(gg)    None of the Company, the Guarantors or any affiliate (as defined in Rule 501(b) of Regulation D under the Securities Act, an “Affiliate”) of the Company or the Guarantors has directly, or through any agent (excluding the Initial Purchasers, their affiliates, officers, directors, employees, agents and representatives), (i) sold, offered for sale, solicited offers to buy or otherwise negotiated in respect of, any security (as defined in the Securities Act) which is or will be integrated with the sale of the Securities in a manner that would require the registration under the Securities Act of the Securities or (ii) offered, solicited offers to buy or sold the Securities by any form of general solicitation or general advertising (as those terms are used in Regulation D under the Securities Act) or in any manner involving a public offering within the meaning of Section 4(a)(2) of the Securities Act.

(hh)    None of the Company, the Guarantors, their Affiliates or any person acting on its or their behalf has (i) taken, directly or indirectly, any action designed to, or that might reasonably be expected to, cause or result in stabilization or manipulation of the price of any security of the Company or any Guarantor to facilitate the sale or resale of the Securities, (ii) sold, bid for, purchased or paid any person any compensation for soliciting purchases of the Securities in a manner that would require registration of the Securities under the Securities Act or paid or agreed to pay to any person any compensation for soliciting another to purchase any other securities of the Company or any Guarantor in a manner that would require registration of the Securities under the Securities Act or (iii) engaged in any “directed selling effort” (as defined by Regulation S) with respect to the Securities. The Company, the Guarantors and their Affiliates and any person acting on its or their behalf have complied and will comply with the offering restrictions requirement of Regulation S, except no representation, warranty or agreement is made by the Company or the Guarantors in this paragraph with respect to the Initial Purchasers.

(ii)    Assuming the accuracy of the Initial Purchasers’ representations in Section 8 hereof and their compliance with the agreements set forth therein, it is not necessary in connection with the offer, sale and delivery of the Securities to the Initial Purchasers and the reoffer, sale and delivery to subsequent purchasers in the manner contemplated by this Agreement to register the Securities under the Securities Act or to qualify the Indenture under the Trust Indenture Act.

(jj)    The Securities satisfy the requirements set forth in Rule 144A(d)(3) under the Securities Act.

(kk)    The agreements or instruments listed on Schedule III hereto constitute all of the agreements material to the Company.

(ll)    Except as described in the section entitled “Private Placement” in the Time of Sale Memorandum and the Final Memorandum, there are no contracts, agreements or understandings between the Company or any subsidiary and any other person other than the Initial Purchasers pursuant to this Agreement that would give rise to a valid claim against the Company, any subsidiary or any of the Initial Purchasers for a brokerage commission, finder’s fee or like payment in connection with the issuance, purchase and sale of the Securities.

(mm)    The statistical and market-related data included in the Time of Sale Memorandum and the Final Memorandum are based on or derived from sources that the Company and its subsidiaries generally believe to be reliable and forward looking statements included in the Time of Sale Memorandum and the Final Memorandum are based on management’s good faith estimates.

Each certificate signed by any officer of the Company or any Guarantor and delivered to the Initial Purchasers or counsel for the Initial Purchasers pursuant to, or in connection with, this Agreement shall be deemed to be a representation and warranty by the Company or any Guarantor to the Initial Purchasers as to the matters covered by such certificate.

The Company acknowledges that the Initial Purchasers and, for purposes of the opinions to be delivered to the Initial Purchasers pursuant to Section 5 of this Agreement, counsel to the Company and counsel to the Initial Purchasers will rely upon the accuracy and truth of the foregoing representations and the Company hereby consents to such reliance.

2.    Agreements to Sell and Purchase. The Company hereby agrees to sell to the several Initial Purchasers, and each Initial Purchaser, upon the basis of the representations and warranties herein contained, but subject to the conditions hereinafter stated, agrees, severally and not jointly, to purchase from the Company the respective principal amount of Notes set forth in Schedule I hereto opposite its name at a purchase price of 98.00% of the principal amount thereof (the “Purchase Price”).

3.    Terms of Offering.

The Securities shall be delivered to you on the Closing Date for the respective accounts of the several Initial Purchasers, with any transfer taxes payable in connection with the transfer of the Securities to the Initial Purchasers duly paid, against payment of the Purchase Price therefor.

(i)    there shall not have occurred any change, or any development involving a prospective change, in the condition, financial or otherwise, or in the earnings, business or operations of the Company and its subsidiaries, taken as a whole, from that set forth in the Time of Sale Memorandum (exclusive of any amendment or supplement) provided to prospective purchasers of the Securities that, in your judgment, is material and adverse and that makes it, in your judgment, impracticable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated in the Time of Sale Memorandum (exclusive of any amendment or supplement).

(b)    The Initial Purchasers shall have received on the Closing Date a certificate from the Company dated the Closing Date and signed by executive officers of the Company to the effect set forth in Section 5(a)(i) and to the effect that the representations and warranties of the Company contained in this Agreement are true and correct as of the date hereof and the Closing Date and that the Company has complied with all of the agreements and satisfied all of the conditions on its part to be performed or satisfied hereunder on or before the Closing Date.

The officer signing and delivering such certificates may rely upon the best of his or her knowledge as to proceedings threatened.

(c)    The Initial Purchasers shall have received on the Closing Date a certificate dated the Closing Date and signed by executive officers of each Guarantor, to the effect that the representations and warranties of each such Guarantor contained in this Agreement are true and correct as of the Closing Date and that each such Guarantor has complied with all of the agreements and satisfied all of the conditions on its part to be performed or satisfied hereunder on or before the Closing Date.

Each such officer signing and delivering such certificate may rely upon the best of his or her knowledge as to proceedings threatened.

(e)    The Initial Purchasers shall have received an opinion, dated the Closing Date, of Cahill Gordon & Reindel LLP, counsel for the Initial Purchasers, with respect to the issuance and sale of the Securities and such other related matters as the Initial Purchasers may reasonably require, and the Company and the Guarantors shall have furnished to such counsel such documents as it may reasonably request for the purpose of enabling it to pass upon such matters.

(f)    The Initial Purchasers shall have received on each of the date hereof and the Closing Date a letter, dated the date hereof or the Closing Date, as the case may be, in form and substance satisfactory to counsel for the Initial Purchasers, from BKD, LLP, independent registered public accountants, containing statements and information of the type ordinarily included in accountants’ “comfort letters” to underwriters with respect to the financial statements and certain financial information contained in the Time of Sale Memorandum and the Final Memorandum; provided that the letter delivered on the Closing Date by BKD, LLP shall use a “cut-off date” within three days of the date of such letter.

6.    Covenants of the Company and the Guarantors. In further consideration of the agreements of the Initial Purchasers contained in this Agreement, the Company and each Guarantor, jointly and severally, covenants with each Initial Purchaser as follows:

(a)    To furnish to you in New York City, without charge, prior to 9:00 a.m. New York City time on the business day (defined as any day other than a Saturday, a Sunday or a legal holiday or a day on which banking institutions or trust companies are authorized or obligated by law to close in New York City) next succeeding the date of this Agreement and during the period mentioned in Section 6(c) and 6(d), as many copies of the Time of Sale Memorandum, the Preliminary Memorandum and the Final Memorandum and any supplements and amendments thereto as you may reasonably request.

(b)    Before amending or supplementing the Time of Sale Memorandum or the Final Memorandum or at any time prior to the date on which all of the Securities shall have been sold by the Initial Purchasers, to furnish to you a copy of each such proposed amendment or

supplement and not to use any such proposed amendment or supplement to which you reasonably object.

(c)    If the Time of Sale Memorandum is being used to solicit offers to buy the Securities at a time when the Final Memorandum is not yet available to prospective purchasers and any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Time of Sale Memorandum in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if, in the opinion of counsel for the Initial Purchasers or the Company, it is necessary to amend or supplement the Time of Sale Memorandum to comply with applicable securities law, forthwith to prepare and furnish, subject to Section 6(b) hereof, at its own expense, to the Initial Purchasers, either amendments or supplements to the Time of Sale Memorandum so that the statements in the Time of Sale Memorandum as so amended or supplemented will not, in the light of the circumstances when the Time of Sale Memorandum is delivered to a purchaser, be misleading or so that the Time of Sale Memorandum, as amended or supplemented, will comply with applicable securities law.

(d)    If, during such period after the date hereof and prior to the date on which all of the Securities shall have been sold by the Initial Purchasers, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Final Memorandum in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if, in the opinion of counsel for the Initial Purchasers or the Company, it is necessary to amend or supplement the Final Memorandum to comply with applicable securities laws, forthwith to prepare and furnish, subject to Section 6(b) hereof, at its own expense, to the Initial Purchasers, either amendments or supplements to the Final Memorandum so that the statements in the Final Memorandum as so amended or supplemented will not, in the light of the circumstances when the Final Memorandum is delivered to a purchaser, be misleading or so that the Final Memorandum, as amended or supplemented, will comply with applicable securities laws.

(e)    To endeavor to qualify the Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions as you shall reasonably request; provided, however, that in connection therewith neither the Company nor any subsidiary shall be required to qualify as a foreign corporation or other legal entity, as the case may be, or as a dealer in the securities in any jurisdiction where it would not otherwise be required to so qualify but for this paragraph (d) or to file a general consent to service of process in any jurisdiction where it is not so qualified or so subject or to subject itself to taxation in any jurisdiction if it is not otherwise so subject.

(f)    Whether or not the transactions contemplated in this Agreement are consummated or this Agreement is terminated, to pay or cause to be paid all expenses incident to the performance of its obligations under this Agreement, including: (i) the fees, disbursements and expenses of the Company’s and the Guarantors’ counsel and the Company’s and the Guarantors’ accountants in connection with the issuance and sale of the Securities and all other fees or expenses in connection with the preparation of the Time of Sale Memorandum, the Preliminary Memorandum and the Final Memorandum, and all amendments and supplements thereto, including all printing costs associated therewith, and the delivering of copies thereof to the Initial Purchasers, in the quantities herein above specified, (ii) all costs and expenses related to the transfer and delivery of the Securities to the Initial Purchasers, including any transfer or other taxes payable thereon, (iii) the cost of printing or producing any Blue Sky or legal investment memorandum in connection with the offer and sale of the Securities under state

securities laws and all expenses in connection with the qualification of the Securities for offer and sale under state securities laws as provided in Section 6(e) hereof, including filing fees and the reasonable fees and disbursements of counsel for the Initial Purchasers in connection with such qualification and in connection with the Blue Sky or legal investment memorandum, (iv) any fees charged by rating agencies for the rating of the Securities, (v) the fees and expenses of the Company incurred in connection with the approval of the inclusion of the Securities in the book-entry system of The Depository Trust Company, (vi) the costs and charges of the Trustee and any transfer agent, registrar or depositary, (vii) the issuance, transfer and delivery of the Securities by the Company to the Initial Purchasers, (viii) the costs and expenses of the Company and the Guarantors relating to investor presentations on any “road show” undertaken in connection with the marketing of the offering of the Securities, including, without limitation, expenses associated with the production of road show slides and graphics, fees and expenses of any consultants engaged in connection with the road show presentations with the prior approval of the Company, travel and lodging expenses of the representatives and officers of the Company and the Guarantors and any such consultants, and the cost of any aircraft chartered in connection with the road show and (ix) all other costs and expenses incident to the performance of the obligations of the Company and the Guarantors hereunder for which provision is not otherwise made in this Section. It is understood, however, that except as provided in this Section 6, Section 9, and the last paragraph of Section 11, the Initial Purchasers will pay all of their costs and expenses, including fees-and disbursements of their counsel, transfer taxes payable on resale of any of the Securities by them and any advertising expenses connected with any offers they may make.

(g)    That none of the Company, the Guarantors nor any of their Affiliates will sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in the Securities Act) which could be integrated with the sale of the Securities in a manner which would require the registration of the Securities under the Securities Act.

(h)    That none of the Company, the Guarantors nor any of their Affiliates, will solicit any offer to buy or offer or sell the Securities by means of any form of general solicitation or general advertising (as those terms are used in Regulation D under the Securities Act) or in any manner involving a public offering within the meaning of Section 4(a)(2) of the Securities Act.

(i)    While any of the Securities remain “restricted securities” within the meaning of the Securities Act, the Company will make available, upon request, to any seller of such Securities the information specified in Rule 144A(d)(4) under the Securities Act, unless the Company is then subject to Section 13 or 15(d) of the Securities Exchange Act.

(j)    That none of the Company, the Guarantors nor any of their Affiliates nor any person acting on its or their behalf (other than the Initial Purchasers) will engage in any directed selling efforts (as that terms defined in Regulation S) with respect to the Securities, and each of the Company, the Guarantors and their Affiliates and each person acting on its or their behalf (other than the Initial Purchasers) will comply with the offering restrictions requirement of Regulation S.

(k)    [Reserved].

(l)    That none of the Company or the Guarantors will use any written communication which would be considered an issuer free writing prospectus (as defined in Rule 433 of the Securities Act) if this were a registered offering, without the consent of the Initial Purchasers.

(m)    Neither the Company nor any of the Guarantors will take, directly or indirectly, any action designed to or that could reasonably be expected to cause or result in any stabilization or manipulation of the price of the Securities.

(n)    Not to, and not to permit any of its Affiliates or anyone acting on its or its Affiliates’ behalf to (other than the Initial Purchasers and their Affiliates), distribute prior to the Closing Date any offering material in connection with the offer and sale of the Securities other than the Time of Sale Memorandum and the Final Memorandum.

(o)    During the period beginning on the date hereof and continuing to the date that is 90 days after the Closing Date, without the prior written consent of Deutsche Bank Securities Inc., the Company will not offer, sell, contract to sell or otherwise dispose of, except as provided hereunder, any debt securities of the Company (or guaranteed by the Company) that are similar to the Notes; provided that in the event this Agreement is terminated after the execution and delivery of this Agreement and prior to the Closing Date, this clause (o) shall not survive.

7.    Certain Agreements of the Initial Purchasers. Each Initial Purchaser hereby, severally and not jointly, represents and agrees that it has not and will not use, authorize use of, refer to, or participate in the planning for use of, any written communication that constitutes an offer to sell or the solicitation of an offer to buy the Securities other than (i) the Preliminary Memorandum and the Final Memorandum, (ii) a written communication that contains no “issuer information” (as defined in Rule 433(h)(2) under the Securities Act) that was not included (including through incorporation by reference) in the Preliminary Memorandum or the Final Memorandum, (iii) any written communication listed on Schedule V or prepared pursuant to Section 6(n) above (including any electronic road show), (iv) any written communication prepared by such Initial Purchaser and approved by the Company in advance in writing or (v) any written communication that contains the possible terms or the terms of the Securities and/or other information that was included (including through incorporation by reference) in the Time of Sale Memorandum or the Final Memorandum.

8.    Offering of Securities; Restrictions on Transfer.

(a)    Each Initial Purchaser, severally and not jointly, represents and warrants that such Initial Purchaser is a qualified institutional buyer as defined in Rule 144A under the Securities Act (a “QIB”). Each Initial Purchaser, severally and not jointly, agrees with the Company that (i) it will not solicit offers for, or offer or sell, such Securities by any form of general solicitation or general advertising (as those terms are used in Regulation D under the Securities Act) or in any manner involving a public offering within the meaning of Section 4(a)(2) of the Securities Act and (ii) it will solicit offers for such Securities only from, and will offer such Securities only to, persons that it reasonably believes to be (A) in the case of offers inside the United States, QIBs and (B) in the case of offers outside the United States, to persons other than U.S. persons (“foreign purchasers,” which term shall include dealers or other professional fiduciaries in the United States acting on a discretionary basis for foreign beneficial owners (other than an estate or trust)) in reliance upon Regulation S under the Securities Act.

(b)    Each Initial Purchaser, severally and not jointly, represents, warrants, and agrees with respect to offers and sales outside the United States that:

(i)    such Initial Purchaser understands that no action has been or will be taken in any jurisdiction by the Company or the Guarantors that would permit a public offering of the Securities, or possession or distribution of the Time of Sale Memorandum or either Memorandum

or any other offering or publicity material relating to the Securities, in any country or jurisdiction where action for that purpose is required;

(ii)    the Securities have not been registered under the Securities Act and may not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons except in accordance with Rule 144A or Regulation S under the Securities Act or pursuant to another exemption from the registration requirements of the Securities Act;

(iii)    such Initial Purchaser has offered the Securities and will offer and sell the Securities (A) as part of their distribution at any time and (B) otherwise until 40 days after the later of the commencement of the offering and the Closing Date, only in accordance with Rule 903 of Regulation S or as otherwise permitted in Section 8(a); accordingly, neither such Initial Purchaser, its Affiliates nor any persons acting on its or their behalf have engaged or will engage in any directed selling efforts (within the meaning of Regulation S) with respect to the Securities, and any such Initial Purchaser, its Affiliates and any such persons have complied and will comply with the offering restrictions requirement of Regulation S;

(iv)    such Initial Purchaser, in relation to each Member State of the European Economic Area which has implemented the Prospectus Directive (each, a “Member State”), represents, warrants and agrees that with effect from and including the date on which the Prospectus Directive is implemented in that Member State it has not made and will not make an offer of Securities to the public in that Member State, except that it may, with effect from and including such date, make an offer of Securities to the public in that Member State:

(a)    to any legal entity which is a qualified investor as defined in the Prospectus Directive;

(b)     to fewer than 100 or, if the Relevant Member State has implemented the relevant provision of the 2010 PD Amending Directive, 150, natural or legal persons (other than qualified investors as defined in the Prospectus Directive), as permitted under the Prospectus Directive, subject to obtaining the prior consent of the relevant dealer or dealers nominated by the Issuer for any such offer; or

(c)    in any other circumstances falling within Article 3(2) of the Prospectus Directive,

provided that no such offer of Notes shall require the Company or any Initial Purchaser to publish a prospectus pursuant to Article 3 of the Prospectus Directive;

For the purposes of the above, the expression an “offer of Securities to the public” in relation to any Securities in any Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the Securities to be offered so as to enable an investor to decide to purchase or subscribe for the Securities, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State and the expression “Prospectus Directive” means Directive 2003/71/EC (and amendments thereto, including the 2010 PD Amending Directive, to the extent implemented in the Relevant Member State), and includes any relevant implementing measure in the Relevant Member State, and the expression “2010 PD Amending Directive” means Directive 2010/73/EU;

(v)    such Initial Purchaser (A) has complied and will comply with all applicable provisions of the Financial Services and Markets Act 2000 (the “FSMA”) with respect to

anything done by it in relation to the Securities in, from or otherwise involving the United Kingdom, and (B) will only communicate or cause to be communicated any invitation or inducement to engage in investment activity (within the meaning of section 21 of the FSMA) received by it in connection with the issue or sale of the Securities in circumstances in which section 21(1) of the FSMA does not apply to the Company and the Guarantors; and

(vi)    such Initial Purchaser agrees that, at or prior to confirmation of sales of the Securities, it will have sent to each distributor, dealer or person receiving a selling concession, fee or other remuneration that purchases Securities from it during the distribution compliance period a confirmation or notice to substantially the following effect:

“The Securities covered hereby have not been registered under the U.S. Securities Act of 1933 (the “Securities Act”) and may not be offered and sold within the United States or to, or for the account or benefit of, U.S. persons (i) as part of their distribution at any time or (ii) otherwise until 40 days after the later of the commencement of the offering and the closing date, except in either case in accordance with Regulation S (or Rule 144A if available) under the Securities Act. Terms used above have the meaning given to them by Regulation S.”

Terms used in this Section 8(b) have the meanings given to them by Regulation S, unless otherwise indicated.

(c)    Each Initial Purchaser, severally and not jointly, agrees and understands that the Company and, for purposes of the opinions to be delivered to the Initial Purchasers pursuant to Section 5(c) hereof, counsel to the Company and the Guarantors, respectively, may rely on the accuracy and truth of the foregoing representations, warranties and covenants in this Section 8 and the Initial Purchasers and the Company hereby consent to such reliance.

9.    Indemnity and Contribution.

(a)    The Company and each Guarantor, jointly and severally, agrees to indemnify and hold harmless each Initial Purchaser, each person, if any, who controls any Initial Purchaser within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of any Initial Purchaser within the meaning of Rule 405 under the Securities Act and which participated in the offering from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim upon presentation of a statement of statements therefor in reasonable detail) caused by any untrue statement or alleged untrue statement of a material fact contained in the Time of Sale Memorandum, any Issuer Written Communication, or the Final Memorandum (as amended or supplemented if the Company or any Guarantor shall have furnished any amendments or supplements thereto), or caused by any omission or alleged omission to state therein a material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Initial Purchaser furnished to the Company in writing by such Initial Purchaser through you expressly for use therein, it being understood and agreed that the only such information furnished by or on behalf of any Initial Purchaser consists of the information described as such in Section 13 hereof.

(b)    Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company, the directors and officers of the Company, each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each Guarantor, their directors and their officers to the same extent as the foregoing indemnity from the Company and the Guarantors to such Initial Purchaser, but only with reference to information relating to such Initial Purchaser furnished to the Company in writing by such Initial Purchaser through you expressly for use in the Time of Sale Memorandum, any Issuer Written Communication, or the Final Memorandum or any amendments or supplements thereto, it being understood and agreed that the only such information furnished by or on behalf of any Initial Purchaser consists of the information described as such in Section 13 hereof.

(c)    In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 9(a) or 9(b), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. 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 retention of such counsel or (ii) the named parties to 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 that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings 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 such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by Deutsche Bank Securities Inc., in the case of parties indemnified pursuant to Section 9(a), and by the Company, in the case of parties indemnified pursuant to Section 9(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought thereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and does not include any findings of fault, culpability or failure to act by or on behalf of any indemnified party.

(d)    To the extent the indemnification provided for in Section 9(a) or 9(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, 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 (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors on the one hand and the Initial Purchasers on the other hand from the offering of the Securities or (ii) if the allocation provided by clause 9(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 9(d)(i) above but also the relative fault of the Company and the Guarantors on the one hand and

of the Initial Purchasers on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantors on the one hand and the Initial Purchasers on the other hand in connection with the offering of the Securities shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Securities (before deducting expenses) received by the Company and the Guarantors and the total discounts and commissions received by the Initial Purchasers, in each case as set forth in the Time of Sale Memorandum and the Final Memorandum, bear to the aggregate offering price of the Securities. The relative fault of the Company and the Guarantors on the one hand, and of the Initial Purchasers on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Guarantors or by the Initial Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Initial Purchasers’ respective obligations to contribute pursuant to this Section 9 are several in proportion to the respective principal amount of Securities they have purchased hereunder, and not joint.

(e)    The Company, each Guarantor and the Initial Purchasers agree that it would not be just or equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Initial Purchasers 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 Section 9(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 9(d) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 9, no Initial Purchaser shall be required to contribute any amount in excess of the amount by which the total discounts, commissions and other compensation received by such Initial Purchaser under this Agreement exceeds the amount of any damages that such Initial Purchaser 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 remedies provided for in this Section 9 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.

(f)    The indemnity and contribution provisions contained in this Section 9 and the representations, warranties and other statements of the Company, the Guarantors and the Initial Purchasers contained in this Agreement 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 any Initial Purchaser, any person controlling any Initial Purchaser or any affiliate of any Initial Purchaser or by or on behalf of the Company and the Guarantors, their officers or directors or any person controlling the Company or the Guarantors and (iii) acceptance of and payment for any of the Securities.

10.    Termination. The Initial Purchasers may terminate this Agreement by notice given by you to the Company if, after the execution and delivery of this Agreement and prior to the Closing Date, (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange, the NYSE MKT LLC or the NASDAQ Global Market, (ii) trading of any securities of any of the Company or the Guarantors shall have been suspended on any exchange or in any over-the-counter market in which such securities trade, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or (v)

there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in your judgment, is material and adverse and which, individually or together with any other event specified in this clause (v), makes it, in your judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Securities on the terms and in the manner contemplated in the Time of Sale Memorandum and the Final Memorandum.

11.    Effectiveness, Defaulting Initial Purchasers. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date, any one or more of the Initial Purchasers shall fail or refuse to purchase Securities that it or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase is not more than one-tenth of the aggregate principal amount of Securities to be purchased on such date, the other non-defaulting Initial Purchasers shall be obligated severally in the proportions that the principal amount of Securities set forth opposite their respective names in Schedule I bears to the aggregate principal amount of Securities set forth opposite the names of all such non-defaulting Initial Purchasers, or in such other proportions as you may specify, to purchase the Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase on such date; provided that in no event shall the principal amount of Securities that any Initial Purchaser has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 11 by an amount in excess of one-ninth of such principal amount of Securities without the written consent of such Initial Purchaser. If, on the Closing Date any Initial Purchaser or Initial Purchasers shall fail or refuse to purchase Securities which it or they have agreed to purchase hereunder on such date and the aggregate principal amount of Securities with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Securities to be purchased on such date, and arrangements satisfactory to you and the Company for the purchase of such Securities are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Initial Purchaser or of the Company. In any such case either you or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Time of Sale Memorandum, the Preliminary Memorandum or in the Final Memorandum or in any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Initial Purchaser from liability in respect of any default of such Initial Purchaser under this Agreement.

If this Agreement shall be terminated by the Initial Purchasers, or any of them, because of any failure or refusal on the part of the Company or the Guarantors to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company or the Guarantors shall be unable to perform their respective obligations under this Agreement, the Company and the Guarantors will reimburse the Initial Purchasers or such Initial Purchaser as have so terminated this Agreement, other than by reason of a default by the Initial Purchasers, with respect to themselves, severally, for all reasonable out-of-pocket expenses (including the reasonable fees and disbursements of their counsel) incurred by such Initial Purchaser in connection with this Agreement or the offering contemplated hereunder.

12.    Entire Agreement.

(a)    This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Securities, represents the entire agreement between the Company and the Initial Purchasers with respect

to the preparation of the Time of Sale Memorandum or the Final Memorandum, the conduct of the offering, and the purchase and sale of the Securities.

(b)    The Company and the Guarantors acknowledge and agree that each Initial Purchaser is acting solely in the capacity of an arm’s length contractual counterparty to the Company and the Guarantors with respect to the offering of Securities contemplated hereby (including in connection with determining the terms of the Offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company, the Guarantors or any other person. Additionally, neither Deutsche Bank Securities Inc. nor any other Initial Purchaser is advising the Company, the Guarantors or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Company and the Guarantors shall consult with their own advisors concerning such matters and shall be responsible for making their own independent investigation and appraisal of the transactions contemplated hereby, and neither Deutsche Bank Securities Inc. nor any other Initial Purchaser shall have any responsibility or liability to the Company or the Guarantors with respect thereto. Any review by Deutsche Bank Securities Inc. or any Initial Purchaser of the Company, the Guarantors, and the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of Deutsche Bank Securities Inc. or such Initial Purchaser, as the case may be, and shall not be on behalf of the Company, the Guarantors or any other persons.

13.    Information Supplied by the Initial Purchasers. The statements set forth in the third sentence of the third paragraph and the second and third sentence of the ninth paragraph and the second, third and fourth sentence of the tenth paragraph under the heading “Private Placement” in the Time of Sale Memorandum and the Final Memorandum (to the extent such statements relate to the Initial Purchasers) constitute the “Initial Purchaser Information.”
