Securities, the Exchange Securities and the Private Exchange Securities are herein collectively called the
"Securities". 


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



        (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, provided that the Company shall only be required to mail such prospectus to Holders of which it is aware after due inquiry; 


        (b)   keep
the Registered Exchange Offer open for not less than 30 days (or longer, if required by applicable law) after the date on which the Exchange Offer
Registration Statement was declared effective by the Commission; 



        (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 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 in all material respects 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 and 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 the Initial Securities, either 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 will provide that the Exchange Securities will not be subject to the transfer restrictions set forth in the Indenture and that all the Securities will vote and consent
together on all matters as one class and that none of the Securities 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 and in the Private Exchange will accrue from the last interest payment
date on which interest was 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. 


        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 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 


3





 



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 be required to acknowledge 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) the Company is not required to file the Exchange Offer Registration
Statement, (ii) 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, (iii) the Initial Purchaser so requests 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 the consummation of the Registered Exchange Offer or (iv) (a)(1) any Holder is prohibited by applicable law
or Commission policy from participating in the Registered Exchange Offer, (2) any Holder receives Exchange Securities in the Registered Exchange Offer which may not be resold to the public
without delivering a prospectus and the prospectus contained in the Exchange Offer Registration Statement is not appropriate or available for such resales or (3) in the case of any Holder that
is a broker-dealer and owns Securities acquired directly from the Issuers or an affiliate of the Issuers and (b) any such Holder so notifies the Issuers prior to the 20thday
following the Consummation Deadline), 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 clause (iv) the receipt of the required notice, being a "Trigger Date"): 



        (a)   The
Company shall promptly (but in no event more than 90 days after the Trigger Date (such 90th day being a "Filing
Deadline")) file with the Commission and thereafter use its commercially reasonable best efforts to cause to be declared effective no later than 180 days after the
Trigger Date (such 180th 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 



4





 

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 the 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 commercially reasonable 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 no longer
restricted securities (as defined in Rule 144 under the Securities Act, or any successor rule thereof)(such applicable period being herein referred to as the "Shelf
Registration Period"); provided, however, that during such time the Shelf Registration Statement is required to be effective, the Company may institute a Suspension Period
regarding the availability of the Shelf Registration Statement and the related prospectus, without being required to pay any Additional Interest, upon written notice to the Initial Purchaser, the
Holders of Transfer Restricted Securities and each Participating Broker-Dealer (which notice shall be accompanied by an instruction to suspend the use of any prospectus), if there is a possible
acquisition, business combination, other similar transaction, business development, or event involving the Company that would require the disclosure thereof in the Registration Statement and the
Company reasonably determines in the exercise of its good faith judgment that such disclosure, at such time, would have a material adverse effect on the business, operations or prospects of the
Company; provided that such written notice will be sufficient if it only refers to this paragraph and provides notice that a Suspension Period has occurred and instructs the recipient not to use any
prospectus until further notice. 


        (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 the 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 the Initial Purchaser, as reasonably requested, 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; (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;

Distribution," reasonably acceptable to the Initial Purchaser, 



5





 

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 Purchaser 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 Holders who propose to sell Securities pursuant to the Shelf Registration
Statement as selling securityholders. 


        (b)   The
Company shall give written notice to the Initial Purchaser, the Holders of the Securities 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 written notice pursuant to clauses (ii)-(vi) hereof shall be accompanied by an
instruction to suspend the use of the prospectus until the requisite changes, if any, 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, if known, any threatening of any proceeding for such purpose; 



         (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 the light of the circumstances under which they were made) not misleading; and 


        (vi)  of
any Suspension Period. 




        (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). 


        (e)   The
Company shall deliver to each Exchanging Dealer and the 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 the Initial Purchaser or any such Holder requests, all exhibits
thereto (including those incorporated by reference). 



6











  



        (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, in accordance with applicable law, 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 the 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, in accordance with applicable
law, by the 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 use its commercially reasonable best efforts to register or
qualify or cooperate with the Holders of the Securities included therein and their respective counsel in connection with the registration or qualification of the Securities for offer and sale under
the securities or "blue sky" 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 reasonably 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. 



        (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 (vi) of Section 3(b) above during the period for which the Company is required to
maintain an effective Registration Statement, the Company shall, if updating the information in the prospectus is required, 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 Purchaser, the Holders of the Securities and any known Participating Broker-Dealer in accordance with
paragraphs (ii) through (vi) of Section 3(b) above to suspend the use of the prospectus until the requisite changes to the prospectus have been made or until the end of any Suspension
Period, then the Initial Purchaser, 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 



7





 




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 Purchaser, the Holders of the Securities and any known
Participating Broker-Dealer shall have received an 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 or typewritten 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 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 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, subject to the execution of customary confidentiality agreements, the Company shall (i) make reasonably available at
reasonable times and upon reasonable notice 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; provided, however, that the foregoing inspection and information gathering
pursuant to clauses (i) and (ii) above shall be coordinated on behalf of the Initial Purchaser 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(b) hereof. 



8





 




        (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 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, which opinion shall cover matters customary for underwritten offerings of debt securities of companies similar to the Company; (ii) its officers to
execute and deliver all customary documents and certificates and updates thereof reasonably 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. 72., Letters for
Underwriters and Certain Other Requesting Parties, as amended by Statements on Auditing Standards No. 76 and No. 86. 


        (r)   In
the case of the Registered Exchange Offer, if requested by the Initial Purchaser or any known Participating Broker-Dealer, the Company shall cause (i) its
counsel to deliver to the Initial Purchaser or such Participating Broker-Dealer a signed opinion delivered pursuant to Section 6(c) 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 the 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 (j) 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 caused 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)    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 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. 



        (u)   The
Company shall use its commercially reasonable 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 any underwriting discounts and commissions in an underwritten offering in connection with any Shelf Registration) will be borne by the Company, regardless of whether a
Registration Statement is ever filed or becomes effective, including without limitation; 




          (i)  all
reasonable 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 Purchaser 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 not to exceed $25,000 of not more than one counsel, who shall be Latham &
Watkins LLP unless another firm shall be chosen by the Holders of a 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 or any of its officers and directors 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 


10





 

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 or Participating Broker-Dealer, as the case may be, and furnished to the Company by or on behalf of such Holder or Participating Broker-Dealer, as the case may
be, specifically for inclusion therein, (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 and (iii) the Company shall not, in connection with any one action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to any local counsel)
for all indemnified parties, such firm to be designated in writing by and on behalf of Holders as described in Section 4 hereof; 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 (and subject to the same
exceptions) as provided above with respect to the indemnification of the Holders of the Securities if requested by such Holders or Participating Broker-Dealers. 



        (b)   Each
Holder of the Securities and each Participating Broker-Dealer, severally and not jointly, will indemnify and hold harmless the Company and its officers and
directors 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 or Participating Broker-Dealer, as the case may be, and furnished to the Company by
or on behalf of such Holder or Participating Broker-Dealer, as the case may be, 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 its officers and directors 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 and each Participating Broker-Dealer, as the
case may be, 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 



11





 




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 indemnified 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 (which consent shall not be unreasonably withheld), 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. 


        (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 exchange of the Securities, pursuant to the Registered Exchange Offer, 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 



12





 




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 of the following events occur (each such event in
clauses (i) through (v) below being herein called a "Registration Default"): 




          (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; 


        (iv)  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; or 


         (v)  after
the 60th day in any calendar year of any Suspension Period, the suspension referred to in Sections 1 or 2 has not been terminated. 




Each
of the foregoing will constitute a Registration Default 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 Registration Default
shall occur to but excluding the date on which all such Registration Defaults have been cured, in the form of an increase in the annual interest rate borne by the Securities, at a rate of 0.25% per
annum (the "Additional Interest Rate") for the first 90-day period immediately following the occurrence of such Registration Default. The
Additional Interest Rate shall increase by an additional 0.25% per annum with respect to each subsequent 90-day period until all Registration Defaults have been cured, up to a maximum
Additional Interest Rate of 1.0% per annum. 


        (b)   A
Registration Default 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 Registration Default has occurred solely as a result of (x) the filing of a post-effective amendment to such Shelf Registration
Statement to incorporate annual audited financial information with respect to the Company 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 



13





 




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 Registration Default 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 Registration Default occurs until such Registration Default 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 under the Securities Act. 




        7.    Rules 144 and 144A.    The Company shall use its commercially reasonable 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 Purchaser upon request. If the Company ceases to be a
reporting company under the Exchange Act, upon the request of any Holder of Initial Securities, the Company shall deliver 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, which
Managing Underwriter shall be reasonably acceptable to the Company. 


        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. 


14







   
        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 Purchaser 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 Purchaser 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 may not be amended, modified or supplemented, and
waivers or consents to departures from the provisions hereof may not be given, except by the Company and the written consent of the Holders of a majority in principal amount of the Securities affected
by such amendment, modification, supplement, waiver or consents. 



        (d)    Notices.    All notices and other communications provided for or permitted hereunder shall be made in writing
by hand delivery, first-class mail, facsimile transmission, or air courier which guarantees overnight delivery: 



        (1)   if
to a Holder of the Securities, at the most current address given by such Holder to the Company.

        (e)    Third Party Beneficiaries.    The Holders shall be third party beneficiaries to the agreements made hereunder
between the Company, on the one hand, and the Initial Purchaser, on the other hand, and shall have the right to enforce such agreements directly to the extent they may deem such enforcement necessary
or advisable to protect their rights or the rights of Holders hereunder. If any transferee or any Holder shall acquire any Transfer Restricted Securities in any manner, whether by operation of law or
otherwise, such Transfer Restricted Securities shall be held subject to all of the terms of this Agreement, and by acquiring and holding such Transfer Restricted Securities, such transferee shall be
conclusively deemed to have agreed to be bound by all of the terms and provisions of this Agreement, including the restrictions on resale set forth in this Agreement. 


        (f)    Successors and Assigns.    This Agreement shall be binding upon the Company and its successors and assigns.

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 WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAWS. 



        (j)    Severability.    If any one or more of the provisions contained herein, or the application thereof in any
circumstance, is held invalid, illegal or unenforceable, the validity, legality and enforceability of any such provision in every other respect and of the remaining provisions contained herein 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 holdings of such Securities) shall not be counted in determining whether such consent or approval was given by the Holders of such required percentage. 


        (l)    Guarantor.    Immediately after the closing of the Acquisition, the Company will cause the Guarantor to become
a party to this Agreement by causing the Guarantor to execute and deliver a signature page to this Agreement to the Initial Purchaser on the closing of the Acquisition; it being acknowledged and
agreed that all representations and warranties made by or with respect to the Guarantor and all covenants of the Guarantor shall not be effective unless and until the Guarantor executes and delivers a
signature page to this Agreement.

        If
the foregoing is in accordance with your understanding of our agreement, please sign and return to the Company a counterpart hereof, whereupon this instrument, along with all
counterparts, will become a binding agreement among the Initial Purchaser, the Issuers and the Guarantor in accordance with its terms.

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                        , 2003 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. 


        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. 




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