Castle Parties, at the aggregate Purchase Price therefor, up to such Non-Defaulting Commitment Party’s Adjusted Commitment Percentage of all New Money Notes required to be purchased by the Defaulting Commitment Party pursuant to Section 2.1 but with respect to which such Defaulting Commitment Party did not make the required deposit in accordance with Section

EX-11-

2.3. Within one Business Day after a Funding Default, the A.M. Castle Parties shall send a written notice to each Non-Defaulting Commitment Party specifying (x) the aggregate principal amount of New Money Notes subject to such Funding Default (collectively, the “Default Notes”) and (y) the maximum principal amount of Default Notes such Non-Defaulting Commitment Party may elect to commit to purchase (determined in accordance with the first sentence of this Section 2.4(a)).

(b) Each Non-Defaulting Commitment Party will have three Business Days after receipt of such notice to elect to exercise its Default Purchase Right by notifying the A.M. Castle Parties in writing of its election and specifying the maximum principal amount of Default Notes that it is committing to purchase (up to the maximum principal amount of Default Notes such Non-Defaulting Commitment Party is permitted to commit to purchase pursuant to the first sentence of Section 2.4(a)).

(c) If any Non-Defaulting Commitment Party elects to commit to purchase less than the maximum principal amount of Default Notes such Non-Defaulting Commitment Party is permitted to commit to purchase pursuant to the first sentence of Section 2.4(a) or if any Non-Defaulting Commitment Party does not elect to commit to purchase any Default Notes within the three-Business Day period referred to in the immediately preceding sentence, then the principal amount of Default Notes that such Non-Defaulting Commitment Party does not commit to purchase shall be allocated among all of the Non-Defaulting Commitment Parties who (in addition to exercising in full their respective Default Purchase Rights) elect to commit to purchase such principal amount of Default Notes on a pro rata basis based on the respective Adjusted Commitment Percentages of such Non-Defaulting Commitment Parties (such allocation and commitment to purchase to be made by utilizing the same procedures set forth in the two immediately preceding sentences).

(d) If Non-Defaulting Commitment Parties elect to commit to purchase all (but not less than all) Default Notes in accordance with Section 2.4(a), each Non-Defaulting Commitment Party that has elected to commit to purchase Default Notes hereby agrees, severally and not jointly, to deposit into the Escrow Account pursuant to the Escrow Agreement, by wire transfer of immediately available funds, an amount equal to the aggregate Purchase Price for such Default Notes no later than one Business Day after the day that the A.M. Castle Parties have notified the Non-Defaulting Commitment Parties that Non-Defaulting Commitment Parties have elected to purchase all (but not less than all) Default Notes.

(e) If Non-Defaulting Commitment Parties do not elect to commit to purchase all Default Notes in accordance with Section 2.4 or if any Non-Defaulting Commitment Party fails to deposit the aggregate Purchase Price for any Default Notes it has elected to purchase within the time set forth in Section 2.4(d) above, then (i) no Non-Defaulting Commitment Party shall be required to deposit in the Escrow Account any portion of the Purchase Price for the Default Notes which such Non-Defaulting Commitment Party may have elected to commit to purchase pursuant to Section 2.4, except as may otherwise be agreed to in writing by the Requisite Commitment Parties and the A.M. Castle Parties, and (ii) the A.M. Castle Parties shall be permitted to terminate this Agreement in accordance with Section 9.2(b) hereof. The Default Notes with respect to which each Commitment Party is required to deposit funds into the Escrow Account

pursuant to Section 2.4, if any, together with any New Money Notes required to be purchased by such Commitment Party in accordance with Section 2.1, shall be referred to as such Commitment Party’s “Purchased Notes”.

Section 2.5 Closing.

(a) Unless otherwise mutually agreed in writing by the A.M. Castle Parties and the Requisite Commitment Parties, the closing (the “Closing”) of the purchase and sale of New Money Notes and, if applicable, Default Notes hereunder will occur at 10:00 a.m., New York City time, on the date on which all of the conditions to closing contained in Article VIII hereof have been satisfied or otherwise waived in accordance with the terms of this Agreement (other than conditions that by their terms are to be satisfied at the Closing, but subject to the satisfaction or waiver of such conditions at such time) (the “Closing Date”). At the Closing, (i) the A.M.

Castle Parties shall not be permitted to terminate this Agreement and the transactions contemplated hereby pursuant to this Section 9.2(a) unless Non-Defaulting Commitment Parties do not elect to commit to purchase all of the Default Notes after the process for exercising Default Purchase Rights has been exhausted in accordance with Section 2.4(a);

(c) any of the conditions set forth in Section 8.2 hereof become incapable of fulfillment (other than through the failure of the A.M. Castle Parties to comply with their obligations) and the A.M. Castle Parties have not waived such conditions; or

EX-34-

(d) the obligations of the A.M. Castle Parties under the Restructuring Support Agreement are terminated in accordance with the terms of the Restructuring Support Agreement.

Section 9.3 Mutual Termination. This Agreement may be terminated at any time by written consent of the A.M. Castle Parties and the Requisite Commitment Parties.

Section 9.4 Effect of Termination.

(a) No Party may terminate this Agreement if such Party failed to perform or comply in all material respects with the terms and conditions of this Agreement, and such failure to perform or comply caused, or resulted in, the occurrence of one or more acts that would otherwise permit termination by such Party as are specified herein.

(b) In the event of a termination of this Agreement in accordance with Article IX at a time after all or any portion of the Purchase Price for the Purchased Notes has been deposited into the Escrow Account by any of the Commitment Parties, the Commitment Parties that have deposited such Purchase Price (or portion thereof) shall be entitled to the return of such amount. In such a case, the Commitment Parties and the A.M. Castle Parties hereby agree to execute and deliver to the Escrow Agent, promptly after the effective date of any such termination (but in any event no later than one Business Day after any such effective date), a letter instructing the Escrow Agent to pay to each applicable Commitment Party, by wire transfer of immediately available funds to an account designated by such Commitment Party, the amount of Purchase Price that such Commitment Party is entitled to receive pursuant to this Section 9.4(b). If this Agreement is terminated for any reason, the A.M. Castle Parties shall, promptly after the date of such termination, pay the Put Option Payment to the Commitment Parties or their designees in accordance with Section 3.1.

(c) In the event of a termination of this Agreement in accordance with this Article IX, the provisions of this Agreement shall immediately become void and of no further force or effect (other than Article I, Article III, Article IX, Article X, Article XII, and Article XIII hereof (and any defined terms used in any such Section or Articles), and other than in respect of any liability of any party for any breach of this Agreement prior to such termination, which shall in each case expressly survive any such termination).

ARTICLE X INDEMNIFICATION

Section 10.1 Indemnification Obligations. Whether or not any of the Contemplated Transactions are consummated, the A.M. Castle Parties hereby agree, jointly and severally, to indemnify and hold harmless each of the Commitment Parties and each of their respective Affiliates, Related Funds, stockholders, equity holders, members, partners, managers, officers, directors, employees, attorneys, accountants, financial advisors, consultants, agents, advisors and controlling persons (each, in such capacity, an “Indemnified Party”) from and against any and all losses, claims, damages, liabilities and expenses, joint or several, imposed on, sustained,

EX-35-

incurred or suffered by, or asserted against, any Indemnified Party as a result of or arising out of or related to, directly or indirectly, this Agreement, any of the transactions contemplated by this Agreement (including any claims arising from, related to or in connection with, any violations or alleged violations of U.S. federal or other securities laws), or any of the other Contemplated Transactions, or any breach by the A.M. Castle Parties of any of their representations, warranties and/or covenants set forth in this Agreement, or any claim, litigation, investigation or other Proceeding relating to or arising out of any of the foregoing, regardless of whether any such Indemnified Party is a party thereto, and to reimburse each such Indemnified Party for the reasonable legal or other out-of-pocket costs and expenses as they are incurred in connection with investigating, monitoring, responding to or defending any of the foregoing (collectively, “Losses”); provided, that the foregoing indemnification will not, as to any Indemnified Party, apply to Losses that are (%3) caused by a Funding Default of such Indemnified Party, or (%3) to the extent they are determined by a final, non-appealable decision by a court of competent jurisdiction to arise from the bad faith, gross negligence, willful misconduct or breach by such Indemnified Party of its obligations under this Agreement or the Restructuring Support Agreement (clauses (a) and (b), the “Loss Exceptions”). If for any reason the foregoing indemnification is unavailable to any Indemnified Party or insufficient to hold it harmless, then the A.M. Castle Parties shall contribute to the amount paid or payable by such Indemnified Party as a result of such Loss in such proportion as is appropriate to reflect not only the relative benefits received by the A.M. Castle Parties on the one hand and such Indemnified Party on the other hand but also the relative fault of any A.M. Castle Party, on the one hand, and such Indemnified Party, on the other hand, as well as any relevant equitable considerations. It is hereby agreed that the relative benefits to the Indemnifying Party, on the one hand, and all Indemnified Parties, on the other hand, shall be deemed to be in the same proportion as (a) the total value received or proposed to be received by the A.M. Castle Parties pursuant to the issuance and sale of the New Money Notes as contemplated by this Agreement bears to (b) the Put Option Payment paid or proposed to be paid to the Commitment Parties (applying a liquidity discount as appropriate). The A.M. Castle Parties also agree that no Indemnified Party shall have any liability based on its exclusive or contributory negligence or otherwise to the A.M. Castle Parties, any Person asserting claims on behalf of or in right of the A.M. Castle Parties, or any other Person in connection with or as a result of this Agreement, the Definitive Documents or the transactions contemplated hereby or thereby or any of the Contemplated Transactions, except as to any Indemnified Party to the extent that Loss incurred by the A.M. Castle Parties resulted from the Loss Exceptions. The terms set forth in this Article X shall survive termination of this Agreement and shall remain in full force and effect regardless of whether the transactions contemplated by this Agreement are consummated. The indemnity and reimbursement obligations of the A.M. Castle Parties under Article X are in addition to, and do not limit, the A.M. Castle Parties’ obligations under Article III hereof.

Section 10.2 Indemnification Procedures. Promptly after receipt by an Indemnified Party of notice of the commencement of any claim, challenge, litigation, investigation or other Proceeding which might give rise to indemnification hereunder (an “Indemnified Claim”) by any Person, such Indemnified Person will, if a claim is to be made hereunder against the A.M. Castle Parties (referred to for purposes of this Article X as the “Indemnifying Party”) in respect thereof, notify promptly the Indemnifying Party in writing of the commencement thereof; provided, that the omission or delay to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability that it may have hereunder. In case any such Indemnified Claims are brought

EX-36-

against any Indemnified Party and such Indemnified Party notifies the Indemnifying Party of the commencement thereof, the Indemnifying Party will be entitled to participate therein at its sole cost and expense (but the Indemnified Party shall control the defense of such Indemnified Claim if the Indemnifying Party does not have the right to assume, or does not timely assume, the defense thereof in accordance with this Article X), and, to the extent that such Indemnifying Party may elect by written notice delivered to such Indemnified Party no later than thirty days after receipt of notice of the Indemnified Claim (but in any event at least ten days before a response to such Indemnified Claim is due), to assume the defense thereof (with counsel reasonably satisfactory to the Indemnified Party); provided, that the Indemnifying Party shall not have the right to assume the defense of any Indemnified Claim unless (a) the Indemnifying Party shall have expressly agreed in writing that, as between the Indemnifying Party and the Indemnified Party, the Indemnifying Party shall be solely obligated, subject in all respects to the Loss Exceptions, to satisfy and discharge such Indemnified Claim, (b) such Indemnified Claim involves only money damages and does not seek an injunction or other equitable relief against the Indemnified Party, (c) the Indemnified Party has not been advised by counsel that an actual or potential conflict exists between the Indemnified Party and the Indemnifying Party in connection with the defense of the Indemnified Claim or that there are legal or other defenses available to an Indemnified Party that are different from or inconsistent with those available to an Indemnifying Party, and (d) the Indemnified Claim does not relate to or otherwise arise in connection with any criminal or regulatory enforcement action or a tax proceeding to which an Indemnified Party is a party. Upon receipt of notice from the Indemnifying Party to such Indemnified Party of its election to so assume the defense of such Indemnified Claims, the Indemnifying Party shall not be liable to such Indemnified Party for expenses incurred by such Indemnified Party after the date of the receipt of such notice in connection with the defense thereof (other than reasonable costs of investigation) unless (x) the Indemnifying Party is not permitted to assume the defense of such Indemnified Claims in accordance with the proviso to the immediately preceding sentence, (y) the Indemnifying Party shall have failed or is failing to diligently defend such Indemnified Claim, and is provided written notice of such failure by the Indemnified Party, or (z) the Indemnifying Party shall have authorized in writing the employment of counsel for such Indemnified Party. If the Indemnifying Party assumes (and has a right to assume) the defense of an Indemnified Claim in accordance with this Article X, the Indemnified Party shall be permitted to participate in any such defense at its own expense. All amounts paid by the Indemnifying Party to an Indemnified Person under this Article X shall, to the extent permitted by applicable Law, be treated as adjustments to the purchase price for the Purchased Notes for all applicable tax purposes.

Section 10.3 Settlement of Indemnified Claims. The Indemnifying Party shall not, without the prior written consent of an Indemnified Party, effect any settlement of any pending or threatened Indemnified Claims in respect of which indemnity or contribution has been sought hereunder by such Indemnified Party unless such settlement (x) includes an unconditional release of such Indemnified Party in form and substance reasonably satisfactory to such Indemnified Party from all liability on the claims that are the subject matter of such Indemnified Claims, (y) provides for the payment by the Indemnifying Party of money as sole relief for the claimant, and (z) does not include any statement as to, or any finding or admission of, any fault, culpability or a failure to act by or on behalf of any Indemnified Party. Notwithstanding anything in this Article X to the contrary, if at any time an Indemnified Party shall have requested the Indemnifying Party to reimburse such Indemnified Party for legal or other expenses in connection with investigating,

EX-37-

responding to or defending any Indemnified Claims as contemplated by this Article X, the Indemnifying Party shall be liable for any settlement, compromise, consent to the entry of any judgment or judgment with respect to any Indemnified Claims effected without its written consent if (i) such settlement, compromise or consent is entered into more than 45 days after receipt by the Indemnifying Party of such request for reimbursement and (ii) the Indemnifying Party shall not have reimbursed such Indemnified Party in accordance with such request prior to the date of such settlement, compromise or consent.

ARTICLE XI
SURVIVAL OF REPRESENTATIONS, WARRANTIES AND AGREEMENTS

No representations, warranties, covenants or agreements made in this Agreement shall survive after the Closing except for covenants and agreements that by their terms are to be satisfied after the Closing, which covenants and agreements shall survive until satisfied in accordance with their terms.

ARTICLE XII
AMENDMENTS AND WAIVERS

Any term of this Agreement may be amended or modified and the compliance with any term of this Agreement may be waived (either generally or in a particular instance, and either retroactively or prospectively) only if such amendment, modification or waiver is signed, in the case of an amendment or modification, by the Requisite Commitment Parties and the A.M. Castle Parties, or in the case of a waiver, by the Requisite Commitment Parties (if compliance by the A.M. Castle Parties is being waived) or by the A.M. Castle Parties (if compliance by any of the Commitment Parties is being waived); provided, however, that (a)  Schedule 1 hereto may be amended in accordance with the terms of Section 14.1; (b) any amendment or modification to this Agreement that would have the effect of changing the Commitment Percentage of any Commitment Party shall require the prior written consent of such Commitment Party unless otherwise expressly contemplated by this Agreement, (c) any amendment or modification to (i) the definition of “Purchase Price,” and (ii) the allocation of the Put Option Payment among the Commitment Parties as set forth in Section 3.1 shall require the prior written consent of each Commitment Party adversely affected thereby, and (d) any amendment, modification or waiver to this Agreement that would materially adversely affect the rights or increase the obligations of any Commitment Party under this Agreement in a manner that is disproportionate in any material respect to the comparable rights and obligations of the Requisite Commitment Parties under this Agreement shall require the prior written consent of such Commitment Party. No delay on the part of any party in exercising any right, power or privilege pursuant to this Agreement will operate as a waiver thereof, nor will any waiver on the part of any party of any right, power or privilege pursuant to this Agreement, or any single or partial exercise of any right, power or privilege pursuant to this Agreement, preclude any other or further exercise thereof or the exercise of any other right, power or privilege pursuant to this Agreement. The rights and remedies provided pursuant to this Agreement are cumulative and are not exclusive of any rights or remedies which any party otherwise may have at law or in equity.

ARTICLE XIV
MISCELLANEOUS

Section 14.1 Assignments. This Agreement shall inure to the benefit of and be binding upon the Parties and their respective successors and permitted assigns. Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned by any of the Parties (whether by operation of Law or otherwise) without the prior written consent of the A.M. Castle Parties and the Requisite Commitment Parties. Notwithstanding the immediately preceding sentence, any Commitment Party’s rights, obligations or interests hereunder may be freely assigned, delegated or transferred, in whole or in part, by such Commitment Party, to (%3) any other Commitment Party, (%3) any Affiliate of a Commitment Party, (%3) any Related Fund of a Commitment Party or (%3) any other Person not referred to in clause (a), clause (b) or clause (c) above so long as such Person is approved in writing by the Requisite Commitment Parties prior to such assignment, delegation or transfer (for purposes of this clause (d), the Commitment Party proposing to make such assignment, delegation or transfer, and all of its Affiliates and Related Funds, shall be deemed to a be Defaulting Commitment Party for purposes of the definition of “Requisite Commitment Parties”); provided, that (x) any such assignee assumes the obligations of the assigning Commitment Party hereunder and agrees in writing prior to such assignment to be bound by the terms hereof in the same manner as the assigning Commitment Party, (y) any assignee of a Commitment must be an Accredited Investor and (z) no Commitment Party shall be permitted to assign its Commitment except in connection with a transfer of First Lien Secured Debt Claims permitted by the Restructuring Support Agreement. Following any assignment described in the immediately preceding sentence, Schedule 1 hereto shall be updated by the A.M. Castle Parties (in consultation with the assigning Commitment Party and the assignee) solely to reflect the name and address of the applicable assignee or assignees and the Commitment Percentage that shall apply to such assignee or assignees, and any changes to the Commitment Percentage applicable to the assigning Commitment Party. Any update to Schedule 1 hereto described in the immediately preceding sentence shall not be deemed an amendment to this Agreement. Notwithstanding the foregoing or any other provisions herein, unless otherwise agreed in any instance by the A.M. Castle Parties and the other Commitment Parties, no such assignment will relieve the assigning Commitment Party of its obligations hereunder with respect to its Commitment if any such assignee fails to perform such obligations.

Section 14.2 Severability. If any provision of this Agreement or the application of any such provision to any Person or circumstance shall be held invalid or unenforceable in whole or in part, such invalidity or unenforceability shall attach only to such provision or part thereof and the remaining part of such provision hereof and this Agreement shall continue in full force and effect. Upon any such determination of invalidity, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible, in a reasonably acceptable manner, such that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.

Section 14.3 Entire Agreement; Prior Negotiations. This Agreement, including the schedules and exhibits attached hereto, together with the Restructuring Support Agreement and

EX-40-

the Plan, constitutes the entire agreement of the Parties with respect to the subject matter hereof and supersedes all prior agreements (oral or written), negotiations, and documents between and among the Parties (and their respective advisors) with respect to the subject matter hereof and thereof, except for any confidentiality agreements heretofore executed between or among any of the Parties, which shall continue in full force and effect subject to the terms thereof.

Section 14.4 Counterparts. This Agreement may be executed in several counterparts, each of which shall be deemed to be an original, and all of which together shall be deemed to be one and the same agreement. Execution copies of this Agreement and executed counterpart signature pages hereto may be delivered by electronic mail (in “.pdf” or “.tif” format), facsimile or other electronic imaging means, which shall be deemed to be an original for the purposes of this Agreement.

Section 14.5 Governing Law. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO ANY CONFLICTS OF LAW PROVISIONS WHICH WOULD REQUIRE THE APPLICATION OF THE LAW OF ANY OTHER JURISDICTION.

Section 14.6 Consent to Jurisdiction. Each of the Parties hereby irrevocably and unconditionally submits to the exclusive jurisdiction of any state or federal court located in the State and County of New York in any action or proceeding arising out of or relating to this Agreement, or for recognition or enforcement of any judgment arising therefrom, and further irrevocably and unconditionally agrees that all claims arising out of or relating to this Agreement brought by them shall be brought, and shall be heard and determined, exclusively in the aforementioned court. Each Party irrevocably waives any objection as to venue or inconvenient forum. Each Party agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Notwithstanding the foregoing consent to New York jurisdiction, if the Chapter 11 Cases are commenced by the A.M. Castle Parties, each Party agrees that the Bankruptcy Court shall have exclusive jurisdiction of all matters arising out of or in connection with this Agreement.

Section 14.7 Waiver of Trial by Jury. EACH PARTY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY PROCEEDING ARISING OUT OF OR RELATING IN ANY WAY TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

Section 14.8 Specific Performance. It is understood and agreed by the Parties that money damages would be an insufficient remedy for any breach of this Agreement by any Party and each non-breaching Party shall be entitled to seek specific performance and injunctive or other equitable relief, including reasonable attorneys’ fees, costs and expenses, as a remedy of any such breach without the necessity of proving the inadequacy of money damages as a remedy, in addition to any other remedy to which such non-breaching Party may be entitled at law or in equity; provided, however, that each Party agrees to waive any requirement for the securing or posting of a bond in connection with such remedy. The Parties agree that for so long as a Party has not taken any action to prejudice the enforceability of this Agreement (including alleging in any pleading that this

EX-41-

Agreement is unenforceable), and has taken such actions as are reasonably required or desirable for the enforcement hereof, then such Party shall have no liability for damages hereunder in the event any court of competent jurisdiction determines on a final and non-appealable basis that this Agreement is not enforceable.

Section 14.9 Further Assurances. From time to time after the Closing Date, the Parties will execute, acknowledge and deliver to the other Parties such other documents, instruments and certificates, and will take such other actions, as any other Party may reasonably request in order to consummate the transactions contemplated by this Agreement.

Section 14.10 Headings. The section headings, paragraphs and subsections of this Agreement are for convenience of reference only and shall not, for any purpose, be deemed a part of this Agreement and shall not affect the interpretation of this Agreement.

Section 14.11 Interpretation. This Agreement is the product of negotiations among the Parties, and the enforcement or interpretation of this Agreement is to be interpreted in a neutral manner. Any presumption with regard to interpretation for or against any Party by reason of that Party having drafted or caused to be drafted this Agreement or any portion of this Agreement, shall not be effective in regard to the interpretation of this Agreement.

Section 14.12 Several, Not Joint, Obligations. The representations, warranties, covenants and other obligations of the Commitment Parties under this Agreement are, in all respects, several and not joint or joint and several, such that no Commitment Party shall be liable or otherwise responsible for any representations, warranties, covenants or other obligations of any other Commitment Party, or any breach or violation thereof.

Section 14.13 Disclosure. Unless otherwise required by applicable Law, the A.M. Castle Parties will not, without each of the Commitment Parties’ prior written consent, disclose to any Person the Commitment Percentage of any Commitment Party, except for (a) disclosures to the A.M. Castle Parties’ representatives or advisors in connection with the transactions contemplated hereby and subject to their agreement to be bound by the confidentiality provisions hereof and (b) disclosures to parties to this Agreement solely for purposes of calculating the Adjusted Commitment Percentage of a Non-Defaulting Commitment Party.

Section 14.14 No Recourse Party. Notwithstanding anything that may be expressed or implied in this Agreement, and notwithstanding the fact that certain of the Commitment Parties may be partnerships or limited liability companies, the A.M. Castle Parties and the Commitment Parties covenant, agree and acknowledge that no recourse under this Agreement shall be had against any former, current or future directors, officers, agents, Affiliates, general or limited partners, members, managers, employees, stockholders or equity holders of any Commitment Party, or any former, current or future directors, officers, agents, Affiliates, employees, general or limited partners, members, managers, employees, stockholders or equity holders of any of the foregoing, as such (any such Person, a “No Recourse Party”), whether by the enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any statute, regulation or other applicable Law, it being expressly agreed and acknowledged that no liability whatsoever shall attach to, be imposed on or otherwise be incurred by any No Recourse Party for any obligation of any Commitment Party

EX-42-

under this Agreement for any claim based on, in respect of or by reason of such obligations or their creation; provided, that nothing in this Section 14.14 shall relieve the Commitment Parties of their obligations under this Agreement.

Section 14.15 Settlement Discussions. Except as expressly provided in this Agreement (as may be amended from time to time), the Definitive Documents or any confidentiality agreements executed between or among the Parties, nothing herein is intended to, or does, in any manner waive, limit, impair or restrict the ability of each of the Parties to (a) protect and preserve its rights, remedies and interests, including, without limitation, its claims against any of the other Parties (or their respective Affiliates or subsidiaries) and any liens or security interests it may have in any assets of the A.M. Castle Parties, (b) consult with any of the other Parties, (c) participate in any Chapter 11 Cases, or (d) purchase, sell or enter into any transactions in connection with the A.M. Castle Claims/Interests (as defined in the Restructuring Support Agreement), in each case subject to the terms of the Restructuring Support Agreement. Without limiting the foregoing sentence in any way, if the Restructuring is not consummated, or if this Agreement or the Restructuring Support Agreement is terminated for any reason, nothing shall be construed herein as a waiver by any Party of any or all of such Party’s rights, remedies, claims and defenses and the Parties expressly reserve any and all of their respective rights, remedies, claims and defenses. No Party shall have, by reason of this Agreement, a fiduciary relationship in respect of any other Party, any holder of A.M. Castle Claims/Interests (as defined in the Restructuring Support Agreement), or any other Person, and nothing in this Agreement or the Restructuring Support Agreement (including the Term Sheet and the other exhibits attached hereto and thereto), express or implied, is intended to impose, or shall be construed as imposing, upon any Party any obligations in respect of this Agreement, the Restructuring Support Agreement or the Restructuring except as expressly set forth herein or therein. This Agreement is part of a proposed settlement of matters that could otherwise be the subject of litigation among the Parties. Nothing herein (including the schedules and exhibits attached hereto) shall be construed as or be deemed to be evidence of an admission or concession of any kind on the part of any Party of any claim, fault, liability or damages whatsoever. Each of the Parties denies any and all wrongdoing or liability of any kind and does not concede any infirmity in the claims or defenses which it has asserted or could assert. Pursuant to Federal Rule of Evidence 408, any applicable state rules of evidence and any other applicable Law, foreign or domestic, this Agreement and all negotiations relating hereto shall not be admissible into evidence in any proceeding other than to prove the existence of this Agreement or in a proceeding to enforce the terms of this Agreement.

Section 14.16 No Third Party Beneficiaries. The terms and provisions of this Agreement are intended solely for the benefit of the Parties and their respective successors and permitted assigns, and it is not the intention of the Parties to confer third-party beneficiary rights upon any other Person other than (a) the Indemnified Parties with respect to Article X hereof and (b) the No Recourse Parties with respect to Section 14.14 hereof.
