(i) On the terms and subject to the conditions contained herein, Provider shall designate Recipient as the recipient of (i) blast furnace coke from Haverhill (“Haverhill Coke”) in an amount equal to the Base Haverhill Coke Tonnage (subject to adjustment as provided in this Section 101) and (ii) blast furnace coke from Jewel (“Jewell Coke”, and together with the Haverhill Coke, the “Sparrows Point Coke”) in an amount equal to the Base Jewell Coke Tonnage (subject to adjustment as provided in this Section 2.01), in each case pursuant to the applicable Coke Supply Agreement, beginning with shipments occurring on or after the closing date of the Purchase Agreement (the foregoing obligation of Provider to designate Recipient as the recipient of Sparrows Point Coke is hereinafter referred to as the “Service”).

(ii) Provider and Recipient acknowledge that (a) Jewell is expected to deliver 58,333 net tons of blast furnace coke per month (the “Expected Jewell Tonnage”) to Recipient (but is only obligated to deliver 690,000 net tons of blast furnace coke per calendar year), Provider and Provider’s affiliates, collectively, pursuant to the Jewell Agreement; and (b) Haverhill is expected to deliver 45,833 net tons of blast furnace coke per month (but is only obligated to delver 539,000 tons of coke per calendar year based upon the “Base Coal Blend” as defined in the Haverhill Agreement), (together with the Minimum Jewell Tonnage the “Expected Combined Coke Tonnage” or “ECCT”) to Recipient, Provider and Provider’s affiliates, collectively, pursuant to the Haverhill Agreement. In each calendar month during the term of this Agreement, in the event the Expected Combined Coke Tonnage is not met through no fault of Provider and for reason(s) beyond Provider’s control, the amount of Haverhill Coke and Jewel Coke to be designated for Recipient during such month shall be automatically adjusted according to the following formulas:

For purposes of the foregoing formulas, the “Amount of Coke Shortfall” shall mean the amount (in net tons), if any, by which the Expected Combined Coke Tonnage during the prior calendar month exceeds the amount of Haverhill Coke and Jewell Coke actually received by Recipient, Provider and Provider’s affiliates, taken as a whole.

For the avoidance of doubt, (i) the Allowable Adjustment for any particular month shall apply separately and in its entirety to the Adjusted Haverhill Coke Tonnage and the Adjusted Jewell Coke Tonnage for such month and (ii) any Adjusted Haverhill Coke Tonnage or Adjusted Jewell Coke Tonnage subject to an Allowable Adjustment from a prior month may be the subject of further Allowable Adjustments in subsequent months in accordance with the foregoing provisions.

Guaranty

NOW, THEREFORE, in consideration of the foregoing and other benefits accruing to the Guarantor, the receipt and sufficiency of which are hereby acknowledged, Guarantor hereby covenants to Jewell and Haverhill as follows:

1. Guarantor guarantees to Haverhill and Jewell the full performance of all Guaranteed Obligations. Guarantor understands, agrees and confirms that Haverhill and Jewell may enforce this Guaranty against the Guarantor without first proceeding against the Guarantor’s Affiliates.

1

2. The liability of Guarantor hereunder shall not be affected or impaired by (a) any other continuing or other guaranty, undertaking or maximum liability of Guarantor, or of any other person, as to the obligations and/or performance of the Guarantor’s Affiliates; (b) any reduction of any such other guaranty or undertaking; (e) any payment made to Haverhill or Jewell in respect of the Guaranteed Obligations which Haverhill, Jewell or their respective affiliates repays to the Guarantor’s Affiliates pursuant to court order in any bankruptcy, reorganization, arrangement, moratorium or other debtor relief proceeding, and Guarantor waives any right to the deferral or modification of its obligations hereunder by reason of any such proceeding commenced by or against any such Guarantor Affiliate; (d) any permitted assignment by Haverhill or Jewell of any of their rights under, as applicable, the Haverhill Contract or the Jewell Contract; or (e) the sale, transfer or other disposition by Guarantor of any or all of its ownership interest in the Guarantor’s Affiliates; provided, notwithstanding any other provision in this Guaranty, no action shall commence against the Guarantor unless and until written notice of default is first made upon the applicable Guarantor’s Affiliate and Guarantor pursuant to the requirements set forth in the Haverhill Contract or, as applicable, the Jewell Contract, and such Guarantor’s Affiliate or the Guarantor fails to cure such default within the applicable cure period set forth in the Haverhill Contract or, as applicable, the Jewell Contract.

3. Other than the notice required to be given to the Guarantor as specified in Section 2 of this Guarantee, Guarantor hereby waives notice of acceptance of this Guaranty and notice of any liability to which it may apply, and waives promptness, diligence, presentment, demand of payment, protest, notice of dishonor or nonpayment of any such liabilities, suit or taking of other action by Haverhill or Jewell against Guarantor.

4.

Other than the notice required to be given to the Guarantor as specified in Section 2 of this Guarantee, no notice to or demand on the Guarantor in any case shall entitle the Guarantor to any other further notice or demand in similar or other circumstances or constitute a waiver of the rights of Haverhill or, as applicable, Jewell to any other or further action in any circumstances without notice or demand. It is not necessary for Haverhill or, as applicable, Jewell to inquire into the capacity or powers of Guarantor’s Affiliates or the officers, directors, or agents acting or purporting to act on its behalf, and any indebtedness made or created in reliance upon the professed exercise of such powers shall be guaranteed hereunder.

7. Subject to Section 2 above, Guarantor waives, to the maximum extent permitted by applicable law, any right to require Haverhill or, as applicable, Jewell to (a) proceed against the Guarantor’s Affiliates or (as applicable) any other person, or (b) pursue any other of its remedies.

8. Guarantor assumes all responsibility for being and keeping itself informed of financial condition and assets of the Guarantor’s Affiliates and of all other circumstances bearing upon the risk of nonpayment or nonperformance of the Guaranteed Obligations and the nature, scope and extent of the risks which the Guarantor assumes and incurs hereunder, and agrees that neither Haverhill or, as applicable, Jewell shall have no duty to advise the Guarantor of information known to it regarding such circumstances or risks.

9. If and to the extent that Guarantor makes any payment or performance to Haverhill or, as applicable, Jewell pursuant to or in respect of this Guaranty, then any claim which the Guarantor may have against the Guarantor’s Affiliates by reason thereof shall be subject and subordinate to the prior payment and performance in full of the Guaranteed Obligations to Haverhill or, as applicable, Jewell.

10. Guarantor hereby agrees to pay all reasonable out-of-pocket costs and expenses of Haverhill or, as applicable, Jewell (including, without limitation, the reasonable fees and disbursements of counsel employed by Haverhill or, as applicable, Jewell) in connection with the enforcement of this Guaranty and any amendment, waiver or consent relating hereto against the Guarantor.

11. Neither this Guaranty nor any provision hereof may be changed, waived, discharged or terminated except with the written consent of Haverhill, Jewell and Guarantor.

12. All notices requests, demands or other communications pursuant hereto shall be made in writing (including telegraphic, telex, facsimile transmission or cable communication)

13. This Guaranty and the rights and obligations of Haverhill, Jewell and Guarantor shall be governed by and construed in accordance with the law of the State of New York, without giving effect to the conflict of laws rules thereof.
