 The Offered Securities will be unconditionally guaranteed (the “Subsidiary Guarantees”) on a senior secured

any time offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any securities under circumstances where such offer, sale, pledge, contract or disposition would cause the exemption afforded by Section 4(2) of the
Securities Act or the safe harbor of Regulation S thereunder to cease to be applicable to the offer and sale of the Offered Securities. 
  
 (j) The Issuers will apply the net proceeds from the sale of the Offered Securities as set forth under “Use of Proceeds” in the

 (iii) on the basis of the
review referred to in clause (ii) above, a reading of the latest available interim financial statements of the Company, inquiries of officials of the Company who have responsibility for financial and accounting matters and other specified

involving the United States, any declaration of war by Congress or any other national or international calamity or emergency if, in the judgment of the Purchasers, the effect of any such attack, outbreak, escalation, act, declaration, calamity or
emergency makes it impractical or inadvisable to proceed with completion of the offering or sale of and payment for the Offered Securities.

joint or several, to which such Purchaser may become subject, under the Securities Act or the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue
statement or alleged untrue statement of any material fact contained in the Offering Document, or any amendment or supplement thereto, or any related preliminary offering circular or the Exchange Act Reports, 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 in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, including any losses,
claims, damages or liabilities arising out of or based upon any Issuer’s failure to perform its obligations under Section 5(a) of this Agreement, and will reimburse each Purchaser for any legal or other expenses reasonably incurred by such
Purchaser in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Issuers will not be liable in any such case to the extent that any such loss, claim,
damage or liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by
any Purchaser specifically for use therein, it being understood and agreed that the only such information consists of the information described as such in subsection (b) below. 
  
 (b) Each Purchaser will severally and not jointly indemnify and hold harmless each Issuer, its directors and officers and
each person, if any, who controls such Issuer within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities to which such Issuer may become subject, under the Securities Act or the Exchange Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Offering Document, or any
amendment or supplement thereto, or any related preliminary offering circular, or arise out of or are based upon the omission or the alleged omission to state therein 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, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in
reliance upon and in conformity with written information furnished to the Company by such Purchaser specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by the Issuers in connection with investigating or
defending any such loss, claim, damage, liability or action as such expenses are incurred, it being understood and agreed that the only such information furnished by any Purchaser consists of the following information in the Offering Document
furnished on behalf of 

  

 24 

 
each Purchaser: under the caption “Plan of Distribution” the third, ninth and tenth paragraphs; provided, however, that the Purchasers shall not be
liable for any losses, claims, damages or liabilities arising out of or based upon any Issuer’s failure to perform its obligations under Section 5(a) of this Agreement. 
  
 (c) Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such
indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall
not relieve it from any liability that it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that
the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (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 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 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof
other than reasonable costs of investigation. 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 (i) an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such
action and (ii) does not include a statement as to or an admission of fault, culpability or failure to act by or on behalf of any indemnified party. 
  
 (d) If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (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 referred to in subsection (a) or (b) above (i) in such proportion as is
appropriate to reflect the relative benefits received by the Issuers on the one hand and the Purchasers on the other from the offering of the Offered Securities or (ii) if the allocation provided by clause (i) above 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 Issuers on the one hand and the Purchasers on the other in connection with the statements or
omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Issuers on the one hand and the Purchasers on the other shall be deemed to be in
the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Issuers bear to the total discounts and commissions received by the Purchasers from the Issuers under this Agreement. The relative fault
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 Issuers or the Purchasers
and the parties’ 

  

 25 

 
relative intent, knowledge, access to information and opportunity to correct or prevent such untrue 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 the provisions of this subsection (d), no Purchaser shall be required to contribute any amount in excess of the amount by which the total
discounts, fees and commissions received by such Purchaser exceeds the amount of any damages which such Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. The
Purchasers’ obligations in this subsection (d) to contribute are several in proportion to their respective purchase obligations and not joint. 
  
 (e) The obligations of the Issuers under this Section shall be in addition to any liability which the Issuers may otherwise have and shall extend, upon
the same terms and conditions, to each person, if any, who controls any Purchaser within the meaning of the Securities Act or the Exchange Act; and the obligations of the Purchasers under this Section shall be in addition to any liability which the
respective Purchasers may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Issuer within the meaning of the Securities Act or the Exchange Act. 
  
 8. Default of Purchasers. If any Purchaser or Purchasers default in
their obligations to purchase Offered Securities hereunder and the aggregate principal amount Offered Securities that such defaulting Purchaser or Purchasers agreed but failed to purchase does not exceed 10% of the total principal amount of Offered
Securities, the Purchasers may make arrangements satisfactory to the Company for the purchase of such Offered Securities by other persons, including any of the Purchasers, but if no such arrangements are made by the Closing Date, the non-defaulting
Purchasers shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Securities that such defaulting Purchasers agreed but failed to purchase. If any Purchaser or Purchasers so default and the
aggregate principal amount of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total principal amount of Offered Securities and arrangements satisfactory to the Purchasers and the Company for the purchase of
such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Purchaser or the Company, except as provided in Section 9. As used in this
Agreement, the term “Purchaser” includes any person substituted for a Purchaser under this Section. Nothing herein will relieve a defaulting Purchaser from liability for its default. 
  
 9. Survival of Certain Representations and Obligations. The respective
indemnities, agreements, representations, warranties and other statements of the Issuers or their officers and of the several Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any
investigation, or statement as to the results thereof, made by or on behalf of any Purchaser, any Issuer or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the
Offered Securities . If this Agreement is terminated pursuant to Section 8 or if for any reason the purchase of the Offered Securities by the Purchasers is not consummated, the Company shall remain responsible for the expenses to be paid or
reimbursed by it pursuant to Section 5 and the respective obligations of the Issuers and the Purchasers pursuant to Section 7 shall remain in effect. 

  

 26 

 
If the purchase of the Offered Securities by the Purchasers is not consummated for any reason other than solely because of the termination of this Agreement
pursuant to Section 8, the Company will reimburse the Purchasers for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities. 
  
 10. Notices. All communications hereunder will be in writing and, if
sent to the Purchasers will be mailed, delivered or telegraphed and confirmed to the Purchasers, at Credit Suisse First Boston LLC, Eleven Madison Avenue, New York, N.Y. 10010-3629, Attention: Transactions Advisory Group, and Goldman, Sachs &
Co., 85 Broad Street, New York, N.Y. 10004, Attention: Prospectus Department, or, if sent to the Company, will be mailed, delivered or telegraphed and confirmed to it at Clean Harbors, Inc. 1501 Washington St., P.O. Box 859 048, Braintree, MA 02185,
Attention: Mark Burgess; provided, however, that any notice to a Purchaser pursuant to Section 7 will be mailed, delivered or telegraphed and confirmed to such Purchaser. 
  
 11. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their
respective successors and the controlling persons referred to in Section 7, and no other person will have any right or obligation hereunder, except that holders of Offered Securities shall be entitled to enforce the agreements for their benefit
contained in the second and third sentences of Section 5(b) hereof against the Company as if such holders were parties thereto. 
  
 12. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such
counterparts shall together constitute one and the same Agreement. 
  
 13. Applicable 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. 
  
 The Issuers hereby submit to the non-exclusive jurisdiction of the Federal
and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. 
  
 14. Post Closing Matters Relating to Collateral. The Issuers shall obtain and deliver to Collateral Agent, within
sixty business days after the Closing Date, unless waived or extended by Collateral Agent in its sole discretion (x) a survey for the Surveyed Properties located at 660 Lenfest Road, San Jose, Ca; Highway 169 North Industrial Park, Coffeyville, KS;
Hwy 1112 (2029 Bayou Plaquemine Road), Rayne, LA; 32655 Gracie Lane, Plaquemine, LA; Route 322 & I-295 (PO Box 337), Bridgeport, NJ; 1200 Marietta Way, Sparks, NV; 2900 Rockefeller Ave., Cleveland, OH, 1672 E. Highland Road, Twinsburg, OH; 5324
W. 46th Street South, Tulsa, OK; and 4105 Whittaker Ave., Philadelphia, PA and (y) such affidavits or other documents requested by the title company, each in form and substance suitable to the title company to induce it to remove the standard survey
exceptions from the Mortgage Policies and issue survey related endorsements. 
  

 27 

 If the foregoing is in accordance with the Purchasers’ understanding of our agreement, kindly sign
and return to us one of the counterparts hereof, whereupon it will become a binding agreement between the Issuers and the several Purchasers in accordance with its terms.

 REGISTRATION RIGHTS AGREEMENT 
  
 June 30, 2004 
  
 Credit Suisse First Boston LLC 
 Goldman, Sachs & Co. 

	c/o	Credit Suisse First Boston LLC 

 Eleven Madison Avenue

 New York, New York 10010-3629 
  
 Dear Sirs: 
  
 Clean Harbors, Inc., a Massachusetts corporation (the “Issuer”), proposes to issue and sell to Credit Suisse First Boston LLC and Goldman, Sachs & Co. (collectively, the “Initial Purchasers”),
upon the terms set forth in a purchase agreement of even date herewith (the “Purchase Agreement”), $150,000,000 aggregate principal amount of its 111⁄4% Senior Secured Notes due 2012 (the “Initial Securities”) to be
unconditionally guaranteed (the “Guaranties”) by the guarantors listed on Schedule A hereto (the “Guarantors” and together with the Issuer, the “Company”). The Initial Securities will be issued pursuant to an Indenture,
dated as of June 30, 2004 (the “Indenture”) among the Issuer, the Guarantors named therein and U.S. Bank National Association (the “Trustee”). As an inducement to the Initial Purchasers, the Company agrees with the Initial
Purchasers, for the benefit of the holders of the Initial Securities (including, without limitation, the Initial Purchasers), the Exchange Securities (as defined below) and the Private Exchange Securities (as defined below) (collectively the
“Holders”), as follows: 
  
 1. Registered Exchange
Offer. The Company shall, at its own cost, prepare and, not later than 12 months after (or if the last day of the 12th month is not a business day, the first business day thereafter) the date of original issue of the Initial Securities (the
“Issue 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 (the “Exchange Securities”) of the
Company issued under the Indenture and identical in all material respects to the Initial Securities (except for the transfer restrictions relating to the Initial Securities and the provisions relating to the matters described in Section 6 hereof)
that would be registered under the Securities Act. The Company shall use its best efforts to cause such Exchange Offer Registration Statement to become effective under the Securities Act within 15 months (or if the last day of the 15th month is not
a 

  

 
business day, the first business day thereafter) after the Issue Date of the Initial Securities and shall keep the Exchange Offer Registration Statement
effective for not less than 20 business 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 effects the Registered Exchange Offer, the
Company will be entitled to close the Registered Exchange Offer 20 business days after the commencement thereof; provided that the Company has accepted all the Initial Securities theretofore validly tendered in accordance with the terms of
the Registered Exchange Offer. 
  
 Following the declaration of
the effectiveness of the Exchange Offer Registration Statement, the Company shall promptly commence the Registered Exchange Offer, it being the objective of such Registered Exchange Offer to enable each Holder of Transfer Restricted Securities (as
defined in Section 6 hereof) 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 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 Exchange Securities acquired in exchange for 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) and (ii) the Company shall make such prospectus and any amendment or supplement thereto, available to 

  

 -2- 

 
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. 
  
 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 (including the existence of restrictions on transfer under the Securities Act and the securities laws of the several states of the United States, but excluding provisions
relating to the matters described in Section 6 hereof) 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; 
  
 (b) keep the Registered Exchange Offer open for not less than 20 business 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 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 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, Exchange Securities or Private Exchange Securities, as the case may 

  

 -3- 

 
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 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. 
  
 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 within 16 months of the Issue Date, (iii) within 30 days following consummation of the Registered Exchange Offer, any 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 consummation of 

  

 -4- 

 
the Registered Exchange Offer or (iv) any Holder (other than an Exchanging Dealer) is not eligible to participate in the Registered Exchange Offer or, in the
case of any Holder (other than an Exchanging Dealer) that participates in the Registered Exchange Offer, such Holder does not receive freely tradeable Exchange Securities on the date of the exchange, the Company shall take the following actions:

  
 (a) The Company shall, at its cost, as
promptly as practicable (but in no event more than 30 days after so required or requested pursuant to this Section 2) file with the Commission and thereafter shall use its best efforts to cause to be declared effective a registration statement (the
“Shelf Registration Statement” and, together with the Exchange Offer Registration Statement, a “Registration Statement”) on an appropriate form under the Securities Act relating to the offer and sale of the Transfer Restricted
Securities (as defined in Section 6 hereof) 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 no longer restricted securities (as defined in Rule 144 under the Securities Act, or any successor rule thereof). 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 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 

  

 -5- 

 
thereof and each supplement, if any, to the prospectus included therein and, in the event that an Initial Purchaser (with respect to any portion of an unsold
allotment from the original offering) 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 Exchange
Offer 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 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
Purchasers, 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 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; 
  

 -6- 

 (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). 
  
 (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 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 

  

 -7- 

 
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. 
  
 (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 

  

 -8- 

 
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 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; provided, however, 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 

  

 -9- 

 
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 (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 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.

  
 (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(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 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) 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 

  

 -10- 

	 	 
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 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. The Company shall bear all fees and expenses
incurred in connection with the performance of its obligations under Sections 1 through 3 hereof (including the reasonable fees and expenses, if any, of Cahill Gordon & Reindel LLP, counsel for the Initial Purchasers, incurred in connection with
the Registered Exchange Offer), whether or not the Registered Exchange Offer or a Shelf Registration is filed or becomes effective, and, in the event of a Shelf Registration, shall bear or reimburse the Holders of the Securities covered thereby for
the reasonable fees and disbursements of one firm of counsel designated by the Holders of a majority in principal amount of the Initial Securities covered thereby to act as counsel for the Holders of the Initial Securities in connection therewith.

  
 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 

  

 -11- 

 
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. 
  

(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 

  

 -12- 

 
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 failure to notify the indemnifying party shall not relieve the indemnifying party from any liability that it may have under subsection (a) or (b) above except to the
extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability
that it may have to an indemnified party otherwise than under subsection (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 (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action, and (ii) 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 

  

 -13- 

 
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 Initial Securities shall be assessed as follows if any of the following
events occur (each such event in clauses (i) through (iv) below a “Registration Default”: 
  
 (i) If by June 30, 2005, neither the Exchange Offer Registration Statement nor, if required in lieu thereof, a Shelf Registration
Statement has been filed with the Commission; 
  
 (ii) If by September 30, 2005, neither the Exchange Offer Registration Statement nor, if required in lieu thereof, the Shelf Registration Statement is declared effective by the Commission; 
  
 (iii) If by October 30, 2005, the Registered Exchange offer
is not consummated; or 
  
 (iv) If after either
the Exchange Offer Registration Statement or the Shelf Registration Statement is declared effective (A) such Registration Statement thereafter ceases to be effective; or (B) such Registration Statement or the related prospectus ceases to be usable
(except as permitted in paragraph (b)) in connection with resales of Transfer 

  

 -14- 

 
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. 
  
 Additional Interest shall accrue on the Initial 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, at a rate of 0.25% per annum for the first 90-day period following the
occurrence of a Registration Default. Such 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 1.00% per
annum. 
  
 (b) A Registration Default referred to in Section
6(a)(iv)(B) 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 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 clause (i), (ii), (iii) or (iv) of Section 6(a) above will be payable
in cash on the regular interest payment dates with respect to the Initial Securities. The amount of Additional Interest will be determined by multiplying the applicable Additional Interest rate by the principal amount of the Initial Securities,
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 Transfer Restricted 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 a Initial Security for an Exchange Note, the date on which such Exchange Note 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 Initial Security has been effectively registered under the Securities Act and disposed of in accordance with the Shelf 

  

 -15- 

 
Registration Statement or (iv) the date on which such Initial Securities 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 Initial 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 Initial Securities may reasonably request, all to the extent required from time to time to enable such Holder to sell Initial 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 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) 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. 
  
 (b) Notices. All notices and other communications provided for or

the Holders of such required percentage. 
  
 If the foregoing is
in accordance with your understanding of our agreement, please sign and return to the Issuer a counterpart hereof, whereupon this instrument, along with all counterparts, will become a binding agreement among the several Initial Purchasers, 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 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                     ,
20     , 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.

 If the undersigned is not a
broker-dealer, the undersigned represents that it is not engaged in, and does not intend to engage in, a distribution of Exchange Securities. If the undersigned is a broker-dealer that 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, it acknowledges that it will deliver a prospectus in connection with any resale of such Exchange Securities; however, by so acknowledging
and by delivering a prospectus, the undersigned will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.
