(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 Stockholders 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, 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 Stockholders 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 Stockholders on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company and the Selling Stockholders 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 Stockholders on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, each of the Selling Stockholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (e) were determined bypro 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), no

37

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. 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 Stockholders under this Section 9 shall be in addition to any liability which the Company and the Selling Stockholders may otherwise have and shall extend, upon the same terms and conditions, to each employee, officer and director of each Underwriter and each person, if any, who controls any Underwriter within the meaning of the Act and each broker-dealer or other 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 (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the Company) and to each person, if any, who controls the Company or any Selling Stockholder within the meaning of the Act.

(g) Each of PNC Capital Markets LLC, BTIG, LLC, KeyBanc Capital Markets Inc., Stifel, Nicolaus & Company, Incorporated and William Blair & Company, LLC (collectively, the“Non-Canadian Underwriters” and each, a“Non-Canadian Underwriter”) will only offer and sell Shares outside of Canada and will not, directly or indirectly, solicit offers to purchase or sell Shares in Canada. Provided that suchNon-Canadian Underwriter has not terminated and cancelled its obligations to the Company in accordance with this Agreement, suchNon-Canadian Underwriter agrees that, if any losses, claims, damages or liabilities, joint or several (collectively, “Claims”), are suffered by an indemnified party as contemplated in this Section 9 (and such Claims did not include suchNon-Canadian Underwriter on the basis that suchNon-Canadian Underwriter did not sign the underwriters’ certificate to the Canadian Prospectus or the Canadian Supplemented Prospectus) under Section 130 of the Securities Act (Ontario) or the equivalent provisions of Canadian Securities Laws in other Canadian Qualifying Jurisdictions based upon a misrepresentation or alleged misrepresentation (as defined in Canadian Securities Laws) in the Canadian Prospectus or Canadian Supplemented Prospectus, and such indemnified party is determined by a court of competent jurisdiction or other governmental authority in a final judgment or decision from which no appeal can be made to be liable pursuant to such laws in respect of such Claims and such indemnified party does pay such Claims (the “Liability Amount”), then suchNon-Canadian Underwriter shall indemnify on a several basis, and not a joint or joint and several basis, such indemnified party from and against the Liability Amount for suchNon-Canadian

38

Underwriter’s pro rata share of such Liability Amount, on the basis of and assuming that suchNon-Canadian Underwriter had signed the underwriters’ certificate to the Canadian Prospectus or the Canadian Supplemented Prospectus, but only to the extent of its underwriting obligation under Schedule I hereto. EachNon-Canadian Underwriter shall further indemnify such indemnified party, without regard to the final outcome of any such Claims, for suchNon-Canadian Underwriter’s pro rata share of any legal and other expenses reasonably incurred and paid by such indemnified party in connection with the investigation or defense of any such Claims (the “Indemnified Expenses”). For the purposes of determining the aggregate amount that the applicableNon-Canadian Underwriter is obligated to indemnify all other indemnified parties, “pro rata” will be based on the percentage of Firm Shares set forth opposite the name of suchNon-Canadian Underwriter in Schedule I hereto as compared to the total number of Firm Shares. For the avoidance of doubt, the maximum aggregate amount which aNon-Canadian Underwriter is required to indemnify the other indemnified parties under this Section 9(g) shall be the lesser of (i) the percentage of the total of the Liability Amount and Indemnified Expenses equal to the percentage of Firm Shares set forth opposite suchNon-Canadian Underwriter’s name in Schedule 1 hereto as compared to the total number of Firm Shares, and (ii) the total public offering price of the Firm Shares and Optional Shares suchNon-Canadian Underwriter is required to place or purchase under Schedule I hereto. The amount payable by aNon-Canadian Underwriter to the indemnified parties pursuant to this Section 9(g) shall be reduced to the extent that suchNon-Canadian Underwriter is required to pay damages directly to plaintiffs under Canadian Securities Laws in connection with the Claim or Claims that are the subject matter of the indemnification being sought. Further, aNon-Canadian Underwriter will only be required to make payment to an indemnified party pursuant to this Section 9(g) if (i) such indemnified party has used reasonable commercial efforts to be reimbursed for the Liability Amount and Indemnified Expenses pursuant to this Section 9 but has not been fully reimbursed and (ii) it has not been determined (either by a court of competent jurisdiction in a final judgment from which no appeal can be made or by acknowledgement of the indemnified party) that the Claim resulting in the Liability Amount and Indemnified Expenses was caused by or resulted from the fraud, fraudulent misrepresentation, gross negligence or willful misconduct of such indemnified party and to the extent that a court of competent jurisdiction in a final judgment from which no appeal can be made determines, or the indemnified party acknowledges, that such Claim to which such indemnified party is subject was caused by or resulted from the fraud, fraudulent misrepresentation, gross negligence or willful misconduct of such indemnified party then such indemnified party shall promptly reimburse to suchNon-Canadian Underwriter any Indemnified Expenses. If any Claim is asserted against any indemnified party that is or may be subject to indemnification under this Section 9(g), the indemnified party will notify theNon-Canadian Underwriters in writing as soon as possible of the particulars of such Claim (but the omission so to notify theNon-Canadian Underwriters of any potential Claim shall not relieve aNon-Canadian Underwriter from any liability which it may

39

have to any indemnified party and any omission so to notify theNon-Canadian Underwriters of any actual Claim shall affect aNon-Canadian Underwriter’s liability only to the extent that suchNon-Canadian Underwriter is actually and materially prejudiced by that failure). EachNon-Canadian Underwriter agrees that to the extent that suchNon-Canadian Underwriter is not a party to such Claim the other Underwriters will be entitled to conduct the defence of any such action or proceeding brought to enforce such Claim, such theNon-Canadian Underwriter’s liability hereunder shall not be reduced in any way based upon the conduct of such defense unless the indemnified parties are determined to be grossly negligent (by a court of competent jurisdiction in a final judgment from which no appeal can be made) in conducting such defence. The Underwriters shall provide theNon-Canadian Underwriters with notice of any material developments in the action or proceeding.

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 withinthirty-six hours after such default by any Underwriter you do not arrange for the purchase of such Shares, then the Company and the Selling Stockholders shall be entitled to a further period ofthirty-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 Company and the Selling Stockholders that you have so arranged for the purchase of such Shares, or the Company or a Selling Stockholder notifies you that it has so arranged for the purchase of such Shares, you or the Company or the Selling Stockholders shall have the right to postpone such 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 Prospectuses, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectuses 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, the Company and the Selling Stockholders as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased does not exceedone-eleventh of the aggregate number of all the Shares to be purchased at such Time of Delivery, then the Company and the Selling Stockholders shall have the right to require eachnon-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 eachnon-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.

40

(c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you, the Company and the Selling Stockholders as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased exceedsone-eleventh of the aggregate number of all the Shares to be purchased at such Time of Delivery, or if the Company and the Selling Stockholders shall not exercise the right described in subsection (b) above to requirenon-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 Stockholders to sell the Optional Shares) shall thereupon terminate, without liability on the part of anynon-defaulting Underwriter, the Company or the Selling Stockholders, except for the expenses to be borne by the Company, the Selling Stockholders 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 Stockholders 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, any Selling Stockholder, or any officer or director or controlling person of the Company or any controlling person of any 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 Stockholders 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 Company and the Selling Stockholders as provided herein (other than as set forth in clauses (i), (iii), (iv) or (v) of Section 8(k)), the Company will reimburse the Underwriters through the Representatives for allout-of-pocket expenses approved in writing by the Representatives, 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 Stockholders shall then be under no further liability to any Underwriter except as provided in Sections 7 and 9 hereof.

13. In all dealings hereunder, the Representatives 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; and in all dealings with any Selling Stockholder hereunder, you and the Company shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of such Selling Stockholder made or given by any or all of theAttorneys-in-Fact for such Selling Stockholder.

42

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 any Selling Stockholder, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Company or any 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 any Selling Stockholder on other matters) or any other obligation to the Company or any Selling Stockholder except the obligations expressly set forth in this Agreement and (iv) the Company and each Selling Stockholder has consulted its own legal and financial advisors to the extent it deemed appropriate. The Company and each Selling Stockholder agrees that it will not claim that the Underwriters, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company or any Selling Stockholder, in connection with such transaction or the process leading thereto.

As representatives (the “Representatives”) of the several Underwriters

named in Schedule I to the Underwriting Agreement

Re: Zekelman Industries, Inc. –Lock-Up Agreement

Ladies and Gentlemen:

The undersigned understands that you, as Representatives (the “Representative”), propose to enter into an underwriting agreement (the “Underwriting Agreement”) on behalf of the several Underwriters named inSchedule I to such agreement (collectively, the “Underwriters”), with Zekelman Industries, Inc., a Delaware corporation (the “Company”), and the Selling Stockholders named inSchedule II to such agreement, providing for a public offering (the “Public Offering”) of Class A Subordinate Voting Stock, par value $0.01 per share (the “Stock”), of the Company (the “Shares”) pursuant to a Registration Statement on FormS-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 beginning from the date of this agreement (this“Lock-Up Agreement”) and continuing to and including the date 365 days after the date set forth on the final prospectus used to sell the Shares (the “StockholderLock-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 Stock, or any options or warrants to purchase any shares of Stock, or any securities convertible into, exchangeable for or

that represent the right to receive shares of Stock, 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.

[If the undersigned is an officer or director of the Company, (1) the undersigned further agrees that the foregoing restrictions shall be equally applicable to any issuer-directed Shares the undersigned may purchase in the offering, (2) Goldman Sachs & Co. LLC agrees 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 Stock, Goldman Sachs & Co. LLC will notify the Company of the impending release or waiver, and (3) the Company has agreed in Section 5(g)(ii) of the 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. Any release or waiver granted by Goldman Sachs & Co. LLC 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 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.]

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) solely to the extent such options, warrants or other equity awards expire during the StockholderLock-Up Period, the transfer of Stock or of any securities convertible into Stock to the Company upon a vesting event of the Company’s securities or upon the exercise of options, warrants or other equity awards to purchase the Company’s securities on a “cashless” or “net exercise” basis, to the extent permitted by the instruments representing such options, warrants or other equity awards (whether to cover the applicable exercise price, withholding tax obligations or otherwise), and the Company’s cancellation of all or a portion thereof to pay the exercise price and/or withholding tax obligations, (iv) the establishment of a trading plan pursuant to Rule10b5-1 under the Exchange Act for the transfer of Stock, provided that (A) such plan does not provide for the transfer of Stock during the StockholderLock-Up Period, and (B) the establishment of such plan does not require or otherwise result in any public filing or other public announcement of such plan during the StockholderLock-Up Period, (v) the transfer of Stock or any security convertible into or exercisable or exchangeable for Stock that occurs by operation of law pursuant to a qualified domestic order in connection with a divorce settlement or other court order, provided in

the case of this clause (v) that the transferee of such shares agrees to be bound in writing to the restrictions set forth in thisLock-Up Agreement, (vi) the transfer of Stock or any security convertible into or exercisable or exchangeable for Stock after the completion of the Public Offering pursuant to a bona fide third-party tender offer, merger, consolidation or other similar transaction that is approved by the Board of Directors of the Company, made to all holders of Stock involving a Change of Control (as defined below), provided that in the event that the tender offer, merger, consolidation or other such transaction is not completed, the Stock owned by the undersigned shall remain subject to the restrictions contained in this letter, or (vii) with the prior written consent of Goldman Sachs & Co. LLC on behalf of the Underwriters. For purposes of thisLock-Up Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin and “Change of Control” shall mean the transfer (whether by tender offer, merger, consolidation or other similar transaction), in one transaction or a series of related transactions, to a person or group of affiliated persons (other than an Underwriter pursuant to the Public Offering), of the Company’s voting securities if, after such transfer, such person or group of affiliated persons would hold more than 90% of the voting control of the outstanding voting securities of the Company (or the surviving entity).

In addition, notwithstanding the foregoing, if the undersigned is a corporation, the corporation may transfer the capital stock of the Company to any wholly-owned subsidiary of such corporation; 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 capital stock subject to the provisions of thisLock-Up Agreement and there shall be no further transfer of such capital stock except in accordance with thisLock-Up Agreement, and provided further that any such transfer shall not involve a disposition for value. The undersigned now has, and, except as contemplated by clause (i), (ii), or (iii) above, for the duration of thisLock-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.

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