SECTION 2. HOLDERS

     A Person is deemed to be a holder of Entitled Securities (each, a “Holder”) whenever such Person owns Entitled Securities.

SECTION 3. REGISTERED EXCHANGE OFFER

     (a) The Company and the Guarantors shall (i) unless the Exchange Offer shall not be permitted by applicable law or Commission policy (after the procedures set forth in Section 6(a)(i) below have been complied with), cause the Exchange Offer Registration Statement to be filed with the Commission on or prior to the 180th day after the date hereof (such 180th day being the “Exchange Filing Deadline”), (ii) use their commercially reasonable efforts to cause such Exchange Offer Registration Statement to become effective on or prior to the 300th day after the date hereof (such 300th day being the “Exchange Effectiveness Deadline”), (iii) in connection with the foregoing, (A) file all pre-effective amendments to such Exchange Offer Registration Statement as may be necessary in order to cause it to become effective, (B) file, if applicable, a post-effective amendment to such Exchange Offer Registration Statement, and (C) cause all necessary filings, if any, in connection with the registration and qualification of the Exchange Notes to be made under the Blue Sky laws of such jurisdictions as are necessary to

permit Consummation of the Exchange Offer, and (iv) on or prior to the date that is 30 days after the date on which the Exchange Offer Registration Statement became effective, commence and Consummate the Exchange Offer and use their commercially reasonable efforts to issue the Exchange Notes in exchange for all Initial Notes tendered prior thereto in the Exchange Offer. The Exchange Offer shall be on the appropriate form permitting (i) registration of the Exchange Notes to be offered in exchange for the Initial Notes that are Entitled Securities and (ii) resales of Exchange Notes by Broker-Dealers that tendered into the Exchange Offer Initial Notes that such Broker-Dealer acquired for its own account as a result of market-making activities or other trading activities (other than Initial Notes acquired directly from the Company or any of its Affiliates) as contemplated by Section 3(c) below.

     (b) The Company and the Guarantors shall use all commercially reasonable efforts to cause the Exchange Offer Registration Statement to be effective continuously, and shall keep the Exchange Offer open for a period of not less than the minimum period required under applicable federal and state securities laws to Consummate the Exchange Offer; provided, however, that in no event shall such period be less than 20 Business Days. The Company and the Guarantors shall cause the Exchange Offer to comply with all applicable federal and state securities laws. No securities other than the Exchange Notes shall be included in the Exchange Offer Registration Statement. The Company and the Guarantors shall use all commercially reasonable efforts to cause the Exchange Offer to be Consummated on the earliest practicable date after the Exchange Offer Registration Statement has become effective, but in no event later than 30 Business Days or longer, if required by the federal securities laws, after the date on which the Exchange Offer Registration Statement has become effective (such 30th day, or such later date required by the federal securities laws, being the “Consummation Deadline”).

     (c) The Company shall include a “Plan of Distribution” section, in the form attached hereto as Annex A, in the Prospectus contained in the Exchange Offer Registration Statement and indicate therein that any Broker-Dealer who holds Entitled Securities that were acquired for the account of such Broker-Dealer as a result of market-making activities or other trading activities (other than Initial Notes acquired directly from the Company or any Affiliate of the Company) may exchange such Entitled Securities pursuant to the Exchange Offer. Such “Plan of Distribution” section shall also contain all other information with respect to such sales by such Broker-Dealers that the Commission may require in order to permit such sales pursuant thereto, but such “Plan of Distribution” shall not name any such Broker-Dealer or disclose the amount of Entitled Securities held by any such Broker-Dealer, except to the extent required by the Commission as a result of a change in policy, rules or regulations after the date of this Agreement.

     Because such Broker-Dealer may be deemed to be an “underwriter” within the meaning of the Act and must, therefore, deliver a prospectus meeting the requirements of the Act in connection with its initial sale of any Exchange Notes received by such Broker-Dealer in the Exchange Offer, the Company and Guarantors shall permit the use of the Prospectus contained in the Exchange Offer Registration Statement by such Broker-Dealer to satisfy such prospectus delivery requirement. To the extent necessary to ensure that the Prospectus contained in the Exchange Offer Registration Statement is available for sales of Exchange Notes by Broker-Dealers, the Company and the Guarantors agree to use all commercially reasonable efforts to keep the Exchange Offer Registration Statement continuously effective, supplemented, amended

and current as required by and subject to the provisions of Sections 6(a) and (c) hereof and in conformity with the requirements of this Agreement, the Act and the policies, rules and regulations of the Commission as announced from time to time, for a period of 180 days from the Consummation Deadline (as extended pursuant to Section 6(d)) or such shorter period as will terminate when all Entitled Securities covered by such Registration Statement have been sold pursuant thereto. The Company and the Guarantors shall provide sufficient copies of the latest version of such Prospectus to such Broker-Dealers, promptly upon request, and in no event later than two Business Days after such request, at any time during such period.

SECTION 4. SHELF REGISTRATION

     (a) Shelf Registration. If (i) the Company and the Guarantors are not (A) required to file the Exchange Offer Registration Statement or (B) permitted to Consummate the Exchange Offer because the Exchange Offer is not permitted by applicable law or Commission policy (after the Company and the Guarantors have complied with the procedures set forth in Section 6(a)(i) below) or (ii) any Holder notifies the Company and the Guarantors within 20 Business Days following Consummation of the Exchange Offer that (A) such Holder is prohibited by law or Commission policy from participating in the Exchange Offer, (B) such Holder may not resell the Exchange Notes acquired by it in the Exchange Offer 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 by such Holder or (C) such Holder is a Broker-Dealer and holds Initial Notes acquired directly from the Company or any of its Affiliates, then the Company and the Guarantors, shall:

     (x) use their commercially reasonable efforts on or prior to 90 days after the earlier of (i) the date as of which the Company determines that the Exchange Offer Registration Statement will not be or cannot be, as the case may be, filed as a result of clause (a)(i) above and (ii) the date on which the Company receives the notice specified in clause (a)(ii) above (90 days after such earlier date, the “Shelf Filing Deadline”), to file a shelf registration statement with the Commission pursuant to Rule 415 under the Act (which may be an amendment to the Exchange Offer Registration Statement (the “Shelf Registration Statement”)), covering the resale of all Entitled Securities, and

     (y) use their commercially reasonable efforts to cause such Shelf Registration Statement to become effective on or prior to 90 days after the Shelf Filing Deadline (such 90th day the “Shelf Effectiveness Deadline”).

     If, after the Company and the Guarantors have filed an Exchange Offer Registration Statement that satisfies the requirements of Section 3(a) above, the Company and the Guarantors are required to file and make effective a Shelf Registration Statement solely because the Exchange Offer is not permitted under applicable federal law (i.e., clause (a)(i)(B) above), then the filing of the Exchange Offer Registration Statement shall be deemed to satisfy the requirements of clause (x) above; provided that, in such event, the Company and the Guarantors shall remain obligated to meet the Shelf Effectiveness Deadline set forth in clause (y).

     To the extent necessary to ensure that the Shelf Registration Statement is available for sales of Entitled Securities by the Holders thereof entitled to the benefit of this Section 4(a), the

Company and the Guarantors shall use all commercially reasonable efforts to keep any Shelf Registration Statement required by this Section 4(a) continuously effective, supplemented, amended and current as required by and subject to the provisions of Sections 6(b) and 6(c) hereof and in conformity with the requirements of this Agreement, the Act and the policies, rules and regulations of the Commission as announced from time to time, for a period of at least two years (as extended pursuant to Section 6(c)(i) or 6(d)) following the Closing Date, or such shorter period as will terminate when all Entitled Securities covered by such Shelf Registration Statement have been sold pursuant thereto or are no longer Entitled Securities.

     (b) Provision by Holders of Certain Information in Connection with the Shelf Registration Statement. No Holder may include any of its Entitled Securities in any Shelf Registration Statement pursuant to this Agreement unless and until such Holder furnishes to the Company in writing, within 15 days after receipt of a request therefor, the information specified in Item 507 or 508 of Regulation S-K, as applicable, of the Act, or other information reasonably requested by the Company and required by Regulation S-K of the Act, for use in connection with any Shelf Registration Statement or Prospectus or preliminary Prospectus included therein. No Holder shall be entitled to Special Interest pursuant to Section 5 hereof unless and until (and from and after such time) such Holder shall have provided all such information. Each selling Holder agrees to promptly furnish additional information required to be disclosed in order to make the information previously furnished to the Company by such Holder not materially misleading and shall promptly supply such other information as the Company may from time to time reasonably request.

SECTION 5. ADDITIONAL INTEREST

     If (i) any Registration Statement required by this Agreement is not filed with the Commission on or prior to the applicable Filing Deadline, (ii) any such Registration Statement has not been declared effective by the Commission on or prior to the applicable Effectiveness Deadline, (iii) the Exchange Offer has not been Consummated on or prior to the Consummation Deadline, or (iv) any Registration Statement required by this Agreement is filed and declared effective but shall thereafter cease to be effective or fail to be usable for its intended purpose during the applicable periods specified herein without being succeeded in 30 days by a post-effective amendment to the Registration Statement or an additional Registration Statement that causes the Exchange Offer Registration Statement (and/or, if applicable, the Shelf Registration Statement) to again be declared effective or made usable (each such event referred to in clauses (i) through (iv), a “Registration Default”), then the Company agrees to pay to each Holder affected thereby additional interest (“Special Interest”) at a rate of .25% per annum for the first 90-day period immediately following the occurrence of such Registration Default. The rate of Special Interest shall increase by an additional .25% per annum with respect to each subsequent 90-day period until all Registration Defaults have been cured, up to a maximum rate of Special Interest for all Registration Defaults of 1.0% per annum; provided that the Company shall in no event be required to pay Special Interest for more than one Registration Default at any given time. Notwithstanding anything to the contrary set forth herein, (1) upon filing of the Exchange Offer Registration Statement (and/or, if applicable, the Shelf Registration Statement), in the case of clause (i) above, (2) upon the effectiveness of the Exchange Offer Registration Statement (and/or, if applicable, the Shelf Registration Statement), in the case of clause (ii) above, (3) upon Consummation of the Exchange Offer, in the case of clause (iii) above, or (4) upon the filing of a

post-effective amendment to the Registration Statement or an additional Registration Statement that causes the Exchange Offer Registration Statement (and/or, if applicable, the Shelf Registration Statement) to again be declared effective or made usable in the case of clause (iv) above, the Special Interest payable with respect to the Entitled Securities as a result of such clause (i), (ii), (iii), or (iv), as applicable, shall cease.

     All accrued Special Interest shall be paid by the Company (or the Company will cause the Paying Agent to make such payment on its behalf) to the Holders entitled thereto, in the manner provided for the payment of interest in the Indenture, on each Interest Payment Date, as more fully set forth in the Indenture, the Initial Notes and the Exchange Notes. Notwithstanding the fact that any securities for which Special Interest are due cease to be Entitled Securities, all obligations of the Company to pay Special Interest with respect to securities that accrued prior to the time that such securities ceased to be Entitled Securities shall survive until such time as such obligations with respect to such securities shall have been satisfied in full.

SECTION 6. REGISTRATION PROCEDURES

     (a) Exchange Offer Registration Statement. In connection with the Exchange Offer, the Company and the Guarantors shall (x) comply with all applicable provisions of Section 6(c) below, (y) use all commercially reasonable efforts to effect such exchange and to permit the resale of Exchange Notes by Broker-Dealers that tendered in the Exchange Offer Initial Notes that such Broker-Dealer acquired for its own account as a result of its market-making activities or other trading activities (other than Initial Notes acquired directly from the Company or any of its Affiliates) being sold in accordance with the intended method or methods of distribution thereof, and (z) comply with all of the following provisions:

     (i) If, following the date hereof there has been announced a change in Commission policy with respect to exchange offers such as the Exchange Offer, that in the reasonable opinion of counsel to the Company raises a substantial question as to whether the Exchange Offer is permitted by applicable federal law, the Company and the Guarantors hereby agree either to (x) seek a no-action letter or other favorable decision from the Commission allowing the Company and the Guarantors to Consummate an Exchange Offer for such Entitled Securities, or (y) file, in accordance with Section 4(a) hereof, a Shelf Registration Statement to permit the registration and/or resale of the Entitled Securities that would otherwise be covered by the Exchange Offer Registration Statement but for the announcement of a chance in Commission policy. In the case of clause (x) above, the Company and the Guarantors hereby agree to pursue the issuance of such a decision to the Commission staff level but shall not be required to take action not commercially reasonable to affect a change of Commission policy. In connection with the foregoing, the Company and the Guarantors hereby agree to 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 (A) participating in telephonic conferences with the Commission, (B) 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 such an Exchange Offer should be permitted, and (C) diligently pursuing a resolution (which need not be favorable and which need not be a written resolution) by the Commission staff.

     (ii) As a condition to its participation in the Exchange Offer, each Holder (including, without limitation, any Holder who is a Broker-Dealer) shall furnish, upon the request of the Company, prior to the Consummation of the Exchange Offer, a written representation to the Company and the Guarantors (which may be contained in the letter of transmittal contemplated by the Exchange Offer Registration Statement) to the effect that (A) it is not an Affiliate of the Company, (B) it is not engaged in, and does not intend to engage in, and has no arrangement or understanding with any person to participate in, a distribution of the Exchange Notes to be issued in the Exchange Offer, (C) it is acquiring the Exchange Notes in its ordinary course of business, (D) such Holder has full power and authority to transfer the Initial Notes in exchange for the Exchange Notes and that the Company will acquire good and unencumbered title thereto free and clear of any liens, restrictions, charges or encumbrances and not subject to any adverse claims and (E) only if such Holder is a Broker-Dealer that will receive Exchange Notes in exchange for Initial Notes that such Broker-Dealer acquired for its own private account as a result of market making or other trading activities, it will deliver a Prospectus, as required by law, in connection with any sale of such Exchange Notes and comply with any other applicable provisions of the Act. As a condition to its participation in the Exchange Offer each Holder using the Exchange Offer to participate in a distribution of the Exchange Notes shall acknowledge and agree that, if the resales are of Exchange Notes obtained by such Holder in exchange for Initial Notes acquired directly from the Company or an Affiliate thereof, it (1) could not, under Commission policy as in effect on the date of this Agreement, rely on the position of the Commission enunciated in ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ and Co., Inc. (available June 5, 1991) and Exxon Capital Holdings Corporation (available May 13, 1988), as interpreted in the Commission’s letter to Shearman & Sterling dated July 2, 1993, and similar no-action letters (including, if applicable, any no-action letter obtained pursuant to clause (i) above), and (2) must comply with the registration and prospectus delivery requirements of the Act in connection with a secondary resale transaction and that such a secondary resale transaction must be covered by an effective registration statement containing the selling security holder information required by Item 507 or 508, as applicable, of Regulation S-K.

     (b) Shelf Registration Statement. In connection with the Shelf Registration Statement, the Company and the Guarantors shall:

     (i) comply with all the provisions of Section 6(c) below and use all commercially reasonable efforts to effect such registration to permit the sale of the Entitled Securities being sold in accordance with the intended method or methods of distribution thereof (as indicated in the information furnished to the Company pursuant to Section 4(b) hereof), and pursuant thereto the Company and the Guarantors will prepare and file with the Commission a Registration Statement relating to the registration on any appropriate form under the Act, which form shall be available for the sale of the Entitled Securities in accordance with the intended method or methods of distribution thereof within the time periods and otherwise in accordance with the provisions hereof, and

     (ii) issue to any Holder or purchaser of Initial Notes covered by any Shelf Registration Statement contemplated by this Agreement, upon the request of any such Holder or purchaser, registered Initial Notes having an aggregate principal amount equal

to the aggregate principal amount of Initial Notes in the names as such Holder or purchaser shall designate.

     (c) General Provisions. In connection with any Registration Statement and any related Prospectus required by this Agreement, the Company and the Guarantors shall:

     (i) use all commercially reasonable efforts to keep such Registration Statement continuously effective and provide all requisite financial statements for the period specified in Section 3 or 4 of this Agreement, as applicable;

     (ii) upon the occurrence of any event that would cause any such Registration Statement or the Prospectus contained therein (A) to contain an untrue statement of material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, or (B) not to be effective and usable for resale of Entitled Securities during the period required by this Agreement, the Company and the Guarantors shall file promptly an appropriate amendment to such Registration Statement curing such defect, and, if Commission review is required, use all commercially reasonable efforts to cause such amendment to be declared effective as soon as practicable;

     (iii) prepare and file with the Commission such amendments and post-effective amendments to the applicable Registration Statement as may be necessary to keep such Registration Statement effective for the applicable period set forth in Section 3 or 4 hereof, as the case may be; cause the Prospectus to be supplemented by any required prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the Act, and to comply fully with Rules 424, 430A, and 462, as applicable, under the Act in a timely manner; and comply with the provisions of the Act with respect to the disposition of all securities covered by such Registration Statement during the applicable period in accordance with the intended method or methods of distribution by the sellers thereof set forth in such Registration Statement or supplement to the Prospectus;

     (iv) advise (a) each Holder whose Entitled Securities have been included in a Shelf Registration Statement (in the case of a Shelf Registration Statement), and (b) each Holder who has provided notice to the Company promptly and, if requested by such Holder, confirm such advice in writing, (A) when the Prospectus or any prospectus supplement or post-effective amendment has been filed, and, with respect to any applicable Registration Statement or any post-effective amendment thereto, when the same has become effective, (B) of any request by the Commission for amendments to the Registration Statement or amendments or supplements to the Prospectus or for additional information relating thereto, (C) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement under the Act or of the suspension by any state securities commission of the qualification of the Entitled Securities for offering or sale in any jurisdiction, or the initiation of any proceeding for any of the preceding purposes, and (D) 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, any amendment or supplement thereto or any document incorporated by reference therein do not contain an untrue statement of

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. If at any time the Commission shall issue any stop order suspending the effectiveness of the Registration Statement, or any state securities commission or other regulatory authority shall issue an order suspending the qualification or exemption from qualification of the Entitled Securities under state securities or Blue Sky laws, the Company and the Guarantors shall use all commercially reasonable efforts to obtain the withdrawal or lifting of such order at the earliest possible time;

     (v) subject to Section 6(d), if any fact or event contemplated by Section 6(c)(iii)(D) above shall exist or have occurred, prepare a supplement or post-effective amendment to the Registration Statement or related Prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchasers of Entitled Securities, the Prospectus will not contain an 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;

     (vi) furnish to each Holder whose Entitled Securities have been included in a Shelf Registration Statement (in the case of a Shelf Registration Statement) in connection with such exchange, registration or sale, if any, before filing with the Commission, copies of any Registration Statement or any Prospectus included therein or any amendments or supplements to any such Registration Statement or Prospectus (including all documents incorporated by reference after the initial filing of such Registration Statement), which documents will be subject to the reasonable review and comment of such Holders in connection with such sale, if any, for a period of at least three Business Days, and the Company will not file any such Registration Statement or Prospectus or any amendment or supplement to any such Registration Statement or Prospectus (including all such documents incorporated by reference) to which such Holders shall reasonably object within three Business Days after the receipt thereof. A Holder shall be deemed to have reasonably objected to such filing if such Registration Statement, amendment, Prospectus or supplement, as applicable, as proposed to be filed, contains an untrue statement of a material fact or omits to state any material fact necessary to make the statements therein not misleading or fails to comply with the applicable requirements of the Act;

     (vii) make available, at reasonable times, for inspection by each Holder whose Entitled Securities have been included in a Shelf Registration Statement (in the case of a Shelf Registration Statement) and any attorney or accountant retained by such Holders, all financial and other records, pertinent corporate documents of the Company and the Guarantors reasonably requested and cause the Company’s and the Guarantors’ officers, directors and employees to supply all information reasonably requested by any such Holder, attorney or accountant in connection with such Registration Statement or any post-effective amendment thereto subsequent to the filing thereof and prior to its effectiveness; provided that any Holder or representative thereof requesting or receiving such information shall agree to be bound by reasonable confidentiality agreements and procedures with respect thereto;

     (ix) furnish to each Holder whose Entitled Securities have been included in a Shelf Registration Statement (in the case of a Shelf Registration Statement) in connection with such exchange, registration or sale, without charge, at least one copy of the Registration Statement, as first filed with the Commission, and of each amendment thereto, including all documents incorporated by reference therein and all exhibits (including exhibits incorporated therein by reference);

     (x) deliver to each Holder whose Entitled Securities have been included in a Shelf Registration Statement (in the case of a Shelf Registration Statement) without charge, as many copies of the Prospectus (including each preliminary prospectus) and any amendment or supplement thereto as such Holders reasonably may request; the Company and the Guarantors hereby consent to the use (in accordance with law and subject to Section 6(d) hereof) of the Prospectus and any amendment or supplement thereto by each selling Holder in connection with the offering and the sale of the Entitled Securities covered by the Prospectus or any amendment or supplement thereto;

     (xi) enter into such agreements (including an underwriting agreement), and make such representations and warranties, and take all such other actions in connection therewith in order to expedite or facilitate the disposition of the Entitled Securities pursuant to any Registration Statement contemplated by this Agreement, all to such extent as may be customarily and reasonably requested by the Purchasers or, in the case of registration for resale of Entitled Securities pursuant to the Shelf Registration Statement, by any Holder or Holders of Entitled Securities who hold at least 50% in aggregate principal amount of such class of Entitled Securities; provided, that, the Company and the Guarantors shall not be required to enter into any such agreement more than once with respect to all of the Entitled Securities and, in the case of a Shelf Registration Statement, may delay entering into such agreement if the Board of Directors of the Company determines in good faith that it is in the best interests of the Company and the Guarantors not to disclose the existence of or facts surrounding any proposed or pending material corporate transaction involving the Company and the Guarantors. In such connection, the Company and the Guarantors shall:

     (A) upon the request of any Holder, furnish (or in the case of paragraphs (2) and (3), use its commercially reasonable efforts to cause to be furnished) to each such Holder (in the case of the Shelf Registration Statement)

and any underwriter, upon Consummation of the Exchange Offer or the effectiveness of the Shelf Registration Statement, as the case may be:

     (1) a certificate, dated such date, signed on behalf of the Company and each Guarantor by (x) the Chief Executive Officer or any Vice President, and (y) a principal financial or accounting officer of the Company and such Guarantor, confirming, as of the date thereof, such matters as such Holders may reasonably request;

     (2) an opinion, dated the date of Consummation of the Exchange Offer or the date of effectiveness of the Shelf Registration Statement, as the case may be, of counsel for the Company and the Guarantors in customary form and covering such other matters as such Holder may reasonably request, and in any event including a statement to the effect that such counsel has participated in conferences with officers and other representatives of the Company and the Guarantors and representatives of the independent public accountants for the Company and the Guarantors and representatives of the underwriters, if any, and their counsel at which the contents of the Registration Statement and related matters were discussed and, although such counsel need not pass upon or assume responsibility for the accuracy, completeness or fairness of such statements (relying as to materiality to the extent such counsel deems appropriate upon the statements of officers and other representatives of the Company and the Guarantors and without independent check or verification), no facts came to such counsel’s attention that caused such counsel to believe that the applicable Registration Statement, at the time such Registration Statement or any post-effective amendment thereto became effective and, in the case of the Exchange Offer Registration Statement, as of the date of Consummation of the Exchange Offer, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or that the Prospectus contained in such Registration Statement as of its date and, in the case of the opinion dated the date of Consummation of the Exchange Offer, as of the date of Consummation, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. Such counsel may state further that such counsel assumes no responsibility for, and has not independently verified, the accuracy, completeness or fairness of the financial statements, schedules or other financial data or the reserve data included in any Registration Statement contemplated by this Agreement or the related Prospectus and need express no view as to the accounting or financial records from which such financial statements, schedules and data are derived; and

     (3) a customary comfort letter, dated the date of Consummation of the Exchange Offer, or as of the date of effectiveness of

the Shelf Registration Statement, as the case may be, from the Company’s independent accountants, in the customary form and covering matters of the type customarily covered in comfort letters to underwriters in connection with underwritten offerings, and affirming the matters set forth in the comfort letters delivered pursuant to Section 7(a) of the Purchase Agreement; and

     (B) deliver such other documents and certificates as may be reasonably requested by the selling Holders to evidence compliance with the matters covered in clause (A) above and with any customary conditions contained in any agreement entered into by the Company and the Guarantors pursuant to this clause (xi);

     (xii) prior to any public offering of Entitled Securities, cooperate with the selling Holders and their counsel in connection with the registration and qualification of the Entitled Securities under the securities or Blue Sky laws of such jurisdictions as the selling Holders may request and do any and all other acts or things necessary or advisable to enable the disposition in such jurisdictions of the Entitled Securities covered by the applicable Registration Statement; provided, however, that the Company and the Guarantors shall not be required to register or qualify as a foreign entity where it is not now so qualified or to take any action that would subject it to the service of process in suits or to taxation, other than as to matters and transactions relating to the Registration Statement, in any jurisdiction where it is not now so subject;

     (xiii) in connection with any sale of Entitled Securities that will result in such securities no longer being Entitled Securities, cooperate with the Holders to facilitate the timely preparation and delivery of certificates representing Entitled Securities to be sold and not bearing any restrictive legends; and to register such Entitled Securities in such denominations and such names as the selling Holders may request at least two Business Days prior to such sale of Entitled Securities;

     (xiv) use all commercially reasonable efforts to cause the disposition of the Entitled Securities covered by the Registration Statement to be registered with or approved by such other governmental agencies or authorities as may be necessary to enable the seller or sellers thereof to consummate the disposition of such Entitled Securities, subject to the proviso contained in clause (xii) above;

     (xv) provide a CUSIP number for all Entitled Securities not later than the effective date of a Registration Statement covering such Entitled Securities and provide the Trustee under the Indenture with printed certificates for the Entitled Securities which are in a form eligible for deposit with the Depository Trust Company;

     (xvi) otherwise use all commercially reasonable efforts to comply with all applicable rules and regulations of the Commission, and make generally available to its security holders with regard to any applicable Registration Statement, as soon as practicable, a consolidated earnings statement meeting the requirements of Rule 158 under the Act (which need not be audited) covering a twelve-month period beginning

after the effective date of the Registration Statement (as such term is defined in paragraph (c) of Rule 158 under the Act); and

     (xvii) cause the Indenture to be qualified under the TIA not later than the effective date of the first Registration Statement required by this Agreement and, in connection therewith, cooperate with the Trustee and the Holders to effect such changes to the Indenture as may be required for such Indenture to be so qualified in accordance with the terms of the TIA; and execute all documents that may be required to effect such changes and all other forms and documents required to be filed with the Commission to enable such Indenture to be so qualified in a timely manner.

     (d) Restrictions on Holders. Each Holder agrees by acquisition of an Entitled Security that, upon receipt of the notice referred to in Section 6(c)(ii), 6(c)(iv)(B) or 6(c)(iv)(C) or any notice from the Company of the existence of any fact of the kind described in Section 6(c)(iv)(D) hereof (in each case, a “Suspension Notice”), such Holder will forthwith discontinue disposition of Entitled Securities pursuant to the applicable Registration Statement until (i) such Holder has received copies of the supplemented or amended Prospectus contemplated by Section 6(c)(iv) hereof, or (ii) such Holder is advised in writing by the Company that the use of the Prospectus may be resumed, and has received copies of any additional or supplemental filings that are incorporated by reference in the Prospectus (in each case, the “Recommencement Date”). Each Holder receiving a Suspension Notice hereby agrees that it will either (i) destroy any Prospectuses, other than permanent file copies, then in such Holder’s possession which have been replaced by the Company with more recently dated Prospectuses, or (ii) deliver to the Company (at the Company’s expense) all copies, other than permanent file copies, then in such Holder’s possession of the Prospectus covering such Entitled Securities that was current at the time of receipt of the Suspension Notice. The time period regarding the effectiveness of such Registration Statement set forth in Section 3 or 4 hereof, as applicable, shall be extended by a number of days equal to the number of days in the period from and including the date of delivery of the Suspension Notice to the Recommencement Date.

SECTION 7. REGISTRATION EXPENSES

     All expenses incident to the Company’s and the Guarantors’ performance of or compliance with this Agreement will be borne by the Company, regardless of whether a Registration Statement becomes effective, including without limitation: (i) all registration and filing fees and expenses; (ii) all fees and expenses of compliance with federal securities and state Blue Sky or securities laws; (iii) all expenses of printing (including printing certificates for the Exchange Notes to be issued in the Exchange Offer and printing of Prospectuses), messenger and delivery services and telephone; (iv) all fees and disbursements of counsel for the Company and the Guarantors and one counsel for all of the Holders of Entitled Securities selected by the Holders of a majority in principal amount of Entitled Securities being registered; (v) all application and filing fees in connection with listing the Exchange Notes 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 and the Guarantors (including the expenses of any special audit and comfort letters required by or incident to such performance); provided, however, that in no event shall the Company or the

Guarantors be responsible for any underwriting discounts, commissions or fees attributable to the sale or other disposition of Entitled Securities.

     The Company will, in any event, bear its and the Guarantors’ 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 or the Guarantors.

SECTION 8. INDEMNIFICATION

     (a) The Company and the Guarantors agree, jointly and severally, to indemnify and hold harmless each Holder, its directors, officers and each Person, if any, who controls such Holder (within the meaning of Section 15 of the Act or Section 20 of the Exchange Act), from and against any and all losses, claims, damages, liabilities or judgments, (including without limitation, any legal or other expenses incurred in connection with investigating or defending any matter, including any action that could give rise to any such losses, claims, damages, liabilities or judgments) caused by any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement, preliminary prospectus or Prospectus, Free Writing Prospectus or any “issuer information” (as defined in Rule 433 of the Act) filed or required to be filed pursuant to Rule 433(d) under the Act (or any amendment or supplement thereto), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, except insofar as such losses, claims, damages, liabilities or judgments are caused by an untrue statement or omission or alleged untrue statement or omission that is based upon information relating to any of the Holders furnished in writing to the Company by or on behalf of any of the Holders.

     (b) Each Holder agrees, severally and not jointly, to indemnify and hold harmless the Company and the Guarantors, and their respective directors and officers, and each Person, if any, who controls (within the meaning of Section 15 of the Act or Section 20 of the Exchange Act) the Company, or the Guarantors to the same extent as the foregoing indemnity from the Company and the Guarantors set forth in section (a) above, but only with reference to information relating to such Holder furnished in writing to the Company by or on behalf of such Holder expressly for use in any Registration Statement. In no event shall any Holder, its directors, officers or any Person who controls such Holder be liable or responsible for any amount in excess of the amount by which the total amount received by such Holder with respect to its sale of Entitled Securities pursuant to a Registration Statement exceeds the sum of: (i) the amount paid by such Holder for such Entitled Securities plus (ii) the amount of any damages that such Holder, its directors, officers or any Person who controls such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.

     (c) In case any action shall be commenced involving any person in respect of which indemnity may be sought pursuant to Section 8(a) or 8(b) (the “indemnified party”), the indemnified party shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party shall assume the defense of such action, including the employment of counsel reasonably satisfactory to the indemnified

party and the payment of all fees and expenses of such counsel, as incurred (except that in the case of any action in respect of which indemnity may be sought pursuant to both Sections 8(a) and 8(b), a Holder shall not be required to assume the defense of such action pursuant to this Section 8(c), but may employ separate counsel and participate in the defense thereof, but the fees and expenses of such counsel, except as provided below, shall be at the expense of the Holder). Any indemnified party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the indemnified party unless (i) the employment of such counsel has been specifically authorized in writing by the indemnifying party, (ii) the indemnifying party has failed to assume the defense of such action or employ counsel reasonably satisfactory to the indemnified party, or (iii) the named parties to any such action (including any impleaded parties) include both the indemnified party and the indemnifying party, and the indemnified party has been advised by such counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party (in which case the indemnifying party shall not have the right to assume the defense of such action on behalf of the indemnified party). In any such case, the indemnifying party 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 fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all indemnified parties and all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by a majority of the Holders, in the case of the parties indemnified pursuant to Section 8(a), and by the Company and Guarantors, in the case of parties indemnified pursuant to Section 8(b). The indemnifying party shall indemnify and hold harmless the indemnified party from and against any and all losses, claims, damages, liabilities and judgments by reason of any settlement of any action effected with (i) its written consent, or (ii) effected without its written consent if the settlement is entered into more than 20 Business Days after the indemnifying party received a request from the indemnified party for reimbursement for the fees and expenses of counsel (in any case where such fees and expenses are at the expense of the indemnifying party) and, prior to the date of such settlement, the indemnifying party has failed to comply with such reimbursement request. No indemnifying party shall, without the prior written consent of the indemnified party (which consent shall not be unreasonably withheld), effect any settlement or compromise of, or consent to the entry of judgment with respect to, any pending or threatened action in respect of which the indemnified party is or could have been a party and indemnity or contribution may be or could have been sought hereunder by the indemnified party, unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability on claims that are or could have been 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 the indemnified party.

     (d) To the extent that the indemnification provided for in this Section 8 is unavailable to an indemnified party in respect of any losses, claims, damages, liabilities or judgments referred to therein for which such indemnification would otherwise be available pursuant to its terms, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or judgments (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors, on the one hand, and the Holders, on the other hand, from their sale of Entitled Securities, or (ii) if the allocation provided by

clause 8(d)(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 8(d)(i) above but also the relative fault of the Company and the Guarantors, on the one hand, and of the Holder, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or judgments, as well as any other relevant equitable considerations. The relative fault of the Company and the Guarantors, on the one hand, and of the Holder, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or such Guarantor, on the one hand, or by the Holder, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and judgments referred to above shall be deemed to include, subject to the limitations set forth in Section 8(c) hereof, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim.

     The Company, the Guarantors and each Holder agree that it would not be just and equitable if contribution pursuant to this Section 8(d) were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or judgments referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any matter, including any action that could have given rise to such losses, claims, damages, liabilities or judgments. Notwithstanding the provisions of this Section 8, no Holder, its directors, its officers or any Person, if any, who controls such Holder shall be required to contribute, in the aggregate, any amount in excess of the amount by which the total amount received by such Holder with respect to the sale of Entitled Securities pursuant to a Registration Statement exceeds the sum of: (i) the amount paid by such Holder for such Entitled Securities plus (ii) the amount of any damages that such Holder has otherwise paid or become liable to pay by reason of any 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 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Holders’ obligations to contribute pursuant to this Section 8(d) are several in proportion to the respective principal amount of Entitled Securities held by each Holder hereunder and not joint.

SECTION 9. RULE 144A AND RULE 144

     The Company and each Guarantor agrees with each Holder, for so long as any Entitled Securities remain outstanding and during any period in which the Company or such Guarantor (i) is not subject to Section 13 or 15(d) of the Exchange Act, to make available, upon request of any Holder, to such Holder or beneficial owner of Entitled Securities in connection with any sale thereof and any prospective purchaser of such Entitled Securities designated by such Holder or beneficial owner, the information required by Rule 144A(d)(4) under the Act in order to permit resales of such Entitled Securities pursuant to Rule 144A under the Act, and (ii) is subject to

Section 13 or 15(d) of the Exchange Act, to make all filings required thereby in a timely manner in order to permit resales of such Entitled Securities pursuant to Rule 144.

SECTION 10. MISCELLANEOUS

     (a) Remedies. The Company and the Guarantors acknowledge and agree that any failure by the Company and/or the Guarantors to comply with their respective obligations under Sections 3 and 4 hereof may result in material irreparable injury to the Purchasers or the Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any such failure, the Purchasers or any Holder may obtain such relief as may be required to specifically enforce the Company’s and the Guarantors’ obligations under Sections 3 and 4 hereof. The Company and the Guarantors further agree to waive the defense in any action for specific performance that a remedy at law would be adequate.

     (b) Free Writing Prospectus. The Company represents, warrants and covenants that it (including its agents and representatives) will not prepare, make, use, authorize, approve or refer to any “written communication” (as defined in Rule 405 under the Act) in connection with the issuance and sale of the Initial Notes and the Exchange Notes, other than (i) any communication pursuant to Rule 134, Rule 135 or Rule 135c under the Act, (ii) any document constituting an offer to sell or solicitation of an offer to buy the Initial Notes or the Exchange Notes that falls within the exception from the definition of prospectus in Section 2(a)(10)(a) of the Securities Act, or (iii) a prospectus satisfying the requirements of section 10(a) of the Securities Act or of Rule 430, Rule 430A, Rule 430B, Rule 430C or Rule 431 under the Securities Act.

     (c) No Inconsistent Agreements. The Company and the Guarantors will not, on or after the date of this Agreement, enter into any agreement with respect to their respective securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. The Company and the Guarantors have not previously entered into, nor is currently a party to, any agreement granting any registration rights with respect to their respective securities to any Person that would require such securities to be included in any Registration Statement filed hereunder. 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 and the Guarantors’ securities under any agreement in effect on the date hereof.

     (d) Amendments and Waivers. The provisions of this Agreement may not be amended, modified or supplemented, and waivers or consents to or departures from the provisions hereof may not be given unless (i) in the case of Section 5 hereof and this Section 10(d)(i), the Company has obtained the written consent of Holders of all outstanding Entitled Securities, and (ii) in the case of all other provisions hereof, the Company has obtained the written consent of Holders of a majority of the outstanding principal amount of Entitled Securities (excluding Entitled Securities held by the Company or its Affiliates). Notwithstanding the foregoing, a waiver or consent to or departure from the provisions hereof that relates exclusively to the rights of Holders whose Entitled Securities are being tendered pursuant to the Exchange Offer, and that does not affect directly or indirectly the rights of other Holders whose Entitled Securities are not being tendered pursuant to such Exchange Offer, may be given by the

Holders of a majority of the outstanding principal amount of Entitled Securities subject to such Exchange Offer.

     (e) Additional Guarantors. The Company shall cause any of its Restricted Subsidiaries (as defined in the Indenture) that becomes, prior to the consummation of the Exchange Offer, a Guarantor in accordance with the terms and provisions of the Indenture to become a party to this Agreement as a Guarantor.

     (f) Third Party Beneficiary. The Holders shall be third party beneficiaries to the agreements made hereunder between the Company and the Guarantors, on the one hand, and the Purchasers, 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 hereunder.

     (g) Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand-delivery, first-class mail (registered or certified, return receipt requested), telex, telecopier or air courier guaranteeing overnight delivery:

ANNEX A

PLAN OF DISTRIBUTION

Each broker-dealer that receives exchange notes 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 notes. 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 notes received in exchange for unregistered notes where such unregistered notes were acquired as a result of market-making activities or other trading activities. To the extent any such broker-dealer participates in the exchange offer, we have agreed that for a period of up to 180 days we will use commercially reasonable efforts to make this prospectus, as amended or supplemented, available to such broker-dealer for use in connection with any such resale, and will deliver as many additional copies of this prospectus and each amendment or supplement to this prospectus and any documents incorporated by reference in this prospectus as such broker-dealer may reasonably request.

We will not receive any proceeds from any sale of exchange notes by broker-dealers. Exchange notes received by broker-dealers for their own accounts 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 notes or a combination of these 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 notes. Any broker-dealer that resells exchange notes 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 notes may be deemed to be an “underwriter” within the meaning of the Securities Act and any profit on any such resale of exchange notes and any commissions 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.

We have agreed to pay all expenses incident to the exchange offer and will indemnify the holders of outstanding notes, including any broker-dealers, against certain liabilities, including liabilities under the Securities Act.

Annex A-1
