The Issuers shall commence the Exchange Offer by mailing the related Prospectus, appropriate letters of transmittal and other accompanying documents to each Holder stating, in addition to such other disclosures as are required by applicable law,

(i) that the Exchange Offer is being made pursuant to this Agreement and that all Registrable Securities validly tendered and not properly withdrawn will be accepted for exchange;

(ii) the dates of acceptance for exchange (which shall be a period of at least 20 Business Days from the date such notice is mailed) (the “Exchange Dates”);

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

(iv) that any Holder electing to have a Registrable Security exchanged pursuant to the Exchange Offer will be required to surrender such Registrable Security, together with the appropriate letters of transmittal, to the institution and at the address (located in the Borough of Manhattan, The City of New York) and in the manner specified in the notice, prior to the close of business on the last Exchange Date; and

(v) that any Holder will be entitled to withdraw its election, not later than the close of business on the last Exchange Date, by sending to the institution and at the address (located in the Borough of Manhattan, The City of New York) specified in the notice, a telegram, telex, facsimile transmission or letter setting forth the name of such Holder, the principal amount of Registrable Securities delivered for exchange and a statement that such Holder is withdrawing its election to have such Securities exchanged.

As a condition to participating in the Exchange Offer, a Holder will be required to represent to the Issuers that (i) any Exchange Securities to be received by it will be acquired in the ordinary course of its business, (ii) at the time of the commencement of the Exchange Offer it has no arrangement or understanding with any Person to participate in the distribution (within the meaning of the Securities Act) of the Exchange Securities in violation of the provisions of the Securities Act, (iii) it is not an “affiliate” (within the meaning of Rule 405 under Securities Act) of the Company or any Guarantor and (iv) if such Holder is a broker-dealer that will receive Exchange Securities for its own account in exchange for

Registrable Securities that were acquired as a result of market-making or other trading activities, then such Holder will deliver a Prospectus in connection with any resale of such Exchange Securities.

As soon as practicable after the last Exchange Date, the Issuers shall:

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

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

The Issuers shall use their reasonable best efforts to complete the Exchange Offer as provided above and shall comply with the applicable requirements of the Securities Act, the Exchange Act and other applicable laws and regulations in connection with the Exchange Offer. The Exchange Offer shall not be subject to any conditions, other than that the Exchange Offer does not violate any applicable law or applicable interpretations of the Staff.

(b) In the event that (i) the Issuers determine that the Exchange Offer Registration provided for in Section 2(a) above is not available or may not be completed as soon as practicable after the last Exchange Date because it would violate any applicable law or applicable interpretations of the Staff, (ii) the Exchange Offer is not for any other reason completed by the 240th day following the Closing Date or (iii) any Holder notifies the Issuers on or prior to the 20th Business Day following the consummation of the Exchange Offer that (A) it is not permitted under law or SEC policy to participate in the Exchange Offer, (B) it cannot publicly resell the Exchange Securities that it acquires in the Exchange Offer without delivering a Prospectus, and the Prospectus contained in the Exchange Offer Registration Statement is not appropriate or available for resales by the Holder or (C) it is a broker-dealer and holds Registrable Securities that it has not exchanged and that it acquired directly from the Issuers or one of their affiliates, then in addition to or in lieu of conducting the Exchange Offer, the Issuers shall be required to file a Shelf Registration Statement with the SEC to cover resales of the Registrable Securities or the Exchange Securities, as the case may be. In that case, the Issuers will use their reasonable best efforts to (a) file the Shelf Registration Statement by the 45th day after they become obligated to make the filing, (b) cause the Shelf Registration Statement to become effective by the 60th day after they become obligated to make the filing and (c) maintain the effectiveness of the Shelf Registration Statement for two years or such lesser period after which all of the Notes registered therein have been sold or can be resold without limitation under the Securities Act (the “Shelf Effectiveness Period”). In the event that the Issuers are required to file a Shelf Registration Statement solely as a result of the matters referred to in clause (ii) of this paragraph, but the Exchange Offer is subsequently

completed, upon consummation of the Exchange Offer, the Issuers will no longer be required to file, have declared effective or continue the effectiveness of the Shelf Registration Statement pursuant to such clause (ii) (without prejudice to its obligations under clause (i) or (iii) of this paragraph). In the event that the Issuers are required to file a Shelf Registration Statement solely as a result of the matters referred to in clause (iii) of this paragraph, the Issuers shall use their reasonable best efforts to file and have declared effective by the SEC both an Exchange Offer Registration Statement pursuant to Section 2(a) with respect to all Registrable Securities and a Shelf Registration Statement (which may be a combined Registration Statement with the Exchange Offer Registration Statement) with respect to offers and sales of Registrable Securities held by any such Holder that has notified the Issuers pursuant to such clause (iii) after completion of the Exchange Offer.

The Issuers agree to use their reasonable best efforts to keep the Shelf Registration Statement continuously effective until the earliest of (i) two years from the date the Shelf Registration Statement is declared effective by the SEC, (ii) the expiration of the period referred to in Rule 144(k) under the Securities Act with respect to the Registrable Securities or (iii) the last day of the Shelf Effectiveness Period. The Issuers further agree to supplement or amend the Shelf Registration Statement and the related Prospectus if required by the rules, regulations or instructions applicable to the registration form used by the Company for such Shelf Registration Statement or by the Securities Act or by any other rules and regulations thereunder for shelf registration, or if reasonably requested by a Holder of Registrable Securities with respect to information relating to such Holder, and to use their reasonable best efforts to cause any such amendment to become effective and such Shelf Registration Statement and Prospectus to become usable as soon as practicable thereafter. The Company and the Guarantors agree to furnish to the Holders of Registrable Securities copies of any such supplement or amendment promptly after its being used or filed with the SEC.

(c) The Issuers shall pay all Registration Expenses in connection with the registration pursuant to Section 2(a) and Section 2(b) hereof. Each Holder shall pay all underwriting discounts and commissions and transfer taxes, if any, relating to the sale or disposition of such Holder’s Registrable Securities pursuant to the Shelf Registration Statement.

(d) An Exchange Offer Registration Statement pursuant to Section 2(a) hereof or a Shelf Registration Statement pursuant to Section 2(b) hereof will not be deemed to have become effective unless it has been declared effective by the SEC.

In the event that (i) the Exchange Offer is not completed by the 240th day following the Closing Date, (ii) the Shelf Registration Statement, if required hereby, is not filed by the date specified in Section 2(b) hereof, (iii) the Exchange Offer Registration Statement is not declared effective by the 210th day following the Closing Date, (iv) the Shelf Registration Statement, if required hereby, is not declared effective by the date specified in Section 2(b) hereof, or (v) the Exchange Offer Registration Statement or the Shelf Registration Statement is declared effective, but thereafter, except as specifically set forth herein, ceases to be

effective or usable in connection with the Exchange Offer or resales of any Registrable Securities registered under the Shelf Registration Statement (each such event referred to in clauses (i) through (v) a “Registration Default”), the interest rate on the Registrable Securities will be increased by 0.25% per annum for the first 90-day period immediately following one or more Registration Defaults and (ii) an additional 0.25% per annum with respect to each subsequent 90-day period, up to a maximum of 1.00% per annum of additional interest, until all Registration Defaults are cured, at which time the interest rate on the Registrable Securities will revert to the original interest rate on the Notes. A Registration Default referred to in Section 2(b)(v) shall be deemed not to have occurred and be continuing in relation to the Exchange Offer 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 the Exchange Offer Registration Statement to incorporate annual audited financial information with respect to the Issuers 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 Issuers that would need to be described in such Exchange Offer Registration Statement or the related prospectus and (ii) in the case of clause (y), the Issuers are proceeding promptly and in good faith to amend or supplement the Exchange Offer Registration Statement and related prospectuses to describe such events; provided, however, if such Registration Default occurs for more than 30 days, the interest rate on the Notes shall be increased in accordance with the preceding sentence and shall be payable in accordance with the above from the day such Registration Default actually occurs (without giving effect to the text preceding this proviso) until such Registration Default is actually cured.

(e) Without limiting the remedies available to the Initial Purchaser and the Holders, the Issuers acknowledge that any failure by the Issuers to comply with their obligations under Section 2(a) and Section 2(b) hereof may result in irreparable injury to the Initial Purchaser or the Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any such failure, the Initial Purchaser or any Holder may obtain such relief as may be required to specifically enforce the Issuers’ obligations under Section 2(a) and Section 2(b) hereof.

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

In the case of a Shelf Registration Statement, the Company may require each Holder of Registrable Securities to furnish to the Company such information regarding such Holder and the proposed disposition by such Holder of such Registrable Securities as the Issuers may from time to time reasonably request in writing. The Issuers may exclude from such Shelf Registration Statement the Registrable Securities of any Holder that fails to furnish such information within a reasonable time after receiving such a request.

In the case of a Shelf Registration Statement, each Holder of Registrable Securities agrees that, upon receipt of any notice (a “Blackout Notice”) from the Issuers of (i) the

happening of any event of the kind described in Section 3(e)(iii), 3(e)(v) or 3(e)(vi) hereof or (ii) the Issuers’ determination to suspend use of the Prospectus to avoid premature public disclosure of a pending corporate transaction, including pending acquisitions or divestitures of assets, mergers and combinations and similar events, such Holder will forthwith discontinue disposition of Registrable Securities pursuant to a Registration Statement until such Holder’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 3(i) hereof (and, if applicable, the effectiveness of the post-effective amendment described in Section 3(e)(vi) hereof) and, if so directed by the Issuers, such Holder will deliver to the Issuers all copies in its possession, other than permanent file copies then in such Holder’s possession, of the Prospectus covering such Registrable Securities that is current at the time of receipt of such notice. If the Issuers shall give any such Blackout Notice, the Issuers shall, subject to Section 2(b) hereof, extend the period during which the Registration Statement shall be maintained effective pursuant to this Agreement by the number of days during the period from and including the date of the giving of such Blackout Notice to and including the date when the Holders shall have received copies of the supplemented or amended Prospectus necessary to resume such dispositions (the “Blackout Period”). The Issuers may give any such notice only twice during any 365-day period and any such suspensions shall not exceed 30 days for each suspension and there shall not be more than two suspensions in effect during any 365-day period. The interest rate on the Notes shall not be increased in accordance with Section 2(d) hereof during a Blackout Period.

The Holders of Registrable Securities covered by a Shelf Registration Statement who desire to do so may sell such Registrable Securities in an Underwritten Offering. In any such Underwritten Offering, the investment banker or investment bankers and manager or managers (the “Underwriters”) that will administer the offering will be selected by the Majority Holders of the Registrable Securities included in such offering.

4. Participation of Broker-Dealers in Exchange Offer. (a) The Staff has taken the position that any broker-dealer that receives Exchange Securities for its own account in the Exchange Offer in exchange for Securities that were acquired by such broker-dealer as a result of market-making or other trading activities (a “Participating Broker-Dealer”) may be deemed to be an “underwriter” within the meaning of the Securities Act and must deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such Exchange Securities.

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

include a statement to such effect in the plan of distribution section of the Exchange Offer Registration Statement.

(b) In light of the above, and notwithstanding the other provisions of this Agreement, the Issuers agree to amend or supplement the Prospectus contained in the Exchange Offer Registration Statement, as would otherwise be contemplated by Section 3(i), for a period of up to 180 days after the last Exchange Date (as such period may be extended pursuant to the penultimate paragraph of Section 3 of this Agreement), if requested by the Initial Purchaser or by one or more Participating Broker-Dealers, in order to expedite or facilitate the disposition of any Exchange Securities by Participating Broker-Dealers consistent with the positions of the Staff recited in Section 4(a) above. The Issuers further agree that Participating Broker-Dealers shall be authorized to deliver such Prospectus during such period in connection with the resales contemplated by this Section 4.

(c) The Initial Purchaser shall have no liability to the Company, any Guarantor or any Holder with respect to any request that they may make pursuant to Section 4(b) above.

5. Indemnification and Contribution. (a) The Issuers, jointly and severally, agree to indemnify and hold harmless the Initial Purchaser and each Holder, their respective affiliates, directors and officers and each Person, if any, who controls the Initial Purchaser or any Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or any Prospectus or any 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, and will reimburse, as incurred, the Initial Purchaser and each Holder for any legal or other expenses reasonably incurred by the Initial Purchaser or such Holder in connection with investigating, defending against or appearing as a third-party witness in connection with any such loss, claim, damage, liability or action, except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to the Initial Purchaser or any Holder furnished to the Company in writing through Wachovia Capital Markets, LLC or any selling Holder expressly for use therein. In connection with any Underwritten Offering permitted by Section 3, the Issuers, jointly and severally, will also indemnify the Underwriters, if any, selling brokers, dealers and similar securities industry professionals participating in the distribution, their respective affiliates and each Person who controls such Persons (within the meaning of the Securities Act and the Exchange Act) to the same extent as provided above with respect to the indemnification of the Holders, if requested in connection with any Registration Statement.

(b) Each Holder agrees, severally and not jointly, to indemnify and hold harmless the Company, the Guarantors, the Initial Purchaser and the other selling Holders, their respective affiliates, the directors of the Issuers, each officer of the Issuers who signed the Registration Statement and each Person, if any, who controls the Company, the Guarantors, any Initial Purchaser and any other selling Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Holder furnished to the Company in writing by such Holder expressly for use in any Registration Statement and any Prospectus.

(c) If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any Person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such Person (the “Indemnified Person”) shall promptly notify the Person against whom such

indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under this Section 5 except to the extent that it has been materially prejudiced by such failure. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 5 that the Indemnifying Person may designate in such proceeding and shall pay the reasonable fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding, be liable for the fees and expenses of more than one firm (in addition to one local counsel in each applicable jurisdiction) for the Initial Purchasers and one firm (in addition to one local counsel in each applicable jurisdiction) for all other Indemnified Persons and that all such reasonable fees and expenses shall be reimbursed as they are incurred. Any such separate firm (x) for the Initial Purchaser, its affiliates, directors and officers and any control Persons of such Initial Purchaser shall be designated in writing by Wachovia Capital Markets, LLC, (y) for any Holder, its affiliates, directors and officers and any control Persons of such Holder shall be designated in writing by the Majority Holders and (z) in all other cases shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (A) includes an unconditional release of such Indemnified Person, in form and substance

reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Issuers from the offering of the Securities and the Exchange Securities, on the one hand, and by the Holders from receiving Securities or Exchange Securities registered under the Securities Act, on the other hand, or (ii) if the allocation provided by 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) but also the relative fault of the Issuers on the one hand and the Holders on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault of the Issuers on the one hand and the Holders on the other 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 by the Holders and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) The Issuers and the Holders agree that it would not be just and equitable if contribution pursuant to this Section 5 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 paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 5, in no event shall a Holder be required to contribute any amount in excess of the amount by which the total price at which the Securities or Exchange Securities sold by such Holder exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

(f) The remedies provided for in this Section 5 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity.

(g) The indemnity and contribution provisions contained in this Section 5 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of the Initial Purchaser or any Holder, their respective affiliates or any Person controlling the Initial Purchaser or any Holder, or by or on behalf of the Issuers, their respective affiliates or the officers or directors of or any Person controlling the Issuers, (iii) acceptance of any of the Exchange Securities and (iv) any sale of Registrable Securities pursuant to a Shelf Registration Statement.

6. General.

(a) No Inconsistent Agreements. The Issuers represent, warrant and agree that (i) 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 any other outstanding securities issued or guaranteed by the Company or any Guarantor under any other agreement and (ii) neither the Company nor any Guarantor has entered into, or on or after the date of this Agreement will enter into, any agreement that is inconsistent with the rights granted to the Holders of Registrable Securities in this Agreement or otherwise conflicts with the provisions hereof.

(b) Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given unless the Issuers have obtained the written consent of Holders of at least a majority in aggregate principal amount of the outstanding Registrable Securities affected by such amendment, modification, supplement, waiver or consent; provided that no amendment, modification, supplement, waiver or consent to any departure from the provisions of Section 5 hereof shall be effective as against any Holder of Registrable Securities unless consented to in writing by such Holder. Any amendments, modifications, supplements, waivers or consents pursuant to this Section 6(b) shall be by a writing executed by each of the parties hereto.

(c) Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand-delivery, registered first-class mail, telex, telecopier, or any courier guaranteeing overnight delivery (i) if to a Holder, at the most current address given by such Holder to the Company by means of a notice given in accordance with the provisions of this Section 6(c), which address initially is, with respect to the Initial Purchaser, the address set forth in the Purchase Agreement; (ii) if to the Issuers, initially at the address of the Company set forth in the Purchase Agreement and thereafter at such other address, notice of which is given in accordance with the provisions of this Section 6(c); and (iii) to such other persons at their respective addresses as provided in the Purchase Agreement and thereafter at such other address, notice of which is given in accordance with the provisions of this Section 6(c). All such notices and communications shall be deemed to have been duly given at the time delivered by hand, if personally delivered; five Business Days after being deposited in the mail, postage prepaid, if mailed; when delivery confirmation is received, if telexed; when receipt is acknowledged, if telecopied; and on the next Business Day if timely

delivered to an air courier guaranteeing overnight delivery. Copies of all such notices, demands or other communications shall be concurrently delivered by the Person giving the same to the Trustee, at the address specified in the Indenture.

(d) Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors, assigns and transferees of each of the parties, including, without limitation and without the need for an express assignment, subsequent Holders; provided that nothing herein shall be deemed to permit any assignment, transfer or other disposition of Registrable Securities in violation of the terms of the Purchase Agreement or the Indenture. If any transferee of any Holder shall acquire Registrable Securities in any manner, whether by operation of law or otherwise, such Registrable Securities shall be held subject to all the terms of this Agreement, and by taking and holding such Registrable Securities such Person shall be conclusively deemed to have agreed to be bound by and to perform all of the terms and provisions of this Agreement and such Person shall be entitled to receive the benefits hereof. The Initial Purchaser (in its capacity as Initial Purchaser) shall have no liability or obligation to the Company or the Guarantors with respect to any failure by a Holder to comply with, or any breach by any Holder of, any of the obligations of such Holder under this Agreement.

(e) Purchases and Sales of Securities. The Issuers shall not, and shall use their reasonable best efforts to cause their affiliates (as defined in Rule 405 under the Securities Act) not to, purchase and then resell or otherwise transfer any Registrable Securities.

(f) Third Party Beneficiaries. Each Holder shall be a third party beneficiary to the agreements made hereunder between the Issuers, on the one hand, and the Initial Purchaser, on the other hand, and shall have the right to enforce such agreements directly to the extent it deems such enforcement necessary or advisable to protect its rights or the rights of other Holders hereunder.

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

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

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

(j) Miscellaneous. This Agreement contains the entire agreement between the parties relating to the subject matter hereof and supersedes all oral statements and prior writings with respect thereto. If any term, provision, covenant or restriction contained in this

Agreement is held by a court of competent jurisdiction to be invalid, void or unenforceable or against public policy, the remainder of the terms, provisions, covenants and restrictions contained herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated. The Issuers and the Initial Purchaser shall endeavor in good faith negotiations to replace the invalid, void or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, void or unenforceable provisions.

IN WITNESS WHEREOF, the parties have executed this Agreement as of the date first written above.
