  Terms/Notes:
  Rate Charged and Maximum Tariff Rate (Max Trf Rate) are shown as unit
  rate on an assumed 100% load factor basis.

  Effective May 1, 2022, this Agreement amends
  and restates the Amended and Restated Transportation
  Service Agreement No. 3227, originally effective
  May 1, 2002, as subsequently amended, restated and/or
  superseded prior to or as of the effective date hereof;
  in particular, this Agreement replaces and supersedes
  that Amended and Restated Transportation Service Agreement
  executed by MRT on October 12, 2021 which was to become


  effective as of August 1, 2022.

  Pursuant to Section 15.8, GT&C of MRT's Tariff, the parties
  have agreed to an extension of the term with respect to all
  of the capacity previously committed under this Agreement.

  Upon providing satisfactory proof of natural gas load reduction
  directly related to a physical production process change
  (e.g., electric arc furnace replacing gas fired blast furnace),
  Customer shall have the right to reduce MDQ by such proven
  load reduction amount.  Any such reduction shall first occur
  under Customer's FTS Agreement #6112.  To the extent the
  proven reduction amount is not satisfied by the MDQ reduction
  under FTS Agreement #6112, an MDQ reduction may occur under
  this Agreement; provided, however that in no event shall
  Customer's total MDQ under this Agreement #3227 and FTS
  Agreement #6112 be reduced to an amount lower than 37,766 Dth/D.
  Any MDQ reduction under this section shall be allocated as follows:
  Market Zone only capacity of up to 10,832 Dth/D shall be reduced
  first with the remaining amount of the proven reduction amount
  5,168 Dth/D allocated to Field to Market Zone capacity. In order
  to exercise its reduction rights under this section, Customer shall
  provide notice of its intent to reduce its MDQ, including full
  particulars and proof satisfactory to MRT of load reduction by
  December 31, 2022 to be effective June 1, 2023.

  Primary Path
  From:  #808527 Waskom - EGT
  To:    #805495 Granite City Steel

  Line Capacities and Line Priorities applicable to services
  provided under this Agreement shall be determined pursuant
  to the provisions of MRT's Tariff (currently set forth at
  GT&C Section 8.2(b)), as subsequently amended and in effect
  from time to time.

  Line Capacity
  West 4,087 Dth/D
  On any given day, the customer is entitled to the greater
  of 4,087 Dth or 4.0% of available West Line capacity.

  Rate Zone Capacities
  Field  42,934 Dth/D
  Market 46,728 Dth/D

  On any day MRT shall not be obligated to receive or
  deliver a cumulative quantity in excess of the MDQ
  set forth in this Agreement.
