(b) At the election of Purchaser, in lieu of indemnifying the Purchaser for its Damages arising under Subclause 7.2(a)(ii)-(viii), Purchaser may require Parent to indemnify the Company for the Company’s Damages. 7.3 Limitations on Indemnification. (a) The Parent and the Company shall not be liable for, and no amounts of indemnification shall be payable in the case of, any claim by an Indemnified Party for breaches by the Company of the representations and warranties set forth in Section 2, other than the Company Fundamental Representations and Subsection 2.11 (Tax Returns and Payments) and except in the case of Fraud, unless and until the Indemnified Parties have suffered, incurred or sustained otherwise indemnifiable Damages hereunder (after giving effect to any Indemnity Reduction Amounts) of an amount equal to $2,500,000 in the aggregate (the “Basket”), in which event the Indemnified Parties shall be entitled to claim indemnity for the full amount of the Damages, from the first dollar, including any such Losses that comprised part of the Basket. (b) Without limiting the generality of the foregoing, the Parent and the Company shall not be liable, with respect to any individual claim or a series of related claims for

42 breaches by the Company of the representations and warranties set forth in Section 2 (other than the Company Fundamental Representations and Subsection 2.11 (Tax Returns and Payments)) and except in the case of Fraud, that results in otherwise indemnifiable Damages (after giving effect to any Indemnity Reduction Amounts), Damages shall not be counted toward satisfaction of the Basket, unless such Damages exceed an amount equal to $250,000. (c) The liability of the Parent and the Company for indemnification of Damages under this Agreement resulting from, arising out of, or relating to (i) any breach of any representations and warranties made by the Company in Section 2 (excluding any Company Fundamental Representation and Subsection 2.11 (Tax Returns and Payments) and except in the case of Fraud) shall be limited, in the aggregate, to an amount equal to ten percent (10%) of the Purchase Price and (ii) any breach of the Company Fundamental Representations, Subsection 2.11 (Tax Returns and Payments) and any covenant, shall be limited, in the aggregate, to an amount equal to the Purchase Price. Any claims under Subsections 7.2(a)(ii), (iii), (iv), (v), (vi), (vii) and (viii) and any claims with respect to Fraud shall not be subject to this Subsection 7.3(c). (d) The amount that an Indemnifying Party is or may be required to pay to an Indemnified Party in respect of Damages for which indemnification is provided under this Agreement shall be reduced by any amounts actually received (including amounts received under insurance policies) by or on behalf of any Indemnified Party or its Affiliates from third parties (net of any costs of recovery of such amounts) and any cash net Tax savings or benefits actually realized by the Indemnified Party or its Affiliates in the taxable year of incurring such Damages (determined on a “with and without” basis) (provided, for this purpose, that a Tax saving shall be deemed realized when the Taxes that would otherwise have been payable by the Indemnified Party would become due and payable, and that any such amount shall be reduced by the costs and expenses incurred in securing such savings) (such amounts and benefits are collectively referred to herein as “Indemnity Reduction Amounts”). If any Indemnified Party or its Affiliates receives any Indemnity Reduction Amounts in respect of a claim for which indemnification is provided under this Agreement after the full amount of such claim has been paid by an Indemnifying Party or after an Indemnifying Party has made a partial payment of such claim and such Indemnity Reduction Amounts exceed the remaining unpaid balance of such claim, then the Indemnified Party shall promptly remit to the Indemnifying Party an amount equal to the excess (if any) of (i) the amount theretofore paid by the Indemnifying Party in respect of such claim, less (ii) the amount of the indemnity payment that would have been due if such Indemnity Reduction Amounts in respect thereof had been received before the indemnity payment was made. Each of the Company and the Purchaser, as appropriate, shall, or shall cause each Indemnified Party to, use its commercially reasonable efforts to pursue promptly any claims or rights it may have against all third parties which would reduce the amount of Damages for which indemnification is provided under this Agreement. Each of the Parent, the Company and the Purchaser, as appropriate, shall use its commercially reasonable efforts to mitigate any Damages hereunder. (e) For the purposes of determining whether a breach of representation or warranty has occurred for the purposes of Subsection 7.2(a) and calculating the amount of Damages related thereto, any qualification as to materiality, “Material Adverse Effect” or any other similar materiality qualification or standard contained in Article 2 of this Agreement or in any certificate or other instrument delivered by or on behalf of the Company pursuant to this Agreement shall be disregarded (it being understood that the word “Material” in the defined term

43 “Material Contract” and the qualification as to “Material Adverse Effect” contained in Subsection 2.9(b) shall not be disregarded for any of such purposes). Notwithstanding anything to the contrary herein, the rights and remedies of any Indemnified Party shall not be limited by the fact that any Indemnified Party (i) had actual or constructive knowledge (regardless of whether such knowledge was obtained through such Indemnified Party’s own investigation or through disclosure by any Parent Group Member, Company Group Member, or any of their representatives or any other Person) of any breach, event or circumstance, whether before or after the execution and delivery of this Agreement or the Closing, or (ii) waived (A) any breach of representation or compliance with any covenant or (B) any condition to the Closing set forth in Section 5. 7.4 Method of Asserting Claims. All claims for indemnification by any Indemnified Party under Section 7 shall be asserted and resolved as follows: (a) Third Party Claims. In the event any claim or demand in respect of which an Indemnified Party might seek indemnity under this Section 7 is asserted against or sought to be collected from such Indemnified Party by a Person other than a party hereto or any of its Affiliates (a “Third Party Claim”), then such Indemnified Party shall deliver an Indemnification Notice to the Person from whom indemnification is being sought (each, an “Indemnifying Party”) reasonably promptly after receipt by such Indemnified Party of notice of such Third Party Claim; provided, however, that the failure by such Indemnified Party to give such notice as provided herein shall not relieve the Indemnifying Party of its indemnification obligation under this Section 7 except to the extent that the Indemnifying Party is actually and materially damaged as a result of such failure. In the event of any such claim for indemnification by the Indemnified Party resulting from or in connection with a Proceeding by a third party, the Indemnifying Party may, at its sole cost and expense, assume the defense thereof; provided, however, that counsel for the Indemnifying Party, who shall conduct the defense of such Proceeding, shall be reasonably satisfactory to the Indemnified Party; and provided, further, that if the Indemnified Party shall have be advised by counsel that there may be legal defenses or rights available to it or them which have not been waived and are in actual or potential conflict with those available to the Indemnifying Party, the Indemnified Party shall have the right to select one law firm reasonably acceptable to the Indemnifying Party to act as separate counsel in addition to any specialized or local counsel, on behalf of the Indemnified Party, at the expense of the Indemnifying Party, in connection with such Proceeding. The Indemnifying Party shall not without the prior written consent of such Indemnified Party consent to entry of any judgment, or enter into any settlement, that (a) provides for injunctive or other non-monetary relief affecting the Indemnified Party or (b) does not include as an unconditional term thereof the giving by each claimant or plaintiff to the Company and the Indemnified Party of a release from all liability with respect to such Proceeding; and if the Indemnified Party is not represented by separate counsel pursuant to the second proviso of the immediately preceding sentence, the Indemnified Party may, at its or their own expenses, participate in any such Proceeding with the counsel of their choice. The Indemnified Party shall not compromise or settle such Proceeding without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed. (b) Direct Claims. In the event of any claim or demand other than a Third Party Claim (a “Direct Claim”), in respect of which an Indemnified Party seeks indemnification under Section 7, the Indemnified Party shall deliver an Indemnity Notice to the Indemnifying Party reasonably promptly after discovering the liability or facts giving rise to such

44 Direct Claim; provided, however, that the failure by such Indemnified Party to give such notice as provided herein shall not relieve the Indemnifying Party of its indemnification obligation under this Section 7 except to the extent that the Indemnifying Party is actually and materially damaged as a result of such failure. The Indemnifying Party shall notify the Indemnified Party within the thirty (30)-day period after its receipt of such Indemnity Notice (the “Dispute Period”) as to whether the Indemnifying Party disputes its liability to the Indemnified Party with respect to the Direct Claim described in the Indemnity Notice (such notice of dispute, an “Indemnity Dispute Notice”). If the Indemnifying Party has delivered an Indemnity Dispute Notice, the Indemnifying Party and the Indemnified Party shall proceed in good faith to negotiate a resolution to such dispute. If the Indemnifying Party and the Indemnified Party cannot resolve such dispute within thirty (30) days after delivery of the Indemnity Dispute Notice, such dispute shall be resolved in accordance with Subsection 9.14 (Dispute Resolution). 7.5 Limitations on Remedies. In the event that indemnification is claimed by any Indemnified Party under Section 7.2(a) due to any (i) any breach of any representations and warranties made by the Parent and the Company in Section 2, or (ii) any nonfulfillment of or failure to perform any covenant on the part of the Company or Parent contained in this Agreement, and any portion of the Damages claimed by such Indemnified Party are attributable to Damages suffered or incurred by the Company and its Subsidiary in connection with such breach or alleged breach (any such Damages, the “Company Losses”), and such indemnification obligation is satisfied by the Company (rather than the Parent) the portion of the indemnifiable Damages that shall be paid to an Indemnified Party that are attributable to the Company Losses shall be calculated as the quotient of (A) the amount of such Company Losses multiplied by a fraction (x) numerator of which is the number of Units then held by such Purchaser and (y) the denominator of which is the then total issued and outstanding Units of the Company (the “Purchaser Position”) divided by (B) one (1) minus the Purchaser Position. 7.6 Exclusive Remedies. From and after the Closing, except in the case of Fraud, the remedies set forth in this Section 7 and in Section 8 and Section 9 shall be the sole and exclusive remedy with respect to any and all claims relating, directly or indirectly, to the subject matter of this Agreement. Without limiting the generality of the foregoing, the Company, on the one hand, and the Purchaser, on the other hand, hereby waive, to the fullest extent permitted under Applicable Law, any and all rights, claims and causes of action it or any of their respective Affiliates may have against the other party or any of its Affiliates with respect to the subject matter of this Agreement, whether arising under or based upon any law. 7.7 Tax Characterization. The parties hereto agree to treat any indemnification payment made pursuant to this Agreement as an adjustment to the Purchase Price for tax purposes, unless otherwise required by Applicable Law. 8. Tax Matters. (a) Partnership Audits. Notwithstanding anything to the contrary herein or in the A&R LLC Agreement either: (i) the Company (and the Company’s “partnership representative” or its “designated individual”, each as defined in the Code, or any equivalent designee under state or local Tax law) shall make or cause to be made an election pursuant to Section 6226 of the Code and under Treasury Regulation Section 301.6227-2(c) (or any

45 corresponding elections under state and local law) with respect to any Tax audit, proceeding, contest or other dispute of the Company (or any of its Subsidiaries that are classified as partnerships for U.S. federal income tax purposes) under the Partnership Audit Rules that relates to a Pre-Closing Tax Period or (ii) (a) the Company shall take such actions as are necessary so that the economic burden of any imputed underpayment under the Partnership Audit Rules or other Tax that relates to a Pre-Closing Tax Period (whether collected through withholding or directly imposed on the Company or any Subsidiary (whether by law, regulation or contract) (a “Pre- Closing Tax Liability”) is not allocated to or borne by Purchaser (including by having the other Members pay their appropriate share to the Company of any Pre-Closing Tax Liability) and (b) the Parent hereby agrees to promptly pay, or cause to be paid, to the Company an amount in cash that is sufficient to fully and timely satisfy any Pre-Closing Tax Liability prior to the due date of such Pre-Closing Tax Liability (such payment not to be treated as a capital contribution for purposes of the LLC Agreement); provided, that if the Parent fails to make such payment described in the foregoing clause (ii)(b), the Company shall reduce the amount that would otherwise be distributable to the Parent pursuant to Section 4.1 of the LLC Agreement on the current or subsequent distribution date (or, if such distribution is not sufficient for that purpose, by so reducing the proceeds of liquidation otherwise payable to the Parent), and the Parent shall be treated for all purposes of this Agreement and the LLC Agreement as having received all distributions (whether before or upon liquidation) unreduced by the amount of such Pre-Closing Tax Liability. (b) Tax Treatment. Unless otherwise required by Applicable Law, the parties hereto intend to treat the purchase of the Purchased Units as a transaction governed by Section 721 of the Code, and no party shall file any Tax Return inconsistent with such treatment. (c) Section 754 Election. To the extent not already made, the Company shall make and maintain at all times a valid election pursuant to Section 754 of the Code and analogous elections under state and local law for the taxable year that includes the Closing, and shall cause each material Subsidiary of the Company that is a partnership for U.S. federal income tax purposes to make and maintain at all times a valid election pursuant to Section 754 of the Code and analogous elections under state and local law for the taxable year that includes the Closing. (d) Allocation of Taxes. For all purposes of this Agreement, in order to apportion appropriately any Taxes relating to a Straddle Period, the portion of any Taxes that are allocable to the Pre-Closing Period shall be (a) in the case of income Taxes and all other Taxes that are not imposed on a periodic basis, the amount that would be payable if the taxable year or period of the applicable entity (and all pass-through entities in which such entity owns a direct or indirect interest) ended on the Closing Date based on an interim closing of the books and (b) in the case of any Taxes that are imposed on a periodic basis (including property Taxes), the amount of such Taxes for the relevant period multiplied by a fraction, the numerator of which shall be the number of calendar days from the beginning of the period up to and including the Closing Date and the denominator of which shall be the number of calendar days in the entire period. 9. Miscellaneous. 9.1 Successors and Assigns. This Agreement will bind and inure to the benefit of the parties hereto and their respective successors and permitted assigns. Nothing in this

THIS SECTION HAS BEEN FULLY DISCUSSED BY EACH OF THE PARTIES HERETO AND THESE PROVISIONS WILL NOT BE SUBJECT TO ANY EXCEPTIONS. EACH PARTY HERETO HEREBY FURTHER WARRANTS AND REPRESENTS THAT SUCH PARTY HAS REVIEWED THIS WAIVER WITH ITS LEGAL COUNSEL, AND THAT SUCH PARTY KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL. (c) The parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement (including Section 4.4) were not performed in

49 accordance with their specific terms or were otherwise breached. It is accordingly agreed that, in addition to any other remedy that may be available, the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to specifically enforce the terms and provisions of this Agreement without the need to post any bond or other security in connection therewith. In furtherance hereof, no party hereto will argue that the remedy of specific performance is unenforceable, invalid or contrary to law for any reason or that the availability of monetary damages (including indemnification under Article VII hereof) would be an adequate remedy for any breach or threatened breach of any of the provisions of this Agreement (including Section 4.4). The parties hereto further agree that, notwithstanding anything to the contrary set forth herein, an injunction or injunctions to prevent breaches of Section 4.4 of this Agreement and to enforce specifically the terms of Section 4.4 of this Agreement shall be the sole and exclusive remedy against Calumet GP and its Affiliates (other than the Company and Parent) with respect to any and all claims relating, directly or indirectly, to the subject matter of this Agreement. Without limiting the generality of the foregoing, except as set forth in the preceding sentence, the Purchaser hereby waives, to the fullest extent permitted under Applicable Law, any and all rights, claims and causes of action it or any of its Affiliates may have against Calumet GP or its Affiliates (other that the Company or Parent) with respect to the subject matter of this Agreement, whether arising under or based upon any law. For the avoidance of doubt, the parties further agree that the Company’s and Parent’s liability for Damages under this Agreement is expressly limited to the provisions of Article VII hereof.
