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Exchange Offer is being made pursuant to this Agreement and that all Registrable Securities validly tendered and not withdrawn will be accepted for exchange;

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

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

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

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

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

(i)             accept for exchange Registrable Securities or portions thereof tendered and not validly withdrawn pursuant to the Exchange Offer; and

(ii)            deliver, or cause to be delivered, to the Trustee for cancellation all Registrable Securities or portions thereof so accepted for exchange by the Company and issue, and cause the Trustee to promptly authenticate and mail to each Holder, an

Exchange Security of the applicable series equal in principal amount to the principal amount of the Registrable Securities surrendered by such Holder.

The Company and the Guarantors shall use their reasonable best efforts to complete the Exchange Offer as provided above and shall comply with the applicable requirements of the 1933 Act, the 1934 Act and other applicable laws and regulations in connection with the Exchange Offer.  The Exchange Offer shall not be subject to any conditions, other than that the Exchange Offer does not violate applicable law or any applicable interpretation of the Staff of the SEC.  The Company shall inform the Initial Purchasers of the names and addresses of the Holders to whom the Exchange Offer is made, and the Initial Purchasers shall have the right, subject to applicable law, to contact such Holders and otherwise facilitate the tender of Registrable Securities in the Exchange Offer.

If the Company and the Guarantors effect the Exchange Offer, the Company and the Guarantors shall be entitled to close the Exchange Offer twenty (20) business days after such commencement (provided that the Company and the Guarantors have accepted all the Securities theretofore validly tendered and not withdrawn in accordance with the terms of the Exchange Offer).

Each Holder participating in the Exchange Offer shall be required to represent to the Company and the Guarantors in writing that at the time of the consummation of the Exchange Offer (i) any Exchange Securities received by such Holder will be acquired in the ordinary course of business, (ii) such Holder will have no arrangements or understanding with any Person to participate in the distribution (within the meaning of the 1933 Act) of the Exchange Securities and (iii) such Holder is not affiliate of either the Company or any of the Guarantors within the meaning of Rule 405 under the 1933 Act, (iv) if such Holder is not a broker dealer, that it is not engaged in and does not intend to engage in, the distribution of the Exchange Securities and (v) if such Holder is a broker dealer, that it will receive Exchange Securities for its own account in exchange for Securities that were acquired as a result of market making activities or other trading activities and that it will be required to acknowledge that it will deliver a prospectus in connection with the resale of such Exchange Securities.

(b)            In the event that (i) the Company and the Guarantors determine that the Exchange Offer Registration provided for in Section 2(a) above is not available or may not be consummated as soon as practicable after the last Exchange Date because it would violate applicable law or the applicable interpretations of the Staff of the SEC, (ii) the Exchange Offer is not for any other reason consummated by September 9, 2015 or (iii) the Exchange Offer has been completed and in the opinion of counsel for the Initial Purchasers a Registration Statement must be filed and a Prospectus must be delivered by the Initial Purchasers in connection with any offering or sale of Registrable Securities, the Company and the Guarantors shall use their reasonable best efforts to cause to be filed as soon as practicable after such determination, date or notice of such opinion of counsel is given to the Company, as the case may be, a Shelf Registration Statement providing for the sale by the Holders of all of the Registrable Securities and to have such Shelf Registration Statement declared effective by the SEC.  In the event the Company and the Guarantors are required to file a Shelf Registration Statement solely as a result of the matters referred to in clause (iii) of the preceding sentence, the Company and the

Guarantors shall use their reasonable best efforts to file and have declared effective by the SEC both an Exchange Offer Registration Statement pursuant to Section 2(a) with respect to all Registrable Securities and a Shelf Registration Statement (which may be a combined Registration Statement with the Exchange Offer Registration Statement) with respect to offers and sales of Registrable Securities held by the Initial Purchasers after completion of the Exchange Offer.  The Company and the Guarantors agree to use their reasonable best efforts to keep the Shelf Registration Statement continuously effective until the second anniversary of the Closing Date or such shorter period that will terminate when all of the Registrable Securities covered by the Shelf Registration Statement have been sold pursuant to the Shelf Registration Statement. The Company and the Guarantors further agree to supplement or amend the Shelf Registration Statement if required by the rules, regulations or instructions applicable to the registration form used by the Company and the Guarantors for such Shelf Registration Statement or by the 1933 Act or by any other rules and regulations thereunder for shelf registration or if reasonably requested by a Holder with respect to information relating to such Holder, and to use its reasonable best efforts to cause any such amendment to become effective and such Shelf Registration Statement to become usable as soon as thereafter practicable.  The Company and the Guarantors agree to furnish to the Holders of Registrable Securities copies of any such supplement or amendment promptly after its being used or filed with the SEC.  To the extent that the Company and the Guarantors are required to include any Registrable Securities in a Shelf Registration Statement, the Company and the Guarantors may include such Registrable Securities on any other shelf registration statement otherwise filed by the Company with respect to any of its other securities.

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

(d)            An Exchange Offer Registration Statement pursuant to Section 2(a) hereof or a Shelf Registration Statement pursuant to Section 2(b) hereof will not be deemed to have become effective unless it has been declared effective by the SEC; provided , however , that, if, after it has been declared effective, the offering of Registrable Securities of any series pursuant to a Shelf Registration Statement is interfered with by any stop order, injunction or other order or requirement of the SEC or any other governmental agency or court, such Registration Statement with respect to such series of Registrable Securities will be deemed not to have become effective during the period of such interference until the offering of Registrable Securities of such series pursuant to such Registration Statement may legally resume.  In the event the Exchange Offer with respect to a series of Registrable Securities is not consummated and the Shelf Registration Statement with respect to such series is not declared effective on or prior to September 9, 2015 (and in the case of a Shelf Registration Statement with respect to such series , thereafter ceases to be effective as provided in the preceding sentence) , the interest rate on such series of Securities will be increased by 0.5% per annum until the Exchange Offer with respect to such series is consummated or the Shelf Registration Statement with respect to such series is declared effective by the SEC.

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

In the case of a Shelf Registration Statement, the Company and the Guarantors may require each Holder of Registrable Securities to furnish to the Company and the Guarantors such information regarding the Holder and the proposed distribution by such Holder of such Registrable Securities as the Company and the Guarantors may from time to time reasonably request in writing.

In the case of a Shelf Registration Statement, each Holder agrees that, upon receipt of any notice from the Company and the Guarantors of the happening of any event of the kind described in Section 3(e)(v) hereof, such Holder will forthwith discontinue disposition of Registrable Securities pursuant to a Registration Statement until such Holder’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 3(i) hereof, and, if so directed by the Company and the Guarantors, such Holder will deliver to the Company and the Guarantors (at its expense) all copies in its possession, other than permanent file copies then in such Holder’s possession, of the Prospectus covering such Registrable Securities current at the time of receipt of such notice.  If the Company and the Guarantors shall give any such notice to suspend the disposition of Registrable Securities pursuant to a Registration Statement, the Company and the Guarantors shall extend the period during which the Registration Statement shall be maintained effective pursuant to this Agreement by the number of days during the period from and including the date of the giving of such notice to and including the date when the Holders shall have received copies of the supplemented or amended Prospectus necessary to resume such dispositions.  The Company and the Guarantors may give any such notice only twice during any 365-day period and any such suspensions may not exceed 30 days for each suspension and there may not be more than two suspensions in effect during any 365-day period.

4.              Participation of Broker-Dealers in Exchange Offer .

(a)            The Staff of the SEC has taken the position that any broker-dealer that receives Exchange Securities for its own account in the Exchange Offer in exchange for Securities that were acquired by such broker-dealer as a result of market-making or other trading activities (a “ Participating Broker-Dealer ”), may be deemed to be an “underwriter” within the meaning of the 1933 Act and must deliver a prospectus meeting the requirements of the 1933 Act in connection with any resale of such Exchange Securities.

The Company and the Guarantors understand that it is the Staff’s position that if the Prospectus contained in the Exchange Offer Registration Statement includes a plan of distribution containing a statement to the above effect and the means by which Participating Broker-Dealers may resell the Exchange Securities, without naming the Participating Broker-Dealers or specifying the amount of Exchange Securities owned by them, such Prospectus may be delivered by Participating Broker-Dealers to satisfy their prospectus delivery obligation under the 1933 Act in connection with resales of Exchange Securities for their own accounts, so long as the Prospectus otherwise meets the requirements of the 1933 Act.

(b)            In light of the above, notwithstanding the other provisions of this Agreement, the Company and the Guarantors agree that the provisions of this Agreement as they relate to a Shelf Registration shall also apply to an Exchange Offer Registration to the extent, and with such reasonable modifications thereto as may be, reasonably requested by the Initial Purchasers or by one or more Participating Broker-Dealers, in each case as provided in clause (ii) below, in order to expedite or facilitate the disposition of any Exchange Securities by Participating Broker-Dealers consistent with the positions of the Staff recited in Section 4(a) above; provided that:

(i)             the Company and the Guarantors shall not be required to amend or supplement the Prospectus contained in the Exchange Offer Registration Statement with respect to a series of Registrable Securities, as would otherwise be contemplated by Section 3(i), (A) after the Participating Broker-Dealers shall have disposed of the Registrable Securities of such series or (B) for a period exceeding 180 days after the last Exchange Date with respect to such series (as such period may be extended pursuant to the penultimate paragraph of Section 3 of this Agreement) and Participating Broker-Dealers shall not be authorized by the Company and the Guarantors to deliver and shall not deliver such Prospectus after such period in connection with the resales contemplated by this Section 4; and

(ii)            the application of the Shelf Registration procedures set forth in Section 3 of this Agreement to an Exchange Offer Registration, to the extent not required by the positions of the Staff of the SEC or the 1933 Act and the rules and regulations thereunder, will be in conformity with the reasonable request to the Company and the Guarantors by the Initial Purchasers or with the reasonable request in writing to the Company and the Guarantors by one or more broker-dealers who certify to the Initial

Purchasers and the Company and the Guarantors in writing that they anticipate that they will be Participating Broker-Dealers; and provided further that, in connection with such application of the Shelf Registration procedures set forth in Section 3 to an Exchange Offer Registration, the Company and the Guarantors shall be obligated (x) to deal only with one entity representing the Participating Broker-Dealers, which shall be Goldman, Sachs & Co. unless it elects not to act as such representative, (y) to pay the fees and expenses of only one counsel representing the Participating Broker-Dealers, which shall be counsel to the Initial Purchasers unless such counsel elects not to so act and (z) to cause to be delivered only one, if any, “cold comfort” letter with respect to the Prospectus in the form existing on the last Exchange Date and with respect to each subsequent amendment or supplement, if any, effected during the period specified in clause (i) above.

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

5.              Indemnification and Contribution .

(a)            Each of the Company and the Guarantors agrees, jointly and severally, to indemnify and hold harmless the Initial Purchasers and each Holder, their respective affiliates, directors and officers and each Person, if any, who controls any Initial Purchasers or any Holder within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act, or is under common control with, or is controlled by, any Initial Purchasers or any Holder, from and against all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred by the Initial Purchaser, any Holder and their respective affiliates, directors and officers or any such controlling or affiliated Person in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement (or any amendment thereto) pursuant to which Exchange Securities or Registrable Securities were registered under the 1933 Act, including all documents incorporated therein by reference, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or caused by any untrue statement or alleged untrue statement of a material fact contained in any Prospectus (as amended or supplemented if the Company and the Guarantors shall have furnished any amendments or supplements thereto), any Free Writing Prospectus or any Issuer Information filed or required to be filed pursuant to Rule 433(d) under the 1933 Act, 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 the Initial Purchasers or any Holder furnished to the Company or the Guarantors in writing through Goldman, Sachs & Co. or any selling Holder expressly for use therein.  In connection with any Underwritten Offering permitted by Section 3, the Company and each of the Guarantors, jointly and severally, will also indemnify the Underwriters, if any, selling brokers, dealers and similar securities industry professionals participating in the distribution, their affiliates, officers and directors and each Person who controls such Persons (within the meaning of the 1933 Act and the 1934 Act) to the

same extent as provided above with respect to the indemnification of the Holders, if requested in connection with any Registration Statement, any Prospectus, any Free Writing Prospectus or any Issuer Information.

(b)            Each Holder agrees, severally and not jointly, to indemnify and hold harmless the Company, the Guarantors, the Initial Purchasers and their affiliates and the other selling Holders, and each of their respective directors, officers who sign the Registration Statement and each Person, if any, who controls the Company, the Guarantors, any Initial Purchaser and any other selling Holder within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act to the same extent as the foregoing indemnity from the Company and the Guarantors to the Initial Purchasers and the Holders, but only with reference to information relating to such Holder furnished to the Company and the Guarantors in writing by such Holder expressly for use in any Registration Statement (or any amendment thereto), any Prospectus (or any amendment or supplement thereto) or any Free Writing Prospectus.

(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 either paragraph (a) or paragraph (b) above, 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, (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 or (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action.  It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (a) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Initial Purchasers and all Persons, if any, who control any Initial Purchaser within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act, (b) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Company and the Guarantors, their directors, their officers who sign the Registration Statement and each Person, if any, who controls the Company or the Guarantors within the meaning of either such Section and (c) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Holders and all Persons, if any, who control any Holder within the meaning of either such Section, and that all such fees and expenses shall be reimbursed as they are incurred.  In such case involving the Initial Purchasers and Persons who control the Initial Purchasers, such firm shall be designated in writing by the Initial Purchasers.  In such case involving the Holders and such Persons who control Holders, such firm shall be designated in writing by the Majority Holders.  In all other cases, such firm shall be designated by the Company.  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.  Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party for such fees and expenses of counsel in accordance with such request prior to the date of such settlement.  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 such 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 claims that are the subject matter of such proceeding and (ii) does not include any statements as to or any findings of fault, culpability or failure to act by or on behalf of any indemnified party.

(d)            If the indemnification provided for in paragraph (a) or paragraph (b) of this Section 5 is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties 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 fault of the Company and the Guarantors, on the one hand, and the Holders, 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, on the one hand, or by the Holders, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.  The Holders’ respective obligations to contribute pursuant to this Section 5(d) are several in proportion to the respective principal amount of Registrable Securities of such Holder that were registered pursuant to a Registration Statement.

(e)            The Company, the Guarantors and each Holder agree that it would not be just or equitable if contribution pursuant to this Section 5 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above.  The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim.  Notwithstanding the provisions of this Section 5, no Holder shall be required to indemnify or contribute any amount in excess of the amount by which the total price at which Registrable Securities were sold by such Holder exceeds the amount of any damages

that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.  No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.  The remedies provided for in this Section 5 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

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

Ladies and Gentlemen:

Introductory .  Steel Dynamics, Inc., an Indiana corporation (the “Company”), proposes to issue and sell to Goldman, Sachs & Co. (“Goldman Sachs”), Merrill Lynch, Pierce, Fenner & Smith Incorporated (“Merrill Lynch”), Morgan Stanley & Co. LLC (“Morgan Stanley”) and the other several Initial Purchasers named in Schedule I and Schedule II (together, the “Initial Purchasers”), acting severally and not jointly, the respective amounts set forth in such Schedule I of $700,000,000 aggregate principal amount of the Company’s 5.125% Senior Notes due 2021 (the “2021 Notes”) and the respective amounts set forth in such Schedule II of $500,000,000 aggregate principal amount of the Company’s 5.500% Senior Notes due 2024 (the “2024 Notes” and, together with the 2021 Notes, the “Notes”).  Goldman Sachs, Merrill Lynch and Morgan Stanley have agreed to act as the representatives of the several Initial Purchasers (the “Representatives”) in connection with the offering and sale of the Notes.

The 2021 Notes and related Guarantees will be issued pursuant to an indenture to be dated as of the Closing Date (the “2021 Initial Indenture”), among the Company, the Guarantors (as defined below) and Wells Fargo Bank, National Association, as trustee (the “2021 Trustee”).  The 2024 Notes and related Guarantees will be issued pursuant to an indenture to be dated as of the Closing Date (the “2024 Initial Indenture” and, together with the 2021 Initial Indenture, the “Initial Indentures” and each, an “Initial Indenture”), among the Company, the Guarantors and Wells Fargo Bank, National Association, as trustee (the “2024 Trustee” and, together with the 2021 Trustee, the “Trustee”).  Notes will be issued only in book-entry form in the name of Cede & Co., as nominee of The Depository Trust Company (the “Depositary”) pursuant to a letter of representations, to be dated on or before the Closing Date (as defined in Section 2 hereof) (the “DTC Agreement”), among the Company, the Guarantors, the Trustee and the Depositary.

The Notes are being issued in connection with the acquisition of Severstal Columbus, LLC, a Delaware limited liability company (“Columbus”), by the Company.  On July 18, 2014, the Company entered into a membership interest purchase agreement with Severstal Columbus Holdings, LLC, a Delaware limited liability company (“Seller”), and Columbus (the “Acquisition Agreement”), pursuant to which the Company will acquire all of the membership interests of Columbus from Seller (the “Acquisition”).

On the Closing Date, the Company will enter into an escrow agreement (the “Escrow Agreement”), the form of which is attached hereto as Annex A, with the Trustee and Wells Fargo Bank, National Association, as escrow agent (the “Escrow Agent”), pursuant to which the gross proceeds of the offering of the Notes will be deposited into an escrow account (the “Escrow Account”).  Funds held in the Escrow Account (collectively, the “Escrow Property”) will be released in accordance with the conditions set forth in the Escrow Agreement for the purpose of consummating the Acquisition (the date of such release, the “Release Date”).  If the Release Date does not occur on or prior to April 18, 2015 (the “Outside Date”), or if the Acquisition Agreement is terminated prior to the Outside Date, or if the Company determines, in its discretion, that the escrow conditions cannot be satisfied by the Outside Date, the Escrow Property shall be released to the Trustee to redeem the Notes at a price equal to 100% of the aggregate principal amount of the 2021 Notes outstanding and at a price equal to 100% of the aggregate principal amount of the 2024 Notes outstanding, plus in each case accrued and unpaid interest from the Closing Date up to, but not including, the date of redemption (such date of redemption, the “Special Mandatory Redemption Date”).

The holders of the Notes will be entitled to the benefits of a registration rights agreement, to be dated as of the Closing Date (the “Registration Rights Agreement”), among the Company, the Guarantors and the Initial Purchasers, pursuant to which the Company and the Guarantors will agree to file with the Securities and Exchange Commission (the “Commission”), under the circumstances set forth therein, (i) a registration statement under the Securities Act of 1933, as amended (the “Securities Act,” which term, as used herein, includes the rules and regulations of the Commission promulgated thereunder), relating to another series of debt securities of the Company with terms substantially identical to the 2021 Notes (the “2021 Exchange Notes”) and to the 2024 Notes (the “2024 Exchange Notes” and, together with the 2021 Exchange Notes, the “Exchange Notes”) to be offered in exchange for the applicable series of Notes (the “Exchange Offer”) and (ii) to the extent required by the Registration Rights Agreement, a shelf registration statement pursuant to Rule 415 of the Securities Act relating to the resale by certain holders of the Notes, and in each case, to use its reasonable best efforts to cause any applicable registration statement to be declared effective.

The obligations of the Company under the Notes, the Exchange Notes and the Indentures will be unconditionally guaranteed on a senior unsecured basis, jointly and severally by (i) the Guarantors named in Schedule III and (ii) any other subsidiary of the Company that executes a supplemental indenture in accordance with the terms of the Indentures, including upon execution of the Supplemental Indentures (as defined below), Columbus, and their respective successors and assigns (collectively, the “Guarantors”), pursuant to the terms of the Indentures (each, a “Guarantee” and, collectively, the “Guarantees”).  Within three business days of the Release Date, Columbus will (i) execute a supplemental indenture to the 2021 Initial Indenture (the “2021 Supplemental Indenture”), providing for an unconditional guarantee of all of the Company’s obligations under the 2021 Initial Indenture and 2021 Notes on a senior unsecured basis (the “Columbus 2021 Guarantee”) and (ii) execute a supplemental indenture to the 2024 Initial Indenture (the “2024 Supplemental Indenture” and, together with the 2021 Supplemental Indenture, the “Supplemental Indentures” and each, a “Supplemental Indenture), providing for an unconditional guarantee of all of the Company’s obligations under the 2024 Indenture and 2024 Notes on a senior unsecured basis (the “Columbus 2024 Guarantee” and, together with the Columbus 2021 Guarantee, the “Columbus Guarantee”).  The 2021 Initial

2

Indenture, as supplemented by the 2021 Supplemental Indenture, is herein referred to as the “2021 Indenture”; the 2024 Initial Indenture, as supplemented by the 2024 Supplemental Indenture, is herein referred to as the “2024 Indenture”; and the 2021 Indenture and the 2024 Indenture are collectively referred to herein as the “Indentures” and each, an “Indenture.”

Unless specifically stated otherwise, the terms “Guarantors,” “Affiliate,” “affiliate” and “subsidiaries” and other similar terms (in each case, with respect to the Company) shall be deemed to include Columbus.  The Notes and the Guarantees thereof are herein collectively referred to as the “Securities”; and the Exchange Notes and the Guarantees are herein collectively referred to as the “Exchange Securities.”

Promptly following consummation of the Acquisition, (i)  Columbus shall execute and deliver a joinder agreement (the “Joinder Agreement”) substantially in the form attached hereto as Annex B, whereby Columbus will agree to observe and fully perform all of the rights, obligations and liabilities contemplated herein as if it were an original signatory hereto and (ii) Columbus shall execute and deliver a joinder agreement (the “Registration Rights Joinder Agreement”) substantially in the form attached hereto as Annex C, whereby Columbus will agree to observe and fully perform all of the rights, obligations and liabilities contemplated under the Registration Rights Agreement as if it were an original signatory thereto.

The Company understands that the Initial Purchasers propose to make an offering of the Securities on the terms and in the manner set forth herein and in the Pricing Disclosure Package (as defined below) and agrees that the Initial Purchasers may resell, subject to the conditions set forth herein, all or a portion of the Securities to purchasers (the “Subsequent Purchasers”) on the terms set forth in the Pricing Disclosure Package (the first time when sales of the Securities are made is referred to as the “Time of Sale”).  The Securities are to be offered and sold to or through the Initial Purchasers without being registered with the Commission under the Securities Act, in reliance upon exemptions therefrom.  Pursuant to the terms of the Securities and the Indentures, investors who acquire Securities shall be deemed to have agreed that Securities may only be resold or otherwise transferred, after the date hereof, if such Securities are registered for sale under the Securities Act or if an exemption from the registration requirements of the Securities Act is available (including the exemptions afforded by Rule 144A under the Securities Act (“Rule 144A”) or Regulation S under the Securities Act (“Regulation S”)).

The Company has prepared and delivered to each Initial Purchaser copies of a Preliminary Offering Memorandum, dated September 4, 2014 (the “Preliminary Offering Memorandum”), and has prepared and delivered to each Initial Purchaser copies of a Pricing Supplement attached hereto as Schedule V, dated September 4, 2014 (the “Pricing Supplement”), describing the terms of the Securities, each for use by such Initial Purchaser in connection with its solicitation of offers to purchase the Securities.  The Preliminary Offering Memorandum and the Pricing Supplement are herein referred to as the “Pricing Disclosure Package.”  Promptly after this Agreement is executed and delivered, the Company will prepare and deliver to each Initial Purchaser a final offering memorandum dated the date hereof (the “Final Offering Memorandum”).

All references herein to the terms “Pricing Disclosure Package” and “Final Offering Memorandum” shall be deemed to mean and include all information filed under the Securities

3

Exchange Act of 1934, as amended (the “Exchange Act,” which term, as used herein, includes the rules and regulations of the Commission promulgated thereunder), prior to the Time of Sale and incorporated by reference in the Pricing Disclosure Package (including the Preliminary Offering Memorandum) or the Final Offering Memorandum (as the case may be), and all references herein to the terms “amend,” “amendment” or “supplement” with respect to the Final Offering Memorandum shall be deemed to mean and include all information filed under the Exchange Act after the Time of Sale and incorporated by reference in the Final Offering Memorandum as of its date.

Each of the Company and the Guarantors (other than Columbus), and upon execution of the Joinder Agreement, Columbus, hereby confirms its agreements with the Initial Purchasers as follows:

SECTION 1.          Representations and Warranties .  Each of the Company and the Guarantors (other than Columbus), and upon execution of the Joinder Agreement, Columbus, jointly and severally, hereby represents, warrants and covenants to each Initial Purchaser that, as of the date hereof and as of the Closing Date (references in this Section 1 to the “Offering Memorandum” are to (x) the Pricing Disclosure Package in the case of representations and warranties made as of the date hereof and (y) each of the Pricing Disclosure Package and the Final Offering Memorandum in the case of representations and warranties made as of the Closing Date):

(a)            No Registration Required .  Subject to compliance by the Initial Purchasers with the representations and warranties set forth in Section 2 hereof and with the procedures set forth in Section 8 hereof, it is not necessary in connection with the offer, sale and delivery of the Securities to the Initial Purchasers and to each Subsequent Purchaser in the manner contemplated by this Agreement and the Offering Memorandum to register the Securities under the Securities Act or, until such time as the Exchange Securities may be issued pursuant to an effective registration statement, to qualify the Indentures under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act,” which term, as used herein, includes the rules and regulations of the Commission promulgated thereunder).

(b)            No Integration of Offerings or General Solicitation .  None of the Company, its affiliates (as such term is defined in Rule 501 under the Securities Act) (each, an “Affiliate”), or any person acting on its or any of their behalf (other than the Initial Purchasers, as to whom the Company makes no representation or warranty) has, directly or indirectly, solicited any offer to buy or offered to sell, or will, directly or indirectly, solicit any offer to buy or offer to sell, in the United States or to any United States citizen or resident, any security which is or would be integrated with the sale of the Securities in a manner that would require the Securities to be registered under the Securities Act.  None of the Company, its Affiliates, or any person acting on its or any of their behalf (other than the Initial Purchasers, as to whom the Company makes no representation or warranty) has engaged or will engage, in connection with the offering of the Securities, in any form of general solicitation or general advertising within the meaning of Rule 502 under the Securities Act.  With respect to those Securities sold in reliance upon Regulation S, (i) none of the Company, its Affiliates or any person acting on its or their behalf (other than the Initial Purchasers, as to whom the Company makes no representation or warranty) has engaged or will engage in any directed selling efforts within the meaning of Regulation S

(bb)          Periodic Review of Costs of Environmental Compliance .  In the ordinary course of business, the Company conducts a periodic review of the effect of Environmental Laws on the business, operations and properties of the Company and its subsidiaries (other than Columbus), in the course of which it identifies and evaluates associated costs and liabilities (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties).  On the basis of such review, the Company has reasonably concluded that such associated costs and liabilities for its current operations would not, singly or in the aggregate, have a Material Adverse Effect.  To the knowledge of the Company, the associated costs and liabilities associated with the effect of Environmental Laws on the business, operations and properties of Columbus (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties) would not, singly or in the aggregate, have a Material Adverse Effect.

12

involved, except as may be expressly stated in the related notes thereto.  The supporting schedules, if any, present fairly in accordance with GAAP the information required to be stated therein.  The summary financial information included in the Offering Memorandum presents fairly the information shown therein and has been compiled on a basis consistent with that of the audited financial statements incorporated by reference in the Offering Memorandum.  All disclosures contained in the Offering Memorandum regarding “non-GAAP financial measures” (as such term is defined by the rules and regulations of the Commission) comply with Regulation G under the Exchange Act and Item 10 of Regulation S-K of the Securities Act, to the extent applicable.  In addition, the pro forma financial statements of the Company and its subsidiaries and the related notes thereto included in the Offering Memorandum present fairly, in all material respects, the information shown therein, have been prepared in accordance with the Commission’s rules and guidelines with respect to pro forma financial statements and have been properly compiled on the bases described therein, and the assumptions used in the preparation thereof are reasonable and the adjustments used therein are appropriate to give effect to the transactions and circumstances referred to therein.  The interactive data in eXtensible Business Reporting Language included or incorporated by reference in the Offering Memorandum and the Pricing Disclosure Package fairly present the information called for in all material respects and are prepared in accordance with the Commission’s rules and guidelines applicable thereto.

such written communication for review and will not use, authorize, approve or distribute any such written communication to which the Representatives reasonably objects.

(b)            Amendments and Supplements to the Final Offering Memorandum and Other Securities Act Matters .  If, prior to the later of (x) the Closing Date and (y) the completion of the placement of the Securities by the Initial Purchasers with the Subsequent Purchasers, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Final Offering Memorandum (or the Pricing Disclosure Package in the event the Final Offering Memorandum is not yet available), as then amended or supplemented, in order to make the statements therein, in the light of the circumstances when the Final Offering Memorandum (or the Pricing Disclosure Package in the event the Final Offering Memorandum is not yet available) is delivered to a Subsequent Purchaser, not misleading, or if in the judgment of the Representatives or counsel for the Initial Purchasers it is otherwise necessary to amend or supplement the Final Offering Memorandum (or the Pricing Disclosure Package in the event the Final Offering Memorandum is not yet available) to comply with law, the Company agrees to promptly notify the Initial Purchasers and promptly prepare (subject to Section 3(a) hereof), and furnish at its own expense to the Initial Purchasers, amendments or supplements to the Final Offering Memorandum (or the Pricing Disclosure Package in the event the Final Offering Memorandum is not yet available) so that the statements in the Final Offering Memorandum (or the Pricing Disclosure Package in the event the Final Offering Memorandum is not yet available) as so amended or supplemented will not, in the light of the circumstances at the Closing Date and at the time of sale of Securities, be misleading or so that the Final Offering Memorandum (or the Pricing Disclosure Package in the event the Final Offering Memorandum is not yet available), as amended or supplemented, will comply with all applicable law.

Following the consummation of the Exchange Offer or the effectiveness of an applicable shelf registration statement, in each case, if necessary under the terms of the Registration Rights Agreement, and for so long as the Securities are outstanding if, in the judgment of the Representatives, the Initial Purchasers or any of their affiliates (as such term is defined in the Securities Act) are required to deliver a prospectus in connection with sales of, or market-making activities with respect to, the Securities, to periodically amend the applicable registration statement so that the information contained therein complies with the requirements of Section 10 of the Securities Act, to amend the applicable registration statement or supplement the related prospectus or the documents incorporated therein when necessary to reflect any material changes in the information provided therein so that the registration statement and the prospectus will not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances existing as of the date the prospectus is so delivered, not misleading and to provide the Initial Purchasers with copies of each amendment or supplement filed and such other documents as the Initial Purchasers may reasonably request.

(b)            Indemnification of the Company and the Guarantors .  Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company, each Guarantor (other than Columbus, and upon execution of the Joinder Agreement, Columbus), each of their respective directors and officers and each person, if any, who controls the Company or any Guarantor within the meaning of the Securities Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which the Company, any Guarantor or any such director, officer or controlling person may become subject, under the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Initial Purchaser or otherwise permitted by Section 9(d) hereof), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, the Pricing Supplement, the Final Offering Memorandum (or any amendment or supplement thereto) or any Company Supplemental Disclosure Document, or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, 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 the Preliminary Offering Memorandum, the Pricing Supplement, the Final Offering Memorandum (or any amendment or supplement thereto) or any Company Supplemental Disclosure Document, in reliance upon and in conformity with written information furnished to the Company by the Representatives expressly for use therein; and to reimburse the Company, any Guarantor and each such director, officer or controlling person for any and all expenses (including the fees and disbursements of counsel) as such expenses are reasonably incurred by the Company, any Guarantor or such director, officer or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action.  Each of the Company and the Guarantors hereby acknowledges that the only information that the Initial Purchasers through the Representatives have furnished to the Company expressly for use in the Preliminary Offering Memorandum, the Pricing Supplement or the Final Offering Memorandum (or any amendment or supplement thereto) are the statements set forth in the second and third sentences of the second paragraph and the sixth, seventh and eighth paragraphs under the caption “Plan of Distribution” in the Preliminary Offering Memorandum or the Final Offering Memorandum.  The indemnity agreement set forth in this Section 9(b) shall be in addition to any liabilities that each Initial Purchaser may otherwise have.

(c)            Notifications and Other Indemnification Procedures .  Promptly after receipt by an indemnified party under this Section 9 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 9, notify the indemnifying party in writing of the commencement thereof, but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party for contribution or otherwise than under the indemnity agreement contained in this Section 9 or to the extent it is not materially prejudiced as a proximate result of such failure.  In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to

27

assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided , however , if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties.  Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 9 for any fees and expenses of counsel subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the next preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (together with local counsel), representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party.

(d)            Settlements .  The indemnifying party under this Section 9 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 against any loss, claim, damage, liability or expense by reason of such settlement or judgment.  Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by this Section 9, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement.  No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (ii) does not include any statements as to or any findings of fault, culpability or failure to act by or on behalf of any indemnified party.

SECTION 10.        Contribution .  If the indemnification provided for in Section 9 hereof is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses

28

referred to therein (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 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 Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, in connection with the statements or omissions or inaccuracies in the representations and warranties herein 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 Initial Purchasers, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, and the total fees received by the Initial Purchasers bear to the aggregate initial offering price of the Securities.  The relative fault of the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact, any such omission or alleged omission to state a material fact, or any such inaccurate or alleged inaccurate representation or warranty relates to information supplied by the Company and the Guarantors, on the one hand, or the Initial Purchasers, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or inaccuracy.

The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 9 hereof, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim.  The provisions set forth in Section 9 hereof with respect to notice of commencement of any action shall apply if a claim for contribution is to be made under this Section 10; provided , however , that no additional notice shall be required with respect to any action for which notice has been given under Section 9 hereof for purposes of indemnification.

The Company, the Guarantors and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 10 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 which does not take account of the equitable considerations referred to in this Section 10.

Notwithstanding the provisions of this Section 10, no Initial Purchaser shall be required to contribute any amount in excess of the fee received by such Initial Purchaser in connection with the Securities distributed by it.  No person guilty of fraudulent misrepresentation (within the meaning of Section 11 of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.  The Initial Purchasers’ obligations to contribute pursuant to this Section 10 are several, and not joint, in proportion to their respective commitments as set forth opposite their names in Schedules I and II.  For purposes of this Section 10, each affiliate, director, officer and employee of an Initial Purchaser and each person, if any, who controls an Initial Purchaser within the meaning of the Securities Act and the

29

Exchange Act shall have the same rights to contribution as such Initial Purchaser, and each director of the Company or any Guarantor, and each person, if any, who controls the Company or any Guarantor with the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Company and the Guarantors.

SECTION 11.        Termination of this Agreement .  The Initial Purchasers may terminate this Agreement by notice given by the Representatives 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 Nasdaq Global Market, the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (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 the judgment of the Representatives, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in the judgment of the Representatives, impracticable or inadvisable to proceed with the offer, sale or delivery of the Securities on the terms and in the manner contemplated in the Offering Memorandum; (vi) in the judgment of the Representatives there shall have occurred any Material Adverse Change; or (vii) the Company or any of its subsidiaries shall have sustained a loss by strike, fire, flood, earthquake, accident or other calamity of such character as in the judgment of the Representatives may interfere materially with the conduct of the business and operations of the Company and its subsidiaries, taken as a whole, regardless of whether or not such loss shall have been insured.  Any termination pursuant to this Section 11 shall be without liability on the part of (i) the Company or any Guarantor to any Initial Purchaser, except that the Company and the Guarantors shall be obligated to reimburse the expenses of the Initial Purchasers pursuant to Sections 5 and 7 hereof, (ii) any Initial Purchaser to the Company, or (iii) any party hereto to any other party except that the provisions of Sections 9 and 10 hereof shall at all times be effective and shall survive such termination.

SECTION 12.        Representations and Indemnities to Survive Delivery .  The respective indemnities, agreements, representations, warranties and other statements of the Company, the Guarantors, their respective officers and the several Initial Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Initial Purchaser, the Company, any Guarantor or any of their partners, officers or directors or any controlling person, as the case may be, and will survive delivery of and payment for the Securities sold hereunder and any termination of this Agreement.

SECTION 14.        Successors .  This Agreement will inure to the benefit of and be binding upon the parties hereto, including any substitute Initial Purchasers pursuant to Section 18 hereof, and to the benefit of the indemnified parties referred to in Sections 9 and 10 hereof, and in each case their respective successors, and no other person will have any right or obligation hereunder.  The term “successors” shall not include any Subsequent Purchaser or other purchaser of the Securities as such from any of the Initial Purchasers merely by reason of such purchase.

SECTION 15.        Partial Unenforceability .  The invalidity or unenforceability of any section, paragraph or provision of this Agreement shall not affect the validity or enforceability of any other section, paragraph or provision hereof.  If any section, paragraph or provision of this Agreement is for any reason determined to be invalid or unenforceable, there shall be deemed to be made such minor changes (and only such minor changes) as are necessary to make it valid and enforceable.

SECTION 16.        Governing Law Provisions .  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SUCH STATE.

SECTION 17.        Consent to Jurisdiction .  Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby (“Related Proceedings”) may be instituted in the federal courts of the United States of America located in the City and County of New York or the courts of the State of New York in each case located in the City and County of New York (collectively, the “Specified Courts”), and each party irrevocably submits to the exclusive jurisdiction (except for suits, actions, or proceedings instituted in regard to the enforcement of a judgment of any Specified Court in a Related Proceeding, as to which such jurisdiction is non-exclusive) of the Specified Courts in any Related Proceeding.  Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any Related Proceeding brought in any Specified Court.  The parties irrevocably and unconditionally waive any objection to the laying of venue of any Specified Proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any Specified Court that any Related Proceeding brought in any Specified Court has been brought in an inconvenient forum.

SECTION 18.        Default of One or More of the Several Initial Purchasers .  If any one or more of the several Initial Purchasers shall fail or refuse to purchase Securities that it or they have agreed to purchase hereunder on the Closing Date, and the aggregate number of Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase does not exceed 10% of the aggregate number of the Securities to be purchased on such date, the other Initial Purchasers shall be obligated, severally, in the proportions that the number of Securities set forth opposite their respective names on Schedules I and II, as applicable, bears to the aggregate number of Securities set forth opposite the names of all such non-defaulting Initial Purchasers, or in such other proportions as may be specified by the Initial Purchasers with the consent of the non-defaulting Initial Purchasers, to purchase the Securities which such

32

defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase on the Closing Date.  If any one or more of the Initial Purchasers shall fail or refuse to purchase Securities and the aggregate number of Securities with respect to which such default occurs exceeds 10% of the aggregate number of Securities to be purchased on the Closing Date, and arrangements satisfactory to the Initial Purchasers and the Company for the purchase of such Securities are not made within 48 hours after such default, this Agreement shall terminate without liability of any party to any other party except that the provisions of Sections 5, 7, 9 and 10 hereof shall at all times be effective and shall survive such termination.  In any such case either the Initial Purchasers or the Company shall have the right to postpone the Closing Date, as the case may be, but in no event for longer than seven days in order that the required changes, if any, to the Final Offering Memorandum or any other documents or arrangements may be effected.

As used in this Agreement, the term “Initial Purchaser” shall be deemed to include any person substituted for a defaulting Initial Purchaser under this Section 18.  Any action taken under this Section 18 shall not relieve any defaulting Initial Purchaser from liability in respect of any default of such Initial Purchaser under this Agreement.

SECTION 19.        No Advisory or Fiduciary Responsibility .  Each of the Company and the Guarantors acknowledges and agrees that:  (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company and the Guarantors, on the one hand, and the several Initial Purchasers, on the other hand, and the Company and the Guarantors are capable of evaluating and understanding and understand and accept the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with each transaction contemplated hereby and the process leading to such transaction each Initial Purchaser is and has been acting solely as a principal and is not the agent or fiduciary of the Company, the Guarantors or their respective affiliates, stockholders, creditors or employees or any other party; (iii) no Initial Purchaser has assumed or will assume an advisory or fiduciary responsibility in favor of the Company or the Guarantors with respect to any of the transactions contemplated hereby or the process leading thereto (irrespective of whether such Initial Purchaser has advised or is currently advising the Company or the Guarantors on other matters) or any other obligation to the Company and the Guarantors except the obligations expressly set forth in this Agreement; (iv) the several Initial Purchasers and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and the Guarantors and that the several Initial Purchasers have no obligation to disclose any of such interests by virtue of any fiduciary or advisory relationship; and (v) the Initial Purchasers have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company and the Guarantors have consulted their own legal, accounting, regulatory and tax advisors to the extent they deemed appropriate.

This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company, the Guarantors and the several Initial Purchasers, or any of them, with respect to the subject matter hereof.  The Company and the Guarantors hereby waive and release, to the fullest extent permitted by law, any claims that the Company and the Guarantors

33

may have against the several Initial Purchasers with respect to any breach or alleged breach of fiduciary duty.

SECTION 20.        General Provisions .  This Agreement may be executed in two or more counterparts, each one of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.  Delivery of an executed counterpart of a signature page to this Agreement by telecopier, facsimile or other electronic transmission shall be effective as delivery of a manually executed counterpart thereof.  This Agreement may not be amended or modified unless in writing by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit.  The section headings herein are for the convenience of the parties only and shall not affect the construction or interpretation of this Agreement.
