GUARANTY, KEEP WELL FUNDING, AND INDEMNITY

(a) Subject to Section 3.01, the SunCoke Group Obligors hereby, jointly and severally, irrevocably and unconditionally guarantee, for the benefit of each member of the Sunoco Group, the prompt and complete payment and performance when due of each Covered Obligation and in any event prior to the date demand is entitled to be made on any member of the Sunoco Group for the payment or performance thereof.

2.03 Indemnities. Subject to Section 3.01, if (i) Claymont does not pay all or any portion of any payment that becomes due under the Indiana Harbor Note on its Payment Date, or (ii) notwithstanding the undertakings of the SunCoke Group Obligors in respect of the Keep Well Undertakings pursuant to Section 2.02, a SunCoke Group Obligor fails to pay or perform any Covered Obligation and, in either case, a claim is made against a member of the Sunoco Group in respect of such Covered Obligation, then each of the SunCoke Group Obligors, jointly and severally, shall indemnify each member of the Sunoco Group and the other Indemnitees from and against all Liabilities in respect of such Covered Obligations in accordance with the procedures set forth in Section 5.5 of the Separation and Distribution Agreement.

(a) Each SunCoke Group Obligor and Sunoco hereby agrees and confirms that (i) it is the intention of all the parties hereto that the obligations of each SunCoke Group Obligor under Article II not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act (as adopted by any applicable state), the Uniform Fraudulent Transfer Act (as adopted by any applicable state) or any similar federal or state Law to the extent applicable to this Agreement and the obligations of such SunCoke Group Obligor under Article II, and (ii) the aggregate liability of each SunCoke Group Obligor under this Agreement and any additional guaranty or other document executed in accordance with Section 2.04 (collectively, the “Covered Obligation Documents”) at any time (but after giving effect to the right of contribution described in Section 3.02) shall not exceed the maximum amount (as to any SunCoke Group Obligor, its “Maximum Liability”), that will result in the aggregate obligations of such SunCoke Group Obligor under the Covered Obligation

Documents not constituting a fraudulent transfer or conveyance under Bankruptcy Law or any of the other aforementioned acts and Laws.

(b) Each SunCoke Group Obligor agrees that the obligations under the Covered Obligation Documents may at any time and from time to time exceed the Maximum Liability of such SunCoke Group Obligor thereunder without impairing the guaranties or other undertakings under the Covered Obligation Documents or affecting the rights and remedies of any member of the Sunoco Group thereunder.

(c) With respect to each SunCoke Group Obligor, no payment made by Claymont, any other primary obligor, any other SunCoke Group Obligor, or any other Person by virtue of any action or proceeding or any set-off or appropriation or application at any time or from time to time in reduction of or in payment of the Covered Obligations shall be deemed to modify, reduce, release or otherwise affect the liability of such SunCoke Group Obligor under the Covered Obligation Documents, and such SunCoke Group Obligor shall, notwithstanding any such payment (other than any payment made specifically in respect of a Covered Obligation), remain liable for the payment and performance of any remaining Covered Obligations up to the Maximum Liability of such SunCoke Group Obligor until the Covered Obligations have been fully satisfied.

3.02 Rights of Contribution. Each SunCoke Group Obligor hereby agrees that to the extent a SunCoke Group Obligor shall have paid or be obligated to pay more than its proportionate share of any payment made in respect of the Covered Obligations, such SunCoke Group Obligor shall be entitled to contribution from and against any other SunCoke Group Obligor that has not paid its proportionate share of such payment. Each SunCoke Group Obligor’s right of contribution shall be subject to the terms and conditions of Section 3.03. The provisions of this Section 3.02 shall in no respect limit the obligations and liabilities of any SunCoke Group Obligor to any member of the Sunoco Group, and each SunCoke Group Obligor shall remain liable to the members of the Sunoco Group for the payment and performance of the Covered Obligations, up to such SunCoke Group Obligor’s Maximum Liability.

3.03 No Subrogation. Notwithstanding any payment made by any SunCoke Group Obligor hereunder or any set-off or application of funds of any SunCoke Group Obligor by any Indemnitee, no SunCoke Group Obligor shall be entitled to exercise any rights of subrogation against any other SunCoke Group Obligor or any collateral security, guarantee, or right of offset held by any member of the Sunoco Group for the payment of any Covered Obligation.

and delivered in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, pursuant to the terms and conditions of each such applicable document from time to time, and any collateral security, guarantee or right of offset at any time held by any member of the Sunoco Group for the payment of any Covered Obligations may be sold, exchanged, waived, surrendered or released.

Each SunCoke Group Obligor understands and agrees that the guarantee contained in Article II shall be construed as a continuing, absolute, irrevocable and unconditional guarantee of payment and performance, and a primary obligation of each SunCoke Group Obligor, without regard to (i) the validity or enforceability or perfection of any of the Covered Obligations or any other collateral security therefor or guarantee or right of offset with respect thereto at any time or from time to time held by, for, or on behalf of any member of the Sunoco Group, (ii) any defense, set-off or counterclaim whatsoever (other than a defense of payment or performance) which may at any time be available to or be asserted by any SunCoke Group Obligor or any other Person against any member of the Sunoco Group, or (iii) any other circumstance whatsoever (with or without notice to or knowledge of any SunCoke Group Obligor), other than payment or performance, which constitutes, or might be construed to constitute, an equitable or legal discharge of any SunCoke Group Obligor for any of its respective portion of the Covered Obligations or of such SunCoke Group Obligor under the guarantees contained in Article II or any other Covered Obligation Document, in bankruptcy or in any other instance.

(c) When making any demand hereunder or otherwise pursuing its rights and remedies hereunder against any SunCoke Group Obligor, any member of the Sunoco Group may, but shall be under no obligation to, make a similar demand on or otherwise pursue such rights and remedies as it may have against any other SunCoke Group Obligor or any other Person for the Covered Obligations or any right of offset with respect thereto, and any failure by any member of the Sunoco Group to make any such demand, to pursue such other rights or remedies or to collect any payments from any SunCoke Group Obligor or any other Person or to realize upon any such collateral security or guarantee or to exercise any such right of offset, or any release of any other SunCoke Group Obligor or any other Person or any such collateral security, guarantee or right of offset, shall not relieve such SunCoke Group Obligor of any obligation or liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of any member of the Sunoco Group against such SunCoke Group Obligor. For the purposes of this Section 3.05, “demand” shall include the commencement and continuance of any legal proceedings.

(d) All dealings in respect of the Covered Obligations between any of the SunCoke Group Obligors, on the one hand, and any member of the Sunoco Group, on the other hand, shall be conclusively presumed to have been had or consummated in reliance upon the guarantee contained in Article II or in any other Covered Obligation Document.

3.06 Reinstatement. The guarantee contained in Article II shall continue to be effective, or be reinstated, as the case may be, if at any time any payment or performance, or any part thereof, of any of the Covered Obligations is rescinded or must otherwise be restored or returned by any member of the Sunoco Group upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of any SunCoke Group Obligor as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, any SunCoke Group Obligor or any substantial part of its property, or otherwise, all as though such payments had not been made.
