Subject to the terms and conditions herein set forth, (a) the Selling Stockholder agrees to sell to each of the Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from the Selling Stockholder, at a purchase price per share of $15.71625, the number of Firm Shares (to be adjusted by you so as to eliminate fractional shares) determined by multiplying the aggregate number of Firm Shares to be sold by the Selling Stockholder as set forth in Schedule II hereto by a fraction, the numerator of which is the aggregate number of Firm Shares to be purchased by such Underwriter as set forth opposite the name of such Underwriter in Schedule I hereto and the denominator of which is the aggregate number of Firm Shares to be purchased by all of the Underwriters from the Selling Stockholder hereunder and (b) in the event and to the extent that the Underwriters shall exercise the election to purchase Optional Shares as provided below, the Selling Stockholder agrees to sell to each of the Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from the Selling Stockholder, at the purchase price per share set forth in clause (a) of this Section 2, that portion of the number of Optional Shares as to which such election shall have been exercised (to be adjusted by you so as to eliminate fractional shares) determined by multiplying such number of Optional Shares by a fraction the numerator of which is the maximum number of Optional Shares which such Underwriter is entitled to purchase as set forth opposite the name of such Underwriter in Schedule I hereto and the denominator of which is the maximum number of Optional Shares that all of the Underwriters are entitled to purchase hereunder.

The Selling Stockholder, as and to the extent indicated in Schedule II hereto, hereby grants to the Underwriters the right to purchase at their election up to 750,000 Optional Shares, at the purchase price per share set forth in the paragraph above, for the sole purpose of covering sales of shares in excess of the number of Firm Shares. Any such election to purchase Optional Shares may be exercised only by written notice from you to the Selling Stockholder, given within a period of 30 calendar days after the date of this Agreement and setting forth the aggregate number of Optional Shares to be purchased and the date on which such Optional Shares are to be delivered, as determined by you but in no event earlier than the First Time of Delivery (as defined in Section 4 hereof) or, unless you and the Selling Stockholder otherwise agree in writing, no earlier than two and no later than ten business days after the date of such notice.

3. Upon the authorization by you of the release of the Firm Shares, the several Underwriters propose to offer the Firm Shares for sale upon the terms and conditions set forth in the Prospectus.

4. (a) The Shares to be purchased by each Underwriter hereunder, in book-entry form, and in such authorized denominations and registered in such names as Xxxxxxx, Xxxxx & Co. may request upon at least forty-eight hours’ prior notice to the Selling Stockholder shall be delivered by or on behalf of the Selling Stockholder to Xxxxxxx, Sachs & Co., through the facilities of the Depository Trust Company (“DTC”), for the account of such Underwriter, against payment by or on behalf of such Underwriter of the purchase price therefor by wire transfer of Federal (same-day) funds to the account specified by the Selling Stockholder to Xxxxxxx, Xxxxx & Co. at least forty-eight hours in advance. The Company and the Selling Stockholder will cause the certificates representing the Shares to be made available for checking and packaging at least twenty-four hours prior to the Time of Delivery (as defined below) with respect thereto at the office of DTC or its designated custodian (the “Designated Office”). The time and date of such delivery and payment shall be, with respect to the Firm Shares, 9:30 a.m., New York time, on October 1, 2013, or such other time and date as Xxxxxxx, Sachs & Co. and the Selling Stockholder may agree upon in writing, and, with respect to the Optional Shares, 9:30 a.m., New York time, on the date specified by Xxxxxxx, Xxxxx & Co. in the written notice given by Xxxxxxx, Sachs & Co. of the Underwriters’ election to purchase such Optional Shares, or such other time and date as Xxxxxxx, Xxxxx & Co. and the Selling Stockholder may agree upon in writing. Such time and date for delivery of the Firm Shares is herein called the “First Time of Delivery”, such time and date for delivery of the Optional Shares, if not the First Time of Delivery, is herein called the “Second Time of Delivery”, and each such time and date for delivery is herein called a “Time of Delivery”.

(b) The documents to be delivered at each Time of Delivery by or on behalf of the parties hereto pursuant to Section 8 hereof, including the cross receipt for the Shares and any additional documents requested by the Underwriters pursuant to Section 8(k) hereof, will be delivered at the offices of Cravath, Swaine & Xxxxx LLP, 000 Xxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000 (the “Closing Location”), and the Shares will be delivered at the Designated Office, all at such Time of Delivery. A meeting will be held at the Closing Location at 2:00 p.m., New York City time, on the New York Business Day next preceding such Time of Delivery, at which meeting the final drafts of the documents to be delivered pursuant to the preceding sentence will be available for review by the parties hereto. For the purposes of this Section 4, “New York Business Day” shall mean each Monday, Tuesday, Wednesday, Thursday and Friday which is not a day on which banking institutions in New York are generally authorized or obligated by law or executive order to close.

(h) [Intentionally Omitted];

(i) To file with the Commission such information on Form 10-Q or Form 10-K as may be required by Rule 463 under the Act;

6. (a) The Company represents and agrees that, without the prior consent of the Representatives, it has not made and will not make any offer relating to the Shares that would constitute a “free writing prospectus” as defined in Rule 405 under the Act; each Underwriter represents and agrees that, without the prior consent of the Company and the Representatives, it has not made and will not make any offer relating to the Shares that would constitute a free writing prospectus; the Selling Stockholder represents and agrees that, without the prior written consent of the Company and the Representatives, it has not made and will not make any offer relating to the Shares that would constitute a free writing prospectus; any such free writing prospectus the use of which has been consented to by the Company, the Selling Stockholder and the Representatives is listed on Schedule III hereto;

7. The Company and the Selling Stockholder covenant and agree with one another and with the several Underwriters that the Company will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Company’s counsel and accountants in connection with the registration of the Shares under the Act and all other expenses in connection with the preparation, printing, reproduction and filing of the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus and the Prospectus and amendments and supplements thereto and the mailing and delivering of copies thereof to the Underwriters and dealers; (ii) the cost of printing or producing any Agreement among Underwriters, this Agreement and any other documents in connection with the offering, purchase, sale and delivery of the Shares; (iii) all fees and expenses in connection with listing the Shares on the NYSE; (iv) the filing fees incident to, and the reasonable and documented fees and disbursements of counsel for the Underwriters in connection with, any required review by FINRA of the terms of the sale of the Shares; (v) the cost of preparing stock certificates; (vi) the cost and charges of any transfer agent or registrar; and (vii) all other costs and expenses incident to the performance of its obligations hereunder which are not otherwise specifically provided for in this Section; provided, however, that reimbursements to the Underwriters, if any, shall be limited to expenses actually incurred and provided further that in the case of clause (iv) hereof the Company shall not be required to reimburse expenses of counsel for the Underwriters in excess of $15,000 in the aggregate. It is understood, however, that, except as provided in this Section, and Sections 9 and 12 hereof, the Underwriters will pay all of their own costs and expenses, including the fees of their counsel, stock transfer taxes on resale of any of the Shares by them, and any advertising expenses connected with any offers they may make.

8. The obligations of the Underwriters hereunder, as to the Shares to be delivered at each Time of Delivery, shall be subject, in their discretion, to the condition that all representations and warranties and other statements of the Company and of the Selling Stockholder herein are, at and as of such Time of Delivery, true and correct, the condition that the Company and the Selling Stockholder shall have performed all of its and their obligations hereunder theretofore to be performed, and the following additional conditions:

9. (a) The Company will indemnify and hold harmless each Underwriter, its partners, members, directors, officers and its affiliates and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim, as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with the Underwriter Information.

(b) The Selling Stockholder will indemnify and hold harmless each Underwriter, its partners, members, directors, officers and its affiliates and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement or the Prospectus, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any Preliminary Prospectus, the Registration Statement or the Prospectus or any such amendment or supplement in reliance upon and in conformity with the Selling Stockholder Information; and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Selling Stockholder shall not be liable in any such case (i) to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, the Registration Statement or the Prospectus or any such amendment or supplement in reliance upon and in conformity with the Underwriter Information or (ii) for any amount arising under this subsection (b) in excess of the proceeds from the Offering after deducting any underwriting discounts and commissions received by the Underwriters, but without deducting any expenses of the Company or the Selling Stockholder (the “Net Proceeds”).

(c) Each Underwriter will indemnify and hold harmless the Company and the Selling Stockholder and each of their respective partners, members, directors, officers and affiliates and each

person, if any, who controls the Company and the Selling Stockholder within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which the Company or the Selling Stockholder may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with the Underwriter Information; and will reimburse the Company and the Selling Stockholder for any legal or other expenses reasonably incurred by the Company or the Selling Stockholder in connection with investigating or defending any such action or claim as such expenses are incurred.

(d) Promptly after receipt by an indemnified party under subsection (a), (b) or (c) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party. The indemnifying party shall not be required to indemnify the indemnified party for any amount paid or payable by the indemnified party for any settlement of any action, proceeding or investigation made without the written consent of the indemnifying party, which consent shall not be unreasonably withheld or delayed.

(e) If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a), (b) or (c) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is

appropriate to reflect the relative benefits received by the Company and the Selling Stockholder on the one hand and the Underwriters on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (d) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and the Selling Stockholder on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Stockholder on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total Net Proceeds from the offering received by the Selling Stockholder bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Selling Stockholder Information on the one hand or the Underwriter Information on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Selling Stockholder and the Underwriters agree that it would not be just and equitable if contributions pursuant to this subsection (e) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (e) shall be deemed to include 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 subsection (e), (i) no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission; and (ii) the Selling Stockholder shall not be required to contribute (x) in any circumstances in which the losses, claims, damages, liabilities or expenses arose from matters other than the Selling Stockholder Information or (y) any amount in excess of the amount by which the Net Proceeds exceed the amount of any damages which the Selling Stockholder 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 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (e) to contribute are several in proportion to their respective underwriting obligations and not joint.

(f) The obligations of the Company and the Selling Stockholder under this Section 9 shall be in addition to any liability which the Company and the Selling Stockholder may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Act and each broker-dealer affiliate of any Underwriter; and the obligations of the Underwriters under this Section 9 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company or the Selling Stockholder within the meaning of the Act.

10. (a) If any Underwriter shall default in its obligation to purchase the Shares which it has agreed to purchase hereunder at a Time of Delivery, you may in your discretion arrange for you or another party or other parties to purchase such Shares on the terms contained herein. If within thirty-six hours after such default by any Underwriter you do not arrange for the purchase of such Shares, then the Selling Stockholder shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to you to purchase such Shares on such terms. In the event that, within the respective prescribed periods, you notify the Selling Stockholder that you have so arranged for the purchase of such Shares, or the Selling Stockholder notifies you that they have so arranged for the purchase of such Shares, you or the Selling Stockholder shall have the right to postpone a Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments to the Registration Statement or the Prospectus which in your opinion may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Shares.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you and the Selling Stockholder as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased does not exceed one-eleventh of the aggregate number of all the Shares to be purchased at such Time of Delivery, then the Selling Stockholder shall have the right to require each non-defaulting Underwriter to purchase the number of Shares which such Underwriter agreed to purchase hereunder at such Time of Delivery and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Shares which such Underwriter agreed to purchase hereunder) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you and the Selling Stockholder as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased exceeds one-eleventh of the aggregate number of all the Shares to be purchased at such Time of Delivery, or if the Selling Stockholder shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Shares of a defaulting Underwriter or Underwriters, then this Agreement (or, with respect to the Second Time of Delivery, the obligations of the Underwriters to purchase and of the Selling Stockholder to sell the Optional Shares) shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Selling Stockholder, except for the expenses to be borne by the Selling Stockholder and the Underwriters as provided in Section 7 hereof and the indemnity and contribution agreements in Section 9 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

11. The respective indemnities, agreements, representations, warranties and other statements of the Company, the Selling Stockholder and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, or the Company, or the Selling Stockholder, or any officer or director or controlling person of the Company, or any controlling person of the Selling Stockholder, and shall survive delivery of and payment for the Shares.

12. If this Agreement shall be terminated pursuant to Section 10 hereof, neither the Company nor the Selling Stockholder shall then be under any liability to any Underwriter except as provided in Sections 7 and 9 hereof; but, if for any other reason any Shares are not delivered by or on behalf of the Selling Stockholder as provided herein, the Selling Stockholder will reimburse the Underwriters through you for all out-of-pocket expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Shares not so delivered, but the Company and the Selling Stockholder shall then be under no further liability to any Underwriter in respect of the Shares not so delivered except as provided in Sections 7 and 9 hereof.

13. In all dealings hereunder, the Representatives jointly shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by the Representatives.

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to the Representatives at Xxxxxxx, Xxxxx & Co., 000 Xxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention: Registration Department and Xxxxxx Xxxxxxx & Co. LLC, 0000 Xxxxxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention: GCM Syndicate Desk; if to the Selling Stockholder shall be delivered or sent by mail, telex or facsimile transmission c/o KPS Capital Partners, LP, 000 Xxxxxxxxx Xxxxxx, 00xx Xxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention Xxxx Xxxxx; and if to the Company shall be delivered or sent by mail, telex or facsimile transmission to the address of the Company set forth in the Registration Statement, Attention: Secretary; provided, however, that any notice to an Underwriter pursuant to Section 9(d) hereof shall be delivered or sent by mail, telex or facsimile transmission to such Underwriter at its address set forth in its Underwriters’ Questionnaire or telex constituting such Questionnaire, which address will be supplied to the Company or the Selling Stockholder by you on request; provided, however, that notices under subsection 5(e) shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to the Representatives at Xxxxxxx, Xxxxx & Co., 000 Xxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention: Control Room and Xxxxxx Xxxxxxx & Co. LLC, 0000 Xxxxxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention: Control Room. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

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

14. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Company and the Selling Stockholder and, to the extent provided in Sections 9 and 11 hereof, the officers and directors of the Company and each person who controls the Company, the Selling Stockholder or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Shares from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

15. Time shall be of the essence of this Agreement. As used herein, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

16. The Company and the Selling Stockholder acknowledge and agree that (i) the purchase and sale of the Shares pursuant to this Agreement is an arm’s-length commercial transaction between the Company and the Selling Stockholder, on the one hand, and the several Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not the agent or fiduciary of the Company or the Selling Stockholder, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Company or the Selling Stockholder with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company or the Selling Stockholder on other matters) or any other obligation to the Company or the Selling Stockholder except the obligations expressly set forth in this Agreement and (iv) the Company and the Selling Stockholder have consulted their respective own legal and financial advisors to the extent they deemed appropriate. The Company and the Selling Stockholder agree that they will not claim that the Underwriters, or any of them, have rendered advisory services of any nature or respect, or owe a fiduciary or similar duty to the Company or the Selling Stockholder, in connection with such transaction or the process leading thereto.

17. This Agreement supersedes all prior agreements and understandings (whether written or oral) among the Company, the Selling Stockholder and the Underwriters, or any of them, with respect to the subject matter hereof.

18. THIS AGREEMENT AND ANY MATTERS RELATED TO THIS TRANSACTION SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAWS THAT WOULD RESULT IN THE APPLICATION OF ANY LAW OTHER THAN THE LAWS OF THE STATE OF NEW YORK. The parties hereto agree that any suit or proceeding arising in respect of this Agreement or our engagement will be tried exclusively in the U.S. District Court for the Southern District of New York or, if that court does not have subject matter jurisdiction, in any state court located in The City and County of New York and the parties hereto agree to submit to the jurisdiction of, and to venue in, such courts.

19. The Company and each of the Underwriters and the Selling Stockholder hereby irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

20. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same instrument.

21. Notwithstanding anything herein to the contrary, the Company and the Selling Stockholder are authorized to disclose to any persons the U.S. federal and state income tax treatment and tax structure of the potential transaction and all materials of any kind (including tax opinions and other tax analyses) provided to the Company and the Selling Stockholder relating to that treatment and structure, without the Underwriters imposing any limitation of any kind. However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, “tax structure” is limited to any facts that may be relevant to that treatment.

If the foregoing is in accordance with your understanding, please sign and return to us six counterparts hereof, and upon the acceptance hereof by you, on behalf of each of the Underwriters, this letter and such acceptance hereof shall constitute a binding agreement among each of the Underwriters, the Company and each of the Selling Stockholder.

Re: Global Brass and Copper Holdings, Inc. - Lock-Up Agreement

Ladies and Gentlemen:

The undersigned understands that you, as representatives (the “Representatives”), propose to enter into an underwriting agreement (the “Underwriting Agreement”) on behalf of the several Underwriters named in Schedule I to such agreement (collectively, the “Underwriters”), with Global Brass and Copper Holdings, Inc., a Delaware corporation (the “Company”), and with the selling stockholder named in Schedule II to such agreement, providing for a public offering (the “Public Offering”) of shares (the “Shares”) of common stock of the Company with a par value of $0.01 (the “Common Stock”) pursuant to a Registration Statement on Form S-1 to be filed with the Securities and Exchange Commission (the “SEC”).

In consideration of the agreement by the Underwriters to offer and sell the Shares, and of other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, during the period specified in the following paragraph (the “Lock-Up Period”), the undersigned will not offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of any shares of Common Stock of the Company, or any options or warrants to purchase any shares of Common Stock of the Company, or any securities convertible into, exchangeable for or that represent the right to receive shares of Common Stock of the Company, whether now owned or hereafter acquired, owned directly by the undersigned (including holding as a custodian) or with respect to which the undersigned has beneficial ownership within the rules and regulations of the SEC (collectively the “Undersigned’s Shares”). The foregoing restriction is expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the Undersigned’s Shares even if such Shares would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the Undersigned’s Shares or with respect to any security that includes, relates to, or derives any significant part of its value from such Shares.

A-5

The initial Lock-Up Period will commence on the date of this Lock-Up Agreement and continue for [—]¹ days after the public offering date set forth on the final prospectus used to sell the Shares (the “Public Offering Date”) pursuant to the Underwriting Agreement; provided, however, that if (1) during the last 17 days of the initial Lock-Up Period, the Company releases earnings results or announces material news or a material event or (2) prior to the expiration of the initial Lock-Up Period, the Company announces that it will release earnings results during the 15-day period following the last day of the initial Lock-Up Period, then in each case the Lock-Up Period will be automatically extended until the expiration of the 18-day period beginning on the date of release of the earnings results or the announcement of the material news or material event, as applicable, unless the Representatives waive, in writing, such extension.

If the undersigned is an officer or director of the Company, (i) the Representatives agree that, at least three business days before the effective date of any release or waiver of the foregoing restrictions in connection with a transfer of shares of Common Stock, the Representatives will notify the Company of the impending release or waiver, and (ii) the Company has agreed in the Underwriting Agreement to announce the impending release or waiver by press release through a major news service at least two business days before the effective date of the release or waiver to the extent required by FINRA Rule 5131(d)(2)(B). Any release or waiver granted by the Representatives hereunder to any such officer or director shall only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply if (a) the release or waiver is effected solely to permit a transfer that is not for consideration and (b) the transferee has agreed in writing to be bound by the same terms described in this letter to the extent and for the duration that such terms remain in effect at the time of the transfer.

The undersigned hereby acknowledges that the Company has agreed in the Underwriting Agreement to provide written notice of any event that would result in an extension of the Lock-Up Period pursuant to the previous paragraph to the undersigned (in accordance with Section 13 of the Underwriting Agreement) and agrees that any such notice properly delivered will be deemed to have been given to, and received by, the undersigned. The undersigned hereby further agrees that, prior to engaging in any transaction or taking any other action that is subject to the terms of this Lock-Up Agreement during the period from the date of this Lock-Up Agreement to and including the 34th day following the expiration of the initial Lock-Up Period, it will give notice thereof to the Company and will not consummate such transaction or take any such action unless it has received written confirmation from the Company that the Lock-Up Period (as such may have been extended pursuant to the previous paragraph) has expired.

Notwithstanding the foregoing, the undersigned may transfer the Undersigned’s Shares (i) as a bona fide gift or gifts, provided that the donee or donees thereof agree to be bound in writing by the restrictions set forth herein, (ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, provided that the trustee of the trust agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, (iii) with the prior written consent of the Representatives on behalf of the Underwriters or (iv) in response to a bona fide third party take-over bid made to all holders of shares of Common Stock or any other acquisition transaction whereby all or substantially all of the shares of Common Stock are acquired by a bona fide third party. For purposes of this Lock-Up Agreement, “immediate family” shall mean any relationship

¹	To be number of days required for expiration of lock-up to match expiration of IPO lock-up.

A-6

by blood, marriage or adoption, not more remote than first cousin. In addition, notwithstanding the foregoing, if the undersigned is a corporation, limited partnership, limited liability company or other entity, the undersigned may transfer the Undersigned’s Shares to its partners, members, stockholders or other affiliates, or any wholly owned subsidiary of the undersigned; provided, however, that in any such case, it shall be a condition to the transfer that the transferee execute an agreement stating that the transferee is receiving and holding such shares of Common Stock subject to the provisions of this Lock-Up Agreement and there shall be no further transfer of such shares of Common Stock except in accordance with this Lock-Up Agreement, and provided further that any such transfer shall not involve a disposition for value and no filing under Section 16(a) of the Securities Exchange Act of 1934, as amended, shall be required or shall be voluntarily made in connection with such transfer during the Lock-Up Period other than in connection with any such transfer to a partner, member, stockholder, subsidiary or other affiliate of the undersigned for which a filing under Section 16(a) of the Securities Exchange Act of 1934, as amended, may be made so long as such filing states in a footnote that (x) the reduction in beneficial ownership of the undersigned disclosed therein is the result of a transfer to the undersigned’s partner, member, stockholder, subsidiary or other affiliate, as applicable, and (y) all transferees thereof have entered into a lock-up agreement on substantially the same terms as this Lock-Up Agreement. The undersigned now has, and, except as contemplated by the Underwriting Agreement and clause (i), (ii), (iii) or (iv) above, for the duration of this Lock-Up Agreement will have, good and marketable title to the Undersigned’s Shares, free and clear of all liens, encumbrances, and claims whatsoever. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the Undersigned’s Shares except in compliance with the foregoing restrictions.

Furthermore, the undersigned may sell shares of Common Stock purchased by the undersigned in open market transactions following the completion of the Public Offering, provided that no filing under Section 16(a) of the Securities Exchange Act of 1934, as amended, shall be required or shall be voluntarily made in connection with such transfer during the Lock-Up Period.

The undersigned understands that, if (i) the Underwriting Agreement has not yet been executed and the Company withdraws the Registration Statement or (ii) the Underwriting Agreement has been executed and the Underwriting Agreement (other than the provisions thereof which survive termination) is terminated prior to payment for and delivery of the Shares to be sold thereunder, then, in each case, the undersigned shall be released from all obligations under this Lock-Up Agreement.

The undersigned understands that the Company and the Underwriters are relying upon this Lock-Up Agreement in proceeding toward consummation of the offering. The undersigned further understands that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors, and assigns.

In connection with the furnishing of this opinion, we have examined originals, or copies certified or otherwise identified to our satisfaction, of the following documents:

1. the Registration Statement;

2. the Pricing Prospectus;

3. the Prospectus;

4. the Underwriting Agreement; and

5. a specimen certificate for the Shares.

In addition, we have examined: (i) such corporate records of the Company as we have considered appropriate, including a copy of the certificate of incorporation, as amended and restated, and by-laws, as amended and restated, of the Company certified by the Company as in effect on the date hereof (collectively, the “Charter Documents”), including copies of resolutions of the board of directors of the Company relating to the transactions contemplated by the Underwriting Agreement, each certified by the Company; and (ii) such other certificates, agreements and documents as we deemed relevant and necessary as a basis for the opinions and beliefs expressed below.

In our examination of the documents referred to above, we have assumed, without independent investigation, the genuineness of all signatures, the legal capacity of all individuals who have executed any of the documents reviewed by us, the authenticity of all documents submitted to us as originals, the conformity to the originals of all documents submitted to us as certified, photostatic, reproduced or conformed copies of valid existing agreements or other documents, the authenticity of the latter documents and that the statements regarding matters of fact in the certificates, records, agreements, instruments and documents that we have examined are accurate and complete.

Based upon the above, and subject to the stated assumptions, exceptions and qualifications, we are of the opinion that:

1. The Company has been duly incorporated and is validly existing and in good standing under the laws of the State of Delaware. The Company has all necessary corporate power to execute, deliver and perform its obligations under the Underwriting Agreement and to own and hold its properties and conduct its business as described in the Registration Statement.

2. The Shares have been duly authorized by all necessary corporate action on the part of the Company, have been validly issued and are fully paid and non-assessable.

3. The Common Stock of the Company conforms in all material respects to the description contained in the Pricing Disclosure Package and the Prospectus under the caption “Description of Capital Stock.”

4. There are no preemptive or other similar rights to subscribe for or to purchase shares of Common Stock in the Company’s certificate of incorporation or by-laws, each as in effect on the date of this letter, or in any agreement, indenture or instrument listed as an Exhibit to the Registration Statement, or under the General Corporation Law of the State of Delaware (the “GCL”).

5. The Underwriting Agreement has been duly authorized, executed and delivered by the Company.

6. The statements in the Pricing Disclosure Package and the Prospectus under the heading “Material United States Federal Income Tax Consequences for Non-U.S. Holders,” to the extent that they constitute summaries of United States federal law or regulation or legal conclusions, have been reviewed by us and fairly summarize the matters described under that heading in all material respects.

7. The Registration Statement and the Prospectus, as of their respective effective or issue times, appear on their face to be appropriately responsive in all material respects to the requirements of the Act and the rules and regulations of the Commission under the Act, except for the financial statements, financial statement schedules and other financial data included in or omitted from either of them as to which we express no opinion.

8. The sale of the Shares by the Selling Stockholder, the execution and delivery by the Company of the Underwriting Agreement and the performance by the Company of its obligations thereunder will not (i) result in a violation of the Charter Documents, (ii) breach or result in a default under any agreement, indenture or instrument listed as an Exhibit to the Registration Statement or (iii) violate the GCL and those laws, rules and regulations of the United States of America and the State of New York (“Applicable Law”), in each case which in our experience are normally applicable to the transactions of the type contemplated by the Underwriting Agreement or any judgment, order or decree of any New York or federal court or governmental authority binding upon the Company listed on Schedule I to this opinion, except in the case of clause (ii) above, we express no opinion with respect to any provision of any agreement, indenture or instrument listed as an Exhibit to the Registration Statement to the extent that an opinion with respect to such provision would require making any financial, accounting or mathematical calculation or determination, and in the case of clauses (ii) and (iii) above, where the breach, default or violation could not reasonably be expected to have a material adverse effect on the Company and its subsidiaries taken as a whole. For purposes of this letter, the term “Applicable Law” does not include federal securities laws (except for purposes of the opinion expressed in paragraph 9 below) or state securities

Ladies and Gentlemen:

We have acted as special counsel to Global Brass and Copper Holdings, Inc. (the “Company”) in connection with the Underwriting Agreement (the “Underwriting Agreement”), dated as of September [—], 2013, among the Underwriters named on Schedule I thereof (the “Underwriters”), for whom you are acting as representatives, Xxxxxx Holdings, LLC (the “Selling Stockholder”) and the Company, relating to the purchase today by the Underwriters of [5,000,000] shares of common stock, par value $0.01 per share (the “Shares”), of the Company. This letter is being furnished at the request of the Company in connection with the delivery of our opinion to

you of even date herewith (the “Opinion”) under the Underwriting Agreement. Capitalized terms used and not otherwise defined in this letter have the respective meanings given those terms in the Underwriting Agreement.

The Company has filed with the Securities and Exchange Commission (the “Commission”) a Registration Statement on Form S-1 (File No. 333-191100) under the Securities Act of 1933, as amended (the “Act”). The Registration Statement was filed on September 11, 2013, was amended on September [—], 2013 and, we are advised orally by the staff of the Commission, was declared effective by the Commission at [—] on September [—], 2013. In this letter, the Registration Statement at the time it became effective under the Act, including the information deemed to be part of the Registration Statement under Rule 430A under the Act, is referred to as the “Registration Statement”; the preliminary prospectus dated September [—], 2013 included in the Registration Statement is referred to as the “Pricing Prospectus”; the Pricing Prospectus, taken together with the price of the Shares to the public and the underwriting discount or commission, is referred to as the “Pricing Disclosure Package”; and the final prospectus dated September [—], 2013 included as part of the Registration Statement as filed as required by Rule 424(b) under the Act, is referred to as the “Prospectus.”

The primary purpose of our professional engagement was not to establish factual matters or financial, accounting or statistical information. In addition, many determinations involved in the preparation of the Registration Statement, Pricing Prospectus and the Prospectus are of a wholly or partially non-legal character or relate to legal matters outside the scope of this letter. Furthermore, the limitations inherent in the independent verification of factual matters and in the role of outside counsel are such that

A-19

Xxxxxxx, Sachs & Co.

Xxxxxx Xxxxxxx & Co. LLC

Page 3

we have not undertaken to independently verify, and cannot and do not assume responsibility for the accuracy, completeness or fairness of, the statements contained in the Registration Statement, the Pricing Prospectus or the Prospectus (other than as explicitly stated in paragraphs 3 and 6 of the Opinion).

In the course of acting as special counsel to the Company in connection with the offering of the Shares, we have participated in conferences and telephone conversations with officers and other representatives of the Company and the independent registered public accountants for the Company during which conferences and conversations the contents of the Registration Statement, the Pricing Prospectus, the Prospectus and related matters were discussed. Based upon such participation (and relying as to factual matters on officers, employees and other representatives of the Company and its subsidiaries), our understanding of the U.S. federal securities laws and the experience we have gained in our practice thereunder, we hereby advise you that our work in connection with this matter did not disclose any information that caused us to believe that (i) at the time it became effective, the Registration Statement or any amendment thereto prior to the First Time of Delivery (except for the financial statements, financial statement schedules and other financial or accounting data included or omitted therefrom, as to which we express no such belief), included an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading; (ii) as of the Applicable Time, the Pricing Disclosure Package (except for the financial statements, financial statement schedules and other financial or accounting data included or omitted therefrom as to which we express no such belief) included an untrue statement of a material fact or

omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (iii) at the time the Prospectus was issued, at the time any amended or supplemented prospectus was issued or at the First Time of Delivery, the Prospectus or any amendment or supplement thereto (except for the financial statements, financial statement schedules and other financial or accounting data included or omitted therefrom as to which we express no such belief) included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

Global Brass and Copper Holdings, Inc.

Ladies and Gentlemen:

We have acted as special counsel to Xxxxxx Holdings, LLC, a Delaware limited liability company (the “Selling Stockholder”) in connection with the underwriting agreement (the “Underwriting Agreement”), dated as of September [—], 2013 among the Underwriters named on Schedule I thereto (the “Underwriters”), for whom you are acting as representatives, Global Brass and Copper Holdings, Inc. (the “Company”) and the Selling Stockholder relating to sale by the Selling Stockholder today of [5,000,000] shares (the “Shares”) of common stock, par value $0.01 per share (the “Common Stock”),

of the Company. This opinion is being furnished at the request of the Selling Stockholder as contemplated by Section 8(d) of the Underwriting Agreement. Capitalized terms used and not otherwise defined in this letter have the respective meanings given those terms in the Underwriting Agreement.

In connection with the furnishing of this opinion, we have examined an original, or a copy certified or otherwise identified to our satisfaction, of the Underwriting Agreement.

In addition, we have examined: (i) such limited liability company records of the Selling Stockholder as we have considered appropriate, including a copy of the certificate of formation and operating agreement, each as amended, of the Selling Stockholder, certified by the Selling Stockholder as in effect on the date of this letter (collectively, the “Entity Documents”) and copies of resolutions of the members of the Selling Stockholder relating to the sale by it of shares of Common Stock pursuant to the Underwriting Agreement certified by it; and (ii) such other certificates, agreements and documents as we deemed relevant and necessary as a basis for the opinions and beliefs expressed below. We have also relied upon oral and written statements of officers and representatives of the Selling Stockholder as to factual matters, the factual matters contained in the representations and warranties of the Selling Stockholder made in the Underwriting Agreement and upon certificates of public officials and the Selling Stockholder. In respect of matters of fact as to the ownership of the Shares to be sold by the Selling Stockholder, we have relied solely upon certificates of the Selling Stockholder without any independent inquiry.

In our examination of the documents referred to above, we have assumed, without independent investigation, the genuineness of all signatures, the legal capacity of all individuals who have executed any of the documents reviewed by us, the authenticity of all documents submitted to us as originals, the conformity to the originals of all documents submitted to us as certified, photostatic or reproduced or conformed copies of valid existing agreements or other documents, the authenticity of the latter documents and that the statements regarding matters of fact in the certificates, records, agreements, instruments and documents that we have examined are accurate and complete.

We have also assumed, without independent investigation, that the Registration Statement has been declared effective by the Securities and Exchange Commission and remains effective as of the date of this letter.

Based on the above, and subject to the stated assumptions, exceptions and qualifications stated below, we are of the opinion that:

1. The Selling Stockholder has all necessary limited liability company power to execute, deliver and perform its obligations under the Underwriting Agreement and to sell, assign, transfer and deliver the Shares.

A-24

Xxxxxxx, Sachs & Co.

Xxxxxx Xxxxxxx & Co. LLC

Page 4

2. The Underwriting Agreement has been duly authorized by the Selling Stockholder and has been duly executed and delivered by or on behalf of the Selling Stockholder.

3. With respect to the Selling Stockholder, the sale of the Shares to be sold by the Selling Stockholder under the Underwriting Agreement and the compliance by the Selling Stockholder with all of the provisions of the Underwriting Agreement will not (i) violate the Selling Stockholder’s Entity Documents, (ii) breach or result in a default under any agreement, indenture or instrument listed as an Exhibit to the Registration Statement a) to which the Selling Stockholder is a party, b) by which the Selling Stockholder is bound or c) to which any of the property or assets of the Selling Stockholder is subject or (iii) violate those laws, rules and regulations of the United States of America, the State of New York and the Delaware Limited Liability Company Act (the “LLCA”) (collectively, “Applicable Law”), in each case which in our experience are normally applicable to the transactions of the type contemplated by the Underwriting Agreement or any judgment, order or decree of any New York or federal court or governmental authority binding upon the Selling Stockholder listed on Schedule I to this opinion, except in the case of clause (ii) above, we express no opinion with respect to any provision of any agreement, indenture or instrument listed as an Exhibit to the Registration Statement to the extent that an opinion with respect to such provision would require making any financial, accounting or mathematical calculation or determination,

A-25

and in the case of clauses (ii) and (iii) above, where the breach, default or violation could not reasonably be expected to have a material adverse effect on the Selling Stockholder’s ability to consummate the transactions contemplated by the Underwriting Agreement. For purposes of this letter, the term “Applicable Law” does not include federal securities laws (except for the purposes of the opinion expressed in paragraph 4 below) or state securities laws, other anti-fraud laws, or any law, rule or regulation that is applicable to the Selling Stockholder or the transactions contemplated by the Underwriting Agreement solely because such law, rule or regulation is part of a regulatory regime applicable to any party to the Underwriting Agreement or any of its affiliates due to the specific assets or business of such party or such affiliate.

4. With respect to the Selling Stockholder, no consent, approval, authorization or order of, or filing, registration or qualification with, any Governmental Authority, which has not been obtained, taken or made is required by the Selling Stockholder under any Applicable Law for the execution and delivery by the Selling Stockholder of the Underwriting Agreement or the performance by the Selling Stockholder of its obligations under the Underwriting Agreement in connection with the Shares to be sold by the Selling Stockholder thereunder, except for the filings (if any) by the Selling Stockholder with the Securities and Exchange Commission required pursuant to Section 13(d), Section 13(f) or Section 16 of the Securities Exchange Act of 1934, as amended. For purposes of this letter, the term “Governmental Authority” means any executive, legislative, judicial, administrative or regulatory body of, the State of New York, the State of Delaware or the United States of America.

5. Assuming each Underwriter acquires its interest in the Shares it has purchased from the Selling Stockholder under the Underwriting Agreement in good faith without notice of any “adverse claim” (within the meaning of Section 8-105 of the Uniform Commercial Code in effect in the State of New York in the date of this letter (the “NY-UCC”)) with respect to the Shares, each Underwriter that has purchased the Shares delivered on the date hereof to The Depository Trust Company (assuming The Depository Trust Company is a “clearing corporation” within the meaning of Section 8-102(a)(5) of the NY-UCC) or other “securities intermediary” (assuming such other securities intermediary is a securities intermediary within the meaning of Section 8-102(a)(14) of the NY-UCC) by making payment therefor as provided in the Underwriting Agreement, and that has had the Shares credited by book entry to the “securities account” or “securities accounts” (within the meaning of Section 8-501(a) of the NY-UCC, assuming that the “securities intermediary’s jurisdiction” (within the meaning of Section 8-110(e) of the NY-UCC) for the securities account or accounts is the State of New York) of such Underwriter maintained by The Depository Trust Company or such other securities intermediary will have acquired a “security entitlement” (within the meaning of Section 8-102(a)(17) of the NY-UCC) to such Shares purchased by such Underwriter and no action based on an “adverse claim” (within the meaning of Section 8-102(a)(1) and Section 8-502 of the NY-UCC) may be asserted against such Underwriter with respect to such Shares.
