2. Registration Under the Securities Act.

Date and if requested by one or more Participating Broker-Dealers, remain effective until 180 days after the last Exchange Date for use by such Participating Broker-Dealers. The Company and the Guarantors shall commence the Exchange Offer for each series of Notes promptly after the Exchange Offer Registration Statement is declared effective by the SEC and use their commercially reasonable efforts to complete the Exchange Offer for such series not later than 60 days after such effective date.

After the Exchange Offer Registration Statement has become effective, the Company and the Guarantors shall commence the Exchange Offer for each series by mailing and/or electronically delivering, or by causing the mailing and/or electronic delivery of, 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, substantially the following:

(i) that such Exchange Offer is being made pursuant to this Agreement and that all Registrable Securities of such series validly tendered and not properly withdrawn will be accepted for exchange;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 and/or electronically delivered) (each, an “Exchange Date”);

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

(iv) that any Holder electing to have a Registrable Security of a series exchanged pursuant to the Exchange Offer for such series will be required to (A) surrender such Registrable Security, together with the appropriate letters of transmittal, to the institution and at the address and in the manner specified in the notice, or (B) effect such exchange otherwise in compliance with the applicable procedures of the depositary for such Registrable Security, in each case prior to the close of business on the last Exchange Date with respect to such Exchange Offer; and

(v) that any Holder of Registrable Securities of a series will be entitled to withdraw its election, not later than the close of business on the last Exchange Date with respect to the Exchange Offer for such series, by (A) sending to the institution and at the address specified in the notice, a 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 or (B) effecting such withdrawal in compliance with the applicable procedures of the depositary for the Registrable Securities.

As a condition to participating in an Exchange Offer, a Holder will be required to represent to the Company and the Guarantors that (1) any Exchange Securities to be received by it will be acquired in the ordinary course of its business, (2) at the time of the commencement of such 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, (3) it is not an “affiliate” (within the meaning of Rule 405 under the Securities Act) of the Company or either of the Guarantors, (4) if such Holder is not a broker-dealer, that it is not engaged in, and does not intend to engage in, the distribution of the Exchange Securities and (5) 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 (or, to the extent permitted by law, make available a Prospectus to purchasers) in connection with any resale of such Exchange Securities.

As soon as practicable after the last Exchange Date with respect to an Exchange Offer for Registrable Securities of a series, the Company and the Guarantors shall:

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

(ii) deliver, or cause to be delivered, to the Trustee for cancellation all Registrable Securities of such series or portions thereof so accepted for exchange by the Company and issue, and cause the Trustee to promptly authenticate and deliver to each Holder, Exchange Securities of such series equal in principal amount to the principal amount of the Registrable Securities of such series tendered by such Holder; provided that if any of the Registrable Securities are in book-entry form, the Company shall, in cooperation with the Trustee, effect the exchange of Registrable Securities in accordance with applicable book-entry procedures.

The Company and the Guarantors shall use their commercially reasonable efforts to complete each Exchange Offer as provided above and shall use reasonable best efforts to comply with the applicable requirements of the Securities Act, the Exchange Act and other applicable laws and regulations in connection with each Exchange Offer. No Exchange Offer shall be subject to any conditions, other than that the Exchange Offer does not violate any applicable law or applicable interpretations of the Staff and that no action or proceeding has been instituted or threatened in any court or by or before any governmental agency relating to the Exchange Offer which, in the Company’s judgment, could reasonably be expected to impair the Company’s ability to proceed with the Exchange Offer.

(b) In the event that (i) the Company determines that the Exchange Offer Registration provided for in Section 2(a) hereof is not available under applicable law or if applicable interpretations of the Staff do not permit the

Company and the Guarantors to effect the Exchange Offer for Registrable Securities of a series, or, if for any reason, the Company and the Guarantors do not consummate the Exchange Offer for Registrable Securities of a series by the Target Registration Date, or (ii) the Company receives a written request (a “Shelf Request”) from any Dealer Manager representing that it holds Registrable Securities of the applicable series that are or were ineligible to be exchanged in any such Exchange Offer, the Company and the Guarantors shall use their commercially reasonable efforts to cause to become effective a Shelf Registration Statement providing for the sale of all the Registrable Securities of such series by the Holders thereof; provided that (1) no Holder will be entitled to have any Registrable Securities included in any Shelf Registration Statement, or entitled to use the prospectus forming a part of such Shelf Registration Statement, until such Holder shall have delivered a completed and signed Notice and Questionnaire and provided such other information regarding such Holder to the Company as is contemplated by Section 3(b) hereof and, if necessary, the Shelf Registration Statement has been amended to reflect such information, and (2) the Company and the Guarantors shall be under no obligation to file any such Shelf Registration Statement before they are obligated to file an Exchange Offer Registration Statement pursuant to Section 2(a) hereof.

The Company and the Guarantors agree to use their commercially reasonable efforts to keep the Shelf Registration Statement continuously effective until the date on which the Securities covered thereby cease to be Registrable Securities (the “Shelf Effectiveness Period”). The Company and the Guarantors further agree to use their commercially reasonable efforts to supplement or amend the Shelf Registration Statement, the related Prospectus and any Free Writing 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 or if reasonably requested by a Participating Holder of Registrable Securities with respect to information relating to such Holder, and to use their commercially reasonable efforts to cause any such amendment to become effective, if required, and such Shelf Registration Statement, Prospectus or Free Writing Prospectus, as the case may be, to become usable as soon as thereafter practicable. The Company and the Guarantors agree to furnish to the Participating Holders copies of any such supplement or amendment promptly after its being used or filed with the SEC, as reasonably requested by the Participating Holders.

(c) The Company shall pay all Registration Expenses in connection with any registration pursuant to Section 2(a) or Section 2(b) hereof. Each Holder shall pay all underwriting discounts and commissions, brokerage 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 will not be deemed to have become effective unless it has been declared effective by the SEC. 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 or is automatically effective upon filing with the SEC as provided by Rule 462 under the Securities Act.

If a Registration Default occurs with respect to a series of Registrable Securities, the interest rate on the Registrable Securities (and only the Registrable Securities) of such series will be increased by (i) 0.25% per annum for the first 90-day period beginning on the day immediately following such Registration Default and (ii) an additional 0.25% per annum with respect to each subsequent 90-day period, in each case until and including the date such Registration Default ends, up to a maximum increase of 1.00% per annum. A Registration Default ends with respect to any Security when such Security ceases to be a Registrable Security or, if earlier, (1) in the case of a Registration Default under clause (i) of the definition thereof, when the Exchange Offer for such series is completed or when the Shelf Registration Statement covering such Registrable Securities becomes effective or (2) in the case of a Registration Default under clause (ii) of the definition thereof, when the Shelf Registration Statement again becomes effective or the Prospectus again becomes usable. If at any time more than one Registration Default has occurred and is continuing, then, until the next date that there is no Registration Default, the increase in interest rate provided for by this paragraph shall apply as if there occurred a single Registration Default that begins on the date that the earliest such Registration Default occurred and ends on the next date that there is no Registration Default.

Notwithstanding anything to the contrary in this Agreement, if the applicable Exchange Offer with respect to a series of Registrable Securities is consummated, any Holder who was, at the time such Exchange Offer was pending and consummated, eligible to exchange, and did not validly tender, or withdrew, its Securities for Exchange Securities in such Exchange Offer will not be entitled to receive any additional interest pursuant to the preceding paragraph, and such Securities will no longer constitute Registrable Securities hereunder.

(e) The Company and the Guarantors shall be entitled to suspend their obligation to file any amendment to a Shelf Registration Statement, furnish any supplement or amendment to a Prospectus included in a Shelf Registration Statement or any Free Writing Prospectus, make any other filing with the SEC that would be incorporated by reference into a Shelf Registration Statement, cause a Shelf Registration Statement to remain effective or the Prospectus or any Free Writing Prospectus usable or take any similar action (collectively, “Suspension Actions”) if there is a possible acquisition, disposition or business combination or other transaction, business development or event involving the Company, the Guarantors or any of their respective subsidiaries that may require disclosure in the Shelf Registration Statement or Prospectus and the Company or either of the Guarantors determines that such disclosure is not in the best interest of the Company, the Guarantors and their stockholders or obtaining any financial statements relating to any such acquisition or business combination required to be included in the Shelf Registration Statement or Prospectus would be impracticable. Upon the occurrence of any of the conditions described in the foregoing sentence, the Company shall give prompt notice of the delay or suspension (but not the basis thereof) to the Participating Holders. Upon the

termination of such condition, the Company shall promptly proceed with all Suspension Actions that were delayed or suspended and, if required, shall give prompt notice to the Participating Holders of the cessation of the delay or suspension (but not the basis thereof).

(f) Without limiting the remedies available to the Dealer Managers and the Holders, the Company and the Guarantors acknowledge that any failure by the Company or the Guarantors to comply with their obligations under Section 2(a) and Section 2(b) hereof may result in material irreparable injury to the Dealer Managers 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 Dealer Managers or any Holder may seek to specifically enforce the Company’s and the Guarantors’ obligations under Section 2(a) and Section 2(b) hereof; provided, however, that with respect to any Registration Default which occurs prior to the 60th day after the Effective Time, payment of additional interest as described in Section 2(d) hereof shall be the sole and exclusive remedy in respect of such Registration Default.

3. Registration Procedures.

(xvi) in the case of a Shelf Registration, cause all Registrable Securities covered thereby to be listed on any securities exchange or any automated quotation system on which similar senior unconvertible debt securities issued by the Company are then listed if requested by the Holders of a majority in principal amount of the Registrable Securities covered by the Shelf Registration Statement, to the extent such Registrable Securities satisfy applicable listing requirements;

(xvii) if reasonably requested by any Participating Holder, promptly include or incorporate by reference in a Prospectus supplement or post-effective amendment such information with respect to such Participating Holder as such Participating Holder reasonably requests to be included therein, based upon a reasonable belief that such information is required to be included therein or is necessary to make the information about such Participating Holder not misleading, and make all required filings of such Prospectus supplement or such post-effective amendment as soon as reasonably practicable after the Company has received notification of the matters to be so included in such filing; and

(xviii) in the case of a Shelf Registration, enter into such customary agreements and take all such other actions in connection therewith (including those requested by the Holders of a majority in principal amount of the Registrable Securities covered by the Shelf Registration Statement) in order to expedite or facilitate the disposition of such Registrable Securities including, but not limited to, an Underwritten Offering and in such connection, (1) provided that the Participating Holders’ representations and warranties are of the substance and scope as are customarily made by selling securityholders to underwriters in underwritten offerings, to the extent possible, make such representations and warranties to the Participating Holders and any Underwriters of such Registrable Securities with respect to the business of the Company and its subsidiaries and the Registration Statement, Prospectus, any Free Writing Prospectus and documents incorporated by reference or deemed incorporated by reference, if any, in each case, in form, substance and scope as are customarily made by issuers to underwriters in underwritten offerings and consistent with the applicable representations and warranties in the Dealer Manager Agreement and confirm the same if and when requested, (2) obtain opinions of counsel to the Company and the Guarantors (which counsel and opinions, in form, scope and substance, shall be reasonably satisfactory to the Participating Holders and such Underwriters and their respective counsel) addressed to the Underwriter of Registrable Securities, covering the matters customarily covered in opinions requested in underwritten offerings and consistent with the opinions delivered pursuant to the Dealer Manager Agreement, provided that, if required by the Underwriter, counsel for the Participating Holders shall provide an opinion to the Underwriter covering the matters customarily covered in opinions requested from selling securityholders by

underwriters in underwritten offerings, in connection with an Underwritten Offering (3) in connection with an Underwritten Offering, obtain “comfort” letters from the independent registered public accountants of the Company and the Guarantors (and, if necessary, any other registered public accountant of any subsidiary of the Company or the Guarantors, or of any business acquired by the Company or the Guarantors for which financial statements and financial data are or are required to be included in the Registration Statement) addressed to the Underwriter of Registrable Securities, such letters to be in customary form and covering matters of the type customarily covered in “comfort” letters in connection with underwritten offerings, including but not limited to financial information contained in any preliminary prospectus, Prospectus or Free Writing Prospectus and (4) in connection with an Underwritten Offering, deliver such documents and certificates as may be reasonably requested by the Underwriters, and which are customarily delivered in underwritten offerings, to evidence the continued validity of the representations and warranties made pursuant to clause (1) above and to evidence compliance with any customary conditions contained in an underwriting agreement.

(b) In the case of a Shelf Registration Statement, the Company may require, as a condition to including such Holder’s Registrable Securities in such Shelf Registration Statement, each Holder of Registrable Securities to furnish to the Company a Notice and Questionnaire and such other information regarding such Holder and the proposed disposition by such Holder of such Registrable Securities and other documentation necessary to effectuate the proposed disposition as the Company and the Guarantors may from time to time reasonably request in writing and require such Holder to agree in writing to be bound by all provisions of this Agreement applicable to such Holder. Each Holder of Registrable Securities as to which any Shelf Registration is being effected agrees to furnish promptly to the Company all information required to be disclosed so that the information previously furnished to the Company by such Holder is not materially misleading and does not omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made.

(c) Each Participating Holder agrees that, upon receipt of any notice from the Company and the Guarantors of the happening of any event of the kind described in Section 3(a)(vi)(2) or Section 3(a)(vi)(4) hereof, such Participating Holder will forthwith discontinue disposition of Registrable Securities pursuant to the Shelf Registration Statement until such Participating Holder’s receipt of the copies of the supplemented or amended Prospectus and any Free Writing Prospectus contemplated by Section 3(a)(xi) hereof and, if so directed by the Company and the Guarantors, such Participating Holder will deliver to the Company and the Guarantors all copies in its possession, other than permanent file copies then in such Participating Holder’s possession, of the Prospectus and

any Free Writing Prospectus covering such Registrable Securities that is current at the time of receipt of such notice.

(d) If the Company and the Guarantors shall give any notice to suspend the disposition of Registrable Securities pursuant to a Registration Statement, the Company and the Guarantors shall extend the period during which such 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 notice to and including the date when the Holders of such Registrable Securities shall have received copies of the supplemented or amended Prospectus or any Free Writing Prospectus necessary to resume such dispositions or notice that such amendment or supplement is not necessary; provided, however, that no such extension shall be made in the case where such suspension is solely a result the Company’s compliance with Section 3(b) or any other suspension at the request of a Holder.

(e) The Participating Holders who desire to do so may sell such Registrable Securities in an Underwritten Offering. In any such Underwritten Offering, the investment bank or investment banks and manager or managers (each an “Underwriter”) that will administer the offering will be selected by the Holders of a majority in principal amount of the Registrable Securities included in such offering, subject in each case to consent by the Company (which shall not be unreasonably withheld or delayed so long as such bank or manager is internationally recognized as a underwriter of debt securities offerings).

(f) No Holder of Registrable Securities may participate in any Underwritten Offering hereunder unless such Holder (i) agrees to sell such Holder’s Registrable Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements.

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 an 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 Company and the Guarantors understand that it is the Staff’s position that if the Prospectus contained in an 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 (or, to the extent permitted by law, made available to purchasers) 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.

(b) In light of the above, and notwithstanding the other provisions of this Agreement, the Company and the Guarantors agree to amend or supplement the Prospectus contained in the Exchange Offer Registration Statement for a period of up to 180 days after the last Exchange Date (as such period may be extended pursuant to Section 3(d) hereof), if requested 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 above. The Company and the Guarantors further agree that Participating Broker-Dealers shall be authorized to deliver such Prospectus (or, to the extent permitted by law, make available) during such period in connection with the resales contemplated by this Section 4.

(c) The Dealer Managers shall have no liability to the Company, the Guarantors or any Holder with respect to any request that they may make pursuant to Section 4(b) hereof.

5. Indemnification and Contribution.

(a) The Company and, if the Guarantees are registered under any effective Registration Statement, the Guarantors each will, jointly and severally, indemnify and hold harmless each Dealer Manager and each Holder, their respective directors, officers and employees, each Person, if any, who controls any Dealer Manager or any Holder within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of any Dealer Manager within the meaning of Rule 405 under the Securities Act (any of the foregoing, an “Indemnified Person”), from and against any and all losses, claims, damages and liabilities, joint or several, to which such Dealer Manager, Holder, director, officer, employee, controlling Person or affiliate may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Registration Statement, any Prospectus as amended or supplemented, any Free Writing Prospectus or any “issuer information” (“Issuer Information”) filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary in order to make the statements therein in the light of the circumstances under which they were made not misleading, and will reimburse each such Dealer Manager, Holder, director, officer, employee, controlling Person or affiliate for any legal or other expenses reasonably incurred by such Dealer Manager, Holder, director, officer, employee, controlling Person or affiliate in

connection with investigating or defending any such loss, damage, liability, action or claim as such expenses are incurred; provided, however, that the Company and the Guarantors shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Registration Statement, any Prospectus as amended or supplemented, any Free Writing Prospectus or any Issuer Information in reliance upon and in conformity with information relating to any Dealer Manager or any Holder furnished to the Company and the Guarantors in writing by such Dealer Manager through the Representatives or by such Holder expressly for use therein.

(b) Each Holder will, severally and not jointly, indemnify and hold harmless the Company, the Guarantors, the Dealer Managers and the other selling Holders, the directors, officers and employees of the Company, the Guarantors, and the Dealer Managers, each Person, if any, who controls the Company, the Guarantors, any Dealer Manager and any other selling Holder (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and each affiliate of any Dealer Manager within the meaning of Rule 405 under the Securities Act against any losses, claims, damages or liabilities to which the Company, the Guarantors, or such Dealer Manager, other selling Holder, director, officer, employee, controlling Person or affiliate may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) that arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement, any Prospectus as amended or supplemented or any Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary in order to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any Registration Statement, any Prospectus as amended or supplemented or any Free Writing Prospectus in reliance upon and in conformity with written information relating to such Holder furnished to the Company or the Guarantors by such Holder; and each Holder will reimburse the Company, the Guarantors, and such Dealer Manager, other selling Holder, director, officer, employee, controlling Person and affiliate in connection with investigating, or defending any such loss, damage, liability, action or claim as such expenses are incurred, but only with reference to information relating to such Holder furnished to the Company in writing by such Holder expressly for use in any Registration Statement, any Prospectus or any Free Writing Prospectus.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party except to the extent such omission materially prejudices the indemnifying party. In case

any such action shall be brought against any indemnified party, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation.

(d) To the extent the indemnification provided for in paragraph (a) or (b) of this Section 5 is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein (or actions in respect thereof), then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors from the offering of the Securities or Exchange Securities, on the one hand, and the Holders from receiving Securities or Exchange Securities registered under the Securities Act, on the other. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnifying party failed to give notice required under paragraph (c) of this Section 5, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only the relative benefits but also the relative fault of the Company and the Guarantors on the one hand and the Holders on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative fault of the Company and the Guarantors 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 Company or the Guarantors on the one hand or such Holder on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) The Company, the Guarantors and the Holders agree that it would not be just or 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 reasonably incurred by

such Indemnified Person in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 5, no Holder shall 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. The Holders’ obligations to contribute pursuant to this Section 5 are several and not joint.

(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 Dealer Managers or any Holder, any Person controlling any Dealer Manager or any Holder or any affiliate of any Dealer Manager, or by or on behalf of the Company, the Guarantors, their officers or directors or any Person controlling the Company or the Guarantors, (iii) acceptance of any of the Exchange Securities and (iv) any sale of Registrable Securities pursuant to a Shelf Registration Statement. Notwithstanding anything in this Section 5 to the contrary, the Guarantors shall have no liability under this Section 5 to any indemnified party if the Guarantees have been terminated in accordance with the terms of the Indenture prior to the time any Registration Statement has become effective.

6. General.

(a) No Inconsistent Agreements. The Company and the Guarantors represent, warrant and agree that neither the Company nor the Guarantors have 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 Company has 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. Each Holder of Registrable Securities outstanding at the time of any such amendment, modification, supplement, waiver or consent thereafter shall be bound by any such amendment, modification, supplement, waiver or consent effected pursuant to this Section 6(b), whether or not any notice, writing or marking indicating such amendment, modification, supplement, waiver or consent appears on the Registrable Securities or is delivered to such Holder. Each Holder may waive compliance with respect to any obligation of the Company or the Guarantors under this Agreement as it may apply or be enforced by such particular Holder.

(c) Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand-delivery, registered first-class mail, 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 Dealer Managers, the address set forth in the Dealer Manager Agreement; (ii) if to the Company or the Guarantors, initially at the applicable addresses set forth in the Dealer Manager Agreement and thereafter at such other address(es), 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 Dealer Manager 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; three Business Days after being deposited in the mail, postage prepaid, if mailed; when receipt is acknowledged, if telecopied; and on the next Business Day if timely delivered to an air courier guaranteeing overnight delivery.

(d) Majority of Holders. Whenever an action or determination under this Agreement requires a majority of the aggregate principal amount of the applicable holders, in determining such majority, if the Company shall issue any additional Securities under the Indenture prior to consummation of the Exchange Offer or, if applicable, the effectiveness of any Shelf Registration Statement, then such additional Securities and the Registrable Securities to which this Agreement relates shall be treated together as one class for purposes of determining whether the consent or approval of Holders of a specified percentage of Registrable Securities has been obtained.

(e) 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 Dealer Manager 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 Dealer Managers (in their capacity as Dealer Managers) 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.

(f) Third Party Beneficiaries. Each Holder shall be a third party beneficiary to the agreements made hereunder between the Company and the Guarantors, on the one hand, and the Dealer Managers, 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 two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument, and shall become effective when one or more counterparts have been signed by each of the parties and delivered (by telecopy, electronic delivery or otherwise) to the other parties. Signatures to this Agreement transmitted by facsimile transmission, by electronic mail in “portable document format” (“.pdf”) form, or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document, will have the same effect as physical delivery of the paper document bearing the original signature.

(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, and any claim, controversy or dispute arising under or related to this Agreement, shall be governed by and construed in accordance with the laws of the State of New York.

(j) Entire Agreement; Severability. 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 Company, the Guarantors and the Dealer Managers 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.

7. Creation and Termination of Obligations of Guarantors.

Notwithstanding any other provisions of this Agreement, neither Cigna nor Express Scripts shall have any obligations under this Agreement until such time as such entity shall have become a guarantor pursuant to the terms of the Indenture.

Further, it is acknowledged that the Guarantees will terminate pursuant to the terms of the Indenture and, accordingly, it is agreed that, concurrently with any termination of the Guarantees, all obligations of the Guarantors under this Agreement shall automatically terminate and all references to the Guarantors in this Agreement shall be deemed to be eliminated.

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