The Notes will be irrevocably and unconditionally guaranteed (the “Guarantees”) by the subsidiaries of the Company listed in Schedule II hereto that have signed this Agreement (each, a “Guarantor” and, collectively, the “Guarantors”), and will be issued pursuant to an Indenture to be dated as of the Closing Date (as defined below) (the “Base Indenture”), as supplemented by a First Supplemental Indenture thereto, also to be dated as of the Closing Date (the “Supplemental Indenture”), among the Company, the Guarantors and The Bank of New York Mellon Trust Company, N.A., as trustee (in such capacity, the “Trustee”). The Base Indenture, as supplemented by the Supplemental Indenture, is hereafter called the “Indenture.”

1. Representations and Warranties of the Company and the Guarantors. The Company and each of the Guarantors jointly and severally represents and warrants to, and agrees with, each of the Underwriters that:

(a) Registration Statement, Pricing Disclosure Package and Prospectus. The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (No. 333-167837) filed on June 28, 2010 (the “Shelf Registration Statement”), for the registration of the Company’s debt and other securities, as

described therein, including the Notes, under the Securities Act, and the offering thereof from time to time in accordance with Rule 415 of the rules and regulations of the Commission (the “Rules and Regulations”) under the Securities Act of 1933, as amended (the “Securities Act”). The Registration Statement is an “automatic shelf registration statement” as defined under Rule 405 of the Securities Act that has been filed with the Commission not earlier than three years prior to the date hereof; and no notice of objection of the Commission to the use of such registration statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Securities Act has been received by the Company. Such registration statement, as so amended, including all information, if any, deemed to be a part thereof pursuant to Rule 430A, 430B or 430C of the Rules and Regulations, is referred to herein as a “Registration Statement.” No stop order suspending the effectiveness of the Registration Statement has been issued and no proceeding for that purpose or pursuant to Section 8A of the Securities Act against the Company or related to the offering and sale of the Notes (the “Offering”) has been initiated or, to the Company’s knowledge, threatened by the Commission. The Company will file the Prospectus (as defined below) with the Commission pursuant to Rule 424(b) of the Rules and Regulations. The base prospectus contained in the Shelf Registration Statement, at the time such registration statement became effective, as supplemented by the final prospectus supplement relating to the Offering, in the form in which it is to be filed with the Commission pursuant to Rule 424(b) of the Rules and Regulations, is hereinafter referred to as the “Prospectus,” except that if any revised prospectus or prospectus supplement shall be provided to the Underwriters by the Company for use in connection with the Offering which differs from the Prospectus (whether or not such revised prospectus or prospectus supplement is required to be filed by the Company pursuant to Rule 424(b) of the Rules and Regulations), the term “Prospectus” shall refer to such revised prospectus or prospectus supplement, as the case may be, from and after the time it is first provided to the Underwriters for such use. Any preliminary prospectus supplement (and the related base prospectus) relating to the Offering filed with the Commission pursuant to Rule 424 of the Rules and Regulations is hereafter referred to as the “Preliminary Prospectus.” Any “issuer free writing prospectus” (as defined in Rule 433 under the Securities Act) relating to the Notes is hereafter referred to as an “Issuer Free Writing Prospectus;” and the Preliminary Prospectus, as amended or supplemented immediately prior to the Applicable Time (as defined below) and as supplemented by the Issuer Free Writing Prospectuses, if any, attached and listed in Annex IV hereto, taken together, are hereafter referred to collectively as the “Pricing Disclosure Package.” Any reference herein to the Registration Statement, the Prospectus or the Pricing Disclosure Package shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3, which were filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), on or before the effective date of the Registration Statement, the date of the Prospectus or the Applicable Time, as the case may be, and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement or the Prospectus shall be deemed to refer to and include (i) the filing of any document under the Exchange Act after the effective date of the Registration Statement or the date of the Prospectus, as the case may be, that is incorporated therein by reference and (ii) any such document so filed. The Company was not an “ineligible issuer” (as defined in Rule 405 under the Securities Act) as of the eligibility determination date for purposes of Rules 164 and 433 under the Securities Act with respect to the offering of the Notes contemplated hereby. All references in this Agreement to the Prospectus, the Registration Statement or any Preliminary Prospectus or Issuer Free Writing Prospectus, or any amendments or supplements to any of the

foregoing, shall be deemed to include any copy thereof filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“▇▇▇▇▇”).

At the applicable effective date of the Registration Statement or any post-effective amendment thereto, as of the date of the Prospectus or any amendment thereto, when any document filed under the Exchange Act is filed and at the Closing Date (as hereinafter defined), the Registration Statement and the Prospectus and any amendments thereof and supplements thereto complied or will comply in all material respects with the applicable provisions of the Securities Act and the Rules and Regulations thereunder and the Exchange Act and the Rules and Regulations thereunder and did not and will not contain an untrue statement of a material fact and (i) in the case of the Registration Statement, did not and will not omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and (ii) in the case of the Prospectus or the Preliminary Prospectus, did not and will not omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. When a related Preliminary Prospectus, if any, was first filed with the Commission (whether filed as part of the Registration Statement or any amendment thereto or pursuant to Rule 424(a) or Rule 429 of the Rules and Regulations) and when any amendment thereof or supplement thereto was first filed with the Commission, such Preliminary Prospectus, if any, and any amendments thereof and supplements thereto complied in all material respects with the applicable provisions of the Securities Act, the Exchange Act and the respective Rules and Regulations thereunder and did not contain an untrue statement of a material fact and did not omit to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

All of the outstanding shares of capital stock of, or other ownership interests in, each of the Company’s subsidiaries have been duly authorized and validly issued and are fully paid and non-assessable; all of such capital stock or other ownership interests (in the case of the Company’s wholly-owned subsidiaries) or all of such capital stock or other ownership interests that the Company owns (in the case of less than wholly-owned subsidiaries as disclosed in the Registration Statement, the Pricing Disclosure Package, the Prospectus or Schedule III hereto) are owned directly or indirectly by the Company,

the Securities Act) to the purchaser, not misleading or, (B) in the case of the Registration Statement, omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or if it shall be necessary at any time to amend or supplement the Pricing Disclosure Package, the Prospectus or the Registration Statement to comply with the Securities Act or the Rules and Regulations, or to file under the Exchange Act so as to comply therewith any document incorporated by reference in the Registration Statement, the Pricing Disclosure Package or the Prospectus or in any amendment thereof or supplement thereto, the Company will notify the Representative promptly and prepare and file with the Commission an appropriate amendment or supplement (in form and substance satisfactory to the Representative) which will correct such statement or omission or which will effect such compliance and will use its best efforts to have any amendment to the Registration Statement declared effective as soon as possible.

agreement will be in addition to any liability which the Company may otherwise have, including but not limited to other liability under this Agreement.

(b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Company, each Guarantor, their respective affiliates, directors and officers who shall have signed the Registration Statement, and each other person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any losses, liabilities, claims, damages and expenses whatsoever as incurred (including, but not limited to, attorneys’ fees and any and all expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in either the Registration Statement, as originally filed or any amendment thereof, or any related Preliminary Prospectus or the Prospectus or the Pricing Disclosure Package, or in any amendment thereof or supplement thereto, or (ii) the omission or alleged omission to state in the (A) Registration Statement, as originally filed or any amendment thereof, a material fact required to be stated therein or necessary to make the statements therein not misleading, or (B) in any Preliminary Prospectus or the Prospectus or the Pricing Disclosure Package, or in any supplement thereto or amendment thereof, a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, in the case of each of (A) and (B), to the extent, but only to the extent, that any such loss, liability, claim, damage or expense arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of such Underwriter through the Representative specifically for use therein, which information is limited to the information set forth in Section 7(d). This indemnity will be in addition to any liability which any Underwriter may otherwise have, including but not limited to other liability under this Agreement.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of any claims or 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 each party against whom indemnification is to be sought in writing of the claim or the commencement thereof (but the failure so to notify an indemnifying party shall not relieve the indemnifying party from any liability which it may have under this Section 7). In case any such claim or action is brought against any indemnified party, and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein, and to the extent it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel satisfactory to such indemnified party. Notwithstanding the foregoing, the indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless (i) the employment of such counsel shall have been authorized in writing by one of the indemnifying parties in connection with the defense of such action, (ii) the indemnifying parties shall not have employed counsel to have charge of the defense of such action within a reasonable

time after notice of commencement of the action, (iii) such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from or additional to those available to one or all of the indemnifying parties (in which case the indemnifying parties shall not have the right to direct the defense of such action on behalf of the indemnified party or parties) or (iv) the named parties in any such proceeding (including any impleading 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 interest between them, in any of which events such fees and expenses shall be borne by the indemnifying parties. No indemnifying party shall, without the prior written consent of the indemnified parties, effect any settlement or compromise of, or consent to the entry of judgment with respect to, any pending or threatened claim, investigation, action or proceeding in respect of which the indemnified party is or reasonably could have been a party and indemnity or contribution may be or could have been sought hereunder by the indemnified party, unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such claim, investigation, action or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or any failure to act, by or on behalf of the indemnified party.

(d) The Underwriters severally confirm and the Company and the Guarantors acknowledge and agree that the statements with respect to the offering of the Notes by the Underwriters set forth in the “Discounts” and “Price stabilization and short positions” paragraphs of the section entitled “Underwriting” in the Pricing Disclosure Package and the Prospectus are correct and constitute the only information concerning such Underwriters furnished in writing to the Company or any Guarantor by or on behalf of the Underwriters specifically for inclusion in the Preliminary Prospectus, the Pricing Disclosure Package and the Prospectus or in any amendment or supplement thereto.

8. Contribution. In order to provide for contribution in circumstances in which the indemnification provided for in Section 7 hereof is for any reason held to be unavailable from any indemnifying party or is insufficient to hold harmless a party indemnified thereunder, the Company, the Guarantors and the Underwriters shall contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by such indemnification provision (including any investigation, legal and other expenses incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claims asserted, but after deducting, in the case of losses, liabilities, claims, damages and expenses suffered by the Company and the Guarantors any contribution received by the Company and the Guarantors from persons, other than the Underwriters, who may also be liable for contribution, including persons who control the Company and the Guarantors within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, officers of the Company who signed the Registration Statement and directors of the Company and the Guarantors) as incurred to which the Company, the Guarantors and one or more of the Underwriters may be subject, in such proportions as is appropriate to reflect the relative benefits received by the Company and the Guarantors on the one hand and the Underwriters on the other hand from the offering of the Notes or, if such allocation is not permitted by applicable law, in such proportions as are appropriate to reflect not only the relative benefits referred to above but also the relative fault of the Company and the Guarantors on the one hand and the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses,

claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantors on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as (x) the total proceeds from the Offering (net of discounts and commissions but before deducting expenses) received by the Company bears to (y) the underwriting discount or commissions received by the Underwriters, in each case as set forth in the Pricing Disclosure Package. The relative fault of each of the Company and the Guarantors on the one hand and of the Underwriters 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 and the Guarantors on the one hand or the Underwriters on the other hand and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Guarantors and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 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 above. Notwithstanding the provisions of this Section 8, (i) no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Notes underwritten by it and distributed to the public were offered to the public exceeds the amount of damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission and (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each Underwriter and its respective affiliates, directors, officers and employees, and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Underwriter, and the Company, each Guarantor, their respective affiliates, directors and officers who shall have signed the Registration Statement, and each other person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company and the Guarantors, subject in each case to clauses (i) and (ii) of this Section 8. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties, notify each party or parties from whom contribution may be sought, but the omission to so notify such party or parties shall not relieve the party or parties from whom contribution may be sought from any obligation it or they may have under this Section 8 or otherwise. The obligations of the Underwriters to contribute pursuant to this Section 8 are several in proportion to the respective principal amount of Notes purchased by each of the Underwriters hereunder and not joint.

With respect to any Indemnified Party who is not a party to this Agreement, the Company, the Guarantors and the Underwriters, as the case may be, shall obtain and hold the rights and benefits of this Section in trust for and on behalf of such Indemnified Party.

9. Default by an Underwriter.

(a) If one or more of the Underwriters shall fail at the Closing Date to purchase the Notes which it or they are obligated to purchase under this Agreement (the

“Defaulted Notes”) and such Defaulted Notes do not exceed in the aggregate 10% of the aggregate principal amount of the Notes, then each non-defaulting Underwriter shall purchase an aggregate amount of the Defaulted Notes equal to the proportion that the aggregate principal amount of Notes to be purchased by such Underwriter as set forth opposite such Underwriter’s name on Schedule I hereto bears to the aggregate principal amount of Notes to be purchased by all non-defaulting Underwriters.

(b) Notwithstanding the foregoing, if the Defaulted Notes equal or exceed in the aggregate 10% of the aggregate principal amount of the Notes, then the non-defaulting Underwriters shall have the right, within 48 hours after the previously scheduled Closing Date, to make arrangements for one or more of such non-defaulting Underwriters to purchase all, but not less than all, of the Defaulted Notes in such amounts as may be agreed upon among such non-defaulting Underwriters and upon the terms herein set forth; provided that if the non-defaulting Underwriters shall not have completed such arrangements within such 48-hour period, then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters or the Company and the Guarantors.

No action taken pursuant to this Section 9 shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement, any of the non-defaulting Underwriters or the Company shall have the right to postpone the Closing Date for a period not exceeding seven days in order to effect any required changes in the Prospectus or in any other documents or arrangements.

10. Survival of Representations and Agreements. All representations and warranties, covenants and agreements of the Underwriters and the Company and the Guarantors contained in this Agreement or in certificates of officers of the Company or any Subsidiary submitted pursuant hereto, including the agreements contained in Section 5, the indemnity agreements contained in Section 7 and the contribution agreements contained in Section 8, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any Underwriter or its respective affiliates, directors, officers and employees, or any person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, or by or on behalf of the Company, any Guarantor, their respective affiliates, directors and officers who shall have signed the Registration Statement, or any other person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and shall survive delivery of and payment for the Notes to and by the Underwriters. The representations contained in Section 1 and the agreements contained in Sections 5, 7, 8 and 11(d) hereof shall survive the termination of this Agreement, including termination pursuant to Section 9 or 11 hereof.

11. Effective Date of Agreement; Termination.

(a) This Agreement shall become effective upon the execution of this Agreement.

(b) The Representative shall have the right to terminate this Agreement, by notice to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) if any domestic or international event or act or occurrence has materially disrupted, or in the opinion of the Representative will in the immediate future materially disrupt, the market for the Company’s securities or securities in general; or (ii) if trading on the New York Stock Exchange (the “NYSE”) or the NASDAQ Global Market (the “NASDAQ”) shall have been suspended or been made subject to material limitations, or minimum or maximum prices for trading shall have been fixed, or maximum ranges for prices for securities shall have been required, on the NYSE or NASDAQ or by order of the Commission or any other governmental authority having jurisdiction; or (iii) if trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; or (iv) if a banking moratorium has been declared by any United States state or federal authority or if any material disruption in commercial banking or securities settlement or clearance services shall have occurred; or (v) if any downgrading shall have occurred in the Company’s corporate credit rating or the rating accorded the Company’s debt securities by any “nationally recognized statistical rating organization” (as defined for purposes of Section 3(a)(62) of the Exchange Act) or if any such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the Company’s debt securities; or (vi) (A) if there shall have occurred any outbreak or escalation of hostilities or acts of terrorism involving the United States or there is a declaration of a national emergency or war by the United States or (B) if there shall have been any other calamity or crisis or any change in political, financial or economic conditions or currency exchange rates or exchange controls if the effect of any such event in (A) or (B) of this sentence, in the sole judgment of the Representative, makes it impracticable or inadvisable to proceed with the offering, sale and delivery of the Notes on the terms and in the manner contemplated by the Pricing Disclosure Package and the Prospectus.

(d) If this Agreement shall be terminated pursuant to any of the provisions hereof (otherwise than pursuant to Section 9(b) or 11(b) hereof), or if the sale of the Notes provided for herein is not consummated because any condition to the obligations of the Underwriters set forth herein is not satisfied or because of any refusal, inability or failure on the part of the Company or any Guarantor to perform any agreement herein or comply with any provision hereof, the Company and the Guarantors, jointly and severally, will, subject to demand by the Representative, reimburse the Underwriters for all reasonable out-of-pocket expenses (including the reasonable fees and expenses of their counsel), incurred by the Underwriters in connection herewith.

The Company is (i) a corporation that, under the laws of the State of Delaware, is duly incorporated, validly existing as a corporation and in good standing and (ii) has the corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Registration Statement, the Pricing Disclosure Package and the Prospectus, to execute, deliver and perform its obligations under the Underwriting Agreement and the Indenture and to consummate the transactions contemplated by the Underwriting Agreement and by the Prospectus.

3. The Company is duly qualified and is in good standing as a foreign corporation authorized to do business in each jurisdiction in which the nature of its business or its ownership or leasing of property requires such qualification, except where the failure to be so qualified would not have a material adverse effect on the Company and its subsidiaries, taken as a whole.

4. The authorized capital stock of the Company consists 400,000,000 shares of common stock, par value $0.01 per share, and 10,000,000 shares of preferred stock, par value $0.01 per share; and all of the issued and outstanding shares of capital stock of, or other ownership interests in, each Delaware Guarantor have been duly and validly authorized and issued and are fully paid and non-assessable, and all of the issued and outstanding shares of capital stock of, or other ownership interests in, each of the Guarantors are, to our knowledge, owned beneficially by the Company or its subsidiaries, free and clear of any perfected security interest or adverse claim, except to the extent described in the Registration Statement, the Pricing Disclosure Package and the Prospectus or as would not be material to the business, prospects, financial conditions or results of operations of the Company and its subsidiaries, taken as a whole.

5. The Indenture and the Guarantees have been duly authorized by all necessary corporate or limited liability company, as the case may be, action of the Company and the Delaware Guarantors and have been duly executed and delivered by the Company and the Delaware Guarantors and are valid and binding agreements of the Company and the Guarantors enforceable against each of them in accordance with their terms.

6. The Notes have been duly authorized, executed and delivered by the Company and, assuming the due authorization and execution of the Guarantees thereof by the Connecticut Guarantors, when the Notes are executed and authenticated in accordance with the provisions of the Indenture and delivered to the Underwriters against payment therefor as provided by the Underwriting Agreement, the Notes and the Guarantees thereof will be entitled to the benefits of

7. The Underwriting Agreement has been duly authorized, executed and delivered by the Company and the Delaware Guarantors.

8. The statements under the “Description of the notes,” and “Material federal income tax considerations” in the Preliminary Prospectus, the Pricing Disclosure Package and the Prospectus, as amended or supplemented through the date hereof, insofar as such statements constitute a summary of legal matters, documents or proceedings referred to therein, fairly present the information so summarized with respect to such legal matters, documents and proceedings, in all material respects.

9. The statements under the captions “Description of our capital stock” in the Preliminary Prospectus, the Pricing Disclosure Package and the Prospectus and “Indemnification of Directors and Officers” in the Registration Statement have been reviewed by us, and, insofar as such statements constitute summaries of certain provisions of the articles of incorporation or bylaws of the Company, statutes, rules, regulations or statements of Law, they constitute fair summaries thereof, in all material respects.

10. To our knowledge, no holder of any securities of the Company has the right to require registration of any security of the Company in connection with the filing of the Registration Statement or the issuance of the Notes.

11. The execution, delivery and performance of the Underwriting Agreement, the Indenture, the Notes and the Guarantees, and the consummation of the transactions contemplated therein, will not (i) violate the provisions of the articles of incorporation or bylaws of the Company or the Delaware Guarantors or (ii) violate any present statute, rule or regulation promulgated by United States federal law or by the State of Delaware and New York that is normally applicable both to general business corporations that are not engaged in regulated business activities and to transactions of the type contemplated by the Registration Statement, the Pricing Disclosure Package, the Prospectus, the Indenture, the Notes and the Underwriting Agreement (collectively, the “Law”).

12. The execution, delivery and performance of the Underwriting Agreement, the Indenture and the Notes, the performance of the Guarantees, and the compliance by the Company and the Guarantors with all the provisions thereof and the consummation of the transactions contemplated thereby do not require any consent, approval, authorization or other order of any court, regulatory body, administrative agency or other governmental body (or pursuant to any consent decree known to us by which the Company or a Guarantor is bound), and do not conflict with or constitute a breach of any of the terms or provisions of, or a default under, the charter or by-laws or comparable organizational documents of the Company or any of the Delaware Guarantors or any agreement filed as an exhibit to the Registration Statement, the Company’s Annual Report on Form 10-K for the year ended December 31, 2010, including any amendments thereto (the “Annual Report”), or the Company’s Quarterly Reports on Form 10-Q for the quarters ended March 31, 2011 and June 30, 2011 (the “Quarterly Reports”) or violate or

The Registration Statement is an “automatic shelf registration statement” as defined under Rule 405 of the Securities Act that has been filed with the Commission not earlier than three years prior to the date of the Underwriting Agreement.
