In connection with the offering of the Offered Securities, until the Representatives shall have notified the Issuer and the other Underwriters of the completion of the resale of the Offered Securities, neither the Guarantor, its subsidiaries nor any of their affiliates will, either alone or with one or more other persons, bid for or purchase for any account in which it or any of its affiliates has a beneficial interest any Offered Securities or attempt to induce any person to purchase any Offered Securities; and neither it nor any of its affiliates will make bids or purchases for the purpose of creating actual, or apparent, active trading in, or of raising the price of, the Offered Securities.

(l)  Eligibility for Clearance. The Issuer and the Guarantor will reasonably assist the Underwriters to permit the Offered Securities to be eligible for clearance and settlement through the facilities of DTC.

4.  Free Writing Communications.

Any such free writing prospectus consented to by the Issuer, the Guarantor and the Representatives (including the term sheet in the form of Annex I to Schedule B hereto) is hereinafter referred to as a “Permitted Free Writing Prospectus.” Each of the Issuer and the Guarantor represents that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including timely Commission filing where required, legending and record keeping.

The Representatives may in their sole discretion waive on behalf of the Underwriters compliance with any conditions to the obligations of the Underwriters hereunder, whether in respect of a Closing Date or otherwise.

6.  Indemnification and Contribution.

(a)  Indemnification of the Underwriters. The Issuer, the Guarantor and New Parent will indemnify and hold harmless each Underwriter, its partners, members, directors, officers, employees, agents, affiliates and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each, an “Indemnified Party”), against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject, under the Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of the Registration Statement at any time, any Statutory Prospectus as of any time, the General Disclosure Package, the Final Prospectus or any Issuer Free Writing Prospectus, including any investor presentations or any “road show” used in connection with the offering and sale of the Offered Securities, or arise out of or are based upon the omission or alleged omission of 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, and will reimburse each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending against any loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Indemnified Party is a party thereto), whether threatened or commenced, and in connection with the enforcement of this provision with respect to any of the above as such expenses are incurred; provided, however, that the Issuer, the Guarantor and New Parent will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Issuer, the Guarantor or New Parent by any Underwriter through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (b) below.

(b)  Indemnification of the Issuer, the Guarantor and New Parent. Each Underwriter will severally and not jointly indemnify and hold harmless each of the Issuer, the Guarantor and New Parent and each of their respective directors, officers, employees, agents and affiliates and each person, if any, who controls the Issuer, the Guarantor or New Parent within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each, an “Underwriter Indemnified Party”), against any and all losses, claims, damages or liabilities to which such Underwriter Indemnified Party may become subject, under the Act, the Exchange Act, or other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement at any time, any Statutory Prospectus at any time, the Final Prospectus or any Issuer Free Writing Prospectus or arise out of or are based upon the omission or the alleged omission of a material fact required to be stated therein or necessary 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 reliance upon and in conformity with written information furnished to the Issuer, the Guarantor or New Parent by such Underwriter through the Representatives specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by such Underwriter Indemnified Party in connection with investigating or defending against any such loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Underwriter Indemnified Party is a party thereto), whether threatened or commenced, based upon any such untrue statement or omission, or any such alleged untrue statement or omission as such expenses are incurred, it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Final Prospectus furnished on behalf of each Underwriter: the information contained in the first and second sentences of the fifth paragraph, the third and fourth sentences in the eighth paragraph, the eleventh paragraph and the twelfth paragraph, in each case under the caption “Underwriting.”

(c)  Actions against Parties; Notification. Promptly after receipt by an indemnified party under this Section 6 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled

-15-

to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section 6 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. In any such proceeding, any indemnified party 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 party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the contrary; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party 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 party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party 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 party shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all indemnified parties, and that all such fees and expenses shall be reimbursed as they are incurred. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to or an admission of fault, culpability or failure to act by or on behalf of any indemnified party. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent(which consent shall not be unreasonably withheld), but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify each indemnified party from and against any loss or liability by reason of such settlement or judgment.

(d)  Contribution. If the indemnification provided for in this Section 6 is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Issuer and the Guarantor on the one hand and the Underwriters on the other from the offering of the Offered Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Issuer and the Guarantor on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Issuer and the Guarantor on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Issuer and the Guarantor bear to the total discounts and commissions received by the Underwriters under this Agreement. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Issuer and the Guarantor or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or 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 amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Offered Securities purchased by it were resold exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue statement or omission or alleged untrue statement or omission. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective purchase obligations and not joint. The Issuer, the Guarantor and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 6(d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 6(d).

(e)  The remedies provided for in this Section 6 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any indemnified party at law or in equity.

7.  Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Offered Securities hereunder and the aggregate principal amount of Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total principal amount of Offered Securities that the Underwriters are obligated to purchase on the Closing Date, the Representatives may make arrangements satisfactory to the Issuer and the Guarantor for the purchase of such Offered Securities by other persons, including any of the Underwriters, but if no such arrangements are made by the Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to

-16-

their respective commitments hereunder, to purchase the Offered Securities that such defaulting Underwriters agreed but failed to purchase on the Closing Date. If any Underwriter or Underwriters so default and the aggregate principal amount of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total principal amount of Offered Securities that the Underwriters are obligated to purchase on the Closing Date and arrangements satisfactory to the Representatives, the Issuer and the Guarantor for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter, the Issuer, New Parent or the Guarantor, except as provided in Section 8. As used in this Agreement, the term “Underwriter” includes any person substituted for a Underwriter under this Section 7. Nothing herein will relieve a defaulting Underwriter from liability for its default.

8.  Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Issuer, the Guarantor, New Parent or their respective officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Issuer, the Guarantor, New Parent or any of their respective Representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If this Agreement is terminated pursuant to Section 7 or if for any reason the purchase of the Offered Securities by the Underwriters is not consummated, the Issuer and the Guarantor shall remain responsible for the expenses to be paid or reimbursed by them pursuant to Section 3 and the respective obligations of the Issuer and the Guarantor and the Underwriters pursuant to Section 6 shall remain in effect. If the purchase of the Offered Securities by the Underwriters is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 7 or the occurrence of any event specified in clause (iii), (iv), (vi), (vii) or (viii) of Section 5(e), the Issuer and the Guarantor will reimburse the Underwriters for all accountable out-of-pocket expenses (including fees and disbursements of counsel) actually incurred by them in connection with the offering of the Offered Securities. In addition, if any Offered Securities have been purchased hereunder, the representations and warranties in Section 1 and all obligations under Section 3 shall remain in effect.

9.  Notices. All communications hereunder will be in writing and, if sent to the Underwriters will be mailed, hand-delivered, telecopied or transmitted electronically and confirmed to the Underwriters, (i) c/o Goldman Sachs & Co.

Matt Zmigrosky; provided, however, that any notice to a Underwriter pursuant to Section 6 will be mailed, hand-delivered, telecopied or transmitted electronically and confirmed to such Underwriter.

10.  Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors and controlling persons referred to in Section 6, and no other person will have any right or obligation hereunder.

11.  Counterparts.

12.  Representation of Underwriters. The Representatives will act for the several Underwriters in connection with the transactions contemplated by this Agreement, and any action under this Agreement taken by the Representatives will be binding upon all the Underwriters.

13.  Absence of Fiduciary Relationship. Each of the Issuer and the Guarantor acknowledges and agrees that:

(a)  No Other Relationship. The Underwriters have been retained solely to act as underwriters in connection with the sale of the Offered Securities and that no fiduciary, advisory or agency relationship between the Issuer or the Guarantor, on the one hand, and any Underwriter has been created in respect of any of the transactions contemplated by this Agreement or the Final Prospectus, irrespective of whether any Underwriter has advised or are advising the Issuer or the Guarantor on other matters. Any review by the Representatives or any Underwriter of the Issuer, the Guarantor, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Representatives of such Underwriter, as the case may be, and shall not be on behalf of the Issuer, the Guarantor or any other person;

(b)  Arm’s-Length Negotiations. The purchase price of the Offered Securities set forth in this Agreement was established by the Issuer and the Guarantor following discussions and arm’s-length negotiations with the Representatives and the Issuer and the Guarantor are capable of evaluating and understanding and understands and accept the terms, risks and conditions of the transactions contemplated by this Agreement;

-17-

(c)  Absence of Obligation to Disclose. Each of the Issuer and the Guarantor have been advised that each Underwriter and its affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Issuer and the Guarantor and that each Underwriter has no obligation to disclose such interests and transactions to the Issuer and the Guarantor by virtue of any fiduciary, advisory or agency relationship; and

(d)  Waiver. Each of the Issuer, the Guarantor and New Parent to the fullest extent permitted by law, any claims it may have against any Underwriter for breach of fiduciary duty or alleged breach of fiduciary duty and agrees that the Underwriters shall have no liability (whether direct or indirect) to the Issuer, the Guarantor and New Parent in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Issuer, the Guarantor and New Parent, including members, stockholders, employees or creditors of the Issuer, the Guarantor and New Parent.

14.  Applicable 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.

Each of the Issuer, the Guarantor and New Parent hereby submit to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. Each of the Issuer, the Guarantor and New Parent irrevocably and unconditionally waives any objection to the laying of venue of any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby in Federal and state courts in the Borough of Manhattan in The City of New York and irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such suit or proceeding in any such court has been brought in an inconvenient forum.

16.  PATRIOT Act. In accordance with the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Issuer, the Guarantor and New Parent, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

17.  Recognition of the U.S. Special Resolution Regimes.

(a)  In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b)  In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.
